Production device and production process of organosilane crosslinked polyethylene insulated overhead insulation cable in one step

Abstract

The invention discloses a production device and production process of an organosilane crosslinked polyethylene insulated overhead insulation cable in one step. The production device comprises a pre-feeding cylinder, a metering feeding cylinder, an extruding machine, a coupling agent metering pump and an accurate metering control device, wherein the outlet of the pre-feeding cylinder is communicated with the inlet of the metering feeding cylinder, a metering screw rod is arranged at the outlet of the metering feeding cylinder, the outlet of the metering feeding cylinder is communicated with a feeding hole of the extruding machine, the outlet of the coupling agent metering pump is communicated with the feeding hole of the extruding machine, the accurate metering control device is used for acquiring parameters of an extruding machine screw rod of the extruding machine and feeding back and controlling the output of the metering screw rod of the metering feeding cylinder and the output of the coupling agent metering pump. With the production device disclosed by the invention, the rotational speed of the screw rod of the extruding machine is acquired, a mixed material and a coupling agent are accurately metered, the production and the final extrusion of the insulation material onto a semiconductor can be completed in one time, and the production cost of the organosilane crosslinked polyethylene overhead insulation cable is greatly reduced.

Description

technical field [0001] The invention relates to a one-step silane crosslinked polyethylene overhead insulated cable production equipment and production process. Background technique [0002] Usually, the production and extrusion process of the one-step silane cross-linked polyethylene overhead insulation material used in the production of one-step silane cross-linked polyethylene overhead insulated cables are separated, which increases transportation and production costs, and may cause damage during transportation. Damage to the packaging of the one-step silane crosslinked polyethylene overhead insulating material causes a decline in material performance, raw materials cannot be used normally, and raw materials that have been unpacked during the production process cannot be stored for a long time. Contents of the invention [0003] The first object of the present invention is to provide a production equipment for one-step production of silane crosslinked polyethylene overh...
