High-efficiency dense-medium shallow-tank separator

Abstract

The invention provides a high-efficiency dense-medium shallow-tank separator, which comprises a tank body with an ascending medium flow chamber, a material inlet, a horizontal medium flow inlet, a horizontal medium flow water distribution jacket, an overflow port, an ascending medium flow inlet, an ascending medium flow water distribution jacket, a sewage discharge outlet, a scraper chain transmission mechanism, an ascending medium flow distribution plate (namely a pore plate), and a gangue outlet. The high-efficiency dense-medium shallow-tank separator is characterized in that the tank body and the ascending medium flow chamber are designed into a whole, and are divided into an upper chamber and a lower chamber by the ascending medium flow distribution plate, namely the pore plate, the upper chamber is a separating tank body, and the lower chamber is a medium flow chamber; and the ascending medium flow distribution plate is provided with the sewage discharge outlet at the lowest point of the lower part of the tank body. The high-efficiency dense-medium shallow-tank separator simplifies the machining process, saves materials, increases the reliability, can furthest provide ascending medium flow, ensure the effective separation space of a fluidized-bed dense-medium shallow-tank separator to form a steady and continuous fluidized bed, and realize high-quality separation.

Description

technical field [0001] The invention relates to lump coal washing equipment, in particular to a fluidized bed dense medium shallow groove separator. Background technique [0002] Dense medium shallow tank separator has become an important lump coal washing equipment for dense medium coal preparation because of its high efficiency, good separation effect and strong adaptability. Ideal equipment for jigging coal separator. The existing dense medium shallow tank sorting machine is composed of a tank body, a feeding trough, an overflow weir, a gangue discharge port, a horizontal medium inflow inlet, an ascending medium inflow bucket (number 2 to 6), and a scraper chain movement mechanism. The structure has the following disadvantages: 1. The excessively long rising medium inflow bucket increases the overall height of the equipment, takes up too much process space, and increases the manufacturing cost of the bucket itself and the difficulty of sealing the connecting flange. 2. ...

Problems solved by technology

The existing dense medium shallow tank sorting machine is composed of a tank body, a feeding trough, an overflow weir, a gangue discharge port, a horizontal medium inflow inlet, an ascending medium inflow bucket (number 2 to 6), and a scraper chain movement mechanism. The structure has the following disadvantages: 1. The excessively long rising medium inflow bucket increases the overall height of the equipment, takes up too much process space, and increases the manufacturing cost of the bucket itself and the difficulty of sealing the connecting flange

2. Due to the adoption of the structure of the ascending medium inflow bucket, there must be enough loading and unloading space between adjacent ascending medium flow entering buckets, because the ascending medium flow distribution plate (orifice plate) can only be installed on the upper part of the ascending medium inflow bucket , so that there is a large distance between adjacent ascending medium flow distribution plates (orifice plates), so that the ascending medium flow can only be distributed in several intermittent groups, and continuous and evenly distributed ascending medium flow cannot be formed in the effective space of the tank body. group, but only about 1 / 3 of the effective space, seriously affecting the sorting quality and output
