vacuum belt filter press

Vacuum belt filter press is an efficient solid-liquid separation equipment, which realizes solid-liquid separation with vacuum negative pressure as the driving force. Its filtration section is set along the horizontal length direction, which can continuously and automatically complete a series of process operations such as filtration, cake washing, slag unloading and filter cloth regeneration, etc. The equipment uses filter cloth as the filtration medium. The equipment takes filter cloth as the filter medium, the ring-shaped tape is driven by the motor through the deceleration device to run continuously, and the filter cloth is spread out on the account of the soldiers and its synchronized movement. When the tape and the vacuum system connected to the vacuum chamber sliding contact, the tape will form a vacuum filtration area, at this time the slurry through the fabric evenly spread on the filter cloth, the filtrate through the filter cloth, through the account of the cross groove on the summary of the groove, in the small holes into the vacuum chamber, and solid particles are retained to form a filter cake.

Product Advantages

High efficiency filtration

Adopting horizontal filter media surface feeding method, the large particles in the slurry can be quickly settled, and precipitated on the surface of the filter media in a very short time, to build up a primary filter media layer with high permeability, and the initial filtration effect is very outstanding.

High production capacity

It can continuously cut a series of process operations such as automatic bending and sinking filtration, filter cake washing, slag discharge and filter cloth regeneration, which greatly improves the production efficiency.

Good washing effect

The mother liquor and the washing liquor of the filter cake can realize segmented cell phone, supporting multi-stage flat flow or counter-flow washing mode, ensuring the washing process is even and thorough.

Low water content of the filter cake

With strong filtration performance, the resulting filter cake has low water content, which is very suitable for the subsequent processing requirements.

Flexible operation

The overall structure utilizes the modular design concept, which can be flexibly assembled according to the actual needs, greatly facilitating transportation and installation.

Low cost

High degree of automation, effectively reducing the manual operation, which in turn reduces the operating cost of the equipment.

Technical features:

· High degree of automation: continuous automation of the whole process of feeding, filtration, washing, sucking, unloading and filter cloth cleaning, and PLC program or DCS technology can be used to realize on-site or remote automatic control.

· Flexible process adjustment: parameters such as cake thickness, water absorption, number of countercurrent stages, vacuum degree, filter cloth, etc. can be adjusted according to demand, so as to achieve the best filtration effect.

· Deskewing device: the cylinder or airbag is used to push the deskewing mechanism to rotate and correct the deskewing, which automatically corrects the deviation of the filter cloth and ensures the normal operation.

· Tensioning device: Adjusting the tape tensioning progress with a screw to ensure sufficient friction and no deviation of the tape.

· High-efficiency cleaning: process water jet cleaning filter cloth and tape, with vacuum suction pipe sealing box, spray nozzle using high-quality products to ensure the cleaning effect.

The structure of a vacuum belt filter press

The components of a vacuum belt filter for gypsum are relatively intricate and can be divided into core functional components and auxiliary supporting components.

Core filtration and dewatering components

Filter belt: As the key filtration medium, the filter belt is responsible for carrying the material and completing the filtration and dewatering tasks. It is typically made of high-strength, wear-resistant woven materials, such as polyester or polypropylene.

Vacuum Chamber: Located below the filter belt, it uses negative pressure to adsorb materials from the filter belt's surface, serving as the key component for vacuum dewatering. It closely adheres to the filter belt to ensure effective vacuum performance.

Feed System: Includes a feed hopper and distributor, used to uniformly distribute the slurry across the belt, ensuring optimal utilization of the filtration area.

Dewatering section components: Divided into gravity dewatering zone, vacuum pre-dewatering zone, vacuum pressing dewatering zone, etc., based on the dewatering process. Different combinations of pressure and vacuum levels in each zone enhance dewatering efficiency.

Filter belt operation control components

Drive system: Comprising a motor, reducer, drive rollers, etc., it drives the filter belt to run continuously and can adjust the belt speed through speed control.

Tensioning device: Adjusts the filter belt tension via cylinders or lead screws to ensure the belt is tightly fitted to the pre-vacuum box, while preventing the belt from being too loose or too tight.

Alignment device: Includes sensors and pneumatic/electric adjustment mechanisms to monitor the filter belt position in real-time and make adjustments, preventing belt misalignment that could cause equipment malfunctions.

Auxiliary pre-installation components

Vacuum system: Comprised of a vacuum pump, vacuum piping, and a gas-liquid separator, it provides a stable vacuum source for the equipment.

Rinsing device: Includes spray pipes and nozzles, used to clean residual filter cake from the filter belt surface, preventing blockages and ensuring its permeability.

Discharge device: Typically a scraper or roller structure, it removes and discharges the dewatered filter cake from the filter belt.

Frame: A steel structure frame supporting all components, ensuring the overall stability of the equipment.

Control System: Comprised of a PLC, touchscreen, sensors, etc., enabling automatic adjustment of parameters such as filter belt speed, vacuum level, and rinsing pressure, as well as monitoring of equipment operation.

These components work together to complete the entire process of material feeding, filtration, dewatering, unloading, and filter belt regeneration, ensuring stable and efficient operation of the equipment.

Application areas

Vacuum belt filter for gypsum with excellent performance and various advantages, known as an indispensable key equipment for solid-liquid separation in many industrial fields, showing an extremely wide range of application prospects.
