Technical Field

[0001] The present invention relates to the technical field of gas cylinder cleaning, and in particular to a gas cylinder internal cleaning device and a gas cylinder internal cleaning method. Background Art

[0002] In industrial production and daily life, gas cylinders are a common container for storing and transporting gas, and their internal cleanliness is crucial to the quality and safety of the gas. Gas cylinder cleaning equipment is mainly used to remove pollutants and microorganisms inside the gas cylinder to ensure the cleanliness and hygiene of the gas cylinder, thereby ensuring the quality and safety of the gas. If the cleanliness of the gas cylinder does not meet the standard, it may lead to production difficulties, product contamination, and even production line blockage, which will significantly reduce production efficiency and the overall quality of the product.

[0003] Existing gas cylinder cleaning technology mainly relies on manual cleaning or semi-automatic cleaning equipment. Manual cleaning is inefficient, labor-intensive, and the cleaning effect is greatly affected by human factors, making it difficult to ensure the consistency of cleaning quality. Although semi-automatic cleaning equipment has improved the cleaning efficiency to a certain extent, it is still complicated to operate and requires manual assistance to discharge sewage, which affects the cleaning efficiency and effect. Summary of the invention

[0004] In view of the deficiencies in the prior art, an embodiment of the present invention aims to provide a gas cylinder internal cleaning device, aiming to solve the problems of low cleaning efficiency, unstable cleaning quality, incomplete cleaning and inconvenient sewage discharge in the prior art.

[0005] In order to achieve the above objectives, the embodiments of the present invention provide the following technical solutions:

[0006] A gas cylinder internal cleaning device comprises: a base, a mounting assembly and a cleaning assembly; the mounting assembly comprises a support platform and a fixed frame, the support platform is mounted on the base, and one end of the support platform is rotatably connected to the base, and a roller for supporting the gas cylinder is arranged on the bottom surface of the support platform; the fixed frame is located on the rear side of the support platform, and the fixed frame is provided with a clamping mechanism for pressing the gas cylinder; the cleaning assembly comprises a movable plate and a cleaning brush, the movable plate is mounted on the fixed frame and can be raised and lowered relative to the fixed frame, the cleaning brush is rotatably mounted on the movable plate, and the cleaning brush comprises a hollow brush rod, and bristles are arranged on the rod wall of the brush rod.

[0007] An embodiment of the present invention also provides a cleaning method for the gas cylinder internal cleaning device as described above, comprising: placing the gas cylinder to be cleaned on the roller of the support platform, and the gas cylinder is moved to the right end under the drive of the roller, so that the cleaning brush is inserted into the gas cylinder from the bottle mouth of the gas cylinder, and the clamping mechanism on the top of the gas cylinder presses the gas cylinder; the cleaning brush rotates and the end of the brush rod sprays cleaning liquid to clean the inside of the gas cylinder; the support platform is rotated relative to the base so that the bottle mouth of the gas cylinder faces downward, and the sewage in the gas cylinder is controlled out while cleaning, and then the support platform is rotated and laid flat, and the clamping mechanism is lifted, and the gas cylinder is withdrawn to the left under the drive of the roller, and the next gas cylinder is replaced.

[0008] One or more technical solutions provided in the embodiments of the present invention have at least the following technical effects or advantages:

[0009] The support table and rollers make it easier to move the gas cylinders, significantly reducing the need for manpower. The rollers and clamping mechanism are used to fix the gas cylinders, ensuring that they remain stable during the cleaning process, avoiding uneven cleaning or omissions caused by shaking. The cleaning effect is enhanced by the brush and the water spray nozzle. The rotating connection between the support table and the base allows the cleaned gas cylinders to be inverted after cleaning to facilitate the discharge of the internal sewage, which not only simplifies the post-cleaning work, but also helps to more thoroughly remove the dirt on the inner wall of the gas cylinder, thereby improving the quality and efficiency of cleaning. With this innovative cleaning method, users can complete more cleaning tasks in a shorter time, thereby improving production efficiency and economic benefits.

[0019] It should be noted that the following detailed descriptions are illustrative and are intended to provide further explanation of the present invention. Unless otherwise specified, all technical and scientific terms used in the present invention have the same meanings as those commonly understood by those of ordinary skill in the art to which the present invention belongs. In addition, it should also be understood that when the terms "comprise" and / or "include" are used in this specification, it indicates the presence of features, steps, operations, devices, components and / or combinations thereof.

[0020] In order to solve the technical problems mentioned in the background technology, this embodiment proposes a gas cylinder internal cleaning device, which can adapt to gas cylinders of different specifications, realize all-round cleaning, and facilitate sewage discharge, thereby improving the efficiency and quality of gas cylinder cleaning, simplifying the operation process, and reducing labor intensity, thereby improving production efficiency and economic benefits.

[0021] like Figure 1 , Figure 2 , Figure 3 , Figure 4As shown, the internal cleaning device of the gas cylinder includes a base 2, a mounting assembly 1 and a cleaning assembly 3; the mounting assembly 1 includes a support platform 11 and a fixed frame 14, the support platform 11 is installed on the base 2, and one end of the support platform 11 is rotatably connected to the base 2, and a roller 12 for supporting the gas cylinder is arranged on the bottom surface of the support platform 11; the fixed frame 14 is located on the rear side of the support platform 11, and the fixed frame 14 is provided with a clamping mechanism 15 for pressing the gas cylinder; the cleaning assembly 3 includes a movable plate 32 and a cleaning brush 31, the movable plate 32 is installed on the fixed frame 14, and can be raised and lowered relative to the fixed frame 14, the cleaning brush 31 is rotatably installed on the movable plate 32, and the cleaning brush 31 includes a hollow brush rod 311, and bristles 313 are arranged on the rod wall of the brush rod 311.

[0022] The base 2 is the supporting structure of the entire device, on which a support platform 11 is installed. The stability of the base 2 is the basis for ensuring the operation of the device. The support platform 11 and the cleaning component 3 are fixed on it to ensure stability during use. The clamping mechanism 15 clamps the gas cylinder to ensure that the gas cylinder will not move or deviate from the set position during the cleaning process. The cleaning of the inside of the gas cylinder is achieved by a cleaning brush 31 installed on the movable plate 32. The cleaning brush 31 rotates and sprays liquid through a hollow brush rod 311. The brush rod 311 is provided with bristles 313 on the rod wall, which further enhances the cleaning effect. The movable plate 32 can be raised and lowered in the fixed frame 14, and then adapted to gas cylinders of different sizes, and can adapt to gas cylinders of different specifications for efficient cleaning.

[0023] The base 2 adopts a frame structure design, with a crossbeam at the left end and an opening at the right end. The frame structure is a steel frame used to bear vertical and horizontal loads, and has a high load-bearing capacity, so that the gas cylinder can remain stable during the cleaning process. The left end of the support platform 11 is overlapped on the crossbeam at the left end of the frame structure, and the right end of the support platform 11 is connected to the right end of the frame structure by rotation, allowing the support platform 11 to rotate around the base 2. This design allows the support platform 11 to adjust its angle during the cleaning process, which is convenient for cleaning and draining the gas cylinder.

[0024] A plurality of rollers 12 are arranged in parallel along the length direction of the support platform 11, and the plurality of rollers 12 support the gas cylinder together. The outer peripheral surface of each roller 12 is designed to be concave, which helps to fix the posture of the gas cylinder and prevent the gas cylinder from being offset. The parallel arrangement of the plurality of rollers 12 ensures uniform support of the gas cylinder, making the gas cylinder more stable during the cleaning process. The clamping mechanism 15 is driven by a hydraulic cylinder, and a concave arc plate is installed at the bottom of the hydraulic cylinder to press the gas cylinder, which can ensure the fixation and safety of the gas cylinder during the cleaning process, enhance the fixing effect of the gas cylinder, and thus improve the cleaning efficiency and accuracy.

[0025] In this embodiment, two rows of rollers 12 are installed on the support table 11. At the same time, two clamping mechanisms 15 are provided on the fixed frame 14, and each clamping mechanism 15 corresponds to a set of rollers 12, ensuring that the gas cylinder is more firmly fixed during the cleaning process. The cleaning assembly 3 is provided with two cleaning brushes 31, and each clamping mechanism 15 and the cleaning brush 31 are aligned with the corresponding set of rollers 12, ensuring that the cleaning brush 31 can accurately act on the inside of the gas cylinder. The two-group design can more efficiently complete the cleaning task, reduce the cleaning time, and improve the production efficiency. It can also be arranged in multiple rows to complete the cleaning process of multiple gas cylinders at one time. Such a design not only simplifies the operation process but also significantly improves the efficiency of the cleaning work.

[0026] The driving of the rollers 12 can adopt the existing technology. For example, a driving motor 13 is provided on the side of the support table 11. A driving sprocket is provided on the output shaft of the driving motor 13. The two ends of the roller 12 are rotatably installed on the support table 11, and a driven sprocket is provided at the end of the roller 12. The side plate of the support table 11 is a hollow structure, and a chain is provided inside the side plate. The chain is connected to the driving sprocket and the driven sprocket, and the rotation of the roller 12 is driven through the transmission of the chain, thereby driving the gas cylinder to move. The chain system accurately controls the rotation of the roller 12 in this way, ensuring that the gas cylinder can be accurately positioned and smoothly rotated during the cleaning process.

[0027] The installation assembly 1 further includes a driving mechanism 16. The driving mechanism 16 is a hydraulic cylinder. The bottom end of the driving mechanism 16 is hinged to the bottom of the base 2, and the top end of the driving mechanism 16 is hinged to the support table 11. The driving mechanism 16 is used to make the support table 11 rotate relative to the base 2. The selection of the hydraulic cylinder as the driving mechanism 16 enables the device to provide a powerful power output, enabling the gas cylinder to maintain a stable posture during the cleaning process and simultaneously completing operations such as discharging the cleaning liquid. By adjusting the rotation angle of the support table 11, the cleaning liquid can be smoothly discharged from the inside of the gas cylinder, avoiding the retention of the cleaning liquid in the gas cylinder and ensuring that the cleaned gas cylinder is clean and ready for the next use.

[0028] The body of the fixed frame 14 is a C-shaped structure. The left end of the fixed frame 14 is open, the right end has a back plate 142, and the top has a top beam 141. The cleaning brush 31 is installed on the side of the back plate 142, and the clamping mechanism 15 is installed on the lower side of the top beam 141. The open left end can conveniently place the gas cylinder. The back plate 142 at the right end can provide support for the cleaning brush 31 and ensure the coordinated work between the clamping mechanism 15 and the cleaning brush 31. The clamping mechanism 15 is installed on the lower side of the top beam 141. A reasonable installation position can prevent it from interfering with the work of the cleaning brush 31 when clamping the gas cylinder. Through the C-shaped frame, reasonable position arrangement, and the cooperation of the cleaning brush 31 and the clamping mechanism 15, the efficiency and stability of the device for cleaning the inside of the gas cylinder are ensured.

[0029] Such as Figure 5 As shown, a vertical slot is provided in the back plate 142, a screw rod 35 is installed in the vertical slot, and the movable plate 32 is installed on the screw rod 35 through the movable rod 33. The screw rod 35 and the movable rod 33 are threadedly connected so that the movable plate 32 can move up and down along the vertical slot. Through this threaded connection, the lifting and lowering of the movable plate 32 can be accurately controlled, so that the cleaning brush 31 can be properly lifted and lowered according to the specifications of the gas cylinder.

[0030] like Figure 2 , Figure 6 As shown, a hollow shaft motor 34 is installed on the moving plate 32, and the cleaning brush 31 is rotated by the hollow shaft motor 34. The design of the hollow shaft motor 34 not only provides power for the cleaning brush 31, but also can transmit the cleaning liquid through the hollow shaft, so that the cleaning liquid is sprayed out through the water inlet channel 312 at the left end of the cleaning brush 31 through the water spray port 314. The setting of the water spray port 314 ensures that the cleaning liquid can be directly sprayed to each part inside the gas cylinder during the cleaning process, achieving a good cleaning effect. A drain port 143 is provided on the back plate 142, and the drain port 143 can discharge the cleaning liquid in the gas cylinder after the cleaning is completed. This design can ensure that the gas cylinder discharges waste liquid in time during the cleaning process, avoids the cleaning liquid from being retained inside the gas cylinder, and ensures that the inside of the gas cylinder is completely clean. Through the combination of the hollow shaft motor 34 and the water spray port 314, the cleaning liquid can be sprayed evenly and efficiently, and combined with the drain port 143 on the back plate 142, the overall efficiency and cleaning effect of the cleaning process are further improved.

[0031] The cleaning device is compact, easy to operate, has multiple functions, and is equipped with a convenient roller 12 system, which makes the gas cylinder easier to transport and significantly reduces the manpower requirements. It not only reduces the labor intensity of the operators, but also improves the overall work efficiency.

[0032] At the same time, the cleaning device can clean multiple gas cylinders at one time, which not only saves valuable time and resources, but also makes the cleaning process more consistent, reducing interruptions and delays caused by frequent replacement of gas cylinders. And it can adapt to gas cylinders of different specifications and perform efficient cleaning, which makes the equipment perform well in a variety of application scenarios. Whether it is a large industrial gas cylinder or a small household gas cylinder, it can provide the same efficient and thorough cleaning effect.

[0033] This embodiment also provides a cleaning method for the above cleaning device:

[0034] The gas cylinder to be cleaned is placed on the roller 12 of the support platform 11, and the gas cylinder moves to the right end through the drive of the roller 12. During this process, the cleaning brush 31 is inserted into the gas cylinder from the bottle mouth of the gas cylinder. The support platform 11 and the clamping mechanism 15 ensure that the gas cylinder is firmly maintained in the cleaning position to avoid deviation during the cleaning process.

[0035] The cleaning brush 31 starts to rotate, and sprays cleaning liquid through the end of the brush rod 311, and the liquid cleans the inside of the gas cylinder comprehensively. The cooperation of the bristles 313 and the cleaning liquid can effectively remove dirt and impurities on the inner wall of the gas cylinder.

[0036] Then the support platform 11 rotates so that the mouth of the gas cylinder faces downward, so that the sewage inside the gas cylinder is discharged. After the sewage is discharged, the cleaning liquid can be sprayed again, and the cleaning liquid is discharged while cleaning to improve the cleaning effect. Subsequently, the support platform 11 rotates and lays flat, and the clamping mechanism 15 is lifted, and the roller 12 drives the gas cylinder to withdraw to the left, ready for the next cleaning.

[0037] Specifically, a control panel 21 is installed on one side of the base 2, and the movement of the moving rod 33 on the screw rod 35 is controlled by the control panel 21. The moving rod 33 is fixedly connected to the moving plate 32, and the cleaning brush 31 is aligned with the mouth of the gas cylinder to facilitate the insertion of the cleaning brush 31. The roller 12 on the support platform 11 is driven by the driving motor 13 to rotate, and the gas cylinder is sent to the inside of the device. The clamping mechanism 15 is extended and retracted to enable the clamping claws to clamp the gas cylinder and fix the gas cylinder to avoid uneven cleaning or omissions caused by shaking, thereby achieving a stabilizing effect. The hollow shaft motor 34 starts working to drive the brush rod 311 to rotate, and the brush rod 311 drives the brush to rotate. At this time, the brush starts to rotate. A water spray port 314 is provided on the top of the cleaning brush 31, and a water inlet channel 312 is provided inside the cleaning brush 31. The water flow sprayed from the water spray port 314 helps to effectively remove the dirt on the inner wall, thereby greatly improving the convenience of cleaning. When the inside of the gas cylinder is cleaned to a certain extent, the driving mechanism 16 works to lift the support platform 11, and the sewage in the gas cylinder is discharged through the drain port 143 on the support platform 11, so that more cleaning tasks can be completed in a shorter time, thereby improving production efficiency and economic benefits.

[0038] Although the above describes the specific implementation mode of the present invention in conjunction with the accompanying drawings, it is not intended to limit the scope of protection of the present invention. Those skilled in the art should understand that various modifications or variations that can be made by those skilled in the art on the basis of the technical solution of the present invention without creative work are still within the scope of protection of the present invention.
