Working principle analysis
Horizontal screw centrifuge is a device that uses the strong centrifugal force generated by high-speed rotation to continuously separate solid-liquid mixtures. Its core structure includes a drum, a screw conveyor, a differential, a feeding system, a drive device and an automatic control system.
1. Basic separation process
The mixed liquid enters the high-speed rotating drum through the feeding pipe;
Under the action of centrifugal force, the solid particles with higher density are quickly deposited on the inner wall of the drum;
The screw conveyor rotating at a certain differential speed with the drum gradually pushes the deposited solids to the slag discharge port;
The clarified liquid is discharged from the overflow port at the other end of the drum to achieve continuous and stable solid-liquid separation.
2. Differential control
The differential adjusts the relative speed between the drum and the screw, which is a key factor in controlling the slag dryness and processing efficiency. Modern horizontal screw centrifuges mostly use variable frequency dual-motor drive systems to achieve precise differential control to meet the processing needs of different materials.
Product advantages
1. Efficient and continuous separation
The horizontal screw centrifuge can achieve all-weather uninterrupted operation, and is particularly suitable for processing suspensions with high solid content, fine particles and poor fluidity. Its separation factor can be as high as 3000G, far exceeding the traditional gravity sedimentation and belt filter press methods, and the separation efficiency is significantly improved.
2. Compact structure and flexible installation
The whole machine has a compact design structure, small footprint and high equipment integration. It can be customized according to different plant layouts, which is convenient for rapid deployment of new or renovated projects.
3. High degree of automation
Equipped with advanced PLC control system and human-machine interface (HMI), it supports automatic parameter adjustment, real-time monitoring of operating status, alarm protection and remote control, reducing manual intervention and operation risks.
4. A variety of refractory materials are available, with strong adaptability
The parts of the equipment that come into contact with the material can be selected from corrosion-resistant and wear-resistant materials such as 316L stainless steel, duplex steel, Hastelloy, titanium alloy, etc. according to customer needs, and can adapt to complex working conditions such as acid and alkali, high temperature and high wear.
5. Energy saving and environmental protection, low operating cost
The high-efficiency variable frequency motor, energy-saving drive system and intelligent unloading structure are used to effectively reduce the energy consumption and maintenance frequency of the equipment. The water content of the solid after separation is low, which is convenient for subsequent transportation and disposal, reducing the environmental burden.
Widely used in the fields of municipal and industrial wastewater treatment
Decanter centrifuges are widely used in sludge concentration and dehydration processes in urban sewage treatment plants, printing and dyeing plants, tanneries, electroplating plants, chemical parks and other fields. The equipment operates stably, and the water content of the treated sludge is low, which is convenient for subsequent drying or resource utilization.
2. Petroleum and energy industry
In the process of oil drilling, shale gas mining, and refinery wastewater treatment, decanter centrifuges are used for solid-liquid separation and recovery of oil sludge, water-based mud and oily wastewater, improving resource utilization and reducing waste treatment costs.
3. Food and beverage processing
In processes such as fruit and vegetable juice extraction, soy milk production, vegetable oil separation, soy sauce and vinegar filtration, decanter centrifuges can effectively remove dregs, improve the purity of finished products, ensure product quality, and meet food-grade hygiene requirements.
4. Biopharmaceuticals and Chinese medicine extraction
Chinese medicine extracts, antibiotic fermentation broth, vaccine production broth and other materials with high viscosity and high protein characteristics can be separated efficiently using a horizontal screw centrifuge to ensure the recovery rate of effective ingredients and product purity.
5. Chemical and new materials industry
It is widely used in process flows such as sediment removal, pigment classification, inorganic salt dehydration, and catalyst recovery to meet the continuous processing needs of high-precision and highly corrosive chemical materials.
