[0022] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0023] Reference Figure 1-Figure 4 A bromine reduction reaction distillation tower comprises a tower body 1, two trays 2 are installed in the tower body 1, a plurality of filter holes are opened at the bottom of the upper tray 2, a screen 3 is embedded at the bottom of the lower tray 2, and a slag discharge pipe 14 is fixedly connected to the side of the tower body 1;

[0024] A rotating hole is opened on the screen 3, and a rotating shaft 4 is rotatably installed in the rotating hole. A mounting block 5 is fixedly installed on the upper end of the rotating shaft 4, and a rotating shaft 6 is rotatably installed on the surface of the mounting block 5. A rolling roller 7 is fixedly sleeved on the rotating shaft 6. One end of the rotating shaft 4 passes through the tower body 1, and a driving motor 8 is fixedly installed on the lower end of the tower body 1. The output shaft of the driving motor 8 is fixedly connected to the rotating shaft 4. A transmission assembly for driving the rotating shaft 6 to rotate is provided on the screen 3, and the transmission assembly includes a bevel gear 9 fixedly sleeved on the rotating shaft 6 and a bevel gear ring 10 fixedly installed on the screen 3, and the bevel gear 9 is meshed and connected with the bevel gear ring 10.

[0025] After the distillation tower is finished working, the residue inside will fall onto the screen 3, some smaller particles of residue will pass through the screen 3 and fall to the bottom of the tower body 1, and then be discharged from the slag discharge pipe 14, while larger particles of residue will be filtered on the screen 3 to avoid blocking the slag discharge pipe 14;

[0026] Start the driving motor 8, and drive the rotating shaft 4 to rotate through the output shaft of the driving motor 8, and then drive the rotating shaft 6 to rotate horizontally on the screen 3 through the mounting block 5, and then drive the rolling roller 7 to rotate around the rotating shaft 4 through the rotating shaft 6. At the same time, the rotating shaft 6 will drive the bevel gear 9 to rotate around the rotating shaft 4. Since the bevel gear 9 is meshed and connected with the bevel gear ring 10, it will drive the rotating shaft 6 to rotate around itself, and then drive the rolling roller 7 to rotate around itself. When the rolling roller 7 rotates on the screen 3, it will crush the larger particles of residue on the screen 3 into smaller particles of residue, which is convenient for the residue to pass through the screen 3, and prevent the residue from accumulating on the screen 3 and affecting the smaller particles of residue from passing through the screen 3, so as to facilitate the discharge of the residue.

[0027] A mounting rod is fixedly installed horizontally on the side of the mounting block 5, and a scraper 11 is fixedly installed on one end of the mounting rod. The scraper 11 is in sliding contact with the screen 3. A plurality of rectangular holes are opened on the surface of the scraper 11, and the number of rectangular holes is not less than ten. The rotating shaft 4 drives the scraper 11 to rotate around the rotating shaft 4 while rotating. When the rolling roller 7 crushes the residue, some residue will adhere to the screen 3 and block the screen holes. When the scraper 11 slides relative to the screen 3, the residue adhered to the screen 3 will be scraped up, and the scraped residue will pass through the plurality of rectangular holes, thereby preventing the residue from adhering to the screen 3 and blocking the screen holes.

[0028] A disc 12 is fixedly installed at the bottom of the tower body 1. The disc 12 is located directly below the screen 3. A discharge port is opened on the side of the disc 12. A connecting pipe is fixedly installed in the discharge port. The other end of the connecting pipe is fixedly connected to a slag discharge pipe 14. The rotating shaft 4 passes through the disc 12. A plurality of scraping strips 13 are fixedly installed on the rotating shaft 4. The plurality of scraping strips 13 are in sliding contact with the disc 12. The plurality of scraping strips 13 are all in an arc shape, and the protruding directions of the scraping strips 13 are all toward the rotation direction of the rotating shaft 4.

[0029] The residue passing through the screen 3 will fall into the disc 12. When the rotating shaft 4 rotates, it will drive multiple scraping bars 13 to rotate on the disc 12. Since the scraping bars 13 are arc-shaped, they will drive the residue on the disc 12 to move around when rotating. When the residue passes through the discharge port, it will enter the slag discharge pipe 14, thereby discharging the residue in the tower body 1.

[0030] An L-shaped cleaning rod 15 is fixedly installed on the upper end of the mounting block 5. The cleaning rod 15 is in sliding contact with the surface of the rolling roller 7. After the rolling roller 7 rolls the residue, smaller particles of residue may adhere to its surface. During the rotation of the rolling roller 7, its surface will slide relative to the cleaning rod 15. The cleaning rod 15 can clean the surface of the rolling roller 7 to prevent the residue from adhering to the rolling roller 7.

[0031] In the utility model, the output shaft of the driving motor 8 drives the rotating shaft 4 to rotate, and then drives the rotating shaft 6 to rotate horizontally on the screen 3 through the mounting block 5, and then drives the rolling roller 7 to rotate around the rotating shaft 4 through the rotating shaft 6. At the same time, the rotating shaft 4 will drive the rotating shaft 6 to rotate around itself through the transmission component, and then drive the rolling roller 7 to rotate around itself. When the rolling roller 7 rotates on the screen 3, the larger particles of residue on the screen 3 will be crushed into smaller particles of residue, which is convenient for the residue to pass through the screen 3, and the residue can be prevented from accumulating on the screen 3 and affecting the smaller particles of residue from passing through the screen 3, so as to facilitate the discharge of the residue.

[0032] In general, in view of the technical problem that when the sediment residue at the bottom is discharged, larger particles will accumulate on the screen 3, which may block the screen 3 and affect the smaller particles from passing through the screen 3, causing the residue to be unable to be discharged; a technical solution is adopted: the larger particles of residue on the screen 3 can be crushed by the mutual cooperation of the rotating shaft 4, the driving motor 8, the transmission assembly, the rotating shaft 6 and the rolling roller 7; because the implementation process of the technical solution is: the rotating shaft 4 is driven to rotate by the output shaft of the driving motor 8, and then the rotating shaft 6 is driven by the mounting block 5. The screen 3 rotates horizontally, and then drives the rolling roller 7 to rotate around the rotating shaft 4 through the rotating shaft 6. At the same time, the rotating shaft 4 drives the rotating shaft 6 to rotate around itself through the transmission component, and then drives the rolling roller 7 to rotate around itself. Therefore, when the rolling roller 7 rotates on the screen 3, the larger particles of residue on the screen 3 will be crushed into smaller particles of residue. Therefore, the technical problem can definitely be solved, and the technical effect achieved is: it is convenient for the residue to pass through the screen 3, and the residue is prevented from accumulating on the screen 3, which affects the smaller particles of residue from passing through the screen 3, and the residue is convenient to be discharged.

[0033] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
