Description

Technical Field

[0001] The utility model relates to the field of flash roasting, in particular to a flash oxygen roasting device. Background Art

[0002] Nano zinc oxide is a chemical raw material widely used in the industrial field. The raw material required for the production of nano zinc oxide is zinc oxide powder. The zinc oxide powder is acid-leached in concentrated sulfuric acid and filtered to obtain basic zinc carbonate filter blocks. The filter blocks are then washed and filtered, and the washed filter blocks are dried by flash evaporation. Finally, the dried powder is calcined at high temperature to obtain nano zinc oxide powder.

[0003] The relevant nano zinc oxide flash roasting system includes a flash furnace, a calcining furnace, a stirring mechanism and a blower. The flash furnace is used to dry the filter block, and the calcining furnace is used to calcine the dried material. The stirring mechanism is arranged in the flash furnace. When the filter block enters the flash furnace, the filter block is large in volume and the heat exchange with the high-temperature air is slow. The stirring mechanism can stir the filter block and break the filter block into small pieces, thereby improving the efficiency of the filter block drying. The blower is connected to the flash furnace and is used to blow gas into the flash furnace. A discharge pipe is connected to the flash furnace, and the discharge pipe is connected to the calcining furnace. The discharge pipe is connected to the upper top of the flash furnace. The blower can blow the dried material mixed with air upward, and then allow the material to enter the calcining furnace through the discharge pipe. Particles with larger particle size are difficult to blow up, and thus continue to remain in the flash furnace for crushing.

[0004] However, the existing flash furnace cannot completely blow up the materials in the flash furnace when blowing out the air, and the effect achieved is not ideal. Moreover, when the filter block is broken, there will still be a lot of debris sinking to the bottom and cannot be blown up by blowing from one side. Utility Model Content

[0005] One object of the present invention is to provide a flash oxygen roasting device which can solve at least any aspect of the above-mentioned technical problems.

[0006] A further object of the present invention is to prevent the crushed materials from sinking to the bottom of the furnace body.

[0007] Another further purpose of the utility model is to improve the effect of blowing from the bottom and improve the discharge efficiency.

[0008] In particular, the present invention provides a flash oxygen roasting device comprising a driving motor;

[0009] A flash tank is provided on one side of the drive motor, a cover is provided on the upper part of the flash tank, a discharge pipe communicating with the flash tank is provided on the upper part of the cover, and a feed pipe is provided on one side of the flash tank;

[0010] A blowing part, the blowing part is arranged at the bottom of the flash tank, and the blowing part includes an air inlet pipe, the air inlet pipe is connected to the blowing part, and a tapered block is arranged near the blowing part;

[0011] The crushing part is arranged in the flash tank, and the crushing part includes a crushing rod and a rotating shaft. The crushing rod is arranged at one end of the rotating shaft, and the other end of the rotating shaft is connected to the driving motor.

[0012] Furthermore, the blowing portion is in the shape of an annular channel, and a filter is provided at the air outlet of the blowing portion.

[0013] Furthermore, the air inlet pipes are arranged in a circular array with the blowing portion as the center.

[0014] Furthermore, the air outlet of the blowing part is directly opposite to the discharge port of the discharge pipe.

[0015] Furthermore, a stopper is provided at the lower portion of the filter screen, and the stoppers are arranged in a ring array with the conical block as the center.

[0016] Technical effects and advantages of this utility model:

[0017] The utility model provides a conical block and a blowing part matched with the execution unit at the bottom of the flash tank, and is connected to the blowing part through an air inlet pipe of a ring array, and evenly blows up the material particles crushed at the bottom, so that the material enters the discharge pipe and enters the roasting device through the discharge pipe. When the material enters the flash tank, it is crushed by the crushing rod, and the crushed material slides down through the inclined surface of the conical block and reaches the blowing part, and the sliding material is evenly blown up by the blowing part, so as to avoid dead corners and avoid the problem of uneven and insufficient blowing of material particles.
