Technical Field

The invention relates to the technical field of filtering devices, in particular to a tray type filtering device.

Background

The tray type filtering device adopts a thin steel plate with holes as a framework of the filtering tray, and a layer of filtering cotton is laid on the framework. The sewage containing large granular impurities to be treated is directly sprayed on the filter cotton through a water pipe. Because of its simple structure, conveniently change characteristics such as filter pulp, tray formula filter equipment commonly uses in belt filter equipment and sewage collection pond.

The applicant has found that the prior art has at least the following technical problems: although the tray formula filter equipment that adopts at present stage simple structure, nevertheless because pending water is direct to be spouted on filtering the cotton, not only easily lead to sewage to splash, large granule impurity all stops basically in spraying the contact area moreover for filter the cotton utilization ratio is extremely low, and the filter effect is poor.
