Background technology
Plastic pipe range of application is very wide, and application is at present mainly supplies water and supplies natural gas.The pipeline comprising urban pipe network is all mainly plastic cement pipeline, and national annual plastic cement pipeline output is very large.
The industrialization line flow procedure of plastic pipe is as follows.A plastic cement material is carried out preheating in raw material cabin, and its preheat temperature about 80 degree, in order to discharge the moisture content may carried secretly in plastic grains.Raw material cabin adopts electrical heating, and arranges electrical heating wire on raw material bulkhead.Because the plastic material needed for different production lines is different, or the output of scheduling of production is different, so general plastic pipe pipeline production line has the raw material cabin of various different capabilities.
Plastic grains after preheating puts into mould, and by applied at elevated temperature, it dissolves, and extrudes core continuously by screw rod, and plastic pipe is shaped.Plastic pipe after shaping enters into immediately in vacuum tank and carries out cold water spray, lowers the temperature to plastic pipe surface.Reducing temperature twice is carried out through cooler bin again after cooling.Plastic pipe after repeatedly lowering the temperature cuts off at the tail end of production line, rolls off the production line.
On plastic pipe production line, a plastics material is made to have plasticity mainly through high temperature, then at high temperature just plastic by extruding.The extrusion die temperature of general plastic cement pipeline is 180 degree to 200 degree, and this means that the plastic pipe temperature squeezed out in core is not less than 180 degree, the central temperature of plastic pipe reaches 200 degree.So plastic tube product line itself has a large amount of waste heats to utilize.And now, these waste heats are all taken away by circulating water, do not utilized.Heat dissipation in a large amount of plastic pipes, forms thermal waste, affects environment simultaneously.

Accompanying drawing explanation
Fig. 1 is the utility model structural representation.
Detailed description of the invention
The utility model offers heat recovery hole on core 12, and heat recovery hole is directly connected to core inside, and after opening negative-pressure air fan 9, the waste heat in core is discharged from inside, enters in heat recovery pipe 11.By the temperature detected in core real during the first temperature-detecting device 10, too high or too low for temperature in core, or in core, temperature fluctuation range is too large, does not utilize the production of plastic pipe.Temperature value in detected core returns and is fed to master control borad by the first temperature-detecting device, master control borad regulates the running parameter of negative-pressure air fan according to temperature in current core, that is: when temperature in core is too high, then open large negative-pressure air fan air output with the more heats of sucking-off, otherwise then turn down.
What load in raw material preheating storehouse is plastic grains, and the effect in raw material preheating storehouse mainly preheats the plastic grains entering core, and is discharged the moisture content comprised in plastic grains by heating.The preheat temperature of plastic grains can not be too high, certainly can not be too low, its draining too low and pre-heat effect not good, affect finished product quality; The too high plastic rubber material particle that can use of preheat temperature dissolves, and lumps in raw material cabin.Generally control, below 80 degree, to be not less than 70 degree to the preheat temperature of plastic grains.
The utility model adopts air-heater to control to send into the hot blast air quantity in raw material preheating storehouse, and adopts air-cooler to be mixed into cold wind, regulates the gas flow temperature finally entered in storehouse, makes the temperature entered in raw material preheating storehouse meet 70 ~ 80 DEG C of degree interval.Be specially: production line has multiple raw material preheating storehouse, according to scheduling of production, enable different raw material preheating storehouses, when this raw material preheating storehouse is enabled in plan, namely to the air-heater 8 started corresponding to this raw material preheating storehouse, hot blast is imported from heat recovery pipe, the real hot blast temperature value detecting importing during the second temperature-detecting device 5, when detecting that imported temperature value is too high, master control borad turns down air-heater air output, and corresponding open cold blower fan 6 is mixed into cold wind, the import volume of configuration hot blast and cold wind, until the temperature detected by the second temperature-detecting device reaches required temperature.When the hot blast temperature sent into is too low, directly close air-cooler, strengthen the hot blast import volume of air-heater.Cooling gas check valve prevents the hot blast imported from the inside and outside row of cold wind arm 7.
Charge level measurer is provided with the upper, middle and lower each position of raw material preheating storehouse inwall, and acoustic-optic alarm is arranged on raw material cabin full position.
Status displays can be display floater, also can show for indicator lamp.
