[0040] Embodiment 1

[0041] like Figure 1-19 As shown, a phthalic anhydride slicing device includes a bracket 1, a roller 5 is rotatably connected to the bracket 1, a material trough 11 is provided between the bracket 1 and the roller 5, a shell is provided outside the roller 5, the shell is fixedly connected to the bracket 1, a knife holder is provided in the shell, the upper end of the knife holder is rotatably connected to a movable plate 22 sliding on the shell, the lower end of the knife holder is slidably connected to a limit rod 25 fixed inside the shell, the movable plate 22 is threadedly connected to a screw rod 20, the screw rod 20 is rotatably connected to a fixed plate 21 fixed to the outer wall of the shell, and a phosphor bronze blade 26 is fixed on the knife holder.

[0042] The working principle of the above technical solution is as follows: phthalic anhydride solution is contained in the material trough 11. When the drum 5 rotates, the phthalic anhydride solution in the material trough 11 adheres to the outer surface of the drum 5. Cooling water is provided inside the drum 5. The cooling water cools the phthalic anhydride solution adhered to the outer surface of the drum 5. The phthalic anhydride solution solidifies rapidly. The blade portion of the phosphor bronze blade 26 is attached to the outer surface of the drum 5. The solidified phthalic anhydride is cut off by the phosphor bronze blade 26. The screw 20 is rotated to drive the movable plate 22 to slide in the shell, drive the upper end of the tool holder to move, drive the lower end of the tool holder to slide with the limit rod 25, and then change the angle between the tool holder and the drum 5, and then change the cutting angle between the phosphor bronze blade 26 and the drum 5 and the distance between the blade portion of the phosphor bronze blade 26 and the drum 5, and then change the thickness of the cut phthalic anhydride, which can be adjusted according to actual production needs.

[0043] Embodiment 2

[0044] like Figure 1-19As shown, the drum 5 includes an outer cylinder 501 and an inner cylinder 502, the outer cylinder 501 is fixedly connected to the inner cylinder 502, a chamber 1 is arranged between the outer cylinder 501 and the inner cylinder 502, a chamber 2 is arranged in the inner cylinder 502, a long groove 503 is arranged on the inner cylinder 502, the chamber 1 and the chamber 2 are connected through the long groove 503, and a water inlet hole 504 is arranged at the connection between the outer cylinder 501 and the inner cylinder 502;

[0045] The outer tube 501 has an inlet pipe 6 inserted at one end, and a check valve 7 is provided inside the inlet pipe 6. The outer tube 501 has an outlet pipe 8 inserted at the other end, and the end of the outlet pipe 8 is inserted into the inner tube 502. A check valve 9 is provided inside the outlet pipe 8. The outlet pipe 8 is fixedly connected to a liquid level detector 10.

[0046] The working principle of the above technical solution is as follows: external cooling water enters the outer cylinder 501 from the water inlet pipe 6, and enters the chamber 1 from the water inlet hole 504. The cooling water cools the outer cylinder 501, and then cools the phthalic anhydride solution, so that the phthalic anhydride solution solidifies rapidly. As the drum 5 rotates continuously and the amount of water in the chamber 1 increases continuously, the water in the chamber 1 overflows into the chamber 2 through the long groove 503. When the liquid level detector 10 detects that the water level rises to a preset height, it starts the water pump connected to the water outlet pipe 8, driving the water in the chamber 2 to be discharged from the water outlet pipe 8.

[0047] The traditional drum 5 is a single-layer, and the cooling water directly enters the drum 5. The space inside the drum 5 is large, and a large amount of cooling water is required to fill and circulate. The cooling water in this scheme can enter the chamber 1 set between the outer cylinder 501 and the inner cylinder 502. The space is relatively small, which can save the amount of cooling water. On the other hand, the same amount of cooling water can contact the outer cylinder 501 in the chamber 1. The area is larger, and the cooling effect is good. After absorbing heat in the chamber 1, the cooling water enters the chamber 2 and is discharged through the outlet pipe 8. The external cooling water continuously enters the chamber 1 through the inlet pipe 6 to replenish the cooling water. The check valve 1 7 can prevent the cooling water from flowing back in the inlet pipe 6, and the check valve 2 9 can prevent the cooling water from flowing back in the outlet pipe 8.

[0048] Embodiment 3

[0049] like Figure 1-19 As shown, the outer cylinder 501 is fixedly connected to the gear 2 4, the gear 2 4 is meshed with the gear 1 3 for transmission, the gear 1 3 is connected to the output end of the drive motor 2, and the drive motor 2 is fixed on the bracket 1;

[0050] The working principle of the above technical solution is: starting the driving motor 2 drives the gear 1 3 to rotate, drives the gear 2 4 to rotate, drives the drum 5 to rotate, the phthalic anhydride solution in the material trough 11 adheres to the outer surface of the drum 5, and the chamber 1 arranged between the outer cylinder 501 and the inner cylinder 502 is provided with cooling water. The cooling water cools the phthalic anhydride solution attached to the outer surface of the drum 5, and the phthalic anhydride solution solidifies quickly. The phosphor bronze blade 26 cuts off the solidified phthalic anhydride.

[0051] Embodiment 4

[0052] like Figure 1-19 As shown, a slide bar 12 is fixed on the material trough 11, and the slide bar 12 is slidably connected with a scraper 13. A spring 14 is provided between the end of the slide bar 12 and the scraper 13. The spring 14 presses the front end of the scraper 13 against the side of the outer cylinder 501. The material trough 11 is rotatably connected with a screw 15, and the screw 15 is threadedly connected with a scraper 16. The scraper 16 is slidably connected with the side wall of the material trough 11, and the material trough 11 is fixedly connected with the feed pipe 64.

[0053] The working principle of the above technical solution is as follows: scrapers 13 are provided on both sides of the outer cylinder 501, and a spring 14 pushes the front end of the scraper 13 against the side of the outer cylinder 501. As the outer cylinder 501 rotates, phthalic anhydride solution will also adhere to both sides of the outer cylinder 501. The scraper 13 can scrape the phthalic anhydride from the side of the outer cylinder 501 to prevent the phthalic anhydride from continuously adhering to both sides of the outer cylinder 501, causing waste of phthalic anhydride.

[0054] The front end of the scraper 2 16 maintains a preset distance from the outer surface of the outer cylinder 501, thereby ensuring the thickness of the phthalic anhydride attached. The excess phthalic anhydride is scraped off by the scraper 2 16, and the screw 15 is rotated to drive the scraper 2 16 to move forward or backward, thereby changing the distance between the front end of the scraper 2 16 and the outer surface of the outer cylinder 501, thereby changing the thickness of the phthalic anhydride that can be attached.

[0055] The material can be added or discharged into the material tank 11 through the feed pipe 64.

[0061] The lower shell 17 and the upper shell 18 form a relatively closed space, which can keep the temperature inside constant and prevent the phthalic anhydride solution in the material tank 11 from solidifying before adhering to the outer surface of the outer cylinder 501.

As the outer cylinder 501 rotates, because the horizontal knife 30 and the vertical knife 31 are pressed tightly against the outer cylinder 501, the rotating rod 29, the horizontal knife 30 and the vertical knife 31 are driven to rotate as a whole, and the rotating rod 29 and the slider 27 are driven to rotate, and then the multiple horizontal knives 30 and the multiple vertical knives 31 are driven to continuously cut the phthalic anhydride on the surface of the outer cylinder 501.
