Description

Technical Field

[0001] This utility model relates to the field of agitators, and in particular to an adjustable bottom bearing for agitators. Background Technology

[0002] Agitators are typical mixing equipment, mainly used for mixing various liquids. Different types of agitators can achieve different effects. Choosing the right agitator can achieve good mixing and homogenization. Propeller agitators are a widely used axial-flow high-performance agitators with good discharge performance, low shear force, and a convective circulation state at low speeds and a turbulent state at high speeds. The large blade tilt angle and blade torsion allow the agitator to achieve a high flow field even in transitional or turbulent flow. Its discharge capacity is 30% higher than that of traditional propeller agitators. It is suitable for mixing, dissolving, solid suspension, heat transfer, reaction mass transfer, extraction, and crystallization operations with low viscosity. Turbine agitators (also known as turbine impellers) are a widely used type of agitator that can effectively complete almost all mixing operations and can handle fluids with a wide viscosity range.

[0003] Currently, mixers are very important in mixing products. Existing mixers are basically installed with a fixed bottom bearing. While this installation method is stable, it results in uneven mixing. If corners need to be mixed, workers need to move the mixer by hand to achieve irregular mixing, which increases the workload of workers and reduces mixing efficiency. To address these issues, we propose a mixer with an adjustable bottom bearing. Utility Model Content

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Please see Figure 1-4 In this utility model, an adjustable bottom bearing for a mixer includes a mounting frame 1. An adjustment hole 18 is provided on the bottom surface of the mounting frame 1. Two positioning plates 2 are fixedly connected to the upper surface of the mounting frame 1. Electric push rods 3 are fixedly embedded on the sides of the two positioning plates 2 that are close to each other. A bottom bearing shaft 4 is fixedly mounted on the ends of the two electric push rods 3 that are close to each other. A rotary motor 5 is fixedly connected to the inner ring of the bottom bearing shaft 4. A slide rail 6 is fixedly connected to the inner top wall of the mounting frame 1. A slider 20 is slidably connected to the inner wall of the slide rail 6. The bottom surface of the slider 20 is flush with the rotary motor 5. The upper surface is fixedly connected, and the bottom surface of the bottom bearing shaft 4 is fixedly connected to a U-shaped fixing frame 7. The inner ring of the U-shaped fixing frame 7 is hinged to a stirring rod 8 through a pin. The bottom end of the stirring rod 8 is fixedly connected to a set of stirring frames 9. By using the pushing force of the electric push rod 3, and in conjunction with the sliding connection between the slide rail 6 and the slider 20, the position of the bottom bearing shaft 4 can be easily adjusted. In addition, the rotation of the rotating motor 5 can drive the stirring rod 8 and the stirring frames 9 to stir. At the same time, the displacement of the bottom bearing shaft 4 can make the stirring rod 8 and the stirring frames 9 stir irregularly, which improves the quality of stirring.

[0021] A handle 15 is fixedly connected to the upper surface of the mounting frame 1. The outer surface of the handle 15 has anti-slip texture. The handle 15 and anti-slip texture make it easy to grip the equipment during operation, improving the mixing quality and preventing it from slipping out of the hand. A set of heat dissipation holes 16 are provided on the outer surface of the mounting frame 1. A ring-shaped reflective sticker 17 is attached to the outer surface of the mounting frame 1. The heat dissipation holes 16 and the ring-shaped reflective sticker 17 facilitate heat dissipation for the rotating motor 5, protect the rotating motor 5, and easily indicate the location of the equipment to surrounding personnel, making it easier for them to find and improving its visibility. A U-shaped limiting frame 10 is fixedly connected to the bottom surface of the mounting frame 1. The bottom surface of the U-shaped limiting frame 10 has a limiting opening 11. The U-shaped limiting frame 10 and the limiting opening 11 can assist in limiting the swing position of the stirring rod 8, preventing it from swinging too much and affecting safety, thus improving the safety of the operator.

[0022] Two screw holes 12 are provided on the outer surface of the U-shaped limit bracket 10. Two threaded seats 13 are provided on the outside of the U-shaped limit bracket 10. Each threaded seat 13 has a support handle 14 fixedly connected to its outer surface. The screw holes 12, threaded seats 13 and support handles 14 provide users with two different ways of picking up the device and improve the fixing effect when picking it up. Two reinforcing blocks 19 are fixedly connected to the inner side wall of the U-shaped limit bracket 10. The upper surface of each reinforcing block 19 is fixedly connected to the bottom surface of the mounting bracket 1. The reinforcing blocks 19 can improve the stability of the U-shaped limit bracket 10 and prevent the U-shaped limit bracket 10 from loosening when subjected to large forces, thereby improving its service life.

[0023] The working principle of this utility model is as follows:

[0024] First, connect the threaded seat 13 to the threaded hole 12 to install the support handle 14, connect the electrical components to the power supply, and start the rotating motor 5 to drive the stirring rod 8 and the stirring frame 9 to stir the material to be stirred. At the same time, as needed, start the electric push rod 3 in conjunction with the slide 6 and the slider 20 to push the bottom bearing shaft 4 for fine adjustment. The fine adjustment of the bottom bearing shaft 4 can make the stirring rod 8 and the stirring frame 9 swing irregularly to stir, which improves the stirring quality. The above is the complete usage process of this utility model.
