Rotary wastewater filtering device capable of automatically discharging residues

Abstract

The invention discloses a rotary wastewater filtering device capable of automatically discharging residues. The device comprises a filtering box body, a base, a support, a sedimentation tank, a variable frequency motor, a water pump and a controller, wherein the filtering box body and the support are both mounted on the base, a filtering cavity is formed in the filtering box body, a hollow rotating shaft extending into the filtering cavity is inserted into the support, the right end of the hollow rotating shaft extends out of the support, a driven belt pulley and a rotating joint are mounted at the right end of the hollow rotating shaft, the other end of the rotating joint is connected with a water inlet pipe connected with the sedimentation tank, the variable frequency motor drives the driven belt pulley to rotate through a driving belt pulley and a drive belt, a first filtering cartridge and a second filtering cartridge which are connected with the hollow rotating shaft are arrangedin the filtering cavity, thread lines and filtering holes are arranged on the first filtering cartridge and the second filtering cartridge, and a washing pipe is mounted on the inner wall of the upperend of the filtering cavity. The rotary wastewater filtering device has the benefits of simple structure and high practicability.

Description

technical field [0001] The invention relates to the technical field of sewage filtering equipment, in particular to a rotary waste water filtering device capable of automatically discharging slag. Background technique [0002] At present, with the development of science and technology, industry and other fields are also making rapid progress, but it has brought about a sharp increase in the amount of industrial sewage. Therefore, the purification of sewage is of great significance to the protection of the environment. Industrial sewage It often contains solid impurities and some harmful substances, which brings great difficulties to the later stage of sewage purification. Traditional water purification uses sedimentation and other methods. This method of purifying sewage is not only time-consuming, but also consumes resources. It is cumbersome to clean up precipitated impurities. , Delay the time of the enterprise, and also greatly increase the production cost of the enterpr...
