Description
Technical field
The present invention relates to a kind of filter, particularly relate to a kind of bottom cleaning device of filter.
Background technology
Present stage filter be industrial production manufacture in a requisite important step, along with the continuation of filter process, solid phase impurity in liquid is trapped in filter element surface, Pressure Drop in filter core is caused to increase, filtration resistance increases, filter efficiency declines, at this moment generally filter operation need be interrupted, change filter element or take out cleaning, not only time-consuming but also bothersome, affect treatment effeciency, there is a kind of water filter of automatic backwash at present, automatically can be cleaned filter core by washing away of the clear liquid of water purifier filtration, the filter of this self-cleaning can only clean the residual dirt of filter core inner chamber, dirt for other position of filter interior has no idea to clean, the bottom of filter housings especially, a large amount of dirts is deposited in the process of filtering, long-term deposition can corrode the inwall in filtrate chamber, shorten the service life of filter, frequently clean need again a large amount of artificial, so not only time-consuming, effort, also have a strong impact on the efficiency of work.
Summary of the invention
The invention provides a kind of bottom cleaning device of filter, object solves prior art problem, provides one both to save time, laborsaving, the cleaning device of high-efficiency cleaning filter again.
The present invention deal with problems adopt technical scheme be:
A kind of bottom cleaning device of filter, there is filter core, gap is provided with between the sidewall of filter core and housing and telophragma, gap UNICOM composition filtrate chamber, the top of housing is provided with filtrate (liquid, filtrate (liquid and filtrate chamber UNICOM, filter core is fixed on the telophragma of filter, telophragma is set on main shaft, main shaft connecting drive device, drive unit is located at the top of filter housings, the bottom of housing is provided with filtrate import, filtrate import and filter core UNICOM, the bottom that sewage draining exit is located at housing is connected with magnetic valve, differential pressure controller is provided with in housing, telophragma is provided with anti-cleaning device, it is characterized in that: the bottom of described housing is provided with expansion link, expansion link is by main shaft connecting drive device, the top of expansion link is provided with support frame, support frame connects cleaning brush, the radius of cleaning brush is not less than the radius of filter core, support bar is equipped with between every root support frame and sliding sleeve, the two ends of support bar are hinged with support frame and sliding sleeve respectively, sliding sleeve is slidably located in outside expansion link.
Beneficial effect of the present invention: because the present invention's promotion sliding sleeve when expansion link extends is close to support frame, simultaneously, support bar is also close to support frame under the drive of sliding sleeve, and support frame is promoted by support bar and opens, and makes the inwall bottom cleaning brush energy contacts filter can clean the dirt being attached to filter bottom, cleaning brush is opened when in use, can draw in when not using, not affect the normal work of filter, namely save time, laborsaving, operating efficiency is high again.
Accompanying drawing explanation
Fig. 1 is sectional structure chart of the present invention;
Fig. 2 is cleaning device of the present invention profile in a state of use.
In figure: 1, filter core; 2, telophragma; 3, main shaft; 4, drive unit; 5, housing; 6, filtrate import; 7, filtrate (liquid; 8, sewage draining exit; 9, magnetic valve; 10, differential pressure controller; 11, anti-cleaning device; 12, expansion link; 13, filtrate chamber; 14, support frame; 15, cleaning brush; 16, support bar; 17, sliding sleeve.
Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the invention will be further described.
As Fig. 1, the bottom cleaning device of a kind of filter shown in Fig. 2, there is filter core 1, gap is provided with between the sidewall of filter core 1 and housing 5 and telophragma 2, gap UNICOM composition filtrate chamber 13, the top of housing 5 is provided with filtrate (liquid 7, filtrate (liquid 7 and filtrate chamber 13 UNICOM, filter core 1 is fixed on the telophragma 2 of filter, telophragma 2 is set on main shaft 3, main shaft 3 connecting drive device 4, drive unit 4 is located at the top of filter housings 5, the bottom of housing 5 is provided with filtrate import 6, filtrate import 6 and filter core 1 UNICOM, the bottom that sewage draining exit 8 is located at housing 5 is connected with magnetic valve 9, differential pressure controller 10 is provided with in housing 5, telophragma 2 is provided with anti-cleaning device 11, the bottom of described housing 5 is provided with expansion link 12, expansion link 12 is by main shaft 3 connecting drive device 4, the top of expansion link 12 is provided with support frame 14, support frame 14 connects cleaning brush 15, the radius of cleaning brush 15 is not less than the radius of filter core 1, support bar 16 is equipped with between every root support frame 14 and sliding sleeve 17, the two ends of support bar 16 are hinged with support frame 14 and sliding sleeve 17 respectively, sliding sleeve 17 is slidably located in outside expansion link 12, sliding sleeve 17 is promoted close to support frame 14 when expansion link 12 extends, simultaneously, support bar 16 is also close to support frame 14 under the drive of sliding sleeve 17, support frame 14 is promoted by support bar 16 and opens, make the inwall bottom cleaning brush 15 energy contacts filter, be convenient to the clean dirt being attached to filter bottom, cleaning brush 15 is opened when in use, can draw in when not using, do not affect the normal work of filter, namely save time, laborsaving, operating efficiency is high again.
When just having started to filter, the pressure in the filter core chamber of filter keeps constant substantially, liquid from the inner chamber of filter core 1 outwardly, along with the carrying out of the work of filtration, entrained solid impurity is by the inner surface dammed at filter core, interior exocoel pressure reduction is caused to raise, filtration resistance increases gradually, when interior exocoel pressure reduction exceedes a certain setting value of differential pressure controller, differential pressure controller sends signal, control electric motor starting, and drive drive unit 4 to run, drive unit 4 drives anti-cleaning device 11 to rotate, drive unit 4 drives expansion link 12 to extend, and it is close to support frame 14 to promote sliding sleeve 17, sliding sleeve 17 also drives support bar 16 close to support frame 14 simultaneously, support bar 16 is in the process close to support frame 14, support frame 14 is promoted by support bar 16 and opens, make the inwall of the bottom of cleaning brush 15 energy contacts filter, the dirt of the inwall being attached to filter bottom can be cleaned, cleaning brush 15 is opened when in use, while cleaning brush 15 is clean, open sewage draining exit 8 from magnetic valve 9 blowdown, after having cleaned, expansion link 12 pulls sliding sleeve 17 to move to the direction away from support frame 14, support bar 16 under the drive of sliding sleeve 17 also to support frame 14 away from, support bar 16 to support frame 14 away from process in, support frame 14 is pulled by support bar 16 and draws in, does not affect normal filtration, so namely saves time, laborsaving, operating efficiency is high again.Also save manpower greatly.
