DETAILED DESCRIPTION
[0030] Specific implementation one: combine Figure 1 , Figure 2The embodiment is described as follows. The embodiment comprises a reaction kettle 1, a filter screen 2, a sealing cover 3 and a driving member 4. The reaction kettle 1 has a preparation cavity 5 with an opening facing upward. The filter screen 2 is slidingly installed in the preparation cavity 5. The driving end of the driving member 4 is connected with the filter screen 2. The driving member 4 is used to drive the filter screen 2 to reciprocatingly move up and down. The sealing cover 3 is placed at the opening of the preparation cavity 5. The filter screen 2 has filter holes 6 which can be switched between an open state and a closed state. When the fly ash microbeads are subjected to pickling, the filter holes 6 are in the closed state. When the fly ash microbeads and the phase change material are mixed, the filter holes 6 are switched from the open state to the closed state. The application range is wide. The solid and liquid phase change materials can be used for mixing. The use amount of the phase change material is small. When pickling, the acid solution can be added into the reaction kettle 1.
[0031] The filling preparation device of the fly ash phase change microbeads of the embodiment is used to pickle the fly ash microbeads on the filter screen 2. The filter holes 6 are opened. The filter holes 6 can filter the fly ash microbeads and screen out qualified products. Then, the filter holes 6 are closed. The phase change material is placed into the preparation cavity 5. Under the pushing of the driving member 4, the phase change material and the fly ash microbeads reciprocatingly move up and down, so that the mixing is completed. The phase change material does not need to fill the moving space of the fly ash microbeads. The use amount is greatly reduced. In turn, the preparation cost is reduced.
[0032] Specific implementation method two: combined with Figure 2 , Figure 3 The embodiment is described as follows. The embodiment is different from the specific implementation method one in that the filter screen 2 comprises relatively rotatable upper filter plates 7 and lower filter plates 8. The filter holes 6 are arranged on the upper filter plates 7 and the lower filter plates 8 in a rectangular array mode. The relative rotation of the upper filter plates 7 and the lower filter plates 8 is controlled to switch the open state and the closed state of the filter holes 6. When the filter holes 6 on the upper filter plates 7 are all aligned with the filter holes 6 on the lower filter plates 8, the filter holes 6 are in the open state and are used for screening. The upper filter plates 7 or the lower filter plates 8 are rotated to cause the misalignment of the two parts of the filter holes 6. The filter holes 6 on one filter plate are sealed by the other filter plate. The filter holes 6 are in the closed state and are used for mixing. The other components and connection relationship are the same as those of the specific implementation method one.
[0033] Specific implementation method three: combined with Figure 2 , Figure 3The difference between the embodiment and the second specific embodiment is that one of the upper filter plate 7 and the lower filter plate 8 has a clamping groove 9, and the other is connected with a clamping block 10 matched with the clamping groove 9. The shapes of the clamping groove 9 and the clamping block 10 are the same. In the embodiment, the clamping groove 9 is located on the lower filter plate 8, and the clamping block 10 is located on the upper filter plate 7. The relative rotation of the upper filter plate 7 and the lower filter plate 8 is realized through the cooperation of the clamping groove 9 and the clamping block 10, so as to switch the state of the filter hole 6. Of course, the clamping groove 9 can also be arranged on the upper filter plate 7, and the clamping block 10 can be arranged on the lower filter plate 8. The other components and connection relationships are the same as those in the second specific embodiment.
[0034] The fourth specific embodiment is combined with the third specific embodiment. Figure 7 、 Figure 8 The difference between the embodiment and the third specific embodiment is that the clamping block 10 includes a fixedly connected vertical plate 11 and a horizontal plate 12. The vertical plate 11 and the horizontal plate 12 are arc-shaped plates or blocks extending in the circumferential direction. The vertical plate 11 plays a guiding role, so that the upper filter plate 7 and the lower filter plate 8 can rotate relative to each other. The horizontal plate 12 plays a limiting role, preventing the upper filter plate 7 and the lower filter plate 8 from being separated, so that the upper filter plate 7 and the lower filter plate 8 form an integral whole and can still rotate relative to each other. The structure is not loose when moving up and down, the connection is tight, and the vertical plate 11 and the horizontal plate 12 are integrally formed. The other components and connection relationships are the same as those in the third specific embodiment.
[0035] The fifth specific embodiment is combined with the second specific embodiment.

A polygonal column 15 that can slide up and down is arranged in the polygonal hole 14. When the filter hole 6 is in the open state, the bottom end of the polygonal column 15 is inserted into the polygonal groove 13. The inner wall of the polygonal hole 14 has a limiting groove 16. A limiting plate 17 connected to the polygonal column 15 extends into the limiting groove 16. An elastic element 18 is arranged between the limiting plate 17 and the top wall of the limiting groove 16. The elastic element 18 has a pushing force that moves the polygonal column 15 downward. In the embodiment, the polygon is a rectangle, which is not limiting. It can also be a triangle, a hexagon, or other shapes. The relative rotation of the upper filter plate 7 and the lower filter plate 8 is controlled by the polygonal column 15, so as to switch the state of the filter hole 6. The elastic element 18 can offset the inertial force when moving up and down. When mixing, the polygonal column 15 is always inserted into the polygonal groove 13, and the upper filter plate 7 and the lower filter plate 8 do not rotate, so as to ensure that the filter hole 6 is in the closed state. The other components and connection relationships are the same as those in the second specific embodiment.

Of course, the elastic member 18 can also be a spring, one end of which is connected with the top wall of the limiting groove 16, and the other end of which is connected with the limiting plate 17. The other components and connection relationships are the same as those in the fifth specific embodiment.

The higher the rotation speed of the motor is, the faster the filter screen 2 moves up and down, and the better the mixing effect is. Of course, the driving member 4 can also be a hydraulic cylinder or a pneumatic cylinder or an electric telescopic rod. The other components and connection relationships are the same as those in the first specific embodiment.
[0038] The eighth specific embodiment is described. Figure 2 The embodiment is described. The embodiment is different from the seventh specific embodiment in that it further comprises a sealing sleeve 24 connected between the filter screen 2 and the bottom wall of the preparation cavity 5 and sleeved outside the transmission rod 22.
