Description

Technical Field

[0001] This invention relates to the field of spray device technology, specifically to an automatic backwashing spray device for mining. Background Technology

[0002] Mining environments are complex, especially during underground mining, where issues such as dust, high temperatures, and harmful gases are prominent. Dust hazards arise from drilling, blasting, and transportation processes, which generate large amounts of inhalable particulate matter. Long-term exposure can easily lead to occupational diseases such as silicosis. High temperatures and gas risks are also present, as geothermal and mechanical heat generation during deep well mining can cause high temperatures, and the accumulation of gas can potentially trigger explosions. Dust suppression is also necessary, but traditional water spraying is inefficient. Spraying technology can absorb dust through water mist, improving air quality.

[0003] Early mine spraying devices were mostly fixed or manually controlled, which had obvious defects. High concentrations of dust and impurities easily clogged the nozzles, requiring frequent manual cleaning, which affected the continuity of operations. Fixed installations made it difficult to dynamically adjust the spray range, resulting in dust suppression blind spots. Summary of the Invention

[0004] To achieve the above objectives, the present invention provides the following technical solution: an automatic backwashing spray device for mining, comprising a filter box, an air inlet device fixedly connected to the bottom of the filter box, a box support fixedly connected to the bottom of the filter box on both sides of the air inlet device, rollers fixedly connected to the bottom of the box support, a filter assembly fixedly connected to the inner wall of the filter box, a water inlet connector connected to the side of the filter box, an inlet device fixedly connected to the top of the filter box, an atomizing device connected to the side of the inlet device, and the side of the atomizing device fixedly connected to the side of the filter box;

[0005] The air intake device includes an exhaust turbofan. The output end of the exhaust turbofan is connected to an intake one-way valve. An oblique air inlet is connected to the side of the exhaust turbofan. An intake bracket is fixedly connected to the top of the exhaust turbofan. A filter frame is fixedly connected to the top of the intake bracket. A convex filter screen is fixedly connected to the inner wall of the filter frame. The top of the intake one-way valve is connected to the bottom of the filter housing. The intake bracket penetrates the bottom of the filter housing and is fixedly connected to the bottom of the filter housing. The side of the filter frame is fixedly connected to the inner wall of the filter housing. The exhaust turbofan draws air through the oblique air inlet and into the exhaust turbofan. The fan's interior is vented through an intake one-way valve, which guides air into the inner wall of the filter housing, thus directing the air into the water. This directly mixes dust and other impurities with the water, preventing dust from entering the inlet device. The air passes through the arc-shaped holes, through the bottom of the convex filter screen, and reaches the top of the convex filter screen. Impurities are trapped below the convex filter screen. The convex design of the filter screen increases the contact area, extending its service life and reducing maintenance frequency. The angled air inlet design avoids drawing air from the bottom and sides, thus reducing the probability of dust being drawn out.

[0006] Preferably, the filter assembly includes a filter box, a filter support fixedly connected to the bottom of the inner wall of the filter box, a concave filter screen fixedly connected to the inner wall of the filter support, a filter handle fixedly connected to the inner wall of the filter box, a diverter block fixedly connected to the inner wall of the filter box below the filter handle, an arc-shaped hole opened at the bottom of the filter box, the concave filter screen being positioned below the water inlet connector, the side of the filter box being fixedly connected to the inner wall of the filter housing, and the inner wall of the arc-shaped hole contacting the side of the inlet device.

[0008] Preferably, the atomizing device includes a T-shaped bracket, with a first motor fixedly connected to the top of the T-shaped bracket and the bottom of the T-shaped bracket fixed; an inlet tube is connected, with a dust cover fitted and fixedly connected to the side of the inlet tube, and an atomizing component connected to the bottom of the inlet tube. A backwash component is rotatably connected to the inner wall of the atomizing component, and the side of the inlet tube is connected to the side of the water outlet pipe.

[0009] Preferably, the atomizing component includes a rotary joint, a drive shaft is fixedly connected to the bottom of the inner wall of the rotary joint, a pneumatic fan blade is fixedly connected to the side of the rotary joint, a first guide pipe is connected to the side of the rotary joint located on the side of the pneumatic fan blade, a spray component is fixedly connected to the inner wall of the first guide pipe, the top of the rotary joint is connected to the bottom of the guide pipe, the top of the drive shaft is fixedly connected to the drive shaft of the first motor, and the pneumatic fan blade is located below the dust cover.

[0010] Preferably, the spray assembly includes a spray bracket, a rotating tube rotatably connected to the side of the spray bracket, a first blade sleeved and fixedly connected to one side of the rotating tube, an arc-shaped rotating seat sleeved and fixedly connected to the end of the rotating tube away from the first blade, an arc-shaped guide plate fixedly connected to the side of the arc-shaped rotating seat, and the bottom of the spray bracket fixedly connected to the inner wall of the first guide tube. The water outlet pipe introduces air into the interior of the rotary joint. Air and water enter the interior of the first guide tube through the rotary joint, pass through the side of the first blade, and reach the side of the arc-shaped guide plate. The arc design of the first blade and the arc-shaped guide plate passively generates rotation, driving the rotating tube to rotate along the spray bracket. Air and water are mixed and sprayed out from the gap between the arc-shaped guide plate and the first guide tube, thus performing atomization spraying. The rotation of the arc-shaped rotating seat causes the arc-shaped guide plate and the edge of the first guide tube to rotate relative to each other, thereby reducing the possibility of dust clogging at the spray outlet. The pneumatic fan blades drive the air to flow, thereby expanding the coverage area of ​​the atomized water spray.

[0011] Preferably, the backflush assembly includes a second guide tube, a fixing ring is sleeved and fixedly connected to the side of the second guide tube, a backflush bracket is fixedly connected to the side of the second guide tube away from the fixing ring, a guide box is fixedly connected to the side of the backflush bracket, a backflush nozzle is connected to the side of the guide box, the second guide tube penetrates the inner wall of the rotating tube and is rotatably connected to the inner wall of the rotating tube, and the side of the backflush bracket cooperates with the arc-shaped rotating seat.

[0012] This invention provides an automatic backwashing spray device for mining. It has the following beneficial effects:

[0013] 1. This mine-use automatic backwashing spray device is equipped with an exhaust turbine fan. The exhaust turbine fan drives air through the interior of the inclined air inlet, through the exhaust turbine fan, and through the intake one-way valve. The intake one-way valve guides the air into the inner wall of the filter box, thus sending the air into the water. This directly mixes dust and other impurities with the water, preventing dust from entering the inlet device. The air passes through the bottom of the convex filter screen and reaches the top of the convex filter screen through the filtration effect of the arc-shaped holes. Impurities are left below the convex filter screen. The convex design of the convex filter screen increases the contact area, thereby extending the service life and reducing the frequency of maintenance. The inclined air inlet design avoids air extraction from the bottom and sides, thus reducing the probability of dust being extracted.

[0014] 2. This mine-use automatic backwashing spray device is equipped with a concave filter screen. Water falls on the top of the concave filter screen, thus filtering the water entering the device. Impurities are trapped at the top of the concave filter screen, completing the filtration process. The filter handle is used to remove the entire filter box for easy maintenance and replacement. The diverter block is used to divert the water flow, preventing water from splashing onto the surface and affecting the filtration effect. The concave design of the filter screen increases the contact area between the water and the screen, extending the service life of the filter screen and reducing maintenance frequency. Furthermore, the water introduced by the inlet connector does not fall directly onto the lowest point of the concave filter screen; impurities are concentrated at the lowest point of the screen under gravity, thus preventing filter blockage caused by impurity accumulation.

[0015] 3. This mine-use automatic backwashing spray device is equipped with a water pump. The water pump drives the inlet pipe to pump water. The partition plate inside the inlet pipe separates water and air. Water is drawn through the bottom of the inlet pipe, and air is drawn through the bottom of the air inlet plate, thus mixing the air and water and sending it into the interior of the atomizing device for diffusion. The bottom of the inlet pipe is located between the top of the convex filter screen and the bottom of the concave filter screen, thereby drawing the filtered water and air to achieve the mixing and atomization of air and water for spraying.

[0016] 4. This mine-use automatic backwashing spray device is equipped with a first motor. The drive shaft of the first motor drives the atomizing component to rotate, and the rotation of the atomizing component drives the backwashing component to move, thereby completing the multi-angle spraying of water mist. The inlet pipe introduces water and air. The inclined design of the dust cover reduces the possibility of dust falling into the atomizing component, thereby reducing the possibility of blockage. The T-shaped bracket enhances the support strength through its T-shaped design, thereby enhancing the availability of the equipment. The backwashing component automatically cleans the area around the spray outlet of the atomizing component, thereby preventing blockage.

[0017] 5. This automatic backwashing spray device for mining is equipped with a water outlet pipe that introduces air into the interior of the rotary joint. The air and water enter the interior of the first guide pipe through the rotary joint, pass through the side of the first blade, and reach the side of the arc-shaped guide plate. The arc design of the first blade and the arc-shaped guide plate passively generates rotation, driving the rotary pipe to rotate along the spray support. The air and water are mixed and sprayed out from the gap between the arc-shaped guide plate and the first guide pipe, thus performing atomization spraying. The rotation of the arc-shaped rotating seat causes the edge of the arc-shaped guide plate to rotate relative to the edge of the first guide pipe, thereby reducing the possibility of dust clogging at the spray outlet. The air is driven by the pneumatic fan blades to flow, thereby expanding the coverage area of ​​the atomized water spray.

[0018] 6. This automatic backwashing spray device for mining is equipped with a second guide pipe. Water and air flow through the interior of the second guide pipe. The water passes through the interior of the second guide pipe, through the inner wall of the guide box, and is sprayed out through the backwash nozzle. The backwash nozzle drives the guide box to rotate. The rotation direction of the guide box is opposite to the rotation direction of the arc-shaped guide plate, so that the edge of the arc-shaped rotating seat is automatically backwashed when atomized and sprayed, thereby automatically cleaning and reducing the possibility of blockage during atomization. At the same time, the air and water overflowing from the edge of the guide box pass through the arc of the arc-shaped rotating seat to clean the dust simultaneously, thereby reducing the possibility of blockage.

[0029] 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.

[0030] Please see Figures 1-4 The present invention provides a technical solution: an automatic backwashing spray device for mining, comprising a filter box 1, an air inlet device 2 fixedly connected to the bottom of the filter box 1, a box support 3 fixedly connected to the bottom of the filter box 1 on both sides of the air inlet device 2, rollers 4 fixedly connected to the bottom of the box support 3, a filter assembly 5 fixedly connected to the inner wall of the filter box 1, a water inlet connector 6 connected to the side of the filter box 1, an inlet device 7 fixedly connected to the top of the filter box 1, an atomizing device 8 connected to the side of the inlet device 7, and the side of the atomizing device 8 fixedly connected to the side of the filter box 1.

[0031] The filter housing 1 supports the equipment, the air inlet device 2 filters and introduces the gas, the housing bracket 3 and rollers 4 drive the filter housing 1 to move, thereby facilitating atomization spraying at different locations, the filter assembly 5 filters the water introduced into the inner wall, the water inlet connector 6 introduces external water source, the introduction device 7 introduces water and gas, and the atomization device 8 sprays out water and gas. Under the mixing of air and water, the water and gas are atomized and sprayed out, simultaneously achieving filtration of water and gas, and the components automatically clean the spray points to prevent clogging.

[0032] The air intake device 2 includes an exhaust turbine fan 201. The output end of the exhaust turbine fan 201 is connected to an intake check valve 202. The side of the exhaust turbine fan 201 is connected to an oblique air inlet 203. An intake bracket 204 is fixedly connected to the top of the exhaust turbine fan 201. A filter frame 205 is fixedly connected to the top of the intake bracket 204. A convex filter screen 206 is fixedly connected to the inner wall of the filter frame 205. The top of the intake check valve 202 is connected to the bottom of the filter housing 1. The intake bracket 204 passes through the bottom of the filter housing 1 and is fixedly connected to the bottom of the filter housing 1. The side of the filter frame 205 is fixedly connected to the inner wall of the filter housing 1.

[0033] When the exhaust fan 201 is activated, it draws air through the interior of the angled air inlet 203 and then through the intake check valve 202. The intake check valve 202 guides the air into the inner wall of the filter housing 1, thus delivering the air into the water. This directly mixes dust and other impurities with the water, preventing dust from entering the inlet device 7. The air passes through the arc-shaped holes 506 and through the bottom of the convex filter screen 206 to the top. Impurities are trapped below the convex filter screen 206. The convex design of the convex filter screen 206 increases the contact area, extending its service life and reducing maintenance frequency. The angled air inlet 203 avoids drawing air from the bottom and sides, thus reducing the probability of dust being drawn out.

[0034] The filter assembly 5 includes a filter box 501. A filter support 502 is fixedly connected to the bottom of the inner wall of the filter box 501. A concave filter screen 503 is fixedly connected to the inner wall of the filter support 502. A filter handle 504 is fixedly connected to the inner wall of the filter box 501. A diverter block 505 is fixedly connected to the inner wall of the filter box 501 below the filter handle 504. An arc-shaped hole 506 is opened at the bottom of the filter box 501. The concave filter screen 503 is located below the water inlet connector 6. The side of the filter box 501 is fixedly connected to the inner wall of the filter housing 1. The inner wall of the arc-shaped hole 506 contacts the side of the inlet device 7.

[0035] Water is introduced through the inlet connector 6 and falls on top of the concave filter screen 503, thus filtering the incoming water. Impurities are retained on top of the concave filter screen 503, completing the filtration process. The filter handle 504 is used to remove the entire filter box 501 for easy maintenance and replacement. The diverter block 505 is used to divert the water flow, preventing splashing that could affect the filtration effect. The concave design of the concave filter screen 503 increases the contact area between the water and the screen, extending its service life and reducing maintenance frequency. Furthermore, the water introduced through the inlet connector 6 does not fall directly onto the lowest point of the concave filter screen 503; impurities are concentrated at the lowest point under gravity, preventing filter clogging caused by impurity accumulation.

[0036] Please see Figures 1-6 The present invention provides a technical solution: the inlet device 7 includes a water pump 701, the input end of the water pump 701 is connected to a water inlet pipe 702, the inner wall of the water inlet pipe 702 is fixedly connected to a partition plate 703, the side of the partition plate 703 is fixedly connected to an air inlet plate 704, the output end of the water pump 701 is connected to a water outlet pipe 705, the end of the water outlet pipe 705 away from the water pump 701 is connected to an atomizing device 8, the bottom of the water pump 701 is fixedly connected to the top of the filter box 1, and the side of the water inlet pipe 702 is in contact with the inner wall of the arc-shaped hole 506.

[0037] The water pump 701 is started, which drives the water inlet pipe 702 to pump water. The partition plate 703 inside the water inlet pipe 702 separates water and air. Water is drawn through the bottom of the water inlet pipe 702, and air is drawn through the bottom of the air inlet plate 704, thereby mixing the air and water and sending it into the atomizing device 8 for diffusion. The bottom of the water inlet pipe 702 is located between the top of the convex filter screen 206 and the bottom of the concave filter screen 503, thereby drawing the filtered water and air to achieve the mixing and atomization of air and water.

[0038] The atomizing device 8 includes a T-shaped bracket 801, with a first motor 802 fixedly connected to the top of the T-shaped bracket 801 and the bottom of the T-shaped bracket 801 fixedly connected; an inlet pipe 803 is connected, and a dust cover 804 is sleeved and fixedly connected to the side of the inlet pipe 803; the bottom of the inlet pipe 803 is connected to an atomizing component 805; a backwash component 806 is rotatably connected to the inner wall of the atomizing component 805; the side of the inlet pipe 803 is connected to the side of the water outlet pipe 705; the drive shaft of the first motor 802 is fixedly connected to the bottom of the atomizing component 805; and the side of the T-shaped bracket 801 is fixed to the side of the filter box 1.

[0039] The first motor 802 is started, and its drive shaft drives the atomizing component 805 to rotate. The rotation of the atomizing component 805 drives the backwash component 806 to move, thereby completing the multi-angle spraying of water mist. The inlet pipe 803 introduces water and air. The inclined design of the dust cover 804 reduces the possibility of dust falling into the atomizing component 805, thereby reducing the possibility of clogging. The T-shaped bracket 801 enhances the support strength through its T-shaped design, thereby enhancing the usability of the equipment.

[0042] The water outlet pipe 705 introduces air into the rotary joint 8051. The air and water enter the first guide pipe 8054 through the rotary joint 8051, pass through the side of the first blade 80553, and reach the side of the arc-shaped guide plate 80555. The arc design of the first blade 80553 and the arc-shaped guide plate 80555 passively generates rotation, driving the rotating pipe 80552 to rotate along the spray bracket 80551. The air and water are mixed and sprayed out from the gap between the arc-shaped guide plate 80555 and the first guide pipe 8054, thus atomizing the spray. The rotation of the arc-shaped rotating seat 80554 causes the edge of the arc-shaped guide plate 80555 and the first guide pipe 8054 to rotate relative to each other, thereby reducing the possibility of dust clogging the spray outlet. The air is driven by the pneumatic fan blade 8053 to flow, thereby expanding the coverage of the atomized water spray.

The backwash nozzle 8065 drives the guide box 8064 to rotate. The rotation direction of the guide box 8064 is opposite to the rotation direction of the arc-shaped guide plate 80555. Thus, when the atomized spray is applied, the edge of the arc-shaped rotating seat 80554 is automatically backwashed, thereby automatically cleaning and reducing the possibility of blockage during atomization. At the same time, the air and water overflowing from the edge of the guide box 8064 pass through the arc of the arc-shaped rotating seat 80554 to simultaneously clean the dust, thereby reducing the possibility of blockage.
