The operation principle of this timing return air drier:
Enter the first chamber A from air compressor machine compressed air out through the air inlet 1 of time return air drier, at this moment, because temperature declines, can produce condensed water, condensation flow is in the second chamber K.Air pressure drying cylinder 12 simultaneously, impurity, moisture content are taken off and are attached on the molecular sieve of drying 12.
Dried air is through the 3rd chamber B, and a part of gas directly outputs to gas equipment by delivery outlet 21 after check valve 8; Another part gas arrives the 4th cavity C through throttle orifice 10, first passage 11 and second channel 12, and gas pressure is on first piston 13, and first piston 13 moves right, and the nozzle valve 14 that makes to regenerate is closed; And another small part of gas arrives the 5th chamber D through timer nozzle 15.
In the process of air inlet, a part of gas of delivery outlet 21 arrives the 6th chamber E through hole 16, and acts on the second piston 17.In the time that the air pressure of delivery outlet 21 reaches the opening pressure of this timing return air drier, air pressure overcomes the power of the first spring 18, open valve 19, air pressure enters in the 6th chamber E of exhaust pition 20 tops, and promotes exhaust pition 20 and open drain tap 22 and enter in the second chamber K.Gas in the second chamber K and condensed water before, through built-in silencer 7, are discharged from exhaust outlet 3, and stress-relief process completes.
This timing return air drier is in the moment of exhaust release, because the air pressure of the 4th cavity C declines, cause the pressure in the 5th chamber D to be greater than the pressure in the 4th cavity C, now the first piston 13 between above-mentioned two chambers is moved to the left, regeneration nozzle valve 14 is opened, regeneration cycle starts, the portion gas in the 4th cavity C starts to enter in drying 12 by second channel 12, first passage 11 and throttle orifice 10, recoil molecular sieve, before making, on molecular sieve, residual impurity and moisture departs from, and realizes the regeneration of molecular sieve.Meanwhile, portion gas in the 5th chamber D is slowly discharged through timer nozzle 15, also enters the molecular sieve that recoils in drying 12.In the time that the pressure in the 4th cavity C and the 5th chamber D reaches balance, first piston 13 moves right, and promotes regeneration nozzle valve 14 and closes, and regeneration cycle completes.In this regenerative process, the pressure by the 4th cavity C and the 5th chamber D changes and causes the displacement of first piston 13, thereby has realized timing and quantitative air regenesis, and abundant regenerated molecular sieve has extended service life of drying.Can regulate recoil tolerance by adjustment screw 9.
Load onto a heater, can prevent that drain tap 22 is frozen in, thereby can avoid job failure to occur.
This timing return air drier has guaranteed that regeneration air amount keeps constant in air evolutionary process, and fully regenerated molecular sieve has extended service life of drying, and in regeneration cycle process, having guaranteed that compressed air pressure declines can breakdown pressure repercussion effect.Moreover, cancel regeneration air accumulator, thereby less auxiliary stand, unnecessary tracheae and adapter piece, make arrangement more convenient flexibly, integral vehicle cost and part deadweight are reduced, versatility, reliability and life-span are all greatly improved, and have realized the complete, succinct, dry and safe and effective of this dryer system.
The above, it is only preferred embodiment of the present utility model, be not the restriction of the utility model being made to other form, any those skilled in the art may utilize the technology contents of above-mentioned announcement to be changed or be modified as the equivalent embodiment of equivalent variations.But every technical solutions of the utility model content that do not depart from, any simple modification, equivalent variations and the remodeling above embodiment done according to technical spirit of the present utility model, still belong to the protection domain of technical solutions of the utility model.
