Description

Technical Field

[0001] This utility model relates to the technical field of stone processing equipment, and in particular to an automatic telescopic material dust suppression and guiding device. Background Technology

[0002] After iron ore beneficiation, the waste rock will be further processed. The production line process is as follows: the waste rock is fed to the jaw crusher by a vibrating feeder. After initial crushing, the waste rock is conveyed to the cone crusher by a belt conveyor for further crushing. Then it is conveyed to the vibrating screen by a belt conveyor for initial screening. Then it is conveyed to the impact crusher by a belt conveyor for crushing. After crushing, it is screened by a multi-stage vibrating screen. The screened stones, stone powder and other products are conveyed to the corresponding areas for storage by the corresponding belt conveyors.

[0003] However, stone processing has an environmental impact, mainly including dust and noise. Currently, there are five main measures taken: First, the production workshop is built in a shed; second, the jaw crusher is installed below ground level; third, an external bag filter is installed, and dust collection ports are set at the discharge ports of the crusher, vibrating screen, and belt conveyor transfer points, and appropriate sealing is adopted. After dust collection, it is transported to the environmental dust collector through pipelines; fourth, water spraying is used to suppress dust at the entrance of the jaw crusher and at the end of the conveyor belts of each product; fifth, secondary sheds are built and sealed at the product discharge port and storage area.

[0004] The existing technology has at least the following problems: even if water is sprayed to suppress dust at the product unloading port and storage area, the dust concentration inside the shed will still be relatively high. The main reason is that during the belt conveyor process, the center distance of the material drop point is large, which causes a large amount of dust to be generated when the material is unloaded and spread to the surrounding area, thus polluting the air. The high dust concentration poses a health hazard to the personnel working there. Utility Model Content

[0005] This invention addresses the shortcomings of existing technologies by developing an automatic telescopic material dust suppression and guiding device. This invention can shorten the center distance of the material drop point and suppress dust, effectively improving the stone processing effect.

[0006] The technical solution of this utility model to solve the technical problem is as follows: an automatic telescopic material dust suppression and guiding device, including a support platform, a winch above the support platform, a guiding pipe below the support platform, a feed inlet on one side of the guiding pipe, a telescopic pipe at the bottom of the guiding pipe, the telescopic pipe including several sets of telescopic joints arranged sequentially from the inside to the outside, a water spray pipe at the bottom of the outermost telescopic joint, and the winch connected to the top of the outermost telescopic joint by a steel wire rope.

[0007] As an optimization, an inner limiting plate is provided on the inner side of the top of the expansion joint, and an outer limiting plate is provided on the outer side of the bottom of the expansion joint. The inner and outer limiting plates of two adjacent sets of expansion joints cooperate with each other. By setting the inner and outer limiting plates, the separation of the upper and lower sets of expansion joints can be prevented.

[0008] As an optimization, an outer baffle is provided on the top outer side of the expansion joint. By setting the outer baffle, the upper expansion joint can be lifted when the lower expansion joint is raised.

[0009] As an optimization, the winch includes a motor, a reducer, a first drum, a second drum, and a third drum. The output end of the motor is connected to the input end of the reducer, and the output end of the reducer is connected to one end of the first drum. The first drum is connected to the second drum via a transmission device, and the second drum is connected to the third drum via a transmission device. By setting up the motor, reducer, and transmission device, the first, second, and third drums can be driven to rotate and move up and down synchronously.

[0010] As an optimization, both ends of the first and second drums are equipped with rope reels. One end of the wire rope is connected to the rope reel, and the other end of the wire rope passes through the support platform and connects to the top of the outermost expansion joint. By setting four sets of rope reels, each can hold one set of wire rope, and the four sets of wire ropes can stably raise and lower the expansion joint.

[0011] As an optimization, the third drum is equipped with a tube coil, on which a water supply pipe is mounted. One end of the water supply pipe passes through the support platform and connects to the spray pipe, while the other end is fixedly installed inside the third drum. The other end of the water supply pipe has a swivel joint located on the outside of the third drum. The tube coil allows for the storage of the water supply pipe; the water supply pipe provides a water source for the spray pipe; and the swivel joint ensures that the water supply pipe is supplied with water without affecting its rotation with the third drum.

[0012] As an optimization, the water spray pipe is circular, with its inner side connected to the outermost expansion joint via a support rod. Several sets of nozzles are evenly distributed at the bottom of the water spray pipe. The support rod supports the water spray pipe, expanding its dust suppression range.

[0013] Compared with the prior art, the present invention has the following beneficial effects: By setting up a support platform, a winch, guide pipe, and telescopic pipe can be hoisted to the roof. The winch and wire rope allow for adjustment of the telescopic pipe's length, enabling it to be adjusted according to the stone's stacking height and maintaining sufficient distance between the telescopic pipe and the top of the stone pile. The guide pipe and feed inlet receive stones from the belt conveyor, allowing them to fall vertically and accumulate, shortening the center distance of the drop point. The telescopic pipe, working in conjunction with the guide pipe, ensures vertical stone accumulation while also collecting dust, reducing dust dispersion. The length of the telescopic pipe can be adjusted as the stone pile rises. A water spray pipe suppresses dust between the telescopic pipe and the stone pile. This invention effectively shortens the center distance of the drop point and suppresses dust, significantly improving the stone processing efficiency. Attached Figure Description

[0019] To clearly illustrate the technical features of this solution, the present invention will be described in detail below through specific implementation methods and in conjunction with the accompanying drawings.

[0020] Example 1 Figures 1 to 4 As one embodiment of this utility model, such as Figures 1 to 4As shown, an automatic telescopic material dust suppression and guiding device includes a support platform 1, a winch 2 above the support platform 1, a guide pipe 3 below the support platform 1, a feed inlet 4 on one side of the guide pipe 3, a telescopic pipe at the bottom of the guide pipe 3, and the telescopic pipe includes several sets of telescopic joints 5 arranged sequentially from the inside to the outside. A water spray pipe 6 is provided at the bottom of the outermost telescopic joint 5. The winch 2 is connected to the top of the outermost telescopic joint 5 by a steel wire rope 7.

[0021] By setting up a support platform 1, a winch 2, a guide pipe 3, and a telescopic pipe can be hoisted to the roof. By setting up the winch 2 and the wire rope 7, the length of the telescopic pipe can be adjusted so that it can be adjusted according to the height of the stone pile, maintaining a sufficient distance between the telescopic pipe and the top of the stone pile. By setting up the guide pipe 3 and the feed inlet 4, stones delivered by the belt conveyor can be received, allowing the stones to fall vertically and accumulate, shortening the center distance of the drop point. By setting up the telescopic pipe, it can work with the guide pipe 3 to allow the stones to fall vertically and accumulate, while also collecting dust and reducing dust emissions. The length of the telescopic pipe can be adjusted as the stone pile rises. By setting up a water spray pipe 6, water can be sprayed to suppress dust between the telescopic pipe and the stone pile.

[0022] An inner limiting plate 8 is provided on the inner side of the top of the telescopic joint 5, and an outer limiting plate 9 is provided on the outer side of the bottom of the telescopic joint 5. The outer limiting plate 9 of the inner telescopic joint 5 cooperates with the inner limiting plate 8 of the outer telescopic joint 5. By setting the inner limiting plate 8 and the outer limiting plate 9, the upper and lower sets of telescopic joints 5 can be prevented from disengaging.

[0023] An outer baffle 10 is provided on the top outer side of the telescopic joint 5, and the outer baffle 10 of the inner telescopic joint 5 is located above the inner limiting plate 8 of the outer telescopic joint 5. By providing the outer baffle 10, the upper telescopic joint 5 can be lifted when the lower telescopic joint 5 is raised.

[0024] The winch 2 includes a brake, a motor 11, a reducer 12, a first drum 13, a second drum 14, and a third drum 15, all mounted on a support platform 1. The output end of the motor 11 is connected to the input end of the reducer 12, and the output end of the reducer 12 is connected to one end of the first drum 13. The first drum 13, the second drum 14, and the third drum 15 are arranged parallel to each other. The first drum 13 is connected to the second drum 14 via a transmission device, and the second drum 14 is connected to the third drum 15 via a transmission device. Each of the first drum 13, the second drum 14, and the third drum 15 is equipped with a brake. By configuring the motor 11, the reducer 12, and the transmission device, the first drum 13, the second drum 14, and the third drum 15 can be driven to rotate and move up and down synchronously.

[0025] Both ends of the first drum 13 and the second drum 14 are equipped with rope reels 16. One end of the wire rope 7 is connected to the rope reel 16, and the other end of the wire rope 7 passes through the support platform 1 and is connected to the top of the outermost telescopic joint 5. By setting four sets of rope reels 16, each set of wire rope 7 can be stored, and the four sets of wire rope 7 can stably raise and lower the telescopic joint 5.

[0026] The third drum 15 is equipped with a tube coil 17, on which a water supply pipe 18 is mounted. The water supply pipe 18 is a PVC steel wire pipe. One end of the water supply pipe 18 passes through the support platform 1 and connects to the spray pipe 6. The other end of the water supply pipe 18 is fixedly installed inside the third drum 15, and a rotary joint 19 is provided at the other end of the water supply pipe 18. The rotary joint 19 is located on the outside of the third drum 15. By setting up the tube coil 17, the water supply pipe 18 can be housed; by setting up the water supply pipe 18, a water source can be provided to the spray pipe 6; by setting up the rotary joint 19, a water source can be provided to the water supply pipe 18 without affecting the rotation of the water supply pipe 18 with the third drum 15.

[0027] The water spray pipe 6 is circular, and its inner side is connected to the outermost telescopic joint 5 via a support rod 20. Several sets of nozzles are evenly arranged at the bottom of the water spray pipe 6. By setting the support rod 20, the water spray pipe 6 can be supported, thus expanding its dust suppression range.

[0028] In use, the support platform 1 is hoisted onto the roof of the storage area. The unloading end of the belt conveyor is aligned with the inlet 4. The telescopic pipe is in the extended state, with the inner telescopic joint 5 on top and the outer telescopic joint 5 on the bottom. The outermost telescopic joint 5 is located at the bottom, with a gap between it and the ground. The outer limiting plate 9 of the inner telescopic joint 5 abuts against the inner limiting plate 8 of the adjacent outer telescopic joint 5, which not only prevents disengagement but also reduces dust escape. The other end of the water pipe 18... One end is connected to the outlet of the water pump via a rotary joint 19, and the inlet of the water pump is connected to the water source via an inlet pipe. During material feeding, the belt conveyor feeds the product into the guide pipe 3 through the feed inlet 4. The product falls along the guide pipe 3, passes through the telescopic pipe, and lands on the ground. At the same time, the water pump pumps clean water from the water source sequentially through the inlet pipe, rotary joint, and water delivery pipe 18 into the spray pipe 6. The nozzles spray water around the circumference of the telescopic joint 5. When dust diffuses outward through the gap, it is absorbed by the water. Fog suppression and dust reduction: Workers can start the winch 2 according to the height of the stacked products. The brakes on the first drum 13, second drum 14, and third drum 15 are released, and the motor 11 starts. The motor 11 drives the first drum 13 to rotate via the reducer 12. The first drum 13 drives the second drum 14 to rotate synchronously via the transmission device. The first drum 13 and second drum 14 simultaneously drive the four sets of rope reels 16 to retract the wire rope 7, lifting the outermost telescopic joint 5. The second drum 14 drives the third drum 15 to rotate synchronously via the transmission device. The third drum 15 drives the pipe reel 17 to retract the water pipe 18, adapting to changes in the height of the telescopic joint 5. As the lower telescopic joint 5 rises, the telescopic pipe gradually shortens. When the inner limit plate 8 of the lower telescopic joint 5 abuts against the outer baffle 10 of the upper telescopic joint 5, the wire rope 7 can simultaneously lift the upper telescopic joint 5, thereby lifting multiple telescopic joints 5 and further shortening the length of the telescopic pipe to adapt to changes in the height of the stacked products.
