Whole glass tube processing system of medium-high temperature solar heat collecting tube

Abstract

The invention discloses a whole glass tube processing system of a medium-high temperature solar heat collecting tube. A 280-segment cutting device for cutting a glass tube into 280mm glass segments, a glass tube cutting device for carrying out linearity detection on the 280mm glass segments, sizing the qualified glass segments and cutting into the required glass segments, a glass-kovar sealing device for performing kovar sealing on 280mm glass segments to form 300 segments, a glass-glass sealing device for sealing the 300 segments and the sized and cut glass segments, and a tail pipe sealing device for connecting a tail pipe to the glass segments in a sealing way are sequentially arranged along the glass tube processing direction. According to the whole glass tube processing system of the medium-high temperature solar heat collecting tube, the automation degree in the whole glass tube processing process of the medium-high temperature solar heat collecting tube is improved, use of manpower is greatly reduced, the labor intensity of a worker is reduced, the labor cost is reduced and the production efficiency is greatly improved.

Description

technical field [0001] The invention relates to the field of solar vacuum heat collecting tubes, in particular to a processing system for whole glass tubes of medium and high temperature solar heat collecting tubes. Background technique [0002] At present, most of the whole tube glass processing of domestic medium and high temperature solar collector tubes is done manually and lacks automation. If there are too many manual factors, the quality of the products will be uneven and the efficiency will be very low. The medium and high temperature solar collector tube is used for photothermal power generation. Its structure is double-layer double-ended opening. It is a stainless steel tube with a diameter of 70 mm and a length of 4060 mm. The glass tube with a diameter of 125mm is sealed and connected by a bellows, and then sealed by vacuum exhaust. It uses high-temperature oil as a heat-conducting medium. Compared with ordinary medium and low-temperature heat collecting tubes,...
