Description

Technical Field

[0001] This utility model relates to the field of experimental equipment technology, and in particular to a multifunctional mixing device for dispersing small amounts of powder. Background Technology

[0002] In the solid-state synthesis of catalysts, the principle is usually based on oxides or hydroxides or other metal salts. Different components are thoroughly mixed through grinding or ball milling before being synthesized via a high-temperature solid-state reaction. However, grinding or ball milling can generate trace amounts of abrasive debris that may enter the raw materials being mixed, thus affecting the final product.

[0003] Traditional dispersion mixing equipment uses V-shaped or W-shaped containers to mix different components of a sample through axial rotation, and grinding balls are added to reduce particle size and promote mixing. In this process, a single container can only handle one type of sample at a time; and due to the container volume requirements, a quantity greater than 1 kg is needed; furthermore, containers must be changed for different samples to avoid cross-contamination.

[0004] For small samples weighing less than 1 kg, the usual practice in laboratories is to put the sample into a sample bag and disperse it by constantly shaking and rotating it manually. This method is not only time-consuming and labor-intensive, but also cannot guarantee the uniformity and consistency of the sample. Utility Model Content

[0005] This invention provides a multifunctional mixing device for dispersing small amounts of powder, which solves the problem that in the prior art, a single container can only operate on one type of sample at a time.

[0006] To achieve the above objectives, the technical solution of this utility model is: a multifunctional mixing device for dispersing small amounts of powder, comprising:

[0007] The first container is hollow and strip-shaped.

[0008] A second container, wherein multiple second containers are arranged side by side inside the first container;

[0009] A limiting member is provided along the axial direction of the first container, and the limiting member abuts against the second container to restrict the movement of the second container within the shell.

[0010] Preferably, the limiting member includes a fixing rod, and the inner wall of the first container is provided with a groove along the axial direction, with the fixing rod disposed in the groove.

[0011] Preferably, the number of grooves is greater than the number of fixing rods.

[0012] Preferably, both the first container and the second container are cylindrical containers.

[0013] Preferably, the first container and the second container are perpendicular to each other.

[0014] Preferably, the first container includes a first shell and a first end cap, the first shell having openings at both ends, and the first end cap being disposed at both ends of the first shell;

[0015] The second container includes a second shell and a second end cap, the second shell having openings at both ends, and the second end cap being disposed at both ends of the second shell.

[0016] Preferably, the second container is a rigid container or a flexible container.

[0017] Compared with the prior art, the beneficial effects of this utility model are: by setting multiple second containers inside the first container and enabling the second containers to rotate synchronously with the first container, the number of samples processed at one time can be increased, improving production efficiency. The synchronous rotation of the second containers with the first container ensures the consistency of sample processing, saving labor and time costs. Only the first container, second containers, and limiting components are needed, which simplifies the equipment and saves operating space. Attached Figure Description

[0025] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0026] like Figures 1 to 4 As shown in the figure, this application provides a multifunctional mixing device for dispersing small amounts of powder, including a first container 10, a second container 20, and a limiting member 30. The second container 20 is disposed inside the first container 10, and the limiting member 30 limits the second container 20. The second container 20 contains a sample. When it is necessary to mix the sample, the first container 10 is rotated, and the second container 20 rotates synchronously under the drive of the first container 10, which can achieve the function of mixing and dispersing multiple samples at the same time.

[0027] In one embodiment, the first container 10 is strip-shaped and hollow inside. Multiple second containers 20 are installed side-by-side inside the first container 10. A limiting member 30 is arranged along the axial direction of the first container 10, and abuts against the second containers 20 to restrict their movement within the housing. It should be understood that the height of the second containers 20 is less than the inner diameter of the first container 10. This allows multiple second containers 20 to be placed sequentially inside the first container 10. The limiting member 30 is located inside the first container 10 and abuts against the upper and lower ends of the second containers 20, so that when the first container 10 moves, the second containers 20 can move synchronously with it.

[0028] By setting multiple second containers 20 within the first container 10 and enabling the second containers 20 to rotate synchronously with the first container 10, the number of samples processed at one time can be increased, improving production efficiency. The synchronous rotation of the second containers 20 with the first container 10 ensures sample processing consistency, saving labor and time costs. Only the first container 10, second containers 20, and limiting components 30 need to be set, which simplifies the equipment and saves operating space.

[0029] In one embodiment, the limiting member 30 includes a fixing rod. Multiple fixing rods are disposed within the first container 10. The inner wall of the first container 10 has an axially oriented groove 40, and the fixing rods are disposed within the groove 40. Specifically, in this application, four fixing rods are provided, arranged circumferentially along the inner wall of the first container 10. Three fixing rods are respectively provided with one groove 40, and at least one groove 40 is provided to cooperate with the fourth fixing rod. When the second container 20 uses different sizes, only the position of the fixing rods within different grooves 40 needs to be adjusted to limit the second container 20 and prevent the second container 20 from rotating relative to the first container 10.

[0030] In one embodiment, both the first container 10 and the second container 20 are cylindrical containers. The first container 10 and the second container 20 are substantially identical. The first container 10 is a large cylindrical container, and the second container 20 is a small cylindrical container; the cylindrical shape facilitates rotation and mixing of the sample. When the second container 20 is installed inside the first container 10, the first container 10 and the second container 20 are perpendicular to each other; that is, the axis of the first container 10 is perpendicular to the axis of the second container 20.

[0031] Specifically, the first container 10 includes a first shell 11 and a first end cap 12. The first shell 11 is cylindrical and open at both ends. Two first end caps 12 are disposed at both ends of the first shell 11. The first end caps 12 are used to seal the second shell. The second container 20 includes a second shell and a second end cap. The second shell is cylindrical and open at both ends. Two second end caps are disposed at both ends of the second shell. The second end caps are used to seal the second shell.

[0032] The second container 20 can be a rigid container with a certain degree of rigidity, or a flexible container filled with air and sealed (such as a PE / PP air bag). Different materials can be used according to different sample requirements.

[0033] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
