Description

Technical Field

[0001] This utility model relates to the field of diamond production, specifically to a graphite powder screening device for diamond production. Background Technology

[0002] Diamond is a mineral composed of carbon. Diamonds can be divided into two types: naturally formed and artificially synthesized. Among them, artificially synthesized diamonds are made from graphite under high temperature and high pressure. Diamonds have a wide range of uses, mainly used to manufacture drilling probes and grinding tools. Diamonds with complete shapes are also used to manufacture high-end ornaments such as jewelry. They are very expensive. In the diamond processing process, graphite needs to be screened to facilitate subsequent high temperature and high pressure production. Therefore, graphite powder screening equipment for diamond production is required.

[0003] Existing graphite powder screening equipment for diamond production suffers from uneven and unstable graphite powder feeding during operation, leading to localized damage to the screen, difficulty in removing large amounts of graphite dust, and difficulty in replacing the screen. Furthermore, the purity and quality of the graphite powder are not high enough. Therefore, there is an urgent need for graphite powder screening equipment for diamond production. Utility Model Content

[0004] Based on this, the purpose of this utility model is to provide a graphite powder screening device for diamond production, in order to solve the problems of uneven and unstable graphite powder feeding during the use of existing K diamond production equipment, which leads to local damage to the screen, making it difficult to remove large amounts of graphite dust and replace the screen, and resulting in insufficient purity and quality of graphite powder.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a graphite powder screening device for diamond production, comprising a screen box, an inlet installed on the top of the screen box, a drive motor installed on the top of the inlet, and a guide plate installed on the bottom of the drive motor.

[0007] A collection box is installed on the outer wall of the sieve box, a dust collection fan is installed on the inner wall of the collection box, a filter plate is installed on the inner wall of the collection box, a driven impeller is installed on the side wall of the filter plate, a scraper is installed on the outer wall of the driven impeller, a driving impeller is installed on the inner wall of the collection box, a dust collection pipe is installed on the side wall of the collection box, and a dust collection hood is installed on the outer wall of the dust collection pipe.

[0008] Preferably, the guide plate is movably connected to the feed inlet, and the side wall of the guide plate is tightly fitted to the inner wall of the feed inlet.

[0009] Preferably, the guide plate is spirally arranged, and the guide plate forms a rotating structure with the feed inlet through a drive motor.

[0010] Preferably, the screen is threadedly connected to the screen frame, and the top of the screen is tightly fitted to the bottom of the vibrating motor.

[0011] Preferably, the screen frame is inserted into the screen box, and the screen frame and screen box are snap-fitted together.

[0012] Preferably, the driven impeller is meshed with the driving impeller, and the driven impeller is movably connected to the filter screen plate.

[0013] Preferably, the scraper is welded to the driven impeller, and the scraper forms a rotating structure with the filter screen plate through the driven impeller.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] This utility model, through the setting of a feed inlet, drive motor, guide plate and vibration motor, puts graphite powder into the feed inlet and it falls onto the guide plate. Start the drive motor to drive the guide plate to rotate, so that the graphite powder can enter the screen evenly and stably, avoiding the decrease in screening efficiency and local wear of the screen caused by uneven feeding.

[0016] This utility model features a buckle, a screen frame, a screen, and bolts. By unlocking the buckle, the screen frame can be removed to collect larger graphite dust particles on the screen. When the screen needs to be replaced, simply unlock the bolts securing the screen around the perimeter to remove it from the screen frame for replacement.

[0017] This invention utilizes a collection box, a dust extraction fan, a filter plate, a driven impeller, a scraper, a driving impeller, a dust extraction pipe, and a dust extraction hood. The dust extraction fan, pipe, and hood effectively absorb graphite dust generated during the sieving process and collect it in the collection box, preventing secondary pollution of the graphite powder in the air and preventing other impurities from mixing in, thus ensuring the purity and quality of the graphite powder. The filter plate prevents dust from entering the dust extraction fan, and the airflow drives the driving impeller to rotate, causing the scraper on the driven impeller to rotate and clean the filter plate, preventing clogging.
