[0010] As a preferred technical solution of this utility model: the other end of the spring is fixed to the inner wall of the baffle, and the outer wall of the mounting rod is slidably sleeved with the inner wall of the baffle.

[0011] Compared with the prior art, the present invention has the following beneficial effects:

[0012] 1. This raw material screening device for continuous casting tundish flow stabilizer production uses a motor driven by a controller to rotate the screw. Raw materials placed through the feed inlet fall onto the inner wall of the feed cylinder. The screw pushes the raw materials along the rotation path forward, conveying them from the inner wall of the feed cylinder to the inner wall of the screen cylinder. The motor, via the screw, drives a rotating rod, which in turn drives a round rod and a rotating plate to rotate. The rotating plate impacts and vibrates against the inner wall of the screen cylinder, screening the raw materials. Materials smaller than the diameter of the screen cylinder's round holes fall through the screen cylinder to the inner wall of the fine material outlet for discharge, while materials larger than the diameter of the screen cylinder's round holes fall through the screen cylinder to the inner wall of the coarse material outlet for discharge.

[0013] 2. The raw material screening device for the continuous casting tundish flow stabilizer uses a baffle that slides onto the outer wall of the screen cylinder. External force pushes the mounting rod, which compresses the spring force, causing the baffle to detach from the outer wall of the screen cylinder for disassembly. This facilitates the cleaning of blocked screen holes and raw materials inside the screening cylinder. External force releases the screening cylinder, and the spring force pushes the mounting rod to engage with the limiting hole, thus installing the baffle and preventing the screened raw material from mixing with the raw material blocked on the inner wall of the screen cylinder.

A controller 4 is fixedly installed on the outer wall of the support 1. A feed cylinder 6 is fixedly installed on the top outer wall of the support 1. A motor 7 is fixedly installed on the outer wall of the feed cylinder 6. A screw 17 is fixedly assembled on the power output shaft of the motor 7. A rotating rod 10 is fixedly installed on the outer wall of the screw 17. A round rod 12 is fixedly installed on the outer wall of the rotating rod 10. A rotating plate 11 is fixedly installed on the outer wall of the round rod 12. A screening cylinder 5 is fixedly installed on the top outer wall of the support 1. A screen cylinder 16 is fixedly installed on the inner wall of the screening cylinder 5. A baffle 13 is slidably sleeved on the outer wall of the screen cylinder 16. A spring 14 is fixedly installed on the inner wall of the baffle 13. An installation rod 15 is fixedly installed at one end of the spring 14. A limit hole 18 is opened on the inner wall of the screening cylinder 5. A sealing plate 9 is slidably connected to the inner wall of the screening cylinder 5. A coarse material inlet 3 and a fine material inlet 2 are fixedly installed at the bottom of the screening cylinder 5.

[0022] In the above structure, a round rod 12 is installed to support the rotating plate 11, so that the rotating plate 11 impacts the raw material on the inner wall of the screen cylinder 16 to achieve screening.

[0023] In a preferred embodiment: a feed inlet 8 is fixedly installed on the top of the feed cylinder 6, and an electrical connection is formed between the controller 4 and the motor 7.

[0024] In the above structure, the screw 17 is driven to rotate by the motor 7 through the controller 4, so that the raw material placed by the personnel through the feed port 8 falls onto the inner wall of the feed cylinder 6. The raw material is pushed forward by the screw 17 along the rotation path, and the raw material on the inner wall of the feed cylinder 6 is transported to the inner wall of the screen cylinder 16, thereby improving the feeding rate.

[0025] In a preferred embodiment, there are several rotating plates 11, and all of the rotating plates 11 are located on the outer wall of the rotating rod 10.

[0026] In the above structure, the motor 7 drives the rotating rod 10 to rotate through the screw 17, which in turn drives the round rod 12 and the rotating plate 11 to rotate, thereby causing the rotating plate 11 to drive the raw material on the inner wall of the screen cylinder 16 to be screened.

[0027] In a preferred embodiment: the inner diameter of the screening cylinder 5 is larger than the outer diameter of the screen cylinder 16, and the fine material inlet 2 corresponds to the bottom outer wall of the screen cylinder 16.

[0028] In the above structure, the rotating plate 11 impacts and vibrates the inner wall of the screen cylinder 16 to screen the material. The material smaller than the diameter of the hole in the screen cylinder 16 falls through the screen cylinder 16 to the inner wall of the fine material outlet 2 for discharge, while the material larger than the diameter of the hole in the screen cylinder 16 falls through the screen cylinder 16 to the inner wall of the coarse material outlet 3 for discharge.

[0029] In a preferred embodiment: the outer wall of the baffle 13 is in contact with the inner wall of the screening cylinder 5, and the outer wall of the mounting rod 15 is engaged with the inner wall of the limiting hole 18.

[0030] In the above structure, the baffle 13 is slidably sleeved on the outer wall of the screen cylinder 16, and the mounting rod 15 is pulled by external force to make the mounting rod 15 and the limiting hole 18 engage, so that the baffle 13 can be quickly installed on the outer wall of the screen cylinder 16 and the inner wall of the screening cylinder 5, thus avoiding the mixing of the screened raw material with the raw material blocked to the inner wall of the screen cylinder 16.

[0031] In a preferred embodiment, the other end of the spring 14 is fixed to the inner wall of the baffle 13, and the outer wall of the mounting rod 15 is slidably connected to the inner wall of the baffle 13.

[0032] In the above structure, by pushing the mounting rod 15 with external force, the mounting rod 15 compresses the elastic force of the spring 14, causing the baffle 13 to detach from the outer wall of the screen cylinder 16 for disassembly. This facilitates the cleaning of the blocked screen holes and the raw materials in the inner wall space of the screening cylinder 5. By releasing the screening cylinder 5 with external force, the elastic force of the spring 14 pushes the mounting rod 15 to engage with the limiting hole 18, thus enabling the baffle 13 to be installed.

[0033] Working principle: The baffle 13 is slidably sleeved on the outer wall of the screen cylinder 16. External force pushes the mounting rod 15, which compresses the spring force of the spring 14, causing the baffle 13 to detach from the outer wall of the screen cylinder 16 for disassembly. This facilitates the cleaning of raw materials blocked in the screen holes and the inner wall space of the screening cylinder 5. External force releases the screening cylinder 5, and the spring force of the spring 14 pushes the mounting rod 15 to engage with the limiting hole 18, thus installing the baffle 13 and preventing the screened raw materials from mixing with the raw materials blocked in the inner wall of the screen cylinder 16. The controller 4 drives the motor 7 to rotate the screw 17, allowing personnel to pass through... The raw material placed at the feed inlet 8 falls onto the inner wall of the feed cylinder 6. The raw material is pushed forward along the rotation path by the screw 17, which transports the raw material on the inner wall of the feed cylinder 6 to the inner wall of the screen cylinder 16, thereby increasing the feeding rate. The motor 7 drives the rotating rod 10 to rotate through the screw 17, which in turn drives the round rod 12 and the rotating plate 11 to rotate. The rotating plate 11 impacts and vibrates the screen on the inner wall of the screen cylinder 16, and the raw material smaller than the diameter of the round hole of the screen cylinder 16 falls onto the inner wall of the fine material outlet 2 for discharge, while the raw material larger than the diameter of the round hole of the screen cylinder 16 falls onto the inner wall of the coarse material outlet 3 for discharge.

[0034] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
