Description

Technical Field

[0002] The enhanced low-frequency diaphragm sonic soot blower is an advanced industrial cleaning equipment, mainly used to remove dust accumulated on the surface of equipment such as boilers and electrostatic precipitators. The working principle of the sonic soot blower is to convert compressed air into high-power sound waves and send them into the furnace. When the soot accumulated on the heating surface of the boiler is repeatedly pulled and compressed by the density waves that alternate at a certain frequency, the soot will loosen due to fatigue and fall off and be carried away by the flue gas flow, or under the action of gravity, the soot will settle into the ash hopper for discharge.

[0003] However, the existing enhanced low-frequency diaphragm sonic soot blowers have certain defects in actual use. Most of them are installed on the side wall of the boiler by screws or welding, and their height is generally relatively high. When inspecting or replacing them, workers are required to work at height, which not only has certain risks but also is inconvenient to operate. Utility Model Content

Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0025] See also Figure 1-Figure 5According to an embodiment of the present invention, an enhanced low-frequency diaphragm type sonic soot blower includes a sonic soot blower body 2, which is an enhanced low-frequency diaphragm type sonic soot blower mainly composed of a shell, a diaphragm, a compressed air device, an air path control device, an air filter, a pressure reducing valve, etc., and is mainly used to remove dust accumulated on the surface of equipment such as boilers and electrostatic precipitators. Its working principle is to use compressed air as a power source, generate low-frequency vibrations in the resonance cavity through a high-strength titanium metal diaphragm, and convert the potential energy of the compressed air into low-frequency sound energy, which is then amplified by a loudspeaker 5 to form high-energy sound waves, which are transmitted to the dust accumulation point through the air medium, causing the dust to fatigue and peel off, thereby achieving the purpose of cleaning. It is a relatively mature technology and will not be described in detail here. A connecting pipe 6 is installed at its output end, which is connected to the loudspeaker 5 through a sealing mechanism. As for the loudspeaker 5, it is assembled on the side wall of the boiler body 1 (only a part of the figure is shown, it is a relatively mature technology and will not be described in detail here), which can facilitate the removal of dust accumulated in the boiler.

[0026] See also Figure 1-Figure 5 In order to facilitate the assembly and use of the sonic soot blower body 2 and to facilitate maintenance operations, the operation can be completed without climbing. A mounting plate 3 is welded on the side wall of the boiler body 1. A motor 8 of a lifting mechanism is installed on the mounting plate 3. The output end of the motor 8 is fixedly mounted with a rotating shaft 9 through a coupling. The end of the rotating shaft 9 is connected to the mounting plate 3 through a bearing seat to ensure stability during rotation. A rope reel 10 is installed on the outside of the rotating shaft 9, on which a hanging rope 12 of a connecting assembly is wound and reeled. One end of the hanging rope 12 passes through the mounting plate 3 and extends to the bottom and is connected to a connecting ring 13. The connecting ring 13 is welded and fixed to the top of the sonic soot blower body 2, which can be conveniently rotated forward and backward by the motor 8, and the rope reel 10 on the rotating shaft 9 is rotated. The bottom end of the sonic sootblower body 2 is welded with a plug-in plate 7 adapted to the plug-in slot 14, which can facilitate auxiliary positioning. At the same time, it does not affect its descending operation when the sonic sootblower body 2 is lowered.

[0027] See also Figure 1-Figure 5In order to facilitate the connection between the connecting pipe 6 and the loudspeaker 5 during use, ensure the sealing during use, and facilitate the lowering of the sonic soot blower body 2, the separation of the two, and the maintenance or replacement of the sonic soot blower body 2, a sealing ring 20 of a sealing mechanism is bonded to the end of the connecting pipe 6, and a sealing groove 17 adapted to the sealing ring 20 is opened at the corresponding position of the end of the loudspeaker 5. In order to facilitate splicing and sealing, the two are also connected by a guide assembly, which includes a connecting plate 16 welded to the end of the connecting pipe 6 and the loudspeaker 5 respectively, wherein the side wall of the connecting plate 16 on the connecting pipe 6 is symmetrically welded with a guide plate 18, and the side wall of the connecting plate 16 on the loudspeaker 5 is symmetrically opened with a guide groove 19 matching the guide plate 18.

[0028] In order to facilitate understanding of the above technical solutions of the present invention, the working principle or operation method of the present invention in actual process is described in detail below.

[0029] In summary, with the aid of the above technical solution of the present invention, the motor 8 rotates forward, which can drive the rotating shaft 9 and the rope reel 10 to rotate, and then the rope 12 can be wound up, which can drive the sonic sootblower body 2 to be lifted and moved upward, and then as it moves upward, the guide rod 11 thereon is inserted into the sliding hole of the mounting plate 3, which can be guided and positioned, and as it continues to move upward, the guide plate 18 on the connecting plate 16 slides with the guide groove 19, and then the plug-in plate 7 is inserted into the plug-in groove 14, and the elastic pad 15 is cooperated for auxiliary positioning, and at the same time the sealing ring 20 is adapted to seal the sealing groove 17, After completing the connection between the connecting pipe 6 and the loudspeaker 5, the sonic soot blower body 2 can work to remove the ash from the boiler body 1. When maintenance operations are required, the motor 8 can be rotated in the opposite direction to pay out the rope 12. The sonic soot blower body 2 moves downward under the action of its own gravity and can be lowered. The sealing ring 20 is separated from the sealing groove 17, and the connecting pipe 6 moves downward together. The sonic soot blower body 2 can be lowered to a suitable height, which makes it convenient to perform maintenance or replacement operations, is convenient for staff to operate, does not require high-altitude operations, and is relatively safe.

[0030] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
