Description

Technical Field

[0001] The utility model belongs to the technical field of gas filtration, in particular to an air inlet filtration mechanism of high-pressure paint spraying equipment. Background Art

[0002] High-pressure paint spraying equipment is a device that can pressurize paint to a high-pressure state and release the pressure through a nozzle to form atomization, thereby forming a coating on the surface of an object. It usually uses high-pressure gas to spray the paint.

[0003] Most of the existing high-pressure paint spraying equipment has an air intake filtration mechanism, which directly filters impurities in the gas through the filter, thereby reducing the impurities in the gas. However, most of them are unable to clean the filter structure during operation. When the filter has been working for a long time, there will be a lot of dust on its outer surface. At this time, manual maintenance and cleaning are required. Moreover, the filter only relies on a single filtration of the gas, and the filtering effect is not ideal. In order to avoid poor painting effect, we propose an air intake filtration mechanism for high-pressure paint spraying equipment. Utility Model Content

[0039] A specific application of this embodiment is:

[0040] When in use, put the filter element 121 into the top of the filter cartridge 1, and the bottom of the filter element 121 will be plugged into the support plate 131 through the positioning ring 211, and the cross groove at the bottom of the filter element 121 will be plugged into the cross block 313, so that the filter element 121 is positioned and placed, and then the sealing gasket 122 is put on the top of the filter element 121, and the sealing gasket 2 15 is put on the top of the filter cartridge 1, and then the top cover 11 is threadedly connected to the filter cartridge 1 through the threaded mounting ring 113, and the top cover 11 is installed. At this time, the outer ring 123 will be put on from the outside of the filter element 121, and when the bottom of the top cover 11 contacts the top of the filter cartridge 1, the sealing gasket 122 and the sealing gasket 2 15 are in contact with the bottom of the top cover 11, thereby playing a sealing role, and at the same time, the stabilizing ring 114 is in contact with the inner side of the top of the filter element 121 Plug-in improves the stability of the filter element 121. This method is convenient for installing the filter element 121. When it is necessary to filter the gas, the air inlet pipe 111 is connected to the air pipe to allow the gas to enter the filter cartridge 1 through the air inlet pipe 111. After the high-pressure gas contacts the fan blades 125, the fan blades 125 will be pushed, so that the fan blades 125 drive the rotating ring 124 to rotate on the outer ring 123. When the fan blades 125 rotate at high speed, suction can be generated, thereby sucking the gas into the filter cartridge 1, which can play a role in assisting air intake and can make the gas surround the filter cartridge 1, so as to be evenly filtered through the filter element 121. The gas entering the filter cartridge 1 will be filtered by the filter element 121, and the filtered gas will be discharged from the exhaust pipe 112 to complete the filtration. This method improves the filtering effect. The effect of gas on paint is greatly reduced, and the adhesion effect of paint to objects is better, which improves the quality of painting. When the filter element 121 is used for a long time, more particles and dust will adhere to the surface, causing the filter element 121 to be blocked, affecting the gas process. At this time, the micro motor 312 is started to drive the rotating shaft 311 to rotate, and the support plate 131 will drive the filter element 121 to rotate through the cross block 313. The setting of the cross block 313 will not affect the installation and disassembly of the filter element 121, and can smoothly drive the filter element 121 to rotate. During the rotation process, the filter element 121 will throw out the particles on the surface under the action of centrifugal force. At the same time, because the scraper 142 is in close contact with the surface of the filter element 121 under the elastic action of the spring 144, the filter element 121 rotates The scraper rod 142 can scrape off the particles on the surface of the filter element 121, improve the cleaning effect, thereby increasing the service life of the filter element 121 and improving the filtering effect of the filter element 121. The processed particles and dust will adhere to the inner wall of the filter cartridge 1 and fall downward. The conical plate 13 is used to guide the particles and dust to be discharged to the bottom of the conical plate 13 through the leakage groove 132. When the particles need to be cleaned, the threaded sealing cover 2 is rotated counterclockwise to be removed, and the bottom of the filter cartridge 1 can be opened for cleaning. After cleaning, the threaded sealing cover 2 is connected to the threaded fixing ring 21 and rotated clockwise to seal the bottom of the filter cartridge 1. When the filter element 121 needs to be replaced later, the top cover 11 is removed, and then the filter element 121 is pulled upward and taken out for replacement.
