The output end of the motor 17 is connected to the top of the fixing block 23. Figure 2 and Figure 5 As shown, the grinding pestle 14 is a bulb-shaped structure, wherein the stirring turbine 16 is fixedly connected to the upper curved surface, a placement cavity 15 is provided inside the grinding pestle 14, and the fixing block 23 is an inverted nail-shaped structure. The grinding pestle 14 is fixedly connected to the fixing block 23 by bolts, and the diameter of the spherical bottom of the grinding pestle 14 is less than or equal to the diameter of the inside of the mixing drum 12; Figure 3 As shown, a thread is arranged on the bottom curved surface of the mixing drum 12, and a threaded hole with the same diameter as the bottom of the mixing drum 12 is opened on the top of the filter press 13, and the filter press 13 is threadedly connected to the mixing drum 12 through the threaded hole.

[0026] The working principle is as follows: a plurality of support frames 11 are fixedly connected above the bottom plate 10, and the plurality of support frames 11 support the mixing drum 12. According to the type of cellulose to be filtered, a heating tube or ice cubes, or even other objects for auxiliary reaction, can be placed in the placement cavity 15, the fixing block 23 is connected to the grinding pestle 14, and then the fixing plate 24 is connected to the mixing drum 12, and the motor 17 is started to drive the grinding pestle 14 to rotate. Since the Y-shaped through-cavities of the grinding pestle 14 and the mixing drum 12 are similar in shape, the cellulose will pass through the gap between the two during rotation, and the large particles will be ground to ensure the loose uniformity, and then the stirring turbine 16 will rotate with the rotation of the grinding pestle 14 for stirring.

The slider 19 slides in the slot and is clamped through the slot; Figure 4 and Figure 5 As shown, one side of the slide buckle 19 is fixedly connected to the limiting column 20, and the limiting column 20 is located at the hook head of the slide buckle 19.
