Abstract
The heat preservation mechanism of extruder, on the electric heating cover on screw channel surface, interval arranges some insulation shells, and the built-in rock wool of insulation shell, before and after each insulation shell, both sides arrange air inlet and air outlet respectively, and air inlet is connected with blower fan.The utility model by arranging insulation on electric heating cover, insulation is simultaneously outside to be connected with blower fan, has both avoided scattering and disappearing of electric heating cover heat, in turn ensure that the temperature stabilization in screw channel, substantially increase the utilization rate of electric energy, there is the advantage that structure is simple and easy to use.
Description
Technical field
The utility model relates to plastics forming equipment technical field, is specifically related to a kind of heat preservation mechanism of extruder.
Background technology
Extruder, main frame is extruding machine, it is made up of extrusion system, transmission system and heating system, its heating system is primarily of the electric heating cover composition being arranged on screw channel surface, the electric heating cover surface of existing extruder does not arrange any lagging facility, cause the heat changed by electric energy in a large number to scatter and disappear in vain in air like this, cause the waste of a large amount of electric energy, cause processing cost to remain high.
Summary of the invention
The utility model provides a kind of heat preservation mechanism of extruder, and the extruder existed to solve prior art does not have heat preservation mechanism to cause heat waste to increase the problem of processing cost.
The utility model solves the technical scheme that its technical problem adopts:
A heat preservation mechanism for extruder, on the electric heating cover on screw channel surface, interval arranges some insulation shells, and the built-in rock wool of insulation shell, before and after each insulation shell, both sides arrange air inlet and air outlet respectively, and air inlet is connected with blower fan.
The operation principle of heat preservation mechanism of the present utility model is: during extruder work, the heat that electric heating cover distributes is by the rock wool of insulation shell and extraneous air is isolated comes, in order to the temperature in screw channel is remained within the scope of set point of temperature, prevent overtemperature, each insulation shell is connected with a Fans, cooling-air enters from air inlet and blows out from the air outlet of opposite side, lowers the temperature to insulation shell, keeps the stable of temperature.
The utility model by arranging insulation on electric heating cover, insulation is simultaneously outside to be connected with blower fan, has both avoided scattering and disappearing of electric heating cover heat, in turn ensure that the temperature stabilization in screw channel, substantially increase the utilization rate of electric energy, there is the advantage that structure is simple and easy to use.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is further illustrated.
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the structural representation in A-A cross section in Fig. 1.
1 insulation shell, 2 air inlets, 3 air outlets, 4 blower fans, 5 electric heating covers, 6 screw channel, 7 rock wools in figure.
Detailed description of the invention
As depicted in figs. 1 and 2, a heat preservation mechanism for extruder, on the electric heating cover 5 on screw channel 6 surface, interval arranges some insulation shells 1, the built-in rock wool 7 of insulation shell 1, before and after each insulation shell 1, both sides arrange air inlet 2 and air outlet 3 respectively, and air inlet 2 is connected with blower fan 4.
The operation principle of heat preservation mechanism of the present utility model is: during extruder work, the heat that electric heating cover 5 distributes is come with extraneous air is isolated by the rock wool 7 of insulation shell 1, in order to the temperature in screw channel 6 is remained within the scope of set point of temperature, prevent overtemperature, each insulation shell 1 is connected with a Fans 4, cooling-air enters from air inlet 2 and blows out from the air outlet 3 of opposite side, lowers the temperature to insulation shell 1, keeps the stable of temperature.
