Description

Technical Field

[0001] The utility model relates to the technical field of electrophoretic coating production, in particular to a high-efficiency dust removal bag for electrophoretic coating production. Background Art

[0002] Electrophoretic coatings produce waste gas during the production process. The waste gas contains a large amount of organic solvents and heavy metal substances. If it is discharged directly, it will not only pollute the atmospheric environment, but also cause serious pollution to the surrounding soil and water sources, endangering the health of the food chain. The waste gas also has a strong pungent odor. Long-term exposure to such an environment will have a negative impact on the health of workers, such as irritation to the eyes, skin and respiratory tract, and even affect the central nervous system and internal organs.

[0003] After using for a period of time, traditional dust removal bags need to be removed and replaced. When removing and replacing, the device needs to be shut down and wait. During the shutdown and waiting process, the device cannot continue to filter the exhaust gas generated by the electrophoretic coating production, which will undoubtedly affect the overall filtration efficiency of the device.

[0004] In view of this, this application is hereby filed. Utility Model Content

[0022] By adopting the above design, when filtering exhaust gas, only the first bag 201 or the second bag 202 will be used. After one of the first bag 201 or the second bag 202 has been used for a certain period of time, the connecting shaft 204 can be driven to rotate by starting the stepper motor 203, thereby swapping the positions of the first bag 201 and the second bag 202, so that the unused first bag 201 or the second bag 202 placed in the replacement box 2 is replaced with the other one to be cleaned, thereby quickly completing the replacement of the bag, and then the dust collector 1 can be quickly put into production again without delaying the filtering process of the exhaust gas.

[0023] refer to Figure 2-4 Furthermore, a cleaning component 3 is provided in the replacement box 2, and the cleaning component 3 includes an atomizing nozzle 301, which is arranged on the inner wall of the replacement box 2 near the air outlet 103, and the atomizing nozzle 301 is located at the center of the inner wall. A water pipe passing through the replacement box 2 is arranged on the back of the atomizing nozzle 301. The cleaning component 3 also includes a fan 302, which is arranged on the inner wall of the replacement box 2 near the air outlet 103. There are two fans 302, which are respectively located above and below the atomizing nozzle 301.

[0024] By adopting the above design, the first cloth bag 201 or the second cloth bag 202 entering the replacement box 2 after replacement is completed can be sprayed with water from the air outlet direction through the atomizing nozzle 301, thereby flushing down the particles or solvent adsorbed thereon, and the fan 302 blows air on both sides to assist the atomizing nozzle 301 to flush down the wetted particles, and after the flushing is completed, it can continue to run to air dry.

[0025] refer to Figure 3 and Figure 4 Furthermore, a trigger block 205 is provided on the first cloth bag 201 and the second cloth bag 202, a switch 304 is provided in the replacement box 2, a chamfer is provided on the switch 304, the switch 304 is electrically connected to the atomizing nozzle 301 and the fan 302, the switch 304 is a trigger-type, delayed, timing switch 304, and its delay time is greater than the time required for a single step of the stepping motor 203, and after the switch 304 is triggered and the atomizing nozzle 301 and the fan 302 are started, the closing time of the fan 302 is later than that of the atomizing nozzle 301.

[0026] By adopting the above design, after the positions of the first cloth bag 201 and the second cloth bag 202 are swapped, the atomizing nozzle 301 and the fan 302 can be automatically started to clean the cloth bag entering the replacement box 2, so that after the cloth bag is exchanged, the lower cloth bag can be automatically cleaned and dried.

[0027] In addition, the bottom surface of the replacement box 2 is tilted, and the side located at the air inlet 104 is the lowest end. The side of the bottom surface of the replacement box 2 close to the air inlet 104 is connected to the drainage pipe 303.

[0028] By adopting the above design, after the atomizing nozzle 301 and the fan 302 flush the pollutants on the bag, the mixture with the water flow will automatically enter the drainage pipe 303 due to the chamfer of the bottom surface of the replacement box 2, and then be transported to a designated place through the drainage pipe 303 for centralized treatment and recycling.

[0029] Working principle:

[0030] When in use, connect the air inlet 104 to the exhaust gas tightening pipe, start the fan 102 to start filtering, and the exhaust gas will enter from the air inlet 104, be filtered by the first bag 201 or the second bag 202, and be discharged through the air outlet 103.

[0031] After a certain period of use, the positions of the first cloth bag 201 and the second cloth bag 202 can be swapped by starting the stepper motor 203. During the swapping process, the trigger block 205 will trigger the switch 304 again. After the switch 304 is triggered, the switch 304 will start the atomizing nozzle 301 and the fan 302 after the swap is completed. The swapped cloth bags will be rinsed and blown from their air outlet direction, and the mixture of pollutants and water will enter the drainage pipe 303 along the chamfer for centralized recycling. After a certain period of flushing and blowing, the atomizing nozzle 301 turns off the fan 302 and continues to blow to dry the cloth bags. After drying, the fan 302 automatically turns off, thereby automatically completing the cleaning of the replaced cloth bags.
