Description

Technical Field

[0001] The utility model belongs to the technical field of asphalt transportation, and in particular relates to a rapid heating and stirring system for a train tank. Background Art

[0002] Asphalt has the characteristic of condensing at low temperatures, so it needs to be filled at high temperatures at the place of origin. After long-distance transportation, it cools down and solidifies into a semi-solid state, and needs to be heated and unloaded at the destination.

[0003] At present, after the train tank arrives at the destination, high-temperature steam is introduced through the heating pipe at the bottom for heating. It usually takes 8-10 hours to heat up, and the heating rate is slow, resulting in a waste of energy and time. Utility Model Content

[0021] The technical solution of the present invention is described in detail below with reference to the accompanying drawings. The following embodiments are merely exemplary and can only be used to explain and illustrate the technical solution of the present invention, and cannot be interpreted as limiting the technical solution of the present invention.

[0022] like Figure 1 and Figure 2 As described above, the present application provides a rapid heating and mixing system for a train tank. The technical solution of the present application does not involve any improvement to the structure of the train tank. The train tank of the present application is a conventional asphalt tank used for transporting asphalt by train. A manhole 11 is provided above the asphalt tank, which is a conventional technology and a necessary structure in this field. A heating coil is provided near the bottom of the asphalt tank. The two ends of the heating coil extend out of the train tank and are fixed to the train tank by welding or other means. In the technical solution of the present application, the heating coil 13 uses a steam heating tube. In other embodiments of the present application, the heating coil can also be an electric heating tube, which is connected to an external power source to provide electricity for heating the asphalt.

[0023] In other embodiments of the present application, the heating coil can also be used as a movable structure. After the train tank stops at a fixed position on the trestle 1, the heating coil is placed into the train tank through the upper manhole or feed hole of the train tank.

[0024] The trestle 1 of the present application is a conventional trestle structure. A lifting motor 2 is provided on the trestle 1. The lifting motor 2 is electrically connected to an external power supply. When the train tank 12 is not heated, or when there is no train tank 12 on the trestle 1, the lifting motor 2 drives the slide rail 5 to move upward to the highest position to avoid interference with other components or functions.

[0025] In other embodiments of the present application, vertical slide rails 7 perpendicular to the ground and fixed to the trestle or other parts such as the foundation can also be provided at both ends of the slide rail 5. The slide rail 5 moves up and down within the two vertical slide rails 7 to prevent the slide rail 5 from moving left and right. The above-mentioned slide rails of the present application can all be existing technologies, and those skilled in the art can also process and manufacture them according to the above-mentioned technical solutions, which does not affect the implementation of the technical solutions of the present application.

[0026] In the present application, slide rail grooves are provided on the front and rear sides of the slide rail 5, and the telescopic device 3 is placed in the corresponding slide rail grooves through two pulleys. A movable motor 6 is provided at one end of the slide rail, and the telescopic device 3 is driven to move back and forth by the movable motor 6. Its principle and structure are similar to the structure of the existing gantry crane, and those skilled in the art can obtain it by referring to the gantry crane.

[0027] A telescopic cylinder 4 is provided below the telescopic device 3 , and a stirring motor 9 is provided at the lower end of a piston rod 8 of the telescopic cylinder 4 .

[0028] In other embodiments of the present application, the telescopic device may also include a telescopic motor. In this case, the specific structure of the telescopic device includes a telescopic motor, a fixed tube, and a rotating shaft core arranged in the fixed tube. The upper end of the fixed tube is connected to the housing of the telescopic motor or the telescopic device, the upper end of the rotating shaft core is fixedly connected to the output shaft of the telescopic motor, and the lower end of the rotating shaft core is connected to the agitator.

[0029] The blender 10 of the present application includes a blender housing 101, which is formed by connecting two half shells. A blender blade 102 is disposed within the blender housing 101. The blender housing of the present application can be referred to as the blade housing of a conventional fan. When a telescopic motor is used, the blender can also rotate horizontally. In this case, the rotation is the rotation of the entire blender, not necessarily the rotation of the blender blades.

[0030] The stirring motor 9 is mounted at the lower end of the piston rod 8 of the telescopic cylinder. The stirring motor's output shaft is perpendicular to the piston rod of the telescopic cylinder. The plane formed by the rotating stirring blades is parallel to the piston rod. The bottom end of the stirring housing is lower than the lowest end of the heating coil.

[0031] The working principle is:

[0032] Connect each motor to the corresponding power supply. When the train tank that needs to be heated docks on the trestle, connect the external steam to the air inlet and outlet of the heating coil to heat the asphalt in the train tank. At the same time, the lifting motor drives the slide rail to move downward to the position above the train tank. Then start the moving motor to drive the telescopic device with the stirrer to move to the top of the manhole of the train tank. Then start the telescopic cylinder or telescopic motor to pass the stirrer into the train tank through the manhole. Then start the stirring motor. The stirring blades of the stirrer rotate to stir the melted asphalt to achieve the purpose of forced convection heat exchange.

[0033] In addition, it should be understood that although this specification is described in terms of implementation methods, not every implementation method contains only one independent technical solution. This narrative method of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other implementation methods that can be understood by those skilled in the art.
