Description

Technical Field

[0001] The invention relates to the technical field of mine dust removal, in particular to a mine wet dust collector. Background Art

[0002] Wet dust removal is a method of purifying the gas by fully contacting water with dust-containing gas to wash away dust particles. This dust removal method has high efficiency, simple dust collector structure, low cost, small footprint, easy operation and maintenance, and is particularly suitable for handling high-temperature, high-humidity, flammable and explosive dust-containing gases. In addition, some gaseous pollutants can be removed while removing dust. In mineral mining and tunnel footage, a large amount of dust will be generated due to underground operations, especially when excavating in coal mines. During the operation, in order to ensure the normal operation, the dust must be collected and filtered to remove the excess dust contained in the air. In existing dust removal operations, wet dust removal is mainly used for processing.

[0003] Existing wet dust removal devices, such as Chinese patent application CN107185342A, add a coarse filter screen at the entrance of the air inlet pipe. During the process of suction through the negative pressure blower, large particles that can settle by gravity are automatically filtered out, and only small particles or dust are allowed to enter, so as to prevent large particles from entering and settling to cause damage to the equipment. During the suction process, the airflow is cut off in a curtain-like manner through the periodic circulation of the paddle and the baffle, and then the incoming airflow is humidified through the spray duct. The humidified airflow is sent to the next stage together with the gas and liquid flow through the guiding and intercepting action of the curtain flow fan plate. In the movable curtain humidifier, on the one hand, the moistened gas is transported through the driving action of the curtain jet plate, and on the other hand, it is further humidified through the atomization of the jet atomizer gun. In this process, strong humidification is performed to moisten all the dust in the air and gradually form larger particles for dust flocculation. After the large particles are flocculated, some of the moistened fine dust is intercepted after passing through the adsorption filter plate and the adsorption curtain inside the sewage discharger. Under the influence of continuous moisture, it flows downward in strands and is discharged through the sewage outlet, thereby improving the practicality and applicability of the device.

[0004] However, there are still the following problems: although the sewage generated in the wet dust collector will be discharged, some of the dust will precipitate in the sewage in the wet dust collector, resulting in some sludge being unable to be discharged, which may easily cause operational failures of the wet dust collector.

DETAILED DESCRIPTION

[0020] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0021] As introduced in the background technology, there are deficiencies in the prior art. In order to solve the above technical problems, this application proposes a wet dust collector for mining.

[0022] In a typical implementation of the present application, Figure 1 , Fig.10As shown, a wet dust collector for mining includes a base 1, a dust removal mechanism 2 arranged on the base 1, and a sewage discharge mechanism 3 arranged on the dust removal mechanism 2. The dust removal mechanism 2 includes a pipe body 21 and a water bath box 26. The pipe body 21 is fixedly mounted on the base 1, and the water bath box 26 is arranged in the pipe body 21. The sewage discharge mechanism 3 includes a sewage discharge end 32, an impeller 37, and a toggle blade 314. The sewage discharge end 32 is provided on the pipe body 21, and the impeller 37 is arranged in the sewage discharge end 32. A plurality of toggle blades 314 are arranged between the water bath box 26 and the sewage discharge end 32, and the toggle blades 314 are located in the pipe body 21. When the dust collector is working, the sewage discharge end 32 discharges the sewage generated in the water bath 26. When deposited sludge is generated between the water bath 26 and the sewage discharge end 32, the sewage flow rate of the sewage discharge end 32 is reduced, so that the rotation speed of the impeller 37 is reduced. The water bath 26 is fully opened to allow the internal water to be completely discharged to the sewage discharge end 32. The impact of the water pushes the deposited sludge to flow toward the sewage discharge end 32. The rotation speed of the impeller 37 increases and drives the paddle 314 to rotate. The paddle 314 paddles the deposited sludge between the sewage discharge end 32 and the water bath 26.

[0023] When using the present invention: First, water is injected into the water bath 26, and then the dust collector is started to suck the dust into the pipe body 21, so that the dust is concentrated and sent into the water bath 26, so that the dust passes into the water in the water bath 26 and then emerges from the water, so that the water bath 26 performs water bath dust removal on the dust, and then the gas after the water bath dust removal will also undergo water drop dust removal and water film dust removal, and the dust-removed sewage will flow in the pipe body 21 to the sewage discharge end 32, so that the sewage is discharged from the pipe body 21 through the sewage discharge end 32, and when the sewage flows through the sewage discharge end 32, the sewage impact force The impeller 37 is rotated, and when the sediment sludge is generated between the water bath 26 and the sewage discharge end 32, the sewage flow rate of the sewage discharge end 32 is reduced, so that the rotation speed of the impeller 37 is reduced. At this time, the water bath 26 is fully opened to discharge the internal water completely to the sewage discharge end 32. The impact of the water pushes the sediment sludge to flow to the sewage discharge end 32. The speed of the impeller 37 increases and drives the shifting blade 314 to rotate. The shifting blade 314 shifts the sediment sludge between the sewage discharge end 32 and the water bath 26 to better discharge the sediment sludge in the pipe body 21. When deposited sludge is generated between the water bath 26 and the sewage discharge end 32, the sewage flow at the sewage discharge end 32 is reduced, thereby reducing the rotation speed of the impeller 37. The water bath 26 is fully opened to allow the internal water to be completely discharged to the sewage discharge end 32. The impact of the water pushes the deposited sludge to flow toward the sewage discharge end 32, and the rotation speed of the impeller 37 increases and drives the moving blades 314 to rotate. The moving blades 314 move the deposited sludge between the sewage discharge end 32 and the water bath 26 to better discharge the deposited sludge. This effectively solves the problem that although the sewage generated in the wet dust collector will be discharged, some of the dust will be precipitated in the sewage in the wet dust collector, resulting in part of the sludge being unable to be discharged, which may easily cause operating failures of the wet dust collector. This avoids the inability to discharge the deposited sludge in the dust collector, thereby ensuring stable operation of the dust collector.

[0026] The motor 22 is started, and the motor 22 drives the two-stage impeller 23 to rotate. At the same time, the two-stage impeller 23 realizes reverse rotation through the reversing gear set 24 to perform co-directional suction, and the blocking grid 25 blocks large objects that may exist when sucking dust.

[0030] The gas after water bath dust removal is discharged to the bottom of the water drop nozzle rack 210, and the water supply pipe 211 supplies water to the water drop nozzle rack 210, so that the water drop nozzle rack 210 sprays water to perform water drop dust removal on the gas after water bath dust removal.

[0031] Further, such as Figure 2 , Figure 6 As shown, a second air collecting hood 212 is fixedly installed in the tube body 21, and the second air collecting hood 212 is sealed with the tube body 21.

[0032] Among them, the gas after water droplet dust removal is discharged from the air outlet of the second wind collecting hood 212 to enter the partition box 213, and the water supply pipe 211 simultaneously supplies water to the down-cut water nozzle 216, so that the down-cut water nozzle 216 sprays water on the wall of the partition box 213, so that a water film is formed on the wall of the partition box 213, and the gas after water droplet dust removal enters the partition box 213 and is guided by the spiral guide plate 214, so that the gas after water droplet dust removal is spirally transported in the partition box 213, and the water film in the partition box 213 is used to perform water film dust removal on the gas after water droplet dust removal, and the gas after water film dust removal is discharged from the exhaust port 215 and discharged from the pipe body 21 at the same time. At this time, the discharged gas is clean gas, so that a multi-stage treatment of water bath dust removal, water droplet dust removal and water film dust removal is formed for the dust, which effectively improves the quality of dust removal.

[0033] Further, such as Figure 1 , Figure 7As shown, the sewage discharge mechanism 3 also includes a sewage discharge channel 31, which is fixedly installed at the inner bottom end of the tube body 21, one end of the sewage discharge channel 31 is connected to the water bath box 26, one end of the sewage discharge channel 31 is communicated with the drain port 29, the sewage discharge channel 31 passes through the second air collecting hood 212, the sewage discharge channel 31 passes through the partition box 213, the sewage discharge channel 31 passes through the spiral guide plate 214, and a sewage discharge end 32 is provided at the bottom of the other end of the tube body 21, and the sewage discharge end 32 is adjacent to the other end of the sewage discharge channel 31.

[0034] Furthermore, since the dust collector keeps running all the time, the sewage in the sewage discharge channel 31 is always uninterrupted, so the connection formed by the sewage discharge channel 31 to various areas in the pipe body 21 does not affect the operation of the dust collector.

[0035] Further, such as Figure 7-Figure 9 As shown, an electrically controlled lifting valve 33 is fixedly installed on the side wall of the water bath 26, and the electrically controlled lifting valve 33 is opposite to the drain outlet 29.

[0039] Part of the sewage generated during the dust removal process will first remain in the water bath 26, and the rest will flow from the sewage channel 31 to the sewage end 32, so that the sewage will flow out from the sewage end 32, and the sewage will drive the impeller 37 on the shaft 36 to rotate, the impeller 37 drives the chain 310 to rotate, the chain 310 drives the positioning shaft 39 to rotate, the positioning shaft 39 drives the bevel gear 311 to rotate, the bevel gear 311 drives the linkage rod 312 to rotate, and the linkage rod 312 drives the bevel gear 315 The bevel gear 315 drives the auxiliary shaft 313 to rotate, and the auxiliary shaft 313 drives the toggle blade 314 to rotate. When a large amount of sediment sludge is generated in the sewage discharge channel 31, the sludge will cause the water level to rise, thereby reducing the flow of sewage to the sewage discharge end 32, thereby causing the speed of the impeller 37 to decrease. When the resistance of the sediment sludge, water and other objects to the toggle blade 314 is sufficient to overcome the rotational force brought to the toggle blade 314 by the impeller 37, the impeller 37 and the toggle blade 314 are 14 all stop rotating, at this time the detector 38 detects that the impeller 37 stops rotating, thereby judging that at this time there is a lot of deposited sludge in the sewage chute 31, the detector 38 controls the electric control lifting valve 33 to open, and at the same time the detector 38 controls the electric control valve 35 to open, so that water is injected into the water bath 26, and the sewage in the water bath 26 is discharged into the sewage chute 31, because a large amount of sewage is flushed out, the impact of the sewage impulsively moves the deposited sludge, so as to flush the deposited sludge into the sewage discharge end 32, as the deposited sludge gradually flows into the sewage discharge end 32, the discharge volume of sewage gradually increases, so that the impact of the sewage and the sludge drives the impeller 37 to rotate again, and at the same time the impeller 37 drives the toggle blade 314 to rotate, so that the toggle blade 314 to toggle the deposited sludge, so that the sludge is better discharged with the sewage, and after executing the preset time, the detector 38 controls the electric control lifting valve 33 to close, and after water is re-injected into the water bath 26, the detector 38 controls the electric control valve 35 to close.

[0040] Working principle: First, water is injected into the water bath 26, and then the dust collector is started to suck the dust into the pipe body 21, so that the dust is concentrated and sent into the water bath 26, so that the dust passes into the water in the water bath 26 and then emerges from the water, so that the water bath 26 performs water bath dust removal on the dust, and then the gas after the water bath dust removal will also be subjected to water drop dust removal and water film dust removal, and the wastewater after dust removal will flow to the sewage discharge end 32 in the pipe body 21, so that the sewage is discharged from the pipe body 21 through the sewage discharge end 32 When sewage flows through the sewage discharge end 32, the sewage impact force causes the impeller 37 to rotate. When sludge is deposited between the water bath 26 and the sewage discharge end 32, the sewage flow rate of the sewage discharge end 32 is reduced, causing the speed of the impeller 37 to decrease. At this time, the water bath 26 is fully opened to allow the internal water to be completely discharged to the sewage discharge end 32. The impact force of the water pushes the deposited sludge to flow to the sewage discharge end 32, and the speed of the impeller 37 increases and drives the toggle blade 314 to rotate. The toggle blade 314 has an effect on the discharge end 32. The deposited sludge between the sewage end 32 and the water bath 26 is moved to better discharge the deposited sludge in the pipe body 21. When the deposited sludge is generated between the water bath 26 and the sewage end 32, the sewage flow rate of the sewage end 32 is reduced to reduce the rotation speed of the impeller 37. The water bath 26 is fully opened to allow the internal water to be completely discharged to the sewage end 32. The impact of the water pushes the deposited sludge to flow to the sewage end 32. The speed of the impeller 37 increases and drives the shifting blade 314 to rotate. The shifting blade 314 shifts the deposited sludge between the sewage end 32 and the water bath 26 to better discharge the deposited sludge. This effectively solves the problem that although the sewage generated in the wet dust collector will be discharged, some of the dust will be precipitated in the sewage in the wet dust collector, resulting in some sludge being unable to be discharged, which is easy to cause the operation failure of the wet dust collector. This avoids the sludge deposited in the dust collector from being unable to be discharged, and ensures the stable operation of the dust collector. The motor 22 is started, and the motor 22 drives the two-stage impeller 23 to rotate. At the same time, the two-stage impeller 23 realizes reverse rotation through the reversing gear set 24 to perform co-directional air suction, and the blocking grid 25 blocks large objects that may exist when sucking dust. The sucked dust is guided by the first air collecting hood 27, so that the dust is sent from the extended air outlet into the water in the water bath box 26, so that the dust is subjected to water bath dust removal. The gas after water bath dust removal emerges from the water and is sent out from the air outlet port 28, and the sewage can be discharged from the drain port 29; In addition, the gas after the water bath dust removal is discharged to the bottom of the water drop nozzle rack 210, and the water supply pipe 211 supplies water to the water drop nozzle rack 210, so that the water drop nozzle rack 210 sprays water to perform water drop dust removal on the gas after the water bath dust removal. The gas after the water drop dust removal is discharged from the air outlet of the second air collecting hood 212 to enter the partition box 213. The water supply pipe 211 simultaneously supplies water to the down-cutting water spray nozzle 216, so that the down-cutting water spray nozzle 216 sprays water on the wall surface of the partition box 213, so that the wall surface of the partition box 213 forms a water After the gas after the water droplet dust removal enters the partition box 213, it is guided by the spiral guide plate 214, so that the gas after the water droplet dust removal is spirally transmitted in the partition box 213, and the water film in the partition box 213 is used to perform water film dust removal on the gas after the water droplet dust removal. The gas after the water film dust removal is discharged from the exhaust port 215 and the pipe body 21 at the same time. At this time, the discharged gas is clean gas, so as to form a multi-stage treatment of water bath dust removal, water droplet dust removal, and water film dust removal for the dust, which effectively improves the quality of dust removal; At the same time, part of the sewage generated during the dust removal process will first remain in the water bath box 26, and the rest will flow from the sewage discharge channel 31 to the sewage discharge end 32, so that the sewage will flow out from the sewage discharge end 32, and the sewage will drive the impeller 37 on the shaft 36 to rotate, the impeller 37 drives the chain 310 to rotate, the chain 310 drives the positioning shaft 39 to rotate, the positioning shaft 39 drives the bevel gear 311 to rotate, the bevel gear 311 drives the linkage rod 312 to rotate, and the linkage rod 312 drives the bevel gear 315 The bevel gear 315 drives the auxiliary shaft 313 to rotate, and the auxiliary shaft 313 drives the toggle blade 314 to rotate. When a large amount of sediment sludge is generated in the sewage discharge channel 31, the sludge will cause the water level to rise, thereby reducing the flow of sewage to the sewage discharge end 32, thereby causing the speed of the impeller 37 to decrease. When the resistance of the sediment sludge, water and other objects to the toggle blade 314 is sufficient to overcome the rotational force brought to the toggle blade 314 by the impeller 37, the impeller 37 and the toggle blade 314 are 14 all stop rotating, at this time the detector 38 detects that the impeller 37 stops rotating, thereby judging that at this time there is a lot of deposited sludge in the sewage chute 31, the detector 38 controls the electric control lifting valve 33 to open, and at the same time the detector 38 controls the electric control valve 35 to open, so that water is injected into the water bath 26, and the sewage in the water bath 26 is discharged into the sewage chute 31, because a large amount of sewage is flushed out, the impact of the sewage impulsively moves the deposited sludge, so as to flush the deposited sludge into the sewage discharge end 32, as the deposited sludge gradually flows into the sewage discharge end 32, the discharge volume of sewage gradually increases, so that the impact of the sewage and the sludge drives the impeller 37 to rotate again, and at the same time the impeller 37 drives the toggle blade 314 to rotate, so that the toggle blade 314 to toggle the deposited sludge, so that the sludge is better discharged with the sewage, and after executing the preset time, the detector 38 controls the electric control lifting valve 33 to close, and after water is re-injected into the water bath 26, the detector 38 controls the electric control valve 35 to close.
