Description
Technical Field
[0001] This invention relates to the field of water pollution prevention and sludge treatment technology, specifically to an intelligent sludge filtration and treatment device for water pollution prevention. Background Technology
[0002] With the rapid development of my country's wastewater treatment industry, the production of excess sludge has been increasing year by year. Sludge filtration and dewatering, as a key link in water pollution prevention and control, directly affects the compliance and operational efficiency of wastewater treatment systems due to its treatment efficiency and stability. Sludge filtration devices have been widely used in municipal wastewater treatment plants, industrial wastewater treatment plants, and other scenarios, primarily for achieving sludge reduction and stabilization, laying the foundation for subsequent sludge incineration and landfill disposal. However, existing devices still have some problems in use, as follows:
[0003] Existing sludge filtration devices have low levels of intelligence in daily use, relying heavily on manual experience and lacking the ability to monitor multiple parameters across the entire process. They can only monitor a single operating parameter and cannot simultaneously capture changes in key indicators such as pressure, liquid level, and turbidity. Furthermore, existing devices lack precise preprocessing and quantitative analysis of collected parameters, making it difficult to accurately identify potential problems such as pipe corrosion and filter cloth clogging, and unable to quantitatively assess the overall operating status of the device. In addition, the operating parameters of existing devices are mostly fixed settings, unable to dynamically and adaptively adjust according to actual operating conditions. This easily leads to problems such as incomplete dewatering, substandard filtrate, and equipment overload, increasing manpower maintenance costs and exhibiting defects such as delayed fault response and significant energy waste, failing to meet increasingly stringent environmental protection requirements and the need for refined operation and maintenance. Summary of the Invention

[0011] in, This is the minimum safe pressure threshold, which is the minimum effective extrusion pressure of the hydraulic cylinder driving the extrusion plate. If it is lower than this value, the sludge dewatering will be incomplete. This is the maximum safe pressure threshold, which is the highest allowable extrusion pressure of the hydraulic cylinder. Exceeding this value can easily cause the hydraulic cylinder to overload and the filter plate to be damaged. This is the minimum safe threshold for liquid level, i.e. the lowest safe liquid level in the sludge tank and water storage tank.

The maximum safe threshold for torque is the highest allowable load torque of the automatic plate pulling mechanism. Exceeding this value indicates that the mechanism is stuck or overloaded, which may burn out the drive motor. The setting of each threshold is based on the safe operation requirements of the device and the sludge dewatering process standards.

The bottom of the support ears 21 is slidably connected to the top of the support frame 1 to support the filter plates 2 on top of the support frame 1. The outlet pipe 22 is used to discharge the filtrate generated during the filtration process. A sludge tank 3 is fixedly installed at the bottom of the support frame 1, located directly below the filter plates 2, to collect the sludge filter cake that falls after filtration. A water storage tank 4 is installed at the edge of the sludge tank 3, located directly below the outlet pipe 22, to collect the filtrate discharged from the outlet pipe 22. A feed pipe 5 and a hydraulic cylinder 6 are fixedly installed on both sides of the support frame 1, respectively. The hydraulic cylinder 6 is used to transport the sludge to be treated to the internal chambers of each filter plate 2. The hydraulic cylinder 6 is used to provide the driving force for filtration. The output end of the hydraulic cylinder 6 is fixedly installed with a squeezing plate 7, which is used to squeeze each filter plate 2 under the drive of the hydraulic cylinder 6 to achieve sludge dewatering. The top of the support frame 1 is provided with an automatic plate pulling mechanism 8.

The automatic plate pulling mechanism 8 includes an electric guide rail 81 fixedly installed on the top of the support frame 1, an electric guide block 82 slidably connected to the outer wall of the electric guide rail 81, and a plate puller 83 fixedly installed on the top of the electric guide block 82. The electric guide rail 81 and the electric guide block 82 cooperate to drive the plate puller 83 to move along the top of the support frame 1. The plate puller 83 is used to grab and pull the filter plate 2 for separation and unloading. The outer wall of the support frame 1 is installed with a control component 9 to control the coordinated operation of each component.
[0039] During operation, the operator controls the feed pipe 5 through the control component 9 to transport the sludge to be treated to the internal chamber of each filter plate 2. Then, the hydraulic cylinder 6 drives the extrusion plate 7 to extrude each filter plate 2. The water in the sludge is discharged through the outlet pipe 22 and flows into the water storage tank 4 for collection. The dewatered sludge forms a filter cake in the filter plate 2. After the filter press is completed, the hydraulic cylinder 6 drives the extrusion plate 7 to reset. The control component 9 controls the automatic plate pulling mechanism 8 to run. The electric guide block 82 drives the plate puller 83 to move along the electric guide rail 81. The plate puller 83 grabs and pulls open each filter plate 2 in sequence, so that the sludge filter cake in the filter plate 2 falls into the sludge tank 3 for collection, thereby completing the intelligent filtration treatment of sludge.
