[0002] The calcination process of aluminum phosphide tablets usually involves mixing red phosphorus and aluminum powder in a certain proportion, and then mixing, ramming and calcining through a specific device. Aluminum phosphide tablets are widely used. The phosphine gas released by them has strong insecticidal activity and can be used to control various stored-grain pests and their pupae and eggs. It is mainly used for airtight fumigation and insecticidal treatment of items such as grain, tobacco, medicinal materials, bamboo ware, fur, tea, spices, nuts, etc., and can also be used to control borers of forest trees and fruit trees and field rodents in caves.

[0003] The existing technology has the following deficiencies: During the calcination process of aluminum phosphide tablets, the aluminum phosphide raw materials need to be compacted. When the existing calcination tank compacts the raw materials, the mixed raw materials are likely to adhere to the inner wall of the calcination tank, and at the same time, it is impossible to stably compact different positions at the bottom of the calcination tank, resulting in insufficient compaction of the raw materials of aluminum phosphide tablets, which will affect the calcination effect.

[0027] The present utility model provides a Figure 1 shown aluminum phosphide tablet calcining device, including a reaction chamber 1 for calcining aluminum phosphide tablets, and further including:

[0028] A calcining mechanism 2, arranged inside the reaction chamber 1, for storing the mixed raw materials of aluminum phosphide tablets;

[0029] A compaction mechanism 3, arranged inside the calcining mechanism 2, for compacting the mixed raw materials of aluminum phosphide tablets.

[0030] For the convenient discharging operation of the calcined aluminum phosphide tablets, as Figures 1-3As shown in the figure, the calcination mechanism 2 includes a tank body 201, which is movably installed on the inner wall of the top of the reaction chamber 1. A cover plate 202 is fixedly installed on the inner top of the tank body 201. One end of the inner wall of the cover plate 202 is fixedly installed with a feed pipe 203. A blanking pipe 204 is fixedly installed at the bottom of the tank body 201. A piston plate 206 is arranged inside the blanking pipe 204. When the electric push rod 205 works, the piston plate 206 can move towards the inside of the blanking pipe 204, so that the calcined aluminum phosphide tablets can be conveniently discharged through the blanking pipe 204.

[0031] In order to fully compact the raw materials of the aluminum phosphide tablets, as Figures 1-2 and Figure 4 shown in the figure, the compaction mechanism 3 includes a mounting gear 301, which is rotatably installed at the middle position of the inner wall of the cover plate 202. The bottom of the mounting gear 301 penetrates through the inner wall of the cover plate 202 and is fixedly sleeved with a connecting rod 302. A cleaning plate 303 is fixedly installed on the outside of the connecting rod 302. A hydraulic cylinder 304 is fixedly installed on the top of the mounting gear 301. The output end of the hydraulic cylinder 304 penetrates through the inner wall of the mounting gear 301 and is fixedly installed with a fixed bent rod 305. A pressing plate 306 is fixedly installed at the bottom of the fixed bent rod 305. When the mounting gear 301 rotates, the cleaning plate 303 can clean the inner wall of the tank body 201. At the same time, when the hydraulic cylinder 304 works, the pressing plate 306 can fully compact the mixed raw materials on the top of the piston plate 206.

[0032] In order to provide power for the rotation of the pressing plate 306 and the cleaning plate 303, as Figure 2 shown in the figure, a servo motor 307 is fixedly installed at one end of the top of the cover plate 202. The output end of the servo motor 307 is fixedly sleeved with a rotating gear 308. The rotating gear 308 meshes with the mounting gear 301. The cover plate 202 can install and fix the servo motor 307. When the servo motor 307 works, through the meshing action between the rotating gear 308 and the mounting gear 301, the cleaning plate 303 and the pressing plate 306 rotate.

[0033] In order to conveniently clean the inner wall of the tank body 201, as Figure 2 and Figure 4 shown in the figure, the top view cross-section of the cleaning plate 303 is set as a fan-shaped structure. The three cleaning plates 303 are arranged in an equally spaced circular arrangement. The outer walls of the three cleaning plates 303 are movably connected to the inner wall of the tank body 201. The three equally spaced cleaning plates 303 can conveniently clean the inner wall of the tank body 201 and can prevent the raw materials from adhering to the inner wall of the tank body 201.

[0034] In order to make the calcined aluminum phosphide tablets be conveniently discharged, as Figures 2-4As shown, the outer diameter of the blanking pipe 204 is the same as that of the tank body 201, the inner diameter of the blanking pipe 204 is the same as that of the tank body 201, the outer diameter of the piston plate 206 is smaller than the inner diameter of the blanking pipe 204, the diameter of the pressing plate 306 is larger than the radius of the piston plate 206, and the diameter of the piston plate 206 is smaller than the inner diameter of the blanking pipe 204, so that the calcined aluminum phosphide tablets can be conveniently discharged through the gap between the piston plate 206 and the inner wall of the blanking pipe 204.

[0035] In order to conveniently discharge the calcined aluminum phosphide tablets, as Figure 2 and Figure 3 shown, an electric push rod 205 is fixedly installed at the bottom inside the blanking pipe 204, and the output end of the electric push rod 205 is fixedly connected to the bottom of the piston plate 206. The blanking pipe 204 can install and fix the electric push rod 205. When the electric push rod 205 works, it can drive the piston plate 206 to move, so that the calcined aluminum phosphide tablets can be conveniently discharged.

[0036] During the calcination process of the aluminum phosphide tablets, the mixed raw materials can be added into the tank body 201 through the feeding pipe 203. Then, when the servo motor 307 works, the rotating gear 308 rotates. Through the meshing of the gear parts, the installation gear 301 rotates, which can drive the connecting rod 302 and the cleaning plate 303 to rotate, so that the cleaning plate 303 can clean the inner wall of the tank body 201, avoiding the adhesion of the raw materials of the aluminum phosphide tablets to the inner wall of the tank body 201. At the same time, the rotation of the installation gear 301 can drive the hydraulic cylinder 304 and the pressing plate 306 to rotate. Then, when the hydraulic cylinder 304 works, the pressing plate 306 can compact the raw materials at different positions on the top of the piston plate 206, avoiding the situation that the insufficient compaction of the raw materials affects the calcination effect. When the calcination is completed, the electric push rod 205 works to make the piston plate 206 move downward, so that the calcined aluminum phosphide tablets can be discharged through the gap between the piston plate 206 and the inner wall of the blanking pipe 204, making the device convenient for subsequent calcination work of the aluminum phosphide tablets and improving the calcination efficiency of the aluminum phosphide tablets. This embodiment specifically solves the problems in the prior art that the raw materials of the aluminum phosphide tablets are easy to adhere to the inner wall of the firing tank and the insufficient compaction of the raw materials will affect the calcination effect.

[0037] Only some exemplary embodiments of the present invention are described by way of illustration above. Undoubtedly, for those of ordinary skill in the art, without departing from the spirit and scope of the present invention, the described embodiments can be modified in various different ways. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the protection scope of the claims of the present invention.
