Description

Technical Field

[0001] The utility model relates to the technical field of open-pit mine belt transport dust removal equipment, in particular to an open-pit mine belt corridor transport dust removal device. Background Art

[0002] In the production process of open-pit mines, after the ore is crushed, it is conveyed by belts to various transfer stations, docks and other areas for dispersion. In recent years, the national infrastructure has risen rapidly, and the demand for sand and gravel aggregates has increased linearly. The important raw material for aggregate production is limestone, also known as limestone. The main component is carbonate rock, sometimes containing dolomite, clay minerals and detrital minerals. It has gray, gray-white, gray-black, yellow, light red, brown-red and other colors, and has a violent chemical reaction with dilute hydrochloric acid.

[0003] At present, in order to actively respond to the national call, a large number of open-pit limestone mines have been developed and utilized, and various corresponding environmental protection problems have followed. Among them, a large amount of ore dust will be generated during the belt transportation of ore. The dust will not only cause harm to human health, but also cause dust pollution to the surrounding ecological environment.

[0004] The existing dust control method generally adopts the method of adding multiple water spray pipes on the side of the belt, and utilizes the adsorption force of water to solve the dust problem in the process of ore transportation. However, by spraying water to reduce dust, the dust is easily formed into a large amount of ore powder blocks that stick to the conveyor belt after being humidified by the water spraying, which is not conducive to subsequent cleaning work. It is not only easy to cause blockage and damage to the conveying equipment, but also shortens the service life and causes a waste of water resources. At the same time, during the transportation process of the ore, due to its large volume and the characteristics of accumulation between ores, the method of dust removal by water spray pipes cannot effectively remove the dust attached to the surface of the ore, and the ore dust removal is not thorough, and the dust removal effect is poor. Utility Model Content

[0005] The utility model provides a method for controlling dust during ore belt transportation without wasting water resources or sacrificing the service life of equipment, and has the advantages of thorough dust removal and good effect.

[0006] In order to solve the above technical problems, the utility model adopts the following technical solutions:

[0011] A discharge pipe is arranged on the outer wall of the other side of the shell, and a discharge transmission belt for discharging materials from the shell is arranged inside the discharge pipe.

[0012] Preferably, one end of the material conveying pipe is connected to the shell, and the other end is provided with a feeding port, and the material conveying transmission belt extends from one end away from the material conveying pipe to the inside of the shell.

At the same time, the dust is absorbed by the dust suction mechanism, which can avoid the problems of damaging the service life of the conveying equipment and wasting water resources caused by traditional water spraying. The ore has the advantages of thorough dust removal and good effect.

In the utility model, when the ore is transported to the cleaning table, on the one hand, the ore is used to generate impact force on the cleaning table, and at the same time, the vibrator is used to generate vibration on the cleaning table. The combination of the above two forces is used to achieve complete removal of dust on the surface of the ore dropped on the cleaning table; at the same time, a baffle is arranged above the cleaning table to prevent small particles of ore from splashing due to elastic force, thereby avoiding damage to the internal equipment.

DETAILED DESCRIPTION

[0029] A preferred embodiment of the present invention is described in detail below in conjunction with the accompanying drawings.

[0030] To achieve the above purpose, the embodiments of the present invention adopt the following technical solutions: Figure 1 , Figure 2 A dust removal device for belt corridor transportation in an open-pit mine includes a shell 10, a conveying pipe 20, a vibration mechanism, a dust suction mechanism and a discharge pipe 60. The conveying pipe is arranged on an outer wall of one side of the shell, and a conveying belt 30 for conveying materials to the shell is arranged in the conveying pipe. The vibration mechanism includes a cleaning table 410 and a vibrator 420. The cleaning table 410 is movably arranged on the inner wall of the shell 10, and the cleaning table is located at the output end of the conveying belt. The vibrator 420 is also arranged inside the shell, and the vibrator is used to drive the cleaning table to vibrate. Furthermore, the dust suction mechanism is arranged on the inner wall of the shell, and the dust suction mechanism is used to absorb dust generated when the vibration mechanism vibrates the material. The pipe is arranged on the outer wall of the other side of the shell, and a discharge conveyor belt 70 for discharging materials from the shell is arranged in the discharge pipe. When in use, the ore enters from the feed pipe and is conveyed to the inside of the shell via the feed conveyor belt. During transportation, the feed pipe can prevent the ore from being blown by the wind and causing dust to fly. The ore conveyed by the feed conveyor belt falls onto the cleaning table. The impact force generated by the fall and the vibration of the vibrator below make the cleaning table descend and rebound, that is, the cleaning table produces a vibration effect to shake off the dust attached to the surface of the ore, and then the dust is absorbed by the dust suction mechanism. The ore after vibration and dust removal then falls into the discharge pipe and is conveyed to the outside of the shell via the discharge conveyor belt, thereby completing the dust removal operation of the ore.

[0031] As a preferred technical solution of this embodiment, the feed pipe is a through pipe, and one end of the feed pipe 20 is connected to the shell 10, and the other end is provided with a feeding port 210. The feed transmission belt 30 extends from one end of the feed pipe to the inside of the shell 10. When in use, ore can be fed into the feed belt from the feeding port, and the ore enters the feed transmission belt along the feed belt and enters the inside of the shell through the feed transmission belt.

[0032] It should be noted that the feed pipe can prevent the dust on the surface of the ore from flying due to the influence of wind when the feed belt transports the ore, thereby causing adverse effects on the surrounding environment; the discharge pipe can shield the discharge belt to prevent the internal dust from flying out of the shell through the opening on the side of the shell; therefore, the cooperation of the feed pipe and the discharge pipe can further improve the dust storage effect of the open-pit mine belt corridor transport dust removal device.

[0033] Reference Figure 3 As a preferred technical solution of this embodiment, a sliding block 430 is provided on the inlet side of the cleaning table 410. The bottom of the sliding block 430 is movably connected to the inner wall of the shell 10 through a spring plate 440. The ore transported by the feeding belt first falls on the sliding block, and the ore is transported into the shell through the sliding block. After the ore separates from the sliding block, it falls on the cleaning table. The impact force generated by the fall causes the spring plate under the sliding block to descend and rebound, and cooperates with the vibration of the vibrator below to transmit the vibration energy to the cleaning table, so that the sliding block continuously moves inside the shell, produces a vibration effect, and shakes off the dust on the surface of the ore.

[0034] Furthermore, a slide groove is provided on the inner wall of the shell 10, and the bottom of the spring plate 440 is connected to the inner wall of the slide groove. Under the impact of the gravity of the ore and the vibration of the vibrator, the cleaning table can make the sliding block move continuously in the slide groove inside the shell, and cooperate with the rebound effect of the spring plate to completely shake off the powder on the surface of the ore.

[0035] Furthermore, in order to improve the vibrating effect of the vibrator on the cleaning table, a folding sleeve 450 is provided at the output end of the vibrator 420, and a support frame 460 is provided at the end of the folding sleeve away from the vibrator, and the support frame 460 is fixedly connected to the cleaning table 410. It should be noted that the support frame 460 is configured to be L-shaped. The vibrator in this embodiment is an industrial component that has a vibration effect. Since it is a prior art, it will not be described here. When in use, the vibration energy generated by the vibrator is transmitted to the cleaning table through the folding sleeve and the support frame, thereby achieving the vibrating effect of the cleaning table, thereby shaking off the dust on the surface of the passing ore.

[0036] Reference Figure 4As a preferred technical solution of this embodiment, the dust suction mechanism includes a dust collector 510 and a dust storage box 520. The dust collector 510 is arranged on the inner wall of the shell 10, and the dust storage box 520 is arranged on the air outlet side of the dust collector. At the same time, an interception net 530 is provided on the side of the dust storage box opposite to the dust collector, and a movable bottom cover 540 is provided at the bottom of the dust storage box. Furthermore, a dust inlet 511 is provided on the side of the dust collector close to the cleaning table. After the powder on the surface of the ore is shaken off, it is sucked into the dust collector through the dust inlet and discharged from the interception net. When the air is discharged, the interception net intercepts the dust particles, and then the dust is dropped into the groove below the dust storage box for storage by gravity. After use, the movable bottom cover can be rotatably connected to the bottom of the dust storage box, the movable bottom cover can be rotated to open, and the dust inside the dust storage box can be dumped out for subsequent cleaning.

[0037] Furthermore, the side wall of the cleaning table 410 is provided with a baffle 470 extending to the top of the cleaning table, and the baffle can prevent small particles of ore from splashing due to elastic force, thereby avoiding damage to the internal equipment.

[0038] Furthermore, the cleaning table 410 is configured to be in a slide shape, and the baffle 470 is disposed in the upper area of ​​the cleaning table opening. The slide-shaped cleaning table facilitates the smooth rolling of the ore transported by the feed belt, thereby shaking off the dust attached to the surface of the ore in combination with the vibration of the vibrator.

[0039] When in use, ore is thrown into the feed port 210 and falls on the sliding block 430 inside the shell 10. The sliding block 430 transports the ore to the inside of the shell. During the transportation, the feed pipe 20 can prevent the ore from being blown by the wind and causing dust to fly. When the sliding block transports the ore to the inside of the shell, the ore falls on the top of the cleaning table 410 after separating from the sliding block. The impact force generated by the fall causes the spring plate 440 under the sliding block to drop and rebound. The baffle 470 can prevent small particles of ore from being splashed by the elastic force. The vibrator 420 below will vibrate through the support The support frame 460 is transmitted to the cleaning table 410, so that the sliding block continuously moves in the slide groove opened inside the shell, and cooperates with the rebound effect of the spring plate to shake off the powder on the surface of the ore. The dust collector 510 sucks the dust through the dust inlet and discharges the air from the interception net 530. When the air is discharged, the interception net intercepts the dust particles, and then the dust is dropped into the groove below the dust storage box 520 by gravity for storage. After use, the movable bottom cover 540 can be rotatably connected to the bottom of the dust storage box 520, and the movable bottom cover can be rotated to open, and the dust inside can be dumped out for subsequent cleaning.

[0040] The above-described embodiments are merely descriptions of preferred embodiments of the present invention, and are not intended to limit the scope of the present invention. Without departing from the design spirit of the present invention, various modifications and improvements made to the technical solutions of the present invention by ordinary technicians in this field should all fall within the protection scope determined by the claims of the present invention.
