[0021] The driving assembly includes a slide rail 101, an electric slider 102 and a driving member 103; four slide rails 101 are fixedly connected to the housing 1; an electric slider 102 is slidably connected to each slide rail 101, and each electric slider 102 is fixedly connected to the upper side of the adjacent isolation cover 5. The isolation cover 5 and the scraping ring 6 are driven by the electric slider 102 to move up and down to scrape and clean the dust on the outer surface of the dust removal bag 2; four driving members 103 are fixedly connected to the upper side of the housing 1, and the driving member 103 is a multi-stage electric push rod; the telescopic end of each driving member 103 is fixedly connected to the adjacent air injection pipe 7, and the air injection pipe 7 is driven by the driving member 103 to move up and down.

[0022] Each isolation cover 5 is set to be frustum-shaped.

[0023] Each isolation cover 5 is made of corrosion-resistant material.

[0024] The side of each scraping ring 6 away from the dust removal bag 2 is set to be arc-shaped, reducing the friction force between the scraping ring 6 and the dust, so as to prevent the scraped dust impurities from adhering to the scraping ring 6 to the greatest extent and affecting the cleaning effect of the scraping ring 6.

[0025] The annular diameter of the air injection pipe 7 is larger than the inner diameter of the dust removal bag 2.

[0026] The working process of this embodiment is as follows: The working process of the existing purification device is as follows. First, start the external pump 1 and the external pump 2. The unpurified air flow is transported to the intake ring 3 through the external pump 1. Then, the air flow is transported between the outer surface of the dust removal bag 2 and the inner wall of the isolation cover 5 through the intake holes 3001 of the intake ring 3. Then, through the suction force generated by the external pump 2, the air flow between the outer surface of the dust removal bag 2 and the inner wall of the isolation cover 5 passes through the dust removal bag 2 and enters the inner periphery of the dust removal bag 2. Thus, the dust carried by the air flow is intercepted on the outer surface of the dust removal bag 2, thereby realizing the purification of the air flow. Finally, the air flow in the air outlet pipe 4 is discharged into the atmosphere through the external pump 2.

[0027] In view of the problems that the internal space of the purification equipment is limited, the presence of the isolation cover 5 makes it difficult for the operator to clean and maintain the equipment, and during the cleaning process, wet dust is likely to form mud cakes on the outer surface of the dust removal bag 2 and it is difficult to completely clean it through pulsed air flow, the solution is as follows. When the purification equipment has been working for a period of time and it is necessary to clean the built-in dust removal bag 2, when cleaning the first dust removal bag 2, close the solenoid valve on the air pipe between the first air inlet ring 3 and the external pump 1, so that the uncleaned gas no longer enters between the first dust removal bag 2 and the isolation cover 5 through the air inlet ring 3. The solenoid valves connected to the remaining air inlet rings 3 are normally opened, that is, the remaining dust removal bags 2 work normally. At this time, there is no air flow in the first dust removal bag 2. Control the electric slider 102 to drive the upper side of the first isolation cover 5 and the adjacent scraping ring 6 to move downward. The isolation cover 5 gradually contracts downward, the baffle 5003 gradually moves away from the extrusion rod 3002, and rotates upward under the action of the torsion spring and gradually fits with the lower side of the ventilation hole 5002, so as to block the ventilation hole 5002. The scraping ring 6 will scrape and clean the dust around the dust removal bag 2. At the same time, start the external pump 3, so that the air flow enters the spray pipe 7 through the telescopic pipe and is sprayed out from the jet groove of the spray pipe 7 to the outside of the dust removal bag 2. Then control the driving member 103 to drive the spray pipe 7 to move downward synchronously with the scraping ring 6. Then, under the impact of the air flow sprayed out from the spray pipe 7, the dust impurities adhering in the pores of the dust removal bag 2 are blown outwards. At the same time, use the scraping ring 6 to scrape and clean the dust impurities adhering to the outer surface of the dust removal bag 2, so as to prevent the wet dust impurities from adhering in the pores of the dust removal bag 2 during the cleaning by the scraping ring 6 to the greatest extent and affecting the subsequent purification effect of the dust removal bag 2. At the same time, as the upper side of the isolation cover 5 moves downward, the ventilation hole 5002 is blocked by the baffle 5003, thereby preventing the air flow sprayed out from the spray pipe 7 from blowing the dust scraped by the scraping ring 6 into the equipment through the ventilation hole 5002 and causing pollution inside the equipment. Since the annular diameter of the spray pipe 7 is larger than the inner diameter of the dust removal bag 2 and the dust removal bag 2 is made of elastic deformation material, when the spray pipe 7 moves downward, the part of the dust removal bag 2 in contact with the spray pipe 7 will bulge outwards. The dust removal bag 2 is expanded outwards by the spray pipe 7 to enlarge the pores on the dust removal bag 2, so as to improve the cleaning effect of the air flow of the spray pipe 7 on the dust. At the same time, under the expanding support of the spray pipe 7, the dust removal bag 2 fits more closely with the scraping ring 6. Thus, the cleaning effect of the scraping ring 6 on the dust removal bag 2 is further improved. At the same time, when the operator needs to maintain the equipment, control the electric slider 102 to drive the upper side of the isolation cover 5 and the scraping ring 6 to move downward, so that the isolation cover 5 contracts, thereby increasing the operation space inside the purification equipment and improving the convenience of personnel operation.

[0028] After the first dust removal bag 2 is cleaned, turn off the external pump 3. The operator only needs to remove the disassembly and assembly part 5001, and collect and process the dust and impurities scraped from the dust removal bag 2 uniformly, thus avoiding the direct fall of dust inside the purification equipment, eliminating the need for additional cleaning of the interior of the purification equipment, reducing the cleaning cost. After the dust is processed, control the electric slider 102 and the driving part 103 to drive the upper side of the isolation cover 5, the scraping ring 6 and the air injection pipe 7 to move upward respectively and return to the initial position. As the isolation cover 5 moves upward, the baffle 5003 will gradually be squeezed by the extrusion rod 3002 and open downward. At this time, the air inlet hole 3001 of the air inlet ring 3 is in communication with the air vent hole 5002 of the isolation cover 5. Then, start the solenoid valve connected to the first air inlet ring 3 to make the first dust removal bag 2 resume operation. Then, close the solenoid valve connected to the air pipe of the second air inlet ring 3 and repeat the above cleaning steps, thus realizing cleaning without stopping the machine and improving the cleaning efficiency of the equipment.

[0029] Considering that the dust intercepted and filtered by the dust removal bag 2 is in a wet state, over time, the dust adhering to the outer surface of the dust removal bag 2 will gradually slide downward and accumulate, resulting in excessive dust and impurities accumulating at the bottom of the dust removal bag 2, affecting the normal contraction of the isolation cover 5. By setting the isolation cover 5 in a frustum shape, sufficient space is reserved between the lower side of the isolation cover 5 and the dust removal bag 2, thus preventing excessive dust accumulation from hindering the contraction of the isolation cover 5.

[0030] Embodiment 2 On the basis of Embodiment 1, as Figures 1 - 6 shown, a dust concentration detector is installed on each connecting pipe 4001 to monitor the dust concentration flowing in the connecting pipe 4001 in real time, so as to judge whether the dust removal bag 2 is damaged.

[0031] It also includes a quick-release component, which includes a connecting rod 201, a clamping ring 202 and a blocking block 203; four connecting rods 201 are fixedly connected to the housing 1; a clamping ring 202 is fixedly connected to each air inlet ring 3; a blocking block 203 is communicated with each connecting pipe 4001; each connecting pipe 4001 is made of an elastic deformation material.

[0032] Each connecting rod 201 passes through the blocking block 203, and the blocking block 203 is connected to the connecting rod 201 in a damped sliding connection manner, increasing the friction between the connecting rod 201 and the blocking block 203, thereby enhancing the blocking effect of the blocking block 203 on the purified air flow and maximizing the stability of the blocking block 203 during the operation of the dust removal bag 2.

[0033] It also includes a sealing ring 301; a sealing ring 301 is fixedly connected to each air inlet hole 3001.

[0034] The working process of this embodiment is as follows: Considering that the dust removal bag 2 may be damaged, aged or perforated after long-term use, which may affect the purification effect. To solve the above problems, the dust concentration in the connecting pipe 4001 is monitored in real time by a dust concentration detector. When the dust removal bag 2 is damaged, aged or perforated, the unfiltered dust will directly enter the connecting pipe 4001 along with the purified gas, resulting in a significant increase in the dust concentration in the connecting pipe 4001. It indicates that the dust removal bag 2 has been damaged. Then the dust concentration detector transmits an electrical signal to the alarm, and the alarm gives an alarm to prompt the staff to replace the damaged dust removal bag 2.

[0035] Aiming at the problem that the installation and replacement process of the existing dust removal bag 2 is cumbersome, to improve the operation efficiency, first control the electric slider 102 to drive the upper side of the isolation cover 5 and the scraping ring 6 to move downward. The isolation cover 5 shrinks downward until it can no longer be compressed downward. At this time, the bottom of the dust removal bag 2 is completely exposed. At the same time, the isolation cover 5 is lower than the disc 20101 and no longer blocks the bottom of the dust removal bag 2. At this time, manually lift the blocking block 203 upward so that the blocking block 203 is away from the clamping ring 202. Then put the bag mouth of the dust removal bag 2 into the disc 20101 and pull it upward until the bottom of the dust removal bag 2 is completely attached to the disc 20101. At this time, the bag mouth of the dust removal bag 2 will cross the clamping ring 202. Then manually fold the bag mouth downward so that the bag mouth wraps the upper part of the clamping ring 202. As Figure 5 shown, then press the blocking block 203 downward to squeeze and block the bag mouth of the dust removal bag 2. At this time, the purified air flow in the dust removal bag 2 will be transported to the air outlet pipe 4 through the blocking block 203 and the connecting pipe 4001. Thus, the quick installation of the dust removal bag 2 is realized. When the installation of the dust removal bag 2 is completed, control the electric slider 102 to drive the upper side of the isolation cover 5 and the scraping ring 6 to move upward to return to the initial position.

[0036] Furthermore, when the unpurified air flow enters the ventilation hole 5002 of the isolation cover 5 through the air inlet hole 3001 of the air inlet ring 3, the joint position between the air inlet hole 3001 and the ventilation hole 5002 is sealed by the sealing ring 301. Thus, it is avoided that the air flow overflows through the gap between the air inlet ring 3 and the isolation cover 5, preventing the unpurified air flow from entering the interior of the purification equipment and improving the cleanliness of the interior of the purification equipment.

[0037] The above has introduced this application in detail. Specific examples are used in this article to elaborate on the principle and implementation mode of this application. The description of the above embodiments is only used to help understand the method and its core idea of this application; at the same time, for those of ordinary skill in the art, according to the idea of this application, there will be changes in the specific implementation mode and application scope. In summary, the content of this specification should not be construed as a limitation to this application.
