Description

Technical Field

[0001] This utility model relates to the field of chemical mixing technology, specifically a chemical mixing device. Background Technology

[0002] In chemical production, in order to process raw materials into finished products of a certain specification, it is often necessary to stir and mix multiple raw materials in order to proceed to the next process.

[0003] Some existing mixing equipment has a relatively simple structure. When mixing and processing multiple chemical raw materials, the materials are often directly put into the mixing equipment at one time and then mixed by a stirrer. However, the method of putting the materials in at one time can easily lead to the accumulation of raw materials. In particular, some solid particulate materials have a certain weight. Once they accumulate, they can easily affect the uniformity and efficiency of subsequent mixing.

[0004] To address the aforementioned problems, we propose a chemical mixing and stirring device. Utility Model Content

The stirring assembly includes a rotating shaft, which is movably installed in the middle of the inner cavity of the mixing drum. A drive motor is connected to the bottom of the rotating shaft. Spiral stirring blades are installed on the upper outer wall of the rotating shaft. A dispensing plate is disposed at the top of the rotating shaft. A feeding assembly is disposed at the top of the inner cavity of the mixing drum. The feeding assembly includes two sets of feeding channels.

During the feeding process of multiple raw materials, the materials are conveyed by a conveyor belt, which enables the initial mixing of multiple raw materials.

[0020] The technical solution in this application embodiment is to solve the problems mentioned in the background art, and the overall idea is as follows:

[0021] Example: Refer to Figure 1 - Figure 3As shown, a chemical mixing device according to this embodiment includes a mixing drum 1. A mixing assembly is provided in the middle of the inner side of the mixing drum 1. The mixing assembly includes a rotating shaft 4, which is movably installed in the middle of the inner cavity of the mixing drum 1. A drive motor 3 is connected to the bottom of the rotating shaft 4 and is fixedly installed in the middle of the bottom end of the mixing drum 1. A spiral stirring blade 5 is installed on the outer wall of the upper end of the rotating shaft 4, and a throwing plate 8 is provided on the top of the rotating shaft 4. The rotating shaft 4 is driven by the drive motor 3 to rotate, thereby driving the spiral stirring blade 5 and the throwing plate 8 to rotate synchronously. During the rotation, the spiral stirring blade 5 can turn and convey the material inside the mixing drum 1, while the throwing plate 8 can evenly throw the material that is thrown down to the surrounding area, thereby improving the uniformity of material feeding.

[0022] The mixing cylinder 1 has a feeding assembly at the top of its inner cavity. The feeding assembly includes two sets of feeding channels 9. Multiple feeding hoppers 11 are provided at the top of the feeding channels 9. A conveyor belt 10 is provided at the bottom of the feeding channels 9. Both sets of feeding channels 9 are located at the top of the inner cavity of the mixing cylinder 1 and are located on both sides of the upper end of the spreading plate 8. The inlet end of the feeding hopper 11 is located at the top of the mixing cylinder 1, and the multiple feeding hoppers 11 are installed in a straight line.

[0023] In this process, multiple raw materials are sequentially selected and fed into the corresponding hoppers 11, and then fed onto the conveyor belt 10. The first raw materials fed down will spread on the surface of the conveyor belt 10, while the materials fed in later will be piled on top, thus forming a preliminary mixture. Finally, the conveyor belt 10 feeds all the materials onto the spreading disc 8, allowing the materials to mix again. The spreading disc 8 then rotates, spreading the mixed materials in all directions, thus achieving uniform feeding and effectively avoiding the accumulation of a large amount of material in one point.

[0024] A triangular support frame 7 is fixedly installed at the upper end of the inner cavity of the mixing cylinder 1. The spreading disc 8 is rolled on the upper middle part of the triangular support frame 7 through a bearing. The top of the rotating shaft 4 is movably installed at the center of the triangular support frame 7 and passes through the triangular support frame 7 to be fixedly connected to the bottom of the spreading disc 8.

[0025] In some examples, inlet pipes 12 are provided on the upper sides of both ends of the mixing cylinder 1 for adding reagents and liquids into the mixing cylinder 1.

[0026] In some examples, the bottom of the mixing cylinder 1 is designed as a funnel structure, and a discharge pipe 6 is provided on one side of the bottom of the funnel structure. The funnel structure allows the raw materials to flow and converge to the bottom after being put into the inner cavity of the mixing cylinder 1. At this time, the drive motor 3 drives the spiral stirring blade 5 to rotate, thereby conveying the raw materials at the bottom to the top, playing a role in turning and stirring the materials, and preventing the raw materials from settling, accumulating and clumping. This effectively improves the uniformity and stirring efficiency of mixing multiple raw materials. After the raw materials have been mixed, the valve of the discharge pipe 6 is opened, and the mixed raw materials can be discharged through the discharge pipe 6.

[0027] In some examples, the bottom of the mixing cylinder 1 is equipped with multiple sets of support feet 2 for support and fixation. The support feet 2 are used to provide stable support for the mixing cylinder 1, thereby improving stability and safety during use.

[0028] In some examples, this invention is suitable for mixing and processing solid granular raw materials because it requires conveying the raw materials via the conveyor belt 10, mainly to prevent powdery raw materials from adsorbing onto the outer surface of the conveyor belt 10.

[0029] The working principle of this utility model is as follows:

[0030] When multiple chemical raw materials need to be mixed and stirred, the multiple raw materials are first fed into the feeding hopper 11 through the conveying pipe. At the same time as the multiple raw materials are fed, the conveyor belt 10 located at the bottom of the feeding channel 9 is turned on. When the multiple raw materials fall onto the conveyor belt 10, the multiple raw materials will be initially mixed. Then the raw materials are conveyed by the conveyor belt 10 and fed onto the spreading plate 8. The multiple raw materials are simultaneously fed onto the spreading plate 8 by the conveyor belts 10 on both sides of the upper end. At this time, the multiple raw materials are mixed and processed in a secondary manner.

[0031] Driven by the drive motor 3, the spreading disc 8 rotates, generating centrifugal force during its rotation, which throws the raw materials falling on the spreading disc 8 in all directions, so that multiple raw materials can be evenly thrown and fed in all directions, thereby improving the uniformity of multiple sets of raw materials being fed into the inner cavity of the mixing drum 1.

[0032] In addition, by setting the bottom of the mixing cylinder 1 as a funnel structure, when multiple raw materials are fed into the inner cavity of the mixing cylinder 1, they will converge at the funnel structure at the bottom. When the drive motor 3 drives the rotating shaft 4 to rotate, it will simultaneously drive the spiral stirring blade 5 to rotate, so that the raw materials deposited at the bottom of the inner cavity of the mixing cylinder 1 can be turned and transported upward, thereby further improving the uniformity of mixing multiple raw materials.

[0033] This utility model, by setting up a feeding component, allows for the initial mixing of multiple raw materials through the conveyor belt 10 during the feeding process. Then, the mixed raw materials are evenly fed through the rotating and spreading disc 8. Finally, the spiral stirring blade 5 is used to turn and stir the raw materials, thereby further improving the efficiency and uniformity of the mixing and processing of multiple raw materials.

[0034] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
