Problems solved by technology

However, since the thixotropic agent tank is directly connected to the dilution kettle, a certain amount of thixotropic agent will be adsorbed on the inner wall of the dilution kettle during the production process, resulting in uneven mixing, difficult control of the amount of thixotropic agent added, and product quality differences. bigger

Abstract

The invention relates to a resin production apparatus, comprising a reaction vessel, a dilution vessel communicated with the reaction vessel, a filtering device, a thixotropic agent adding device, an emulsification pump and a delivery pump, wherein the filtering device, the emulsification pump and the delivery pump are successively connected through pipelines, the emulsification pump is provided with a powder inlet, the thixotropic agent adding device is communicated with the powder inlet of the emulsification pump through a pipeline, and the feed inlet of the filtering device and the discharge outlet of the delivery pump are both communicated with the dilution vessel through pipelines, thereby forming a delivery loop. The resin production apparatus provided by the invention has the advantages of a high utilization rate of a thixotropic agent, a good dispersion effect, stable product quality, conservation of energy and environmental protection.

Description

technical field [0001] The invention relates to a resin production equipment, which belongs to the technical field of chemical production equipment. Background technique [0002] During the production of unsaturated polyester resin, the reactants are first put into the reaction kettle for polycondensation reaction. After the reaction is completed for a long time, the product is put into the dilution kettle and the corresponding diluent and thixotropic agent are added, and the mixture is uniformly obtained. the final product. The structure of the alcohol recovery device of the existing reactor is relatively simple, the recovery is not sufficient, waste liquid will be generated, and the energy saving and environmental protection are not enough. The structure of the existing diluting kettle is relatively simple, and the diluent and the thixotropic agent are directly added from the feeding port and dispersed through a long time of stirring, and the dispersion is uneven, the emu...
