PGT (ZPG, GPT) Disc Vacuum Filter
The mining heavy-duty disk vacuum filter has fully absorbed the advantages of similar foreign products. Addressing the characteristics of metal minerals with high density, rapid sedimentation, and strong impact force on the filter tubes from solid-containing filtrates, it has achieved a leap in optimization and improvement of overall stability and structural reliability. It features robust structure, smooth disk operation, strong automatic speed variation of agitation, 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, ensuring excellent dewatering indicators in solid-liquid separation.
Technical Features
One: Filter Fan
To overcome certain defects in the current use of filter fans, our company has conducted numerous reliability tests tailored to the specific needs 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 and a reasonable hole rate. Both the edges of the filter vanes and ribs are rounded, which not only enhances the dehydration rate but also prolongs the service life of the filter fabric.
2. The filter fan head features chamfered edges for high strength, and the bottom has reinforced ribs for durability, making it less prone to damage or breakage during assembly and disassembly.
3. The rib direction forms a reasonable angle with the centerline of the filter blade, resulting in low fluid resistance. The large effective area of the filter blade enhances 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 fans, paired with stainless steel bolts, significantly enhance both corrosion resistance and ease of disassembly.
Section 2: Main shaft and filter tube:
1. Filtration tubes (including shaft ends) are made of high-strength, wear-resistant ceramic composite steel pipes with thick walls, which are not prone to wear and significantly extend lifespan by two to three times.
2. The flange connection at the interface of the filtrate tube and filter fan has been eliminated, and direct welding is now achieved through mold positioning. This eliminates the factor of aging gasket pads in the original flange connection, thereby removing potential air leak points.
Each filter blade is secured with a pressure plate, with stainless steel bolts and nuts tightly fastened at both ends, which is rust-resistant and facilitates the later replacement of the filter fabric, significantly reducing labor intensity.
3. Mixing:
In response to the special properties of mineral powder, and considering the current market issues with filters prone to leakage and mixing systems that are not durable, our company has adopted the following mixing device to achieve optimal results and has received widespread positive feedback from customers.
1. Utilizing port magnetization anti-seepage technology or helical sealing – to prevent mineral powder from entering the mixing sleeve.
2. Utilizes water-tight seal.
3. Utilizes a PTFE composite seal.
4. Filling and Sealing.
5. The shaft surface is chrome-plated, making it resistant to rust.
Four: Tank Chassis
1. 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 sturdy and durable structure. Adding an alumina high molecular wear-resistant coating at the bottom of the tank fundamentally addresses the issue of its susceptibility to wear.
2. For different materials, we select different materials to manufacture the troughs. Available options include carbon steel, stainless steel, carbon steel lined with rubber plates, and corrosion-resistant linings, among others.
Five: Control Panel, Friction Plate
Customized abrasion-resistant boron phosphide cast iron with yellow grease lubrication, combining toughness and flexibility, excellent sealing performance, lifespan over three years.
Six: Lubrication and Cleaning:
Utilize centralized multi-point automatic lubrication with dry oil pumps to ensure the normal operation of the equipment.
The filter cloth is cleaned using an automatic cleaning device, ensuring continuous operation and cleaning, thus maintaining excellent dehydration effects.
Section 7: Electrical Control
Utilizing variable-frequency speed regulation, the system adjusts based on the material's concentration and flow rate to achieve optimal operating results.
