Water filtering and circulating equipment for drainage engineering, and working method thereof

Abstract

The invention discloses water filtering and circulating equipment for drainage engineering, and a working method thereof. The water filtering and circulating equipment comprises a condenser, a sludgedrying mechanism, a filtering mechanism and a conveying pipe, wherein the filtering mechanism is installed on a supporting frame, the sludge drying mechanism is arranged under the discharging end of the filtering mechanism, the condenser is arranged on one side of the sludge drying mechanism and connected with the condenser, the conveying pipe is arranged under the discharging end of the sludge drying mechanism, the top end of a centrifugal cylinder is rotatably connected with the top surface of a filter box, the bottom end of the centrifugal cylinder is connected with a sewage discharge pipe,the bottom end of the sewage discharge pipe extends out of a transfer box and is rotatably connected with the transfer box, a plurality of groups of filter holes are uniformly formed in the arc-shaped side wall of the centrifugal cylinder and the side wall of the sewage discharge pipe respectively, and a water storage bin is formed between the inner walls of the filter box and the transfer box and the outer wall of the centrifugal cylinder. The equipment of the invention has the advantages that water for drainage engineering is filtered through the centrifugal effect, so that the filtering efficiency is greatly improved, and filtered sludge can be automatically discharged.

Description

technical field [0001] The invention belongs to the technical field of drainage engineering, and relates to a filtration circulation equipment and a working method thereof, in particular to a drainage engineering water filtration circulation equipment and a working method thereof. Background technique [0002] Drainage engineering refers to the project of collecting and discharging human domestic sewage and various waste water in production, redundant surface water and groundwater (lowering the groundwater table). The main facilities include drainage ditches or pipelines at all levels and their ancillary buildings. Depending on different drainage objects and drainage requirements, water pumps or other water lifting machinery, sewage treatment buildings, etc. can also be added. Mainly used in farmland, mines, towns (including factories) and construction sites, etc. [0003] In the prior art, after the filter equipment is used, the sludge still stays in the inside of the filt...

Problems solved by technology

[0004] The purpose of the present invention is to solve the problem that in the prior art, after the filter equipment used is working, the silt still remains in the inside of the filter cartridge, and then, the staff needs to stop the filtering work intermittently, and clean the silt inside the filter cartridge for the next time. Filtering the water for the drainage project causes the filter equipment to not work in a continuous cycle, so as to achieve the effect of non-st
