Description

Haydite proppant semi-manufactured goods drying device Technical Field The utility model relates to the technical field of proppant production, in particular to a ceramic proppant semi-finished product drying device. Background The ceramic grain proppant is artificial ceramic grain produced with bauxite and other material and through high temperature sintering and is used mainly in hydraulic fracturing operation of oil and gas field to support crack and raise the yield of oil and gas well. The drying of the ceramic proppant is a key link in the production process of the ceramic proppant, and the main purpose of the drying is to remove moisture in a ceramic proppant semi-finished product, ensure the stability of chemical components of the ceramic proppant semi-finished product and avoid cracking or strength reduction of the ceramic proppant semi-finished product caused by moisture evaporation in the subsequent high-temperature calcination process. The hot air is contacted with the ceramic proppant semi-finished product, so that the hot air takes away moisture on the ceramic proppant semi-finished product, which is a mode for drying the ceramic proppant semi-finished product, but when the ceramic proppant semi-finished product is dried in a drying device, the contact area with the hot air is small, the contact time is short, the ceramic proppant semi-finished product is difficult to continuously and comprehensively dry by the hot air, and the drying efficiency of the ceramic proppant semi-finished product is low. Disclosure of Invention The utility model provides a device for drying a semi-finished ceramic proppant, which can improve the drying efficiency of the semi-finished ceramic proppant, and solves the problem that the semi-finished ceramic proppant is difficult to continuously and comprehensively contact with hot air when dried.
