Description

Technical Field

[0001] The utility model relates to the technical field of aluminum separation in slag, in particular to a device for separating aluminum particles in slag. Background Art

[0002] As general waste, slag can be directly disposed of in landfills or, after appropriate treatment, be recycled, for example, by recovering the metals within or using it as roadbed material. Slag produced by waste incineration power generation often contains aluminum particles. Scrap aluminum is a valuable resource, and its effective recycling and utilization are crucial for developing a circular economy, conserving resources and energy, and reducing greenhouse gas and hazardous substance emissions.

[0003] For example, the Chinese patent publication number CN217940467U discloses a highly efficient separation device for aluminum particles in slag. This patent drives the separation magnetic roller to rotate through a first motor. The interior of the aluminum metal in the slag around the separation magnetic roller will induce eddy currents, causing the aluminum metal to leap to the surrounding areas inside the separation box due to the repulsive force of the magnetic field. The leaping aluminum metal will be discharged from the interior of the separation box through the first metal outlet and the second metal outlet under the action of gravity. The slag can be separated by moving downward in the interior of the separation box with the help of gravity, saving energy consumption.

[0004] However, the technical solution disclosed in the above patent still has shortcomings. Since the upper end of the sorting magnetic roller passes through the material hole and extends into the aggregate trough, the aluminum particles in the slag in the aggregate trough are easily moved away from the material hole under the action of the magnetic field, causing the aluminum particles to repeatedly fly in the aggregate trough and unable to pass through the material hole. The slag is easily accumulated together, affecting the aluminum selection effect. At the same time, the slag in the material hole is prone to friction and collision with the sorting magnetic roller, causing damage to the sorting magnetic roller. Utility Model Content

[0013] Preferably, the bottom diameter of the material separation seat is larger than the diameter of the separation magnetic roller, the separation magnetic roller is located above the discharge hopper, and the diameter of the top port of the discharge hopper is larger than the diameter of the bottom port of the discharge tube cover. As the slag falls, it will not come into contact with the separation magnetic roller and will fall into the discharge hopper.

[0014] Preferably, the sorting box is cylindrical, the bottom of the sorting box is open, and a discharge gap is provided between the bottom inner wall of the sorting cavity and the outer wall of the discharge hopper. Under the magnetic force of the sorting magnetic roller, the aluminum particles that are bounced off can be discharged through the discharge gap.

[0031] A sorting box 1 is provided with a sorting chamber 2 inside the sorting box 1, a feeding chamber 3 is provided above the sorting chamber 2, a feeding hopper 4 is provided between the feeding chamber 3 and the sorting chamber 2, and a discharge barrel cover 5 is fixedly sleeved on the bottom of the feeding hopper 4;

[0032] The first motor 6 is installed on the top of the sorting box 1. The output end of the first motor 6 is connected to the rotating shaft 19. The lower end of the rotating shaft 19 passes through the feeding hopper 4 and is connected to the material distribution seat 7. The lower part of the rotating shaft 19 is fixedly sleeved with an auger 8;

[0033] The discharge hopper 9 is nested at the bottom of the sorting chamber 2. A second motor 10 is nested in the discharge hopper 9. The output end of the second motor 10 is connected to a sorting magnetic roller 11. The upper end of the sorting magnetic roller 11 is rotatably connected to the bottom of the sorting seat 7.

[0034] The discharge bottom cover 12 is arranged at the bottom of the sorting box 1 , and a discharge port 13 is opened at the left end of the discharge bottom cover 12 .

[0035] A feed hopper 14 is provided on the top of the sorting box 1 . The inner cavity of the feed hopper 14 is connected to the feed cavity 3 . The top edge of the feed hopper 4 is fixedly connected to the inner wall of the sorting box 1 .

[0036] The auger 8 is nested in the feed hopper 4, and the distribution seat 7 is nested in the discharge barrel cover 5.

A feeding gap is provided between the outer wall of the distribution seat 7 and the inner wall of the discharge barrel cover 5. The auger 8 rotates to evenly transport the feed hopper 4, and then the materials are dispersed and dropped through the feeding gap.

[0037] The sorting box 1 is cylindrical with an open bottom. A discharge gap is provided between the bottom inner wall of the sorting cavity 2 and the outer wall of the discharge hopper 9. Under the magnetic force of the sorting magnetic roller 11, the aluminum particles that are bounced off can be discharged through the discharge gap.

The protective box 16 protects the second motor 10 to prevent the slag from contacting the second motor 10 .

[0039] In the present invention, the slag to be sorted is poured into the feed chamber 3 through the feed hopper 14, and then the slag falls onto the feed hopper 4. The first motor 6 and the second motor 10 work, and the second motor 10 drives the sorting magnetic roller 11 to rotate. The first motor 6 drives the rotating shaft 19 to rotate, and the rotation of the rotating shaft 19 drives the auger 8 and the material distribution seat 7 to rotate. The auger 8 rotates to evenly transport the slag in the feed hopper 4, so that the slag falls evenly onto the material distribution seat 7. The material distribution seat 7 rotates to disperse the slag, and the dispersed slag passes through the feed hopper 4. The slag falls evenly through the feeding gap between the outer wall of the material distribution seat 7 and the inner wall of the discharge barrel cover 5. When passing through the sorting magnetic roller 11, the aluminum particles in the slag are bounced off by the magnetic field generated by the sorting magnetic roller 11, and then fall onto the discharge bottom cover 12 through the discharge gap between the bottom inner wall of the sorting chamber 2 and the outer wall of the discharge hopper 9.

[0041] In the present utility model, the bottom diameter of the material distribution seat 7 is larger than the diameter of the sorting magnetic roller 11, and the dispersed slag falls evenly through the feeding gap between the outer wall of the material distribution seat 7 and the inner wall of the discharge barrel cover 5, without contacting the sorting magnetic roller 11 and causing damage to the sorting magnetic roller 11, thereby protecting the sorting magnetic roller 11, and the top port diameter of the discharge hopper 9 is larger than the bottom port diameter of the discharge barrel cover 5, so that the vertically falling slag can fall into the discharge hopper 9 for collection.

[0042] like Figure 1 and Figure 2 As shown, the inner bottom wall of the discharge bottom cover 12 is set to an inclined structure with the left side lower and the right side higher, and a plurality of fixing plates 15 are connected between the discharge bottom cover 12 and the sorting box 1.

[0043] The lower end of the discharge hopper 9 passes through the discharge bottom cover 12. A first support rod 17 is provided between the side wall of the discharge hopper 9 and the bottom wall of the sorting chamber 2, so that the discharge hopper 9 is installed stably and the sorting box 1 is installed stably.

[0044] In the present invention, the inner bottom wall of the discharge bottom cover 12 is set to an inclined structure with the left side lower and the right side higher. The aluminum particles sorted by the sorting box 1 fall into the discharge bottom cover 12, and then slide to the left end of the discharge bottom cover 12 and are discharged from the discharge port 13. At the same time, the lower end of the discharge hopper 9 passes through the discharge bottom cover 12, and the slag discharged by the discharge hopper 9 falls directly to the bottom of the discharge bottom cover 12, thereby realizing the classified collection of the slag and the aluminum particles in the slag, which is convenient for later processing.
