Description

Technical Field

[0001] This utility model relates to the technical field of titanium concentrate concentration equipment, and is a device for adjusting the angle of the thickening bucket scraper in the titanium concentrate concentration process. Background Technology

[0002] In the titanium concentrate processing flow, the thickener is a key piece of equipment for achieving titanium concentrate concentration and separation. Its core function is to separate solid particles (titanium concentrate) from the liquid in the slurry through gravity settling. The scraper, as an important component inside the thickener, needs to scrape off the titanium concentrate sludge layer that has settled to the bottom and transport it to the discharge port to complete the thickening operation. However, most existing thickener scrapers adopt a fixed installation structure, and their angle cannot be adjusted according to actual production conditions. When dealing with titanium concentrate slurries of different concentrations and particle sizes, the fixed-angle scraper is prone to problems such as incomplete scraping or excessive scraping resistance. For example, when the slurry concentration is high and the solid particles are coarse, the fixed-angle scraper cannot fully contact the mud layer, resulting in some slurry remaining at the bottom of the thickening hopper. This not only reduces the recovery rate of titanium concentrate, but also requires periodic shutdowns to clean the residual slurry, affecting the continuity of production. On the other hand, when the slurry concentration is low and the particles are fine, the excessive contact area between the scraper and the bottom will generate greater resistance, increasing the energy consumption of the power unit. In fact, the excessive resistance may even cause the scraper to deform or be damaged, increasing equipment maintenance costs.

[0003] Meanwhile, the few existing thickener scrapers with angle adjustment functions have complex adjustment mechanisms and low adjustment accuracy. These mechanisms often employ a linkage structure, requiring the coordinated action of multiple components to achieve angle adjustment. This not only makes assembly difficult but also makes them prone to wear between components, leading to decreased adjustment accuracy and making it difficult to accurately control the scraper's angle position. Furthermore, the lack of effective angle indication and positioning structures during adjustment forces operators to rely on experience to judge the scraper's angle, making it impossible to accurately match the optimal scraping angle for different working conditions, further impacting the efficiency and stability of thickening operations.

[0004] Furthermore, existing thickener scraping mechanisms are mostly of a single, integrated design, with multiple scraper blades connected by the same transmission structure. When a scraper blade malfunctions or wears out, the entire unit must be disassembled for repair, which not only prolongs maintenance time but also increases maintenance costs. Simultaneously, the fixed spacing of the scraper blades in this integrated mechanism cannot be adjusted according to factors such as the diameter of the thickener and the flow characteristics of the slurry, resulting in uneven scraping coverage and ineffective removal of sludge in some areas, further reducing the efficiency and quality of titanium concentrate thickening. These problems severely restrict the efficiency, stability, and economy of titanium concentrate thickening operations, necessitating a simple, precisely adjustable, and easily maintained thickener scraper blade angle adjustment device to address these shortcomings. Summary of the Invention

[0005] This invention provides a thickening bucket scraper angle adjustment device for the titanium concentrate thickening process, which overcomes the shortcomings of the prior art and can effectively solve the problems of fixed scraper angle, low adjustment accuracy, inconvenient maintenance and low thickening efficiency in the existing thickening bucket.

[0006] The technical solution of this utility model is achieved through the following measures: a thickening bucket scraper angle adjustment device for a titanium concentrate thickening process, comprising a cylinder, a climbing frame, a main rotating shaft, a power unit, a connecting shaft, an adjustment device, a fixed plate, an adjustment shaft, a gear, a gear ring, an adjustment rod, and an adjustment connecting rod; the climbing frame is arranged inside the cylinder, and the two ends of the main rotating shaft are respectively connected to the power unit and the climbing frame; the fixed plate is fixedly connected to the main rotating shaft; the adjustment shaft passes through the fixed plate and is connected to the gear, the gear meshes with the gear ring, and the gear ring is connected to the adjustment device; the adjustment device includes a transverse connecting rod and a longitudinal connecting part, one end of the transverse connecting rod is fixedly connected to the gear ring, and the other end is perpendicularly fixedly connected to the longitudinal connecting part, and the end of the longitudinal connecting part away from the transverse connecting rod is movably connected to the adjustment rod; one end of the adjustment rod is movably connected to the adjustment device.

[0007] Preferably, multiple independent scraper mechanisms are fixedly connected to the bottom outer wall of the climbing frame. The scraper mechanisms are movably connected to the climbing frame via connecting shafts, and the end of the adjusting connecting rod away from the adjusting rod is movably connected to the scraper mechanism.

[0008] Preferably, the scraper mechanism may include a mounting box, the top outer wall of which has a threaded hole, and a screw is screwed into the inner wall of the threaded hole; a rotating disk is fixedly connected to the top outer wall of the screw, and a rectangular opening is opened on the bottom outer wall of the mounting box, with a scraper seat slidably connected to the inner wall of the rectangular opening.

[0009] Preferably, an angle scale can be mounted on the fixed plate, and an angle indicator can be provided on the adjustment device, with the angle indicator cooperating with the angle scale on the fixed plate.

[0010] Preferably, the outer wall of the adjusting shaft may be provided with an angle positioning scale, and the adjusting shaft is fixedly connected to the gear.

[0011] Preferably, an angle limiting block may be provided at the connection between the connecting shaft and the climbing frame, and the angle limiting block is fixedly connected to the climbing frame.

[0012] Preferably, the outer wall of the rotating disk may be provided with anti-slip protrusions, which are evenly distributed along the circumference of the rotating disk.

[0013] Preferably, the fixing plate can be a circular plate structure, and the fixing plate is set perpendicular to the main rotating shaft.

[0014] Preferably, there can be multiple scraper mechanisms, and the multiple scraper mechanisms are distributed at equal intervals along the length of the climbing frame.

[0015] Preferably, the power unit can be an electric motor, and the output shaft of the electric motor is connected to the main rotating shaft.

[0016] This invention employs a combined structure of a transverse connecting rod and a longitudinal connecting part, coupled with the meshing transmission of gears and gear rings. Rotating the adjusting shaft drives the gears to rotate, which in turn drives the gear ring and adjusting device to move synchronously, achieving an angle change in the adjusting rod. Finally, the adjusting connecting rod drives the scraper mechanism to rotate around the connecting shaft, completing the precise adjustment of the scraper angle. Compared to existing fixed-angle or complex linkage structures, the adjustment process is simpler and more precise, quickly matching the working conditions of different slurry concentrations and particle sizes, improving the thoroughness of scraping and equipment operating efficiency. Secondly, the design of multiple independent scraper mechanisms not only allows for flexible adjustment of the number and spacing according to the actual size of the thickening hopper, ensuring uniform scraping coverage, but also allows for individual disassembly and repair in case of a single scraper mechanism failure, significantly reducing maintenance costs and downtime. Furthermore, the angle scale on the fixed plate works in conjunction with the angle indicator on the adjustment device to display the adjustment angle of the scraper mechanism in real time. The angle positioning scale on the adjustment shaft further improves the adjustment accuracy, avoiding the problem of operators judging the angle based solely on experience. The anti-slip protrusions on the outer wall of the rotating disk enhance the grip stability during operation and facilitate the rotation adjustment of the screw. The angle limit block can limit the maximum swing angle of the scraper mechanism, preventing damage to components due to over-adjustment and improving the safety of equipment operation.

Detailed Implementation

[0022] This utility model is not limited to the following embodiments, and the specific implementation method can be determined according to the technical solution of this utility model and the actual situation.

[0023] The present invention will be further described below with reference to embodiments: Example 1: As Figure 1 , 2 As shown in Figures 3 and 4, this embodiment provides a thickener bucket scraper angle adjustment device for a titanium concentrate thickening process, including a cylinder 1, a climbing frame 2, a main rotating shaft 4, a power unit 7, a connecting shaft 20, an adjustment device 5, a fixing plate 9, an adjustment shaft 10, a gear 11, a gear ring 12, an adjustment rod 17, and an adjustment connecting rod 18. The climbing frame 2 is arranged inside the cylinder 1, and the two ends of the main rotating shaft 4 are respectively connected to the power unit 7 and the climbing frame 2. The fixing plate 9 is fixedly connected to the main rotating shaft 4. The adjustment shaft 10 passes through the fixing plate 9 and is connected to the gear 11. The gear 11 meshes with the gear ring 12, and the gear ring 12 is connected to the adjustment device 5. The adjustment device 5 includes a transverse connecting rod and a longitudinal connecting part. One end of the transverse connecting rod is fixedly connected to the gear ring 12, and the other end is vertically fixedly connected to the longitudinal connecting part. The end of the longitudinal connecting part away from the transverse connecting rod is movably connected to the adjustment rod 17. One end of the adjustment rod 17 is movably connected to the adjustment device 5. During operation, after the power unit 7 starts, it drives the main rotating shaft 4 to rotate via the output shaft. The main rotating shaft 4 further drives the climbing frame 2 to rotate inside the cylinder 1. The scraper mechanism 6 at the bottom of the climbing frame 2 rotates synchronously with the climbing frame 2, realizing the scraping operation of the sludge at the bottom of the cylinder 1. When it is necessary to adjust the angle of the scraper mechanism 6, the adjusting shaft 10 is rotated. The adjusting shaft 10 drives the gear 11 to rotate. The gear 11 meshes with the gear ring 12, causing the gear ring 12 to drive the adjusting device 5 to move synchronously. The transverse connecting rod of the adjusting device 5 is linked with the longitudinal connecting part, changing the angle of the adjusting rod 17. The adjusting rod 17 drives the scraper mechanism 6 to rotate around the connecting shaft 20 through the adjusting connecting rod 18, completing the angle adjustment. In this way, the angle of the scraper can be conveniently adjusted to adapt to different slurry conditions. At the same time, the stable connection between the climbing frame 2 and the main rotating shaft 4 ensures the continuity of the scraping operation and improves the concentration efficiency of titanium concentrate.

[0024] In this invention, multiple independent scraper mechanisms 6 are fixedly connected to the bottom outer wall of the climbing frame 2. The scraper mechanisms 6 are movably connected to the climbing frame 2 via connecting shafts 20, and the end of the adjusting connecting rod 18 furthest from the adjusting rod 17 is movably connected to the scraper mechanism 6. The number of independent scraper mechanisms 6 can be flexibly set according to the diameter of the cylinder 1 and the distribution of the slurry, ensuring uniform coverage of the scraped mud and avoiding localized mud residue. The scraper mechanism 6 is movably connected to the climbing frame 2 via connecting shafts 20, providing a rotation fulcrum for angle adjustment. Simultaneously, the connection of the adjusting connecting rod 18 ensures that the movement of the adjusting rod 17 is accurately transmitted to the scraper mechanism 6, guaranteeing synchronous adjustment. This improves the comprehensiveness of mud scraping and the reliability of adjustment, and allows for individual repair of a single scraper mechanism 6 in case of failure, reducing maintenance costs.

[0025] In this invention, the scraper mechanism 6 includes a mounting box 61, a screw 62, a rotating disk 63, and a scraper seat 64. The mounting box 61 has a threaded hole on its top outer wall, and the screw 62 is screwed into the inner wall of the threaded hole. The rotating disk 63 is fixedly connected to the top outer wall of the screw 62. The mounting box 61 has a rectangular opening on its bottom outer wall, and the scraper seat 64 is slidably connected to the inner wall of the rectangular opening. The mounting box 61 is the core supporting component of the scraper mechanism 6. The threaded hole on its top provides the mounting base for the screw 62. Rotating the rotating disk 63 can drive the screw 62 to rise and fall within the threaded hole. The screw 62 further pushes or pulls the scraper seat 64 to slide within the rectangular opening at the bottom of the mounting box 61, achieving fine-tuning of the scraper seat 64's position and ensuring the fit between the scraper seat 64 and the bottom of the cylinder 1, thus improving the thoroughness of sludge scraping. This allows for fine-tuning of the scraper seat 64's position, optimizing the sludge scraping effect. Simultaneously, the rotating disk 63 facilitates manual adjustment by the operator, improving operational convenience.

[0026] In this invention, an angle scale is mounted on the fixed plate 9, and an angle indicator is provided on the adjusting device 5. The angle indicator cooperates with the angle scale on the fixed plate 9. The angle scale is clearly marked with angle values. When the adjusting device 5 is activated, the angle indicator moves synchronously with the adjusting device 5. By cooperating with the angle scale, the operator can read the adjustment angle of the scraper mechanism 6 in real time, avoiding errors caused by judging the angle solely based on experience, ensuring adjustment accuracy, and quickly matching the optimal sludge scraping angle. This enables visualized angle adjustment, improves adjustment accuracy, reduces working condition adaptation time, and increases production efficiency.

[0027] In this invention, the outer wall of the adjusting shaft 10 is provided with an angle positioning scale, and the adjusting shaft 10 is fixedly connected to the gear 11. The angle positioning scale on the outer wall of the adjusting shaft 10 can assist the operator in controlling the rotation angle, ensuring that the angle is accurate and consistent each time, and avoiding over-rotation or under-adjustment; the fixed connection between the adjusting shaft 10 and the gear 11 ensures that the power of the adjusting shaft 10 can be fully transmitted to the gear 11, avoiding transmission slippage and improving the stability and reliability of the adjustment. This further improves the accuracy of angle adjustment, ensures the stability of the transmission between the gear 11 and the gear ring 12, and guarantees the adjustment effect.

[0028] In this invention, an angle limiting block is provided at the connection between the connecting shaft 20 and the climbing frame 2, and the angle limiting block is fixedly connected to the climbing frame 2. The angle limiting block can limit the maximum swing angle of the scraper mechanism 6 around the connecting shaft 20, preventing the scraper mechanism 6 from colliding with the inner wall of the cylinder 1 or other components due to excessive adjustment by the operator, avoiding deformation and damage to the components, and protecting transmission components such as the adjusting connecting rod 18, thus extending the service life of the equipment. This improves the safety of equipment operation, avoids component damage caused by excessive adjustment, and reduces the frequency of equipment maintenance.

[0029] In this invention, the outer wall of the rotating disk 63 is provided with anti-slip protrusions, which are evenly distributed around the circumference of the rotating disk 63. These anti-slip protrusions increase the friction between the operator's hand and the rotating disk 63, preventing slippage during rotation. Especially when hands are contaminated with slurry or oil, the operator can still stably grip and rotate the rotating disk 63, ensuring smooth adjustment of the screw 62 and improving operational safety and convenience. This enhances the operational stability of the rotating disk 63, prevents adjustment interruptions due to slippage, and ensures a smooth adjustment process.

[0030] In this invention, the fixing plate 9 is a circular plate structure, and it is perpendicular to the main rotating shaft 4. The circular plate structure of the fixing plate 9 ensures uniform force distribution, stably supporting components such as the adjusting shaft 10 and gear 11, preventing component misalignment due to uneven force. The perpendicular alignment of the fixing plate 9 with the main rotating shaft 4 ensures that the axis of the adjusting shaft 10 is parallel to the axis of the main rotating shaft 4, resulting in more precise meshing of the gear 11 and gear ring 12, reducing transmission wear, and improving transmission efficiency. This enhances the support stability of the fixing plate 9 and the meshing accuracy of the transmission components, extends the service life of the components, and ensures the normal operation of the adjusting mechanism.

[0031] In this invention, there are multiple scraper mechanisms 6, which are evenly distributed along the length of the climbing frame 2. This even distribution of multiple scraper mechanisms 6 along the climbing frame 2 ensures that each scraper mechanism 6 can uniformly cover different areas of the bottom of the cylinder 1 when the climbing frame 2 rotates, avoiding blind spots in scraping and ensuring that the sludge is fully scraped off and transported to the discharge port, thus improving the recovery rate of titanium concentrate. Simultaneously, the even distribution ensures balanced force on the climbing frame 2, preventing deformation due to uneven component distribution. This achieves comprehensive scraping of the sludge at the bottom of the cylinder 1, improving the recovery rate of titanium concentrate, while also ensuring the structural stability of the climbing frame 2 and extending the service life of the equipment.

[0032] In this invention, the power unit 7 is an electric motor, and the output shaft of the motor is connected to the main rotating shaft 4. The electric motor, as the power unit 7, features low energy consumption, stable power output, and convenient control. Its direct connection to the main rotating shaft 4 reduces power transmission losses, ensuring that the main rotating shaft 4 can stably drive the climbing frame 2 to rotate. Simultaneously, the motor's speed can be adjusted through the control system to adapt to the sludge scraping requirements under different slurry concentrations, improving the equipment's adaptability. This provides stable and efficient power to the climbing frame 2, reduces energy loss, and allows for speed adjustment, further adapting to different production conditions.

[0033] During operation, the optimal angle of the scraper mechanism 6 and the position of the scraper seat 64 are first determined based on the concentration and particle size of the titanium concentrate slurry. The rotating disk 63 is rotated, causing the screw 62 to rise and fall within the threaded hole of the mounting box 61, pushing the scraper seat 64 to slide within the rectangular opening, ensuring a suitable fit between the scraper seat 64 and the bottom of the cylinder 1. Then, the adjusting shaft 10 is rotated, and the rotation angle is controlled according to the angle positioning scale on the outer wall of the adjusting shaft 10. The adjusting shaft 10 drives the gear 11 to rotate, and the gear 11 meshes with the gear ring 12, causing the adjusting device 5 to operate synchronously. The angle indicator moves along the angle scale of the fixed plate 9, and the adjustment stops when the indicator points to the preset angle. The motor of the power unit 7 is started, and the motor output shaft drives the main rotating shaft 4 to rotate. The main rotating shaft 4 drives the climbing frame 2 to rotate inside the cylinder 1. Multiple scraper mechanisms 6 at the bottom of the climbing frame 2 rotate synchronously with the climbing frame 2, scraping off the titanium concentrate mud layer at the bottom of the cylinder 1. The mud layer is transported to the discharge port along the inclined direction of the scraper mechanism 6, completing the concentration operation. If the slurry conditions change during the operation, the above adjustment steps can be repeated to adjust the angle of the scraper mechanism 6 and the position of the scraper seat 64 to ensure the mud scraping effect. Overall, this device effectively improves the efficiency and recovery rate of titanium concentrate concentration through precise angle adjustment, uniform mud scraping coverage, and stable power output. It also has the advantages of convenient maintenance and high safety, and is suitable for long-term continuous production.
