Description

Technical Field

[0001] The utility model relates to the technical field of filtering devices, in particular to a high-pressure gas pipeline filtering device for a food workshop. Background Art

[0002] The high-pressure gas pipeline is the part connecting the compressor outlet and the condenser inlet, also known as the high-pressure exhaust pipe. The connecting pipelines from the condenser outlet to the liquid storage dryer, as well as the liquid storage dryer and the throttling element, are all high-pressure liquid pipes. The food workshop has extremely high requirements for cleanliness and hygiene. The high-pressure gas pipeline can be used to purge equipment, pipes and containers to effectively remove residues and pollutants and keep the production environment clean and sanitary. High-pressure gas may contain various impurities, such as particles, moisture, oil, etc. These impurities may cause blockage, corrosion or wear to the pipeline system, affecting the normal operation and performance of the system. The use of filtering devices can effectively remove these impurities and ensure the purity of the gas. At the current stage, the high-pressure gas pipeline filtering device has a single filtering method and poor filtering effect. It is impossible to perform multiple cycle filtering and is inconvenient to install and disassemble.

[0003] In order to solve the above problems, a utility model patent with publication number CN212974480U discloses a high-pressure gas pipeline filtering device, which can perform circulation filtering treatment on high-pressure gas, thereby improving the filtering treatment effect. A first pressure cover and a second pressure cover are respectively installed at both ends of the first filter tank and the second filter tank, and the first pressure cover and the second pressure cover are conveniently connected to the first filter tank and the second filter tank in a sealed manner through the sealing plugs on their inner sides, and ear racks are installed on one side of the first pressure cover and the second pressure cover, which are convenient for connection and fixation with the tapping seat, thereby facilitating installation and disassembly.

[0004] There are still some shortcomings in the use of the above-mentioned high-pressure gas pipeline filtering device. After the filtering device has been used for a long time, a large amount of particulate impurities will be adsorbed on the surface due to long-term filtration, causing the filter eyes to become clogged, thereby reducing the filtering effect. If it is not cleaned in time, it is easy to cause the filter element in the filtering device to be corroded by dirt for a long time, thereby causing damage, reducing the service life. The filter element is usually arranged on the inner side of the second protective net. After the filter element is disassembled, it is not convenient to quickly clean the filter element, which is more troublesome and leads to reduced cleaning efficiency. Utility Model Content
