Abstract

The invention belongs to the nylon production technology field and especially relates to a nylon yarn production technology. Drying equipment in the technology comprises a shell, a feed hopper, a discharge hopper, a lead screw, a sliding block, a hinge seat, a mesh plate, a connecting unit, springs, and an elastic screen plate. The lead screw is provided with the sliding block. The connecting unitis used for connecting mesh hole plates. The connecting unit can be extruded and deformed. In the invention, through the hinge seat, the sliding block is connected to one end of each mesh hole plate,the mesh hole plates are connected in series through the connecting unit, the upper portion of the mesh hole plates is connected to the elastic screen plate through one groups of springs. Through making the motors of the two sides of the shell rotate to different directions, the mesh hole plates are continuously swung and then the above elastic screen plate is driven to swing. A nylon slice abovethe elastic screen plate is rolled on the inclined elastic screen plate so that the nylon slice can be uniformly dried. The nylon slice is dried during a rolling process so that drying efficiency ishigh.

Description

technical field [0001] The invention belongs to the technical field of nylon production, in particular to a production process of nylon yarn. Background technique [0002] During the production process, nylon chips still contain 10-15% moisture after extraction and drying steps. Nylon chips with high moisture content cannot be directly used for spinning, and nylon chips need to be dried. The existing drying device is to realize the purpose of drying the nylon chips by using the reverse flow of the nylon chips and the drying gas. During the drying process, whether the distribution of nylon chips in the drying tower is uniform, the flow direction and distribution of high-temperature gas, and the speed of nylon chips entering the drying tower will directly affect the drying speed and efficiency of nylon chips and the moisture content after drying. And then affect the production quality of nylon yarn. [0003] There are also some technical solutions for drying nylon chips in ...
