Description

Technical Field

[0001] The invention relates to the technical field of metal bellows production equipment, in particular to a cleaning and drying integrated equipment for metal bellows production. Background Art

[0002] Metal bellows is a pipe with a regular wave shape, usually made of stainless steel, carbon steel or other metal materials. These bellows are widely used in industrial fields, especially in situations where a small bending radius, non-concentric axial transmission or irregular turning, expansion and contraction, and absorption of pipeline thermal deformation are required. This makes them widely used in the petroleum, chemical, electric power, nuclear energy and other industries.

[0003] After massive searches, it was found that the prior art publication number is CN115921419A, which discloses that the present invention can effectively clean the internal gaps of the metal bellows, and detect the tensile strength of the metal bellows during the cleaning process, and can simultaneously perform drying treatment in the cleaning box, effectively reducing space occupancy, and the air duct used for drying can also perform air tightness detection on the metal bellows, and can also automatically take and discharge the metal bellows, and the overall production efficiency is relatively high.

[0004] Therefore, based on the above search and in combination with the existing ones, in the process of cleaning the metal bellows, since the tensile properties of the metal bellows are worse than those of the rubber bellows, and the corrugations of the metal bellows cannot reach a uniform opening during the stretching process of the metal bellows, it is impossible to effectively clean the inner and outer corrugation gaps of the metal bellows, which easily leads to unclean cleaning and is inconvenient for later use and storage.

At the same time, if there may be bubbles, inclusions, unfused or uneven materials inside the material, these problems may reduce the performance of the bellows, thereby failing to guarantee the effective use of the metal bellows.

[0031] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0032] As introduced in the background technology, there are deficiencies in the prior art. In order to solve the above technical problems, the present application proposes an integrated cleaning and drying equipment for the production of metal bellows.

[0033] In a typical implementation of the present application, Figure 1-8 As shown, an integrated cleaning and drying equipment for producing metal bellows includes a washer and dryer 1, the washer and dryer 1 includes a washer and dryer shell 9 placed on the ground, a sliding door 10 is slidably connected to one side of the washer and dryer shell 9, a dryer is fixedly installed on the top of the inner wall of the washer and dryer shell 9, and a corrugated pipe 2 to be inspected is fixedly installed inside the washer and dryer shell 9. Specifically, after the corrugated pipe 2 to be inspected is cleaned, the corrugated pipe 2 to be inspected is dried by starting the dryer.

[0034] The fixing mechanism 3 is used to fix the bellows 2 to be inspected of different diameters. The fixing mechanism 3 includes four fixing blocks 15. The outside of the four fixing blocks 15 abuts against one end of the inside of the bellows 2 to be inspected. One side of the four fixing blocks 15 is rotatably connected with a fixing ring 16. The four fixing blocks 15 are all meshed with the fixing ring 16. The fixing mechanism 3 also includes a tilting block 11 fixedly connected to the inside of the washing and drying shell 9. One side of the tilting block 11 is fixedly connected with a telescopic rod 12. The output end of the telescopic rod 12 is fixedly connected with a connecting arm 13. One side of the connecting arm 13 is fixedly connected with a fixed pipe 14. The four fixing blocks 15 are all slidably connected to the inside of the fixed pipe 14. The fixing ring 16 is rotatably connected to the outside of the fixed pipe 14. The outside of the fixed pipe 14 is provided with a first internal drainage groove;

[0035] The above-mentioned structure can be set to fix the corrugated tube 2 to be inspected of any diameter. Specifically, one end of the corrugated tube 2 to be inspected is put on the outside of the fixed tube 14, and the fixing ring 16 is rotated. The rotation of the fixing ring 16 drives the four fixing blocks 15 to slide to the outside of the fixed tube 14. One ends of the four fixing blocks 15 are all in contact with the inner wall of the corrugated tube 2 to be inspected, so as to fix the corrugated tube 2 to be inspected of any diameter.

[0036] The support mechanism 4 is used for targeted cleaning of the inside of the metal bellows. The support mechanism 4 includes a protective sleeve 18 fixedly connected to the inside of the washing and drying shell 9, and a first plate 34 and a second plate 35 are respectively slidably connected to one side of the protective sleeve 18. An adjustment mechanism 8 is fixedly installed on one side of the support mechanism 4. The support mechanism 4 also includes a fixed plate 19 fixedly installed inside the protective sleeve 18, and the top and bottom of the fixed plate 19 are both slidably connected to the sliding plate 22. The insides of the two sliding plates 22 are fixedly connected to a connecting plate 30, and one side of the connecting plate 30 is fixedly connected to a tension spring 31, and one side of the tension spring 31 is fixedly connected to an airtight plate 32, and the airtight plate 32 is airtightly slidably connected to the inside of the sliding plate 22;

[0037] One end of the top sliding plate 22 is connected to a first plate 34, which is slidably connected to the outside of the fixed plate 19 and the bottom sliding plate 22, one end of the fixed plate 19 is connected to a cleaning shell 36, which is slidably connected to the outside of the two sliding plates 22, one end of the bottom sliding plate 22 is connected to a second plate 35, which is slidably connected to the outside of the top sliding plate 22 and the fixed plate 19, and a pressure limiting valve 33 is fixedly installed inside the fixed plate 19;

[0038] The outside of the first plate 34 and the second plate 35 are fixedly connected with an expansion airbag 37, and the inside of the first plate 34 and the second plate 35 are fixedly connected with a plurality of fixed shafts 38, and the plurality of fixed shafts 38 are arranged in a circle, and the outside of the plurality of fixed shafts 38 are fixedly connected with a spiral spring 39, and one end of the spiral spring 39 is fixedly connected to the inner wall of the corresponding expansion airbag 37. A second inner drainage groove is opened on one side of the second plate 35.

[0039] By setting the above-mentioned structure, the inside of the bellows 2 to be inspected can be fixed and supported. Specifically, after the bellows 2 to be inspected is fixed, the telescopic rod 12 is started at this time, and the output end of the telescopic rod 12 drives the connecting arm 13 to move, and the movement of the connecting arm 13 drives the fixed tube 14 to move, and the movement of the fixed tube 14 drives the bellows 2 to be inspected to move to the side close to the protective sleeve 18. When it moves to the required detection position, a cleaning agent is injected into the inside of the fixed plate 19 and the sliding plate 22, and the cleaning agent drives the two airtight plates 32 to slide inside the corresponding sliding plates 22, so that the gas inside the sliding plate 22 is squeezed to the inside of the first plate 34 and the second plate 35, driving the expansion airbag 37 to expand, and the expansion airbag 37 expands to clamp the edge at the two inner corrugations of the bellows 2 to be inspected, thereby completing the support of the clean part of the bellows 2 to be inspected;

[0040] More specifically, the valve pressure of the pressure-limiting valve 33 is greater than the tension of the tension spring 31, so that the two expansion airbags 37 expand first. At the same time, the spiral spring 39 has a certain lateral bending resistance, which can improve the sealing performance and anti-deformation performance of the expansion airbag 37 to the inspected bellows 2.

[0041] The cleaning mechanism 5 is used to clean the inside and outside of the bellows 2 to be inspected. The cleaning mechanism 5 includes a cleaning water tank 43 fixedly connected to the inside of the washing and drying shell 9. One side of the inner wall of the washing and drying shell 9 is fixedly connected to two spray rings 53. The two spray rings 53 are both arranged on the outside of the bellows 2 to be inspected. The cleaning mechanism 5 also includes a reflux pipe 44 connected to one side of the cleaning water tank 43. The bottom of the cleaning water tank 43 is fixedly connected to a sewage treatment tank 45. The sewage treatment tank 45 and the cleaning water tank 43 are connected by a reflux pipe 44. The return pipe 44 is connected, and a water pump 46 is fixedly installed at the output end of the cleaning water tank 43. The output end of the cleaning water tank 43 is connected to the output end of the water pump 46. The output end of the water pump 46 is connected to a water outlet pipe 47. The output end of the water outlet pipe 47 is connected to three water distribution pipes 48. The three water distribution pipes 48 are respectively connected to the corresponding fixed plate 19 and one end of the two sliding plates 22. The output end of the water outlet pipe 47 is connected to a spray pipe 49, and the spray pipes 49 are all connected to two spray rings 53.

[0042] Furthermore, in the above scheme, the inside and outside of the inspected bellows 2 can be accurately cleaned. Specifically, after the bellows 2 to be inspected is stretched, the water pump 46 is started, and the detergent inside the cleaning water tank 43 is pumped into the sewage treatment tank 45 through the reflux pipe 44, and impurities are precipitated inside the sewage treatment tank 45, so that the relatively pure detergent is pumped into the inside of the water outlet pipe 47 through the water pump 46, and then divided into three outputs by the water distribution pipe 48, and the detergent is pumped into the inside of the fixed plate 19 and the two sliding plates 22. When the pressure reaches the valve opening pressure of the pressure limiting valve 33, the high-pressure detergent is sprayed out through the cleaning shell 36, and the stretched position is sprayed with high pressure to clean it, so that the narrow position is cleaned more thoroughly. At the same time, the water outlet pipe 47 also pumps the detergent into the inside of the spray pipe 49, and it is sprayed out by two spray rings 53, and the external corrugations of the inspected bellows 2 after the stretching is completed are sprayed with high pressure to clean it, so that the narrow position is cleaned more thoroughly.

[0043] The inside of the washing and drying shell 9 is fixedly installed with a pneumatic cylinder 17, the inside of the pneumatic cylinder 17 is slidably connected with a piston 27, the top of the piston 27 is fixedly installed with an infrared distance sensor 28 and an air pressure sensor 29, the output end of the pneumatic cylinder 17 is connected with an air pipe 25, the air pipe 25 extends to the inside of the fixed plate 19, the two sliding plates 22 are provided with top grooves 23 on the opposite sides, the two sides of the fixed plate 19 are fixedly connected with top blocks 24, the output end of the air pipe 25 is connected with two telescopic air bags 26, one end of the two telescopic air bags 26 The two top blocks 24 are in contact with the corresponding top blocks 24, and the other ends of the two top blocks 24 are in contact with one side of the inner wall of the corresponding top groove 23. A waterproof groove 50 is fixedly connected to one side of the inner wall of the washing and drying shell 9, and an infrared position sensor 51 is slidably connected inside the waterproof groove 50. A support frame 52 is fixedly connected inside the washing and drying shell 9. Two spray rings 53 are fixedly connected to one side of the support frame 52. The tops of the two spray rings 53 are fixedly connected to the same first inkjet 6, and the tops of the two spray rings 53 are fixedly connected to the same second inkjet 7;

[0044] By setting the above-mentioned structure, the non-compliant position of the bellows 2 to be inspected can be accurately detected, and the cause of the non-compliance can be accurately determined. At the same time, the non-compliant position can be marked for later maintenance. Specifically, after the inside of the bellows 2 to be inspected is propped up by the two inflatable airbags 37, the outer corrugated position of the bellows 2 to be inspected is detected by the infrared position sensor 51, and the piston 27 is started. The piston 27 slides inside the pneumatic cylinder 17. The sliding of the pneumatic cylinder 17 drives the gas inside the pneumatic cylinder 17 to enter the inside of the two telescopic airbags 26 through the air pipe 25. Since one end of the two telescopic airbags 26 abuts against the corresponding top block 24, the two telescopic airbags 26 stretch and drive the two sliding plates 22 to move in the opposite direction. The reverse movement of the two sliding plates 22 can respectively drive the first plate 34 and the second plate 35 to move in the opposite direction, thereby stretching the corrugations of the bellows 2 to be inspected, which is convenient for cleaning the inner corrugations of the bellows 2 to be inspected.

[0045] More specifically, if the bellows may have physical damage during the production process, such as cracks, deep scratches or other significant mechanical damage, this may affect its integrity. At the same time, if there are bubbles, inclusions, unfused or uneven materials inside the material, these problems may reduce the performance of the bellows and make the tensile strength of a certain corrugation of the bellows 2 to be inspected worse, thereby affecting the overall durability.

[0046] It is worth mentioning that since the gas is compressible:

[0047] In the first case, when the tensile strength of a certain corrugation of the inspected corrugated tube 2 is lower than the standard tensile strength, the infrared distance sensor 28 and the air pressure sensor 29 detect that the inspected corrugated tube 2 can be stretched at a long distance and low pressure, so it can be judged that the corrugation here is damaged and thin-walled. At this time, the first inkjet 6 is started to spray the outer corrugation of the inspected corrugated tube 2 for easy search and repair during later maintenance.

[0048] In the second case, when the tensile strength of a certain corrugation of the inspected corrugated tube 2 is higher than the standard tensile strength, the infrared distance sensor 28 and the air pressure sensor 29 detect that the inspected corrugated tube 2 can be stretched only when the air pressure is high at a close distance, so it can be judged that the stretching of this corrugation is relatively hard and has poor durability. The outer corrugation of the inspected corrugated tube 2 is sprayed with color through the second inkjet 7 to facilitate the search and maintenance during later maintenance.

[0049] A driving motor 40 is fixedly installed on one side of the fixed plate 19, and a driving gear 41 is fixedly connected to the output end of the driving motor 40, and the driving gear 41 is rotatably connected to the inside of the fixed plate 19. Adjustment blocks 20 are slidably connected to both sides of the fixed plate 19, and driving racks 42 are fixedly connected to the opposite sides of the two adjustment blocks 20, and the driving gear 41 is meshed with the driving rack 42. One end of the two adjustment blocks 20 is fixedly connected to a tension and compression spring 21, and one end of the two tension and compression springs 21 is fixedly connected to one end of the corresponding sliding plate 22;

[0050] By setting the above-mentioned structure, the bellows 2 to be inspected with different corrugation spacings can be accurately supported. Specifically, when it is necessary to adjust the corrugation spacing of the bellows 2 to be inspected, the drive motor 40 is started at this time, and the output end of the drive motor 40 rotates to drive the drive gear 41 to rotate, and the rotation of the drive gear 41 drives the two drive racks 42 to slide in the opposite direction, and the reverse sliding of the two drive racks 42 drives the two adjustment blocks 20 to slide in the opposite direction, and the reverse sliding of the two adjustment blocks 20 drives the two tension and compression springs 21 to move in the opposite direction, and the reverse movement of the two tension and compression springs 21 drives the two sliding plates 22 to move in the opposite direction, and the reverse movement of the two sliding plates 22 drives the corresponding first plate 34 and second plate 35 to move in the opposite direction, so that adjustment can be made according to the corrugation gap of the bellows 2 to be inspected.

[0051] The working principle of the present invention is as follows: first, the bellows 2 to be inspected is fixed, one end of the bellows 2 to be inspected is sleeved on the outside of the fixed tube 14, and the fixing ring 16 is rotated. The fixing ring 16 rotates to drive the four fixing blocks 15 to slide to the outside of the fixed tube 14, and one end of the four fixing blocks 15 abuts against the inner wall of the bellows 2 to be inspected, so as to fix the bellows 2 to be inspected with any diameter;

[0052] After the bellows 2 to be inspected is fixed, the telescopic rod 12 is started at this time, and the output end of the telescopic rod 12 drives the connecting arm 13 to move, and the movement of the connecting arm 13 drives the fixed tube 14 to move, and the movement of the fixed tube 14 drives the bellows 2 to be inspected to move to the side close to the protective sleeve 18. When it moves to the required detection position, a cleaning agent is injected into the interior of the fixed plate 19 and the sliding plate 22, and the cleaning agent drives the two airtight plates 32 to slide inside the corresponding sliding plates 22, so that the gas inside the sliding plate 22 is squeezed to the inside of the first plate 34 and the second plate 35, driving the expansion airbag 37 to expand, and the expansion airbag 37 expands to clamp the edge at the two inner corrugations of the bellows 2 to be inspected, and completes the support and removal of the clean part of the bellows 2 to be inspected;

[0053] After the bellows 2 to be inspected is stretched, the water pump 46 is started to draw the detergent inside the cleaning water tank 43 into the sewage treatment tank 45 through the reflux pipe 44, and the impurities are precipitated inside the sewage treatment tank 45, so that the relatively pure detergent is pumped into the inside of the water outlet pipe 47 through the water pump 46, and then divided into three outputs by the water distribution pipe 48, and the detergent is pumped into the inside of the fixed plate 19 and the two sliding plates 22. When the pressure reaches the opening pressure of the pressure limiting valve 33, the high-pressure detergent is sprayed out through the cleaning shell 36, and the stretched position is sprayed with high pressure to clean it, so that the narrow position is cleaned more thoroughly. At the same time, the water outlet pipe 47 also pumps the detergent into the inside of the spray pipe 49, and it is sprayed out by two spray rings 53, and the external corrugations of the bellows 2 to be inspected after the stretching are completed are sprayed with high pressure to clean it, so that the narrow position is cleaned more thoroughly.

[0054] After the inside of the bellows 2 to be inspected is stretched out by two inflatable airbags 37, after the outer corrugation position of the bellows 2 to be inspected is detected by the infrared position sensor 51, the piston 27 is started, and the piston 27 slides inside the pneumatic cylinder 17. The sliding of the pneumatic cylinder 17 drives the gas inside the pneumatic cylinder 17 to enter the inside of the two telescopic airbags 26 through the air pipe 25. Since one end of the two telescopic airbags 26 abuts against the corresponding top blocks 24, the two telescopic airbags 26 stretch and drive the two sliding plates 22 to move in the opposite direction. The opposite movement of the two sliding plates 22 can respectively drive the first plate 34 and the second plate 35 to move in the opposite direction, thereby stretching the corrugations of the bellows 2 to be inspected, which is convenient for cleaning the inner corrugations of the bellows 2 to be inspected. After cleaning, the dryer is started to dry the bellows 2 to be inspected.

[0055] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
