Polyvinyl chloride powder ingredient stirring device

Abstract

The invention discloses a polyvinyl chloride powder ingredient stirring device and belongs to the technical field of PVC film production equipment. The polyvinyl chloride powder ingredient stirring device is characterized by comprising a vibration screening device, a collection tank, a conveyor and a stirring barrel; the lower end of the vibration screening device is provided with a circular arc-shaped guide plate protruding upwards; the lower end of the vibration screening device is provided with a discharge pipe inclined downwards; the bottom end of the collection tank is provided with a flange used for being connected with the conveyor; the outer side of the collection tank is provided with a fixing rack II used for supporting the collection tank; the lower end of the fixing rack II isprovided with a loadometer; the upper end of the conveyor is provided with a bearing block fixed to a conveying shaft; a dustproof cover is arranged at the tail end of an outlet of the conveyor, and the stirring barrel is arranged at the lower end of the outlet of the conveyor correspondingly. The polyvinyl chloride powder ingredient stirring device achieves the effects of being reasonable in structure design, capable of avoiding pollution to raw materials, high in conveying efficiency, accurate in ingredient stirring and uniform in stirring.

Description

technical field

[0001] The invention relates to the technical field of PVC film production equipment, in particular to a polyvinyl chloride powder batching and stirring device. Background technique

[0002] In the PVC film production industry, the raw materials are generally polyvinyl chloride powder, and the characteristics of polyvinyl chloride powder at different prices are quite different. The two types of polyvinyl chloride powder used in the industry are the largest. The temperature is low, but the finished PVC film generally has ripples, which affects the quality of the product. Another kind of polyvinyl chloride powder has no ripples in the finished PVC film, but the required heating temperature is high. As a result, in the actual production process, the surface temperature of the calendering equipment is high, and it is difficult to clean the calendering rollers, and there is a great risk. If the two kinds of polyvinyl chloride powders are compounded and then produ...
