Description
Technical field
The present invention relates to cable production field, be specifically related to a kind of three-layer co-extruded cross-linking cable production line.
Background technology
Cable includes that power cable, communication cable, mine cable, removal cable, cable for ship, submarine cable, high pressure are super
High tension cable, optical cable, add electric heating cable, lightning protected cable etc., be power transmission and the important equipment of information transmission.Cable is by wire
Constituting with integument, the insulating barrier that integument is mainly surrounded by materials such as rubber, resin, polyethylene, being additionally provided with of having has
Electric conductivity screen layer, and the overcoat that intensity is higher.The production process of cable is: the material of integument is by extruder warm
Melt and be sent to head and converge with wire, by the mould in head, wrapper material is wrapped up outside wire.Due to integument
Rubber-plastics material be all macromolecular material, its internal microstructure broadly falls into linear structure, and intensity is the lowest, it is impossible to use, must
Must be through over cure or crosslinking, forming network structure could use.Former process names continued to use by ordinary rubber cable, is referred to as " sulfur
Change ", plastic cable is referred to as " crosslinking ", and both do not have this qualitative difference, during conventional " crosslinking " refers to sulfuration, crosslinking in engineering
Plant or two kinds.The most more advanced vulcanization crosslinking technique is high-temperature process, i.e. the cable of molding is through with steam or nitrogen being
Heat-conducting medium add pipe line, macromolecule material internal structure under the high temperature conditions changes, formed network structure.Due to sulfur
Changing or time that crosslinking needs is longer, production efficiency to be improved is it is necessary to use and longer add pipe line, and general adds pipe line all
Reach more than hundred meters.Owing to entering the cable integument ot-yet-hardened sizing adding pipe line, steam or nitrogen are the most unstable in addition
Fixed, by time be there will be bias by action of gravity.In order to avoid gravity affects, existing cable production line all uses vertical standing
Formula production line.Wherein, producing high-pressure rubber sleeve cable three-layer co-extruded for 10-35KV needs the catenary suspension type continuous vulcanization production line of more than 20 meter high, raw
The twisted polyethylene cable producing 110-500KV needs the high tower production line of more than hundred meters.Obviously, the cost of both production lines
The most costly, it is generally required to several ten million or even the investment of several hundred million unit, up to more than 2 years construction period, and need boiler, system
Nitrogen equipment, energy consumption is the highest, and discharge capacity is big, seriously polluted, constrains the development that China's cable produces.
Summary of the invention
The problem high in order to solve existing cross-linking production line energy consumption, the present invention provides a kind of energy-saving three-layer co-extruded dry method to hand over
Connection cable production line, power consumption is few, saves the energy.
The present invention solves technical problem and be the technical scheme is that
Three-layer co-extruded cross-linking cable production line, is distributed on three platforms, this production line include three extruders, three layers altogether
Squeeze head, upper traction machine, lower traction machine, upper sealer, lower sealer and pipeline, three extruders, three-layer co-extruding machine head, on lead
Drawing machine and upper sealer is respectively positioned on three layers of platform, three extruders are all connected with three-layer co-extruding machine head, three-layer co-extruding machine head position
Between upper traction machine and upper sealer, lower sealer is connected with upper sealer by pipeline, lower sealer and lower traction seat in the plane
On one layer of platform；The driving means of described three extruders is made up of alternating-current variable frequency motor and converter, three extruders
The feeding section of screw rod and melt zone are double thread structure, and the heating control apparatus of described pipeline is by energy-economic transformer and PC program
Pid control module is constituted.
The invention has the beneficial effects as follows: energy-saving production line automation degree is high, efficiency is high；Energy-saving effect is notable, than biography
System device energy conservation 30%-40%.
Accompanying drawing explanation
Fig. 1 is the structural representation of three-layer co-extruded cross-linking cable production line of the present invention.
Detailed description of the invention
Below in conjunction with the accompanying drawings the present invention is described in further details.As it is shown in figure 1, the energy-saving co-extruded cross-linking of the present invention
Cable production line, is distributed on three platforms, this production line include three extruders 1, three-layer co-extruding machine head 2, upper traction machine 3,
Lower traction machine 4, upper sealer 8, lower sealer 9 and pipeline 10, three extruders 1, three-layer co-extruding machine head 2, upper traction machine 3 and on
Sealer 8 is respectively positioned on three layers of platform, and three extruders 1 are all connected with three-layer co-extruding machine head 2, and three-layer co-extruding machine head 2 is positioned at
Between traction machine 3 and upper sealer 8, lower sealer 9 is connected with upper sealer 8 by pipeline 10, lower sealer 9 and lower traction machine
4 are positioned on one layer of platform；The driving means of three extruders 1 is made up of alternating-current variable frequency motor and converter, three extruders 1
Feeding section 13 and the melt zone 12 of screw rod are double thread structure.
The pipeline heating of the present invention uses advanced in performance energy-economic transformer, uses PC programme-control, heats and be incubated two
Use different voltage under the state of kind, can meet and heat rapidly, the effect of heat preservation energy-saving.Pipeline heating is arranged particular by copper aluminum
Transformer short-circuit heating realizes, and under heated condition, controllable silicon turns on as 380V entirely, and under keeping warm mode, controllable silicon is partially ON is
260V.Generally line temperature is set as 300 DEG C, and heat time heating time is shorter, and temperature retention time length is a little；When heat, when protect
Temperature, length heat time heating time, temperature retention time length are controlled by PC program PID completely.Actual temperature is the most remote away from design temperature, during heating
Between the longest, temperature retention time is the shortest；Vice versa.Being incubated with aluminosilicate material outside bringing-up section pipeline, cooling section is not added with protecting
Adiabator.
