Description

Technical Field

[0001] The utility model belongs to the technical field of tanker transportation, and particularly relates to a double heating system for train tanks. Background Art

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

[0003] At the current stage, after the train tank arrives at the destination, high-temperature steam is introduced through the heating pipes at the bottom for heating operation. Usually, it takes 8 - 10 hours of heating time, and the heating rate is slow, resulting in waste of energy and time. Therefore, how to improve the heating efficiency has been a topic that technicians in this field have been researching. Summary of the Utility Model

[0007] The heating coil is provided with a steam inlet and a steam outlet at the lower part of the rear end of the train tank, wherein the steam inlet is connected to the air inlet of the heating coil, and the steam outlet is connected to the air outlet of the heating coil;

[0008] The mobile heater includes a telescopic mechanism and a steam heating pipe connected to the telescopic mechanism. The air inlet of the steam heating pipe is connected to a steam source, and the air outlet of the steam heating pipe is connected to a steam return pipeline.

[0009] Furthermore, it also includes a mounting seat. The mounting seat is installed on the trestle, and a mobile motor is arranged below the mounting seat. The mobile motor drives the telescopic mechanism to move along the slide rail on the mounting seat.

[0010] Furthermore, the telescopic mechanism is a telescopic cylinder, and the lower end of the piston rod of the telescopic cylinder is connected to the steam heating pipe.

[0011] Furthermore, the telescopic cylinder moves on the slide rail of the mounting seat through a sliding block. The sliding block includes a slider body and two parallel mounting brackets arranged on the slider body. One roller is arranged on each mounting bracket, and the two rollers are respectively arranged on both sides of the slide rail.

[0012] Further, the steam outlet of the heating coil is connected to the air inlet of the steam heating pipe through a pipeline, and the air outlet of the steam heating pipe is connected to the steam circuit pipeline.

[0013] Further, the steam heating pipe is of a coil structure.

[0014] The beneficial effects of the present utility model are as follows:

[0015] With the heating coil arranged at the bottom inside the railway tank and the movable heater arranged movably inside the railway tank in this technical solution, the inside of the railway tank can be heated by steam while the bottom heating coil of the railway tank itself is heating, enabling the medium inside the railway tank to be heated rapidly. While improving the heating efficiency, the energy utilization rate is also improved. Description of the Drawings

[0019] The technical solution of the present utility model will be described in detail below with reference to the drawings. The following embodiments are merely exemplary and can only be used to explain and illustrate the technical solution of the present utility model, rather than being construed as a limitation of the technical solution of the present utility model.

[0020] As Figure 1 shown, the present application provides a double - heating system for railway tanks, including a heating coil arranged at the bottom inside the railway tank and a movable heater arranged movably inside the railway tank.

[0021] The present application includes a mounting seat 5, which is installed on the trestle. A moving motor (not shown in the figure) is arranged below the mounting seat, and the moving motor drives the telescopic mechanism to move along the slide rail on the mounting seat. The specific position of the mounting seat on the trestle is determined according to actual needs, and this part belongs to the conventional technology of those skilled in the art. For the specific structure and manner in which the moving motor drives the telescopic mechanism to move along the slide rail on the mounting seat, refer to the relevant similar structures of existing gantry cranes, machine tools, etc. Those skilled in the art can choose any one according to the existing technology. Therefore, the present application does not describe the relevant structure in detail, but it cannot be considered that the disclosure of the present application is insufficient.

[0022] The telescopic mechanism of the present application is a telescopic cylinder 4. The lower end of the piston rod of the telescopic cylinder is connected to the steam heating pipe. Through the action of the telescopic cylinder, the steam heating pipe is used to extend into the railway tank 2 from the manhole of the railway tank or be pulled out from inside the railway tank.

[0023] The telescopic cylinder of the present application moves through a sliding block on the slide rail of the mounting seat. The sliding block includes a slider body and two parallel mounting brackets provided on the slider body. A roller is provided on each mounting bracket, and the two rollers are respectively arranged on both sides of the slide rail. The above structure is a conventional technology in the field of current lifting appliances. The telescopic cylinder is installed on the lower surface of the slider body.

[0024] The heating coil 1 is provided with a steam inlet and a steam outlet at the lower part of the rear end of the train tank 2, wherein the steam inlet is connected to the air inlet of the heating coil, and the steam outlet is connected to the air outlet of the heating coil.

[0025] The mobile heater includes a telescopic mechanism and a steam heating pipe 3 connected to the telescopic mechanism. The air inlet of the steam heating pipe is connected to a steam source through an air inlet pipe 6, and the air outlet of the steam heating pipe is connected to a steam circuit pipeline through an air outlet pipe 7.

[0026] In other embodiments of the present application, the steam outlet of the heating coil is connected to the air inlet of the steam heating pipe through a pipeline, and the air outlet of the steam heating pipe is connected to the steam circuit pipeline. In this way, the steam flowing out from the heating coil at the bottom of the train tank heats the medium at other parts in the train tank through the steam heating pipe, which not only improves the heating efficiency but also avoids the waste of steam flowing out from the heating coil due to the reduction of temperature and pressure and still cannot be used. However, the steam temperature is still relatively high at this time, and direct release will cause energy waste. This embodiment saves energy by recycling the low-temperature and low-pressure steam.

[0027] In the present application, the steam heating pipe is of a coil structure.

[0028] Working principle:

[0029] When the train tank needs to be heated, start the mobile motor. After the mobile motor drives the telescopic cylinder to move above the manhole of the train tank and stops, then start the telescopic cylinder to extend the steam heating pipe into the train tank through the manhole of the train tank. Connect the steam source pipeline and the return air pipeline to the steam inlet and the steam outlet of the heating coil outside the train tank, and according to needs, connect the steam source pipeline to the air inlet of the steam heating pipe, and connect the air outlet of the steam heating pipe to the return air pipeline through a pipeline. In other embodiments, it is also possible to choose to connect the steam outlet of the heating coil to the air inlet of the steam heating pipe through a pipeline, open the corresponding valve to heat the train tank, and after the heating is completed, close the valve and start the telescopic cylinder to pull out the steam heating pipe from the train tank.

[0030] The above are only the preferred specific embodiments of the present utility model, but the protection scope of the present utility model is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present utility model, according to the technical solution and the inventive concept of the present utility model, makes equivalent substitutions or changes, and all should be covered within the protection scope of the present utility model.
