Description
Technical Field
[0001] This utility model relates to the field of air compressor drainage technology, and in particular to an automatic air compressor drainage device. Background Technology
[0002] An air compressor is a device used to compress gas. Similar in construction to a water pump, most air compressors are reciprocating piston, rotary vane, or rotary screw types. However, existing air compressors often fail to effectively filter air, and liquefied water tends to accumulate inside, resulting in water containing impurities and oil. Currently, various air compressor drainage systems exist, but some problems remain. For example, air and water are easily discharged together during drainage, leading to internal pressure loss and increased energy consumption. Furthermore, the discharged water contains oil and impurities, causing environmental pollution if directly released. Utility Model Content

[0024] To enable those skilled in the art to better understand the technical solutions of this utility model, the technical solutions in the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings.
[0025] Example 1:
[0026] See Figure 1-3An automatic drainage device for an air compressor includes a horizontally arranged drain pipe 1, a drain tank 2 at the drain end of the drain pipe 1, and a T-junction 11 connected to the drain pipe 1. A cap 21 seals the upper end of the drain tank 2, and the lower end of the drain tank 2 is a closed hemispherical shape. The outer wall of the cap 21 has external threads that connect with internal threads on the inner wall of the upper end of the drain tank 2. A water inlet 211 is located in the middle of the cap 21 and is integrally connected to a water inlet connector 212. The external thread of the water inlet connector 212 is threadedly and sealed to the internal thread of one of the interfaces of the T-junction 11, facilitating disassembly. A horizontal first baffle 22 is installed inside the drainage tank 2. The first baffle 22 is sealed to the inner wall of the drainage tank 2 on all four sides. A guide hole 23 is provided in the middle of the first baffle 22. A guide rod 24 passes through the guide hole 23 and is clearance-fitted with the guide hole 23. The guide rod 24 can be vertically guided relative to the guide hole 23. A first float 25 is fixedly connected to the lower end of the guide rod 24. A spring 26 is sleeved on the outer wall of the guide rod 24. The spring 26 is a compression spring. The upper end of the spring 26 is elastically fixedly connected to the first baffle 22 and the lower end is elastically fixedly connected to the first float 25. Multiple drainage holes 27 are arranged circumferentially around the guide hole 23. A horizontal second baffle 3 is installed below the first float 25. The second baffle 3 is sealed to the drain tank 2 on all four sides. A vertical overflow pipe 31 is installed in the middle of the second baffle 3. The overflow pipe 31 is used to automatically overflow liquid above the overflow pipe 31 into the overflow pipe 31. The lower end of the overflow pipe 31 is connected to the water outlet 32 provided on the second baffle 3. An annular screen plate 33 is installed on the first baffle 3. The side wall of the annular screen plate 33 is arranged with filter holes in a circumferential array. The annular screen plate 33 is used to filter impurities before entering the annular screen plate 33. A diverter block 34 is provided at the upper end of the annular screen plate 33. The diverter block 34 is cone-shaped. The conical surface of 4 facilitates the dispersion of liquid around the first partition plate 3, and makes it easy for the liquid to enter the interior of the annular sieve plate 33 evenly. The bottom of the drain tank 2 is provided with a drain port and a drain valve 213. The drain tank 2 stores the discharged water at the bottom. The lower side wall of the drain tank 2 is provided with a dosing port 217. The dosing port 217 facilitates the addition of flocculant to the liquid stored at the lower end of the drain tank 2, preventing the direct discharge of oil and grease from the air compressor and causing environmental pollution. The first float ball 25 floats to close or open the overflow port of the overflow pipe 31, which can prevent the air compressor from leaking during the drainage process and realize automatic drainage of the air compressor.
[0027] In this embodiment, see Figure 2 Preferably, a heating plate 4 is provided at the bottom of the second partition 3. The heating plate 4 can heat the liquid on the second partition 3 to prevent the liquid from freezing in a low-temperature environment and causing blockage.
[0028] In this embodiment, see Figure 1The drain pipe 1 is connected to the drain port 131 of the air compressor 13 through the elbow joint 12. The drain pipe 1 is equipped with a regulating valve 5. The valve 5 facilitates the control of the opening and closing of the drain pipe 1, so that the cleaning liquid can enter the drain tank 2 completely and not enter the air compressor 13 when cleaning the drain tank 2.
[0029] In this embodiment, see Figure 2 A movable rod 28 is inserted into each drain hole 27, and a second float 29 is installed at the upper end of each movable rod 28.
[0030] As an improved real-time method in this embodiment, see [link to relevant documentation]. Figure 2 An annular groove 221 is provided along the circumferential direction on the outer edge of the first partition plate 22. A discharge port is provided on the side wall of the annular groove 221 and connected to a discharge pipe 222. A discharge control valve 223 is provided on the discharge pipe 222. Impurities contained in the liquid discharged from the air compressor can be precipitated through the annular groove 221, and impurities intercepted by the annular screen plate 33 can be collected and discharged to the outside through the discharge port into the discharge pipe 222.
[0031] In this embodiment, see Figure 2 The lower side wall of the drainage tank 2 is provided with an exhaust port and connected to an exhaust pipe 214. The side wall of the drainage tank 2 is provided with a dosing tank 215. The dosing tank 215 is connected to the dosing port 217 through an infusion pipe 216. An electromagnetic flow valve is provided on the infusion pipe 216. Flocculant is prepared in the dosing tank 215 and then introduced into the drainage tank 2 through the infusion pipe 216 to degrade the oil in the water.
[0032] In this embodiment, preferably, see [reference needed]. Figure 1 , 2 The upper outer wall of the drain tank 2 is provided with an external hexagon 201, which makes it easy to use a wrench to clamp the external hexagon and fasten the drain tank 2 to the tee connector 11.
[0033] In this embodiment, preferably, see [reference needed]. Figure 2 The upper end of the drain hole 27 is a conical hole, which makes it easier for the second float ball 29 to enter the drain hole 27 more smoothly when it is not draining, so as to block the drain hole 27.
[0034] In this embodiment, preferably, see [reference needed]. Figure 2 , 3 The overflow port at the upper end of the overflow pipe 31 is flared. A groove is provided around the end face of the overflow port of the overflow pipe 31 in the circumferential direction. A sealing ring 231 is provided in the groove. The first float 25 can fit with the sealing ring 231 to seal the overflow port of the overflow pipe 31 when there is no buoyancy, thus preventing the gas from the air compressor 13 from being discharged from the overflow port.
[0035] In this embodiment, see Figure 1 The end of drain pipe 1 is sealed with a pipe plug.
[0036] As can be seen from the above technical solution, during use, water in the air compressor 13 is discharged into the drain pipe 1 through the drain outlet 131, and then introduced into the drain tank 2 through the inlet 211 via the three-way connector 11. The water is then dispersed around the first partition 3 by the diverter block 34, and then passes through the filter holes of the annular screen plate 33 into the annular screen plate 33, causing the second float ball 29 to float up, opening the drain hole 27, and then entering between the first partition plate 3 and the second partition plate 3. When the water level rises above the overflow port of the overflow pipe 31, the buoyancy of the first float ball 25 is greater than the elastic force of the spring 26 and the sum of the weight of the first float ball 25 and the guide rod 24. As the water level above the first partition plate 3 continues to rise, the floating height of the first float ball 25 increases, and the gap between the first float ball 25 and the overflow port of the overflow pipe 31 increases. The drainage speed is increased. At the same time, under the water level blockage, the air in the air compressor will not enter the overflow port of the overflow pipe 31. When the water level drops to the overflow port of the overflow pipe 31, the first float ball 25 loses its buoyancy and, during the spring 26's recovery of elasticity, blocks the overflow port of the overflow pipe 31 again, preventing the air in the air compressor from entering the overflow port of the overflow pipe 31. The water remaining on the first baffle 3 acts as a seal for the overflow port of the overflow pipe 31. The water entering the overflow pipe 31 enters the bottom cavity of the drain tank 2. The flocculant prepared in the dosing tank 215 is introduced into the bottom of the drain tank 2 through the infusion pipe 216, mixes with the water discharged from the air compressor, degrades the oil and purifies the water. Then, the drain valve 213 at the bottom of the drain tank 2 is controlled by the controller to discharge the water from the drain port.
[0037] When it is necessary to clean the interior, close the valve 5 on the drain pipe 1, then remove the plug at the end of the drain pipe 1 and connect the cleaning fluid supply pipe. The cleaning fluid enters the drain tank 2 to clean the internal components. During the cleaning process, the impurities accumulated in the annular groove 221 are discharged to the outside through the impurity discharge port into the impurity discharge pipe 222.

[0039] It should be understood that this utility model is not limited to the precise structure described above and shown in the accompanying drawings, and various modifications and changes can be made without departing from its scope. The embodiments of this utility model described above do not constitute a limitation on the scope of protection of this utility model.
