Description

Technical Field

[0001] This application relates to the field of industrial gas filling technology, and in particular to an industrial gas filling manifold. Background Technology

[0002] In the field of industrial gas filling, carbon dioxide is a widely used industrial gas. As the core device for centralized gas supply, the carbon dioxide filling manifold is responsible for distributing carbon dioxide gas to multiple steel cylinder containers.

[0003] Currently, some existing carbon dioxide filling manifolds are installed in a fixed manner, which is not adaptable to cylinders of different heights. Specifically, because the filling nozzle height of the manifold is fixed, when filling cylinders with significantly different heights (such as standard 4L, 5L, 8L, and 40L cylinders), operators have to manually adjust the cylinder position or forcibly bend the filling hose, resulting in low filling efficiency.

[0004] One method of manually adjusting the position of a gas cylinder is to temporarily raise it using a shim block.

[0005] To address the aforementioned issues, an industrial gas filling manifold is now designed. Utility Model Content

[0006] This application provides an industrial gas filling manifold to address the problem that some existing carbon dioxide filling manifolds in the related technology use a fixed installation method, resulting in insufficient adaptability to steel cylinder containers of different heights.

[0007] In a first aspect, an industrial gas filling manifold is provided, comprising:

[0008] The frame has one end tilted upwards, and a fixed gas manifold assembly is provided at the tilted end of the frame.

[0009] Its features are,

[0010] An adjustable gas manifold assembly is provided at the other end of the frame, the adjustable gas manifold assembly including a lifting component mounted on the frame.

[0011] A second gas manifold assembly is connected to the lifting component, and the lifting component is used to drive the second gas manifold assembly to move up and down;

[0012] A gas supply unit is provided on one side of the frame, which is used to supply gas to the fixed gas manifold group and the second gas manifold group.

[0013] In some embodiments, the frame includes opposing side panels with a plurality of reinforcing ribs between the two side panels; one end of the side panel is inclined upward.

[0014] In some embodiments, the fixed gas manifold includes:

[0015] A mounting base is provided at one of the upwardly inclined ends of the two side plates, and the mounting base is U-shaped;

[0019] Valve 1 is installed on the gas injection pipeline.

[0020] In some embodiments, the lifting member includes a slide rail disposed at the bottom of the other end of the side plate. The slide rail is U-shaped, and a slider is slidably disposed inside one side of the slide rail.

[0021] An electric push rod is provided on one side plate, and the bottom end of the piston rod of the electric push rod is connected to the slider.

[0022] In some embodiments, the gas manifold assembly two includes:

[0023] Gas supply pipe two;

[0024] Mounting plates are positioned at both ends of the gas supply pipe;

Detailed Implementation

[0036] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0037] This application provides an industrial gas filling manifold that solves the problem that some existing carbon dioxide filling manifolds in the related technology use a fixed installation method and are not adaptable to steel cylinder containers of different heights.

[0038] Please see Figures 1-3 An industrial gas filling manifold includes: a frame 1, one end of which is inclined upward, and a fixed gas manifold assembly 2 is provided at the inclined end of the frame 1;

[0039] Its features are,

[0040] An adjustable gas manifold assembly 3 is provided at the other end of the frame 1. The adjustable gas manifold assembly 3 includes a lifting component 31 mounted on the frame 1.

[0041] Gas manifold assembly 32 is connected to the lifting component 31, and the lifting component 31 is used to drive the gas manifold assembly 32 to move up and down;

[0042] A gas supply unit 4 is provided on one side of the frame 1. The gas supply unit 4 is used to supply gas to the fixed gas manifold group 2 and the gas manifold group 32.

[0043] The fixed gas manifold assembly 2 is fixed to the upward tilting end of the frame 1, and the height of its gas injection nozzle 24 is preset to be compatible with a standard height 40L steel cylinder (a 40L steel cylinder with a height of 1300mm).

[0044] The adjustable gas manifold assembly 3 is initially located at the other end of the frame 1, and its height is set to accommodate a low-profile 8L steel cylinder (500mm 8L ​​steel cylinder). At this time, the electric push rod 313 in the lifting component 31 is in the extended state, and the slider 312 is located at the bottom of the slide rail 311.

[0045] When filling cylinders of other heights (such as 16L cylinders with a height of 800mm), the lifting component 31 is activated, driving the gas supply pipe 321 to rise synchronously to the appropriate height. After adjustment, the gas supply unit 4 supplies gas synchronously to the fixed gas manifold group 2 and the adjustable gas manifold group 3 through the main pipe 41 and the branch pipe 43, thus completing the filling of two types of cylinders at the same time.

[0046] The height of the gas manifold assembly 32 can be adjusted by the drive unit 31 to accommodate gas cylinders of different heights, thereby improving the flexibility of the equipment. At the same time, the fixed gas manifold assembly 2 and the adjustable gas manifold assembly 3 can work simultaneously to achieve dual-station filling, which greatly improves the filling efficiency.

[0047] like Figure 1 and Figure 2 As shown, in one embodiment, the frame 1 includes oppositely arranged side plates 11, and a plurality of reinforcing ribs 12 are provided between the two side plates 11; one end of the side plate 11 is inclined upward.

[0048] One end of the side plate 11 of the frame 1 is inclined upward, and the top of it is fixed with bolts to the fixed gas manifold assembly 2.

[0049] An adjustable gas manifold assembly 3 is installed at the horizontal end of the side plate 11. The horizontal structure provides a stable vertical guide reference for the lifting component 31, ensuring that the second gas supply pipe 321 only moves along the Z-axis during the lifting process, thus avoiding adjustment jamming caused by side plate deformation.

[0050] The tilting device of the side plate 11 creates a height difference between the fixed gas manifold group 2 and the gas manifold group 32, enabling the filling of two types of steel cylinders in the initial position.

[0051] Multiple reinforcing ribs 12 are arranged along the length of the side plate 11 between the two side plates 11 to form a truss structure, thereby improving the stability of the frame 1.

[0052] It should be noted that side plate 11 is an aluminum alloy side plate, and reinforcing rib 12 is a carbon steel reinforcing rib. While ensuring strength, it can reduce weight compared to a pure steel frame.

[0053] In one embodiment, the fixed gas manifold assembly 2 includes: a mounting base 21 disposed at one of the upwardly inclined ends of the two side plates 11, the mounting base 21 being U-shaped; a gas supply pipe 22 disposed on the mounting base 21; a plurality of gas injection pipes 23 disposed on the gas supply pipe 22; a gas injection nozzle 24 communicating with the gas injection pipes 23; and a valve 25 disposed on the gas injection pipes 23.

[0054] Mounting base 21 has a U-shaped opening, and its two side walls are fastened to the inclined end of side plate 11 by bolts.

[0055] The inclined side plate 11 connects the mounting base 21 to a horizontal plane, matching the taper of the standard steel cylinder body.

[0056] Two to three gas injection pipes 23 are evenly spaced on the gas supply pipe 22. Each pipe corresponds to a gas cylinder injection station. The gas injection pipe 23 adopts a 90° bend structure. Its vertical section is inserted into the side wall hole of the gas supply pipe 22 and sealed by argon arc welding.

[0057] Each gas injection pipe 23 is equipped with a valve 25 (valve 25 is a ball valve, model Q41F-16P), which can be opened and closed 90° by rotating the handle. During filling, the operator can control the valve 25 of a certain station individually to avoid the entire system from shutting down due to the failure of a single gas cylinder.

[0058] like Figure 2 and Figure 4 As shown, in one embodiment, the lifting member 31 includes a slide rail 311 disposed at the bottom of the other end of the side plate 11. The slide rail 311 is U-shaped, and a slider 312 is slidably disposed inside the slide rail 311 on one side. An electric push rod 313 is disposed on the side plate 11 on one side, and the bottom end of the piston rod of the electric push rod 313 is connected to the slider 312.

[0059] The slide rail 311 has a U-shaped cross section and is fastened to the bottom of the horizontal end of the side plate 11 by bolts, which is opposite to the mounting end of the fixed gas manifold assembly 2. The U-shaped opening faces the inside of the frame 1, and a limiting baffle is provided at its bottom to prevent the slider 312 from falling out.

[0060] The slider 312 is a rectangular steel block, and its top is connected to the adjustable gas manifold assembly 3 by bolts. The sides of the slider 312 are embedded in the groove walls of the U-shaped slide rail 311 to form a linear guide.

[0061] The electric actuator 313 is a linear electric actuator (model such as LAF35-500), and its cylinder is fixed to the inner middle of the side plate 11 by a hinge bracket.

[0062] The bottom end of the piston rod is connected to the top of the slider 312 via a fisheye connector.

[0063] The piston rod of the electric push rod 313 retracts, and through the slider 312, it drives the adjustable gas manifold assembly 3 to slide upward along the slide rail 311 until the gas injection nozzle 2 is aligned with the valve port of the gas cylinder.

[0064] As the piston rod extends, the adjustable gas manifold assembly 3 descends rapidly under the influence of gravity.

[0065] When filling cylinders of different heights, the operator inputs the cylinder model through the control panel, and the PLC controller drives the electric push rod 313 to adjust the height of the adjustable gas manifold assembly 3 so that the gas injection nozzle 2 is aligned with the cylinder valve port, with a coaxiality deviation of ≤0.3mm.

[0066] like Figure 3 and Figure 4 As shown, in one embodiment,

[0067] The gas manifold assembly 32 includes:

[0068] Gas supply pipe 2 321;

[0069] Mounting plates 322 are respectively installed at both ends of the second gas supply pipe 321;

[0070] One side of the mounting plate 322 is connected to the other side of the slider 312. The other side of the mounting plate 322 is provided with a rotating shaft 323. A roller 324 is rotatably mounted on the rotating shaft 323. The roller 324 slides in cooperation with the slide rail 311 on the other side.

[0071] Multiple gas injection pipes are also installed on gas supply pipe 2 321. Gas injection pipes 2 are equipped with gas injection nozzles 2 and valves 2 are installed above gas injection pipes 2.

[0072] Two to four gas injection pipes are evenly distributed along the axial direction of gas supply pipe 2 321. Each group of pipes is led out by a stainless steel elbow, extends vertically downwards and connects to gas injection nozzle 2.

[0073] The second gas injection pipe and the second gas supply pipe 321 are interconnected and connected by a full-penetration weld structure.

[0074] The left mounting plate 322 is rigidly connected to the slider 312 by bolts, and the connection surface is coated with thread locking adhesive to prevent vibration from loosening.

[0075] A through hole is provided in the center of the mounting plate 322 on the right side for mounting the rotating shaft 323.

[0076] One end of the rotating shaft 323 is connected to the right mounting plate 322 via a deep groove ball bearing, and the other end is axially positioned via a shaft elastic retaining ring.

[0077] The roller 324 has an embedded deep groove ball bearing, which is clearance-fitted with the shaft 323 to ensure low-friction rotation.

[0078] The outer circle of roller 324 forms a line contact with the groove wall of U-shaped slide 311, allowing roller 324 to slide linearly on the groove wall of slide 311.

[0079] In actual use, when the piston rod of the electric push rod 313 retracts, the left mounting plate 322 slides upward along the U-shaped slide 311 via the slider 312, and the right roller 324 rolls synchronously in the other slide 311, reducing frictional resistance.

[0080] Each gas injection pipe is equipped with valve two above it (valve two is a manual ball valve, model Q41F-16P).

[0081] During filling, the operator first rotates valve two to the fully open position, then monitors the pressure of gas supply unit 4 through the pressure gauge on the cylinder. When the pressure reaches the set value, valve two is closed to achieve quantitative filling.

[0082] like Figure 4 and Figure 5 As shown, in one embodiment, the gas supply unit 4 includes a main pipe 41, a valve 42 is provided on the main pipe 41, two branch pipes 43 are provided on the main pipe 41, one end of the branch pipe 43 extends into the two side plates 11, and a gas supply pipe 44 is connected to the branch pipe 43. The two gas supply pipes 44 are respectively connected to the first gas supply pipe 22 and the second gas supply pipe 321. A valve 45 is provided on the gas supply pipe 44, and a pressure gauge and a pressure transmitter are provided on the main pipe 41.

[0083] A pressure gauge is installed at the upstream end of the main pipeline 41 (near the gas supply source), and a pressure transmitter is installed at the downstream end. The transmitter outputs to the PLC controller to monitor pressure fluctuations in real time.

[0084] Two branch pipes 43 are symmetrically led out from the middle section of the main pipe 41 to reduce local resistance loss. The branch pipes 43 extend into the side plate 11 and then connect with the air supply pipe 44.

[0085] Open valve 3 42 and open valve 45 corresponding to the target station. The gas flows through the main pipeline 41 → branch pipe 43 → gas delivery pipe 44 → gas supply pipe 1 22, and finally fills the gas cylinder through the gas injection nozzle 1 24.

[0086] When the two stations are filled simultaneously, valve 3 42 and two valves 45 are opened to connect the main pipeline 41 with the two gas supply pipes 44. Gas is supplied to gas supply pipe 1 22 and gas supply pipe 2 321 at the same time to achieve simultaneous filling of the two stations.

[0087] It should be noted that in actual use, a mass flow meter is also installed on the gas supply pipe 44. The PLC controller dynamically adjusts the opening of valve 45 according to the flow difference ΔQ (automatic correction when ΔQ>5%) to ensure that the filling rate of the two stations is consistent (error ≤±2%).

[0088] When the pressure transmitter detects that the pressure in the main pipeline 41 is >25MPa (overpressure) or <2MPa (underpressure), the PLC controller immediately closes valve 42 and both valves 45 to cut off the gas supply. This is existing technology and will not be described in detail here.

[0089] like Figure 4 and Figure 5 As shown, it should be noted that the bottom end of the air supply pipe 44 connected to the second air supply pipe 321 is provided with a metal corrugated pipe, which is connected to the second air supply pipe 321.

[0090] In the connection between the gas supply pipe 321 and the gas delivery pipe 44, the function of the metal corrugated pipe is to solve the dynamic displacement problem that is incompatible with rigid pipes.

[0091] Specifically, through the elastic deformation of the corrugated pipe, the flexible metal hose can simultaneously compensate for axial displacement, ensuring stress-free connection of the piping system.

[0092] The metal corrugated pipe is a U-shaped corrugated pipe (wave pitch 12mm, wave height 8mm, number of layers 4), and its flexibility coefficient (K=0.14).
