[0043] The side of the lower box body 1 and the upper box body 7 is provided with a climbing frame 12, the climbing frame 12 improves the maintenance efficiency, the bottom of the lower box body 1 is communicated with a hopper 2, the hopper 2 is used for quickly recycling and processing impurities and the like with large volume and weight, one side of the hopper 2 is provided with an observation window 3, the observation window 3 improves the observation of the blocking condition in the hopper 2, the bottom of the lower box body 1 is uniformly provided with a plurality of supports 4, the bottom of the support 4 is provided with a buffer pad, the support 4 improves the stability of the lower box body 1 and the upper box body 7, the bottom of the hopper 2 is provided with a discharge device 5, the bottom of the discharge device 5 is provided with a discharge port 6, then the larger impurities and the like in the hopper 2 are directly discharged along the discharge device 5 and the discharge port 6 for processing, the top of the side of the upper box body 7 is communicated with an air outlet pipe 8, the other end of the air outlet pipe 8 is provided with an air extractor 9, the output end of the air extractor 9 is communicated with a clean air pipe 10, the air extractor 9 is started to apply suction, then the cleaned gas in the upper box body 7 is discharged along the air outlet pipe 8 and the clean air pipe 10, effectively realizing the efficiency and stability of gas discharge.

[0044] In use, the gas to be removed along the gas inlet pipe into the lower box 1 for subsequent removal of impurities, the controller control exhaust fan 9 start to exhaust, then the exhaust fan 9 by the air outlet pipe 8 on the upper box 7 and the lower box 1 inside the suction force, and the gas gravity greater than the suction force of the impurities directly under the action of gravity to the hopper 2 inside, and along the hopper 2 to the discharge device 5 inside, and ultimately along the discharge device 5 to the out of the mouth 6 for subsequent removal of impurities recovery, and the gravity is less than the suction force of the impurities under the action of suction force upward, to reach the outer bag 19 outer surface by the filter hole 20 of the screening effect on the impurities in the air filtration screening, further improve the clean and no gas discharge gas impurity, and after filtering through the filter hole 20 of the gas directly along the outer bag 19 of the inside to the vertical hole 18 end, and along the vertical hole 18 to the upper box 7, the clean gas in the upper box 7 along the air outlet pipe 8 to the exhaust fan 9 end, and ultimately along the clean air pipe 10 discharge, so as to obtain the required clean gas, avoid in actual use more dust and impurities, etc. Pollute the outside air.

[0047] The device has high efficiency, high stability, good adaptability, simple and efficient operation, and can realize reverse unblock of the outer bag 19 by means of pulse reverse impact, which has strong unblock performance, good cleanliness, strong dredging performance, energy saving and emission reduction, green environmental protection, and continuous and stable work.

[0048] Second embodiment

[0049] As Figures 4-10 shown, the first embodiment can be known that when the lower box 1 inside the cloth bag 19 is affected by the suction force of the suction fan 9, the stretching deformation occurs inside, which will cause the size of the filter hole 20 to be stretched and enlarged, and the filtering performance of the filter hole 20 to the gas will be reduced. The existing device lacks a detection device for the damage degree of the cloth bag 19, and when the cloth bag 19 is broken, the cleanliness of the exhaust gas will be reduced. When the impurities inside the filter hole 20 are cleaned by the pulse gas, the suction fan 9 needs to be closed for cleaning, which reduces the efficiency of the suction exhaust. At the same time, since the weight of the impurities discharged along the filter hole 20 is relatively light, it cannot quickly fall into the ash bucket 2 inside for impurity removal treatment when it floats inside the lower box 1. When the suction fan 9 is restarted, the impurities are re-sucked into the filter hole 20 and blocked, which affects the subsequent impurity filtration of the gas. In order to solve the above problems, the gas tank type pulse bag dust collector also includes: multiple groups of spray heads 34 are uniformly arranged on the bottom of the horizontal plate 17. The spray heads 34 spray misty purified water into the lower box 1. The impurities discharged along the filter hole 20 can be adsorbed into a group by the purified water, and the grouped impurities directly fall into the ash bucket 2 for subsequent recovery and impurity removal, avoiding the influence of the impurities on the subsequent gas impurity removal.

[0050] The inner wall of the cloth bag 19 is provided with an inner cloth bag 22. Multiple groups of staggered holes 42 are uniformly arranged in the inner cloth bag 22. The filter hole 20 is matched with the staggered hole 42. Therefore, when the inner cloth bag 22 moves upward relative to the outer cloth bag 19, the staggered area of the filter hole 20 and the staggered hole 42 increases, and the blocking area of the staggered hole 42 to the filter hole 20 increases, thereby neutralizing the size increase of the filter hole 20 when the outer cloth bag 19 is stretched and deformed, thereby effectively improving the recovery and filtration performance of the outer cloth bag 19 to the impurities in the gas.

[0051] Multiple groups of blocking rods 21 are uniformly arranged on the inner wall of the inner cloth bag 22. The blocking rod 21 mainly plays a blocking and supporting role, avoiding the outer cloth bag 19 and the inner cloth bag 22 from being greatly deformed under the action of the suction force of the suction fan 9, thereby reducing the integrity and filtration performance of the gas impurities. The side of the blocking rod 21 close to the inner cloth bag 22 is provided with a bellows 43, and the side of the bellows 43 close to the inner cloth bag 22 is provided with an elastic plate 44. The other end of the elastic plate 44 is in contact with the inner wall of the inner cloth bag 22. The arrangement of the elastic plate 44 avoids the damage of the structure of the inner cloth bag 22 caused by the friction contact between the inner cloth bag 22 and the inner blocking rod 21. When the inner cloth bag 22 is contracted inward, the bellows 43 is extruded by the elastic plate 44, and the bellows 43 correspondingly shrinks elastically. The bellows 43 contains flowing gas, so when the bellows 43 is extruded, the flowing gas moves.

[0052] The inner hole 46 is slidably connected with the slide rod 24. The outer surface of the slide rod 24 and the top of the side hole 45 at the top are provided with a sealing push block 47. The circumferential surface of the sealing push block 47 is frictionally and slidably connected with the inner wall of the inner hole 46. Therefore, when the amount of the circulating gas in the inner hole 46 increases, the gas pressure applied to the bottom of the sealing push block 47 by the circulating gas drives the sealing push block 47 to move upward, and the upward movement of the sealing push block 47 synchronously drives the slide rod 24 to move upward.

[0053] The inner hole 46 is slidably connected with the slide rod 24. The outer surface of the slide rod 24 and the top of the side hole 45 at the top are provided with a sealing push block 47. The circumferential surface of the sealing push block 47 is frictionally and slidably connected with the inner wall of the inner hole 46. Therefore, when the amount of the circulating gas in the inner hole 46 increases, the gas pressure applied to the bottom of the sealing push block 47 by the circulating gas drives the sealing push block 47 to move upward, and the upward movement of the sealing push block 47 synchronously drives the slide rod 24 to move upward.

[0054] The top and bottom of the slide rod 24 extend out of the inner hole 46 and are provided with splicing rods 25 close to one side of the inner cloth bag 22. The bottom of the splicing rod 25 is fixedly connected with the top and bottom of the inner cloth bag 22 through a connecting assembly. Therefore, when the slide rod 24 moves upward, the splicing rod 25 moves upward, and the inner cloth bag 22 moves upward through the connecting assembly. The inner cloth bag 22 moves upward relative to the outer cloth bag 19, the dislocation area of the dislocation hole 42 and the filter hole 20 increases, and the neutralization of the stretching of the filter hole 20 is realized, so as to ensure that the filtering area of the filter hole 20 for gas impurities is the same.

[0055] Specifically, the splicing rod 25 is in an inverted L-shaped structure. The inverted L-shaped structure ensures the synchronization of the movement of the slide rod 24 and the connecting assembly and the stability of the connection. The connecting assembly includes a connecting ring 23 fixedly connected to the top and bottom of the inner cloth bag 22. The other end of the splicing rod 25 is fixedly connected to the end of the connecting ring 23. Therefore, when the slide rod 24 moves upward, the top and bottom splicing rods 25 move upward by the same distance, and the inner cloth bag 22 moves upward by the same distance through the connecting ring 23. The inner wall of the inner hole 46 is provided with a sealing end ring 50. The inner wall of the sealing end ring 50 is sealingly and slidably connected with the outer wall of the slide rod 24. The sealing end ring 50 ensures the sealing of the inner hole 46 and the stability of the gas circulation, and further ensures the stability and upward and downward movement of the sealing push block 47 in the inner hole 46.

[0056] The top of the blocking rod 21 is provided with a transfer box 26, which is mainly used for realizing the circulation transfer of purified water. The transfer box 26 is fixedly connected with the bottom of the splicing rod 25 through a one-way hydraulic assembly. The one-way hydraulic assembly is arranged to realize the one-way circulation of the purified water, so as to realize the adsorption and agglomeration of the fine impurities by the purified water when the outer bag 19 is reversely pulsed to clean the blockage, thereby improving the recovery and impurity removal efficiency of the part of impurities.

[0057] The one-way hydraulic assembly comprises a transfer cavity 41 which is arranged at the top of the transfer box 26 and is in a hollow structure to facilitate the circulation of the purified water. The transfer cavity 41 is slidably connected with a sealing sliding plate 39. When the sealing sliding plate 39 moves upward, the air pressure in the transfer cavity 41 decreases. When the sealing sliding plate 39 moves downward, the air pressure in the transfer cavity 41 increases. The bottom of the sealing sliding plate 39 is provided with a connecting spring 40 which is fixedly connected with the inner bottom of the transfer cavity 41. The connecting spring 40 is arranged to ensure the stability and reset property of the sliding of the sealing sliding plate 39. The top of the sealing sliding plate 39 is provided with an extrusion rod 27 which is fixedly connected with the bottom of the splicing rod 25. Therefore, when the splicing rod 25 moves up and down along with the sliding rod 24, the bottom of the splicing rod 25 synchronously drives the extrusion rod 27 to move up and down, and the extrusion rod 27 drives the sealing sliding plate 39 to move up and down in the transfer cavity 41.

[0058] The inner wall of the top of the transfer cavity 41 is provided with a top sealing ring 49 which is sealingly and slidably connected with the outer wall of the extrusion rod 27. The top sealing ring 49 is arranged to ensure the sealing property of the transfer cavity 41 and the stability of the sliding of the extrusion rod 27.

[0061] In use, as known from the first embodiment, after the device is completed, the controller controls the exhaust fan 9 to start and applies suction force to the inside of the upper box body 7 and the lower box body 1 through the air outlet pipe 8, the impurity gas is introduced into the inside of the lower box body 1 along the air inlet pipe, after the impurity gas enters the inside of the lower box body 1, the impurities with gravity greater than the suction force received fall to the inside of the ash bucket 2 under the action of gravity, and fall to the discharge device 5 along the ash bucket 2, the impurities and the like in the inside of the discharge device 5 are discharged through the impurity outlet 6 for recovery.

[0062] And the gas in the lower box 1 reaches the end of the outer cloth bag 19 under the action of suction force, the outer wall of the outer cloth bag 19 is elastically deformed under the action of suction force and impurity gas, then the size of the filter hole 20 is stretched and increased, thereby reducing the filtering accuracy of the filter hole 20 to impurity gas, so when the outer cloth bag 19 moves to the end of the stop rod 21 and elastically deforms, the outer cloth bag 19 synchronously extrudes the inner cloth bag 22, the inner cloth bag 22 synchronously extrudes the elastic plate 44, the elastic plate 44 synchronously extrudes the corrugated pipe 43 and the connecting spring 40 and moves to the end of the stop rod 21, the gas in the corrugated pipe 43 flows to the inner hole 46 through the plurality of side holes 45, the gas pressure in the inner hole 46 increases and drives the sealing push block 47 to move upward, the sealing push block 47 moves upward and synchronously drives the slide rod 24 to move upward, the slide rod 24 moves upward and drives the top and bottom splicing rods 25 to move upward, the splicing rod 25 drives the inner cloth bag 22 to move upward through the connecting ring 23, the inner cloth bag 22 moves upward and synchronously drives the plurality of misaligned holes 42 to move upward, the misaligned holes 42 move and misalign relative to the filter holes 20, then the filter holes 20 are blocked by the inner cloth bag 22 and their filtering area is reduced, thereby neutralizing the increased size of the filter holes 20 due to stretching deformation, and ensuring the filtering stability and filtering accuracy of the filter holes 20.

[0063] At the same time, as the splicing rod 25 moves upward, the splicing rod 25 drives the bottom extrusion rod 27 to move upward, the extrusion rod 27 drives the bottom sealing slide plate 39 to move upward, the distance sensor detects an increased distance value and reaches the initial distance preset value, the volume in the transfer cavity 41 increases as the sealing slide plate 39 moves upward, and the gas pressure decreases, thereby exerting suction force on the purified water tank 30 through the change in gas pressure in the transfer cavity 41, and the purified water in the purified water tank 30 enters the transfer cavity 41 through the first inner cavity 35, the first one-way valve 36 and the first communication pipe 29, and the content of the purified water in the transfer cavity 41 continuously increases, which is convenient for subsequent adsorption and agglomeration of small impurities in the lower box 1.

[0064] And with the adsorption and filtration of the filter holes 20 inside the outer cloth bag 19 to the fine impurities, the amount of impurities filtered inside the filter holes 20 increases and is blocked, and the suction force applied to the outer cloth bag 19 by the exhaust fan 9 increases, and the outer cloth bag 19 is continuously elastically deformed towards the end of the blocking rod 21 under the action of the suction force, and the size of the filter holes 20 is continuously stretched and increased, and the outer cloth bag 19 drives the inner cloth bag 22 to extrude the elastic plate 44, the elastic plate 44 extrudes the bellows 43, and the flow gas inside the bellows 43 continuously enters the inner hole 46 through the multiple groups of side holes 45, and the amount of flow gas in the inner hole 46 continuously increases, and the sealing push block 47 is driven to move upwards by the gas pressure of the flow gas, and the sliding rod 24 is driven to move upwards by the sealing push block 47, and the splicing rod 25 is driven to move upwards by the sliding rod 24, and the inner cloth bag 22 is driven to move upwards by the splicing rod 25 through the connecting ring 23, and the inner cloth bag 22 drives the misaligned hole 42 to move upwards, and the misaligned area of the misaligned hole 42 and the filter hole 20 increases, thereby ensuring that the size of the filter hole 20 subjected to stretching increases is the same as the size of the filter hole 20 subjected to the blockage of the inner cloth bag 22, and the opening size of the filter hole 20 remains stable, thereby ensuring the filtering property and precision of the filter hole 20 to smaller impurities.

[0065] At the same time, as the splicing rod 25 moves upwards and drives the sealing sliding plate 39 to stretch the connecting spring 40 upwards through the extrusion rod 27, the distance value detected by the distance sensor continuously increases, and the suction force applied to the purification water tank 30 inside the transfer cavity 41 by the suction force increases, and the amount of purification water entering the transfer cavity 41 from the first inner cavity 35, the first one-way valve 36 and the first communication pipe 29 increases, and the amount of purification water inside the transfer cavity 41 continuously increases.

[0066] When the outer cloth bag 19 is damaged, the outer cloth bag 19 is elastically deformed by the suction force of the exhaust fan 9, and the size of the outer cloth bag 19 decreases, and the extrusion force of the outer cloth bag 19 on the bellows 43 decreases, and the elastic plate 44 is reversely moved under the action of the elastic force of the return spring 48, and the flow gas in the inner hole 46 reversely enters the bellows 43 through the side hole 45, and the extrusion force on the bottom of the sealing push block 47 decreases and drives the sliding rod 24 to move downwards, and the sliding rod 24 drives the splicing rod 25 to move downwards, and the splicing rod 25 drives the sealing sliding plate 39 to move downwards through the extrusion rod 27, and the distance value detected by the distance sensor decreases and is less than the initial distance preset value, thereby indicating that the outer cloth bag 19 or the inner cloth bag 22 is damaged at this time, and the splicing rod 25 drives the inner cloth bag 22 to move downwards and coincide with the outer cloth bag 19 through the connecting ring 23, thereby temporarily filtering the outer cloth bag 19 with the inner cloth bag 22, and avoiding the unfiltered impurity gas from being discharged and polluting the environment when the outer cloth bag 19 is damaged during the filtering process.

[0067] Specifically, when a certain side of the outer cloth bag 19 is damaged, the actual extrusion force of the outer cloth bag 19 and the inner cloth bag 22 at this position on the elastic plate 44 is smaller than that at other positions, and the distance value detected by the distance sensor close to this position is smaller than that detected by the distance sensor at other positions. Therefore, the damage position of the outer cloth bag 19 can be quickly obtained by means of the decrease of the distance value detected by the plurality of distance sensors, thereby improving the efficiency of the later maintenance and replacement of the outer cloth bag 19.

[0068] As the outer cloth bag 19 continuously filters impurity gas, the amount of blocked filter holes 20 increases, the distance that the outer cloth bag 19 extrudes the inner cloth bag 22 to move close to the end of the stop rod 21 increases, the distance value detected by the distance sensor increases and reaches the maximum distance preset value, which indicates that the amount of blocked filter holes 20 in the outer cloth bag 19 has reached the preset value, and then the filter holes 20 need to be cleaned by reverse pulse gas. Therefore, the controller controls the pulse valve 14 to open, and the gas in the gas tank 13 enters the air pipe 15 through the pulse valve 14, and then reaches the pulse nozzle 16 end and is sprayed into the vertical hole 18. The vertical hole 18 inside the outer cloth bag 19 is subjected to the action of the reverse pulse gas, so that the outer cloth bag 19 and the inner cloth bag 22 are both elastically deformed away from the end of the stop rod 21, and the impurities and the like clamped in the filter holes 20 are reversely separated from the filter holes 20 and enter the lower box body 1 under the action of the pulse gas.

[0069] Therefore, due to the elastic deformation of the outer cloth bag 19 and the inner cloth bag 22 away from the end of the stop rod 21, the extrusion force of the inner cloth bag 22 on the elastic plate 44 decreases, and the elastic plate 44 is reversely moved to restore the original position under the elastic force of the reset spring 48. The elastic plate 44 synchronously drives the bellows 43 to increase in volume and restore the original position, the internal pressure of the bellows 43 decreases, the flow gas in the inner hole 46 reversely flows to the inside of the bellows 43 through the plurality of side holes 45, the supporting force of the flow gas on the bottom of the sealing push block 47 decreases, and the sealing push block 47 drives the sliding rod 24 to move downward to restore the original position. The sliding rod 24 drives the splicing rod 25 to move downward to restore the original position, and the splicing rod 25 drives the inner cloth bag 22 to move downward to restore the original position through the connecting ring 23. At this time, the misaligned hole 42 in the inner cloth bag 22 is coincident with the filter hole 20, and the impurities and the like in the misaligned hole 42 and the filter hole 20 are reversely discharged into the lower box body 1 under the action of the pulse gas.

[0070] With the downward movement of the splicing rod 25, the extrusion rod 27 is moved downward, and the sealing slide plate 39 is moved downward to the minimum value under the elastic force of the connecting spring 40, the distance value detected by the distance sensor decreases to zero, the sealing slide plate 39 moves downward to the purified water in the centering cavity 41 to apply extrusion force, so that the purified water is discharged to the inside of the second inner cavity 37 along the second communication pipe 32 and the second one-way valve 38, and enters the drain pipe 33 along the second inner cavity 37, and reaches the spray head 34 end along the drain pipe 33, the spray head 34 sprays the purified water in the form of water mist to the inside of the lower box body 1, then the smaller impurities in the lower box body 1 are adsorbed into groups under the action of the water mist, the gravity of the impurity water group is greater than the suction force of the air extractor 9, then the impurity water group falls into the hopper 2 along the lower box body 1, and is finally discharged through the discharge device 5 along the discharge port 6, and the impurities attached to the inner wall of the lower box body 1 can also be adsorbed and discharged by the purified water mist, effectively improving the cleanliness and dust-free nature of the device, and the process also realizes the non-stop cleaning of the air extractor 9, the cleaning efficiency is higher, and the filtering effect is better.

[0071] When the reverse pulse cleaning of the outer cloth bag 19 and the inner cloth bag 22 is completed, the controller controls the pulse valve 14 to stop working, then the outer cloth bag 19 drives the inner cloth bag 22 to continue to move close to the end of the blocking rod 21 under the suction force of the air extractor 9 and applies extrusion force to the elastic plate 44, and the device continues to repeat the above process to remove impurities from the gas.

[0072] The device has high filtering efficiency, good filtering effect, strong cleaning performance, and strong cleaning adaptability. When the outer cloth bag 19 is elastically deformed under the action of the suction force, the size of the filter hole 20 changes, the inner cloth bag 22 moves relative to the outer cloth bag 19 to drive the misaligned hole 42 to move, and then the opening area of the filter hole 20 is adjusted by the misaligned size of the misaligned hole 42 and the filter hole 20, to ensure the filtering accuracy and stability of the filter hole 20. When the outer cloth bag 19 is damaged due to long-term use, the reverse movement of the sealing slide plate 39 and the inner cloth bag 22 driven by the splicing rod 25 can provide timely damage information and damage position of the outer cloth bag 19, and temporarily compensate for the filtering of the outer cloth bag 19 by the inner cloth bag 22, to improve the stability and resistance of the device. When the outer cloth bag 19 is cleaned by reverse pulse, the small impurities discharged along the filter hole 20 are adsorbed into groups by the cooperation of the water mist, the adsorption and recovery effect of the lighter impurities is improved, the non-stop reverse cleaning process is realized, and the influence on the subsequent gas impurity filtering is effectively avoided.
