PGT (ZPG, GPT) Disc Vacuum Filter
The mining heavy-duty disk vacuum filter has fully absorbed the advantages of similar foreign products. It addresses the characteristics of metal minerals with high density, rapid sedimentation, and strong impact force on the filter tubes due to the filtrate containing solid particles. It has made a leap in optimizing the overall stability and structural reliability. It features robust structure, smooth filter disk operation, powerful automatic variable speed stirring, reliable shaft end sealing, abrasion-resistant and durable ceramic filter tubes, high filter fan strength, and large porosity. The filter cloth has high tensile strength, smooth surface, high cake discharge rate, and long service life. It ensures excellent dewatering indicators in solid-liquid separation.
One: Filter Fan
To overcome some shortcomings in the current use of filter fans, our company has conducted numerous reliability tests specifically tailored to the unique requirements of the mineral processing industry, ultimately developing a new type of filter fan that meets market demand.
The surface is smooth with evenly distributed dehydration holes, having a reasonable hole ratio. Both the edges of the filter vanes and ribs are rounded, which not only enhances the dehydration rate but also extends the lifespan of the filter fabric.
2. The filter fan head features chamfered edges for high strength, with reinforced ribs at the bottom. It is less prone to damage or breakage during assembly and disassembly.
3. The angle between the rib direction and the centerline of the filter blade is reasonable, resulting in low fluid resistance. The effective area of the filter blade is large, enhancing the processing capacity of the filter machine.
4. The wall thickness of the filter fan is increased by 1/3 compared to the standard, and so is its weight by 1/3. It is a structurally sound and robust filter fan available in the domestic market, with an average lifespan that can be extended by 1.5 to 2 times.
5. Special-structured filter blades, paired with stainless steel bolts, significantly enhance both corrosion resistance and ease of disassembly for the filter blades.
Section 2: Main shaft and filter tube:
Filter pipes (including shaft ends) are made of high-strength wear-resistant ceramic composite steel pipes, with thick walls that are not prone to wear, extending the lifespan by two to three times or more.
2. The flange connection at the interface of the filtrate tube and the filter fan has been eliminated, and direct welding with mold positioning is now used. This removes the factor of aging gasket pads in the original flange connection, eliminating potential gas leakage points.
3. Each filter blade is secured with a pressure plate, clamped at both ends with stainless steel bolts and nuts, which are resistant to rust and facilitate easy replacement of the filter cloth, significantly reducing labor intensity.
Section 3: Mixing
In response to the special properties of mineral powder and considering the common issues of filter machines leaking and mixing systems being unreliable in the current market, our company has adopted the following mixing device to achieve optimal results, and it has received widespread positive feedback from customers.
1. Utilize port magnetization anti-leakage technology or helical sealing – to prevent mineral powder from entering the mixing sleeve.
2. Utilizes water-tight sealing.
3. Utilizes PTFE composite sealing.
4. Filling and sealing with additional material.
5. The shaft surface is chrome plated for rust resistance.
Four: Tank Chassis
The tank, serving as a container for material slurry and a load-bearing support for equipment, plays a crucial role in product stability due to its robust and durable structure. By adding an alumina polymer wear-resistant coating to the bottom of the tank, the issue of easy wear on the tank is fundamentally addressed.
2. Different materials are used for the tank bodies according to the type of material. Available options include carbon steel, stainless steel, carbon steel lined with rubber plates, and anti-corrosion lined tanks.
Control Disk, Friction Plate:
Utilizing specially formulated wear-resistant boron-phosphorus cast iron, lubricated with yellow grease, offering a balance of flexibility and rigidity, excellent sealing performance, and a lifespan of over three years.
Section 6: Lubrication and Cleaning:
The equipment is equipped with a dry oil pump for centralized multi-point automatic lubrication, ensuring smooth operation.
The filter cloth cleaning utilizes an automatic cleaning device, achieving continuous cleaning while in operation, thereby maintaining excellent dewatering effects.
Section 7: Electrical Control
Utilizing variable frequency speed control, it adjusts according to the concentration and flow rate of the material to achieve ideal working performance.
