Therefore, after a period of use, the compressor needs to be drained to remove the accumulated liquid.
[0003] Currently, the liquid inside the compressor is usually drained through a drain pipe located at the bottom of the compressor. However, because the compressor is under high pressure, the water pressure discharged from the drain pipe is also high, which can easily cause injury to workers. Utility Model Content

[0038] like Figure 1-6 As shown in this embodiment, the present invention provides a compressor draining device, including an inlet pipe 100, a pressure reducing component, and an outlet pipe 200.
[0039] The inlet end of the inlet pipe 100 is threadedly connected to the compressor's drain pipe for easy installation and disassembly of the entire drain device. The pressure-reducing assembly has an inlet and an outlet; the inlet of the pressure-reducing assembly is connected to the outlet end of the inlet pipe 100. The pressure-reducing assembly is used to reduce the pressure of the liquid, thereby reducing the liquid's flow velocity. The inlet end of the outlet pipe 200 is connected to the outlet end of the pressure-reducing assembly.
[0040] During use, the liquid accumulated in the compressor enters the inlet pipe 100 through the drain pipe, and then enters the pressure reducing component. Under the action of the pressure reducing component, the pressure of the fluid is reduced, thereby reducing the flow rate of the liquid.
[0041] like Figure 1-4 As shown, in this embodiment, the pressure reduction assembly includes a first housing 310 and a pressure reduction blade 320.
[0042] The first housing 310 has a hollow first inner cavity and a first liquid inlet and a first liquid outlet communicating with the first inner cavity. The first liquid inlet is connected to the liquid outlet end of the liquid inlet pipe 100, and the first liquid outlet is connected to the liquid inlet end of the liquid outlet pipe 200.
[0043] Specifically, such as Figure 1-4 As shown, the first housing 310 includes a first half-housing 311 and a first cover 312 that are interlocked and detachably connected. The inlet pipe 100 and the outlet pipe 200 are integrally formed with the first half-housing 311.
[0044] like Figure 1-4 As shown, in this embodiment, the first half-shell 311 and the first cover 312 are detachably connected by the first bolt 350.
[0045] The pressure-reducing blade 320 is rotatably disposed within the first inner cavity. Specifically, a rotating shaft 330 is disposed within the first housing 310, and the pressure-reducing blade 320 is rotatably connected to the first housing 310 via the rotating shaft 330.
[0046] Specifically, such as Figure 3-4 As shown, in this embodiment, the rotating shaft 330 is rotatably connected to the first housing 310, and the pressure-reducing blade 320 is fixedly connected to the rotating shaft 330.
[0047] like Figure 1-2 As shown, in this embodiment, the rotating shaft 330 is fixedly connected to the first housing 310, and the pressure-reducing blade 320 is rotatably connected to the rotating shaft 330.
[0048] During operation, the liquid entering from the first inlet impacts the pressure-reducing blade 320, driving the pressure-reducing blade 320 to rotate. The liquid impacts the pressure-reducing blade 320, and the pressure-reducing blade 320 applies a reaction force to the liquid, thereby reducing the liquid pressure and thus reducing the liquid flow rate.
[0049] Meanwhile, the rotating pressure-reducing blade 320 relieves some of the force exerted by the liquid on it, preventing damage from excessive pressure and thus extending its service life. Furthermore, the rotation of the pressure-reducing blade 320 prevents it from being subjected to force in only one point, further extending its service life.
[0050] like Figure 2 , 4As shown, in this embodiment, the pressure-reducing component further includes a damping structure. The damping structure is disposed at the rotation center of the pressure-reducing blade 320, and is used to increase the resistance encountered by the pressure-reducing blade 320 when it rotates. Specifically, in this embodiment, by setting the damping mechanism, the pressure-reducing blade 320 will only rotate when the external force it receives exceeds a preset value, thereby increasing the reaction force exerted by the pressure-reducing blade 320 on the liquid, and thus improving the pressure-reducing effect.
[0051] Specifically, the damping element 340 is made of silicone and is located at the rotation center of the pressure-reducing blade 320. The pressure-reducing blade 320 is interference-fitted with the first housing 310 through the damping element 340.
[0052] like Figure 4 As shown, in this embodiment, damping elements 340 are sleeved at both ends of the rotating shaft 330, and the two ends of the rotating shaft 330 are rotatably connected to the first housing 310 through the damping elements 340.
[0053] like Figure 2 As shown, the two ends of the rotating shaft 330 are fixedly connected to the first housing 310, the damping element 340 is coaxially sleeved on the rotating shaft 330, and the pressure-reducing blade 320 is rotatably connected to the rotating shaft 330 through the damping element 340.
[0054] like Figure 1 , 3 As shown, in this embodiment, the axis of the first liquid inlet is perpendicular to the axis of the first liquid outlet, so that the liquid entering the first housing 310 needs to be reversed in the first housing 310, thereby achieving the purpose of further improving the pressure reduction effect.
[0055] like Figure 5 , 6 As shown, in this embodiment, the step-down assembly includes a second housing 410 and a step-down element 420.
[0056] The second housing 410 has a hollow second inner cavity and a second liquid inlet and a second liquid outlet communicating with the second inner cavity. Specifically, the second housing 410 includes a second half-housing 411 and a second cover 412 that are interlocked and detachably connected. The liquid inlet pipe 100 and the liquid outlet pipe 200 are integrally formed with the second half-housing 411. The pressure reducing element 420 is detachably connected to the second cover 412.
[0057] like Figure 5 , 6 As shown, the second half-shell 411 and the second cover 412 are detachably connected by the second bolt 440. The pressure-reducing element 420 is detachably connected to the second cover 412 by the third bolt 450.
[0058] The voltage-reducing element 420 is cylindrical and is disposed in the second inner cavity. The outer side wall of the voltage-reducing element 420 is in contact with the inner side wall of the second inner cavity, and the outer side wall of the voltage-reducing element 420 is provided with a plurality of through-flow guide grooves 421. The side wall of the flow guide grooves 421 and the inner side wall of the second inner cavity form a flow channel.
[0059] During operation, the liquid entering from the second inlet impacts the pressure reducing element 420, and the pressure reducing element 420 applies a reaction force to the liquid, thereby reducing the liquid pressure and thus reducing the liquid flow rate.
[0060] like Figure 6 As shown, in this embodiment, a boss 422 is provided on the side of the pressure reducing element 420 facing the second liquid inlet, and a ball bearing 430 is provided on the side of the boss 422 facing the second liquid inlet. The diameter of the ball bearing 430 is larger than the diameter of the second liquid inlet so that the liquid entering from the second liquid inlet can impact the ball bearing 430.
[0061] During operation, the liquid entering through the second inlet impacts the ball bearing 430, driving it to rotate. The ball bearing 430 exerts a reaction force on the liquid, thereby reducing its pressure and flow rate. Simultaneously, the liquid flows downwards against the arc surface of the ball bearing 430, impacting the pressure-reducing element 420. The pressure-reducing element 420 then applies a force to the fluid, further reducing its pressure and flow rate, thus enhancing the pressure-reducing effect.
[0062] In addition, the rotation of the ball bearing 430 relieves some of the force exerted by the liquid, preventing it from being damaged by excessive pressure and thus extending its service life. Furthermore, the rotation of the ball bearing 430 prevents it from being subjected to force in only one point, further extending its service life.
[0063] like Figure 6 As shown, in this embodiment, a liquid storage tank 423 is provided at the bottom of the boss 422. During operation, after the liquid impacts the ball bearing 430, it enters the liquid storage tank 423. When the liquid storage tank 423 is full of liquid, the liquid flows along the side wall of the liquid storage tank 423 into the flow channel and finally flows out from the second liquid outlet. Furthermore, the liquid in the liquid storage tank 423 can improve the pressure reduction effect on the liquid.
[0064] In this embodiment, the present invention provides a compressor, including the compressor sewage discharge device described in any of the above embodiments.
[0065] Numerous specific details are set forth in this specification. However, it will be understood that embodiments of this invention may be practiced without these specific details. In some instances, well-known methods, structures, and techniques have not been shown in detail so as not to obscure the understanding of this specification.
[0066] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features.
