Technical Field

[0001] The invention relates to a device for measuring anti-breakage performance, and in particular to a device for measuring anti-breakage performance, one of the physical qualities of biomass molded fuel. Background Art

[0002] Biomass briquette fuel is easily subject to collision and friction during transportation and storage, which causes the fuel to break, affecting its combustion efficiency and use effect. Breakage resistance is an important indicator to measure the ability of biomass briquette fuel to resist breakage during transportation, storage and use. It is closely related to the molding quality. Measuring the breakage resistance of biomass briquette fuel is of great significance for evaluating its quality and durability. Therefore, a device for measuring the breakage resistance of biomass briquette fuel is needed. Summary of the invention

[0003] The purpose of the present invention is to provide a device for measuring the anti-breakage property of biomass molded fuel which has a simple structure, is easy to operate and has high measuring accuracy.

[0004] The technical solution adopted by the present invention is: a biomass molding fuel anti-breakage test device, characterized in that: the molded fuel is placed in a test box, a partition is arranged in the test box, when the test device is started, the left and right test boxes will rotate at the same time, and the biomass molding fuel will collide with the partition inside, when the test device stops working, the top cover of the test box is opened, the biomass molding fuel residue is poured out, and the anti-breakage test of the biomass molding fuel is completed. The present invention is mainly composed of a test box (right), a test box (left), a top cover, a partition, a rotating shaft, a flange, a base, a display screen, a start button, and an acceleration / deceleration button. The test box is located on both sides of the base, and the measured anti-breakage can be verified while maintaining the balance of the overall structure. The test box is a rectangular structure, made of hard material, 300mm long, 125mm wide, and 300mm high. A partition is installed in the box, and the partition is installed along the diagonal of a 300mm×300mm plane. Two test boxes with the same structure are fixed to the rotating shaft through flanges. The axis of the rotating shaft is consistent with the central axis of the 300mm×300mm side of the test box, so that the test box can rotate synchronously with the rotating shaft. A display screen, a start button, and an acceleration / deceleration button are set on the base to intuitively display information such as rotation speed and running time. The rotating shaft connects the left and right test boxes. BRIEF DESCRIPTION OF THE DRAWINGS

[0012] Specific implementation measures

[0013] refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 As shown, a device for measuring the resistance of biomass molded fuel to breaking, the device includes multiple key steps and components during its specific implementation to meet the requirements of measuring the resistance of biomass molded fuel to breaking.

[0014] A biomass briquette fuel anti-breakage test device is composed of two left and right test boxes (1, 7), which are fixedly connected to a rotating shaft (8) through a flange (11), and the axis of the rotating shaft (8) and the central axis of the test boxes (1, 7) are consistent, so that the two test boxes (1, 7) can rotate synchronously with the rotating shaft (8) and two sets of anti-breakage data are measured at the same time. The two test boxes (1, 7) are made of steel material to ensure that the biomass briquette fuel anti-breakage measurement meets the standard.

[0015] The base (9) of the device is equipped with a tachometer, which can display the rotation speed on the display screen (2) and control the rotation speed through an acceleration button (3) or a deceleration button (4). When in use, the top cover (6) of the test box (1, 7) is opened, and the biomass molding fuel sample is placed in the test box (1, 7), and rotated at a set speed. The rotation causes the samples to collide with each other and with the inner wall and partition of the test box. After the rotation is completed, the worn fine particles in the test box (1, 7) are separated, and the crushing resistance is calculated based on the remaining sample mass. The present invention has a simple structure and is easy to operate. It can effectively measure the anti-drop and crushing performance of biomass molding fuel and is suitable for research and production in related fields.
