The filtered cleaning liquid returns to the tank body 1 through the first return pipe 8, so as to realize the recycling of the cleaning liquid. The second booster pump increases the liquid pressure in the first delivery pipe 7 so that the cleaning liquid passes smoothly. A cooling chamber 9 is provided inside the tank body 1, and a cooling box 10 is provided on the outside of the tank body 1 corresponding to the filter component 6. The cooling box 10 is connected to the cooling chamber 9 through the second delivery pipe 11 and the second return pipe 12. A third booster pump is provided inside the second delivery pipe 11. The third booster pump increases the gas flow rate in the second delivery pipe 11, and the high-speed airflow returns to the cooling chamber 9 through the cooling box 10 and the second return pipe 12 in turn.

[0021] like Figure 1 As shown, a fixing plate 13 is fixedly installed on the outer surface of the tank body 1, and a plurality of support rods 14 are fixedly installed on the bottom surface of the fixing plate 13. The plurality of support rods 14 are distributed circumferentially about the center line of the fixing plate 13.

The plurality of support rods 14 jointly support the tank body 1 to form a stable supporting structure, which effectively resists the influence of external factors on the tank body 1 and ensures the stability of the reactor during operation. The circumferential distribution of the support rods 14 can evenly disperse the weight and pressure generated by the tank body 1 and the materials therein, and prevent structural deformation or damage caused by excessive local force.

[0022] like Figure 3As shown, the discharging assembly 5 includes a conical tube 501, which corresponds to the inner wall of the tank body 1, and a ring plate 502 is fixedly installed on the inner wall of the conical tube 501. A conveying groove 503 is opened inside the ring plate 502, and a plurality of injection holes 504 connected with the conveying groove 503 are opened on the bottom surface of the ring plate 502 corresponding to the conveying groove 503.

A discharge pipe 508 is fixedly installed on the bottom surface of the conical tube 501. A first valve is arranged inside the discharge pipe 508, and a second valve is arranged inside the connecting pipe 505. When the material in the tank body 1 is discharged, the second valve is closed and the first valve is opened, so that the material can smoothly leave the equipment through the discharge pipe 508. When the discharge component 5 is cleaning the inside, the first valve is closed and the second valve is opened, and the cleaning liquid enters the connecting pipe 505 through one end of the connecting pipe 505. The first booster pump 507 increases the liquid pressure in the connecting pipe 505, so that the high-pressure cleaning liquid enters the conveying groove 503. Since the injection hole 504 is conical, the high-pressure liquid in the conveying groove 503 impacts the inner wall of the conical tube 501 through the injection hole 504, thereby completing the cleaning of the inner wall of the conical tube 501.

[0023] like Figure 4-6 As shown, the filter assembly 6 includes a filter box 601, and a plurality of slide grooves 602 are opened inside the filter box 601, and the plurality of slide grooves 602 are linearly distributed along the edge direction of the filter box 601. A return plate 603 is fixedly installed on the inner wall of the filter box 601 corresponding to the slide groove 602, and a frame 604 is arranged inside the slide groove 602 corresponding to the return plate 603, and a filter plate 605 corresponding to the return plate 603 is arranged inside the frame 604. The return plate 603 corresponds to the filter plate 605, and the filter plate 605 filters the clean liquid passing through the filter box 601, and the slide groove 602 facilitates the frame 604 to drive the filter plate 605 to leave the equipment.

[0024] like Figure 5As shown, a fixed groove 606 is provided on the upper surface of the frame 604, and a sliding groove 607 is provided inside the frame 604 corresponding to the fixed groove 606. The sliding groove 607 is connected to the fixed groove 606 through a plurality of connecting grooves 608, and the plurality of connecting grooves 608 are symmetrically distributed about the center line of the fixed groove 606. A moving plate 609 is provided inside the sliding groove 607, and a top rod 610 corresponding to the connecting groove 608 is fixedly installed on the upper surface of the moving plate 609, and two lifting plates 611 are fixedly installed on the bottom surface of the moving plate 609. The lifting plates 611 are all in contact with the inner wall of the sliding groove 607, and a push plate 612 is arranged below the lifting plate 611. A top plate 613 corresponding to the lifting plate 611 is fixedly installed on the upper surface of the push plate 612. The top plate 613 and the lifting plate 611 are both provided with rounded corners on the side close to each other, and the rounded corners of the top plate 613 and the lifting plate 611 are in contact with each other. When the staff pushes the push plate 612, the top plate 613 on the push plate 612 pushes the lifting plate 611 along the direction of the rounded corner edge line during the movement of the push plate 612, thereby moving the movable plate 609.

[0025] like Figure 6 As shown, a movable groove 614 corresponding to the fixed groove 606 is provided inside the return plate 603, and a plurality of guide rods 615 are fixedly installed on the top of the inner wall of the movable groove 614. The plurality of guide rods 615 are symmetrically distributed about the center line of the return plate 603. A limit plate 616 corresponding to the movable groove 614 is provided inside the fixed groove 606. The outer surfaces of the plurality of guide rods 615 are sleeved with springs 617. The two ends of the spring 617 are fixedly connected to the inner wall of the movable groove 614 and the surface of the limit plate 616 respectively. When the filter plate 605 is fixed , the spring 617 pushes the limit plate 616 into the fixed groove 606, so that the frame 604 is fixed in the slide groove 602. When the equipment is maintained, the push rod 610 pushes the limit plate 616 out of the fixed groove 606 when the movable plate 609 moves upward, so that the frame 604 can slide in the slide groove 602. A rounded corner is set on the side of the frame 604 away from the push plate 612. When the frame 604 with the filter plate 605 is installed, the rounded corner facilitates the movement of the limit plate 616, thereby facilitating the frame 604 to enter the slide groove 602.

[0026] like Figure 7 As shown, a plurality of first cooling plates 15 and a plurality of second cooling plates 16 are fixedly installed on the inner wall of the cooling box 10, and the plurality of first cooling plates 15 and the plurality of second cooling plates 16 are spaced apart along the sideline direction of the cooling box 10. Both the first cooling plates 15 and the second cooling plates 16 are made of semiconductors, and the spaced apart distribution is used to extend the moving distance of the gas in the cooling box 10. At the same time, this distribution method increases the contact area between the gas and the first cooling plates 15 and the second cooling plates 16, thereby improving the efficiency and uniformity of cooling.

[0027] like Figure 1As shown, a first feed pipe 17 is fixedly installed on the upper surface of the tank body 1. The first feed pipe 17 is connected to the tank body 1. The first feed pipe 17 serves as the main channel for materials to enter the tank body 1, ensuring that various raw materials, catalysts or solvents required for the reaction can be smoothly and accurately added into the tank body 1.

[0028] like Figure 8 As shown, a second feed pipe 18 is fixedly installed on the outer surface of the second delivery pipe 11, and a one-way valve 19 is arranged inside the second feed pipe 18. The second delivery pipe 11 is connected to the outside through the second feed pipe 18. When the temperature in the cooling chamber 9 is lowered, the internal air pressure becomes low, and the external gas pushes the one-way valve 19 to enter the second delivery pipe 11, thereby balancing the air pressure in the cooling chamber 9 and reducing the probability of equipment damage.

[0029] like Figure 2 As shown, a plurality of stirring blades 20 are fixedly mounted on the outer surface of the rotating shaft 2, and the plurality of stirring blades 20 are distributed circumferentially about the outer surface of the rotating shaft 2, and the scraper 3 is fixedly connected to the corresponding stirring blades 20 via a second connecting plate 21. The rotating shaft 2 drives the stirring blades 20 to stir the material in the tank body 1, and at the same time, the stirring blades 20 drive the scraper 3 to move via the second connecting plate 21, thereby ensuring that the scraper 3 cleans the inner wall of the tank body 1 in real time, and at the same time, the stability of the scraper 3 can be further improved.

[0030] Working principle: When processing materials, the materials enter the tank body 1 through the first feeding pipe 17, the rotating shaft 2 drives the stirring blade 20 to rotate, and the first connecting rod and the second connecting rod drive the scraper 3 to clean the inner wall of the tank body 1. At the same time, the third booster pump increases the gas flow rate in the second conveying pipe 11, and the high-speed airflow returns to the cooling chamber 9 through the cooling box 10 and the second return pipe 12 in turn. The first cooling plate 15 and the second cooling plate 16 in the cooling box 10 cool the gas passing through the cooling box 10, so that the cooling chamber 9 cools the material in the tank body 1. When the temperature in the cooling chamber 9 is reduced, The internal air pressure becomes low, and the external gas pushes the one-way valve 19 into the second conveying pipe 11, thereby balancing the air pressure in the cooling chamber 9. After the material processing is completed, the second valve in the connecting pipe 505 is closed, and the first valve in the discharge pipe 508 is opened, so that the material can smoothly leave the equipment through the discharge pipe 508; when cleaning the tank body 1, the cleaning liquid enters the tank body 1 through the first feed pipe 17, the first valve is closed, and the second valve is opened. The cleaning liquid cannot pass through one end of the connecting pipe 505 and enters the connecting pipe 505. The first booster pump 507 increases the liquid pressure in the connecting pipe 505, so that the high-pressure cleaning liquid enters the conveying tank 503, since the injection hole 504 is conical, the high-pressure liquid in the conveying groove 503 impacts the inner wall of the conical tube 501 through the injection hole 504, thereby completing the cleaning of the inner wall of the conical tube 501. At the same time, since the first valve is closed, the cleaning liquid floods the first conveying pipe 7, and the second booster pump increases the liquid pressure in the first conveying pipe 7, so that the cleaning liquid smoothly passes through the multiple filter plates 605 in the filter assembly 6. The filter plates 605 filter the cleaning liquid, and the filtered cleaning liquid returns to the tank body 1 through the first return pipe 8; when maintaining the equipment, the staff pushes the push plate 612, and the push plate 612 is During the movement, the top plate 613 on the push plate 612 pushes the lifting plate 611 along the direction of the rounded edge line, thereby moving the movable plate 609. When the movable plate 609 moves upward, the top rod 610 pushes the limiting plate 616 out of the fixed groove 606, thereby allowing the frame 604 to slide in the slide groove 602. After the staff replaces the filter plate 605, when installing the frame 604 with the filter plate 605, the frame 604 pushes the limiting plate 616 to move upward. When the frame 604 moves to a suitable position, the limiting plate 616 enters the fixed groove 606, thereby fixing the filter plate 605 in the equipment.
