Wear-resistant drum screening device

Abstract

The invention discloses a wear-resistant drum screening device, which belongs to the technical field of mining industrial equipment, and comprises a main body assembly, the main body assembly comprises a drum screen, a pore diameter adjusting assembly, a protection limiting assembly, a left support plate and a right support plate, and a mounting rack I and a mounting rack II are welded at the two ends of the drum screen respectively; the driving motor is installed on one side of the left supporting plate through bolts, the mounting frame is installed on an output shaft of the driving motor, the second mounting frame is installed on one side of the right supporting plate through a rotating shaft, the number of the hole diameter adjusting assemblies is three, and each hole diameter adjusting assembly comprises a control sleeve, a control ring, an adjusting motor and a brake gear. The control sleeve and the control ring are both arranged on the rotary screen in a sleeving mode, a mounting cavity and a containing groove are formed in the control ring, the adjusting motor is installed on the inner wall of the mounting cavity through bolts, the brake gear is arranged in the containing groove, and the brake gear is installed on an output shaft of the adjusting motor.

Description

technical field [0001] The invention relates to a drum screening device, in particular to a wear-resistant drum screening device, which belongs to the technical field of mining industrial equipment. Background technique [0002] Slag is a by-product of the blast furnace ironmaking process. In the process of ironmaking, iron oxide is reduced to metallic iron at high temperature, and impurities such as silica and alumina in iron ore react with lime to form a melt with silicate and aluminosilicate as the main components. After being quenched into loose and porous granular matter, it is blast furnace slag, referred to as slag. In industrial production, slag plays an important role, especially in some large factories, which use slag to refine and process it into slag cement and slag. Micropowder, slag powder, slag portland cement, slag cotton, blast furnace slag, granulated blast furnace slag powder, copper slag, etc., slag can be classified in different ways, and can be divided...

AI Technical Summary

Problems solved by technology

[0003] Generally, slag needs to be screened by trommel sieve. The application number is 201720589683.8, which provides an improved trommel sieving machine, which is a commonly used trommel sieve. There are some shortcomings in the use of this trommel sieve, and multi-stage sieves are sometimes required for slag screening. The trommel screen can achieve multi-stage sub-sieving, but the size of the sieve hole is fixed, so there are great limitations in use, and it cannot be flexibly adjusted according to the demand, and the minerals are prone to accumulation when moving inside, and there are small particles on the top The slag is easy to be discharged with large particles of slag, and driven by the motor, the slag hits the inner wall very violently, so the inner wall is easily damaged, and part of the slag will also be crushed, which will increase the number of small particles of slag, and once the slag appears inside The stuck situation cannot be detected in time, so it will also cause damage to the inner wall
