Glass batch presintering treatment technology

Abstract

The invention discloses a glass batch presintering treatment technology including steps of: (1) blending 1-3 wt% of a binder and 6.5-8 wt% of water to the glass batch with uniform mixing and pressingthe mixture into spherical granules being 5-25 mm; (2) adding the spherical granules into a revolving heating furnace and preheating the material at 1050-1250 DEG C for 1-2 h, then sending the sintered and compacted spherical granules into a glass smelting kiln from the outlet of the revolving heating furnace. In the technology, carbonate decomposition is carried out outside the glass smelting kiln, so that gas content of the glass batch is greatly reduced, heat transfer is effectively enhanced and glass clarifying and homogenizing time is shortened; it is equivalent to increase single-line production yield and reduce energy consumption without enlargement on the area of the glass smelting kiln. The technology can increase smelting capacity by 20-30% without the enlargement on the size ofthe present glass smelting kiln.

Description

technical field [0001] The invention relates to a flat glass melting technology, in particular to a glass batch material pre-burning treatment process. Background technique [0002] Powdery batch materials are used in flat glass. This method is to crush and sieve various raw materials to a certain particle size, and then weigh and mix them to make loose powder materials. This kind of loose material is prone to stratification and powder flying in the process of transportation and storage, and the batch material just entered the kiln is easily blown up by the flame and taken out of the furnace, which not only changes the composition of the glass, but also affects the The large wall of the kiln and the regenerator cause erosion and pollute the environment. [0003] The loose form of the batch material is put into the furnace, and because of its low bulk density, the heating efficiency of the flame on the batch material is low. In addition, the batch material is put into the m...

AI Technical Summary

Problems solved by technology

This patent reduces the dust flying in the glass melting furnace, prolongs the life of refractory materials, prevents the clogging of the regenerator, and reduces the flying loss of batch materials, etc. The sintered block has a certain strength in the hot state of 1000 ℃, so the difficulty of crushing is increased; at the same time, after the crushing process is added, it also causes discontinuity in the production process
