Abstract

The utility model relates to a plate type filter core. The filter core comprises a filter plate; the middle of the filter plate is provided with a frame; the frame is a rectangular body; the middle of the frame is a clear solution chamber; the outer part of the filter plate is a foul solution chamber; the end part of the frame is provided with a through hole communicated with the clear solution chamber; the periphery of the filter plate is provided with elastic sealing edges; the filter plate is provided with three layers of filter screens; one middle layer of the filter screens is a fine filter layer; both sides of the middle layer of the filter screens are two rough filter supporting layers. The filter core has the advantages of low cost, simple manufacture technology, convenient installation and washing. The utility model can form a plurality of input ports and output ports for meeting the different installing and using requirement. The utility model can be used in reverse direction way.

Description

Board-like filter core

The utility model relates to a kind of filter core of filter.

In the prior art, the filter core of filter is that the glass line is cylindrical and line gap is columniform basically, its shortcoming is the product cost height, complex manufacturing technology, install and clean also trouble, and unlikely reverse use is even after oppositely using, filter core also can can't be removed in cylinder interior because of impurities accumulation and scrap.In addition, this type of filter has only two interfaces of one-in-and-one-out, and input/output port is less, can not satisfy the multiple requirement of installing and using.

The purpose of this utility model is: a kind of board-like filter core is provided, and the product cost of this filter core is low, and manufacture craft is simple, and it is extremely convenient that installation is cleaned, and particularly it can form a plurality of input/output ports, to satisfy the multiple requirement of installing and using.

The technical solution of the utility model is: a kind of board-like filter core, and this filter core comprises filter plate, and the centre of filter plate is provided with framework, and the centre of described framework is clean sap cavity, is the soiling solution chamber outside the filter plate, and the end of framework is provided with the through hole that communicates with clean sap cavity.

The further technical scheme of the utility model is: a kind of board-like filter core, this filter core comprises filter plate, and the centre of filter plate is provided with framework, and described framework is a cuboid, the centre of framework is clean sap cavity, be the soiling solution chamber outside the filter plate, the end of framework is provided with the through hole that communicates with clean sap cavity, and the both sides of framework are curved to be contacted with cylinder body, be provided with the elastic packing limit around the described filter plate, the filter screen of filter plate has three layers at least, and the centre is the fine filtering layer, and both sides are the coarse filtration supporting layer.

The utility model has the advantages that:

1. because filter core of the present utility model is made up of the filter plate on framework and both sides, make that the manufacture craft of this product is simple, it is also extremely convenient that installation is cleaned.

2. when this filter core used, liquid was exported in the through hole of the two ends of framework from the input of filter plate outside, therefore can form a plurality of input/output ports, to satisfy multiple requirement of installing and using.

3. the utility model is forward and reverse can both use, and is made between soiling solution chamber and the clean sap cavity by the pressure drop of filter plate to form pressure differential, and hold-down frame when making the filter plate forward compresses cylinder body in the time of oppositely, and the elastic packing limit of filter plate seals.

4. the utility model can increase the quantity of fine filtering layer in the filter plate, thereby reach different filtration grade requirements according to different situations.

The utility model will be further described below in conjunction with drawings and Examples:

Fig. 1 is a front view of the present utility model;

Fig. 2 is an attached view of the present utility model;

Fig. 3 is the front view of filter plate;

Fig. 4 is the left view of filter plate;

Fig. 5 is the front view of framework;

Fig. 6 is the vertical view of framework.

Wherein: 1. filter plate; 2. framework; 3. clean sap cavity; 4. through hole; 5. elastic packing limit; 6. fine filtering layer; 7. coarse filtration supporting layer; 8. cylinder body.

Embodiment: as Fig. 1, Fig. 2, Fig. 3, Fig. 4, Fig. 5, shown in Figure 6, a kind of board-like filter core, this filter core comprises filter plate (1), the centre of filter plate (1) is provided with framework (2), described framework (2) is a cuboid, the centre of framework (2) is clean sap cavity (3), be the soiling solution chamber outside the filter plate (1), the end of framework is provided with the through hole (4) that communicates with clean sap cavity (3),, the both sides of framework (2) are curved to be contacted with cylinder body (8), be provided with elastic packing limit (5) around the described filter plate (1), the filter screen of filter plate (1) has three layers, and the centre is fine filtering layer (6), and both sides are coarse filtration supporting layer (7).Because filter core of the present utility model has the filter plate (1) on cuboid framework (2) and both sides to form, and makes that the manufacture craft of this product is simple, it is also extremely convenient that installation is cleaned; When this filter core used, liquid was from the input of filter plate (1) outside, and output in the two ends through hole (4) of framework (2) therefore can form a plurality of input/output ports, to satisfy multiple requirement of installing and using; The utility model is forward and reverse can both to be used, pressure drop by filter plate (1) makes the soiling solution chamber and forms pressure differential between the sap cavity (3) only, hold-down frame (2) when making filter plate (1) forward compresses cylinder body (8) in the time of oppositely, and the elastic packing limit (5) of filter plate (1) seals; The utility model can increase the quantity of fine filtering layer (6) in the filter plate (1), thereby reach different filtration grade requirements according to different situations.
