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 high density metal minerals, rapid sedimentation, and strong impact force on the filter pipes from the filtrate containing solid particles, it has made a leap in optimizing and improving overall stability and structural reliability. It features solid structure, smooth disk operation, powerful automatic variable speed mixing, reliable shaft-end sealing, abrasion-resistant and durable ceramic filter tubes, high filter fan strength, and large porosity. The filter cloth also boasts high tensile strength, smooth surface, high cake discharge rate, and long service life, ensuring excellent dewatering performance during solid-liquid separation.
One: Filter Fan
To overcome certain deficiencies in the use of 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 uniformly distributed dehydration holes and a reasonable hole rate. Both the edges of the filter vanes and ribs are rounded, which not only improves the dehydration rate but also extends the service life of the filter cloth.
2. The filter fan head features chamfered edges for high strength, and the bottom is reinforced with ribs for added durability, making it less prone to damage or breakage during assembly and disassembly.
3. The rib orientation forms a reasonable angle with the centerline of the filter blade, resulting in low fluid resistance. The larger 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 sturdy 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 unique stainless steel bolts, significantly enhance both the corrosion resistance and ease of disassembly of the filter blades.
Section 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, which are less prone to wear and can extend the lifespan by two to three times.
2. The flange connection at the liquid filter tube and filter fan interface has been eliminated, and instead, direct welding is used with mold positioning. This removes the factor of aging gasket pads in the original flange connection, thus eliminating potential gas leakage points.
Each filter blade is secured with a pressure plate, with stainless steel bolts and nuts tightly fastened at both ends, making it resistant to rust and easy for later filter cloth replacement, significantly reducing labor intensity.
III. Mixing
In response to the special properties of mineral powder and the common issues of filter machines leaking and mixing systems being unreliable in today's market, our company has adopted the following mixing device to achieve optimal results, and has received widespread positive feedback from customers.
1. Utilize port magnetization anti-seepage technology or spiral sealing – 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 resistance to rust.
Four: Tank Chassis
The tank, serving as a container for the material slurry and a load-bearing support for equipment, plays a crucial role in product stability due to its sturdy and durable structure. Additionally, the addition of an alumina polymer wear-resistant coating at the bottom of the tank fundamentally resolves the issue of easy wear and tear.
2. For different materials, we select different materials to manufacture the tanks. Available options include carbon steel, stainless steel, carbon steel lined with rubber plates, and anti-corrosion lined tanks.
5. Control Panel, Friction Discs:
Customized wear-resistant boron phosphide cast iron, lubricated with yellow grease, offers a balance of hardness and flexibility, excellent sealing performance, and a lifespan of over three years.
Six: Lubrication and Cleaning
Utilize centralized multi-point automatic lubrication with oil pumps to ensure smooth operation of the equipment.
The filter cloth is cleaned using an automatic cleaning device, ensuring continuous cleaning while in operation, thereby maintaining excellent dewatering efficiency.
Section 7: Electrical Control
Utilizing variable-frequency speed regulation, the system adjusts based on the concentration and flow rate of the material to achieve optimal operating results.
