However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0023] Example 1: As Figure 1 - Figure 4 As shown, this utility model provides an integrated equipment for crushing and screening potassium perchlorate, including a crushing mechanism 1 and a screening mechanism 2. The bottom of the crushing mechanism 1 and the top of the screening mechanism 2 are fixedly installed.

Multiple crushing discs 17 are uniformly fixedly connected to the outer wall of the active rod 14. The output end of the crushing motor 13 is fixedly connected to one end of the active rod 14. A chain 15 is engaged at one end of the active rod 14. One end of a driven rod 16 is engaged with the inner side of the chain 15, and multiple crushing discs 18 are uniformly fixedly connected to the outer wall of the driven rod 16. The top of the body 11 is welded to the bottom of the feeding frame 12, and the machine... The bottom of the body 11 is welded to the top of the discharge frame 19. An electric valve 110 is fixedly connected to the bottom of the discharge frame 19. The crushing mechanism 1 also includes a negative pressure pump 111, a controller 112, a negative pressure pipe 113, a fan 115, a pipe 116, and a protective shell 117. Two side plates 10 are symmetrically fixedly connected to the inner wall of the body 11, and a spiral cooling pipe 118 is fixedly installed inside the side plate 10. A circulating cooling box 120 is fixedly connected inside the protective shell 117. A pump body 119 is fixedly connected to the bottom of the circulating cooling box 120. One end of the spiral cooling pipe 118 passes through the body 11 and is fixedly connected to one end of the pump body 119, and the other end of the spiral cooling pipe 118 passes through the body 11 and is fixedly connected to the top of the circulating cooling box 120.

[0024] The specific settings and functions of this embodiment are described below: During the crushing process, the ventilator 115 is turned on. The ventilator 115 draws the dust-laden air inside the machine body 11 to the dust removal equipment through the pipe 116. The combination of the negative pressure pump 111 and the ventilator 115 helps to control the spread of dust, reduce the safety hazards caused by excessive dust concentration, and prevent dust from drifting outward and accumulating around the equipment to form an explosive environment, thereby improving the safety of the equipment. During the crushing process, the pump body 119 delivers the low-temperature coolant in the circulating cooling tank 120 to the spiral cooling pipe 118. The coolant flows upward spirally through the spiral cooling pipe 118, which promptly removes the heat generated during the crushing process, preventing the temperature from becoming too high due to heat accumulation and reducing the possibility of accidents such as explosions caused by high temperatures.

[0025] Example 2: Figure 1 - Figure 3 As shown, one end of the negative pressure pipe 113 is fixedly connected to the inner wall of one end of the body 11, and the other end of the negative pressure pipe 113 is fixedly connected to one end of the negative pressure pump 111. A pressure sensor 114 is fixedly connected to the inner wall of the top of the body 11. One end of the pipe 116 is fixedly connected to the inner wall of one end of the body 11, and the other end of the pipe 116 is fixedly connected to one end of the ventilator 115. The pressure sensor 114 and the negative pressure pump 111 are both electrically connected to the controller 112. A driven rod 16 is rotatably installed at the top of the inside of the body 11. The screening mechanism 2 includes a base 21, a screening motor 22, a rotating rod 23, and a screening frame 25. The output end of the screening motor 22 is fixedly connected to one end of the rotating rod 23. A movable rod 24 is rotatably connected to one end of the rotating rod 23. One end of the movable rod 24 is rotatably installed to one end of the screening frame 25. The top of the base 21 is fixedly installed to the bottom of the body 11.

[0026] The overall effect of this embodiment is that the negative pressure pump 111 operates under negative pressure inside the machine body 11 through the negative pressure pipe 113. The air pressure sensor 114 can monitor the air pressure inside the machine body 11 in real time and transmit the data to the controller 112. The controller 112 automatically adjusts the negative pressure pump 111 according to the feedback data and adopts a negative pressure operation mode to keep the inside of the machine body 11 under a certain negative pressure environment, so that external air is difficult to enter the machine body 11 during the subsequent crushing process of potassium perchlorate particles inside the machine body 11.

[0027] The method of use and working principle of this device: When crushing and screening potassium perchlorate particles, the fan 115 is connected to the dust removal equipment, and the potassium perchlorate particles are fed into the crushing chamber of the machine body 11 at a uniform speed through the feeding frame 12. The top of the feeding frame 12 is sealed, and the negative pressure pump 111 and the air pressure sensor 114 are turned on through the controller 112. The negative pressure pump 111 operates under negative pressure inside the machine body 11 through the negative pressure pipe 113. The air pressure sensor 114 can monitor the air pressure inside the machine body 11 in real time and transmit the data to the controller 112. The controller 112 automatically adjusts the negative pressure pump 111 according to the feedback data and adopts the negative pressure operation mode to keep the inside of the machine body 11 under a certain negative pressure environment, so that external air is difficult to enter the machine body 11 during the subsequent crushing process of potassium perchlorate particles inside the machine body 11.

[0028] The crushing motor 13 is started, which drives the driving rod 14 and the driven rod 16 to rotate the crushing disc 17 and the crushing disc 18 at high speed. The potassium perchlorate particles are subjected to impact, cutting and friction with the inner wall of the machine body 11 by the crushing disc 17 and the crushing disc 18 in the crushing chamber. After repeated cutting, they are gradually crushed into smaller particles. During the crushing process, the ventilator 115 is turned on. The ventilator 115 draws the dust-laden air in the machine body 11 to the dust removal equipment through the pipe 116. The combination of the negative pressure pump 111 and the ventilator 115 helps to control the spread of dust, reduce the safety hazards caused by excessive dust concentration, and prevent dust from drifting outward and accumulating around the equipment to form an explosive environment, thereby improving the safety of the equipment.

[0029] After the crushing operation is completed, the electric valve 110 is opened, and the crushed potassium perchlorate material is smoothly conveyed to the screening mechanism 2 through the discharge frame 19. The screening motor 22 drives the rotating rod 23 to rotate. The rotating rod 23 is connected to the screening frame 25 through the movable rod 24, so that the screening frame 25 starts to shake and vibrate at a preset frequency. The material jumps and rolls on the screen. Materials of different particle sizes are separated according to the size of the screen mesh of the screening frame 25. Materials with a particle size larger than the screen mesh size remain on the screening frame 25, while materials that are within the range of the screen mesh size of the screening frame 25 fall into the collection device for collection, ensuring screening efficiency and accuracy.

[0030] Meanwhile, the inner wall of the machine body 11 is provided with a hollow side plate 10, and a spiral cooling pipe 118 is installed inside the side plate 10. During the crushing process, the circulating cooling tank 120 and the pump body 119 are turned on. The pump body 119 delivers the low-temperature coolant (such as special heat transfer oil) in the circulating cooling tank 120 to the spiral cooling pipe 118. The coolant flows upward spirally through the spiral cooling pipe 118, which takes away the heat generated during the crushing process in time, avoids the temperature from being too high due to heat accumulation, and reduces the possibility of accidents such as explosion caused by high temperature. Finally, the coolant flows back to the circulating cooling tank 120 to realize the recycling of the coolant.

[0031] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the present utility model.
