Description

Air room type jigger under small sieve

The utility model relates to gravity separation machinery technical field.

Jigging machine has been widely used in coal preparation plant and ore dressing plant at present and has handled coal or ore, and it utilizes the mine particle group of different densities to come coal separation or ore by the principle of density stratification in the variable velocity media stream of vertical lift.Existing sieve air cell type jigging machine down is that pneumatically alternately enters and discharges air chamber and forms fluctuating flow and evenly pass washbox screenplate under sieve, make the material that is positioned on the sieve plate alternately rise or descend, material all is subjected to certain sorting under the pulsation each time of current, through repeatedly repetition, layering is perfect gradually.Under the effect of horizontal flow, selected material is moved to exhaust end by material feeding end, at exhaust end, the light product that is positioned at the upper strata enters on second section sieve plate of jigging machine through overfall with water, heavy product is discharged into underpart and discharges body with the heavy product of saturating sieve by the bottom through discharge device, emit with conveying arrangement and elevator again,, also be provided with the complicated electric pole type water level visual indicator of structure in order to indicate each sieve the water level height and the range of movement of air chamber down.The air cell type jigging machine is main equipment under this sieve of producing at present, can not adapt to the numerous small-sized coal preparation plant of China and the needs in ore dressing plant; Jigging machine and bucket elevator manufacture and design respectively and are separate equipment, connect with chute therebetween, and not only Installation and Debugging complexity, and also floor space is big; The discharge device of jigging machine is made up of testing agency, control system and executing agency, and structure is very complicated, maintenance difficult, and in addition, electric pole type water level visual indicator seldom uses in practical work process, performs practically no function.

The purpose of this utility model provides that the air cell type jigging machine satisfies the needs in small-sized coal preparation plant and ore dressing plant under the improved small-sized sieve, and elevator and jigging machine be combined as a whole, simplify discharge device and omit electric pole type water level visual indicator, reduce production costs greatly so that reduce maintenance capacity.

Air cell type jigging machine under the small-sized sieve described in the utility model, its body is divided into air chamber under top jigging chamber and the sieve by sieve plate, the top of body is bellows chamber and Shui Bao, bellows chamber is connected with air-valve and is communicated with air chamber with pipe fitting, the water bag is connected with body with gate valve with pipe fitting, be characterized in being connected with the bucket type lifting device at the tail end of body, the discharging opening of bucket type lifting device is on top, and the discharge gate of jigging chamber is controlled by manual gate.

Adopt the advantage of air cell type jigging machine under the small-sized sieve described in the utility model to be: it is the small-sized jigging machine that aims at small-sized coal preparation plant and ore dressing plant development for (1), has compact conformation, and easy and simple to handle, maintenance capacity is little, and volume is little, takes up an area of to lack advantage of high precision; (2) it is particularly suitable for the use of small-sized coal preparation plant, and one two sections this jigging machine is that the 26S Proteasome Structure and Function that will have jigging machine, spoil elevator and middle coal elevator now becomes one, and it can produce cleaned coal simultaneously, three kinds of products of middle coal and spoil; (3) because jigging machine and bucket elevator are combined as a whole the parts that simplify the structure, and Installation and Debugging are very convenient.Automatically controlled discharge device is reduced to manual valve and has omitted electric pole type water level visual indicator, greatly reduce production cost.

Illustrated embodiment is described in further detail air cell type jigging machine under the small-sized sieve described in the utility model with reference to the accompanying drawings.
