Processing, conveying and cooling equipment for gypsum production line

Abstract

The invention discloses processing, conveying and cooling equipment for a gypsum production line. The processing, conveying and cooling equipment comprises a cooling box and a conveying hopper; a conveying belt used for conveying gypsum is arranged in the conveying hopper, the conveying hopper penetrates through the two side walls of the cooling box in a sealed mode, and a cooling through opening is formed in the position, located on the upper wall of the cooling box, of the conveying hopper in a penetrating mode; a processing space is formed in the part, located above the cooling through opening, of the cooling box; a connecting space is formed in the part, located below the conveying hopper, of the cooling box; a sealing plate is connected into the processing space in a sealed mode; and a cold air storage cavity is formed in the space, located below the sealing plate, of the processing space; the space, located above the sealing plate, of the processing space is arranged to be an excess material recycling cavity; a cooling structure is arranged in the cold air storage cavity; and a recycling structure is connected into the excess material recycling cavity. The equipment has the advantages that the rapid cooling process is better achieved, the tail gas absorption effect is achieved, and raw material waste and air pollution are avoided.

Description

technical field [0001] The invention relates to the technical field of building material processing, in particular to processing, conveying and cooling equipment for a gypsum production line. Background technique [0002] The use of gypsum as a building material is mainly to convert the existing gypsum in various forms into hemihydrate gypsum. In this process, the gypsum needs to be calcined first and then cooled down. It is difficult to realize from the existing gypsum processing line Rapid cooling of gypsum coming out of the calciner. [0003] After searching, the Chinese authorized patent CN106145724B discloses a mixing, conveying and cooling device for a gypsum processing production line, which belongs to the field of building materials, including a fan, an air supply distributor and a humidifying device, an air supply pipe, a conveying mixer shell, a liner, and conveying and stirring device, air cover, and air outlet pipe; the fan is installed on one side of the convey...

[0003] After searching, the Chinese authorized patent CN106145724B discloses a mixing, conveying and cooling device for a gypsum processing production line, which belongs to the field of building materials, including a fan, an air supply distributor and a humidifying device, an air supply pipe, a conveying mixer shell, a liner, and conveying and stirring device, air cover, and air outlet pipe; the fan is installed on one side of the conveying mixer, and is connected with the air supply distributor and humidification device through the air supply pipe. However, in actual use, there are also the following defects: only cooling by air cooling is not effective under the condition of rapid cooling, and when this prior art is used, it will not be treated in close contact with gypsum. The direct exhaust of the exhaust gas will carry some gypsum residues, which not only wastes raw materials, but also may cause pollution
