Novel efficient automobile air dryer

Abstract

The invention provides a novel efficient automobile air dryer which comprises a shell with the upper end closed, a bottom cover and a filter element. The bottom cover is provided with an air inlet anda threaded bayonet connected with an external air conveying pipeline. An inner container is arranged in the shell, and an inner container cover and a connecting disc are arranged on the inner container; a downward extending part in the middle of the bottom of the connecting disc is sleeved outside the threaded bayonet of the bottom cover; a drying agent storage cavity is formed by an inner cavityof the inner container; a spring is clamped between the inner container cover and the shell; a channel communicated with the inner container is formed in the inner container cover; an air channel isformed by a cavity between the inner container and the shell; the filter element is arranged on the upper portion of the inner container and communicated with the inner cavity of the inner container;a two-way bypass valve is further arranged on the channel of the inner container cover; a fixed rod is arranged in the center of the drying agent storage cavity in the vertical direction; a spiral piece is fixedly arranged on the fixed rod in a penetrating mode; and the outer contour of the spiral piece adapts to the inner wall of the inner container. Oil stains in compressed air can be filtered out, water is thoroughly removed, the automobile braking performance is ensured, and safety is improved.

Description

technical field [0001] The invention relates to the technical field of air dryers, in particular to a novel high-efficiency automobile air dryer. Background technique [0002] The car air dryer is an indispensable part of the car, especially for some heavy-duty cars. Its function is to dry the compressed air from the car pump, so that the moisture contained in the gas will not enter the brake system of the car through the gas. , so as to keep the car braking system sensitive and effective. [0003] Due to the serious phenomenon of oil leakage from domestic air pumps, the air coming out of the air pumps contains not only moisture, but also oil and solid impurities. The desiccant in ordinary car air dryers can only absorb moisture in the compressed air, but cannot The oil mist in the compressed air is pre-filtered. At the same time, the drying material in the air desiccant will lose the function of drying water after contacting with oil stains, which will quickly cause the d...

Problems solved by technology

[0006] The technical solution of "A Oil Filter Dryer for Air Dryer" with the patent application number 201820380584.3 is being implemented. Since the three-dimensional installation space of the dryer reserved in the vehicle design has been fixed, that is, the air dryer is limited by the installation space, and the height It cannot be designed too high. The height of the air dryer directly affects the height of the drying cylinder, which makes the path of compressed air through the molecular sieve shorter, because the air in the straight up and down air channel has a relatively short contact time with the molecular sieve, resulting in moisture in the air. If it is not fully absorbed, it will enter the pipeline system behind, which will affect the sensitivity and effectiveness of the automobile braking system; at the same time, due to the increase in resistance after a large amount of oil is absorbed in the air dryer, the air supply pressure of the braking system will be insufficient, which will affect the braking system. Dynamic performance, a potential safety hazard
