Golden Machinery Provides High Quality Thickener Tank /Agitator to Our Customers.The Thickener Tank is a continuous working concentration and clarification equipment. It is mainly used for the dewatering of fine and tailing pulp in wet beneficiation operations. It is also widely used for the concentration of solid slurry in coal, steel, chemicals, building materials, water sources, and sewage treatment. And purification. Ordinary concentrators work reliably, have low operating costs, and can act as storage and buffering for feeds. However, it is based on the principle of particle gravitational sedimentation. The sedimentation velocity is proportional to the square of the particle diameter, and it is used to treat the fine-grained material family with low efficiency. High-efficiency thickeners mainly use the rational use of flocculants and the use of materials at the bottom to increase the settling velocity. This is one of the most important advances in concentration technology.
The surrounding transmission rake type thickener is mainly composed of a truss, a trough frame, a center support, a current collection device, a transmission device, etc. Its transmission device transmits the motion and power of the motor to a truss on which the target is hung so that the truss is in the pool. Rotate evenly around the center and target the concentrated product to the discharge outlet in the center of the bottom of the pool. The clarified overflow water overflows around the pool and is discharged through the annular overflow tank.
The operating principle of the peripheral transmission type concentrator is that an annular contact is provided on the center post, and the collector contact sliding along the ring is connected with the truss, and the current is introduced into the motor to supply power to the motor. Peripheral transmission The entire transmission system is relatively simple, reliable operation, low cost, but the surrounding drive should have enough friction, for large diameter thickeners, if the steel drive wheel is used to drive on the rails, its friction is not enough, and it is prone to slippage. . Ordinary concentrators add racks to the inner side of the rails and use racks and racks to transmit torque. However, from the perspective of on-site use, due to the low precision of the manufacturing and installation of racks and gears, the occurrence of pinching is likely to occur. Therefore, maintenance costs are high. Another type of multi-rub wheel drive is to directly contact the rubber wheel with the concrete surface, increasing the contact surface friction, saving the rail track and rack, and reducing the failure rate and saving maintenance costs, even for a long time Do not replace the rubber wheel, the effect is still better. For example, the well-known Yantai Xinhai Mining Machinery's peripheral transmission thickener is manufactured using this principle. It has a high safety factor, low energy consumption, good concentration effect, and is widely used.
The driving power of the peripheral transmission concentrator is the gear driven by the motor reducer on the peripheral arm, through which the gear meshes with the circular rack on the pool side, and then the arm moves the truss, and the truss is in certain position. The angle scraper scrapes the high concentration sludge from the bottom of the tank to the center and drains away. In order to prevent gear wear, the support arm has a track slightly smaller in radius than the circular rack. The power required by the rotating motor is transmitted through the center slip ring of the pool and serves as a support.

Golden Machinery also offers many good mixing equipment because he is also an excellent Mixing Tank Suppliers.
