Gathering type solid-liquid separation machine

Abstract

The invention discloses a gathering type solid-liquid separation machine which is fixed in a water channel by a rack. The machine is composed of a filtering device, a residue lifting device and a filtration hole residue cleaning device, wherein the filtering device is a fixed filter plate structure, the width of the filtering device at least accounts for about 50% of the section of passing water, the residue lifting device is arranged on the tail end of the filtering device, the filtration hole residue cleaning device is arranged on the filtering device in a reciprocating manner and used for cleaning filtration holes of a filter plate. The filtering device disclosed by the invention is a fixed filter plate structure, so that the vast majority of flow filtering function is finished by the filter plate, and the filter plate has strong filter capacity, good reliability and is difficult to damage; and according to the gathering type solid-liquid separation machine, barrier residues are naturally gathered in the tail end of a concave arc by utilizing a scouring effect of flow, then the barrier residues are lifted by the residue lifting device which is arranged on the tail end of the concave arc, the width of the residue lifting device only accounts for 20-30% of the section of the passing water of the whole water channel, the scouring force of the flow is greatly reduced, and the gyration running resistance is reduced, thereby greatly reducing the equipment cost and the running energy consumption.

Description

technical field [0001] The invention relates to the field of environmental protection equipment for sewage treatment, in particular to a double-type solid-liquid separator. Background technique [0002] At the water intakes of sewage treatment plants, drinking water intakes, large-scale hydropower stations, comprehensive treatment projects for rivers and lakes, rainwater drainage and sewage lifting pumping stations, etc., equipment such as rotary grid cleaning machines are often used to remove floating objects and sediments from water intakes. The waste is salvaged and removed, and the dirt is squeezed dry, dehydrated, compressed and discharged. However, in the existing grid cleaning machine, the fixed grid bars of the water-passing grid are arranged in the middle of the rotary crawler, which must determine that there is a certain distance between the grid and the river bottom, resulting in a reduction in the water-passing area, especially for channels with low water levels....

AI Technical Summary

Problems solved by technology

[0003] In view of the shortcomings of the above-mentioned existing grid cleaning machine, such as high power, weak strength, and small water passing area, the applicant provides a solid-liquid separator with a reasonable structure, so that it can meet a large amount of water passing, and at the same time, it has various forms. , can be flexibly adapted to a variety of applications
