Description

Technical Field

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

[0002] An air compressor 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; they are mainly used in refrigerator compressors, air conditioning compressors, refrigeration compressors, oil field compressors, natural gas filling stations, rock drills, pneumatic tools, vehicle braking, door and window opening and closing, textile machinery, tire inflation, plastic machinery compressors, mining compressors, marine compressors, medical compressors, and sandblasting and painting.

[0003] Due to the presence of water vapor in the air, the compressed air will accumulate in the tank inside the compressor. The accumulated liquid will affect the use of the compressor. It is necessary to drain the water regularly through the drain pipe at the lower end of the compressor. The compressor can be used normally only after drainage.

[0004] However, since the air inside the compressor is compressed and has a very high pressure, the water discharged during drainage is discharged at high pressure, which can cause damage to the user's hands. In addition, most drainage pipes are connected to extension pipes during drainage, and the high-pressure water can easily break through the wall of the extension pipe or even cause it to fall off.

[0005] In order to solve the above problems, the present application proposes a compressor sewage discharge device. Utility Model Content

[0006] In view of the deficiencies in the prior art, the utility model provides a compressor sewage discharge device to at least solve one of the problems raised by the background technology.

[0007] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a compressor sewage discharge device, comprising a compressor body and a drain pipe arranged at the lower end of the compressor body, a pressure reducing assembly is arranged on the drain pipe, the pressure reducing assembly comprises a connecting pipe, an internal threaded opening is opened at the upper end of the connecting pipe, the internal threaded opening is threadedly connected to the outer wall of the drain pipe, a fixing piece is arranged inside the connecting pipe, a ball is rotatably connected to the end of the fixing piece, and a plurality of water outlets are opened at the lower end of the connecting pipe.

[0008] A further technical improvement of the utility model is that a placement groove is opened in the middle of the lower end of the inner wall of the connecting pipe, a spring is fixedly connected in the placement groove, and the upper end of the spring is fixedly connected to the lower end of the fixing piece.

[0009] A further technical improvement of the utility model is that a flow guide head is fixedly connected to the lower end of the connecting pipe, and the end of the flow guide head is conical.

[0010] A further technical improvement of the utility model is that a guide rod is fixedly connected to the middle of the lower end of the connecting pipe, and the lower end of the guide rod is arranged outside the lower end of the guide head.

[0011] A further technical improvement of the utility model is that a connecting thread line is provided on the outer side of the lower end of the guide head.

[0012] A further technical improvement of the utility model is that the water outlets are arranged at equal intervals.

[0013] The utility model provides a compressor sewage discharge device, which has the following beneficial effects:

[0014] This new type is applied to the compressor sewage discharge device. By setting up a pressure reducing component, it can dissipate the instantaneous pressure of the sprayed high-pressure water through the ball bearing, and then the water after the pressure is relieved flows out from the water outlet. The pressure of the discharged water is reduced compared with the original pressure, avoiding a large impact force on the user's hands or connecting pipes, and reducing the destructive force of the water sprayed inside the compressor body.

[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] See also Figure 1-3 A compressor sewage discharge device comprises a compressor body 1 and a drainage pipe 2 arranged at the lower end of the compressor body 1, a pressure reducing assembly is arranged on the drainage pipe 2, and the pressure reducing assembly comprises a connecting pipe 3, an internal threaded opening 4 is opened at the upper end of the connecting pipe 3, and the internal threaded opening 4 is threadedly connected to the outer wall of the drainage pipe 2, a fixing piece 8 is arranged inside the connecting pipe 3, and a ball 9 is rotatably connected to the end of the fixing piece 8, and a plurality of water outlets 5 are opened at the lower end of the connecting pipe 3.

[0022] Specific working principle and implementation method: a pressure reducing assembly is arranged on the drain pipe 2 at the lower end of the compressor body 1, the connecting pipe 3 is hollow, and an internal threaded opening 4 is opened at the upper end of the connecting pipe 3, and the connecting pipe 3 is connected to the outer thread of the drain pipe 2 through the internal threaded opening 4, so that it is convenient to disassemble the pressure reducing assembly as a whole, and a fixing part 8 is arranged inside the connecting pipe 3, and a ball 9 is rotatably connected to the upper end of the fixing part 8, and the water inside the compressor body 1 is sprayed out through the drain pipe 2, and the sprayed water contacts the ball 9. After the ball 9 encounters the sprayed water, it starts to rotate and discharges the water to the outside, and the water discharged to the outside flows out through the water outlet 5. The advantage of such a design is that the instantaneous pressure of the sprayed high-pressure water can be dissipated by the ball 9, and then the water after the pressure is dissipated flows out from the water outlet 5, and the pressure of the discharged water is reduced relative to the original pressure, so as to avoid causing a large impact force on the user's hands or the connecting pipe, and reduce the destructive force of the water sprayed out of the compressor body 1.

[0023] like Figure 3 As shown, a placement groove 6 is opened in the middle of the lower end of the inner wall of the connecting pipe 3, and a spring 7 is fixedly connected in the placement groove 6. The upper end of the spring 7 is fixedly connected to the lower end of the fixing member 8. After the fixing member 8 and the ball 9 are subjected to the pressure of the sprayed water, the impact force is resolved by the spring 7. The spring 7 can resolve the impact force, thereby reducing the impact destructive force of the sprayed water.

[0024] like Figure 3 As shown, the lower end of the connecting pipe 3 is fixedly connected with a guide head 10, the end of the guide head 10 is conical, and the inner side of the end of the guide head 10 is conical, which can prevent the sprayed water from being sprayed, and can gather and flow out the decompressed water, thereby facilitating the lower end to handle the sprayed water.

[0025] like Figure 3 As shown, a guide rod 11 is fixedly connected to the middle of the lower end of the connecting pipe 3, and the lower end of the guide rod 11 is arranged outside the lower end of the guide head 10. The guide rod 11 can increase the adhesion of the sprayed water, thereby allowing the sprayed water to gather in one place and reduce the splashing force of the sprayed water.

[0026] like Figure 3As shown, a connecting thread line 12 is provided on the outer side of the lower end of the guide head 10. By providing the connecting thread line 12 on the outer side of the lower end of the guide head 10, connecting pipes and processing equipment can be added to the lower end of the guide head 10, thereby increasing the versatility of the processing equipment.

[0027] like Figure 3 As shown, the water outlets 5 are arranged at equal intervals. Multiple water outlets 5 can increase the outflow of water. At the same time, the water outlets 5 are arranged at equal intervals to spray water evenly.

[0028] The above description is only a preferred embodiment of the present invention and does not constitute any form of limitation to the present invention. Although the present invention has been disclosed as a preferred embodiment as above, it is not intended to limit the present invention. Any technical personnel in this field can make some changes or modify the technical contents disclosed above into equivalent embodiments without departing from the scope of the technical solution of the present invention. However, any simple modification, equivalent change and modification made to the above embodiments based on the technical essence of the present invention without departing from the content of the technical solution of the present invention still fall within the scope of the technical solution of the present invention.
