Description

Technical Field

[0001] The utility model relates to the field of chemical equipment, in particular to a novel anti-sedimentation auxiliary stirring device for a synthetic fiber slurry mixing tank. Background Art

[0002] In the production process of synthetic fibers, slurry mixing is a crucial step. Slurry is usually composed of a variety of raw materials with different densities and particle sizes, which need to be fully and evenly distributed throughout the mixing tank during the mixing process to ensure the quality and performance of the final product. However, traditional synthetic fiber slurry mixing tanks often face the problem of slurry sedimentation during the mixing process.

[0003] Slurry sedimentation refers to the phenomenon that due to the different densities of the components in the slurry and the influence of gravity, the components with higher density gradually settle to the bottom of the mixing tank during the mixing process, while the components with lower density float on the upper layer. This phenomenon not only destroys the uniformity of the slurry, but may also cause sediment to appear at the bottom of the mixing tank, further affecting production efficiency.

[0004] In order to solve the problem of slurry sedimentation, the traditional method is usually to improve the mixing effect of the slurry by increasing the stirring speed or extending the stirring time. However, these methods often consume a lot of energy and time, and cannot completely eliminate the phenomenon of slurry sedimentation. In addition, too high a stirring speed may also cause the slurry to produce too much foam, further affecting the quality and production efficiency of the product. Utility Model Content

[0005] 1. Technical issues to be resolved

[0006] In view of the deficiencies in the prior art, the utility model provides a novel anti-settling auxiliary stirring device for a synthetic fiber slurry mixing tank.

[0009] A stirring shaft, which is arranged at the center of the mixing tank and is driven to rotate by a motor;

[0010] A stirring blade, which is fixed on the stirring shaft and is used for basic stirring of the slurry;

[0011] Auxiliary stirring elements are arranged around the stirring shaft and at the bottom of the stirring shaft, and include a plurality of retractable stirring rods. When the stirring shaft rotates, the stirring rods are extended under the action of centrifugal force to stir the slurry near the tank wall;

[0012] A control system is used to control the rotation speed of the stirring shaft and the extension and retraction of the auxiliary stirring elements.

[0013] Preferably, an auxiliary tube is provided at the bottom of the stirring shaft, a plurality of telescopic outer tubes are provided around the sides of the auxiliary tube, a telescopic inner tube is slidably provided inside the telescopic outer tube, a cylinder is provided inside the auxiliary tube, and the output end of the cylinder is adapted to the telescopic inner tube.

[0018] Preferably again, a sealing groove is provided at the joint between the upper tube and the lower tube to match the sealing rod.

[0019] (III) Beneficial effects

[0020] Compared with the prior art, the utility model provides a novel anti-sedimentation auxiliary stirring device for a synthetic fiber slurry mixing tank, which has the following beneficial effects:

[0021] Improve mixing efficiency: The slurry is stirred by the stirring shaft set in the center of the mixing tank and the stirring blades fixed on the stirring shaft, so that the slurry forms basic flow and mixing in the tank. In addition, the setting of the auxiliary stirring element further enhances the stirring effect. When the stirring shaft rotates, the retractable stirring rod uses the centrifugal force to extend and stir the slurry near the tank wall, effectively preventing the slurry from settling near the tank wall and improving the mixing efficiency of the slurry.

[0022] Uniform mixing: Due to the design of the auxiliary stirring element, the slurry in the tank is stirred in all directions and at multiple angles, thus achieving uniform mixing of the slurry. This uniform mixing not only improves the quality of the slurry, but also contributes to the stability of the subsequent processing.

[0023] Intelligent control: Through the control system, the rotation speed of the stirring shaft and the extension and retraction degree of the auxiliary stirring element can be accurately controlled, making the stirring process more accurate and reliable. In addition, the control system also includes a controller, a display screen and control buttons, which facilitates the operator to understand and control the stirring process in real time.

[0024] Modular design: The auxiliary cylinder is installed at the bottom of the agitator shaft through a bolt structure, which is convenient for disassembly and maintenance. At the same time, the auxiliary cylinder is composed of an upper cylinder and a lower cylinder fixed and spliced ​​by bolts. This modular design allows the upper and lower cylinders to be replaced separately, reducing maintenance costs. In addition, the joint between the upper and lower cylinders is equipped with a sealing groove and a sealing rod to ensure the sealing of the auxiliary cylinder and effectively prevent slurry leakage.

[0025] Scraper design: The scrapers arranged at the bottom of the telescopic outer tube and the end side of the rod groove can scrape the telescopic inner tube and the rod during the up and down movement of the telescopic inner tube to prevent the adhesion of slurry, which may easily cause the telescopic inner tube and the rod to get stuck in the telescopic outer tube and the rod groove.

[0026] In summary, the new anti-sedimentation auxiliary stirring device for the synthetic fiber slurry mixing tank of the present invention has multiple beneficial effects such as improving mixing efficiency, achieving uniform mixing, intelligent control, modular design and scraper design, and provides an efficient, reliable and convenient solution for the mixing of synthetic fiber slurry.
