Abstract

The invention provides a disc filter comprising a shell, and a plurality of filter blades and collecting pipes which are sequentially fixed inside the shell, wherein each filter blade comprises a rigid skeleton, a piece of filter cloth covering the rigid skeleton, and a filtering-after cavity inside the rigid skeleton, wherein the filter blades are in a disc form; the collecting pipes are sequentially communicated with filtering-after cavities of the plurality of filter blades; the inner diameters of the collecting pipes are gradually increased in the flowing direction of the collecting pipes; the filter blade near an outlet of each collecting pipe and the filter blade far away from the outlet basically have the same volume degree when the collecting pipes provide the certain vacuum degrees, and can balance the workloads of the filter blades. Thus, the service life of the disc filter is prolonged.

Description

Disk filter

Technical field

The present invention relates to filter field, be specifically related to a kind of disk filter.

Background technology

In filter, to have disposal ability large for disk filter, easy to operate, be widely used in light industry field, after the filter of the disk filter using at present, the manifold trunk of liquid does not change at pipe diameter size, there is gradient distribution distribution owing to collecting intraductal pressure, cause each filter leaf operating efficiency different, some filter leafs are scrapped in advance, and some filter leafs are not also fully used.

Summary of the invention

Object of the present invention provides disk filter, solves in above-mentioned prior art problem each filter leaf operating efficiency different.

The invention provides a kind of disk filter, comprise housing, be fixed in turn multiple filter leafs and the manifold trunk of enclosure interior, filter leaf comprises hard skeleton, covers the filter cloth of hard skeleton and the filter rear chamber of hard skeleton inside, filter leaf is disc, manifold trunk is communicated with the filter rear chamber of multiple filter leafs in turn, and on the flow direction of manifold trunk, the internal diameter of manifold trunk progressively increases.

Disk filter provided by the invention is due on the flow direction of manifold trunk, the design that the internal diameter of manifold trunk progressively increases, in the time that manifold trunk provides certain vacuum, near the filter leaf in the exit of manifold trunk with all there is essentially identical vacuum away from the filter leaf in exit, the evenly live load of each filter leaf.Improve the service life of disk filter.

Brief description of the drawings

Fig. 1 is the structural representation of the disk filter of an embodiment of the present invention.

Detailed description of the invention

Below in conjunction with accompanying drawing, disk filter provided by the invention is described in further detail.

As shown in Figure 1, the invention provides a kind of disk filter, comprise housing 1, be fixed in turn multiple filter leafs 2 and the manifold trunk 6 of housing 1 inside, filter leaf 2 comprises hard skeleton 3, covers the filter cloth 4 of hard skeleton 3 and the filter rear chamber of hard skeleton 3 inside, and filter leaf 2 is disc, and manifold trunk 5 is communicated with the filter rear chamber of multiple filter leafs 2 in turn, on the flow direction of manifold trunk 5, the internal diameter of manifold trunk 5 progressively increases.Disk filter provided by the invention is due on the flow direction at manifold trunk 5, the design that the internal diameter of manifold trunk 5 progressively increases, in the time that manifold trunk 5 provides certain vacuum, near the filter leaf 2 in the exit of manifold trunk 5 with all there is essentially identical vacuum away from the filter leaf 2 in exit, the evenly live load of each filter leaf 2.Improve the service life of disk filter.

The above is only optimal way of the present invention; it should be pointed out that to those skilled in the art, without departing from the concept of the premise of the invention; can also make some similar distortion and improvement, within these also should be considered as protection scope of the present invention.
