On the other hand, dirt may also mix into the product, reducing the purity of the product and affecting its performance and market competitiveness. The existing descaling method for polyolefin wax preparation equipment is mainly manual periodic disassembly and cleaning.

[0022] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0023] This utility model discloses a descaling mechanism for a polyolefin wax preparation apparatus.

[0024] This utility model provides, for example Figure 1-3The descaling mechanism of the polyolefin wax preparation apparatus shown includes a reaction vessel 1. A circular hole is opened on the upper surface of the reaction vessel 1. A sleeve 2 is rotatably connected inside the circular hole. A fixing block 3 is fixedly connected to the lower end of the sleeve 2. Both ends of the fixing block 3 are provided with sliding grooves. Sleeves 4 are slidably arranged inside the two sliding grooves. One end of each sleeve 4 is fixedly connected to an L-shaped scraper 5. Both L-shaped scrapers 5 are matched with the inner wall of the reaction vessel 1. A cavity is provided inside the fixing block 3. An adjustment mechanism is provided inside the cavity. Both sleeves 4 can move through the adjustment mechanism. A fixing frame 6 is fixedly connected to the upper surface of the reaction vessel 1. A driving mechanism is provided inside the fixing frame 6. The sleeve 2 is rotated through the driving mechanism. A limit mechanism is provided on the upper surface of the fixing frame 6. The limit mechanism matches the adjustment mechanism.

[0025] Before cleaning the dirt on the inner wall of the reactor 1, move the two sleeves 4 so that the two L-shaped scrapers 5 fit against the inner wall of the reactor 1. Then rotate the sleeve 2 to make the two L-shaped scrapers 5 rotate to clean the dirt on the inner wall of the reactor 1.

[0026] To move the L-shaped scraper 5, such as Figure 1-3 As shown, the adjusting mechanism includes a rotating rod 7, a first bevel gear 8, two second bevel gears 9, and two lead screws 10. The two lead screws 10 are rotatably connected to the interior of corresponding grooves. Two sleeves 4 are threaded onto the walls of the corresponding lead screws 10. The rotating rod 7 is rotatably connected to the interior of the cavity. The upper end of the rotating rod 7 penetrates the upper surface of the cavity and extends into the interior of the sleeve 2. The first bevel gear 8 is fixedly sleeved onto the lower wall of the rotating rod 7. The two second bevel gears 9 are fixedly sleeved onto the walls of the corresponding lead screws 10 and both mesh with the first bevel gear 8. The limiting mechanism includes a U-shaped plate 14. The assembly includes a rod 15, a stop block 16, a spring 17, a pull ring 18, and a rotating plate 19. The rotating plate 19 is fixedly connected to the upper end of the rotating rod 7. A U-shaped plate 14 is fixedly connected to the upper surface of the rotating plate 19. A through hole is provided on the upper surface of the U-shaped plate 14. The rod 15 is slidably disposed inside the through hole. The stop block 16 is fixedly sleeved on the rod wall of the rod 15. The spring 17 is slidably sleeved on the rod wall of the rod 15. The pull ring 18 is fixedly connected to the upper end of the rod wall of the rod 15. Multiple insertion holes are provided around the upper surface of the fixing frame 6. The lower end of the rod 15 passes through the upper surface of the rotating plate 19 and matches each insertion hole.

[0027] Pulling the pull ring 18 upwards causes the insertion rod 15 to move upwards, compressing the spring 17 and disengaging the lower end of the insertion rod 15 from the insertion hole on the upper surface of the fixed frame 6. At this point, rotating the rotating plate 19 causes the rotating rod 7 to rotate. The first bevel gear 8 at the lower end of the rotating rod 7 rotates accordingly, and the two second bevel gears 9 meshing with the first bevel gear 8 respectively drive the corresponding lead screw 10 to rotate. Since the sleeve 4 is threaded onto the lead screw 10, when the lead screw 10 rotates, the sleeve 4 moves along the lead screw 10 within the groove of the fixed block 3, thereby moving the L-shaped scraper 5. After adjusting to the appropriate position, releasing the pull ring 18 allows the lower end of the insertion rod 15 to insert into the corresponding insertion hole under the elastic force of the spring 17, fixing the position of the rotating rod 7 and completing the initial adjustment of the L-shaped scraper 5 position.

[0028] To make sleeve 2 rotate, such as Figure 1 As shown, the drive mechanism includes a motor 11, a drive gear 12, and a driven gear 13. The motor 11 is fixedly connected to the upper surface of the fixed frame 6, and the output end of the motor 11 passes through the upper surface of the fixed frame 6. The drive gear 12 is fixedly sleeved on the output end of the motor 11, and the driven gear 13 is fixedly sleeved on the outer surface of the sleeve 2 and meshes with the drive gear 12.

[0029] When motor 11 is powered on, its output drives the driving gear 12 to rotate. The driving gear 12 meshes with the driven gear 13, which is fixedly fitted onto the outer surface of the sleeve 2. This causes the sleeve 2 to rotate within the circular hole on the upper surface of the reactor 1. A fixing block 3 is fixedly connected to the lower end of the sleeve 2. The fixing block 3 rotates accordingly, causing the L-shaped scraper 5 to rotate around the central axis of the reactor 1. The rotating L-shaped scraper 5 contacts the inner wall of the reactor 1, scraping off the dirt from the inner wall.

[0030] To prevent the two sleeves 4 from rotating, such as Figure 1-2 As shown, the two slides are symmetrically provided with limiting grooves inside, and each limiting groove is slidably provided with a limiting block 20 inside. Each limiting block 20 is fixedly connected to the outer surface of the corresponding sleeve 4.

[0031] Each limiting block 20 can be used to limit the movement of the two sleeves 4.

[0032] To speed up the reaction process, such as Figure 1 As shown, multiple stirring rods 21 are fixedly connected to one side of each of the two L-shaped scrapers 5.

[0033] When the reactor 1 is working normally, move the L-shaped scraper 5 to separate it from the inner wall of the reactor to prevent excessive scraping. At this time, the stirring rod 21 can accelerate the reaction process. At the same time, the stirring rod 21 can stir the residual dirt and liquid in the reactor 1 to further disperse the dirt and facilitate subsequent cleaning.

[0034] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
