Description

Technical Field

[0001] This utility model relates to a liquid level adjustment mechanism for tailings troughs of magnetic separators, and belongs to the technical field of coal washing equipment. Background Technology

[0002] Media recovery, a crucial step in heavy media coal preparation, is an essential process that coal preparation plants must pay close attention to. Magnetic separators, as the main equipment in the media recovery process, bear the heavy responsibility of recovering media powder from dilute media suspensions. Reducing the media content in magnetic separation tailings is also a useful way to reduce media consumption.

[0003] The stability of the tailings tank level indirectly affects the recovery efficiency of the magnetic separator. Traditional magnetic separator tailings tanks can maintain a certain liquid level and overflow by placing a baffle plate at the bottom of the tank. However, during the production process, coarse particles in the magnetic tailings accumulate in the tailings tank, causing material to accumulate at the bottom of the tank, resulting in a "fluctuation" of the tailings tank level.

[0004] During the production process, in order to prevent blockage at the bottom of the tank while maintaining a certain liquid level, the personnel need to unclog the bottom of the tank during production to prevent material accumulation. If necessary, the tank needs to be emptied and the size of the baffle plate replaced. The above practices are time-consuming and labor-intensive. Utility Model Content

[0005] The technical problem to be solved by this utility model is to provide a liquid level adjustment mechanism for tailings tank of a magnetic separator, so as to solve the technical problems existing in the prior art.

[0006] The technical solution adopted by this utility model is as follows: a liquid level adjustment mechanism for tailings trough of a magnetic separator, including a fixed plate fixed to the bottom of the discharge port of the tailings trough. The outer periphery of the fixed plate is in contact with the inner side wall of the discharge port of the tailings trough. A fan-shaped through hole is provided on the fixed plate. A turntable is rotatably connected to the upper end of the fixed plate inside the discharge port of the tailings trough. A corresponding fan-shaped through hole is also provided on the turntable. A fixed rod is fixed radially at the upper part of the discharge port of the tailings trough. An operating rod is connected to the upper end of the turntable. The operating rod is "N" shaped. The lower left end of the operating rod vertically penetrates the fixed rod and is coaxially fixed with the turntable. The upper right end of the operating rod extends to the outside of the tailings trough opening.

[0007] Preferably, the number of the fan-shaped through holes is set to two and they are evenly distributed circumferentially about the axis of the fixed disk, and the central angle of the fan-shaped through holes is less than or equal to 90°.

[0008] Preferably, a spherical handle is fixed to the upper right end of the operating lever.

[0009] Preferably, a rectangular limiting frame is horizontally fixed on the outer side of the tailings trough opening, and the middle part of the operating rod passes through the limiting frame and can move horizontally along the limiting frame.

[0010] The beneficial effects of this utility model are as follows: Compared with the prior art, this utility model has a simple structure, is easy and flexible to operate, and saves time and labor. During the production process, the operator can adjust the tailings tank level at any time according to the throughput of the magnetic separator to maintain a stable level and reduce media loss. After this utility model was put into use in a certain mine, the media content in the tailings of the magnetic separator decreased from 1.68g / L to 0.25g / L, and the production media consumption decreased from 1.65kg / t raw coal to 1.32kg / t raw coal.

[0014] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0015] Example 1:

[0016] The liquid level adjustment mechanism of the tailings trough of the magnetic separator, such as... Figures 1-2 As shown in the solid line, a circular fixed plate 1 is fixed to the bottom of the discharge port of the tailings trough 8. The outer periphery of the fixed plate 1 is in contact with the inner wall of the discharge port of the tailings trough 8. The fixed plate 1 has two fan-shaped through holes 7, evenly distributed circumferentially about the axis of the fixed plate 1, with a central angle of 90°. A turntable 2 is rotatably connected to the upper end of the fixed plate 1 inside the discharge port of the tailings trough 8. The turntable 2 also has two corresponding fan-shaped through holes 7. During the rotation of the turntable 2, when the fan-shaped through holes 7 on the turntable 2 are aligned with the fan-shaped through holes 7 on the fixed plate 1, material is allowed to pass through. When the fan-shaped through holes 7 on the turntable 2 are completely misaligned with the fan-shaped through holes 7 on the fixed plate 1, material is not allowed to pass through. This principle of cross-alignment is used to control the liquid level inside the tailings trough 8. Figure 1 A fixing rod 3 is radially fixed at the upper part of the discharge port of the tailings trough 8 shown. An operating rod 4 is connected to the upper end of the turntable 2. The operating rod 4 is "N" shaped. The lower left end of the operating rod 4 vertically passes through the fixing rod 3 and is fixed coaxially with the turntable 2. The operating rod 4 is rotatably connected to the fixing rod 3. The upper right end of the operating rod 4 extends to the outside of the opening of the tailings trough 8. A ball-shaped handle 5 is fixed to the upper right end of the operating rod 4 for easy operation.

[0017] like Figures 1-2As shown, a rectangular limiting frame 6 is horizontally fixed on the outer side of the opening of the tailings trough 8, and the middle part of the operating rod 4 passes through the limiting frame 6 and can only move horizontally along the limiting frame 6.

[0018] In this embodiment, both the fixed disk 1 and the turntable 2 are polyurethane rubber sheets.

[0019] In this embodiment, the wiping operation lever 4 is made of Ø16 stainless steel round steel.

[0020] In this embodiment, the handle 5 is an Ø40 stainless steel ball.

[0021] Figures 1-2 The dashed section represents the existing structure of tailings trough 8.

[0022] Operators can use this invention to adjust the liquid level in tailings tank 8 according to the throughput of the magnetic separator and the liquid level in tailings tank 8. The specific adjustment process is as follows: Figure 2 During operation, the operator holds handle 5 and moves it left or right, causing operating lever 4 to rotate turntable 2. This adjusts the alignment of the sector-shaped through-hole 7 on fixed plate 1 with the sector-shaped through-hole 7 on turntable 2, thereby regulating the liquid level in tailings tank 8 to ensure it remains stable at the required level. Even when the tank is full of liquid, the valve opening can still be adjusted.

[0023] This invention can stabilize the liquid level in the tailings trough of the magnetic separator, reduce the amount of medium in the magnetic tailings, and reduce the loss of the magnetic separator medium.

[0024] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any changes or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
