Description

Technical Field

[0001] This invention relates to the field of quantitative addition of mineral processing reagents, and more particularly to a device for quantitative addition of mineral processing reagents. Background Technology

[0002] In mineral processing, beneficiation reagents are crucial for improving mineral separation efficiency, especially in flotation. Flotation relies on reagents such as collectors, frothers, and modifiers acting on the mineral surface to effectively separate the target mineral from gangue. Furthermore, beneficiation reagents also play an auxiliary role in improving separation efficiency in gravity separation, magnetic separation, electrostatic separation, and even leaching processes. Therefore, the precision and effectiveness of reagent addition directly affect beneficiation indicators, production costs, and resource utilization.

[0003] It is worth noting that a significant portion of mineral processing agents (such as certain collectors and depressants) exist in solid form. Before use, these solid reagents must be dissolved in water to prepare solutions of a specified concentration so that they can be accurately added to the slurry. However, existing reagent dissolution and addition devices have significant shortcomings: they typically use a simple stirring rod for solid-liquid mixing. This method is inefficient, and it is particularly prone to causing denser solid reagent particles to settle at the bottom of the container, failing to fully contact and dissolve with water. Insufficient dissolution directly leads to uneven reagent solution concentration, which in turn results in a loss of precision in the subsequent quantitative addition of reagents to the slurry. This problem of insufficient dissolution and low mixing efficiency not only reduces the actual effectiveness of mineral processing reagents, affecting the recovery rate of target minerals and concentrate grade, but may also lead to reagent waste, increased production costs, and failure to meet the stringent requirements of modern mineral processing technology for efficient, precise, stable, and environmentally friendly operation.

[0004] Based on the above situation, there is an urgent need to develop a new type of solid mineral processing reagent quantitative addition device that can effectively solve the core problems of incomplete dissolution and uneven mixing of solid reagents in the existing technology, and ensure that the reagents are added to the slurry at a precise concentration and in a uniform state, thereby improving the overall efficiency and economic benefits of mineral processing. Summary of the Invention

[0005] To overcome the shortcomings of traditional stirring rod mixing methods, which cause solid reagents to settle at the bottom of the container, resulting in incomplete dissolution, uneven reagent concentration, and inaccurate quantitative addition, this invention provides a mineral processing reagent quantitative addition device.

[0012] In a preferred embodiment of the present invention, a plurality of guide blocks are equally spaced along the circumference of the inner surface of the mounting frame, and each guide block is provided with symmetrically distributed inclined surfaces.

Detailed Implementation

[0023] Although the invention may be described with respect to specific applications or industries, those skilled in the art will recognize its broader applicability. Those skilled in the art will understand that terms such as "above," "below," "upward," "downward," etc., are used to describe the drawings and not to indicate a limitation on the scope of the invention as defined by the appended claims. Any numerical designations such as "first" or "second" are merely illustrative and not intended to limit the scope of the invention in any way.

[0024] Example 1: A device for quantitatively adding mineral processing reagents, such as... Figures 1-4 As shown, the device includes an arc-shaped mounting frame 101 for securing the entire device to the container. A sliding frame 102 is slidably connected to the mounting frame 101 so that it can move around the container, thereby ensuring that the mineral processing agent can be added to the container evenly and comprehensively. A liquid storage cylinder 103 is fixedly connected to the top of the sliding frame 102. The top of the liquid storage cylinder 103 is provided with a feed pipe for conveniently adding the mineral processing agent and water into the liquid storage cylinder 103 for mixing. A water pump 104 is installed on the sliding frame 102. The water pump 104 is located directly below the liquid storage cylinder 103. The water inlet of the water pump 104 is fixedly connected to the bottom wall of the liquid storage cylinder 103 for drawing liquid from the liquid storage cylinder 103.

[0025] A drain pipe 1061 is fixedly connected to the outlet of the water pump 104. The outlet of the drain pipe 1061 faces the container to accurately introduce the mixed mineral processing agent solution into the container. A first solenoid valve 105 is installed on the drain pipe 1061 to control the opening and closing of the drain pipe 1061, thereby precisely adjusting the discharge amount of the mineral processing agent. A return pipe 106 is connected between the return port of the water pump 104 and the storage tank 103. A second solenoid valve 107 is installed at the inlet of the return pipe 106 to control whether the liquid flows back into the storage tank 103, so as to maintain liquid circulation during the mixing stage. A stirring frame 109 is rotatably connected to the top wall of the storage tank 103. A certain distance is left between the bottom of the stirring frame 109 and the inner bottom wall of the storage tank 103 to avoid wear on the bottom of the storage tank 103 during the stirring process and to ensure that the liquid can flow fully.

[0026] An impeller 108 is fixedly connected to the stirring frame 109, which is used to drive the stirring frame 109 to rotate by the impact force of the liquid, thereby achieving full stirring of the liquid in the storage tank 103. The outlet of the return pipe 106 is flush with the impeller 108 to ensure that the return liquid can directly act on the impeller 108, thereby improving the stirring efficiency. The outlet of the return pipe 106 is arc-shaped and fits against the inner wall of the storage tank 103, so that the liquid flowing out of the outlet of the return pipe 106 can more smoothly wash onto the blades of the impeller 108, further enhancing the ability of the impeller 108 to drive the stirring frame 109 to rotate, thereby achieving a more uniform mixing effect.

[0027] like Figure 3 and Figure 4 As shown, symmetrically distributed stirring blades 201 are fixed to the stirring frame 109 for omnidirectional agitation of the liquid during the stirring process, thereby improving mixing efficiency and uniformity. The stirring blades 201 are inclined, so that the longitudinal stirring blades 201 can form a louver-like state, so that when the stirring frame 109 rotates, the inclined angle will turn the liquid at the bottom upward, thereby promoting the vertical circulation of the liquid in the liquid storage cylinder 103, and ultimately achieving a more uniform mixing effect.

[0028] like Figure 5 and Figure 6 As shown, a motor 301 is provided on the sliding frame 102 to drive the movement and operation of the entire device. The output shaft of the motor 301 is fixedly connected to a gear 302 through a coupling. An arc-shaped rack 303 is provided on the outer side of the mounting frame 101. The gear 302 and the arc-shaped rack 303 mesh in an arc shape to form a gear 302 transmission system, so that the motor 301 can drive the gear 302 to rotate, thereby realizing the stable sliding of the sliding frame 102 along the mounting frame 101 and ensuring that the device can move evenly around the container.

[0029] In use, first fix the mounting bracket 101 to the top of the container, and then add the mineral processing agent and an appropriate amount of water through the feed pipe at the top of the storage cylinder 103. Temporarily close the first solenoid valve 105, and simultaneously open the second solenoid valve 107 to start the water pump 104.

[0030] Pump 104 draws liquid from storage tank 103 and returns it to storage tank 103 through return pipe 106. The returning liquid impacts the blades of impeller 108, driving impeller 108 to rotate, which in turn drives stirring frame 109 and its inclined stirring blades 201 to rotate synchronously. The inclined design of stirring blades 201 can effectively agitate the liquid in the lower part of storage tank 103, preventing the mineral processing agent from settling and ensuring that the liquid is fully and uniformly mixed.

[0031] Once the liquid mixture is fully and evenly mixed, the first solenoid valve 105 is opened, and the mixed liquid is discharged through the drain pipe 1061 to the nozzle 405, and then evenly introduced into the container through the nozzle 405. To improve the uniformity of the distribution, the motor 301 drives the gear 302 to rotate. The gear 302 meshes with the arc-shaped rack 303, pushing the sliding frame 102 to reciprocate along the mounting frame 101, thereby achieving uniform distribution of the liquid storage cylinder 103 around the container.

[0032] Example 2: Figure 6 and Figure 7 As shown, a plurality of guide blocks 401 are evenly spaced along the circumference of the inner surface of the mounting frame 101. Each guide block 401 has symmetrically distributed inclined surfaces. The outlet of the drain pipe 1061 is connected to the nozzle 405 through a corrugated pipe 406. The design of the corrugated pipe 406 allows the nozzle 405 to move freely within a certain range, thereby adapting to the needs of different positions. The inner surface of the sliding frame 102 is fixed with symmetrically distributed fixing blocks 402. Sliding blocks 403 are slidably connected between the symmetrically distributed fixing blocks 402. A connecting rod 404 is rotatably connected to the sliding block 403 to realize the flexible adjustment of the nozzle 405 in different positions. The nozzle 405 is rotatably connected to the connecting rod 404 so that the nozzle 405 can always maintain the optimal distance from the inner wall of the container during the movement of the sliding frame 102, thereby achieving uniform spraying of the mineral processing agent.

[0033] like Figure 7 As shown, the bottom of the slider 403 is arc-shaped to fit tightly with the inclined surface of the guide block 401. When the sliding frame 102 moves along the mounting frame 101, the slider 403 will automatically slide up and down according to the inclined shape of the guide block 401, thereby driving the connecting rod 404 to move synchronously, so as to realize the height adjustment of the nozzle 405.

[0034] During the movement of the sliding frame 102, the slider 403 contacts and slides along the inclined surface of the guide block 401. When the slider 403 moves to the top plane of the guide block 401, it is lifted by the inclined surface of the guide block 401, causing the nozzle 405 to tilt upwards via the connecting rod 404, and the bellows 406 to stretch accordingly. At this time, the outlet of the nozzle 405 faces upwards, and the liquid is sprayed into the container in a parabolic shape, significantly increasing the spreading range and uniformity.

[0035] As slider 403 continues to move to the other inclined surface of guide block 401, it returns to its original position under its own gravity, via a connection such as... Figure 1-7 As shown, rod 404 drives nozzle 405 to return to a horizontal state, and bellows 406 also retracts to its original length.

[0036] As the sliding frame 102 continues to move back and forth, the slider 403 continuously contacts and separates from multiple guide blocks 401, causing the nozzle 405 to switch between horizontal and tilted states, thereby achieving a wider and more uniform distribution of the material.

[0037] Finally, it should be noted that the above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
