Detailed Description
In order to make the objects, technical solutions and advantages of the present invention clearer, the drawings of the present invention will be combined to clearly and completely describe the technical solutions in the embodiments of the present invention.
In the first embodiment, as shown in fig. 1 to 4, the anti-clogging device for the high-pressure water nozzle comprises a first baffle assembly 1 and a second baffle assembly 2, the first baffle assembly 1 is fixedly installed on a high-pressure water pipe 3, a first water outlet hole 4 is formed in the high-pressure water pipe 3, the second baffle assembly 2 is slidably installed on the high-pressure water pipe 3, a telescopic guide assembly is fixedly installed on the first baffle assembly 1, the other end of the telescopic guide assembly is fixedly installed on the second baffle plate, a cover plate 6 is fixedly installed on the telescopic guide assembly, and a second water outlet hole 7 is formed in the cover plate 6. The diameter of the second water outlet hole 7 is larger than that of the first water outlet hole 4. When water is discharged, the cover plate 6 can not block the high-pressure water sprayed from the high-pressure water pipe 3 from cleaning the air preheater.
The working principle is as follows: the first baffle assembly 1 and the second baffle assembly 2 are arranged on the high-pressure water pipe 3, when the heating surface of the air preheater needs to be cleaned, the soot blower is started, the compression amount of the spring 505 is reduced at the moment, the second baffle assembly 2 is driven to move towards the direction far away from the first baffle assembly 1, the telescopic guide assembly moves along with the second baffle assembly 2, and the cover plate 6 is guaranteed to move on the high-pressure water pipe 3, so that the first water outlet hole 4 is opposite to the second water outlet hole 7, and high-pressure water directly washes the heating surface of the air preheater to clean the heating surface; when the heating surface of the air preheater is not required to be cleaned, the soot blower starts to withdraw from the furnace, the telescopic guide assembly moves to drive the second baffle assembly 2 to move towards the direction close to the first baffle assembly 1, the telescopic guide assembly drives the cover plate 6 to move on the high-pressure water pipe 3, the first water outlet hole 4 and the second water outlet hole 7 are staggered, and therefore smoke cannot enter the nozzle, and the nozzle blockage is avoided.
Second, this embodiment is regarded as a preferred technical scheme of first embodiment, flexible direction subassembly includes first limiting plate 501, first limiting plate 501 fixed mounting is on second baffle subassembly 2, first limiting plate 501 passes through stand pipe 503 fixedly connected with second limiting plate 502, apron 6 fixed mounting is between first limiting plate 501 and second limiting plate 502, fixed mounting has telescopic link 504 between second limiting plate 502 and the first baffle subassembly 1, the cover is equipped with spring 505 on the telescopic link 504. Spring 505 suit is on telescopic link 504, and when the soot blower need wash air heater or withdraw from, the flexible volume of spring 505 changed to remove first limiting plate 501 and second limiting plate 502, drive apron 6 and remove, thereby drive first apopore 4 and second apopore 7 stagger or coincide. The compression spring 505 can realize the linear motion of the device, the design of the spring 505 can adjust the tension and the deformation at will, and the replacement period of the spring 505 is prolonged.
The first limiting plate 501 is triangular, and the mounting height of the first limiting plate 501 is matched with the mounting height of the supporting plate 8 of the soot blower. The backup pad 8 of soot blower is the same with first limiting plate 501's height, and during the soot blower removed, drives backup pad 8 and supports and lean on first limiting plate 501 to apron 6 on the flexible guide assembly of adjustment takes place the displacement.
The above embodiments are only used to illustrate the technical solution of the present invention, and not to limit it; the pattern filling in the drawings of the utility model does not represent the material of the structure, and only distinguishes the structure; although the present invention has been described in detail with reference to the foregoing embodiments, it should be understood by those skilled in the art that: the technical solutions described in the foregoing embodiments may still be modified, or some technical features may be equivalently replaced; such modifications and substitutions do not depart from the spirit and scope of the present invention in its corresponding aspects.
