Abstract
The invention relates to an extruding machine, in particular to the extruding machine with double flow passages machine cylinder heating and cooling devices. Two strips of double flow passages that are not communicated with each other are processed at the interior of the machine cylinder and respectively relate to a heating flow passage and a cooling flow passage; two ends of each flow passage are respectively an oil inlet and an oil outlet. The invention changes the traditional thermal balance principle from another view; the heating and the cooling are finished by heat transfer oil; the heating oil and the cooling oil are carriers for thermal balance; the machine barrels of the double flow passages are main bodies for the heating oil and the cooling oil to carry out heat exchange. The two flow passages are not communicated with each other, only the reciprocating flow is carried out along the axial direction in parallel; therefore, the machine can run normally when the machine cylinder is ensured to be controlled under the required temperature.
Description
One, technical field
The present invention relates to a kind of twin-screw plastic extruder, particularly barrel heating cooling device.
Two, background technology
Generally, the machine barrel of twin-screw plastic extruder is to rely on heater and cooling water to heat the cooling exchange, both machine barrel external heat, the cooling of machine barrel internal water, to guarantee extruder barrel and the on-stream thermal balance of screw rod, this method is widely used in the extruder field, in application, find, the thermal inertia of this method and cold inertia all are very large, and the control temperature fluctuation is big, and consumes energy is bigger.
Three, summary of the invention
The objective of the invention is to overcome above-mentioned not enough problem, a kind of extruder double passage barrel heating cooling device is provided, stable temperature control is even, and hot cold inertia is little, the energy resource consumption less wastage.
The technical scheme that the present invention is adopted for achieving the above object is: extruder double passage barrel heating cooling device, process two dual channels that do not connect mutually in machine barrel inside, be respectively and add hot flow path and coolant flow channel, each runner two ends is respectively oil-in and oil-out.
Adding during described heating flows in the hot flow path adds deep fat, and coolant flow channel flows and adds deep fat, and the oil mass that adds hot flow path during cooling reduces, and the oil mass of coolant flow channel increases.
Described hot flow path and the reciprocal vertically runner of coolant flow channel of adding.
Described runner oil-in and oil-out are communicated with the oil station by pipeline, and control valve and control device are housed on the pipeline, by temperature signal, change proportioning valve aperture in the oil system, regulate the ratio of cold and hot oil turnover.
The present invention compares with existing like product has outstanding feature: it is from having changed traditional heat balance mechanism in essence, heating and cooling, all be to finish with conduction oil, heating and cooling oil is thermally equilibrated carrier, double passage barrel is exactly to add the main body that deep fat and cold oil carry out heat exchange, does not connect mutually between this dual channel, just back and forth flows vertically side by side, guarantee that machine barrel is controlled under the temperature that needs, machine can move normally.When the temperature of machine is lower than the temperature of setting, add hot flow path in heating, coolant flow channel is also in heating, improved the efficient of heating greatly, when the temperature of machine was higher than the temperature of setting, the oil mass that adds hot flow path reduced, the oil mass of coolant flow channel increases, make temperature reduce to the temperature that sets rapidly, whole system will be gone round and begun again like this and be got into smooth, and finishes the process of automatic control.The experiment proved that and use double passage barrel heating cooling device of the present invention, by with the coupling of control device, the temperature signal input control device changes proportioning valve aperture in the oil system, regulate the ratio of cold and hot oil turnover, the temperature of control machine barrel has reduced thermal inertia and cold inertia that rising and reduction owing to temperature produce, and stable temperature control is even, reduce temperature fluctuation, reduced a large amount of energy resource consumptions.

Five, the specific embodiment
As Fig. 1,2, extruder double passage barrel heating cooling device shown in 3, the machine barrel two ends are flanged ends 38, process two dual channels that do not connect mutually in machine barrel 37 inside, be respectively and add hot flow path and coolant flow channel, add hot flow path and coolant flow channel and be vertically reciprocal runner, each runner two ends is respectively oil-in and oil-out, as shown in figs. 1 and 3, adding hot flow path is that hot oil inlet 39 is communicated with runner 3 successively, 4,7,8,11,12,15,16,19,20,23,24,27,28,31,32,35,36, runner 36 is communicated with hot oil outlet 42, coolant flow channel is that cold oil import 40 is communicated with runner 1 successively, 2,5,6,9,10,13,14,17,18,21,22,25,26,29,30,33,34, runner 34 is communicated with cold oil outlet 41, adding during heating flows in the hot flow path adds deep fat, coolant flow channel flows and adds deep fat, the oil mass that adds hot flow path during cooling reduces, and the oil mass of coolant flow channel increases.Add as shown in Figure 4 during application the oil-in of hot flow path and coolant flow channel and oil-out respectively by pipeline with add deep fat station 43 accordingly and the cold oil station is communicated with, oil mass ratio adjusting valve 44 and control device are housed on the pipeline, pass through temperature signal, change ratio adjusting valve aperture in the oil system, regulate the ratio of cold and hot oil turnover.Behind the test pressure, startup adds deep fat, cold oil station, sets the technological temperature that needs, and machine will be controlled the technological temperature that sets automatically.
