In this embodiment, when the compressed gas of the air compressor main body 1 enters the feeding pipeline 22, the gas-oil mixture enters the accommodating groove 215 of the pipeline anti-blocking ball 28, the pipeline anti-blocking ball 28 can be pushed to rotate by the accommodating groove 215, the position of the pipeline anti-blocking ball 28 is limited by the vertical strut 29 in the hollow pipeline 24, the rotation of the pipeline anti-blocking ball 28 can drive the bevel gear 210 to rotate through the vertical strut 29, the rotation of the bevel gear 210 can push the driven gear 261 to rotate, the operation of the air extraction assembly 26 is powered, so that the feeding and the gas-oil separation can be performed simultaneously, the decomposition efficiency of oil and harmful gas can be avoided, and friction can be continuously generated between the pipeline anti-blocking ball 28 and the inner wall of the feeding pipeline 22 in the rotating process of the pipeline anti-blocking ball 28, so that the oil on the inner wall of the feeding pipeline 22 is scraped, and the blocking probability of the pipeline is reduced as much as possible.
The application method and the working principle of the device are as follows: the air compressor main body 1 pressurizes and sends the gas to be treated into the double-end pipeline 6 through the communication pipeline 5, so that the oil-gas mixture firstly enters the oil-gas separation device 2, the oil enters the oil decomposition device main body 3 after being treated by the oil-gas separation device 2, and the gas enters the gas decomposition device main body 4 to finish the catalytic oxidation decomposition treatment.
Meanwhile, in the process, the oil-gas mixture pushes the pipeline anti-blocking ball 28 in the feeding pipeline 22 to rotate, the bevel gear 210 can be driven to rotate by the rotation of the pipeline anti-blocking ball 28 through the vertical supporting rod 29, the driven gear 261 can be driven to rotate by the rotation of the bevel gear 210, the butt joint rod 263 can be directly driven by the rotation of the driven gear 261 through the switching sleeve 262, the partition plate 264 can keep the same speed as the butt joint rod 263 to rotate, one transmission supporting rod 265 can be pushed to enter the transfer pipeline 212 in the process of rotating the partition plate 264, the other transmission supporting rod 265 is pulled out from the transfer pipeline 212, and the transmission supporting rod 265 entering the transfer pipeline 212 can push the plugging block 267 in the transfer pipeline 212 to move.
In addition, because of the existence of the filling gasket 268, the blocking block 267 penetrating into the transfer pipeline 212 can prevent air from entering and simultaneously push air in the oil precipitation tank 21 to enter into another transfer pipeline 212, and at the moment, the transmission support rod 265 in the transfer pipeline 212 is in a carried-away state, the filling gasket 268 loses contact with the transfer pipeline 212, so that air can enter into the transfer pipeline 212, when the partition plate 264 rotates to the second circle, the blocking block 267 containing air in the transfer pipeline 212 can move inwards again, and the air in the transfer pipeline 212 is extruded into the air supply pipeline 27, so that air extraction and transportation are completed.
The bent pipe 211 and the air supply pipeline 27 are connected in the transfer pipeline 212, so that the moving route of air can be greatly shortened, the condition of air backflow can be effectively avoided due to the existence of the one-way valve 213, the opposite direction can ensure that air can only flow unidirectionally, and separated oil can enter the oil decomposition device main body 3 through the oil conveying pipeline 23, so that oil-gas separation is realized.
Although the present invention has been described with reference to the foregoing embodiments, it will be apparent to those skilled in the art that modifications may be made to the embodiments described, or equivalents may be substituted for elements thereof, and any modifications, equivalents, improvements and changes may be made without departing from the spirit and principles of the present invention.
