Abstract

The utility model relates to a filter device with two filter elements. The device is provided with the filter elements, wherein gaps are arranged between the filter element and the side wall of a shell and between the filter element and a central disc and are communicated to form a filtrate chamber; a filtrate outlet is formed on the upper part of the shell and is communicated with the filtrate chamber; each of the filter elements is fixedly arranged on the middle disc of the filter, the middle disc sleeves a main shaft, the main shaft is connected with a driving device, the driving device is arranged at the top of the shell of the filter, a filtrate inlet is arranged on the lower part of the shell and is communicated with each of the filter elements, a drain outlet is arranged at the bottom of the shell and is connected with an electromagnetic valve, and the shell is internally provided with a differential pressure controller; a backwashing device is arranged on the middle disc, and the filter elements consist of a coarse filter element and a fine filter element, so that the quality of the liquid filtered by the filter elements can be greatly improved. Dirt in large size is intercepted during coarse filtration to prevent the dirt from blocking the filter holes of the fine filter element, thereby prolonging the service life the fine filter element. The fine filter element is fixedly arranged on the middle disc and is internally sleeved with the coarse filter element which is locked on the middle disc, and the bottom of the coarse filter element is communicated with the filtrate inlet.

Description

The filter of a kind of pair of filter core

Technical field

The utility model relates to a kind of filter, relates in particular to the filter of a kind of pair of filter core.

Background technology

In industrial filter, major part is that single-stage is filtered, the filtrate quality that single-stage filters out is general, the suspension of the inside in also can more residual sewage, iron ion and colloid thing etc., want to obtain that filtrate that quality is higher needs the filter opening of filter core to arrange is less, filter core is easy to be stopped up by dirt in the process of work, make the Efficiency Decreasing filtering, if filter opening setting is large, can not ensure the quality of filtrate, and the filter core of little filter opening is short service life, need clean frequency high, in clean process, need a large amount of manpowers, also need to stop the work of filtration simultaneously, the inefficiency of so not only filtering, also time-consuming, effort.

Summary of the invention

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

The utility model deal with problems adopt technical scheme be:

The filter of a kind of pair of filter core, 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: filter core is made up of coarse filtration filter core and essence filter filter core, essence filter filter core is installed on telophragma, in essence filter filter core, be arranged with coarse filtration filter core, coarse filtration filter core is fastened on telophragma, the bottom of coarse filtration filter core and filtrate import UNICOM.

The filter opening of described coarse filtration filter core is greater than the filter opening of essence filter filter core.

The beneficial effects of the utility model: can greatly improve the quality of the liquid of filter element filtering because the utility model adopts the structure of two filter cores, simultaneously, the filtration that adopts big or small filter opening to combine, can in coarse filtration, be about to larger dirt interception, prevent that it from stopping up the filter opening of essence filter filter core, extends the service life of essence filter filter core, reduce the use cost of essence filter filter core, the operating efficiency that improves essence filter filter core, reduces artificial workload, saves time, laborsaving.

Brief description of the drawings

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

Fig. 2 is the cross section structure schematic diagram of the utility model filter core.

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, coarse filtration filter core; 13, essence filter filter core.

Detailed description of the invention

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

As Fig. 1, the filter of a kind of pair of filter core 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, filter core 1 is made up of coarse filtration filter core 12 and essence filter filter core 13, essence filter filter core 13 is installed on telophragma 2, in essence filter filter core 13, be arranged with coarse filtration filter core 12, coarse filtration filter core 12 is fastened on telophragma 2, the bottom of coarse filtration filter core 12 and filtrate import 6 UNICOMs.

The filter opening of described coarse filtration filter core 12 is greater than the filter opening of essence filter filter core 13.

When filter is in the time working, filtrate enters filter from filtrate import 6, then in the coarse filtration filter core 12 of inflow and filtrate import 6 UNICOMs, the dirt that volume is greater than the filter opening that coarse filtration filter core 12 is provided with by filtration by coarse filtration filter core 12 is held back, the filtrate that filters out large volume dirt enters in the filter core chamber of essence filter filter core 13, again by the filtration of essence filter core 13, to remain in through the suspension in the filtrate of coarse filtration, being trapped in essence filter filter core chamber of the dirts such as iron ion and colloid thing, the cleaner liquid flowing in filtrate chamber 13 is got rid of by filtrate (liquid 7, enter gathering-device.

Dirt residual in the cleaner liquid filtering by two filter cartridge constructions greatly reduces, improve the quality of the cleaner liquid filtering, meanwhile, the filtration that adopts big or small filter opening to combine can be about to larger dirt interception in coarse filtration, prevent that it from stopping up the filter opening of essence filter filter core, extend the service life of essence filter filter core, reduce the use cost of essence filter filter core, improve the operating efficiency of essence filter filter core, reduce artificial workload, save time, laborsaving.
