Description

Technical Field

[0001] The utility model belongs to the technical field of weak light catalysis detection, and more specifically, particularly relates to a weak light catalysis detection experimental box. Background Art

Through experiments, researchers can gain a deeper understanding of the mechanism and kinetics of photocatalytic reactions, which will help develop more efficient and stable photocatalysts and improve the efficiency and reliability of photocatalytic technology.

[0004] The above-mentioned "a formaldehyde detection and photocatalytic formaldehyde removal device" still has some disadvantages. For example, in the existing weak photocatalytic detection process, it is often necessary to manually place the odor-free coating plate into the weak photocatalytic box, and manual placement may cause collisions with the equipment in the weak photocatalytic box, such as lamps. At the same time, the coating plate is simply placed inside the experimental box, and the light on the surface of the coating plate after placement will change due to the distance from the light source, which reduces the uniformity of the light on the coating surface and reduces the accuracy of the reaction measurement data;

[0005] For this reason, a weak photocatalytic detection experimental box is proposed here to solve the above-mentioned problems. Utility Model Content

[0006] In view of the deficiencies in the prior art, the utility model provides a weak photocatalytic detection experimental box to solve the problem raised in the above background technology that manual placement may cause collision impact on equipment such as lamps in the weak photocatalytic box, and that the light received by the surface of the coated plate after placement will change due to the distance from the light source.

At the same time, during the movement of the clamping plate, the sliding of the clamping pad along the surface of the bottom slide rail can improve the stability of the movement of the clamping plate. By clamping the coating plate in a portable manner, the stability of the coating plate during the test can be improved;

[0015] 2) During the operation of the weak light catalytic detection test box, the sealing plate can be limited by the inner limit frame.

[0038] The specific usage and function of this embodiment: During the daily work of the weak light catalytic detection experimental box, the operator first places the coating plate along the side connecting frame 701 on one side of the side limiting plate 907. At this time, after the electric push rod 902 is started, the connecting plate 903 is driven by the electric push rod 902 to move horizontally. The movement of the connecting plate 903 will push the two clamping plates 904 to move along the surface of the side limiting plate 907. The clamping plate 904 can be used to clamp the coating plate on one side of the side limiting plate 907, and the coating plate can be limited. At the same time, the clamping pad 905 on one side of the clamping plate 904 is used to fit with one side of the coating plate, which can improve the stability of the coating plate after being clamped in the side limiting plate 907. At the same time, during the movement of the clamping plate 904, the sliding of the clamping pad 905 along the surface of the bottom slide rail 908 can improve the stability of the movement of the clamping plate 904. By clamping the coating plate in a portable manner, the stability of the coating plate during the test can be improved.

[0039] At the same time, after the coated plate is placed on the surface of one of the side limit plates 907 for clamping, the motor body 801 is started, and the transmission rod 802 is driven to rotate by the motor body 801. The rotating transmission rod 802 drives the top ring frame 803 to rotate along the inner side of the experimental box 1, and the multiple side limit plates 907 on the surface of the top ring frame 803 can be rotated to one side of the side connecting frame 701 respectively, and the operator clamps the coated plate on the surface of the multiple side limit plates 907;

The inner limiting frame 703 can be used to limit the sealing plate 705. At the same time, when the sealing plate 705 contacts the inner limiting frame 703, the clamping cushion 706 on one side of the sealing plate 705 will fit with the connecting groove 704, which can improve the tightness of the sealing plate 705 and the inner limiting frame 703 after fitting.

At the same time, after the motor body 801 in the bottom fixing box 805 is started, the top ring frame 803 is driven by the motor body 801 to rotate stably at a uniform speed. The top ring frame 803 that rotates at a constant speed and stably will drive multiple coated plates to rotate along the bulb body 6, which can ensure that the illumination of various parts of the coating surface is more uniform. By ensuring the uniformity of illumination on the coating surface, the error caused by uneven illumination can be reduced, the accuracy and reliability of the experiment can be improved, and data can be obtained through the sensor 5 and the data display 4;
