Description

Technical Field

[0001] This utility model relates to a mixing kettle structure and belongs to the field of mixing kettle technology. Background Technology

[0002] Mixing kettles are widely used in the chemical, pharmaceutical, and food industries, primarily for mixing, stirring, and reacting various materials. They are typically cylindrical and mostly made of stainless steel, offering good corrosion resistance and strength. After use, the inner wall of the mixing kettle needs to be cleaned of any remaining material.

[0003] However, the internal structure of the mixing vessel is complex, making cleaning inconvenient and leaving material residues that can affect subsequent operations. There is an urgent need for a new mixing vessel structure to address these issues. Utility Model Content

[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a mixing tank structure to solve the problems mentioned in the background technology. This utility model adopts an external gear transmission structure, which can perform rotational scraping operation without affecting the rotation of the mixing shaft, and can subsequently clean the residual material on the inner wall of the tank.

[0005] To achieve the above objectives, this utility model is implemented through the following technical solution: a mixing vessel structure, including a mixing vessel body, a mixing shaft, and an arc-shaped rotating scraper rod. A ball bearing seat is embedded in the middle of the upper end of the mixing vessel body. A fixing frame is installed on the upper end of the mixing vessel body. A mounting top plate is horizontally fixed on the upper end of the fixing frame. A mixing motor is fixed at the lower end of the mounting top plate. Multiple universal ball bearings are installed on the upper end of the mixing vessel body. A low-speed motor is fixed to the left end inside the fixing frame. A spur gear is installed on the shaft end of the low-speed motor. The ball bearing shaft... A rotating outer cylinder is fixedly inserted through the bearing seat. A stepped ceramic inner cylinder is fixed inside the rotating outer cylinder. The mixing shaft moves through the stepped ceramic inner cylinder. Multiple mixing rods are installed on the annular side of the mixing shaft. A gear disk is horizontally fixed at the upper edge of the rotating outer cylinder. The rolling ends of multiple universal balls slide against the lower end face of the gear disk. Connecting support rods are fixed on the left and right sides of the lower end of the rotating outer cylinder. Arc-shaped rotating scraping rods are symmetrically fixed at the lower ends of the two connecting support rods. The two arc-shaped rotating scraping rods slide against the left and right ends of the inner wall of the mixing vessel, respectively.

[0006] Furthermore, a discharge pipe and valve are installed at the lower end of the mixing vessel, and a feed pipe and feed valve are installed at the upper end of the mixing vessel.

[0007] Furthermore, a honeycomb perforated plate is bolted to the front end of the fixing frame.

[0008] Furthermore, the mixing motor shaft is connected to the mixing shaft via a transmission.

[0009] Furthermore, two spiral mixing blades are fixed intersectingly between the plurality of mixing rods.

[0010] Furthermore, the spur gear meshes with the gear disc for transmission.

[0011] The beneficial effects of this utility model are as follows: This utility model provides a mixing kettle structure. Because it adds a mixing motor, mixing shaft, mixing rod, spiral mixing blades, spur gear, gear disk, universal ball bearing, stepped ceramic inner cylinder, low-speed motor, rotating outer cylinder, ball bearing seat, connecting support rod, and arc-shaped rotating scraping rod, our design improvements and actual use have shown that this device has a reasonable structure, good practicality, and adopts an external gear transmission structure, which can perform rotating scraping operations without affecting the rotation of the mixing shaft. It can then clean the residual material on the inner wall of the kettle. Moreover, it is simple to operate and easy to promote and use. Attached Figure Description

Detailed Implementation

[0017] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0018] Please see Figures 1-3This utility model provides a technical solution: a mixing vessel structure, including a mixing vessel body 1, a mixing shaft 7, and an arc-shaped rotating scraper 17. A ball bearing seat 15 is embedded in the middle of the upper end of the mixing vessel body 1. A fixing frame 3 is installed on the upper end of the mixing vessel body 1. A mounting top plate 4 is horizontally fixed on the upper end of the fixing frame 3. A mixing motor 6 is fixed on the lower end of the mounting top plate 4. Multiple universal ball bearings 12 are installed on the upper end of the mixing vessel body 1. A low-speed motor 101 is fixed on the left end inside the fixing frame 3. A spur gear 10 is installed on the shaft end of the low-speed motor 101. A rotating outer cylinder 14 is fixed through the ball bearing seat 15. A step is fixed inside the rotating outer cylinder 14. A ceramic inner cylinder 13 is formed, through which a mixing shaft 7 moves. Multiple mixing rods 8 are installed on the annular side of the mixing shaft 7. A gear disk 11 is horizontally fixed at the upper edge of the rotating outer cylinder 14. The rolling ends of multiple universal balls 12 slide against the lower end face of the gear disk 11. Connecting support rods 16 are fixed on the left and right sides of the lower end of the rotating outer cylinder 14. Arc-shaped rotating scraping rods 17 are symmetrically fixed at the lower ends of the two connecting support rods 16. The two arc-shaped rotating scraping rods 17 slide against the left and right ends of the inner wall of the mixing vessel 1, respectively. This design solves the problems of complex internal structure, inconvenient cleaning, easy material residue, and impact on the next operation of the existing vessel.

[0019] As the first embodiment of this utility model: a discharge pipe and valve are installed at the lower end of the mixing vessel body 1, and a feed pipe 2 and a feed valve are installed at the upper end of the mixing vessel body 1. A honeycomb perforated plate 5 is bolted to the front end of the fixing frame 3. The honeycomb perforated plate 5 can be disassembled by bolting to the front end of the fixing frame 3 for maintenance of the internal components of the fixing frame 3. At the same time, the honeycomb perforated plate 5 facilitates heat dissipation for the mixing motor 6 and the low-speed motor 101. The shaft end of the mixing motor 6 is connected to the mixing shaft 7 for transmission. The added mixing motor 6 can drive the mixing shaft 7 to rotate. The mixing motor 6 and the low-speed motor 101 are connected to an external controller through wires. Since these are existing mature components, their working principle is known to those skilled in the art and will not be described in detail.

[0020] Two spiral mixing blades 9 are fixedly intersecting between multiple mixing rods 8. When the added multiple mixing rods 8 and the two spiral mixing blades rotate, the mixture in the mixing vessel 1 is thoroughly stirred and mixed. A spur gear 10 meshes with a gear disk 11 for transmission. When the spur gear 10 rotates, it can drive the gear disk 11 to mesh and rotate.

[0021] As a second embodiment of this utility model: the mixing motor 6 is started, which drives the mixing shaft 7, multiple mixing rods 8 and two spiral mixing blades 9 to rotate, which can fully stir and mix the materials in the mixing vessel 1. During this process, the mixing shaft 7 rotates through the stepped ceramic inner cylinder 13. When it is necessary to clean the residual materials on the inner wall of the mixing vessel 1, the low-speed motor 101 is started, which drives the spur gear 10 to rotate. When the spur gear 10 rotates, it can drive the gear disk 11 to mesh and rotate. At this time, the gear disk 11 can rotate smoothly at the rolling end of multiple universal balls 12. The rotation of the gear disk 11 can drive the rotating outer cylinder 14 to rotate in the ball bearing seat 15, and can also adjust the stepped ceramic inner cylinder 13 and the two connecting support rods 16 to rotate, thereby causing the two arc-shaped rotating scraping rods 17 to also be driven to rotate, so as to rotate and clean the residual materials on the inner wall of the mixing vessel 1.

[0022] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. It will be apparent to those skilled in the art that this utility model is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or basic characteristics of this utility model. Therefore, the embodiments should be considered exemplary and non-limiting in all respects. The scope of this utility model is defined by the appended claims rather than the foregoing description, and thus all variations falling within the meaning and scope of equivalents of the claims are intended to be included within this utility model. No reference numerals in the claims should be construed as limiting the scope of the claims.

[0023] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
