Description

Technical Field

[0001] This utility model relates to the field of fan technology, and in particular to a wet dust removal fan for mining. Background Technology

[0002] Mining operations involve a large amount of dust, so fans are used to absorb the dusty gases. Traditional wet dust collectors use water vapor to contact the dust, mixing the dust and water to form sludge, which is then removed by a filtration device, thus achieving wet dust removal. However, the wastewater after use is directly discharged, increasing the consumption of water resources.

[0003] The existing technology CN211715369U discloses a wet dust collector for mining, including a support frame, a fan body above the support frame, a motor on one side of the fan body, a rotating shaft on one side of the motor output end, impeller blades on the outside of the rotating shaft, a collector shroud on one side of the fan body, a water tank below the fan body, a water pump on one side of the water tank, water guide pipes on both sides of the water pump, a filter chamber on one side of the water tank, a drain pipe between the filter chamber and the fan body, an air outlet on one side of the fan body, and a sludge discharge pipe on one side of the filter chamber. Through the arrangement of the filter plate, vibrator, and sludge discharge pipe, when wastewater passes through the filter plate, the sludge mixed in the wastewater is filtered out, improving the purity of the water for reuse. The metal filter screen can also filter the gas, removing particulate matter mixed in the gas, thus improving the purity of the gas.

[0004] However, using the above method, a large amount of dust particles will adhere to the surface of the metal filter screen after long-term use. Since the metal filter screen of the existing mine wet dust collector is installed inside the fan cylinder, it is not convenient to clean the dust particles on the metal filter screen, which will cause the metal filter screen to become clogged, thus affecting the absorption effect of dust gas during mine operations. Utility Model Content

[0005] The purpose of this utility model is to provide a wet dust collector for mining, which aims to solve the problem that existing wet dust collectors for mining are not easy to clean dust particles on the metal filter screen, which leads to clogging of the metal filter screen and thus affects the absorption effect of dust gas during mining operations.

[0006] To achieve the above objectives, this utility model provides a wet dust collector for mining, including a base and a dust collection assembly. The dust collection assembly includes a housing, a mounting frame, multiple limiting components, a first filter, a second filter, a sealing component, a spraying component, and an exhaust component.

[0007] The housing and the base are fixedly connected and the housing is located on top of the base.

The first filter is located in the first receiving groove, and the second filter is located in the second receiving groove. The sealing component is arranged on the maintenance opening. The spraying component is arranged on the housing. The exhaust component is arranged on the side of the housing.

[0008] The limiting component includes a torsion spring, a stop bar, and a central shaft; the torsion spring is fixedly connected to the mounting frame and is located inside the mounting frame; the stop bar is fixedly connected to the torsion spring and is located at the end of the torsion spring away from the mounting frame; the central shaft is fixedly connected to the stop bar and rotatably connected to the mounting frame, and is located inside the torsion spring.

[0009] The sealing component includes a cover plate and mounting bolts; the cover plate is located at the top of the maintenance port, and the side of the cover plate near the maintenance port has a protrusion; the mounting bolts are threadedly connected to the cover plate and to the housing, and are located on the side of the cover plate.

[0010] The spraying component includes a water tank, a water pump, a water suction pipe, a flexible hose, and an atomizing nozzle. The water tank is fixedly connected to the base and located on top of the base. The water pump is fixedly connected to the housing and located on the side of the housing. The water suction pipe communicates with the water tank and the water pump, and is located between the water tank and the water pump. The flexible hose communicates with the water pump and is fixedly connected to the cover plate, and is located between the cover plate and the water pump.

[0011] The exhaust component includes a motor and an impeller; the motor is fixedly connected to the housing and located on the side of the housing; the impeller is fixedly connected to the output end of the motor and located inside the housing.

[0012] This utility model discloses a wet dust collector for mining. During mine operations, the blowing component draws dusty gas into the casing through the air inlet, and the spraying component sprays the dusty gas to remove dust. Dust particles are filtered by the first and second filters, and the dust-removed gas passes through the first filter and is discharged from the outlet. When it is necessary to clean the dust particles on the first and second filters, the sealing component is removed from the maintenance port, and then the mounting frame is removed from the maintenance port. Workers can then remove the first and second filters from the mounting frame for cleaning. After the first and second filters are cleaned, the first filter is placed in the first receiving groove, and the second filter is placed in the second receiving groove. The limiting component fixes the positions of the first and second filters. Then, the mounting frame is inserted into the housing through the maintenance port, with the bottom of the mounting frame positioned within the placement groove. The placement groove restricts horizontal movement of the mounting frame. The sealing component is then reinstalled at the maintenance port. This invention facilitates the disassembly and assembly of the first and second filters to clean dust particles from them, preventing clogging and reducing the absorption effect of dust and gas during mine operations. This solves the problem of existing wet dust collectors in mines being unable to clean dust particles from metal filters, leading to clogging and affecting the absorption effect of dust and gas during mine operations.

The aforementioned solution solves the problem that existing wet dust collectors for mining are prone to clogging of metal filter screens due to the inconvenience of cleaning dust particles, which affects the absorption effect of dust and gas during mine operations.

[0024] In this specific embodiment, the housing 102 and the base 101 are fixedly connected and the housing 102 is located on top of the base 101. The housing 102 has an air inlet 110 and an air outlet 111 at both ends, a placement groove 112 at the bottom, and a maintenance opening 113 at the top. The mounting frame 103 is located inside the housing 102, and has a first receiving groove 114 and a second receiving groove 115. Multiple limiting components 104 are respectively disposed on the sides of the mounting frame 103. The first filter 105 is located in the first receiving groove 114, and the second filter 106 is located in the second receiving groove 115. The sealing component 107 is disposed on the maintenance opening 113. The spray component 108 is disposed on the housing 102. The exhaust component 109 is disposed on the side of the housing 102. During mine operations, the blowing component draws dusty gas into the housing 102 through the air inlet 110. The spray component 108 sprays the dusty gas to remove dust. Dust particles are filtered by the first filter screen 105 and the second filter screen 106. The dust-removed gas passes through the first filter screen 105 and is discharged from the air outlet. When it is necessary to clean the dust particles on the first filter screen 105 and the second filter screen 106, the sealing component 107 is removed from the maintenance port 113, and then the mounting frame 103 is removed from the maintenance port 113.

The first filter 105 and the second filter 106 are fixed in position by component 104. Then, the mounting frame 103 is inserted into the housing 102 through the maintenance port 113, with the bottom of the mounting frame 103 positioned in the placement groove 112. The placement groove 112 restricts the horizontal movement of the mounting frame 103. Then, the sealing component 107 is reinstalled at the maintenance port 113. This invention facilitates the disassembly and assembly of the first filter 105 and the second filter 106 to clean dust particles on them, preventing clogging of the first filter 105 and the second filter 106 and reducing the absorption effect of dust gas during mine operations. This solves the problem that existing wet dust collectors for mines are not easy to clean dust particles from metal filter screens, leading to clogging of the metal filter screens and affecting the absorption effect of dust gas during mine operations.

Dust particles are filtered by the first filter screen 105 and the second filter screen 106. After filtration, the water flows back into the water tank 122, and the dust-removed gas passes through the first filter screen 105 and is discharged from the air outlet. When it is necessary to clean the first filter screen 105 and the atomizing nozzle 126, the impeller 127 drives the impeller 128 to rotate, drawing dusty gas into the housing 102 through the air inlet 110. The impeller 127 draws water from the water tank 122 through the water pipe 124 and delivers the water to the atomizing nozzle 126 for spraying and dust removal. When cleaning dust particles on the second filter screen 106, unscrew the mounting bolts 120 from the housing 102, remove the cover plate 119 from the maintenance port 113, and then remove the mounting frame 103 from the maintenance port 113. Next, the operator rotates the baffle 117 away from the first filter screen 105 and the second filter screen 106, and then removes the first filter screen 105 and the second filter screen 106 from the mounting frame 103 for cleaning. After the first filter screen 105 and the second filter screen 106 are cleaned, place the first filter screen 105 in the first receiving groove 1. Within 14, the second filter screen 106 is placed in the second receiving groove 115. The positions of the first filter screen 105 and the second filter screen 106 are fixed using the stop bar 117. Then, the mounting frame 103 is inserted into the housing 102 through the maintenance port 113, with the bottom of the mounting frame 103 positioned within the placement groove 112.
