Description

Technical Field

[0001] This invention relates to the field of underground dust removal technology, specifically to underground dust removal equipment and methods. Background Technology

[0002] Underground dust removal equipment is specifically designed for use in underground mining environments. Its main function is to remove dust from the air in mines. During underground mining and excavation operations, a large amount of dust is generated. This dust not only affects the visibility of underground workers and reduces work efficiency, but more seriously, long-term inhalation of this dust can lead to serious occupational diseases such as pneumoconiosis, posing a significant threat to workers' health.

[0003] In existing technologies, while existing underground dust removal equipment can continuously filter and remove dust generated during underground mining and excavation operations through the combination of filters and water, it lacks the function of dewatering the tracked filter screens that are washed with water to remove surface dust. If a large amount of water remains on the tracked filter screen, its humidity will increase, making it easier for dust to adhere to its surface during subsequent dust removal processes. This can lead to clogging of the filter screen's pores, reducing airflow and thus affecting its filtration efficiency. Ultimately, this reduces both the effectiveness and efficiency of the underground dust removal equipment.

[0004] Therefore, underground dust removal equipment and methods are proposed to solve the problems mentioned above. Summary of the Invention

[0005] The purpose of this invention is to provide underground dust removal equipment and methods to solve the problem mentioned in the background art that existing underground dust removal equipment does not have the function of dewatering the tracked filter screen that removes surface dust by washing with water. That is, if a lot of water remains on the tracked filter screen, it will increase the humidity of the tracked filter screen, which will make it easier for dust to adhere to its surface when the tracked filter screen is cleaned again. This may lead to blockage of the pores of the tracked filter screen, reduce the airflow through the tracked filter screen, and thus affect the filtration efficiency of the tracked filter screen. This reduces both the effectiveness and efficiency of the underground dust removal equipment.

A tracked filter screen is rotatably connected between the outer surfaces of the multiple transmission rods. The tracked filter screen is located between the four rectangular holes. Two transmission rollers are rotatably connected between the front and rear surfaces of the inner wall of the box.

[0011] Preferably, each of the drive rollers has its two ends movably penetrating the front and rear surfaces of the inner wall of the housing, respectively. The tracked filter screen is located between the outer surfaces of the two drive rollers, and the concave block is located inside the tracked filter screen.

[0016] The method for using underground dust removal equipment includes the following steps:

[0017] S1. When it is necessary to remove dust generated during mine operations, first use one of the sealing plates and the corresponding material hole to inject water into the bottom of the inner wall of the box. Then, use the controller, fan, ventilation pipe and tracked filter to draw the air inside the mine into the ventilation pipe and filter it.

[0018] S2. Next, the controller, motor, two gears, four rectangular holes, bearings, multiple transmission rods and two transmission rollers are used to drive the tracked filter screen. Then, the controller, fan, filter screen, hose, diversion pipe, one-way valve and aerator are used to stir the water stored inside the box and clean the dust attached to the surface of the tracked filter screen that has entered the water.

[0019] S3. At the same time, the gas blown out by the fan outlet, the gas collection shell, the air supply pipe, the first connecting cover and the second connecting cover are used to deliver the gas to the outlet of the second connecting cover.

Then, the water cleaned from the surface of the tracked filter screen is discharged from the inside of the box by the cooperation of the first vent and the second vent.

[0020] Compared with the prior art, the beneficial effects of the present invention are:

[0021] 1. This invention, by setting a water removal mechanism, can remove water from the tracked filter screen whose surface dust is removed by washing with water. This ensures that when the tracked filter screen filters the air inside the mine again, the pores of the tracked filter screen will not become clogged, thereby ensuring the filtration effect of the tracked filter screen. This improves both the use effect and efficiency of the underground dust removal equipment. When the tracked filter screen is washed by the water stored inside the box and its surface dust is removed, and it is driven towards the concave block, the gas blown out by the fan outlet, the gas collection shell, the gas delivery pipe, the first connecting cover and the second connecting cover are used to deliver the gas to the outlet of the second connecting cover.

[0022] 2. The present invention then utilizes the gas blown from the second connecting cover outlet, the diverter plate, the concave block and the vent hole to blow away the water remaining on the surface of the tracked filter screen. Then, by utilizing the cooperation of the first vent hole and the second vent hole, the water cleaned from the surface of the tracked filter screen can be discharged from the inside of the box.

[0023] 3. By setting up a dust removal mechanism, this invention can remove dust generated during mine operations. When dust removal is required, water can be injected into the bottom of the inner wall of the box by using one of the sealing plates and the corresponding material hole. Then, by using the controller, fan, ventilation pipe and tracked filter, the air inside the mine can be drawn into the ventilation pipe and filtered.

[0024] 4. The present invention then utilizes a controller, a motor, two gears, four rectangular holes, bearings, multiple transmission rods, and two transmission rollers to enable the tracked filter screen to perform transmission operations. Subsequently, by utilizing the controller, a blower, a filter screen pre-installed on the blower, a hose, a diversion pipe, a one-way valve, and an aerator, the water stored inside the tank can be agitated.

[0035] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0036] Example 1: Please refer to Figures 1-3 and Figures 5-8 As shown, the present invention provides a technical solution: an underground dust removal device, including a dust removal mechanism 1, and a water removal mechanism 2 is provided on the dust removal mechanism 1;

[0037] The water removal mechanism 2 includes an air-gathering shell 201, a mounting hole 203, a first air outlet 209, and a second air outlet 210. An air supply pipe 202 is installed at the air outlet end of the air-gathering shell 201. A first connecting cover 207 is movably fitted inside the mounting hole 203. A second connecting cover 208 is fixed to the air inlet end of the first connecting cover 207. A concave block 204 is fixed to the air outlet end of the first connecting cover 207. Ventilation holes 205 are provided on both sides of the inner wall of the concave block 204. A diverter plate 206 is fixed inside the concave block 204. The second connecting cover 208 is movably fitted inside the mounting hole 203. The diverter end of the diverter plate 206 is located at the center of the air outlet of the first connecting cover 207. The air inlet of the 8 is installed with the air outlet of the air supply pipe 202. The vent 205, the first air outlet 209, and the second air outlet 210 are at the same height. The first air outlet 209 is opened on the inner wall surface of the housing 101 near the top. The second air outlet 210 is opened on one side of the inner wall of the housing 101 near the top. The mounting hole 203 is opened on the inner wall surface of the housing 101 near the top. The air outlet of the fan 119 is installed with the air inlet of the air collection shell 201. The outer surfaces of the multiple transmission rods 107 are connected by a tracked filter 108. The air outlet of the ventilation pipe 105 is equipped with a fan 119. The fan 119 is electrically connected to the controller 112.

[0038] In this embodiment, when the tracked filter 108 is washed by the water stored inside the housing 101 and its surface dust is removed, and it is driven towards the concave block 204, the air outlet of the fan 119, activated by the controller 112, blows out a large amount of gas. The gas blown out from the air outlet of the fan 119 directly enters the interior of the gas-gathering shell 201, then is transported to the interior of the air supply pipe 202, then to the interior of the second connecting cover 208, then to the interior of the first connecting cover 207, and finally blown out from the air outlet of the first connecting cover 207. When the gas blows out from the air outlet of the first connecting cover 207, under the action of the diverter plate 206, the gas entering the concave block 204 is diverted. The gas in the chamber is split into two streams, which are then blown onto the surface of the tracked filter 108 through the cooperation of two vents 205. At this time, the water remaining on the surface of the tracked filter 108 will be directly carried away by the rapidly flowing air. Then, with the cooperation of the first vent 209 and the second vent 210, it will be discharged from the inside of the housing 101. When the dehydrated tracked filter 108 filters the dust entering the ventilation pipe 105 again, the pores of the tracked filter 108 will not be blocked, thus ensuring the airflow through the tracked filter 108 and ensuring the filtration effect of the tracked filter 108. This improves both the use effect and the efficiency of the underground dust removal equipment.

[0039] Example 2: According to Figures 1-5, Figure 7 and Figure 8 As shown, the dust removal mechanism 1 includes a housing 101. A first air outlet 209 is located on the inner wall surface of the housing 101 near the top. A second air outlet 210 is located on one side of the inner wall of the housing 101 near the top. A mounting hole 203 is located on the inner wall surface of the housing 101 near the top. Two symmetrical support plates 102 are fixed to the bottom of the housing 101. A mounting plate 103 is fixed to the surface of one of the support plates 102 near the bottom. A fan 104 is mounted on the top of the mounting plate 103, and a filter screen is installed at the air inlet of the fan 104. A ventilation pipe 105 is fixedly inserted through the side of the housing 101 near the fan 104, and the air outlet of the ventilation pipe 105 is fixedly inserted through the inner wall of the housing 101. On one side, the bottom of the concave block 204 is fixed to the outer wall of the ventilation pipe 105. The front and rear surfaces of the ventilation pipe 105 are fixed to the inner wall of the box 101 on the front and rear surfaces, respectively. Rectangular holes 106 are provided at the top and bottom of the inner wall of the ventilation pipe 105. Multiple transmission rods 107 are rotatably connected between the front and rear surfaces of the inner wall of the box 101 via bearings. Tracked filter screens 108 are driven between the outer surfaces of the multiple transmission rods 107. The tracked filter screens 108 are located between the four rectangular holes 106. Two transmission rollers 109 are rotatably connected between the front and rear surfaces of the inner wall of the box 101. Each transmission roller 109... The two ends of the 9 respectively move through the front and rear surfaces of the inner wall of the housing 101. The tracked filter screen 108 is located between the outer surfaces of the two drive rollers 109. The concave block 204 is located inside the tracked filter screen 108. A controller 112 is installed on the front surface of the housing 101, and a motor 111 is installed on the rear surface of the housing 101. Gears 110 are fixedly sleeved on the ends of the two drive rollers 109 near the motor 111, and the teeth of the two gears 110 mesh. The output end of the motor 111 is installed with one of the drive rollers 109 near the motor 111. The fan 104 and the motor 111 are both electrically connected to the controller 112. Two material holes 113 are opened on the front surface of the housing 101. All internal components are equipped with sealing plates 114. Aerators 115 are installed at the bottom of the inner wall of the housing 101. The three air inlets of the aerators 115 are movably connected through the bottom of the inner wall of the housing 101. One-way valves 116 are installed at the three air inlets of the aerators 115. A diversion pipe 117 is installed between the air inlets of the three one-way valves 116. The air inlet of the diversion pipe 117 is movably connected through one side of one of the support plates 102. A hose 118 is installed at the air inlet of the diversion pipe 117. The air outlet of the blower 104 is connected to the air inlet of the hose 118. A fan 119 is installed at the air outlet of the ventilation pipe 105. The fan 119 is electrically connected to the controller 112. The air outlet of the fan 119 is connected to the air inlet of the air-gathering shell 201.

[0040] In this embodiment, when dust removal is required during mine operations, the dust removal equipment is first moved into the mine. Then, the controller 112 is connected to an external power supply. Next, one of the sealing plates 114 is removed, and an appropriate amount of water is injected into the housing 101. The sealing plate 114 is then reinstalled in its initial position. Finally, the controller 112 is used to start the fan 119, motor 111, and blower 104. The started fan 119, in conjunction with the ventilation duct 105, draws air from inside the mine into the ventilation duct 105. As the air enters the ventilation duct 105, it passes through the tracked filter 108 and... When the fan 119 delivers air towards the intake end, the tracked filter 108 filters out dust particles mixed in the air passing through it, trapping them on its surface. Simultaneously, the starting motor 111 drives the connected drive roller 109 to rotate. This rotating drive roller 109, in turn, drives another drive roller 109 to rotate through the cooperation of two gears 110. These two opposing drive rollers 109, with the cooperation of four rectangular holes 106, bearings, and multiple drive rods 107, propel the tracked filter 108. At this time, the dust-laden tracked filter 108 moves towards the bottom of the inner wall of the housing 101. The clean tracked filter 108 enters the ventilation duct 105. Simultaneously, the air intake of the activated fan 104, in conjunction with the pre-installed filter, filters the air from inside the mine before drawing it in. This air is then delivered to the hose 118, then to the diversion pipe 117, and subsequently to each one-way valve 116. It then enters the aerator 115 and is ejected from each nozzle of the aerator 115. The ejected air agitates the water stored inside the housing 101. When the tracked filter 108, containing dust, enters the water, the constantly agitated water will... The dust adhering to the surface of 108 is cleaned off, and the cleaned-off dust falls into the water. Then, the dust-removed part of the tracked filter 108 will come out of the water. Then, with the cooperation of two rotating drive rollers 109, it will continue to move towards the concave block 204. At the same time, when the tracked filter 108 passes between the outer surfaces of the two drive rollers 109, the two drive rollers 109 will remove most of the water on the tracked filter 108. Meanwhile, the air continuously injected into the housing 101 will pass directly through the inside of one of the rectangular holes 106 and enter the inside of the ventilation pipe 105, and then flow together with the air entering the ventilation pipe 105.

[0041] The overall effect and working principle of the mechanism are as follows: When dust removal is required during mine operations, the dust removal equipment is first moved into the mine. Then, the controller 112 is connected to an external power supply. Next, one of the sealing plates 114 is removed, and an appropriate amount of water is injected into the housing 101. Then, the sealing plate 114 is reinstalled in its initial position. After that, the controller 112 is used to start the fan 119, motor 111, and blower 104. The fan 119, in conjunction with the ventilation pipe 105, draws air from inside the mine into the ventilation pipe 105. When the air entering the ventilation pipe 105 passes through the tracked filter 108 and is transported towards the air intake of the fan 119, the tracked filter... Under the action of the filter screen 108, dust mixed in the air passing through the tracked filter screen 108 can be filtered and retained on its surface. At the same time, the started motor 111 will drive the connected transmission roller 109 to rotate. The rotating transmission roller 109, in turn, drives another transmission roller 109 to rotate under the cooperation of two gears 110. At this time, the two transmission rollers 109 rotating in opposite directions, in cooperation with four rectangular holes 106, bearings and multiple transmission rods 107, will drive the tracked filter screen 108 to perform transmission operation. At this time, the tracked filter screen 108 with dust will move towards the bottom of the inner wall of the housing 101, while the clean tracked filter screen 108 will enter the interior of the ventilation pipe 105. Meanwhile, the air inlet of the started fan 104 will filter the pre-installed filter. With the help of the mesh, the air inside the mine is first filtered and then drawn into the mesh, then transported to the inside of the hose 118, then to the inside of the diversion pipe 117, then diverted to the inside of each one-way valve 116, then into the inside of the aerator 115, and then sprayed out from each jet end of the aerator 115. The sprayed gas, in conjunction with the agitation, stirs the water stored inside the box 101. When the dust-laden tracked filter 108 enters the water, the constantly agitated water cleans off the dust adhering to the surface of the tracked filter 108. The cleaned-off dust falls into the water, and then the dust-removed part of the tracked filter 108 comes out of the water. Then, with the cooperation of two rotating drive rollers 109, it continues to move towards the concave block 20. As the tracked filter 108 moves in direction 4, and passes between the outer surfaces of the two drive rollers 109, the two drive rollers 109 remove most of the water from the tracked filter 108. Meanwhile, the air continuously injected into the housing 101 passes directly through one of the rectangular holes 106 and enters the ventilation pipe 105, flowing along with the air entering the ventilation pipe 105. Simultaneously, as the tracked filter 108 moves towards the concave block 204, the exhaust end of the activated fan 119 blows out a large amount of gas. This gas then directly enters the air-collecting shell 201, is then transported to the air supply pipe 202, and subsequently to the second connecting cover 208.The gas is then transported to the inside of the first connecting cover 207, and then blown out from the air outlet of the first connecting cover 207. When the gas is blown out from the air outlet of the first connecting cover 207, the gas entering the concave block 204 can be divided into two streams under the action of the diverter plate 206. Then, with the cooperation of the two vents 205, they are blown onto the surface of the tracked filter screen 108 respectively. At this time, the water remaining on the surface of the tracked filter screen 108 will be directly carried away by the fast-flowing air. Then, with the cooperation of the first air outlet 209 and the second air outlet 210, it will be discharged from the inside of the housing 101. When the dehydrated tracked filter screen 108 filters the dust entering the ventilation pipe 105 again, the pores of the tracked filter screen 108 will not be blocked, thus ensuring the airflow through the tracked filter screen 108 and ensuring the filtration effect of the tracked filter screen 108. This improves the use effect and efficiency of the underground dust removal equipment. ,

[0042] Among them, the size of one of the four rectangular holes 106 is larger than the size of the other three rectangular holes 106. The function of one of the rectangular holes 106 is to facilitate the movement of the dust attached to the surface of the tracked filter 108 from the inside of the ventilation pipe 105 and towards the bottom of the inner wall of the box 101.

[0043] Among them, the blower 104, the tracked filter 108, the motor 111, the controller 112 (PLC controller), the aerator 115, the one-way valve 116 and the fan 119 are all existing technologies, and their working principles are all publicly available technologies. Their models can be selected according to the actual situation, and will not be explained in detail here.

[0044] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
