Description

Technical Field

[0001] This utility model relates to the technical field of powder vortex mixer accessories, specifically a powder container for a powder vortex mixer. Background Technology

[0002] During the grain storage and processing stages, various biochemical indicators of grain samples need to be analyzed. The initial step in this process is to pulverize the grain samples, ensuring the pulverized grain is thoroughly mixed to guarantee the reliability of subsequent test data.

[0003] Currently, most small businesses can only process powder samples by manually shaking or mixing them with ordinary stirrers. However, manual operation is prone to uneven force and mixing time, resulting in insufficient powder mixing uniformity. Ordinary stirrers lack a special mixing design for grain powders, which can easily lead to local clumping or mixing dead zones. Both of these methods directly interfere with the accuracy of subsequent test results and cannot meet the strict requirements for sample uniformity in biochemical index testing.

[0004] To solve the problem of manually shaking powder, some companies use powder mixers. However, the common problem is that the bottom of the powder container is flat. When the powder mixer rotates, only the surface of the powder in the container is mixed, resulting in severe stratification and clumping, and uneven mixing. Utility Model Content

[0005] The purpose of this invention is to provide a powder container for a powder vortex mixer. The bottom of the powder container is designed in a spiral stepped shape, which allows the powder to be mixed more evenly as the mixer rotates.

[0006] The technical solution of this utility model:

[0007] A powder container for a powder vortex mixer includes a main body, which is an open container at the top. A spiral stepped guide plate assembly is welded and fixed to the bottom of the main body. The spiral stepped guide plate assembly consists of two guide plates and two stepped plates. The two guide plates are fan-shaped and their central ends are welded together. Both guide plates are inclined. One radial side of the first guide plate is a high end, and the other radial side is a low end. The second guide plate is inclined in the opposite direction to the first guide plate. A stepped plate is welded and fixed between the radial side of the first guide plate at the high end and the radial side of the second guide plate at the low end.

[0008] The beneficial effects of this utility model are:

[0009] 1. This application combines a powder container with a powder vortex mixer to replace manual mixing, effectively solving the problems of slow manual mixing speed and uneven mixing due to inconsistent force, which affects the accuracy of test results. The mixing efficiency of this device is far higher than that of manual shaking and large powder mixers. Taking 300-500 grams of corn powder as an example, it only takes 1-3 minutes to achieve uniform mixing, while manual shaking takes 5-10 minutes and large powder mixers take about 20 minutes.

[0010] 2. The powder container of this application is equipped with a spiral stepped guide plate assembly at the bottom of the main body. When the mixer rotates and vibrates, the stepped plates and guide plates ensure that the powder is mixed without dead corners or agglomeration, achieving rapid and uniform mixing. This solves the problem of traditional vortex mixers where the material is only mixed on the surface and suffers from severe stratification due to single-layer rotation. Moreover, it eliminates the need for a stirring rod, avoiding sample contamination. Attached Figure Description

[0019] In order to solve the problems in the background art, the powder holding device for the powder vortex mixer of this application has been invented. The powder holding device is installed on the powder mixer to replace manual mixing and can mix the powder quickly and evenly.

[0020] It should be noted that in the description of this application, terms such as "inner", "outer", "upper", and "lower" that indicate direction or positional relationship are based on the direction or positional relationship shown in the accompanying drawings. This is only for the convenience of description and does not indicate or imply that the device or element must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, it should not be construed as a limitation of this application.

[0021] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0022] like Figure 1 , 2 As shown, a powder vortex mixer 100 uses a powder container 200, comprising a powder container body 1. The powder container body 1 is a container with an open top, and is a hollow cup-shaped container with a closed bottom and an open top. A spiral stepped guide plate assembly 2 is welded and fixed to the bottom inside the powder container body 1, and powder 300 is piled on the spiral stepped guide plate assembly. Preferably, the powder container body 1 has a middle diameter larger than the diameters of the upper and lower parts, i.e., a basin-shaped structure with a "big belly".

[0023] like Figure 3 As shown, the spiral stepped guide plate assembly 2 consists of two guide plates and two stepped plates. The two guide plates are fan-shaped and their central ends are welded together. Both guide plates are arranged at an angle. One radial side 22 of the first guide plate 21 is the high end, and the other radial side 22 is the low end. The second guide plate 23 has the opposite inclination direction to the first guide plate 21. That is, the radial side of the second guide plate that is on the same side as the high end of the first guide plate is the low end, and the radial side that is on the same side as the low end of the first guide plate is the high end.

[0024] like Figure 3 , 4As shown, a stepped plate 24 is welded and fixed between the radial side 22 at the high end of the first guide plate 21 and the radial side 22 at the low end of the second guide plate 23, and the stepped plate 24 is welded and fixed between the radial side 22 at the low end of the first guide plate 21 and the radial side 22 at the high end of the second guide plate 23. The first guide plate 21, the second guide plate 23, and the two stepped plates 22 are welded together to form an inclined spiral stepped guide structure. Corn powder and other materials are placed on the spiral stepped guide plate assembly and are uniformly mixed during the rotational motion.

[0025] like Figure 4 As shown, the first guide plate 21 and the second guide plate 23 are fan-shaped with the same size and shape, and the two stepped plates 24 are triangular with the same size and shape.

[0026] The first guide plate 21 and the second guide plate 23 are tilted at an angle of 20-40 degrees relative to the horizontal plane.

[0027] The angle between the lower edge of the stepped plate 24 and the first guide plate 21 or the second guide plate 23 is 102-140 degrees.

[0028] The working principle of the powder container device for the powder vortex mixer of this application is as follows:

[0029] like Figure 5 As shown, the powder vortex mixer operates through a combination of "non-uniform circular rotation and slight vibration." During operation, the powder container of this application moves at high speed under the drive of the vortex mixer.

[0030] The rotational force drives the powder particles to move in a circular motion, and friction and collision between the particles generate fluid, thus achieving initial dispersion.

[0031] Both the first and second guide plates are arranged in an inclined spiral. The inclined surface makes it easier for the powder to slide and tumble during rotation, reducing local accumulation caused by gravity. The inclined bottom surface combined with the rotational motion forms a compound stirring, increasing the friction between the powder and the cylinder wall and promoting tumbling and mixing. The inclined structure avoids the formation of dead corners at the bottom, ensuring uniform mixing and promoting thorough mixing and even distribution of the powder. While the inclined surface guides the powder in a circular motion, it also moves laterally along the inclined spiral angle of the first and second guide plates, generating shear force and initially breaking up powder stratification.

[0032] The diameter of the middle part of the powder container is larger than that of the bottom part. When the powder, such as grain, flows to the side wall of the powder container, it makes an arc-shaped movement from bottom to top. The powder is thrown and turned over. During this process, the powder collides with each other and with the side wall of the main body, thus changing the flow path.

[0033] Two stepped plates, along with the first and second guide plates, form a spiral stepped shape. Powder encountering these plates moves upwards or downwards. This spiral stepped structure guides the powder to form a dynamic flow path within the container, preventing localized accumulation or clumping, allowing for more thorough dispersion and contact during mixing, thus enhancing mixing efficiency. The inclined stepped plates push and accelerate the powder's movement, increasing shear force to further break down powder layers and crush large clumps. Compared to traditional stirring methods, this spiral stepped structure achieves mixing through the container's own movement, reducing wear and energy consumption of mechanical stirring components and lowering overall energy consumption. The spiral flow guided by the steps creates a multi-directional circulation of powder within the container, shortening mixing time and reducing dead zones, making it particularly suitable for high-precision mixing requirements and improving mixing uniformity. Slight vibrations of the powder mixer loosen clumps of powder (such as agglomerated grain powder particles), allowing fine particles to fully fill the gaps, ultimately achieving a "no dead zones, high uniformity" mixing effect.

[0034] The present invention and its embodiments have been described above illustratively. This description is not restrictive, and the figures shown are only one embodiment of the present invention; the actual structure is not limited thereto. Therefore, if those skilled in the art, inspired by this description, design similar structures and implementations to the above embodiments without departing from the technical essence of the present invention, such designs should fall within the protection scope of the present invention.
