Description

Technical Field

[0001] This utility model relates to the field of size detection devices, specifically an alumina grain size control device. Background Technology

[0002] Alumina grains exhibit varying atomic densities and symmetries across their different crystal planes, resulting in significant differences in electronic structure, surface energy, and chemical activity. By modulating the limiting factors of alumina grain growth and controlling the type and proportion of crystal planes, deep control over key physicochemical properties of alumina, such as specific surface area, pore structure, acidity, and atomic and molecular chemical environment, can be achieved from the source. While alumina grain size detection devices are used to measure the length, width, and height of alumina grains, their efficiency, comprehensiveness, and accuracy are low in practical applications. Therefore, we propose an alumina grain size control device. Utility Model Content

[0003] The purpose of this invention is to provide an alumina grain size control device to solve the problems of low detection efficiency, insufficient detection, and poor detection accuracy in the prior art.

[0004] To achieve the above objectives, this utility model provides the following technical solution: an alumina grain size control device, comprising a fastening frame, side protective plates installed on both sides of the inner side of the fastening frame, an infrared emitter A installed on one side of the side protective plates, a rectangular mounting plate installed at the upper position between the side protective plates, a limiting bridge installed on the rectangular mounting plate, a feeding belt installed on the inner side of the fastening frame, an alumina grain storage cavity provided on the feeding belt, alumina grains placed in the alumina grain storage cavity, a control box installed on one side of the outer side of the fastening frame, a fastening plate installed on the top of the fastening frame, the two ends of the fastening plate being connected to the fastening frame through connecting blocks, and an infrared emitter B installed at the bottom of the fastening plate.

[0005] Preferably, the infrared transmitter A, infrared transmitter B, and the output terminal of the limit bridge are all electrically connected to the input terminal of the control box.

[0006] Preferably, the limiting cable tray is provided with a detection net composed of infrared rays at the aperture position.

[0007] Preferably, there are three limiting cable trays, and the three limiting cable trays are evenly installed on the rectangular mounting plate.

[0008] Compared with the prior art, the beneficial effects of this utility model are as follows: An inner feeding belt is installed on the inner side of the utility model, and an alumina grain storage cavity is provided on the feeding belt. Three alumina grains can be placed simultaneously in the alumina grain storage cavity. By detecting the three alumina grains, the detection efficiency is greatly increased. Furthermore, three limiting bridges are installed directly above the alumina grain storage cavity via a rectangular mounting plate. These three limiting bridges can not only detect the area of ​​the cross-section of the alumina grains but also limit the conveying of the alumina grains. Infrared emitters A and B are respectively installed on the top and sides of the device. Through the cooperation of these three detection devices, the length, width, and height of the alumina grains can be detected simultaneously from multiple sides, greatly increasing the detection accuracy.

A rectangular mounting plate 7 is installed near the upper position between the side protective plates 2. The rectangular mounting plate 7 is used to fix a limiting bridge 5. The limiting bridge 5 is installed on the rectangular mounting plate 7. The limiting bridge 5 can limit the conveying position of the alumina grains 6 and detect the cross-sectional area of ​​the alumina grains 6. A feeding belt 4 is installed inside the fastening frame 8. The feeding belt 4 is used to convey the alumina grains 6. An alumina grain storage cavity 9 is provided on the feeding belt 4. Alumina grains 6 are placed in the alumina grain storage cavity 9. A control box 12 is installed on one side of the outer side of the fastening frame 8. The control box 12 is used to analyze the dimensional detection data. A fastening plate 10 is installed on the top of the fastening frame 8. The fastening plate 10 is used to fix the infrared transmitter B11. The two ends of the fastening plate 10 are connected to the fastening frame 8 through the connecting block 1. The infrared transmitter B11 is installed at the bottom of the fastening plate 10. The infrared transmitter B11 is used to detect the dimensions of the upper surface of the alumina grains 6.

The alumina crystals 6 are conveyed by the feeding belt 4. When they pass through the aperture of the limiting bridge 5, the infrared mesh on the aperture will detect the size of their cross-sectional area. At the same time, the infrared emitters A3 and B11 will detect the size of their side and top surfaces, and transmit the detection information to the control box 12. After the control box analyzes the information, accurate data is obtained.
