Abstract
Description
Technical Field
[0001] The utility model provides a tailings slag recovery and reuse processing device, which relates to the technical field of tailings slag recovery. Background Art
[0002] Tailings refer to the remaining, no longer valuable, residue from the mineral processing process, including crushing, grinding, and sorting. These wastes typically contain small amounts of useful minerals, large amounts of gangue, and residual chemicals used in the mineral processing process. Tailings come from a wide range of sources, encompassing the mining and processing of various metallic and non-metallic ores. For example, gold, copper, iron, and coal mines all generate significant amounts of tailings after mineral processing.
[0003] There are many ways to recycle tailings, such as using advanced technology to recycle residual gold, silver, copper and other minerals, or using them in the production of various building materials after certain treatment and processing, and also for soil improvement and reclamation. Among them, when tailings are used to produce bricks, ceramics, glass and other building and decorative materials, the tailings need to be further crushed. Existing crushers can only crush tailings directly. Due to the complex composition and different sizes of tailings, if they are directly put into the crusher, the large ones will not be completely crushed and the small ones will be crushed too finely, affecting the subsequent reuse. For this reason, we propose a tailings recycling and reuse treatment device. Utility Model Content
[0004] The technical problem to be solved by the utility model is that when the existing tailings slag is recycled and crushed by a crusher, the slag size cannot be classified, resulting in poor crushing effect and affecting subsequent reuse.

[0006] Preferably, a guide shaft is also fixed to the fixed block, and the guide shaft passes through the spring and the movable block upward.
[0007] Preferably, mounting side plates are fixedly connected to both sides of the grading box, the conveyor belt is arranged between the mounting side plates, and a driving motor for driving the conveyor belt to rotate is also fixedly connected to the mounting side plates.

[0010] Beneficial effects of the utility model:
[0011] By setting up a grading mechanism, the size of the slag can be classified, and only the larger slag is crushed, while the small slag is directly collected, which improves the crushing efficiency and avoids the problem of small slag being crushed too finely and affecting subsequent reuse.
[0012] By setting up the vibration component, the impact force of the tailings slag loading can be used to drive the grading filter plate to vibrate continuously, thereby improving the filtering effect of the slag and allowing small slag to pass through the grading filter plate quickly.

[0017] The preferred embodiments of the present utility model will be described in detail below with reference to the accompanying drawings.
[0018] Reference Figures 1 to 3The present invention provides a tailings slag recycling and reuse processing device, including a crushing mechanism, which includes a crushing box 5, a crushing shaft 11 rotatably arranged inside the crushing box 5, crushing teeth 10 evenly arranged on the crushing shaft 11, and a transmission gear 6 coaxially fixed to the end of the crushing shaft 11. Two crushing shafts 11 are symmetrically arranged, and the transmission gears 6 are meshed with each other and arranged on the outside of the crushing box 5. One of the crushing shafts 11 is also coaxially fixed to a drive shaft 12. A discharge port 7 is provided at the bottom of the crushing box 5. Specifically, the drive shaft 12 is used to connect to an external drive device, which drives the crushing shafts 11 to rotate. The two crushing shafts 11 are driven by the transmission gear 6 to achieve synchronous reverse rotation, thereby crushing the tailings slag that falls into the crushing box 5.
[0019] Further, if Figure 2 As shown, a grading mechanism is provided on the top of the crushing mechanism, which includes a grading box 4 fixed to the top of the crushing box 5, a grading filter plate 9 is obliquely provided in the grading box 4, and a conveyor belt 1 is provided below the grading filter plate 9. One end of the conveyor belt 1 extends to the outside of the grading box 4. The grading filter plate 9 is evenly provided with filter holes. The top of the grading box 4 is sealed and provided with a feed port 3, which is inclined toward the top of the grading filter plate 9. Specifically, tailings are fed into the grading box 4 from the feed port 3, fall onto the top of the grading filter plate 9, and then roll down along the grading filter plate 9. During the rolling process, some fine slag can slip through the grading filter plate 9 and fall onto the conveyor belt 1 below. The conveyor belt 1 is then transported out of the grading box 4, and the large slag falls down into the crushing box 5 for crushing, thereby achieving slag size classification. Only the larger slag is crushed, and the small slag is directly sent out, avoiding the problem that the small slag is crushed together with the larger slag and is easily crushed too finely and cannot be reused.
[0020] Further, if Figure 1 、 Figure 3 As shown, a vibration assembly is provided at the top corners of the grading filter plates 9. The vibration assembly includes a support shaft 14 fixed to the top corners of the grading filter plates 9, a movable block 15 fixed to the end of the support shaft 14, and a fixed block 18 fixed to the outer wall of the grading box 4. The outer wall of the grading box 4 has an oblong hole 13 for the support shaft 14 to pass through. A spring 17 is fixed between the movable block 15 and the fixed block 18. A guide shaft 16 is also fixed to the fixed block 18, and the guide shaft 16 passes upward through the spring 17 and the movable block 15. Specifically, when slag is added to the grading filter plates 9, the impact force of the slag on the grading filter plates 9 causes the grading filter plates 9 to vibrate, thereby driving the movable block 15 to move up and down to squeeze the spring 17. The reaction force of the spring 17 then drives the grading filter plates 9 to vibrate. The vibration of the grading filter plates 9 improves the filtration effect of the slag, allowing small slag to pass through the grading filter plates 9 quickly.
[0021] Furthermore, mounting side panels 2 are fixedly connected to both sides of the grading box 4, and the conveyor belt 1 is arranged between the mounting side panels 2. A drive motor 8 for driving the conveyor belt 1 is also fixedly connected to the mounting side panels 2. Specifically, the mounting side panels 2 support and fix the conveyor belt 1, and a receiving basket for receiving small slag can be placed under the conveyor belt 1.
[0022] Working Principle: Tailings are fed into the grading box 4 from the feed port 3, fall onto the top of the grading filter plate 9, and then roll down along the grading filter plate 9. The fine slag leaks through the grading filter plate 9 and falls onto the conveyor belt 1 below. The conveyor belt 1 is then transported out of the grading box 4, while the large slag falls into the crushing box 5 for crushing, thereby achieving slag size classification and only crushing the larger slag. At the same time, through the setting of the vibration component, the impact force of the tailings feeding can be used to drive the grading filter plate 9 to vibrate continuously, improving the slag filtering effect and allowing small slag to pass through the grading filter plate 9 quickly.
[0023] The above description of the present invention and its embodiments is non-limiting. The drawings show only one embodiment of the present invention, and the actual structure is not limited thereto. In short, if a person skilled in the art is inspired by the above, and does not deviate from the purpose of the present invention, without inventive design, a structure and embodiment similar to the technical solution should fall within the scope of protection of the present invention.
