Description
Technical field
The present invention relates to filter technical field, specially a kind of quiet close filter of freeze drier.
Background technology
Freezing type drier uses physical principle, and the moisture in compressed air is refrigerated to below dew point, makes water from air
The dried-air drier of middle precipitation.Due to containing a variety of mechanical admixtures in air, therefore in the water separated out from air just
Correspondingly contain a variety of mechanical admixtures, if not carrying out filtration treatment to above-mentioned mechanical admixture, air flue will be caused
Block, the operation principle of freezing type drier is：The compressed air of moist high temperature flows into precooler（High temperature modification is special）Dissipate
Inflow heat exchanger carries out heat exchange with the cold air ejected from evaporator after heat, makes the temperature into the compressed air of evaporator
Degree reduces.
But the existing quiet close filter of freeze drier, it is impossible to the impurity different to granular size carries out layered filtration,
Easily block, and upper filter and lower filter have adhered to some impurity, impurities accumulation after filter is using a period of time
Filter permeability can be excessively influenceed, staff needs to change cleaning filter core, so as to add the workload of staff,
In-convenience in use.
The content of the invention
It is an object of the invention to provide a kind of quiet close filter of freeze drier, to solve to carry in above-mentioned background technology
The problem of going out.
To achieve the above object, the present invention provides following technical scheme：A kind of quiet close filter of freeze drier, including
Main body, the main body include housing and the air inlet pipe, blast pipe, return duct and the scum pipe that are arranged on housing, the air inlet pipe,
Blast pipe, return duct and scum pipe communicate with the cavity of the enclosure interior, are provided with filter core in the housing, in the housing
The cavity in portion is divided into purified gas body cavity and dirty air chamber, the blast pipe, return duct and the purification gas by filter core
Chamber communicates, and the air inlet pipe and scum pipe communicate with the dirty air chamber, and the return duct communicates with the blast pipe, described
It is provided with return valve on return duct, the outlet side of the blast pipe is provided with drain tap, the row of being provided with the scum pipe
Slag valve.
Preferably, the filter core includes upper filter and lower filter, and the filter opening diameter of the upper filter is less than the filter of lower filter
Bore dia.
Preferably, the housing is made up of the semimetal housing seal connection of two groups of mutual cooperations.
Preferably, the blast pipe is communicated by return duct with the purified gas body cavity.
Preferably, connected between the blast pipe and the return duct by tee pipe fitting.
Compared with prior art, the beneficial effects of the invention are as follows：The present invention by filter core by being arranged to upper filter and lower filter
Core double-decker, the filter opening diameter of upper filter are less than the filter opening diameter of lower filter, and the aperture of lower filter is larger to be used to filter particle
Larger impurity, the aperture of upper filter is used to filter the less impurity of particle compared with lower, so as to prevent blocking；Used in filter
Upper filter and lower filter have adhered to some impurity after a period of time, and impurities accumulation can excessively influence filter permeability, this
When, drain tap is closed, return valve, slag-discharging valve are opened, by the way that the air of purification is inversely passed through into filter core, by filter core
Impurity blowout, discharged by scum pipe, consequently facilitating cleaning, prevent from blocking, have it is simple in construction, easy to use, use effect
The advantages that fruit is good.

Embodiment
Below in conjunction with the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is carried out clear, complete
Site preparation describes, it is clear that described embodiment is only part of the embodiment of the present invention, rather than whole embodiments.It is based on
Embodiment in the present invention, those of ordinary skill in the art are obtained every other under the premise of creative work is not made
Embodiment, belong to the scope of protection of the invention.
Fig. 1-2 is referred to, the present invention provides a kind of technical scheme：A kind of quiet close filter of freeze drier, including master
Body 10, the main body 10 include housing 2 and the air inlet pipe 1, blast pipe 7, return duct 9 and the scum pipe 5 that are arranged on housing 2, institute
State air inlet pipe 1, blast pipe 7, return duct 9 and scum pipe 5 to communicate with the cavity inside the housing 2, be provided with the housing 2
Filter core 3, the cavity inside the housing 2 are divided into purified gas body cavity 12 and dirty air chamber 4, the blast pipe by filter core 3
7th, return duct 9 communicates with the purified gas body cavity 12, and the air inlet pipe 1 and scum pipe 5 communicate with the dirty air chamber 4, institute
State return duct 9 to communicate with the blast pipe 7, return valve 8 is provided with the return duct 9, the outlet side of the blast pipe 7 is set
Drain tap 11 is equipped with, slag-discharging valve 6 is provided with the scum pipe 5.
The filter core 3 includes upper filter 31 and lower filter 32, and the filter opening diameter of the upper filter 31 is less than lower filter 32
Filter opening diameter, the aperture of lower filter 32 is larger to be used to filter the larger impurity of particle, and the aperture of upper filter 31 is relatively lower to be used to filter
The less impurity of particle, so as to prevent blocking；The housing 2 is made up of the semimetal housing seal connection of two groups of mutual cooperations；
