Technical Field

[0001] The utility model relates to the technical field of zinc powder processing, in particular to a centrifugal electric grinding mill. Background Art

[0002] Zinc powder is a powdered metallic element, usually gray in color, and is an important industrial raw material and chemical product.

[0003] In the prior art, before using a centrifugal electric grinder to perform fine grinding of zinc material, the operator usually uses a shovel to put an appropriate amount of zinc material into the equipment. However, considering that in some cases the shovel is too large and the inlet is too small, during the actual process of feeding the zinc material into the equipment, the zinc material often tends to spill outside the inlet end, which is not conducive to collection and subsequent processing. Therefore, a centrifugal electric grinder is proposed to address the above problem. Utility Model Content

[0010] Preferably, the feed guide groove is a rhombus tubular structure extending to the interior of the guide bin, a conductive connection is set between the feed guide groove and the short pipe, the right side of the spiral conveying auger extends to the interior of the feed guide groove, and the output end of the drive motor passes through the collection bottom frame and is connected to the spiral conveying auger.

[0011] Compared with the prior art, the beneficial effects of the present invention are:

[0012] In the utility model, the outer shell cover, fixed side plate, collecting bottom frame, inclined table, driving motor and spiral conveying auger are provided, which can facilitate the centrifugal electric grinding mill to quickly introduce an appropriate amount of zinc material into the interior of the equipment through a shovel. In order to solve the problem of material spillage during feeding, the entire equipment can utilize the secondary feeding structure composed of the outer shell cover, fixed side plate, collecting bottom frame, inclined table, driving motor and spiral conveying auger to first collect the zinc material, and then transport it into the interior of the equipment, so as to cooperate with the equipment to complete efficient feeding operation.

[0019] A centrifugal electric grinding mill includes a material guide bin 1, a feed bevel 2 is provided on the left side of the material guide bin 1, a feed guide groove 3 is connected to the discharge end of the feed bevel 2, an outer shell cover 4 is provided on the outside of the feed bevel 2, fixed side plates 5 are provided at the front and rear ends of the outer shell cover 4, a collecting bottom frame 6 is provided on the bottom of the outer shell cover 4, inclined platforms 7 are provided at the front and rear ends of the inner side of the collecting bottom frame 6, a spiral conveying auger 9 is provided between the front and rear sets of inclined platforms 7, a short pipe 10 is connected to the side of the collecting bottom frame 6 close to the material guide bin 1, and a drive motor 8 is fixedly installed on the side of the collecting bottom frame 6 away from the material guide bin 1.

[0020] like Figure 1 As shown, the bottom of the material guide bin 1 is connected to the fine grinding bin 14, the lower part of the fine grinding bin 14 is provided with a speed reducer unit 16, and one side of the fine grinding bin 14 is provided with two symmetrically arranged maintenance doors 15. By setting a set of upper and lower maintenance doors 15, this structural setting will facilitate subsequent operators to open the fine grinding bin 14 and then perform regular maintenance on the grinding discs provided therein; the top of the material guide bin 1 is connected to the powder selection bin 11, and the top of the powder selection bin 11 is fixedly installed with a powder selection drive 12, and a discharge port 13 is provided adjacent to one side of the powder selection drive 12. The discharge port 13 and the internal conduction setting of the material guide bin 1 are arranged. After the equipment realizes the fine grinding operation of the zinc powder through the grinding disc inside the fine grinding bin 14, the start-up of the powder selection device will draw out the qualified zinc powder upward, so that it can be brought out of the equipment through the inside of the discharge port 13.

[0021] like Figure 1 、 Figure 2 and Figure 3 As shown, the fixed side plate 5 and the material guide bin 1 are fixedly connected by bolts, and a rectangular square groove structure is formed between the outer shell cover 4 and the feed bevel 2. After the outer shell cover 4 is put on the outside of the feed bevel 2, the outer shell cover 4 can be firmly defined by the fixed connection between the fixed side plate 5 and the material guide bin 1; the feed guide groove 3 is a rectangular tubular structure extending to the interior of the material guide bin 1, and a conductive setting is set between the feed guide groove 3 and the short pipe 10. The right side of the spiral conveying auger 9 extends to the interior of the feed guide groove 3, and the output end of the drive motor 8 passes through the collecting bottom frame 6 and is connected to the spiral conveying auger 9. Since the spiral conveying auger 9 extends to the interior of the feed guide groove 3, under the mutual conductive setting, the spiral conveying auger 9 will transport part of the zinc powder to the interior of the feed guide groove 3 from left to right after it rotates.

[0022] Working process: The electric energy required for the startup and operation of the grinding equipment in the present invention is all from an external power supply. Since the outer shell cover 4 is pre-assembled with the fixed side plate 5 and the guide bin 1, the secondary feeding structure composed of the outer shell cover 4, the fixed side plate 5, the collecting bottom frame 6, the inclined platform 7, the driving motor 8 and the spiral conveying auger 9 is assembled on the outside of the feed bevel 2, and the spiral conveying auger 9 is extended to the inside of the feed guide groove 3 through the internal fit of the short pipe 10. When the zinc raw material is preliminarily processed into small granular zinc material, and a shovel is needed to allow an appropriate amount of zinc material to be quickly introduced into the interior of the equipment through the cooperation of the feed bevel 2 and the feed guide groove 3, as the outer shell cover 4 set on the outside of the feed bevel 2 is able to handle part of the zinc material spilled from the edge of the feed bevel 2 The zinc material is collected and concentrated so that it can slide down between a group of inclined platforms 7. At the same time, the equipment can start the driving motor 8 to drive the spiral conveying auger 9 to realize rotary rotation, thereby utilizing the generated spiral conveying force to send part of the scattered and collected zinc material into the inside of the feed guide trough 3 from left to right, until part of the zinc material can be sent into the inside of the guide bin 1 together with the original zinc material. Then, when the zinc material falls into the inside of the fine grinding bin 14 through the guide bin 1, the equipment will perform fine grinding operation on the zinc material through the centrifugal grinding disc assembly inside the fine grinding bin 14. At the same time, the equipment will also start the powder selection drive 12 to drive the powder selection rotor inside the powder selection bin 11 to realize rotation, so as to extract the finely ground qualified powder, until the powder can be brought out of the entire equipment through the inside of the discharge port 13, thereby completing the entire zinc powder processing operation.
