Description

Technical Field

[0001] This utility model relates to a liquefied gas filling device, and more particularly to a high-quality filling device for a liquefied gas mixture. Background Technology

[0002] Liquefied gas mixtures, due to their specific component ratios, are widely used in chemical synthesis, energy supply, medical emergency care, and food processing. Their filling process requires specialized equipment to mix multiple liquefied gases in a preset ratio before injecting them into filling bottles. This is a crucial step in ensuring the performance and safety of the mixtures in subsequent use.

[0003] In existing liquefied gas mixture filling equipment, the filling head needs to be directly connected to the bottle neck interface during the filling process. Then, the pump body is started, and the liquefied gas mixture is pressurized and delivered into the filling bottle through the conveying channel formed by the pipe body to complete the filling operation. During the process of the pump body driving the mixture to convey along the pipe body, the pressure fluctuation of the fluid in the pipe body will continuously impact the filling bottle, causing the bottle body to easily shake during the filling process. This shaking will directly act on the docking part between the filling head and the bottle body, destroying the original sealing fit between the two, thus creating gaps, and in severe cases, even filling leakage. Utility Model Content

[0004] The purpose of this invention is to provide a high-quality filling device for liquefied gas mixtures. This invention is characterized by its ability to prevent gaps from forming at the connection points due to shaking, thus fundamentally solving the problem of liquefied gas mixture leakage.

[0005] The technical solution of this utility model is a high-quality filling device for liquefied gas mixtures, including a filling machine;

[0006] The leak-proof component includes a filling bottle, a tube, a support block, a rotating rod, a top plate, a clamping frame, and a base plate. The tube is located at the bottom of the filling machine, the base plate is fixed to the bottom of the tube, the filling bottle is located at the lower part of the filling machine, the top plate is fixed to the top of the filling bottle, the support block is fixed to the outer wall of the top plate, the rotating rod is located between the two support blocks, and the bottom of the clamping frame is rotatably connected to the outer surface of the rotating rod, and the inner surface of the clamping frame clamps and wraps around the outer surfaces of the top plate and the base plate.

[0007] Furthermore, a pressure plate is fitted onto the outer surface of the tube body, and an inner groove is formed on the top of the clamping frame, with the pressure plate embedded inside the inner groove.

[0008] Furthermore, a guide groove is provided on the outer surface of the tube body, and a guide block is provided on the inner wall of the pressure plate. The guide block is slidably connected inside the guide groove, and a vertical rod is fixed inside the guide groove. The vertical rod passes through the middle of the guide block.

[0009] Furthermore, a retaining ring is threaded onto the outer surface of the upright, and the retaining ring is tightly fitted to the top of the guide block.

[0010] Furthermore, a pump body is fixed at the bottom of the filling machine, the pipe body is located at the bottom of the pump body, and a hole is opened in the middle of the top plate, with a filling head embedded inside the hole.

[0011] Furthermore, it also includes a support component, which includes a base plate and an inner groove. The base plate is fixed to the bottom of the filling machine, and the inner groove has an opening inside the base plate.

[0012] Furthermore, a rubber ring is bonded to the inner wall of the inner groove, and the rubber ring is clamped to the lower part of the outer surface of the filling bottle.

Detailed Implementation

[0020] The present invention will be further described below with reference to the accompanying drawings and embodiments, but this should not be construed as limiting the present invention.

[0021] Example. A high-quality filling device for liquefied gas mixtures, configured as follows: Figure 1-5 As shown, it includes: a filling machine 11; the filling machine 11 can be a model WQ-50 / 0.1, which uses the Venturi effect to achieve gas ejection mixing. It has a simple structure, low operating cost, and is suitable for small and medium scale, medium and low pressure mixed gas filling.

[0022] The leak-proof component includes a filling bottle 21, a tube 22, a support block 23, a rotating rod 24, a top plate 25, a clamping frame 26, and a base plate 27. The tube 22 is located at the bottom of the filling machine 11, and the base plate 27 is fixed to the bottom of the tube 22. The filling bottle 21 is located at the lower part of the filling machine 11, the top plate 25 is fixed to the top of the filling bottle 21, the support block 23 is fixed to the outer wall of the top plate 25, the rotating rod 24 is located between the two support blocks 23, and the bottom of the clamping frame 26 is rotatably connected to the outer surface of the rotating rod 24, and the inner surface of the clamping frame 26 clamps and wraps around the outer surfaces of the top plate 25 and the base plate 27.

[0023] The initial positioning of the filling head 39 with the inlaid hole 31 and the top plate 25 fitting with the bottom plate 27, combined with the lateral fixation of the top plate 25 and the bottom plate 27 by the clamping frame 26, and the longitudinal pressure of the pressure plate 37 with the inlaid inner groove 32 and the threaded fastening of the fixing ring 36, forms a multi-dimensional sealing and fixing structure. This structure can completely limit the shaking of the filling bottle 21 during the filling process, avoid gaps at the docking part due to shaking, and solve the problem of leakage of liquefied gas mixture from the root, which not only reduces the waste of gas resources, but also avoids the risk of safety accidents.

[0024] A pressure plate 37 is fitted on the outer surface of the tube body 22, and an inner groove 32 is opened on the top of the clamping frame 26, and the pressure plate 37 is embedded in the inner groove 32;

[0025] The positioning effect of the groove ensures that the pressure of the pressure plate 37 on the top plate 25 can be evenly transmitted to the initial sealing surface.

[0026] The outer surface of the tube body 22 is provided with a guide groove 35, and the inner wall of the pressure plate 37 is provided with a guide block 38. The guide block 38 is slidably connected to the inside of the guide groove 35. A vertical rod 34 is fixed inside the guide groove 35, and the middle part of the guide block 38 passes through the vertical rod 34.

[0027] The guide block 38 slides inside the guide groove 35, providing lateral restraint for the movement of the guide block 38.

[0028] A retaining ring 36 is threaded onto the outer surface of the upright 34, and the retaining ring 36 is tightly fitted to the top of the guide block 38;

[0029] It provides precise guidance for the movement of the pressure plate 37, ensuring that the pressure plate 37 can be stably and accurately embedded in the inner groove 32, and avoiding sealing failure caused by misalignment of the pressure plate 37.

[0030] A pump body 33 is fixed at the bottom of the filling machine 11, and the tube body 22 is set at the bottom of the pump body 33. A hole 31 is opened in the middle of the top plate 25, and a filling head 39 is embedded inside the hole 31.

[0031] The filling head 39 can be embedded inside the bore 31, so that the top plate 25 and the bottom plate 27 fit tightly together. The planar contact of the two plates forms an initial sealing surface, laying the foundation for subsequent leakage prevention.

[0032] Working principle:

[0033] Before starting the filling operation, first insert the filling head 39 at the bottom of the filling machine 11 into the corresponding hole 31, so that the top plate 25 and the bottom plate 27 fit tightly together. Then, rotate the bottom of the clamping frame 26 around the rotating rod 24, so that the clamping frame 26 can rotate toward the fitting point of the top plate 25 and the bottom plate 27, until the clamping frame 26 is completely wrapped around the outside of the two plates. Then, push the guide block 38 to move axially along the upright 34. The sliding fit between the outer surface of the guide block 38 and the guide groove 35 ensures that the guide block 38 only moves axially along the upright 34. Finally, the pressure plate 37 is embedded in the inner groove 32. Through the positioning effect of the groove, the pressure of the pressure plate 37 on the top plate 25 can be evenly transmitted to the initial sealing surface. The threaded engagement between the inner wall of the fixing ring 36 and the outer wall of the upright 34 converts the rotational motion into axial movement, causing the fixing ring 36 to move closer to the pressure plate 37 and squeeze the pressure plate 37. Finally, the pump body 33 is started, and the gas inside the filling machine 11 is transmitted to the filling head 39 through the pipe body 22, and then transmitted to the inside of the filling bottle 21 by the filling head 39.

[0034] Please see Figure 1-5 As shown, this embodiment, based on the above embodiment, further includes:

[0035] The support component includes a base plate 41 and an inner groove 42. The base plate 41 is fixed to the bottom of the filling machine 11, and the inner groove 42 is formed inside the base plate 41.

[0036] The rigid structure of the inner groove 42 provides initial constraints on the filling bottle 21 from four directions: up, down, left, and right. This restricts the large displacement of the filling bottle 21 in the horizontal and vertical directions, laying a rigid support foundation for subsequent precise positioning and anti-swaying, and preventing the filling bottle 21 from shifting arbitrarily due to the lack of initial constraints.

[0037] A rubber ring 43 is bonded to the inner wall of the inner groove 42, and the rubber ring 43 is clamped to the lower part of the outer surface of the filling bottle 21.

[0038] Based on the deformation and recovery characteristics of elastic materials, the deformed rubber ring 43 will generate a reverse radial elastic force, which acts uniformly on the circumference of the outer wall of the filling bottle 21 to form a surrounding flexible clamping force.

[0039] Working principle:

[0040] Before filling, the filling bottle 21 is inserted into the inner groove 42 along the opening direction of the inner groove 42. When the filling bottle 21 is fully inserted into the inner groove 42, the pre-set annular rubber ring 43 on the inner wall of the inner groove 42 will make extrusion contact with the outer wall of the filling bottle 21. The insertion action of the filling bottle 21 will apply radial pressure to the rubber ring 43, causing the rubber ring 43 to undergo elastic deformation and be clamped to the outside of the filling bottle 21.
