Abstract
Description
Technical Field
[0001] This utility model relates to the field of ore classification and discharge technology, and in particular to a discharge device for an antimony oxide ore classifier. Background Technology
[0002] The discharge device of an antimony oxide ore classifier, as a crucial part of the antimony ore beneficiation process, plays a vital role in smoothly discharging the classified ore, directly impacting the efficiency and quality of the entire beneficiation production. In the antimony ore beneficiation industry, the discharge stage of the classifier is widely used in the processing of various antimony oxide ores, separating ores of different particle sizes to provide suitable raw materials for subsequent processing steps. In practical applications, the discharge device of an antimony oxide ore classifier typically includes the following components:
[0003] 1. Spiral discharge mechanism: The rotation of the spiral blades drives the ore to move, realizing the discharge process, and has the characteristics of continuous and stable discharge;
[0004] 2. Discharge port components: As the channel for ore discharge, their structure and size play a key role in controlling the discharge speed and particle size.
[0005] 3. Drive unit: Provides power to the screw conveyor mechanism to ensure its normal operation. Common types include motor drive, with a speed reducer to adjust the speed.
[0006] 4. Support structure: It plays a role in fixing and supporting the entire discharge device, ensuring its stability during operation.
[0007] Currently, various equipment and methods have been adopted in the industry to improve the performance of the discharge device of antimony oxide ore classifiers. Some manufacturers have improved the discharge efficiency by optimizing the blade shape of the spiral discharge mechanism; others have improved the material of the discharge port to enhance its wear resistance; and still others have introduced intelligent control systems into the drive unit to achieve precise control of the discharge speed.
[0008] However, the above-described implementation still has the following problems. When dealing with antimony oxide ores of different properties, the discharge device lacks adaptability. On the one hand, the existing spiral discharge devices mostly have a fixed inclination angle, making it difficult to adjust according to the particle size, moisture content, density, and other characteristics of the ore. This leads to problems such as material blockage and poor classification during the discharge process. On the other hand, the discharge port size is usually not adjustable, failing to meet the diverse requirements of different production processes for discharge particle size and flow rate, resulting in low production efficiency and unstable product quality. This application proposes a solution to this problem: designing a discharge device for an antimony oxide ore classifier where both the spiral discharge device's inclination angle and discharge port size are adjustable. This device can be flexibly adjusted according to the ore properties and production requirements, effectively improving discharge efficiency and classification quality, reducing equipment failure rate, and increasing the overall economic benefits of mineral processing. Utility Model Content
[0009] To address the shortcomings of existing technologies, this utility model provides a discharge device for an antimony oxide ore classifier. It solves the problem that the tilt angle of existing spiral discharge devices is mostly fixed, making it difficult to adjust according to the particle size, moisture content, density, and other characteristics of the ore. This leads to problems such as material blockage and poor classification effect during the discharge process. On the other hand, the size of the discharge port is usually not adjustable, which cannot meet the diverse needs of different production processes for discharge particle size and flow rate, resulting in low production efficiency.
[0010] To achieve the above objectives, this utility model provides the following technical solution:
[0011] A discharge device for an antimony oxide ore classifier includes a base plate and a classification trough. A servo motor is fixedly installed on the right surface of the classification trough. A classification mechanism is provided inside the classification trough. A baffle is movably connected to the inner wall of the classification trough. A connecting block is fixedly connected to the front surface of the baffle. A limiting block for limiting is movably connected inside the connecting block. A return spring is fixedly connected to the front surface of the limiting block. A push block is provided above the base plate. A slider for limiting is fixedly connected to the lower surface of the push block. The output shaft of the servo motor is fixedly connected to the classification mechanism. A limiting groove is formed on the upper surface of the base plate. The limiting groove is movably connected to the slider.
[0012] Preferably, a cylinder is fixedly installed on the upper surface of the base plate, the piston of the cylinder is fixedly connected to the push block, and a set of slots is opened on the front surface of the grading groove, and each set of slots is movably engaged with the limiting block.
[0013] Preferably, the rear surface of the connecting block has a second slot, the second slot is movably engaged with the limiting block, the reset spring is fixedly connected to the second slot, and a pull rod is fixedly connected to the front surface of the limiting block.
[0014] Compared with the prior art, the present invention has the following beneficial effects:
[0015] 1. During use, the material is fed into the grading tank. The servo motor is started to drive the grading mechanism to rotate, achieving spiral grading. During the grading process, the piston of the cylinder is started to drive the fixed pusher block to move. The pusher block is stabilized during the movement by a fixed slider. The movement of the pusher block will push the grading tank to rotate. The angle can be adjusted by rotating the left end of the grading tank. A suitable tilt angle helps to form a more stable slurry flow field in the classifier. When the tilt angle of the spiral discharge device matches the slurry flow state in the classifier, coarse particles can move more accurately to the discharge port, while fine particles are more easily discharged in the overflow, thereby reducing the mixing of coarse and fine particles and improving the accuracy and efficiency of grading.
[0016] 2. During the discharge process, pulling the lever moves the fixed limit block, compressing the return spring. The movement of the limit block disengages it from the set of slots on the grading tank, opening the limit. At this point, the baffle can be moved to adjust the size of the discharge port. Different batches of antimony oxide ore may differ in particle size, hardness, moisture content, and other properties. Adjustable discharge port size allows the classifier to better adapt to these changes. For ores with larger particle size and higher hardness, appropriately increasing the discharge port can prevent discharge blockage and ensure normal operation of the device. For ores with higher moisture content and stronger viscosity, a smaller discharge port can prevent excessive agglomeration of materials during discharge, which is conducive to achieving finer grading.

This device can be flexibly adjusted according to the ore properties and production requirements, effectively improving discharge efficiency and classification quality, reducing equipment failure rate, and improving the economic benefits of the entire mineral processing production.
[0024] Example
[0025] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the technical solution in this application effectively solves the problems of existing spiral discharge devices having mostly fixed inclination angles, making it difficult to adjust them according to the particle size, moisture content, density, and other characteristics of the ore. This leads to problems such as material blockage and poor grading during the discharge process. On the other hand, the discharge port size is usually not adjustable, which cannot meet the diverse requirements of different production processes for discharge particle size and flow rate, resulting in low production efficiency. The overall approach is as follows:
[0026] To address the problems existing in the prior art, this utility model provides a discharge device for an antimony oxide ore classifier, including a base plate 1 and a classification tank 2. A servo motor 3 is fixedly installed on the right surface of the classification tank 2. A classification mechanism 4 is provided inside the classification tank 2. A baffle 5 is movably connected to the inner wall of the classification tank 2. A connecting block 9 is fixedly connected to the front surface of the baffle 5. A limiting block 12 for limiting is movably connected inside the connecting block 9. A return spring 14 is fixedly connected to the front surface of the limiting block 12. A push block 7 is provided above the base plate 1. A slider 10 for limiting is fixedly connected to the lower surface of the push block 7. The output shaft of the servo motor 3 is fixedly connected to the classification mechanism 4. A limiting groove 11 is formed on the upper surface of the base plate 1. The limiting groove 11 is movably connected to the slider 10. During use, the material is discharged... The material is placed in the grading tank 2, and the servo motor 3 drives the grading mechanism 4 to rotate to achieve spiral grading. During the grading process, the piston of the cylinder 8 is activated, which drives the fixed push block 7 to move. The push block 7 is stabilized during the movement by the fixed slider 10. The movement of the push block 7 will push the fitted grading tank 2 to rotate. The left end of the grading tank 2 can be rotated to adjust its angle. A suitable tilt angle helps to form a more stable slurry flow field in the classifier. When the tilt angle of the spiral discharge device matches the slurry flow state in the classifier, coarse particles can move more accurately to the discharge port, while fine particles are more easily discharged in the overflow, thereby reducing the mixing of coarse and fine particles and improving the accuracy and efficiency of grading.
[0027] A cylinder 8 is fixedly installed on the upper surface of the base plate 1. The piston of the cylinder 8 is fixedly connected to the push block 7. A set of slots 6 is opened on the front surface of the grading tank 2. Each set of slots 6 is movably engaged with the limit block 12. A slot 15 is opened on the rear surface of the connecting block 9. The slot 15 is movably engaged with the limit block 12. The return spring 14 is fixedly connected to the slot 15. A pull rod 13 is fixedly connected to the front surface of the limit block 12. During the discharge process, pulling the pull rod 13 moves the fixed limit block 12 together, compressing the return spring 14. The movement of the limit block 12 will disengage it from the grading tank 2. A set of slots 6 on the upper part of the machine engages and opens the limit switch. At this time, the baffle 5 can be moved to adjust the size of the discharge port. Different batches of antimony oxide ore may have differences in particle size, hardness, moisture content, and other properties. Adjustable discharge port size allows the classifier to better adapt to these changes. For ores with larger particle size and higher hardness, appropriately increasing the discharge port can avoid discharge blockage and ensure normal operation of the device. For ores with higher moisture content and stronger viscosity, a smaller discharge port can prevent excessive agglomeration of materials during the discharge process, which is conducive to achieving finer classification.
[0028] Among them, the base plate 1 is the supporting foundation of the entire discharge device, provides installation positions for other components, and cooperates with the slider 10 through the limiting groove 11 to ensure the stable movement of the push block 7;
[0029] Classification tank 2: Used to hold materials and perform classification operations. Its angle is adjustable, which can optimize the slurry flow field and improve classification accuracy and efficiency. It is also equipped with a slot 6 and other structures.
[0030] Servo motor 3: provides power to the classification mechanism 4, drives the classification mechanism 4 to rotate, and realizes the spiral classification operation of antimony oxide ore;
[0031] Grading mechanism 4: Driven by servo motor 3, it rotates to spiral grade the antimony oxide ore fed into grading tank 2, and is the core component for achieving grading.
[0032] Baffle 5: It can be moved to adjust the size of the discharge port to adapt to the discharge requirements of different types of ore, avoid blockage and excessive agglomeration, and ensure the discharge effect;
[0033] Slot 16: It is movably engaged with limit block 12, which limits the angle adjustment of grading groove 2 and ensures that grading groove 2 works stably at a suitable angle;
[0034] Push block 7: Moves under the drive of cylinder 8, pushes the grading tank 2 to rotate, realizes the adjustment of the tilt angle of the grading tank 2, and ensures that the grading process is more efficient;
[0035] Cylinder 8: Drives the pusher block 7 through piston movement, providing power for the angle adjustment of the grading groove 2, and is the driving component for realizing the angle adjustment of the grading groove 2;
[0036] Connecting block 9: connects the baffle 5 and the limiting block 12. The second slot 15 on it cooperates with the limiting block 12 and also provides a fixed position for the return spring 14.
[0037] Slider 10: Fixed to the lower surface of push block 7, and movably connected to the limiting groove 11 on the base plate 1 to ensure that push block 7 remains stable during movement;
[0038] Limiting groove 11: It is formed on the base plate 1 and cooperates with the slider 10 to limit the movement trajectory of the push block 7, so that the push block 7 can smoothly push the grading groove 2 to rotate.
[0039] Limiting block 12: It is movably engaged with slot 1 6 and slot 2 15, and through cooperation with the return spring 14, it limits the angle of the grading groove 2 and the position of the baffle 5.
[0040] Pull rod 13: It is fixedly connected to the limit block 12. Pulling the pull rod 13 can drive the limit block 12 to move, so as to easily adjust the position of the baffle 5 to change the size of the discharge port;
[0041] Reset spring 14: One end is fixed in the second slot 15, providing a reset force for the limit block 12, so that the limit block 12 can automatically return to its original position and maintain the limit on the baffle 5 and the graded groove 2;
[0042] Slot 2 15: It is formed on the rear surface of the connecting block 9 and is movably engaged with the limiting block 12 to fix the reset spring 14 and assist in realizing the limiting function of the baffle 5.
[0043] Working principle:
[0044] During operation, materials are fed into the grading tank 2. The servo motor 3 drives the grading mechanism 4 to rotate, achieving spiral grading. During grading, the piston of the cylinder 8 moves a fixed pusher block 7. The pusher block 7 is stabilized by a fixed slider 10. The movement of the pusher block 7 pushes the fitted grading tank 2 to rotate. Rotating the left end of the grading tank 2 adjusts its angle. A suitable tilt angle helps create a more stable slurry flow field within the classifier. When the tilt angle of the spiral discharge device matches the slurry flow state within the classifier, coarse particles move more accurately towards the discharge port, while fine particles are more easily discharged in the overflow, thus reducing the mixing of coarse and fine particles and improving grading efficiency. To improve accuracy and efficiency, during the discharge process, pulling the lever 13 moves the fixed limit block 12, compressing the return spring 14. The movement of the limit block 12 disengages from the set of slots 6 on the grading tank 2, opening the limit. At this point, the baffle 5 can be moved to adjust the size of the discharge port. Different batches of antimony oxide ore may have differences in particle size, hardness, moisture content, etc. Adjustable discharge port size allows the classifier to better adapt to these changes. For ores with larger particle size and higher hardness, appropriately increasing the discharge port can prevent discharge blockage and ensure normal operation of the device. For ores with higher moisture content and stronger viscosity, a smaller discharge port can prevent excessive agglomeration of materials during the discharge process, which is conducive to achieving finer grading.
[0045] Finally, it should be noted that the above embodiments are merely examples for clearly illustrating the present invention and are not intended to limit the implementation. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
