Presintering treatment process of glass batch and device thereof

Abstract

The invention discloses a presintering treatment process of a glass batch and a device thereof, and the process is performed according to the following steps: (1) adding 0.5 wt%-3 wt% of binders and 6 wt%-8 wt% of water into a glass batch, well mixing, pressing into spherical particle materials with a diameter of 3-25 mm; (2) adding the spherical particle materials into a rotary heating furnace, preheating at 1020-1250 DEG C for 0.5-2 hours, adding the sintered densified spherical particle materials into a glass melting furnace from the rotary heating furnace. According to the invention, the decomposition of carbonates in the glass batch is performed outside the glass melting furnace, which greatly reduces the gas content in the glass batch, effectively increases the heat transfer, shortens the time for glass clarification and homogenization, that is, increases the single-line yield and reduces the energy consumption without the enlargement of the glass melting furnace area; the invention can realize the increase of the melting amount by 20%-30% without the enlargement of a current melting furnace scale.

Description

technical field [0001] The invention relates to a flat glass melting technology, in particular to a glass batch pre-burning treatment process and equipment thereof. 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 p...

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 it increases the difficulty of crushing; at the same time, after the crushing process is added, it also causes discontinuity in the production process
