Abstract

The utility model relates to a filter with a replaceable filter core. The filter 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, a groove is formed in the middle disc at a position where the filter core is arranged, a bulge is formed at the end part of the filter core and is matched with the groove in shape and size, the bulge and the groove are in threaded connection; when the filter core needs to be replaced or cleaned, the filter core can be screwed out, a new filter core or the cleaned filter core is screwed on, in this way, complicated steps for replacing the whole filter is avoided, and a risk that the filter core is damaged when replaced or cleaned can be reduced.

Description

A kind of filter of replaceable cartridge

Technical field

The utility model relates to a kind of filter, relates in particular to a kind of filter of replaceable cartridge.

Background technology

The filter core of the filter using in industrial filter is to be substantially all directly welded on the telophragma of filter, when needing cleaning or filter core to damage, filter core obstruction need to when replacing, must overallly take out, relatively waste time and energy, and the telophragma of filter is set on main shaft, take out pretty troublesomely, structure is more complicated also, takes out frequently the cleaned and changed service life that can reduce filter, improve use cost, cause unnecessary waste.

Summary of the invention

The utility model provides a kind of filter of replaceable cartridge, and object is to solve prior art problem, and a kind of filter element replacing a kind of filter of replaceable cartridge is simply and easily provided.

The utility model deal with problems adopt technical scheme be:

A kind of filter of replaceable cartridge, 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, it is characterized in that: the position that filter core is installed on telophragma is provided with groove, the sidewall of groove is provided with screw thread, the end of filter core is provided with projection, the sidewall of projection is provided with screw thread, shape size and the groove of projection match, projection is connected by thread helix with groove.

The beneficial effects of the utility model: because filter core of the present utility model is that spiral is connected with telophragma, in the time that need to changing or be clean, only filter core spiral need to be backed out filter core, then the filter core of replacement is screwed on again or the filter core after clean is screwed on again, in the time only having part filter core to change and to clean, remaining filter core can work on, can save like this step of integral replacing complexity, can also reduce the risk of changing or cleaning the damage of filter core to filter core, simultaneously, such filter element replacing is convenient, fast, only change the filter core that needs replacement and clean, can reduce the wasting of resources that integral replacing causes.

Accompanying drawing explanation

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

Fig. 2 is the decomposition texture schematic diagram that the utility model telophragma is connected with 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, groove; 11, projection; 13, filtrate chamber.

The specific embodiment

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 replaceable cartridge 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, the position that filter core 1 is installed on telophragma 2 is provided with groove 10, the sidewall of groove 10 is provided with screw thread, the end of filter core 1 is provided with projection 11, the sidewall of projection 11 is provided with screw thread, shape size and the groove 10 of projection 11 match, projection 11 is connected by thread helix with groove 10.

In the time that needing to change or be clean, only filter core 1 spiral need to be backed out filter core 1, then the filter core of replacement is screwed on again or the filter core after clean is screwed on again, in the time only needing replacing or cleaning part filter core, the filter core that needs are changed or cleaned takes out, remaining filter core can work on, be unlikely to because cause specific causes stopping production, stop work, simultaneously, can save so the complicated step of the sub-assembly of the whole telophragma of integral replacing and filter core, can also reduce the risk of changing or cleaning the damage of filter core to filter, more renew cartridge is also more convenient, fast, can reduce the wasting of resources that integral replacing causes.

Claims
