Description

Technical Field

[0001] This utility model relates to the technical field, and in particular to an ultrafine powder convection homogenization device. Background Technology

[0002] In numerous industrial production fields, such as chemicals, pharmaceuticals, food, and new materials, the application of ultrafine powders is becoming increasingly widespread. Due to their unique physicochemical properties, such as large specific surface area, excellent adsorption performance, and good reactivity, ultrafine powders offer significant advantages for improving the performance and expanding the functions of related products. However, during production, storage, and transportation, ultrafine powders are highly susceptible to the effects of environmental humidity, static electricity, and the inherent characteristics of the material itself, leading to agglomeration and clumping between particles, severely compromising the uniformity and dispersibility of the powder. This not only affects the stability of subsequent processing techniques and the consistency of product quality but may also reduce production efficiency and increase production costs. Ultrafine powder convection homogenization devices are key equipment developed to address these problems.

[0003] When existing equipment is in use, its airflow injection method is often relatively simple, and it often uses a fixed jet angle. As a result, the airflow is difficult to form a comprehensive and uniform convection effect inside the equipment, resulting in many dead air areas, which affects the overall quality stability of the product and makes it inconvenient to use. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing an ultrafine powder convection homogenization device.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] Preferably, the homogenization mechanism includes an upper fixing block and a lower fixing block fixedly installed on the inner wall of the box.

One end of the homogenization tube passes through the upper fixing block. A heater and a homogenization fan are provided on the top of the mounting frame. A second connecting pipe and a third connecting pipe are provided on the homogenization fan. One end of the second connecting pipe is connected to the heater. A first connecting pipe is provided on the heater. A rotary joint is provided between one end of the first connecting pipe and one end of the homogenization tube.

[0008] Preferably, the auxiliary mechanism includes a threaded rod rotatably connected between the inner walls of both sides of the housing, a movable block threadedly connected thereto on the threaded rod, a guide rod fixedly connected between the inner walls of both sides of the housing, the guide rod passing through the movable block and slidably connected thereto, a gear fixedly installed on the outer wall of the homogenizing tube above the upper fixed block, teeth meshing with the gear on the movable block, and a servo motor fixedly installed on one outer wall of the housing.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0019] Reference Figures 1-3An ultrafine powder convection homogenization device includes a base plate 13, with two mounting brackets 12 fixedly installed on the top of the base plate 13. A housing 1 is fixedly connected between the two mounting brackets 12. A feed pipe 2 is provided on the housing 1. A homogenization mechanism is symmetrically distributed on the housing 1. The homogenization mechanism includes an upper fixing block 4 and a lower fixing block 22 fixedly installed on the inner wall of the housing 1. A homogenization pipe 15 is rotatably connected between the upper fixing block 4 and the lower fixing block 22. Multiple branch pipes 14 are provided on the homogenization pipe 15. One end of the homogenization pipe 15 passes through the upper fixing block 4. A heater 8 and a homogenization fan 10 are provided on the top of the mounting brackets 12. The upper part is provided with a second connecting pipe 9 and a third connecting pipe 11. One end of the second connecting pipe 9 is connected to the heater 8. The heater 8 is provided with a first connecting pipe 6. A rotary joint 5 is provided between one end of the first connecting pipe 6 and one end of the homogenizing pipe 15. The rotary joint 5 can maintain the sealed connection between the first connecting pipe 6 and the homogenizing pipe 15 during the swinging process of the homogenizing pipe 15, ensuring that the airflow enters the homogenizing pipe 15 stably. A partition block 3 is fixedly installed on the top of each of the two upper fixed blocks 4. Both upper fixed blocks 4 are "L" shaped. A filter screen 16 is fixedly installed between the two upper fixed blocks 4. The filter screen 16 can effectively filter impurities.

[0020] The housing 1 is equipped with two auxiliary mechanisms. The auxiliary mechanisms include a threaded rod 20 rotatably connected between the inner walls of the two sides of the housing 1, a movable block 19 threadedly connected to the threaded rod 20, a guide rod 18 fixedly connected between the inner walls of the two sides of the housing 1, the guide rod 18 passing through the movable block 19 and slidably connected to it, a gear 7 fixedly installed on the outer wall of the homogenizing tube 15 above the upper fixed block 4, a tooth 21 meshing with the gear 7 on the movable block 19, a servo motor 17 fixedly installed on one side of the outer wall of the housing 1, and one end of the threaded rod 20 passing through one side of the inner wall of the housing 1 and fixedly connected to the output shaft of the servo motor 17.

[0021] In use, the material is introduced into the housing 1 through the feed pipe 2. At the same time, the heater 8 and the homogenizing fan 10 are started. After being heated, the gas is drawn into the homogenizing pipe 15 and finally sprayed out through the branch pipe 14. Since hot air is blown in from both sides at the same time, the hot air forms convection in the housing 1. The convection hot air homogenizes the fine powder and carries away the moisture in the fine powder to prevent clumping. By starting the servo motor 17, the threaded rod 20 can be rotated clockwise and counterclockwise. When the threaded rod 20 rotates clockwise and counterclockwise, the guide rod 18 can be set to move the moving block 19 back and forth. By setting the teeth 21, the gear 7 can be rotated clockwise and counterclockwise at a certain angle, which can make the homogenizing pipe 15 swing left and right. This can expand the airflow coverage, reduce dead angles, improve the homogenization effect, and make it more practical.

[0022] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
