[0002] In industries such as chemical, pharmaceutical, and food, glass-lined agitators are widely used in processes such as material mixing, reaction, and dispersion due to their excellent corrosion resistance and stable chemical properties. As the core agitator component, the agitator shaft assembly is directly related to the operating efficiency and reliability of the equipment.
[0003] Traditional glass-lined agitators typically use bolt-fixed agitator shaft assemblies, which are assembled by welding, keying, or fastening with multiple sets of bolts to the agitator shaft and blades.
[0004] The disassembly and assembly process of traditional mixing shaft assemblies is extremely cumbersome. When maintaining the equipment or replacing the blades, operators need to use a variety of tools to disassemble a large number of connecting bolts one by one. These bolts are often distributed in different positions on the mixing shaft, and some bolts are prone to corrosion and jamming due to long-term exposure to complex working conditions, which greatly increases the difficulty of disassembly. In some large mixing equipment, due to the large size and heavy weight of the mixing shaft, hoisting equipment is also required for disassembly. The entire disassembly and assembly process is time-consuming and labor-intensive, which seriously affects the efficiency of equipment shutdown and maintenance. Utility Model Content

This solves the problem that operators need to use multiple tools to disassemble a large number of connecting bolts one by one. These bolts are often distributed in different positions on the agitator shaft, and some bolts are prone to corrosion and jamming due to long-term exposure to complex working conditions, which greatly increases the difficulty of disassembly. In some large agitator equipment, due to the large size and heavy weight of the agitator shaft, hoisting equipment is also required for disassembly.

[0020] In the description of this utility model, unless otherwise explicitly defined, terms such as "setting," "installation," and "connection" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this utility model in conjunction with the specific content of the technical solution.
[0021] Example 1: Reference Figure 1-4A typical example of a material mixing system (positioning slider + ordinary protective shell). This embodiment is applicable to the stirring of materials with ordinary viscosity (such as food sauces and low-concentration solutions). By combining the positioning slider with the basic protective shell, the blades can be stably installed and easily disassembled, meeting the needs of daily production. Structural fit and operation process: The positioning component 11 adopts a positioning slider (Q235 steel material, surface hard chrome plated), which slides with the positioning sliding groove 12 (gap ≤0.3mm) to ensure accurate guidance when the connecting seat 3 is installed. The limit block 13 is made of 45# steel. The adjusting threaded rod 15 and the rotating threaded rod sleeve 2 adopt trapezoidal threads (pitch 4mm), with a rotational torque ≤15N・m. The protective shell 7 is made of ordinary carbon steel, which serves to prevent dust and protect the rotating threaded rod sleeve 2. When disassembling the blade, use a wrench to rotate the threaded rod sleeve 2 (rotate 1.5 turns), which will drive the adjusting threaded rod 15 to push the limit block 13 out of the second limit block groove 14 (stroke 10mm). At this time, the connecting seat 3 loses its limit and is pulled out along the sliding block groove 16 (time ≤40 seconds). When installing, the operation is reversed. The positioning slider guides the connecting seat to be positioned quickly. When the blade rotates, the positioning accuracy is ≤±0.5mm, and the single stirring volume can reach 30L.
[0022] Application effects: Suitable for small and medium-sized food and chemical enterprises. The blades can be disassembled more than 300 times, improving production change efficiency by 50% and meeting the mixing needs of conventional materials.
[0023] Example 2: Reference Figure 5 Example of anti-sticking stirring for high-viscosity materials (magnetic positioning block + anti-stick coating protective shell) This embodiment is designed for stirring high-viscosity materials (such as syrup and resin). It enhances the initial positioning stability by using a magnetic positioning block and is equipped with a non-stick coating protective shell to reduce material adhesion.
[0024] Anti-stick structure optimization: Positioning component 11 is replaced with magnetic positioning block 17 (neodymium iron boron magnet, adsorption force ≥30N), which forms a pre-fixed position with the magnetic seat in the positioning sliding groove 12 to prevent the blade from shaking when stirring high viscosity materials. The protective shell 7 is coated with polytetrafluoroethylene (PTFE) anti-stick coating (thickness 0.1mm, contact angle ≥115°), and the surface of the limiting block 13 is also covered with an anti-stick film. When stirring high-viscosity materials, the magnetic positioning block automatically aligns the blades with the slide groove (deviation ≤0.2mm). The anti-stick coating makes it difficult for materials to adhere to the surface of the protective shell. When cleaning, only water rinsing is needed to remove residual materials. When disassembling, the magnetic suction seat must be demagnetized first (with the help of a demagnetizer), and then the threaded rod sleeve must be rotated. The time for changing blades once is shortened to 20 seconds, and the stirring efficiency is increased to 40L / h. High viscosity scenarios: Suitable for paint and adhesive manufacturers, improving equipment stability by 60% and reducing blade cleaning time by 70%.
[0025] Furthermore, when using this device, when it is necessary to connect the blade assembly to the mounting base 1, first align the sliding block 10 on the connecting base 3 with the sliding block groove 16 of the mounting base 1, so that the positioning element 11 (positioning slider or magnetic positioning block 17) is embedded in the positioning sliding groove 12, and push the sliding block 10 to the installation position along the groove. Then rotate the rotating threaded rod sleeves 2 on both sides. Since the adjusting threaded rod 15 is threadedly engaged with the rotating threaded rod sleeve 2, the rotation of the rotating threaded rod sleeve 2 drives the adjusting threaded rod 15 to move axially, pushing the limiting block 13 from the second limiting block groove 14 into the first limiting block groove 9 of the sliding block 10, thereby achieving rigid locking of the sliding block 10 and preventing it from loosening during operation. Then, if the magnetic positioning block 17 is used, during the sliding process, the magnetic block and the positioning block 17 will lock together. The magnetic seat in the sliding groove 12 automatically adsorbs, further enhancing the pre-fixing effect and assisting the precise insertion of the limiting block 13. When disassembling, the rotating threaded rod sleeves 2 on both sides are rotated in the opposite direction, and the threaded rod 15 is adjusted to drive the limiting block 13 out from the first limiting block groove 9 to the second limiting block groove 14, releasing the lock on the sliding block 10. If the blade 5 needs to be replaced, the fixing bolt 8 on the fixing seat 4 is unscrewed, and the rotating rod 6 can be separated from the connecting seat 3 for individual replacement or maintenance of the blade assembly. In this way, during the stirring operation, the cooperation between the positioning part 11 and the positioning sliding groove 12 restricts the lateral sway of the sliding block 10, and the engagement between the limiting block 13 and the first limiting block groove 9 prevents the longitudinal displacement of the sliding block 10. The double constraint ensures the rigid connection between the connecting seat 3 and the mounting seat 1.
[0026] By using the cooperative design of the sliding block 10 and the sliding block groove 16 in the installation component, and the linkage structure of the limit block 13 and the adjusting threaded rod 15, the traditional multi-bolt fixing method is replaced. When the equipment is maintained or the blade is replaced, the operator only needs to rotate the threaded rod sleeve 2 to adjust the threaded rod 15 to drive the limit block 13 to extend and retract, so as to realize the quick locking and separation of the connecting seat 3 and the mounting seat 1. There is no need to disassemble a large number of bolts, the disassembly and assembly process is simplified, and there is no need to use hoisting equipment to assist, which greatly shortens the downtime for maintenance and significantly improves the operating efficiency of the equipment.
[0027] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
