Description

Technical Field

[0001] The utility model relates to the technical field of asphalt fume degradation evaluation, and more specifically, to an evaluation device for the degradation effect of asphalt fume for experimental use. Background Technique

[0002] Under high temperature (120 - 180 °C) conditions, various harmful gases will be released during the mixing and paving of asphalt mixtures. Researchers at home and abroad have conducted a large number of studies and animal experiments on the harms caused by harmful gases from aspects such as medicine and genetic toxicology. The research shows that harmful gases will produce genetic toxicity effects, and there are risks such as inducing gene mutations and cancers; they will damage the pulmonary ventilation function and organs such as the liver and kidneys, cause industrial fluorosis, and present phenomena such as decreased blood calcium and disordered human metabolism; in addition, harmful gases will also cause chronic respiratory diseases such as mucosal irritation, pharyngitis, and rhinitis, and then affect the cardiovascular system of people. Although warm mixing and cold mixing technologies have been proposed successively in recent years, due to their application limitations, hot mix asphalt mixtures still dominate.

[0003] As a new type of additive, the odor remover can effectively degrade the harmful gases produced by hot mix asphalt. The concentration of harmful gases is detected by using an ultraviolet-visible spectrophotometer. The ultraviolet-visible spectrophotometer is an analytical instrument widely used at present. It can decompose light with complex components into spectral curves, and each substance has its own unique absorption spectral curve. Then, the concentration of the measured substance can be calculated according to the characteristic waveforms in the curve. By calculating the concentration of the measured substance, the degradation effect of asphalt fume can be evaluated;

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0028] In order to enable those skilled in the art to better understand the solution of the present utility model, the technical solutions in the embodiments of the present utility model will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present utility model.

[0029] As recorded in the background art, in the prior art, most of the control panels of ultraviolet-visible spectrophotometers are exposed and protruded. During the process of carrying and moving, the protruding and exposed control panel is easily bumped and damaged.

[0030] To solve this technical problem, the present utility model provides an evaluation device for the degradation effect of experimental asphalt fume, which is applied to the evaluation of the degradation effect of asphalt fume.

[0031] Specifically, please refer to Figures 1 - 3 , the evaluation device for the degradation effect of experimental asphalt fume specifically includes:

[0032] The ultraviolet-visible spectrophotometer main body 1 and the operation panel main body 3. An installation groove 2 is opened at the top of the ultraviolet-visible spectrophotometer main body 1. The operation panel main body 3 is installed at the bottom in the inner cavity of the installation groove 2, and a protection mechanism 4 for protecting the operation panel main body 3 is installed in the installation groove 2.

[0033] For the evaluation device for the degradation effect of experimental asphalt fume provided by the present utility model, through the provided installation groove 2 and the protection mechanism 4, the setting of the installation groove 2 enables the operation panel main body 3 to be designed in a sunken manner. This setting makes the operation panel main body 3 not easily bumped due to protrusion during the process of carrying and moving, and the operation panel main body 3 is well protected under the protection of the protection mechanism 4, thereby further reducing the situation of being bumped and damaged.

[0034] In order to enable those skilled in the art to better understand the solution of the present utility model, the technical solutions in the embodiments of the present utility model will be clearly and completely described below in conjunction with the drawings.

[0035] It should be noted that, without conflict, the embodiments in the present utility model and the features and technical solutions in the embodiments can be combined with each other.

[0036] It should be noted that similar reference numerals and letters indicate similar items in the following drawings. Therefore, once an item is defined in one drawing, it does not need to be further defined and explained in subsequent drawings.

[0037] Embodiment 1, please refer to Figures 1 - 3, An evaluation device for the degradation effect of asphalt fume for experimental use, including a main body 1 of an ultraviolet-visible spectrophotometer and a main body 3 of an operation panel. An installation groove 2 is opened at the top of the main body 1 of the ultraviolet-visible spectrophotometer. The main body 3 of the operation panel is installed at the bottom in the inner cavity of the installation groove 2, and a protection mechanism 4 for protecting the main body 3 of the operation panel is installed in the installation groove 2. Through the provided installation groove 2 and the protection mechanism 4, the installation groove 2 enables the main body 3 of the operation panel to be designed in a sunken manner. This setting makes it difficult for the main body 3 of the operation panel to be bumped due to protrusion during the process of carrying and moving, and the main body 3 of the operation panel is well protected under the protection of the protection mechanism 4, thereby further reducing the situation of being damaged by bumps.

[0038] Further, as Figures 1 - 3 shown, the protection mechanism 4 includes a connection seat 401 fixedly installed in the installation groove 2. A connection groove 402 is opened at the top of the connection seat 401. A first connection shaft 403 is provided between the connection groove 402 and the connection seat 401, and a connection plate 404 located in the connection groove 402 is sleeved on the outer surface of the first connection shaft 403. A second protection plate 409 is fixedly connected to one side of the connection plate 404. The second protection plate 409 is located above the main body 3 of the operation panel. The second protection plate 409 can rotate around the first connection shaft 403, so that when the second protection plate 409 rotates above the main body 3 of the operation panel, it can protect the main body 3 of the operation panel, and when in use, the second protection plate 409 can be rotated away from directly above the main body 3 of the operation panel.

[0039] Further, as Figures 1 - 4 shown, a slot 5 is opened on the inner wall of the installation groove 2 on the side away from the connection seat 401. A receiving groove 407 is opened in the second protection plate 409. A first protection plate 405 is inserted and connected in the receiving groove 407. One side of the first protection plate 405 extends out of the receiving groove 407 and is inserted into the slot 5. The insertion of the first protection plate 405 into the slot 5 can limit the second protection plate 409.

[0040] Further, as Figure 4 shown, a push plate 406 is fixedly connected to the top of the first protection plate 405. The push plate 406 is located outside the receiving groove 407. The setting of the push plate 406 facilitates the pushing of the first protection plate 405.

[0041] Example 2 further optimizes the evaluation device for the degradation effect of asphalt fume for experimental use provided in Example 1. Specifically, as Figure 4 shown, two connecting rods 411 are fixedly installed in the receiving groove 407. Sliding plates 412 are sleeved on the outer surfaces of the two connecting rods 411. One side of each of the two sliding plates 412 close to each other is fixedly connected to the first protection plate 405. The mutual cooperation of the connecting rods 411 and the sliding plates 412 can limit the first protection plate 405.

[0042] Further, as Figure 4 shown, a spring 413 is sleeved on the outer surface of the connecting rod 411. The two ends of the spring 413 are fixedly connected to the sliding plate 412 and the connecting rod 411 respectively. The acting force of the spring 413 can apply an acting force to move the first protection plate 405 outward from the accommodating groove 407 through the sliding plate 412 and the spring 413.

[0043] Further, as Figure 3 and Figure 4 shown, a plurality of first through holes 408 are formed in the second protection plate 409, and a plurality of second through holes 410 are formed in the first protection plate 405. The number and positions of the first through holes 408 correspond to the number and positions of the second through holes 410. When the first protection plate 405 is pushed into the accommodating groove 407, the first through holes 408 can be aligned with the second through holes 410. At this time, after inserting the colorimetric cuvette between the first through holes 408 and the second through holes 410, the colorimetric cuvette can be clamped, so as to provide an additional support structure for the colorimetric cuvette to facilitate detection.

[0044] Example 3 further optimizes the test device for evaluating the degradation effect of asphalt fume provided in Example 1 or 2. Specifically, as Figure 1 and Figure 2 shown, a side groove 6 is formed on one side of the ultraviolet-visible spectrophotometer main body 1. A support plate 8 is arranged in the side groove 6. A second connecting shaft 9 is arranged between the support plate 8 and the inner wall of the side groove 6. When the support plate 8 is located inside the side groove 6, it is limited by the frictional force between the inner walls of the support plate 8. When the support plate 8 rotates horizontally, when a colorimetric cuvette is placed in the first through holes 408 and the second through holes 410, the support plate 8 can support the colorimetric cuvette.

[0045] Further, as Figure 2 shown, the two ends of the second connecting shaft 9 are fixedly connected to the inner walls on both sides of the side groove 6 respectively. The support plate 8 is sleeved on the outer surface of the second connecting shaft 9, and the support plate 8 can be installed in the side groove 6 through the second connecting shaft 9.

[0046] Further, as Figure 2 shown, a buckle groove 10 is formed at the top of the support plate 8. When the support plate 8 is erected and hidden inside the side groove 6, the support plate 8 can be rotated horizontally around the second connecting shaft 9 by pulling the support plate 8 from the buckle groove 10 with fingers.

[0047] The using process of the test device for evaluating the degradation effect of asphalt fume provided by the present utility model is as follows:

[0048] Use a finger to pull the support plate 8 from the buckle groove 10 so that the support plate 8 rotates horizontally around the second connecting shaft 9, push the push plate 406 in the direction of the second protective plate 409 so that the push plate 406 drives the first protective plate 405 to separate from the slot 5, rotate the second protective plate 409 so that the second protective plate 409 rotates from directly above the operation panel main body 3 to above the support plate 8, push the first protective plate 405 into the accommodation groove 407 so that the first through hole 408 coincides with the second protective plate 409, that is, as Figure 5 shown, then insert the required cuvette between the first through hole 408 and the second through hole 410. After releasing the first protective plate 405, the acting force of the spring 413 drives the first protective plate 405 to move outward so that the cuvette is clamped between the first through hole 408 and the second through hole 410, and corresponding detection can be carried out through the ultraviolet-visible spectrophotometer main body 1;

[0049] After use, push the first protective plate 405 towards the second protective plate 409 and then rotate the second protective plate 409 to directly above the operation panel main body 3 so that the second protective plate 409 is inserted into the slot 5, and then rotate the support plate 8 to be erected and hidden in the side slot 6, that is, as Figure 1 shown.
