Description

Technical Field

[0002] A heating pipeline is a necessary connecting pipeline in a heating device, which can transport hot water or warm air as a heating medium, reduce heat loss during transportation, and thus achieve the purpose of energy conservation. This solution specifically relates to a heating pipeline for an energy-saving heating device. The existing heating pipeline only conducts heat preservation by wrapping with heat-insulating materials. Therefore, the heat preservation effect is too good. And when the ambient temperature is too low, if hot water is transported inside, the farther the transportation distance, the greater the heat loss, and it is easy to freeze inside. At the same time, the transported heating medium cannot be filtered, and impurities are easy to accumulate after transportation, blocking the pipeline and equipment. Content of the Utility Model

[0003] The main purpose of the utility model is to provide a heating pipeline for an energy-saving heating device, which can effectively solve the problems in the background technique.

[0004] To achieve the above purpose, the technical solution adopted by the utility model is as follows:

A vacuum cavity is arranged in a circle between the conveying inner pipe and the isolation inner pipe and at the position between the two head rings.

[0006] As a further solution of the utility model, the same liquid outlet pipe is fixedly installed through the top pipe walls of the protective outer pipe and the isolation inner pipe near the rear end, and the same liquid inlet pipe is fixedly installed through the bottom pipe walls of the protective outer pipe and the isolation inner pipe near the front end.

Detailed Embodiments

[0018] In order to make the technical means, creative features, achieved purposes and effects of the present utility model easy to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0019] Such as Figures 1 - 4As shown in the figure, a heating pipeline for an energy-saving heating device includes a protective outer pipe 1. A filtering component 7 is installed at the rear end of the protective outer pipe 1. A plurality of inner supports 5 are fixedly welded to the inner ring of the protective outer pipe 1 near the front and rear ends. An isolation inner pipe 2 is fixedly welded between the inner supports 5 at the front and rear ends. A heat-insulating filler layer 4 is filled between the isolation inner pipe 2 and the protective outer pipe 1. Head rings 6 are fixedly welded to the inner ring of the isolation inner pipe 2 near the front and rear ends. A conveying inner pipe 3 is fixedly welded between the two head rings 6. A vacuum cavity 10 is arranged in a circle between the conveying inner pipe 3 and the isolation inner pipe 2 and between the two head rings 6.

[0020] A liquid outlet pipe 8 is fixedly installed at the same position through the top pipe walls of the protective outer pipe 1 and the isolation inner pipe 2 near the rear end. A liquid inlet pipe 9 is fixedly installed at the same position through the bottom pipe walls of the protective outer pipe 1 and the isolation inner pipe 2 near the front end. High-temperature liquid or gas is introduced into the vacuum cavity 10 through the liquid inlet pipe 9. When the high-temperature liquid or gas overflows from the liquid outlet pipe 8, the vacuum cavity 10 is filled with high-temperature liquid or gas, which can prevent the heating medium in the conveying inner pipe 3 from being frozen at low temperatures.

[0021] The filtering component 7 includes an adapter kit 701. A guiding mark 702 is arranged in the middle at the top of the adapter kit 701. Heat-insulating cotton 703 is filled on both sides inside the adapter kit 701. A filter screen 704 is fixedly installed at the inner ring of the adapter kit 701 near the front end. A stop valve 705 is fixedly installed in the middle at the bottom of the adapter kit 701. An impurity hopper 706 is fixedly installed at the bottom of the stop valve 705. A stop valve 707 is fixedly installed at the bottom of the impurity hopper 706. An air pressure balance valve 708 is fixedly installed through the top of the impurity hopper 706 near the rear. By setting the filtering component 7, it is convenient to filter the heating medium and reduce the impurity content.

[0022] The conveying inner pipe 3 and the adapter kit 701 are sealed and bonded with waterproof glue, and the protective outer pipe 1 and the adapter kit 701 are fixedly welded, which is convenient for the connection between the filtering component 7 and the conveying inner pipe 3 and the protective outer pipe 1.

[0023] Both the liquid outlet pipe 8 and the liquid inlet pipe 9 are communicated with the inside of the vacuum cavity 10, which is convenient for adding and discharging high-temperature liquid or gas and for evacuating the vacuum cavity 10.

[0024] The stop valve 705 is communicated with the inside of the adapter kit 701. Through the stop valve 705, it is convenient to block the bottom of the adapter kit 701.

[0025] It should be noted that the utility model is a heating pipe for energy-saving heating equipment. When in use, the heating pipe is first installed, and the components are connected and supported by the inner support 5. During installation, the heating medium flows in the direction of the guide mark 702. The heating medium is the heating air or hot water required for heating. The inner part is protected by the protective outer pipe 1. When the heating medium is transported, it enters from the rear end of the adapter kit 701, is filtered by the filter 704, and then enters the transport inner pipe 3 for transport. At the same time, the filtered impurities fall into the impurity bucket 3.

[0026] During the heating medium transportation process, the heat preservation cotton 703 and the heat preservation filler layer 4 are used for heat preservation, and the vacuum environment of the vacuum chamber 10 is used for heat insulation, so as to further optimize the heat preservation effect;

[0027] When the temperature of the transport environment is excessive, high-temperature liquid or gas is introduced into the vacuum chamber 10 through the liquid inlet pipe 9. When the high-temperature liquid or gas overflows from the liquid outlet pipe 8, the vacuum chamber 10 is filled with high-temperature liquid or gas to prevent the heating medium in the transport inner pipe 3 from being frozen at low temperatures. When vacuum insulation is required, after the high-temperature liquid or gas is discharged, the liquid outlet pipe 8 and the liquid inlet pipe 9 are connected to an external vacuum pump to keep the vacuum chamber 10 in a vacuum state.

[0028] After closing the stop valve 1 705, open the air pressure balance valve 708 to balance the air pressure inside the impurity hopper, and then open the stop valve 2 707 to allow the impurities inside the impurity hopper 706 to be discharged through the stop valve 2 707, so as to discharge the filtered impurities without interfering with the transportation of the heating medium.

[0029] The above shows and describes the basic principle and main features of the utility model and the advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only for explaining the principle of the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, which fall within the scope of the utility model to be protected.
