Technical Field

[0001] The utility model relates to the field of energy-saving control devices, in particular to an energy-saving control device for a coal-fired boiler. Background Art

[0002] Coal-fired boilers are generally called coal-fired steam boilers. Existing coal-fired boilers are mainly divided into vertical coal-fired steam boilers and horizontal coal-fired steam boilers. They are mainly composed of boiler bodies, burners, conveying pipelines and control devices. With the development of modern technology, energy-saving control devices are gradually replacing traditional control devices and becoming the mainstream.

[0003] However, the current energy-saving control devices still have some shortcomings. For example, the automatic dust removal effect of the existing energy-saving control devices is poor, which causes the staff to spend a long time cleaning the dust filter on the outer surface of the energy-saving control device (the existing cleaning methods are mostly manual wiping or disassembly and cleaning), which brings certain interference to the cleaning efficiency of the staff, and thus there are certain usage defects.

[0024] Embodiment 2

[0025] like Figure 1 , Figure 2 and Figure 4As shown, a positioning mounting plate 2 is embedded and installed on the side of the coal-fired boiler body 1, and an energy-saving control cabinet 3 is fixedly installed on the outer surface of the positioning mounting plate 2, and a dust-proof ventilation component 4 is symmetrically embedded and installed on the outer side of the energy-saving control cabinet 3. The dust-proof ventilation component 4 includes a carrier frame 41, a positioning block 42 and a dust-proof net 43, and the positioning blocks 42 are symmetrically installed on the side of the carrier frame 41. The external dimensions of the carrier frame 41 are completely consistent with the internal dimensions of the installation opening on the side of the energy-saving control cabinet 3, and the carrier frame 41 and the energy-saving control cabinet 3 form a snap-fit ​​structure. By setting the carrier frame 41 and the energy-saving control cabinet 3 in a snap-fit ​​structure, the carrier frame 41 is easy for the staff to quickly disassemble and assemble, and the positioning block 42 is bolted to the inner side of the energy-saving control cabinet 3. The energy-saving control cabinet 3 is connected to each other, and a dustproof net 43 is fixedly installed on the inner surface of the carrier frame 41. The side of the energy-saving control cabinet 3 is snap-fitted with a dust collecting assembly 10, and the dust collecting assembly 10 includes a dust collecting box 101 and a limiting rod 102, and the limiting rod 102 is symmetrically installed on the side of the dust collecting box 101, and the end of the limiting rod 102 is snap-fitted with the interior of the energy-saving control cabinet 3, and the other end of the limiting rod 102 is fixedly connected to the side of the dust collecting box 101, and the dust collecting box 101 forms a snap-fit ​​structure with the energy-saving control cabinet 3 through the limiting rod 102.

[0026] In actual use, when the staff needs to clean the outer surface of the dust-proof ventilation component 4, the staff turns on the drive motor 7 through the controller. When the drive motor 7 starts to run, it drives the reciprocating screw 6 to rotate inside the fixed plate 5. At this time, through the connection of the connecting mechanism 93 and the guided sliding of the guide slide bar 8, the fixed rod 92 drives the cleaning plate 91 to move up and down along the outer surface of the energy-saving control cabinet 3, so that the cleaning plate 91 drives the cleaning brush 94 to automatically clean the outer surface of the dust-proof net 43. At this time, the dust and other impurities cleaned by the cleaning component 9 automatically fall down into the interior of the dust collecting box 101, and because the interior of the dust collecting box 101 is filled with a certain height of water, the dust and other impurities can be automatically collected and processed. When the ventilation assembly 4 is deeply cleaned, the staff turns the bolt to loosen the positioning block 42 and the energy-saving control cabinet 3, then the staff grabs the carrier frame 41 and takes it out from the side of the energy-saving control cabinet 3, and then the staff deeply cleans the dust net 43. When the dust net 43 is cleaned, the staff reinstalls the dust-proof ventilation assembly 4 into the side of the energy-saving control cabinet 3, and then the staff grabs the dust collecting assembly 10 and removes it from the side of the energy-saving control cabinet 3. Then the staff pours out the dirty water in the dust box 101 and rinses it. When the interior of the dust box 101 is rinsed, the staff injects a certain amount of clean water into it, and finally completes the installation of the dust collecting assembly 10 by inserting the limit rod 102 into the interior of the energy-saving control cabinet 3.
