Description

Technical Field

[0001] This utility model relates to the technical field of gas cylinder cleaning equipment, specifically a gas cylinder internal cleaning device. Background Technology

[0002] Gas cylinders, as common pressure vessels, are widely used in industrial gases, medical gases, fire-fighting gases, and other fields. Because the inside of gas cylinders is in constant contact with various gases, impurities such as moisture, oil, and particulate matter can easily accumulate. If not cleaned promptly, this can not only affect the purity of the gas but also corrode the cylinder walls, reduce the cylinder's lifespan, and even lead to safety accidents.

[0003] Currently, cleaning the inside of gas cylinders is mostly done manually. Operators use long-handled brushes to reach inside the cylinders and scrub, which is inefficient, makes it difficult to guarantee cleaning quality, and poses certain safety hazards. Some semi-automatic cleaning equipment exists, but its complex structure and limited applicability prevent it from effectively and comprehensively cleaning the inside of gas cylinders.

[0004] Therefore, there is a need for an internal cleaning device with a reasonable structure, simple operation, and good cleaning effect to efficiently clean the inside of gas cylinders of a certain size. Utility Model Content

[0005] The purpose of this invention is to provide a gas cylinder internal cleaning device to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A gas cylinder internal cleaning device includes a support platform forming a hollow cavity. The device is characterized by having two rotating roller devices arranged linearly along the length of the support platform on its surface. The top of each rotating roller device has a semi-circular notch, within which several rotating rollers are uniformly arranged along their own semi-circular arc surface. The roller closest to the support platform surface is driven by a rotary motor. A support plate is formed on the right side of the support platform surface, and a brush rod is slidably connected through the middle of the support plate. One end of the brush rod near the rotating roller device has bristles. The other end of the brush rod is connected to a moving drive assembly and is driven to slide by the moving drive assembly. The gas cylinder to be cleaned is placed flat between the two rotating roller devices. The rotary motor is started to drive the gas cylinder to rotate. Simultaneously, the moving drive assembly drives the brush rod to pass through the gas cylinder opening and slide back and forth inside the gas cylinder for cleaning.

[0008] Furthermore, the moving drive assembly includes a lead screw motor mounted on the bottom wall of the hollow cavity. The free end of the lead screw of the lead screw motor is rotatably connected to the left side wall of the hollow cavity, and the lead screw of the lead screw motor is threadedly connected to a nut block. One end of a slide rod is fixedly connected to the top surface of the nut block, and the other end of the slide rod slidably passes through the right side wall of the hollow cavity and is fixedly connected to the end of the brush rod away from the bristles via a connecting rod.

[0009] Furthermore, the bristles are flexible bristles.

[0010] Furthermore, a positioning component is installed on the right side of the support platform to position and limit the placement of the gas cylinder.

[0011] Furthermore, the positioning component includes a column fixedly mounted on the right side of the support platform and a limiting head fixed to the top of the column.

[0012] Furthermore, the left-side rotating roller device is equipped with pressing devices that can slide up and down on both sides to hold the gas cylinder in place and prevent it from jumping when it is rotated.

[0013] Furthermore, the pressing device includes sliding hole bodies symmetrically arranged on both sides of the left-side bearing roller device, and vertical sliding rods slidably connected to the sliding hole bodies. The tops of the vertical sliding rods on both sides are connected to an arc-shaped pressure top. Several evenly distributed pressure rollers are rotatably embedded in the bottom arc surface of the arc-shaped pressure top. A locking knob is threadedly connected to the side of the sliding hole body through a threaded through hole. By tightening the locking knob, the vertical sliding rod can be pressed against to achieve locking.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] 1. This utility model, by setting up two rotating roller devices, with rotating rollers evenly arranged within the semi-circular notch at the top and driven by a rotary motor, can achieve stable rotation of the gas cylinder, avoiding the unevenness and high labor intensity problems of manual rotation. Furthermore, a moving drive component drives the brush rod to reciprocate inside the gas cylinder, achieving comprehensive cleaning of the inner wall, resulting in high cleaning efficiency and excellent cleaning effect. The brush bristles are made of a flexible material, which can effectively remove dirt without damaging the inner wall of the cylinder.

[0016] 2. By setting up positioning components and pressing devices, this utility model can effectively fix the gas cylinder and prevent it from shifting or jumping during the rotation process, thereby further improving the stability and safety of the cleaning process. Attached Figure Description

Detailed Implementation

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] like Figures 1 to 6 As shown, the present invention provides a gas cylinder internal cleaning device, including a support platform 1, the support platform 1 having a hollow cavity 11 inside, and two rotating roller devices 2 arranged linearly along its length on the platform surface. Further optimized, the top of the rotating roller device 2 has a semi-circular notch 21, and several rotating rollers 22 are evenly rotatably arranged along the arc surface of the semi-circular notch 21, wherein the rotating roller 22 closest to the platform surface is driven to a rotary motor 23. Preferably, as shown... Figure 3 As shown, a gearbox 24 connects the rotary motor 23 and the rotating roller 22. Specifically, when the gas cylinder 100 is placed flat on the two rotating roller devices 2, the rotating roller 22 can drive the gas cylinder to rotate smoothly, avoiding slippage or deviation.

[0026] Furthermore, a support plate 4 is fixedly installed on the right side of the support platform 1. A brush rod 5 is slidably connected through the middle of the support plate 4. One end of the brush rod 5 is provided with bristles 51, and the other end is connected to the moving drive assembly 3. Specifically, the moving drive assembly 3 includes a lead screw motor 31 installed on the bottom wall of the hollow cavity 11. The free end of the lead screw of the lead screw motor 31 is rotatably connected to the left side wall of the hollow cavity 11, and a nut block 32 is threaded onto the lead screw. One end of a sliding rod 33 is fixedly connected to the top surface of the nut block 32, and the other end of the sliding rod 33 slides through the right side wall of the hollow cavity 11 and is fixedly connected to the end of the brush rod 5 away from the bristles 51 through a connecting rod 34. By rotating the lead screw motor 31 forward and backward, the brush rod 5 can be driven to reciprocate directly within the gas cylinder 100. In conjunction with the rotation of the gas cylinder, the inner wall of the gas cylinder is thoroughly cleaned.

[0027] Furthermore, the brush bristles 51 are preferably made of soft bristles, such as those made of pig bristles, which can effectively remove dirt without scratching the inner wall of the gas cylinder, thus extending the service life of the gas cylinder.

[0028] To further improve the adaptability and stability of the device, a positioning component 6 is also installed on the right side of the support platform 1. Specifically, the positioning component 6 includes a column 61 fixed to the right side of the platform and a limiting head 62 located on the top of the column 61, which is used to axially limit the gas cylinder 100 placed in the platform to prevent it from moving during the cleaning process.

[0029] Furthermore, the left-side receiving roller device 2 is equipped with pressing devices 7 that can slide up and down on both sides to press and hold the gas cylinder 100 to prevent it from jumping. Specifically, such as... Figure 3 , Figure 4 and Figure 5 As shown, the pressing device 7 includes sliding hole bodies 71 symmetrically arranged on both sides of the receiving roller device 2, and vertical sliding rods 72 slidably connected to the sliding hole bodies 71. The tops of the vertical sliding rods 72 on both sides are connected to an arc-shaped pressure top 73. Several evenly distributed pressure rollers 74 are rotatably embedded in the bottom arc surface of the arc-shaped pressure top 73. In addition, the side of the sliding hole body 71 is also provided with a threaded through hole, and a locking rod knob 75 is threadedly connected to it. By tightening the locking rod knob 75, the vertical sliding rod 72 can be pressed against to fix the pressing height, which can adapt to gas cylinders of different diameters.

[0030] The specific cleaning operation method when using this device is as follows:

[0031] The operator first places the gas cylinder 100 to be cleaned flat on the two receiving roller devices 2 and performs initial positioning using the positioning component 6. Then, the height of the holding device 7 is adjusted so that the arc-shaped pressure top 73 presses down on the top of the gas cylinder 100, and the position is locked using the locking lever knob 75.

[0032] Next, a cleaning medium is added manually into the compressed gas cylinder through the cylinder opening, and the rotary motor 23 is started, causing the gas cylinder 100 to start rotating. At the same time, the lead screw motor 31 in the moving drive assembly 3 is started, and the brush bristles 51 are driven to be pushed in from the cylinder opening. Subsequently, the lead screw motor 31 is controlled by the program to drive the brush rod 5 to perform reciprocating linear motion within a certain range (determined by the length of the gas cylinder 100), and the brush bristles 51 penetrate deep into the gas cylinder for thorough cleaning.

[0033] Next, after cleaning is completed, stop the motor, release the pressure device, remove the gas cylinder, and then manually invert the gas cylinder to pour out the cleaning medium.

[0034] Finally, after the cleaning medium has been poured out, a second cleaning can be performed until the inner wall of the gas cylinder is thoroughly cleaned. Then, the cylinder is transported to the drying area and placed upside down to dry.

[0035] This utility model has a reasonable structure, is easy to operate, has high cleaning efficiency, and is widely applicable. It is especially suitable for internal cleaning operations of various types of gas cylinders, such as industrial gas cylinders and medical gas cylinders, and has high practical value and promotion prospects.

[0036] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
