Abstract
Description
Technical Field
[0001] This application relates to the field of gas cylinder cleaning technology, and more specifically, to a gas cylinder cleaning auxiliary device. Background Technology
[0002] In the field of electronic specialty gases, particularly in the production and handling of electronic specialty gas pressure vessels (hereinafter referred to as "specialty gas cylinders"), the treatment of the container's inner wall is a crucial step in ensuring gas purity and safety. As containers for storing and transporting high-purity, highly reactive, or special-property gases, the cleanliness of the inner wall of specialty gas cylinders directly affects the purity and stability of the gas, as well as the quality of subsequent electronic device production. Therefore, precise grinding, cleaning, and drying of the inner wall of specialty gas cylinders is essential.
[0003] Traditional methods for treating the inner walls of special gas cylinders primarily rely on manual operation, which has several limitations. Firstly, the effectiveness of manual cleaning largely depends on the operator's skill level, work attitude, and sense of responsibility. The instability of these factors makes it difficult to guarantee the consistency and repeatability of the cleaning process. Even the same operator's performance can vary significantly at different times or under different psychological states, thus affecting the cleaning quality.
[0004] Secondly, manual cleaning is inefficient, especially when facing large-scale production demands. Manual operation is not only time-consuming but also labor-intensive, hindering cost control and efficiency improvement. Furthermore, manual operation cannot completely avoid the risk of physical damage or secondary contamination to the inner wall of the gas cylinders, both of which negatively impact gas purity.
[0005] Furthermore, with the rapid development of the electronics industry, the requirements for the cleanliness of the inner walls of special gas cylinders are becoming increasingly stringent. Ordinary manual cleaning methods are no longer sufficient to meet the demands of high-precision and high-efficiency production. Especially in the preparation of some high-end electronic materials, the purity requirements for gases are extremely high; any minute impurities can have a fatal impact on the quality of the final product.
[0006] In view of the above problems, the industry urgently needs an automated, efficient and reliable special gas cylinder inner wall treatment technology that can replace traditional manual cleaning. Utility Model Content
[0007] Based on the above problems, this application proposes a gas cylinder cleaning auxiliary device to solve the technical problem that traditional gas cylinder cleaning relies on manual labor and has poor cleaning effect.
[0008] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows:
[0009] A gas cylinder cleaning auxiliary device includes a bracket, a working platform mounted on the bracket, one end of the working platform being rotatably connected to the bracket, the other end of the working platform abutting against the bracket, a hydraulic cylinder being mounted between the working platform and the bracket, a clamping structure being mounted on the working platform, a rotating structure being mounted on the working platform, and a cleaning pipeline for transmitting cleaning medium being mounted on the other end of the working platform.
[0010] In one specific implementation, two hydraulic cylinders are provided, which are symmetrically arranged on the left and right sides of the bracket. One end of each hydraulic cylinder is hinged to the bracket, and the other end is hinged to the working platform.
[0011] In one specific implementation, the clamping structure is mounted on the bracket via a mounting plate. The rotating structure includes a driven wheel, a support wheel, and a drive motor mounted on the bracket via the mounting plate. The support wheel is rotatably connected to the mounting plate, and the driven wheel is rotatably connected to the mounting plate via a pin. The clamping structure is fixedly connected to the pin. At least one driven wheel and one support wheel are provided. A transmission belt for transmitting the power of the drive motor is provided between each driven wheel, each support wheel, and the power output end of the drive motor.
[0012] In one specific implementation, the drive belt is wound in an S-shaped path between each of the driven pulleys and each of the support pulleys.
[0013] In one specific implementation, the cleaning pipeline is mounted on the bracket via pipe clamps.
[0014] In one specific implementation, the cleaning pipeline is connected to the gas cylinder to be cleaned, and the connection between the cleaning pipeline and the gas cylinder is rotatably connected.
[0015] In one specific implementation, a fixing ring for stabilizing the gas cylinder to be cleaned is installed on the working platform, and the gas cylinder to be cleaned is rotatably connected to the inner wall of the fixing ring.
[0016] In one specific implementation, at least one roller is mounted on the fixing ring, the roller is rotatably connected to the fixing ring, and the roller abuts against the cylinder to be cleaned.
[0017] The positive effects of this utility model are:
[0018] This device, through its automated design, avoids the instability caused by factors such as operator skill level, work mood, and sense of responsibility in manual cleaning. Components such as the clamping structure, rotating structure, and cleaning pipelines all operate according to preset programs and parameters, ensuring the consistency and repeatability of the cleaning process.
[0019] The hydraulic cylinders, rotating structures, and cleaning pipelines in the device work together to achieve rapid and efficient cleaning of the inner walls of special gas cylinders. Compared to manual cleaning, this device significantly improves cleaning efficiency while reducing the labor intensity of operators.
[0020] The clamping and rotating structures designed in this device enable it to stably clamp and rotate the special gas cylinder, avoiding physical damage that may occur due to improper operation during manual cleaning. Simultaneously, the rotating connection design at the junction of the cleaning pipeline and the gas cylinder reduces potential damage to the cylinder's inner wall during the cleaning process. Furthermore, the automated cleaning process minimizes human intervention, thereby reducing the risk of secondary contamination. Attached Figure Description

[0028] Example
[0029] like Figure 1-3 As shown, a gas cylinder cleaning auxiliary device includes a support 1, on which a working platform 2 is mounted. One end of the working platform 2 is rotatably connected to the support 1, and the other end of the working platform 2 abuts against the support 1. Two hydraulic cylinders are installed between the working platform 2 and the support 1, symmetrically arranged on the left and right sides of the support 1. One end of each hydraulic cylinder is hinged to the support 1, and the other end is hinged to the working platform 2. The support 1 stably supports the entire device. The design of the working platform 2 allows gas cylinders to be placed on it for cleaning. The design of one end rotatably connected to the support 1 and the other end abutting against the support 1 allows the working platform 2 to rotate smoothly under the drive of the hydraulic cylinders.
[0030] The working platform 2 is equipped with a clamping structure 8, which uses existing technology and will not be described in more detail here. It is mounted on the bracket 1 via a mounting plate and fixedly connected to a pin shaft, securely clamping the gas cylinder to prevent shaking or detachment during cleaning. The clamping structure 8 is mounted on the bracket 1 via the mounting plate. The working platform 2 is equipped with a rotating structure, and a cleaning pipeline 7 for transmitting the cleaning medium is provided at the other end of the working platform 2. The cleaning pipeline 7 is mounted on the bracket 1 via a pipe clamp 9.
[0031] The rotating structure includes a driven wheel 3, a support wheel 4, and a drive motor 6 mounted on the bracket 1 via a mounting plate. The support wheel 4 is rotatably connected to the mounting plate, and the driven wheel 3 is rotatably connected to the mounting plate via a pin. The clamping structure 8 is fixedly connected to the pin. At least one of the driven wheel 3 and the support wheel 4 is provided. A transmission belt 5 for transmitting power from the drive motor 6 is provided between the power output ends of each driven wheel 3, each support wheel 4, and the drive motor 6. The transmission belt 5 is wound in an S-shaped path between each driven wheel 3 and each support wheel 4. Including components such as the driven wheel 3, support wheel 4, and drive motor 6, the transmission belt 5 wound in an S-shaped path between the wheels achieves smooth power transmission. This design ensures that the gas cylinder rotates evenly during the cleaning process, thereby thoroughly cleaning the inner wall, improving the uniformity and efficiency of cleaning, and ensuring cleaning quality.
[0032] The cleaning pipeline 7 is connected to the gas cylinder to be cleaned, and the connection between the cleaning pipeline 7 and the gas cylinder is rotatably connected. A fixing ring 10 for stabilizing the gas cylinder to be cleaned is installed on the working platform 2. The gas cylinder to be cleaned is rotatably connected to the inner wall of the fixing ring 10, and is mounted on the bracket 1 by a pipe clamp 9, connecting to the gas cylinder to be cleaned, with the connection also rotatably connected. This design ensures smooth transmission of the cleaning medium into the gas cylinder, while preventing damage to the pipeline due to cylinder rotation during the cleaning process.
[0033] A fixing ring 10 is mounted on the working platform 2 to stabilize the steel cylinder to be cleaned. At least one roller 11 is installed on the fixing ring 10, and the roller 11 is rotatably connected to the fixing ring 10. The roller 11 is rotatably connected to the steel cylinder to be cleaned between the steel cylinder and the inner wall of the fixing ring 10. This design can ensure that the steel cylinder rotates stably during the cleaning process.
[0034] Working principle:
[0035] Step 1: Flip the work platform 2 to a horizontal position and manually place the gas cylinder into the clamping mechanism;
[0036] Step 2: According to the set program, control the clamping mechanism to clamp the gas cylinder with force and clamp the gas cylinder;
[0037] Step 3: According to the set program, control the flipping angle of the flipping mechanism to flip the work platform 2 to 90° with the ground of the support 1;
[0038] Step 4: According to the set program, control the parameters such as the type of cleaning medium, pressure, temperature, and time. The cleaning medium is sprayed onto the inner wall of the gas cylinder through the cleaning pipeline 7 for cleaning.
[0039] Step 5: According to the set program, control the rotation direction, speed and other parameters of the rotating mechanism to drive the fixture to rotate together;
[0040] Step 6: After cleaning is completed, the cleaning medium stops spraying and the rotating mechanism stops according to the set program. The flipping mechanism controls the working platform 2 to rotate to 0° with the ground (horizontal position).
