A high-efficiency discharge stacked screen

Abstract

The invention relates to an efficient discharging lamination sieve which comprises a frame, a material divider, a distributing device, a lamination sieve body, a vibration exciter and a damper spring. The lamination sieve body is side plates arranged on the front side and the rear side of the frame, a plurality of sieving units are arranged between the side plates from top to bottom, combined discharging units are arranged sieving surfaces in any two sieving units, two discharging plates are symmetrically arranged forwards and backwards to form each combined discharging unit, a screen underflow discharging port corresponds to the discharging plates and is formed in the middle of two discharging plates when being inclined from two sides to the middle and the lower portion, screen underflow discharging ports correspond to the discharging plates and are formed among the two discharging plates and two side plates of the lamination sieve body when being inclined from the middle to two sides and the lower portion, and the screen underflow discharging ports corresponding to the combined discharging units are provided with screen underflow discharging channels corresponding to the screen underflow discharging ports. The efficient discharging lamination sieve is high in discharging efficiency and small in occupied space, and other discharging devices cannot be additionally added.

Description

technical field [0001] The invention relates to the technical field of powder screening equipment, in particular to a high-efficiency discharge stacked screen. Background technique [0002] Screening (or dehydration, de-intermediation) operations of materials are common in metallurgical mines, building materials, chemicals, coal, petroleum and other fields. With the expansion of production scale, the screening area of ​​the equipment required for material screening (or dehydration, de-intermediation) also increases, while the screen machines of the same size screen produced at home and abroad are all single-layer screens (except Derui Overlapping high-frequency fine sieve), the structural characteristics of single-layer sieve determine that it cannot perfectly meet the requirements of existing production development and material screening (or dehydration, de-intermediation) equipment requirements. [0003] This is because with the increase of the screening area of ​​the sin...

AI Technical Summary

Problems solved by technology

With the expansion of production scale, the screening area of ​​the equipment required for material screening (or dehydration, de-intermediation) also increases, while the screen machines of the same size screen produced at home and abroad are all single-layer screens (except Derui Overlapping high-frequency fine sieve), the structural characteristics of the single-layer sieve determine that it cannot perfectly meet the requirements of existing production development and material screening (or dehydration, de-intermediation) equipment requirements

[0003] This is because with the increase of the screening area of ​​the single-layer screen machine, the manufacturing cost and use cost of the screen machine will increase geometrically, so the screening area of ​​a single single-layer screen machine will be controlled within an economical and reasonable range. , its maximum processing capacity is limited by

The current solution is to use multiple single-layer screens in parallel to solve the problem of insufficient screening area of ​​a single screen machine; however, with the increase in the number of screen machines, the production process will be further complicated, and the construction cost of the plant and supporting facilities will be increased. , not convenient for production management and other issues
