Abstract
The utility model relates to an air drier, which comprises two drying towers, wherein one ends of the two drying towers are respectively connected with an inlet shuttle valve and a solenoid valve; the other ends of the two drying towers are respectively connected with an outlet shuttle valve and a regenerated gas duct; and a flow regulating valve is arranged on the regenerated gas duct. The air drier has the advantages of fewer valves, simple structure, small size, light weight, high reliability, and almost no maintenance during operation, and can be used for equipment needing dry air.
Description
Technical field
The utility model relates to air dryer, relates in particular to the pressure change adsorption type air dryer.
Background technology
The pressure change adsorption type air dryer is to utilize the adsorbent (for example molecular sieve) that is positioned in the drying tower to have the characteristic of different adsorption capacities, adsorption rate and absorption affinity to be made under different pressure to airborne steam: utilize a molecular sieve in the drying tower to remove the steam that compresses in the humid air, obtain dry air; The dry air decompression desorption that utilizes a part to obtain again suctions the molecular sieve in another drying tower of moisture.Therefore, adopt a plurality of drying towers, the pressure in each drying tower is made up in change circularly, just can reach the purpose of continuous drying air.
Existing air dryer comprises that 2 drying towers, 2 check-valves, 4 magnetic valves, 1 regeneration gas control valve and electric cabinet etc. connect and compose.7 valves are wherein arranged, mechanism's complexity, the cost height, reliability is lower.
The utility model content
The utility model has carried out research and has improved at the problems referred to above of existing air dryer, and a kind of pressure change adsorption type air dryer simple in structure is provided, and its manufacturing cost is lower, and reliability is higher.
In order to solve the problems of the technologies described above, the utility model adopts following technical scheme:
The utility model comprises two drying towers, one end of two drying towers connects import shuttle valve and magnetic valve respectively, the inlet end of described import shuttle valve is the input of compression humid air, the output of import shuttle valve is connected with the input of two drying towers and magnetic valve respectively, and the output of described magnetic valve is the port of export of regeneration gas; Two drying towers the other end connect outlet shuttle valve and regeneration gas conduit respectively, on the regeneration gas conduit flow control valve is installed, the output of described outlet shuttle valve is the output of dry air.The output of described magnetic valve is equipped with silencer.
Technique effect of the present utility model:
Valve was few when the utility model used, and was reduced to five by seven valves that have air dryer now, designs simplification, and volume is little, and is in light weight, carries out programme-control by controller, full automatic working, the reliability height, almost non-maintaining.
Description of drawings
Fig. 1 is a structural representation of the present utility model
The specific embodiment
Below in conjunction with accompanying drawing the specific embodiment of the present utility model is further described.
The utility model comprises two drying towers 4,10, one end of two drying towers connects import shuttle valve 9 and magnetic valve 6,8 respectively, the inlet end 5 of described import shuttle valve 9 is the input of compression humid air, the output of import shuttle valve 9 is connected with two drying towers 4,10 respectively and is connected with the gas input of magnetic valve 6,8, and the output of described magnetic valve 6,8 is the port of export of regeneration gas; The other end of two drying towers 4,10 connects outlet shuttle valve 2 and regeneration gas conduit 11 respectively, and flow control valve 1 is installed on the regeneration gas conduit 11, and the output 3 of described outlet shuttle valve 2 is the output of dry air.The gas output end of described magnetic valve 6,8 is equipped with silencer 7, effectively reduces exhaust noise, adopts commercially available silencer.
During the utility model work, when humid air enters right tower 4 from import shuttle valve 9, steam quilt drier molecular sieve adsorption wherein, dry air is from the output output of outlet shuttle valve 2, meanwhile the small part dry air is introduced left tower 10 by regeneration gas conduit 11 and flow control valve 1, this dry air expands, and the moisture content in the drier in the left tower 10 is blown out.Close 2 magnetic valves then, left tower pressurising behind inlet pressure, is opened right tower magnetic valve, make 2 shuttle valves 2 and 9 commutations, humid air enters left tower 10 from import shuttle valve 9, left tower 10 suctions this moment, right tower 4 regeneration, beginning periodic duty.This cyclic process is carried out timing controlled by the single board computer in the controller (not drawing among the figure), and repetitive cycling provides the purification of compressed air of constant voltage continuously.Described controller adopts existing electronic control technology.
Claims (2)
1. air dryer, comprise two drying towers, one end of two drying towers connects import shuttle valve and magnetic valve respectively, the inlet end of described import shuttle valve is the input of compression humid air, the output of import shuttle valve is connected with the input of two drying towers and magnetic valve respectively, and the output of described magnetic valve is the port of export of regeneration gas; Two drying towers the other end connect outlet shuttle valve and regeneration gas conduit respectively, on the regeneration gas conduit flow control valve is installed, the output of described outlet shuttle valve is the output of dry air.
