Description

Technical Field

[0001] The utility model relates to the technical field of furnace sootblowing, in particular to a furnace sootblower. Background Art

[0002] A furnace soot blower is an instrument used to remove accumulated soot from the heating surface of a boiler furnace. The internal space of the furnace is large, and the heating surfaces are often not distributed on the same plane, but at different heights and angles. The soot blower cannot be raised or lowered and can only blow at a fixed position, which may cause excessive blowing of certain parts, resulting in wear and damage to the heating surface. The lifting function can accurately control the position and strength of the soot blowing to avoid unnecessary damage to the heating surface.

[0003] Chinese patent authorization announcement number: CN217154202U, provides a furnace soot blower, which facilitates the fixed installation of the soot blower body in an appropriate working position through the provided mounting ears and the action of the mounting bolts, and the soot blower pipe extends to the inside of the boiler and is connected to the boiler. When the soot blower body is started, the compressed air is converted into high-power sound waves or infrasound waves and sent into the boiler through the soot blower pipe. When the ash accumulated on the heating surface of the boiler is repeatedly pulled and pressed by the density waves that alternate at a certain frequency, the ash is loosened due to fatigue and then carried away with the flue gas flow, or under the action of gravity, the ash settles to the ash hopper for discharge. However, the internal space of the furnace is large, and the distribution of the heating surfaces is often not on the same plane, but at different heights and angles. If the position is fixed, it will lead to poor cleaning effect.

[0004] Therefore, it is necessary to provide a furnace soot blower to solve the above technical problems. Utility Model Content

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.

[0022] See also Figures 1 to 4 , a furnace soot blower provided by an embodiment of the present utility model comprises a support and adjustment component 1, a soot blowing component 2 is provided at the upper end of the support and adjustment component 1;

[0023] The support adjustment assembly 1 includes a base shell 101, a plurality of support legs 102 are fixedly connected to the middle of the base shell 101, one end of each of the support legs 102 is fixedly connected to a universal wheel 103, a screw rod 104 is rotatably connected to the middle of the base shell 101, and a lifting rod 105 is rotatably connected to the middle of the screw rod 104 through a thread.

[0024] The upper end of the base housing 101 is fixedly connected to a connecting rod 106 . The upper end of the connecting rod 106 is fixedly connected to a limiting sleeve 107 . The limiting sleeve 107 is slidably connected to the lifting rod 105 .

[0025] A worm gear 108 is fixedly connected to the middle of the screw rod 104 and located inside the base shell 101. A worm 109 is rotatably connected to the inside of the base shell 101, and the worm 109 is meshed with the worm gear 108. One end of the worm 109 is fixedly connected to the outside of the base shell 101 and is located. A rotating handle 110 is fixedly connected.

[0026] The sootblowing assembly 2 includes a sound wave generator 201 fixedly connected to the upper end of the lifting rod 105 , and an annular sound wave emitting end 202 is fixedly connected to the output end of the sound wave generator 201 .

[0027] An internal threaded hole is provided inside the lifting rod 105 , and a plurality of strip-shaped protrusions are fixedly connected to the middle portion of the lifting rod 105 .

[0028] The limiting sleeve 107 has a plurality of strip-shaped grooves formed inside thereof for cooperating with the lifting rod 105 for sliding and limiting.

[0029] When working, the furnace sootblower mainly consists of a support and adjustment component 1 and a sootblowing component 2. The support and adjustment component 1 provides stable support and height adjustment for the entire device, while the sootblowing component 2 is responsible for generating sound waves to clean the soot accumulated in the furnace.

[0030] The multiple support legs 102 fixedly connected to the middle of the base shell 101 serve to support the entire device. The universal wheel 103 at one end of the support leg 102 allows the device to be easily moved to the desired position, facilitating soot blowing operations at different furnaces. Turning the handle 110 drives the worm 109 to rotate. Since the worm 109 is meshed with the worm wheel 108, the rotation of the worm 109 drives the worm wheel 108 to rotate. The worm wheel 108 is fixedly connected to the middle of the screw rod 104. The rotation of the worm wheel 108 causes the screw rod 104 to rotate. The middle of the screw rod 104 is connected to the lifting rod 105 through a threaded rotation. The rotation of the screw rod 104 causes the lifting rod 105 to move up and down on the screw rod 104. The connecting rod 106 at the upper end of the base shell 101 is connected to the limiting sleeve 107. The lifting rod 105 is slidably connected to the limiting sleeve 107. The strip groove inside the limiting sleeve 107 cooperates with the strip protrusion in the middle of the lifting rod 105 to prevent the lifting rod 105 from rotating, ensuring that it can only move up and down linearly.

[0031] When powered, the sootblower assembly 2 generates sound waves of a specific frequency and intensity. These waves are then emitted into the furnace via a ring-shaped sound wave transmitter 202 connected to the sootblower assembly 2. When the sound wave energy reaches the surface of the soot accumulation, it causes the soot particles to vibrate. Because the soot particles typically have a weak bond to the equipment surface, the continued action of the sound waves gradually loosens them and causes them to fall off, effectively removing the accumulated soot.

[0032] Through the height adjustment function of the support adjustment component 1, the annular sound wave emitting end 202 of the sootblowing component 2 can be adjusted to the furnace heating surface area at different heights, thereby achieving comprehensive cleaning of the entire furnace heating surface, effectively preventing local ash accumulation from seriously affecting the heat transfer efficiency of the boiler, and ensuring the stable operation of the boiler.
