Description

Technical Field

[0001] This utility model relates to the technical field of dust removal devices in mines, specifically a mobile dust removal device for open-pit mines. Background Technology

[0002] During the mining process, a large amount of dust is generated. Dust not only harms miners who work directly, causing respiratory diseases such as pneumoconiosis, chronic bronchitis, and emphysema, but it can also irritate the eyes, skin, and mucous membranes, causing discomfort such as conjunctivitis and dermatitis. Moreover, dust from open-pit mines is one of the important sources of air pollutants. Therefore, dust removal is necessary to both protect the health of workers and the environment.

[0003] Currently, dust suppression is achieved through water spraying, which is a relatively simple method. It is inconvenient for dust suppression in small areas. Moreover, water spraying consumes a large amount of water, and prolonged spraying can lead to the accumulation of polluted water on the ground. Furthermore, some water pumps in existing spraying systems require priming before starting up quickly, which can be time-consuming. Utility Model Content

It has the advantages of reducing water waste and enabling rapid water intake for spraying. It solves the problems of current dust suppression methods that rely on water spraying, which are relatively simple and inconvenient for small areas. Furthermore, water spraying consumes a large amount of water, and prolonged spraying can lead to water accumulation on the ground and the formation of new polluted water. In addition, existing spraying solutions often require water intake for some water pumps to start quickly, which can be time-consuming.

[0008] The processing area is equipped with a filter element for filtering dust, and the first partition is provided with a connecting hole located below the filter element for connecting the processing area and the water storage area.

[0009] The dust collector is equipped with a multi-functional channel on the outside of the processing area, which connects the inside and outside of the processing area and is located above the filter element. The dust collector is also connected to a flow guiding mechanism that affects the air pressure state of the processing area. The inner top wall of the processing area is equipped with a dust-suppressing component to suppress the incoming dust.

[0010] Based on the above technical solution, the present invention can be further improved as follows.

[0011] Furthermore, the spraying component consists of a spraying unit and a rotating unit that rotates the spraying unit, and the spraying end of the spraying unit is divergent.

[0012] Furthermore, the spraying unit includes a main spray pipe that is rotatably connected to the dust collector and extends to both ends of the water storage area and forms a seal at the connection with the dust collector. One end of the main spray pipe located outside the water storage area is connected to a spray pipe. A high-pressure nozzle is provided on the outside of the spray pipe. The spraying unit also includes a first spray pump that is fixed to the inner wall of the dust collector and whose liquid outlet end is connected to the main spray pipe in a rotatable and sealed manner.

[0013] Furthermore, the rotating unit includes a drive motor fixed to the inner wall of the dust collector. A transmission ring is fixedly provided on the outer side of the output shaft of the drive motor and on the outer side of the main nozzle. The two transmission rings are connected by a transmission belt.

[0014] Furthermore, the inner wall of the dust collection box is fixed with a protective sleeve that wraps around the first spray pump and the drive motor by fasteners. The main spray pipe passes through the protective sleeve, and a support sleeve that forms a seal and supports the main spray pipe is fixedly installed on the inner wall of the protective sleeve.

[0015] Furthermore, the dust suppression component includes a second spray pump fixed inside the protective sleeve. The input end of the second spray pump is connected to a water suction pipe extending to the bottom wall of the water storage area, and the output end of the second spray pump is connected to a water supply pipe extending to the treatment area. The end of the water supply pipe is connected to a spray frame located in the treatment area.

[0016] Furthermore, the multifunctional channel includes a channel tube, an intermittent sealing frame, a misaligned sealing frame, and a linear actuator for driving the misaligned sealing frame to move.

Detailed Implementation

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] Please see Figure 1-4 This utility model provides a mobile dust removal device for open-pit mines, including a dust removal box 1 with a movable component at the bottom. The inner wall of the dust removal box 1 is fixed with a first partition 2 that divides the interior into two independent spaces. The two independent spaces are a processing area and a water storage area. The water storage area is provided with a spray component that extends to the outside and is in a radiating shape.

[0029] In particular, the mobile mechanism can directly use existing water trucks. When using a water truck solution, the water tank carried by the water truck can be replaced with a dust collection box 1. The mobile mechanism can also be a tracked transport vehicle, with the truck bed replaced with a dust collection box 1.

[0030] For the treatment area and the water storage area, a replenishment pipe should be installed outside the water storage area to facilitate the replenishment of the liquid inside. At the same time, a liquid level sensor and an LED warning light can be installed to effectively remind users of the current liquid level status.

[0031] The processing area is equipped with a filter element for filtering dust. The first partition 2 is provided with a connecting hole located below the filter element to connect the processing area and the water storage area.

[0032] In particular, a one-way valve can be installed at the connecting hole to restrict the flow of fluid, allowing it to flow only from the treatment area to the storage area. This allows the filtered liquid to effectively flow through the one-way valve to the storage area for later use.

[0033] The dust collector 1 is provided with a multi-functional channel 6 that connects the inside and outside of the processing area and is located above the filter element. The dust collector 1 is also connected to a flow guiding mechanism 7 that affects the air pressure state of the processing area. The inner top wall of the processing area is provided with a dust-suppressing component 8 that performs dust suppression treatment on the incoming dust.

[0034] Specifically, a programmable controller should be installed on the outside of the dust collection box 1 to enable the flow guiding mechanism 7, dust collection component 8, spraying component and other electrical control equipment to achieve linkage and control effects.

[0035] The spraying component consists of a spraying unit 3 and a rotating unit 4 that rotates the spraying unit 3. The spraying end of the spraying unit 3 is radiating.

[0036] In this embodiment, the spray unit 3 includes a main spray pipe 31 that is rotatably connected to the dust collector 1 and extends to the inner and outer sides of the water storage area respectively, and forms a seal at the connection with the dust collector 1. One end of the main spray pipe 31 located outside the water storage area is connected to a spray pipe 32. A high-pressure nozzle 33 is provided on the outside of the spray pipe 32. The spray unit 3 also includes a first spray pump 34 that is fixed to the inner wall of the dust collector 1 and whose liquid outlet end is connected to the main spray pipe 31 in a rotatable sealing manner.

[0037] With the above settings, during normal operation, the first spray pump 34 is started and pumps the liquid in the water storage area into the spray pipe 32, and sprays it out through the high-pressure nozzle 33, thereby achieving the spraying of the liquid inside the water storage area.

[0038] In this embodiment, the rotating unit 4 includes a drive motor 41 fixed to the inner wall of the dust collection box 1. A transmission ring 42 is fixedly provided on the outer side of the output shaft of the drive motor 41 and the outer side of the main nozzle 31. The two transmission rings 42 are connected by a transmission belt 43.

[0039] With the above configuration, during the spraying process, the drive motor 41 can be started, which drives the main spray pipe 31 to start rotating through the transmission ring 42 and the transmission belt 43, thereby driving the spray pipe 32 to perform rotating spraying. At the same time, due to the connection between the main spray pipe 31 and the first spray pump 34, its rotation is not affected.

[0040] Specifically, in the above implementation, the transmission ring 42 and the transmission belt 43 can provide a transmission effect for the sprocket and chain, and can also provide a transmission effect for the toothed pulley and toothed belt.

[0041] In this embodiment, the inner wall of the dust collection box 1 is fixed with a protective sleeve 5 that wraps around the first spray pump 34 and the drive motor 41 by fasteners. The main spray pipe 31 passes through the protective sleeve, and the inner wall of the protective sleeve 5 is fixed with a support sleeve 51 that forms a seal and supports the main spray pipe 31.

[0042] The protective sleeve is connected by threaded fasteners, which makes it detachable. At the same time, the support sleeve 51 should be equipped with a bearing to support the main nozzle 31, and the bearing connection should be clearance fit to ensure that disassembly is not affected.

[0043] In this embodiment, the dust suppression component 8 includes a second spray pump 81 fixed inside the protective sleeve 5. The input end of the second spray pump is connected to a suction pipe 82 extending to the bottom wall of the water storage area. The output end of the second spray pump 81 is connected to a water supply pipe 83 extending to the treatment area. The end of the water supply pipe 83 is connected to a spray rack 84 located in the treatment area.

[0044] When the dust suppression component 8 using the above scheme is in use, the second spray pump 81 usually pumps the liquid into the water supply pipe 83 and sprays it out through the spray frame 84, thereby suppressing dust at the spray point by means of liquid adsorption.

[0045] In particular, the spray nozzles on the outside of the spray frame 84 are atomizing nozzles, which can make the liquid atomized and better adsorb dust.

[0046] In this embodiment, the multifunctional channel 6 includes a channel tube 61, an intermittent sealing frame 62, an offset sealing frame 63, and a linear pusher 64 for driving the offset sealing frame to move. The intermittent sealing frame 62 is fixed to the inner side of the channel tube 61 and abuts against the offset sealing frame 63. The interior of both the intermittent sealing frame 62 and the offset sealing frame 63 is provided with intermittent holes that switch between intermittent and overlapping states under the influence of the linear pusher 64. The linear pusher 64 is fixedly connected to the channel tube 61 on the outside and its telescopic end is fixedly connected to the offset sealing frame 63.

[0047] The flow guiding mechanism 7 consists of a flow guiding pipe and a flow guiding fan, and the flow guiding fan and the linear pusher 64 are linked together.

[0048] The multi-functional channel with the above configuration can be closed and opened by the position of the linear pusher 64. When open, the two staggered holes of the misaligned sealing frame 63 and the spaced sealing frame 62 are aligned by the push of the linear pusher 64, which is the open state. When closed, the linear pusher 64 pushes the channel back to the staggered state, which switches it to the closed state.

[0049] Meanwhile, the airflow direction of the guide fan is related to whether the multi-functional channel 6 is open or closed. When the multi-functional channel 6 is closed, the airflow direction of the guide fan is towards the processing area, while when the multi-functional channel 6 is open, the airflow direction of the guide fan is towards the outside of the processing area.

[0050] In this embodiment, the filter element consists of a grid and a filter layer covering its top surface, and the side of the filter element away from the water storage area is inclined downward.

[0051] In particular, the filter layer can be made of multiple layers of gauze directly covering or bonded together. Liquids adsorbed with dust can be effectively recycled by passing through the filter layer during the falling process.

[0052] In this embodiment, the dust collector 1 has a clearance hole on its exterior, with the bottom of the hole flush with the top of the side of the filter element away from the water storage area, and a sealing block is provided at the clearance hole.

[0053] This setup allows for the effective discharge of accumulated sludge.

[0054] In particular, the top of the dust collection box 1 can be designed with an opening in the processing area and sealed with a cover plate to facilitate internal maintenance and cleaning.

[0055] In this embodiment, the inner bottom wall of the dust collector 1 is provided with a guide frame located in the processing area and whose end abuts against the first partition 2. The outside of the dust collector 1 is connected to an outlet pipe whose bottom is flush with the top of the side of the guide frame away from the water storage area.

[0056] Working principle:

[0057] During the overall use, in the conventional spray dust suppression process, the first spray pump 34 drives the liquid inside the water storage area, causing it to be sprayed out through the spray pipe 32 and the high-pressure nozzle 33, thereby adsorbing and suppressing dust in the environment. At the same time, during the spraying process, the drive motor 41 can be started to drive the main spray pipe 31 to rotate through the transmission ring 42 and the transmission belt 43, thereby driving the spray end to start rotating, so as to achieve a larger area of ​​spray dust suppression effect.

[0058] Meanwhile, during the above-mentioned use, the linear pusher 64 can be activated to make the misaligned hole form a misaligned state, ensuring that the multi-functional channel 6 is switched to the closed state. At this time, the flow guiding mechanism 7 is activated, which can push the air towards the treatment area. At this time, the air pressure inside the treatment area increases, which in turn increases the pressure of the water storage area connected to it. Through the pressure, the water can be effectively sent to the first spray pump 34, which can effectively realize the high-speed start of the spraying process, while reducing the load of the first spray pump 34.

[0059] When the water storage is low, the dust suppression scheme of spraying through the spray unit 3 can be abandoned. Instead, the linear pusher 64 is controlled to make the misaligned holes overlap, ensuring that the multi-functional channel 6 is switched to the open state. At this time, the flow guiding mechanism 7 is activated to drive air through the inside of the treatment area. In this case, the second spray pump 81 can be activated to pump the liquid into the spray frame 84 through the suction pipe 82 and the delivery pipe 83 and atomize it. The sprayed atomized water vapor adsorbs the dust and falls to the filter element to start filtration. The filtered water can then return to the water storage area through the one-way valve to form a cycle, thereby achieving the effect of saving water resources.
