Abstract
The present invention relates to blade extruder charging aperture cooling means and device, described method is that the charging spacer shell of tool path and condenser are connected to form enclosure space, at the in-built low gasification point liquid of the path of charging spacer shell, heat is taken out of when becoming steam mutually by liquid heat absorption, then transfers heat to material in hopper by condenser and fluidized flow realizes charging aperture circulating cooling back in material spacer shell passage in condenser.Cooling device comprises charging spacer shell, condenser and connects condenser pipe and the hopper of spacer shell and condenser.In the present invention, gas medium is entered in condenser by the condenser pipe be connected with charging spacer shell top and also liquefies within the condenser as liquid, and liquid flows back in charging spacer shell by condenser pipe, thus realizes circulating cooling.This higher than the thermaltransmission mode heat flow density of conventional contracurrent system with latent heat of vaporization mode transferring heat, the heat of simultaneously vaporizing obtains and recycles, and has the features such as good effect of heat exchange, energy consumption be low.
Description
Technical field
The present invention relates to a kind of energy-conservation cooling technical field of high polymer material plasticizing conveying equipment charging aperture, be specifically related to blade extruder charging aperture cooling means and device.
Technical background
Blade extruder is that a kind of tensile deformation controls and has the polymer material molding process equipment of positive conveyance characteristic, and plastifying extrusion equipment difference with conventional screw is blade extruder just preliminary consolidation, exhaust in flight blade unit I.For effectively controlling the stability and the raising exhaust performance that plastify transport process, effective cooling is implemented to the charging aperture of extruder extremely important.
The cooling means mainly air-cooled and water-cooled of charging aperture.Air-cooledly usually need to arrange certain passage recycling air blast in barrel or cooling cover and blow air and cool, the general volume of air cooling system is comparatively large, and cooling velocity is slower; Water-cooled utilizes logical recirculated water exactly, utilizes the flowing of water to be taken away by heat thus realizes cooling.Relatively air-cooled, water-cooled has that cooling velocity is fast, cooling device volume is little, low cost and other advantages, but easily causes and easily occur the phenomenon such as fouling, corrosion in chilling, water pipe and reduce cooling effect.
Air-cooled or the flowing of water-cooling system medium all needs additionaling power such as blower fan or water pump, and simultaneously the pressure of cooling effectiveness and medium and flow rate have very large relation.Heat exchange energy regenerating out utilizes difficulty in addition, and substantially waste, capacity usage ratio is low.
Summary of the invention
The object of the invention is to solve the problem that polymer material molding equipment charging aperture cooling effectiveness is low, energy dissipation is high, blade extruder charging aperture cooling means and device are provided.The present invention utilizes low gasification point material evaporation endothermic, condensation heat release to realize heat transmission, transfers heat to by condenser the object that material reaches preheating material while cooling charging aperture.
Blade extruder charging aperture cooling means, the charging spacer shell of tool path is connected to form into enclosure space with condenser by it, at the in-built low gasification point liquid of the path of charging spacer shell, heat is taken out of when becoming steam mutually by liquid heat absorption, then transfers heat to material in hopper by condenser and fluidized flow realizes charging aperture circulating cooling back in material spacer shell passage in condenser.
Realize the device of above-mentioned cooling means, comprise condenser, charging spacer shell, condenser pipe and hopper, the gas vent of charging spacer shell is connected with one end of condenser by condenser pipe, the liquid inlet of charging spacer shell is connected with the other end of condenser by condenser pipe, condenser is arranged in hopper, and material is between hopper and condenser.
Further, be provided with path in described charging spacer shell, path communicates with described gas vent and liquid inlet.
Further, low gasification point liquid is housed in described path.
The present invention is compared with existing cooling means and device, and tool has the following advantages:
1, higher than the thermaltransmission mode heat flow density of conventional contracurrent system with latent heat of vaporization mode transferring heat, good effect of heat exchange;
2, because heat is transmitted by saturated vapor, under the minimum temperature difference, there is high heat-transfer capability, close to constant temperature process;
3, the flowing of cooling procedure medium does not need external power, and energy consumption is low;
4, heat obtains and recycles, and improves the utilization rate of energy, good energy-conserving effect.
Accompanying drawing explanation
Fig. 1 cooling device for feed inlet structural representation;
Fig. 2 is the blade extruder structural representation with cooling charging aperture.
Detailed description of the invention
Below in conjunction with drawings and Examples, the present invention is described further, but the scope of protection of present invention is not limited to the scope of embodiment statement.
embodiment 1
With reference to figure 1, Fig. 2, constitute blade extruder by the blade feed unit I of the part compositions such as armature spindle 1, stator positioning sleeve 2, charging stator 3 baffle plate 4 and multiple blade are plastified sending unit II overlapped in series.As shown in Figure 1, the cooling device for feed inlet of this extruder forms primarily of the charging spacer shell 5 be arranged on charging stator 3, condenser pipe 6 and condenser 7.Charging spacer shell 5 is fixedly connected with the charging stator 3 in blade feed unit I, and charging spacer shell 5 inside is provided with path, and path is built with low gasification point material (as benzophenone).Charging spacer shell 5 to be connected with the condenser 7 with bigger serface by condenser pipe 6 and to form the space closed.The gas vent of charging spacer shell 5 is connected with one end of condenser 7 by condenser pipe 6, and the liquid inlet of charging spacer shell 5 is connected with the other end of condenser 7 by condenser pipe 6, and condenser 7 is arranged in hopper 8, and material is between hopper 8 and condenser 7.
When inlet temperature raises, the liquid endothermic gasification in charging spacer shell 5 passage is gas, under the effect of gas and fluid density difference, enter into condenser 7 by condenser pipe 6.Liquid is liquefied as under the cooling effect of medium macromolecular material in condenser 7 and condenser 7 and hopper 8 of gaseous state, liquid flows back in the path of charging aperture coolant jacket 5 by condenser pipe 6, make the temperature of charging spacer shell 5 remain the boiling point of low gasification point, realize the cooling to charging aperture.Because cooling procedure has been come by the phase transformation of medium and do not need additionaling power, the heat simultaneously exchanged in cooling procedure is absorbed by the material in hopper, thus achieves the cooling energy-efficient to charging aperture.
