Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0030] See Figure 1 , Figure 2 , Figure 3 and Figure 4 This utility model provides a high-efficiency drying device for zinc sulfate heptahydrate, comprising:

[0031] Drying box 1 is equipped with a high-efficiency drying mechanism for zinc sulfate heptahydrate. It should be noted that the high-efficiency drying mechanism for zinc sulfate heptahydrate can efficiently and evenly dry zinc sulfate heptahydrate, resulting in good drying effect and improved production efficiency.

[0032] The high-efficiency drying mechanism for zinc sulfate heptahydrate includes a zinc sulfate heptahydrate adding hopper 2, a drying and heat preservation cylinder 4, a vertical rod 6, an agitator blade 7, a power motor 8, a power shaft 9, a gear 10, a gear 2 11, a rotating shaft 13, and a baffle 14.

[0033] The zinc sulfate heptahydrate addition hopper 2 is fixedly installed on the drying oven 1. It should be noted that zinc sulfate heptahydrate is added into the drying and heat preservation cylinder 4 through the zinc sulfate heptahydrate addition hopper 2.

[0034] The stirring blade 7 is fixedly installed on the upright 6, the power motor 8 is fixedly installed on the top of the drying chamber 1, the output end of the power motor 8 is fixedly connected to the power shaft 9, the gear 10 and the gear 21 are respectively fixedly sleeved on the outside of the power shaft 9 and the drying and heat preservation cylinder 4, the gear 10 and the gear 21 mesh with each other, the bottom of the rotating shaft 13 is fixedly connected to the baffle 14, and the baffle 14 seals the bottom of the drying and heat preservation cylinder 4.

[0035] The aforementioned high-efficiency drying mechanism for zinc sulfate heptahydrate, when activated by the power motor 8, causes the drying and heat preservation cylinder 4 to rotate. With the addition of hot air from below into the drying and heat preservation cylinder 4 and the setting of the stirring blades 7, the zinc sulfate heptahydrate can be dried efficiently. After drying, the rotating shaft 13 drives the baffle 14 to rotate, and then the dried zinc sulfate heptahydrate is discharged from the drying and heat preservation cylinder 4 and then from the drying chamber 1. This efficient and uniform drying process results in good drying performance.

[0036] Specifically, the high-efficiency drying mechanism for zinc sulfate heptahydrate also includes an inner plate 3, an iron disc 12, a connecting disc 15, an electromagnet 16, a positioning rod 17, a positioning rod 2 18, and a spring 19. The drying and heat preservation cylinder 4 is rotatably mounted on the inner plate 3. The iron disc 12 is fixedly mounted on the bottom of the power shaft 9. The connecting disc 15 is fixedly mounted on the top of the rotating shaft 13. The top of the electromagnet 16 is fixedly connected to the positioning rod 17, and the bottom of the electromagnet 16 is fixedly connected to the positioning rod 2 18. The positioning rod 2 18 is engaged with the inner plate 3. The spring 19 is fixedly mounted between the positioning rod 2 18 and the connecting disc 15.

[0037] With the aforementioned high-efficiency drying mechanism for zinc sulfate heptahydrate, when it is necessary to unload the dried zinc sulfate heptahydrate, the electromagnet 16 is activated, which moves the electromagnet 16 upward, causing the positioning rod 18 to move out of the positioning slot 2, and the positioning rod 17 to be engaged in the positioning slot 1 on the iron plate 12. At this time, the power motor 8 is activated, which causes the power shaft 9, iron plate 12, electromagnet 16, connecting plate 15, rotating shaft 13 and baffle 14 to rotate synchronously, causing the baffle 14 to be moved away from the bottom of the drying and heat preservation cylinder 4, and the dried zinc sulfate heptahydrate is unloaded from the bottom of the drying and heat preservation cylinder 4.

[0038] Specifically, the bottom of the iron plate 12 has two positioning grooves, and the positioning rod 17 is located directly below the positioning groove. The top of the inner plate 3 has two positioning grooves, and the positioning rod 18 is engaged with the positioning groove. It should be noted that this is to facilitate docking.

[0039] Specifically, two hot air holes are opened at the bottom of the baffle 14. A three-way hot air pipe 20 is fixedly installed inside the hot air holes. A perforated plate is fixedly installed at the top of the three-way hot air pipe 20. A high-temperature resistant hose is fixedly installed at the rear of the three-way hot air pipe 20. The high-temperature resistant hose is fixedly installed on the drying chamber 1. A top frame 5 is fixedly installed on the top of the drying chamber 1. A vertical rod 6 is fixedly installed on the top frame 5. The bottom of the vertical rod 6 passes through the zinc sulfate heptahydrate addition hopper 2 and extends into the drying insulation cylinder 4. The bottom of the zinc sulfate heptahydrate addition hopper 2 extends into the drying insulation cylinder 4. The inside of the zinc sulfate heptahydrate addition hopper 2 is in contact with the drying insulation cylinder 4. It should be noted that the high-temperature resistant hose is connected to an external hot air blower. Hot air is introduced through the three-way hot air pipe 20. The hot air enters the drying insulation cylinder 4 to dry the zinc sulfate heptahydrate inside the drying insulation cylinder 4. The hot air flows in the drying insulation cylinder 4 and is discharged through the zinc sulfate heptahydrate addition hopper 2. The perforated plate (not shown in the figure) can prevent zinc sulfate heptahydrate from entering the three-way hot air pipe 20.

[0040] Specifically, the top of the connecting plate 15 has two stabilizing sliding holes, and the second positioning rod 18 is slidably installed in the stabilizing sliding holes. It should be noted that this allows the second positioning rod 18 to move stably in the vertical direction.

[0041] Working principle:

[0042] S1: Start the power motor 8, which drives the power shaft 9 to rotate. The power shaft 9 drives the gear 10 to rotate, which in turn drives the gear 11 to rotate. The gear 11 drives the drying and heat preservation cylinder 4 to rotate, which in turn drives the zinc sulfate heptahydrate inside the drying and heat preservation cylinder 4 to rotate. With the addition of hot air from below into the drying and heat preservation cylinder 4 and the setting of the agitator 7, the zinc sulfate heptahydrate can be dried efficiently. After drying, the rotating shaft 13 drives the baffle 14 to rotate, and then the dried zinc sulfate heptahydrate is discharged from the drying and heat preservation cylinder 4 and then from the drying box 1. This process can efficiently and evenly dry the zinc sulfate heptahydrate, resulting in good drying effect and improved production efficiency.

[0043] S2: When it is necessary to feed the dried zinc sulfate heptahydrate, start the electromagnet 16. The iron plate 12 above will attract the electromagnet 16, which will cause the electromagnet 16 to move upward. The electromagnet 16 will drive the positioning rod 17 and positioning rod 2 18 to move. The positioning rod 2 18 will squeeze the spring 19, causing the positioning rod 2 18 to move out of the positioning groove 2, and the positioning rod 17 can be inserted into the positioning groove 1 on the iron plate 12.

[0044] S3: At this time, start the power motor 8, which can make the power shaft 9, iron plate 12, electromagnet 16, connecting plate 15, rotating shaft 13 and baffle 14 rotate synchronously, so that the baffle 14 moves away from the bottom of the drying and heat preservation cylinder 4, and the dried zinc sulfate heptahydrate is discharged from the bottom of the drying and heat preservation cylinder 4. After the discharge is completed, the baffle 14 returns to its position, and then the electromagnet 16 is turned off. The electromagnet 16 returns to its position, so that the second positioning rod 18 is re-engaged into the second positioning groove, and the first positioning rod 17 moves away from the first positioning groove. At this time, when the power shaft 9 rotates, the rotating shaft 13 below does not rotate synchronously, which makes the switching more convenient.

[0045] The above provides a detailed description of the high-efficiency drying device for zinc sulfate heptahydrate provided by this utility model. Specific embodiments have been used to illustrate the principle and implementation of this utility model. The descriptions of the embodiments above are only for the purpose of helping to understand the method and core idea of ​​this utility model.
