Description

Technical Field

[0001] The invention relates to a wet dust collector, in particular to a wet dust collector for coal mines which is applied in the technical field of coal mine dust removal. Background Art

[0002] The tunneling face is one of the main dust-producing points in coal mines. With the continuous improvement of the mechanization of coal mining, the widespread use of high-efficiency and high-power tunneling machines, the mining intensity of mines is getting higher and higher, and the dust generation of the comprehensive tunneling face has increased sharply. There are problems such as large dust generation and high concentration, which seriously affect the health of workers and threaten the safe production of mines. Dust removal by dust collector is one of the efficient dust prevention measures for the tunneling face. At present, the dust collectors used at home and abroad can be divided into four categories according to the different dust particle capture mechanisms: mechanical dust collectors, filter dust collectors, wet dust collectors, and electrostatic dust collectors. Compared with other dust collectors, wet dust collectors have high dust removal efficiency, and can also reduce temperature, increase humidity, and handle flammable, explosive, and harmful and toxic gases.

[0003] The invention patent with publication number CN109488362B discloses a wet dust collector for coal mines, which includes a controller arranged on a mine tunnel; a No. 1 electromagnetic water valve and a water outlet pipe are arranged in the middle of the first spray plate; the water outlet pipe is connected to the water tank, and the lower end of the water outlet pipe faces the center of the liquid collecting tank; the No. 1 electromagnetic water valve is arranged on the water outlet pipe, and the No. 1 electromagnetic water valve is electrically connected to the controller through a wire; the liquid collecting tank includes a tank body, a filter plate hinged at one end to the end of the tank body, a No. 1 elastic airbag located at the lower end of the other end of the filter plate, a No. 1 air pipe and an elastic rope; the No. 1 electromagnetic water valve is electrically connected to the controller through a wire; the filter plate includes a filter cloth and a plate body for fixing the filter cloth; the end of the filter cloth is arranged at one end of the No. 1 air pipe, and the pipe mouth of the No. 1 air pipe is along the filter plate surface toward the bottom of the filter plate with one end of the filter plate with the No. 1 elastic airbag, and the other end of the No. 1 air pipe is connected to the No. 1 elastic airbag; it can reduce the jamming problem of the equipment during operation by clearing the equipment itself.

The dust gas in the coal mine enters the venturi tube 1 through the air inlet 2, and in the process of circulation, the water vapor generated by the water inlet pipe 9 is sucked into the inner cavity of the venturi tube 1, so that the dust and the water mist are fully mixed, which is convenient for subsequent dust removal operations. The movement of the adjustment block 15 is controlled by the telescopic member 16 to control the distance between the block and the roar of the venturi tube 1 and adjust the flow rate of the gas in the venturi tube 1. The mud entering the sewage chamber 21 can enter the sewage pipe 7 through the flushing pipe 24 and be discharged externally by controlling the switch of the solenoid valve 28.

[0020] It is worth mentioning that the cyclone mechanism includes a driving member 18 installed at the lower part of the inner cavity of the venturi tube 1, a cyclone mesh disk 17 installed circumferentially along the output shaft of the driving member 18, and a pressure sensor 25 installed between the cyclone mesh disk 17 and the output shaft of the driving member 18. The cyclone mesh disk 17 is controlled to rotate at a high speed by the driving member 18. When the mixture of dust and water mist enters the bottom of the venturi tube 1, it will be intercepted by the high-speed rotating cyclone mesh disk 17 and thrown to the inner wall of the venturi tube 1 by the action of centrifugal force, and flow to the sewage chamber 21 along the inner wall of the venturi tube 1. The air can pass through the high-speed rotating cyclone mesh disk 17 normally, thereby intercepting the dust and water mist in the air and improving the dust removal and filtration efficiency.

[0021] In addition, an exhaust port 4 is connected to the top of the purification chamber 3, a drying filter layer 11 is installed in the middle of the inner cavity of the purification chamber 3, a washing liquid is arranged at the bottom of the inner cavity of the purification chamber 3, a washing plate 30 is arranged in the washing liquid of the purification chamber 3, the inner cavity of the washing plate 30 is connected to a transfer ring 19 through a connecting pipe 20, the transfer ring 19 is placed below the cyclone mesh plate 17 in the inner cavity of the venturi tube 1, an air inlet is opened on the transfer ring 19, a fan can be installed at the exhaust port 4, the gas enters through the air inlet 2 of the venturi tube 1, and is discharged through the exhaust port 4 on the purification chamber 3, the gas after being processed by the cyclone mechanism in the venturi tube 1 enters the connecting pipe 20 through the transfer ring 19, the gas enters through the connecting pipe 20 and is discharged by the washing plate 30, the discharged gas is washed with water by the washing liquid in the purification chamber 3, so as to further improve the dust removal and filtering effect, the washed gas is filtered through the drying filter layer 11 and discharged, so as to reduce the humidity of the gas.

[0022] In this embodiment, the dust removal intelligent controller 5 is installed on the purification chamber 3. The dust removal intelligent controller 5 is provided with a dust treatment module, a cyclone treatment module and a sludge treatment module. The dust treatment module is electrically connected to the cyclone treatment module, the dust concentration sensor 12 and the telescopic member 16 respectively. The cyclone treatment module is electrically connected to the driving member 18 and the pressure sensor 25 respectively. The sludge treatment module is electrically connected to the liquid level sensor 23 and the solenoid valve 28. The gas containing dust in the coal mine enters the venturi tube 1 through the air inlet 2, and the dust concentration sensor 12 detects the dust in the gas. The dust content is detected and the detection data is sent to the dust treatment module. The dust treatment module controls the telescopic member 16 to work according to the dust content. The telescopic member 16 controls the adjustment block 15 to move and adjust the gas intake amount, and the dust treatment efficiency is adaptively adjusted. The water mist containing dust is intercepted by the high-speed rotating cyclone mesh disk 17 and thrown to the inner wall of the venturi tube 1. After long-term use, more sludge will gradually remain on the cyclone mesh disk 17, and the gravity of the cyclone mesh disk 17 will gradually increase. With the action of centrifugal force, the pressure sensor 25 detects the increase of tension data, and the pressure sensor 25 will The detected tension data is sent to the cyclone processing module, and the cyclone processing module compares the received tension data with the tension threshold (the cyclone processing module is preset with the tension data detected by the pressure sensor 25 when the residual sludge on the cyclone mesh disk 17 is the largest at the same speed). When the tension threshold is reached, the cyclone processing module sends a cleaning signal to the dust processing module, and the dust processing module controls the telescopic part 16 to work so that the adjustment block 15 moves downward, so that the water mist discharged through the water inlet pipe 9 can flush the cyclone mesh disk 17 in the form of large particles, and the water inlet pipe 9 can be adjusted synchronously. The flow rate is increased by the water flow to flush the cyclone mesh disk 17, which is convenient for automatically detecting the sludge contamination of the cyclone mesh disk 17, and automatically cleaning and flushing the cyclone mesh disk 17, thereby increasing the service life of the equipment and reducing the maintenance cycle; the sludge will accumulate in the sewage chamber 21, and when the liquid level sensor 23 detects the thickness of the sludge and sends it to the sludge processing module, the sludge processing module detects that the sludge thickness reaches a preset height, and controls the solenoid valve 28 on the sewage pipe 7 to open for sewage discharge, automatically controls sewage discharge, reduces manual maintenance, and realizes the automation and intelligent operation of the dust collector.

[0023] Also, see Figure 1 , Figure 5 and Figure 6A diffuser 14 opening downward is provided on the water inlet pipe 19, a switch pipe 10 is inserted in the middle of the water inlet pipe 19, and a diffuser hole 27 and a flushing hole 26 corresponding to the diffuser 14 are respectively provided on the switch pipe 10, and the diameter of the diffuser hole 27 is smaller than the diameter of the flushing hole 26. A telescopic member 28 whose output end is connected to the switch pipe 10 is installed on one side of the venturi tube 1, and the swirl treatment module is electrically connected to the telescopic member 28. The water entering the water inlet pipe 19 is discharged downward through the diffuser 14. In this process, the water will enter the inner cavity of the switch pipe 10 and pass through the diffuser hole 27 or the flushing hole 26 opened on the switch pipe 10. The water is discharged through the washing hole 26 and enters the inner cavity of the venturi tube 1 through the diffuser 14. During normal dust treatment, the water entering the switching tube 10 will enter the diffuser 14 through the diffuser hole 27, and the amount of water discharged through the washing hole 26 is relatively large. When the cyclone treatment module sends a cleaning signal to the dust treatment module, the telescopic part 28 will be controlled to work. The telescopic part 28 drives the switching tube 10 to move so that the washing hole 26 is connected to the diffuser 14. The water enters the inner cavity of the venturi tube 1 through the washing hole 26, thereby increasing the amount of water entering the inner cavity of the venturi tube 1, so as to better wash the cyclone mesh plate 17.

[0024] Also, see Figure 5 and Figure 6 A hot water pipe 6 is connected to the output end of the water inlet pipe 9, and a hot water pump is externally connected to the hot water pipe 6 for inputting hot water into the water inlet pipe 9 through the hot water pipe 6. The cyclone treatment module is electrically connected to the hot water pump. When the cyclone treatment module sends a cleaning signal to the dust treatment module, it controls the hot water pump to work. The hot water pump inputs hot water into the water inlet pipe 9 through the hot water pipe 6. The hot water enters the inner cavity of the venturi tube 1 through the flushing hole 26. The hot water can better clean the sludge on the cyclone mesh disk 17, thereby improving the cleaning efficiency of the cyclone mesh disk 17.

[0025] Preferably, see Figure 2 , Figure 4 and Figure 7 The transfer ring 19 is arranged around the outer ring of the driving member 18, and the air inlet opening on the transfer ring 19 is downward, so that the gas can enter the purification chamber 3 through the transfer ring 19 and reduce the sludge from falling into the air inlet opening of the transfer ring 19. The cyclone mesh disk 17 is provided with a plurality of barrier strips installed along its radial direction, so that the high-speed rotating barrier strips can intercept the dust-water mist mixture, and the gas can flow smoothly, thereby improving the filtering and dust removal effect. The inner cavity of the purification chamber 3 is located below the dry filter layer 11 and is provided with a baffle filter layer 33. The baffle filter layer 33 is provided with a bent channel. When the gas flows through the baffle filter layer 33 in the bent channel, the water vapor will be gradually intercepted and fall into the water washing liquid at the bottom, thereby further reducing the humidity of the gas.

[0026] The second implementation method: Figure 2 , Figure 7 and Figure 8 It is shown that, different from the first embodiment, the wet dust collector also includes a flushing mechanism, which includes a water inlet pipe 2 13 installed at the bottom of the purification chamber 3, a solenoid valve 2 29 installed on the water inlet pipe 2 13, the flushing pipe 24 is connected to the bottom of the inner cavity of the purification chamber 3, and a solenoid valve 3 32 is installed at the connection between the flushing pipe 24 and the inner cavity of the purification chamber 3. The impurities filtered by the water washing liquid in the purification chamber 3 will gradually settle at the bottom of the water washing liquid. When it is detected that the sludge content in the sewage chamber 21 is relatively high, the water washing liquid is flushed into the sewage chamber 21 by controlling the solenoid valve 3 32 to open, and the sludge can also be discharged at the bottom of the water washing liquid into the sewage chamber 21 for treatment together. By controlling the solenoid valve 3 32 to close and the solenoid valve 1 28 to open, the muddy water is discharged through the sewage pipe 7 to improve the sewage discharge efficiency.

[0027] It is worth mentioning that a liquid level sensor 2 31 is installed on the inner cavity side wall of the purification chamber 3, and a liquid level sensor 3 22 is installed on the inner cavity side wall of the venturi tube 1. The liquid level sensor 3 22 is located above the liquid level sensor 1 23. A flushing module is also provided on the dust removal intelligent controller 5. The flushing module is electrically connected to the sludge treatment module, the liquid level sensor 3 22, the liquid level sensor 2 31, the solenoid valve 3 32 and the solenoid valve 2 29 respectively. When the liquid level sensor 1 23 detects the thickness of the sludge and sends it to the sludge treatment module, the sludge treatment module detects that the sludge thickness reaches a preset height, the sludge treatment module will send a flushing signal to the flushing module. At this time, the flushing module controls the solenoid valve 3 32 to open, and the washing liquid and sludge enter the sewage chamber 21 to flush and dilute the sludge. The liquid level sensor 3 22 will detect the sludge. The sewage content in the water chamber 21 is sent to the flushing module. When the flushing module detects that the sewage content reaches the sewage threshold (the flushing module is preset with the maximum value of the sewage content in the sewage chamber 21), the flushing module controls the solenoid valve three 32 to close and the solenoid valve one 28 to open, and discharges the muddy water through the sewage pipe 7 to improve the sewage discharge efficiency. At the same time, the flushing module controls the solenoid valve two 29 to open, and the replenished washing liquid enters the inner cavity of the purification chamber 3 through the water inlet pipe two 13, and the liquid level sensor two 31 detects the content of the washing liquid in the purification chamber 3 and sends it to the flushing module. When the flushing module detects that the washing liquid content reaches the preset value, it controls the solenoid valve two 29 to close, thereby automatically replenishing the washing liquid flowing out during flushing, so that the dust collector can operate normally, realize uninterrupted dust removal operation, and realize the automatic and intelligent operation of the dust collector.

[0028] In addition, the water inlet pipe 13 is connected to the bottom of the inner cavity of the purification chamber 3. During flushing, the flushing liquid injected through the water inlet pipe 13 can be used to flush the sludge at the bottom of the inner cavity of the purification chamber 3. The bottom of the inner cavity of the purification chamber 3 and the bottom of the sewage cavity 21 are both inclined toward the flushing pipe 24, which is convenient for concentrating the sludge to be discharged at the flushing pipe 24, thereby improving the sewage discharge efficiency.

[0029] In view of current practical needs, the above-mentioned implementation mode adopted in this application is not limited to the scope of protection. Various changes made within the knowledge scope of technical personnel in this field without departing from the concept of this application still fall within the scope of protection of the present invention.
