Production equipment of fiber-grade polypropylene

Abstract

The invention discloses production equipment of fiber-grade polypropylene and relates to the technical field of chemical fiber production. The production equipment of the fiber-grade polypropylene comprises a machine body, wherein the machine body comprises a single-screw extruder and a discharging barrel mounted at a discharging port of the single-screw extruder, six conduits connected with the discharging end of the single-screw extruder are fixedly connected in the discharging barrel at equal intervals in a surrounding manner, every two adjacent conduits are communicated through a swan neck, a middle barrel is fixedly connected at the axis of the inner wall of the discharging barrel, and the middle barrel and the conduits are sleeved with water cooling pipes. According to the productionequipment of fiber-grade polypropylene, when spinning temperature is too high, water temperature increases synchronously, so that a flow control mechanism is driven to enable a flow ball to rotate, the flow ball gradually rotates and the pore diameter gradually increases to increase flow of water in the swan necks, the operation rate of a water cooling system is increased, and the water cooling heat exchange method is enhanced by increasing the water flow speed.

Description

technical field [0001] The invention relates to the technical field of chemical fiber production, in particular to a production equipment of fiber-grade polypropylene. Background technique [0002] Polypropylene fiber is a synthetic fiber spun from isotactic polypropylene obtained by propylene polymerization. It has the characteristics of high strength, wear resistance and corrosion resistance. At the same time, it has good wear resistance and resilience, and its chemical resistance is better than ordinary fibers. Chemical Fiber. In the production of polypropylene fibers, spinning is mostly used as the finished product, and at the same time it is convenient for secondary processing. Single-screw extruders are often used for polypropylene fiber production. In the actual production process, there are many variables that can affect the spinning. Among them, the spinning temperature has the greatest impact on the quality of polypropylene fibers. The spinning temperature mainly ...

Problems solved by technology

In the actual production process, there are many variables that can affect the spinning. Among them, the spinning temperature has the greatest impact on the quality of polypropylene fibers. The spinning temperature mainly refers to the temperature in the spinning zone. When the spinning temperature is too high, it will affect the subsequent Spinning cooling and forming will have a great impact, so that the quality of the finished silk output after cooling and forming does not meet the production standards. At the same time, whether the spinning temperature is too high can only be judged by observing the finished product. At this time, a large number of spinning damages have been caused. Production Increased costs and no immediate adjustments when spinning overheats
