Problems solved by technology
[0003] However, in the traditional production process, the quartz glass ultraviolet lamp tube needs to be manually connected to the manual exhaust machine before vacuuming, and then the quartz glass ultraviolet lamp tube at room temperature is heated to a certain temperature and the vacuum is drawn at the same time, while in In this process, because the quartz glass ultraviolet lamp tube needs to be heated at high temperature for a long time, and the heating process takes a lot of time, the energy consumption of the product is high and the production efficiency is low. After a long time of heating, the equipment of the automatic vacuum machine is easy to cause Damage occurs due to prolonged heat, which will lead to a significant drop in processing efficiency

Embodiment
[0027] Embodiment: a kind of processing technology of quartz glass ultraviolet lamp tube, comprises following operation:
[0028] A) Put the quartz glass ultraviolet lamp tube on the material conveying device, and send it into the heating zone by the material conveying device;
[0029] B) In the heating section, the quartz glass ultraviolet lamp tube is heated in a sealed space until the hydroxyl group of the quartz glass ultraviolet lamp tube is released, and the heating temperature in the heating section is in the range of 600-1500 degrees Celsius; The upper and lower surfaces are heated. The heating time of the quartz glass ultraviolet lamp tube is more than 1min.
[0030] C) Transfer the quartz glass ultraviolet lamp tube released from the hydroxyl group from the material transfer device to the adjacent automatic vacuum machine. The temperature in the heat preservation state is not lower than 400 degrees Celsius; 1×10 -1 Pa to 1×10 -5 During the vacuuming process of Pa...

The invention discloses a processing technology of a quartz glass ultraviolet lamp tube, relates to the field of lamp tube processing, and solves the problem that the common quartz glass ultraviolet lamp tube needs to be manually installed on a manual exhaust machine before vacuuming, but the manual installation and Under the processing mode of disassembly, the processing efficiency of the quartz glass ultraviolet lamp tube is low. The main point of the technical solution is to place the quartz glass ultraviolet lamp tube on the material conveying device, and the material conveying device sends it into the heating zone; in the heating zone , the quartz glass ultraviolet lamp tube is heated in a sealed space until the hydroxyl group is released, the quartz glass ultraviolet lamp tube is sent to a vacuum pump, and the vacuum treatment is carried out under the heat preservation state; the cathode electronic powder is electrified and decomposed to activate the cathode electronic powder; Fill inert gas into the quartz glass ultraviolet lamp tube and seal it; in order to achieve fast and efficient production of quartz glass ultraviolet lamp tube and improve the consistency of product quality.
Description
technical field [0001] The invention relates to the technical field of lamp tube processing, in particular to a processing technology of a quartz glass ultraviolet lamp tube. Background technique [0002] Ultraviolet sterilization is a sterilization method that has been used for many years at home and abroad. Compared with other sterilization methods, its advantages are that the sterilization effect reaches more than 99%, low unit cost, easy installation, easy maintenance, and no secondary pollution Wait. At present, in medical treatment, public health safety, edible oil, drinking water, and beverage manufacturing industries, ultraviolet germicidal lamps are often used for sterilization. The ultraviolet germicidal lamp is generally a quartz glass ultraviolet lamp tube, and because there are a large number of hydroxyl groups in the tube wall of the quartz glass ultraviolet lamp tube, and the hydroxyl group will cause serious damage to the vacuum in the quartz glass lamp tube...
