Description

Technical Field

[0001] The utility model belongs to the technical field of drying and cooling, and in particular relates to a drying and cooling mechanism of a twin-screw granulator. Background Art

[0002] Twin-screw granulator is mainly used for filling, blending, modification, addition, chlorination, processing of polypropylene and super absorbent resin of rubber and plastic and engineering resin.

[0003] During the granulation process of the existing twin-screw granulator, the granulated raw materials easily absorb moisture in the air and become damp. The performance of plastic products made from damp raw materials is significantly reduced compared to that made from dry raw materials, which is not conducive to the production of high-quality plastic products and affects the benefits of the enterprise. Therefore, a drying and cooling mechanism of a twin-screw granulator is needed to solve the above problem. Utility Model Content

[0004] The utility model aims to provide a drying and cooling mechanism for a twin-screw granulator to solve the problems raised in the above-mentioned background technology.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a drying and cooling mechanism of a twin-screw granulator comprises a machine platform, a twin-screw head granulator body is fixedly arranged on the machine platform, a feed pipe is connected to the twin-screw head granulator body, a discharge pipe is connected to the feed pipe, a fixed column is fixedly connected to one side of the machine platform, a drying fan is fixedly connected to the top of the fixed column, an air outlet of the drying fan is connected to a drying air duct, a limited rotation disc is provided inside the discharge pipe, a motor is provided at the rotation part on the back of the limited rotation disc, a connecting pipe is connected to one side of the discharge pipe, a section of the connecting pipe is connected to a cooling machine frame, a cooling circulation pipe is provided inside the cooling machine frame, a cooling pelletizer body is provided on the twin-screw head granulator body, one end of the connecting pipe is connected to the cooling pelletizer body, and a control body is fixedly arranged on the machine platform.

[0006] By setting up a discharge pipe, when the raw material enters the discharge pipe, it will first fall on the limit turntable, and then the drying fan will be started to dry the raw material in the discharge pipe through the drying air duct. During this period, since the material can be temporarily stored on the limit turntable, the material can be fully dried by wind. After drying for a certain period of time, the motor will start, and the motor will drive the limit turntable to rotate, so that the material on the limit turntable will fall into the twin-screw head granulator body through the feed pipe for processing. During this period, the raw material is dried, which helps to ensure the quality of the final plastic product produced by the granulator. In addition, in the process of hot air drying in the discharge pipe by the drying air duct, part of the wind force will enter the connecting pipe. When these winds pass through the cooling frame, they will be cooled and finally discharged into the cooling granulator body, and the extruded material will be cooled by the way, so as to facilitate faster discharge.

[0007] As a preferred embodiment, a first filter window is provided at the connection point between the drying air duct and the feeding pipe.

[0008] As a preferred implementation, the limiting turntable is circular and has a weighing function.

[0009] Through the weighing function of the limit turntable, under the control of the control body, the incoming material can be conveniently weighed, which helps to achieve accurate material discharge and also controls the drying amount.

[0010] As a preferred embodiment, a fixing block is fixedly connected to the back side of the discharge pipe, and the motor is fixedly connected to the fixing block.

[0011] As a preferred embodiment, a feeding port is provided on the lower surface of the cooling pelletizer body.

[0012] As a preferred embodiment, a second filter window is provided at the connection point between the connecting pipe and the feeding pipe.

[0013] By providing the first filter window and the second filter window, materials can be prevented from falling into the drying air duct and the connecting pipe to cause pipe blockage.

[0014] Compared with the prior art, the beneficial effects of the utility model are:

[0015] The utility model provides a feeding pipe. When the raw material enters the feeding pipe, it will first fall on the limit turntable. Then the drying fan is started and the raw material in the feeding pipe is dried through the drying duct. During this period, the material can be temporarily stored on the limit turntable, so that the material can be fully dried by wind. After drying for a certain period of time, the motor will start, and the motor will drive the limit turntable to rotate, so that the material on the limit turntable will fall into the twin-screw head granulator body through the feeding pipe for processing. During this period, the raw material is dried, which helps to ensure the quality of the final plastic product produced by the granulator. In addition, in the process of hot air drying in the feeding pipe by the drying duct, a part of the wind force will enter the connecting pipe. When the wind passes through the cooling frame, it will be cooled and finally discharged into the cooling granulator body, and the extruded material will be cooled by the way, so as to facilitate faster feeding.

[0016] The utility model, through the weighing function of the limit turntable, can conveniently weigh the incoming material under the control of the control body, which helps to achieve accurate material unloading and also controls the drying amount. In addition, by arranging the first filter window and the second filter window, it can prevent the material from falling into the drying air duct and the connecting pipe to cause pipeline blockage.
