Description

Filter plate unit

Technical field

The utility model is related to the dehydration of sludge treatment field, filter plants, and in particular to a kind of filter plate unit.

Background technology

Filter press is generally used in sludge treatment field, and to treated, mud is dehydrated, and filter press includes mainly multilayer The filter plate unit of fitting setting and upright placement constitutes filter plates, and the concave region of adjacent filter plate unit side encloses each other The mud chamber for accommodating mud is formed, the feed opening being mutually communicated, outermost feed opening and confession are equipped on each filter plate unit Material pump connection, crossing on water plate for two adjacent filter plate units are both provided with filter cloth, and the space between two filter clothes constitutes mud chamber.Press filtration When, it is first pressed to filter plates with hydraulic cylinder, the circumferential surface of the press box of each filter plate unit sides adjacent is made to be bonded the sealing for implementing mud chamber, Then mud is poured into mud intracavitary with charging pump, mud fills mud chamber one by one from the feed opening of one end, and then hydraulic cylinder continues It presses, the spacing between two press boxes in same filter plate unit becomes smaller, and the distance between water plate face of crossing of mud chamber gradually tapers up, and makes Moisture in mud passes through filter cloth to enter in the runner of water plate to flow out from the gutter channel opened up on press box again, and dry mud Cake then stays between two filter clothes.After moisture spilling, the gradual pressure release of hydraulic cylinder, each filter plate unit is gradually disengaged, entire to press Process is filtered to complete.

As illustrated in fig. 1 and 2, filter plate unit in the prior art include the first and second trim ring 1,2, the first and second trim ring 1,2 it Between be provided with elastic support unit 3, the first and second filter plate 4,5 is placed in the first and second trim ring 1,2 circle cavity region and the first and second filter Plate 4,5 is connected, the spacing block set 6 being respectively set on the first and second trim ring 1,2 and the first and second filter plate 4,5 cooperation limitation first and second Trim ring 1,2 continues to detach under the action of elastic force, spacing block set 6 will 3 elastic force of elastically supported unit effect, the limit Convex block 6 is easy to damage, and the case where the first and second trim ring 1,2 falls off occurs and occurs, causes filter plate unit that can not be continuing with.

Utility model content

The purpose of this utility model is to provide a kind of filter plate unit, ensures the structural strength of filter plate unit entirety, extends filter The service life of plate unit.

To achieve the goals above, the technical solution that the application uses for：A kind of filter plate unit, including the first and second press box, Elastic support unit is provided between first and second press box, the first and second filter plate body is placed in the first and second press box frame cavity region, First filter plate body is an integral structure with the first press box, and the second filter plate body is fixed in the first filter plate body.

Compared with prior art, the technique effect of the utility model is：First filter plate body is set as one with the first press box Body formula structure, the second filter plate body are fixed in the first filter plate body, are squeezed again after two filter plates unit superposition adjacent in this way, Spacing between two press boxes becomes smaller, and the distance between water plate face of crossing of mud chamber gradually tapers up, you can the extruding for completing mud is not necessarily to Position limiting structure is set on the first and second press box, ensures the structural strength of filter plate unit entirety, extend filter plate unit uses the longevity Life.

Specific implementation mode

It is described in further detail with reference to Fig. 3 to 9 pairs of the utility model.

A kind of filter plate unit, including the first and second press box 11,12 are provided with resilient support between first and second press box 11,12 Unit 30, the first and second filter plate body 21,22 be placed in the first and second press box 11, in 12 frame cavity regions, the first filter plate body 21 with First press box 11 is an integral structure, and the second filter plate body 22 is fixed in the first filter plate body 21.

In said program, the first filter plate body 21 is an integral structure with the setting of the first press box 11, the second filter plate body 22 It is fixed in the first filter plate body 21, is squeezed again after two filter plates unit superposition adjacent in this way, the spacing between two press boxes becomes Small, the distance between water plate face of crossing of mud chamber gradually tapers up, you can the extruding of mud is completed, without in the first and second press box 11,12 Upper setting position limiting structure not only ensures the structural strength of filter plate unit entirety, extends the service life of filter plate unit, and prepare When single filter plate unit, after being connected by elastic support unit 30 between the first and second press box 11,12, directly by the second filter plate sheet Body 22 is fixed in the first filter plate body 21, and filter plate unit style is for convenient and efficient.

Since the first filter plate body 21 and the first press box 11 are an integral structure, thus, it is only required to by the second filter plate body 22 Periphery wall and 12 inner wall of the second press box constitute sealing cooperation, and osculum 15 is offered on the first and second press box 11,12 bottom walls, It thus is avoided that the sewage being press-filtered out contacts post-etching elastic support unit 30 with elastic support unit 30, extends elastic support unit 30 service life not only facilitates laying in addition, the application only needs to seal the second filter plate body 22 and the second press box 12, and And improve the structural strength of entire press filtration unit.

Further, sealing ring 14 is set between 12 inner wall of second filter plate body, 22 periphery wall and the second press box.

The elastic support unit 30 includes the die springs 31 being arranged between the first and second press box 11,12 opposite side end faces, Die springs 31 are provided with compression spring 32, the first and second pressure between the circumferential uniform intervals arrangement of press box 10, two adjacent die springs 31 The framework of frame 11,12 can uniform stressed, the press filtration effect of sludge is improved, in addition, 31 generally rectangular cross-section mold bullet of die springs Spring, die springs 31 are small, elasticity is good, rigidity is big, long lifespan.

Filter plate unit is placed in rack for convenience, the first and second press box 11,12 is Q-RING cushion, the first and second pressure 11,12 opposite two side of frame is equipped with lug 16, and 16 lower section of lug is equipped with idler wheel 161, in addition, by the first and second filter plate The center position of ontology 21,22 is provided through the feed opening 23 of filter plate body, and sludge is facilitated to be sent into two adjacent filter plate units The chamber surrounded.

Uniform intervals are provided with pillar 24 in the plate face of first and second filter plate body 21,22, and filter cloth is laid on pillar 24, The water being press-filtered out in this way can swimmingly flow to osculum 15.

Square seal ring 13, two adjacent filter plate lists are provided on the outer end face of first press box 11 and/or the second press box 12 Member forms the chamber of sealing, prevents sludge from leaking.
