Description

Technical Field

[0001] This utility model relates to the field of sludge dewatering technology, and in particular to a sludge dewatering filter press. Background Technology

[0002] Untreated sludge typically has a moisture content as high as 95%-99%, is bulky and highly mobile, resulting in high direct transportation costs and difficulty in meeting the requirements for landfill, incineration, or resource utilization. Direct discharge or disposal would cause serious harm to the environment, human health, and socio-economic conditions. Sludge dewatering filter presses are solid-liquid separation devices specifically designed for treating sludge with high moisture content. They significantly reduce the moisture content of the sludge, forming a sludge cake with lower moisture content, thus solving the problems of large sludge volume and difficult disposal. They are widely used in municipal, industrial, and environmental protection fields.

[0003] The sludge dewatering filter press achieves efficient solid-liquid separation through a series of precisely designed structures working together. It transforms high-moisture sludge into low-moisture sludge cake. After the plate and frame assembly is compressed, a high-pressure chamber is formed inside, forcing the water in the sludge to pass through the filter cloth and be discharged. The dewatering process is completed through mechanical pressure, filter media and fluid dynamics principles.

[0004] However, sludge dewatering filter presses also have some shortcomings. After dewatering, the filter cloth needs to be cleaned. Traditionally, the filter cloth needs to be disassembled manually for cleaning, which may cause mechanical damage and secondary pollution caused by cleaning wastewater. Fine sludge that is not cleaned properly may clog the filter cloth and shorten the service life of the equipment. Utility Model Content

[0005] To overcome the above deficiencies, this utility model provides a sludge dewatering filter press, which aims to improve the problems of mechanical damage during sludge dewatering and cleaning, secondary pollution caused by untreated cleaning wastewater, and clogging of filter cloth and reduced equipment lifespan caused by uncleaned fine sludge.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a sludge dewatering filter press, comprising a filter frame, a traveling support slidably connected above the filter frame, and a fixing component provided on the traveling support;

[0007] The fixed assembly includes a rinsing bracket, a water sprayer fixedly connected to the lower surface of the rinsing bracket, a cleaning brush fixedly connected to the lower surface of the water sprayer, a water pipe fixedly connected to the upper end of the rinsing bracket, a water tank provided at one end of the water pipe, a second motor threadedly connected to the upper surface of the water tank, a water pump fixedly connected to the output end of the second motor, a gear rotatably connected inside the walking bracket, a rotating shaft fixedly connected inside the gear, and one end of the rotating shaft fixedly connected to the output end of the first motor.

[0008] Furthermore, a filter screen is provided below the filter frame, one end of the filter screen is slidably connected to a bulldozer rod, and one end of the bulldozer rod is fixedly connected to a bucket.

[0009] Furthermore, a water storage box is provided below the filter screen, and support legs are fixedly connected to the four corners of the water storage box.

[0010] Furthermore, a crossbeam is fixedly connected to the upper surface of the support leg.

[0011] Furthermore, a frame is fixedly connected to the upper surface of the crossbeam, and a support frame is slidably connected to the upper surface of the crossbeam.

[0012] Furthermore, a support frame is fixedly connected to both sides of the filter frame, and a pressure plate is provided at one end of the filter frame.

[0013] Furthermore, a thrust plate is fixedly connected to one side of the frame.

[0014] Furthermore, a piston rod is fixedly connected to one side of the clamping plate, a sealing plug is fixedly connected to one side of the piston rod, and a hydraulic cylinder seat is slidably connected to the outer surface of the sealing plug.

[0015] This utility model has the following beneficial effects:

[0016] 1. In this utility model, the automatic cleaning device pumps water from the water storage tank into the water pipe through a water pump. The water flows to the rinsing bracket and is sprayed out from the lower sprayer. Together with the cleaning brush, the filter cake is brushed off, and the filter cake and residual sludge on the filter cake are washed away, achieving the effect of automatically cleaning the filter cloth. This solves the problems of mechanical damage and incomplete cleaning that may occur with manual cleaning.

[0017] 2. In this utility model, the equipment uses a filter screen to trap solid particles above the water storage box, while the liquid flows directly in. The dewatered sludge is then produced by a bucket for processing, which facilitates filter cake treatment and achieves the effect of treating cleaning wastewater, solving the problem of difficult filter cake cleaning and secondary pollution caused by cleaning wastewater.
