Specific embodiment

The principles of the present invention and feature are described below in conjunction with attached drawing, example is served only for explaining that this is practical It is novel, it is not intended to limit the scope of the utility model.

Embodiment 1

As shown in Figure 1, including blowback pipeline 3, preposition drying device 1 and the air compressor machine 2 with compression air flow channel, it is preposition One end of drying device 1 is connected to the input terminal of air compressor machine 2, and the middle part of compression air flow channel is connected to blowback pipeline 3.Anti-blowpipe Valve 4 is installed on road 3.

Specifically, air compressor machine 2 is centrifugal air compressor, compression air flow channel is what air flowed in air compressor machine 2 Runner, that is, the air input passage for the impeller being equipped with receive the channel in the spiral case to be pressurizeed by centrifugal force and pass through spiral case It is existing skill afterwards from the output channel for being sent to next air suction passage for being equipped with impeller or sending out compressed air Art.

After air compressor machine 2 stops working, usual condensed water can gradually agglomerate, at this point, by blowback pipeline 3 and finished product compressed gas Valve 4 is opened in connection, and finished product compressed gas enters the middle part of the compression air flow channel in air compressor machine 2, and is purged to both ends, Condensed water aggregation corrosion is avoided, guarantees 2 normal use of air compressor machine.

Preposition drying device 1 includes the cabinet for offering porting, is filled with desiccant in cabinet.Pass through desiccant elder generation Air is subjected to moisture absorption, reduces the moisture in air compressor machine 2, reduces the condensation number of condensed water.Preferably, desiccant using silica gel, Molecular sieve etc..

Embodiment 2

As shown in Figure 1, 2, the present embodiment the difference from embodiment 1 is that, the cylinder of preposition drying device 1 including open at both ends Body 5, cylinder 5 is interior to be equipped with multiple annular partitions 6, and the external annulus of annular partition 6 is fixed on the inner wall of cylinder 5, two neighboring ring Annular is mounted between shape partition 6 blocks net cylinder A7, and the both ends for blocking net cylinder A7 are separately fixed at two adjacent annulars On partition 6, and block net cylinder A7 and annular partition 6 is coaxially arranged, the internal diameter for blocking net cylinder A7 is greater than the centre bore of annular partition 6 Internal diameter, circular bulkheads 8 are equipped between two neighboring annular partition 6, the periphery wall of circular bulkheads 8, which is fixed on, blocks net cylinder A7's On inner wall, the centre bore positioned at an annular partition 6 of 5 one end of cylinder is connected to through pipeline with the input terminal of air compressor machine.Adjacent two It is equipped between a circular bulkheads 8 and blocks net cylinder B11, the both ends for blocking net cylinder B11 are separately fixed at two adjacent circular bulkheads 8 On, each block the interior of an annular partition 6 of the outer wall of net cylinder B11 between corresponding two adjacent circular bulkheads 8 Ring wall is fixedly connected.Two annular partitions 6 positioned at 5 both ends of cylinder are equipped between circular bulkheads 8 adjacent thereto blocks net Cylinder C12, the both ends for blocking net cylinder C12 are separately fixed on corresponding annular partition 6 and corresponding circular bulkheads 8.

Specifically, blocking net cylinder A7, blocking net cylinder B11, block the mesh size of net cylinder C12 less than single in desiccant The size of grain, to prevent desiccant from leaking out out of annular compartment.Net cylinder A7 is blocked, net cylinder B11 is blocked, blocks net cylinder C12 and right Annular compartment is surrounded between the circular bulkheads 8 answered, annular partition 6, annular compartment is for placing desiccant.

5 open at both ends of cylinder, the hole among annular partition 6 that air passes through 5 one end of cylinder enters in cylinder 5, in circle Under the barrier action of partition 8, air along circular bulkheads 8 radial diffusion, by way of annular compartment, with the indoor desiccant of annular chamber Enter 5 inside of cylinder after coming into full contact with and block the cavity between 7 outside of net cylinder, and due to the barrier action of annular partition 6, it is empty Gas is obstructed to aggregation at the center of annular partition 6 into the hole of 6 centre of annular partition by next circular bulkheads 8 ... Last air is outer for compressor use from the hole output cylinder 5 among the annular partition 6 of 5 other end of cylinder.In this process In, air comes into full contact with desiccant, achievees the effect that pre-dehumidified.

The axis 9 arranged with 5 axis parallel of cylinder is equipped in cylinder 5, on multiple circular bulkheads 8 and multiple annular partitions 6 Circular through hole is offered, multiple circular through holes are coaxially arranged and the centerline axis parallel of center axis thereof and cylinder 5 is arranged, axis 9 sequentially pass through multiple circular through holes is slidably connected with circular through hole.One end that axis 9 stretches out outside cylinder 5 has hand-held part 10.

After air compressor machine 2 works a period of time, the desiccant in preposition drying device 1 absorbs the close saturation of moisture, this When axis 9 can be extracted out out of circular through hole, the indoor desiccant of annular chamber can be poured out out of cylinder 5 through circular through hole, carry out Replacement.

The above is only the preferred embodiments of the utility model, are not intended to limit the utility model, all in the utility model Spirit and principle within, any modification, equivalent replacement, improvement and so on should be included in the protection model of the utility model Within enclosing.
