Description

Technical Field

[0001] The invention relates to the technical field of chemical storage tanks, in particular to a storage tank for a chemical production line, a storage tank welding method and welding equipment. Background Art

[0002] Chemical production lines often use storage tanks and storage tanks to store chemical raw materials. Storage tanks can be used to store liquid chemical raw materials, such as oil, natural gas, water and other liquid raw materials. When welding large storage tanks, it is usually segmented welding, that is, after multiple tank bodies are manufactured separately, the multiple tank bodies are welded together in sequence. When the segmented tank bodies of the storage tanks are welded together, the annular joints between the tank bodies are mainly welded. When welding the storage tanks, the annular joints can be welded using automated welding equipment. However, after welding, conventional storage tanks have less or no protection for the welded annular joints, resulting in the storage of liquid raw materials inside the storage tank. The liquid raw materials are easily in contact with the welded annular contact. The annular joint is an inevitable part in the welding process of the storage tank. Welding defects such as incomplete penetration, pores, and slag inclusions may occur during the welding process. In addition, there is usually stress concentration at the welded joints. These areas are more susceptible to corrosion under the action of corrosive media, and the welds and heat-affected zones at the annular joints are usually more susceptible to corrosion than the parent material. This is because the microstructure of the material changes during the welding process, resulting in a decrease in its corrosion resistance, and a local electrolyte environment may form at the annular joint. For example, water or impurities are easily accumulated in the weld depression, forming an oxygen concentration cell or under-scale corrosion. This local corrosion environment will accelerate the corrosion rate of the weld area, resulting in the annular joint of the tank body being more susceptible to corrosion by the internal storage liquid under normal circumstances, resulting in a reduced service life of the tank body and more inconvenience.

[0022] 2. Place two tank bodies on two rollers first. After welding is completed, place a single tank body on the two rollers in turn, so that the welded tank bodies are only welded with a single tank body each time.

[0023] 3. After the annular joint of the tank body is welded, the weld is manually polished, and the height of the pressure wheel, the push wheel and multiple discharge boxes are adjusted, and the sealing tape is attached to the weld, and then the isolation material is introduced into the space between the two sleeve rings by the discharge box.

Then start the hydraulic cylinder to push the adjacent sliding rings to move, so that the sliding rings drive the abutment rollers through the support arms and the connecting arms to clamp the inner walls of the adjacent tank bodies, thereby fixing the tank body and the abutment rollers to each other. Then, after inserting the two ends of the rod body into the clamping holes, insert the pins into the positioning holes on the rod body and the support plate, thereby fixing the position of the rod body and the welding mechanism. Then, when the tank body is driven to rotate by the rollers, the two sleeves rotate synchronously through the sliding rods and the fixed cylinders, thereby causing the tank body on the rollers to rotate synchronously, thereby positioning the tank body on the rollers and keeping the tank body on the rollers synchronous when rotating.

DETAILED DESCRIPTION

[0034] 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.

[0035] See also Figure 1-Figure 8 In an embodiment of the present invention, a storage tank welding method for a chemical production line includes a plurality of tank bodies 100 arranged transversely in sequence, including:

[0036] Step 1: Place multiple tank bodies 100 on the welding equipment in sequence, and manually weld collars 110 on the inner walls of two adjacent tank bodies 100, and collars 110 are provided on opposite sides of the annular seam between the two adjacent tank bodies 100;

[0037] Step 2: Use welding equipment to seal the space between the two collars 110 on opposite sides of any annular seam, thereby reducing the corrosion of the liquid inside the storage tank on the joint of the tank body 100 and increasing the service life of the tank body 100;

[0038] The welding equipment used in the welding method of storage tanks for chemical production lines includes:

[0039] A driving mechanism 200 for driving a plurality of tank bodies 100 to rotate, a positioning mechanism 300 for synchronously rotating a plurality of tank bodies 100, and a welding mechanism 400 for closing the space between two adjacent rings 110, wherein the driving mechanism 200 is located below the plurality of tank bodies 100, the positioning mechanism 300 is located inside the plurality of tank bodies 100, the welding mechanism 400 is fixedly connected to the positioning mechanism 300, the welding mechanism 400 comprises a connecting rod 410, and the top end of the connecting rod 410 is fixedly connected to the positioning mechanism 300, and the bottom end is fixedly connected to a connecting plate 411, and a plurality of connecting boxes 420 are fixedly connected to the bottom surface of the connecting plate 411, wherein automatic winding devices are arranged inside the two connecting boxes 420 at the two ends, and connecting tubes are fixedly connected to the bottom surfaces of the plurality of connecting boxes 420 in the middle, the two automatic winding devices are respectively fixedly wound with a welding belt 422 and a sealing belt 421, and isolation materials are arranged inside the plurality of connecting boxes 420 in the middle.

[0040] Specifically, when welding the storage tanks, firstly, the two tank bodies 100 are hoisted onto the driving mechanism 200, and then the collars 110 are manually welded to the inner side walls of the two tank bodies 100, so that the annular seam between the two tank bodies 100 is located in the space between the two collars 110, and after the annular seam between the two tank bodies 100 is welded and the space between the two collars 110 is closed by the welding mechanism 400, the remaining tank bodies 100 are hoisted onto the driving mechanism 200 in turn for welding, so that the welded tank bodies 100 are only welded to one unwelded tank body 100 at a time, and the collar 110 has a moderate thickness, which is convenient for the user to manually use a welding gun to weld the collar 110. 10 is welded on the inner wall of the tank body 100, and the welding quality is guaranteed. When the annular seam between two adjacent tank bodies 100 is welded, the annular seam can be welded by the welding mechanism 400 first, and then the user grinds the welded annular seam, and then the sealing tape 421 is released by the automatic winding device, and the sealing tape 421 is attached to the welded weld for shielding. The sealing tape 421 is soft, and the sealing tape 421 can be a sealing tape. The contact surface between the sealing tape 421 and the inner wall of the tank body 100 has glue and can be attached to the tank body 100, so that the sealing tape 421 shields and protects the welding area, and then Then, the isolation material is added between the two sleeve rings 110 on the opposite sides of the welded annular seam, so that the isolation material fills the space between the two sleeve rings 110, and the isolation material presses the sealing tape 421, which has a secondary fixing effect on the sealing tape 421, and then the welding tape 422 is released by the automatic winding device, so that the welding tape 422 is stuck between the two sleeve rings 110, and the welding tape 422 is used to press the isolation material. At the same time, the isolation material can support the welding tape 422. The welding tape 422 is made of metal material, and the welding tape 422 can be welded to the two sleeve rings 110, so that the isolation material is covered and fixed by the two sleeve rings 110 and the welding tape 422. When the belt 422 is welded to the ring 110, the isolation material can insulate the welding belt 422 to prevent the temperature of the welding belt 422 from affecting the sealing belt 421. The welding belt 422 can be made of metal materials with good plasticity such as copper and aluminum. The isolation material can be made of materials such as quartz sand. The automatic winding equipment is a prior art and will not be described in detail here. The sealing belt 421 is used to protect the annular joint of the tank body 100, and the two rings 110, the welding belt 422, and the isolation material are used to assist in fixing and protecting the sealing belt 421, thereby reducing the contact between the annular seam of the tank body 100 and the internal stored liquid, thereby improving the service life of the tank body 100.

[0043] In this embodiment, the annular seam can be pre-welded by the automatic welding device on the sliding box 480. When the sealing tape 421, the welding tape 422 and the isolation material are arranged between the two rings 110, the positions of the two guide rods 481 are fixed in advance according to the position of the joint between the welding tape 422 and the two rings 110, and the guide rods 481 are screwed into the screw holes on the sliding box 480 by means of screws or other connecting parts for fixing. The connecting rod 410 always remains perpendicular to the ground, and the multiple connecting boxes 420 remain in a downward state.

Then the user uses the pin to pass through the connecting through hole on the box body 440 and the jack on the guide plate 441 to press the pressure wheel, the resisting wheel and the multiple discharge boxes 450. The position of a discharge box 450 is fixed, and the discharge box 450 can allow the isolation material to be put into the space between the two rings 110 through the connecting pipe. The metal rod can be a universal tube if it is thin, or it can be made of a metal material with strong plasticity. The user can manually bend the metal rod to adjust the position of the scraper 451, so that the scraper 451 scrapes off excess isolation material. Then, when the tank body 100 is driven to rotate by the driving mechanism 200, the welding belt 422 can be naturally laid on the isolation material and supported by the isolation material, and is shaped due to the pressure of the wheel. Then, when the welding belt 422 rotates with the tank body 100 and passes through the welding box 490, the joint between the welding belt 422 and the two rings 110 can be welded by an automatic welding device. The automatic welding device is a prior art and will not be described in detail here. Therefore, the annular seam can be pre-welded by the automatic welding device, and an automatic welding device can be added to automatically weld the joint between the welding belt 422 and the ring 110. The U-shaped plate 461 can limit the welding belt 422.
