Core equipment for solid-liquid separation process innovation
As industrial development enters a new stage of high quality, green and intelligent development, separation technology in the production process is facing unprecedented challenges and opportunities. Traditional filtration equipment, sedimentation equipment, flotation devices, etc., when facing complex media such as high solid content, high viscosity, and multiphase mixed liquids, often have problems such as low processing efficiency, unstable operation, frequent manual intervention, and severe equipment wear. Horizontal screw centrifuge, as a continuous and automated high-speed centrifugal separation equipment, is becoming the “key engine” for innovative separation processes in many industries with its outstanding performance.
The biggest advantage of the horizontal screw centrifuge is that it can achieve efficient solid-liquid separation per unit time. It not only has high separation accuracy, but also has sustainable operation and intelligent control. It is widely used in municipal sewage treatment, industrial wastewater treatment, oilfield mud recovery, mine tailings dehydration, food and pharmaceutical processing, biological fermentation, dairy product clarification and other high-demand working conditions. The horizontal screw centrifuge made in China is rapidly emerging in the domestic and foreign markets with its advantages of high cost performance, strong customization capabilities and fast service response.
Detailed analysis of equipment structure
The horizontal screw centrifuge is mainly composed of a drum, a screw pusher, a differential, a frame, a drive system, an inlet and outlet, an electronic control system, etc. Its working principle is: the mixture enters the equipment from the feed pipe and is evenly distributed in the drum through the distribution port. As the drum rotates at high speed (generally between 2000 and 4000 RPM), the solids in the material are thrown to the inner wall of the drum due to their high specific gravity to form a sediment layer, while the liquid forms a clarification layer in the inner layer. The screw pusher slowly pushes the deposited solids to the outlet by differential rotation, forming a closed-loop process of continuous dehydration.
1. Drum system
The drum is the core component of the centrifuge. Its structural accuracy and material quality directly determine the operating stability and separation efficiency of the equipment. Our company uses CNC machine tools imported from Germany to manufacture the drum. The materials used are stainless steel 2205, 2507 or titanium alloy, etc., taking into account strength, corrosion resistance and wear resistance.
2. Screw conveyor
The blades are reinforced with carbide or tungsten carbide welding layer to effectively resist the erosion of highly abrasive media; by optimizing the pitch and cone angle design, the conveying efficiency is improved while reducing energy consumption.
3. Differential control
The planetary gear differential or hydraulic differential is used, with a large adjustment range and precise control, so that the dryness of the separated solids is optimized.
4. Drive mode
Currently, we provide dual-motor dual-frequency drive (main motor + auxiliary motor) or single-motor belt drive solutions, which can be flexibly configured according to the customer’s requirements for differential speed control accuracy and energy efficiency.
Typical industry applications and customer cases
1. Municipal sewage treatment plant
A large sewage plant originally used a spiral stacker to treat residual sludge with high moisture content and high viscosity, which had low operating efficiency. Later, it switched to our LW500 horizontal spiral centrifuge, which can treat 15 tons of sludge per hour, reduce the moisture content of the sludge by 15%, increase the daily processing capacity by 2 times, and operate stably. Customers highly praised the easy maintenance and labor saving.
2. Juice and beverage industry
A large juice processing plant provides LW355 food-grade horizontal spiral centrifuge, which completes solid-liquid separation and clarification without destroying the active ingredients of the juice, increases the juice yield by 10%, and saves nearly one million yuan in fruit raw material costs each year.
