Abstract

This utility model discloses an integrated airflow dispersion device for powdered materials, including a base plate and a fixed frame. The fixed frame is fixedly installed on one side of the upper end of the base plate, and a dispersion conveying structure is installed on the other side of the upper end of the base plate. A powder storage structure is installed on the upper end of the fixed frame. The dispersion conveying structure includes: a limiting rod, a rotating plate, a high-pressure blower, an installation pipe, a rotating flange, a dispersion box, two transverse dispersion plates, two longitudinal dispersion plates, and a Venturi tube.

Description

Technical Field

[0001] This utility model relates to the field of powder conveying technology, specifically to an integrated device for airflow dispersion of powdery materials. Background Technology

[0002] During the processing of powdered materials, the materials often clump together due to moisture absorption, static electricity, or stacking pressure, and need to be efficiently dispersed to meet the requirements of subsequent processes.

[0003] Traditional dispersion processes typically employ separate equipment. Materials are first temporarily stored in a storage silo, then transferred to an independent dispersion unit via a screw conveyor, and finally dispersed using high-pressure airflow. This process requires multiple material transfers, increasing the risk of dust leakage, polluting the environment, and causing raw material loss. Furthermore, the dispersion unit is fixed in its installation, making it impossible to adjust the spray direction to adapt to different working conditions. The single dispersion structure easily leads to insufficient mixing between the dispersion airflow and the material, requiring higher air pressure to achieve the desired crushing effect, resulting in a significant increase in energy consumption. In view of these issues, existing technologies may already provide solutions to the above problems. However, this application aims to provide an alternative or replacement technical solution.

[0005] The dispersion conveying structure includes: a limiting rod, a rotating plate, a high-pressure blower, an installation pipe, a rotating flange, a dispersion box, two transverse dispersion plates, two longitudinal dispersion plates, and a Venturi tube;

[0006] The limiting rod is fixedly installed on the other side of the upper end of the base plate. The rotating plate is movably mounted on the upper end of the limiting rod via a bearing and is located on the upper end of the base plate. The high-pressure blower is fixedly installed on one side of the upper end of the rotating plate. One end of the mounting pipe is connected to the air outlet of the high-pressure blower. One end of the rotating flange is connected to the upper end of the mounting pipe. The bottom end of the mounting pipe is fixedly connected to the top end of the limiting rod. One end of the dispersion box is connected to the other end of the mounting pipe. Two transverse dispersion plates and two longitudinal dispersion plates are staggered in the dispersion box.

[0012] Beneficial effects

[0013] This utility model provides an integrated airflow dispersion device for powdered materials, which has the following advantages: The device directly connects a high-pressure blower, a venturi tube, and a dispersion box with a built-in staggered dispersion plate to form a high-speed turbulent flow field, which forcibly breaks up agglomerated materials.

The screw conveyor is dynamically connected to the mounting pipe through the rotating flange, realizing continuous and closed conveying of powder from the storage box to the dispersion airflow, preventing dust from escaping. The storage, conveying, and dispersion modules are integrated on the bottom plate and the upper part of the fixed frame, reducing the space occupied. Attached Figure Description

Two transverse dispersion plates 9 and two longitudinal dispersion plates 10 are staggered in the dispersion box 8. One end of the venturi tube 11 is connected to the other end of the dispersion box 8.

[0022] When processing the powder, the worker first injects the powder into the powder storage structure at the upper end of the fixed frame 2. Then, the powder is conveyed to the installation pipe 6 through the powder conveying structure. Subsequently, the high-pressure blower 5 operates to convey high-pressure gas, which mixes the powder in the installation pipe 6 with the high-pressure gas and conveys it to the dispersion box 8. The powder is dispersed by two staggered horizontal dispersion plates 9 and two vertical dispersion plates 10.

[0025] When storing powder, the powder is injected into the storage box 13 at the upper end of the two support frames 12. Then, the screw conveyor 14 works to transport the powder in the storage box 13 to the connecting pipe 15. The connecting pipe 15 cooperates with the rotating flange 7 to transport the powder to the installation pipe 6. Finally, the powder is dispersed by the dispersing conveying structure and transported to the designated location.
