Technical Field

The invention relates to a high-efficiency thickener, in particular to an automatic high-efficiency thickener and a thickening method, belonging to the technical field of high-efficiency thickeners.

Background

The thickener is a continuously working concentrating and clarifying device, is mainly used for dewatering fine ore and tailing slurry in wet-type mineral separation operation, and is also widely used for concentrating and purifying solid-containing slurry such as coal, steel, chemical engineering, building materials, water sources, sewage treatment and the like. The common thickener has reliable operation and low operation cost, and can play a role in storing and buffering the feed. However, it is based on the principle of gravity settling of particles, and the settling velocity is proportional to the square of the particle diameter, so it is inefficient for processing fine particles. The high-efficiency thickener mainly adopts reasonable use of flocculant and adopts a material distribution mode of feeding materials from the bottom to improve the sedimentation speed, which is one of the most important progresses in the aspect of concentration technology.

The concentration mechanism of a common thickener is essentially gravity settling of the pulp. The method is based on the free sedimentation of ore particles, realizes the sedimentation and layering of the particles, namely the free sedimentation on the upper layer and the interference sedimentation on the lower layer of a thickening tank, and further compacts the particles in a compression zone at the bottom of the thickening tank, so that the treatment capacity of a thickener and the solids in a replenishing flow are lost, and the method is actually dependent on the sedimentation speed of the ore particles and mainly depends on the final speed of the free sedimentation.

The invention discloses a low-temperature high-speed rotating film concentrator, which comprises a material discharging hopper, a heating cylinder, a heat-insulating cylinder, a feeding cylinder, an external heating input pipe, an external heating connecting pipe, a heating ring, a rotating shaft sleeve, a motor, material dispersing blades, a blade seat, a baffle plate, an internal heating input pipe, an internal heating connecting pipe, a heating movable disk, a rotary joint, a feeding pipe, a discharging pipe, a vacuum pumping pipe, a heating input pipe and a heating output pipe.
