Abstract
The utility model discloses a sealing cover, which comprises a metal cover board and a rubbery sealing board, and is characterized in that the sealing cover further comprises a press board, the rubbery sealing board is positioned between the metal cover board and the press board, the metal cover board, the rubbery sealing board, and the pressing board are attached through a detachable manner, for example, fixed by screw bolts. Using the sealing cover of the utility model, not only the great sealing effect is provided, break and falling is not likely to occur because the rubbery sealing board is fixed using the pressing board and screw bolts in a detachable manner.
Description
Technical field
The utility model relates to a kind of sealing cover, relates in particular to a kind of filtrate discharge mouth of pipe sealing cover that is applicable to aluminium hydroxide folding band vacuum filter.
Background technique
Adopting the folding belt type vacuum filter to filter in the process of aluminium hydroxide, the filtrate of the filter system that discharges can proper functioning to the filter production capacity, the control of filtering index is extremely important.
The employed sealing of filtrate (liquid of traditional type folding belt type vacuum filter is stamped two kinds, and a kind of is to adopt the full-metallic gland seal, and another kind is to adopt the inboard dress suspension type Rubber washer sealing configuration that increases of metal backup shoe.The shortcoming of first kind of sealing cover is: poor sealing, and degree of vacuum is reduced, influence the filter strainability, the bad control of product index, and metal backup shoe mechanical wear is big, and life cycle is short; The good sealing effect of second kind of sealing cover, its shortcoming is that the leather packing life cycle is short, fixedly shakiness comes off easily, may cause Rubber washer to be sucked vacuum system by system's negative pressure causes row's chimney filter road to stop up, or be discharged from filtrate and pour the filtrate pipeline, result in blockage, influence the normal operation of filtration system.
Summary of the invention
In view of this, the purpose of this utility model provides a kind of sealing cover, its good sealing effect and be not easy to damage.
Above-mentioned purpose realizes by following proposal:
A kind of sealing cover, it comprises metal cover board and rubber gasket sheet, it is characterized in that, described sealing cover also comprises pressing plate, described rubber gasket sheet is between described metal cover board and described pressing plate, and described metal cover board, rubber gasket sheet and pressing plate are fixed together by dismountable Placement.
According to above-mentioned sealing cover, it is characterized in that all have through hole on described metal cover board, rubber gasket sheet and the pressing plate, described dismountable Placement is that bolt is fixed by described through hole.
According to above-mentioned sealing cover, it is characterized in that, on described metal cover board, rubber gasket sheet and pressing plate, offer one or more through holes, on each described through hole, all use bolt to fix.
According to above-mentioned sealing cover, it is characterized in that, be connected with hanger on the edge of described sealing cover.
Use sealing cover of the present utility model, existing good sealing effect, and owing to use pressing plate and bolt removably that rubber gasket sheet is fixed, therefore be not easy damage and come off.
Description of drawings
Fig. 1 is the structural representation of sealing cover of the present utility model;
Fig. 2 is that sealing cover of the present utility model is fastened on the schematic representation on the mouth of pipe;
Fig. 3 is the schematic representation of sealing cover of the present utility model when opening.
Embodiment
Referring to Fig. 1, the sealing cover that the vacuum filter filtrate mouth of pipe uses comprises metal cover board 2, rubber gasket sheet 3 and pressing plate 4, rubber gasket sheet 3 is between metal cover board 2 and pressing plate 4, and metal cover board 2, rubber gasket sheet 3 and pressing plate 4 are fixed together by dismountable Placement.
Preferably, the center all has a through hole on metal cover board 2, rubber gasket sheet 3 and pressing plate 4, and dismountable Placement is a bolt, and bolt is fixed by through hole.
Selectively, can also on metal cover board 2, rubber gasket sheet 3 and pressing plate 4, offer a plurality of through holes, on each through hole, all use bolt to fix.
In addition, being connected of the sealing cover and the mouth of pipe can be used hanger 5, and hanger 5 is connected on the edge of sealing cover.
When needs are inhaled vacuum, sealing cover is buckled in the vacuum filter filtrate mouth of pipe (referring to Fig. 2); When the needs discharge opeing, sealing opened get final product (referring to Fig. 3).
