Applications
Automatic Horizontal Scraper Filtration Centrifuge: industrial applications
Applications include alkalis, salts and fertilizers and polymers and inorganic chemicals. Confirm material properties and process conditions before selecting the equipment configuration.
Polymers and inorganic chemicals
PVC, calcium phosphate, sulfate products and other filterable chemical suspensions.
Food and starch processing
Starch and comparable food-process solids requiring filtration, washing and controlled dewatering.
Pharmaceutical production
Suitable pharmaceutical materials where automated operation, enclosed construction and project-specific GMP or explosion-protection measures are required.
Working Principle
From feed preparation to finished product.
The process route is selected around the material and product targets.
Controlled feeding
Charge the suspension into the horizontal rotating basket while the cake-layer controller regulates cake thickness and helps prevent overload or material carryover.
Filtration and washing
Centrifugal force drives the liquid through the filter medium. The retained cake can be washed according to the programmed process recipe.
Final dewatering
Continue high-speed rotation to reduce cake moisture before discharge.
Wide-knife scraping
A hydraulically actuated wide scraper with replaceable carbide blade removes the cake smoothly and efficiently.
Screw conveying and blowback
The screw discharge arrangement collects and conveys the solids, while blowback assists filter-medium regeneration before the next automatic cycle.
Performance Highlights
Process performance shaped around the product.
Final performance remains dependent on feed properties and engineering confirmation.
High-efficiency separation
High separation factors and short cycles provide high single-machine throughput and low residual cake moisture.
Full automatic cycle
PLC control sequences feeding, separation, washing, dewatering, discharge and blowback, with manual/automatic mode selection.
Controlled cake formation
Cake-layer measurement regulates cake thickness and helps prevent overload and material escape.
Secure enclosed construction
Hydraulic dual-locking, dovetail-flange sealing and explosion-protected enclosure options support demanding contained duties.
Smooth scraper discharge
Hydraulic wide-knife motion and a replaceable wear-resistant carbide blade deliver stable, efficient cake removal.
Effective vibration isolation
The floating-platform system and damped isolators minimize transmitted loads while supporting foundation-light installation.
High-strength transmission
Integral machining, coaxial bearing supports, stress relief and forced oil-spray lubrication provide rigidity, cooling and durability.
Continuous condition monitoring
Optional temperature, speed and vibration detection supports safer, more stable long-term production.
System Configuration
Standard process path with project-specific options.
Core equipment and auxiliary systems are selected around the process duty.
PLC and variable-frequency control
Automatic recipe sequencing, VFD speed control and selectable dynamic or regenerative braking support flexible manual and automatic operation.
Process monitoring
Cake-level, rotational-speed, bearing-temperature and vibration instruments provide real-time operating status and protective interlocks.
Hydraulic door locking
A fully hydraulic cover-locking system with dual locking protection and a dovetail-groove flange provides secure, reliable sealing.
Multiple shaft seals
Lip, gas and labyrinth seals improve isolation between the transmission and process zones; the spindle sleeve can be ion-plated for wear and corrosion resistance.
Stable scraper discharge
The welded high-rigidity scraper carrier, hydraulic actuation, replaceable carbide blade and screw conveyor support smooth cake removal with reduced plugging centrifuge.
Rigid lubricated drive
Coaxially machined front and rear bearing supports, stress-relieved welded construction and forced oil-spray lubrication improve alignment, cooling and service life.
Integrated vibration isolation
An integral floating platform, damped isolators and anti-slip mounting pads reduce transmitted dynamic loads and simplify foundation requirements.
Containment options
Fully enclosed, explosion-protected construction can be configured for GMP-oriented pharmaceutical production and flammable or explosive duties.
