DETAILED DESCRIPTION

[0019] In order to more clearly explain the overall concept of the present application, the following will be described in detail with reference to the accompanying drawings.

[0020] As Figs. 1-3 shown, the embodiment of the present application proposes a cold storage variable frequency screw compressor motor, which comprises a compressor motor body 1, two support plates 2 are installed at the bottom of the compressor motor body 1, a bottom plate 3 is fixedly installed at the bottom of each of the two support plates 2, and an oil separation barrel 15 is fixedly arranged at the top of the bottom plate 3;

[0021] The inner wall of the oil separation bucket 15 is provided with a scraping mechanism, and the scraping mechanism comprises a motor 8, a rotating shaft 9, a horizontal plate 10, a fixed rod 11, a scraper 12 and a leakage bucket 13. The inner wall of the oil separation bucket 15 is provided with the leakage bucket 13. The top end of the oil separation bucket 15 is fixedly installed with the motor 8. The output shaft of the motor 8 is fixedly installed with the rotating shaft 9 which penetrates and extends into the oil separation bucket 15. The bottom end of the rotating shaft 9 is fixedly installed with the horizontal plate 10. The bottom of the horizontal plate 10 is fixedly installed with the fixed rod 11. The bottom end of the fixed rod 11 is fixedly installed with the scraper 12 which is connected with the leakage bucket 13.

[0022] Specifically, the inner wall of the oil separation bucket 15 is fixedly installed with an annular fixed plate 14. The annular fixed plate 14 is fixed with the leakage bucket 13 through threaded nails. The oil and gas are separated through the oil separation bucket 15. The annular fixed plate 14 is fixed with the leakage bucket 13.

[0023] Specifically, the top end of the oil separation bucket 15 is fixedly installed with the gas outlet pipe 7. The gas generated by the oil separation bucket 15 is discharged through the gas outlet pipe 7.

[0024] Specifically, the outer circle of the oil separation bucket 15 is fixedly installed with the oil guide pipe 6. The oil at the bottom of the oil separation bucket 15 is discharged through the oil guide pipe 6.

[0025] Specifically, the outer circle of the compressor motor body 1 is fixedly installed with the conveying pipe 4. The other end of the conveying pipe 4 is fixedly connected with the oil separation bucket 15. The air and oil in the compressor motor body 1 are conveyed into the oil separation bucket 15 through the conveying pipe 4.

[0026] Specifically, the outer circle of the conveying pipe 4 is rotatably connected with the check valve 5. The check valve 5 controls the conveying pipe 4 to avoid backflow of oil and gas.

[0027] Working principle: When the compressor motor body 1 works, the air is compressed. The air and oil are conveyed into the oil separation bucket 15 through the conveying pipe 4. After passing through the leakage bucket 13 in the oil separation bucket 15, the oil drops to the bottom and the gas floats on the top. Then the gas is discharged through the gas outlet pipe 7, and the excess oil is discharged through the oil guide pipe 6. After a long time of use, the inner wall of the leakage bucket 13 will stick to oil stains. At this time, the motor 8 is started to drive the rotating shaft 9 to rotate, which drives the horizontal plate 10 to rotate. The scraper 12 is driven to move along the inner wall of the leakage bucket 13 through the fixed rod 11. At this time, the oil stains adhered to the inner wall of the leakage bucket 13 can be scraped off, avoiding the oil stains from blocking the gaps on the leakage bucket 13.
