Description

Technical Field

[0001] This application relates to the field of gas cylinder filling technology, and in particular to a gas cylinder filling device. Background Technology

[0002] The current gas cylinder filling process is as follows: The gas cylinder is unloaded onto the filling platform; the cylinder counting worker counts the cylinders on-site and writes a cylinder counting slip by hand; the ticket office issues an invoice based on the cylinder counting data and prints a paper invoice; after the ticket office receives payment, it issues an instruction to the electronic scale; the filling device begins to fill the gas cylinder. The gas cylinder is placed on the electronic scale during filling, and the gas valve of the gas cylinder is connected to the filling pipe of the filling device; the weighing pan of the electronic scale is usually made of iron or stainless steel. When the filling device fills the gas cylinder, it cannot accurately align with the gas cylinder valve, so manual operation and inspection are required.

[0003] A search revealed that CN215215730U discloses an automatic cylinder filling device. The device is installed at the filling point of an automatic cylinder filling and testing line via a cylinder positioning plate. A cylinder clamp holds the cylinder and places it on the filling platform. The downward force of the cylinder on the guide sliding column causes the filling mechanism to move downwards, bringing the filling device, fixed to the lower end of the movable plate, into contact with the cylinder nozzle. The conical cylinder-shaped filling device precisely aligns with the cylinder nozzle. Then, the upward force of the filling cylinder on the guide column causes the movable plate to move upwards, inserting the filling nozzle into the cylinder nozzle.

[0004] Regarding the aforementioned technologies, the inventors believe that the following technical defects exist and require improvement:

[0005] When filling a gas cylinder, as high-pressure gas is poured into a low-pressure cylinder, the gas molecules collide continuously inside the cylinder, increasing their kinetic energy and thus raising the gas temperature. The faster the filling speed, the higher the gas temperature will be. Most traditional devices do not have relevant cooling equipment. If the pressure exceeds the pressure that the gas cylinder can withstand, it will cause the gas cylinder to rupture, posing a high safety risk. Utility Model Content

[0006] This application provides a gas cylinder filling device to improve the following technical problems:

[0007] Traditional devices often lack cooling equipment. If the pressure exceeds the cylinder's tolerance, it can cause the cylinder to rupture, posing a high safety risk.

[0008] This application provides a gas cylinder filling device, which adopts the following technical solution:

[0009] A gas cylinder filling device includes a gas cylinder body. A cooling-type filling mechanism is provided on the outside of the gas cylinder body. The cooling-type filling mechanism includes a worktable, a movable support, an air pump direct connection pipe, a support frame, a nozzle, a positioning plate, and a liquid storage tank. The positioning plate is rotatably connected to the top of the worktable. The movable support is movably connected to the outside of the worktable. The air pump direct connection pipe passes through the outside of the movable support and is fixedly connected to the air inlet end of the gas cylinder body. The support frame is symmetrically distributed on both sides of the positioning plate. The nozzle is threadedly connected to the top of the support frame. The liquid storage tank is located on the top outside of the worktable. A lifting component is also provided on the inner side of the movable support.

[0010] In one feasible technical solution of this application, the lifting assembly includes a stepper motor, a threaded rod, and a linear shaft. The motor shaft of the stepper motor is fixedly connected to the top of the threaded rod via a coupling. The threaded rod is threaded onto the inner side of the movable bracket. The linear shaft passes through the interior of the movable bracket and is fixedly connected to the inner wall of the worktable.

[0011] In one feasible technical solution of this application, the interior of the movable bracket is provided with threaded grooves and through holes that are adapted to the dimensions of the threaded rod and the linear shaft.

[0012] In one feasible technical solution of this application, the bottom of the support frame is further provided with a water pump, a connecting pipe and a suction pipe. One side of the suction pipe passes through the interior of the liquid storage tank and is fixedly connected to the inner surface of the liquid storage tank. The output end of the water pump is fixedly connected to one side of the connecting pipe. The connecting pipe passes through the interior of the support frame and is fixedly connected to the water inlet end of the nozzle.

[0013] In one feasible technical solution of this application, a reduction motor is further provided at the bottom of the positioning disk, and the reduction motor is threadedly connected to the inner side of the bottom of the worktable.

[0014] In one feasible technical solution of this application, the upper end of the positioning disk is further provided with a water storage sleeve and a brush seat. The water storage sleeve is sleeved on the outside of the positioning disk, and the brush seat is fixedly connected to the top of the positioning disk, and the brush surface of the brush seat is slidably connected to the surface of the cylinder body.

[0015] In one feasible technical solution of this application, a limiting groove is also provided in the middle of the positioning disk.

[0016] In summary, this application includes at least one of the following beneficial technical effects:

[0017] 1. Insert the cylinder body into the limiting groove of the positioning plate. Before inflation, connect the air pump direct connection pipe to the air supply pipe of the external air pump. During operation, the stepper motor on the top of the workbench can be automatically started. Its motor shaft drives the threaded rod to rotate. Two sets of linear shafts pass through the movable bracket and limit its position. With the cooperation of the threaded surface of the threaded rod and the lead screw with the built-in thread groove, the movable bracket can move smoothly in the vertical direction along the opening surface of the through hole. According to the specific height of the cylinder body, the air pump direct connection pipe is connected to the air inlet on the top of the cylinder and fastened with a quick connector to prevent air leakage, thus improving the applicability of this device.

[0018] 2. To prevent overheating of the cylinder body caused by high-pressure gas entering the cylinder, this device can pre-fill the storage tank with coolant. During the filling process, the water pumps on both sides are started simultaneously. The liquid inside the storage tank is drawn in through the suction pipe and discharged into the support frame through the connecting pipes on both sides. It flows through the nozzles on both sides and is sprayed out from the nozzle ends, so that the coolant is sprayed on the top of the cylinder body. At the same time, the reduction motor at the lower end of the positioning plate is started. Its motor shaft drives the positioning plate and the outer ring of brush seats to rotate, thereby evenly distributing the surface liquid and completing the overall cooling of the cylinder body. On the other hand, the excess coolant remains in the water storage sleeve under the action of gravity. The bottom electromagnetic discharge valve is activated through the control terminal, so that the coolant inside the water storage sleeve is drawn back into the storage tank for recycling.

[0030] The following is in conjunction with the appendix Figure 1-4 This application will be described in further detail.

[0031] This application discloses a gas cylinder filling device. (Refer to...) Figure 1The gas cylinder filling device includes a gas cylinder body 1. A cooling-type filling mechanism 2 is provided on the outside of the gas cylinder body 1. The cooling-type filling mechanism 2 includes a workbench 21, a movable support 22, an air pump direct connection pipe 23, a support frame 24, a nozzle 25, a positioning plate 26, and a liquid storage tank 27. The positioning plate 26 is rotatably connected to the top of the workbench 21. The movable support 22 is movably connected to the outside of the workbench 21. The air pump direct connection pipe 23 passes through the outside of the movable support 22 and is fixedly connected to the air inlet end of the gas cylinder body 1. The support frame 24 is symmetrically distributed on both sides of the positioning plate 26. The nozzle 25 is threadedly connected to the top of the support frame 24. The liquid storage tank 27 is located on the top outside of the workbench 21. A lifting component 3 is also provided on the inside of the movable support 22.

[0032] The lifting assembly 3 includes a stepper motor 31, a threaded rod 32, and a linear shaft 33. The motor shaft of the stepper motor 31 is fixedly connected to the top of the threaded rod 32 via a coupling. The threaded rod 32 is threaded onto the inner side of the movable bracket 22. The linear shaft 33 passes through the interior of the movable bracket 22 and is fixedly connected to the inner wall of the worktable 21.

[0033] The interior of the movable bracket 22 is provided with threaded grooves 4 and through holes 5 that are adapted to the dimensions of the threaded rod 32 and the linear shaft 33, respectively.

[0034] The bottom of the support frame 24 is also equipped with a water pump 6, a connecting pipe 7 and a suction pipe 8. One side of the suction pipe 8 passes through the interior of the liquid storage tank 27 and is fixedly connected to the inner surface of the liquid storage tank 27. The output end of the water pump 6 is fixedly connected to one side of the connecting pipe 7. The connecting pipe 7 passes through the interior of the support frame 24 and is fixedly connected to the water inlet end of the nozzle 25.

[0035] The bottom of the positioning plate 26 is also equipped with a reduction motor 9, which is threadedly connected to the bottom inner side of the worktable 21.

[0036] The upper end of the positioning plate 26 is also provided with a water storage sleeve 10 and a brush seat 11. The water storage sleeve 10 is sleeved on the outside of the positioning plate 26, and the brush seat 11 is fixedly connected to the top of the positioning plate 26. The brush surface of the brush seat 11 is slidably connected to the surface of the cylinder body 1.

[0037] A limiting groove 12 is also provided in the middle of the positioning plate 26.

[0038] The general process of using the gas cylinder filling device in this embodiment is as follows:

[0039] Insert the cylinder body 1 into the limiting groove 12 of the positioning plate 26. Before inflation, connect the air pump direct connection pipe 23 to the air delivery pipe of the external air pump. After adding coolant into the storage tank 27, start the stepper motor 31. The movable bracket 22 can drive the air pump direct connection pipe 23 to move up and down under the screw transmission effect of the threaded rod 32 and connect with the cylinder body 1 at different heights. Then, use the quick connector 13 to lock it to prevent air leakage. At the same time as inflation, start the water pump 6. The coolant flows from the connecting pipe 7 into the support frame 24 and is sprayed out from the nozzle 25. At the same time, start the reduction motor 9, so that the positioning plate 26 drives the brush seat 11 to rotate, thereby mixing the coolant on the surface of the cylinder body 1, completing the overall cooling of the cylinder body 1, and improving the safety factor during inflation.

[0040] The beneficial technical effects of the gas cylinder filling device in this application are roughly as follows:

[0041] Insert the cylinder body 1 into the limiting groove 12 of the positioning plate 26. Before inflation, connect the air pump direct connection pipe 23 to the air supply pipe of the external air pump. During operation, the stepper motor 31 on the top of the workbench 21 can be automatically started. Its motor shaft drives the threaded rod 32 to rotate. Two sets of linear shafts 33 pass through the movable bracket 22 and limit its position. With the threaded surface of the threaded rod 32 cooperating with the lead screw in the built-in threaded groove 4, the movable bracket 22 can move smoothly in the vertical direction along the opening surface of the through hole 5. According to the specific height of the cylinder body 1, the air pump direct connection pipe 23 is connected to the air inlet on the top of the cylinder and fastened with quick connector 13 to prevent air leakage, thus improving the applicability of the device. In order to avoid the cylinder body from overheating due to high-pressure gas entering the cylinder body 1, the device can pre-cool the cylinder body. The liquid is poured into the storage tank 27. During the inflation process, the water pumps 6 on both sides are started simultaneously. The liquid inside the storage tank 27 is sucked in through the suction pipe 8 and discharged into the support frame 24 through the connecting pipes 7 on both sides. It flows through the nozzles 25 on both sides and is sprayed out from the nozzle ends, so that the coolant is sprayed on the top of the cylinder body 1. At the same time, the reduction motor 9 at the lower end of the positioning plate 26 is started. Its motor shaft drives the positioning plate 26 and the outer ring-shaped brush seat 11 to rotate, thereby distributing the surface liquid evenly and completing the overall cooling of the cylinder body 1. On the other hand, the excess coolant remains in the water storage sleeve 10 under the action of gravity. The bottom electromagnetic discharge valve 14 is started through the control terminal, so that the coolant inside the water storage sleeve 10 is sucked back into the storage tank 27 for recycling.

[0042] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this application should be included within the protection scope of this application.
