[0017] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.
[0018] like Figure 1-4As shown, a secondary deagglomeration and classifying device for ceramic powder accumulation includes a collecting chamber 1, the lower end of the collecting chamber 1 is connected to a discharge port 2, the connection between the collecting chamber 1 and the discharge port 2 is connected to a side air inlet 3, the upper end of the collecting chamber 1 is fixedly connected to a deagglomeration chamber 4, a deagglomeration structure 5 is fixedly installed on the surface of the deagglomeration chamber 4, a side inlet hopper 6 is fixedly connected to the surface of the deagglomeration chamber 4 above the deagglomeration structure 5, and the upper end of the deagglomeration chamber 4 is fixedly connected to a grading structure 7;
[0019] The depolymerization structure 5 includes a nozzle holder 501, a Laval nozzle 502, an adjusting bolt 503, an air inlet ring pipe 504 and a connecting flange 505. There are four nozzle holders 501 in total, and they are evenly arranged and installed on the surface of the depolymerization chamber 4. One end of the nozzle holder 501 is located inside the depolymerization chamber 4 and is fixedly installed with a Laval nozzle 502. The other end of the nozzle holder 501 is connected to the same air inlet ring pipe 504. The surface of the air inlet ring pipe 504 is fixedly connected with a connecting flange 505. The rear end of the nozzle holder 501 is spirally installed with an adjusting bolt 503. The air inlet ring pipe 504 is connected to the external air supply equipment through the connecting flange 505, and then the air inlet ring pipe 504 will grind Compressed air is evenly supplied to the nozzle seat 501 and ejected through the Laval nozzle 502. The ejected supersonic airflow realizes the deagglomeration of the material. An adjusting bolt 503 is provided at the rear end of the nozzle seat 501. By screwing the adjusting bolt 503, the insertion length of the Laval nozzle 502 can be adjusted, thereby controlling the spraying distance of the Laval nozzle 502 and adjusting the deagglomeration intensity so that the impurities in the material can be fully deagglomerated and separated. In this way, the problem of material accumulation during the classification process, which affects the yield and purity of the material, can be solved. An inlet hole is provided on the surface of the deagglomeration chamber 4, and a sealing hole cover is provided at the edge of the inlet hole. The grading structure 7 includes a grading chamber 701, a motor 702, an outlet The material pipe port 703, the ceramic blade metal classifying wheel 704 and the recoil air sleeve 705, the outer surface of the classification chamber 701 is fixedly installed with a motor 702, the output end of the motor 702 is located inside the classification chamber 701 and is fixedly installed with a ceramic blade metal classifying wheel 704, the surface of the classification chamber 701 is interspersed with a discharge pipe port 703, and the outer surface of the discharge pipe port 703 is fixedly sleeved with a recoil air sleeve 705. When the equipment is working, the equipment works under negative pressure. After the material enters the depolymerization chamber 4, it will be subjected to an upward negative pressure suction force. The large particles are directly settled to the collection chamber 1 due to the action of gravity, while the smaller particles and the small particles after depolymerization are sucked into the separation chamber 1. The grade chamber 701 is screened by the ceramic blade metal classifying wheel 704. The material with appropriate particle size enters the ceramic blade metal classifying wheel 704 and is discharged from the discharge pipe 703. The unsuitable material falls back to the depolymerization chamber 4 to continue depolymerization or falls into the collection chamber 1. The number of revolutions of the ceramic blade metal classifying wheel 704 can be adjusted by the motor 702. The materials of different particle sizes can be screened by controlling the speed of the ceramic blade metal classifying wheel 704. The recoil gas sleeve 705 is docked with the ceramic blade metal classifying wheel 704, and gas is filled into the recoil gas sleeve 705 so that the recoil gas sleeve 705 will continuously spray gas to the gap where it docks with the classifying wheel to prevent the material from leaking from the gap.
[0020] It should be noted that the utility model is a secondary deagglomeration and classifying equipment for ceramic powder accumulation. The equipment adds a crushing process before the classification process. By crushing large impurity particles in advance, the accumulation problem of the classification process is solved. After the crushed material enters from the side entry hopper 6 entrance, the large particles accumulated with impurities will settle downward and fall into the deagglomeration chamber 4. The Laval nozzle 502 inside the side entry hopper 6 will spray out a supersonic airflow to blow away the large particles and deagglomerate them. Materials of appropriate particle size fall directly into the collecting chamber 1 and are taken away by the discharge port 2. Small particles and deagglomerated small particles are sucked into the classification chamber 701 and screened by the ceramic blade metal classification wheel 704. Materials of appropriate particle size enter the ceramic blade metal classification wheel 704 and are discharged from the discharge pipe 703. Unsuitable materials fall back into the classification chamber 701 and continue to deagglomerate or fall into the collection section.
