Description

Technical Field

[0001] The utility model belongs to the technical field of tank car transportation, and particularly relates to a heat transfer oil heating device in a train tank. Background Art

[0002] Heavy oils such as crude oil and asphalt have the characteristic of condensing at low temperatures. They need to be filled at high temperatures at the place of origin. After long-distance transportation, they cool down and solidify into a semi-solid state, and need to be heated and unloaded at the destination.

[0003] Currently, after the train tank arrives at its destination, it is heated by passing high-temperature steam through the heating pipe at the bottom. This usually takes 8-10 hours, resulting in a slow heating rate and a waste of energy and time. Therefore, how to improve heating efficiency has been a topic of research for those skilled in the art.

[0019] 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.

[0020] like Figure 1 and Figure 2 As shown, the present application provides a thermal oil heating device in a train tank, including a mobile heater movably arranged in the train tank, the mobile heater including a connecting plate 2, a telescopic mechanism arranged on the connecting plate 2, and a heating oil pipe 4 arranged below the telescopic mechanism. The heating oil pipe 4 is a frame structure formed by vertically rotating heating pipes, and the two ends of the heating oil pipe are respectively connected to the oil inlet pipe 5 and the oil outlet pipe 6.

[0021] The connecting plate 2 of the present application is mounted on the trestle. A telescopic cylinder 3 is disposed below the connecting plate 2. The telescopic cylinder 3 is capable of vertical expansion and contraction, and is used to insert the mobile heater of the present application into the train tank 1 through the manhole, or to remove the mobile heater from the train tank. The specific location of the connecting plate on the trestle is determined based on actual needs and is within the routine skills of those skilled in the art.

[0022] The telescopic mechanism of the present application is a telescopic cylinder 3, and a mobile heater is connected to the piston rod of the telescopic cylinder. Through the action of the telescopic cylinder, the mobile heater is used to extend into the train tank from the manhole of the train tank or to be pulled out from the train tank.

[0023] The heating oil pipe of this application is a frame structure formed by vertically coiled heating pipes. The ends of the heating oil pipes are connected to the oil inlet pipe 5 and the oil outlet pipe 6 respectively. Specifically, the heating pipes are coiled back and forth in the vertical direction. The coiled heating pipes have an overall cylindrical or square cylindrical shape, with gaps between adjacent heating pipes for the passage of the heated material. The cross-section of the vertically coiled heating pipes is circular or square.

[0024] In this application, a hose reel (not shown) is provided on both the oil inlet and outlet pipes. When the piston rod of the telescopic cylinder extends downward, the oil inlet or outlet pipe on the hose reel simultaneously extends to coordinate with the downward movement of the heated oil pipe. When the piston rod of the telescopic cylinder retracts upward, the hose reel winds the oil inlet or outlet pipe to prevent accumulation. The hose reel in this application is commercially available, and the specific model can be selected according to needs.

[0025] The present application also includes a stirring device assembly, which includes a stirring motor and an agitator. The stirring motor is mounted at the lower end of the piston rod, and the output shaft of the stirring motor is connected to the agitator. The agitator is disposed within the frame structure. The agitator stirs the heating medium, thereby increasing the flow velocity, accelerating heat transfer, and improving heating efficiency.

[0026] In this application, a heating coil (not shown in the figure) is provided at the bottom of the train tank. The heating coil is provided with a steam inlet and a steam outlet at the lower rear end of the train tank. The steam inlet is connected to the steam source through a pipeline, and the steam outlet is connected to the steam loop pipeline. This structure is a conventional setting of existing train tanks and will not be described in detail here.

[0027] In other embodiments of the present application, in addition to the technical solutions of Example 1, a movable motor (not shown) is disposed below the connecting plate to drive the telescopic mechanism to move along the slide rails on the connecting plate. In this embodiment, the specific structure and method for the movable motor to drive the telescopic mechanism to move along the slide rails on the connecting plate are referenced to similar structures of existing gantry cranes, machine tools, etc. Those skilled in the art can select any one of these structures based on existing technologies. Therefore, this application does not provide a detailed description of the relevant structures, but this does not constitute an inadequate disclosure of this application.

[0028] The telescopic cylinder of the present application moves on the slide rail of the connecting plate through a sliding block. The sliding block includes a slider body and two parallel mounting frames arranged on the slider body. A roller is provided on each mounting frame. The two rollers are respectively arranged on both sides of the slide rail. The above structure is a conventional technology in the existing sling field. The telescopic cylinder is installed on the lower surface of the slider body.

[0029] The working principle of this utility model:

[0030] When the train tank needs to be heated, the telescopic mechanism is started, the piston rod of the telescopic cylinder moves downward, and the mobile heater is extended into the train tank through the manhole of the train tank. The valve of the hot oil pipeline is opened, and the heating oil heats the medium in the train tank through the heating oil pipe of the mobile heater. At the same time, the steam valve of the original internal heating coil on the train tank is opened to heat the medium at the bottom of the train tank. If a stirring component is provided, it can also be opened at the same time to stir the flow of the medium and improve the heating efficiency. After the heating is completed, the heating oil valve and the steam valve are closed, and the piston rod of the telescopic cylinder moves upward to pull the mobile heater out of the train tank.

[0031] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
