Description

Technical Field

[0001] The utility model belongs to the technical field of premixes, and in particular relates to a premix device. Background Art

[0002] Mixing is a processing step that is often required in the production process. Specifically, during the production and processing of biological preparations, microorganisms and their metabolites such as lactic acid bacteria and Bacillus licheniformis are mixed into the main ingredients such as powder. After sufficient mixing and seasoning, subsequent processing including drying and screening is carried out to obtain biological preparations that can be used directly, such as breeding aids often used in aquaculture.

[0003] In the mixing production process, auxiliary materials including microorganisms and their metabolites are mixed into the main material. During the mixing process, when the microbial liquid is added to the powder main material, the microbial liquid contains not only microorganisms and metabolites but also liquid culture medium. Therefore, during the mixing process, especially in the initial stage of mixing, the main material is easily adhered to the stirring device of the mixing equipment, such as the stirring paddle, due to the increase in humidity. After adhesion, the stirring paddle cannot remove the adhered material, resulting in the stirring device rotating for a period of time and wrapping up the last material, which leads to insufficient mixing, increased stirring resistance, and the inability of the material adhered to the stirring paddle to fully participate in the mixing.

[0039] Example 1

[0040] like Figure 1-5 As shown, a premixing device includes a mixing barrel 1, in which a mixing mechanism is installed (material is added from the barrel opening of the mixing barrel 1 and from the gap between the mixing mechanism and the mixing barrel 1). Specifically, the mixing mechanism includes an upper connecting frame 22 and a lower connecting frame 23 spaced apart from each other. The upper connecting frame 22 and the lower connecting frame 23 have a cross-shaped transverse cross-section and have four connecting ends.

[0041] At the same time, in order to reduce the resistance during the rotation process, the lower connecting frame 23 is provided with a plurality of lower roller mounting openings, in which lower rollers 231 are mounted that roll at the bottom of the mixing barrel 1. By supporting the rolling method, the load on the rotating mixer is reduced when a large amount of material adheres to the long mixing plate during the mixing process.

[0042] Specifically, a plurality of long mixing plates 24 are fixedly installed between the upper connecting frame 22 and the lower connecting frame 23; the top and bottom of the long mixing plates 24 are respectively fixedly connected with mounting screws, and the mounting screws are fastened to the connecting ends.

[0043] At the same time, the above-mentioned mixing mechanism also includes a scraping mechanism slidably mounted on the long mixing plate 24 for scraping the material adhered to the long mixing plate 24. The scraping mechanism includes a U-shaped seat 26 slidably connected to the long mixing plate 24, and the bottom of the U-shaped seat 26 is fixedly connected to a scraping plate 27 (the sliding method is: the top of the U-shaped seat 26 and the bottom of the scraping plate 27 are respectively provided with sliding openings for sliding connection to the long mixing plate 24), and the scraping plate 27 is slidably connected to the long mixing plate 24.

[0044] The pushing and scraping mechanism further includes a pushing cylinder 25 mounted on the upper connecting frame 22, the piston rod of the pushing cylinder 25 being fixedly mounted on the top of the pushing and scraping plate 27; the U-shaped seat 26 and the long mixing plate 24 are elastically slidably connected via a spring structure.

[0045] During the working process, when too much material adheres to the long mixing plate 24, resulting in insufficient mixing of the material, the pushing and scraping mechanism can remove the adhered material.

[0046] Specifically, a long rectangular slide 241 is provided on the long mixing plate 24, and a vertically arranged spring slide rod 243 is fixedly connected inside the long rectangular slide 241. A horizontal slide rod 261 passing through the long rectangular slide 241 is fixedly connected between the two sides of the U-shaped seat 26, and the spring slide rod 243 is vertically slidably connected to the horizontal slide rod 261; a spring 242 is sleeved on the spring slide rod 243, and the two ends of the spring 242 are respectively fixedly connected to the upper end of the long rectangular slide 241 and the top position of the horizontal slide rod 261.

[0047] During operation, when too much material adheres to the long mixing plate 24, resulting in insufficient mixing, the operator activates the push cylinder 25. Driven by the push cylinder 25, the push scraper 27 and the U-shaped seat 26 slide vertically on the long mixing plate 24. During this operation, the push scraper 27 removes the adhered material from the long mixing plate 24.

[0048] During this process, the horizontal sliding rod 261 slides vertically in the long rectangular sliding mouth 241, and at the same time, the spring 242 is stretched. When the material stripping is completed, the scraper 27 and the U-shaped seat 26 are reset with the assistance of the restoring force of the spring 242, and the material stripping continues when the adhered material increases again.

[0049] The above device can mix the materials while working, and when the materials adhere to the stirring structure during the mixing process, the adhered materials can be removed to facilitate the materials to participate in the mixing, improve the adequacy of the mixing, and at the same time reduce the workload of the stirring rotation.

[0050] A rotary motor 21 for rotating and mixing materials is mounted on the top of the upper connecting frame 22 (the rotary motor 21 is a forward and reverse motor that cooperates with the operation of the cylinder). Specifically, a connecting shaft is fixedly connected to the top center of the upper connecting frame 22, and the connecting shaft is fixedly mounted on the output shaft of the rotary motor 21 via a flange.

[0051] At the same time, the motor is fixedly installed in accordance with the existing method. Specifically, in the same manner as in the existing method, a motor mounting frame (not shown in the figure) is fixedly installed on the top of the rotating motor 21 of the motor. The motor mounting frame can adopt a mounting frame such as a U-shaped structure and be fixedly installed to the outer wall of the mixing barrel 1.

[0052] Example 2

[0053] like Figure 1-5 As shown, this embodiment builds on the structure of Example 1. To further reduce the workload of the rotary mixer during operation, increase the flexibility of the rotation, and address the problem of excessive load on the rotary mixer caused by material adhering to the mixing plate, the barrel of the push cylinder 25 is fixedly mounted on the connecting end of the upper connecting frame 22. Furthermore, a circular track is fixedly connected to the mouth of the mixing barrel 1; the barrels of the push cylinders 25 roll on the top of the circular track via a rolling structure.

[0054] Specifically, the rolling mechanism includes a rolling frame 32 fixedly connected to the top of the cylinder barrel of the push cylinder 25. The lower end of the rolling frame 32 is mounted with a roller 321 that rolls on the top of the circular track. An annular connecting plate 33 is fixedly mounted at the top of the rolling frame 32 and fastened to the rolling frame 32 via bolts. The rotating motor 21 passes through the center of the annular connecting plate 33.

[0055] During the working process, the cylinder follows the rotation (the rotation mode is forward and reverse, and the pump air hose installed on the cylinder has a certain degree of freedom and does not affect the operation of the cylinder). Therefore, the roller frame 32, roller, and annular connecting plate 33 structure support the rolling rotation from the upper end position, thereby supporting the rolling rotation and greatly improving the flexibility of mixing.

[0056] Example 3

[0057] like Figure 1-5As shown, this embodiment builds on the structure of Example 1. To discharge the materials after mixing is completed during operation, a discharge structure is provided at the bottom of the mixing barrel 1 according to existing methods. The discharge structure includes a discharge plug seat A threadedly connected to the bottom of the mixing barrel 1 (a driving handle is mounted on the discharge plug seat A). The bottom of the mixing barrel 1 is provided with a plug hole threadedly connected to the discharge plug seat A. Rotating the driving handle opens the discharge plug seat A to discharge the mixed materials.

[0058] Of course, the above description is not a limitation of the present invention, and the present invention is not limited to the above examples. Changes, modifications, additions or substitutions made by technicians in this technical field within the essential scope of the present invention should also fall within the scope of protection of the present invention.
