Fully Automatic Integrated Sludge Dewatering Hydraulic Tower Filter Press

The HVPF vertical automatic filter press represents the pinnacle of filtration technology. While vacuum-based filtration has inherent limitations, pressure-driven separation offers far greater potential. The HVPF system utilizes highly pressurized air or water to generate an extreme pressure differential across the filter cloth, enabling exceptionally efficient solid-liquid separation.

Here's how it works: once the filter plates are securely closed, slurry is pumped into the filtration chambers. An initial amount of filtrate drains by gravity through the cloth into the collection system. Next, high-pressure water is introduced to expand rubber diaphragms, which mechanically compress the filter cake and express residual liquid. Upon completion of the cycle, the drive mechanism activates to move the filter cloth, discharging the solid cake from both sides of the press automatically.

Product Application:

The HVPF vertical automatic filter press is a high-capacity, energy-efficient solution for solid-liquid separation, suitable for a wide range of industries including mining, metallurgy, chemicals, pharmaceuticals, and food processing.

 Working Process:

The filtration process consists of the following five stages:

1.  Filtration Stage
   Once the filter plates are closed, slurry is pumped into the chambers via the feed pipe. The filtrate passes through the filter cloth, enters the collection chamber, and is discharged through the manifold. Simultaneously, solid material accumulates within the chambers, forming the filter cake.

2. Membrane Squeeze Stage
   High-pressure water is introduced into the membrane plates, causing the membranes to expand and apply uniform mechanical pressure to the filter cake. This action significantly reduces the cake moisture by expressing additional filtrate.

3.  Cake Washing (Optional)
   Washing liquid is pumped through the same feed distribution system to permeate the filter cake. The spent wash liquor passes through the cloth and is discharged separately via the designated outlets.

4. Air Blow-Drying
   Compressed air is introduced to pass through the cake, displacing residual moisture and further reducing the cake's liquid content. This step also helps clear any remaining filtrate from the discharge system.

5. Cake Discharge
   Upon completion of the cycle, the drive mechanism moves the filter cloth, causing the solid filter cake to be cleanly and automatically discharged from both sides of the filter.

1. The structure of filter plate adopts guide device to make sure the smoothly running.        

2. It can continuously automatically realize the operation in the process of filtering, extrusion, washing, drying, discharging and filter cloth regeneration.         

3.  The filter pressure can reach 2.0 Mpa. Especially have good effect on various sticky tiny materials and low moisture of filter cake.        

4. the key point of this type of equipment is no matter how much pressure it can get but safety. Hydraulic pressure system is adopted just to make sure every plate locks well. Every nozzle and diaphragm are designed and inspected very carefully to keep the equipment safe when high pressure water gets into chambers.        

5. The equipment adopts PLC + touch screen + automatic valves, and labor input is lower..        

6.  Compact structure covers less floor area
