Technical Field

[0001] This utility model belongs to the field of gas cylinder filling technology, and in particular relates to an automatic filling device. Background Technology

[0002] In the field of industrial gas filling, traditional equipment generally suffers from insufficient sealing and weak safety protection. While traditional open-type filling devices (such as CN215862858U) achieve tank height adaptation through lifting mechanisms, when filling flammable and explosive gases (such as hydrogen and LPG), a failure in the sealing of the filling pipe connection will directly lead to the leakage of flammable gases and cause an explosion. To address these shortcomings, we propose an automatic filling device. Utility Model Content

[0003] The purpose of this utility model is to provide an automatic filling device to solve the technical problems mentioned in the background art.

[0004] To achieve the above objectives, the specific technical solution of this utility model is as follows: an automatic filling device, comprising a protective frame, an inflation mechanism, and a protective mechanism;

[0028] like Figure 1-4 As shown, the present invention provides an automatic filling device, which includes a protective frame, an inflation mechanism, and a protective mechanism.

[0029] The protective frame consists of four uprights 10 and a protective cover installed inside them. The protective cover includes a fixed cover 11, a movable cover 12, and a sealing frame 13. The fixed cover 11 is fixedly installed on the inner wall of the uprights 10. The movable cover 12 is slidably connected to the fixed cover 11 through a drive assembly. The sealing frame 13 is embedded in the foundation of the installation site and has an insertion slot for the movable cover 12 to be inserted. Each of the four inner side walls of the fixed cover 11 is fixedly installed with a baffle 14. Each of the four outer surfaces of the movable cover 12 is fixedly provided with a rubber sealing plate 15 that cooperates with the baffle 14.

[0030] The drive assembly includes a cylinder 30 and a guide component. The cylinder 30 is fixed to the inner top wall of the fixed cover 11 and its telescopic end is fixed to the inner side wall of the movable cover 12. The guide component includes four guide posts 31 and a guide ring 32 fixed to the inner side wall of the movable cover 12. The guide posts 31 and the guide ring 32 form a sliding pair. When the cylinder 30 drives the movable cover 12 to move, the guide ring 32 will slide on the surface of the guide posts 31 to ensure the vertical movement accuracy of the movable cover 12.

[0031] The movable cover 12 and the fixed cover 11 form a dynamic sealing space. When the cylinder 30 drives the movable cover 12 to move down, the rubber sealing plate 15 and the baffle 14 form a planar seal. The lower end of the movable cover 12 and the insertion groove on the sealing frame 13 form a plug-in three-dimensional seal, achieving double sealing protection and preventing gas leakage.

[0032] The inflation mechanism includes a support frame 20, multiple sets of gas supply pipes 21, and inflation pipe connectors 22. The support frame 20 is fixed to the inner top wall of the fixed cover 11. The gas supply pipes 21 are equidistantly arranged on the inner wall of the support frame 20. One end of the gas supply pipe 21 is connected to the inflation pipe connector 22, and the other end extends to the top of the fixed cover 11 and is provided with a gas supply pipe connector 23. The inflation pipe is installed on the inflation pipe connector 22, and the other end of the inflation pipe is connected to the inflation-specific connector. Then, the gas supply pipe of the external automatic gas cylinder filling system is connected to the gas supply pipe connector 23. After the operator places the gas cylinder rack containing the gas cylinder under the protective cover, the operator can connect the inflation-specific connector to the gas cylinder and use the external automatic gas cylinder filling system to automatically inflate the gas cylinder. The inflation-specific connector and the external automatic gas cylinder filling system are existing technologies and will not be described in detail. The inflation-specific connector can be selected according to the model of the gas cylinder.

[0033] The protective mechanism consists of an inert gas conveying component and a forced gas exhaust component. The forced gas exhaust component includes an exhaust pipe 50, a fan 51, and a gas monitor 52. The exhaust pipe 50 is fixedly installed on the upper end of the fixed cover 11 and penetrates the top wall of the fixed cover 11. The fan 51 is located at the outlet of the exhaust pipe 50, and the exhaust end of the fan 51 is connected to an external activated carbon adsorption tower. The gas monitor 52 is fixedly installed on the upper surface of the fixed cover 11 and integrates an audible and visual alarm. The monitoring probe of the gas monitor 52 extends into the interior of the protective cover. The monitoring probe has... There are two gas detectors, one installed on the top wall inside the fixed cover 11 and the other on the bottom inside the movable cover 12. Both the gas detector 52 and the activated carbon adsorption tower are existing technologies and will not be described in detail. The appropriate gas detector 52 can be selected according to the different gases being filled. When the gas cylinder is being filled, the gas detector 52 can monitor the gas inside the protective cover. If a gas leak is detected, the fan 51 can be turned on to discharge the gas from the protective cover and adsorb it using the external activated carbon adsorption tower, thus preventing personnel from inhaling the gas and preventing gas accumulation from causing an explosion.

[0034] The inert gas delivery component consists of an inert gas storage bottle 40, a flexible delivery pipe 41, a connecting pipe 42, an exhaust nozzle 43, and a solenoid valve 44. The connecting pipe 42 is fixed to the inner wall of the movable cover 12, and the solenoid valve 44 is located on the surface of the connecting pipe 42. One end of the delivery pipe 41 is connected to the inert gas storage bottle 40, and the other end is connected to the connecting pipe 42. The connecting pipe 42 releases inert gas into the protective cover through the exhaust nozzle 43. The solenoid valve 44 controls the release of inert gas. When the gas monitor 52 detects a gas leak, the solenoid valve 44 can be opened to introduce inert gas into the protective cover, thereby suppressing gas explosion.

[0035] It is understood that this utility model has been described through some embodiments, and those skilled in the art will recognize that various changes or equivalent substitutions can be made to these features and embodiments without departing from the spirit and scope of this utility model. Furthermore, under the teachings of this utility model, these features and embodiments can be modified to adapt to specific situations and materials without departing from the spirit and scope of this utility model.
