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, and they combine and constitute whole typing groove cooling water recirculation system.This typing groove cooling water recirculation system is subjected to 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.Therefore must be improved.
Summary of the invention
The purpose of this utility model is to be subject to variation of ambient temperature and to influence the technological parameter adjustment at existing extruder typing groove cooling water recirculation system, 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 extruder typing groove cooling water recirculation system of technological requirement, reach and just can be lower than the temperature of assurance recirculated water under the product technological parameter condition in control range under the prerequisite that does not increase energy input in addition at temperature.
The technical solution of the utility model is:
A kind of extruder typing groove cooling water recirculation system, comprise cooling water tank 1, cooling water pump 2, the input of cooling water pump 2 links to each other with cooling water tank 1, the output of cooling water pump 2 links to each other with the cooling water intake of typing groove mould 3, the water out of typing groove mould 3 links to each other with cistern 5 by return pipe 4, cistern 5 links to each other with cooling water tank 1 by 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, 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 beneficial effects of the utility model:
1, the utility model can satisfy the technological requirement of extruder with less investment to original circulatory system transformation, has small investment, and instant effect is transformed simple and conveniently, improves the advantage of existing extruder performance.It can not increase energy input in addition just can be lower than the temperature of assurance recirculated water under the product technological parameter condition in control range at temperature;
2, this practical new equipment has increased a function of extruder;
3, use less fund input to satisfy current production demand;
4, improve working condition, guarantee that product quality reaches customer requirement;
5, help reducing production costs, enhance productivity.
Description of drawings
Fig. 1 is a water circulation system structural representation of the present utility model.
Fig. 2 is the electric control schematic diagram of automatically controlled water valve of the present utility model.
The specific embodiment
Below in conjunction with drawings and Examples the utility model is further described.
As shown in Figure 1, 2.
A kind of extruder typing groove cooling water recirculation system, comprise cooling water tank 1, cooling water pump 2, the input of cooling water pump 2 links to each other with cooling water tank 1, the output of cooling water pump 2 links to each other with the cooling water intake of typing groove mould 3, the water out of typing groove mould 3 links to each other with cistern 5 by return pipe 4, cistern 5 links to each other with cooling water tank 1 by water inlet pipe 6, on water inlet pipe 6, water circulating pump is installed, between return pipe 4 and cooling water tank 1, be 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, 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 present utility model is:
When water temperature was lower than product requirement in the environment: automatically controlled water valve 8 is controlled closed automatically, the cooling water of extruder produces self-loopa, promptly the water out from typing groove mould 3 is back to cooling water tank 1 by circulating water pipe 7, under the effect of cooling water pump 2, enter typing groove mould 3, enter again in the circulating water pipe 7, and flow in the cistern 5 without return pipe 4, because the volume of equipment water tank is less, the temperature of recirculated water be heated rise very fast, when water temperature arrives product requirement, automatically controlled water valve 8 is controlled to be opened automatically, and the water of excess temperature flows into cisterns 5 through return pipe 4.Because backwater, at this moment the water level of cooling water tank 1 can descend, and when reaching down the water level controlled location, water intaking valve is opened automatically, mends the lower cold water of temperature to cooling water tank 1, when cold water and hot water reach uniform temperature through mixing, and automatically controlled water valve 8 controlled closing.At this moment because the water level of cooling water tank 1 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 8 is controlled by apparatus cools water tank 1 temperature: the temperature signal that is read cooling water tank 1 by thermocouple 12 is transported to temp controlled meter 11, through comparing, result is relatively outputed to the electromagnet coil of automatically controlled water valve 8 by solid-state relay 9 with setting value.Water intaking valve is subjected to the water level control (equipment original function) of cooling water tank 1.
It is all same as the prior art that the utility model does not relate to part.
