Waste heat recycling and baking device of energy-saving environment-friendly injection machine

Abstract

The invention relates to a waste heat recycling and baking device of an energy-saving environment-friendly injection machine. The device comprises a temperature control box, a baking barrel, a filter, a wind pump, an injection machine gun barrel, a heat collection device, and a remote controller; the baking barrel, filter, and wind pump are connected through a gas transmission pipeline, the temperature control box is arranged on the right side of the baking barrel, the injection machine gun barrel is sleevedly connected to the heat collection device, and the remote controller cooperates with the temperature control box. The provided device has a simple structure, the removable operation can be achieved through the cooperation between the sensor and the remote controller, when the device is on, an operator can operate the device without going near to the device, and thus the device is very safe. Moreover, the heat collection device is sleevedly connected to the injection machine gun barrel, thus the waste heat in the injection machine gun barrel can be converted into thermal energy that can be applied to the baking barrel to dry the plastic, and the waste heat efficient utilization is realized. The device is also provided with a filter to remove the dusts from the baking barrel so as to prevent the gas transmission pipeline from being obstructed, and the normal operation is guaranteed.

Description

technical field [0001] The invention relates to the technical field of heat source recovery and utilization devices, in particular to an energy-saving and environment-friendly waste heat recovery drying device for injection molding machines. Background technique [0002] In the production process of the injection molding machine, after the plastic raw material enters the drying barrel to dry, the heating ring arranged on the screw barrel heats and melts the plastic raw material, and the screw pushes it to the mold for injection molding. Traditional dryers use high-power electric heating tubes, and use a blower to blow the hot air into the barrel for drying. Electric energy becomes heat energy, which consumes a lot of energy. At the same time, after the hot air passes through the drying barrel, a certain amount of heat remains The upper mouth of the material barrel is lost. In addition, the heating ring of the barrel is basically exposed, and the heat energy is directly dissi...

Problems solved by technology

However, the starting end of the second heat collection circuit is connected to the upper opening of the drying barrel of the injection molding machine through a fork, which will cause the dust from the drying barrel to enter the drying barrel through the air pump, which will cause the drying barrel to block for a long time. In addition, the operation interface of the device is all set on the body, which cannot realize the mobile operation of the staff, which is very troublesome and wastes time
