The dust cover completely seals the crushing chamber, preventing dust from scattering and polluting the air and environment.

Description

Technical Field

[0001] This utility model belongs to the field of coconut shell processing technology, specifically a dust suppression device for crushing coconut shell particles. Background Technology

[0002] The coconut husk is composed of leathery coarse fibers, which are strong, tough, and have a high lignin content. Because the coconut shell is hard and does not deform under cold or heat, it is difficult to break. The crusher is an important machine for crushing coconut shells in the production of coconut shell activated carbon, which is related to the efficiency of the subsequent carbonization of coconut shells.

[0003] When coconut shells are crushed into small pieces, a large amount of fibrous dust is generated due to the dust attached to the shells and the fibrous structure of the shells themselves. This dust pollutes the surrounding air and the working environment, thus affecting the normal work of the workers. Utility Model Content

[0004] To overcome the above-mentioned defects, this utility model provides a dust suppression device for crushing coconut shell particles, which solves the problem that a large amount of fibrous dust is generated during the crushing process, thereby polluting the surrounding air and working environment, and thus affecting the normal work of workers.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a dust suppression device for crushing coconut shell pellets, comprising a support frame, a crushing chamber connected to the support frame, a first motor fixedly installed on one side of the support frame, a protective box connected to the other side of the support frame, a dust cover connected above the crushing chamber, a filling port connected to one side of the crushing chamber, a discharge port connected below the crushing chamber, and a first rotating rod and a second rotating rod rotatably installed inside the crushing chamber via bearings;

[0006] Gears are connected to one end of both the first and second rotating rods. Crushing rollers are fixedly installed on both the first and second rotating rods. A liquid storage tank is connected above the dust cover. A sliding groove is opened on the inner wall of the dust cover. A dust filter plate is connected to the inner wall of the dust cover. A second motor is fixedly installed on one side of the dust cover. A lead screw is connected to the output shaft of the second motor. A mating block is threadedly installed on the lead screw.

[0007] A connecting strip is connected below the mating block, a scraper is connected below the connecting strip, an injection pipe is connected above the liquid storage tank, a liquid pump is connected to the liquid storage tank through a pipe, transport pipes are connected to both sides of the liquid pump, one end of the transport pipe passes through the dust cover and is connected to a connecting plate, and multiple spray heads are connected and installed on the connecting plate.

[0008] As a further embodiment of this utility model: the output shaft of the first motor is connected to the first rotating rod, the gear at one end of the first rotating rod meshes with the gear at one end of the second rotating rod, and the gears at one end of both the first rotating rod and the second rotating rod are housed inside the protective box.

[0009] As a further embodiment of this utility model: a sealing plate is rotatably connected to the filling port, and the inner wall of the crushing chamber located on both sides of the crushing roller is designed with a slope.

[0010] As a further embodiment of this utility model: a guide groove is provided in the middle of the dust filter plate, and the connecting strip slides in the guide groove.

[0011] As a further embodiment of this utility model: the scraper is located below the dust filter plate and is in close contact with the dust filter plate; the connecting strip and the mating block are connected together on both sides by a folded dust cover; the width of the folded dust cover is the same as the width of the guide groove, and one end of the folded dust cover is connected to the wall of the sliding groove.

[0012] As a further embodiment of this utility model: the lead screw is rotatably connected to the dust cover via a bearing and is located in the slide groove, and the mating block slides in the slide groove and contacts the slide groove wall.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] 1. This dust suppression device for crushing coconut shell pellets consists of a dust cover, a liquid storage tank, a liquid pump, a transport pipe, a connecting plate, and spray nozzles. During crushing, the operator starts the liquid pump, which draws liquid from the storage tank through the pipe and transports it to the connecting plate. The spray nozzles then create a high-pressure water waterfall. The water waterfall wets the coconut shells through the holes in the dust filter plate, preventing dust adhering to the coconut shells from scattering during crushing. The wet coconut shells are also less likely to form fibrous dust during crushing, thus reducing the direct formation of dust. The dust cover encloses the crushing chamber, sealing it and preventing dust from scattering and polluting the air and environment.

[0015] 2. This dust suppression device for crushing coconut shell pellets comprises a second motor, a lead screw, a mating block, a connecting strip, a guide groove, a scraper, and a dust filter plate. During crushing, the dust filter plate blocks dust particles, preventing them from clogging the spray nozzle. The second motor rotates the lead screw, causing the mating block, which is threaded into the lead screw, to slide along the lead screw in the groove. The mating block, through the connecting strip, drives the scraper, causing it to move along the guide groove below the dust filter plate, thereby scraping off the dust adhering to the filter plate and preventing clogging.

Detailed Implementation

[0021] The technical solution of this patent will be further described in detail below with reference to specific embodiments.

[0022] like Figure 1-4 As shown, this utility model provides a technical solution: a dust suppression device for crushing coconut shell particles, including a support frame 1, a crushing chamber 2 connected to the support frame 1, a first motor 3 fixedly installed on one side of the support frame 1, the output shaft of the first motor 3 connected to a first rotating rod 8, a gear 10 at one end of the first rotating rod 8 meshing with a gear 10 at one end of a second rotating rod 9, and both gears 10 at one end of the first rotating rod 8 and the second rotating rod 9 are set in a protective box 4, the protective box 4 covers and protects the gears 10 at one end of the first rotating rod 8 and the second rotating rod 9 to prevent particles from hitting and damaging the gears 10.

[0023] A protective box 4 is connected to the other side of the support frame 1. A dust cover 5 is connected above the crushing chamber 2. A filling port 6 is connected to one side of the crushing chamber 2. A sealing plate 25 is rotatably connected to the filling port 6. The inner wall of the crushing chamber 2 located on both sides of the crushing roller 11 is designed with a slope. The rotating sealing plate 25 can facilitate the opening or sealing of the filling port 6 by the staff, thereby preventing dust from drifting out of the filling port 6 when the sealing plate 25 is closed.

[0024] A discharge port 7 is connected to the bottom of the crushing chamber 2. A first rotating rod 8 and a second rotating rod 9 are rotatably installed in the crushing chamber 2 via bearings. A gear 10 is connected to one end of the first rotating rod 8 and the second rotating rod 9. Crushing rollers 11 are fixedly installed on the first rotating rod 8 and the second rotating rod 9. A liquid storage tank 12 is connected to the top of the dust cover 5. A sliding groove 13 is opened on the inner wall of the dust cover 5. A dust filter plate 14 is connected to the inner wall of the dust cover 5. A guide groove 26 is opened in the middle of the dust filter plate 14. The connecting strip 18 slides in the guide groove 26. The movement of the connecting strip 18 is guided by the guide groove 26, so that the scraper 19 can move smoothly. The dust filter plate 14 can block dust particles and prevent dust particles from adhering to and hitting the spray head 24.

[0025] A second motor 15 is fixedly installed on one side of the dust cover 5. The output shaft of the second motor 15 is connected to a lead screw 16. The lead screw 16 is rotatably connected to the dust cover 5 through a bearing and is located in the slide groove 13. The mating block 17 slides in the slide groove 13 and contacts the groove wall of the slide groove 13. Through the contact between the groove wall of the slide groove 13 and the mating block 17, the slide groove 13 can restrict the mating block 17, thereby preventing the mating block 17 from rotating or tilting on the lead screw 16, so that the mating block 17 can move smoothly and directionally.

[0026] A mating block 17 is threaded onto the lead screw 16. A connecting strip 18 is connected below the mating block 17, and a scraper 19 is connected below the connecting strip 18. The scraper 19 is located below the dust filter plate 14 and is in close contact with the dust filter plate 14. Folded dust cover cylinders 27 are connected to both sides of the connecting strip 18 and the mating block 17. The width of the folded dust cover cylinder 27 is the same as the width of the guide groove 26, and one end of the folded dust cover cylinder 27 is connected to the wall of the slide groove 13. An injection pipe is connected above the storage tank 12. 20. The liquid storage tank 12 is connected to the liquid pump 21 through the pipeline. The liquid pump 21 is connected to the two sides of the transport pipe 22. One end of the transport pipe 22 passes through the dust cover 5 and is connected to the connecting plate 23. Multiple spray heads 24 are connected and installed on the connecting plate 23. When the mating block 17 moves along the lead screw 16, the folded dust cover cylinders 27 on both sides of the mating block 17 will deform respectively, thereby covering the lead screw 16 and blocking the guide groove 26 in real time, preventing dust and water mist from directly contacting the lead screw 16 and causing corrosion.

[0027] The working principle of this utility model is as follows:

[0028] By starting the first motor 3 to rotate the first rotating rod 8, the meshing of the gear 10 at one end of the first rotating rod 8 and the gear 10 at one end of the second rotating rod 9 enables the crushing rollers 11 on the first rotating rod 8 and the second rotating rod 9 to rotate synchronously. Then, coconut shells are filled in through the filling port 6, and the crushing rollers 11 are used to crush them. At this time, the liquid pump 21 will draw liquid from the storage tank 12 through the pipeline and transport it to the connecting plate 23 through the transport pipe 22, so that it can be sprayed out from the spray head 24 to crush the filled coconut shells. The coconut shell is moistened to prevent dust adhering to it from scattering when it is broken. The moistened coconut shell is also less likely to form fibrous dust when it is broken. The dust that is not adsorbed will be blocked by the dust filter plate 14. Then, the second motor 15 is started to rotate the lead screw 16, which causes the mating block 17 to slide along the lead screw 16 in the slide groove 13. This causes the mating block 17 to drive the scraper 19 through the connecting strip 18, which causes the scraper 19 to move along the guide groove 26 below the dust filter plate 14, thereby scraping off the dust adhering to the dust filter plate 14.
