Mobile combined coal preparation plant

Abstract

The invention provides a mobile combined coal preparation plant. Fives parts including coal preparation, coal slime collection, coal preparation waste water treatment and water recycling and utilization are installed in a first main machine box, a second main machine box, a third sewage treatment box, a fourth coal slime filter-pressing box and a fifth clear water box. Coal preparation equipment adopts a traditional coal preparation unit which is arranged in the first upper open machine box and the second lower open machine box, wherein the size of the first upper open machine box is consistent with that of the second lower open machine box, and the first main machine box is installed on the second main machine box and are fixed through an assembling piece. The lower ends of a middling coal outlet slot, a first gangue outlet slot and a second gangue outlet slot in the coal preparation unit are in butt joint with three U-shaped coal bunker inner cavities in the second main machine box in a matched manner correspondingly. The bottom of the third sewage treatment box is made into an overall concave-spherical-surface-shaped box bottom, the top of the third sewage treatment box is provided with an automatic travelling crane, the travelling crane is provided with a motor and an outward coal slime conveying pipe of a slime suction pump. One side of the box top is provided with a slope-shaped water tank with the bottom being made into a semicircular shape, and the slope-shaped water tank is connected with the coal slime conveying pipe. The capital construction expense is saved by about 60%, and the plant building period is shortened by about 65%.

Description

technical field [0001] The invention relates to a mobile combined coal preparation plant. Background technique [0002] Existing coal preparation machines are composed of coal preparation units, sorting screens and slime water pressure filter equipment, etc., because each part of the coal preparation equipment must form a relative height difference, so that all parts can work in harmony, especially The sorted coal and the sewage containing coal slime need to be sent to a suitable location for treatment. For example, the washed coal should be piled up in a coal bunker that is convenient for vehicle transportation and loading, and the sewage containing coal slime needs to be dehydrated. Generally, it is sent to the filter press equipment to filter out the water and leave the slime. The whole production process is a production line from high to low. Usually, the coal preparation unit is installed at a high position, and the generated sewage containing coal slime can be sent t...
