A large-scale petrochemical pressure vessel head manufacturing polishing machine

Abstract

The invention relates to the technical field of metal material polishing, and is a large-scale petrochemical pressure vessel head manufacturing polishing machine, which includes a base, an auxiliary unit and a polishing unit. The base is provided with an auxiliary unit and a polishing unit, and the auxiliary unit is located in front of the polishing unit above. The present invention can solve the existing problems: polishing the welded end face of the head with a polishing block held by the worker is prone to the problem of unevenness of the welded end face of the head, and as a pressure vessel, the unevenness of the welded end face will lead to poor sealing performance of the weld, Therefore, the possibility of leakage of petrochemical products is increased, and the welding end face of the head is polished by the workers holding the polishing block. The polishing efficiency is low, which will affect the production efficiency of the pressure vessel, and a large amount of metal will be produced during the polishing process. Dust, metal dust will cause harm to workers' health.

Description

technical field [0001] The invention relates to the technical field of metal material polishing, in particular to a large-scale petrochemical pressure vessel head manufacturing polishing machine. Background technique [0002] A pressure vessel is a closed device that contains gas or liquid and carries a certain pressure. The pressure vessel has a wide range of uses, and it has an important position and role in many sectors such as industry, civil, military, and many fields of scientific research. Among them, the most widely used in the chemical industry and petrochemical industry, pressure vessels in the petrochemical field, mainly used for heat transfer, mass transfer, reaction and other processes, as well as storage and transportation of pressurized gas or liquefied gas. [0003] A pressure vessel generally consists of six parts: a cylinder body, a head, a flange, a sealing element, a connecting pipe and a support. The present invention mainly focuses on polishing the wel...

AI Technical Summary

Problems solved by technology

[0005] However, when the above-mentioned polishing block is used to polish the welded end face of the head of a large petrochemical pressure vessel, there are the following problems: ① Polishing the welded end face of the head with a polishing block held by the worker is prone to the problem of unevenness of the welded end face of the head, and As a pressure vessel, the unevenness of the welding end surface will lead to poor sealing of the welding, thus increasing the possibility of leakage of petrochemical products

[0006] ②The welded end face of the head is polished by the worker holding the polishing block. The polishing efficiency is low, which will affect the production efficiency of the pressure vessel, and a large amount of metal dust will be generated during the polishing process, which will cause harm to the worker's body.
