Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of air compressors, and more specifically relates to a hydrophobic structure. Background Art
[0002] When the air compressor compresses the air, the temperature and humidity of the air will rise. When the compressed air passes through the cooler, the temperature will gradually drop, and the humidity will also change. When the temperature drops below the dew point, water vapor will condense into liquid water to form condensed water. If the condensed water is not discharged in time, it will have a serious impact on the stable operation of the air compressor over time. At present, there are two ways to drain the condensed water. 1. Use an electronic drain valve, that is, use the liquid level to control the action of the solenoid valve to automatically drain the water. 2. Mechanical steam trap, the mechanical steam trap is directly connected to the cooler drain pipe, and the float rises or falls through the change of the liquid level. The float drives the lever to make the valve disc leave or contact the valve seat to open the drainage and close the steam barrier. The first drainage method is more expensive, a set of solenoid valves costs several thousand yuan, and the solenoid valve is easily damaged when it is in contact with water for a long time. The liquid level probe also needs to be replaced regularly, and it is easy to get blocked when there is rust inside. The second drainage method produces a lot of rust in the cooler, which can easily cause the mechanical drain valve to become clogged. Therefore, it often needs to be dismantled for maintenance and cleaning. Excessive accumulation of rust may cause blockage and inability to drain water or the drain cannot be automatically closed. Most manufacturers directly discharge the condensed water and air from the cooler due to the above reasons.
[0003] In the prior art, there is a technology named "drain valve structure" and published as "CN206669303U", which includes an upper valve body and a lower valve body arranged at the lower end of the upper valve body, the upper valve body is provided with a valve body inlet and an exhaust port, a protective plate is provided inside the upper valve body, the protective plate is provided with a through hole near the side wall of the upper valve body, a sewage outlet is provided at the lower end of the lower valve body, a water outlet is provided at the connection between the upper valve body and the lower valve body, a control component for controlling the opening and closing of the water outlet is provided at the water outlet, the water outlet is symmetrically arranged with two, the control component includes a float and two valve flaps, the two valve flaps are respectively pivotally connected to the two water outlets through a rotating shaft, and the float is respectively connected to the two valve flaps through a pulling rope. The drainage process is stable and the use effect is good. However, this technology does not involve the technical problems and technical solutions of the present application. Utility Model Content
[0004] The technical problem to be solved by the utility model is: in view of the deficiencies in the prior art, a mechanical drain valve with a simple structure is provided to achieve long-term stable operation without being blocked by impurities, and finally to achieve zero-loss automatic drainage of the cooler of the air compressor, without wasting compressed air, saving energy, and achieving reliable and stable operation of the air compressor, and an economical and practical drain structure.
[0005] To solve the above-mentioned technical problems, the technical solution adopted by the utility model is:
[0006] The utility model is a drain structure. A cooler is connected to a water tank through a water inlet pipe. The drain pipe extends into the water tank. The height of the port of the drain pipe extending into the water tank is higher than the bottom surface of the water tank. A mechanical drain valve is installed on the drain pipe.
[0007] The drain pipe comprises a horizontal section and a vertical section. The vertical section extends to the inside of the water storage tank, and the upper end of the vertical section is a port.
[0008] The water inlet and the water inlet of the water inlet pipe are connected with the cooler and the water inlet is connected with the water storage tank.
[0009] The height of the bottom surface of the water storage tank is lower than the height of the drainage outlet of the water inlet pipe.
[0010] The upper part of the water storage tank is connected to an exhaust pipe, and an exhaust valve is installed on the exhaust pipe.
[0011] A sewage pipe is installed on the bottom surface of the water storage tank, and a sewage valve is installed on the sewage pipe.
[0012] The inner wall and outer surface of the drain pipe are respectively provided with a galvanized layer.
[0013] The water inlet pipe is arranged to form an acute angle with the horizontal line.
[0014] A water inlet valve is arranged on the water inlet pipe.
[0015] The technical solution of the utility model is adopted, and the working principle and beneficial effects are as follows:
[0016] The drain structure described in the utility model is that the cooler is connected to the water tank through the water inlet pipe, and the condensed water generated by the cooler enters the water tank. The drain pipe extends into the water tank, and the height of the port of the drain pipe extending into the water tank is higher than the bottom of the water tank. A mechanical drain valve is installed on the drain pipe. The specific working principle and working process of the above structure are: when the cooler (air compressor cooler) generates condensed water, the compressed air and water enter the water tank through the water inlet pipe. At this time, the upper part of the water tank is air, and the lower part is condensed water. After the water level of the condensed water slowly rises, the water level rises to a height that exceeds the port of the drain pipe extending into the water tank. Then, the condensed water enters the drain pipe from the port, and then the condensed water is automatically drained through the mechanical drain valve. Therefore, the advantages of the above structure over the simple electronic drainage device are: 1. Simple structure and low price; 2. Not easy to damage, and basically no spare parts need to be replaced for 3-5 years. The advantage of the above structure over the existing mechanical steam trap is that the previous mechanical steam traps were directly connected to the drain pipe of the cooler, which easily caused the mechanical steam trap to be blocked. Because there is water in the air compressor cooler for a long time, there is a lot of rust inside. After entering the water tank, the height of the drain pipe is certain (the port height can be 80mm higher than the bottom of the water tank, etc.). In this way, because the rust has weight, it will not enter the port with the condensed water, so that the rust is stored at the bottom of the water tank, effectively preventing the rust from entering the mechanical steam trap, ensuring the reliability of the mechanical steam trap. The reliability of the overall structure is greatly increased, and there is no blockage phenomenon; it does not need to be disassembled for maintenance and cleaning, saving labor costs.

DETAILED DESCRIPTION
[0020] The following is a detailed description of the embodiments of the present invention, such as the shapes, structures, positions and connection relationships of the components involved, the functions and working principles of the components, etc., by referring to the accompanying drawings:
[0021] As attached Figure 1As shown, the utility model is a drain structure, the cooler 1 is connected to the water tank 3 through the water inlet pipe 7, the drain pipe 6 extends into the water tank 3, the drain pipe 6 extends to the port 8 inside the water tank 3 at a height higher than the bottom surface of the water tank 3, and a mechanical drain valve 15 is installed on the drain pipe 6. The above structure proposes an improved technical solution to the deficiencies in the prior art. When the structure is set, the cooler 1 is connected to the water tank 3 through the water inlet pipe 7, so that the condensed water generated by the cooler 1 enters the water tank 3, the drain pipe 6 extends into the water tank 3, the drain pipe 6 extends to the port 8 inside the water tank 3 at a height higher than the bottom surface of the water tank 3, and a mechanical drain valve 15 is installed on the drain pipe 6. The specific working principle and working process of the above structure are: when the cooler (air compressor cooler) 1 generates condensed water, the compressed air and water enter the water tank 3 through the water inlet pipe 7. At this time, the upper part of the water tank 3 is air, and the lower part is condensed water. After the water level of the condensed water slowly rises, the water level rises to a height exceeding the port 8 extending from the drain pipe 6 to the inside of the water tank 3. Then, the condensed water enters the drain pipe 6 from the port 8, and then the condensed water is automatically drained through the mechanical drain valve 15. Therefore, the advantages of the above structure over the simple electronic drainage device are: 1. Simple structure and low price; 2. Not easy to damage, and basically no spare parts need to be replaced for 3-5 years. The advantages of the above structure over the existing mechanical drain valves are: the previous mechanical drain valves were directly connected to the drain pipe of the cooler, which easily caused the mechanical drain valve to be blocked. Because there is water in the air compressor cooler for a long time, there is a lot of rust inside. After entering the water tank, because the height of the drain pipe 6 is a certain height (the height of the port 8 can be 80mm higher than the bottom of the water tank, etc.), the rust has weight and will not enter the port with the condensed water, so the rust is stored at the bottom of the water tank, effectively preventing the rust from entering the mechanical steam trap and ensuring the reliability of the mechanical steam trap. In this way, the reliability of the overall structure is greatly increased, and there is no blockage phenomenon; there is no need to dismantle it for maintenance and cleaning, saving labor costs. The drain structure described in the utility model has a simple structure, realizes the long-term stable operation of the mechanical steam trap, and does not have the phenomenon of being blocked by impurities. Finally, the air compressor cooler can achieve zero-loss automatic drainage, without wasting compressed air, saving energy consumption, and realizing reliable and stable operation of the air compressor, which is economical and practical.
[0022] The drain pipe 6 includes a horizontal section 9 and a vertical section 10, the vertical section 10 extends to the inside of the water storage tank 3, and the upper end of the vertical section 10 is a port 8. In the above structure, the horizontal section 9 and the vertical section 10 are an integrated structure, and the horizontal section 9 and the vertical section 10 are L-shaped structures. The upper end of the vertical section 10 is the port 8, so that the vertical section 10 of the drain pipe has a certain height in the water storage tank 3. Because rust has weight, it will not enter the port with condensed water, so that the rust is stored at the bottom of the water storage tank, preventing the rust from entering the mechanical drain valve, and ensuring the reliability of the mechanical drain valve.
[0023] The water inlet 7 has a drain port 11 and a water inlet 12, wherein the drain port 11 is connected to the cooler 1, and the water inlet 12 is connected to the water storage tank 3. In the above structure, the cooler 1 is connected to the water storage tank 3 through the water inlet pipe 7, so that the condensed water generated in the cooler is conveniently and reliably transported to the water storage tank for storage, and when the height of the condensed water in the water storage tank 3 is higher than the height of the port 8, automatic discharge is achieved.
[0024] The height of the bottom surface of the water storage tank 3 is lower than the height of the drain port 11 of the water inlet pipe 7. The above structure allows condensed water and impurities such as rust to smoothly enter the water storage tank from the cooler through the water inlet pipe. When the condensed water is stored in the water storage tank and the storage height is higher than the height of the port, the condensed water enters the drain pipe from the port and is then discharged through the mechanical drain valve.
[0025] The upper part of the water storage tank 3 is connected to the exhaust pipe 13, and the exhaust valve 4 is installed on the exhaust pipe 13. In the above structure, further, the absolute humidity of the air in summer is greater than that in winter, and the cooler 1 will produce a large amount of condensed water. At this time, the exhaust valve 4 on the exhaust pipe at the upper part of the water storage tank can be slightly opened for drainage, so as to accelerate the speed of condensed water entering the water storage tank 3 and quickly discharge the condensed water inside the cooler 1. A drain pipe 14 is installed on the bottom surface of the water storage tank 3, and a drain valve 5 is installed on the drain pipe 14. In the above structure, a drain valve 5 is set on the drain pipe at the bottom of the water storage tank, and manual drainage can be performed. After running for a period of time, too much rust accumulates inside the water storage tank 3 and needs to be discharged in time. The drain valve 5 is opened for drainage, and drainage is generally performed once every three months.
[0026] The inner wall and outer surface of the drain pipe 6 are respectively provided with a galvanized layer. With the above structure, the galvanized layer effectively improves the rust-proof ability of the drain pipe 6 and effectively improves the service life of the drain pipe 6.
[0027] The water inlet pipe 7 is arranged to have an acute angle with the horizontal line. In the above structure, the angle can be 10°, so that water and impurities such as rust can enter the water storage tank more smoothly. The water inlet pipe 7 is provided with a water inlet valve 2. The water inlet valve realizes the on-off control of the water inlet pipe.
[0028] The drain structure described in the utility model, the cooler 1 is connected to the water tank 3 through the water inlet pipe 7, and the condensed water generated by the cooler 1 enters the water tank 3, the drain pipe 6 extends into the water tank 3, the drain pipe 6 extends to the port 8 inside the water tank 3, and the height is higher than the bottom surface of the water tank 3, and the mechanical drain valve 15 is installed on the drain pipe 6. The specific working principle and working process of the above structure are: when the cooler (air compressor cooler) 1 generates condensed water, the compressed air and water enter the water tank 3 through the water inlet pipe 7, at this time, the upper part of the water tank 3 is air, and the lower part is condensed water. After the water level of the condensed water rises slowly, the water level rises to a height exceeding the port 8 extending from the drain pipe 6 to the inside of the water tank 3, then the condensed water enters the drain pipe 6 from the port 8, and then the condensed water is automatically drained through the mechanical drain valve 15. Therefore, the advantages of the above structure compared with the simple electronic drainage device are: 1. Simple structure and low price; 2. Not easy to damage, basically no spare parts need to be replaced for 3-5 years. The advantage of the above structure over the existing mechanical steam trap is that the previous mechanical steam traps were directly connected to the drain pipe of the cooler, which easily caused the mechanical steam trap to be blocked. Because there is water in the air compressor cooler for a long time, there is a lot of rust inside. After entering the water storage tank, because the height of the drain pipe is a certain height (the height of port 8 can be 80mm higher than the bottom of the water storage tank, etc.), the rust has weight and will not enter the port with the condensed water, so that the rust is stored at the bottom of the water storage tank, effectively preventing the rust from entering the mechanical steam trap and ensuring the reliability of the mechanical steam trap. In this way, the reliability of the overall structure is greatly increased, and there is no blockage phenomenon; there is no need to dismantle it for maintenance and cleaning, saving labor costs.
[0029] The above is an exemplary description of the utility model in conjunction with the accompanying drawings. It is obvious that the specific implementation of the utility model is not limited to the above-mentioned method. As long as various improvements are made using the method concept and technical solution of the utility model, or the concept and technical solution of the utility model are directly applied to other occasions without improvement, they are all within the protection scope of the utility model.
