Abstract
Description
Technical Field
[0001] The present invention relates to the field of experimental equipment, and particularly to a raw material mixing device for experiments. Background Art
[0002] In the working environment of a materials science laboratory, experimental operations based on mixing materials are often carried out. For some specific disciplines, solid powders are often used as experimental raw materials in experiments. Due to the physical properties of solid powders being different from those of liquids, there is a series of mixing devices applied to solid powder materials in the prior art.
[0003] In the prior art, a drum mixer is a common device for mixing solid powder materials. After the materials to be mixed are put into the drum part from the feeding port, the drum part rotates around the horizontal axis. The materials will form a material slope at the inner bottom of the drum part. As the drum part rolls, the materials on the surface and at the bottom of the slope will slide and move, thereby gradually mixing the material powders.
[0004] However, there are some problems when using such devices. For some materials whose fine particles are prone to adsorb or agglomerate with each other, especially polymer materials, during the mixing process, fine particle clusters that are difficult to disassemble and are adsorbed together will be formed. Larger-sized drum parts need to be used to form a higher slope, increasing the kinetic energy generated by the sliding of the fine particles and the shear force between them to solve the above problems. However, for the research environment of disciplines such as polymer materials science, it is difficult to achieve a large-sized drum part in a laboratory environment. Therefore, a device is needed to solve the problem of poor mixing effect of small-sized drum parts caused by particle adsorption and agglomeration. Summary of the Invention

DETAILED DESCRIPTION
[0027] The following is a detailed description of the specific embodiments of the present invention, but it should be understood that the protection scope of the present invention is not limited by the specific embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the protection scope of the present invention.
[0028] An experimental raw material mixing device provided by the present invention includes a drum member 1, a feeding assembly 3, a rotating member 4, etc. The drum member 1 is configured to rotate around a horizontal axis. An inlet channel 14 is provided on the drum member 1, and a closing member 2 is detachably connected in the inlet channel 14 to close the inlet channel 14. The material powder enters the drum member 1 from the inlet channel 14 and forms a material heap slope at the bottom of the drum member 1. The feeding assembly 3 includes a first jet member 31 and a feeding pipe 32. One end of the feeding pipe 32 is detachably connected to the inlet channel 14 of the drum member 1, and the other end of the feeding pipe 32 is connected to the first jet member 31. An inlet is provided on the side wall of the feeding pipe 32. A movable member 321 is movably connected to the feeding pipe 32. The movable member 321 is configured to be able to close / open the inlet. The first jet member 31 is configured to be able to generate an air flow to blow the material powder in the feeding pipe 32 into the drum member 1 from the inlet channel 14. The rotating member 4 is rotatably connected to the inside of the drum member 1. The rotating member 4 is used to rotate inside the drum member 1 to generate a stirring air flow. There is a gap between the rotating member 4 and the material heap slope.
[0029] Specifically, please refer to Figures 1 - 5 , during use, the feeding pipe 32 is connected to the inlet channel 14, and then the material powder to be mixed is put into the feeding pipe 32 from the inlet. Then, the movable member 321 is used to close the inlet. The first jet member 31 is used to generate an air flow to blow the material powder in the feeding pipe 32 into the drum member 1 from the inlet channel 14. Driven by the air flow, the material powder will be lifted into the inside of the drum member 1. At the same time, the rotating member 4 rotates to generate a stirring air flow. Based on the relative speed between the air flow generated by the first jet member 31 and the stirring air flow, collisions will occur between particles, between the particles and the rotating member 4, and between the particles and the inner wall of the drum member 1. The particles that are prone to agglomeration will be sheared by the collision, friction, and air flow impact and dispersed. Then, they will be stirred and mixed in the air by the air flow generated by the first jet member 31 and the stirring air flow, thereby performing a preliminary mixing process on the material powder. During this process, the material powder that has undergone the above process will finally be deposited at the inner bottom end of the drum member 1 to form a material heap slope. At this time, starting the rotation of the drum member 1 can perform subsequent mixing processing on the material powder, solving the technical problem that when a drum mixer is applied to a laboratory, due to limited size, its mixing effect is poor and it is difficult to handle adsorbed and agglomerated particles, thus achieving beneficial effects.
[0030] In various embodiments, the gas used by the first jet member 31 to generate the airflow can be any gas known to those skilled in the art that will not affect the mixed material, and those skilled in the art can flexibly adjust the gas type according to requirements to adapt to the experimental needs. For example, when the material is an easily oxidizable substance, an inert gas is used, while when the material is relatively inert and has no special requirements for the gas atmosphere, air can be used to reduce the experimental cost. Similarly, the rotation speeds of the roller member 1 and the rotating member 4, as well as the airflow speed generated by the first jet member 31, can also be flexibly adjusted by those skilled in the art according to the specific experimental requirements to avoid the heat generated by friction and movement from affecting sensitive materials, and at the same time, the operating power can be increased to improve the mixing efficiency and effect when conditions permit.
[0031] Further, considering that, for example, some easily adsorbed particles such as certain polymer materials are likely to deposit on the inner sidewall of the roller member 1 after being lifted, in order to increase the raw material utilization rate and reduce the problem that the raw materials adhere to the inner wall of the roller member 1 during the mixing process and are not mixed into the heap slope, resulting in an error in the mixing product ratio, specifically, it further includes: a scraping member 5, the scraping member 5 is connected to the rotating member 4, the scraping member 5 abuts against the inner sidewall of the roller member 1, the rotation of the rotating member 4 can drive the scraping member 5 to rotate together, and the scraping member 5 is configured to be able to scrape the material powder on the inner sidewall of the roller member 1 during rotation.
