Embodiment Construction
[0010] The ultrafine powder treatment process is as follows: Put the ultrafine powder to be processed into the top hopper of the machine, turn on the power of the main engine, and start the heating element, axial flow fan and dust collector at the same time, at this time, the temperature in the heating tube cavity will gradually increase. When the internal temperature of the heating tube is stable (80-200°C according to different raw materials), start the feeding motor, and the screw feeding device connected to the feeding motor will evenly feed the material at a speed of 0.1-0.5Kg / min The ultra-fine powder in the silo is pushed into the top of the heating tube cavity, and the material falls by gravity, and is heated by the hot air blown by the axial flow fan during the falling process, the surface of the material softens and sticks to each other, and naturally falls into the finished product silo. Because the finished product silo communicates with the heating tube cavity, the...

Abstract
The invention relates to a hot air treatment method for superfine powder and a hot air treatment machine for realizing the method. The treatment method is to make the superfine powder with a particle size of less than 5 μm stick after hot air treatment, so that more than 80% of the ultrafine powder particle size is greater than 0.1mm; the hot air treatment machine includes a frame, a silo, a feeding pipeline, Heating pipe cavity, finished product silo, cyclone separator, dust collector, heating pipeline, heating device, axial flow fan, reducer and feeding motor; there is a spring-type screw connected to the motor in the silo, and the feeding pipe The heating pipe is connected with the heating pipe cavity, and the heating pipe chamber is connected with the finished product silo equipped with a sealing cover. The heating device is fixed on the pipe wall of the heating pipe; the dust collector is connected with the cyclone separator, and the negative pressure hose of the cyclone separator Connect with sealing cap. The invention not only reduces the product cost, saves waste disposal costs, but more importantly, realizes the production of toner without waste powder discharge, avoids environmental pollution, ensures full utilization of raw material resources, and achieves economic and social benefits. Unite.
Description
technical field [0001] The invention relates to a processing method for superfine powder separated in the toner production process, in particular to a hot air processing method for superfine powder and a hot air processing machine for realizing the method. Background technique [0002] In the process of toner production, about 4% of ultra-fine powder is produced, with a particle size of 5 μm or less. Due to the limitations of current toner production equipment, these ultrafine powders cannot be recycled, and toner manufacturers can only treat them as waste, which not only requires a lot of processing costs, but also easily pollutes the environment. Therefore how to solve the reutilization problem of ultrafine powder is an important subject before technicians. Contents of the invention [0003] The purpose of this invention is to reprocess the ultrafine powder separated in the production process of toner, so that it can reach the particle size required by the raw material ...
