Description

Technical Field

[0001] This application relates to the technical field of air compressors, and particularly to an automatic drainage device for an air compressor. Background Art

[0002] The full name of an air compressor is an air compressor, which can provide air source for pneumatic components. An air compressor is a device used to compress gas. The air compressor pumps external air into a pressure tank for compression, and uses the compressed air to provide driving force for the device. Since there is moisture in the air, during the compression process, water will separate from the air and accumulate at the bottom of the air storage tank. For safe operation, it is necessary to drain the air storage tank regularly.

[0003] In the patent with the publication number CN216842147U, an air compressor drainage device is disclosed. This device can only drain the water in the air compressor. If the water is directly drained into the sewer pipe, it is rather wasteful. Utility Model Content

[0004] The purpose of this application is to propose an automatic drainage device for an air compressor in view of the above problems existing in the prior art.

[0005] This application can be realized through the following technical solutions: An automatic drainage device for an air compressor includes an automatic drainage valve. The automatic drainage valve is installed on the air storage tank of the air compressor. The automatic drainage valve is used to allow water to leave the air storage tank. A water outlet pipe is installed at the water outlet of the automatic drainage valve. The water outlet pipe is used to send water into the interior of a filter box. There is an upward-opening filter basket in the filter box, and the filter basket is used to filter impurities in the water. A drain pipe is installed at the bottom of the filter box, and the drain pipe is used to drain the filtered water out of the filter box. The drain pipe is connected to a water storage tank.

[0006] In the above technical solution, the automatic drainage valve can drain the water in the air storage tank into the water outlet pipe. The water discharged from the air storage tank will contain solid impurities such as rust. The water in the water outlet pipe can enter the filter box and be filtered by the filter basket. The filtered water can be discharged out of the filter box through the drain pipe and stored in a water storage tank for later use.

[0007] Further, the filter box is provided with an upward opening, and the filter box is provided with a cover plate that can close its own opening. The drain pipe passes through the cover plate and extends into the filter basket.

[0008] In the above technical solution, the cover plate can be opened to clean the filter basket, which is relatively convenient.

[0009] Furthermore, a cooling pipe is installed on the water tank, and the cooling pipe is used to supply water to leave the water tank. The cooling pipe runs through a cooling box. An air conditioner is provided in the cooling box, and the air conditioner is used to cool the water in the cooling pipe. The end of the cooling pipe away from the water tank and the cooling box in the length direction is used to be wound around a designated device, and the water can cool the designated device through the cooling pipe.

[0010] In the above technical scheme, the designated equipment is equipment with a higher operating temperature. The water in the water tank can enter the cooling pipe, and then the water in the cooling pipe enters the cooling box. The air conditioner can send cold air to the cooling pipe and thus cool the water in the cooling pipe. One end of the cooling pipe away from the length direction of the water tank and the cooling box is wound around the designated equipment. The water cooled by the air conditioner can cool the designated equipment through the cooling pipe and thus reduce the operating temperature of the designated equipment.

[0011] Furthermore, a plurality of elastic clamps are provided in the cooling box, and the plurality of elastic clamps are used to guide the movement path of the cooling pipe so that the cooling pipe is arranged in a bent state in the cooling box.

[0012] In the above technical solution, the elastic clamping ring can be used to clamp the cooling pipe, and several elastic clamping rings can guide the movement path of the cooling pipe so that the cooling pipe is bent in the cooling box. This design can increase the movement path length of the water in the cooling box and have a better cooling effect on the water in the cooling pipe.

[0013] Furthermore, the elastic clamping ring is formed with a support, and the support is installed on the inner wall of the cooling box through a fixing assembly.

[0014] In the above technical solution, a support is provided and fixed to the inner wall of the cooling box through a fixing assembly. This design facilitates the installation of the elastic clamping ring.

[0015] Furthermore, the fixing assembly includes a slider slidably connected to the support, a spring forcing the slider to extend out of the support, and a limit block installed on the inner wall of the cooling box and capable of contacting the upper surface of the slider. An installation groove is provided on the inner wall of the cooling box, and the installation groove is used for the support to be embedded. The limit block can abut against the slider to limit the displacement of the slider in the depth direction of the installation groove.

[0016] In the above technical solution, the slider is pressed to retract it into the support, and then the support is embedded in the mounting groove. Then, the slider is released. When the slider is located below the limit block, it can be exposed from the support due to the elastic force of the spring. At this time, the upper surface of the slider can abut against the lower surface of the limit block. The mounting groove can limit the horizontal movement of the support, and the limit block can limit the vertical movement of the slider, thereby fixing the position of the support relative to the cooling box.

[0017] Further, an inclined surface is formed on the slider, and the inclined surface can contact the limiting block so that the slider can retract into the penetrating rod.

[0018] In the above technical solution, the inclined surface can contact the limiting block so that the slider can retract into the penetrating rod by itself, which is more convenient.

[0019] Further, the limiting block and the cooling box are connected by screws.

[0020] In the above technical solution, the limiting block and the cooling box are connected by screws. If the elastic snap ring breaks, this design facilitates the disassembly of the limiting block, and thus facilitates the disassembly of the elastic snap ring.

[0021] In summary, the present application has the following technical effects: The automatic drain valve can drain the water in the air storage tank into the outlet pipe. The water discharged from the air storage tank may contain solid impurities such as rust. The water in the outlet pipe can enter the filter box and be filtered by the filter basket. The filtered water can be discharged from the filter box through the drain pipe and stored in a water storage tank for later use. BRIEF DESCRIPTION OF THE DRAWINGS
