Manufacturing system for vacuum glass

Abstract

The invention relates to a manufacturing system for vacuum glass. The system comprises a high-temperature heating box, a low-temperature sealing box and a vacuum pump, wherein a communicated hot air pipe is arranged between the high-temperature heating box and the low-temperature sealing box; the low-temperature sealing box consists of a movable sealing box cover and a pumping box; and the movable sealing box cover and the pumping box are arranged hermetically. The manufacturing system for vacuum glass consists of the high-temperature heating box and the low-temperature sealing box, and a hotair pipeline of the low-temperature sealing box is communicated with a pipeline of the high-temperature heating box, therefore the waste heat of the high-temperature heating box can be fully utilizedby a low-temperature vacuum furnace so as to remove moisture from a vacuum glass vacuum cavity. The manufacturing system for vacuum glass has the advantages of environment friendliness, energy conservation and capabilities of removing the moisture from the vacuum glass and improving the quality of vacuum glass; moreover, the entire manufacturing system is combined organically, so that continuous production of vacuum glass is facilitated, and the production efficiency is increased.

Description

technical field [0001] The invention belongs to the field of vacuum glass, in particular to a vacuum glass manufacturing system. Background technique [0002] At present, the traditional vacuum glass manufacturing method is to lay supports on the substrate glass, and then combine the sheets, seal the edges, make air extraction holes, install air extraction pipes, and place the two pieces of glass flat in the heating furnace for heating and edge sealing. Then take it out for vacuuming, and after fusing the exhaust pipe, vacuum glass can be formed. Alternatively, heating and edge sealing and vacuuming can also be carried out directly in a vacuum heating furnace. The shortcoming that above-mentioned two kinds of methods exist is: 1, in the existing vacuum heating furnace, glass supports are placed parallelly up and down, the spacing between each layer of glass supports is 15-25cm, and each layer of glass supports is equipped with a cooling water device The suction head is con...

Problems solved by technology

The shortcoming that above-mentioned two kinds of methods exist is: 1, in the existing vacuum heating furnace, glass supports are placed parallelly up and down, the spacing between each layer of glass supports is 15-25cm, and each layer of glass supports is equipped with a cooling water device The suction head is connected to the suction pipe installed in the vacuum glass. The vacuum unit is installed outside the furnace, and the vacuum is sealed in the furnace, thus completing the manufacture of vacuum glass. However, this structure makes the unit volume in the furnace set Complicated, few layers, low output; 2. The existing vacuum glass suction head device has a complex structure, difficult connection, easy to break, and water cooling is prone to water leakage and cause accidents; 3. The existing vacuum glass suction pipe It is a through hole. During the cooling process of the vacuum glass after edge sealing, there is still some moisture in the vacuum chamber. Although the moisture can be absorbed by the getter, there is also the problem of insufficient vacuum degree that affects the vacuum. The quality of glass; 4. The existing heating furnace and vacuum furnace have their own functions, basically there is no organic connection, and the energy consumption is relatively large
