Technical Field

[0001] This utility model relates to the field of NOBS production technology, specifically to a solid-liquid centrifugal separation device for NOBS production. Background Technology

[0002] NOBS is a rubber vulcanization accelerator, commonly used in the processing of materials such as natural rubber and synthetic rubber. It has the characteristics of after-effect and rapid vulcanization, and is suitable for the production of rubber products such as tires and conveyor belts. During the production process, NOBS will generate fixed impurities, which require the use of centrifugal equipment to separate the solid and liquid.

[0003] However, existing solid-liquid centrifugal separation equipment for NOBS production is inconvenient to remove and clean its internal annular stainless steel filter screen, and even after cleaning, it is difficult to accurately reinstall it inside the equipment, affecting work efficiency. To address these issues, there is an urgent need for innovative design based on existing solid-liquid centrifugal separation equipment for NOBS production. Utility Model Content

[0004] The purpose of this invention is to provide a solid-liquid centrifugal separation device for NOBS production, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a solid-liquid centrifugal separation device for NOBS production, comprising a separation chamber, an interior rotatable support plate, a bottom plate attached to the top of the support plate, a positioning groove through which a positioning rod passes, the lower end of the positioning rod gradually decreasing in diameter, the positioning rod being fixedly connected to the bottom plate, a movable ring with a ring-shaped stainless steel filter screen at the top of the bottom plate, a rotatable sleeve at the top of the separation chamber, the inner side of the movable sleeve fitting against the outer side of the movable ring, a limiting groove in the movable sleeve engaging a limiting block, the limiting block being fixedly connected to the movable ring, and fixing rods fixed on both sides of the top of the movable ring.

[0006] Preferably, a slot is provided on one side of the limiting block, and a first screw is threaded on the side wall of the movable sleeve, with one end of the first screw engaging with the slot.

[0007] Preferably, an L-shaped plate is fixed to the top of the movable sleeve, and a second screw is threaded through the top of the L-shaped plate, with the second screw abutting against the first screw.

[0008] Preferably, the top of the movable ring is threaded with a top cap.

[0009] Preferably, the top of the base plate is fixedly connected to the bottom of the movable ring via support columns, and the support columns are distributed at equal angles about the central axis of the base plate.

[0010] Preferably, the bottom of the separation box has a rotating shaft, which is fixedly connected to the support plate and the motor.

[0011] Preferably, a drain pipe is provided on one side of the bottom of the separation box, and a manual valve is installed on the drain pipe. The inner bottom of the separation box is designed to be inclined, and the lowest point of the inner bottom of the separation box is located near the end of the drain pipe.

[0012] Compared with the prior art, the beneficial effects of this utility model are: the solid-liquid centrifugal separation equipment for NOBS production can separate the end of the first screw from the slot by rotating the first screw, so that the annular stainless steel filter screen can be removed from the fixed position. The annular stainless steel filter screen can be lifted out of the separation box by the fixing rod, so as to facilitate the removal and cleaning of the annular stainless steel filter screen from the separation box. Rotating the movable ring with the fixed rod causes the limiting block on the movable ring to insert into the limiting groove, thus positioning the top of the annular stainless steel filter screen. Then, the fixed rod pushes the movable ring to rotate, which in turn drives the positioning rod to rotate through the annular stainless steel filter screen and the base plate. Since the diameter of the lower end of the positioning rod gradually decreases, it is convenient for the lower end of the positioning rod to insert into the positioning groove, thus positioning the bottom of the annular stainless steel filter screen. This facilitates the accurate installation of the annular stainless steel filter screen back into the separation box, improving the efficiency of disassembling and reinstalling the annular stainless steel filter screen. The second screw can be easily raised and lowered by the screw plate. When the bottom outer side of the second screw abuts against the other end of the first screw, the first screw can be locked to prevent it from loosening, thus improving the stability of the limit block and the movable sleeve.

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0016] Please see Figure 1-4 This utility model provides a technical solution: a solid-liquid centrifugal separation device for NOBS production, including a separation box 1. A rotatable support plate 2 is installed inside the separation box 1. A bottom plate 3 is attached to the top of the support plate 2. A positioning groove 4 is formed on the side of the support plate 2. A positioning rod 5 slides through the positioning groove 4. The lower diameter of the positioning rod 5 gradually decreases, making it smaller than the diameter of the positioning groove 4. Since the lower end of the positioning rod 5 is inserted into the positioning groove 4, both the positioning groove 4 and the positioning rod 5 are angularly distributed about the central axis of the bottom plate 3. The upper end of the positioning rod 5 is fixedly connected to the bottom of the bottom plate 3, improving the stability of the connection between the support plate 2 and the bottom plate 3. The lower end of an annular stainless steel filter screen 6 is fixed to the top of the bottom plate 3 by bolts. The lower end of a movable ring 7 is fixed to the upper end of the annular stainless steel filter screen 6 by bolts. The top of the separation box 1 is sealed. The bearing is rotatably mounted with a movable sleeve 8. The inner side of the movable sleeve 8 fits against the outer side of the movable ring 7. A sealing ring is provided on the outer side of the movable ring 7 and the inner side of the movable sleeve 8. The outer side of the sealing ring is fixedly connected to the inner side of the movable sleeve 8. A limit groove 9 is opened on the inner side of the movable sleeve 8. A limit block 10 is engaged inside the limit groove 9. A sealing gasket is provided between the limit groove 9 and the limit block 10. The sealing gasket is fixedly connected to the limit groove 9. The limit groove 9 and the limit block 10 are symmetrically distributed about the central axis of the movable ring 7. The outer side of the limit block 10 is fixedly connected to the outer side of the movable ring 7, ensuring that when the movable ring 7 rotates, the movable ring 7 can drive the movable sleeve 8 to rotate through the engagement of the limit groove 9 and the limit block 10. Fixing rods 21 are fixed on both sides of the top of the movable ring 7. The fixing rods 21 facilitate the removal of the movable ring 7, the annular stainless steel filter screen 6, and the bottom plate 3 from the inside of the separation box 1.

[0017] A slot 11 is provided on one side of the limiting block 10, and a first screw 12 is threaded through the side wall of the movable sleeve 8. One end of the first screw 12 is engaged with the slot 11, and both sides of the other end of the first screw 12 are fixed with screw plates. The screw plates facilitate the disassembly and installation of the first screw 12. The first screw 12 can be used to fix the limiting block 10 and the movable sleeve 8.

[0018] An L-shaped plate 13 is fixed to the top of the movable sleeve 8. A second screw 14 is threaded through the top of the L-shaped plate 13. The bottom outer side of the second screw 14 abuts against the other end of the first screw 12. The bottom outer side of the second screw 14 has a smooth surface. Tightening plates are fixed to both sides of the top of the second screw 14. The tightening plates facilitate the raising and lowering of the second screw 14. When the bottom outer side of the second screw 14 abuts against the other end of the first screw 12, the first screw 12 can be locked to prevent the first screw 12 from loosening, thus improving the stability of the fixation between the limit block 10 and the movable sleeve 8.

[0019] The top of the movable ring 7 is threaded with a top cover 15. A sealing ring is provided at the connection between the movable ring 7 and the top cover 15. A screw plate is fixed to the top of the top cover 15, which facilitates the disassembly and installation of the top cover 15.

[0020] A support column 16 is fixed to the top side of the base plate 3 by bolts. The upper end of the support column 16 is fixed to the bottom side of the movable ring 7 by bolts. The support columns 16 are distributed at equal angles about the central axis of the base plate 3, which improves the connection strength between the base plate 3 and the movable ring 7 and protects the annular stainless steel filter screen 6.

[0021] A rotating shaft 17 is rotatably mounted on the bottom of the separation box 1 through a sealed bearing. The upper end of the rotating shaft 17 is fixedly connected to the center of the bottom of the support plate 2, and the lower end of the rotating shaft 17 is fixedly connected to the top output end of the motor 18. The outer wall of the motor 18 is fixed to the bottom of the separation box 1 with bolts. By starting the motor 18, the rotating shaft 17 and the support plate 2 can be rotated.

[0022] A drain pipe 19 is provided on one side of the bottom of the separation tank 1. A manual valve 20 is installed on the drain pipe 19. The bottom of the separation tank 1 is designed to be inclined. The lowest point of the bottom of the separation tank 1 is located near the end of the drain pipe 19. The filtered NOBS can be discharged through the drain pipe 19.

[0023] Working principle: When using the solid-liquid centrifugal separation equipment for NOBS production, first rotate the top cover 15 to remove it from the top of the movable ring 7, then pour the NOBS to be filtered into the interior of the movable ring 7, and finally reinstall the top cover 15 back into its original position. Next, start motor 18. Motor 18 drives the rotating shaft 17, support plate 2, positioning groove 4, positioning rod 5, base plate 3, annular stainless steel filter screen 6, support column 16, movable ring 7, top cover 15, movable sleeve 8, limiting groove 9 and limiting block 10 to rotate simultaneously. Under the action of centrifugal force, the NOBS liquid inside the annular stainless steel filter screen 6 enters the bottom of the separation box 1 through the filter holes on it, while the solid impurities in NOBS remain inside the annular stainless steel filter screen 6. When there are many solid impurities inside the annular stainless steel filter screen 6 that need to be removed for cleaning, rotate the second screw 14. Since the second screw 14 is threadedly connected to the L-shaped plate 13, the second screw 14 moves upward and separates from the first screw 12. Then rotate the first screw 12. Since the first screw 12 is threadedly connected to the movable sleeve 8, the end of the first screw 12 separates from the slot 11, causing the movable ring 7 to disengage from the fixed position. Then, through the fixing rod 21, the positioning rod 5, the base plate 3, the annular stainless steel filter screen 6 and the movable ring 7 are lifted out of the separation box 1, thus making it convenient for the annular stainless steel filter screen 6 to be removed from the separation box 1 for cleaning. After the annular stainless steel filter screen 6 is cleaned, the positioning rod 5, the base plate 3, the annular stainless steel filter screen 6, and the movable ring 7 are inserted into the separation box 1, and the limiting block 10 on the movable ring 7 is inserted into the limiting groove 9. Then, the movable ring 7 is pushed to rotate by the fixing rod 21. The movable ring 7 drives the positioning rod 5 to rotate through the annular stainless steel filter screen 6 and the base plate 3. Since the diameter of the lower end of the positioning rod 5 gradually decreases, it is convenient for the lower end of the positioning rod 5 to be inserted into the positioning groove 4 until the lower end of the positioning rod 5 passes through the interior of the positioning groove 4, thus completing the bottom positioning of the annular stainless steel filter screen 6. Then, the first screw 12 is rotated so that the end of the first screw 12 engages with the slot 11, thus fixing the annular stainless steel filter screen 6 and the movable ring 7. The second screw 14 is rotated so that the outer bottom of the second screw 14 abuts against the other end of the first screw 12, thus locking the first screw 12 and preventing it from loosening.

[0024] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
