Description

Technical Field

[0001] The utility model relates to the technical field of transport stirring devices, in particular to a monazite ore powder pre-stirring device. Background Art

[0002] With the increasing application of rare earth resources in the field of high-tech, monazite ore, as an important source of rare earth elements, has also received widespread attention for its mining and processing technology. The process of grinding monazite ore into powder not only reduces the particle size of monazite, but also increases its specific surface area, which increases the subsequent contact area between monazite and decomposition agents (such as CaO, CaCl2, NaOH, etc.). The monazite ore powder after grinding into powder is smaller in volume and lighter in weight, which is convenient for storage and transportation.

[0003] During the traditional transportation or pushing of monazite ore powder for processing, due to factors such as environmental humidity, the ore powder easily absorbs moisture in the air, resulting in increased humidity, which affects the effect of its subsequent processing. Long-term accumulation may also cause the ore powder to form lumps at the bottom. Utility Model Content

[0023] In order to more clearly understand the above-mentioned objects, features and advantages of the present invention, the present invention will be further described below with reference to the accompanying drawings and embodiments.

[0024] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways than those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification. The present invention is further described in detail below with reference to the accompanying drawings.

[0025] A monazite ore powder pre-mixing device, such as Figures 1-4 As shown, it includes a pushing cart 1, a mixing barrel 2 and a spiral feeder 3. The pushing cart 1 is fixedly installed with the mixing barrel 2 through a barrel fixing frame 9. The mixing barrel 2 is clamped with a top cover 7. The top cover 7 is provided with a motor stirring fan 5 and a feeding port 8. The motor stirring fan 5 is arranged inside the mixing barrel 2 through the top cover 7. The spiral feeder 3 is located between the pushing cart 1 and the mixing barrel 2. The spiral feeder 3 is movably installed on the pushing cart 1 through an angle adjustment component 4. The barrel fixing frame 9 is a square steel frame structure. A round groove is opened on the top surface thereof to match the mixing barrel 2 and is welded thereto. A handle is installed at one end. The pushing cart 1 adopts a brake wheel 10 to facilitate movement and fixation during feeding. A protruding clamp ring is provided on the top cover 7 to match the inner wall of the mixing inner barrel 21 in the mixing barrel 2. The installation is completed with the mixing barrel 2 through a sealing gasket to ensure sealing. A heating plate 22 is installed inside the mixing barrel 2. The heating plate 2 2 can heat the mixing barrel 2 to make the mixing barrel 2 in a dry state, and fully stir and dry it through the motor stirring fan 5 to avoid accumulation. The angle adjustment component 4 is movably installed on the push car 1, and the angle of the spiral feeder 3 can be flexibly adjusted to meet the needs of different working scenarios. The motor stirring fan 5 includes a motor and three stirring fans installed on the output shaft in sequence. The first two stirring fans have the same structure, and the third stirring fan is adapted to the discharge section of the mixing barrel 2. The output shaft extends into the end of the telescopic tube 6 with a threaded cutter to stir the mineral powder at the bottom at all times, and the distance the output shaft extends into the telescopic tube 6 is a certain distance from the bottom connected to the telescopic tube 6 and the spiral feeder 3 to avoid passing through the telescopic tube 6 during vibration and colliding with the spiral feeder 3. Pre-stirring and heating are performed during the transportation of the mineral powder to avoid a series of effects caused by moisture and agglomeration on subsequent work.

[0026] The feeding port 8 is funnel-shaped, and a sealing cover is installed at the large circular through hole on the top. The motor in the motor stirring fan 5 is installed on the top surface of the top cover 7, and the output shaft passes through the top cover 7 into the mixing barrel 2. The top cover 7 is disassembled and the sealing gasket is removed to repair or clean the motor stirring fan 5 or the mixing barrel 2.

[0027] The mixing barrel 2 includes an inner mixing cylinder 21, a buffer assembly 23 and an outer cylinder 24. The outer cylinder 24 is sleeved on the outer surface of the inner mixing cylinder 21. The buffer assembly 23 is installed between the outer cylinder 24 and the inner mixing cylinder 21. The heating plate 22 is attached to the outer surface of the inner mixing cylinder 21. The inner mixing cylinder 21 is connected to the spiral feeder 3 through the telescopic tube 6. The heating plate 22 is located between the inner cylinder of the stirring rod and the outer cylinder 24. The lower half of the inner mixing cylinder 21 is funnel-shaped. Although the funnel-shaped design mainly affects the discharge of materials, it also indirectly promotes the uniformity of the stirring process. The material in the inner mixing cylinder 21 forms a more natural convection or vortex during stirring. The outer cylinder 24 is sleeved on the outer surface of the inner mixing cylinder 21 and is connected through the buffer assembly 23. It not only provides additional support for the inner mixing cylinder 21, but also reduces the vibration and impact of the mineral powder during stirring through the buffer assembly 23. During vibration, the telescopic tube 6 can be freely extended and retracted to ensure stable connection under different working conditions, thereby improving the adaptability and reliability of the equipment.

[0028] The buffer assembly 23 includes a plurality of spring columns 231 and a plurality of shock-absorbing airbags 232. The plurality of spring columns 231 are located between the outer surface side wall of the mixing inner cylinder 21 and the inner surface side wall of the outer cylinder 24. The plurality of shock-absorbing airbags 232 are installed at the bottom of the inner surface of the outer cylinder 24. The plurality of shock-absorbing airbags 232 are arranged in a ring shape with the axis of the telescopic tube 6 as the center, and the shock-absorbing airbags 232 are arranged at the outer surface position of the telescopic tube 6. The shock-absorbing airbags 232 are annular and avoid the telescopic tube 6 connected to the mixing inner cylinder 21, ensuring that the shock-absorbing airbags 232 play the best shock-absorbing effect without affecting the normal operation of the material conveying and the mixing inner cylinder 21, ensuring the shock-absorbing effect and avoiding interference with the material conveying process, thereby improving the stability and reliability of material conveying. The spring columns 231 effectively prevent the heating plate 22 from hitting the inner wall of the outer cylinder 24 due to shaking. The spring columns 231 absorb and disperse the impact force and vibration from the stirring process, and the shock-absorbing airbags 232 further attenuate the vibration energy.

[0029] The pushing trolley 1 is provided with a slide and an adjustment groove, and the angle adjustment assembly 4 includes a connecting piece 41, a support seat 42 and a pushing cylinder 43. The connecting piece 41 is movably mounted on the pushing trolley 1 through a fixed roller, and the pushing cylinder 43 is fixedly mounted in the pushing trolley 1, and the support seat 42 is mounted on the telescopic end of the pushing cylinder 43. The conveying end of the pushing cylinder 43 is located in the slide, and the fixed roller is located in the adjustment groove. The end of the screw feeder 3 is fixedly mounted on the connecting seat, and the feeding section of the screw feeder 3 is slidably connected to the support seat 42. The adjustment groove effectively avoids the collision of the pushing trolley 1 when the bevel angle of the screw feeder 3 is adjusted. By pushing the extension and contraction of the cylinder 43, the support seat 42 can be driven to move in the slide, thereby realizing the angle adjustment of the connecting seat at the end of the screw feeder 3 and its feeding section. The flexibility brought by the angle adjustment assembly 4 enables the screw feeder 3 to be positioned more accurately to the optimal feeding angle. The connection part of the screw feeder 3 and the telescopic tube 6 is equipped with an electric valve, which controls the feeding state through the electric valve.

The content not described in detail in this manual belongs to the existing technology known to professional and technical personnel in this field.

[0031] Working principle: Move the device to the powder loading position, adjust the brake wheel 10 to the parked state, open the cover of the feeding port 8 to load the powder, and then the monazite ore powder enters the mixing inner cylinder 21. After it is full, install the cover. During transportation, turn on the heating plate 22 to keep the air in the mixing inner cylinder 21 in a dry state. The ore powder in the mixing inner cylinder 21 is dried by the hot air. At the same time, turn on the motor stirring fan 5 to heat the ore powder evenly and ensure that the ore powder is not stratified or agglomerated into lumps, ensuring that it is completely dry. The buffer component 23 absorbs and reduces external vibrations.

[0032] When discharging, the support base 42 is moved by pushing the cylinder 43 to adjust the feeding angle of the spiral feeder 3. At this time, the electric valve is opened to discharge the material;

[0033] When maintenance and cleaning are performed, it is only necessary to remove the top cover 7 to clean or maintain the mixing barrel 2 and the motor stirring fan 5.
