Anti-oscillation drying tank with compact structure

Abstract

The invention relates to the field of air drying devices, and discloses an anti-oscillation drying tank with compact structure. The anti-oscillation drying tank comprises a heat exchange passage (36),wherein the heat exchange passage (36) is surrounded by the outside wall of a drying casing (33), the outside wall of a coalescent filter (35) and the inside wall of a tank body (30); the air flow isexhausted out of an air outlet (32) sequentially through an air inlet (31), the heat exchange passage (36), the coalescent filter (35) and a drying cavity (34); the drying casing (33) comprises a lower first casing body (37) and an upper second casing body (38), the second casing body (38) is positioned above the first casing body (37), the inner diameter of the second casing body (38) is smallerthan the inner diameter of the first casing body (37), and a connecting plate for connecting the first casing body (37) and the second casing body (38) is a transition plate (39); the coalescent filter (35) is positioned above the transition plate, and is sheathed at the exterior of the second casing body. The anti-oscillation drying tank is characterized in that the cost of a check valve is low,and the anti-oscillation drying tank is suitable for multiple types of installation space; the oscillation system is not produced, the service life is long, the cost is low, the size is small, and the like.

Description

technical field [0001] The invention relates to the field of vehicle compressed air drying and cleaning devices, in particular to a compact anti-vibration drying tank. Background technique [0002] The U.S. Patent Publication No. US20080289505A5 patent application document and the European Patent Grant Publication No. EP1495934B1 disclose a type of air dryer, which represents an existing air dryer for most of the global vehicle market. Technical air drying cylinder, the specific structure is as figure 1 shown. This kind of air drying cylinder has the following defects. [0003] First, since the air system is supplied by an air compressor. During compression, the compressed air is contaminated with oil droplets and hard carbon particles. Moisture in the air can also condense and form droplets. These water droplets can form emulsions with oil droplets. All of the aforementioned contamination is harmful to the components of the vehicle's air system, so it must be filtered...

AI Technical Summary

Problems solved by technology

Since gravity is used to collect the oil, it also limits the installation of the dryer cartridge to a near vertical

[0005] Third, the coalescing filter element 2 may be blocked by particles or by freezing during the filtration process

But this way has the following disadvantages, the location of the first check valve 16 has some disadvantages: the first check valve 16 is directly in contact with the incoming hot air, so it must be made of heat resistant material, which makes it more expensive

These dead space volumes reduce the amount of desiccant material 18 and increase the size of the drying cartridge
