Description

Technical Field

[0001] This utility model belongs to the technical field of grain and oil processing equipment, and relates to a self-cleaning air mesh structure for rice processing. Background Technology

[0002] Rice processing equipment has multiple air mesh structures for airflow entry or exit. These structures are used in rice sorting, slag removal, and polishing equipment. Regardless of whether the air mesh structure is used as an inlet or outlet air mesh, problems such as dust accumulation and rice residue remain on the mesh surface can occur, leading to a reduction in the mesh's ventilation rate and affecting the realization and effective implementation of the ventilation function.

[0003] Currently, the ventilation network needs to be dismantled and cleaned every certain period, especially the ventilation network with the air outlet function, which is more prone to accumulating dirt and clogging. This dismantling method not only affects the effective utilization rate of the equipment, but also increases the cost of using the equipment. Utility Model Content

[0004] The purpose of this invention is to address the aforementioned problems in existing technologies by providing a self-cleaning air mesh structure for rice processing. The technical problem this invention aims to solve is how to achieve self-cleaning of the air mesh.

[0005] The objective of this utility model can be achieved through the following technical solution: A self-cleaning air mesh structure for rice processing, characterized in that it includes an outer mesh ring, a core mesh plate, and a mesh sheet fixed between the outer mesh ring and the core mesh plate. A bearing is provided on the core mesh plate, the outer ring of the bearing is fixedly connected to the core mesh plate, the axis of the bearing is perpendicular to the mesh sheet, and an impeller located on the air outlet side of the mesh sheet is fixedly connected to the inner ring of the bearing. The impeller shaft is connected to the inner ring of the bearing. The impeller includes blades evenly distributed circumferentially on the impeller shaft, and the blades have brush portions that can contact the air outlet side of the air mesh.

[0006] Furthermore, the impeller shaft has a central insertion hole, into which a pin is inserted. The pin is threadedly connected to the inner ring of the bearing, and the outer wall of the impeller shaft is splinedly connected to the inner side of the inner ring of the bearing.

[0007] Airflow enters from the inlet side of the mesh and exits from the outlet side. During the exit process, the airflow causes the impeller to rotate due to the wind blowing through the blades. This rotation causes the brush section to contact the mesh on the outlet side, cleaning it in real time. The brush section consists of steel wire or plastic bristles distributed along the length of the impeller, essentially covering the entire mesh area. This keeps the mesh clean during ventilation, preventing dirt accumulation. Depending on the mesh's location, the impeller can be installed in either a normally installed or selectively installed state. For example, if the mesh is located on the outside of the equipment, the impeller can be removed under normal conditions and reinstalled after a period of operation. Attached Figure Description

[0012] 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.

[0013] like Figure 1 and Figure 2 As shown, the self-cleaning air mesh structure for rice processing includes an outer mesh ring 1, a mesh core plate 2, and a mesh sheet 3 fixed between the outer mesh ring 1 and the mesh core plate 2 for installation on the equipment frame. A bearing 4 is provided on the mesh core plate 2. The outer ring of the bearing 4 is fixedly connected to the mesh core plate 2. The axis of the bearing 4 is perpendicular to the mesh sheet 3. An impeller located on the air outlet side of the mesh sheet 3 is fixedly connected to the inner ring of the bearing 4. The impeller shaft is connected to the inner ring of the bearing 4. The impeller includes blades 5 evenly distributed circumferentially on the impeller shaft. The blades 5 have brush parts 6 that can contact the air outlet side of the air mesh.

[0014] like Figure 3 As shown, the impeller shaft has a central insertion hole, into which a pin 7 is inserted. The pin 7 is threadedly connected to the inner ring of the bearing 4, and the outer wall of the impeller shaft is splinedly connected to the inner side of the inner ring of the bearing 4. In this design, the impeller is a detachable structure, and disassembly and assembly, as well as impeller fixation, are achieved through the threaded connection between the pin 7 and the inner ring of the bearing 4, and the spline connection between the pin 7 and the inner ring of the bearing 4.

[0015] Airflow enters from the inlet side of mesh 3 and exits from the outlet side. During the exit process, the airflow causes the impeller to rotate due to the wind-driven blades 5. The rotation of the impeller causes the brush part 6 to contact the mesh 3 at the outlet side, cleaning the mesh 3 in real time. The brush part 6 is made of steel wire or plastic bristles, distributed along the length of the impeller, and can basically cover the entire area of ​​the mesh 3. In this way, the air screen is kept clean during ventilation, preventing dirt accumulation on the mesh 3. Depending on the location of the mesh 3, the impeller can be installed in a normal state or selectively. If the air screen is an externally exposed part of the equipment, the impeller can be removed under normal conditions and installed after running for a certain period of time.

[0016] 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.
