Abstract
Description
Technical Field
[0001] This utility model relates to the field of municipal wastewater technology, and in particular to a municipal wastewater sludge removal device. Background Technology
[0002] Municipal wastewater is a type of water source with highly variable water quality, making it very difficult to treat. The concentrations of total dissolved solids, COD, BOD, total silica, ammonia, and some other pollutants change very frequently. In addition, the wastewater before treatment contains high concentrations of organic matter and microorganisms, so it requires specialized wastewater treatment equipment to treat it.
[0003] A search revealed a municipal sewage treatment device with a slag removal mechanism under publication number CN219567719U, relating to the field of sewage treatment technology. The device includes a mixing tank, a slag removal box mounted on its upper surface, an inlet pipe on the upper surface of the slag removal box, and two symmetrically distributed through slots at the connection between the slag removal box and the mixing tank. A first crushing roller and a second crushing roller are rotatably connected to the inner surface of the slag removal box. A second motor is mounted on the bottom surface of the mixing tank, and a third rotating shaft is fixedly connected to the output end of the second motor. A rotating roller is fixedly connected to the surface of the third rotating shaft, and a stirring roller is fixedly connected to the surface of the rotating roller. This invention improves sewage treatment efficiency through the arrangement of the slag removal box, the first crushing roller, and the second crushing roller. The fixed block, movable block, and scraper prevent long-term accumulation of stains in the sewage on the inner wall of the mixing tank, thus facilitating subsequent cleaning of the inner wall of the mixing tank.
[0004] Although the above-mentioned scheme, with its fixed blocks, movable blocks, and scrapers, effectively prevents the long-term accumulation of sludge in the sewage on the inner wall of the mixing tank, thus facilitating subsequent cleaning of the mixing tank's inner wall, some sludge blocks are not sufficiently crushed, and the discharged sewage still contains some sludge, resulting in insufficient sludge removal. Therefore, we propose a municipal sewage sludge removal device. Utility Model Content
[0005] The main purpose of this utility model is to provide a municipal sewage sludge removal device, which solves the problem that some sludge blocks are not fully crushed, and the discharged sewage still contains some sludge, resulting in insufficient sludge removal effect, by setting a mixing unit and a filtration unit.
[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0014] Preferably, the cleaning component includes a fixed box installed at the end of the stirring rod away from the rotating shaft, a connecting spring installed on the bottom wall of the fixed box, a connecting plate installed at the end of the connecting spring, and a cleaning brush installed on the side wall of the connecting plate opposite to the connecting spring.
[0015] Preferably, the drain component includes a movable seat mounted on the circumferential side of the threaded shaft and a cleaning brush mounted on the bottom of the movable seat.
[0016] Preferably, the filtration unit further includes a drain outlet opened on the side wall of the treatment tank, and a sealing plate installed inside the drain outlet.
[0017] Compared with the prior art, the present invention has the following beneficial effects:
[0018] In this invention, through the mixing and filtering units, when it is necessary to mix and remove impurities from wastewater, wastewater is added from the feeding hopper, and the impurities in the wastewater are crushed by the crushing roller. Subsequently, under the action of gravity, the crushed impurities fall into the treatment tank. At the same time, a biological enzyme catalyst is added to the treatment tank, and the second drive motor drives the rotating shaft to rotate. The rotating shaft fully mixes and reacts the impurities with the biological enzyme catalyst, thereby achieving the catalytic removal of impurities from the wastewater. When it is necessary to discharge the treated wastewater, the filter plate filters and separates the reacted wastewater. The unreacted sludge remains on the top of the filter plate, and the treated wastewater is located below the filter plate. After opening the regulating valve, the treated wastewater can be discharged from the drain pipe. When it is necessary to discharge the sludge, the sealing plate is opened, and the third drive motor drives the threaded shaft to rotate. At this time, the sludge discharge component moves along the threaded shaft, and the cleaning brush discharges the sludge located above the filter plate from the drain port, thereby achieving the separation and discharge of sludge and wastewater and improving the sludge removal effect of wastewater treatment.
