The twin-screw extruder comprises a cooling assembly which comprises a heat exchanger, a conveying water pump, a cooling system and a purification system, wherein the heat exchanger comprises a water inlet main pipe and a water outlet main pipe; the cooling system and the purification system are intercommunicated; the water outlet main pipe is connected with the cooling system, and the water inlet main pipe is connected with the purification system; the conveying water pump is arranged on the water inlet main pipe and/or the water outlet main pipe; since the cooling assembly comprises a heat exchanger and the heat exchanger can be used for absorbing heat through the heat exchange effect, the twin-screw extruder is cooled; a cooling tower adopted by the cooling system can be used for cooling the cooling water heated up due to heat absorption; and the purification system can be used for intercepting and filtering adsorbing impurities when water flows through the purification system, so that the cooling water is purified. The twin-screw extruder provided by the utility model can be used for effectively reducing the temperature of the cooling water, and meanwhile, the twin-screw extruder is provided with the purification system which can be used for filtering the cooling water, thus the problem that polluted cooling water easily blocks water pipes is solved.
Description
Technical field
The utility model relates to a kind of double screw extruder.
Background technology
For guaranteeing double screw extruder temperature stability in process, most of double screw extruders adopt water circulation cooling, the demand that the water circulation system guarantee of appropriate design is produced.
Double screw extruder in the market adopts the cooling of unit closed circulation, be limited by the restriction of double screw extruder self design, adopt this endless form can cause recirculated water following problems to occur: 1). cooling water temperature is too high, and cooling-down effect is bad, the water waste of volatilizing in a large number; 2). cooling water uses for a long time and can produce impurity and greasy dirt, causes the recirculated water water pipe to stop up, and influences the stability of device temperature; 3) cooling of unit platform recirculated water can cause the energy consumption height.
Head office is described, how to solve the problem that cooling water pollution stops up water pipe easily, becomes those skilled in the art's problem demanding prompt solution.
