Description

Technical Field

[0001] This utility model relates to the field of gas cylinder maintenance technology, and in particular to a gas cylinder cleaning device. Background Technology

[0002] In industrial production and applications, gas cylinders, as specialized equipment for storing various gaseous and liquid media, require meticulous cleaning. With repeated use, various impurities, dirt, and chemicals accumulate inside the cylinders. These residues not only affect the cylinder's lifespan but may also threaten the safety of subsequent gas filling and use. Therefore, regular and thorough cleaning of gas cylinders is essential to ensuring their safety and reliability.

[0003] Traditional manual cleaning methods are time-consuming and labor-intensive, making it difficult to meet the high-frequency and large-volume cleaning demands of modern industrial production. With technological advancements, mechanized gas cylinder cleaning equipment has emerged on the market. This equipment typically uses simple mechanical devices to assist manual labor in completing some cleaning processes, such as using nozzles for high-pressure water rinsing or rotating devices to swirl the cylinders in the cleaning solution to enhance the cleaning effect. However, these semi-automated devices still have many shortcomings. On the one hand, they still require considerable manual intervention during operation, limiting further improvements in cleaning efficiency. On the other hand, their cleaning methods are relatively limited, often failing to effectively clean the complex internal structures and hard-to-reach areas of the cylinders, resulting in incomplete cleaning. Utility Model Content

[0004] To address the problems existing in the background technology, this utility model provides a highly efficient and automated gas cylinder cleaning device to improve the quality and efficiency of gas cylinder cleaning.

[0005] The technical solution is as follows: A gas cylinder cleaning device includes a clamping component and a cleaning component. The cleaning component is located at the bottom of the clamping component and includes a lifting mechanism and a brushing unit, a rinsing unit, and a blowing unit arranged sequentially at the movable end of the lifting mechanism. The clamping component includes a translation mechanism and a clamp arranged at the movable end of the translation mechanism. The clamp holds the gas cylinder and passes it sequentially through the brushing unit, the rinsing unit, and the blowing unit, thereby performing multi-stage cleaning on the gas cylinder.

[0006] Optionally, the lifting mechanism includes left and right columns, a platform, and a counterweight. Two horizontal shafts, an upper and a lower one, are arranged between the left and right columns. Multiple pulleys are respectively arranged on the upper and lower horizontal shafts. The pulleys on the upper and lower horizontal shafts are connected by a belt. The platform and the counterweight are arranged opposite to each other on both sides of the belt. A first slider is arranged on the side of the platform near the left and right columns. Vertical slide rails that cooperate with the first slider are respectively arranged on the left and right columns.

[0007] Optionally, the scrubbing unit, rinsing unit, and blowing unit are arranged at intervals along the horizontal direction of the platform. The scrubbing unit includes a vertically mounted rotating shaft on the platform, a cleaning brush and a first rotating nozzle mounted on the upper end of the rotating shaft. The rotating shaft is driven to rotate by a motor mounted on the platform and is connected to a water supply end. High-pressure water enters the rotating shaft and is sprayed out from the first rotating nozzle. The rinsing unit includes a vertically mounted straight pipe on the platform, with a second rotating nozzle mounted on the upper end of the straight pipe. The straight pipe is connected to a water supply end. The blowing unit includes a vertically mounted hollow pipe on the platform, with one end of the hollow pipe connected to an air compressor.

[0008] Optionally, the translation mechanism includes a vertical plate, a second slider, and a mounting plate. A water outlet is provided on the vertical plate, and a lead screw is horizontally arranged in the elongated hole. A lead screw nut is provided on the lead screw, and one end of the lead screw is connected to a drive motor. The second slider and the mounting plate are arranged opposite to each other on both sides of the lead screw nut. A horizontal slide rail adapted to the second slider is provided on one side of the vertical plate.

[0009] Optionally, the clamp includes an outer frame and a fixed clamping member disposed on the mounting plate. A movable clamping member is disposed on the side of the outer frame opposite to the mounting plate. The gas cylinder is placed between the fixed clamping member and the movable clamping member, and the gas cylinder is clamped by the movable clamping member being relatively close to the fixed clamping member.

[0010] Optionally, the outer frame includes left and right longitudinal arms disposed on both sides of the mounting plate. The ends of the left and right longitudinal arms away from the mounting plate are connected to a horizontal arm by a pin. By pulling out the pin and opening one end of the horizontal arm, the gas cylinder can be placed into or removed from the outer frame.

[0011] Optionally, the fixed clamping member includes a V-shaped clamping plate, which is mounted on the mounting plate by adjusting bolts; the movable clamping member includes a cylinder and a flat clamping plate, the cylinder is mounted on the cross arm, the movable rod of the cylinder passes through the cross arm and extends to one side of the mounting plate, and the flat clamping plate is mounted on the movable rod of the cylinder.

[0012] Optionally, elastic pads are provided on the opposite side of the V-shaped clamp and the flat clamp, respectively.

[0013] The beneficial effects of this utility model are: 1. Through the coordinated operation of the translation mechanism and the lifting mechanism, the gas cylinder passes through the brushing, rinsing and blowing units in sequence to achieve multi-stage cleaning, which improves cleaning efficiency, reduces labor costs, and ensures the consistency and stability of the cleaning effect.

[0014] 2. The lifting mechanism of this utility model adopts left and right columns, a platform, a counterweight, and a belt drive system to ensure the stability and precision of the platform during lifting. The relative arrangement of the platform and the counterweight effectively balances the weight and improves the smoothness of lifting.

[0015] 3. The brushing, rinsing, and blowing units of this utility model are arranged at intervals along the horizontal direction of the platform, realizing the automation and continuity of the cleaning process. The brushing unit drives the cleaning brush and the first rotating nozzle to rotate via a rotating shaft, which, combined with high-pressure water jets, enhances the cleaning effect. The second rotating nozzle of the rinsing unit further rinses the inside of the gas cylinder to ensure no residue remains. The blowing unit, through the cooperation of a hollow tube and an air compressor, achieves rapid drying, improving cleaning efficiency.

[0016] 4. This utility model uses a cylinder to drive a flat clamping plate to clamp and release the gas cylinder. The combination of the V-shaped clamping plate and the flat clamping plate adapts to gas cylinders of different diameters, ensuring clamping stability. The elastic pad prevents damage to the gas cylinder surface during clamping, improving the versatility and safety of the clamp.

[0017] In addition, the outer frame adopts a combination design of left and right longitudinal arms and transverse arms, with the transverse arms being detachable via pin connections. This design facilitates the loading and unloading of gas cylinders and improves operational convenience. Attached Figure Description

Detailed Implementation

[0024] The embodiments of this utility model will be described below with reference to the accompanying drawings.

[0025] like Figure 1-5 The gas cylinder cleaning device shown includes a clamping component and a cleaning component. The cleaning component is located at the bottom of the clamping component and is used to clamp and fix the gas cylinder. The cleaning component is used to clean the inside of the gas cylinder. In actual use, the cleaning component is placed in a sunken depression underground. A pedal 800 is set at the top of the depression. The pedal 800 has a hole that allows the cleaning end of the cleaning component to extend out. The clamping component is set on one side of the pedal 800. The cleaning component includes a lifting mechanism 100 and a brushing unit 200, a rinsing unit 300, and a blowing unit 400 arranged sequentially at the movable end of the lifting mechanism 100. The clamping component includes a translation mechanism 500 and a clamp 600 arranged at the movable end of the translation mechanism 500. The clamp 600 clamps the gas cylinder and passes it sequentially through the brushing unit 200, the rinsing unit 300, and the blowing unit 400, thereby performing multi-stage automatic cleaning of the gas cylinder.

[0026] For details, please refer to the following: Figure 2The lifting mechanism 100 specifically includes left and right columns 110, a platform 120, and a counterweight 130. The left and right columns 110 are stainless steel square tubes. Two horizontal shafts 140 are arranged between the left and right columns 110, one upper and one lower. Multiple pulleys 150 are respectively arranged on the upper and lower horizontal shafts 140. Specifically, in this embodiment, three pulleys 150 are arranged on each of the upper and lower horizontal shafts 140, and the pulleys 150 on the upper and lower horizontal shafts 140 are respectively connected by belts 160. A reduction motor is arranged on one of the columns 110, and the reduction motor is connected to the upper horizontal shaft 140 for transmission. The reduction motor drives the upper horizontal shaft 140 to rotate, realizing the transmission between the pulleys 150 and the belts 160. In addition, it should be noted that the platform 120 and the counterweight 130 are positioned opposite each other on both sides of the belt 160. When the pulley 150 rotates, it drives the belt 160 to run synchronously, which in turn drives the platform 120 and the counterweight 130 to move along the direction of the belt's movement. When the platform 120 rises, the counterweight 130 falls, and vice versa. The relative positioning of the platform 120 and the counterweight 130 effectively balances the weight and improves the stability of lifting. Furthermore, a first slider 170 is provided on the side of the platform 120 near the left and right columns 110, and vertical slide rails 180 that cooperate with the first slider 170 are respectively provided on the left and right columns 110. The slide rail slider configuration further enhances the smooth operation of the lifting mechanism 100. When the platform 120 rises, it drives the brushing unit 200, rinsing unit 300, and blowing unit 400, which are located on the platform 120, to rise and enter the interior of the gas cylinder for cleaning.

[0027] Specifically, the brushing unit 200, the rinsing unit 300, and the blowing unit 400 are arranged at intervals along the horizontal direction of the platform 120, and the cleaning sequence of the gas cylinder is brushing, rinsing, and drying.

[0028] The washing unit 200 includes a rotating shaft 210, a cleaning brush 220, and a first rotating nozzle 230. The rotating shaft 210 is vertically mounted on the platform 120. The cleaning brush 220 and the first rotating nozzle 230 are located at the upper end of the rotating shaft 210. A motor for driving the rotating shaft 210 to rotate is mounted on the platform 120. A bypass pipe is provided on one side of the lower end of the rotating shaft 210. The bypass pipe is connected to the water supply end through a pipeline. High-pressure water enters the rotating shaft 210 and is sprayed out from the rotating nozzle. The cleaning brush 220 has a rope-like structure. When the rotation speed of the rotating shaft 210 reaches a certain value, the rope-like cleaning brush 220 rotates by centrifugal force and comes into contact with the inner wall of the gas cylinder to perform washing. The first rotating nozzle 230 rinses the inner wall of the gas cylinder through a rotating water jet. The first cleaning process of the gas cylinder is completed through the cooperation of the cleaning brush 220 and the first rotating nozzle 230.

[0029] Specifically, the rinsing unit 300 includes a straight pipe 310 vertically mounted on the platform 120. The upper end of the straight pipe 310 is equipped with a second rotating nozzle 320, and the lower end of the straight pipe 310 is connected to the water supply end through a bypass pipe. When the gas cylinder is located above the rinsing unit 300, the second rotating nozzle 320 with stronger pressure will use high pressure to rinse the stains remaining in the first cleaning process, causing them to detach from the cylinder. In addition, the second cleaning process is carried out.

[0030] Specifically, the blowing unit 400 includes a hollow tube vertically mounted on the platform 120. One end of the hollow tube is connected to the air compressor through a bypass pipe. The high-speed airflow provided by the air compressor blows away the water droplets adhering to the gas cylinder, which is also a third cleaning process.

[0031] Through the above three cleaning processes, the gas cylinders can be cleaned automatically and efficiently, which not only saves manpower and resources, but also greatly improves the cleaning speed.

[0032] In a specific embodiment, such as Figure 3 , 4 As shown, the translation mechanism 500 includes a vertical plate 510, a second slider 520, and a mounting plate 530. The vertical plate 510 is disposed on one side of the pedal 800 or on the ground.

[0033] A horizontal elongated hole 511 is provided on the upright plate 510. A lead screw 540 is horizontally arranged in the elongated hole 511, and a lead screw nut 550 is provided on the lead screw 540. One end of the lead screw 540 is connected to the drive motor. The second slider 520 and the mounting plate 530 are arranged opposite each other on both sides of the lead screw nut 550. Specifically, the mounting plate 530 is arranged on the side of the upright plate 510 closer to the cleaning component, and the second slider 520 is arranged on the opposite side. A horizontal slide rail 560 is provided on the upright plate 510, and the second slider 520 is slidably connected to the horizontal slide rail 560. The motor drives the lead screw 540 to rotate, and the lead screw nut 550 drives the mounting plate 530 and the second slider 520 to move along the length direction of the lead screw 540. The clamp 600 is arranged on the mounting plate 530. When the clamp 600 clamps the gas cylinder, it will drive the gas cylinder to move synchronously, so that the gas cylinder passes through three cleaning processes in sequence.

[0034] In another preferred embodiment, the upright plate 510 is replaced by an annular guide rail structure (not shown in the figure), and the pulley structure replaces the lead screw structure (not shown in the figure). By setting multiple mounting plates 530 on the transmission belt of the pulley structure, and setting a clamp 600 on each mounting plate 530, the clamp 600 can be moved cyclically, and each clamp holds a gas cylinder, thus improving the cleaning efficiency.

[0035] like Figure 3As shown, the clamp 600 specifically includes an outer frame 610 and a fixed clamping member 620 mounted on the mounting plate 530. A movable clamping member 630 is provided on the side of the outer frame 610 opposite to the mounting plate 530. The gas cylinder is placed between the fixed clamping member 620 and the movable clamping member 630. The gas cylinder is clamped by the movable clamping member 630 being relatively close to the fixed clamping member 620. (Reference) Figure 5 More specifically, the outer frame 610 includes left and right longitudinal arms 611 disposed on both sides of the mounting plate 530. The ends of the left and right longitudinal arms 611 furthest from the mounting plate 530 are connected to a cross arm 613 via pins 612. The left and right longitudinal arms 611, the cross arm 613, and the mounting plate 530 together form a rectangular frame. When placing or removing a gas cylinder, the pins 612 are pulled out, and then one end of the cross arm 613 is opened. Furthermore, the fixing clamp 620 includes a V-shaped clamp 621 and an adjusting bolt 622. The V-shaped clamp 621 is mounted on the mounting plate 530 via the adjusting bolt 622. Before clamping gas cylinders of different sizes, the distance between the V-shaped clamp 621 and the movable clamp 630 can be adjusted using the adjusting bolt 622 to adjust the position of the gas cylinder opening. Furthermore, the movable clamping component 630 includes a cylinder 631 and a flat clamping plate 632. The cylinder 631 is mounted on the horizontal arm 613, and the movable rod of the cylinder 631 extends through the horizontal arm 613 and toward the mounting plate 530. The flat clamping plate 632 is mounted on the movable rod of the cylinder 631. The extension and retraction of the movable rod of the cylinder 631 controls the distance between the flat clamping plate 632 and the V-shaped clamping plate 621, thereby clamping the gas cylinder. In a preferred embodiment, elastic pads 700 are respectively provided on opposite sides of the V-shaped clamping plate 621 and the flat clamping plate 632. By providing elastic pads 700, damage to the cylinder body can be avoided during clamping.

[0036] The embodiments described above are merely preferred embodiments of the present invention, and while the descriptions are specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that those skilled in the art can make various modifications, improvements, and substitutions without departing from the inventive concept, and these all fall within the protection scope of the present invention. Therefore, the protection scope of this patent should be determined by the appended claims.
