[0012] Specifically, the two connecting rods are positioned parallel to each other, and the scraper is arranged vertically.

[0013] A method of a centrifugal device for producing a chemical reagent comprises the following steps: Step 1: Turn the handle out of the positioning pin to release the screw positioning, and let the screw rotate clockwise or counterclockwise. The screw thread rotation force drives the connecting plate to drive the lifting rod to rise or fall along the guide column, and the corner of the workbench falls or rises. The workbench is leveled. After leveling, turn the handle to cover the positioning pin at the corresponding position to brake the screw, so that the workbench is always in a horizontal state, which plays a role in protecting the parts. Step 2: put the material into the drum, close the cover, let the block block the lock tongue under the action of the spring force, start the motor, and rotate the drum through the first gear and the second gear. The material is centrifuged in the drum, and the liquid flows out from the drum mesh, while the suspended matter is blocked in the drum. Open the discharge pipe, and the extracted liquid can be discharged from the material box, thereby realizing the filtration of chemical reagents; Step 3: During the filtering process, the first gear drives the third gear to rotate, the generator generates electricity, the capacitor stores charge, and the indicator light is always on, indicating that the equipment is operating normally. The electromagnet generates a magnetic field to attract the slide seat to prevent the box cover from opening, thereby avoiding potential safety hazards. When the motor stops running, the rotation of the first gear and the drum gradually decays due to inertia. During this process, the capacitor discharges, allowing the electromagnet and the indicator light to be closed with a delay until the drum stops rotating completely, the indicator light is always closed, and the electromagnet is completely powered off. Only then can the box cover be opened to prevent the box cover from being opened suddenly during operation, thereby avoiding potential safety hazards. Step 4. When the filter cake on the inner wall of the drum needs to be removed, the worm is rotated clockwise by the knob. Under the transmission of the worm and the worm wheel, the connecting rod swings downward, and the scraper gradually moves to the right. The fourth gear drives the rack to drive the insertion rod to move to the right until the scraper contacts the inner wall of the drum. The insertion rod moves out of the limit groove, releasing the positioning of the hollow cylinder, allowing the scraper to rotate, scraping off the filter cake on the inner wall of the drum, taking out the filter cake, and completing the cleaning of the inner wall of the drum.

[0014] The beneficial effects of the present invention are: 1. The present invention rotates the screw clockwise or counterclockwise, and the screw thread rotation force drives the lifting rod to rise or fall, thereby changing the height of the corners of the workbench, achieving leveling of the workbench, uniform force on the drum, and extending the service life.

[0015] 2. The present invention uses a generator to generate electricity to energize the capacitor, the electromagnet and the indicator light, the capacitor is charged, the indicator light is always on, the electromagnet magnetic field attracts the slide seat, the block is fixed, and the box cover is prevented from being opened when filtering materials. When the motor stops running, the capacitor is discharged to compensate the electromagnet and the indicator light for electric energy until the drum stops completely and the electromagnet and the indicator light fail. Only then can the box cover be opened. The filter has a self-locking function for filtering operations to avoid the occurrence of safety hazards. 3. The present invention rotates the worm clockwise, and under the transmission of the worm and the worm wheel, the connecting rod drives the scraper to move outward, and under the transmission of the fourth gear and the rack, the insertion rod moves outward until the scraper contacts the inner wall of the drum, and the insertion rod moves out of the limiting groove. At this time, the scraper is rotated along the inner wall of the drum to scrape off the filter cake on the inner wall of the drum, thereby achieving the purpose of cleaning the drum. The scraper can be stored, and cleaning the drum saves time and effort. BRIEF DESCRIPTION OF THE DRAWINGS

[0024] Working principle: Step 1: Turn the handle 27 out of the positioning pin 25 to release the positioning of the screw 26, and let the screw 26 rotate clockwise or counterclockwise. The thread rotation force of the screw 26 drives the connecting plate 28 to drive the lifting rod 22 to rise or fall along the guide column 21, and the corner of the workbench 1 is lowered or raised. The workbench 1 is leveled. After leveling, turn the handle 27 to cover the positioning pin 25 at the corresponding position, brake the screw 26, and keep the workbench 1 in a horizontal state at all times, so as to protect the parts. Step 2: put the material into the drum 8, close the box cover 4, let the block 78 block the lock tongue 5 under the elastic force of the spring 77, start the motor 64, and drive the drum 8 to rotate through the first gear 63 and the second gear 66. The material is centrifuged in the drum 8, and the liquid flows out from the mesh of the drum 8, while the suspended matter is blocked in the drum 8. Open the discharge pipe 10, and the extracted liquid can be discharged from the material box 3, thereby realizing the filtration of chemical reagents; Step 3, during the filtering process, the first gear 63 drives the third gear 67 to rotate, the generator 65 generates electricity, the capacitor 72 stores charge, and the indicator light 74 is always on, indicating that the equipment is operating normally, and the electromagnet 73 generates a magnetic field to attract the slide 76 to prevent the box cover 4 from opening, thereby avoiding potential safety hazards. When the motor 64 stops running, the rotation of the first gear 63 and the drum 8 gradually decays due to inertia. During this process, the capacitor 72 discharges, allowing the electromagnet 73 and the indicator light 74 to be closed with a delay until the drum 8 completely stops rotating, the indicator light 74 is always closed, and the electromagnet 73 is completely powered off. Only then can the box cover 4 be opened, thereby preventing the box cover 4 from being opened suddenly during operation, thereby avoiding potential safety hazards. Step 4. When the filter cake on the inner wall of the drum 8 needs to be removed, the worm 94 is rotated clockwise by the knob 95. Under the transmission of the worm 94 and the worm wheel 910, the connecting rod 99 swings downward, and the scraper 911 gradually moves to the right. The fourth gear 96 drives the rack 97 to drive the insertion rod 98 to move to the right until the scraper 911 contacts the inner wall of the drum 8. The insertion rod 98 moves out of the limiting groove 92, releasing the positioning of the hollow cylinder 93, allowing the scraper 911 to rotate, scrape off the filter cake on the inner wall of the drum 8, take out the filter cake, and complete the cleaning of the inner wall of the drum 8.

A centrifugal method for producing a chemical reagent, which is applied to a centrifugal device for producing a chemical reagent as claimed in claim 8, characterized in that: The following steps are involved: Step 1: rotate the handle (27) out of the positioning pin (25) to release the positioning of the screw (26), and allow the screw (26) to rotate clockwise or counterclockwise. The thread rotation force of the screw (26) drives the connecting plate (28) to drive the lifting rod (22) to rise or fall along the guide column (21), and the corner of the workbench (1) is lowered or raised. The workbench (1) is leveled. After leveling, the handle (27) is rotated to be sleeved on the positioning pin (25) at the corresponding position to brake the screw (26), so that the workbench (1) is always in a horizontal state, thereby protecting the components. Step 2: put the material into the drum (8), close the box cover (4), and allow the stopper (78) to block the lock tongue (5) under the elastic force of the spring (77), start the motor (64), and drive the drum (8) to rotate through the first gear (63) and the second gear (66), so that the material is centrifuged in the drum (8), and the liquid flows out from the mesh of the drum (8), while the suspended matter is blocked in the drum (8), and the discharge pipe (10) is opened to discharge the extracted liquid from the material box (3), thereby achieving chemical reagent filtration; Step 3, during the filtering process, the first gear (63) drives the third gear (67) to rotate, the generator (65) generates electricity, the capacitor (72) stores charge, the indicator light (74) is always on, indicating that the equipment is operating normally, the electromagnet (73) generates a magnetic field, attracts the slide seat (76), and prevents the box cover (4) from opening, thereby avoiding potential safety hazards. When the motor (64) stops running, the rotation of the first gear (63) and the drum (8) gradually decays due to inertia. During this process, the capacitor (72) discharges, allowing the electromagnet (73) and the indicator light (74) to close with a delay until the drum (8) completely stops rotating, the indicator light (74) is always closed, and the electromagnet (73) is completely powered off. Only then can the box cover (4) be opened, thereby preventing the box cover (4) from being opened suddenly during operation, thereby avoiding potential safety hazards. Step 4: When the filter cake on the inner wall of the drum (8) needs to be removed, the worm (94) is rotated clockwise by the knob (95). Under the transmission of the worm (94) and the worm wheel (910), the connecting rod (99) swings downward, the scraper (911) gradually moves to the right, and the fourth gear (96) drives the rack (97) to drive the insertion rod (98) to move to the right until the scraper (911) contacts the inner wall of the drum (8). The insertion rod (98) moves out of the limiting groove (92), releases the positioning of the hollow cylinder (93), and allows the scraper (911) to rotate, scraping off the filter cake on the inner wall of the drum (8). The filter cake is removed, and the cleaning of the inner wall of the drum (8) is completed.
