Problems solved by technology

Polyether polyols generally have two types of solid and liquid during storage. Polyether polyols need to be recycled if they are not used for a long time. If a qualitative change occurs, it needs to be recycled through many processes. The existing solid polyether polyol recovery and treatment devices are generally ground, and then the ground material is poured into a pool containing additives for precipitation, grinding Unevenness will cause the material to be difficult to decompose, and it is difficult to take out the recovered material in the sedimentation tank, and the additive and polyether polyol cannot be fully mixed

Abstract

The invention discloses a recovery processing device for producing polyether polyol, and belongs to the technical field of the polyether polyol production. The recovery processing device comprises a material storage tank. The top of the material storage tank is uniformly provided with a fixing block. The top of the fixing block is provided with a stirring box. Middle positions of the stirring boxand the material storage tank are provided with a through pipe. The outer wall of the front side of the through pipe is provided with a control valve. The left side of the top of the stirring box is provided with a feeding port. The outer wall of the right side of the stirring box is provided with an outer protective housing. A cavity of the outer protective housing is provided with a servo motor.The output end of the servo motor is connected with a stirring shaft. The outer wall of the stirring shaft is uniformly provided with a stirring rod. Double times of grinding is performed on the solid polyether polyol, so the solid polyether polyol can be more uniformly ground, and the ground polyether polyol is sieved, so falling of a material is convenient. A material storage box can be individually taken out from the material storage tank, so the material can be adequately mixed with a catalyst, and a finished product is conveniently taken out.

Description

technical field [0001] The invention relates to the technical field of polyether polyol production, in particular to a recovery treatment device and a use method for producing polyether polyol. Background technique [0002] Polyether polyol is one of the main components of making foam. Polyether polyol has excellent properties such as high foaming ratio and light weight. By adding different catalysts to polyether polyol, it can also produce a variety of products with different functions. . Polyether polyols generally have two types of solid and liquid during storage. Polyether polyols need to be recycled if they are not used for a long time. If a qualitative change occurs, it needs to be recycled through many processes. The existing solid polyether polyol recovery and treatment devices are generally ground, and then the ground material is poured into a pool containing additives for precipitation, grinding Inhomogeneity will cause the material to be difficult to decompose, ...
