Abstract
Description
Technical Field
[0001] This utility model relates to the field of dry material mixing technology, specifically a high-efficiency dry material mixing and stirring device. Background Technology
[0002] As is well known, traditional dry material mixing and agitation devices commonly use one or more agitators to mix dry powder materials. These devices typically include a closed mixing tank containing an agitator shaft with agitator blades mounted on it. During operation, a motor drives the agitator shaft to rotate, causing the agitator blades to mix the dry powder materials. While this design is simple in structure, it has some significant drawbacks in practical applications: after mixing, the dry powder material easily adheres to the inner wall of the mixing tank. This residue not only wastes material but, if not thoroughly cleaned, can also contaminate the next batch, affecting product quality and consistency. Furthermore, manual cleaning is required after each mixing cycle, leading to prolonged production line downtime and reduced overall production efficiency. Therefore, it is necessary to propose a solution to this technical problem. Utility Model Content

[0014] (III) Beneficial Effects
[0015] Compared with the prior art, this utility model provides a high-efficiency dry material mixing and stirring device, which has the following beneficial effects:
[0016] This high-efficiency dry material mixing device controls the up-and-down movement of the mixing motor and mixing shaft through a second lifting mechanism, so that the positioning plate on the mixing shaft can align with the positioning groove on the annular scraper. This allows the scraper to rotate and efficiently remove residual material from the inner wall of the mixing tank. After mixing, the annular scraper moves downward through the first lifting mechanism, automatically removing residual dry material from the inner wall of the tank. Traditional methods require workers to manually enter the mixing tank for cleaning, while this invention automatically completes the scraping action through a mechanical structure, greatly reducing the time and labor intensity of manual intervention and improving cleaning efficiency.
[0017] After scraping is completed, the positioning plate can be disengaged from the positioning slot by controlling the first and second lifting mechanisms to reset, which can quickly prepare for the next mixing cycle, shortening the preparation time and downtime waiting time and enhancing the continuity of production.

Detailed Implementation
[0023] 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.
[0024] Please see Figure 1-4This utility model relates to a high-efficiency dry material mixing and stirring device, comprising a mixing tank 1, a batching mechanism on the mixing tank 1, a discharge mechanism at the bottom of the mixing tank 1, a support frame 7 on one side of the mixing tank 1, a first lifting mechanism 3 on the support frame 7, a connecting plate 4 at the output end of the first lifting mechanism 3, an annular scraper 5 on the inner wall of the mixing tank 1, a bearing seat at the top of the annular scraper 5, a lifting column 6 between the bearing seat and the connecting plate 4, a slot at the top of the mixing tank 1, a support plate 2 and a second lifting mechanism 8 at the top of the mixing tank 1, a stirring motor 9 on the support plate 2, and the output end of the second lifting mechanism 8 connected to the stirring motor 9. A connecting frame 10 is provided. The output end of the stirring motor 9 passes through the slot and extends into the interior of the mixing tank 1. The output end of the stirring motor 9 is provided with a stirring shaft 11. A positioning mechanism is provided between the stirring shaft 11 and the annular scraper 5. The positioning mechanism includes a positioning plate 12, stirring blades 13, and a positioning groove 14. The positioning groove 14 is opened on the inner side of the annular scraper 5. The stirring blades 13 are mounted on the stirring shaft 11. There are multiple stirring blades 13. The positioning plate 12 connects multiple stirring blades 13. There are multiple positioning mechanisms arranged in a circular array. In this embodiment, the dry material raw materials that need to be mixed and stirred are easily supplied through the feeding mechanism, and then the output of the stirring motor 9 is used to... The end drives the stirring shaft 11 to rotate, and the stirring shaft 11 drives the stirring blades 13 and the positioning plate 12 in the positioning mechanism to stir the mixture. After the mixing is completed, the material is discharged by opening the discharge mechanism. At this time, by controlling the output end of the second lifting mechanism 8 to move the connecting frame 10 upward, the connecting frame 10 drives the stirring motor 9 and the support plate 2 to move upward. By controlling the output end of the stirring motor 9 to rotate the stirring shaft 11, the positioning plate 12 on the stirring shaft 11 can be attached to and rotated at the bottom of the annular scraper 5. When the positioning plate 12 is aligned with the positioning groove 14 opened on the inner side of the annular scraper 5, the upward force of the second lifting mechanism 8 on the stirring motor 9 can make the positioning plate 12 insert into the positioning groove 14. Through the lifting column 6 and the bearing seat, it can be... The annular scraper 5 is able to stably follow the rotation angle of the output end of the stirring motor 9. Then, the output end of the first lifting mechanism 3 is controlled to move the lifting column 6 downward. The lifting column 6 drives the annular scraper 5 to move downward through the bearing seat. The annular scraper 5 can effectively scrape off the dry material remaining on the inner wall of the mixing tank 1, so that the material remaining on the inner wall falls into the discharge mechanism and is discharged, which is convenient for the next mixing of dry material raw materials. After completion, the output end of the first lifting mechanism 3 and the output end of the second lifting mechanism 8 are controlled to reset, so that the positioning plate 12 leaves the positioning groove 14, which is convenient for the re-mixing operation. This realizes automatic and efficient scraping of the dry material remaining on the inner wall, reduces the step of manual cleaning of residues, and improves the efficiency of mixing dry materials.
[0025] In this scheme, the batching mechanism includes a batching pipe 15, which is installed on the mixing tank 1. There are multiple batching pipes 15, which can facilitate the simultaneous supply of multiple dry materials that need to be mixed.
[0026] In this solution, the discharge mechanism includes a discharge pipe 16 and a valve 17. The discharge pipe 16 is installed at the bottom of the mixing tank 1, and the valve 17 is installed on the discharge pipe 16. By opening the valve 17, the material being mixed inside the mixing tank 1 can be easily discharged. By closing the valve 17, the mixing tank 1 can easily mix the material.
[0027] In this solution, valve 17 is a solenoid valve, which allows for convenient remote operation to switch valve 17 on and off.
[0028] In this scheme, both the first lifting mechanism 3 and the second lifting mechanism 8 are electric telescopic rods. Electric telescopic rods have the characteristics of high movement accuracy and good stability, which can improve movement accuracy and facilitate the high-precision lifting and moving of the annular scraper 5 or the stirring motor 9.
[0029] In this scheme, the stirring motor 9 is a servo motor, which has the characteristics of high rotational accuracy, thereby improving the accuracy of the positioning plate 12 in aligning with the positioning groove 14.
[0030] In this scheme, there are two lifting columns 6 arranged symmetrically, which can further stabilize the lifting and lowering of the annular scraper 5.
[0031] In this scheme, the dispensing pipe 15 is provided with a flange 18, which facilitates the connection of the dispensing pipe 15 to an external feeding pipe.
