Technical Field
[0001] This utility model relates to the field of gyratory screen technology, specifically a square gyratory screen. Background Technology
[0002] Graphite crucibles, also known as copper melting pots or copper melting pots, are a type of crucible made from graphite, clay, silica, and wax stone. Natural flake graphite is the main raw material for producing graphite crucibles, and its carbon content is generally required to be above 99%. Natural flake graphite is crushed, sieved, impurities removed, and washed to obtain graphite powder that meets the requirements. Square oscillating sieves are usually used to screen the flake graphite.
[0003] Currently, existing square gyratory screens can only screen one type of raw material for different particle sizes when separating raw materials, and cannot screen raw materials simultaneously, which is inconvenient. In addition, dust is generated inside the square gyratory screen when the raw materials are screened, and the dust will pollute the external environment when the raw materials are discharged.

[0021] like Figures 1 to 4 As shown, this embodiment of the square gyratory screen includes a frame 1 and a screen box body 2. The frame 1 has four connecting rods 3 arranged in a rectangular array and mounted via universal joints inside. Fixed plates 4 are installed on both the front and rear ends of the screen box body 2. The lower ends of the connecting rods 3 are connected to the fixed plates 4 via universal joints. The screen box body 2 can gyrate between the frame 1. A maintenance door 5 is rotatably installed at one end of the screen box body 2, allowing for easy access and maintenance of the interior. Several screens 6 are evenly spaced from top to bottom inside the screen box body 2. These multiple screens 6 can... Multi-layer screening is performed. Several partition plates 7 are installed sequentially from back to front on the upper end of the screen 6. The partition plates 7 and the screen box body 2 form a screening chamber 8. By using the partition plates 7 to divide the screen 6 into multiple screening chambers 8, multiple materials can be screened simultaneously, which is convenient for use. A feed pipe 9 is installed on one side of the uppermost screening chamber 8, and a discharge pipe 10 is installed on the other side of the screening chamber 8. A dust collection device is installed on the upper end of the screen box body 2. The dust collection device is used to extract the dust generated during screening to avoid dust pollution to the external environment.
[0022] Specifically, guide buckets 12 are installed at the lower end of the screen 6 below the screening chamber 8. The bottom of the guide bucket 12 is provided with a discharge hole 13. The discharge hole 13 is located on the side of the guide bucket 12 near the feed pipe 9.
