Technical Field
The utility model belongs to the technical field of the filter, especially, relate to a flat filter.
Background
The flat plate type filter is a simple and practical filter, the common structure is that a filter membrane supporting plate is arranged between an upper cover and a lower support, the upper cover is provided with a liquid inlet pipe, the lower cover is provided with a liquid outlet pipe, when the current flat plate type filter is connected into a pipeline of a hose, the interfaces of the liquid inlet pipe and the liquid outlet pipe are not convenient and fast enough, a connector is not required to be additionally arranged, and a hoop is not required to be additionally arranged.
SUMMERY OF THE UTILITY MODEL
The utility model aims to solve the technical problem that not enough among the above-mentioned prior art is directed at, provide a flat filter, it adopts distinctive feed liquor pipe interface and liquid outlet pipe interface, can directly establish the hose cover on the joint, need not fix convenient and fast again.
In order to solve the technical problem, the utility model discloses a technical scheme is: a flat plate type filter comprises an upper cover, a lower support and a filter membrane supporting plate arranged between the upper cover and the lower support, wherein a liquid inlet pipe connector of the upper cover and a liquid outlet pipe connector of the lower support are symmetrical in structure, the liquid inlet pipe connector of the upper cover is composed of a plurality of connecting parts from top to bottom, and the connecting parts are in frustum shapes with hollow structures.
In the flat plate filter, the upper cover and the lower support are installed in a threaded fit manner, and the lower end of the upper cover is screwed in the lower support; the edge of the filter membrane supporting plate is in sealing fit with the inner wall of the upper cover.
In the flat plate filter, the filter membrane supporting plate is provided with a plurality of liquid leakage holes, the filter membrane supporting plate is provided with a plurality of annular grooves, the diameters of the annular grooves are gradually reduced from outside to inside, and the annular grooves have the same rotary axis.
The upper cover of the flat plate type filter is provided with an exhaust pipe.
In the flat plate type filter, the sealing head of the exhaust pipe is in threaded fit with the pipe body.
Compared with the prior art, the utility model has the following advantage: the utility model discloses a design inlet tube interface and drain pipe interface adopt from the top down structure of constituteing by a plurality of connecting portion, and connecting portion are hollow structure's frustum shape, can be when inserting flat filter on the hose, directly establish the tube head cover of hose on the connecting portion of a plurality of frustum shapes, utilize the hose to have elastic deformation's characteristics, after the hose cover is established, the festival section that lies in every connecting portion rear side end face on the hose can be because of lacking interior support and shrink, thereby with form the effect of cramping between the border of connecting portion rear side end face, thereby it need not fix again after the assurance hose connection, and is convenient and fast.
The technical solution of the present invention is further described in detail by the accompanying drawings and examples.

Detailed Description
As shown in figure 1, the flat plate type filter comprises an upper cover 1, a lower support 2 and a filter membrane supporting plate 3 arranged between the upper cover 1 and the lower support 2, wherein a liquid inlet pipe interface 4 of the upper cover 1 and a liquid outlet pipe interface 5 of the lower support 2 are symmetrical in structure, the liquid inlet pipe interface 4 of the upper cover 1 is composed of a plurality of connecting parts from top to bottom, and the connecting parts are frustum-shaped with a hollow structure.
In this embodiment, the upper cover 1 and the lower holder 2 are installed in a thread fit manner, and the lower end of the upper cover 1 is screwed into the lower holder 2; the edge of the filter membrane supporting plate 3 is in sealing fit with the inner wall of the upper cover 1.
It should be noted that, by adopting the screw-thread fit installation of the upper cover 1 and the lower support 2, the upper cover 1 and the lower support 2 can be matched to compress the filter membrane supporting plate 3, and the installation is convenient and rapid.
In this embodiment, the filter membrane supporting plate 3 is provided with a plurality of leakage holes 6, the filter membrane supporting plate 3 is provided with a plurality of annular grooves 7, the diameters of the annular grooves 7 are gradually reduced from outside to inside, and the annular grooves 7 have the same rotation axis.
The filter membrane can be spread under the action of the annular grooves 7 after being covered by the filter membrane through the plurality of annular grooves 7, and the filtering area is increased.
In this embodiment, the upper cover 1 is provided with an exhaust pipe 8.
In this embodiment, the sealing head of the exhaust pipe 8 is in threaded fit with the pipe body.
The exhaust pipe 8 is arranged to evacuate gas in the flat plate filter after liquid is fed, so that a cavity is avoided.
The utility model discloses during the use, directly establish the tube head cover of hose on the connecting portion of a plurality of frustum shapes of feed liquor pipe interface 4 of upper cover 1 and the play liquid pipe interface 5 of holding in the palm 2 down, utilize the hose to have elastic deformation's characteristics, establish the back when the hose cover, the festival section that lies in every connecting portion rear end face on the hose can support and contract because of lacking in to form the effect of cramping between the border with connecting portion rear end face, thereby need not fix again after guaranteeing the hose connection, convenient and fast.
The above, only be the preferred embodiment of the utility model discloses a it is not right to make any restriction the utility model discloses all according to the utility model discloses any simple modification, change and the equivalent structure change of technical essence to what above embodiment was made all still belong to the technical scheme's of the utility model protection within range.
