Description

Technical Field

[0001] The utility model belongs to the technical field of thermal insulation containers, and in particular relates to a vacuum thermal insulation container connecting pipeline. Background Art

[0002] As the name implies, an insulated container is a container that can limit the heat transfer of substances. Its characteristics are that heat will not be lost and no heat exchange will occur with the outside world. This container is composed of two heat exchange surfaces that are far apart along the normal direction. The volume of the gas inside remains unchanged and will not leak due to changes in air pressure. The temperature inside the insulated container does not exchange heat with the external environment, so it can prevent energy waste while keeping the substance at a certain temperature. When conducting gas between the insulated container and the external connection structure, a connecting pipe needs to be applied.

[0003] In order to ensure the air filtering effect inside the pipe, the current connecting pipe is equipped with a filtering structure inside to prevent the dust in the airflow in the external connecting structure from entering the insulated container. Although it has a certain air filtering effect, the filtering structure is not easy to disassemble and the internal air filter net is not easy to clean, resulting in a significant reduction in the filtering effect after long-term use. The overall pipe is not practical. Therefore, a vacuum insulated container connecting pipe is urgently needed to solve the above problems. Utility Model Content

[0004] The purpose of the utility model is to solve the problem that in order to ensure the air filtering effect in the current connecting pipes, a filtering structure is arranged inside, so that the dust in the airflow in the external connecting structure cannot enter the insulated container. Although the pipe has a certain air filtering effect, the filtering structure is not easy to disassemble, and the internal air filter net is not easy to clean, resulting in a significant reduction in the filtering effect after long-term use and the overall pipe is not practical. A vacuum insulated container connecting pipe is proposed.

[0005] In order to achieve the above-mentioned purpose, the utility model adopts the following technical scheme: a vacuum insulated container connecting pipeline, including a connecting pipe, a sealing connecting sleeve is provided at one end of the connecting pipe, an inner step is provided on the inner surface of the connecting pipe, a built-in filtering mechanism is provided on the inner step, the built-in filtering mechanism includes a mounting plate, the mounting plate is slidably connected to the inner surface of the connecting pipe, the outer surface of the mounting plate is provided with an outer groove, and a heat expansion sealing gasket is embedded and installed in the outer groove.

[0006] As a further description of the above technical solution:

[0007] The interior of the heat expansion seal is filled with a plurality of heat expansion particles, the outer surface of the heat expansion seal is in close contact with the inner surface of the connecting pipe, and two side connecting rods are fixedly mounted on the outer wall of one side of the mounting plate, and the two side connecting rods are arranged parallel to each other.

[0008] As a further description of the above technical solution:

[0009] A side hook plate is fixedly mounted on one end of the side connecting rod, and an air filter net is arranged inside the mounting plate.

[0010] As a further description of the above technical solution:

[0011] A rotating hole is arranged on one side outer wall of the air filter net, and a wind cleaning component is rotatably installed in the rotating hole. The wind cleaning component comprises a mounting shaft, and the mounting shaft is rotatably installed in the rotating hole.

[0012] As a further description of the above technical solution:

[0013] An outer mounting roller is fixedly mounted on one end of the mounting shaft, an oblique fan blade is fixedly mounted on the outer surface of the outer mounting roller, and a mounting plate shell is fixedly mounted on the outer surface of the mounting shaft.

[0014] As a further description of the above technical solution:

[0015] An internal spring is arranged inside the mounting plate shell, a cleaning side plate is fixedly mounted on one end of the internal spring, and one end of the cleaning side plate is in contact with the air filter screen.

[0016] In summary, due to the adoption of the above technical solution, the beneficial effects of the utility model are:

[0017] 1. In the utility model, a built-in filtering mechanism is provided in the pipeline. After the insulated container is connected to the external structure through the connecting pipe, the hot air flow of the external structure can enter the insulated container through the connecting pipe, and the dust entrained in the hot air flow can be effectively filtered by the air filter net to prevent the dust from entering the insulated container. At this time, due to the circulation of gas in the connecting pipe, the inclined fan blades can be affected by the wind force and rotate, and the cleaning side plates can rotate synchronously, driving the cleaning side plates to rotate synchronously. The cleaning side plates can be stably contacted with the air filter net under the action of the built-in spring to achieve synchronous cleaning of the dust on the outer surface of the air filter net, thereby avoiding the clogging of the filter holes of the air filter net. Through this design, not only can the stable conduction of the air flow be completed, but also the hot air flow can be well filtered during the conduction to prevent the dust from entering the insulated container. At the same time, the synchronous cleaning of the air filter net can be achieved synchronously to avoid the clogging of the pores of the air filter net. While ensuring the filtering effect of the air filter net, the air permeability of the air filter net is ensured, thereby improving the actual application effect of the overall pipeline.

[0018] 2. In the utility model, the built-in filter mechanism is designed to be quickly detachable. When the built-in filter mechanism needs to be cleaned, the built-in filter mechanism can be directly hooked out through the side hook plate through the hook plate. The disassembly is convenient and quick. At the same time, due to the high temperature in the connecting pipe, the heat expansion particles in the heat expansion sealing gasket will expand, thereby improving the contact effect between the heat expansion sealing gasket and the inner surface of the connecting pipe, thereby improving the stability of the built-in filter mechanism in the connecting pipe. Even if the air flow rate through the pipeline is increased, the built-in filter mechanism can still maintain stability and maintain its use effect. BRIEF DESCRIPTION OF THE DRAWINGS

[0026] An air filter net 33 is arranged inside the mounting plate 32, and a rotating hole is arranged on the outer wall of one side of the air filter net 33, and a wind cleaning component 34 is rotatably installed in the rotating hole. The wind cleaning component 34 includes a mounting shaft 346, and the mounting shaft 346 is rotatably installed in the rotating hole. An outer mounting roller 345 is fixedly installed at one end of the mounting shaft 346, and an inclined fan blade 344 is fixedly installed on the outer surface of the outer mounting roller 345. A mounting plate shell 343 is fixedly installed on the outer surface of the mounting shaft 346, and an internal spring 342 is arranged inside the mounting plate shell 343, and a cleaning side plate 341 is fixedly installed on one end of the internal spring 342, and one end of the cleaning side plate 341 is in contact with the air filter net 33.

[0027] The specific implementation method is as follows: after the insulated container is connected to the external structure through the connecting pipe 1, the hot air flow of the external structure can enter the insulated container through the connecting pipe 1, and the dust entrained in the hot air flow can be effectively filtered by the air filter net 33 to prevent the dust from entering the insulated container. At this time, due to the circulation of gas in the connecting pipe 1, the inclined fan blades 344 can be affected by the wind force and rotate, and the cleaning side plate 341 can rotate synchronously, driving the cleaning side plate 341 to rotate synchronously. The cleaning side plate 341 can be stably contacted with the air filter net 33 under the action of the built-in spring 342, thereby realizing the synchronous cleaning of the dust on the outer surface of the air filter net 33, thereby preventing the filter holes of the air filter net 33 from being blocked.

[0028] The interior of the heat expansion sealing gasket 31 is filled with a plurality of heat expansion particles, and the outer surface of the heat expansion sealing gasket 31 is in close contact with the inner surface of the connecting pipe 1. Two side connecting rods 35 are fixedly installed on the outer wall of one side of the mounting plate 32. The two side connecting rods 35 are arranged parallel to each other, and a side hook plate 36 is fixedly installed at one end of the side connecting rod 35.

[0029] The specific implementation method is as follows: when the built-in filter mechanism 3 needs to be cleaned, the built-in filter mechanism 3 can be directly hooked out through the side hook plate 36 through the hook plate, and the disassembly is convenient and quick. At the same time, due to the high temperature in the connecting pipe 1, the heat expansion particles in the heat expansion sealing gasket 31 will expand, thereby improving the contact effect between the heat expansion sealing gasket 31 and the inner surface of the connecting pipe 1, thereby improving the stability of the built-in filter mechanism 3 in the connecting pipe 1. Even if the air flow rate through the pipeline is increased, the built-in filter mechanism 3 can still maintain stability.

[0030] Working principle: After the insulated container is connected to the external structure through the connecting pipe 1, the hot air flow of the external structure can enter the insulated container through the connecting pipe 1, and the dust entrained in the hot air flow can be effectively filtered by the air filter 33 to prevent the dust from entering the insulated container. At this time, due to the circulation of gas in the connecting pipe 1, the inclined fan blades 344 can be affected by the wind and rotate, and the cleaning side plate 341 can rotate synchronously, driving the cleaning side plate 341 to rotate synchronously. The cleaning side plate 341 can stably contact with the air filter 33 under the action of the built-in spring 342, so as to achieve the purpose of cleaning the outside of the air filter 33. The surface dust is cleaned synchronously to avoid clogging of the filter holes of the air filter net 33; when the built-in filter mechanism 3 needs to be cleaned, the built-in filter mechanism 3 can be directly hooked out through the side hook plate 36 through the hook plate, and the disassembly is convenient and quick. At the same time, due to the high temperature in the connecting pipe 1, the heat expansion particles in the heat expansion sealing gasket 31 will expand, thereby improving the contact effect between the heat expansion sealing gasket 31 and the inner surface of the connecting pipe 1, thereby improving the stability of the built-in filter mechanism 3 in the connecting pipe 1. Even if the air flow rate through the pipeline is increased, the built-in filter mechanism 3 can still maintain stability.
