Description

Technical Field

[0001] The utility model relates to the technical field of artificial diamond separation, in particular to an artificial diamond fluidized separation device. Background Art

[0002] Synthetic diamond is obtained by subjecting carbonaceous raw materials such as graphite to ultra-high pressure and high temperature to transform them from a solid or molten state into diamond. During the production of synthetic diamond, it is necessary to separate the synthetic diamond from impurities such as graphite, amorphous carbon, silicon dioxide, and metal elements for purification and grading.

[0003] The artificial diamond fluidized separation device of CN201921017422.4 includes a bed body. A fluidization chamber is provided inside the bed body. An overflow port is provided at the top of the fluidization chamber. The artificial diamond fluidized separation device further includes an ultrasonic generating device. The ultrasonic generating device is arranged on the bed body or inside the fluidization chamber of the fluidized bed and is used to utilize the cavitation effect of ultrasonic waves to destroy the surface bonding force between the artificial diamond and the impurities, so that the impurities on the surface of the artificial diamond are separated from the artificial diamond. The ultrasonic generating device is provided below the distributor of the fluidized bed. There is a spaced space in the vertical direction between the ultrasonic generating device and the distributor. The spaced space is communicated with a liquid inlet, and the liquid inlet is used to introduce a liquid flow into the spaced space to transport the materials in the spaced space above the distributor.

[0004] However, it is not possible to make an adaptability adjustment for materials with different weight differences, and the overflow height is always fixed. Therefore, when overflowing very fine and greatly different materials such as overflow graphite powder, it needs to overflow through the same overflow height, which wastes a large amount of energy and reduces the separation efficiency. Summary of the Utility Model

[0005] The utility model provides an artificial diamond fluidized separation device, which solves the disadvantages in the prior art that it is not possible to make an adaptability adjustment for materials with different weight differences, wastes energy, and reduces the separation efficiency.

[0006] The utility model provides the following technical solutions:

[0007] Artificial diamond fluidized separation equipment, including a bed body, a fluidization chamber and an overflow chamber are arranged in the bed body, a water distributor is arranged in the fluidization chamber, a feeding port is arranged on the bed body, and the feeding port feeds materials into the fluidization chamber, and a total discharge pipe is arranged in the overflow chamber; the fluidization chamber and the overflow chamber are separated by a fixed overflow plate and a liftable overflow plate. By changing the height of the liftable overflow plate, the overflow height can be changed, and by changing the height of the liftable overflow plate, the height of the overflow port can be changed. After feeding, first stop the liftable overflow plate at a low position, and then adjust the water outlet speed to separate the graphite powder in the materials. Since the weight difference between the graphite powder and the coarse-grained graphite and diamond is relatively large, only a short overflow height is required to complete the separation. By reducing the overflow height, the separation efficiency can be improved and the energy consumption can be reduced. Subsequently, raise the liftable overflow plate to separate the coarse-grained graphite, thereby lengthening the overflow height, so that there is enough distance between the coarse-grained graphite and the diamond for separation, and thus the graphite powder, coarse-grained graphite and diamond can be classified and collected.

[0012] Preferably, the water supply branch pipes of the first distribution pipe and the second distribution pipe are arranged staggeredly, and the water distribution uniformity is improved by arranging the water supply branch pipes staggeredly.

[0013] Preferably, the first distribution pipe is located at the bottom of the bed body, and the second distribution pipe is flush with the top of the fixed overflow plate. By setting the first distribution pipe and the second distribution pipe at different heights, when the overflow height increases, the water distribution speed can be substantially the same in the vertical direction, improving the water distribution uniformity and the separation efficiency.

[0014] Preferably, a water finding slope is provided at the bottom of the overflow chamber to collect the overflowed materials. The bottom of the water finding slope is connected to a discharge main pipe that penetrates the bed body.

After feeding, first stop the liftable overflow plate at a low position, and then adjust the water discharge speed to separate the graphite powder in the materials. Since the weight difference between the graphite powder and the coarse-grained graphite and diamond is relatively large, only a short overflow height is required to complete the separation. By reducing the overflow height, the separation efficiency can be improved and the energy consumption can be reduced. Then, raise the liftable overflow plate to separate the coarse-grained graphite, thereby lengthening the overflow height, so that there is enough distance between the coarse-grained graphite and the diamond for separation, and thus the graphite powder, the coarse-grained graphite and the diamond can be classified and collected.

[0018] In the present invention, a fixed overflow plate and a liftable overflow plate form an overflow port with a variable height, thereby changing the separation path distance, being applicable to materials with different weight differences, improving the applicability and reducing the energy consumption.
