Embodiment 1

[0030] Such as Figure 1-2 Shown, a kind of raw material pickling method for glass production mainly comprises the following steps:

[0031] S1, feed material, send the required pickling raw materials into the pickling tank 1 from the feeder 3, and seal the tank mouth;

[0032] S2, heating, heating the pickling tank 1 by introducing hot steam, and continuing to keep warm after heating to 60°C-100°C;

[0033] S3, put in the acid solution, inject an appropriate amount of acid solution into the pickling tank 1, the liquid level above the acid solution just does not pass the nozzle of the acid outlet pipe 12, the composition of the acid solution is: hydrochloric acid 10-15wt%; hydrofluoric acid 3~8wt%; Nitric acid 5~10wt%;

[0034] S4, pickling purification, turn on the circulation pump 5 to circulate the acid solution in the pickling tank 1 and the reflux tank 2 for 6-8 hours, so that the acid solution and the impurities in the raw materials can fully react chemically, and remo...

Embodiment 2

[0045] Such as Figure 3-4 As shown, the difference between this embodiment and embodiment 1 lies in that a plurality of cleaning balls 6 are arranged in the pickling tank 1, and the cleaning balls 6 are made of deformable materials.

[0046]In this embodiment, the cleaning ball 6 can flow in the pickling tank 1 with the pickling liquid, and friction occurs with the raw materials in the process, and since the pickling tank 1 is placed obliquely, the pickling liquid at each horizontal position in the pickling tank 1 If the depth of the liquid surface is different, the water pressure will be different, and the shape of the pickling ball 6 will change due to the change of the water pressure in the pickling tank 1. During the deformation process, it can be squeezed and rubbed with the surrounding raw material particles. , the impurities attached to the surface of the raw material particles are polished and carried to the reflux tank 2, and are absorbed in the filter layer 21, whic...

Abstract

The invention belongs to the field of glass production and processing, and particularly relates to a raw material pickling method for glass production. The method comprises the following steps of: S1,feeding: feeding a to-be-pickled raw material into a pickling tank by a feeder, and sealing an opening of the tank; S2, heating: introducing hot steam to heat the pickling tank, performing heating to60DEG C-100DEG C, and continuously keeping the temperature; S3, acid liquor adding: injecting a proper amount of acid liquor into the pickling tank, and making the liquid level above the acid liquorjust submerge a pipe opening of an acid outlet pipe; S4, pickling purification: starting a circulating pump to enable the acid liquor to circularly flow back for 6-8h in the pickling tank and a refluxtank; S5, acid liquor discharging: discharging the acid liquor in the pickling tank into an acid liquor recycling and storing tank; S6, discharge flushing: after the pickling tank is cooled, flushingthe raw materials with clear water for 2-3 times, and then performing discharging. The pickling solution can circularly flow in the pickling tank, so that the pickling solution is in full contact with the surfaces of the raw materials for reaction, the pickling solution can be in uniform contact with the raw material particles, and the reaction speed of the pickling solution and impurities is increased.

Description

technical field [0001] The invention belongs to the field of glass production and processing, and in particular relates to a raw material pickling method for glass production. Background technique [0002] In the production of glass, quartz sand is an important mineral raw material. Quartz sand mineral raw materials often contain a large amount of metal impurities. During production, the impurities in the quartz sand need to be removed to ensure the quality of glass products. [0003] When the existing pickling tank is pickling, it is difficult for the acid liquid to contact with the quartz sand particles evenly, and its impurities are difficult to fully contact with the acid liquid and are difficult to be dissolved, and the product quality cannot be guaranteed at all; some of them use motor stirring In this way, the surface of the quartz sand is fully contacted and reacted with the acid solution. Although the uniformity of the contact between the acid solution and the quart...
