Problems solved by technology

However, there are many deficiencies in the current dry coal preparation technology of vibrating fluidized bed. The transmission structure is relatively complicated, which leads to the vibration energy destroying the bed transmission structure and affecting the stability of the equipment structure; the vibration source needs to drive the entire bed to move. Power consumption is large, and most of the vibration energy is used for non-effective content

Abstract

A fluid-bed separator comprising a vibrating air distribution plate can be used for dry separation of coal, ore and other materials. The fluid-bed separator comprises a fluid-bed housing, a pressure stabilizing air distribution chamber, a feeding bucket, a discharge device, a dedusting seal cover, a vibrating air distribution device and a base. The dedusting seal cover is connected with the upper part of the fluid-bed housing; a fixing frame, the vibrating air distribution plate, a vibration exciter, a gas predistribution chamber, a gas predistributor and the base are connected with the lower part of the fluid-bed housing; vibration energy is transferred to a fluid bed through the vibrating air distribution plate to prevent bubbles from being generated in a fluid bed layer and form a uniform and stable fluidization state; materials in the fluid bed are layered according to the Archimedes principle; feeding is conducted above the front end of the fluid-bed housing; light products are discharged from above the tail end of the fluid-bed housing; heavy products are discharged from below the tail end of the fluid-bed housing, thereby realizing layering and separation of the materials according to different densities finally; and the separator reduces the effects of the bubbles in the fluid bed, the damage and loss of equipment structures caused by vibration, and unit energy consumption for material separation, and is efficient, energy-saving and environmentally friendly.

Description

technical field [0001] The invention relates to a dry separation equipment, in particular to an air distribution plate vibrating fluidized bed separation machine suitable for separation of coal and other minerals, which belongs to the technical field of mineral processing machinery. Background technique [0002] In the separation and processing of coal and other minerals in arid, water-deficient, severe cold and freezing regions, the traditional wet separation method is difficult to carry out, and the air-dense medium fluidized bed dry coal preparation technology can better meet this special separation. select requirements. At present, the dry separation equipment mainly includes compound dry separation machine, air jigging separation machine and air heavy medium fluidized bed dry separation machine. Among them, the air-dense medium fluidized bed dry separation machine has a better separation effect, but the fluidized bed dry coal preparation technology generally has a thic...
