Embodiment Construction

[0037] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the present invention. Obviously, the described embodiments are the Some embodiments of the invention are not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

[0038] The technological process that the present invention adopts is as figure 1shown. The first step is concentrated feeding, that is, adding thermosetting plastic waste to the rotary heating furnace 3 until the set amount is added and then the feeding is stopped. The second step is high-temperature aerobic calcination, that is, high-temperature aerobic heating is...

Abstract

The invention provides a filler recovery device for thermosetting plastic waste and a recovery method. The filler recovery device mainly comprises a feeder, a feeder translation device, a rotary heating furnace, a spiral feeder, a cooling spray furnace, a dust filter, a tail gas purification furnace, a VOC detection device, a hydraulic lifting mechanism, a water cooling system, an air input system, a nitrogen input system, an electrical control system and the like. Organic matter in the thermosetting plastic waste is removed through a long-time high-temperature aerobic combustion method, filler in waste is recycled and can be reused for production of thermosetting plastic, cyclic utilization of the waste is achieved, and therefore the production cost is reduced, environmental pollution is reduced, and economic benefits are improved; and moreover, the production process of centralized feeding, high-temperature aerobic calcining, inclined discharging, continuous spraying cooling and continuous discharging is adopted, the device is compact in structure and high in production efficiency, and continuous batch production can be achieved.

Description

technical field [0001] The invention belongs to the technical field of material recycling, and in particular relates to a filler recycling device and a recycling method for thermosetting plastic waste. Background technique [0002] The basic component of thermosetting plastics is a polymer with a body structure. After the first molding, it cannot be melted, softened and molded again when reheated. Therefore, it is often used as heat insulation, wear resistance, insulation, and high pressure resistance. electricity and other materials. In order to improve its thermal insulation performance, high temperature resistance, etc., various fillers, such as ceramic powder, are often added in the molding process. [0003] Epoxy resin has the advantages of high insulation performance, high structural strength and good sealing performance, and is widely used in the insulation and packaging of high and low voltage electrical appliances, motors and electronic components. Especially in t...
