Problems solved by technology

Existing cooling water tanks generally recycle water. As the use time increases, the water temperature rises, and the flow rate of the cooling water remains basically unchanged, which will affect the cooling effect and deteriorate the product quality. An automatic controllable cooling water temperature is needed. cooling water tank

Abstract

The invention relates to a cooling water channel of a double-screw extruder. The cooling water channel of the double-screw extruder comprises a water channel body and a water storage tank; a temperature sensor is arranged at the bottom in the water channel body and connected with a controller; a water flow baffle is further arranged at the bottom in the water channel body; a water inlet of the water channel body is connected with a water inlet pipe; the other end of the water inlet pipe communicates with the bottom of the water storage tank; the water inlet pipe is provided with a variable-frequency water pump which is connected with the controller; a water outlet of the water channel body is connected with a water outlet pipe; the other end of the water outlet pipe communicates with the top of the water storage tank; the water outlet pipe is provided with a cooler; and a filter screen is arranged on the upper portion in the water storage tank. According to the cooling water channel of the double-screw extruder, cyclic utilization of cooling water is achieved by arranging the water storage tank; by arranging the temperature sensor, the controller and the variable-frequency water pump, the temperature of the cooling water in the water channel body is automatically controlled; the cooling water can be in full convection in the water channel body by arranging the water flow baffle; and plastic is pressed below the liquid level of cooling liquid by arranging a supporting guiding wheel and a pressing rod, and the cooling effect is improved.

Description

technical field [0001] The invention relates to a cooling water tank, in particular to a cooling water tank for a twin-screw extruder. Background technique [0002] The extruded plastic layer extruded by the twin-screw extruder should be cooled and shaped immediately after leaving the machine head, otherwise it will be deformed under the action of gravity. The cooling method usually adopts water cooling. Existing cooling water tanks generally recycle water. As the use time increases, the water temperature rises, and the flow rate of the cooling water remains basically unchanged, which will affect the cooling effect and deteriorate the product quality. An automatic controllable cooling water temperature is needed. cooling tank. Contents of the invention [0003] What the present invention is intended to provide is a cooling water tank for a twin-screw extruder. [0004] In order to solve the above technical problems, the present invention provides the following technical...
