Abstract
Description
Technical Field
[0001] This utility model relates to the field of magnesium slag standard brick technology, and in particular to a screening device for magnesium slag standard brick raw materials. Background Technology
[0002] Magnesium slag is a waste residue discharged during the smelting of metallic magnesium. However, some dolomite particles are not completely calcined during the smelting process, resulting in the presence of some large gravel particles in the recovered magnesium slag. At the same time, magnesium slag is a reduction slag produced by condensing magnesium vapor through water cooling, resulting in a large amount of magnesium slag particle agglomeration. Therefore, the large number of agglomerated magnesium slag particles and gravel particles means that magnesium slag cannot be directly used in building materials and needs to be screened before it can be used.
[0003] In existing screening devices, some large particles cannot pass through the screen holes and remain on the surface of the screen plate. These large particles still need to be collected manually. At the same time, since there are many large particles and they are relatively dispersed during the screening process, manual collection is difficult and affects the screening efficiency.

[0033] The feeding device includes a first adjusting cylinder 14 and a second adjusting cylinder 15 symmetrically arranged with respect to the first adjusting cylinder 14. The first adjusting cylinder 14 is fixed vertically upward on the first support frame 10, and the second adjusting cylinder 15 is fixed vertically upward on the second support frame 11. A support plate 16 is fixed on the piston rod of the first adjusting cylinder 14 and the piston rod of the second adjusting cylinder 15, and a feeding funnel 17 is fixed on the support plate 16.
[0034] In this embodiment, the height of the feed hopper 17 can be adjusted by the first adjusting cylinder 14 and the second adjusting cylinder 15, so that the material can be accurately placed into the screening bucket 5.
[0035] A partition plate 18 is provided inside the screening frame 2 frame 1. In this embodiment, the partition plate 18 can divide the screening frame 1 into a first feeding receiving groove 19 and a second feeding receiving groove 20.
[0036] A first limiting device is horizontally provided on the first supporting plate 3. The first limiting device includes a first limiting cylinder 21, which is horizontally fixed on the first supporting plate 3 by a first U-shaped frame 23.

[0037] In this embodiment, the first adjusting cylinder 14, the second adjusting cylinder 15, the first limiting cylinder 21, and the second limiting cylinder 22 are all electric hydraulic cylinders, which adopt an integrated design and are all existing technologies.
[0038] Several push cylinders 29 are horizontally arranged on the front side of the screening frame 2 frame 1, and the piston rods of the push cylinders 29 are fixedly connected to the front side of the screening frame 2. In this example, the push cylinders 29 are used to push the screening frame 2 back and forth within the screening frame 2 frame 1 to achieve screening.
[0039] Working principle: The position of the feed hopper 17 is adjusted by the first adjusting cylinder 14 and the second adjusting cylinder 15 so that the bottom of the feed hopper 17 extends into the interior of the screening barrel 5. Then, the raw material to be screened is injected into the screening barrel 5 through the feed hopper 17. The push cylinder 29 is started to drive the screening frame 2 to move back and forth in the screening frame 2 frame 1. The movement of the screening frame 2 should be back and forth in the first discharge receiving groove 19 so that qualified particles can fall into the first discharge receiving groove 19.
[0040] After screening for a period of time, a large amount of large particles will remain in the screening barrel 5. At this time, under the action of the pushing cylinder 29, the screening barrel 5 is pushed to the top of the second feeding receiving trough 20. The position of the feeding funnel 17 is adjusted by the first adjusting cylinder 14 and the second adjusting cylinder 15 so that the bottom of the feeding funnel 17 is pulled out from the screening barrel 5, so as not to hinder the rotation of the screening barrel 5 for unloading.
[0041] Then, the first limit cylinder 21 and the second limit cylinder 22 are activated to pull the first limit block 25 out of the first docking groove 27 and the second limit block 26 out of the second docking groove 28, thereby releasing the limit on the screening barrel 5.
[0042] Start the rotating motor 9 and invert the screening barrel 5 so that the large particles collected inside fall into the second feeding receiving trough 20. After the feeding is completed, return the screening barrel 5 to the upright position.
[0043] Start the push cylinder 29. Under the action of the push cylinder 29, move the screening barrel 5 above the first feeding receiving trough 19, and perform the feeding and screening operation again.
