Detailed description of the invention
Fig. 1 is a kind of structure chart for the filter core of resistance to acid/base provided by the utility model.
Fig. 2 is the structure chart that filter cloth is free of in Fig. 1.
Fig. 3 is the A-A direction view of Fig. 2.
Specific embodiment
As shown in Figure 1 to Figure 3, the filter core of resistance to acid/base provided by the utility model, including mounting disc 1, screen pipe, filter cloth 5.
Wherein, mounting disc 1 is hollow cylinder structure, and screen pipe is hollow tubular structure open at one end, filters one end of tube opening
It is fixedly connected, and is connected to by mounting disc 1 with external filtrate conduit, purge gas pipeline, while as filtrate with mounting disc 1
Outlet and purge gas import, it is preferable that purge gas is compressed gas, such as compressed air, to improve blowback efficiency.Filter
Cloth 5 is fixed on the periphery of screen pipe.
Screen pipe one end is connected to mounting disc, and other end sealing, the outer peripheral surface of screen pipe is equipped with multiple filtrates at other
In embodiment, the other end can also be equipped with multiple filtrate channels 23, and the effect of filtrate channel 23 is the filter for making to obtain after filtering
Liquid enters inside screen pipe, or makes to pass through inside purge gas inherent filtration pipe, to purge the filter cake being attached on filter cloth 5.
In other embodiments, the outer peripheral surface of screen pipe is equipped with multiple lug bosses, with three lug bosses in the present embodiment
For be illustrated, as shown in Figure 1 to Figure 3, three lug bosses are denoted as lug boss 2, lug boss 3 and lug boss 4, lug boss respectively
2, lug boss 3 and lug boss 4 are connected with each other, to expand the filter area of screen pipe.For the convenience installed, used, this implementation
In example, the cross section of lug boss is arc, and in other embodiments, the cross section of lug boss also can be made triangle, four sides
Any one or a few combination in shape, polygon.
Multiple filtrate channels 23 are additionally provided on 4 side of lug boss 2, lug boss 3 and lug boss, filtrate channel 23 is preferably logical
Hole, or the other shapes such as triangle, pentagon.In other embodiments, the bottom of screen pipe can also be equipped with filtrate
Channel 23.
In the present embodiment, the material of screen pipe is polypropylene (PP), polytetrafluoroethylene (PTFE), Kynoar (PVDF)
In any one, to improve acidproof, the alkaline resistance properties of screen pipe.In other embodiments, the material of screen pipe may be
Stainless steel can also be equipped with coating in the inside and or outside of stainless steel, such as coating 22, coating 32, coating 22, coating 32
Material is polypropylene (PP), polytetrafluoroethylene (PTFE), any one in Kynoar (PVDF).
Filter cloth 5 is fixed on the outer surface of screen pipe, and filter cloth 5 is made of porous material, such as textile fabric, filter cloth 5
Filter opening aperture is 0.01-100 μm, preferably 0.1-50 μm, such as 1 μm, 5 μm, 10 μm, 30 μm.
The side of mounting disc 1 is equipped with multiple mounting holes, and bolt passes through mounting hole, is fixedly connected with mounting disc and filtrate pipe
Road forms filtrate channel.
In other embodiments, the filter core of resistance to acid/base further includes blowback air entrance, and blowback air entrance passes through mounting disc and filtering
Pipe is connected to, the filter cake of screen pipe lateral surface described in blowback.
When using the filter core of resistance to acid/base filter core provided by the utility model, by external impetus equipment by the acid containing glass powder
The material inlet of liquid from the filter being used cooperatively with the filter core of the resistance to acid/base filter core enters filter interior, and contacts with filter cloth,
Filter cloth retains glass powder, and filtrate passes through filter cloth and enters inside screen pipe from filtrate channel, and the opening of inherent filtration pipe passes through
Mounting disc enters external filtrate conduit, and filtrate is recycled.After filtering a period of time, glass powder forms one layer of filter in filter cloth surface
Cake stops feeding into filter.
Purge gas valve is opened, high pressure gas self installation disk enters inside screen pipe, and passes through on screen pipe outer peripheral surface
Filtrate channel, filter cloth by high pressure gas squeeze after expand around, the moisture and part acid solution on filter cake are in high pressure gas
Drive under evaporate, and from be located at screen pipe lower part filtered solid outlet leave filter.And high pressure gas is in the mistake for passing through filter cloth
Cheng Zhong can take the glass powder in the filter opening of filter cloth out of, play the role of cleaning filter cloth.
With continuing to increase for the high pressure gas scale of construction, filter cake surface starts to generate crack, and gradually cracks, to be detached from filter cloth
Surface leaves filter from the filtered solid outlet for being located at screen pipe lower part, after filter cake leaves filter, completes a duty cycle.
External impetus equipment is reopened, acid solution of the filter filtering containing glass powder can be reused, without using every time
Mutual disassembly's filter cloth or hand washing filter cloth afterwards.
It can will be carried out by the filter cloth that blocks efficiently and quickly regeneration using the easy gas-liquid backblowing that quickly recoils,
Making filter cloth, the service life is longer, reduces operating cost.
Specific embodiment of the utility model is described in detail above, but it is only used as example, the utility model
It is not restricted to particular embodiments described above.To those skilled in the art, it is any to the utility model carry out
Equivalent modifications and substitution are also all among the scope of the utility model.Therefore, in the spirit and scope for not departing from the utility model
Equal transformation made by lower and modification, should all cover in the scope of the utility model.
