Detailed Description

The following are specific embodiments of the present invention and are further described with reference to the drawings, but the present invention is not limited to these embodiments.

As shown in fig. 1 and 5, the tower incineration system includes a base frame 11, an incineration tower 12 and a feeding conveyor belt 2, a spiral material guiding and storing pipe 3 is disposed on an inner wall of the incineration tower 12, an upper end of the material guiding and storing pipe 3 is a feeding end, the feeding end is connected with a feeding pipe 31 extending out of the incineration tower 12, a lower end of the material guiding and storing pipe 3 is a discharging end, the discharging end is connected with a discharging pipe 32 extending out of the incineration tower 12, a notch 33 is disposed on the material guiding and storing pipe 3, the notch 33 is parallel to the material guiding and storing pipe 3, the notch 33 faces to a middle portion of the incineration tower 12, a heat source 13 is disposed at a bottom of the incineration tower 12, and an outlet pipe 34 is formed by shrinking a top portion of the.

The paste waste is conveyed to the top of the tower through the feeding conveyer belt 2, the waste is conveyed to the feeding pipe 31 in a state of controlling the flow rate through a hopper, the heat source 13 at the bottom of the incineration tower 12 provides a high-temperature environment for waste incineration, so that the waste is continuously incinerated in the process of flowing from top to bottom, the temperature of the waste in the guide material storage pipe 3 is gradually increased from top to bottom due to the fact that hot gas circulates from bottom to top, and the heated paste material is easy to circulate. As the notch 33 is arranged on the material guiding and storing pipe 3, hot gas can be fully contacted with waste products, and potential safety hazards caused by high-temperature reaction or expansion of the waste products are avoided.

The lower side edge of the notch 33 and the axis of the material guiding and storing pipe 3 are in the same horizontal plane, and an inclination angle of 30-70 degrees is formed between the plane shared by the upper side edge of the notch 33 and the axis of the material guiding and storing pipe 3 and the horizontal plane. The notch 33 is arranged to: the waste product has the region of circulation, the storage area that guide storage pipe 3's bottom inner wall corresponds promptly, in order to improve the utilization to waste gas, the inside roof of guide storage tank need be and carry out the fender eaves form of collecting to steam, and the steam that the material that the storage area burns produced goes upward through the guide storage tank spiral to improve heat utilization efficiency and incineration efficiency, according to the particular case who burns the waste product, control unloading speed.

The heat source 13 is an electric furnace, a vent pipe 35 positioned at the lower half section of the incineration tower 12 is arranged on the incineration tower 12, and the vent pipe 35 is communicated with the inside and the outside of the incineration tower 12.

As shown in fig. 2, 3 and 4, the feeding and conveying belt 2 includes a plurality of rotating wheels and a conveying chain drawn on the rotating wheels, the conveying chain includes a plurality of chain links 4 connected end to end, the chain links 4 include a rectangular accommodating frame 41, two ends of the accommodating frame 41 are respectively provided with a rotating drum 42 and a rotating shaft 43, and two side walls of the accommodating frame 41 are respectively provided with two guide grooves 44; the distance between the two guide grooves 44 on the same side wall of the accommodating frame 41 is gradually reduced from one end to the other end, the two guide grooves 44 on the same side wall of the accommodating frame 41 are symmetrically arranged, the chain link 4 further comprises two guide rods 45 which are parallel to each other, two ends of each guide rod 45 are respectively connected in the two guide grooves 44 which are opposite to the two side walls of the accommodating frame 41 in a sliding manner, a soft pocket 46 is connected between the two guide rods 45, the two guide rods 45 are connected to an opening of the pocket 46, a supporting plate 47 which can support the pocket 46 is fixedly arranged on the accommodating frame 41, and a discharge hole 48 is formed between the supporting plate 47 and the accommodating frame 41; a convex rib 49 is fixedly arranged on the outer side surface of the supporting plate 47, and a limiting groove which can correspond to the convex rib 49 is arranged on the rotating wheel; two ends of the guide rod 45 are respectively connected with a tension spring 51, two ends of the tension spring 51 are respectively connected with the guide rod 45 and the containing frame 41, and the tension spring 51 has the tendency of pulling the two guide rods 45 to be close to each other.

The waste material is at the in-process of carrying to the top of the tower, if directly adopt open-air conveyor such as band conveyer, not only causes the condition such as drip easily, causes the potential safety hazard, but also can have waste product part volatile matter to atmospheric emission, causes the pollution of environment, in this scheme, adopts "from closing from opening" formula pocket 46, makes the waste product be in relative inclosed environment in transportation process, opens automatically when being in the position of falling the material.

When the two guide rods 45 are connected with the pocket 46 and are not weighted, the tension spring 51 drives the pocket to move upwards, namely the guide rods 45 move towards one end of the two guide grooves 44 at the same side, which is far away from each other, specifically, in the process of material ascending, if the pocket 46 is not weighted, the tension spring 51 drives the pocket 46 and the guide rods 45 to move upwards, the distance between the upper ends of the two guide grooves 44 at the same side is large, the opening of the pocket 46 is in an open state, the pocket 46 is filled with waste products, the pocket 46 is weighted to overcome the downward movement of the tension spring 51, under the action of the guide grooves 44, the two guide rods 45 are close to each other to seal the opening of the pocket 46, certainly, the opening of the pocket 46 is not completely closed, only the opening of the pocket 46 is reduced to the maximum extent, when the pocket 46 runs to a top folding position, the bearing load of the pocket 46 acts on the support plate 47, the tension spring 51 acts on the, the flow of waste also causes the opening of the pocket 46 to tend to open, thus allowing for closed transfer and automatic opening of the waste with a return.

And the inner wall of the incineration tower 12 is provided with a supporting strip 6 parallel to the material guide and storage pipe 3, and the outer wall of the bottom of the material guide and storage pipe 3 is abutted against the supporting strip 6.
