Description

Technical Field

[0001] The present invention relates to the technical field of dust treatment, in particular to a dust treatment device for coal mining and a treatment method thereof. Background Art

[0002] In coal mining operations, dust treatment is a key link in ensuring production safety and environmental compliance. Wet scrubbers are widely used due to their low cost and wide adaptability. The core of wet scrubbers is to achieve air purification by adsorbing dust particles through water. In order to improve the dissolution saturation problem caused by long-term aeration in traditional single-chamber scrubbers, the existing technology generally adopts a parallel scrubbing chamber and sedimentation chamber design to delay the failure of the water body. As disclosed in patent announcement number CN212867623U, the existing technology is specifically a dust treatment device for coal mining, including a water tank, a support leg welded to the bottom of the water tank, a first support rod welded to one side of the support leg, a second support rod welded to the side of the water tank close to the first support rod, a third support rod welded to the side of the water tank close to the second support rod, and a fourth support rod welded to the side of the water tank away from the support leg; however, similar solutions still have the following technical bottlenecks.

[0003] Although the parallel chambers are aerated separately, the violent water flow fluctuations generated by the gas injection in the scrubbing chamber will be transmitted to the adjacent sedimentation chamber through the connecting structure, destroying the sedimentation environment. At the same time, the disturbance causes the settled sludge at the bottom of the sedimentation chamber to be stirred up again and returned to the scrubbing chamber with the circulating water flow, reducing the water purification efficiency and forming a vicious cycle of "treatment-pollution".

[0004] In addition, traditional static sedimentation can only collect sludge far away from the aeration port. The accumulation in the aeration area needs to be manually cleaned after shutdown, resulting in low equipment utilization. At the same time, the sedimentation chamber lacks the ability to clean sludge online. The water body needs to be drained regularly and the sludge needs to be manually scraped off. The single maintenance takes a long time, affecting continuous production. Finally, evaporation and sludge carryover cause the water level to drop, but there is a lag in manual water replenishment, resulting in a large fluctuation range of the water level in the washing chamber, which in turn leads to unstable washing effect.

[0023] First, the scrubber body of the present invention is equipped with multiple parallel sedimentation chambers and scrubbing chambers. After being pre-filtered by a spiral dust collector, the gas is introduced into the scrubber through an air pipe. The inclined bottom design of the scrubbing chamber, combined with the uniform air outlet holes on the extended bottom cavity plate, disperses the gas into microbubbles, increasing the gas-liquid contact area and significantly improving the dust dissolution efficiency. At the same time, multiple independent chambers are recycled to avoid saturation caused by long-term aeration of a single water body, maintaining continuous and efficient dust adsorption capacity.

[0025] Third: In the present invention, the floating block is sleeved on the end of the liquid receiving pipe, and the internal annular groove and the channel groove form a valve control structure. When the water level drops and the floating block sinks, the annular groove aligns with the liquid outlet hole to achieve automatic water replenishment; and when the water level rises and the floating block floats, the annular groove is dislocated to close the liquid outlet hole, thereby stopping water replenishment.

[0037] The present invention is described in detail below, clearly and completely describing the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only some embodiments of the present invention, not all embodiments. All other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making any creative efforts shall fall within the scope of protection of the present invention.

[0038] The present invention provides a coal mining dust treatment device and a treatment method thereof through improvement. The technical solution of the present invention is:

[0039] Example 1

[0040] like Figures 1 to 8 As shown, an embodiment of the present invention provides a dust treatment device for coal mining, comprising a mounting base plate 1, on which an air washing component, a slag removal component, and a water supply component are arranged;

[0041] The air washing assembly includes an air washing body 5 arranged above the mounting base plate 1, and a plurality of sedimentation chambers 38 are provided on the air washing body 5 at equal distances, and a connected air washing chamber 39 is provided on one side of the sedimentation chamber 38. The bottom of the air washing chamber 39 is inclined, and a connected extended side chamber 44 is also provided on one side of each sedimentation chamber 38. An air washing cylinder 34 is provided in each air washing chamber 39; by utilizing the multiple air washing chambers 39 and sedimentation chambers 38, multiple independent chambers are recycled to avoid long-term aeration of a single water body leading to dissolution saturation, thereby maintaining continuous and efficient dust adsorption capacity; at the same time, it can give the sedimentation chamber 38 sufficient sedimentation time.

[0042] The slag removal assembly includes a transmission belt 28 disposed inside the sedimentation chamber 38. A rubber seat is fixedly connected to the outside of each transmission belt 28, and a filter plate 29 is fixedly connected to the rubber seat.

[0043] The water replenishment component includes a plurality of liquid receiving pipes 45 fixedly connected to the gas washing body 5. The liquid receiving pipes 45 are in a tree-like structure, and the bottom ends of the liquid receiving pipes 45 are fixedly connected to the plurality of extended side cavities 44. The ends of the liquid receiving pipes 45 are provided with a plurality of liquid outlet holes 48, and the ends of the liquid receiving pipes 45 are movably sleeved with a plurality of floating blocks 46. The floating blocks 46 are provided with an annular groove 50, and each of the floating blocks 46 is provided with a channel groove 51 connected to the annular groove 50. With the above structure, the buoyancy is used to drive the water replenishment, and the floating blocks 46 is sleeved on the end of the liquid receiving pipe 45, and the internal annular groove 50 and the channel groove 51 form a valve-controlled structure. As the air washing component and the slag removal component are running, the water level drops and the float 46 sinks. At this time, the annular groove 50 is aligned with the liquid outlet 48 to achieve automatic water replenishment; when the water level is replenished and rises, the float 46 floats up until the annular groove 50 and the liquid outlet 48 are misaligned and closed, thereby automatically stopping water replenishment; thereby ensuring that there is always an effective air washing water level in the air washing chamber 39, ensuring the air washing effect of the device.

[0044] Furthermore, a pair of side baffles 15 are fixed at the top of the gas washing body 5 near the sedimentation chamber 38, and an oblong plate 16 is fixed on the top of the side baffles 15. A transmission roller 17 is installed between each pair of oblong plates 16 for common rotation, and a top roller 18 is installed between each pair of side baffles 15 for common rotation. A bottom roller 30 is installed for common rotation at the bottom of each sedimentation chamber 38, and a transmission belt 28 is sleeved on the bottom roller 30 and the top roller 18. In order to further enhance the buoyancy that can be generated by the floating block 46, a cavity 47 is opened near the bottom of the floating block 46, and a connecting spring 49 is fixed between the floating block 46 and the top of the extended side chamber 44. The provided connecting spring 49 is used to offset the friction between the floating block 46 and the extended side chamber 44.

[0045] Furthermore, a plurality of supporting stands 7 are fixedly installed on the top of the mounting base plate 1, and a connecting block 13 is fixed on one side of each of the supporting stands 7. A receiving ring groove plate 9 is fixedly connected to one side of each of the connecting blocks 13. A material leakage port 10 is provided on the receiving ring groove plate 9, and a collecting box 6 is placed near the material leakage port 10 on the mounting base plate 1; the collecting box 6 is used to collect the falling material discharged from the material leakage port 10.

[0046] Furthermore, a plurality of support plates 23 corresponding to the sedimentation chamber 38 are fixedly mounted on the outer wall of the gas washing body 5, a pair of guide cylinders 24 are fixed on each support plate 23, and guide rods 25 are slidably mounted in the guide cylinders 24 in the vertical direction, and the top of each pair of guide rods 25 is fixedly connected to a folded scraper plate 14, and the bottom end of the folded scraper plate 14 is inclined outward, and a scraper 11 is fixedly mounted on one side of each support plate 23, and the scraper 11 is adapted to the receiving ring groove plate 9; through the above structure, when the gas washing body 5 rotates, it can drive the support plate 23 and the corresponding scraper 11 to rotate, thereby scraping the inner wall of the receiving ring groove plate 9, and falling into the collection box 6 through the leakage port 10, without the need for manual intervention throughout the process.

[0047] As a further embodiment of the present invention, Figure 4 、 Figure 6 and Figure 8 As shown, the top ends of the plurality of support frames 7 are fixedly connected to a top ring frame 8, and a plurality of folding drum holders 12 are fixedly installed on the top ring frame 8, and the folding drum holders 12 are rotatably installed with transmission beams 20, and mutually meshing transmission conical teeth 19 are fixedly installed between the transmission beams 20 and the transmission rollers 17, and an incomplete conical gear ring 22 is fixedly installed at the bottom of the top ring frame 8, and the other end of each transmission beam 20 is fixedly installed with a driven conical tooth 21 adapted to the incomplete conical gear ring 22, and the transmission rollers 17 are fixedly installed with the driven conical teeth 21 adapted to the incomplete conical gear ring 22. A transmission belt 37 is provided between both ends and the top roller 18. With the above structure, when the transmission roller 17 is arranged, it can rotate along with the scrubber body 5. When the driven conical teeth 21 contact the incomplete conical gear ring 22, it can drive the transmission beam 20 to rotate. Then, through the transmission effect of the transmission conical teeth 19, the top roller 18 is driven to rotate in cooperation with the transmission belt 37, thereby driving the transmission belt 28 to rotate. The filter plate 29 is synchronously circulated to salvage the mud residue in the sedimentation chamber 38 in real time.

[0048] During the period from the time the filter plate 29 leaves the water surface to the time it contacts the folded scraper plate 14, the water it carries can be drained to minimize water loss in the gas washing body 5. When the filter plate 29 contacts the folded scraper plate 14, since a rubber seat is provided on one side of the filter plate 29, the folded scraper plate 14 can scrape the filter plate 29 by utilizing its deformable feature to remove surface mud. At the same time, the setting of the filter plate 29 can enhance the flow stabilization effect in the sedimentation chamber 38, thereby improving the mud sedimentation efficiency.

[0049] On the other hand, by utilizing the above-mentioned transmission design, the slag removal operation is performed only when the scrubbing body 5 is rotating. The scrubbing and sedimentation operations are carried out simultaneously at other times without affecting each other, thereby reducing energy consumption while ensuring the scrubbing effect on the air.

[0050] Further, such as Figure 8 As shown, each guide rod 25 is fixedly connected to a folded transmission rod 26, and the ends of the folded transmission rods 26 are provided with long circular groove ends 27 of an integral structure, and each top roller 18 is fixedly installed with a Z-type drive rod 52 at the center of both ends of the circle, and the other end of the Z-type drive rod 52 is movably connected to the long circular groove end 27; through the above structure, when the top roller 18 rotates, the Z-type drive rod 52 can cooperate with the guide cylinder 24 and the guide rod 25 to make the folded scraper plate 14 reciprocate in the vertical direction, thereby scraping the filter plate 29 more dynamically, and at the same time, it can reduce the adhesion of mud residue on the surface of the folded scraper plate 14.

[0051] Furthermore, the top of the liquid receiving pipe 45 is connected to the liquid supply pipe 43 through an adapter, and the liquid supply pipe 43 is connected to an external liquid supply device, which maintains a low-pressure water supply; a fixed cover 32 is detachably installed on the top of the gas washing body 5, and a bottom cover 33 is fixed to the outer wall of each gas washing cylinder 34, and the bottom cover 33 is detachably fixed to the top of the gas washing body 5; using the above design, the gas washing cylinder 34 is fixed to the top of the gas washing body 5 through the bottom cover 33, and the fixed cover 32 is detachable, which is convenient for cleaning blockages.

[0052] Furthermore, an extended bottom cavity plate 35 is fixed to the bottom end of each air washing cylinder 34, and the extended bottom cavity plate 35 is parallel to the bottom of the air washing cavity 39. The extended bottom cavity plate 35 is provided with evenly distributed air outlet holes 36; the bottom of the air washing cavity 39 is tilted to match the parallel layout of the extended bottom cavity plate 35, which can effectively prevent dust accumulation from clogging the air outlet holes 36.

[0053] Furthermore, a spiral dust collector 2 and a supporting base plate 4 are fixedly mounted on the mounting base plate 1. The top of the spiral dust collector 2 is fixedly connected to an air supply pipe 3. The other end of the air supply pipe 3 is flush with the top of the air washing cylinder 34. A control panel 31 is fixed to one side of the spiral dust collector 2. The supporting base plate 4 is rotatably connected to the air washing body 5. A transmission port is provided at the bottom of the air washing body 5. A worm gear 42 is fixed to the bottom of the air washing body 5. A drive motor 40 is fixed to the top of the supporting base plate 4. A worm 41 is fixed to the output shaft of the drive motor 40. In order to improve the stability of the air washing body 5 after rotation adjustment, the worm 41 is adapted to the worm gear 42 and the thread lead angle between the two is less than the friction Corner rubbing; the spiral dust collector 2 is set up to pre-treat the air, that is, to remove large particles of dust therein and reduce the operating pressure of the air washing component. At the same time, the control panel 31 can be used to control the drive motor 40. The drive motor 40 is specifically a stepping motor. Each time it is driven, it can drive the air washing body 5 to rotate ninety degrees through the transmission action of the worm 41 and the worm gear 42. In this way, the air washing chamber 39 can be quickly connected and replaced. During the rotation process, the air supply pipe 3 can be briefly in contact with the fixed cover 32 and closed until it is connected to the next air washing cylinder 34. Since the time is short, the external suction equipment does not need to be shut down at this time, thereby realizing continuous non-stop operation.

[0054] Example 2

[0055] This embodiment provides a method for treating dust from coal mining, which is applied to the dust treatment device for coal mining in the first embodiment. The method includes the following steps:

[0056] Step 1: Install the mounting base plate 1 on a mobile vehicle or fix it on the ground. At the same time, use an external suction device to pass air into the spiral dust collector 2, and use the spiral dust collector 2 to remove large particles of dust in the air;

[0057] Step 2: The air treated by the spiral dust collector 2 is passed into the scrubbing assembly for scrubbing treatment, and the multiple scrubbing chambers 39 and sedimentation chambers 38 are used for recycling to avoid prolonged aeration. Specifically, each time the drive motor 40 is driven, the worm 41 and the worm gear 42 drive the scrubbing body 5 to rotate 90 degrees, thereby quickly connecting and replacing the scrubbing chambers 39 to achieve continuous non-stop operation. The multiple scrubbing chambers 39 and sedimentation chambers 38 are used to recycle multiple independent chambers, avoiding the long-term aeration of a single water body leading to dissolution saturation and maintaining continuous and efficient dust adsorption capacity. At the same time, the sedimentation chamber 38 is given sufficient sedimentation time.

[0058] Step 3: Use the slag removal assembly to salvage and remove impurities in the sedimentation chamber 38; specifically, when the transmission roller 17 is arranged to rotate along with the gas scrubber body 5, when the driven conical teeth 21 contact the provided incomplete conical gear ring 22, the transmission beam 20 is driven to rotate, and then through the transmission effect of the transmission conical teeth 19, the top roller 18 is driven to rotate in conjunction with the transmission belt 37, thereby driving the transmission belt 28 to rotate, and the filter plate 29 is synchronously circulated to salvage the mud residue in the sedimentation chamber 38 in real time;

[0059] During the period from when the filter plate 29 leaves the water surface until it contacts the folded scraper plate 14, the water carried by the filter plate 29 can be drained to minimize water loss in the gas washing body 5. When the filter plate 29 contacts the folded scraper plate 14, the rubber seat provided on one side of the filter plate 29 utilizes its deformable characteristics to enable the folded scraper plate 14 to scrape the filter plate 29 and remove surface mud. When the top roller 18 rotates, the Z-shaped drive rod 52 cooperates with the guide cylinder 24 and the guide rod 25 to cause the folded scraper plate 14 to reciprocate in the vertical direction, thereby scraping the filter plate 29 more dynamically and reducing the adhesion of mud to the surface of the folded scraper plate 14.

[0060] At the same time, the extended side cavity 44 is provided and cooperated with the water replenishment component to perform adaptive water replenishment to ensure the water level in the air washing chamber 39, so as to ensure the air washing effect and fully utilize the water resources. Specifically, the buoyancy is used to drive the water replenishment, and the float 46 is sleeved on the end of the liquid receiving pipe 45. The internal annular groove 50 and the channel groove 51 form a valve-controlled structure. As the air washing component and the slag removal component are operated, the water level drops and the float 46 sinks. At this time, the annular groove 50 is aligned with the liquid outlet 48 to realize automatic water replenishment. When the water level is replenished and rises, the float 46 floats up until the annular groove 50 and the liquid outlet 48 are misaligned and closed, thereby automatically stopping the water replenishment. This ensures that there is always an effective air washing water level in the air washing chamber 39 to ensure the air washing effect of the device.

[0061] The above description is intended to enable one skilled in the art to implement or use the present invention. Various modifications to these embodiments will be readily apparent to one skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention is not limited to the embodiments shown herein but is intended to conform to the widest scope consistent with the principles and novel features disclosed herein.
