Description

Technical Field

[0001] The utility model relates to the technical field of steel slag magnetic separation and screening process, and specifically relates to a screening structure for mixed material production. Background Art

[0002] Steel slag is a by-product of the steelmaking process. It is composed of various oxides formed by the oxidation of impurities such as silicon, manganese, phosphorus, and sulfur in pig iron during the smelting process, as well as salts generated by the reaction of these oxides with solvents. Steel slag contains a variety of useful ingredients: metallic iron, calcium oxide, magnesium oxide, and manganese oxide, so it can be used as a raw material for steel metallurgy. The mineral composition of steel slag is mainly tricalcium silicate, followed by dicalcium silicate, RO phase, dicalcium ferrite, and free calcium oxide. Steel slag is clinker and a remelting phase with a low melting temperature. When remelted, the liquid phase is formed early and has good fluidity. The slag magnetic separation and screening process refers to the process in which the hot poured steel slag is watered and simmered, and when the temperature and moisture meet the technical requirements, it is transported to the designated yard of the magnetic separation workshop, and the slag below 300 mm is loaded by shovel equipment through the grid screen to enter the magnetic separation and screening production line. After magnetic separation and screening, slag steel and tailings of different specifications are selected. In the actual slag magnetic separation and screening, the grid screen is used for preliminary screening, which is not only prone to incomplete screening, but the screened slag also needs to be loaded and transported again before it can enter the magnetic separation and screening steps, which is time-consuming and labor-intensive.

[0017] The platform plate 2 fixes the shell 1, and a support leg 3 is arranged on the bottom surface of the platform plate 2. The support leg 3 is relatively long, and the shell 1 is installed at a higher position, so that a magnetic separator and other equipment can be placed under the hopper 4. After the mixed material is screened, it falls out from the position of the hopper 4 and directly enters the magnetic separator and other equipment, eliminating the steps of re-loading, saving time and effort, and using the loading equipment to put the mixed material of steel slag into the interior of the sleeve 8. The sleeve 8 is in an inclined device, and the external power supply of the motor 6 is turned on. The motor 6 drives the rotating drum 7 to rotate. The rotating drum 7 is connected to the sleeve 8 through the fixed frame 9. As the sleeve 8 rotates continuously, the mixed material is continuously contacted to achieve the purpose of screening. The screened steel slag enters the larger hopper 4, and the screened steel slag that cannot pass through the grid on the sleeve 8 finally falls out from the right side of the sleeve 8 as shown in the figure, enters the larger hopper 4 for discharge, and is simple to operate and easy to use.

[0018] Specifically, a second bracket 11 is fixedly mounted on the other side of the platform plate 2 , and a material guide trough 10 is fixedly mounted on the second bracket 11 . The material guide trough 10 extends into the sleeve 8 .

[0019] A second bracket 11 is installed at the end of the platform plate 2 away from the motor 6. The second bracket 11 fixes the material guide trough 10. During the loading process, a conveyor belt or other loading equipment is used to put the mixed material into the inside of the material guide trough 10. Under the action of gravity, the mixed material enters the sleeve 8 along the inner wall of the material guide trough 10.

[0020] Specifically, a partition net 14 is fixedly mounted on the inner wall of the sleeve 8 , the rotating drum 7 passes through the partition net 14 , and the partition net 14 is located above the partition plate 12 .

[0021] A partition 14 is arranged on the inner wall of the sleeve 8. The mesh diameter of the partition 14 is relatively large. When the mixture is screened, it can pass through the partition 14. The partition 14 can increase the storage time of the mixture in the sleeve 8 to achieve the purpose of uniform screening.

[0022] Specifically, a frame 17 is movably installed on the inner wall of the outer shell 1, and a net bag 18 is fixedly installed on the inner wall of the frame 17.

A protrusion is provided on the side of the frame 17, and one end of a spring 19 is fixedly installed on the bottom surface of the protrusion. A support 20 is fixedly installed on the other end of the spring 19, and the support 20 is fixedly installed on the inner wall of the outer shell 1.

[0023] A frame 17 is provided below the position where the sleeve 8 and the material guide groove 10 are connected, and a net bag 18 is installed on the frame 17. The net bag 18 is mainly used to catch the mixture that accidentally falls. The net bag 18 screens this part of the mixture. A spring 19 is installed on the side of the frame 17. The spring 19 can undergo elastic deformation under pressure, thereby increasing the frequency of the up and down movement of the net bag 18. As the net bag 18 continues to move, the purpose of screening the mixture in the net bag 18 is achieved.

[0024] Specifically, a slide groove 15 is formed on the inner wall of the housing 1 , a slider 16 is slidably engaged with the inner wall of the slide groove 15 , and the slider 16 is fixedly assembled with the frame 17 .

[0025] In order to make the frame 17 move more stably, a slide groove 15 is opened on the inner wall of the shell 1, and a slider 16 is slidably engaged in the slide groove 15. The slider 16 can move in the slide groove 15 along with the movement of the frame 17, so that the frame 17 drives the net bag 18 to move more stably.

[0026] Specifically, a spherical groove is formed on the surface of the partition plate 12 , and a ball 13 is clamped in the spherical groove. The ball 13 is in contact with the sleeve 8 .

[0027] A ball 13 is rolled on the partition 12 , and the ball 13 and the sleeve 8 are fitted together. During the rotation of the sleeve 8 , the ball 13 continuously rolls, which can reduce the friction between the sleeve 8 and the partition 12 .

[0028] Working principle: A magnetic separator and other equipment are placed under the hopper 4. After the mixture is screened, it falls out of the hopper 4 and directly enters the magnetic separator and other equipment, eliminating the steps of re-loading, saving time and effort.

The motor 6 drives the rotating drum 7 to rotate. The rotating drum 7 is connected to the sleeve 8 through the fixed frame 9. As the sleeve 8 rotates continuously, the mixture is constantly in contact, thereby achieving the purpose of screening. The screened slag enters the larger hopper 4.
