Problems solved by technology

Currently, there are two types of secondary filter screen structure disclosed: fixed type and electric rotary type, but there are generally some problems or deficiencies, such as: the disadvantages of the fixed type are mainly that the mesh core is fixed and cannot be rotated, the effect of cleaning dirt is poor, and the mesh is very easy to filter. Blockage, etc.; the disadvantages of the electric rotary type are mainly that the structure is complex and easily damaged, the water resistance is r...

Abstract

The invention discloses a self-rotating clean collecting device, and belongs to the technical field of filtration. The device is characterized by consisting of a main pipeline or an outer shell, a filter screen assembly, a self-rotating scouring scraper assembly, a conical impeller, a rotating shaft, a rear bearing supporting assembly, a rear bearing assembly, a front bearing supporting assembly, a front bearing assembly and an extraction pipe; the self-rotating scouring scraper assembly and the conical impeller are arranged on the rotating shaft positioned at the rotation axis of the conical filter screen assembly, and the rotating shaft is supported and positioned through the front and rear bearing assemblies and generates self rotation under the action of fluid in the main pipeline or the outer shell; the solid substances in the fluid are filtered in a filter screen, collected at the tail part of the filter screen assembly under the combined action of the self-rotating scouring scraper assembly, the conical impeller and the fluid and then extracted from the extraction pipe; and meanwhile, the filter screen assembly keeps clean all the time under the combined action of the self-rotating scouring scraper assembly, the conical impeller and the fluid. The device has good collecting effect, low flow resistance and long service life.

Description

technical field [0001] The invention relates to a self-rotating cleaning and collecting device, especially a self-rotating cleaning and collecting rubber ball device for collecting rubber balls in a water-cooled power station condenser rubber ball cleaning system and keeping the self-rotating cleaning of the rubber ball collecting net, and A self-rotating cleaning and collecting debris device for filtering the debris in the cooling water in the cold source system of the water-cooled power station and maintaining the self-rotating cleaning of the debris filter. Background technique [0002] Water-cooled power station condensers generally have the problem of fouling and fouling during operation, and have a very important impact on the thermal efficiency of the unit and the life of the equipment. Therefore, at present, the rubber balls in the heat exchange tube are generally used to clean or the heat exchange tube is inserted into the rotating element. Descaling and anti-scalin...
