The dry powder box 30 is fixedly arranged inside the movable groove, and a powder delivery pipe 31 is provided on the surface of the dry powder box 30. The powder delivery pipe 31 is fixedly connected to the dry powder box 30, and one end of the powder delivery pipe 31 is fixedly connected to the starting box 32.

[0037] In the present embodiment, electrical equipment is arranged inside the cabinet 19. During use, when the temperature inside the cabinet 19 is too high, the temperature sensor 41 will feedback and start the second motor 34. The second motor 34 starts to drive the surface screw to rotate. The screw rotation drives the surface sliding bellows 36 to move up and down to perform heat dissipation. At the same time, heat can be dissipated through the heat dissipation holes on the surface of the cabinet door 26.

[0038] The working principle of this embodiment is as follows: the technicians place the rotary kiln 2 above the base 1, and at this time, the first rotating wheel 6 is rotated, and the first rotation drives the bidirectional screw 5 to rotate, and the bidirectional screw 5 drives the first clamping block 7 to move toward each other and enter the second clamping groove 8, so as to fix the rotary kiln 2 horizontally, which reduces the labor cost, improves the installation efficiency, and is convenient for installation and disassembly. At this time, the second rotating wheel 14 is rotated again, and the second rotating wheel 14 drives the cross bar 13 to rotate, and the cross bar 13 drives the second bevel gear 16 to rotate, and the second bevel gear 16 drives the first bevel gear 15 to rotate, and the first bevel gear 15 drives the screw 12 to rotate, and the screw 12 drives the second clamping block 17 to translate, and when the second clamping block 17 translates to the inside of the third clamping groove 10, it stops rotating. At this time, the vertical direction of the rotary kiln 2 is also fixed, which reduces the labor cost, improves the installation efficiency, and is convenient for installation and disassembly. At the same time, the arrangement of the first bevel gear 15 and the second bevel gear 16 improves the overall portability of the installation of the base 1, and the arrangement of the heat dissipation holes 18 helps the rotary kiln 2 to effectively dissipate heat during operation. Heat, the rubber layer is used to increase the friction between the card block and the card slot surface, thereby improving the fixing efficiency. The cabinet 19 is equipped with electrical equipment. During use, when the temperature inside the cabinet 19 is too high, the temperature sensor 41 will feedback and start the second motor 34. The second motor 34 starts to drive the surface screw to rotate, and the screw rotation drives the surface sliding bellows 36 to move up and down to perform heat dissipation work. At the same time, heat can be dissipated through the heat dissipation holes on the surface of the cabinet door 26. When a fire occurs inside the cabinet, the power-off device 42 will block the current in the rotary furnace. The device has its own stored electricity. The temperature sensor 41 senses too high and starts the first motor 22. The first motor 22 starts to rotate the surface shaft 23, and the gear 24 on the surface of the shaft 23 will mesh with the rack 25, so that the cabinet door 26 is deeply closed to block the heat dissipation holes on the surface. At this time, the oxygen content inside the cabinet is reduced, and the fire extinguishing device is started to spray dry powder to extinguish the fire, so that the fire source is extinguished, achieving the effect of self-extinguishing, reducing the long-distance rotary furnace, the long distance of rescue work and the situation where there is no time for rescue.

[0039] The above description is only a preferred embodiment of the present invention and does not limit the present invention in other forms. Any technician familiar with the profession may use the technical content disclosed above to change or modify it into an equivalent embodiment with equivalent changes and apply it to other fields.
