Detailed Description
The utility model provides an extruder temperature control system, for making the utility model discloses a purpose, technical scheme and effect are clearer, clear and definite, and it is right that the following refers to the attached drawing and the embodiment is lifted the utility model discloses further detailed description. It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the invention.
Example one
Referring to fig. 1-2, the utility model provides an extruder temperature control system, which comprises a plurality of heaters 1 sleeved on an extruding screw cylinder 3' of an extruder, a plurality of cooling water channels (not shown in the figure) respectively used for cooling heating areas of the heaters, a water inlet main pipe 2, a water outlet main pipe 3 and a control module; the extruding device also comprises an open type water collecting tank 4 arranged below the extruding screw cylinder 3' (namely, the upper side of the water collecting tank is an opening); the inlet of each cooling water channel is connected with the water inlet main pipe through a water inlet branch pipe 5, the outlet of each cooling water channel is connected with a water outlet branch pipe 6, the water outlet branch pipe is used for conveying cooling water to the water collecting tank, and the water outlet main pipe is connected with the bottom of the water collecting tank.
When the cooling water supply system works, after cooling water enters the cooling water channels from the water inlet branch pipes 5, the cooling water flows into the water collecting tank from the water outlet branch pipes 6, the water flows to the water outlet main pipe in the water collecting tank and is finally conveyed to the cooling water supply system again, the cooled water is sent to the extruder through the water inlet main pipe 2, and the circulation is carried out. Because the water catch bowl is open in this in-process, therefore water can the evaporation cooling carry out the primary cooling, can obtain abundant cooling when the water through the primary cooling cools off in cooling water supply system again to avoid because the cooling water cooling is insufficient and lead to the cooling effect poor to extruding the spiral shell section of thick bamboo.
In order to further improve the cooling effect, a fan may be provided above the water collection tank, and the air flow is accelerated by the fan, thereby taking more heat away.
Specifically, the control module includes a controller 7 (e.g., a PLC controller), a plurality of heater switches 8, and a plurality of solenoid valves 9; all the heater switches and the electromagnetic valves are electrically connected with the controller; each heater 1 is correspondingly provided with a heater switch 8, and each water inlet branch pipe 5 is provided with an electromagnetic valve 9. In the working process, the controller controls the heater to work by controlling the on-off of the heater switch and controls the flow of cooling water through the electromagnetic valve, so that the corresponding area is controlled within a required temperature range.
Further, the control module further comprises a plurality of temperature sensors 10, and all the temperature sensors are electrically connected with the controller 7; one temperature sensor 10 is provided for each heating region of the heater 1. The temperature sensor can adopt a thermocouple, the temperature sensor is used for measuring the temperature of each area in real time and feeding the temperature back to the controller, the controller controls the heater switch and the electromagnetic valve to work according to the actually measured temperature change condition, if the temperature is lower than the target temperature, the heater is started to heat, if the temperature is higher than the target temperature, the electromagnetic valve is opened to introduce cooling water to cool, and the temperature is constant to the target temperature.
Preferably, the main outlet pipe 3 is provided with a filter 11. Since the water collection tank is open, particles or other impurities in the air may fall into the water collection tank and enter the cooling water circulation process, eventually causing the pipe to be blocked, where they can be filtered out by a filter. Filters are known in the art and are available directly from the market, such as the STY series Y filters manufactured by waukee filtration technology limited.
