Description

Technical Field

[0001] The utility model relates to the field of sewage discharge devices, in particular to a sewage discharge device for an air compressor. Background Art

[0002] An air compressor is an air compressor, which is a device used to compress gas. The structure of an air compressor is similar to that of a water pump. Most air compressors are reciprocating piston type, with rotating blades or rotating screws. An air compressor compresses air to a high pressure state through a compressor, and then stores the high-pressure gas in a gas tank. When compressed air is needed, the compressor releases the gas in the gas tank and transports it to the place where it is needed through a pipeline. An air compressor is an important mechanical equipment, which is widely used in various industrial fields, such as manufacturing, construction, food processing, etc., providing stable and reliable compressed air power for these fields.

[0003] In the prior art, when the ambient humidity is high or there is too much water in the air, the gas output by the air compressor will contain water vapor. The water vapor may condense into liquid water during the compression process and come into contact with the metal hardware inside the compressor, thereby forming rusty water inside the air compressor. Therefore, the rusty water needs to be discharged regularly. However, the existing air compressors do not have the function of filtering and treating sewage, so the staff will directly open the drain valve when discharging sewage to discharge the internal rusty water directly into the external environment, which not only pollutes the environment, but also is not conducive to the environmentally friendly use of the air compressor.

[0022] like Figure 3As shown, a connecting ring 10 is fixedly installed on the left wall of the cylinder 9, and a first external thread 11 is provided on the outer wall of the connecting ring 10, and the first external thread 11 is threadedly connected with the first internal thread 8. A sealing ring 12 is also sleeved on the outer wall of the connecting ring 10, and a drain port 13 is fixedly installed on the right wall of the cylinder 9. The cylinder 9 is rotated so that the first external thread 11 on the outer wall of the connecting ring 10 is threadedly connected with the first internal thread 8, so that the cylinder 9 can be installed and fixed on the cylinder cover 5, and the cylinder 9 can be easily unscrewed for disassembly and cleaning later. After installation, the sealing ring 12 sleeved on the outside of the connecting ring 10 can ensure the sealing of the cylinder 9 and the cylinder cover 5 after connection, so as to prevent sewage from seeping out of the cylinder 9;

[0023] like Figure 3 As shown, a first fixing ring 14 is fixedly installed on the inner right end wall of the cylinder 9, and a second external thread 15 is provided on the outer wall of the first fixing ring 14. A second fixing ring 16 is also fixedly installed on the inner right end wall of the cylinder 9 and outside the first fixing ring 14, and a third external thread 17 is provided on the outer wall of the second fixing ring 16. The second external thread 15 on the outer wall of the first fixing ring 14 is used to facilitate the connection of the fine filter cartridge 18, and the third external thread 17 on the outer wall of the second fixing ring 16 is used to facilitate the connection of the coarse filter cartridge 21.

[0024] like Figure 3 As shown, a second internal thread 19 is provided on the right side of the inner wall of the fine filter cartridge 18, and the second internal thread 19 is threadedly connected with the second external thread 15. A plurality of fine filter holes 20 are also provided on the outer wall of the fine filter cartridge 18. The fine filter cartridge 18 is rotated to make the second internal thread 19 and the second external thread 15 threadedly connected together, and the fine filter cartridge 18 can be installed and fixed on the first fixing ring 14 and placed inside the cylinder 9. The fine filter cartridge 18 can be subsequently unscrewed from the cylinder 9 for cleaning to prevent the fine filter holes 20 from being blocked after long-term use, and the smaller rust and impurities in the sewage entering the cylinder 9 can be filtered and blocked through the plurality of fine filter holes 20 on the outer wall of the fine filter cartridge 18.

[0025] like Figure 3 As shown, a third internal thread 22 is provided on the right side of the inner wall of the coarse filter cartridge 21, and the third internal thread 22 is threadedly connected with the third external thread 17, and a plurality of coarse filter holes 23 are also provided on the outer wall of the coarse filter cartridge 21. After the coarse filter cartridge 21 is rotated to thread the third internal thread 22 with the third external thread 17, the coarse filter cartridge 21 can be installed and fixed on the second fixing ring 16 and placed inside the cylinder 9 and outside the fine filter cartridge 18, and the coarse filter cartridge 21 can be easily unscrewed from the cylinder 9 for cleaning later to prevent the coarse filter holes 23 from being blocked after long-term use, and the larger rust and impurities in the sewage entering the cylinder 9 can be filtered and blocked in advance through the plurality of coarse filter holes 23 on the outer wall of the fine filter cartridge 18.

[0026] It should be noted that the utility model is a sewage discharge device for an air compressor. When the valve 3 is opened to allow the sewage with rust and impurities inside the air compressor body 1 to be discharged through the sewage outlet 2 for sewage discharge, the sewage discharged through the sewage outlet 2 will enter the cylinder 9 fixedly installed on the right side of the cylinder cover 5 from the connecting pipe 7 on the left side of the cylinder cover 5 through the water inlet pipe 6 connected to the valve 3. After the sewage enters the cylinder 9, the larger rust and impurities in the sewage will be filtered and blocked by a plurality of coarse filter holes 23 opened on the outer wall of the coarse filter cylinder 21 installed inside the cylinder 9, so that the larger rust and impurities are intercepted and filtered inside the cylinder 9. After the sewage enters the fine filter cylinder 18 through the coarse filter holes 23, the fine filter cylinder 18 installed in the cylinder 9 and located inside the coarse filter cylinder 21 will further filter and block the smaller rust and impurities in the sewage through a plurality of fine filter holes 20 opened on the outer wall, so that the smaller rust and impurities in the sewage will be filtered and blocked by the fine filter holes 20 opened on the outer wall, so that the smaller rust and impurities in the sewage will be filtered and blocked by the fine filter holes 23. Rust and impurities are intercepted inside the cylinder 9. Finally, the filtered and purified sewage will be discharged through the drain port 13 on the right side wall of the cylinder 9, so that the sewage is double filtered when the air compressor body 1 is discharged. This can not only avoid the sewage after the air compressor body 1 is discharged from polluting the environment, but also is conducive to the environmentally friendly use of the air compressor body 1. At the same time, in order to ensure the filtering effect of the sewage discharge filtering mechanism 4 on the sewage under long-term use, the cylinder 9 can be regularly unscrewed from the cylinder cover 5, and then the coarse filter cartridge 21 and the fine filter cartridge 18 can be unscrewed from the inside of the cylinder 9 in turn, so as to facilitate the cleaning of impurities filtered out of the cylinder 9 and the cleaning of the coarse filter cartridge 21 and the fine filter cartridge 18. By cleaning the coarse filter cartridge 21 and the fine filter cartridge 18, it can be prevented that the impurities cause clogging of the coarse filter holes 23 and the fine filter holes 20 after long-term use, resulting in poor filtering effect.
