本発明は、例えば耐火物粉末のような粉末を極めて短い
距離搬送するのに利用され得る電磁式粉体搬送装置に関
するものである。DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to an electromagnetic powder conveying device that can be used to convey powder, such as refractory powder, over extremely short distances.
従来、粉体の搬送にはガス、一般的には空気を用いて圧

る。Conventionally, a method of pressure-feeding using gas, generally air, has been widely adopted for conveying powder. For example, when transferring refractory powder, the powder is put into a pressure tank, compressed air is used,
The preferred method is to use propane, oxygen, or nitrogen gas to transport the material under pressure through piping, and this method is suitable for transporting relatively long distances. Further, such a conveying method using pressure feeding is also applied directly to spraying and thermal spraying of refractory powder.

タンク、配管あるいは集塵装置が必要となシ、そのため
設備がおおがかシとなシ過ぎ、据付面積も広くな力、高
コストとなる。By the way, the conventional method of transporting powder by pressure feeding using air, propane, oxygen, 9-component gas, etc. tends to generate dust, and there is a problem of dust pollution in terms of environmental hygiene. Also, this type of conveyance method is not suitable when the conveyance distance is relatively short. In other words, even when using gas to transport powder over extremely short distances, blow tanks, compressors, storage tanks, piping, or dust collectors are required, making the equipment too large and requiring a small installation area. Wide range of power and high cost.

防止することは困難である。Roughly speaking, when the above powder conveyance method is applied to spraying or thermal spraying of refractory powder, 1% Lt- is emitted when the powder is ejected from the nozzle or burner tip, and this dust generation cannot be completely eliminated. It is difficult to prevent this.

It is an object of the present invention to provide an electromagnetic powder conveying device that can be easily incorporated into a powder processing device such as a laser or a solvent device, and is particularly suitable for conveying relatively short distances.

に調節することができる。In the electromagnetic powder conveying device according to the present invention configured as described above, the excitation of the magnetic force generating coils wound around the core is suitably controlled by the control device, that is, the voltage training in the control device is applied to each magnetic force generating coil. Supplying an alternating current at the desired voltage level through the regulator creates a magnetic force of constantly varying magnitude within the core. As a result, the surface is coated with powder of a magnetic material such as iron, nickel, cobalt or an alloy thereof from one end of the powder conveying path located adjacent to the core, for example via a feed hopper. When the powder is supplied, it can be transported by the generated deer along the transport path from one end to the other end. In this case, l
By suitably controlling the voltage regulator in the IJ control device, the powder conveyance speed and thus the conveyance JJkt can be easily adjusted at will.
