Abstract
The invention provides an arrangement method of a gas source of pneumatic valves of a drying machine. The drying machine comprises a front filter, a drying tower, an upper pneumatic valve and a lower pneumatic valve arranged on the upper end and the lower end of the drying tower respectively, a back filter, a drying machine pneumatic valve control loop and pipelines. Gas enters into the front filter via an air inlet arranged on the front side of the front filter, enters into the drying tower along the pipelines via the lower pneumatic valve, discharges via the upper pneumatic valve after drying, enters into the back filter via the pipelines, and finally discharges via an air outlet. The gas source is arranged at the back part of the back filter, part of the gas enters into the upper pneumatic valve and the lower pneumatic valve via the drying machine pneumatic valve control loop so as to form a power source. According to the arrangement method, gas impurity that enters into the drying machine pneumatic valve control loop is less, so that it is benefit for working stability of the drying machine.
Description
Technical field
The present invention relates to drying machine technical field, relate in particular to drying machine pneumatic operated valve source of the gas method to set up.
Background technology
As shown in Figure 1, at present conventional heatless regeneration absorption drier comprise fore filter 11', drying tower 23', at the upper pneumatic operated valve 22' at the upper and lower two ends of drying tower 23' and lower pneumatic operated valve 21', at post-filter 34' and magnetic valve 31', directed toward filter 32' between drying tower 23' and post-filter 34' and the pressure-reducing valve 33' at drying tower 23' rear.A side of fore filter 11' is provided with air inlet 1', and a side of post-filter 34' is provided with exhaust outlet 3'.Gas enters fore filter 11' via air inlet 1', then along pipeline 4', via lower pneumatic operated valve 21', enters drying tower 23', after gas is dried, by upper pneumatic operated valve 22', is discharged, and enters post-filter 34', and finally by exhaust outlet 3', discharged via pipeline 4'.Wherein there is Partial shrinkage gas to enter upper and lower pneumatic operated valve 22', 21' through pressure-reducing valve 33', directed toward filter 32', magnetic valve 31', as the power source of drying machine pneumatic operated valve control loop 5', other residual compression gases are discharged for upstream device by exhaust outlet 3' after pipeline 4' enters post-filter 34'.The source of the gas 2' operated by rotary motion of pneumatic operated valve is on the pipeline 4' between drying tower 23' and post-filter 34' at present, after compressed air drying captain's phase is dry, in drying tower 23', have the carbonization of partial oxidation alumina particles cracked, work long hours compressed air also together with equipment inner wall friction generating portion bushel iron bits, and this part aluminium oxide and bushel iron bits can be discharged drying tower 23' with dried compressed air simultaneously.
Owing to taking from the gas of this source of the gas, be mixed with aluminium oxide and iron filings particle, may cause drying machine pneumatic operated valve loop supply gas pressure compared with little and magnetic valve cisco unity malfunction, at this moment pneumatic operated valve can not cut out completely or open, strengthened drying machine unit compressed air air consumption, also increased compressed-air actuated waste, this will reduce the service life of drying machine.
In order to address the above problem, necessary above-mentioned drying machine pneumatic operated valve source of the gas method to set up is improved.
Summary of the invention
For the deficiencies in the prior art, the object of this invention is to provide a kind of improved drying machine pneumatic operated valve source of the gas improvement method.
Object of the present invention is by providing following technical scheme to realize: a kind of drying machine pneumatic operated valve source of the gas method to set up, described drying machine comprises fore filter, drying tower, be positioned at upper pneumatic operated valve and the lower pneumatic operated valve at the upper and lower two ends of drying tower, post-filter, drying machine pneumatic operated valve control loop and pipeline, gas enters fore filter via the air inlet arranging before fore filter, then along pipeline, via lower pneumatic operated valve, enter drying tower, after being dried, gas discharged by upper pneumatic operated valve, via pipeline, enter post-filter, and finally by exhaust outlet, discharged, after source of the gas is arranged at post-filter, thereby allow portion gas enter upper pneumatic operated valve and lower pneumatic operated valve formation power source via drying machine pneumatic operated valve control loop.
Compared with prior art, the invention has the beneficial effects as follows: source of the gas is arranged at and can allows to enter the gaseous impurity of drying machine pneumatic operated valve control loop less after post-filter, thereby is conducive to the stability of drying machine work.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, the invention will be further described:
Fig. 1 is current conventional drying machine source of the gas method to set up.
Fig. 2 is drying machine source of the gas method to set up of the present invention.
The specific embodiment
Referring to accompanying drawing, by preferred embodiment, implementation procedure of the present invention and essential content place are described.
Shown in ginseng Fig. 2, heatless regeneration absorption drier of the present invention comprises fore filter 11, drying tower 23, at the upper pneumatic operated valve 22 at drying tower two ends Shang Xia 23 and lower pneumatic operated valve 21, at post-filter 34 and the magnetic valve 31 between drying tower 23 and post-filter 34, directed toward filter 32 and the pressure-reducing valve 33 at drying tower 23 rears.Drying machine pneumatic operated valve control loop 5 of the present invention comprises magnetic valve 31, directed toward filter 32, pressure-reducing valve 33 and corresponding pipeline.
One side of fore filter 11 is provided with air inlet 1, and a side of post-filter 34 is provided with exhaust outlet 3.Gas enters fore filter 11 via air inlet 1, then along pipeline 4, via lower pneumatic operated valve 21, enters drying tower 23, after gas is dried, by upper pneumatic operated valve 22, is discharged, and enters post-filter 34, and finally by exhaust outlet 3, discharged via pipeline 4.Before the present invention is arranged at exhaust outlet 3 by source of the gas 2, Partial shrinkage gas enters upper and lower pneumatic operated valve 22,21 via pressure-reducing valve 33, directed toward filter 32, magnetic valve 31 like this, as the power source of drying machine pneumatic operated valve control loop 5.Other residual compression gases are discharged for upstream device via exhaust outlet 3.
Due to after source of the gas of the present invention is arranged at post-filter 34, Compressed Gas is through after the filtration of post-filter 34, the aluminium oxide wherein containing and iron filings particle all can be filtered mostly, this has greatly reduced entering of other particles in source of the gas introducing process, reduce the fault of the part of appliance causing thus, reduce the maintenance cost of equipment, improved the stability of equipment operation and the operating efficiency of equipment operation.In a preferred embodiment, the filtering accuracy of post-filter 34 is 0.01um.
Although be example object, the preferred embodiment of the present invention is disclosed, but those of ordinary skill in the art will recognize, in the situation that not departing from by the disclosed scope and spirit of the present invention of appending claims, various improvement, increase and replacement are possible.
