A kind of bottom cleaning device of filter

Technical field

The utility model relates to a kind of filter, relates in particular 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, cause that increase falls in filter core internal pressure, filtration resistance increases, filter efficiency declines, at this moment generally need to interrupt filter operation, change filter element or take out and clean, not only time-consuming but also bothersome, affect treatment effeciency, there is at present a kind of water filter of automatic backwash, can automatically clean 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, have no idea to clean for the dirt at other position of filter interior, the bottom of filter housings especially, in the process of filtering, deposit a large amount of dirts, long-term deposition can be corroded 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 utility model provides a kind of bottom cleaning device of filter, and object is to solve prior art problem, provide one both saved time, laborsaving, the cleaning device of high-efficiency cleaning filter again.

The utility model deal with problems adopt technical scheme be:

A kind of bottom cleaning device of filter, there is filter core, between the sidewall of filter core and housing and telophragma, be provided with gap, 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, in housing, be provided with differential pressure controller, 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, between every support frame and sliding sleeve, be equipped with support bar, the two ends of support bar are hinged with support frame and sliding sleeve respectively, sliding sleeve is slidably located in outside expansion link.

The beneficial effects of the utility model: to promote sliding sleeve close to support frame when expansion link extends due to the utility model, simultaneously, support bar is also close to support frame under the drive of sliding sleeve, the supported bar of support frame promotes and opens, make the inwall of the contacted filter of cleaning brush energy bottom can clean the dirt that is attached to filter bottom, cleaning brush is opened when in use, when use, can draw in, do not affect the normal work of filter, save time, laborsaving, operating efficiency is high again.

Accompanying drawing explanation

Fig. 1 is sectional structure chart of the present utility model;

Fig. 2 is the profile of the utility model cleaning device under use state.

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.

The specific embodiment

Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.

As Fig. 1, the bottom cleaning device of a kind of filter shown in Fig. 2, there is filter core 1, between the sidewall of filter core 1 and housing 5 and telophragma 2, be provided with gap, gap UNICOM composition filtrate chamber 13, the top of housing 5 is provided with filtrate (liquid 7, filtrate (liquid 7 and filtrate chamber 13 UNICOMs, filter core 1 is fixed on the telophragma 2 of filter, telophragma 2 is set on main shaft 3, main shaft 3 connecting drive devices 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, in housing 5, be provided with differential pressure controller 10, 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 devices 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, between every support frame 14 and sliding sleeve 17, be equipped with support bar 16, 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, when extending, expansion link 12 promotes sliding sleeve 17 close to support frame 14, simultaneously, support bar 16 is also close to support frame 14 under the drive of sliding sleeve 17, the supported bar 16 of support frame 14 promotes and opens, make the inwall of the cleaning brush contacted filter of 15 energy bottom, be convenient to the clean dirt that is attached to filter bottom, cleaning brush 15 is opened when in use, when use, can draw in, do not affect the normal work of filter, 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 outwards flows from the inner chamber of filter core 1, along with the carrying out of the work of filtration, the entrained solid impurity inner surface at filter core that dammed, cause that interior exocoel pressure reduction raises, filtration resistance increases gradually, in the time that 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 move, 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 close process of support frame 14, the supported bar 16 of support frame 14 promotes and opens, make the inwall of the bottom of the contacted filter of cleaning brush 15 energy, can clean the dirt of the inwall that is attached to filter bottom, cleaning brush 15 is opened when in use, when cleaning brush 15 is clean, open sewage draining exit 8 from magnetic valve 9 blowdowns, after having cleaned, expansion link 12 pulls sliding sleeve 17 to the direction motion 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, the supported bar 16 of support frame 14 pulls and draws in, does not affect normal filtration, so saves time, laborsaving, operating efficiency is high again.Also save greatly manpower.
