Abstract
The utility model provides a filter that contains special exhaust structure, including filter shell, filter core and nut, be equipped with a gas vent at the top of shell, the bottom is equipped with inlet and liquid outlet, is equipped with a seal groove in the gas vent, leaves one section space in the below of seal groove, and the space is built -in to have a floater, is equipped with the flange of round closed angle at this space lower extreme, and the internal diameter that the flange round encloses will be less than the external diameter of floater to, the floater will adopt the material lighter than water to make. The filter core includes the interface, crew cut and filter media, the liquid outlet of interface and shell is linked together, crew cut surface distribution a plurality of gas pockets, surface weld has one deck filter paper on flat headed, the hydrophobic thin oil of this filter paper, and filterable precision will be higher than the precision of filter media, its purpose is, the inside air of filter core sees through the inside that filter paper was emited into the shell via the gas pocket on the crew cut, the outside of filter core, discharge via the gas vent of shell again, and this in -process, because the hydrophobic thin oil of filter paper, the inside filtrating of filter core can not overflow outsidely to the filter core. The utility model discloses a nut communicates with the inside of gas vent.
Description
Technical field
This utility model relates to a kind of filter, a kind of filter containing special exhaust structure.
Background technology
This utility model filters for lithium battery serosity, aqueous solution, aggressive solvent, photoresist etc..This type of filter is generally provided with inlet, liquid outlet and air vent on shell, and air vent is generally disposed at shell highest point, in order to while stock solution enters, replaced away from air vent by air.
Normal conditions, when gas will drain, then screw nut, if any accidentally, may result in stock solution and overflow from air vent and cause revealing, especially when stock solution be some there is corrosive solvent time, environment can be had certain harm.Therefore, change filter conventional exhaust mode, reduce aerofluxus leakage and become industry problem demanding prompt solution.
Summary of the invention
This utility model provides a kind of filter containing special exhaust structure, including filter housing, filter element and nut,
Wherein:
Cover top portion is provided with air vent, and bottom is provided with inlet and liquid outlet, is wherein provided with a seal groove in air vent, is built-in with a sealing ring, is provided with one section of space below seal groove, is built-in with a ball float；
Filter element includes interface, tack and filter material, and wherein interface is connected with liquid outlet, the some pores of tack surface distributed, and is welded with a metafiltration paper at tack upper surface.
Preferably, the lower end in space is provided with a circle wedge angle flange, and the internal diameter that this flange is surrounded is less than the external diameter of ball float.
Preferably, ball float uses the material that density is lighter than water to make.
Preferably, filter paper hydrophobic oleophobic, and the precision filtered is higher than filter material.
Preferably, nut connects with inside exhaust ports.
Can be seen that from such scheme, this utility model provides a kind of filter containing special exhaust structure, including filter housing, filter element and nut, an air vent it is provided with at the top of shell, bottom is provided with inlet and liquid outlet, a seal groove it is provided with in air vent, one section of space is left in the lower section of seal groove, space is built-in with a ball float, the flange of a circle wedge angle it is provided with in this lower end, space, the internal diameter that flange one circle is surrounded is less than the external diameter of ball float, and, ball float to use the material lighter than water to make, it provides the benefit that, when stock solution enters the top that shell rises to filter, this ball float can be pushed at sealing ring, air vent is made to close.Filter element of the present utility model includes interface, tack and filter material, interface is connected with the liquid outlet of shell, tack surface distributed some pores, upper surface at tack is welded with a metafiltration paper, this filter paper hydrophobic oleophobic, and the precision filtered is higher than the precision of filter material, it provides the benefit that, filter element inner air is discharged into the outside of the inside of shell, filter element via the pore on tack through filter paper, discharge via the air vent of shell again, and during this, due to filter paper hydrophobic oleophobic, filter element internal filtrate will not be overflow to filter element.Nut of the present utility model connects with the inside of air vent.
Accompanying drawing illustrates:
Fig. 1 is a specific embodiment of the present utility model；
Fig. 2 is the concrete schematic diagram of this utility model air vent；
Fig. 3 is the part sectioned view of this utility model tack upper surface；
Fig. 4, Fig. 5, Fig. 6 are this utility model aerofluxus schematic diagram.
Detailed description of the invention:
This utility model provides a kind of filter containing special exhaust structure, to reach automatic aerofluxus, it is to avoid the purpose that stock solution is revealed.
Illustrate below in conjunction with accompanying drawing of the present utility model, the technical scheme in this utility model is carried out clear, complete description, it is clear that described embodiment is only the embodiment of this utility model part rather than whole embodiments.Based on the embodiment in this utility model, the every other embodiment that those of ordinary skill in the art are obtained under not making creative work premise, broadly fall into protection domain of the present utility model.
Fig. 1 is a specific embodiment of the present utility model, including filter housing 1, filter element 2 and nut 3, is provided with an air vent 13 at the top of shell, and bottom is provided with inlet 11 and liquid outlet 12.As shown in Figure 2, a seal groove 14 it is provided with in air vent 13, one section of space 15 is left in the lower section of seal groove 14, space is built-in with a ball float 4, the flange 16 of a circle wedge angle it is provided with in this lower end, space 15, the internal diameter that flange 16 1 circle is surrounded is less than the external diameter of ball float 4, and, ball float 4 to use the material lighter than water to make, filter element 2 of the present utility model includes interface 21, tack 22 and filter material 23, interface 21 is connected with the liquid outlet 12 of shell 1, tack 22 surface distributed some pores 25, upper surface at tack 22 is welded with a metafiltration paper 24, this filter paper 24 hydrophobic oleophobic, and the precision filtered is higher than the precision of filter material 23.Nut 3 is installed on air vent 13, and nut 3 is provided with a through hole, and this through hole connects with air vent 13.
As shown in Figure 4, when stock solution enters shell 1 inside via inlet 11, a part is filtered by filter material 23 in entering filter element becomes filtrate, a part rises along with the entrance of stock solution, air outside shell 1 inside, filter element 2 is displaced air vent simultaneously, meanwhile, the height of the filtrate within stock solution height and filter element 2 can form the resistance difference of a filter material 23, and it is internal that this difference makes portion of air stay filter element 2.
As it is shown in figure 5, along with stock solution rises, the filtrate filtered within entrance filter element via filter material 23 also raises, the air assembling filter element inner top is drained into stock solution side by filter paper 24 simultaneously.
As shown in Figure 6, until the air within filter element 2 is replaced by filtrate completely and drains into stock solution side, discharge via air vent 13 again, now filter interior is entirely without air, meanwhile, owing to the density of ball float 4 is lighter than liquid, therefore ball float 4 can be pushed at sealing ring 3 by stock solution, ball float 4 seals with sealing ring 3, makes air vent 13 close, and therefore stock solution will not leak.
