Description

Technical Field

[0001] The utility model belongs to the technical field of asphalt sampling, and in particular relates to an asphalt production sampling device. Background Art

[0002] Asphalt is a dark brown complex mixture composed of hydrocarbons of different molecular weights and their non-metallic derivatives. It is a kind of high-viscosity organic liquid, mostly in the form of liquid or semi-solid petroleum. It has a black surface and is soluble in carbon disulfide and carbon tetrachloride. Asphalt is an organic gelling material that is waterproof, moisture-proof and corrosion-resistant. Asphalt can be mainly divided into three types: coal tar asphalt, petroleum asphalt and natural asphalt. Among them, coal tar asphalt is a by-product of coking; petroleum asphalt is the residue after crude oil distillation; natural asphalt is stored underground, some of which form mineral layers or accumulate on the surface of the earth's crust; asphalt is mainly used in industries such as coatings, plastics, rubber, and road paving.

[0003] Currently, during asphalt production, a sampling device is usually required to sample asphalt. However, the existing asphalt production sampling device has the following problems when used: the sampling port of the existing asphalt sampling device is not sealed, which can easily cause asphalt of different depths to mix during sampling, resulting in poor sampling effect and failure to achieve the effect of independent sampling.

[0008] It is further defined that the guide mechanism includes a guide mounting frame, a guide rod is mounted in the guide mounting frame, the guide rod is slidably connected to a slider, the slider is connected to a locking rod, and the other side of the locking rod is locked and mounted on the mounting frame.

[0020] In order to enable those skilled in the art to better understand the present invention, the technical solution of the present invention is further described below in conjunction with the accompanying drawings and embodiments.

[0021] Embodiment 1, as Figure 1 and Figure 2 As shown, an asphalt production sampling device, the bottom of the sampling tube 1 is set in a conical structure, the bottom of the sampling tube 1 is provided with an opening 2, a blocking seat 3 is installed in the opening 2, a cone head 4 is installed at the bottom of the blocking seat 3, a connecting rod 5 is installed on the top of the blocking seat 3, the connecting rod 5 is arranged in the sampling tube 1, the top of the connecting rod 5 passes through the sampling tube 1 and extends to the upper side thereof, a limiting slide bar 6 is installed on the top of the limiting slide bar 6, a limiting plate 7 is installed on the top of the sampling tube 1, and a mounting frame is fixedly installed on the top of the sampling tube 1 8. A hydraulic cylinder 9 is installed on the top of the mounting frame 8, and the power output end of the hydraulic cylinder 9 is connected to the limit plate 7. The limit slide bar 6 and the limit plate 7 are both arranged in the mounting frame 8. A depth adjustment mechanism 10 is installed on the left side of the mounting frame 8, and a guide mechanism 11 is installed on the right side of the mounting frame 8. The interior of the sampling tube 1 is provided with a heating layer 12 and a heat preservation layer 13 from the inside to the outside. Exhaust holes 14 arranged in an L-shaped structure are also provided on both sides of the top of the sampling tube 1, and an exhaust valve 15 is installed in the exhaust hole 14.

[0022] In this embodiment, when sampling is required during the asphalt production process, the depth adjustment mechanism 10 drives the mounting frame 8, and the mounting frame 8 drives the sampling tube 1 to move, while the other side of the mounting frame 8 performs a stable guiding movement under the effect of the guide mechanism 11, so that the mounting frame 8 pushes the sampling tube 1 to move into the asphalt. After reaching the appropriate sampling depth, the hydraulic cylinder 9 is started to make the hydraulic cylinder 9 push the limit plate 7, the limit plate 7 pushes the limit slide 6, the limit slide 6 pushes the connecting rod 5, the connecting rod 5 pushes the blocking seat 3, and the blocking seat 3 pushes the cone head 4 to move downward until the hydraulic cylinder 9 pushes the limit plate 7 to contact the top of the sampling tube 1, which means that the blocking seat 3 is removed from the opening 2. After the blocking seat 3 leaves the opening 2, the bottom of the sampling tube 1 is opened, and the depth is reached. Under the push of the depth adjustment mechanism 10, the asphalt at a deep depth is sampled, so that the asphalt enters the sampling tube 1 through the opening 2. After the asphalt enters the sampling tube 1, the air inside it will be squeezed, so that the air in the sampling tube 1 is discharged from the exhaust hole 14 through the exhaust valve 15, so as to facilitate the sampling work of the sampling tube 1. After the sampling work is completed, the hydraulic cylinder 9 is controlled to reset. When the hydraulic cylinder 9 drives the limit plate 7 to reset, the top of the limit plate 7 contacts the mounting frame 8, which means that the blocking seat 3 is already located in the opening 2, which has a blocking effect on the opening 2 to prevent asphalt from other depths from entering. The asphalt in the sampling tube 1 can effectively prevent the asphalt from solidifying and being unable to be taken due to the effect of the heating layer 12 and the insulation layer 13, thereby improving the use effect.
