Description

Technical Field

[0001] This utility model relates to a cleaning device, specifically a cleaning device for a polymerization reactor used in the production of polyvinyl chloride resin, and belongs to the technical field of cleaning equipment. Background Technology

[0002] The polymerization reactor used in the production of polyvinyl chloride (PVC) resin is a key piece of equipment in the synthesis of PVC resin. By providing a high-temperature, high-pressure, and stirred reaction environment, it promotes the polymerization reaction of vinyl chloride monomer under the action of an initiator to form PVC resin. During the polymerization process, unreacted monomers, residual initiators, dispersants, and other impurities will adhere to the inner wall and internal components of the polymerization reactor. These impurities will not only affect the quality of subsequent products, but may also lead to a decrease in the heat transfer efficiency of the reactor, blockage of pipes, and even safety hazards. Therefore, it is necessary to clean the polymerization reactor regularly using cleaning equipment.

[0003] However, when the cleaning head and hose in the cleaning equipment descend, the guide tube installed on the inlet flange of the polymerization reactor can constrain the direction of the hose, making it descend vertically along the predetermined path. However, when the guide tube is installed on the flange at the inlet of the polymerization reactor, the hole on the guide tube is aligned with the threaded hole on the flange, and then it is fixed by multiple bolts that are threaded into the threaded hole on the flange. The installation by multiple bolts results in low fixing efficiency. Utility Model Content

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. 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.

[0025] Please see Figure 1-7 As shown, a cleaning device for a polymerization reactor used in polyvinyl chloride resin production includes a mounting frame 1, an adjusting frame 2 slidably connected to the mounting frame 1, a winding frame 3 mounted on the adjusting frame 2, a flexible hose 4 mounted on the winding frame 3, a cleaning head 5 mounted on the flexible hose 4, a guide tube 8 slidably connected to the flexible hose 4, and a fixing component 6 provided on the guide tube 8.

[0026] As a technical optimization of this utility model, a pressing rod 606 is fixedly connected to the connecting plate 603, and a guide rod 604 is fixedly connected inside the positioning post 601. The connecting plate 603 and the guide rod 604 are slidably connected. The setting of the guide rod 604 makes the fixed block 602 slide more smoothly.

[0027] As a technical optimization of this utility model, a second lead screw 11 is rotatably connected to the mounting frame 1, and the adjusting frame 2 is threadedly connected to the second lead screw 11. When the second driving component 12 (preferably a motor) is activated, the output shaft of the motor rotates, driving the second lead screw 11 to rotate. When the second lead screw 11 rotates, it thread-driven the adjusting frame 2 to slide downward on the mounting frame 1. When the height of the adjusting frame 2 is reduced, it is easier to inspect and maintain components such as the winding frame 3, reducing the operating height and difficulty of inspection and maintenance. The second driving component 12 is installed on the mounting frame 1, and the second lead screw 11 is driven by the second driving component 12. A guide shaft 13 is fixedly connected to the mounting frame 1, and the adjusting frame 2 is slidably connected to the guide shaft 13. The setting of the guide shaft 13 makes the sliding of the adjusting frame 2 more stable.

[0028] As a technical optimization of this utility model, the adjustment frame 2 is rotatably connected to the mounting shaft 9, and the mounting shaft 9 is fixedly connected to the guide roller 10. The guide roller 10 can guide the unwinding of the hose 4.

[0029] As a technical optimization of this utility model, the adjusting frame 2 is provided with a water absorption component 7. The water absorption component 7 includes a mounting frame 701, which is fixedly connected to the adjusting frame 2. Two sliding plates 704 are slidably connected in the mounting frame 701. A mounting block 706 is fixedly connected to the sliding plate 704. A mounting plate 707 is detachably connected to the mounting block 706. A water-absorbing cotton 708 is fixedly connected to the mounting plate 707. The water-absorbing cotton 708 can absorb moisture from the outer wall of the hose 4, preventing moisture from accelerating the aging and corrosion of the outer wall of the hose 4 and extending the service life of the hose 4. A positioning block is fixedly connected to the mounting plate 707. 709, the positioning block 709 is inserted into the mounting block 706, the mounting block 706 is threadedly connected to a knob 710, the knob 710 is inserted into the positioning block 709, the adjusting frame 2 is fixedly connected to a guide post 705, the sliding plate 704 is slidably connected to the guide post 705, the bottom of the knob 710 is fixedly connected to a rotating block 711, the mounting frame 701 is rotatably connected to a first lead screw 702, the sliding plate 704 is threadedly connected to the first lead screw 702, the two ends of the first lead screw 702 have opposite thread directions, the mounting frame 701 is mounted with a first driving member 703, the first lead screw 702 is driven by the first driving member 703.

[0030] When using this invention, if cleaning of the polymerization reactor is required, first move the mounting frame 1 to the designated position, then unwind the hose 4 using the unwinding assembly on the winding frame 3. During unwinding, the guide tube 8 descends to the inlet of the polymerization reactor under gravity. The operator can then insert the positioning post 601 on the guide tube 8 into the pre-drilled threaded hole at the inlet. During insertion, because the fixing block 602 has a trapezoidal structure, it retracts into the positioning post 601. The fixing block 602 drives the connecting plate 603 to slide, and the connecting plate 603 slides against the guide rod 604. The guide rod 604 makes the sliding of the fixing block 602 more stable. Simultaneously, the connecting plate 603 drives the pressing rod 606 to move. When it moves to the designated position, the fixing block 602 slides out under the action of the spring 605 and hooks onto the flange on the reactor. At this point, the guide tube 8 is fixed. The fixing block 602 slides out under the action of the spring 605 and hooks onto the flange at the cleaning port on the polymerization reactor, which facilitates quick fixing of the guide tube 8 and improves the fixing efficiency of the guide tube 8. The hose 4 continues to be released into the polymerization reactor. Then, the water is pressurized by the high-pressure pump and delivered to the cleaning head 5 with a special nozzle through the hose 4. The high-pressure water forms a high-speed jet through the nozzle, using its powerful impact force to break and peel off the inner surface of the polymerization reactor. The dirt on the surface is then washed away by the water flow, completing the cleaning process. When winding up the hose 4, the first drive unit 703 (preferably a motor) can be activated. When the output shaft of the motor rotates, it drives the first lead screw 702 to rotate. When the first lead screw 702 rotates, it drives the two sliding plates 704 to slide towards each other. The sliding plates 704 will slide against the guide post 705. The guide post 705 makes the sliding plates 704 slide more smoothly. At the same time, the sliding plates 704 drive the mounting block 706, mounting plate 707 and absorbent cotton 708 to move towards each other, so that the absorbent cotton 708 contacts the outer wall of the hose 4. During winding, the absorbent cotton 708 can... The moisture on the outer wall of the hose 4 is absorbed to prevent the moisture from accelerating the aging and corrosion of the outer wall of the hose 4 and to extend the service life of the hose 4. When the components such as the winding frame 3 are inspected, the second drive component 12 (preferably a motor) can be started. When the output shaft of the motor rotates, it drives the second lead screw 11 to rotate. When the second lead screw 11 rotates, the thread drives the adjusting frame 2 to slide downward on the mounting frame 1. When the adjusting frame 2 slides, it will slide with the guide shaft 13. The setting of the guide shaft 13 makes the sliding of the adjusting frame 2 more stable. When the height of the adjusting frame 2 is reduced, it is easier to inspect and maintain the components such as the winding frame 3, reducing the operating height and difficulty of the inspection.
