Detailed Description
The invention is further described below with reference to the accompanying drawings.
Referring to fig. 1 to 10, the present invention provides a novel drying device, which includes a tank body 1 having legs and a rotating
If a plurality of conveyor belts are involved, the arrangement of the conveyor belts is required to be started from the conveyor belt with the minimum distance Hmin to the conveyor belt with the maximum distance Hmax.
Wherein, the lower end of the spiral lifting knife is connected with the rotating shaft through a horizontal connecting plate 8 parallel to the bottom of the tank body, and a gap smaller than 2% of the diameter of the inner wall of the cylinder body is formed between the horizontal connecting plate and the bottom of the tank body; the front edge of the horizontal connecting plate facing the rotating direction of the rotating shaft is provided with a single-side edge 8-1 for guiding materials to the horizontal connecting plate; the lower edge of the chopping knife is provided with a cutting edge for crushing materials; the spiral chopping knife is connected with the rotating shaft through the connecting rod, the connecting rod comprises a small connecting rod 9-1 and a large connecting rod 9-2 which can be sleeved, the small connecting rod end of the connecting rod is connected with the chopping knife, the large connecting rod end of the connecting rod is connected with the rotating shaft, so that materials are saved due to the fact that the small connecting rod end is sleeved with the chopping knife, the first gap is adjusted in the later period conveniently, and the sleeved portion is welded well after the first gap is determined so as to be fixed.
The minimum distance Hmin is 0-4% of the diameter of the inner wall of the cylinder; the maximum distance Hmax is 1-10% of the diameter of the inner wall of the cylinder; the distance minimum Hmin is less than the distance maximum Hmax. Here Hmin and Hmax are both present to eliminate a certain amount of the sticking on the inner wall of the cylinder, which can be seen in fig. 5 after the chopper is unfolded, for example, after the first conveyor belt rotates around the tank, some material between the chopper wheels in the height direction is not touched, but only by the rotation of the following conveyor belts, all the material is touched, thereby eliminating the sticking problem. Therefore, through the setting of this distance, can adjust the volume of barrel inner wall sizing, guarantee user demand. For example, the distance Hmin is 0% or 1% of the diameter of the inner wall of the cylinder, the distance Hmax is 6% or 5% of the diameter of the inner wall of the cylinder, and the like, and the values are set differently according to different materials.
The value of the first clearance is controlled within 0-2% of the diameter of the inner wall of the cylinder; the value of the second gap is controlled within 0-2% of the diameter of the inner wall of the cylinder. The implementation values are respectively 0.1%, 0.2%, 0.3%, 0.5%, 1% and 1.5% according to different materials; and the operating value of the second clearance may also be 0.1%, 0.2%, 0.3%, 0.5%, 1%, 1.5%, etc.
The distance formed in the height direction between the upper edge of the lifting knife and the lower edge of the last chopping knife of each conveyor belt is smaller than the maximum distance Hmax, so that the material on the lifting knife can be conveniently conveyed to the chopping knives, but the functions of the chopping knives are maintained.
The barrel body comprises an upper barrel body 3-1 and a lower barrel body 3-2, the outer wall of the barrel body is subjected to heat preservation treatment, the two barrel bodies are connected and sealed through flanges, a plurality of threaded holes 10 are formed in flanges of the upper barrel body, stepped
The heat medium flow passage comprises a barrel, wherein a plurality of transverse partition plates 12 and longitudinal partition plates 13 are arranged in an interlayer of the barrel at equal intervals, the transverse partition plates and the longitudinal partition plates are crossed with all the transverse partition plates in a cross mode, a heat medium flow passage is formed between every two adjacent partition plates, a flow guide hole 14 is formed in each partition plate and is located on one side of each longitudinal partition plate, flow guide holes in each partition plate are located on two sides of each longitudinal partition plate, the heat medium flow passage on the upper layer flows to the heat medium flow passage on the lower layer through the flow guide hole on the upper layer, and the heat medium flow passage on the lower layer.
The side wall of the upper cylinder is provided with a
The lower cylinder body is also provided with a
The lower end face of the upper cylinder flange and the upper end face of the lower cylinder flange are positioned through a step face.
The baffle body comprises a fixing plate 6-1, a baffle 6-2 and a connecting plate 6-3, wherein the fixing plate is consistent with the radian of the inner wall of the cylinder body, the baffle 6-2 is used for blocking materials, the connecting plate 6-3 is connected between the baffle and the fixing plate, an included angle of 25-65 degrees is formed between the baffle and the fixing plate, a long strip-shaped through hole 6-4 is formed in the fixing plate and is connected to the inner wall of the cylinder body, a nut is fixed on the inner wall of the cylinder body generally, and then the baffle.
Due to the limitation of the height position of the baffle body, the length of the chopping knife of each conveying belt positioned at the highest layer is different, and the lengths and the shapes of the chopping knives at other positions are completely consistent.
The above structure can be adjusted in practice, and the bottom-most shredding knife can be set to have different lengths, and when the principle is designed in the foregoing, the lengths of other shredding knives will be the same, including the top-most shredding knife, as can be seen in fig. 6 after the shredding knives are unfolded.
In the implementation process of the embodiment, the fixing between the connecting plate or the connecting rod and the rotating shaft is realized through a sleeve, the sleeve is locked on the rotating shaft through a bolt, and the connecting plate and the connecting rod are welded and fixed with the sleeve.
After the material that needs the mummification gets into jar body through the feed inlet, after the discharge gate is closed, the pivot begins to rotate, the material slowly mentions the superiors from jar body bottom through the conveyer belt and cuts up the sword, promote the in-process because the effect of centrifugal force, the material can be got rid of to the barrel inner wall along the knife face, because heat medium can follow the intermediate layer in heat transfer for the barrel inner wall, and then carry out the mummification dehydration to the material, and the material that has been heated is because the preceding mummification of back material extrusion is expected before, realize with new old replacement mode, the dry material that the replacement was come out promotes the sword superiors and cuts up the sword again, material on the sword of cutting up is caught and is kept off back sword jar bottom with the material behind the baffle, through calculating speed. According to the invention, under the condition that the blade development diagram shows, the lifting knife and the chopping knife can scrape the materials on the inner wall of the cylinder, and the chopping operation of the chopping knife in the process of upward climbing of the materials is kept, so that thorough and efficient drying is realized. The first gap in the implementation is also critical and can directly affect the drying efficiency. Therefore, the structure is considered comprehensively, and the effect is realized by a plurality of factors together.
The barrel under this application has also carried out special design, can carry out effective car processing, and the lathe of being convenient for is installed, and the hot medium of going up the barrel leads down the barrel behind the connecting sleeve in addition, can not appear revealing in two flange joint departments, has ensured the sealed of hot medium, adopts reciprocating type runner simultaneously, can effectively ensure the heating effect to the barrel, the guarantee mummification.
Therefore, the structure can effectively ensure the implementation of subsequent drying.
The above description is only a preferred embodiment of the present invention, and should not be construed as limiting the present invention, and all equivalent variations and modifications made in the claims of the present invention should be covered by the present invention.
