Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0022] See also Figure 1-4 As shown, a precipitation separation device for silicon removal includes a base 1 and a pretreatment shell 2 fixed to one side of the top of the base 1. A water inlet shell 3 is provided on one side of the top of the pretreatment shell 2. The pretreatment shell 2 cooperates with the water inlet shell 3 to facilitate the drainage of liquid containing silicon bodies and sewage, and also facilitates the pouring of purification media such as precipitants. A precipitation shell 4 is fixedly connected to the top of the base 1. The precipitation shell 4 cooperates with the drainage shell 5 to facilitate the diversion of the mixed liquid into the precipitation shell 4 for precipitation and diversion. One side of the precipitation shell 4 is directly connected to the pretreatment shell 2 via the drainage shell 5.

[0023] A purification shell 6 is fixed to one side of the top of the base 1, and one side of the purification shell 6 is connected to the sedimentation shell 4. One side of the purification shell 6 is connected to a drain pipe 7, through which the finally separated liquid can be discharged through the drain pipe 7. The bottom of the sedimentation shell 4 is connected to a sewage pipe 8, and a sewage pump 9 is installed on the surface of the sewage pipe 8. The sewage pump 9 cooperates with the sewage pipe 8 to conveniently extract the silicon and impurities precipitated in the sedimentation shell 4. The top of the sewage pump 9 is fixedly connected to the base 1, and the top of the pretreatment shell 2 is fixedly connected to a driving component 10 for stirring, and the driving component 10 includes a motor 1001.

[0024] The motor 1001 is fixed to the top of the pretreatment shell 2. The output end of the motor 1001 passes through the interior of the pretreatment shell 2 and is installed with a transmission rod 1002. The surface of the transmission rod 1002 is fixedly connected with a stirring blade 1003. By turning on the motor 1001, the transmission rod 1002 can be rotated. At this time, the transmission rod 1002 will drive the stirring blade 1003 to stir the sewage containing the silicon medium, and the precipitant and purifier are poured into the water inlet shell 3 for mixing. The surface of the transmission rod 1002 is fixedly connected with an extension rod 1004, and one side of the extension rod 1004 is fixedly connected with a scraper 1005.

[0025] A filter shell 11 is provided inside the drainage shell 5. The front side of the drainage shell 5 is fixedly connected to a first clip 12 used in conjunction with the filter shell 11. The impurities in the sewage can be filtered in advance through the filter shell 11, and the first clip 12 facilitates the disassembly and cleaning of the filter shell 11. The first clip 12 is a simple plug-in plate and rod structure. A guide plate 13 is fixedly connected to one side of the drainage shell 5. The guide plate 13 can prevent the water flow from being too large and the possibility of being discharged directly into the purification shell 6 without sedimentation. A baffle 14 is hinged on one side of the top of the water inlet shell 3.

[0026] Partitions 15 are provided on the front and rear sides of the purification shell 6, which facilitate the support of the leakage shell 16 through the partition 15, and the leakage shell 16 facilitates secondary filtration of the precipitated water, thereby improving the separation and purification effect. A leakage shell 16 for storing the purification medium is provided on the top of the partition 15. A second clip 17 used in conjunction with the leakage shell 16 is fixedly connected to one side of the purification shell 6. The second clip 17 facilitates the removal and replacement of the purification medium from the leakage shell 16, and the second clip 17 has the same principle as the first clip 12. The four corners of the bottom of the base 1 are fixedly connected with support legs 18, which facilitate the support of the base 1 through the support legs 18.

[0027] Working principle: First, the sewage containing silicon medium is poured into the interior of the pretreatment shell 2 through the water inlet shell 3, and the precipitant and purifier can also be introduced at the same time. Then, the transmission rod 1002 can be rotated by turning on the motor 1001. At this time, the transmission rod 1002 will drive the stirring blade 1003 to stir the sewage containing silicon medium. The precipitant and purifier are poured into the water inlet shell 3 to mix. When the transmission rod 1002 rotates, it will also drive the extension rod 1004 to cooperate with the scraper 1005 to clean the inner wall of the pretreatment shell 2 , so that the pretreatment shell 2 is fully mixed, and the precipitant reacts with silicon to form an insoluble precipitate. The mixed liquid will then pass through the filter shell 11 in the drainage shell 5 to filter out impurities and then overflow into the sedimentation shell 4 for precipitation. When the precipitation reaches a certain water storage volume, the liquid will overflow into the purification shell 6, and the separated liquid will be filtered twice by the purification medium inside the leakage shell 16 and then discharged through the drain pipe 7. Finally, the sewage pump 9 is turned on to extract the medium precipitated at the bottom of the inner cavity of the sedimentation shell 4 through the sewage pipe 8, thereby completing the separation work.
