Description

Technical Field

[0001] This utility model belongs to the technical field of discharge devices, specifically relating to a continuous discharge device for low-manganese titanium slag. Background Technology

[0002] Low-manganese titanium slag is a molten slag obtained by smelting ilmenite in an electric furnace. It is mainly composed of titanium compounds and has a relatively low manganese content. During the electric furnace smelting process, the temperature usually needs to be controlled at around 1600-1800℃. This temperature range is conducive to the full decomposition of ilmenite and the enrichment of titanium compounds, while ensuring that manganese elements are separated as much as possible, thus obtaining low-manganese titanium slag.

[0003] A related technology (publication number CN201233179Y) discloses a slag outlet for a titanium slag electric furnace, comprising a main channel constructed of magnesia bricks. The outlet end of the main channel is equipped with a slag nozzle made of a high-temperature resistant and corrosion-resistant material. The slag outlet channel in the nozzle is connected to the main channel to form a channel. The slag outlet has good resistance to high-temperature corrosion, providing insulation for the magnesia bricks and greatly mitigating damage caused by rapid heating and cooling, thus significantly extending the service life of the slag outlet. This invention is applicable to slag outlets in titanium slag electric furnaces, submerged arc furnaces, ferroalloy furnaces, etc.

[0004] Currently, the discharge port size of existing low-manganese titanium slag discharge equipment is fixed and the opening angle cannot be adjusted. When the flow rate of low-manganese titanium slag is large and the discharge port is small, blockage is likely to occur. When the flow rate of low-manganese titanium slag is small and the discharge port is large, a small amount of titanium slag is unevenly distributed in the large area of ​​the discharge port space, resulting in a lack of continuity in the flow of materials. Utility Model Content

[0005] To address the problems of existing low-manganese titanium slag discharge equipment having a fixed discharge port size and inability to adjust the opening angle, this invention provides a continuous low-manganese titanium slag discharge device. During the descent of the low-manganese titanium slag along the discharge port, the device automatically detects the discharge rate and adjusts the opening and closing of the cover based on the flow rate and accumulation of the slag, ensuring continuous discharge. When the slag flow rate is high, the cover automatically opens wider to prevent blockage; when the slag flow rate is low, the cover closes appropriately to maintain stable discharge and reduce discontinuous discharge. The specific technical solution is as follows:

[0006] A continuous discharge device for low-manganese titanium slag includes a storage tank. A controller is installed on the side wall of the storage tank. Multiple support arms are vertically arranged at the bottom of the storage tank. A discharge port is inclined downward at the bottom of the side wall of the storage tank. A flow monitoring component and an opening and closing component are installed inside the discharge port. The flow monitoring component detects the flow rate of low-manganese titanium slag in the discharge port and transmits the signal to the controller for processing. The controller then controls the opening and closing component to open in the corresponding direction. A fixed base is installed above the discharge port. A cover is rotatably connected to the fixed base via a rotating shaft. The cover rotates to cover the right output port of the discharge port. The opening and closing angle of the cover is controlled by the opening and closing component.

[0007] In the above technical solution, the monitoring component includes a mounting base fixedly installed at the bottom of the inner wall of the discharge port. A swing rod is rotatably arranged inside the mounting base. A circular plate is fixedly installed on the swing rod. A lever is fixedly installed on the circular plate. Multiple elastic lever triggers are equidistantly arranged at the top of the inner wall of the storage tank. The multiple elastic lever triggers gradually rise downwards along the inner wall of the discharge port. A leaf spring is arranged inside the mounting base. The leaf spring is connected to the swing rod and the mounting base respectively.

[0008] The elastic paddle trigger is electrically connected to the controller.

[0009] In the above technical solution, the opening and closing component includes a mounting frame fixedly installed on the discharge port. A first motor is installed on the left side wall of the mounting frame. The first motor is electrically connected to the controller. A lead screw is connected to the output end of the first motor, and the lead screw is rotatably connected to the side wall of the mounting frame. A limit rod is fixedly installed inside the mounting frame, and the limit rod is arranged parallel to the lead screw. A movable seat is threaded on the lead screw, and the movable seat is slidably sleeved on the limit rod. A connecting rod is rotatably connected to the movable seat.

[0010] The connecting rod is rotatably connected to the right side wall of the cover.

[0011] In the above technical solution, a mixing unit is provided inside the storage tank. The mixing unit includes a rotating shaft arranged vertically inside the storage tank. Multiple sets of mixing components are equidistantly arranged on the rotating shaft. Each set of mixing components includes three pillars fixedly installed on the rotating shaft. A ring is fixedly installed on the outside of the pillars. Multiple semi-ring plates are equidistantly installed on the sidewall of the ring along the circumferential direction.

[0012] In the above technical solution, each of the semi-annular pieces is configured as a curved arc.

[0013] In the above technical solution, a drive unit is provided at the top of the rotating shaft. The drive unit includes a second pulley fixedly installed at the top of the rotating shaft, and a motor frame fixedly installed on the right side wall of the storage tank. A second motor is installed on the motor frame. The output end of the second motor is connected to a drive shaft. A first pulley is installed on the drive shaft. Belts are fitted on the first pulley and the second pulley.

[0014] In the above technical solution, the top of the storage tank is connected to a feed inlet.

[0015] The continuous discharge device for low-manganese titanium slag of this utility model has the following advantages compared with the prior art:

[0016] I. In view of the problem that the discharge port size of existing low-manganese titanium slag discharge equipment is fixed and the opening angle cannot be adjusted, this utility model can automatically detect the discharge volume of low-manganese titanium slag as it falls along the discharge port. Based on the flow rate and accumulation of low-manganese titanium slag, the opening and closing size of the cover is automatically adjusted to ensure the continuity of discharge. When the flow rate of low-manganese titanium slag is large, the cover automatically opens wider to avoid blockage. When the flow rate of titanium slag is small, the cover is appropriately closed to maintain stable discharge and reduce the phenomenon of discontinuous discharge.

[0017] II. This utility model uses a swing rod, a circular plate, a lever, a leaf spring, and multiple elastic lever triggers to automatically detect different levels of low manganese titanium slag feeding and transmit the detection signal to the controller for processing, so as to control the direction of rotation of the first motor and thus control the degree of opening and closing of the cover.

[0018] Third, this utility model, through the rotating shaft, support column, ring body, and semi-ring plate, can continuously stir the low-manganese titanium slag in the storage tank and continuously push the low-manganese titanium slag towards the discharge port, while breaking up the clumps formed by the low-manganese titanium slag, ensuring that the low-manganese titanium slag is always in a flowable state, which helps to improve the continuity of discharge, so that the low-manganese titanium slag can flow out of the discharge port evenly, and reduce the interruption of discharge caused by local accumulation of low-manganese titanium slag.

[0019] In summary, this invention can automatically detect the discharge rate of low-manganese titanium slag as it falls along the discharge port. Based on the flow rate and accumulation of the slag, the opening and closing of the cover is automatically adjusted to ensure continuous discharge. When the slag flow rate is high, the cover automatically opens wider to prevent blockage; when the slag flow rate is low, the cover closes appropriately to maintain stable discharge and reduce discontinuous discharge. Furthermore, it continuously stirs the slag in the storage tank and pushes it towards the discharge port, breaking up any agglomerates and ensuring the slag remains in a flowable state. This helps improve the continuity of discharge, allowing the slag to flow out evenly from the discharge port and reducing discharge interruptions caused by localized accumulation of slag.

[0026] The following are specific implementation cases and appendices. Figures 1 to 5 The present invention will be further described below, but the present invention is not limited to these embodiments.

[0027] Main references Figures 1 to 5 As shown, a continuous discharge device for low-manganese titanium slag includes a storage tank 1, a controller 2 installed on the side wall of the storage tank 1, and multiple support arms 3 vertically arranged at the bottom of the storage tank 1. A discharge port 5 is inclined downward at the bottom of the side wall of the storage tank 1. The low-manganese titanium slag in the storage tank 1 is discharged to the outside through the discharge port 5. A flow monitoring component and an opening and closing component are installed in the discharge port 5. The flow monitoring component detects the flow rate of the low-manganese titanium slag in the discharge port 5 and transmits the signal to the controller 2 for processing, and controls the opening and closing component to open in the corresponding direction. A fixed base 18 is installed above the discharge port 5. The fixed base 18 is rotatably connected to a cover 19 via a rotating shaft. The cover 19 rotates to cover the right output port of the discharge port 5. The opening and closing angle of the cover 19 is controlled by the opening and closing component. When the flow rate of the low-manganese titanium slag is large, the cover 19 automatically opens to avoid blockage. When the flow rate of the titanium slag is small, the cover 19 is appropriately closed to maintain stable discharge and reduce discontinuous discharge.

[0028] Main references Figures 2 to 4 As shown, the monitoring component includes a mounting base 6 fixedly installed at the bottom of the inner wall of the discharge port 5. A swing rod 7 is rotatably mounted inside the mounting base 6. A circular disc 8 is fixedly mounted on the swing rod 7, and a lever 9 is fixedly mounted on the circular disc 8. Multiple elastic lever triggers 10 are equidistantly arranged at the top of the inner wall of the storage tank 1, and these triggers gradually rise downwards along the inner wall of the discharge port 5. A leaf spring 11 is installed inside the mounting base 6, and the leaf spring 11 is connected to both the swing rod 7 and the mounting base 6. The elastic lever triggers... The trigger 10 is electrically connected to the controller 2; the elastic paddle trigger 10 is a commonly used trigger in the market. It consists of a paddle with its own elasticity and a pressure device. When the paddle is forced to deform, it can trigger the pressure device. The pressure device transmits a signal to the controller 2 for processing, indicating that the lever 9 is impacted by the low manganese titanium slag and touches the corresponding position of the elastic paddle trigger 10. When the lever 9 is disengaged from the action of the elastic paddle trigger 10, the elastic paddle trigger 10 can automatically return to its initial state under the action of the leaf spring 11.

[0029] Main references Figure 2 and Figure 3 As shown, the opening and closing assembly includes a mounting frame 12 fixedly installed on the discharge port 5. A first motor 13 is installed on the left side wall of the mounting frame 12. The first motor 13 is electrically connected to the controller 2. The output end of the first motor 13 is connected to a lead screw 14, and the lead screw 14 is rotatably connected to the side wall of the mounting frame 12. A limit rod 15 is fixedly installed inside the mounting frame 12, and the limit rod 15 is arranged parallel to the lead screw 14. A movable seat 16 is threaded on the lead screw 14, and the movable seat 16 is slidably sleeved on the limit rod 15. The movable seat 16 is rotatably connected to a connecting rod 17. The connecting rod 17 is rotatably connected to the right side wall of the cover 19.

[0030] After being processed inside the storage tank 1, the low-manganese titanium slag flows downward through the discharge port 5. During the flow of the low-manganese titanium slag, the impact force on the disc 8 varies depending on the output amount of low-manganese titanium slag. When the amount of low-manganese titanium slag discharged is large, the disc 8 is impacted more significantly, causing the swing rod 7, disc 8, and lever 9 to swing clockwise synchronously to a larger amplitude. This causes the lever 9 to sequentially activate multiple spring-loaded trigger 10s. The activated spring-loaded trigger 10s transmit signals to the controller 2 for processing. 2. The first motor 13 is turned on, which drives the lead screw 14 to rotate, so that the moving seat 16 moves to the right and downward along the lead screw 14 and the limit rod 15, which drives the connecting rod 17 and the rotating connection of the moving seat 16 to move downward, and drives the cover 19 to open counterclockwise to a larger angle with the rotating connection of the cover 19 and the fixed seat 18 as the axis; through the impact of the disc 8 by the low manganese titanium slag of different feed amounts, the lever 9 is activated to move different numbers of spring-loaded triggers 10, so that the cover 19 opens to different angles.

[0031] Main references Figure 1 and Figure 5 As shown, a mixing unit is provided inside the storage tank 1. The mixing unit includes a rotating shaft 20 arranged vertically inside the storage tank 1. Multiple mixing components are equidistantly arranged on the rotating shaft 20. Each mixing component includes three support columns 21 fixedly installed on the rotating shaft 20. A ring body 22 is fixedly installed on the outside of the support column 21. Multiple semi-ring plates 23 are equidistantly installed on the side wall of the ring body 22 along the circumference. Each semi-ring plate 23 is set as a curved arc. By rotating the arc-shaped semi-ring plate 23, the low-manganese titanium slag can be better stirred compared with the vertical plate. The rotation of the rotating shaft 20 causes the multiple sets of support columns 21, ring body 22 and semi-ring plates 23 arranged on the rotating shaft 20 to rotate synchronously, thereby realizing the mixing of low-manganese titanium slag in the inner cavity of the storage tank 1, breaking the agglomeration of low-manganese titanium slag, ensuring that the low-manganese titanium slag is always in a flowable state, which helps to improve the continuity of discharge, so that the low-manganese titanium slag can flow out of the discharge port evenly, and reducing the interruption of discharge caused by local accumulation of low-manganese titanium slag.

[0032] A drive unit is provided at the top of the rotating shaft 20. The drive unit includes a second pulley 28 fixedly installed at the top of the rotating shaft 20, and a motor frame 24 fixedly installed on the right side wall of the storage tank 1. A second motor 25 is installed on the motor frame 24. The output end of the second motor 25 is connected to a drive shaft 26. A first pulley 27 is installed on the drive shaft 26. A belt 29 is fitted on the first pulley 27 and the second pulley 28. When the second motor 25 is turned on, it drives the drive shaft 26 and the first pulley 27 to rotate, so that the belt 29 drives the second pulley 28 to rotate, thereby realizing the rotation of the rotating shaft 20.

[0033] The top of the storage tank 1 is connected to the inlet 4, through which low manganese titanium slag can be fed into the storage tank 1 for subsequent processing.

[0034] It is worth noting that in this application, the controller 2 adopts a commonly used controller model on the market. It is a digital computing electronic system specifically designed for industrial applications. It uses a programmable memory to store instructions for performing logical operations, sequential control, timing, counting, and arithmetic operations. It controls various types of mechanical equipment or production processes through digital or analog input and output. The specific model of the controller 2 is not limited here. The first motor 13 and the second motor 25 are commonly used self-locking motors with lockable output terminals. When they stop, the output terminals can lock themselves and will not rotate under external force. The first motor 13 and the second motor 25 are commonly used forward and reverse motors on the market. Their output terminals can rotate in the forward or reverse direction according to the usage requirements. It is sufficient that they can meet the above usage requirements. The existing components mentioned above will not be described in detail here.

[0035] The working principle of the low-manganese titanium slag continuous discharge device in this embodiment is as follows:

[0036] The second motor 25 drives the drive shaft 26 and the first pulley 27 to rotate, which in turn causes the belt 29 to drive the second pulley 28 to rotate, thereby realizing the rotation of the rotating shaft 20. This causes the multiple sets of support pillars 21, rings 22 and semi-ring plates 23 on the rotating shaft 20 to rotate synchronously, thereby achieving the mixing of low-manganese titanium slag in the inner cavity of the storage tank 1, breaking up the clumps formed by the low-manganese titanium slag, ensuring that the low-manganese titanium slag is always in a flowable state, which helps to improve the continuity of discharge, so that the low-manganese titanium slag can flow out of the discharge port evenly, and reducing the interruption of discharge caused by local accumulation of low-manganese titanium slag.

[0037] After being processed inside the storage tank 1, the low-manganese titanium slag flows downward through the discharge port 5. During the flow of the low-manganese titanium slag, the impact force on the disc 8 varies depending on the output amount of low-manganese titanium slag. When the amount of low-manganese titanium slag discharged is large, the disc 8 is impacted more significantly, causing the swing rod 7, disc 8, and lever 9 to swing clockwise synchronously to a larger amplitude. This causes the lever 9 to sequentially activate multiple spring-loaded trigger 10s. The activated spring-loaded trigger 10s transmit signals to the controller 2 for processing. 2. The first motor 13 is turned on, which drives the lead screw 14 to rotate, causing the moving seat 16 to move to the right and downward along the lead screw 14 and the limit rod 15. This causes the connecting rod 17 to move downward at the rotational connection point with the moving seat 16, causing the cover 19 to open counterclockwise to a larger angle with the rotational connection point with the fixed seat 18 as the axis. Through the impact of the disc 8 by different amounts of low-manganese titanium slag, the lever 9 is activated to actuate different numbers of spring-loaded triggers 10, causing the cover 19 to open to different angles.

[0038] This invention automatically detects the discharge rate of low-manganese titanium slag as it falls along the discharge port 5. Based on the flow rate and accumulation of the low-manganese titanium slag, it automatically adjusts the opening and closing of the cover 19 to ensure continuous discharge. When the flow rate of the low-manganese titanium slag is high, the cover 19 automatically opens wider to avoid blockage. When the flow rate of the titanium slag is low, the cover 19 is appropriately closed to maintain stable discharge and reduce discontinuous discharge. It can also continuously stir the low-manganese titanium slag in the storage tank 1 and continuously push the low-manganese titanium slag towards the discharge port, while breaking up the clumps formed by the low-manganese titanium slag. This ensures that the low-manganese titanium slag is always in a flowable state, which helps to improve the continuity of discharge and allows the low-manganese titanium slag to flow out of the discharge port evenly, reducing the interruption of discharge caused by local accumulation of low-manganese titanium slag.

[0039] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
