Description

Technical Field

[0001] This utility model relates to the field of tailings screening technology, specifically a screening mechanism for tailings treatment. Background Technology

[0002] Tailings, also known as tailings, are one of the products of mineral processing, and the part with the lowest content of useful target components is called tailings.

[0003] Chinese patent application CN202321507937.9 discloses a tailings treatment and screening mechanism. The key technical features include a base plate with two support plates fixedly connected to its top surface. The left support plate is taller than the right support plate. Each support plate has a rotatably connected annular plate to its sidewall. Several crossbars are fixedly connected to the opposite ends of the two annular plates. A driving assembly is installed on the sidewall of the left support plate. A hopper is located on the left side of the left annular plate, with a U-shaped baffle fixedly connected to its top end. The hopper extends into the inner side of the annular plate. A reinforcing plate is fixedly connected between the hopper and the base plate. A washing assembly is installed on the upper side of the crossbars. This mechanism effectively solves the problem of inconvenient washing of ore during screening in existing methods.

[0004] In existing and above-mentioned screening mechanisms, tailings can get stuck between the crossbars during use. Due to the lack of cleaning devices and the large size of the tailings screening devices, the cleaning process is very inconvenient for workers. Therefore, a screening mechanism for tailings treatment is proposed to address the above problems. Utility Model Content

[0005] In order to overcome the shortcomings of the existing technology and solve at least one technical problem in the background technology, this utility model proposes a screening mechanism for tailings treatment.

[0006] The technical solution adopted by this utility model to solve its technical problem is as follows: The screening mechanism for tailings treatment described in this utility model includes a base plate, a drum and a motor. The drum is rotatably connected to the surface of the base plate. A crossbar is fixedly connected to the surface of the drum. The drum and the motor are connected by gear meshing and driven by the motor.

[0007] A roller is rotatably connected to the surface of a base plate via a bearing. A lever is provided on the surface of the roller, and the roller is driven by a motor.

[0008] The top plate has a groove on its surface, and the top plate is movably connected to the groove on the surface of the lever by a spring.

[0009] The top plate is positioned between two horizontal bars;

[0010] The dial plate is equipped with a vibration mechanism for cleaning residues on the top plate surface.

[0011] Preferably, the roller is positioned above the drum, and the surface of the roller is provided with gears, which mesh with gears on the surface of the drum.

[0012] Preferably, a sliding rod is fixedly connected to the surface of the top plate, a protrusion is fixedly connected to the surface of the sliding rod, and a groove is formed on the inner wall of the groove on the surface of the lever plate relative to the position of the protrusion.

[0013] Preferably, the vibration mechanism includes an impact head, which is movably connected within a top plate. A limit rod is fixedly connected to the surface of the lever, and a top shaft is fixedly connected to the surface of the limit rod. The impact head is slidably connected to the surface of the limit rod via a spring. A sliding rod is slidably connected to a groove on the surface of the lever via a spring. A limit rod is fixedly connected to the surface of the lever, and a top shaft is fixedly connected to the surface of the limit rod. A cavity is formed inside the impact head, and an insert block is slidably connected to the cavity via a spring piece. A slot is formed on the surface of the sliding rod relative to the position of the insert block, and a through hole is formed on the side wall of the cavity.

[0014] Preferably, there are two insert blocks, and the pair of insert blocks are symmetrically distributed about the central axis of the top shaft.

[0015] Preferably, the number of the levers is an integer multiple of the number of crossbars.

[0016] Preferably, the base plate is rotatably connected to the surface of the base plate by a thread, and the surface of the base plate is bonded with an anti-slip pad.

[0017] The advantages of this utility model are:

[0018] 1. This utility model uses a top plate to clear stones stuck between crossbars, solving the problem of workers having difficulty cleaning large screening equipment. If the stones are stuck tightly, because the top plate is a movable connection, it will retract towards the push plate to skip the stones, thus avoiding the push plate from breaking. Because the roller is set above the drum, the stones can be directly pushed out, avoiding excessive stone accumulation and increasing the resistance of the top plate pushing out.

[0019] 2. This utility model achieves an impact effect by using the vibration generated when the impact head strikes the top plate, thereby further improving the cleaning effect on stones. Attached Figure Description

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] Example 1

[0029] Please see Figure 1-4 As shown, a screening mechanism for tailings treatment includes a base plate 1, a drum 2 and a motor 3. The drum 2 is rotatably connected to the surface of the base plate 1, and a crossbar 8 is fixedly connected to the surface of the drum 2. The drum 2 and the motor 3 are connected by gear meshing and are driven by the motor 3.

[0030] Roller 5 is rotatably connected to the surface of base plate 1 via bearing 6. A lever 7 is provided on the surface of roller 5. Roller 5 is driven by motor 3.

[0031] The top plate 9 and the lever plate 7 have grooves on their surfaces, and the top plate 9 is movably connected to the lever plate 7 within the grooves on its surface by a spring.

[0032] The top plate 9 is positioned between the two horizontal bars 8;

[0033] The paddle plate 7 is equipped with a vibration mechanism to clean the residue on the surface of the top plate 9. The roller 5 is located above the drum 2. The surface of the roller 5 is equipped with gears, which mesh with the gears on the surface of the drum 2. The number of paddle plates 7 is an integer multiple of the number of crossbars 8.

[0034] During operation, motor 3 drives drum 2 to rotate, and drum 2 drives roller 5 to rotate. Because the number of crossbars 8 is an integer multiple of the number of levers 7, when roller 5 drives lever 7 to move, lever 7 can be stuck between two crossbars 8. When lever 7 moves between two crossbars 8, if there are stones between the crossbars 8, lever 7 will drive top plate 9 to push the stones out. The top plate 9 clears the stones stuck between the crossbars 8, solving the problem of workers not being able to clean large screening equipment. If the stones are stuck tightly, because top plate 9 is a movable connection, top plate 9 will retract towards lever 7 to skip the stones, thus avoiding the situation where lever 7 is broken. Because roller 5 is set above drum 2, it can directly push the stones out, avoiding excessive stone accumulation and increasing the resistance of top plate 9 in pushing them out.

[0035] A slide rod 12 is fixedly connected to the surface of the top plate 9, and a protrusion is fixedly connected to the surface of the slide rod 12. A groove is opened in the inner wall of the groove on the surface of the lever plate 7 relative to the position of the protrusion. During operation, the protrusion can play a limiting role to prevent the top plate 9 from overtraveling.

[0036] The vibration mechanism includes an impact head 11, which is movably connected within the top plate 9. A limit rod 13 is fixedly connected to the surface of the lever plate 7, and a top shaft 15 is fixedly connected to the surface of the limit rod 13. The impact head 11 is slidably connected to the surface of the limit rod 13 via a spring. A slide rod 12 is slidably connected to a groove on the surface of the lever plate 7 via a spring. A limit rod 13 is fixedly connected to the surface of the lever plate 7, and a top shaft 15 is fixedly connected to the surface of the limit rod 13. A cavity 17 is provided inside the impact head 11, and an insert block 16 is slidably connected to the cavity 17 via a spring piece 19. A slot is provided on the surface of the slide rod 12 relative to the position of the insert block 16. A through hole 18 is provided on the side wall of the cavity 17. Two insert blocks 16 are provided, and a pair of insert blocks 16 are symmetrically distributed about the central axis of the top shaft 15.

[0037] During operation, when the top plate 9 retracts to its limit position, the top shaft 15 will be inserted into the through hole 18 and extend into the cavity 17. Then, under the action of the top shaft 15, the spring piece 19 will be squeezed and deformed. At this time, the two inserts 16 will move towards each other and disengage from the slot. After the limit is released, the spring will drive the impact head 11 to pop out and impact the top plate 9. The vibration generated by the impact head 11 hitting the top plate 9 further improves the cleaning effect on the stone.

[0038] Example 2

[0039] Please see Figure 5 As shown in the first embodiment, as another implementation of this utility model, the base plate 1 is connected to the base 21 by a threaded connection, and the base 21 is bonded with an anti-slip pad. During operation, the base 21 connected by the thread can adjust the level of the base plate 1, and with the anti-slip pad, it can be placed more stably on uneven ground.
