a compressed air filter

Abstract

The invention discloses a compressed air filter, which comprises a casing, a filter core connected to the inside of the casing, and a first valve connected to the bottom of the casing. The compressed air filter can realize control and compressed air filtration through a detection connection device provided. When the device detects that the water level inside the filter reaches a certain position, the water containing dregs will be discharged from the filter. While discharging, the device can scrape off the impurities attached to the inner wall of the filter. And drain the inside of the filter, close the connection after the water is drained, when the accumulated water in the device reaches a certain height, depressurize the water storage, and then pour out the water in the water storage to avoid When the water in the compressed air filter is discharged, it is necessary to stop the compressed air filter to reduce the working efficiency of the compressed air filter, and at the same time, it can improve the cleanliness of the compressed air filter for better use.

Description

technical field [0001] The invention relates to the technical field of compressed air, in particular to a compressed air filter. Background technique [0002] When the compressed air filter is in use, the compressed air carrying harmful substances such as dust, oil, rust and water can enter the first-stage filter device of the compressed air filter. When the compressed air passes through the first-stage cylindrical mesh filter element Coalescing effect occurs, larger particles will be adsorbed on the filter material, and the water will condense into larger water droplets. When entering the separation chamber, the compressed air speed will slow down, making the particles gather again, and the water mist will condense again in a On the honeycomb water trap, the water carrying impurity particles finally flows along the bottom to the drainage device, and is discharged through the drain valve at the bottom.

AI Technical Summary

Problems solved by technology

[0003] The compressed air filters currently on the market store water at the bottom when they are in use. When the water at the bottom is stored to a certain amount, the compressed air filter will stop working. By opening the exhaust port on the compressed air filter The hole reduces the internal pressure of the compressed air filter. When the internal pressure is reduced to the same as the external pressure, the drain valve at the bottom is opened to discharge the water from the bottom of the compressed air filter. This drainage method must make the filter during work The water can only be discharged after the filter stops working, which reduces the working efficiency of the compressed air filter, and the traditional drainage method only uses the gravity of the filtered water to make enough for the discharge valve to flow out, but the filtered water contains a lot of dross particles, so the inside of the filter During storage, the dross particles in the water are likely to stick to the inner wall of the filter, and a large number of impurity particles may adhere to the bottom of the filter during long-term use, and the position where the water is stored at the bottom of the filter and the filtered air inside The trajectory of the movement is interlinked, and a large number of impurity particles are likely to pollute the filtered air
