Problems solved by technology

[0003] At present, when preparing a large vertical cylinder on site, the steel plate is often rolled into an arc shape by a plate rolling machine, and the top of the steel plate is hoisted by a crane at the same time to prevent the cylinder from deforming under the action of gravity and keep the cylinder The shape during rolling, but this method is usually effective for small-diameter cylinders, because small-diameter cylinders have small mass and the cylinder is not easy to deform, but for large-diameter cylinders, the deformation caused by gravity cannot Reply, and there are many processes in the production of the conical filling of the large cylinder, and the smoothness of the top cannot be guaranteed

Embodiment 1

[0040] Such as Figure 1-7 As shown, a manufacturing process of a circular cylinder non-standard equipment includes the following steps:

[0041] (1) Make the first belt plate 1 of a cylinder;

[0042] (2) Making the top plate 2 of the cylinder body, and welding the top plate 2 of the cylinder body with the first belt plate 1 of the cylinder body to obtain the first circular shell;

[0043] (3) Repeat step (1) to produce a second cylinder with a plate, lift the first circular shell to a proper position through the pole lifting device 9 and weld it with the second cylinder with plate to obtain a second round shell Shaped shell;

[0044] (4) According to the height of the used cylinder, repeat step (3) until a circular cylinder with the required height is obtained;

[0045] (5) Fully weld the circular cylinder obtained in step (4) to the bottom plate of the tank.

[0046] Further, the step (1) is prepared through the following steps:

[0047] a. Make the foundation support ...

Embodiment 2

[0061] This embodiment takes the production of a methanol intermediate storage tank of 5,000 cubic vertical cylindrical non-standard storage tanks as an example.

[0062] Such as Figure 1-8 As shown, a manufacturing process of a circular cylinder non-standard equipment, the first step is to manufacture the first belt plate 1 of the cylinder; including the production of the foundation support pier 4, the support pier cylinder 41 is made of φ273*10mm seamless steel pipe, the height is H =500mm, δ=240*240*20mm steel plate is selected for the upper plane steel plate 42 of the supporting pier 4, and δ=300*300*20mm steel plate is selected for the lower plane steel plate 43 of the supporting pier 4, the upper and lower plane steel plates and the seamless steel pipe are fully welded, and the upper plane The steel plate 43 is paid off at the belt plate of the cylinder, and marked outside the line, and the stopper 44 is welded at the marked position. The specification of the stopper 44...

Abstract

The invention belongs to the technical field of round barrel non-standard equipment, and particularly relates to a manufacturing process of round barrel non-standard equipment. The manufacturing process comprises the following steps that (1) a first barrel band plate is manufactured; (2) a barrel top plate is manufactured, and the barrel top plate and the first barrel band plate are welded to manufacture a first round shell; (3) the step (1) is repeated to manufacture a second barrel band plate, the first round shell is lifted to a proper position through a derrick lifting device, and the first round shell and the second barrel band plate are welded to manufacture a second round shell; (4) according to the height of a used barrel, the step (3) is repeated till a round barrel with the required height is manufactured; and (5) full welding is carried out on the round barrel obtained in the step (4) and a tank bottom plate. The manufacturing process has the beneficial effects of being high in efficiency, simple in operation and high in adaptability.

Description

technical field [0001] The invention belongs to the technical field of circular cylinder non-standard equipment, and in particular relates to a manufacturing process of circular cylinder non-standard equipment. Background technique [0002] In the chemical industry, steelmaking, power generation and other industries, it is necessary to be equipped with large cylinder (tank) equipment, such as methanol storage tanks in chemical production, evaporative coolers for steelmaking converters, gas coolers, etc. Due to their large size and weight The size cannot be transported, so it is usually made on-site in the field, and then hoisted, spliced, installed and formed. [0003] At present, when preparing a large vertical cylinder on site, the steel plate is often rolled into a circular arc shape by a plate rolling machine, and the top of the steel plate is hoisted by a crane at the same time to prevent the cylinder from deforming under the action of gravity and keep the cylinder The...
