[0002] In the early stage of sugarcane processing, it needs to be squeezed and filtered. After squeezing, filtering the sugarcane juice is an indispensable step in the sugarcane sugar industry. The sugarcane juice obtained by squeezing sugarcane often contains insoluble solid impurities such as pectin and cellulose, which need to be removed by filtering.

[0003] The existing sugarcane juice filtering device generally uses a plate and frame filter press to perform the sugarcane filtering operation, and squeezes the sugarcane juice in the filter screen by pressure at both ends. This filtering method is relatively simple, and the filtering is achieved by a single squeezing method. When the squeezing reaches a certain degree, the solid residue is evenly stressed, and the juice remaining inside cannot be squeezed out, resulting in incomplete filtering and loss, thereby reducing the use value of the juice filtering device.

[0047] A method for filtering sugarcane juice, using the device for filtering sugarcane juice as described above, comprises the following steps:

[0048] Step 1: The crushed sugar cane is introduced into the liquid passing frame 401, and then the hydraulic cylinders 406 are adjusted to drive the pressing plate 404 to squeeze the sugar cane in the liquid passing frame 401, and the juice in the sugar cane flows into the juice collecting cover 3 along the liquid holes on the liquid passing frame 401. After the hydraulic cylinders 406 are adjusted repeatedly for many times, the driving motor 405 is started, and the driving motor 405 drives the dispersing teeth 403 to disperse the sugar cane in the liquid passing frame 401, so that the sugar cane is rearranged, and then the hydraulic cylinders 406 are adjusted again to drive the pressing plate 404 to squeeze the sugar cane, and the process is repeated for many times, thereby completing the operation of squeezing the sugar cane.

[0049] Step 2: After the juice is squeezed, the infusion pump 14 is started, and the infusion pump 14 introduces the sugarcane juice into the rotating hollow column 1701 through the infusion tube 5, and enters the filter cartridge 10 through the feeding hole 1710, and then the hydraulic cylinder 3 1706 is adjusted to drive the lifting plate 1704 to perform preliminary filtering on the juice;

[0050] Step 3: After the initial filtration, the solid impurities remaining in the juice are accumulated at the bottom, and the cylinder 1 1714 is adjusted to drive the linkage column 1715 to press down, so that each ejection scraper 1712 is ejected for a distance, and the ejection scraper 1712 is inserted into the solid impurities, and the drive motor 2 1703 is started, and the drive motor 2 1703 drives each ejection scraper 1712 to rotate, and the accumulated solid impurities are squeezed on the horizontal plane, so that the accumulated solid impurities are subjected to secondary filtration. When the drive motor 2 1703 drives the ejection scraper 1712 to rotate for multiple circles, the ejection scraper 1712 is rotated for multiple circles. After the rotation, turn off the driving motor 2 1703, and adjust the hydraulic cylinder 4 1711 to drive each squeezing column 1705 to squeeze the upper end surface of the accumulated solid impurities. After the squeezing column 1705 repeatedly squeezes for many times, the squeezing column 1705 resets, and then the driving motor 2 1703 is started again to drive the squeezing column 1705 to rotate 15°, and the squeezing column 1705 is pushed out again. The driving motor 2 1703 is repeatedly turned on and off 24 times to achieve all-round single-point squeezing of the accumulated solid impurities. The sugarcane juice at the filter press is introduced into the collecting frame 11 through the filter cartridge 10, and the operation is ended.
