Referring to fig. 1, the vibrating fluidized calcining apparatus 100 according to the embodiment of the first aspect of the present application includes a housing 110, a fluidizing box 120, a transmission shaft and a high temperature air pipe 140, wherein the fluidizing box 120 is located inside the housing 110, one end of the transmission shaft is used for connecting a vibration source 200, and the other end of the transmission shaft is connected to the fluidizing box 120 to drive the fluidizing box 120 to vibrate relative to the housing 110. The high temperature air duct 140 has an upper end penetrating the bottom wall of the fluidization tank 120 to communicate with the fluidization tank 120, and a lower end communicating with a high temperature air source (not shown). The gap between the fluidization tank 120 and the housing 110 is sealed by a plurality of high temperature resistant soft seal strips 170.

This vibration fluidization calcining device 100's fluidization box 120 is independent of the casing 110 vibration, can reduce the fluidization wind pressure, vibrates the material fully, makes the material obtain the heating uniformly, and does benefit to heating temperature's stability to guarantee material attribute that can be better has better calcination effect. Under the condition that the temperature of the high-temperature air is the same, compared with the indirect heat exchange mode that the medium of the fluidized material entering the fluidizing box body 120 is only common air and the heating air source sweeps the outer surface of the fluidizing box body 120 to heat the fluidizing box body 120, the high-temperature air is used as the medium of the fluidized material and the heat source of the heated material simultaneously in the vibrating fluidizing calcination device 100, so that the utilization rate of the heat in the high-temperature air can be improved, and the calcination temperature of the material can be improved. The gap between the fluidization box 120 and the housing 110 is sealed by a plurality of high temperature resistant soft sealing strips 170, which allows the fluidization box 120 to vibrate independently from the housing 110, and simultaneously avoids air leakage from the fluidization chamber (not shown), thereby realizing high-efficiency high-temperature calcination.

The structure and the mutual positional relationship of the components of the vibrating fluidized calcining apparatus 100 according to the embodiment of the first aspect of the present application are described below.

Referring to fig. 1, the vibrating fluidized calcining apparatus 100 includes a housing 110, a fluidizing box 120, a first transmission shaft 131, a second transmission shaft 132 and a high temperature air duct 140.

Wherein, the fluidization box 120 is a vibration component of the vibration fluidization calcining device 100, the first transmission shaft 131 and the second transmission shaft 132 are connected to the fluidization box 120, and the first transmission shaft 131 and the second transmission shaft 132 have the same structure and are symmetrically arranged relative to the gravity center of the fluidization box 120. Taking the first transmission shaft 131 as an example, the upper end of the first transmission shaft 131 penetrates the housing 110 and is connected to the bottom wall of the fluidization box 120, the lower end is used for connecting the vibration source 200, and the first transmission shaft 131 drives the fluidization box 120 to vibrate under the vibration of the vibration source 200. The arrangement can sufficiently and uniformly vibrate the materials in the fluidization box body 120, so that the materials are sufficiently heated, and the calcination effect is improved.

Referring to fig. 2, the housing 110 includes a high temperature resistant steel layer 117, a nano-microporous layer 118, and a stainless steel layer 119, which are sequentially attached. The refractory steel layer 117 is an inner layer (i.e., a side close to the fluidization box 120), and has a physical property of high temperature resistance, can withstand the high temperature inside the casing 110, and still has a good strength; the nanoporous layer 118 is an intermediate thermal insulation layer that can mitigate heat transfer from the interior of the housing 110 to the exterior; stainless steel layer 119 is an outer layer of housing 110, and may be 304 steel, for example, to prevent rust and corrosion. As can be readily appreciated, the shell 110 is able to withstand higher material calcination temperatures and better insulate against heat loss due to heat transfer to the exterior of the shell 110.

Referring to fig. 1 again, the housing 110 includes a first transmission shaft through hole 111, a second transmission shaft through hole 112, a high temperature air pipe through hole 113, a housing discharge pipe 114, a housing feed pipe 115, and a housing air outlet 116. The first transmission shaft 131 penetrates through the first transmission shaft through hole 111, the second transmission shaft 132 penetrates through the second transmission shaft through hole 112, and the high temperature air pipe 140 penetrates through the high temperature air pipe through hole 113.

Housing outlet pipe 114 is located in the sidewall of housing 110, fluidization tank 120 includes fluidization tank outlet pipe 122, and fluidization tank outlet pipe 122 is located inside housing outlet pipe 114.

The shell feeding pipe 115 and the shell air outlet 116 are positioned on the upper side of the shell 110, the materials enter the interior of the shell 110 from the shell feeding pipe 115, and the high-temperature wind carries the gases decomposed by the calcination of the animal materials and leaves the interior of the shell 110 from the shell air outlet 116.

It will be readily appreciated that the high temperature wind serves both as a medium for fluidizing the material and as a heat source for heating the material. The utilization rate of heat in high-temperature air can be improved; on the other hand, since the fluidization tank 120 is directly exposed to the high-temperature wind, not only can the fluidization tank 120 be uniformly heated, but also the internal temperature stress of the fluidization tank 120 due to temperature unevenness is prevented.

Referring to fig. 4, a porous distribution plate 150 is disposed inside the fluidization tank 120, a plurality of through holes 151 are uniformly disposed on the porous distribution plate 150, and the porous distribution plate 150 divides the inside of the fluidization tank 120 into a uniform flow chamber 152 and a vibrating fluidization chamber 153. The flow equalizing chamber 152 is located at the lower part of the vibrating fluidizing chamber 153, and the flow equalizing chamber 152 is communicated with the vibrating fluidizing chamber 153 through a plurality of through holes 151.

One end of the high-temperature air pipe 140 enters the bottom of the flow equalizing chamber 152, high-temperature air enters the flow equalizing chamber 152 from the bottom, and is uniformly and uniformly blown into the vibrating fluidizing chamber 153 through the plurality of through holes 151 after being equalized by the flow equalizing chamber 152, so that the materials in the vibrating fluidizing chamber 153 are uniformly fluidized.

Further, referring to fig. 1, a gap between the high temperature air duct through hole 113 and the high temperature air duct 140, a gap between the first transmission shaft 131 and the first transmission shaft through hole 111, a gap between the second transmission shaft 132 and the second transmission shaft through hole 112, and a gap between the housing discharge pipe 114 and the fluidization box discharge pipe 122 are sealed by a high temperature resistant soft seal tape 170.

It is easy to understand that the fluidizing box 120 is a component vibrating relative to the housing 110, but the gas pressure inside the vibrating fluidizing chamber 153 can affect the calcining effect of the material, so that it is beneficial to maintain as good a tightness of the fluidizing chamber as possible for the performance of the whole vibrating fluidizing calcining apparatus 100. As the fluidization tank 120 vibrates, the first drive shaft 131, the second drive shaft 132, the high temperature flue pipe 140, and the fluidization tank discharge pipe 122 all vibrate relative to the housing 110. These gaps can cause the fluidization chamber to leak, and the high temperature resistant soft seal band 170 can sealingly connect the four components throughout the housing 110 and still allow each component to vibrate relative to the housing 110.

Referring to fig. 3, in some embodiments of the present disclosure, the high temperature resistant soft sealing tape 170 includes a first high temperature resistant fabric layer 171, an aluminum silicate cotton layer 172, and a second high temperature resistant fabric layer 173, which are sequentially attached. The aluminum silicate cotton layer 172 has the advantages of light volume weight, high temperature resistance, good thermal stability, low thermal conductivity, good mechanical vibration resistance and the like, and can ensure that the high temperature resistant soft sealing tape 170 can still keep good sealing performance at high temperature.

In other embodiments, the high temperature resistant soft sealing band 170 may be other flexible cloth materials capable of withstanding high temperature.

Referring again to fig. 1, optionally, the vibrating fluidized calcining apparatus 100 further includes a shield 160, and the shield 160 is installed inside the housing 110 and is used for collecting the high temperature air above the vibrating fluidizing chamber 153 and the gas decomposed from the calcining of the material and leaving the inside of the housing 110 from the housing outlet 116. The cover 160 exposes the housing air outlet 116 and the housing feeding pipe 115, a second opening 161 is provided at the lower end of the cover 160, a first opening 121 is provided at the upper end of the fluidization box 120, and the first opening 121 is sleeved with the second opening 161. It is easily understood that when the fluidization tank 120 vibrates, the shield 160 is stationary with the housing 110, and the first opening 121 and the second opening 161 have a gap therebetween and are sleeved with each other.

Further, the gap between the first opening 121 and the second opening 161 is connected by a high temperature resistant soft sealing tape 170, so that the gas decomposed by the high temperature wind and the material calcination can timely leave the inside of the housing 110 from the housing air outlet 116 after passing through the mask 160 from the vibrating fluidization chamber 153, and the sealing performance of the vibrating fluidization chamber 153 is improved.

Referring to fig. 1, in some embodiments of the present application, a first material stop valve 191 is disposed in the shell feeding pipe 115, and a second material stop valve 192 is disposed in the shell discharging pipe 114 to control the powder flow rate. The first material blocking valve 191 and the second material blocking valve 192 can be installed by purchasing existing components, and the structure of the existing components is not described in detail herein.

Referring to fig. 1, in some embodiments of the present application, the top of the housing 110 is further provided with a viewing window 180 to facilitate a worker to observe the material vibrating and fluidizing calcination status in the vibrating and fluidizing chamber 153. This part belongs to the prior art, and therefore, the detailed structure and installation method of the observation window 180 will not be further described herein.

The fluidizing and calcining apparatus 100 of the first aspect of the present application, with the fluidizing box 120 as an independent vibrating component, can uniformly vibrate the material, which is beneficial to uniformly heating the material. Furthermore, the high-temperature air pipe 140 is directly communicated with the flow equalizing chamber 152, and is conveyed to the vibrating fluidizing chamber 153 after flow equalizing to heat and fluidize the material, so that the calcining temperature and the fluidizing effect are improved; by using the high-temperature resistant soft sealing strip 170, the gap between the fluidization box 120 and the shell 110 is flexibly sealed, so that the sealing performance of the vibrating fluidization chamber 153 is further improved, the pressure loss in the vibrating fluidization chamber 153 is reduced, and the calcining effect is improved; the shell 110 has the characteristics of high temperature resistance and good heat insulation, can bear the severe working conditions of high-temperature calcination materials, and has better safety and reliability. The vibrating fluidizing calcination device 100 can achieve the calcination temperature of about 700-850 ℃, and is a vibrating fluidizing device capable of high-temperature calcination.

The lower extreme of first transmission shaft 131 and the lower extreme of second transmission shaft 132 all connect in the upside of base body 211, and when vibrating motor was in the vibration mode, under vibrating motor's effect, base body 211 vibrates to drive first transmission shaft 131 and the vibration of second transmission shaft 132, first transmission shaft 131 and the vibration of second transmission shaft 132 drive fluidization box 120 vibration, thereby realize the vibration to the material.

Referring to fig. 7 and 8, in some embodiments of the present disclosure, a cooling water path 230 is disposed inside the base body 211 to cool the base body 211.

The cooling water circuit 230 comprises a water inlet pipe 231 and a water outlet pipe 232, and a water cooling cavity 233 is arranged between the water inlet pipe 231 and the water outlet pipe 232. Considering that the base body 211 needs to vibrate, the water-cooling cavity 233 is kept in a full water state, which is beneficial to the vibration of the base body 211.

In some embodiments of the present application, the water-cooled chamber 233 can be maintained in a water-full state to facilitate vibration of the base body 211.

Specifically, the inside of the base body 211 has a cavity, the grill 234 is located inside the base body 211 and divides the cavity into a plurality of cells, and the water inlet pipe 231 is communicated with the water inlet cell 2341 near the side wall of the base body 211. Wherein, the lower extreme of grid 234 and the interior diapire butt of base body 211, the upper end of grid 234 is less than base cover 235 of base body 211 to make into water cell cavity 2341 and adjacent middle cell cavity 2342 and top gap 2343 intercommunication. The outlet pipe 232 is communicated with the small outlet cell cavity 2344 close to the side wall of the base body 211, and the outlet pipe 232 is located at the highest position of the small outlet cell cavity 2344. The water inlet pipe 231, the water inlet small cell cavity 2341, the plurality of middle small cell cavities 2342, the water outlet small cell cavity 2344 and the water outlet pipe 232 penetrate and are configured as the cooling water path 230. As can be easily understood, the small water inlet cell cavity 2341 and the small water outlet cell cavity 2344 are two different small cell cavities, and after cooling water enters the small water inlet cell cavity 2341 from the water inlet pipe 231, the cooling water can only flow into the middle small cell cavity 2342 adjacent to the top gap 2343 after being filled with water. The plurality of middle cells 2342 are sequentially filled with water through the gaps at the tops thereof until the cooling water flows into the water outlet cells 2344. After the small water outlet cell 2344 is filled with cooling water, the cooling water flows out of the base body 211 through the water outlet pipe 232 from the highest position of the small water outlet cell 2344.

Further, the cooling water path 230 in some embodiments of the present application is arranged with two cooling water paths, namely a first cooling water path 236 and a second cooling water path 237, and the first cooling water path 236 and the second cooling water path 237 are symmetrically arranged on both sides of the base body 211 in the width direction.

Referring to fig. 5, the base 300 includes an upper platform 310 and a lower platform 320, the upper platform 310 carries the housing 110 of the vibrating fluidized calcining apparatus 100, the lower platform 320 carries the base body 211 of the vibrating base 210, and a plurality of sets of vibration isolation springs 330 are disposed between the base body 211 and the lower platform 320.

Referring to fig. 5 and 9, in some embodiments of the present disclosure, a mounting portion 2111 is disposed at each of four corners of the lower side of the base body 211, and one mounting portion 2111 is used for mounting one isolation spring 330. As can be readily appreciated, the isolation springs 330 can mitigate the effects of the vibration of the base body 211 on the base 300, thereby improving the safety of the entire vibrating fluidized calcining system 400.

In the vibrating fluidized calcining system 400 of the embodiment of the second aspect of the present application, two vibrating motors are used to drive the base body 211 to vibrate, and further drive the fluidizing box 120 to vibrate, so that the material can be uniformly vibrated; meanwhile, the cooling water path 230 is arranged inside the base body 211, so that the safety of the vibration source 200 can be improved, the vibration frequency can be improved, and the vibration effect on the material can be enhanced.

It should be noted that the features of the embodiments in the present application may be combined with each other without conflict.

The above description is only a preferred embodiment of the present application and is not intended to limit the present application, and various modifications and changes may be made by those skilled in the art. Any modification, equivalent replacement, improvement and the like made within the spirit and principle of the present application shall be included in the protection scope of the present application.
