[0011] The following is a further detailed description of the specific implementation of the present invention in conjunction with the accompanying drawings and examples. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0012] like Figure 1 As shown, a high-efficiency filter press for graphite purification comprises a filter press box 1, wherein the filter press box 1 comprises a filter press inner cylinder 2 and an annular outer cylinder 3 distributed around the outer side thereof, the top of the filter press inner cylinder 2 is a feed port 21, a cylinder 1 4 is fixedly installed above the feed port 21, a cylinder rod 41 of the cylinder 1 4 is vertically downwardly connected to a pressure plate 42 adapted to be embedded in the feed port 21, a T-shaped filter press plate 5 that can slide up and down and a horizontally fixed plate 6 are adapted to be installed in the filter press inner cylinder 2, and the lower end of the T-shaped filter press plate 5 is adapted to pass through the fixed plate 6; a cylinder 2 7 is installed at the bottom of the filter press inner cylinder 3, a cylinder rod 71 of the cylinder 2 7 is vertically upwardly adapted to be embedded in the lower end of the T-shaped filter press plate 5, an adaptation groove 51 adapted to the cylinder rod 71 is opened at the lower end of the T-shaped filter press plate 5, and a spring 8 is adapted to be installed between the bottom of the adaptation groove 51 and the cylinder rod 71.

[0013] like Figure 1As shown, the first filter holes 22 are evenly opened on the side wall of the filter press inner cylinder 2 at a position between the upper end of the T-shaped filter press plate 5 and the fixed plate 6, and the matching annular filter plates 11 and collecting plates 12 are sequentially spaced downwardly between the filter press inner cylinder 2 and the annular outer cylinder 3 at a position below the first filter holes 22, and the filter plates 11 are evenly opened with second filter holes 111 with a pore size smaller than the first filter holes 22, and the side wall of the annular outer cylinder 3 is opened with a discharge port 31 connected to the collecting plate 12, and the outside of the filter press box 1 is provided with a collecting box 9 connected to the discharge port 31, and the collecting box 9 is provided with a water filter plate 9.

[0014] In the above structure, graphite water is added to the T-type filter press plate 5 through the feed inlet 21, and then the graphite water is filtered downward by the cooperation of the cylinder 1 4, the pressure plate 42, the T-type filter press plate 5 and the spring 8. In this process, the filtrate is quickly separated from the filter residue through the first filter hole 22, and then further finely filtered through the second filter hole 111 to reach the collecting plate 12 for automatic collection and then discharged into the collecting box 9 for dehydration to obtain high-purity graphite; in this process, the first filter hole 22 performs coarse filtration and the second filter hole 111 performs fine filtration, which can effectively filter the impurity particles in the graphite water and effectively improve the extraction purity of the graphite; the filter residue after the filter press is retained on the T-type filter press plate 5, and the cylinder 2 7 applies an upward thrust to the T-type filter press plate 5, so that the filter residue on the T-type filter press plate 5 can reach the feed inlet 21, which is convenient for the rapid removal of the filter residue and improves the overall work efficiency.

[0015] Further, if Figure 1 As shown, the collecting plate 12 is an annular inclined surface as a whole, and the discharge port 31 is connected to the lowest point of the collecting plate 12. The collecting plate 12 with an inclined surface can quickly discharge the filtrate from the collecting plate 12 to the collecting box 9. The filter plate 11 is arranged horizontally.

[0016] The working principle of the utility model is as follows: firstly, the graphite material water to be filtered is poured into the T-type filter press plate 5 from the feed inlet 21 at the top of the filter press box 1, and the cylinder 1 4 is opened. The graphite material water is filtered toward the fixed plate 6 through the pressure plate 42, and the filtrate and the filter residue in the graphite material water are separated through the first filter hole 22. The separated filtrate reaches the filter plate 11, and is further finely filtered through the second filter hole 111 before reaching the collecting plate 12, and then is discharged from the discharge port 31 into the collecting box 9, and high-purity graphite can be obtained after the water removal treatment of the filter water plate 91; then, an upward thrust is applied to the T-type filter press plate 5 through the cylinder 2 7, so that the filter residue on the T-type filter press plate 5 after the filter is filtered can reach the feed inlet 21 and be taken out. This process greatly improves the working efficiency of the entire filter press process and the purity of graphite extraction.

[0017] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the technical principles of the present invention. These improvements and modifications of the above assumptions should also be regarded as the protection scope of the present invention.
