Embodiment

[0024] The steel slag horizontal vibrating screen of this embodiment is such as figure 1 , figure 2 , image 3 with Figure 4 As shown, it includes a frame 1 and a vibrating screen 3. The lower silo is fixedly connected to the frame 1, and a support spring 2 is used to support the vibrating screen 3 on the top of the frame, and the vibration exciter 4 is fixedly installed on the vibrating screen 3. The top screen 5 and the middle screen 6 are installed inside the vibrating screen 3. The surface area of ​​the two-layer screen reaches 8 square meters, and the top of the lower silo 7 receives the middle screen 6. The lower bin 7 is in the shape of a small bucket up and down, with an inclined output port at the bottom, and a conveyor belt arranged obliquely below the output port. The two-layer screens are designed with different apertures, and screen quickly during the vibration process. The supporting spring 2 corresponds to the mounting bosses on the four corners of the vibrati...

Abstract

The invention provides a horizontal vibration screen of steel slag and a triple screening method. The device comprises a frame and a vibration screen, wherein a discharging bin is arranged on the frame; the vibration screen is supported at the top end of the frame through support springs; a vibration exciter is fixedly mounted on the vibration screen; a top screen mesh and a middle screen mesh aremounted in the vibration screen; the middle screen mesh is supported on the top of the discharging bin; an oblique outlet opening is formed in the bottom of the discharging bin; an oblique conveyingbelt is arranged under the output opening. The method is characterized by screening the steel slag into three particle sizes; materials with size being greater than 60mm are screened on the top screenmesh; materials with size of 10-60mm are screened from remaining materials by the middle screen mesh; materials with size being smaller than 10mm fall into the discharging bin; the oblique conveyingbelt arranged at the bottom of the discharging bin is used for carrying the materials away. The overall process arrangement achieves the characteristics of high efficiency, energy economization and environment friendliness; the problem of coagulation of scrap iron in the tailing slag is also mainly solved; meanwhile, the horizontal vibration screen is high in reliability and convenient in on-sitemaintenance.

Description

Technical field [0001] The invention relates to the treatment of molten steel smelting slag, in particular to a steel slag horizontal vibrating screen and a triple screening method. Background technique [0002] The compressive strength of steel slag is 169~306MPa, the Mohs hardness is 5~7, and the texture is hard to break and grind. Because steel slag is relatively dense, high in hardness, and has a special structure, it is a combination of iron and slag. Some particles are slag-clad iron, some are iron-clad slag, and even iron lumps with relatively large particle size. Granular steel slag needs to be sorted by efficient screening equipment. [0003] After searching, Chinese patent document CN106076810A discloses a horizontal three-axis vibrating screen, which includes a screen box assembly, a base and an excitation system. The screen box assembly is provided with an inlet and a discharge nozzle, and the inlet is provided with a bearing The box, the excitation system is connecte...
