Description
Technical field
The utility model relates to the cooling device of using on a kind of extruder.
Background technology
Existing extruder typing groove cooling water recirculation system by: water inlet pipe-cooling water tank-water pump-typing groove mould cooling-return pipe-cistern-water pump-water inlet pipe is formed; Wherein first, five is the water inlet pipe and water outlet pipe of extrusion equipment; Second and third, four be that extrusion equipment inside provides for cooling die; Several of back are the auxiliary equipment beyond the extrusion equipment, the whole typing groove of the formation that they combine cooling water recirculation system.This typing groove cooling water recirculation system receives ambient temperature effect big rise and fall throughout the year, from the several years to 30 several years, because range of temperature has a strong impact on the quality of production more greatly.Particularly environment temperature is lower than 15 when spending, and the production technology adjusting range of product is just very narrow, dimension overproof often occurs, causes product rejection.
The utility model content
The purpose of the utility model is subject to variation of ambient temperature and influences the technological parameter adjustment to existing extruder typing groove cooling water recirculation system exactly; And then influence the problem of extruded product quality; Design and a kind ofly can utilize the mould waste heat to adjust the cooling water tank temperature voluntarily according to environment temperature; Make it to satisfy the cooling device of using on the extruder of technological requirement, reach under the prerequisite that does not increase energy input in addition just can temperature be lower than under the product technological parameter condition guarantee recirculated water temperature in control range.
The purpose of the utility model can realize through following scheme:
The cooling device of using on a kind of extruder comprises cooling water tank, cooling water pump; The input of cooling water pump links to each other with cooling water tank, and the output of cooling water pump links to each other with the cooling water intake of typing groove mould, and the water out of typing groove mould links to each other with cistern through return pipe; Cistern links to each other with cooling water tank through water inlet pipe; Water circulating pump is installed on water inlet pipe, it is characterized in that between return pipe and cooling water tank, being provided with circulating water pipe, automatically controlled water valve is installed on the return pipe between circulating water pipe and the cistern; The coil of automatically controlled water valve links to each other with solid-state relay; Solid-state relay links to each other with temp controlled meter, and the control end of temp controlled meter links to each other with thermocouple, and thermocouple is installed in the cooling water tank.
The utility model helps reducing production costs, improve production efficiency and product quality.

The specific embodiment
Map 1, shown in Figure 2.The cooling device of using on a kind of extruder comprises cooling water tank 1, cooling water pump 2; The input of cooling water pump 2 links to each other with cooling water tank 1, and the output of cooling water pump 2 links to each other with the cooling water intake of typing groove mould 3, and the water out of typing groove mould 3 links to each other with cistern 5 through return pipe 4; Cistern 5 links to each other with cooling water tank 1 through water inlet pipe 6; On water inlet pipe 6, water circulating pump is installed, it is characterized in that between return pipe 4 and cooling water tank 1, being provided with circulating water pipe 7, automatically controlled water valve 8 is installed on the return pipe 4 between circulating water pipe 7 and the cistern 5; The coil of automatically controlled water valve 8 links to each other with solid-state relay 9; Solid-state relay 9 links to each other with temp controlled meter 11, and the control end of temp controlled meter 11 links to each other with thermocouple 12, and thermocouple 12 is installed in the cooling water tank 1.
The course of work of the utility model is:
When water temperature was lower than product requirement in the environment: automatically controlled water valve is controlled closed automatically, and the cooling water of extruder produces self-loopa, and promptly the water out from the typing groove mould is back to cooling water tank through circulating water pipe; Under the effect of cooling water pump, get into the typing groove mould; Get in the circulating water pipe again, and flow in the cistern, because the volume of equipment water tank is less without return pipe; The temperature of recirculated water be heated rise very fast; When water temperature arrived product requirement, automatically controlled water valve is controlled to be opened automatically, and the water of excess temperature flows into cistern through return pipe.Because backwater, at this moment the water level of cooling water tank can descend, and when reaching the water level controlled location, water intaking valve is opened automatically, mends into the lower cold water of temperature to cooling water tank, and cold water and hot water are when mix reaches uniform temperature, and automatically controlled water valve is controlled closes.At this moment because the water level of cooling water tank does not also reach water level, supplementing water also will continue to replenish, and when having only water level to reach water level, water intaking valve is controlled closing.In the whole circulation process; Automatically controlled water valve is controlled by the apparatus cools water tank temperature: the temperature signal that is read cooling water tank by thermocouple is transported to temp controlled meter; Through comparing, result is relatively outputed to the electromagnet coil of automatically controlled water valve through solid-state relay with setting value.Water intaking valve is controlled by the water level of cooling water tank.
