Description

Technical Field

[0001] The utility model belongs to the technical field of metal can bodies, and in particular relates to an airtightness detection device for a metal can body. Background Art

[0002] Metal tanks are now used in various fields, including food, chemical, energy and other industries. Metal tanks can not only be made into mixing equipment, but also into storage equipment, such as storing some liquids or gases. For the storage of some liquids or gases, the sealing of the tank must be ensured first. Only by ensuring the sealing is normal can the tank be used normally.

[0003] There are many ways to test the air tightness of a tank, such as water injection and gas inflation. Water is injected into the tank to see if water flows out from the outer surface of the tank, thereby determining whether the tank is sealed. For gas inflation, gas is filled into the tank to see if the tank leaks, thereby determining its sealing.

[0004] Although both of the above two methods can detect the sealing of the tank body, the inflation-type detection only relies on observing whether gas is generated outside the tank body, which is easy to miss the location where the sealing problem occurs. For example, the gas outlet volume is very small, which is easy to be ignored. As a result, when the tank body is used subsequently, there will be poor sealing, affecting the normal use of the tank body. Therefore, we propose an airtightness detection device for metal tanks to solve the above problems. Utility Model Content

[0005] The technical problem to be solved by the utility model is to provide a device which has a simple overall structure, is easy to operate and can perform airtightness detection on a tank body while ensuring the sealing of the tank body.

[0006] In order to solve the above technical problems, the utility model provides the following technical solutions:

[0007] A gas tightness detection device for a metal tank body comprises a base plate, a positioning seat is fixedly mounted on the base plate, an air tightness detection mechanism is arranged on the positioning seat, the air tightness detection mechanism comprises an air pump fixedly mounted on the upper surface of the base plate, the air outlet end of the air pump is fixedly connected to an air outlet pipe, the air tightness detection mechanism also comprises a support frame fixedly mounted on the upper surface of the base plate, a transparent cover is installed at the inner side of the support frame, a plurality of round rods are evenly and fixedly arranged inside the transparent cover, and the outer surfaces of the round rods are all tied with a plurality of thin ropes.

[0008] The following is a further optimization of the above technical solution by the utility model:

DETAILED DESCRIPTION

[0024] like Figure 1-6 As shown, an airtightness detection device for a metal tank body comprises a base plate 1, a positioning seat 2 is fixedly mounted on the base plate 1, an airtightness detection mechanism 3 is arranged on the positioning seat 2, the airtightness detection mechanism 3 comprises an air pump 31 fixedly mounted on the upper surface of the base plate 1, the air outlet end of the air pump 31 is fixedly connected to an air outlet pipe 311, the airtightness detection mechanism 3 also comprises a support frame 321 fixedly mounted on the upper surface of the base plate 1, a transparent cover 32 is installed at the inner side of the support frame 321, a plurality of round rods 331 are evenly and fixedly arranged inside the transparent cover 32, and a plurality of thin ropes 33 are tied to the outer surfaces of the round rods 331.

[0025] If the tank leaks, the string 33 will be blown to make it flutter, thereby detecting the tightness of the tank.

[0026] A cylinder 4 is fixedly mounted on one side of the support frame 321 away from the bottom plate 1 , and the telescopic end of the cylinder 4 is fixedly connected to the transparent cover 32 . An opening is provided at the bottom of the transparent cover 32 , and a sealing ring 5 is fixedly connected to the bottom end of the inside of the transparent cover 32 .

[0027] In order to facilitate the air tightness detection of the tank body, the device controls the transparent cover 32 to cover the top of the tank body through the cylinder 4, and installs a sealing ring 5 on the inner side of the transparent cover 32 to ensure the sealing between the transparent cover 32 and the tank body, avoid air leakage, and improve the effect of the tank body sealing detection.

[0028] A cylindrical block 6 is fixedly mounted on the top of the positioning seat 2 , and an air outlet pipe 311 passes through the interior of the positioning seat 2 and the cylindrical block 6 and extends out of the interior of the cylindrical block 6 . The end of the air outlet pipe 311 is fixedly connected to the branch pipe 7 .

[0029] The device tests the sealing of the tank body by inflating air into the interior of the tank body. In order to enable the air outlet pipe 311 to stably inflate air into the interior of the tank body, the device installs the air outlet pipe 311 inside the positioning seat 2 and the cylindrical block 6, and positions the air outlet pipe 311 so that it can stably inflate air into the interior of the tank body.

[0030] The air inlet end of the vacuum fan 31 is fixedly connected to a circular tube 8, the upper surface of the bottom plate 1 is fixedly connected to a vertical rod 9, the inner side of the vertical rod 9 is fixedly connected to a limiting ring 10, the limiting ring 10 is sleeved and connected to the outer surface of the circular tube 8, and the top of the vertical rod 9 is fixedly connected to a filter screen 11.

[0031] With this design, by installing a filter 11 above the circular tube 8, when the outside air is extracted by the vacuum fan 31, the outside impurities can be filtered by the filter 11 and then sucked into the inside of the vacuum fan 31 through the circular tube 8, thereby meeting the use requirements.

[0032] The cylindrical block 6 is provided with a scraper mechanism 12 , which includes a rotating shaft 123 , which is rotatably connected to the inside of the cylindrical block 6 , and a rotating wheel 122 is fixedly connected to the outer surface of the cylindrical block 6 , which matches the position of the branch pipe 7 .

[0033] The upper end of the rotating shaft 123 is fixedly connected to the cylinder 13 , and a plurality of rotating connecting rods 14 are arranged around and at intervals on the cylinder 13 . A cleaning brush 121 is fixedly installed on one end of the connecting rods 14 away from the cylinder 13 .

[0034] The upper surface of the positioning seat 2 is fixedly connected to a sealing gasket 15 , and the upper surface of the cylindrical block 6 is fixedly connected to an air pressure detector 16 . The air pressure detector 16 is electrically connected to a display 17 .

[0035] With such a design, when the rotating shaft 123 is rotated and installed inside the cylindrical block 6, the cleaning brush 121 cleans the outer surface of the sealing ring 5, and removes foreign particles attached to the outer surface of the sealing ring 5, thereby ensuring the sealing between the transparent cover 32 and the tank body, thereby improving the detection effect of the sealing of the tank body and meeting the use requirements.

[0036] When in use, the device is connected to an external power supply, and the bottom of the tank body is not sealed but in an open state. The bottom of the tank body is placed on the upper surface of the positioning seat 2 and in contact with the sealing gasket 15. The bottom of the tank body is sealed by the sealing gasket 15, and then the cylinder 4 is opened. The transparent cover 32 is pushed downward by the telescopic end of the cylinder 4, and the transparent cover 32 is covered on the upper end of the tank body. Under the action of the sealing ring 5, the sealing between the transparent cover 32 and the tank body is enhanced.

[0037] Then turn on the vacuum pump 31. In order to prevent external impurities from being sucked into the vacuum pump 31 and causing damage to the vacuum pump 31, a filter screen 11 is installed at the upper end of the circular tube 8. The filter screen 11 filters out external impurities to prevent them from being sucked into the vacuum pump 31. The vacuum pump 31 draws in external air and continuously transports gas to the inside of the tank. The air pressure inside the tank is detected by the air pressure detector 16 to avoid danger.

[0038] After a certain amount of gas is filled into the tank, the inflation is stopped, and then the thin rope 33 inside the transparent cover 32 is observed. The thin rope 33 will not flutter without gas blowing, and the thin rope 33 will flutter even if there is a breeze. Therefore, by observing whether the thin rope 33 flutters, the sealing of the top of the tank can be detected. After the inflation, let it stand for 5-10 minutes. If the thin rope 33 does not flutter during this period, there is no sealing problem with the tank. Otherwise, there is a sealing problem with the tank.

[0039] After the inspection of the tank body is completed, for the convenience of subsequent use, the tank body is removed from the positioning seat 2, and then the transparent cover 32 is pushed downward by the telescopic end of the cylinder 4, and the transparent cover 32 is moved to the position of the cleaning brush 121, and the cleaning brush 121 is put inside the transparent cover 32, and the cleaning brush 121 is made to contact the outer surface of the sealing ring 5, and then the vacuum pump 31 is turned on, the air outlet pipe 311 is closed, the branch pipe 7 is opened, and the rotating wheel 122 is blown through the branch pipe 7 to make it rotate, which can drive the rotating shaft 123 to rotate, thereby driving the cleaning brush 121 to clean the outer surface of the sealing ring 5, and clean up the impurities on the outer surface of the sealing ring 5 to ensure that the sealing ring 5 is clean for subsequent use, so as to avoid gaps between the transparent cover 32 and the tank body to cause air leakage.

[0040] For ordinary technicians in this field, according to the teachings of the present invention, without departing from the principles and spirit of the present invention, changes, modifications, substitutions and variations made to the implementation methods are still within the protection scope of the present invention.
