Description

Technical Field

[0001] This utility model relates to the field of mineral processing equipment technology, and in particular to a high-efficiency mineral slurry thickener. Background Technology

[0002] Slurry thickeners are key pieces of equipment widely used in mining, metallurgy, and chemical industries. They are mainly used for solid-liquid separation operations, increasing the concentration of solid particles in the slurry through gravity settling. A typical slurry thickener usually consists of a large thickening pan and an agitator rake inside the pan, driven by a central drive shaft. The slow agitation of the rake promotes the settling of solid particles.

[0003] In actual operation, especially when processing slurries with high concentration, high viscosity, or large volume, the agitator rake is subjected to enormous and uneven material resistance. This continuous load acts on the slender drive shaft and the bulky rake frame structure, which over time can easily lead to drive shaft vibration, structural deformation of the agitator rake, or even damage. Once the stability of these core moving parts decreases, it will not only seriously affect the mixing and scraping effect and reduce the concentration efficiency, but also shorten the service life of the equipment and increase the risk and cost of downtime maintenance.

[0004] Meanwhile, some fine particles in the slurry have strong adhesive properties and easily adhere to the inner wall of the thickening pan during the thickening process, accumulating over time to form a hard scale. This scale not only continuously occupies the effective volume of the thickening pan, reducing the equipment's processing capacity, but also creates "dead zones," affecting the normal flow and settling of materials within the pan, thus significantly restricting the overall efficiency of the thickening operation. Therefore, how to effectively prevent material from sticking to the wall while ensuring the stability and reliability of the equipment structure is a key technical issue for improving the working efficiency and stability of the slurry thickener. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a high-efficiency slurry thickener, which aims to improve the problems of poor equipment stability caused by the easy deformation of core moving parts such as the stirring rake under stress, and the slurry easily adhering to the inner wall of the thickening pan, thus affecting the thickening efficiency. This utility model aims to provide a high-efficiency slurry thickener with an improved structure that can effectively solve the above problems.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a high-efficiency slurry thickener, comprising: a thickening plate, a support, a stirring rake, a motor, and a drive shaft; it also includes a reinforcing component and a wall scraping mechanism.

[0007] The reinforcement component is fixedly disposed on the outside of the drive shaft, providing radial support for the rotation of the drive shaft.

[0008] Furthermore, the wall scraping mechanism is fixedly connected to the drive shaft and rotates synchronously with the drive shaft. The inner wall scraper of the wall scraping mechanism is driven to closely adhere to the inner wall of the concentration tray when the wall scraping mechanism rotates.

[0009] Preferably, the reinforcement component includes a connecting column, a reinforcement column, and a reinforcement beam. The connecting column is used to strengthen the connection between the reinforcement component and the stirring rake. The reinforcement column and the reinforcement beam are connected at their ends to each other and are configured with the stirring rake to support a triangular stable structure.

[0010] Preferably, the reinforcement assembly further includes a reinforcement ring and a reinforcement rod. The reinforcement ring is coaxially disposed outside the transmission shaft, and one end of the reinforcement rod is connected to the reinforcement ring, while the other end is connected to the wall scraping mechanism.

[0011] Preferably, the wall scraping mechanism includes a column fixed to the drive shaft, and the inner wall scraper is fixedly connected to the column through a linkage mechanism.

[0012] Preferably, the linkage mechanism includes an arc rod and a connecting rod, one end of the arc rod is connected to the column, one end of the connecting rod is connected to the outside of the connecting block, and the other end of the connecting rod is connected to the inner wall scraper.

[0013] Preferably, the linkage mechanism further includes a connecting block and a central connecting shaft. The connecting block is used to fix the connecting rod to the outside of the stirring rake, and the central connecting shaft passes through the column.

[0014] Preferably, the high-efficiency slurry thickener further includes a receiving tank and a discharge pipe; the receiving tank is located at the bottom center of the thickening pan, and the discharge pipe is connected to the receiving tank.

[0015] Preferably, the high-efficiency slurry thickener further includes a frame, the motor is mounted and fixed on the frame, and the frame is fixed on the support.

[0016] This utility model has the following beneficial effects:

[0017] 1. In this utility model, by setting a triangular stabilizing structure composed of a connecting column, a reinforcing column and a reinforcing beam, and a reinforcing component consisting of a reinforcing ring and a reinforcing rod, the problem of structural deformation and unstable operation of the stirring rake and drive shaft in the existing thickener due to the large stirring resistance is solved.

[0018] 2. This utility model solves the problem of slurry easily adhering to the inner wall of the thickening pan and forming accumulations, thereby reducing the effective volume and thickening efficiency, by setting up a scraping mechanism that rotates synchronously with the transmission shaft and can make the inner wall scraper closely adhere to the inner wall of the thickening pan through a linkage mechanism.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Please refer to Figures 1 to 4 This utility model provides a high-efficiency slurry thickener, which aims to solve the problems of existing slurry thickeners where the stirring rake is prone to structural deformation due to uneven stress and slurry tends to adhere to the inner wall of the thickening pan, affecting the thickening efficiency.

[0027] like Figure 1As shown, the high-efficiency slurry thickener includes a thickening pan 8 as the main container and a support 9 fixedly connected to the bottom of the thickening pan 8. The support 9 provides a stable installation and support foundation for the thickening pan 8. The high-efficiency slurry thickener also includes a stand 3, which is fixed on the support 9. A motor 4 is installed and fixed on the stand 3. The motor 4 drives the stirring rake 6 to rotate through a vertically set transmission shaft 5. The stirring rake 6 is rotatably set inside the thickening pan 8 and is used to stir the slurry in the thickening pan 8.

[0028] To improve the stability and concentration efficiency of the equipment, the high-efficiency slurry thickener further includes a reinforcing component 1 and a wall scraping mechanism 2. The reinforcing component 1 is fixedly installed above the thickening pan 8 and provides radial support for the rotation of the drive shaft 5, thereby enhancing the structural rigidity of the entire mixing system and preventing deformation. The wall scraping mechanism 2 is fixedly connected to the drive shaft 5 and rotates synchronously with the drive shaft 5. The wall scraping mechanism 2 has an inner wall scraper 206. When the wall scraping mechanism 2 rotates, the inner wall scraper 206 is driven to closely adhere to the inner wall of the thickening pan 8, thereby achieving continuous cleaning of the slurry adhering to the inner wall.

[0029] Specifically, the reinforcement component 1 is described in detail. The reinforcement component 1 includes a connecting column 103, a reinforcing column 104, and a reinforcing beam 105, which form the main support structure. The connecting column 103 strengthens the connection between the reinforcement component 1 and the stirring rake 6. The reinforcing column 104 and the reinforcing beam 105 are connected at their ends, forming a triangular stabilizing structure with the stirring rake 6. This triangular stabilizing structure provides stable support for the drive shaft 5 and the stirring rake 6, effectively preventing the drive shaft 5 from being damaged during driving of the stirring rake 6. During the process, if the force causes swaying or wobbling, the reinforcement component 1 also includes a reinforcement ring 101 and a reinforcement rod 102. The reinforcement ring 101 is coaxially arranged outside the transmission shaft 5, and there is a gap between the reinforcement ring 101 and the transmission shaft 5 to allow the transmission shaft 5 to rotate freely. One end of the reinforcement rod 102 is fixedly connected to the reinforcement ring 101, and the other end of the reinforcement rod 102 is connected to the wall scraping mechanism 2. The reinforcement rod 102 reinforces the structure of the wall scraping mechanism 2, further improving the stability of the wall scraping mechanism 2 during rotation.

[0030] The wall scraping mechanism 2 includes a column 201 fixed to the drive shaft 5 and rotating together with the drive shaft 5. The column 201 serves as the main support rod of the wall scraping mechanism 2. The inner wall scraper 206 is movably connected to the column 201 through a set of precise linkage mechanisms. This linkage mechanism ensures that the inner wall scraper 206 can always effectively fit the arc-shaped inner wall of the concentration plate 8 during rotation.

[0031] The linkage mechanism specifically includes an arc rod 202 and a connecting rod 203. The arc rod 202 is arc-shaped to accommodate the rotational movement space within the concentrator 8. One end of the arc rod 202 is connected to the column 201 via a connection method, and one end of the connecting rod 203 is also connected to the other end of the arc rod 202 via a connection method. The other end of the connecting rod 203 is used to connect to the inner wall scraper 206. When the drive shaft 5 drives the column 201 to rotate, under the combined action of centrifugal force and the linkage mechanism, the inner wall scraper 206 is pushed towards and adheres to the inner wall of the concentrator 8. This hinged linkage structure composed of the column 201, the arc rod 202, and the connecting rod 203 ensures the flexibility of the inner wall scraper 206 during movement and its good adaptability to the inner wall.

[0032] To further enhance the structural stability and connection reliability of the linkage mechanism, the linkage mechanism also includes a connecting block 204 and a central connecting shaft 205. The connecting rod 203 is connected to the arc rod 202 through the connecting block 204, and the central connecting shaft 205 passes through the connecting block 204, providing a stable and reliable rotation axis for the rotational connection between the connecting rod 203 and the arc rod 202, ensuring the smoothness and precision of the wall scraping action.

[0033] As a preferred embodiment, to enhance the support stability and torsional resistance of the drive shaft 5, refer to Figure 4 The reinforcement component 1 specifically includes a connecting column 103, a reinforcement column 104, and a reinforcement beam 105. The ends of these three components are fixedly connected to each other to form a geometrically stable and extremely rigid triangular stable structure. This structure directly supports the external bearing seat or support structure of the transmission shaft 5, thereby effectively absorbing the radial and axial forces generated during stirring.

[0034] As another preferred embodiment, to simultaneously reinforce the rotational stability of the scraping mechanism 2, refer to Figure 4 The reinforcement component 1 also includes a reinforcement ring 101 and a reinforcement rod 102. The reinforcement ring 101 is coaxially disposed outside the transmission shaft 5 and remains in a non-contact state with the transmission shaft 5. One end of the reinforcement rod 102 is fixedly connected to the reinforcement ring 101, and the other end of the reinforcement rod 102 is fixedly connected to the column 201 of the wall scraping mechanism 2. In this way, an additional stable support point is provided for the high-speed rotating wall scraping mechanism 2.

[0035] As a preferred structural feature of the scraping mechanism 2, the column 201 of the scraping mechanism 2 is vertically fixed to the outer periphery of the transmission shaft 5. The inner wall scraper 206 is movably connected to the column 201 through a linkage mechanism consisting of an arc rod 202, a connecting rod 203, a connecting block 204, and a central connecting shaft 205. Specifically, one end of the arc rod 202 is connected to the column 201, and the other end of the arc rod 202 is connected to one end of the connecting rod 203 through the connecting block 204 and the central connecting shaft 205. The other end of the connecting rod 203 is fixedly connected to the inner wall scraper 206. This linkage mechanism ensures that the inner wall scraper 206 can adaptively conform to the inner wall of the concentration tray 8.

[0036] In a preferred embodiment, to achieve automatic collection of concentrated materials, a rake rod 7 is fixedly provided at the bottom of the stirring rake 6. The length and tilt angle of the rake rod 7 are designed to ensure that the material at the bottom of the concentration pan 8 can be scraped and collected without any dead angles.

[0037] As a preferred limitation of the discharge structure, a receiving bucket 10 for receiving materials is provided at the bottom center of the concentration plate 8, and the discharge pipe 11 is connected to the bottom of the receiving bucket 10 to form a continuous discharge channel.

[0038] As a preferred method for the mounting structure of power components, refer to Figure 1 and Figure 3 The high-efficiency slurry thickener also includes a platform 3, which is fixed to the upper end of the support 9, providing a horizontal and stable mounting surface for the motor 4, which is then mounted and fixed to the top surface of the platform 3.

[0039] Working principle: When the slurry needs to be concentrated, the slurry is transported into the concentration pan 8. Then the motor 4 is started, and the power is transmitted through the transmission shaft 5, which drives the stirring rake 6 to rotate in the concentration pan 8. The stirring rake 6 stirs the slurry, which promotes the solid particles in the slurry to settle faster, thus achieving the initial concentration of the slurry.

[0040] During the rotation of the stirring rake 6, the reinforcement component 1, which is fixedly set above the concentration pan 8, plays a supporting role. The triangular stable structure formed by the connecting column 103, the reinforcement column 104 and the reinforcement beam 105 provides stable radial support for the drive shaft 5, ensuring that the drive shaft 5 will not sway or deform when subjected to huge stirring resistance. At the same time, the wall scraping mechanism 2, which is fixedly connected to the drive shaft 5, rotates synchronously. The column 201 drives the linkage mechanism composed of components such as the arc rod 202 and the connecting rod 203 to move, so that the inner wall scraper 206 is pushed towards and closely adheres to the inner wall of the concentration pan 8, continuously scraping off the slurry attached to the wall surface, preventing the slurry from accumulating on the wall surface. The reinforcement ring 101 and the reinforcement rod 102 in the reinforcement component 1 also provide structural reinforcement for the high-speed rotating wall scraping mechanism 2, enhancing the stability of the overall stirring and wall scraping structure.

[0041] Once the slurry concentrate has settled to the bottom of the concentration pan 8, the rake rod 7 installed under the stirring rake 6 will scrape the concentrated slurry into the collection tank 10 located at the center of the bottom of the concentration pan 8. Finally, the concentrated slurry will be discharged through the discharge pipe 11 connected to the collection tank 10, thus completing the efficient concentration treatment of the slurry.

[0042] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model 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 utility model should be included within the protection scope of the present utility model.
