Detailed Description
The invention will be further described with reference to the accompanying drawings, but the scope of the invention is not limited to the following description.
As shown in fig. 1 and 2, the multi-stage screening structure for slag particle size of slag comprises a plurality of stages of screening units which are connected in sequence, and the screening aperture of each screening unit is gradually reduced along the flow direction of the material.
A plurality of screening units set up along upper and lower direction, and it includes screen drum 1, and screen drum 1 supports and is provided with vibrating motor 3 on it through pillar 2, realizes the screening through the vibration. In order to realize that the materials in the screen drum 1 can be screened sufficiently, the screen drum 1 is designed to be rotatable, namely, the materials can be tumbled when the screen drum is rotated.
Specifically, the screen drum 1 comprises a large drum part in the middle and small drum parts at two ends, and the large drum and the small drum are connected through a conical shell; the big cylinder part is in a sieve mesh shape, the small cylinder part and the conical shell are not provided with sieve meshes, and the conical shell is fixed with a vibrating motor 3. The small cylinder part at the left end of the screen drum 1 is connected with the feeding bin cylinder 4 through a rotary joint 8, a belt pulley 7 is sleeved outside the small cylinder part at the left end, and the belt pulley 7 is connected with a driving motor through a belt; the opening of the small barrel part at the right end is provided with a controllable switch door 9.
A feeding bin 4 of the next level is arranged below the screen drum 1 of the previous level screening unit.
Since the screen cylinder 1 is to be vibrated, springs 203 are provided in the struts 2. After the screening is accomplished, need empty the department with the material of surplus in screen cloth cylinder 1, consequently in this scheme, the concrete structure of pillar 2 is: the pillar 2 positioned on the left side of the screen drum 1 comprises an installation body 201, a support rod 20201, a spring 203, a rotating seat 204 and a base 205 which are sequentially connected from top to bottom, a small drum part of the screen drum 1 is installed on the installation body 201 through a bearing, the rotating seat 204 is hinged on the base 205, and the base 205 is fixed on the steel frame 6; the pillar 2 on the right side of the screen drum 1, similar to the pillar 2 on the left side, includes an installation body 201, a telescopic cylinder 20202, a spring 203, a rotation seat 204, and a base 205, which are connected in sequence from top to bottom. When the material is discharged, the telescopic oil cylinder 20202 acts downwards, the right end of the screen roller 1 descends, so that the screen roller 1 rotates around the left end, and when the screen roller 1 rolls, the material in the screen roller 1 is poured out gradually.
