DETAILED DESCRIPTION

[0025] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0026] The utility model provides Figure 1 - Figure 5 The crystal fluidized state drying device shown in the figure comprises a drying box 1, which is a prior art and will not be described in detail here. A drying plate 2 for carrying crystals is movably provided inside the drying box 1, and a guide rod is fixedly provided on the inner wall of the drying box 1 for carrying the drying plate 2. The guide rod is a prior art and will not be described in detail here. The guide rod is as shown in FIG. Figure 2 As shown, an upper plate 3 is provided at the upper end of the drying plate 2, and baffles 5 are fixedly provided at the upper ends of the drying plate 2 and the upper plate 3. The operator takes out the drying plate 2, and then places the crystals to be dried inside the drying plate 2 through the corresponding side openings of the baffles 5, and puts the drying plate 2 into the drying box 1. Two first conical blocks 201 for gathering crystals are fixedly provided at the upper end of the drying plate 2, and two second conical blocks 4 for dispersing crystals are fixedly provided at the upper end of the upper plate 3;

[0027] By setting the second conical block 4, when the feeding plate 9 takes out the crystal, it can ensure that the crystal that has not been taken out is between the two conical blocks 4, and immediately waits for the feeding plate 9 to take out the crystal next time, ensuring that the crystal taken out is not the crystal that has just entered the drying plate 2;

[0028] A plurality of discharge holes 6 are formed through one end of the second conical block 4, which are mainly used for discharging crystals. A plurality of baffles 8 are fixedly provided inside the discharge holes 6. The number of baffles 8 inside the discharge holes 6 gradually increases from the bottom of the second conical block 4 to the top of the second conical block 4. A feed plate 9 is movably provided between the upper plate 3 and the drying plate 2. Side plates 10 are fixedly provided on both sides of the upper end of the feed plate 9. The feed plate 9 is arranged in an L shape.

[0029] A first electric cylinder 13 is fixedly provided inside the drying box 1, and a second electric cylinder 14 is fixedly provided at the output end of the first electric cylinder 13. When the drying box 1 is opened, the first electric cylinder 13 and the second electric cylinder 14 are controlled to work through the control panel. First, the first electric cylinder 13 works to drive the second electric cylinder 14 to move, and the second electric cylinder 14 drives the feeding plate 9 to move. At this time, the side of the feeding plate 9 away from the second electric cylinder 14 and the side of the intercepting plate 11 are in the same vertical plane. The feeding plate 9 is driven by the second electric cylinder 14 to squeeze the intercepting plate 11 to move, so that the feeding plate The lower end surface of 9 contacts the upper surface of the drying plate 2, and the second electric cylinder 14 works to drive the feeding plate 9 to move away from the second electric cylinder 14, pushing the crystal onto the feeding plate 9, and the first electric cylinder 13 works to drive the second electric cylinder 14 to rise, thereby making the feeding plate 9 drive the crystal to move. The first electric cylinder 13 and the second electric cylinder 14 are both existing technologies and will not be described in detail here. A micro motor 15 is fixedly provided at the output end of the second electric cylinder 14, and the micro motor 15 is a micro servo motor, which will not be described in detail here. The output end of the micro motor 15 is fixedly connected to the end of the feeding plate 9.

[0030] By setting the upper plate 3 and the feeding plate 9, when the crystal is dried, the crystal is moved, the contact between the crystal and the hot air in the drying box 1 is increased, and the heat in the air is fully utilized to dry the crystal, thereby improving the drying efficiency;

[0031] A rectangular groove 7 is formed through one end of the second conical block 4 , and the lower end of the upper plate 3 is fixedly connected to the corresponding end of the baffle 5 .

[0032] By setting the second conical block 4 and the discharge holes 6, the range of crystal movement is increased when the crystal moves, and by setting different numbers of baffles 8, it is ensured that each discharge hole 6 will pass the crystal.

[0033] An intercepting plate 11 is movably provided on the inside of the drying box 1. A rectangular hole is penetrated on one side of the drying plate 2 for the intercepting plate 11 to slide up and down. The upper end of the intercepting plate 11 abuts against the lower end of the feeding plate 9 to ensure that when the feeding plate 9 moves downward, the intercepting plate 11 is driven to move downward. Magnetic blocks 12 are fixedly provided on the end of the intercepting plate 11 and the inner wall of the drying box 1. The two magnetic blocks 12 are in the same vertical plane, and the corresponding sides of the two magnetic blocks 12 repel each other magnetically. The magnetic blocks 12 are commonly used magnets and will not be described in detail here.

[0034] The interception plate 11 uses the mutual repulsive force of the magnetic block 12 to move the feed plate 9. The interception plate 11 is always in close contact with the feed plate 9 to intercept the crystals in the drying plate 2. The second electric cylinder 14 drives the feed plate 9 to move, so that the feed plate 9 moves toward the second electric cylinder 14, so that the feed plate 9 is separated from the drying plate 2. The first electric cylinder 13 drives the second electric cylinder 14 to rise until the height of the feed plate 9 is higher than the height of all the baffles 5. The second electric cylinder 14 drives the feed plate 9 to move toward the baffle 5, so that the feed plate 9 is directly above the upper plate 3. The micro motor 15 works to drive the feed plate 9 to rotate, so that the crystals on the feed plate 9 are poured out.

[0035] The crystal contacts the second conical block 4. The shape of the second conical block 4 allows the crystal to roll toward the lower part of the second conical block 4. The crystal is discharged through a plurality of discharge holes 6 until all the crystals pass through the discharge holes 6 and the rectangular grooves 7 and enter the drying plate 2. The first conical block 201 is provided so that the crystal is accumulated in the middle of the upper end of the drying plate 2, which is convenient for taking out next time.

[0036] The second electric cylinder 14 and the first electric cylinder 13 drive the feeding plate 9 to reset, and thus reciprocate to accelerate the drying of the crystals.
