Description

TECHNICAL FIELD

[0001] The application belongs to the technical field of dust removal, and particularly relates to a wet type coal mine dust remover. BACKGROUND

[0002] The working principle of the wet type dust remover is that dust-containing gas is fully contacted with atomized water droplets after entering the dust remover, dust particles are combined with water droplets to form larger particle groups under the actions of inertia collision, interception, diffusion and coagulation, and then are settled to the bottom of the dust remover under the action of gravity, are discharged through a drainage system, and the purified gas is discharged through an exhaust port. During the use of the wet type dust remover, a part of dust will fall on the spray head during dust falling. When the equipment is not used, a part of dust will still enter the internal part of the wet type dust remover and adhere to the spray head due to the fact that dust always exists in the underground environment of the coal mine. With the lapse of time, the dust is continuously accumulated and gradually blocks the spray head, thereby affecting the normal work of the spray system.

[0003] After the spray head is blocked, the area originally responsible for spraying will lose water mist coverage. When the dust-containing gas flow passes through the dust remover, the gas flow will preferentially select a path with smaller resistance (i.e. an area without water mist or with sparse water mist) to flow, thereby bypassing the normal dust removal treatment area and forming a gas flow short circuit.

[0004] The gas flow short circuit causes the dust-containing gas to be discharged without being subjected to sufficient dust removal treatment, a large amount of dust cannot be effectively removed, the dust concentration of the discharged gas exceeds the standard, the environmental protection emission standard cannot be met, and the normal production of the coal mine and the surrounding environmental quality are seriously affected.

DETAILED DESCRIPTION

[0047] In order to make the technical means, creative features, purposes and effects realized by the application easy to understand, the application is further described below in combination with specific embodiments.

[0048] As Figures 1 to 11 shown, the wet coal mine dust collector provided by the application comprises a wet dust collector; the wet dust collector comprises a stand pipe 1; the stand pipe 1 is provided with an air pipe 3 at the bottom; the stand pipe 1 is provided with a stand cylinder 11 inside, and the top of the stand cylinder 11 is fixedly connected to the stand pipe 1 through a second annular plate 12; the bottom of the stand cylinder 11 is in the shape of a circular truncated cone; a space is left between the stand cylinder 11 and the stand pipe 1;

[0049] The first annular plate 13 is slid on the stand pipe 11; a plurality of air inlets 14 are arranged on the outer ring of the first annular plate 13 and located on the stand pipe 1, and the first annular plate 13 is located below the air inlet 14 in the initial state; a plurality of air outlets 15 are arranged on the outer ring of the second annular plate 12 and located on the stand pipe 1;

[0050] The annular partition layer 2 is fixedly connected to the outer ring of the stand pipe 1, and the top of the annular partition layer 2 is closed; a plurality of partition plate groups are fixedly connected in the annular partition layer 2, and each partition plate group includes two partition plates 21; the space between the two partition plates 21 of the partition plate group is a dust removal cavity 22; and the air inlet 14 and the air outlet 15 are located in the dust removal cavity 22;

[0051] A sliding plate 23 is slid in each dust removal cavity 22, and the sliding plate 23 is located above the air inlet 14 in the initial state; a cylinder 24 is fixedly connected to the sliding plate 23, and the cylinder 24 extends above the annular partition layer 2; two rectangular cylinders 25 are fixedly connected above the first annular plate 13, and the two rectangular cylinders 25 are located on the left and right sides of the stand pipe 11 respectively;

[0052] The rectangular cylinder 25 extends above the stand pipe 1 through the second annular plate 12; a third annular plate 26 is arranged above the stand pipe 1, and the cylinder 24 and the rectangular cylinder 25 are fixedly connected to the third annular plate 26; an electric push rod 27 is fixedly connected to the outer ring of the annular partition layer 2, and the extension rod of the electric push rod 27 is fixedly connected to the third annular plate 26;

[0053] Each dust removal cavity 22 is provided with a spraying assembly, and the spraying assembly is used for dust removal of the passing gas;

[0054] In this embodiment, a first motor is installed in the air pipe 3; the first motor is installed in a protection shell; a vortex blade 31 is installed on the first motor;

[0055] The annular partition layer 2 is fixedly connected with an annular bin 32 at the bottom; a plurality of partition blocks 33 are fixedly connected in the annular bin 32, and the partition blocks 33 correspond to the partition plates 21 one by one and are mutually adhered;

[0056] The stand pipe 1 is fixedly connected with a rectangular bin 34 at the bottom, and the annular bin 32 communicates with the rectangular bin 34 through a conduit; a base is arranged below the rectangular bin 34; a fixed ring 35 is fixedly connected to the outer ring of the annular partition layer 2, and the fixed ring 35 is fixedly connected to the base through a supporting leg.

[0057] When the dust in the mining area is treated, first start the wet dust collector, the wet dust collector will control the spray assembly to work, then control the electric push rod 27 to extend, the extended electric push rod 27 will drive the third annular plate 26 to move up, the third annular plate 26 moving up will gradually pull the plurality of cylinders 24 and the two rectangular cylinders 25 up, in the process of moving up the rectangular cylinder 25, the first annular plate 13 will be pulled up along the stand cylinder 11, and finally the first annular plate 13 is moved to the position below the air outlet 15, in the process of moving up the plurality of cylinders 24, the slide plate 23 in each dust removal cavity 22 will be pulled up respectively, when the slide plate 23 is moved to above the air outlet 15, control the electric push rod 27 to stop working.

[0058] Then, control the first electric motor to drive the scroll blade 31 to rotate, the rotating scroll blade 31 will suck the dust outside into the air pipe 3, and then into the stand pipe 1, since the first electric motor is installed in the protection shell, the dust can be avoided directly acting on the first electric motor, when the dust enters the stand pipe 1, since the stand pipe 1 is provided with the stand cylinder 11, and there is a gap between the stand cylinder 11 and the stand pipe 1, therefore the dust will flow upward along the circular table at the bottom of the stand cylinder 11, and gradually flow between the stand cylinder 11 and the stand pipe 1, then the dust will follow the airflow through the air inlet 14 into different dust removal cavities 22, the spray assembly in the dust removal cavity 22 will spray the dust flowing through, when the dust and the atomized water droplets are in full contact, the dust particles are combined with the water droplets to form larger particle groups under the action of inertia collision, interception, diffusion, coagulation, etc., and then settle in the annular bin 32 under the action of gravity, the purified gas will be discharged through the air outlet 15, and then discharged through the top of the stand pipe 1.

[0059] By providing a plurality of dust removal cavities 22, the dust gas entering the stand pipe 1 can be shunted, and the dust can be shunted into different dust removal cavities 22, and then the shunted dust can be dusted by the spray assembly, in this process, the dust can be dispersed to avoid the dust from being concentrated together, which will cause the dust density to be too large, and when the concentrated dust is dusted, the atomized water droplets cannot fully contact the dust, which will cause part of the dust to be discharged into the external environment again, thereby reducing the dust removal effect, and the dust with too large density is more likely to adhere to the spray assembly, which will cause the spray assembly to be blocked;

[0060] When the dust removal work is finished, the electric push rod 27 is controlled to retract, and the retracted electric push rod 27 drives the cylinder 24 and the rectangular cylinder 25 to move downward through the third annular plate 26, and the downward moving cylinder 24 and the rectangular cylinder 25 drive the sliding plate 23 and the first annular plate 13 to move downward, respectively, and in the process of moving downward of the first annular plate 13, the space between the vertical cylinder 11 and the stand pipe 1 is scraped, so that the residual dust is pushed downward, and in the process of moving downward of the sliding plate 23, the dust removal cavity 22 is scraped, so that the residual dust is pushed downward, and when the sliding plate 23 moves to the initial position, the sliding plate 23 is continuously controlled to move downward, and the downward moving sliding plate 23 continuously pushes the dust downward, and at the same time, the first annular plate 13 continuously moves downward and gradually moves to the position below the vertical cylinder 11, and when the sliding plate 23 moves to the position above the annular bin 32, the dust is pushed into the annular bin 32, and at the same time, the dust between the vertical cylinder 11 and the stand pipe 1 is pushed to fall and fall into the rectangular bin 34, and then the sliding plate 23 and the first annular plate 13 are controlled to move upward and return to the initial state, that is, the sliding plate 23 is above the air inlet 14, and the first annular plate 13 is below the air inlet 14, so that the air inlet 14 is blocked by the first annular plate 13;

[0061] In this process, by blocking the air inlet 14 by the first annular plate 13, the external dust can be prevented from entering the stand pipe 1 through the air pipe 3, and then entering the dust removal cavity 22 through the air inlet 14 and adhering to the spray assembly, gradually blocking the spray head 41, causing airflow short circuit in the subsequent dust removal process, causing dust concentration of exhaust gas to exceed standard, failing to meet environmental protection emission standard, and at the same time, by scraping the dust between the dust removal cavity 22 and the stand pipe 1 and the vertical cylinder 11 by the sliding plate 23 and the first annular plate 13, the residual dust can be pushed out, avoiding the increase of residual dust in the dust removal cavity 22 and the vertical cylinder 11, which increases the risk of blocking the spray assembly.

[0062] Since the annular bin 32 is fixedly connected with a plurality of partition blocks 33, and the partition blocks 33 correspond to the partition plates 21 one by one and are mutually attached, the different dust removal cavities 22 are prevented from being communicated, and the dust in different dust removal cavities 22 is prevented from entering other dust removal cavities 22 through the annular bin 32.

[0063] As an embodiment of the present application, the spray assembly comprises a rotating disc 4; a plurality of circular grooves are formed in the inner wall of the annular partition layer 2 in the dust removal cavity 22; and the rotating disc 4 is rotationally connected in the circular grooves;

[0064] A cylindrical groove is formed in the middle of the rotating disc 4, and the spray head 41 is installed in the cylindrical groove; and the spray head 41 is parallel to the dust removal cavity 22 in the initial state;

[0065] Uniformly arranged gear teeth 42 are fixedly connected to the outer circle surface of the rotating disc 4, and the gear teeth 42 are made of rubber material and are attached to the circular groove;

[0066] The side surface of the slide plate 23 adhered to the annular partition 2 is provided with uniformly arranged tooth grooves 43, and the tooth grooves 43 are engaged with the gear teeth 42;

[0067] The left side of the circular groove is provided with a movable groove; the spray head 41 is provided with a hose, and the hose extends into the movable groove; the outer side of the annular partition 2 is provided with a plurality of liquid tanks 44, and the liquid tanks 44 are all installed on the fixed ring 35 through vertical rods; the liquid tanks 44 are communicated with external water sources; the hose is communicated with the corresponding liquid tank 44;

[0068] In this embodiment, an intelligent flow meter 45 is installed on each hose, and the intelligent flow meter 45 is connected with a computer through a communication module, and the numerical value change of the intelligent flow meter 45 is monitored through the computer; control valves are installed in the air inlet 14 and the air outlet 15;

[0069] In this embodiment, a chute 46 is provided in the inner wall of the annular partition 2 below the spray head 41, and the chute 46 is communicated with the spray head 41 in the initial state; the chute 46 is communicated with the annular bin 32 through a connecting pipe.

[0070] Since the outer ring of the rotating disc 4 is fixedly connected with gear teeth 42 made of rubber material, when the slide plate 23 is pulled upward by the cylinder 24, the tooth grooves 43 provided on the slide plate 23 will gradually contact the gear teeth 42, and in the process of the slide plate 23 passing through the rotating disc 4, the rotating disc 4 will be gradually rotated, and the rotating rotating disc 4 will drive the spray head 41 to rotate, when the slide plate 23 passes through the rotating disc 4, the rotating disc 4 rotates by 90 degrees, and the spray head 41 points to the dust removal cavity 22 and is perpendicular to the dust removal cavity 22, when the dust enters the inside of the dust removal cavity 22, the atomized water droplets sprayed by the spray head 41 can reduce the dust, when the dust reduction is completed, the cylinder 24 will gradually restore the initial state of the slide plate 23, and in the process of the slide plate 23 moving downward, when the slide plate 23 passes through the rotating disc 4, the rotating disc 4 will be pushed to rotate in the opposite direction again, and the rotating disc 4 rotating in the opposite direction will gradually rotate into the circular groove and gradually restore the initial state, in this process, when the spray head 41 is not used, the spray head 41 can be rotated into the circular groove, and since the gear teeth 42 are adhered to the circular groove, the circular groove can be blocked to avoid the dust adhering to the spray head 41 through the circular groove, and the probability of clogging of the spray head 41 is further reduced;

[0071] At the same time, since the chute 46 is provided below the spray head 41, and the chute 46 is communicated with the annular bin 32 through a connecting pipe, when the spray head 41 restores to the initial state, the spray head 41 continues to spray water at this time, and in the process of spraying water by the spray head 41, the dust on the spray port of the spray head 41 can be sprayed off, and then the dust will flow out through the chute 46 and flow into the annular bin 32, in this process, the dust adhering to the spray head 41 cannot be removed, which causes the dust to dry on the spray head 41, thereby causing the spray head 41 to be clogged;

[0072] In the implementation process, since the intelligent flow meter 45 is installed on the hose connected with the spray head 41, and the intelligent flow meter 45 is connected with the computer through the communication module, the change of the value of the liquid passing through the intelligent flow meter 45 can be monitored through the computer. If the value of the intelligent flow meter 45 does not change for a long time, it can be judged that the spray head 41 connected with the intelligent flow meter 45 is blocked. At this time, the control valve in the air inlet 14 and the air outlet 15 of the dust removal chamber 22 where the spray head 41 is located is closed, so that the dust cannot enter the dust removal chamber 22 through the air inlet 14. Therefore, the dust removal chamber 22 is in a closed state. In this process, the dust removal chamber 22 with the blocked spray head 41 can be closed, thereby avoiding the dust removal of the dust removal chamber 22 with the blocked spray head 41, which leads to the ineffective removal of the dust, so that the dust is still discharged into the external environment. By setting the control valve, when the wet dust collector is not used, the control valve is closed, so that the dust in the stand pipe 1 cannot enter the dust removal chamber 22.

[0073] As an embodiment of the present application, the third annular plate 26 is provided with a liquid cavity 261, and the liquid cavity 261 is in communication with the cylinder 24 and the rectangular cylinder 25 respectively; the liquid cavity 261 is in communication with an external water source.

[0074] The sliding plate 23 is provided with a liquid groove; the first annular plate 13 is also provided with a liquid groove; the bottom of the sliding plate 23 is provided with a flow channel 28;

[0075] The bottom of the first annular plate 13 is also provided with uniformly arranged flow channels 28.

[0076] In this embodiment, the bottom of the sliding plate 23 is hinged with a baffle 29 through a torsional spring and a rotating shaft, and the baffle 29 is attached to the sliding plate 23 in the initial state and covers the flow channel 28;

[0077] The bottom of the first annular plate 13 is also hinged with uniformly arranged baffles 29 through a torsional spring and a rotating shaft, and the baffle 29 is attached to the first annular plate 13 in the initial state and covers the flow channel 28.

[0078] In the process of controlling the downward movement of the sliding plate 23 and the first annular plate 13, water is introduced into the liquid cavity 261 of the third annular plate 26. The water flows into the liquid grooves of the first annular plate 13 and the sliding plate 23 through the cylinder 24 and the rectangular cylinder 25 respectively, and then the water in the sliding plate 23 and the first annular plate 13 flows out through the flow channels 28 respectively. The water flowing out of the sliding plate 23 acts on the dust removal chamber 22, thereby cleaning the dust removal chamber 22. The water carries the scraped dust and falls into the annular bin 32. The water flowing out of the first annular plate 13 acts on the space between the stand cylinder 11 and the stand pipe 1, thereby cleaning the inside of the stand pipe 1 and the surface of the stand cylinder 11. Then the water carries the scraped dust and falls into the rectangular bin 34.

[0079] Since the flow channels 28 on the slide plate 23 and the first annular plate 13 are both attached by the torsion spring baffle 29, when dust passes through the flow channel 28, the baffle 29 blocks the flow channel 28, thus preventing the dust from entering the flow channel 28. When water is sprayed into the flow channel 28, it will push the baffle 29 open, and then the water will move down along the baffle 29 and carry away the dust.

[0080] In one embodiment of the present invention, a second motor is installed inside the vertical cylinder 11; a conical block 16 is rotatably mounted at the bottom of the vertical cylinder 11; the conical block 16 is in contact with the bottom of the vertical cylinder 11.

[0081] The outer ring of the conical block 16 is fixedly connected to a uniformly arranged scraper 17, and the scraper 17 extends to the frustum shape at the bottom of the vertical cylinder 11; the scraper 17 is located in the inner ring of the first annular plate 13 and does not intersect with the first annular plate 13.

[0082] In this embodiment, a ring 18 is fixedly connected to the top of the riser 1; the rectangular tubes 25 all pass through the ring 18 and are slidably connected to the ring 18; a filter screen 19 is installed inside the ring 18.

[0083] Because the bottom of the vertical cylinder 11 has a rotating conical block 16, when dust enters the vertical pipe 1, it will flow along the conical block 16, thereby reducing the obstruction to the dust. When the first annular plate 13 pushes the dust down, the second motor is controlled to drive the conical block 16 to rotate. The conical block 16 will drive the scraper 17 to rotate along the frustum at the bottom of the vertical cylinder 11, thereby scraping off the dust on the frustum of the vertical cylinder 11.

[0084] Since the top of the riser 1 is equipped with a filter screen 19, when the gas flowing out from the outlet 15 still contains some dust, the dust can be filtered again using the filter screen 19.
