[0024] Example 1

[0025] The utility model designs a condensate recovery device for a diaphragm compressor, which comprises a box body 10 and a buffer mechanism 20.

[0026] Specifically, the two ends of the box body 10 are respectively provided with an inlet pipe 11 and an outlet pipe 12, and the inlet pipe 11 is connected to the condenser of the diaphragm compressor through a flange plate, and is used to introduce the waste liquid containing gas in the condenser of the diaphragm compressor into the box body 10. The outlet pipe 12 is used to discharge the liquid in the box body 10, and the outlet pipe 12 is also installed with an outlet valve.

[0027] An exhaust port 13 is also provided on the top surface of the box body 10 near one end of the outlet pipe 12, and a filter screen (not shown) is installed on the exhaust port 13 toward one end of the box body to intercept liquid mixed in the gas. When applied to a hydrogen compressor, the exhaust port 13 is open (i.e., not connected to a gas storage tank), and a small amount of hydrogen escaping through the exhaust port 13 can be directly discharged into the environment. When applied to a compressor with a gas such as carbon dioxide, nitrogen or helium as a gas source, a gas storage tank 14 can be connected to the exhaust port 13 to temporarily hold or store the escaping gas. The gas storage tank 14 is provided with a pressure gauge 141, an exhaust valve 142 and a vent valve 143. Among them, the pressure gauge 141 is used to detect the pressure in the gas storage tank 14 in real time, and the exhaust valve 142 is used to cooperate with the pressure gauge 141 to adjust the pressure of the gas storage tank 14 to prevent the pressure from exceeding the standard, and can also be used to transport the gas in the gas storage tank 14 to other containers or equipment.

[0028] The buffer mechanism 20 includes a connecting frame 21 and a buffer plate 22. The two ends of the top of the connecting frame 21 are mounted on the side walls of the box body 10. Specifically, the top of the connecting frame 21 is provided with an integrally connected tube body 211, a rotating shaft 212 is installed through the tube body 211, and the two ends of the rotating shaft 212 are rotatably mounted on the side walls of the box body 10. The two ends of the rotating shaft 212 are located between the tube body 211 and the box body wall on the corresponding side and are also sleeved with a torsion spring 213. The two ends of the torsion spring 213 are fixedly connected to the end face of the tube body 211 on the corresponding side and the side wall of the box body 10, respectively.

[0029] The buffer plate 22 is installed on the vertical part of the connecting frame 21 and on the side facing the inlet pipe 11 through the buffer element 23. Specifically, the buffer element 23 includes a support frame 231, a guide rod 232 and a compression spring 233. The support frame 231 is a rectangular structure with one end open, and the two sides of the open end are installed on the two sides of the connecting frame 21. There are two support frames 231, which are respectively located at the top and bottom of the vertical part of the connecting frame 21. One end of the guide rod 232 is provided with a limit block. The end of the guide rod 232 without the limit block passes through the support frame 231 and is connected to the buffer plate 22. The compression spring 233 is sleeved on the guide rod 232. The support frame 231 is provided with a hole for the guide rod 232 to pass through and slide. The guide rod 232 plays the role of connecting the buffer plate 22 with the connecting frame 21 on the one hand, and is used for the installation and guidance of the compression spring 233 on the other hand.

[0030] The number of compression springs 233 located at the top of the vertical part of the connecting frame 21 is 2. The number of compression springs 233 located at the bottom of the vertical part of the connecting frame 21 is 4. By designing that the number of lower compression springs is greater than that of upper compression springs, the bottom of the buffer plate 22 has a higher impact resistance and buffering capacity.

[0031] The inlet pipe 11 is opposite to the lower part of the buffer plate 22. Specifically, the vertical distance from the axis of the inlet pipe 11 to the bottom end of the buffer plate is 1 / 4 to 1 / 3 of the height of the buffer plate.

[0032] The design of the buffer mechanism 20 can achieve a double buffering effect. Specifically, when the waste liquid containing gas in the condenser enters the box body 10 from the inlet pipe 11 at a relatively high pressure, due to the design of the position of the inlet pipe 11, the ejected liquid directly acts on the lower part of the buffer plate 22. At this time, the lower part of the buffer plate 22 moves outward under the action of pressure, so that the compression spring 233 is compressed. At the same time, the compression spring 233 buffers the impact force of the waste liquid to reduce the speed of the waste liquid, so that the waste liquid flows downward along the plate surface of the buffer plate 22 and is finally discharged from the outlet pipe 12 of the box body 10. If the impact force of the sprayed liquid is greater, the compression spring 233 is further compressed until the bottom of the connecting frame 21 is also moved to the right, and the tube body 211 at the top of the connecting frame 21 is driven to rotate along the rotating shaft 212. At this time, the end of the torsion spring 213 connected to the tube body 211 also rotates, causing the torsion spring 213 to deform. Due to the force of the torsion spring 213, the connecting frame 21 and the buffer plate 22 can be driven to further buffer the impact force of the waste liquid, thereby effectively reducing the impact force of the waste gas and playing a double buffering role. Through the action of the buffer mechanism 20 and the box 10, it is possible to effectively prevent the waste liquid from splashing and polluting the environment.

[0033] In the above process, when the waste liquid mixed with gas collides with the buffer plate 22, due to the different specific gravities of gas and liquid, the gas will bend and escape from the liquid, and finally escape from the box 10 from the exhaust port 13; the liquid will flow downward along the plate surface of the buffer plate 22, gather and exit the box from the outlet pipe 12.

[0034] In addition, the size of the buffer plate 22 is greater than or equal to the size of the vertical part of the connecting frame 21, and the height and width of the buffer plate 22 are smaller than the width and height of the box body 10, and the distance from the bottom edge of the buffer plate to the bottom surface of the box body 10 is 1 / 5 to 1 / 3 of the height of the box body, so that the waste liquid buffered by the buffer plate can converge and gather in the box body from the gap between the buffer plate 22 and the two sides and bottom of the box body.

[0035] The utility model discloses a condensate recovery device for a diaphragm compressor. Through the design of a box body and a buffer mechanism therein, on the one hand, it can effectively buffer the waste liquid sprayed by high pressure and prevent it from splashing into the environment, and on the other hand, it can effectively allow the gas mixed in the waste liquid to escape and separate in the waste liquid.

Any equivalent structure or equivalent process transformation made by using the contents of the specification and drawings of the present invention, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
