As a solid-liquid separation equipment integrating vacuum negative pressure adsorption and continuous conveying technology of annular conveyor belt, Horizontal belt filter upgrades the traditional filtration operation into a stable and efficient continuous production mode through the design of automated process. With accurate parameter control, reliable separation performance and intelligent operation cross-section, this equipment has become the core equipment for solid-liquid separation process optimization in the fields of environmental protection, chemical industry, metallurgy, food and so on.

Core Advantages
The unique performance of the Horizontal belt filter stems from its innovative structural design and dynamic filtration mechanism, which is mainly reflected in the following technical characteristics:
Full process operation
Relying on the closed-loop circulatory system of the ring-shaped crawler belt, it realizes the uninterrupted continuous operation of fabric, filtration, washing, dewatering and unloading, which perfectly matches the demand of industrialized large-scale production.
Intelligent parameter control
Integrated PLC automatic control system can adjust the key parameters such as the running speed of filter belt, vacuum adsorption strength, feed flow rate, etc., to ensure the process stability and reduce the dependence on manpower.
Accurate filter cake control
Through dynamic balance of the filter belt moving rate and vacuum negative pressure value, can be customized to control the range of filter cake thickness and final water content.

Working Principle
Four steps to complete high-efficiency continuous filtration
Horizontal vacuum belt filter with “continuous operation” and “vacuum suction” as the core design concept, its complete workflow can be divided into the following four key links:
Uniform fabric stage
The slurry is evenly spread on the surface of the circulating moving filter belt through the special feeding system, and the filter belt enters the vacuum adsorption area smoothly with the transmission device.
Vacuum solid-liquid separation stage
Driven by the negative pressure generated by the vacuum box, the liquid phase in the slurry quickly passes through the filtering cloth to enter the liquid collection cavity, and the solid phase particles are retained and compacted to form a dense filter cake.
Depth purification and dewatering stage
When the purity of the filter cake is needed to be improved When it is necessary to improve the purity of the filter cake, the washing system sprays the cleaning liquid, realizes the impurity replacement under the action of vacuum, and then the filter cake enters into the high-pressure dewatering area, and further reduces the moisture content through mechanical extrusion.
Automatic unloading and filter belt regeneration stage
When the filter belt carrying the filter cake runs to the unloading roller, it realizes solid-phase stripping through the scraper or blowback device, and then the filter belt goes through the washing and spraying system to remove the residual particles, and then re-enters to complete the closed-loop cycle.
