Description
Technical Field
The invention relates to the field of powder processing, in particular to a fluidization and screening processing device and a processing method of ceramic powder.
Background
During the process that ceramic powder enters the storage bin from the charging barrel, the conditions of piling, balling and the like easily occur at the position of the ceramic powder in the charging barrel. The reason is that: in order to make ceramic powder flow to the bin smoothly from the charging bucket, a vibration device is arranged to make the charging bucket generate tiny vibration continuously, but the vibration also makes the inner surface of the charging bucket generate friction with the ceramic powder continuously, so that the inner surface of the charging bucket and part of the ceramic powder have static electricity, and the static electricity can make the ceramic powder gather and agglomerate. In addition, after ceramic powder flows out of the charging barrel, ceramic powder with different diameters needs to be screened, and continuous screening is not usually performed in order to save electricity. But the ceramic powder is screened in batches, that is, quantitatively screened. The quantitative screening is an intermittent screening mode, so that the processing cost can be saved. In addition, in order to allow the ceramic powder to smoothly pass through the fine mesh of the screen, the sieving device needs to be vibrated finely and rapidly. However, such vibration tends to cause static electricity to the ceramic powder in the sieving device, so that the ceramic powder is accumulated and agglomerated, and the ceramic powder is prevented from passing through the sieve.
Therefore, how let the ceramic powder in the charging barrel disperse on the fluidization board, even get into the feed bin from the charging barrel, then how let ceramic powder automatic, quantitative drop screening smooth in the screening plant still need further to effectual, automatic completion ceramic powder processing of earlier stage.
The following patents are found to have similarities with the present invention through domestic search: the invention discloses a ceramic powder quantitative processing and recycling device, which is provided with the application number of CN202021021725.6 and is named as a ceramic powder quantitative processing and recycling device, and comprises a supporting frame, a machine body, a screening mechanism and grinding equipment; the machine body is arranged on the support frame, a treatment cavity is arranged in the machine body, a first feed port communicated with the treatment cavity is arranged at the top of the machine body, a first discharge port communicated with the treatment cavity is arranged at the bottom of the machine body, and a second discharge port communicated with the treatment cavity is arranged at the first side of the machine body; the screening mechanism comprises a first screen, the first screen is arranged between the first feeding hole and the first discharging hole, and the lower end of the first screen is arranged corresponding to the second discharging hole; the grinding equipment is arranged on the support frame, a second feed port is formed in the grinding equipment, and the second feed port is communicated with a second discharge port; pour waste porcelain powder into the treatment intracavity from first discharge gate, the waste porcelain powder up to standard passes first screen cloth and discharges from first discharge gate department, and the waste porcelain powder that can not pass first screen cloth then follow second discharge gate and second feed inlet entering grinding device in continue to process into up to standard ceramic powder can.
Although the above patent also relates to the sieving of ceramic powder, the sieving device does not employ an ultrasonic vibration mechanism and a vibration hammer to smoothly sieve the ceramic powder in the sieve. The ultrasonic vibration mechanism can enable ceramic powder with tiny particles to pass through the screen more smoothly, so that the screening is carried out more smoothly.

As shown in fig. 1, 2 and 3, the charging barrel comprises a barrel wall 11 and a barrel bottom 13, a fluidization plate 12 is arranged in the charging barrel, and through holes are formed between the fluidization plate 12 and the barrel bottom 13. An inner side wall 14 is arranged at the through hole, the outer side of the fluidization plate 12 is fixedly connected with the barrel wall 11, the upper end of the inner side wall 14 is connected with the inner side of the fluidization plate 12, and the lower end of the inner side wall 14 is connected with the inner side of the barrel bottom 13.

The fluidization plate 12, the barrel wall 11, the barrel bottom 13 and the inner side wall 14 enclose a closed ventilation cavity, and the ventilation mechanism comprises a gas source, a gas guide pipe 4 and a ventilation cavity. The fluidized feeding device also comprises a material guide pipe 21, the upper end of the material guide pipe 21 is connected with the lower end of the inner side wall 14, and the lower end of the material guide pipe 21 is connected with a storage bin 22. One end of the air duct 4 is connected with an air source, and the other end of the air duct 4 passes through the barrel wall 11 and extends into the ventilation cavity. The air source, which is not shown in the drawings, may be an air compressor or other air supply device, and when activated, air flows through the air duct 4 into the ventilation cavity. Since only the fluidization plate 12 of the aeration cavity is provided with air holes to allow air to flow out, starting the air source can generate a plurality of tiny air columns on the fluidization plate 12. These numerous tiny gas columns blow up the ceramic powder on the fluidization plate 12, thereby dispersing the ceramic powder on the surface of the fluidization plate 12 without agglomeration or balling.
In order to make the ceramic powder on the fluidization plate 12 flow to the inner sidewall 14 and then enter the bin 22 through the inner sidewall 14, the surface of the fluidization plate 12 is a conical surface in this embodiment, that is: the height of the outer side of the fluidization plate 12 is greater than the height of the inner side of the fluidization plate 12. The outer side of the fluidization plate 12 refers to the side toward the tub wall 11, and the inner side of the fluidization plate 12 refers to the side toward the inner side wall 14.

The partition 15 may be in a grid shape, and the condition of the ceramic powder piling and balling under the electrostatic action can be well known by observing the condition that the ceramic powder at the partition 15 flows into the inner side wall 14. Thereby controlling the height at which the small gas columns on the fluidization plate 12 can blow up the ceramic powder by adjusting the gas pressure of the gas output from the gas source, and thus adjusting the degree to which the ceramic powder is dispersed on the surface of the fluidization plate 12.
