Description

Technical Field

[0001] This utility model relates to the field of insoluble sulfur pulverization technology, specifically to an insoluble sulfur pulverization device with a detachable screen to prevent clogging. Background Technology

[0002] Insoluble sulfur is an excellent rubber vulcanizing agent. Rubber vulcanized with it exhibits optimal anti-blooming properties, effectively preventing scorching of the rubber compound and enhancing the bonding between rubber and metal. It is currently widely used in tires. The chemical name of insoluble sulfur is: homopolymer of sulfur, also known as polymeric sulfur, abbreviated as IS. It is a metastable polymer that is easily reduced to ordinary sulfur when heated or improperly stored. After the production of insoluble sulfur is completed, it needs to be crushed into sulfur particles using crushing equipment.

[0003] Chinese Patent Publication No. CN219682648U discloses an insoluble sulfur pulverizing device, including a pulverizing box. A working box is fixedly connected to the inner top wall of the pulverizing box, and a feed hopper is fixedly connected to the top of the pulverizing box. The bottom end of the feed hopper penetrates the pulverizing box and extends into the interior of the working box. Two pulverizing motors are fixedly installed on the front of the pulverizing box, and the output shafts of the pulverizing motors penetrate the pulverizing box and extend into the interior of the working box. A pulverizing roller is fixedly connected to the output shaft of the pulverizing motor. A sieve bucket is slidably connected to the bottom of the working box. By setting the working box and the sieve bucket, the pulverized insoluble sulfur is restricted. During the upward movement of the sieve bucket, the pulverized insoluble sulfur can be pushed upward to contact the pulverizing roller, thereby avoiding large sulfur particles that may affect subsequent discharge and cause blockage. At the same time, by setting multiple sets of sieve plates, the sulfur particles can be automatically screened and are less prone to blockage.

[0004] However, the aforementioned insoluble sulfur pulverizing device is not convenient to disassemble the screen bucket, and the maintenance and replacement of the screen bucket is quite cumbersome. Therefore, there is an urgent need for an insoluble sulfur pulverizing device with a detachable screen to prevent clogging. Summary of the Invention

[0005] To address the drawback of existing insoluble sulfur pulverizing devices where the screen bucket is difficult to disassemble, leading to cumbersome maintenance and replacement, this invention provides an insoluble sulfur anti-clogging pulverizing device with a detachable screen, which facilitates screen maintenance.

[0006] This utility model provides the following technical solution: an insoluble sulfur anti-clogging crushing device with a detachable screen, comprising a filter box, characterized in that: a crushing mechanism is fixedly connected to the top of the filter box; a discharge port is opened on the left side of the filter box; an inclined screen is arranged inside the filter box; the lower end of the screen passes through the discharge port and extends to the outside; a removal component for limiting the screen is fixedly connected to the left side of the filter box; a support component for supporting the upper end of the screen is fixedly connected to the inner right wall of the filter box; two connecting blocks are fixedly connected to the bottom of the lower end of the screen, and each connecting block has a movable hole at one end; the removal component includes a side rod; a sliding groove is opened at the top of the side rod; a bidirectional lead screw is rotatably arranged in the sliding groove; sliders are threadedly connected to the surfaces of the positive and negative threads of the bidirectional lead screw; positioning rods that can be movably inserted into the movable holes are fixedly connected to the ends of the two sliders that are far apart from each other; and a handle is fixedly connected to the front of the bidirectional lead screw through the side rod.

[0007] Its further features are:

[0008] The crushing mechanism includes a housing, inside which two drive shafts are rotatably connected. Each drive shaft has crushing blades alternately arranged on its surface. A motor is fixedly connected to the left side of the housing. The motor is fixedly connected to one of the drive shafts. The right ends of the two drive shafts pass through the housing and extend to its exterior. The right side surfaces of the two drive shafts are fixedly connected to meshing gears. A large pulley is fixedly connected to the right side of one of the drive shafts.

[0009] The support assembly includes a support plate fixed to the right wall inside the filter box. Multiple springs are fixedly connected to the top of the support plate, and the top of the multiple springs is fixedly connected to the same overlapping plate. The top of the overlapping plate overlaps with the bottom of the upper end of the screen.

[0010] A rotating hole is provided on the right side of the outer casing, and a rotating shaft is rotatably installed in the rotating hole. A cam is fixedly connected to the left side of the rotating shaft, and a small pulley is fixedly connected to the right side of the rotating shaft. The small pulley is connected to a large pulley through a belt.

[0011] A vacuum cleaner is fixedly connected to the left side of the outer casing. The vacuum cleaner's suction end is fixedly connected to a suction pipe, and the vacuum cleaner's exhaust end is fixedly connected to a dust discharge pipe.

[0012] A water tank is fixedly connected to the left side of the outer casing. The end of the dust exhaust pipe away from the vacuum cleaner extends into the water in the water tank. A discharge pipe is fixedly connected to the left side of the outer casing, and a valve is installed on the discharge pipe.

[0013] A dust collection hood is fixedly connected to the inner top wall of the outer casing, and the end of the dust collection pipe away from the vacuum cleaner is fixedly connected to the dust collection hood.

[0014] In the above-described structure of this utility model, when a drive shaft rotates, the large pulley at its right end rotates under the transmission of the belt, causing the small pulley at the right end of the shaft to rotate. This causes the cam to strike the top of the high end of the screen, and under the action of the positioning rod, the movable hole of the connecting block at the bottom of the low end of the screen causes the bottom of the high end of the screen to press against the overlapping plate. Under the action of multiple springs, the high end of the screen moves up and down, preventing material from clogging the screen. When the screen is to be removed, turning the handle causes the bidirectional lead screw to rotate, which in turn drives the two sliders to move closer to each other in the slide groove. This causes the positioning rod to move out of the movable hole of the connecting block at the bottom of the low end of the screen, thus contacting the limit of the screen and allowing it to be removed. This facilitates the removal and maintenance of the screen. By starting the suction fan, the generated dust is sucked into the suction hood and discharged into the water tank through the dust discharge pipe, thereby avoiding dust pollution to the environment and avoiding the risk of explosion due to excessive dust.

The front of the bidirectional lead screw 5 passes through the side rod 4 and is fixedly connected with a handle.

[0022] The crushing mechanism includes a housing 8, inside which two drive shafts 9 are rotatably connected. Each drive shaft 9 has a crushing blade 10 alternately arranged on its surface. A motor 11 is fixedly connected to the left side of the housing 8. The motor 11 is fixedly connected to one of the drive shafts 9. The right ends of the two drive shafts 9 pass through the housing 8 and extend to its outside. The right side surfaces of the two drive shafts 9 are fixedly connected to meshing gears 12. A large pulley is fixedly connected to the right side of one of the drive shafts 9.

[0023] The support assembly includes a support plate 13 fixed to the right wall inside the filter box 1. Multiple springs 14 are fixedly connected to the top of the support plate 13. The top of the multiple springs 14 is fixedly connected to the same overlapping plate 15. The top of the overlapping plate 15 overlaps with the bottom of the high end of the screen 2.

[0024] A rotating hole is provided on the right side of the outer casing 8, and a rotating shaft 16 is rotatably installed in the rotating hole. A cam 17 is fixedly connected to the left side of the rotating shaft 16, and a small pulley is fixedly connected to the right side of the rotating shaft 16. The small pulley is connected to the large pulley through a belt for transmission.

[0025] A vacuum cleaner 18 is fixedly connected to the left side of the outer casing 8. The suction end of the vacuum cleaner 18 is fixedly connected to a suction pipe 19, and the exhaust end of the vacuum cleaner 18 is fixedly connected to a dust discharge pipe 20.

[0026] A water tank 21 is fixedly connected to the left side of the outer casing 8.

[0027] A dust hood 23 is fixedly connected to the inner top wall of the outer casing 8, and the end of the suction pipe 19 away from the vacuum cleaner 18 is fixedly connected to the dust hood 23.

[0028] The working process of this utility model is as follows:

[0029] When pulverizing insoluble sulfur, the material is fed into the inlet at the top of the outer casing 8. One drive shaft 9 is driven to rotate by the motor 11. The two drive shafts 9 are connected by gears 12, causing the other drive shaft 9 to rotate. This, in turn, causes the pulverizing blades 10 to pulverize the material. The pulverized material falls onto the inclined screen 2, where it is screened. Qualified material falls downwards, while larger material is discharged from the discharge port on the left. Simultaneously, as one drive shaft 9 rotates, the large pulley at its right end, driven by the belt, causes the small pulley at the right end of the rotating shaft 16 to rotate, causing the cam 17 to strike. When the top of the high end of the screen 2 is struck, the movable hole of the connecting block 3 at the bottom of the low end of the screen 2 is pressed against the overlapping plate 15 by the positioning rod 7. Under the action of multiple springs 14, the high end of the screen 2 moves up and down to prevent the material from clogging the screen 2. When the screen 2 is removed, the double screw 5 is rotated by turning the handle, which drives the two sliders 6 to move closer to each other in the slide groove. This causes the positioning rod 7 to move out of the movable hole of the connecting block 3 at the bottom of the low end of the screen 2, thus contacting the limit of the screen 2, and the screen 2 can be removed. This makes the screen 2 easy to disassemble and maintain.

[0030] During the crushing process, dust is generated. By starting the suction fan, the generated dust is sucked into the suction hood, passes through the suction pipe 19, and is discharged into the water tank 21 through the dust discharge pipe 20, thereby avoiding dust pollution to the environment and avoiding the risk of explosion due to excessive dust.
