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

Embodiment 1

[0025] like figure 1 Show, a device that is decomposed by glass with carbonate melting kiln -rotary heating furnace, which includes a feed device 2. The rotary heating tube with the level of 3 ~ 12 ° incumbent 3. The kiln head sealing device 8 8, Kiln sealing device 11 and burner 4;

[0026] There is a storage compartment 1 at the upper end of the investment device 2, and the lower end is connected to the kiln tail seal device 11;

[0027] The high -end and low -end of the rotary heating cylinder 3 are connected with the kiln tail sealing device 11 and the kiln head sealing device 8 sealing.The sealing device 8 is equipped with flue gas entrance 7 and spherical granular export 9;

[0028] The burner 4 passed through the kiln head sealing device 8 into the rotary heating cylinder 3, with gas imports 5 and air import 6 on the burner 4.

[0029] The length of the rotary heating cylinder 3 is 10 ~ 50 meters, the inner diameter is 1.2 ~ 3.5 meters, the speed is 3 ~ 10 rpm / minutes, the ...

Embodiment 2

[0037] Unlike Example 1::

[0038] (1) The water glass that occupies 1.5WT%of the glass with ingredients is dissolved in the water that occupies 8WT.%of the glass and the ingredients, and then the above water glass solution is mixed into the glass and the material is mixed.The roller suppress it into a spherical material of 5 to 18mm.

[0039] (2) Add the spherical granules to the rotary heating furnace, pre -fever at 1180 ~ 1250 ° C, and add the densely tied spherical granules from the exit of the rotary heating furnace to the glass melting kiln.

[0040] Because the supplementary granular material is 5 ~ 18mm, the pre -fever and decomposition in the turning heating cylinder is about 1 hour.

[0041] The water glass in this embodiment can also be replaced with methyl cellulose.

Embodiment 3

[0043] Unlike Example 1::

[0044] (1) Solk the glass glass with 3WT%of the ingredients in the glass with the glass with the water (80-100 ° C) with the glass and the ingredients, and then mix the above water glass solution toThe roller with a semi -circular concave surface is used to suppress it into a spherical material of 8 ~ 25mm.

[0045] (2) Add the spherical granules to the rotary heating furnace, pre -burned at 1020 ~ 1150 ° C, and the densely tied spherical granules are added from the exit of the rotary heating furnace to the glass melting kiln.

[0046] Because the supplementary granular material is 8 ~ 25mm, the pre -fever and decomposition in the turning heating cylinder is about 1.5 hours.The device of the three groups of practical examples 1 in this embodiment is pre -burned at the same time.

[0047] The water glass in this embodiment can also be replaced with methyl cellulose.

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 present invention involves a melting technology of a flat glass, which specifically involves the pre -fever processing process and its equipment. Background technique [0002] Powder -like coordinated materials are used in tablet glass. This method is to make various raw materials crushed and sieved to a certain granularity, and make powder loose materials.This kind of loose material is prone to layering and flour flying during transportation, storage, etc., and the cooperative material that just enters the kiln can easily be blown up by the flame and bring out the melting kiln.The kiln dumplings and heat storage rooms cause erosion and pollute the environment. [0003] The loose shape of the material is invested into the molten kiln. Due to its low accumulation density, the heating efficiency of the flame on the cooperative material is low.In addition, the cooperation is invested into the molten kiln at a certain thickness. The thermal conductivity in ...
