[0012] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0013] Please see Figure 1-2This utility model discloses a filtration device for sugar production, comprising a cylindrical body 1, a filter cylinder 2, and a drive mechanism for rotating the filter cylinder 2. The upper end of the cylindrical body 1 is open, and a discharge port 1.1 is provided on the lower side wall of the cylindrical body 1. The filter cylinder 2 is disposed inside the cylindrical body 1, and the diameter of the filter cylinder 2 is smaller than the inner diameter of the cylindrical body 1. There is a gap between the filter cylinder 2 and the cylindrical body 1. The wall of the filter cylinder 2 is provided with multiple filter holes 2.1. The upper end of the filter cylinder 2 is sealed and rotates at the opening at the upper end of the cylindrical body 1. A bearing 4 and a feed pipe 3 are provided in the middle of the upper end of the filter cylinder 2, and the inner ring of the bearing 4 is sleeved on the outer ring of the feed pipe 3. On the wall, the outer ring of bearing 4 is fixed to the upper end of filter cylinder 2. Feed pipe 3 is vertically arranged and its lower end penetrates into filter cylinder 2. The upper end of feed pipe 3 is fixedly connected to feed device, and the lower end of feed pipe 3 extends into filter cylinder 2. Scraper 5 is connected to the outer wall of the lower end of feed pipe 3. Scraper 5 is connected to feed pipe 3 through a transverse connecting rod. Scraper 5 extends along the inner wall of cylinder 1 and fits against the inner wall of filter cylinder 2 to scrape off filter residue on the cylinder wall of filter cylinder 2. The lower end of filter cylinder 2 rotates on the bottom plate of cylinder 1. A discharge port and control valve 10 are provided at the lower end of filter cylinder 2. The drive mechanism includes motor 8, drive wheel 9, driven wheel 6 and conveyor belt 7. Motor 8 is located on the outer wall of cylinder 1. The output shaft of motor 8 is connected to drive wheel 9. Driven wheel 6 is sleeved on the outside of feed pipe 3 through central shaft hole and connected to the outer ring of bearing 4. Conveyor belt 7 is sleeved on drive wheel 9 and driven wheel 6.

[0014] In a specific implementation of this utility model, the central axes of the filter cylinder 2 and the cylinder body 1 coincide. The feed pipe 3 at the upper end of the filter cylinder 2 is fixed. Driven by the drive mechanism, the filter cylinder 2 rotates outside the feed pipe 3. The diameter of the central shaft hole of the driven wheel 6 is larger than the diameter of the feed pipe 3. When the driven wheel 6 rotates, it drives the outer ring of the bearing 4 to rotate. The lower part of the filter cylinder 2 is conical. The bottom plate of the cylinder body 1 is high in the middle and low on both sides. The discharge port 1.1 is located on the side wall of the cylinder body 1 at the lower end of the bottom plate. A bearing seat is provided in the middle of the bottom plate of the cylinder body 1, and a bearing is installed in the bearing seat. The lower end of the filter cylinder 2 rotates in the bearing seat through the bearing. The bottom plate of the cylinder body 1 is connected to the periphery of the bearing seat. A protruding platform is provided on the inner wall of the upper end of the cylinder 1. An extension plate corresponding to the protruding platform is provided at the upper end of the filter cylinder 2, that is, the upper part of the filter cylinder 2 is T-shaped. A steel ball 11 is provided on the protruding platform. The steel ball 11 is embedded in the groove of the protruding platform. The extension plate of the filter cylinder 2 rotates on the protruding platform through the steel ball 11. The end face of the extension plate facing the protruding platform is also provided with a groove corresponding to the steel ball 11.

[0015] In operation, material enters the filter cylinder through the feed pipe. Initially, the control valve at the lower end of the filter cylinder is closed. Once a certain material level is reached, feeding stops, and the drive mechanism rotates the filter cylinder. Under centrifugal force, the material in the filter cylinder passes through the filter holes in the cylinder wall for filtration. The filtrate enters between the filter cylinder and the cylinder body and exits through the discharge port. Filtration residue remains on the filter cylinder wall. As the filter cylinder rotates, a scraper connected to the feed pipe scrapes off the filtration residue from the filter cylinder wall. The control valve at the lower end of the filter cylinder is then opened for discharge. This invention utilizes centrifugal force for filtration, and the filtration residue can be scraped off by the scraper, facilitating cleaning and maintenance and improving work efficiency.
