The cleaning device is provided with a filter core, wherein gaps exist between the filter core and a side wall of a shell and between the filter core and a middle disc and are communicated to form a filtrate cavity, a filtrate outlet is arranged at the upper part of the shell and is communicated with the filtrate cavity, the filter core is fixed on the middle disc of the filter, the middle disc is sheathed on a main shaft which is connected with a driving device, the driving device is arranged at the top part of the filter shell, a filtrate inlet is formed at the lower part of the shell and is communicated with the filter core, a drainage opening is arranged at the bottom of the shell and is connected with a solenoid valve, and a differential pressure controller is arranged in the shell; the cleaning device for the filter core is characterized in that the inner surface of the filter core is flat, a scraping plate is arranged at the top part of the filter core, the edge of the scraping plate pushes against the inner wall of the filter core, the scraping plate is connected with the top part of the filter core by an expansion link, the expansion link is connected with the driving device by the main shaft; after the filter core is blocked, the driving device drives the scraping plate to move up and down; and the edge of the scraping plate removes dirt attached to the inner wall of the filter core when the scraping plate moves up and down.

Description

A kind of cleaning device of filter element

Technical field

The utility model relates to a kind of filter, relates in particular to a kind of cleaning device of filter element.

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, this self-cleaning is not only wasted water, that cleans is unclean yet, especially the obstinate impurity that remains in filter medium surface, can not get effective washing.

Summary of the invention

The utility model provides a kind of cleaning device of filter element, and object is to solve prior art problem, provide one both saved time, laborsaving, the cleaning device of the filter element of high-efficiency cleaning again.

The utility model deal with problems adopt technical scheme be:

A kind of cleaning device of filter element, 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, it is characterized in that: the inner surface of described filter core is smooth, the top of filter core is provided with scraping disc, the inwall of the edge contact filter core of scraping disc, scraping disc is connected with the top of filter core by expansion link, expansion link is by main shaft connecting drive device.

The sharp edges of described scraping disc.

Described scraping disc is provided with several through holes.

The beneficial effects of the utility model: because filter core of the present utility model top is provided with scraping disc, stop up rear drive equipment at filter core and drive scraping disc to do upper and lower motion, in the process moving up and down at scraping disc, the edge of scraping disc is by the dirt removal being attached on filter core inwall.

Brief description of the drawings

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

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, scraping disc; 12, expansion link; 13, filtrate chamber.

Detailed description of the invention

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

A kind of cleaning device of filter element as shown in Figure 1, 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, the inner surface of described filter core 1 is smooth, the top of filter core 1 is provided with scraping disc 11, the sharp edges of scraping disc 11, in the card of scraping disc 11, be provided with several through holes, the inwall of the edge contact filter core 1 of scraping disc 11, scraping disc 11 is connected with the top of filter core 1 by expansion link 12, expansion link 12 is by main shaft 3 connecting drive devices 4, stopping up rear drive equipment 4 at filter core 1 drives scraping disc 11 to do upper and lower motion, in the process moving up and down at scraping disc 11, the edge of scraping disc 11 is by the dirt removal being attached on filter core 1 inwall.

Along with the carrying out of filter process, the impurity that is trapped in cartridge surface will increase, cause water filter water inlet and delivery port pressure differential to increase, utilize the setting value of differential pressure controller 10 to measure the chocking-up degree of filter core, provide the signal of telecommunication simultaneously, realize mechanism's automated cleaning and scrub, the setting value of differential pressure controller can be adjusted according to actual needs.

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, drive drive unit 4 to move, drive unit 4 drives scraping disc 11 to do upper and lower motion, the edge of scraping disc 11 is by the dirt removal being attached on filter core 1 inwall, in clean, open sewage draining exit 8 from magnetic valve 9 blowdowns.
