Sewage filtering detection device

Abstract

The invention relates to the technical field of detection. The invention relates to a sewage filtering detection device. The device comprises a tank, and a water outlet pipe and a water inlet pipe which are arranged on the upper side and the lower side of the left portion of the tank body respectively, a water quality detection sensor assembly is arranged on the water outlet pipe, the lower portion of the tank body is fixedly communicated with a blow-off pipe through a conical tank body, a rotating screw is rotatably connected into the tank body, a filter screen frame capable of moving up anddown is arranged in the tank body, a threaded sleeve in threaded connection with the rotating screw is arranged in the middle of the filter screen frame, and filter screens are arranged on the upper side and the lower side of the filter screen frame. According to the invention, the filter screen frame is convenient to replace, maintenance or cleaning is convenient, sewage passes through the filterscreen frame from bottom to top, the filtering effect is improved, subsequent water quality detection is facilitated, meanwhile, the filtering screen frame and the interior of the tank body are cleaned by spraying and scouring the filtering screen frame and scraping dirt in the tank body through the filtering screen frame, and under the action of the conical tank body, cleaned water and dirt canbe easily discharged out of the tank body.

Description

technical field [0001] The invention relates to the technical field of detection, in particular to a sewage filtration detection device. Background technique [0002] Usually, before the sewage is detected, the sewage needs to be filtered to filter out the impurities in the sewage, so as to avoid the clogging of impurities or the detection of the image water quality sensor. [0003] At present, Chinese Patent No. "201721119736.6" discloses an industrial wastewater filtration and detection device, which includes a wastewater buffer filter, a cleaning scraper and a detection mechanism. The cleaning pipe and the top of the wastewater buffer filter are equipped with a sealing cover through bolts, and the top of the sealing cover is equipped with a driving motor. The inner center of the wastewater buffer filter is vertically installed with a rotating shaft, and the outer ring of the rotating shaft is provided with a filter screen. Although the utility model can easily handle the...
