[0032] The driving assembly includes a slide rail 101, an electric slider 102 and a driving member 103; four slide rails 101 are fixed to the cover 1; each slide rail 101 is slidably connected to an electric slider 102, and each electric slider 102 is fixed to the upper side of the adjacent isolation cover 5, and the isolation cover 5 and the scraper ring 6 are driven by the electric slider 102 to move up and down, and the dust on the outer surface of the dust bag 2 is scraped and cleaned; four driving members 103 are fixed to the upper side of the cover 1, and the driving member 103 is a multi-stage electric push rod; the telescopic end of each driving member 103 is fixed to the adjacent injection pipe 7, and the injection pipe 7 is driven up and down by the driving member 103.

[0033] Each isolation cover 5 is configured to be in a truncated cone shape.

[0034] Each isolation cover 5 is made of corrosion-resistant material.

[0035] Each scraper ring 6 is configured to be curved on one side away from the dust bag 2 to reduce the friction between the scraper ring 6 and the dust, thereby preventing the scraped dust impurities from adhering to the scraper ring 6 to the greatest extent and affecting the cleaning effect of the scraper ring 6.

[0036] The annular diameter of the air injection pipe 7 is larger than the inner diameter of the dust removal bag 2 .

[0037] The working process of this embodiment is:

[0038] The working process of the existing purification device is as follows: first, start the external pump 1 and the external pump 2, and the unpurified airflow is transported to the intake ring 3 through the external pump 1, and then the airflow is transported to the space between the outer surface of the dust bag 2 and the inner wall of the isolation cover 5 through the air inlet hole 3001 of the intake ring 3, and then the suction force generated by the external pump 2 makes the airflow between the outer surface of the dust bag 2 and the inner wall of the isolation cover 5 pass through the dust bag 2 and enter the inner wall of the dust bag 2, so that the dust carried by the airflow is intercepted on the outer surface of the dust bag 2, thereby achieving purification of the airflow, and finally the airflow in the outlet pipe 4 is discharged into the atmosphere through the external pump 2.

[0039] In view of the limited internal space of the purification equipment, the existence of the isolation cover 5 makes it difficult for operators to clean and repair the equipment, and during the cleaning process, moist dust easily forms mud cakes on the outer surface of the dust bag 2, which is difficult to be completely cleaned by pulse airflow. The solution is as follows: when the purification equipment has been working for a period of time and the built-in dust bag 2 needs to be cleaned, when cleaning the first dust bag 2, close the solenoid valve on the air pipe between the first air intake ring 3 and the external pump 1, so that the unpurified gas no longer passes through the air intake ring 3 into the space between the first dust bag 2 and the isolation cover 5, and the solenoid valves connected to the other air intake rings 3 are opened normally, that is, the other dust bags 2 are working normally. At this time, the first There is no airflow inside the dust bag 2, and the electric slider 102 is controlled to drive the upper side of the first isolation cover 5 and the adjacent scraper ring 6 to move downward. The isolation cover 5 gradually shrinks downward, and the baffle 5003 gradually moves away from the extrusion rod 3002, and rotates upward under the action of the torsion spring, gradually fitting with the lower side of the vent 5002, thereby blocking the vent 5002, and the scraper ring 6 will scrape and clean the dust on the periphery of the dust bag 2. At the same time, start the external pump three, so that the airflow enters the jet pipe 7 through the telescopic tube, and is ejected to the outside of the dust bag 2 through the jet slot of the jet pipe 7, and then controls the driving part 103 to drive the jet pipe 7 to move downward synchronously with the scraper ring 6, and then in the jet pipe Under the impact of the airflow ejected by 7, the dust impurities adhered to the pores of the dust bag 2 are blown out, and the dust impurities adhered to the outer surface of the dust bag 2 are scraped and cleaned by the scraper ring 6, thereby preventing the moist dust impurities from adhering to the pores of the dust bag 2 during the cleaning of the scraper ring 6, and affecting the subsequent purification effect of the dust bag 2. At the same time, as the upper side of the isolation cover 5 moves downward, the air vent 5002 is blocked by the baffle 5003, thereby preventing the airflow ejected by the air jet pipe 7 from blowing the dust scraped by the scraper ring 6 into the interior of the equipment through the air vent 5002, causing the interior of the equipment to be polluted. Since the annular diameter of the air jet pipe 7 is larger than the inner diameter of the dust bag 2, the dust bag 2 adopts The elastically deformable material, when the jet pipe 7 moves downward, the contact portion of the dust bag 2 with the jet pipe 7 will bulge outward, and the dust bag 2 will be expanded outward through the jet pipe 7, thereby enlarging the pores on the dust bag 2, thereby improving the cleaning effect of the airflow of the jet pipe 7 on the dust. At the same time, under the expansion effect of the jet pipe 7, the dust bag 2 and the scraper ring 6 fit more closely, thereby further improving the cleaning effect of the scraper ring 6 on the dust bag 2. At the same time, when the operator needs to inspect the equipment, the electric slider 102 is controlled to drive the upper side of the isolation cover 5 and the scraper ring 6 to move downward, so that the isolation cover 5 is contracted, thereby increasing the operating space inside the purification equipment and improving the convenience of personnel operation.

[0040] When the first dust bag 2 is cleaned, turn off the external pump machine 3. Manual personnel only need to disassemble the disassembly and assembly part 5001 and collect and process the dust impurities scraped off the dust bag 2 in a unified manner, so as to prevent the dust from falling directly into the purification equipment. There is no need to perform additional cleaning inside the purification equipment, which reduces the cleaning cost. After the dust treatment is completed, the electric slider 102 and the driving part 103 are controlled to drive the upper side of the isolation cover 5, the scraper ring 6 and the injection pipe 7 to move upward 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 3001 of the intake ring 3 is connected to the air vent 5002 of the isolation cover 5. Then start the solenoid valve connected to the first intake ring 3 to restore the first dust bag 2 to the operating state, and then close the solenoid valve connected to the air pipe on the second intake ring 3, and repeat the above cleaning steps, thereby achieving non-stop cleaning and improving the cleaning efficiency of the equipment.

[0041] Taking into account that when the dust intercepted and filtered by the dust bag 2 is in a wet state, over time, the dust adhered to the outer surface of the dust bag 2 will gradually slide down and accumulate, resulting in excessive dust impurities gathering at the bottom of the dust bag 2, affecting the normal contraction of the isolation cover 5. By setting the isolation cover 5 to a truncated cone shape, sufficient space is reserved between the lower side of the isolation cover 5 and the dust bag 2, thereby preventing excessive dust accumulation from hindering the contraction of the isolation cover 5.

[0042] Example 2

[0043] On the basis of Example 1, Figures 1-6 As shown, each connecting pipe 4001 is equipped with a dust concentration detector for real-time monitoring of the dust concentration flowing in the connecting pipe 4001 , thereby determining whether the dust bag 2 is damaged.

[0044] It also includes a quick-release assembly, which includes a connecting rod 201, a retaining ring 202 and a blocking block 203; four connecting rods 201 are fixed to the cover 1; a retaining ring 202 is fixed to each air intake ring 3; each connecting pipe 4001 is connected to a blocking block 203; each connecting pipe 4001 is made of elastic deformation material.

[0045] Each connecting rod 201 passes through the blocking block 203, and the blocking block 203 and the connecting rod 201 adopt a damping sliding connection method to increase 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 airflow and maximizing the stability of the blocking block 203 during the operation of the dust removal bag 2.

[0046] A sealing ring 301 is also included; each air inlet 3001 is fixedly connected to a sealing ring 301 .

[0047] The working process of this embodiment is:

[0048] Taking into account that the dust bag 2 may be damaged, aged or perforated after long-term use, thereby affecting the purification effect, in order to solve the above problem, the dust concentration in the connecting pipe 4001 is monitored in real time by a dust concentration detector. When the dust bag 2 is damaged, aged or perforated, the unfiltered dust will directly enter the connecting pipe 4001 with the purified gas, causing the dust concentration in the connecting pipe 4001 to increase significantly, indicating that the dust bag 2 has been damaged. Then the dust concentration detector transmits an electrical signal to the alarm, and the alarm sounds an alarm, prompting the staff to replace the damaged dust bag 2.

[0049] In view of the problem that the installation and replacement process of the existing dust bag 2 is cumbersome, in order to improve the operating efficiency, the electric slider 102 is first controlled to drive the upper side of the isolation cover 5 and the scraper ring 6 to move downward, and the isolation cover 5 contracts downward until the isolation cover 5 can no longer be compressed downward. At this time, the bottom of the dust bag 2 is completely exposed, and the isolation cover 5 is lower than the disc 20101, and no longer blocks the bottom of the dust bag 2. At this time, the blocking block 203 is manually lifted upward to keep the blocking block 203 away from the snap ring 202, and the bag opening of the dust bag 2 is inserted into the disc 20101 and pulled upward until the bottom of the dust bag 2 is completely fitted with the disc 20101. At this time, the bag opening of the dust bag 2 will pass over the snap ring 202, and then the bag opening is manually folded downward so that the bag opening wraps the upper part of the snap ring 202. Figure 5 As shown, press the blocking block 203 downwards so that the blocking block 203 squeezes and blocks the bag opening of the dust bag 2. At this time, the purified airflow in the dust bag 2 will be transported to the air outlet pipe 4 through the blocking block 203 and the connecting pipe 4001, thereby realizing the quick installation of the dust bag 2. When the dust bag 2 is installed, control the electric slider 102 to drive the upper side of the isolation cover 5 and the scraper ring 6 to move upward and return to the initial position.

[0050] Furthermore, when the unpurified airflow enters the air vent 5002 of the isolation cover 5 through the air inlet hole 3001 of the air inlet ring 3, the joint between the air inlet hole 3001 and the air vent 5002 is sealed by the sealing ring 301, thereby preventing the airflow from overflowing through the gap where the air inlet ring 3 contacts the isolation cover 5, preventing the unpurified airflow from entering the interior of the purification equipment, and improving the cleanliness of the interior of the purification equipment.
