Description

Technical Field

[0001] The utility model relates to the technical field of precision compressed air filter elements, in particular to a precision compressed air filter element. Background Art

[0002] The main function of precision compressed air filter is to filter out impurities and tiny particles in compressed air, such as water droplets, grease, dust, bacteria and viruses. Precision compressed air filter elements are made of a variety of different materials, the most common of which are polyamide membrane, glass fiber, cellulose, ceramic and stainless steel;

[0003] The air humidity in some places is high, and conventional precision compressed air filter elements cannot effectively remove water vapor in the air before filtration, causing impurities and water vapor in the air to enter the precision compressed air filter element. After the precision compressed air filter element filters them, the water vapor and impurities will remain on the surface of the precision compressed air filter element, which is easy to agglomerate and cause blockage, reducing the service life of the precision compressed air filter element and increasing the cleaning cycle. At the same time, the agglomerates adhere to the surface of the precision compressed air filter element and are not easy to clean. Utility Model Content

[0004] The utility model aims to solve the shortcomings in the prior art and proposes a precise compressed air filter element.

[0005] In order to achieve the above-mentioned purpose, the utility model adopts the following technical scheme: a precision compressed air filter element, including an air inlet pipe, the bottom of the air inlet pipe is fixedly connected to a shell, a refrigeration component is installed inside the shell, the bottom of the refrigeration component is symmetrically fixedly connected to two special-shaped copper plates, one side of the outer surface of the two special-shaped copper plates is matched with a multi-bump copper plate, the outer surfaces of the two multi-bump copper plates are commonly fixedly connected to an air bundle pipe, the inner surface of the air bundle pipe is fixedly connected to a plurality of oblique blocks, the outer surface of the air bundle pipe is provided with a plurality of air outlets matching the oblique blocks, the outer surface of the air bundle pipe is sealingly and rotatably connected to an air distribution pipe, the outer surface of the air bundle pipe is fixedly sleeved with two end covers, a metal filter is commonly fixedly connected between the two end covers, and the outer surface of the metal filter is fixedly sleeved with a cellulose layer fixedly connected to the two end covers.

[0006] Furthermore, the refrigeration component includes a semiconductor refrigeration plate, and the semiconductor refrigeration plate is fixedly embedded in the outer wall of the shell, the cooling end of the semiconductor refrigeration plate is attached to a heat sink fixedly connected to the shell, the cooling end of the semiconductor refrigeration plate is attached to a heat conductive block, and the heat conductive block is fixedly connected to the special-shaped copper plate and the multi-bump copper plate, so that the special-shaped copper plate and the multi-bump copper plate can be cooled, thereby facilitating the condensation of the incoming air.

[0007] Furthermore, the air distribution pipe includes a pipe body, and the pipe body is sealed and rotatably connected to the outer surface of the air bundle pipe. A plurality of inclined pipes are fixedly passed through the outer surface of the pipe body. When the air is discharged through the inclined pipes, the pipe body can be driven to rotate, which is conducive to the uniform distribution of compressed air in the filter element.

[0008] Furthermore, the plurality of air outlets are all located inside the tube body, ensuring that the compressed air entering the air bundle pipe can only enter the tube body.

[0009] Furthermore, a support net fixedly connected to the two end covers is fixedly sleeved on the outer surface of the cellulose layer, and the arrangement of the support net can ensure the strength of the filter element.

[0010] Furthermore, two through holes are symmetrically opened on the top of the heat conductive block and penetrate to the bottom, and the through holes match the gap between the special-shaped copper plate and the adjacent multi-bump copper plate, which is conducive to the compressed air entering the air bundle pipe.

[0011] Furthermore, a drainage pipe is fixedly connected to the bottom of the air bundle pipe, so that water in the air bundle pipe can be drained regularly.

[0012] Beneficial effects of the utility model:

[0013] When the utility model is in use, the precision compressed air filter element can condense the air in the air intake filter element through the arranged refrigeration component, special-shaped copper plate, multi-protrusion copper plate, oblique baffle and air bundle pipe, so that the water vapor in the air condenses into small water droplets, thereby preventing the water vapor from entering the filter element and combining with dust to form blocks, causing the filter element to be blocked and difficult to clean; and then through the arranged air distribution pipe, the air is used to rotate the air distribution pipe to evenly distribute the air in the filter element, thereby avoiding stress concentration and protecting the filter element.

[0020] The refrigeration component includes a semiconductor refrigeration plate 12, and the semiconductor refrigeration plate 12 is fixedly embedded in the outer wall of the shell 3, the cooling end of the semiconductor refrigeration plate 12 is attached to the heat sink 2 fixedly connected to the shell 3, the cooling end of the semiconductor refrigeration plate 12 is attached to the heat conducting block 8, and the heat conducting block 8 is fixedly connected to the special-shaped copper plate 10 and the multi-bump copper plate 14.

[0021] After the semiconductor refrigeration sheet 12 is started, the heat generated is dissipated into the air through the radiator 2, and the cold energy generated is transmitted to the special-shaped copper plate 10 and the multi-bump copper plate 14 through the heat-conducting block 8, thereby condensing the incoming compressed air.

[0022] Two through holes extending from the top to the bottom are symmetrically provided on the top of the heat conducting block 8 , and the through holes match the gap between the special-shaped copper plate 10 and the adjacent multi-bump copper plate 14 , which is conducive to the compressed air entering the air bundle pipe 11 .
