GPY Series Disc Filter Ore Dressing Equipment Paddle-Type Agitator
1. Purpose
GPY series disc filter is mainly used for the dehydration of fine-grained materials such as 0~0.5mm flotation clean coal and tail coal, and can also be used for solid-liquid separation in metallurgy, chemical industry, petroleum and sewage treatment.
2. Working principle
The filtration process of the disc filter is: under the action of the pressure difference formed by the vacuum pump, a particle filter cake is formed on the filter cloth, and the liquid phase is removed through the filter cake and the filter cloth to achieve solid-liquid separation, and the filter cake enters the drying area. Most of the water is removed, and then it enters the blow-off area. The compressed air generated by the blower blows off part of the filter cake on the filter disc, and the rest of the filter cake is discharged by the scraper, which is completed in one cycle.

4. Main Features
(1) The transmission device has a compact structure, reliable operation and stepless speed regulation;
(2) Equipped with a torque-limiting coupling, which plays the role of overload protection and ensures the safe and reliable operation of the main engine;
(3) The central shaft is a welded structure, which is light in weight, good in rigidity, high in strength and large in filtrate displacement. The bushing is SP composite material, which is light in weight and wear-resistant;
(4) The new star point type plastic fan-shaped plate is adopted, which is light in weight, high in strength, good in hydrophobicity, high in opening rate, good in dehydration and de-cake effect, low in filter cake moisture, long in service life, corrosion-resistant and convenient for decoration;
(5) The filter cloth is woven with stainless steel wire, which has good filtering effect, low filter cake moisture, high cake removal rate and long service life;
(6) The paddle-type agitator floating-type sealing stuffing box is adopted, allowing the agitator shaft to float to a certain extent, the sealing effect is good, and the sealing parts are easy to replace;
(7) Combined use of instantaneous air blowing and suspended scraper unloading device not only has a high unloading rate (up to 90%), but also the scraper can swing with the filter disc, and the filter disc is in a good state of force, reducing the load on the host;
(8) In addition to the above advantages, the new GPY20-120 series products are designed according to the size of the foundation and the discharge port, which is convenient for the renovation of the old factory and the renewal of the equipment.
