Description

Technical Field

[0001] This utility model belongs to the field of material mixing technology, and specifically relates to a raw material mixing device. Background Technology

[0002] Raw material mixing is a crucial basic process in industrial production, widely used in industries such as chemical, pharmaceutical, food, plastics, and metallurgy. Its core purpose is to use mechanical force, airflow, or other energy methods to achieve a highly uniform spatial distribution of two or more raw materials with different properties, thereby obtaining a mixture or intermediate product with consistent composition and stable performance.

[0003] High-pressure gas-assisted mixing is an advanced mixing technology that cleverly utilizes high-pressure gas as an energy carrier and medium to overcome some limitations of traditional mechanical mixing. Its working principle does not rely on direct agitation by mechanical components, but rather on injecting high-pressure gas instantaneously or in pulses into the powder bed through a special gas distribution plate or nozzle pre-designed at the bottom of the mixing container.

[0004] Traditional gas mixing devices use longer pipelines to increase mixing time for more thorough mixing. However, longer pipelines require more gas input pipes, and these pipelines are difficult to maintain. Therefore, there is a need to develop a raw material mixing device that is easy to clean and maintain. Summary of the Invention

[0005] The purpose of this invention is to address the aforementioned problems in the existing technology by providing a gas-assisted mixing and cleaning device for raw material mixing that is simple to use.

[0006] The objective of this utility model can be achieved through the following technical solution: A raw material mixing device, characterized in that it includes a mixing channel with an inlet and an outlet, the mixing channel being stepped, and having several arc-shaped passages on both sides, both ends of which are connected to the mixing channel, a partition cavity being provided between the arc-shaped passages and the mixing channel, several injection pipes and air injection pipes being provided on both sides of the mixing channel, a cover being provided on the mixing channel, a support tray being provided at the bottom of the mixing channel, and an insulation cover being provided on the cover, the insulation cover abutting against the support tray.

[0007] In the above-mentioned raw material mixing device, the inner wall of the partition cavity is provided with several spokes, the support tray is provided with several heating blocks, and the heating blocks are placed inside the partition cavity.

[0008] In the above-mentioned raw material mixing device, the partition chamber and the side wall of the mixing channel are provided with sealing strips.

[0009] In the aforementioned raw material mixing device, the heat-insulating cover is provided with several handles.

[0010] Compared with existing technologies, this raw material mixing device designs the mixing channel as a Tesla valve, which uses gas to carry the raw materials forward and the materials collide through the pipeline, increasing the fusion of the materials. The spokes receive the temperature of the heating block, which increases the adaptability of this mixing device and allows materials that need to be heated to be mixed at a more suitable temperature.

Detailed Implementation

[0016] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0017] like Figures 1-4As shown, this raw material mixing device includes a mixing channel 6 with an inlet 1 and an outlet 3. The mixing channel 6 is stepped, and several arc-shaped passages 14 are provided on both sides of the mixing channel 6. Both ends of the arc-shaped passages 14 are connected to the mixing channel 6. A partition cavity 9 is provided between the arc-shaped passages 14 and the mixing channel 6. Several injection pipes 13 and air injection pipes 10 are respectively provided on both sides of the mixing channel 6. A cover 5 is provided on the mixing channel 6, and a support tray 7 is provided at the bottom of the mixing channel 6. An insulation cover 2 is provided on the cover 5, and the insulation cover 2 abuts against the support tray 7. The material enters through the inlet 1, and high-pressure gas carries the raw material towards the support tray 7. In the control system, part of the raw material moves forward along the stepped mixing channel 6, while another part enters the annular channel and then flows back into the wedding channel. Through the collision of the two sets of materials, the mixing of the materials is more thorough. The gas injection pipe 10 is set parallel to the mixing channel 6. When the gas carries the materials and they collide and mix, some of the kinetic energy of the high-pressure gas is lost. Gas is injected through the remaining gas injection pipes 10 to ensure the kinetic energy of the material flow. The outlet of the injection pipe 13 is aligned with the junction of the mixing channel 6 and the arc-shaped passage 14. The proportion of each material is judged by the detection of the material at the outlet 3. If the proportion of the detected materials is incorrect, different materials are delivered through different injection pipes 13 to make the discharged material meet the production requirements.

[0018] Preferably, the inner wall of the partition cavity 9 is provided with a number of spokes 11, and the tray 7 is provided with a number of heating blocks 8. The heating blocks 8 are placed in the partition cavity 9. The heating blocks 8 heat up, and the cover plate absorbs the heat and transfers it to the mixing channel 6, so that some materials that need to be temperature controlled can maintain a suitable processing temperature.

[0019] Preferably, sealing strips 12 are provided on the side walls of the partition cavity 9 and the mixing channel 6.

[0020] Preferably, the heat-insulating cover 2 is provided with several handles 4.

[0021] The specific embodiments described herein are merely illustrative examples illustrating the spirit of this utility model. Those skilled in the art to which this utility model pertains may make various modifications or additions to the described specific embodiments or use similar methods to substitute them, without departing from the spirit of this utility model or exceeding the scope defined by the appended claims.

[0022] Although this document frequently uses terms such as inlet 1, insulation cover 2, outlet 3, handle 4, sealing cover 5, mixing channel 6, support tray 7, heating block 8, partition cavity 9, air injection pipe 10, spoke plate 11, sealing strip 12, injection pipe 13, and arc-shaped passage 14, the possibility of using other terms is not excluded. The use of these terms is merely for the convenience of describing and explaining the essence of this utility model; interpreting them as any additional limitation would contradict the spirit of this utility model.
