[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 2As shown, the present application provides a train tank forced raw material circulation heating device, including a moving device. The moving device of the present application is a moving cylinder 10, which is installed on the lower surface of the mounting seat 11. In the present application, the mounting seat 11 can be installed on, for example, a trestle, or other moving devices. The mounting seat is a conventional plate structure. The present technical solution does not involve improvements to the mounting seat. Those skilled in the art can set the mounting seat at the corresponding position of the trestle or on a mobile trolley-like device according to conventional choices. The specific mobile trolley is a conventional trolley device. If a mobile trolley-type device is used, it is only necessary to install a support frame on the trolley, and then install the mounting seat on the mounting support frame. However, the present technical solution preferably installs the mounting seat on the trestle, so that the existing device of the trestle can be used or moved relative to it, etc. Those skilled in the art can use existing technology to arbitrarily install or design the mounting seat according to needs, which does not affect the implementation of the technical solution of the present application.

[0021] The movable cylinder 10 is mounted on the lower surface of the mounting base in order to allow the movable cylinder to drive the other parts to move up and down. As for the model of the movable cylinder, those skilled in the art can make a commercial choice based on actual needs. The lower end of the piston rod of the movable cylinder is fixedly mounted on the telescopic guide mechanism 1, and the telescopic guide mechanism is driven to move up and down by the telescopic movement of the movable cylinder. At least two guide rods 12 are fixed to the telescopic guide mechanism. In this embodiment, two or four guide rods can be selected. The purpose is to avoid the problem of offset when the movable cylinder drives the telescopic guide mechanism to move up and down. The upper end of the guide rod moves through the mounting base.

[0022] A pump 2 is mounted on the upper surface of the telescopic guide mechanism 1, connected to a power source via a wire. This is conventional technology. Two hose holes are provided on the telescopic guide mechanism, through which a feed hose 6 and a discharge hose 7 pass. A hose connection portion 3 is provided on the lower surface of the telescopic guide mechanism. Within this hose connection portion 3 are located a feed hose connected to the pump inlet and a discharge hose connected to the pump outlet. Below this hose connection portion are a feed pipe 8 and a discharge pipe 9. The upper end of the feed pipe extends into the hose connection portion and connects to the feed hose. The upper end of the discharge pipe flexibly extends into the hose connection portion and connects to the discharge hose.

[0023] A telescopic cylinder (not shown in the figure) is provided in the hose connecting portion 3 , and the cylinder rod of the telescopic cylinder is fixedly connected to the discharge pipe. Specifically, the fixed connection method can be a connection method using existing technology.

[0024] In this application, the length of the portion of the discharge hose 7 disposed in the hose connection portion is greater than the upper and lower lengths of the inner cavity of the hose connection portion, and is disposed in the hose connection portion by bending or spiraling. This structure ensures the expansion and contraction of the discharge hose.

[0025] A temperature sensor or infrared sensor (not shown in the figure) is provided at the lower end of the feed pipe. The temperature sensor or infrared sensor is electrically connected to the controller, and the controller is electrically connected to the moving cylinder.

[0026] Working principle:

[0027] After the train tank is docked at the corresponding position, this embodiment is explained using the docking trestle as an example. By moving the relevant components of the trestle, the mounting seat is synchronously driven to move above the manhole of the train tank. Then, the moving cylinder is activated, and the piston rod of the moving cylinder extends downward, driving the telescopic guide mechanism to move downward at the same time, so that the feed pipe and the discharge pipe are both inserted into the train tank through the manhole. When the temperature sensor or infrared sensor set at the lower end of the feed pipe detects the position of the heating coil at the bottom of the train tank, a feedback signal is sent to the moving cylinder, causing it to stop moving downward. At this time, the feed pipe is located at the high-temperature medium at the heating coil of the train tank, and the discharge pipe is located at the low-temperature medium of the train tank. The pump is then started, and the pump extracts the heated medium through the feed pipe and then injects it back into the low-temperature medium of the train tank through the discharge pipe, performing forced convection heat exchange. After a certain period of convection heat exchange, the telescopic cylinder can be activated to drive the discharge pipe downward to bring the hot medium extracted by the pump closer to the low-temperature medium, thereby improving the heat exchange effect.

[0028] 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.
