Description

Technical Field

[0001] This invention relates to the field of mineral processing reagent production equipment, and in particular to a feeding structure for high-viscosity mineral processing reagent raw materials. Background Technology

[0002] In mineral processing, beneficiation reagents are key auxiliary materials for achieving efficient separation of valuable minerals from gangue. The accuracy and stability of their addition directly affect flotation performance and production costs. There are various types of beneficiation reagents, mainly including collectors, frothers, and modifiers. Different reagents, due to their varying physicochemical properties, place diverse demands on feeding equipment. Especially in the feeding of high-viscosity reagent feedstocks, such as certain oil-based collectors and polymer modifiers, the viscosity increases significantly and the fluidity decreases sharply at room temperature or low temperatures, sometimes even exhibiting semi-solid properties. Conventional gravity flow or mechanical feeding methods often fail to achieve stable and controllable transport, easily leading to problems such as blockages, flow interruptions, or metering deviations.

[0003] In mineral processing, beneficiation reagents are key auxiliary materials for achieving efficient separation of valuable minerals from gangue. The accuracy and stability of their addition directly affect flotation performance and production costs. There are various types of beneficiation reagents, mainly including collectors, frothers, and modifiers. Different reagents, due to their varying physicochemical properties, place diverse demands on feeding equipment. Especially in the feeding of high-viscosity reagent feedstocks, such as certain oil-based collectors and polymer modifiers, the viscosity increases significantly and the fluidity decreases sharply at room temperature or low temperatures, sometimes even exhibiting semi-solid properties. Conventional gravity flow or mechanical feeding methods often fail to achieve stable and controllable transport, easily leading to problems such as blockages, flow interruptions, or metering deviations.

[0004] Based on the above situation, there is an urgent need to develop a new type of feeding structure that can adapt to the characteristics of high-viscosity mineral processing reagents and has overload sensing and energy buffering functions, so as to improve feeding accuracy, system reliability and equipment adaptability, and meet the requirements of modern mineral processing reagent production processes for refinement and stability. Summary of the Invention

[0005] In order to overcome the shortcomings of existing high-viscosity mineral processing reagents, which are prone to motor overload, blockage and inaccurate metering due to excessive starting torque during the feeding process, this invention provides a feeding structure for high-viscosity mineral processing reagent raw materials.

[0006] A feeding structure for high-viscosity mineral processing reagent raw materials includes a base, a rotating frame rotatably connected to the base, a feed frame inside the rotating frame, a feed hopper and a discharge port on the feed frame, an auger rotatably connected inside the feed frame, a rotating ring fixed to the end of the auger, a motor mounted on the rotating frame, a push ring keyed to its output shaft, symmetrically distributed paddles on the sides of the rotating ring and the push ring that are close to each other, the rotating ring and the push ring abut against each other to achieve power transmission, and a switching component for compensating for the torsion of the auger on the rotating frame.

[0007] In one embodiment, the switching assembly includes a fixed frame fixed to a rotating frame, a housing fixed to the fixed frame, a rotating shaft rotatably connected to the fixed frame, a one-way gear and a third gear fixed to both ends of the rotating shaft, a spring connecting the rotating shaft and the inner wall of the housing, a first gear fixed to the side of the auger near the one-way gear, the first gear meshing with the one-way gear, a second gear fixed to the push ring, the second gear meshing with the third gear, thus forming a gear transmission system.

[0008] In one embodiment, a cylinder is mounted on the rotating frame, and a connecting frame is fixedly connected to the telescopic part of the cylinder. The connecting frame is rotatably connected to the push ring.

[0009] In one embodiment, a torque sensor is provided on the output shaft of the motor, and the torque sensor is electrically connected to the cylinder through a control module.

[0010] In one embodiment, a screw is rotatably connected to the base, and a sliding frame is threadedly connected to the screw. The sliding frame slides horizontally on the base, and symmetrically distributed connecting rods are provided between the sliding frame and the rotating frame.

[0011] In one embodiment, the end of the screw is provided with a handle that increases the lever arm.

[0012] In one embodiment, the outlet of the feed frame is cone-shaped.

[0013] Beneficial effects: This feeding structure effectively copes with load fluctuations of high-viscosity materials by integrating torque sensing and intelligent switching mechanism. When the material viscosity is too high and the motor torque exceeds the limit, the system can automatically cut off the main drive path and switch the power to the spring energy storage system. After the spring stores energy to the rated torque, the main drive quickly resets and is superimposed with the additional torque released by the spring to jointly drive the auger. This design not only avoids the risk of motor stalling, but also significantly enhances the system's instantaneous overload capacity, ensuring the continuous and stable forced delivery of high-viscosity agents under harsh working conditions.

[0014] This feeding structure features flexible attitude adjustment, allowing for easy adjustment of the overall machine tilt angle via a screw mechanism. It utilizes the material's own weight to assist in discharge, effectively reducing conveying resistance. Combined with a conical discharge port design, it further enhances the discharge efficiency of high-viscosity materials and prevents blockages. The overall structure achieves full-process optimization from power adaptation to discharge attitude, significantly improving the reliability, adaptability, and production efficiency of the feeding process.

Detailed Implementation

[0022] The invention will now be described more fully below with reference to the accompanying drawings, in which presently preferred embodiments of the invention are illustrated. However, the invention may be embodied in many different forms and should not be construed as limited to the embodiments set forth herein; rather, these embodiments are provided for thoroughness and completeness and to fully convey the scope of the invention to those skilled in the art.

[0023] Example 1: A feeding structure for high-viscosity mineral processing reagent raw materials, such as... Figure 1 and Figure 2As shown, the device includes a base 101 as the main support, a rotating frame 102 rotatably connected to the base 101 for angle adjustment to adapt to different feeding scenarios; a feeding frame 103 is provided inside the rotating frame 102 as a channel for material storage and conveying; a feeding hopper is provided on the feeding frame 103 for material input; a cone-shaped discharge port is provided on the side away from the feeding hopper, which increases the pressure when the material is discharged by reducing the cross-sectional area of ​​the outlet, so that high-viscosity materials can be extruded smoothly and the discharge port can be prevented from being blocked; an auger 104 is rotatably connected inside the feeding frame 103, which pushes the material through the rotation of the spiral blades to achieve forced conveying of high-viscosity materials.

[0024] A rotating ring 105 is fixedly connected to the end of the auger 104. A motor 107 is mounted on the rotating frame 102 as a power output source. A push ring 106 is keyed to its output shaft. The push ring 106 has only horizontal movement freedom on the output shaft of the motor 107, but no rotational freedom, ensuring stable power transmission while allowing axial position adjustment. Symmetrically distributed paddles are provided on the sides of the rotating ring 105 and the push ring 106 that are close to each other. The rotating ring 105 and the push ring 106 are abutted by the paddles to achieve power transmission. The rotating frame 102 is provided with a switching component for compensating the torsion of the auger 104 to cope with torque fluctuations caused by changes in material viscosity.

[0025] like Figure 2 and Figure 3 As shown, specifically, the switching assembly includes a fixed frame 108 fixed to the rotating frame 102, serving as the mounting base for the assembly; a housing 113 is fixed to the fixed frame 108, serving to protect and house the internal components; a rotating shaft 110 is rotatably connected to the fixed frame 108 for transmitting torque and storing elastic potential energy; a one-way gear 109 and a third gear 111 are fixed to the two ends of the rotating shaft 110, respectively, with the one-way gear 109 enabling unidirectional power transmission and the third gear 111 used for gear meshing transmission; the rotating shaft 110 and the housing 113... A spring 112 is connected between the inner walls of 13, which stores and releases energy through elastic deformation to provide torsional compensation for the auger 104; a first gear 1071 is fixedly connected to the side of the auger 104 near the one-way gear 109, and the first gear 1071 meshes with the one-way gear 109. A second gear 1072 is fixedly connected to the push ring 106. When the second gear 1072 moves to the right with the push ring 106, the second gear 1072 will mesh with the third gear 111 to form a gear transmission system and realize the switching of the power transmission path.

[0026] like Figure 4As shown, specifically, a cylinder 202 is mounted on the rotating frame 102 as a linear drive device; a connecting frame 201 is fixedly connected to the telescopic part of the cylinder 202 for connecting the cylinder 202 and the push ring 106; the connecting frame 201 and the push ring 106 are rotatably connected to ensure that the rotation of the push ring 106 is not interfered with; a torque sensor 203 is provided on the output shaft of the motor 107 for real-time detection of the torque of the output shaft of the motor 107 and sensing load changes. The torque sensor 203 and the cylinder 202 are electrically connected through a control module to form a closed-loop control, realizing precise control of the actuator by the torque signal.

[0027] When the material becomes more viscous in a low-temperature environment, the starting torque of the motor 107 increases. When the torque sensor 203 detects the increase in the torque of the motor 107, the torque sensor 203 will control the cylinder 202 to drive the connecting frame 201 to move to the right. The connecting frame 201 will drive the push ring 106 to move to the right, so that the push ring 106 disengages from the paddle of the rotating ring 105. At the same time, the second gear 1072 meshes with the third gear 111. At this time, the power of the motor 107 drives the rotating shaft 110 to rotate through the gear transmission and tightens the spring 112 to store energy.

[0028] The operating process of this high-viscosity mineral processing reagent feed structure is as follows: When this feeding structure is in operation, the high-viscosity mineral processing reagent raw material is first fed into the feed frame 103 through the feed hopper. The motor 107 is started through the control system, and its output shaft drives the push ring 106 and the second gear 1072 to rotate synchronously. Since the push ring 106 and the rotating ring 105 are interlocked, the power is transmitted to the first gear 1071 and the auger 104 through the rotating ring 105. The auger 104, through the forced pushing action of the spiral blades, conveys the material in the feed frame 103 towards the discharge port, and finally discharges it to the next process through the conical discharge port.

[0029] During the feeding process, the torque sensor 203 monitors the torque value of the output shaft of the motor 107 in real time. When the viscosity of the material increases (such as in a low-temperature environment) and the load torque exceeds the set threshold, the control module triggers the cylinder 202 to act. The telescopic part of the cylinder 202 pushes the connecting frame 201 to drive the push ring 106 to move to the right along the output shaft of the motor 107, so that the push ring 106 disengages from the toggle block of the rotating ring 105, cutting off the direct power transmission. At the same time, the second gear 1072 meshes with the third gear 111.

[0030] At this time, the motor 107 drives the shaft 110 to rotate via gear transmission, causing the spring 112 to elastically deform and store potential energy. When the spring 112 reaches its maximum energy storage state, the cylinder 202 reverses its action, causing the push ring 106 to reset, the shift block to re-engage and resume power transmission, and at the same time, the second gear 1072 disengages from the third gear 111. The elastic potential energy released by the spring 112 drives the shaft 110 to rotate in the opposite direction, and through the meshing transmission of the one-way gear 109 and the first gear 1071, outputs compensating torque to the auger 104 to ensure that its total torque meets the requirements for conveying high-viscosity materials.

[0031] Example 2: Figure 5 and Figure 6 As shown, specifically, a screw 301 is rotatably connected to the base 101 as a transmission component; a sliding frame 302 is threadedly connected to the screw 301, and the sliding frame 302 slides horizontally on the base 101. Symmetrically distributed connecting rods 303 are provided between the sliding frame 302 and the rotating frame 102 to transmit force to drive the rotating frame 102 to rotate.

[0032] When the screw 301 rotates, it can drive the sliding frame 302 to move horizontally. The sliding frame 302 will push the rotating frame 102 upward or pull it downward through the connecting rod 303, so that the rotating frame 102 is tilted up with the left side lower and the right side higher or is in a horizontal state. The tilted state can make the material in the feed frame 103 flow out more easily under the action of gravity, assisting in the conveying of high viscosity materials and reducing the conveying resistance.

[0033] The end of the screw 301 is provided with a handle 304. By increasing the lever arm, it is easier to rotate the screw 301 and make it easier to manually adjust the angle of the rotating frame 102.

[0034] To optimize the feeding effect of high-viscosity materials into the target container, the tilt angle of the rotating frame 102 can be adjusted. During operation, rotating the handle 304 drives the screw 301 to rotate, causing the sliding frame 302 to move horizontally. For example, rotating the handle 304 counterclockwise moves the sliding frame 302 to the right, lifting the right end of the rotating frame 102 via the connecting rod 303, resulting in a left-low, right-high tilt, with the discharge port of the feed frame 103 at a lower position, facilitating material discharge under gravity. Rotating the handle 304 clockwise moves the sliding frame 302 to the left, pulling down the right end of the rotating frame 102 via the connecting rod 303, restoring it to a horizontal position. By adjusting the tilt angle, the discharge posture can be effectively controlled to adapt to different feeding requirements.

[0035] The above description is merely a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in the present invention should be included within the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be determined by the scope of the claims.
