Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field that dust collector's dust collecting cylinder dredges, especially a dust collector dust collecting cylinder's automatic dredging mechanism. BACKGROUND

[0002] The garbage incinerator is used for incinerating domestic waste to realize the treatment of domestic waste, and a large amount of flue gas with dust is generated in the incineration process. In order to filter out the dust in the flue gas, a dust collector is usually connected to the flue duct of the garbage incinerator to filter out the dust in the flue gas.

[0003] Among them, the structure of a dust collector is as shown in Figure 1 The dust collector comprises a shell 1, a smoke outlet pipe 2 fixedly arranged on the top of the shell 1, a filter screen 3 fixedly arranged in the inner cavity of the shell 1, a smoke inlet pipe 4 fixedly arranged on the right side wall of the shell 1, the smoke inlet pipe 4 being located below the filter screen 3, and the other end of the smoke inlet pipe 4 being connected to the flue duct of the garbage incinerator; a support 5 is fixedly arranged on the bottom surface of the shell 1 and supports the ground; a dust collecting cylinder 6 is connected to the bottom port of the shell 1, and an end cover 7 is detachably connected to the bottom surface of the dust collecting cylinder 6.

[0004] When working, the flue gas generated in the process of incinerating domestic waste by the garbage incinerator sequentially passes through the flue duct of the garbage incinerator, the smoke inlet pipe 4, the inner cavity of the shell 1, and the mesh holes of the filter screen 3, and is finally discharged from the top port of the smoke outlet pipe 2 to the next processing procedure, wherein the filter screen 3 can filter out the dust in the flue gas, and the filtered dust gradually accumulates in the dust collecting cylinder 6 to form a dust layer 8, as shown in Figure 2 .

[0030] The present invention will be further described below with reference to the accompanying drawings. The scope of protection of the present invention is not limited to the following description:

[0031] like Figures 3-6 As shown, an automatic unblocking mechanism for a dust collector's dust collection cylinder includes a hydraulic cylinder 9 fixed to the left side wall of a dust collector support 5. The piston rod of the hydraulic cylinder 9 extends to the right through the support 5, and a connecting plate 10 is fixed to its extended end. A vertically arranged cylinder 11 is welded to the connecting plate 10. The cylinder 11 is located below the end cover 7 of the dust collector. Guide rails 12 are fixed to the left and right inner side walls of the cylinder 11 along its axial direction. The two guide rails 12 are symmetrically arranged about a lead screw 14. A drive motor 13 is fixed to the bottom surface of the cylinder 11. The output shaft of the drive motor 13 extends into the cylinder 11, and a lead screw 14 is connected to its extended end. A nut 15 is threaded onto the lead screw 14. Slider blocks are fixed to the left and right side walls of the nut 15. The two sliders are slidably mounted on the two guide rails 12 respectively. The top of the cylinder 11 is closed, and the bottom of the cylinder 11 has an opening with a bottom cover fixed at the opening.

[0032] Multiple rods 16 extending upward through the top wall of the vertical cylinder 11 are fixed on the top surface of the nut 15. A scraper 17 located below the end cover 7 is fixed between the extended ends of the multiple rods 16. The diameter of the scraper 17 is equal to the inner diameter of the dust collection cylinder 6. Multiple columns 18 are fixed on the top surface of the scraper 17. The columns 18 are evenly distributed on the scraper 17. A pointed cone 19 is fixed at the top of each column 18. Multiple powder dropping holes 20 are also opened inside the scraper 17.

[0033] The drive motor 13 is fixed to the bottom surface of the bottom cover, and the output axis of the drive motor 13 passes through the bottom cover and extends into the vertical cylinder 11. Two rods 16 are fixed to the top surface of the nut 15, and the two rods 16 are symmetrically arranged about the left and right sides of the lead screw 14.

[0034] After a period of use, a dust layer 8 forms inside the dust collection cylinder 6 of this dust collector, such as... Figure 7 As shown, the specific steps for the worker to unclog dust collection cylinder 6 are as follows:

[0035] S1. The worker removes the end cap 7 from the dust collection cylinder 6, as follows: Figure 8 As shown, at this time, the dust layer 8 inside the dust collection cylinder 6 is exposed to the outside;

[0036] S2. The worker controls the piston rod of hydraulic cylinder 9 to extend to the right. The piston rod drives the connecting plate 10 to move to the right, the connecting plate 10 drives the vertical cylinder 11 to move to the right, and the vertical cylinder 11 drives the drive motor 13, lead screw 14, scraper 17 and column 18 to move to the right synchronously. When the piston rod of hydraulic cylinder 9 is fully extended, the scraper 17 is just below the dust collection cylinder 6. Figure 9 As shown;

[0037] S3. The worker controls the start of the drive motor 13, which drives the lead screw 14 to rotate. The nut 15 moves upward along the lead screw 14. Simultaneously, the slider on the nut 15 moves upward along the guide rail 12. The nut 15 drives the rod 16 to move upward, which in turn drives the scraper 17 to move upward. The scraper 17 drives the column 18 and the pointed cone 19 to move upward synchronously. The pointed cone 19 is the first to insert into the dust layer 8 inside the dust collection cylinder 6. Figure 10 As shown, the scraper 17 then enters the dust collection cylinder 6; as the scraper 17 continues to move upward, it gradually scrapes off the dust layer 8, as... Figure 11 As shown, the dust scraped off falls to the ground through the dust discharge hole 20; after the drive motor 13 has been working for a period of time, the dust layer inside the dust collection cylinder 6 can be cleaned, thus finally achieving the unblocking of the dust collection cylinder 6.

[0038] Wherein, from step S3, the dredging mechanism can make the pointed cone 19 first insert into the dust layer 8 by the linkage of the hydraulic cylinder 9 and the driving motor 13, and then gradually scrape the dust layer 8 by the scraper 17, so as to realize the automatic and rapid cleaning of the dust layer in the dust collecting cylinder 6. Therefore, compared with the manual dredging of the dust collecting cylinder 6 by the worker, the dredging mechanism can greatly reduce the working strength of the worker, and realize the dredging of the dust collecting cylinder 6 in a short time, thereby greatly improving the dredging efficiency of the dust collecting cylinder 6.

[0039] S4, when the dust collecting cylinder 6 is dredged, the worker controls the driving motor 13 to reverse, the driving motor 13 drives the screw rod 14 to rotate reversely, the nut 15 moves downward along the screw rod 14, the rod 16 moves downward driven by the nut 15, the scraper 17 moves downward driven by the rod 16, the upright column 18 and the pointed cone 19 move downward synchronously driven by the scraper 17, when the upright column 18 and the pointed cone 19 are out of the dust collecting cylinder 6, the worker controls the driving motor 13 to be closed;

[0040] S5, the worker controls the piston rod of the hydraulic cylinder 9 to retract, the connecting plate 10 moves left driven by the piston rod, the connecting plate 10 drives the upright column 11 to reset, so as to prepare for the next dredging of the dust collecting cylinder 6.

[0041] Finally, it should be noted that: the above only for the preferred embodiments of the utility model, and does not limit the utility model, although the utility model has been described in detail with reference to the foregoing embodiments, for the person skilled in the art, it still can modify the technical scheme recorded in the foregoing each embodiment, or make equivalent replacement to part of technical features.
