A Processing Technology of High Precision Stainless Steel Reactor

Abstract

The invention relates to a machining technology of a high-precision stainless steel reactor. The machining technology comprises steps as follows: a reactor barrel body is machined by adopting a thick walled pipe, an inner wall, an outer wall and a jacket of the thick walled pipe are turned on a lathe, a groove-shaped part is formed on the outer wall surface of the turned barrel body, and the thickness of the barrel wall is controlled to be 20 mm; through holes are formed in the end surface of the lower end of the barrel body in the vertical direction, after hole forming, the jacket is welded at the groove-shaped part to enclose a cavity body for accommodating a thermal fluid, and after welding, the barrel body is transferred to the lathe and the inner diameter of the barrel body is subjected to finish turning; the barrel body is transferred to a computer numerical control machining center after finish turning, and an air feed and discharge port, a steam feed and discharge port, a liquid feed and discharge port and an illuminating lamp port are formed in the upper part of the barrel body through engraving; a temperature electrode port, a pH electrode port, a DO (dissolved oxygen) electrode port, a sampling port and a sight glass observation port are formed in the lower part of the barrel body through engraving. According to the technical scheme, all ports are engraved by adopting a numerical control machine tool, the reactor barrel body cannot deform, the roundness deviation of the reactor barrel body can be controlled in a range of 0.05-0.1 mm, and the polishing smoothness can be improved.

Description

technical field [0001] The invention relates to the production field of chemical reaction equipment, in particular to a processing technology of a high-precision stainless steel reactor. Background technique [0002] figure 1 is a schematic diagram of the structure of a traditional reactor, represented by figure 1 It can be seen that the upper and lower parts of the cylinder body of the reactor need to be welded with many interfaces. The upper part includes: air inlet and outlet, material inlet and outlet, lighting mirror port, spare port, etc., and the lower part includes: temperature electrode port, pH electrode port, DO electrode port , Observe the mirror port, conductivity electrode port, etc. Welding so many interfaces in a small space will inevitably cause deformation of the equipment cylinder, especially if the volume of the reactor is below 100 liters. In addition, the treatment of solder joints after welding is also an extremely difficult task, which is not easy ...

AI Technical Summary

Problems solved by technology

Welding so many interfaces in a small space will inevitably cause deformation of the equipment cylinder, especially if the volume of the reactor is below 100 liters.

In addition, the treatment of solder joints after welding is also an extremely difficult task, which is not easy to polish and polish. These solder joints are the main factors affecting the quality of reactors (mostly pressure vessels)
