[0002] In order to eliminate residual stress from the assembly and welding of spherical tanks, stabilize the geometry of the spherical tanks, improve the microstructure and properties of welded joints and heat-affected zones, reduce hardness, improve plasticity and toughness, further release harmful gases in the weld, and prevent hydrogen embrittlement and cracking of the weld, spherical tank construction requires post-weld overall heat treatment.

[0003] Publication number CN209368314U discloses a spherical tank integral heat treatment device, including an integral spherical tank, a main rod, a connecting rod, a connecting block, and a baffle. Support columns are provided at the bottom of the integral spherical tank. A nozzle is located at the center of the bottom of the integral spherical tank, penetrating the bottom of the integral spherical tank and communicating with it. An operation button is installed on the nozzle. An oil tank is installed on the left side wall of the nozzle below the integral spherical tank. This utility model device combines traditional heat treatment structures in its design. The connecting block and baffle work together to form a cover, dissipating heat evenly from both sides of the baffle, improving the quality of heat treatment. Simultaneously, the design of the main rod, sleeve rod, connecting rod, and hinge shaft facilitates the retrieval of the entire device after treatment, making it convenient for workers to use again. Furthermore, water spray cooling is used for further cooling, resulting in a more efficient and versatile device.

[0004] However, the aforementioned spherical tank integral heat treatment device still has the following shortcomings:

[0005] Although the above-mentioned device can cool the tank by spraying water, the spherical tank is large in size, and the cooling water flows down the outer wall of the tank, resulting in a waste of water resources. In view of this, we propose an integral heat treatment device for spherical tanks that can be cooled quickly. Utility Model Content

[0006] The purpose of this utility model is to overcome the shortcomings of the existing technology, adapt to the needs of reality, and provide a spherical tank heat treatment equipment that facilitates rapid cooling. This solves the technical problem that although the above-mentioned devices can cool the tank by spraying water, the spherical tank is large in size, and the cooling water flows down the outer wall of the tank, resulting in the waste of water resources.

[0007] To achieve the purpose of this utility model, the technical solution adopted by this utility model is as follows: a spherical tank heat treatment device for easy rapid cooling is designed, including a spherical tank body, an upper manhole is provided at the top of the spherical tank body, a lower manhole is provided at the bottom of the spherical tank body, and an adjustment mechanism is provided outside the upper manhole; an air bladder is provided inside the spherical tank body, and a gas supply pipe is connected to the air bladder, and the adjustment mechanism is connected to the gas supply pipe.

[0008] Furthermore, the adjustment mechanism includes a cover plate that engages with the outside of the manhole. Hydraulic cylinders are symmetrically arranged on the surface of the cover plate, and a movable plate is connected to the movable end of the hydraulic cylinder. The movable plate is fixedly connected to the air supply pipe.

[0009] Furthermore, the middle surface of the adjustment mechanism is provided with an auxiliary air intake structure; the auxiliary air intake structure includes an auxiliary cylinder frame, which is sleeved on the outside of the air supply pipe. The outer surface of the air supply pipe is provided with a through hole one, and the outer surface of the auxiliary cylinder frame is provided with a through hole two, with the positions of through hole one and through hole two corresponding to each other.

[0010] Furthermore, the auxiliary air intake structure also includes a limiting ring frame and a limiting block. The limiting ring frame and the limiting block are respectively provided on the air supply pipe. A guide block is fixed on the surface of the auxiliary cylinder frame. The auxiliary cylinder frame is disposed between the limiting ring frame and the limiting block, and the upper and lower ends of the auxiliary cylinder frame are respectively in contact with the limiting block and the limiting ring frame.

[0011] Furthermore, the inner wall of the auxiliary cylinder is in contact with the outer wall of the gas pipeline, and the auxiliary cylinder can rotate along the gas pipeline.

[0012] Furthermore, the cover plate adopts a ring structure, and a filter plate is provided between the cover plate and the auxiliary cylinder frame.

[0013] Furthermore, the auxiliary cylinder frame and the guide block are integrally formed.

[0014] Furthermore, the air supply pipe forms a lifting structure through a movable plate, a hydraulic cylinder, and a cover plate, and the air supply pipe is connected to the airbag.

[0015] Furthermore, the gas supply pipe is fixedly connected to the limiting ring frame and the limiting block.

[0016] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0017] 1) In this utility model, when the spherical tank body is heat-treated, the limiting block and the guide block are staggered in a cross shape. At this time, the first through hole and the second through hole do not overlap, so that the external gas is directly injected into the air bag through the gas supply pipe, causing the air bag to expand and effectively guide the hot gas, thereby improving the heat treatment effect. When the spherical tank body is cooled, the air bag is released and cold air is re-injected into the gas supply pipe. The cold air fills the air bag, which can effectively cool the lower half of the spherical tank body. Then, the auxiliary cylinder is rotated so that the limiting block and the guide block overlap vertically, and the first through hole and the second through hole overlap. Cold air continues to be injected, and the excess cold air enters the upper half of the spherical tank body directly through the flow channel formed by the first through hole and the second through hole, thereby improving the cooling effect of the spherical tank body.

[0018] 2) This utility model effectively drives the movable plate to move up and down through the hydraulic cylinder, thereby driving the air supply pipe and airbag to move up and down, making it easy to adjust the height of the airbag. This allows the airbag and the interior of the spherical tank to form different annular flow channels. The hot airflow entering the interior of the spherical tank through the lower manhole is guided by the airbag and rises evenly along the inner wall of the spherical tank, which can evenly heat the spherical tank, ensure the quality of heat treatment, and improve the efficiency of heat treatment.

[0023] The present invention will be further described below with reference to the accompanying drawings and embodiments:

[0024] A spherical tank heat treatment device for easy rapid cooling, see [link / reference]. Figures 1 to 3 The container includes a spherical tank body 1, an upper manhole 2 at the top of the spherical tank body 1, a lower manhole 3 at the bottom of the spherical tank body 1, an airbag 406 inside the spherical tank body 1, an air supply pipe 405 on the airbag 406, and the air supply pipe 405 is connected to the airbag 406; an adjustment mechanism 4 is provided outside the upper manhole 2, and an auxiliary air intake structure 5 is provided on the middle surface of the adjustment mechanism 4.

[0025] The auxiliary air intake structure 5 includes a limiting ring frame 501, which is fixedly sleeved on the middle surface of the air supply pipe 405. A through hole 502 is provided on the air supply pipe 405 above the limiting ring frame 501. A pair of limiting blocks 503 are provided above the through hole 502. An auxiliary cylinder frame 504 is provided between the limiting ring frame 501 and the limiting blocks 503. A pair of guide blocks 505 are symmetrically fixed on the surface of the auxiliary cylinder frame 504. The upper and lower ends of the auxiliary cylinder frame 504 are respectively in contact with the limiting blocks 503 and the limiting ring frame 501. The auxiliary cylinder frame 504 and the guide blocks 505 are integrally formed. A through hole 506 is provided on the auxiliary cylinder frame 504. In this invention, during heat treatment of the spherical tank body 1, the limiting block 503 and the guide block 505 are staggered in a cross shape. At this time, the first through hole 502 and the second through hole 506 do not overlap, allowing external gas to be directly injected into the air bladder 406 through the gas supply pipe 405, causing the air bladder 406 to expand and effectively guide the hot gas, thus improving the heat treatment effect. When cooling the spherical tank body 1, the air bladder 406 is released and cold air is re-injected into the gas supply pipe 405. The cold air fills the air bladder 406, which can effectively cool the lower half of the spherical tank body 1. Then, the auxiliary cylinder frame 504 is rotated so that the limiting block 503 and the guide block 505 overlap vertically, and the first through hole 502 and the second through hole 506 overlap, and cold air continues to be injected. The excess cold air enters the upper half of the spherical tank body 1 directly through the flow channel formed by the first through hole 502 and the second through hole 506, thus improving the cooling effect of the spherical tank body 1.

[0026] It is worth noting that the adjustment mechanism 4 includes a cover plate 401, which is engaged with the outside of the manhole 2. A filter plate 402 is fixedly connected to the inside of the cover plate 401. A set of hydraulic cylinders 403 are symmetrically arranged on the surface of the cover plate 401. A movable plate 404 is connected to the movable end of the hydraulic cylinder 403. An air supply pipe 405 is fixedly connected to the middle of the movable plate 404. Furthermore, the air supply pipe 405 and the through hole 502 are integrally formed. The air supply pipe 405 is fixedly connected to the limiting ring frame 501 and the limiting block 503 (removable). Furthermore, the inner wall of the auxiliary cylinder frame 504 is in contact with the outer wall of the air supply pipe 405. The auxiliary cylinder frame 504 can rotate along the air supply pipe 405. The air supply pipe 405 forms a lifting structure with the cover plate 401 through the movable plate 404, the hydraulic cylinder 403 and the cover plate 401. This invention effectively drives the movable plate 404 to move up and down through the hydraulic cylinder 403, thereby driving the air supply pipe 405 and the air bag 406 to move up and down, making it easy to adjust the height of the air bag 406. This allows the air bag 406 and the interior of the spherical tank body 1 to form different annular flow channels. The hot airflow entering the interior of the spherical tank body 1 through the lower manhole 3 is guided by the air bag 406 and rises evenly along the inner wall of the spherical tank body 1, which can evenly heat the spherical tank body 1, ensure the quality of heat treatment, and improve the efficiency of heat treatment.

[0027] Working principle: During the heat treatment of the spherical tank body 1, the limiting block 503 and the guide block 505 are staggered in a cross shape. At this time, the first through hole 502 and the second through hole 506 do not overlap, allowing the inflation device to directly inject room temperature gas into the air bladder 406 through the gas supply pipe 405, causing the air bladder 406 to inflate. Then, the hydraulic cylinder 403 drives the movable plate 404 to move up and down, thereby driving the gas supply pipe 405 and the air bladder 406 to move up and down, facilitating the adjustment of the height position of the air bladder 406. This creates different annular flow channels between the air bladder 406 and the interior of the spherical tank body 1, allowing the hot airflow to enter the interior of the spherical tank body 1 through the lower manhole 3. Guided by the airbag 406, the hot airflow rises evenly around the inner wall of the spherical tank body 1, which can evenly heat the spherical tank body 1 and ensure the quality of heat treatment. After the heat treatment is completed, the airbag 406 is released and cold air is refilled into the air supply pipe 405. The cold air fills the airbag 406, which can cool the lower half of the interior of the spherical tank body 1. Then, the auxiliary cylinder frame 504 is rotated so that the limiting block 503 and the guide block 505 overlap vertically, and the through hole one 502 and through hole two 506 overlap, and cold air continues to be filled. The excess cold air enters the upper half of the interior of the spherical tank body 1 directly through the flow channel formed by through hole one 502 and through hole two 506, which improves the cooling effect on the spherical tank body 1.
