PGT (ZPG, GPT) Drum Vacuum Filter
The mining heavy-duty disc vacuum filter draws upon the advantages of similar foreign products, and optimizes its overall stability and structural reliability with a leap in improvement. It features robust structure, smooth filter disc operation, powerful automatic speed variation of the stirrer, reliable shaft-end sealing, abrasion-resistant and durable ceramic filter tubes, high filter fan strength, and large porosity. The filter cloth boasts high tensile strength, a smooth surface, high cake discharge rate, and a long service life, ensuring excellent dewatering performance during solid-liquid separation.
Technical Features
One: Filter Fan
To overcome some defects in the existing filter fans, our company has conducted numerous reliability tests specifically tailored to the unique requirements of the mineral processing industry, finally developing a new type of filter fan that meets market demand.
The surface is smooth with evenly distributed dehydration holes, reasonable porosity, and rounded edges on the filter vanes and ribs. This not only enhances the dehydration rate but also prolongs the service life of the filter fabric.
2. Filter fan heads feature chamfered edges for high strength, and the bottom is reinforced with ribs, making them 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 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 special stainless steel bolts, significantly enhance both corrosion resistance and ease of disassembly for the filter blades.
2. Main shaft and filter tube:
1. The filter tubes (including the shaft end) are made of high-strength wear-resistant ceramic composite steel pipes, with thick walls that are not prone to wear, significantly extending the lifespan by two to three times.
2. The connection between the filtrate tube and the filter fan has eliminated the flange joint and instead uses mold positioning for direct welding. This removes the factor of aging gasket pads in the original flange connection, eliminating potential gas leakage points.
Each filter blade is secured with a pressure plate, with stainless steel bolts and nuts at both ends for tightness, rust-resistant, and easy filter cloth replacement, significantly reducing labor intensity.
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 ideal results, which has received widespread positive feedback from customers.
1. Utilize port magnetization anti-leakage technology or spiral seal – 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, 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 robust and durable structure. By adding an alumina high molecular wear-resistant coating at the bottom of the tank, the issue of easy wear on the tank is fundamentally resolved.
2. Different materials are used for the槽body, depending on the type. Options include carbon steel, stainless steel, carbon steel lined with rubber plates, and corrosion-resistant lining, among others.
Five: Control Disk, Friction Plate
Utilizing specially formulated wear-resistant boron-phosphorus cast iron, lubricated with yellow grease, offering a balance of rigidity and flexibility, excellent sealing performance, and a lifespan of over three years.
Six: Lubrication and Cleaning:
Utilize centralized multi-point automatic lubrication with a dry oil pump to ensure the normal operation of the equipment.
The filter cloth is cleaned using an automatic cleaning device, ensuring continuous operation while cleaning, thus maintaining excellent dewatering efficiency.
Section 7: Electrical Control
Utilizing variable frequency speed control, it adjusts according to the concentration and flow rate of the material, achieving ideal working performance.
