Description

Technical Field

[0001] The utility model relates to the technical field of air compression structures, in particular to a compressed air device for a gas distribution center of a whole plant. Background Art

[0002] Air compressor is an important industrial equipment used to compress gas and provide gas source.

[0003] The area around the air machine should be kept clean during operation to prevent the motor from inhaling dust. Usually a filter structure is set at the air intake of the air machine.

[0004] However, during use, the existing air compressor filter dust removal structure needs to be manually disassembled and cleaned regularly, and the disassembly and assembly steps are cumbersome, resulting in low cleaning efficiency of the filter.

[0005] For this reason, we propose a compressed air device for the gas distribution center of the whole plant to solve the existing problems. Utility Model Content

[0006] The utility model aims to solve the problems existing in the background technology and proposes a compressed air device for the gas distribution center of the whole plant.

[0007] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a compressed air device for the gas distribution center of the whole plant, comprising an air compressor body and an annular shell, wherein an air intake pipe and an air supply pipe are respectively arranged on the air compressor body, the annular shell is fixed at the end of the air intake pipe, a filter plate is movably arranged in the annular shell through a disassembly assembly component, an air inlet is opened on the air intake pipe, a recoil pipe is installed at the air inlet, the recoil pipe is interconnected with the inside of the annular shell through the air intake pipe, and the recoil pipe is interconnected with the air supply pipe through a hose structure.

[0008] Preferably, a switch valve is installed on the air intake pipe, the air inlet of the air intake pipe is located between the switch valve and the annular shell, and a flow valve is provided on the recoil pipe.

[0009] Preferably, the disassembly assembly is composed of a ring cover, a retaining ring and a ring frame;

[0010] The retaining ring is installed on the inner wall of the annular shell by bolts, the annular frame is installed on the outer annular surface of the filter plate, and the ring cover is threadedly installed on the annular shell.

[0011] Preferably, the ring frame is placed between the ring cover and the retaining ring, and two sides of the ring frame are squeezed and positioned by the ring cover and the retaining ring respectively, and rubber sealing rings are provided at the contact positions of the two sides of the ring frame with the ring cover and the retaining ring respectively.

[0012] Preferably, the outer wall of the annular shell is provided with a thread matched with the annular cover, and the inner wall thread of the annular cover is meshed with the outer wall thread of the annular shell.

[0013] Preferably, the lower surface of the air compressor body is provided with supporting feet, there are two supporting feet in total, and the positions of the two supporting feet are distributed in a rectangular array on the lower surface of the air compressor body.

[0014] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0015] During the use of the utility model, after the air compressor body works and sucks air through the air intake pipe for pressurization, the compressed air is discharged through the air delivery pipe. When the filter plate needs to be cleaned, the recoil pipe is opened and the air intake pipe is closed. Then, the compressed air flow output in the air delivery pipe enters the air intake pipe through the recoil pipe and then rushes into the space between the ring shell and the inner surface of the filter plate, thereby recoil-flushing the impurities attached to the outside of the filter plate, so that the filter plate can be self-cleaned without disassembly.

[0016] Furthermore, when the filter plate needs to be disassembled for replacement, the ring cover can be unscrewed to remove the filter plate. The utility model utilizes the output air source of the air compressor itself to perform self-cleaning operations on the filter plate without disassembling it, does not require an additional power source, and through structural coordination, the filter plate can be easily disassembled, assembled and replaced.
