Embodiment Construction

[0037] Attached to the following Figure 1-7 This application will be described in further detail.

[0038] The embodiment of the present application discloses an asphalt softening point measuring instrument, such as figure 1 As shown, it includes a shield 1, a console 12, a column 121 and a top plate 122. The shield 1 is fixedly installed on the upper surface of the shield 1, and the top side of the shield 1 is open. There are two uprights 121 , both of which are fixedly connected to the upper surface of the console 12 , and the top plate 122 is fixedly connected to the ends of the two uprights 121 away from the workbench at the same time. Two hydraulic cylinders 123 are fixedly installed on the bottom side of the top plate 122 , and a cover plate 124 is fixedly connected to the telescopic rods of the two hydraulic cylinders 123 , and the cover plate 124 is matched with the opening of the shield 1 . A connecting rod 13 is fixedly connected to the bottom side of the cover pl...

Abstract

The present application relates to an asphalt softening point measuring instrument, comprising a protective cover, a suction assembly is arranged on one side of the protective cover, and the suction component includes a suction pipe, a suction pump and a purification box, and the purification box is fixedly installed on one side of the protective cover On the ground, the suction pump is fixedly installed on the purification box, one end of the suction pipe is connected with the shield, the air inlet of the suction pump is connected with the suction pipe, and the exhaust pipe of the suction pump is connected with the air inlet of the purification box. The air inlets are connected; the purification box is provided with purification components for purifying the gas. When the asphalt in the shield starts to heat, start the suction pump first, so that the suction pump can extract the gas in the shield through the suction pipe, and the gas passing through the suction pump is then introduced into the exhaust pipe of the suction pump. In the purification box, the gas in the purification box is purified by the purification components and then discharged, so as to achieve the purpose of easy absorption of the toxic gas generated by the heating of the asphalt.

Description

technical field [0001] The present application relates to the technical field of asphalt testing, in particular to an asphalt softening point measuring instrument. Background technique [0002] Asphalt is a dark-brown complex mixture composed of hydrocarbon machine non-metallic derivatives of different molecular weights, and is a kind of high-viscosity organic liquid. The main performance indicators of asphalt are asphalt ductility, penetration and softening point. The asphalt softening point test is suitable for determining the softening point of road petroleum asphalt and coal tar pitch, and also suitable for determining the softening point of liquid petroleum asphalt remaining after distillation or softening asphalt evaporation. . [0003] For related technologies, refer to the Chinese utility model patent with the authorized announcement number CN211627425U, which discloses an asphalt softening point measuring instrument, including a console, the upper end of the consol...
