Abstract

The invention discloses a ceramic body drying pulse air supply technique. According to the technique, the drying process comprises one or more same air supply cycles; and each air supply cycle comprises a forward air supply part and a reverse air supply part, and the air supply direction of the forward air supply part and the air supply direction of the reverse air supply part are opposite. By adopting the technique, the shadow effect easily caused by traditional drying techniques is avoided, the moisture evaporation amount of all parts of a product is mean, the contraction amount is consistent, the product quality is ensured, the body drying qualified rate is increased, the drying cycle can further be greatly shortened by about 40%, and the energy consumption is reduced by about 40%.

Description

technical field

[0001] The invention relates to the field of ceramic manufacturing, in particular to a drying process for a ceramic green body. Background technique

[0002] The most traditional drying room only blows and dries the ceramic body from one direction, and there is a more advanced drying room in which the fan diffuses outward through the hot air cylinder rotating in one direction and dries the body. However, these two drying and air supply methods are very easy to form a "shadow effect", that is, due to the relatively fixed air supply direction, some parts of the product dry too much and turn white, while other parts dry too slowly and remain wet. Black, so it is aptly called the shadow effect. Shadow effect Due to the inconsistent drying speed of various parts of the green body, it is easy to crack the green body. In order to avoid cracking of the green body, it is often necessary to reduce the temperature raising speed and humidity dropping speed during the d...

Embodiment Construction

[0025] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention clearer and clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0026] Such as figure 1 As shown, in a preferred embodiment of the present invention, the drying process lasts about 25 hours, with each cycle lasting about 50 minutes. A drying process roughly includes 30 cycles. In each cycle, it includes forward air supply part and reverse air supply part. The lengths of the forward air supply part and the reverse air supply part are both about 25 minutes. The air supply directions of the forward air supply part and the reverse air supply part are completely opposite.

[0027] Both forward air supply and reverse ...
