[0022] The present invention will be further described with reference to the accompanying drawings.

[0023] like Figure 1 As shown, a method for preparing a ton barrel comprises the following steps:

[0024] Prepare the top plate, bottom plate and enclosure plate; the top plate, bottom plate and enclosure plate are all cut by laser;

[0025] The top plate and the bottom plate are stretched to obtain the barrel top and the barrel bottom, and the barrel bottom is provided with an inner groove; the surrounding plate is bent to form the barrel body; when the bottom plate is stretched, an upward lower connecting ring is formed around the bottom plate, and then the excess part of the lower connecting ring is cut off; when the top plate is stretched, a downward upper connecting ring is formed around the top plate, and then the excess part of the upper connecting ring is cut off;

[0026] Punch reinforcement bulges on the top and bottom of the barrel respectively;

[0027] Splice the barrel top, barrel bottom and barrel body together and fix them by spot welding;

[0028] The barrel top, barrel bottom and barrel body are fully welded; laser welding is used for full welding, and argon arc welding is used in combination. During welding, atmosphere protection welding is performed, and argon gas is used for atmosphere protection welding.

[0029] Welding accessories get tons of barrels;

[0030] When testing the sealing of ton barrels, first fill the barrels with water, then pass high-pressure gas until the set pressure is reached to check whether the welds are leaking.

[0031] like Figures 2 to 9 As shown, the ton barrel includes a barrel cover 1, an emptying valve 4, a barrel top 1, a barrel body 2, a barrel bottom 3 and a breathing valve 5. The barrel top 1, the barrel body 2 and the barrel bottom 3 are all made of stainless steel. The barrel top 1 and the barrel bottom 3 are both rectangular barrels. The barrel top 1 is provided with an upper connecting ring 10 to form an upper cavity 11. The barrel bottom 3 is provided with a lower connecting ring 30 to form a lower cavity 31. The upper connecting ring 10 and the lower connecting ring 30 are connected to the barrel body 2 by full welding. The barrel body 2 is formed by bending a stainless steel plate, and there is a splicing weld 21 in the middle. The barrel top 1, the barrel body 2 and the barrel bottom 3 form a ton barrel. The barrel bottom 3 and the barrel top 1 are made by stretching.

[0032] like Figure 6 As shown, a top reinforcing protrusion 12 with a circular center is provided at the center of the barrel top 1, and the top reinforcing protrusion 12 is formed by stamping, and the barrel cover 1 is mounted on the top reinforcing protrusion 12. The top reinforcing protrusion 12 increases the strength of the barrel top 1 and reduces deformation.

[0033] like Figure 2 As shown, the breathing valve 5 is installed on the barrel top 1 and is located on the outside of the top reinforcement protrusion 12 to avoid interference with the barrel cover 1.

[0034] like Figures 7 to 9 As shown, the barrel bottom 3 is provided with an inner groove 33 that is recessed into the lower cavity 31. The inner groove 33 is arranged on the lower connecting plate 35 of the barrel bottom 3. It is formed by stretching, so that the inner groove 33 and the barrel bottom 3 form an integral structure, avoiding the use of welding to obtain the inner groove 33, thereby improving the overall strength and reliability of the barrel bottom 3, avoiding the problem of weld leakage caused by too many welds, and reducing costs and welding workload. The inner groove 33 is an arc groove, and a vertical connecting plate 35 is provided at the connection between the inner groove 33 and the barrel bottom 3. Both sides of the inner groove 33 are connected to the lower connecting ring 30 through a transition slope 36, forming a transition structure as a whole, improving strength, facilitating stretching, avoiding cracking, and reducing liquid impact and stress. The connecting pipe 34 is welded on the connecting plate 35, and the connecting plate 35 is provided with a lower through hole that communicates with the lower cavity 31.

[0035] The drain valve 4 is installed on the connecting pipe 34, and the drain valve 4 is located in the inner groove 33 to avoid interference with the outside world, effectively protecting the drain valve 4 and avoiding collision that causes cracking of the pipeline and leakage.

[0036] There is an arc transition connection between the upper connecting ring 10 and the barrel top 1, and there is an arc transition connection between the lower connecting ring 30 and the barrel bottom 3, which can facilitate stretching and avoid stretching cracking. At the same time, the arc transition connection can increase strength, reduce stress concentration, reduce the impact force of the liquid, and improve service life.

[0037] The four faces of the upper connecting ring 10 are provided with a plurality of upper reinforcing protrusions 13 protruding toward the upper cavity 11, and the four sides of the lower connecting ring 30 are provided with a plurality of lower reinforcing protrusions 32 protruding toward the lower cavity 31. The upper reinforcing protrusions 13 and the lower reinforcing protrusions 32 can effectively improve the strength of the upper connecting ring 10 and the lower connecting ring 30 and reduce overall deformation.

[0038] The barrel cover 1 is also made of stainless steel, and the overall structure is conventional technology, which will not be described in detail here.

[0039] The ton barrel has the characteristics of reasonable overall structure, durability, safety, easy cleaning, anti-static and corrosion resistance. The upper and lower covers are formed by stretching, which reduces the number of welds and greatly reduces the risk of leakage during storage and transportation. It is suitable for the storage and transportation of export chemicals and chemical raw materials.
