- High-efficiency dewatering technology
(1) High-pressure dewatering technology: some filter presses adopt higher pressure for filtration, which can make the water content of the filter cake lower. For example, the pressure of filter presses using hydraulic pressure can reach over 0.8-2.0MPa, which greatly improves the dewatering effect and is of great significance for sludge dewatering and other application scenarios requiring deep dewatering. For example, in municipal sludge treatment, the water content of sludge can be mechanically reduced from a high level directly to the water content that meets the standard of landfill and incineration, which reduces the difficulty and cost of subsequent treatment.
(2) Application of new filtration structure and principle: The working principle of stacked-screw sludge filter press is based on the relative movement between the screw shaft and the moving and fixed rings. Through the rotation of the screw shaft, the sludge is pushed forward by the screw shaft and passes through the gap between the moving and fixed rings, and is subjected to squeezing and shearing, so as to realize the dewatering of sludge. This structure enables the sludge to be squeezed and sheared in all directions during the dewatering process, which improves the dewatering efficiency.
- Intelligent technology:
(1) Automation control: The intelligent filter press system integrates advanced sensor technology, big data analysis, artificial intelligence algorithms and cloud computing and other cutting-edge technologies, realizing the automation control of the whole process from feeding, filtration, washing, unloading cake to cleaning. It reduces the burden of manual operation, improves filtration efficiency and stability, and ensures the consistency of product quality.
(2) Intelligent monitoring and adjustment: through the built-in high-precision sensors, the system can monitor the temperature, pressure, flow, viscosity and other key parameters of the material in real time, and according to the preset filtration process or real-time data feedback, it automatically adjusts the filtration pressure, speed, time and other control parameters to ensure that the filtration process is always in the optimal state. It can cope with complex working conditions such as high viscosity, easy to clog, corrosive materials and so on.
(3) Remote monitoring and troubleshooting: The intelligent filter press is equipped with an advanced intelligent management system, which realizes remote monitoring and troubleshooting of the equipment’s operating status. Users can check the operation data, fault alarm information and maintenance records of the equipment at anytime and anywhere, so as to find and solve problems in time and ensure the continuous and stable operation of the equipment. At the same time, the system can analyze the historical data to predict the maintenance cycle of the equipment and the demand for spare parts.
- Equipment structure and design innovation
(1) New type of cake unloading device: it solves the problems of splashing rinsing water and insufficient smoothness of the cleaning process during the cleaning of the filter plate, and it can speed up the efficiency of the filter plate rinsing and save time and labor.
(2) Multi-cylinder compression design: characterized by energy saving and high working efficiency. Multi-cylinder design can apply pressure more evenly, improve the filter press effect and reduce energy consumption at the same time.
(3) Double-head pressing design: some companies have developed filter presses with double-head pressing.
- Filter media innovation: new filter media continue to emerge, with stronger durability and anti-clogging ability, able to maintain efficient filtration effect in complex material filtration. For example, some of the use of special materials or structure of the filter cloth, filter plate, not only improves the filtration efficiency, but also extends the service life, reduces the cost of frequent replacement of filter media and waste.
- Energy saving and environmental protection technology:
(1) Optimization of filtration process: through the optimization of filtration process, the energy and water consumption of the equipment is reduced. For example, in some intelligent filter presses, unnecessary energy waste is avoided by precisely controlling the pressure, flow rate and other parameters in the filtration process.
(2) Waste liquid recycling and reuse: some filter presses have the function of waste liquid recycling and reuse, through appropriate treatment and recycling of waste liquid after filtration, it realizes the maximum utilization of resources and reduces the emission of waste water, waste residue and other pollutants, which is in line with the requirements of green production.
