Description

Technical Field

[0001] This application belongs to the field of hose cleaning technology, specifically relating to a hose inner surface cleaning device. Background Technology

[0002] The oxygen hoses in the oxygen supply system are relatively long and made of soft material, so the cleaning process mainly involves manually cleaning the inner surface of the hoses. Specifically, a cloth soaked in detergent solution is inserted into the hose from one end and pulled out from the other in a fixed direction, creating friction between the cloth and the inner wall of the hose. During the cleaning process, the cloth is replaced with a clean one as needed, until cleaning is complete. After cleaning, high-purity nitrogen is used for purging, and particle size analysis at the outlet shows no particles larger than 5μm, indicating that the cleanliness of the inner surface of the hose has passed the cleanliness test.

[0003] However, manual scrubbing is inefficient and the cleaning quality is unstable, resulting in a low pass rate for the cleanliness test of the hoses after cleaning. Utility Model Content

[0024] It should be noted that, unless otherwise specified, the embodiments and features described in the present disclosure can be combined with each other.

[0025] Combination Figures 1 to 8 As shown, this embodiment of the present disclosure provides a hose inner surface cleaning device 1, including a fixed frame 300, a flipping frame 100, a drive assembly 200, and a cleaning component. The fixed frame 300 is provided with a cleaning tank 301 for holding cleaning fluid. The flipping frame 100 is movably disposed on the fixed frame 300 and includes a tray 101 for placing the hose. The flipping frame 100 flips relative to the fixed frame 300, allowing the position of the tray 101 to switch between inside and outside the cleaning tank 301. The drive assembly 200 is disposed on the flipping frame 100 and includes a rope 201. The cleaning component is disposed on the tray 101 and connected to one end of the rope 201. The cleaning component can extend into the hose. When the tray 101 is inside the cleaning tank 301, the hose is immersed in the cleaning fluid, and the drive assembly 200 drives the cleaning component to move inside the hose to clean its inner surface.

[0026] The fixing frame 300 provides overall support for the tilting frame 100, the drive assembly 200, and the cleaning components. Both the fixing frame 300 and the tilting frame 100 can be formed by bending and welding stainless steel. A panel 302 can be installed on the area of ​​the fixing frame 300 adjacent to the cleaning tank 301 to prevent cleaning fluid from splashing out during the cleaning of the hose. The fixing frame 300 is provided with a reinforcing plate 303, located on the side where the fixing frame 300 connects to the tilting frame 100, for reinforcement and improved overall stability.

[0027] The fixing frame 300 is provided with a cleaning tank 301, which is used to hold cleaning fluid. When the hose is located in the cleaning tank 301, the cleaning fluid fills the inner cavity of the hose, thereby improving cleaning efficiency. In this embodiment, the cleaning fluid can be a neutral detergent suitable for cleaning hoses or ultrapure water.

[0028] For example, during hose cleaning, a neutral detergent is placed in the cleaning tank 301, and the inner surface of the hose is cleaned by a cleaning component to improve the cleaning effect. After a preset cleaning time, the neutral detergent is drained through the drain pipe of the cleaning tank 301, and ultrapure water is added to the cleaning tank 301. The inner surface of the hose is then cleaned by a cleaning component to remove any remaining neutral detergent and particulate matter. In practical applications, the ultrapure water can be replaced multiple times to improve the cleaning effect. After the final ultrapure water cleaning, a sample is taken from the ultrapure water, and a particle counter is used to detect the size and number of solid particles in the sample for cleanliness testing. Compared to the high-purity nitrogen purging detection method in related technologies, this example reduces the difficulty of detection and improves reliability through sampling detection. The model of the particle counter is not limited. For example, an LJ150C particle counter can be used to test the cleanliness of samples. This particle counter has a detection range of 2μm to 100μm, a sampling speed of ≥20ml / min, a sampling accuracy of better than ±3%, an online operating pressure of 0 to 200kPa, and can be used with water and alcohol as the detection media, and has ≥6 measurement channels. Sampling in this ultrapure water can also be used for the detection of insoluble particles, particulate contamination from chemical reagents and cleaning agents, etc.

[0029] The flipping frame 100 is movably mounted on the fixed frame 300, meaning it can flip relative to the fixed frame 300. The flipping frame 100 includes a tray 101 for holding the tubing. Flipping the flipping frame 100 relative to the fixed frame 300 allows the tray 101 to switch between its position inside and outside the cleaning tank 301. Specifically, flipping the flipping frame 100 relative to the fixed frame 300 moves the tray 101, positioning it outside the cleaning tank 301. This facilitates fixing the tubing to be cleaned onto the tray 101, or removing the cleaned tubing from the tray 101. Flipping the flipping frame 100 relative to the fixed frame 300 moves the tray 101, positioning it inside the cleaning tank 301. In this position, the tubing is completely immersed in the cleaning solution, which fills the tubing's inner cavity during the cleaning process.

[0030] A drive assembly 200 is mounted on a tilting frame 100. The drive assembly 200 includes a rope 201, which can be a steel wire rope. A cleaning component is mounted on a tray 101; that is, the cleaning component is positioned on the tray 101 during operation, specifically inside the hose. One end of the cleaning component is connected to the rope 201, meaning the drive assembly 200 can move the cleaning component by pulling it along the rope 201. The cleaning component can extend into the hose; that is, it can be wholly or partially located inside the hose. The cleaning component can be a brush or a cloth. When the cleaning component is a brush, its outer diameter can be larger than the inner diameter of the hose to ensure sufficient contact between the brush bristles and the inner surface of the hose, improving cleaning efficiency and quality. When the tray 101 is positioned inside the cleaning tank 301, the hose is immersed in the cleaning solution, which fills the inner cavity of the hose. The cleaning component is located inside the hose and is driven by the drive assembly 200 to move back and forth inside the hose to clean the inner surface of the hose, thereby achieving fast and efficient cleaning, improving cleaning quality, and thus increasing the pass rate of hose cleanliness testing after cleaning.

[0031] The hose inner surface cleaning device 1 in this embodiment cleans oxygen hoses used in oxygen supply systems. This embodiment can clean hoses of different specifications. The hose specifications, for example, the inner diameter (in mm) × wall thickness (in mm), can be 3×0.5, 5×0.5, 6×3, 7.5×1.5, 10×2, 11×2.5, or 3.5×1.2. The hose length can be less than or equal to 2m. In practical applications, the size of the cleaning component can be adjusted to accommodate the cleaning of the inner surfaces of hoses of different specifications.

[0032] In some embodiments, combined with Figure 5 , Figure 6 and Figure 8 As shown, the tilting frame 100 also includes a first crossbeam 102, on which a connecting hole 103 is provided. The pallet 101 is provided with a plurality of vertically arranged mounting holes 104, and one of the mounting holes 104 is connected to the connecting hole 103 by a connector 105 to fix the pallet 101 on the first crossbeam 102.

[0033] The first crossbeam 102 has a connecting hole 103, and one or more connecting holes 103 can be provided. Figure 5 The vertical direction shown is the vertical direction. Multiple mounting holes 104 are arranged vertically. The support plate 101 is fixed to the first crossbeam 102 by connecting one of the mounting holes 104 and the connecting hole 103 through a connector 105. The connector 105 can be a bolt.

[0034] Furthermore, by vertically arranging multiple mounting holes 104, mounting holes 104 at different positions in the vertical direction can be connected to connecting holes 103 to adjust the position of the support plate 101 on the first crossbeam 102 to accommodate the cleaning of different types of hoses.

[0035] For example, for a hose with a relatively small inner diameter, the mounting hole 104 near the bottom can be connected to the connecting hole 103. For a hose with a relatively large inner diameter, the mounting hole 104 near the top can be connected to the connecting hole 103, so that the position of the support plate 101 is relatively lower, thereby allowing the hose to be completely immersed in the cleaning solution.

[0036] In some embodiments, combined with Figure 4 and Figure 5 As shown, the tilting frame 100 also includes a second crossbeam 106, a slide rail 107, and a slider 108. The second crossbeam 106 is arranged side-by-side with a gap between it and the first crossbeam 102. The slide rail 107 is disposed on the second crossbeam 106. The slider 108 is slidably connected to the slide rail 107. The slider 108 is connected to a position detection device 109, which is used to detect the position of the cleaning component. The slider 108 slides along the slide rail 107 to adjust the position of the position detection device 109.

[0037] The second crossbeam 106 is arranged side-by-side with a gap between it and the first crossbeam 102, meaning that the second crossbeam 106 and the first crossbeam 102 can be arranged approximately parallel to each other. A slide rail 107 is disposed on the second crossbeam 106, and a slider 108 is slidably connected to the slide rail 107. A position detection device 109 is connected to the slider 108. By sliding the slider 108 along the slide rail 107, the position detection device 109 is moved, thereby adjusting the position of the position detection device 109. The position detection device 109 includes a proximity switch, such as a Hall effect proximity switch.

[0038] For example, two slide rails 107 are provided, spaced apart on the second crossbeam 106, both slide rails 107 being arranged along the length of the second crossbeam 106. Two sliders 108 are correspondingly arranged on the two slide rails 107, and each slider 108 is connected to a position detection device 109. After the hose is fixed to the support plate 101, the two sliders 108 are slid so that the positions of the two position detection devices 109 correspond to the two ends of the hose. When the cleaning component reciprocates within the hose for cleaning, when the cleaning component moves out of one end of the hose, the corresponding position detection device 109 detects the cleaning component and sends a signal to the controller, causing the controller to control the cleaning component to move to the other end of the hose via the drive assembly 200. When the cleaning component moves out of the other end of the hose, the corresponding position detection device 109 detects the cleaning component and sends a signal to the controller, causing the controller to control the cleaning component to move back via the drive assembly 200. By repeating this process, the movement range of the cleaning component is limited by two position detection devices 109, enabling the cleaning component to move back and forth within the hose.

[0039] In some embodiments, combined with Figure 2 , Figure 4 and Figure 5 As shown, the tilting frame 100 also includes a connecting frame 110 and a rotating shaft 111. The connecting frame 110 is located at the end of the first crossbeam 102. The rotating shaft 111 is located on the side of the connecting frame 110 away from the first crossbeam 102, and the rotating shaft 111 is movably connected to the fixed frame 300.

[0040] The connecting frame 110 is located at the end of the first crossbeam 102 and also at the end of the second crossbeam 106. The rotating shaft 111 is located on the side of the connecting frame 110 away from the first crossbeam 102. The rotating shaft 111 is movably connected to the fixed frame 300, so as to realize the flipping frame 100 flipping relative to the fixed frame 300.

[0041] In practical applications, the connecting frame 110 can be provided with multiple first through holes, and the fixing frame 300 can be provided with multiple second through holes. When the rotating shaft 111 rotates relative to the fixing frame 300, so that the position of the tray 101 is inside the cleaning tank 301, the corresponding first and second through holes are connected by bolts to fix the position of the flipping frame 100 relative to the fixing frame 300, facilitating the cleaning of the hose. After cleaning, the bolts are removed, and the rotating shaft 111 rotates relative to the fixing frame 300, so that the position of the tray 101 is outside the cleaning tank 301. The corresponding first and second through holes are then connected by bolts to fix the position of the flipping frame 100 relative to the fixing frame 300, facilitating the disassembly of the hose.

[0042] In some embodiments, combined with Figures 5 to 7As shown, the drive assembly 200 also includes a drive member 202, a drum 203, and multiple guide wheels 204. The drive member 202 is disposed on the tilting frame 100. The drum 203 is connected to the drive end of the drive member 202. The end of the rope 201 facing away from the cleaning component is connected to the drum 203. The multiple guide wheels 204 are spaced apart along the movement path of the rope 201, and the rope 201 is wound around the multiple guide wheels 204. The drive member 202 is used to drive the drum 203 to rotate, so as to wind up and unwind the rope 201 and drive the rope 201 to move along the movement path.

[0043] A drive unit 202 is mounted on the tilting frame 100, and the drive unit 202 can be a stepper motor. A drum 203 is connected to the drive end of the drive unit 202, and the drum 203 can be coaxially mounted with the drive shaft of the drive unit 202 so that the drive unit 202 can drive the drum 203 to rotate. One end of the rope 201 is connected to the drum 203, and the other end is connected to the cleaning component. Multiple guide wheels 204 are spaced apart along the movement path of the rope 201, and the rope 201 is wound around the multiple guide wheels 204 to achieve stable movement of the cleaning component driven by the rope 201. The guide wheels 204 can be U-groove guide wheels. The drive unit 202 drives the drum 203 to rotate, and the drum 203 winds up the rope 201, pulling the rope 201 to move along the movement path to move the cleaning component. When the rope 201 is released from the drum 203, the cleaning component can move in the opposite direction.

[0044] The multiple guide wheels 204 can be a first guide wheel 205, a second guide wheel 206, a third guide wheel 207, and a fourth guide wheel 208. The first guide wheel 205, the second guide wheel 206, the third guide wheel 207, and the fourth guide wheel 208 are arranged sequentially at intervals to guide the rope 201.

[0045] In some embodiments, combined with Figure 5 and Figure 6 As shown, the drive assembly 200 also includes a support frame 209 and a pressure roller 210. The support frame 209 is disposed on the tilting frame 100. The pressure roller 210 is rotatably disposed on the support frame 209 and is adjacent to the drum 203. The pressure roller 210 is used to press the rope 201 against the drum 203.

[0046] The support frame 209 is disposed on the tilting frame 100, or it can be disposed on the outer wall of the drive member 202. The pressure roller 210 is rotatably disposed on the support frame 209. The pressure roller 210 is adjacent to the drum 203. The pressure roller 210 is used to press the rope 201 against the drum 203, so that the rope 201 is stably wound on the drum 203.

[0047] When multiple guide wheels 204 include a first guide wheel 205, a second guide wheel 206, a third guide wheel 207, and a fourth guide wheel 208, the first guide wheel 205 can be movably disposed on the side of the support frame 209 away from the pressure wheel 210. The second guide wheel 206, the third guide wheel 207, and the fourth guide wheel 208 can be respectively disposed on the connecting frame 110.

[0048] In some embodiments, combined with Figures 5 to 7 As shown, the inner surface cleaning device 1 of the hose also includes a limiting piece 211, which is disposed on the flipping frame 100 and located on the side of the guide wheel 204. The limiting piece 211 is used to restrict the rope 201 from coming out of the groove of the guide wheel 204.

[0049] The limiting piece 211 is provided on the tilting frame 100. The limiting piece 211 is located on the side of the guide wheel 204. That is, there is a gap between the limiting piece 211 and the U-shaped groove of the guide wheel 204, which is used to prevent the rope 201 from coming out of the groove of the guide wheel 204, so as to achieve stable operation of the cleaning part.

[0050] In some embodiments, combined with Figure 6 and Figure 8 As shown, the tray 101 defines a receiving groove 112, and the bottom and at least one side wall of the receiving groove 112 are provided with fixing holes 113. The tubing is placed in the receiving groove 112, and a binding member passes through the fixing hole 113 to bind the tubing to the tray 101.

[0051] The tray 101 defines a receiving groove 112. The bottom and at least one side wall of the receiving groove 112 are provided with fixing holes 113. The rubber tube is placed in the receiving groove 112, and a binding member is inserted through the fixing hole 113 to bind the rubber tube to the tray 101, thereby fixing the rubber tube. The binding member can be a flexible steel wire rope.

[0052] For example, the bottom of the receiving groove 112 is provided with a fixing hole 113, and one side of the groove wall of the receiving groove 112 is provided with a fixing hole 113, and the other side of the groove wall is provided with an installation hole 104 for connecting with the first crossbeam 102.

[0053] In some embodiments, combined with Figure 1 and Figure 4 As shown, the drive assembly 200 is provided in two sets, each including a first drive assembly 212 and a second drive assembly 213. The first drive assembly 212 is located at one end of the tilting frame 100, and the second drive assembly 213 is located at the other end of the tilting frame 100. One end of the cleaning component is connected to the rope 201 of the first drive assembly 212, and the other end of the cleaning component is connected to the rope 201 of the second drive assembly 213.

[0054] The first drive assembly 212 is disposed at one end of the tilting frame 100, and the second drive assembly 213 is disposed at the other end of the tilting frame 100. The first drive assembly 212 and the second drive assembly 213 are arranged symmetrically with respect to each other. Specifically, as shown in... Figure 4 As shown, the first drive component 212 and the second drive component 213 are symmetrically arranged with respect to the dashed line L.

[0055] For example, the drive member 202 of the first drive assembly 212 rotates forward to wind the corresponding rope 201 onto the drum 203, while the drive member 202 of the second drive assembly 213 rotates in the reverse direction to release the corresponding rope 201 from the drum 203, thus moving the cleaning component along the first direction. When the cleaning component moves to the point where it is detected by the corresponding position detection device 109, the position detection device 109 sends a signal to the controller. The controller controls the drive member 202 of the second drive assembly 213 to rotate forward to wind the corresponding rope 201 onto the drum 203, while the drive member 202 of the first drive assembly 212 rotates in the reverse direction to release the corresponding rope 201 from the drum 203, thus moving the cleaning component along the second direction. When the cleaning component moves to the point where it is detected by the corresponding position detection device 109, the position detection device 109 sends a signal to the controller. The controller controls the drive component 202 of the first drive assembly 212 to rotate in the forward direction, while the drive component 202 of the second drive assembly 213 rotates in the reverse direction, thus reciprocating to achieve the reciprocating movement of the cleaning component. The first direction movement and the second direction movement are opposite, thereby achieving the reciprocating movement of the cleaning component.

[0056] In this embodiment, the controller includes a chip with logic operation capabilities and corresponding circuitry. The control center includes one or more signal input terminals and one or more signal output terminals. For example, the control center is a microcontroller system, which includes a microcontroller chip of a certain model and corresponding power supply circuits, crystal oscillator circuits, etc. The microcontroller system includes input / output terminals directly connected to the pins of the microcontroller chip, and input / output terminals indirectly connected to the pins of the microcontroller through signal adapters (e.g., relays); or the control center is a programmable logic controller (PLC) system, which includes a central processing unit (CPU) module, analog input modules, analog output modules, digital input modules, and digital output modules, etc.

[0057] In practical applications, the controller can also control the operating parameters of the drive unit 202 to control the moving speed, moving distance, and number of reciprocations of the cleaning component, thereby achieving automatic brushing with multiple reciprocations and improving cleaning quality. The controller can also be connected to a display screen to display information such as the moving speed of the cleaning component.

[0058] In practical applications, steel wire ropes can be installed at both ends of the cleaning component. The steel wire ropes of the cleaning component can be connected to the rope 201 through the quick connector 214 to improve installation efficiency.

[0059] For example, the prepared neutral detergent is poured into the cleaning tank 301. The hose is placed in the receiving groove 112 of the tray 101 and fixed to the tray 101 by the binding. One end of the cleaning component is connected to the rope 201 of the first drive assembly 212, and the cleaning component passes through the inside of the hose. The other end of the cleaning component is then connected to the rope 201 of the second drive assembly 213. The slider 108 moves along the slide rail 107, so that the two position detection devices 109 are respectively located at the two ends of the hose. The slider 108 can be provided with corresponding insertion holes with the slide rail 107. When the position detection device 109 moves to the target position, the corresponding insertion holes are connected by bolts to fix the slider 108 relative to the slide rail 107. The flipping frame 100 is flipped relative to the fixed frame 300, so that the position of the tray 101 is inside the cleaning tank 301, thereby immersing the hose in the detergent in the cleaning tank 301, and fixing the flipping frame 100 relative to the fixed frame 300. The first drive assembly 212 and the second drive assembly 213 drive the cleaning component to reciprocate inside the hose to clean the inner surface of the hose.

[0060] In some embodiments, combined with Figure 2 As shown, the hose inner surface cleaning device 1 also includes a movable caster 500, which is disposed at the bottom of the fixed frame 300.

[0061] The movable casters 500 are located at the bottom of the fixed frame 300 for easy movement and pushing / pulling. The number of movable casters 500 is not limited; for example, it can be four.
