[0002] In the process of preparing titanium dioxide in the laboratory, the filtered slurry needs to be beaten for comminution. However, there is no fixed container for laboratory beating and dispersion at present. A beaker can be used. The container is simple and easy to clean, but there are safety hazards in the operation process. If the beaker breaks during high-speed dispersion, the safety of the experimenter cannot be guaranteed, and the slurry will also splash in the laboratory and be difficult to clean.

[0003] Compared with the danger of a glass beaker, a plastic bucket is a safer container for laboratory beating and dispersion. However, when using a plastic bucket for experiments, it is in an upright state, and coarse particles are easy to deposit at the bottom of the bucket and cannot be evenly dispersed, resulting in poor beating effect; and it affects the overall beauty of the laboratory and is also easy to break after a long time.

[0004] The stainless steel tank equipped with a high-speed disperser can also be used for beating, but the tank body is small, the beating volume is too small to meet the requirements of laboratory tests, and it is very heavy and inconvenient to operate.

[0005] In view of this, the prior art should be improved to solve the above technical problems existing in the prior art. Content of the Utility Model

[0033] As Figure 1 shown, the present utility model provides a horizontal pulping and dispersing tank for laboratory use, which comprises:

[0034] A dispersing tank body 1, the dispersing tank body 1 can rotate on its own, and is provided with a feed inlet 4 and a discharge outlet 5. Fixed columns 7 are arranged on the inner side wall of the dispersing tank body 1; a dispersing shaft 6, the dispersing shaft 6 is connected to the fixed columns 7 and extends between the opposite side walls of the dispersing tank body 1; a motor 8, the motor 8 is arranged on the dispersing tank body 1 and is used to drive the dispersing shaft 6 to rotate; a plurality of stirring blades 9, the stirring blades 9 are arranged on the dispersing shaft 6, and the plurality of stirring blades 9 include triangular blades and / or elliptical blades and / or square blades; a support frame 10 and a vibration damping frame 11, the support frame 10 and the vibration damping frame 11 are arranged at the bottom of the outer tank body for support and vibration damping.

[0035] The fixed columns 7 can be arranged on the inner surface of the first side wall of the dispersing tank body 1, the motor 8 can be arranged on the outer surface of the second side wall of the dispersing tank body 1 opposite to the first side wall, and the two ends of the dispersing shaft 6 are respectively connected to the fixed columns 7 and the motor 8, so as to extend between the first side wall and the second side wall.

[0036] In the horizontal pulping and dispersing tank for laboratory use according to an embodiment of the present utility model, titanium dioxide slurry is added from the feed port 4, and the motor 8 drives the dispersing shaft 6 to rotate. Under the action of the high-speed motor 8, the titanium dioxide slurry is dispersed in the pulping tank. Larger particles sink to the bottom and rise along the blades under the action of the stirring blades 9, and the titanium dioxide particles are sheared under the action of the blades, which can produce a dispersing effect. At the same time, the dispersing tank can rotate itself, so that the coarse particles deposited at the bottom are driven to the upper part for secondary shearing. The whole device has the advantages of fast pulping speed and good dispersing effect. At the same time, the support frame 10 can support the dispersing tank body 1 during its rotation process to ensure the stability of the rotation process. In addition, when the motor drives the dispersing shaft 6 to operate, due to the rotation and pulping inside the machine, a huge centrifugal force will be generated in the whole machine, and the machine will vibrate. The present utility model can reduce the violent shaking of the dispersing tank body 1 caused by the centrifugal force by setting the shock-absorbing frame 11, strengthen the safety of the dispersing tank body 1, and protect the dispersing tank body 1.

[0037] Stirring blades 9 of various shapes can produce a double-shearing effect. The specific shape of the stirring blades 9 is not limited. They can be blades with uniform or non-uniform distribution, and can be one or more of triangular blades, elliptical blades or square blades. In addition, serrated, spiral or wing-shaped designs can also be adopted, and the sharp parts of their edges can cut the material during rotation to form fine particles or droplets, realizing shearing in the horizontal direction. The stirring blades 9 themselves can also be bent or inclined and arranged on the dispersing shaft 6, and can rotate under the action of the motor 8 to guide the material to form a circulating flow or vortex in the tank, promoting the full contact and mixing between the materials, and also generating vertical or oblique shearing forces through the intersection of the materials in different flow velocity regions, further refining the material particles to achieve the purpose of double shearing.

[0038] In some specific embodiments, the horizontal pulping and dispersing tank for laboratory use further includes a rotating assembly, which is arranged on the dispersing tank body 1 and is used to drive the dispersing tank body 1 to rotate itself. The rotating assembly includes a self-rotating motor, which is arranged on the dispersing tank body 1 to drive the dispersing tank body 1 to rotate itself. The centrifugal force generated by the self-rotation can evenly disperse the solid particles or droplets in the material into the whole titanium dioxide slurry, avoiding the formation of particle aggregates and improving the stability and uniformity of the product.

[0039] In some specific embodiments, the dispersing tank body 1 includes a sleeved outer tank body and an inner tank body. There is a hollow cavity between the outer tank body and the inner tank body. The outer tank body is provided with a water inlet 2 and a water outlet 3 for providing water at a predetermined temperature into the hollow cavity to adjust the temperature of the slurry in the inner tank body.

[0040] In some specific embodiments, a temperature sensor is provided inside the inner tank. The temperature sensor has a fast response speed and can capture temperature changes within a short period of time, triggering corresponding control mechanisms, such as adjusting the heating or cooling system, to maintain the stability of the temperature inside the tank. The specific implementation of the heating or cooling system is to add hot water or cold water. The temperature sensor can be disposed, for example, on the dispersion shaft 6.

[0041] In some specific embodiments, there are two symmetrically arranged vibration dampers 11. The two symmetrically arranged vibration dampers 11 can ensure that when the device is subjected to the vibration brought by the motor 8, the forces on both sides are balanced, thus avoiding tilting or offset phenomena caused by uneven forces. The two symmetric vibration dampers 11 can respectively absorb and disperse the vibration energy from different directions, forming a double buffering effect, thereby more effectively reducing the vibration amplitude and frequency.

[0042] In some specific embodiments, it further includes a ring 13 sleeved on the outer periphery of the dispersion tank body 1, and the bottom of the ring 13 is fixedly connected to the support frame 10. The connection between the ring 13 and the support frame 10 provides an additional support point for the dispersion tank body 1, enhancing the stability of the entire device. As a connecting member, the ring 13 can disperse the stress on the dispersion tank body 1 to the support frame 10, thereby avoiding device damage caused by local stress concentration. This stress dispersion effect helps to extend the service life of the dispersion tank body 1 and the support frame 10.

[0043] In some specific embodiments, a shock absorber 12 is provided at the top of the vibration damper 11. The shock absorber 12 can reduce the vibration and shaking generated during the operation of the device, enabling the device to operate more stably. This helps to improve the dispersion accuracy of the device, extend the service life of the device, and reduce failures and downtime caused by vibration. Vibration is one of the main sources of noise. The setting of the shock absorber 12 can effectively reduce the noise generated by vibration, improve the working environment, and enhance the comfort and work efficiency of the staff.

[0044] In some specific embodiments, the rotation directions of the plurality of stirring blades 9 are different. Stirring blades 9 with different rotation directions will generate complex flow patterns inside the dispersion tank, including eddies and shear forces in different directions, which helps the titanium dioxide slurry to achieve uniform mixing in a shorter time. Through stirring in different directions, the dead zone area inside the dispersion tank can also be reduced, enabling the titanium dioxide slurry to be effectively mixed throughout the dispersion process, improving the uniformity and efficiency of dispersion.

[0045] In some specific embodiments, the dispersion shaft 6 passes horizontally through the middle of the inner tank body via the fixing column 7. The dispersion shaft 6 arranged in the middle can form a more complex flow pattern in the material, including the swirling flow that flips up and down and the shear force in the horizontal direction. These flow patterns contribute to a more uniform mixing of the material at the microscopic level, improving the quality and stability of the product. During the solid-liquid mixing process, the dispersion shaft 6 arranged in the middle can reduce the sedimentation and stratification of solid particles, making the mixing more uniform. Since in the actual dispersion process, coarse particles are likely to deposit at the bottom, the dispersion shaft 6 can also be arranged in the middle-lower part or the lower part of the inner tank body, so that the coarse particles deposited at the bottom can be driven to the upper part for secondary shearing.

[0046] In some specific embodiments, there is an angle between the stirring blade 9 and the vertical plane longitudinally. This angle design enables the stirring blade 9 to cover a wider area during the stirring process, reducing the dead corners of dispersion, thereby improving the uniformity of mixing.

[0047] In some specific embodiments, high-temperature and corrosion-resistant components are provided on the outer tank body and the inner tank body. The high-temperature and corrosion-resistant components can effectively resist the erosion of the dispersion tank body 1 by harsh environments such as high temperature, acid, and alkali, thus significantly extending the service life of the dispersion tank body 1. This is particularly important for the inner tank body that needs to operate for a long time or is under harsh working conditions. The high-temperature resistance ensures that the inner tank body can still operate stably in a high-temperature environment, preventing safety accidents caused by overheating. Preferably, the materials of the outer tank body and the inner tank body are stainless steel.

[0048] In this application, the wall thickness of the dispersion tank body is 0.1 cm. The dispersion tank body lies horizontally, is of a double-layer structure and hollow inside, with a height of 60 - 80 cm and a cross-sectional diameter of 20 - 30 cm. Such dimensions can process 1.0 - 4.0 kg of slurry at a time.

[0049] Driven by a high-speed motor, the dispersion shaft of the horizontal pulping and dispersion tank for laboratory use of the present utility model rotates rapidly, driving the slurry to achieve all-round high-speed dispersion in the tank body. During this process, larger titanium dioxide particles naturally settle to the bottom of the tank, while the structure of multiple stirring blades cleverly lifts these particles upward along the blade trajectory and implements a double shearing effect during the rising process, effectively promoting the refinement and uniform dispersion of the particles; and with the double support of the support frame and the ring, the tank body can rotate smoothly. This design not only enhances the stability of the system, but more importantly, it enables the coarse particles originally deposited at the bottom of the tank to be automatically brought to the upper part of the tank body to receive secondary or even multiple shearing treatments from the stirring blades. The circulating dispersion mechanism greatly improves the processing efficiency and dispersion effect, ensuring the fineness and uniformity of the final product.
