Description

Technical Field

[0001] The utility model belongs to the field of titanium dioxide production equipment and relates to a titanium dioxide homogenizing device special for chemical fiber masterbatch. Background Art

[0002] In the production process of chemical fiber masterbatch, titanium dioxide homogenization device plays a vital role. Evenly mixing titanium dioxide with other materials has a direct impact on the quality and performance of chemical fiber masterbatch.

[0003] At present, the titanium dioxide homogenizing device for chemical fiber masterbatch is common on the market. Its working principle is to utilize the high-speed rotation and fluid dynamic characteristics of the blades inside the homogenizing tank to make the materials constantly contact and collide, thereby achieving uniform mixing.

[0004] The existing homogenization device of our company has certain limitations in the actual production process. The blades inside the homogenization tank are paddle-type blades with a diameter of Φ800mm, which are driven by electricity and rotate in the left direction. The motor and reducer are directly connected to perform the mixing work.

[0005] However, in actual production operations, when materials are put into the machine, due to this structure and connection method, the materials will have a large impact force on the impeller. This impact force causes the impeller to shake greatly, seriously affecting the stability and working efficiency of the homogenizing device. In addition, the impeller shaking caused by the impact of the material makes the beating and dispersion effect poor.

[0006] The results of material performance analysis of the existing homogenization device are as follows:

[0007] Serial number Transmission volume / ml Water dispersibility 1 20 86.5 2 30 85.1 3 25 85.5 4 20 86 5 30 85.3 6 25 86.2 7 25 85.5 8 30 85.1 9 20 84.5 10 25 86.2 average value 25 85.59

[0008] Table 1: Material performance analysis before transformation

[0009] The various components in the material cannot be fully and evenly mixed together, resulting in uneven quality of chemical fiber masterbatch, which cannot meet the production requirements of high-quality chemical fiber masterbatch. This will not only affect the color uniformity, hiding power and other performance indicators of chemical fiber masterbatch, but may also cause a series of problems in the subsequent chemical fiber production process, such as uneven strength and color deviation of chemical fiber products, thereby reducing the overall quality and market competitiveness of chemical fiber products.

[0010] Therefore, it is necessary to improve the prior art to overcome the defects in the prior art. Utility Model Content

[0036] Example

[0037] See also Figure 1-Figure 2 As shown, a titanium dioxide homogenizing device dedicated to chemical fiber masterbatch is mainly composed of a tank body 1, a transmission shaft 2, stirring blades 3A and 3B, and a transmission component 4.

[0038] The tank body 1 is the main structure of the entire device, and its upper end is equipped with a cover plate, which provides a certain degree of sealing and protection for the inside of the device. The lower end of the tank body 1 is provided with a discharge port 11, and a solenoid valve is carefully installed at the discharge port 11. The role of this solenoid valve is crucial. It can accurately control the opening and closing of the discharge port 11, thereby realizing accurate management of the discharge of liquid materials in the tank.

[0039] A transmission shaft 2 is vertically arranged inside the tank body 1, and this transmission shaft 2 is a key component for realizing the stirring function. The transmission assembly 4 located on the cover plate is tightly connected to the upper end of the transmission shaft 2, and the transmission shaft 2 is driven to rotate stably through its driving action.

[0040] Two stirring blades 3A and 3B are spaced apart on the transmission shaft 2. It is worth noting that the two stirring blades are arranged in a unique manner, showing an inverted state, with one stirring blade 3A rotating in the left direction and the other stirring blade 3B rotating in the right direction. This unique design allows the material to be stirred more fully and comprehensively during the stirring process, greatly improving the stirring effect and uniformity.

[0041] The structural design of the transmission assembly 4 is exquisite and reasonable. Among them, the belt pulley 46 connected to the transmission shaft 2 is firmly locked on the end cover by bolts, ensuring the stability and reliability of the connection. The upper end of the transmission shaft 2 is exposed above the belt pulley 46 and is connected to the large pulley 44, realizing the effective transmission of power. On the end cover, a motor seat 41 is also provided, and a reducer 42 driven by a motor is installed on the motor seat 41. A small pulley 43 is provided on the output shaft of the reducer 42, and a V-belt 49 is provided between the large pulley 44 and the small pulley 43. Through such a transmission structure, the power generated by the motor is adjusted and decelerated by the reducer, and then transmitted to the transmission shaft 2 through the synergistic effect of the small pulley 43, the V-belt 49 and the large pulley 44, driving the stirring blade to perform efficient stirring operations.

[0042] In this embodiment, the transmission shaft 2 is centrally arranged in the tank body 1, and such a layout enables the belt pulley 46 to be centrally arranged on the end cover accordingly. The speed reducer 42 is designed to be offset, and the transmission connection between the two is achieved through a V-belt 49.

[0043] This unique design has brought significant results. Before the improvement, the original reducer needed to be repaired every two days on average. Frequent repairs not only consumed a lot of time and labor costs, but also seriously affected the normal production. After this innovative design adjustment, the reducer is now repaired once a month on average, greatly reducing the maintenance frequency of the equipment.

[0044] In the present device, the distance between the two stirring blades 3A and 3B is H, and the diameter D of the stirring blades 3A and 3B is set to 700 mm. After careful design and consideration, the distance H between the stirring blades 3A and 3B has a specific range, which is greater than the diameter D of the stirring blades and less than twice the diameter D of the stirring blades.

[0045] Such a design is of great significance. When the spacing H is within this range, the two stirring blades 3A and 3B can form a good synergistic effect during the working process. When stirring materials, the action range of the upper stirring blade can complement the action range of the lower stirring blade without excessive overlap, thereby effectively avoiding the occurrence of stirring dead angles.

[0046] For example, if the spacing H is too small, the action ranges of the two stirring blades will overlap excessively, resulting in energy waste and reduced stirring efficiency. On the contrary, if the spacing H is too large, the materials in the middle may not be fully stirred. The current design can ensure that the materials are fully and evenly stirred during the stirring process, thereby achieving a better stirring effect and providing a strong guarantee for the homogenization quality of chemical fiber masterbatch.

[0047] Preferably, the periphery of the small pulley 43, the V-belt 49 and the large pulley 44 is provided with a pulley cover 45. This pulley cover 45 is not randomly configured, but is firmly fixed on the cover plate by a pull rod 47.

[0048] The existence of the pulley cover 45 is of great significance. First, it plays a key protective role for the small pulley 43, the V-belt 49 and the large pulley 44. During the operation of the equipment, it prevents foreign debris from accidentally entering the pulley system, thereby preventing possible jams, damage or even failures.

[0049] Secondly, the pulley cover 45 can effectively reduce the risk of operators being injured by accidentally touching the high-speed pulleys and belts when operating or maintaining the equipment, and provides a reliable barrier for the personal safety of the operators.

[0050] Preferably, the motor base 41 is firmly fixed to the end cover by bolt locking, which ensures the stability of the motor base during operation. At the same time, a set screw 48 is carefully arranged on the end cover, and one end of the set screw 48 is tightly abutted against the motor base 41, further enhancing the firmness of the motor base installation.

[0051] The locking between the motor base 41 and the end cover adopts a combination of bolts, nuts, washers and square washers. Through the cooperation of the above parts, the motor base 41 on the end cover has a certain shock absorption effect.

[0052] When the motor is running, it will inevitably generate vibration. This shock absorption design can effectively absorb and buffer the vibration energy and reduce the impact of vibration on the entire equipment. For example, without a good shock absorption design, the vibration of the motor may be transmitted to other components, causing loose connections, increased noise, and even affecting the accuracy and life of the equipment. With such a shock absorption effect, the stability and reliability of the equipment operation can be guaranteed.

[0053] Preferably, a crossbeam 18 is provided on the periphery of the cover plate. This crossbeam 18 surrounds the transmission assembly 4 and encloses it.

[0054] The crossbeam 18 can provide a certain degree of protection for the transmission assembly 4. During the operation of the equipment, it can effectively prevent foreign objects from entering the transmission area, preventing foreign objects from damaging the transmission assembly or interfering with its normal operation. At the same time, the crossbeam 18 also increases the structural strength of the cover plate to a certain extent, making it more stable and reliable. For example, in a more complex working environment, the crossbeam 18 can prevent splashing materials or other objects from colliding with the transmission assembly 4, ensuring that the equipment can operate stably and continuously.

[0055] Preferably, a pad 12 is provided on the lower end surface of the tank body 1. The pad 12 is centrally arranged inside the tank body 1. The central arrangement of the pad 12 makes the bottom of the tank body 1 present a unique shape with a high middle and low sides. Such a structure is very conducive to the discharge of materials from the discharge port 11.

[0056] When the material needs to be discharged, due to the inclined structure of the bottom, the material can naturally gather to the discharge port 11 under the action of gravity, reducing the material residue at the bottom of the tank. For example, in actual production, even relatively viscous materials can be discharged smoothly with the assistance of this structure, improving the efficiency and thoroughness of material discharge.

[0057] In this embodiment, the cover plate is equipped with two feed ports 13, a dilution water port 14, and a vacuum dust removal port 15. These parts have their own functions. The feed port 13 is mainly used to put materials, the dilution water port 14 is used to add dilution liquid, and the vacuum dust removal port 15 is responsible for vacuum dust removal processing. They play an important role in different links to meet the diverse needs of the production process.

[0058] In addition, the cover plate is also provided with a manhole cover 16 and a carrier plate 17 for placing the transmission assembly 4. The manhole cover 16 provides a passage for operators to enter the interior of the tank for inspection and maintenance, which greatly facilitates the later maintenance work of the equipment.

[0059] It is worth mentioning that the two feed ports 13 are distributed on both sides of the carrier plate 17, and the lower ends of the two feed ports 13 are exposed in the tank body and tilted to one side. Through this tilted design, the direct contact between the material entering the tank body 1 and the stirring blade 3A can be effectively reduced. In the actual production process, if the material directly impacts the stirring blade 3A, it may cause uneven force on the stirring blade, affect the stirring effect, and may even cause damage to the stirring blade. This tilted feeding method allows the material to enter the tank body more smoothly, and then gradually mix evenly under the action of the stirring blade, thereby ensuring the stability and efficiency of the stirring process.

[0060] For this purpose, the titanium dioxide homogenizing device for chemical fiber masterbatch of this embodiment was tested, and the material performance analysis results are as follows:

[0061] Serial number Transmission volume / ml Water dispersibility 1 400 97.2 2 450 97.9 3 400 98.1 4 430 97.8 5 420 97.9 6 450 97.6 7 440 98.2 8 400 97.9 9 430 98.1 10 450 98.5 average value 427 97.92

[0062] Table 2: Material performance analysis after transformation

[0063] The difference in material performance before and after the transformation is shown in Table 3:

[0064]

[0065]

[0066] Table 3: Differences in material properties before and after transformation

[0067] It can be seen that compared with the prior art, the performance of the material prepared by the utility model is greatly improved, the permeability is increased by 402ml, and the water dispersibility is increased by 12.33. At the same time, the material processing time is shortened from 3h / time of the original homogenization device to the current 1.5h / time, which greatly improves the production efficiency.

[0068] The utility model adjusts the position of the reducer by clever displacement. A belt pulley is added to the original reducer position, and the impeller diameter is reasonably reduced from the original diameter of Φ800mm to Φ700mm. In addition, the rotation mode of the impeller is changed from the original single left-hand rotation to left-hand rotation.

[0069] This series of improvements has brought many benefits. First, the maintenance frequency of the reducer has been significantly reduced. The frequent maintenance work in the past is no longer a problem for production, saving a lot of valuable production time. The production process can be carried out more smoothly and efficiently, effectively improving production efficiency. Secondly, this improvement has also greatly improved the dispersibility and permeability of the output materials. Better dispersibility means that the various components in the material can be mixed more evenly, thereby ensuring the quality stability and consistency of the chemical fiber masterbatch. The increase in permeability means that the material transmission in the production process is more efficient, and more materials can be processed in the same time, further improving production capacity.

[0070] For example, in actual production, poor material dispersibility before the improvement may lead to uneven color of chemical fiber masterbatch, affecting the appearance quality of the final product. After the improvement, excellent dispersibility makes the chemical fiber masterbatch uniform in color and excellent in quality. The increase in permeability also makes it possible to complete production tasks that originally took a long time to complete in a shorter time, which has won more market opportunities for enterprises.

[0071] In summary, through these carefully designed improvement measures, not only the problem of frequent equipment maintenance was effectively solved, but also the material performance and production efficiency were significantly improved.
