To achieve the above object, the utility model employs following technical scheme：A kind of filter for protecting filter plate, bag Filter body, primary filter plate and connecting portion are included, the filter body has inner chamber, water inlet and delivery port, the water inlet Mouth and delivery port connect with the inner chamber, and the filter body is communicated with the breach of the inner chamber, and the connecting portion can seal Block up the breach and slided on the breach, the primary filter plate is connected with rod member, and the first spring, institute are wound with the rod member The first sliding channel that filter body is provided with the rod member is stated, the end of first spring is connected to described first and slided In vias inner walls, first sliding channel corresponds to the second sliding channel that the connecting portion is provided with, and second slip is logical Slide bar is placed with road, the rod member is provided with the suction unit that can hold the slide bar, and the connecting portion is provided with secondary filter plate, institute Secondary filter plate is stated on the right side of the primary filter plate and described in, on the left of the delivery port, the filter body is provided with Montant, is wound with second spring on the montant, and the second spring upper end is connected with pressing plate, and the pressing plate primary is filtered positioned at described Below plate and secondary filter plate.

Further, the filter body inwall is provided with the auxiliary member with cross aisle, is set on the filter body Have a perforation, the primary filter plate is connected with the first screw rod that can pass through the perforation, and the pressing plate is provided with the second screw rod, the The cross aisle that one screw rod is each passed through the auxiliary member with second screw rod is engaged.

Compared to prior art, the utility model has the advantages that：The utility model is when on the primary filter plate When attachment influences the primary filter plate too much, in the case where current are constant, hydraulic pressure can increase, described in the more blockings of attachment Primary filter plate is more pressed in, and hydraulic pressure is bigger, promotes the primary filter plate to move right the slide bar from described when hydraulic pressure increases One sliding channel all slips into second sliding channel, then the connecting portion falls under gravity hits lower section The pressing plate makes partial raw water pass through the secondary filter plate directly below from the primary filter plate, is finally arranged from the delivery port Go out, so as to protect the primary filter plate.

Further advantage, target and feature of the present utility model embody part by following explanation, and part will also pass through Research of the present utility model and practice are understood by the person skilled in the art.

Brief description of the drawings

Fig. 1 is a kind of filter structure schematic representation for protecting filter plate of the utility model.

Embodiment

In order that technological means, creation characteristic, reached purpose that the utility model is realized more understand and are easy to acting on Understand, the utility model is further elaborated with reference to the accompanying drawings and detailed description：

The utility model proposes a kind of filter for protecting filter plate, including filter body 1, primary filter plate 2 and connection Portion 3, the filter body 1 have inner chamber, water inlet 4 and delivery port 5, and the water inlet 4 and delivery port 5 connect with the inner chamber Logical, the filter body 1 is communicated with the breach of the inner chamber, and the connecting portion can block the breach and in the breach Upper slip, the primary filter plate 2 are connected with rod member 9, and the first spring 10 is wound with the rod member 9, is set on the filter body 1 There is the first sliding channel of the rod member 9, the end of first spring 10 is connected on the first sliding channel inwall, institute State the first sliding channel and correspond to the second sliding channel 12 that the connecting portion 3 is provided with, placed in second sliding channel 12 There is slide bar 11, the rod member 9 is provided with the suction unit that can hold the slide bar 11, and the connecting portion 3 is provided with secondary filter plate, described Positioned at the primary right side of filter plate 2 and described in, the left side of delivery port 5, the filter body 1 is provided with secondary filter plate Montant 8, second spring 7 is wound with the montant 8, the upper end of second spring 7 is connected with pressing plate 6, and the pressing plate 6 is positioned at described Primary filter plate 2 and the lower section of secondary filter plate 3.

The utility model is when attachment influences the primary filter plate too much on the primary filter plate, in the feelings that current are constant Under condition, hydraulic pressure can increase, and the more blocking primary filter plates of attachment are more pressed in, and hydraulic pressure is bigger, and institute is promoted when hydraulic pressure increases State primary filter plate and move right and the slide bar is all slipped into second sliding channel, the connection from first sliding channel Portion falls under gravity and then the pressing plate of shock lower section makes partial raw water be passed through directly below from the primary filter plate The secondary filter plate is crossed, is finally discharged from the delivery port, so as to protect the primary filter plate.

As specific embodiment, the inwall of filter body 1 is provided with the auxiliary member 14 with cross aisle, the filtering Device body 1 is provided with perforation, and the primary filter plate 2 is connected with the first screw rod 13 that can pass through the perforation, set on the pressing plate 6 Have the second screw rod 15, the first screw rod 13 cross aisle of the auxiliary member 14 be each passed through with second screw rod 15 match Close；When the connecting portion 3 is through on first sliding channel and the second sliding channel 12 by the slide bar 11, the pressing plate 6 with described primary 2 times end in contact of filter plate；When pushing down institute during the pressing plate 6 moves down during the connecting portion 3 slides State primary filter plate 2 to move left, when needing that the connecting portion 3 is returned into original state again, adjust first screw rod 13 The pressing plate 6 is driven to lift the connecting portion 3；The connecting portion 3 i.e. cause to fall and break to lowest part, the connecting portion 3 all the time with institute State filter body 1 and close the inner chamber.
