Description

Technical Field

[0001] This invention relates to the field of pipe cleaning technology, specifically a cleaning device and method for stainless steel pipe processing. Background Technology

[0002] Stainless steel pipes are widely used in chemical, construction, and food processing industries due to their excellent corrosion resistance and mechanical properties. However, during production and processing, oil, dust, and other impurities often adhere to the surface of stainless steel pipes, affecting their subsequent processing and performance. Therefore, developing an efficient stainless steel pipe cleaning device has become an important industry requirement.

[0003] Traditional stainless steel pipe cleaning methods mainly rely on chemical cleaning and manual cleaning. While these methods can remove surface dirt to some extent, they have many drawbacks. Chemical cleaning requires the use of large amounts of chemical reagents, which not only increases production costs but may also pollute the environment. Manual cleaning, on the other hand, is inefficient and cannot guarantee uniformity or thoroughness.

[0004] As industrial automation increases, market demands for cleaning equipment are rising: on the one hand, cleaning equipment needs to be highly efficient and automated to improve production efficiency; on the other hand, the equipment needs to be able to recycle resources to reduce production costs and environmental impact. Summary of the Invention

[0005] The purpose of this invention is to provide a cleaning device and method for stainless steel pipe processing. Through the ingenious design of the cleaning and drying mechanisms, it achieves integrated cleaning, rinsing, and drying operations. A steam generator heats water to form steam, which is then sprayed onto the stainless steel pipes for cleaning. A steam condenser enables steam recovery and recycling, achieving energy conservation and environmental protection. Furthermore, the device employs a mechanical drive, allowing the stainless steel pipes to rotate fully during the cleaning process, ensuring thorough and uniform cleaning. The swaying design during the drying process effectively improves drying efficiency, further enhancing the overall performance and applicability of the machine. Through these innovative designs, this patent provides a highly efficient, environmentally friendly, and automated stainless steel pipe cleaning solution.

[0008] As a further embodiment of the present invention, the second mesh plate is arc-shaped.

[0009] As a further embodiment of the present invention, the driving assembly includes a base, a first gear, a slide bar, a moving frame, teeth, a rack, a first motor, and a second gear. The base is installed at the top of the right side wall of the cleaning tank; the first gear is connected to the bottom of the right side wall of the base via a pin, and the first gear is connected to the right end of the second mesh plate; there are two slide bars, which are respectively inserted into the front and rear sides of the base, and the outer wall of the slide bars is rectangular; the moving frame is installed inside the slide bars; there are several teeth, which are installed from front to back on the upper and lower inner walls of the moving frame; the rack is installed at the bottom of the moving frame, and the rack meshes with the first gear; the first motor is installed on the right side wall of the base; the second gear is installed at the output end of the first motor, and the second gear meshes with the teeth; driven by the first motor, the second mesh plate swings back and forth under the cooperation of the second gear and the teeth, causing the stainless steel pipe to roll, thereby achieving the purpose of thoroughly cleaning the stainless steel pipe.

[0010] As a further embodiment of the present invention, the second gear is a toothed gear.

[0011] As a further embodiment of the present invention, the shaking mechanism includes a box body, limiting rods, a slide block, a pin, a support plate, a top cover, a second motor, a turntable, and a sliding groove. The box body is fixedly connected to the right end of the upper surface of the base. There are two limiting rods, which are respectively fixedly connected to the left and right sides of the inner cavity of the box body. The slide block is slidably fitted onto the outer wall of the limiting rods. The pin is installed at the center of the upper surface of the slide block. There are two support plates, which are respectively vertically fixedly connected to the left and right ends of the upper surface of the slide block, and the top of the support plates is fixedly connected to the lower surface of the drying chamber, so that the slide block and the drying chamber move synchronously. The top cover is installed at the top of the box body. The second motor is installed at the center of the upper surface of the top cover. The turntable is installed at the output end of the second motor, and a sliding groove is opened on the lower surface of the turntable, and the pin is inserted into the inner cavity of the sliding groove. Driven by the second motor, the slide block is shaken back and forth through the cooperation of the sliding groove and the pin, so that the stainless steel pipe moves. This not only rinses thoroughly but also removes water from the surface of the stainless steel pipe, improving drying efficiency.

[0012] As a further embodiment of the present invention, the groove is elliptical in shape and is disposed on the outer wall of the turntable.

[0013] A cleaning method for a stainless steel pipe processing cleaning device includes the following steps:

[0014] Step 1: Opening the cover allows the stainless steel pipe to be placed on the second mesh plate. The water in the storage tank is heated by the steam generator to form steam, which is then transported to the second nozzle. The second nozzle sprays steam onto the stainless steel pipe to clean it. The steam is then recovered into the storage tank by the steam condenser, thus forming a cycle.

[0015] Step 2: The first motor drives the second gear to rotate clockwise. When the second gear alternately drives the teeth of the moving frame at the upper and lower positions, the moving frame can move back and forth. At the same time, the rack pulls the first gear to rotate clockwise and counterclockwise, so as to achieve the purpose of swinging the second mesh plate back and forth. The stainless steel pipe rolls back and forth in the second mesh plate to achieve a thorough cleaning of the stainless steel pipe.

[0016] Step 3: After cleaning, the push plate is pushed to the right by the multi-stage hydraulic cylinder. The push plate pushes the stainless steel tube into the drying box, so that the stainless steel tube falls on the surface of the first mesh plate. The first spray pipe can be connected to the storage box through the delivery pump to rinse the stainless steel, or connected to the external pickling solution to spray pickling solution on the stainless steel tube. Then the air duct blows hot air to the stainless steel tube to dry it.

[0017] Step four: During the rinsing or pickling of the stainless steel pipes, the second motor drives the turntable to rotate, and the inclined slide back and forth presses the pin, causing the slide to move back and forth on the limit rod. The drying box shakes back and forth, causing the stainless steel pipes to roll and collide with each other, which can not only thoroughly rinse the stainless steel pipes, but also shake off the water on the surface.

[0018] Compared with the prior art, the beneficial effects of the embodiments of the present invention are:

[0019] 1. This invention uses a first motor to drive a second gear to rotate. The second gear, in conjunction with the teeth, moves the frame back and forth. The rack and pinion drive the first gear to make the first mesh plate swing back and forth, causing the stainless steel pipes to roll. This achieves steam cleaning of multiple stainless steel pipes and effectively cleans the stainless steel surface.

[0020] 2. This invention uses a second motor to drive the turntable to rotate. The sliding seat moves back and forth along the limit rod in cooperation with the sliding groove and pin, thereby moving the drying box back and forth. The stainless steel tubes roll and collide with each other on the first mesh plate, achieving the purpose of cleaning the stainless steel tubes. It can not only rinse stainless steel but also pickle stainless steel, allowing for a more comprehensive cleaning of stainless steel. Attached Figure Description

[0032] Cleaning: Opening the cover plate 53 allows the stainless steel pipe to be placed on the second mesh plate 55. The water in the storage tank 2 is heated by the steam generator 3 to form steam, which is then delivered to the second nozzle 59. The second nozzle 59 sprays steam onto the stainless steel pipe to clean it.

[0033] Furthermore, the cleaning mechanism 5 includes a cleaning box 51 fixedly connected to the top of the column 4. The bottom of the cleaning box 51 is connected to the top of the steam condenser 6. A horizontal beam 52 is installed at the center of the top of the cleaning box 51. Two cover plates 53 are connected to the front and rear sides of the top of the cleaning box 51 by hinges. A baffle 54 is connected to the bottom of the right side wall of the cleaning box 51 by a hinge. The baffle 54 can prevent steam from spraying out of the cleaning box 51. A second mesh plate 55 is connected to the bottom of the inner cavity of the cleaning box 51 by a pin. The second mesh plate 55 is used to place stainless steel pipes. The second mesh plate 55 is arc-shaped. When the second mesh plate 55 swings, the... The curved surface of the second mesh plate 55 allows the stainless steel pipe to roll, ensuring thorough cleaning. A drive assembly 56 is installed at the top right side wall of the cleaning tank 51, which causes the second mesh plate 55 to swing back and forth. A multi-stage hydraulic cylinder 57 is horizontally installed at the bottom left side wall of the cleaning tank 51, and a push plate 58 is installed at the output end of the multi-stage hydraulic cylinder 57.

When the first motor 567 drives the second gear 568 to rotate clockwise, the second gear 568 contacts the bottom tooth 565, causing the moving frame 564 to move backward. When the second gear 568 contacts the top tooth 565, the moving frame 564 moves forward. Thus, the moving frame 564 moves back and forth.

[0035] Comprehensive cleaning: The first motor 567 drives the second gear 568 to rotate clockwise. When the second gear 568 alternately drives the teeth 565 of the moving frame 564 at the upper and lower positions, the moving frame 564 can move back and forth.
