Abstract

The patent of the present invention discloses a spiral mechanical filter for aquaculture water, which includes a front baffle, a rear baffle, a curved screen, a spiral blade type sewage discharge device, a sewage collection tank, a water collection tank and a drainage pipe; the curved screen is provided with Between the front baffle and the rear baffle, a sump is arranged directly under the curved screen, and a drainpipe is arranged on the sump; the spiral blade type sewage discharge device includes a support frame, a bearing, a The main shaft, motor and transmission device; the outer edge of the spiral blade is provided with a brush, and the part of the spiral blade with the brush below the horizontal plane of the main shaft is in contact with the curved screen; the upper end of the curved screen bottom is provided with a water level The sensor can sense the height of the water level in the curved screen, and control the start and stop of the spiral blade accordingly, so as to save energy. The invention has the advantages of simple structure, low maintenance cost and high efficiency, and can improve the performance and service life of the fine filter.

Description

technical field [0001] The invention relates to the field of aquaculture water treatment, in particular to a method for primary filtration of aquaculture water. Background technique [0002] At present, the mechanical facilities used in the field of aquaculture for the removal of solid particles (SS) in wastewater include: drum microfilters, crawler filters, curved screens, in addition to filter bags, filter cotton, sedimentation tanks, sand Various forms of filter devices such as filter tanks. With the country's increasing emphasis on environmental protection, the treatment of large-scale pond aquaculture wastewater is on the agenda. Aquaculture wastewater must be treated to meet the discharge water standards before it can be discharged into rivers, lakes, and oceans. The treatment efficiency of the traditional drum or crawler mechanical filter is generally about 40 tons to 200 tons per hour. The treated water is industrial circulating aquaculture wastewater. The feces an...
