Technical Field
[0001] This utility model relates to the field of filtration devices, and in particular to an activated sludge dewatering filtration device. Background Technology
[0002] Dewatering and filtration devices are high-efficiency equipment used for solid-liquid separation. They quickly remove moisture from materials using mechanical or physical methods and are widely used in chemical, food, environmental protection, and mineral processing industries. Activated sludge dewatering and filtration devices are key equipment in wastewater treatment for thickening and dewatering excess sludge. They reduce the moisture content of sludge mechanically, facilitating transportation and disposal. They feature high automation, large processing capacity, and stable operation, and are widely used in municipal wastewater treatment plants and industrial wastewater treatment, effectively reducing sludge volume and lowering subsequent disposal costs.
[0003] Traditional sludge dewatering and filtration devices generally have a relatively low dewatering effect, and the dewatered sludge tends to accumulate, resulting in relatively low discharge efficiency. Furthermore, traditional sludge dewatering and filtration devices are prone to accumulating sludge at the feed inlet, which can affect the dewatering efficiency of the equipment.
[0004] Therefore, those skilled in the art have provided an activated sludge dewatering and filtration device to solve the problems mentioned in the background art. Utility Model Content
[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing an activated sludge dewatering and filtration device. This device utilizes a stirring plate, auger blades, and agitator plates within a stirring tank to agitate the sludge, effectively preventing sludge buildup and ensuring it can proceed through the dewatering process. The stirring plate continuously pushes the sludge from the bottom into the through-hole, while the auger blades transport the sludge downwards. The agitator plates further agitate the sludge. This mechanism effectively prevents sludge buildup and clumping, significantly improving the device's efficiency.
[0006] To achieve the above objectives, the present invention provides the following technical solution:
[0007] An activated sludge dewatering and filtration device includes a frame, a base fixedly connected to the upper surface of the frame, a support block fixedly connected to the rear end of the upper surface of the base, a housing fixedly connected to the upper surface of the support block, an agitation mechanism provided on the upper surface of the housing, the agitation mechanism including an agitation tank fixedly connected to the upper surface of the housing, a shell fixedly connected to the upper surface of the agitation tank, a first motor fixedly connected to the inner bottom surface of the shell, a first bevel gear fixedly connected to the output end of the first motor, a second bevel gear rotatably connected to the outer wall of the first bevel gear, an agitation column fixedly connected to the lower surface of the second bevel gear, multiple agitation plates fixedly connected to the upper end of the outer wall of the agitation column, auger blades fixedly connected to the middle part of the outer wall of the agitation column, and multiple actuating plates fixedly connected to the lower end of the outer wall of the agitation column.

The agitator plate continuously pushes the sludge at the bottom into the through hole, the auger blades transport the sludge downwards, and the stirring plate stirs the sludge.

After the extruded sludge is dehydrated, the electric push rod creates a gap between the extrusion plate and the dehydration pipe. The second motor continuously rubs and rotates the dehydrated sludge.
