Description

Technical Field

[0001] This utility model relates to the technical field of dust collection equipment for crushers, specifically a dust collection device for crushers. Background Technology

[0002] During operation, crushers generate a large amount of dust, which not only pollutes the environment but also harms the health of operators. The dust collection device for crushers is a specialized device for collecting and treating the dust generated during the crushing process, aiming to improve the working environment and reduce air pollution.

[0003] For example, the utility model patent disclosed in publication number CN219252857U, a dust treatment device for a jaw crusher, relates to the field of dust prevention technology for jaw crushers. The device includes a jaw crusher, with a protective plate slidably connected to the inner side of the jaw crusher. The protective plate has an inclined surface, and a limiting inner plate is fixedly installed on its surface. The limiting inner plate is slidably connected to the inner side of the jaw crusher. With this dust treatment device, the stone material falls onto the inner wall of the feed chute for crushing without resistance. Simultaneously, the protective plate is reset by the elastic force of a compressed second spring, thus providing protection for the feed chute. This method ensures convenient dust protection during stone crushing, reduces the environmental pollution caused by flying dust, and improves the efficiency of dust protection, collection, and emission treatment during stone crushing.

[0004] Although the above-mentioned equipment can collect the dust generated by the crusher, it is not convenient to simultaneously close the feed inlet when the crusher is being fed, which makes it easy for a large amount of dust to escape, thus affecting the efficiency of subsequent collection of dust discharged from the crusher. Therefore, there is an urgent need for a dust collection device for crushers to solve the above-mentioned problems. Utility Model Content

A spray filter screen is slidably engaged at the center of the inner end face of the spray box, and a sealing guide seat is sealed and fixedly engaged at the rear end face of the spray box.

[0011] Preferably, the second rack and the third rack located on the upper and lower sides inside the support box are meshed and connected inside the limiting guide groove by the transmission gear. The transmission structure of the first sealing plate and the second sealing plate is the same, which can facilitate subsequent synchronous up and down displacement transmission.

[0012] Preferably, the upper and lower sets of the first racks are meshed with the guide gear, which facilitates the subsequent sealing and feeding of raw materials by means of the opposite displacement directions of the upper and lower first sealing plates and the second sealing plates, thus preventing a large amount of dust from escaping.

[0013] Preferably, the side faces of both sets of docking seats are fixedly connected to the second sealing plate, which facilitates the subsequent displacement of the second sealing plate by the pen-shaped cylinder through the docking seats, thus facilitating the subsequent feeding operation.

[0014] Preferably, the fixed duct is coaxially aligned with the exhaust fan, which can effectively improve the stability and accuracy of guiding the dust after extraction, and improve the efficiency of subsequent filtration.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0016] 1. This utility model uses two sets of first and second sealing plates with reverse transmission to achieve layered isolation when feeding material into the crusher opening, preventing dust from escaping and thus improving the environmental performance of the equipment.

[0026] The limiting guide groove 12 is provided in two sets, and the two sets of limiting guide grooves 12 are symmetrically opened on the side wall of the support box 5. The transmission gear 9 is rotatably engaged at the middle of the inner end face of the limiting guide groove 12, and the guide gear 11 is rotatably engaged between the two sets of transmission gears 9 on the inner end face of the support box 5.

[0027] The lower end face of the second sealing plate 6 located on one side is provided with a second rack 8, and the lower end face of the second rack 8 is provided with a first rack 7. The lower end face of the second sealing plate 6 located on the other side is provided with a third rack 10. The first sealing plate 1 and the second sealing plate 6 are provided with the same configuration.

[0028] The dust collection device 2 includes a support guide 26, five sets of exhaust fans 25 are equidistantly arranged on the inner end face of the support guide 26, and a spray box 23 is fixedly arranged at the center of the rear end face of the support guide 26. Five sets of fixed ducts 24 are equidistantly arranged on the front end face of the spray box 23, and water pipes 27 are symmetrically arranged on the side end face of the spray box 23. A spray filter screen 22 is slidably snapped into the center of the inner end face of the spray box 23, and a sealing guide 21 is sealed and fixedly snapped into the rear end face of the spray box 23.

[0029] The second rack 8 and the third rack 10 located on the upper and lower sides inside the support box 5 are meshed and connected by the transmission gear 9 inside the limiting guide groove 12. The transmission structure of the first sealing plate 1 and the second sealing plate 6 is the same, which can facilitate subsequent synchronous up and down displacement transmission.

[0030] The upper and lower sets of first racks 7 are meshed with guide gears 11, which facilitates the subsequent sealing and feeding of raw materials by means of the opposite displacement directions of the upper and lower first sealing plates 1 and second sealing plates 6, thus preventing a large amount of dust from escaping.

[0031] Both sets of docking brackets 3 have their side ends fixedly connected to the second sealing plate 6, which facilitates the subsequent movement of the pen-shaped cylinder 4 through the docking brackets 3, making it convenient for subsequent material feeding operations.

When feeding material into the crusher, the user can start the two sets of pen-shaped cylinders 4. At this time, the pen-shaped cylinders 4 can drive the docking seat 3 to move outward, so that the two sets of second sealing plates 6 at the top begin to separate. When the second sealing plates 6 move outward, the two sets of second sealing plates 6 can move outward synchronously through the meshing of the second rack 8, the third rack 10 and the transmission gear 9, thereby providing a guiding space for feeding. At the same time, the second rack 8... When rack 8 moves outward, it can drive rack 7 to move outward. At this time, rack 7 can drive rack 7 at the bottom corresponding to the first sealing plate 1 to move inward through guide gear 11. At this time, the two sets of first sealing plates 1 at this time can repeat the reverse displacement of rack 8, rack 10 and transmission gear 9, thereby closing the opening at the bottom of the support box 5. When the bottom is completely closed, the user loads materials. When unloading materials, the above steps are repeated. At this time, the second sealing plate 6 closes and the first sealing plate 1 opens to unload materials. At the same time, five sets of exhaust fans 25 can draw in dust and remove it through the spray filter screen 22.
