Embodiment Construction

[0017] Such as figure 1 with figure 2 As shown, the nanoscale powder feeding device of the present invention is composed of a sealing cabinet 1, a conveyor 2, an exhaust filter device 3, and an automatic bag opening machine 4. The structure of each part is as follows:

[0018] There is a partition door in the airtight cabinet 1 to divide the airtight cabinet 1 into multiple isolation rooms. The first isolation room 5 is connected with the exhaust air filter equipment 3 through the exhaust passage 6. The lower part of the side wall of the first isolation room 5 is provided with an air inlet 5A. . Due to the use of conventionally used exhaust air filter equipment 3, the air inlet 5A is opened when the exhaust air filter equipment 3 works, and the air inlet 5A is closed when the exhaust air filter equipment 3 is out of service. The first isolation chamber 5 is provided with an outer door 7, and the packaging bag 16 is put into the bottom of the first isolation chamber 5 when ...

Abstract

A feeder for feeding nano-powder from its packing bag to apparatus or storage container is composed of an sealed cabinet, a conveying unit, an exhaust filter and an automatic bag opener. Multiple partition gates are used to partition said sealed cabinet into more isolated chambers for preventing the escape of nano powder. Its advantages are less powder dust pollution, and recovering packing bags.

Description

technical field [0001] The invention relates to a nanoscale powder feeding device, in particular to a device for unloading nanoscale powder from a packaging bag and adding it to equipment or a storage container. Background technique [0002] Nano-scale powders are widely used more and more. During the processing process, mixing, banburying, extrusion, reaction and other processes are often involved. The powder raw materials are unloaded from the packaging bag and enter the process of mixing, banburying, extrusion or reaction. When using advanced equipment and storage containers, nano-scale powder is easily dispersed in the air, flying nano-scale dust and dust attached to discarded packaging bags are very serious environmental pollution, and the operating environment is very harsh. It not only affects the health of operators but also affects safe production operations. A degassing device for an ultrafine powder packaging machine is disclosed in "Degassing device for ultrafin...
