Description

Technical Field

[0001] This utility model relates to the field of sealing ring replacement technology, and in particular to an auxiliary device for replacing sealing rings in a hydraulcrete machine for a paperboard machine. Background Technology

[0002] In the paperboard production process, the hydraulic pulper is the core equipment that breaks down waste paper raw materials into pulp. The sealing ring at its feed inlet plays a crucial role in preventing pulp leakage and maintaining internal pressure.

[0003] Because hydraulic pulpers operate in high-humidity, high-wear, and highly corrosive environments, their sealing rings are prone to failure due to pulp erosion, mechanical wear, or thermal expansion and contraction. This can lead to pulp leakage, increased equipment energy consumption, and even shutdowns. Sealing rings are typically attached to the feed inlet using bolts or glue. However, manually removing old sealing rings requires scraping away pulp residue and old sealant from the feed inlet surface to ensure a smooth contact surface. When attaching new rings with bolts or glue, repeated calibration is necessary to ensure accurate installation. This results in lengthy replacement times, severely impacting continuous production line operation. Therefore, we propose an auxiliary device for replacing sealing rings in hydraulic pulpers for paperboard machines. Utility Model Content

This device can solve the problem that sealing rings are usually attached to the feed inlet with bolts or glue. When manually removing the old sealing ring, it is necessary to use a scraper to clean the pulp residue and old sealant on the surface of the feed inlet to ensure that the contact surface is flat. When using bolts or glue to attach the new ring, it is necessary to repeatedly calibrate the position to ensure the accuracy of the sealing ring installation position. As a result, each replacement takes a long time and seriously affects the continuous operation of the production line.

[0026] Please see Figure 1-4 This utility model provides a technical solution: an auxiliary device for replacing the sealing ring of a hydraulcrete machine in a paperboard machine, comprising:

[0027] The horizontal pulper body 1 and the feed square pipe 4 are fixedly connected to the outer surface of the horizontal pulper body 1 and are connected to the interior of the horizontal pulper body 1.

[0028] The sealing replacement structure is located on the feed square tube 4;

[0029] The sealing replacement structure includes a square sealing ring 5 and four positioning rods 6. The top of the feed square tube 4 has four slots 8. The four positioning rods 6 are fixedly connected to the bottom of the square sealing ring 5. The square sealing ring 5 is in contact with the top of the feed square tube 4. The square sealing ring 5 is made of rubber. The four positioning rods 6 are inserted into the corresponding slots 8. A slot 7 is opened on one side of each of the four positioning rods 6. A through groove 15 is opened inside each of the four slots 8. Two limiting slide grooves 11 are opened on both sides of the feed square tube 4. The four limiting slide grooves 11 are connected to the corresponding through grooves 15. The inside of each of the four limiting slide grooves 11 is slidably connected to a limiting slide plate 13. A locking block 14 is fixedly connected to one side of each of the four limiting slide plates 13. The four locking blocks 14 are slidably connected to the inside of the corresponding through grooves 15. The four locking blocks 14 are engaged with the corresponding slots 7.

[0030] The sealing replacement structure also includes four springs 12, four sealing limit plates 9, and four connecting belts 10. One end of each of the four springs 12 is fixedly connected to the side of the corresponding limit slide plate 13 away from the locking block 14. The ends of each of the four springs 12 away from the corresponding limit slide plate 13 are fixedly connected to the inside of the corresponding limit slide groove 11. The four sealing limit plates 9 are all interference-fitted with the inside of the corresponding limit slide groove 11. One end of each of the four connecting belts 10 is fixedly connected to the corresponding sealing limit plate 9. The ends of each of the four connecting belts 10 away from the corresponding sealing limit plate 9 are fixedly connected to the feed square tube 4. All four sealing limit plates 9 are made of rubber.

[0031] A transmission component 2 is fixedly installed at one end of the horizontal pulper body 1, and a discharge pipe 3 is fixedly connected to the side of the horizontal pulper body 1 near the transmission component 2. The discharge pipe 3 is connected to the interior of the horizontal pulper body 1.

[0032] Furthermore, when using this device, if it is necessary to disassemble the sealing ring, the user first pulls the connecting belt 10 to pull the sealing limiting plate 9 out of the limiting slide groove 11, releasing the restraint on the limiting slide plate 13. The spring 12 is in a supported state. Then, the user pulls the limiting slide plate 13 to move horizontally under the guidance inside the limiting slide groove 11. The movement of the limiting slide plate 13 will compress the spring 12 and pull the locking block 14 to move, thereby causing the locking block 14 to disengage from the slot 7 of the positioning rod 6 and release the lock on the positioning rod 6.

[0033] Simultaneously, the four limiting slide plates 13 are pulled, and then the square sealing ring 5 is lifted upwards, so that the positioning rod 6 is disengaged from the slot 8, completing the disassembly of the old sealing ring.

[0034] Align the positioning rod 6 of the new square sealing ring 5 with the slot 8 at the top of the feed square tube 4 and insert it vertically until the positioning rod 6 is fully inserted into the slot 8. At this time, the locking block 14 is squeezed and retracted into the through groove 15 when the positioning rod 6 is inserted into the slot 8. When the slot 7 is aligned with the through groove 15, the locking block 14 will be reset under the action of the corresponding spring 12 and engage with the slot 7, which facilitates locking and limiting the positioning rod 6, thereby completing the fixing of the sealing ring. The rubber square sealing ring 5 fits tightly with the top of the feed square tube 4 to form a seal. Finally, the sealing limiting plate 9 is inserted into the limiting slide groove 11 to limit the limiting slide plate 13.

[0035] The elastic snap-fit ​​structure of spring 12 and locking block 14 allows for the disassembly and installation of the sealing ring without the need for tools such as scrapers and wrenches. At the same time, the precise fit between positioning rod 6 and slot 8 avoids complex cleaning and calibration steps, greatly simplifies the disassembly process, significantly shortens the time for a single replacement, ensures the accuracy of the sealing ring installation position, and further improves production efficiency.
