Method for slicing unused polyester melt for spinning

Abstract

The invention discloses a method for slicing unused polyester melt for spinning. The method comprises the following steps: firstly, providing an anti-clogging polyester dicing machine which comprises a drying device, a water conveyer system, a sized dicing device and a cast strip plate conveyer system;, wherein the sized dicing device comprises a cooling device, the cast strip plate conveyer system is connected with the cooling device, the sized dicing device is connected with the drying device through the water conveyer system, the water conveyer system comprises a water pipe, a water intake device is arranged on the water pipe and comprises a conduit, and a hand valve is arranged on the conduit; 2, slicing the unused melt for spinning in the sized dicing device after the unused melt is cooled by the cooling device, and simultaneously, timely turning on or turning off the hand valve on the conduit according to the slicing amount; 3, conveying the slices into the drying device through the water conveyer system, and then dewatering and drying the slices in the drying device. By the method disclosed by the invention, the water of the water conveyer system can be timely adjusted, the problems of blocking of a water pipeline and increasing of scraps when the yield of a dicing machine is increased are solved, and the production stability is improved.

Description

technical field [0001] The invention relates to the field of chemical polyester production, in particular to a method for cutting unused polyester melt into slices. Background technique [0002] In the chemical polyester production process, the polyester melt that cannot be used up for spinning is sliced ​​in a pelletizer, and it is measured and packaged after drying. A granulator used in a commonly used slicing method in the prior art, such as figure 1 As shown, the granulator includes a drying device 1, a water delivery system 2, a granulation device 3 and a casting belt conveying system 4, and the melt that cannot be used for spinning is discharged from the casting belt conveying system 4 and falls on the pelletizing machine. On the cooling device (not shown in the figure) of the device 3, the melt enters the pelletizing device 3 through the effect of the water flow after being cooled in the cooling device, and after the melt is cut into slices in the pelletizing device ...

AI Technical Summary

Problems solved by technology

[0003] The purpose of the present invention is to provide a kind of method that can timely adjust the water quantity in the water conveying system, the cooling effect is good and the operation is easy to make the unused polyester melt of spinning into slices, thereby solving the problem of the prior art method During the granulation process, the pipeline of the water delivery system is blocked due to the increase in slice output, and directly increasing the water volume may cause problems such as jumping and stopping of the granulator
