AI Technical Summary
During long-term operation, the screw air compressor leaks oil due to wear and aging of seals, resulting in lubricating oil not being able to effectively cover the components, causing aggravation of wear and mechanical failure, and oil leakage pollutes the environment.
An oil leakage return screw air compressor is designed. The leaking oil is collected by setting up a lead pipe and a recovery pipe, and the air inlet is used to return it to the air compressor, and impurities are filtered through the filter element to prevent re-entry, and the air inlet port and the output port are added to achieve secondary compression of the gas and increase the air pressure.

Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of air compressors, and relates to a screw air compressor, in particular to an oil leakage return screw air compressor. Background Technique
[0002] A screw air compressor is an air compressor that increases the pressure of gas through the mechanical movement of the main and driven screws. It has a wide range of applications in the industrial field and has the advantages of high reliability, simple operation and maintenance, good dynamic balance, and strong adaptability.
[0003] Sealing components inside the main body of the screw air compressor, such as gaskets and sealing rings, will be worn and aged during long-term operation, resulting in a decline in sealing performance and thus causing oil leakage.
[0004] The operation of the screw air compressor depends on lubricating oil to maintain the lubrication and cooling of components. If oil leakage occurs, the lubricating oil will not be able to effectively cover all components that need lubrication, resulting in increased wear of these components due to lack of lubrication. In severe cases, it may damage the compressor and even cause mechanical failures. Summary of the Invention
[0005] The purpose of the utility model is to provide an oil leakage return screw air compressor with efficient filtration for the above problems existing in the prior art.
[0006] The purpose of the utility model can be achieved by the following technical solutions: An oil leakage return screw air compressor, characterized in that it includes an air compressor main body provided with an air inlet end and an air outlet end. An air inlet A and an air inlet B are provided on the air inlet end. An upwardly arranged air inlet pipe is provided on the air inlet A. A lead-out pipe is provided on the air compressor main body. A recovery pipe is provided on the air inlet pipe. One end of the recovery pipe is clamped to the lead-out pipe. A detachable filter element is provided on the recovery pipe. One end of the air compressor main body is provided with an end cover. A plurality of compression screws are provided inside the air compressor main body. An input end is provided on the compression screw, and this input end is arranged outside the end cover.
[0007] In the above-mentioned oil leakage return screw air compressor, a return port and an output port are provided on the air outlet end. An output air pipe is provided on the output port.
[0008] In the above-mentioned oil leakage return screw air compressor, an auxiliary air inlet pipe is provided on the air inlet B, and an external connection part is provided at the end of the auxiliary air inlet pipe.
[0009] In the above-mentioned oil leakage return screw air compressor, a bridging pipe is provided between the return port and the auxiliary air inlet pipe.
[0010] Compared with the prior art, an oil leakage return screw air compressor is provided with a lead-out pipe and a recovery pipe to recover the leaked oil inside the air compressor, and the oil is returned to the air compressor through the air inlet, preventing the internal components from being worn due to oil leakage. At the same time, reducing leakage can reduce environmental pollution. Multiple air inlets and outlets can compress the gas twice, increasing the air pressure of the gas output from the output pipe.

After the internal oil leaks, it is collected and flows out through the lead-out pipe 8. The leaked oil enters the air inlet pipe 6 along the recovery pipe 7, and the oil is recovered through the air inlet. When the oil enters the recovery pipe 7, the impurities in the oil precipitate and are filtered by the filter element 18, preventing the impurities from flowing back into the air compressor.
