[0002] As an indispensable equipment in the modern industrial field, compressors have shown a growing trend in both domestic and foreign markets in recent years. With the development of industry, the demand for air compressors will continue to grow. Some countries have also introduced relevant policies and regulations to promote environmental protection and energy conservation, which also stimulated the development of the compressor market;

[0003] During the high-speed operation of the existing compressor, the piston rod reciprocates back and forth, causing the related packing to be damaged, resulting in a small amount of oil tank lubricating oil being brought into the middle body box. If it is not removed in time, the middle body oil level will be overfilled, causing the related compressor seals and packing to be more seriously damaged and greatly reducing the service life;

[0004] At the same time, a small amount of lubricating oil will be brought into the piston cylinder, causing a liquid hammer accident and serious damage to the compressor. Of course, it will also bring huge property losses to the company and the risk of production equipment stopping at any time, greatly reducing the safe operation coefficient of the equipment. At the same time, if the lubricating oil is directly discharged, it will cause a large amount of lubricating oil waste and environmental pollution. Utility Model Content

DETAILED DESCRIPTION

[0018] The present invention is further described in detail below in conjunction with the accompanying drawings and specific implementations:

[0019] like Figure 1 As shown, a centralized recovery system for lubricating oil in a compressor middle body includes a compressor body 1, which is mainly composed of a cylinder cavity 2, a piston rod 3, and a middle body box 4. The cylinder cavity 2 and the middle body box 4 are respectively connected and fixed to a recovery box 7 through pipelines. A filter component is provided in the recovery box 7 for uniformly filtering the lubricating oil discharged from the middle body box 4.

[0020] like Figure 2As shown, the filter assembly includes a drive motor 13 fixed on the top end cover of the recovery box 7, the output shaft of the drive motor 13 is synchronously driven and connected with a rotating shaft 14, the rotating shaft 14 extends downward through the end cover of the recovery box 7 and is connected to a number of connecting rods 15 at the end, and a filter cartridge 16 is hinged on the corresponding connecting rod 15, and a replaceable filter cotton is arranged on the inner side of the filter cartridge 16.

[0021] like Figure 2 As shown, a plurality of connecting rods 15 are evenly arranged in an array along the circumference of the rotating shaft 14 .

[0022] like Figure 2 As shown, the filter cartridge 16 is opened at the upper end and is located below the oil inlet 19 of the recovery box 7 .

[0023] like Figure 2 As shown, a plurality of filter holes 17 are evenly formed on the side wall of the filter cartridge 16, and the diameter of the filter holes 17 is 2-5 mm.

[0024] like Figure 2 As shown, the inner side wall of the recovery box 7 is provided with a lever 18 for causing the filter cartridge 16 to swing back and forth when the filter cartridge 16 rotates.

[0025] like Figure 1 As shown, a check valve 5 and a flow meter 6 are installed on the pipeline connecting the upper part of the recovery box 7 and the middle box 4, an oil injection pump 11 and a control valve 11 are installed on the pipeline connecting the recovery box 7 and the cylinder cavity 2, and a drain pipe 9 is provided on one side of the recovery box 7, and a flame arrester 8 is installed on the drain pipe 9.

[0026] The implementation principle of a centralized recovery system for lubricating oil in a compressor according to an embodiment of the present application is as follows:

[0027] When the compressor body 1 is working, the piston rod 3 reciprocates in the cylinder cavity 2. During the operation, the lubricating oil will be brought into the middle body box 4. When the oil level in the middle body box 4 is high, it is ready to be discharged;

[0028] When discharging and recovering the oil in the middle body box 4, open the check valve 5 to discharge the lubricating oil in the middle body box 4. The discharged lubricating oil will flow along the oil pipeline through the flow meter 6 and flow into the filter cartridge 16 from the oil inlet 19. When the lubricating oil flowing through reaches the preset value of the flow meter 6 (set according to the on-site conditions), close the check valve 5. After closing the check valve 5 and the lubricating oil in the oil pipeline all enters the filter cartridge 16, start the drive motor 13 again. The drive motor 13 will drive the filter cartridge 16 hinged on the connecting rod 15 along The rotating shaft 14 rotates in the circumferential direction. When the filter cartridge 16 rotates to contact the lever 18, the filter cartridge 16 will tilt along the axis of the rotating shaft of the connecting rod 15. At the same time, the tilting angle will not cause the lubricating oil inside the filter cartridge 16 to spill out. After the filter cartridge 16 passes through the lever 18, the center of gravity of the filter cartridge 16 is offset, causing the filter cartridge 16 to swing back and forth. During the swinging process, the lubricating oil inside the filter cartridge 16 will evenly fall from the filter hole 17 into the recovery box 7, thereby achieving the effect of recovery and filtration.

[0029] After the lubricating oil is discharged from the middle body box 4, the lubricating oil in the corresponding cylinder cavity 2 will be lacking. At this time, the control valve 11 connected to the oil pipe of the oil filling port 12 is opened, and the oil filling pump 10 is started at the same time to inject the filtered lubricating oil in the recovery box 7 into the cylinder cavity 2, thereby ensuring that the parts inside the cylinder cavity 2 are fully lubricated.
