Description

Technical Field

[0001] The utility model belongs to chemical reaction equipment and relates to a stirring structure for reaction materials. Background Art

[0002] In chemical production, operations such as dissolution, preparation, dilution, and acceleration of reaction rate of materials will use a stirring mechanism. For easily soluble materials, stirring mechanical structures such as stirring paddles and rods can dissolve them in a relatively short time. However, for caked materials, granular materials, and other liquid systems that are not easy to dissolve or disperse with water, it is not easy to stir evenly and takes a long time. For some suspension systems, it is difficult to be dispersed and dissolved under the action of shear force and impact dispersion force of the stirring machinery. As a result, after long-term stirring and dissolution, and after long-term high-speed stirring and dissolution, the clarity of the solution still cannot reach the predetermined standard, and only methods such as heating up and increasing the stirring time can be used. However, for material systems with high thermal sensitivity, often only increasing the stirring time can be adopted. Obviously, this method not only increases the production time but also significantly improves the energy consumption. Content of the Utility Model

[0003] The purpose of the utility model is to provide an umbrella-shaped stirring structure for chemical reaction materials.

[0004] To achieve the above purpose, the utility model adopts the following technical solutions: An umbrella-shaped stirring structure for chemical reaction materials, in which a motor is installed on the top of the container, and the motor is directly connected or connected to the shaft rod through a transmission structure. The shaft rod extends downward into the container interior, and a number of stirring plates distributed in an umbrella-shaped manner are connected to the shaft rod. The upper part of the stirring plate is fixed to the shaft rod through an upper short rod, and the lower part of the stirring plate is fixed to the shaft rod through a lower long rod. The stirring plate is provided with a notch, and the notches form stirring teeth.

[0005] Further, a stabilizing ring is provided above the lower long rod. The stabilizing ring surrounds the shaft rod and connects the two through an inner fixing rod. An inner material plate is fixed on the stabilizing ring, and the inner material plate is inclined upward. The top of the inner material plate is fixed to the middle part of the stirring plate.

[0006] Further, the top and bottom of the stirring plate are fixed to the upper short rod and the lower long rod through U-shaped mounting plates. The end position of the stirring plate is limited within the U-shaped space of the U-shaped mounting plate, and the U-shaped mounting plate is fastened to the stirring plate through a number of fastening screws.

[0007] Preferably, the inclination angle of the stirring plate is 60 degrees.

[0008] Preferably, the spacing of the stirring teeth is 3 - 5 cm.

[0009] The utility model has the following beneficial effects: 1. The stirring plates are distributed in a ribbed umbrella shape, that is, the upper ends incline inwards and the lower ends incline outwards. The stirring surface is large, and shear force is formed at the edge part of the stirring material tooth structure. The stirring force is large. The stirring plates impact and break the material particles, and the shear force changes the single flow-around mode, thereby improving the dissolution speed.

[0010] 2. The inner material plate not only strengthens the stability of the stirring plates and reduces their deformation degree, but also disturbs the materials inside the stirring plates, further enhancing the dissolution effect of the materials that have not been fully dissolved.

[0016] As Figures 1-4 shown, a ribbed umbrella-shaped stirring structure for chemical reaction materials is installed in a container. The container is provided with a top cover or a support frame at the top for installing the motor 1. The container is provided with a feed inlet, a discharge outlet, valves, an observation window, etc., which are set according to different functions and are all prior arts. The improvement point of this solution lies in the stirring structure. The motor 1 is directly connected or connected to the shaft rod 2 through a transmission structure. The shaft rod 2 extends downward into the container interior. A plurality of stirring plates 3 distributed in a ribbed umbrella shape are connected to the shaft rod 2. The inclination angle of the stirring plates 3 is preferably 60 degrees. The upper part of the stirring plate 3 is fixed to the shaft rod 2 through the upper short rod 8, and the lower part of the stirring plate 3 is fixed to the shaft rod 2 through the lower long rod 4. The stirring plate 3 is provided with notches, and the notches form the stirring material teeth 10. The spacing between the stirring material teeth 10 is 3 - 5 cm.

[0017] In order to make the stirring plate 3 more stable when it is longer, a stabilizing ring 5 is provided above the lower long rod 4. The stabilizing ring 5 surrounds the shaft rod 2 and connects the two through the inner fixing rod 7. An inner material plate 6 is fixed on the stabilizing ring 5. The inner material plate 6 slopes upward, and the top of the inner material plate 6 is fixed to the middle of the stirring plate 3. This setting not only improves the stability of the stirring structure, but also forms agitation on the liquid material in the stirring plate 3, accelerating the dissolution or reaction speed of the material.

[0018] The top and bottom of the stirring plate 3 are fixed to the upper short rod 8 and the lower long rod 4 through the U-shaped mounting plate 9. The end position of the stirring plate 3 is limited within the U-shaped space of the U-shaped mounting plate 9. The U-shaped mounting plate 9 is fastened to the stirring plate 3 through a plurality of fastening screws. The detachable form of the U-shaped mounting plate 9 in cooperation with the fastening screws facilitates disassembly and replacement after the stirring plate 3 is deformed.

[0019] The main feature of this solution is the stirring plate distributed in the shape of umbrella ribs, which results in a large stirring surface and is suitable for occasions where the stirring force required at the bottom is greater than that required at the upper part (especially for suspended liquid materials); the edge part of the stirring teeth forms a shearing force, with a large stirring force, which can have a good impact and crushing effect on lumps and packages, refine them, change the single flow-around mode, and thus greatly improve the dissolution speed or reaction speed of the material system.
