Abstract

The utility model discloses a structure of a filtrate inlet of a filter. The structure of the filtrate inlet of the filter comprises a filter cartridge, wherein gaps are formed among the filter cartridge, the side wall of a shell and middle plates, and are communicated to form a filtrate cavity; a filtrate outlet is formed in the upper part of the shell and communicated with the filtrate cavity; the filter cartridge is fixed on the middle plates of the filter; a spindle is sleeved with the middle plates and is connected with a driving device; the driving device is arranged at the top of the filter shell; the filtrate inlet is formed in the lower part of the shell and communicated with the filter cartridge; a drain outlet is formed in the bottom of the shell and connected with a solenoid valve; a differential pressure controller is arranged in the shell; a backwashing device is arranged on the middle plates; a filtration bag for passing of liquid is clamped in the filtrate inlet; an inlet of the filtration bag is matched with the filtrate inlet; the filtration bag is clamped in the filtrate inlet, so that solid-phase impurities in the filtrate needing to be filtered can be primarily intercepted in the filtration bag; few solid-phase impurities are retained in the liquid filtered by the filtration bag, so that the service life of the filter cartridge can be prolonged and the filtrate with high quality also can be obtained.

Description

The structure of a kind of filter filtrate import

Technical field

The utility model relates to a kind of filter, relates in particular to the structure of a kind of filter filtrate import.

Background technology

In commercial Application, the discharge capacity of sewage is huge, if the solid phase impurity existing in sewage is directly discharged into public sphere without processing, the environment of meeting severe contamination the Nature, some sewage is through processing all right secondary utilization, if be directly discharged into public sphere, not only can environment be produced and be polluted, also can cause the waste of resource, the existing filter that is widely used in industrial filter can make sewage secondary utilization by the filtration of filter core at present, but in the process of filtering, the filter opening of filter core is even stopped up on the surface that the solid matter that filter core is held back can be attached to filter core cavity wall, greatly reduce like this service life of filter core, if need to continue to allow filter core work just must clean filter core, the process of cleaning loses time, also need to employ a large amount of manpowers, filter core stop up serious in renew cartridge more also, improve use cost.

Summary of the invention

The utility model provides the structure of a kind of filter filtrate import, and object is to solve prior art problem, provides a kind of filter efficiency high, cleans simple and convenient, the with low cost filter of filter core.

The utility model deal with problems adopt technical scheme be:

The structure of a kind of filter filtrate import, 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: in the housing of filter, described filtrate import department is arranged with the filter bag that liquid passes through, the import of filter bag coordinates with filtrate import.

The filter bag that described liquid passes through is provided with several through holes, irregular alignment between through hole.

The outlet UNICOM sewage draining exit of the filter bag that described liquid passes through, and be fastened on sewage draining exit.

The beneficial effects of the utility model: because the utility model is arranged with filter bag in filtrate import department, solid phase impurity in the filtrate that needs are filtered that can be preliminary is trapped in filter bag, the solid phase impurity containing in liquid after filtering by filter bag is less, continue to filter by filter core again, not only extend the service life of filter core, can also obtain the cleaner liquid that quality is higher, due to filter bag be active card establish can take off at any time cleaned and changed, filter bag with low cost, easy to clean reduces labour's use.

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, anti-cleaning device; 12, filter bag; 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.

The structure of a kind of filter filtrate import 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 1, be provided with differential pressure controller 10, telophragma 2 is provided with anti-cleaning device 11, in the housing 5 of filter, described filtrate import 6 places are arranged with the filter bag 12 that liquid passes through, the import of filter bag 12 matches with filtrate import 6, the filter bag 6 that liquid passes through is provided with several through holes, irregular alignment between through hole.

The all right UNICOM of the outlet sewage draining exit 8 of the filter bag 12 that described liquid passes through, in cleaning filter blowdown, filter bag 12 can be communicated with magnetic valve 9 by sewage draining exit 8, and the solid phase dirt of holding back in filter bag 12 is got rid of from magnetic valve 9 by sewage draining exit 8.

When filter is in the time working, filtrate enters filter from filtrate import 6, then in the filter bag 12 of inflow and filtrate import 6 UNICOMs, the dirt of solid phase is held back in filtration by filter bag 12, enter in the filter core chamber of filter core 1 through the preliminary filtrate of filtering of filter bag 12, again by the filtration of filter core 1, being trapped in filter core chamber through dirts such as the suspension in the filtrate of coarse filtration, iron ion and colloid things will be remained in, the cleaner liquid flowing in filtrate chamber 13 is got rid of by filtrate (liquid 7, enters gathering-device.

Solid phase dirt residual in the filtrate of filtering by filter bag 12 reduces, can extend greatly again the service life of filter core through the filtration of filter core 1, reduce the manpower that frequent clean filter core is paid, because filter bag 12 is simple in structure, materials'use with low cost, can take out at any time and change or clean, reduce the use cost of filter element cleaning and replacing.
