Description

Technical Field

[0001] This utility model relates to the field of seamless steel pipe production technology, and in particular to a device for blowing and pre-degreasing seamless stainless steel pipes. Background Technology

[0002] In fields such as energy and chemical engineering, nuclear power generation, aerospace, and high-temperature and high-pressure process industries, high-temperature heat exchangers are core energy conversion devices. Their performance and reliability directly affect the energy efficiency, safety, and operating costs of the entire system. As a key component, the seamless stainless steel tubes used in high-temperature heat exchangers must possess extremely high internal cleanliness. Therefore, before the high-temperature heat exchanger tubes are put into use, they must undergo a very thorough internal cleaning. Pre-degreasing, as the first step in the cleaning process, aims to completely remove more than 95% of grease and solid particulate contaminants. Its effectiveness directly determines the success or failure of subsequent fine cleaning (such as ultrasonic cleaning and electrochemical polishing). In existing technologies, common pre-degreasing methods include immersion, spraying, and circulation.

[0003] Traditional immersion-type seamless stainless steel pipe pre-degreasing treatment devices often leave residual impurities adhering to the inner and outer walls of the seamless stainless steel pipes after immersion cleaning, making it difficult to achieve thorough cleaning of the inner and outer walls. This results in incomplete pre-degreasing treatment, affecting subsequent performance and product quality. Furthermore, traditional methods typically only process one seamless stainless steel pipe at a time, requiring operators to immerse and remove each pipe individually. This method is not only labor-intensive and time-consuming but also cannot meet the needs of large-scale production, leading to low production efficiency and increased production and time costs for enterprises. Therefore, a pre-degreasing device for seamless stainless steel pipes is proposed. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies, such as the tendency for residual impurities to adhere to the inner and outer walls of seamless stainless steel pipes after immersion cleaning, making it difficult to achieve thorough cleaning of the pipe walls. This results in incomplete pre-degreasing treatment of the seamless stainless steel pipes, affecting their subsequent performance and product quality. Furthermore, traditional methods typically only process one seamless stainless steel pipe at a time, requiring operators to immerse and remove each pipe individually for cleaning. This method is not only labor-intensive and time-consuming but also cannot meet the needs of large-scale production, leading to low production efficiency and increased production and time costs for enterprises. Therefore, this invention proposes a pre-degreasing device for seamless stainless steel pipes.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A seamless stainless steel pipe pre-degreasing and rinsing device includes a processing box. A functional box is fixedly connected to one outer wall of the processing box. Three gear tubes are installed inside the functional box, and reciprocating screws are threadedly connected inside the three gear tubes. The top of the reciprocating screws extends through the functional box into the processing box and is fixedly connected to a cleaning block. The teeth of the three gear tubes are engaged with transmission gears. A rotating shaft is fixedly connected to the outer wall of the transmission gears. A driven gear is fixedly connected to the top of the rotating shaft. A chain is engaged with the outer surface of the driven gear. A driving gear is engaged with the outer surface of the chain away from the driven gear. A dual-shaft motor is fixedly connected to one outer wall of the driving gear. A threaded rod is fixedly connected to the output end of the dual-shaft motor away from the driving gear. An air jet assembly is threadedly connected to the outer surface of the threaded rod. A delivery air pipe is fixedly installed at the air inlet end of the air jet assembly. A high-pressure air pump is fixedly connected to the end of the delivery air pipe away from the air jet assembly. The functional box protects the operator and the internal gear assembly, preventing accidental contact and damage to the gear assembly during operation.

[0006] Furthermore, a limiting block is fixedly connected to the bottom of the reciprocating screw, and the bottom of the rotating shaft and the gear tube are rotatably connected to the outer wall of the processing box through bearings. The moving distance of the reciprocating screw is limited by the limiting block.

[0007] Furthermore, a movable seat is provided above the high-pressure air pump, and the bottom of the threaded rod and the jet assembly are both located inside the movable seat. The threaded rod is rotatably connected to the movable seat through a bearing, and both the high-pressure air pump and the movable seat are fixedly connected to the processing box.

[0008] Furthermore, two telescopic cylinders are fixedly installed on the outer wall of the processing box on the side away from the high-pressure air pump. A lifting platform is fixedly connected to the top of the two telescopic cylinders, and a placement platform is fixedly installed on the outer wall of the lifting platform.

[0009] Furthermore, the top two ends of the placement platform are fixedly connected to a fixed frame, and the bottom wall inside the fixed frame is fixedly connected to three placement seats. The top of the fixed frame is threaded with a fastener, and the bottom of the fastener is provided with a movable plate. The bottom of the movable plate is fixedly connected to a telescopic rod, and the outer surface of the telescopic rod is fitted with a return spring. The bottom of the telescopic rod is fixedly connected to a limit rubber wheel. The two limit rubber wheels contact the outer surface of the seamless stainless steel tube, and the rubber material will not squeeze or scratch its outer wall.

[0010] Furthermore, the inner walls on both sides of the fixed frame are provided with limiting grooves, and sliding blocks are slidably connected inside the limiting grooves. The sliding blocks are fixedly connected to the moving plate. The limiting grooves and sliding blocks make the moving plate more stable when it moves.

[0011] Furthermore, a controller is fixedly installed on the outer wall of the functional box. The controller is electrically connected to the dual-axis motor, the high-pressure air pump, and the telescopic cylinder, and the equipment is controlled and adjusted through the controller.

[0012] Furthermore, an inlet pipe is fixedly connected to the left outer wall of the processing box, and a drain pipe is fixedly connected to the right outer wall of the processing box. Cleaning water is injected into the processing box through the inlet pipe, and the processing wastewater is discharged through the drain pipe after the cleaning operation is completed.

[0013] This utility model has the following beneficial effects: 1. In this application, when the dual-axis motor is started, the jet assembly is driven to move horizontally through the threaded rod, high-pressure air pump, and air delivery pipe to clean the outer wall of the seamless stainless steel tube with jets, blowing off the cleaning water and impurities adhering to the outer wall of the seamless stainless steel tube. At the same time, the dual-axis motor also works in conjunction with the drive gear, chain, driven gear, rotating shaft, transmission gear, gear tube, and reciprocating screw to drive the cleaning block to extend into the interior of the seamless stainless steel tube and perform repeated movements to deeply clean the inner wall of the seamless stainless steel tube. This avoids the problem of impurities still adhering to the inner and outer walls of the seamless stainless steel tube after soaking and cleaning, which would cause the problem of incomplete pre-degreasing treatment of the seamless stainless steel tube by blowing and washing.

[0014] 2. In this utility model, the telescopic cylinder, lifting platform, placement platform, fixing frame, placement seat, fasteners, moving plate and limiting rubber wheel are used in combination to quickly fix multiple seamless stainless steel pipes and simultaneously perform soaking, cleaning and pre-degreasing treatment on multiple seamless stainless steel pipes. In addition, the telescopic rod and return spring are used to make the blowing and pre-degreasing device adaptable to stainless steel pipes of different sizes, and effectively prevent damage to seamless stainless steel pipes, thereby improving the yield rate.

Detailed Implementation

[0017] The technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0018] Example 1 like Figure 1 - Figure 5 As shown, the present invention proposes a seamless stainless steel pipe blowing and pre-degreasing device, comprising a processing box 1, a functional box 2 fixedly connected to one side of the outer wall of the processing box 1, three gear tubes 3 inside the functional box 2, a reciprocating screw 4 threadedly connected inside the three gear tubes 3, the top of the reciprocating screw 4 extending through the functional box 2 into the processing box 1 and fixedly connected to a cleaning block 5, a transmission gear 6 meshing with the teeth on the outer surface of the three gear tubes 3, a rotating shaft 7 fixedly connected to the outer wall of the transmission gear 6, a driven gear 8 fixedly connected to the top of the rotating shaft 7, a chain 9 meshing with the outer surface of the driven gear 8, a driving gear 10 meshing with the outer surface of the chain 9 away from the driven gear 8, a dual-shaft motor 11 fixedly connected to one side of the outer wall of the driving gear 10, a threaded rod 12 fixedly connected to the output end of the dual-shaft motor 11 away from the driving gear 10, a jet assembly 13 threadedly connected to the outer surface of the threaded rod 12, a conveying air pipe 14 fixedly installed at the air inlet end of the jet assembly 13, and a high-pressure air pump 15 fixedly connected to the end of the conveying air pipe 14 away from the jet assembly 13.

[0019] The bottom of the reciprocating screw 4 is fixedly connected to the limit block 16, and the bottom of the rotating shaft 7 and the gear tube 3 are rotatably connected to the outer wall of the processing box 1 through bearings.

[0020] A movable seat 17 is provided above the high-pressure air pump 15. The threaded rod 12 and the bottom of the jet assembly 13 are both located inside the movable seat 17. The threaded rod 12 is rotatably connected to the movable seat 17 through a bearing. Both the high-pressure air pump 15 and the movable seat 17 are fixedly connected to the processing box 1.

[0021] In this embodiment, after the seamless stainless steel tubes have completed soaking and cleaning, the telescopic cylinder 18 is activated to lift the placement platform 20 out of the processing box 1 and raise it to a horizontal position where multiple seamless stainless steel tubes and cleaning blocks 5 are level. The controller 28 drives the dual-axis motor 11 to run, causing the dual-axis motor 11 to drive the threaded rod 12 to rotate. The rotating threaded rod 12 drives the jet assembly 13 to move horizontally along the moving seat 17. When the jet assembly 13 moves, the high-pressure air pump 15 is activated to input high-pressure gas into the jet assembly 13 through the air delivery pipe 14, causing the jet nozzles on the jet assembly 13 to spray gas onto the soaked and cleaned seamless stainless steel tubes, blowing off the cleaning water and impurities on their surface. When the dual-axis motor 11 drives the threaded rod 12 to rotate, it also drives the drive gear 10 to rotate. The rotating drive gear 10 drives three meshing driven gears 8 to rotate via chain 9. The rotation of the three driven gears 8 drives the rotating shaft 7 fixed to it to rotate, which in turn drives the transmission gear 6 to rotate. At the same time, the three gear tubes 3 meshing with the transmission gear 6 rotate synchronously. The rotating gear tubes 3 drive the reciprocating screw 4 to move, so that the reciprocating screw 4, carrying the cleaning block 5, extends into the inner wall of the seamless stainless steel tube and performs reciprocating motion, thus deeply cleaning the inner wall of the seamless stainless steel tube. In this way, by cleaning the inner and outer walls of the seamless stainless steel tube at the same time, the cleaning effect of the blowing and pre-degreasing device is enhanced, and the problem of impurities still adhering to the inner and outer walls of the seamless stainless steel tube after soaking and cleaning, which would cause the seamless stainless steel tube to be incompletely cleaned by blowing and pre-degreasing, is avoided.

[0022] Example 2 like Figure 1 - Figure 5 As shown, based on Embodiment 1, two telescopic cylinders 18 are fixedly installed on the outer wall of the processing box 1 on the side away from the high-pressure air pump 15. A lifting platform 19 is fixedly connected to the top of the two telescopic cylinders 18, and a placement platform 20 is fixedly installed on the outer wall of the lifting platform 19.

[0023] The top two ends of the placement platform 20 are fixedly connected to the fixed frame 21. The bottom wall inside the fixed frame 21 is fixedly connected to three placement seats 22. The top of the fixed frame 21 is threadedly connected to the fastener 23. The bottom of the fastener 23 is provided with a movable plate 24. The bottom of the movable plate 24 is fixedly connected to the telescopic rod 25. The outer surface of the telescopic rod 25 is fitted with a return spring 26. The bottom of the telescopic rod 25 is fixedly connected to the limit rubber wheel 27.

[0024] Limiting grooves are provided on the inner walls of both sides of the fixed frame 21. Sliding blocks are slidably connected inside the limiting grooves, and the sliding blocks are fixedly connected to the moving plate 24.

[0025] A controller 28 is fixedly installed on the outer wall of the functional box 2. The controller 28 is electrically connected to the dual-axis motor 11, the high-pressure air pump 15 and the telescopic cylinder 18 respectively.

[0026] A liquid inlet pipe is fixedly connected to the left outer wall of the processing box 1, and a liquid outlet pipe is fixedly connected to the right outer wall of the processing box 1.

[0027] In this embodiment, cleaning water is first injected into the processing box 1 through the inlet pipe. Then, multiple seamless stainless steel tubes are placed equidistantly on the placement seats 22 on the fixed frame 21. By rotating the two fasteners 23, the moving plate 24 is driven to move up and down within the fixed frame 21. The downward moving plate 24 drives the limiting rubber wheel 27 to limit and fix both ends of the seamless stainless steel tubes. After the multiple seamless stainless steel tubes are quickly fixed, the controller 28 is activated to drive the telescopic cylinder 18 to move the lifting platform 19 downward. At the same time, the placement platform 20 is also lowered into the processing box 1, and the multiple seamless stainless steel tubes on the placement platform 20 are soaked and cleaned. In this way, the blowing and pre-degreasing device can pre-degrease multiple stainless steel tubes in one go, which improves the work efficiency. At the same time, the telescopic rod 25 and the return spring 26 can be used to adapt to stainless steel pipes of different sizes and effectively prevent the seamless stainless steel tubes from being pinched, thereby improving the yield rate.

[0028] Although embodiments of the present utility have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present utility, the scope of which is defined by the appended claims and their equivalents.
