Description
Technical field
Filter technical field is the utility model is related to, 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
The purpose of this utility model is to provide a kind of freeze drier quiet close filter, to solve above-mentioned background technology
The problem of middle proposition.
To achieve the above object, the utility model provides following technical scheme：A kind of quiet close filter of freeze drier,
Including main body, the main body includes housing and the air inlet pipe, blast pipe, return duct and the scum pipe that are arranged on housing, it is described enter
Tracheae, blast pipe, return duct and scum pipe are communicated with the cavity of the enclosure interior, and filter core is provided with the housing, described
The cavity of enclosure interior is divided into purified gas body cavity and dirty air chamber by filter core, the blast pipe, return duct with it is described net
Change air chamber to communicate, the air inlet pipe and scum pipe communicate with the dirty air chamber, the return duct and the blast pipe phase
It is logical, return valve is provided with the return duct, the outlet side of the blast pipe is provided with drain tap, set on the scum pipe
It is equipped with slag-discharging 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 utility model are：The utility model by filter core by being arranged to upper filter
Core and lower filter 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 for
The larger impurity of particle is filtered, the aperture of upper filter is used to filter the less impurity of particle compared with lower, so as to prevent blocking；Filtering
Device has adhered to some impurity using upper filter after a period of time and lower filter, and impurities accumulation can excessively influence filter and lead to
Permeability, now, drain tap to be closed, return valve, slag-discharging valve are opened, by the way that the air of purification is inversely passed through into filter core,
Impurity on filter core is blown out, discharged by scum pipe, consequently facilitating cleaning, prevents from blocking, have simple in construction, user
Just the advantages that, using effect is good.

Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the embodiment of the utility model is carried out
Clearly and completely describing, it is clear that described embodiment is only the utility model part of the embodiment, rather than whole
Embodiment.Based on the embodiment in the utility model, those of ordinary skill in the art are not under the premise of creative work is made
The every other embodiment obtained, belong to the scope of the utility model protection.
Fig. 1-2 is referred to, the utility model provides a kind of technical scheme：A kind of quiet close filter of freeze drier, bag
Main body 10 is included, the main body 10 includes housing 2 and the air inlet pipe 1, blast pipe 7, return duct 9 and the scum pipe that are arranged on housing 2
5, the air inlet pipe 1, blast pipe 7, return duct 9 and scum pipe 5 communicate with the cavity inside the housing 2, pacify in the housing 2
Equipped with filter core 3, the cavity inside the housing 2 is divided into purified gas body cavity 12 and dirty air chamber 4, the row by filter core 3
Tracheae 7, return duct 9 communicate with the purified gas body cavity 12, the air inlet pipe 1 and scum pipe 5 and the dirty phase of air chamber 4
Logical, the return duct 9 is communicated with the blast pipe 7, and return valve 8 is provided with the return duct 9, and the blast pipe 7 goes out
