Description

Technical Field

[0001] This utility model relates to the field of tunnel slag utilization technology, and in particular to a tunnel slag resource utilization device. Background Technology

[0002] Mine debris is waste generated during the construction of tunnels and underground projects. The composition of mine debris mainly depends on the geological conditions of the construction site. It usually contains rock fragments, soil, sand and gravel. In some special geological areas, mine debris may also contain minerals, groundwater and other components. In the process of resource utilization of mine debris, crushing equipment is often used to crush it for easy recycling.

[0003] In daily work, when crushing existing caving debris, impact crushers are often used. When the rotor inside the device rotates at high speed and drives the caving debris to move, some smaller pieces of debris will be hit by strong impacts and fly out in the opposite direction along the feed inlet, which can easily cause accidental injury to the surrounding operators. At the same time, it is not easy to prevent dust. Utility Model Content

[0004] The purpose of this invention is to solve the problems in the existing technology where small cavitary debris can fly out in the reverse direction along the feed inlet due to strong impact and is not easy to prevent dust, and proposes a cavitary debris resource utilization device.

[0005] To achieve the above objectives, this utility model adopts the following technical solution: a tunnel slag resource utilization device, including an impact crusher, an impact frame inside the impact crusher, a rotor body inside the impact crusher, and an auxiliary device on the surface of the impact crusher. The auxiliary device includes an extension frame fixed to the surface of the impact crusher, two cover plates rotatably connected to the inner wall of the extension frame, auxiliary blocks fixedly connected to both sides of the cover plates, positioning rods fixedly connected to the surface of the auxiliary blocks, positioning grooves on both sides of the extension frame, and the positioning rods slidably connected to the inner walls of the positioning grooves. Reset parts are provided on both sides of the extension frame, and a dust suction assembly is provided between the impact crusher and the extension frame. Through these components, when tunnel slag enters the extension frame, its weight compresses the two cover plates, causing them to open in conjunction with the auxiliary blocks and reset parts. After losing weight, the reset parts drive the auxiliary blocks and cover plates to reset. The positioning rods, in conjunction with the positioning grooves, prevent the cover plates from rotating in the opposite direction and limit the rotation angle of a single cover plate to less than 90 degrees, thus blocking flying stones.

[0006] Preferably, the reset part includes a fixing plate fixed to the surface of the extension frame. Two sliding rods are fixedly connected to the surface of the fixing plate. A top plate is slidably connected to the surface of the sliding rods. A reset spring is sleeved on the surface of the sliding rods. The two ends of the reset spring are fixedly connected to the surfaces of the fixing plate and the top plate, respectively. Through the above components, the reset spring can cooperate to drive the top plate to reset, and the top plate, in cooperation with the auxiliary block, can drive the cover plate to reset.

[0007] Preferably, a gasket is fixedly connected to the surface of the cover plate, and the gasket can buffer the impact of a flying stone when it hits the cover plate.

[0008] Preferably, the two book covers are positioned in the middle of the extension frame.

[0009] Preferably, the dust collection assembly includes a housing fixed to the surface of the impact crusher, an air extractor fixedly connected to the inner wall of the housing, a suction pipe fixedly connected to the surface of the extension frame, a filter element connected to the other end of the suction pipe via a flange, and the other end of the filter element fixedly connected to the input end of the air extractor via a flange.

[0010] Preferably, the inner wall of the extension frame is fixedly connected with an intercepting net.

[0011] Preferably, the filter element includes a dust collection tank and a filter cloth, wherein the filter cloth is fixed in the inner wall of the dust collection tank.

[0012] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0013] 1. In this utility model, by setting an auxiliary device, adding an extension frame and an openable cover plate structure, the opening and closing of the cover plate is controlled by the weight of the slag itself. It opens when the slag is being discharged, and after the discharge is completed, the reset part drives the auxiliary block and the cover plate to quickly reset. At the same time, the positioning rod cooperates with the positioning groove to prevent the cover plate from rotating in the opposite direction. It also limits the rotation angle of a single cover plate to less than 90 degrees, which can block flying stones and effectively prevent small fragments from flying out of the feed port due to the strong impact caused by the rotor driving the slag movement. This greatly reduces the safety threat to the operators and reduces the probability of dangerous accidents.

[0014] 2. In this utility model, by setting up a dust suction component, the dust generated during the crushing process can be actively sucked up. The air pump sucks the dust into the filter element through the suction pipe. After being filtered by the dust filter cloth, the dust collection tank collects the dust, which reduces the spread of dust in the working environment and significantly improves the working environment.

A dust collection component 33 is provided between the impact crusher 1 and the extension frame 31.

[0025] In this embodiment: When feeding, the slag enters the extension frame 31. Due to its weight, it will squeeze the two cover plates 32. The cover plates 32, together with the auxiliary block 35 and the reset part 34, open. After losing weight, the reset part 34 drives the auxiliary block 35 and the cover plates 32 to reset. The positioning rod 36, together with the positioning groove 37, prevents the cover plates 32 from rotating in the opposite direction. At the same time, it limits the rotation angle of a single cover plate 32 to less than 90 degrees, which can block flying stones.

[0026] Specifically, the reset part 34 includes a fixing plate 341 fixed to the surface of the extension frame 31. Two slide rods 343 are fixedly connected to the surface of the fixing plate 341. A top plate 342 is slidably connected to the surface of the slide rods 343. A reset spring 344 is sleeved on the surface of the slide rods 343. The two ends of the reset spring 344 are fixedly connected to the surfaces of the fixing plate 341 and the top plate 342, respectively.

[0027] In this embodiment: the reset spring 344 can work together to drive the top plate 342 to reset, and the top plate 342, in conjunction with the auxiliary block 35, can drive the cover plate 32 to reset.

[0028] Specifically, a gasket 38 is fixedly connected to the surface of the cover plate 32, and the gasket 38 can buffer the impact of flying stones on the cover plate 32.

[0029] Specifically, the two book cover plates 32 are set in the middle of the extension frame 31.

[0030] Specifically, the dust collection component 33 includes a housing 332 fixed to the surface of the impact crusher 1. An air extractor 334 is fixedly connected to the inner wall of the housing 332. A suction pipe 331 is fixedly connected to the surface of the extension frame 31. A filter element 335 is connected to the other end of the suction pipe 331 through a flange.

An interception net 333 is fixedly connected to the inner wall of the extension frame 31. The filter element 335 includes a dust collection tank 3351 and a dust filter cloth 3352. The dust filter cloth 3352 is fixed in the inner wall of the dust collection tank 3351.

[0031] In this embodiment: During crushing, the vacuum pump 334 is turned on. The vacuum pump 334, together with the suction pipe 331, sucks in the crushed dust into the filter element 335. The dust filter cloth 3352 in the filter element 335 filters and collects the dust. The flange connection allows the whole unit to be disassembled and cleaned.

[0032] Working principle: During crushing, the slag is poured into the extension frame 31. Due to its weight, the slag will compress the two cover plates 32. The cover plates 32 drive the auxiliary block 35 to rotate, and the auxiliary block 35 compresses the top plate 342. The return spring 344 is under force, and the positioning rod 36 cooperates with the positioning groove 37 to limit the rotation angle of a single cover plate 32 to less than 90 degrees. After the slag is discharged, it loses its weight, and the return spring 344 drives the top plate 342 to return to its original position. The positioning plate cooperates with the auxiliary block 35 to drive the cover plate 32 to return to its original position. The positioning rod 36 cooperates with the positioning groove 37 to prevent the cover plate 32 from rotating in the opposite direction, which can block flying stones. The gasket 38 can provide cushioning. At the same time, during crushing, the exhaust fan 334 is turned on. The exhaust fan 334 cooperates with the suction pipe 331 to suck up dust. The filter element 335 filters and collects the dust to reduce dust pollution.
