Heat treatment device for plastic odor removal

Abstract

The invention discloses a heat treatment device for plastic deodorization. The heat treatment device comprises a tank body, a spiral guide plate, a central pipe, a heater, a vacuumizing mechanism and a driving mechanism, a spiral material lifting channel is formed between the spiral material guide plate and the inner wall of the tank body; the plastic particle feeding device has the beneficial effects that the driving mechanism drives the tank body to rotate along the axis of the tank body, so that plastic particles in the tank body spirally ascend upwards along the material lifting channel, and after reaching the upper end of the material lifting channel, the plastic particles enter the upper end of the central pipe, and under the action of gravity, the plastic particles are conveyed to the upper end of the central pipe. And the plastic particles enter the lower end of the material lifting channel from the lower end of the central pipe and then continue to ascend along the material lifting channel, the process is repeated, in the process, the heater heats the plastic particles, and the vacuumizing mechanism enables a negative pressure environment to be formed in the tank body, so that VOC gas is continuously released on the surfaces of the plastic particles and is pumped away and discharged through the vacuumizing mechanism. Therefore, the plastic particles can be efficiently deodorized through the device, and the energy consumption can be reduced.

Description

technical field [0001] The invention relates to the technical field of plastic processing, in particular to a heat treatment device for deodorizing plastic. Background technique [0002] As one of the most common materials in people's daily life, plastic has been used in all aspects of life. Among them, for the use in the fields of automobile interior decoration and some packaging materials, the requirements for the odor level of plastic raw materials are put forward to reduce the harm of volatile gases of plastic products produced from such plastics to the human body. [0003] The odor of plastic raw materials usually comes from VOC (volatile organic compounds). By heating the plastic raw materials to a certain temperature, the volatilization of odorous substances in the plastic particles can be accelerated, so that the plastic raw materials are produced and processed into plastic products. VOC gas is greatly reduced Volatilization, reduce the odor level of the produced pl...
