Description

Technical Field

[0001] The utility model relates to the technical field of flue soot blowing, in particular to a high-efficiency flue soot blowing device. Background Art

[0002] During long-term operation of the boiler, a large amount of dust and particulate matter will accumulate on its heating surfaces (such as superheaters, reheaters, economizers, air preheaters, etc.). These dust deposits will significantly reduce the heat transfer efficiency of the heating surfaces because the thermal conductivity of dust is much lower than that of the metal pipe wall, resulting in obstructed heat transfer, thereby affecting the overall operating efficiency of the boiler.

[0003] Dust accumulation not only affects heat transfer, but also creates thermal resistance on the heated surface, causing the metal temperature of the heated surface to rise, aggravating thermal stress, and further accelerating equipment aging, such as deformation, cracking, and cracking, increasing maintenance and replacement costs.

[0004] The traditional method is mostly to blow soot by setting a fixed soot blower. However, since the soot blower is fixed, the cleaning action is relatively simple, the cleaning is not uniform, and there are blind spots in cleaning. Utility Model Content

[0018] Compared with the existing technology, this utility model provides a high-efficiency flue soot blowing equipment with the following features:

[0019] Beneficial effects:

[0020] 1. This high-efficiency flue soot blowing equipment can drive the roller to rotate through the rotating bifurcated pipe. The roller will move from the lowest point of the inclined surface of the inclined disk to the highest point over and over again. This can enable the connecting rod to be driven by the roller to move up and down continuously, so that multiple jet pipes can rotate and swing synchronously. The started compressed air pump can supply gas to the rotating bifurcated pipe through the rotary joint. The compressed air will flow from the bifurcated pipe into the multiple jet pipes and finally be ejected from the jet head to the inner wall of the flue, thereby blowing off the soot on the inner wall of the flue. The fallen soot will fall from the conical groove into the collection box below it for collection. Compared with the traditional fixed jet cleaning method, there are often blind spots in cleaning.

Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

Both ends of the jet pipe 5 are fixedly connected to a jet head. The outer surface of the jet pipe 5 is fixedly connected to two fixed columns.

[0029] A plurality of fixed columns are rotatably connected to corresponding connecting rods 9, the lower end of the connecting rod 9 is fixedly connected to a roller seat 10, and a roller 11 is rotatably connected in the roller seat 10;

[0030] The inclined plate 12 is rotatably connected to the outer surface of the bifurcated pipe 4 , and the roller 11 is adapted to the inclined surface of the inclined plate 12 . The inclined plate 12 is used to drive the roller 11 to move reciprocally up and down.

[0031] Furthermore, the fixed plate 14 is fixedly sleeved on the outer surface of the tilting plate 12 , and a plurality of tapered grooves 15 are evenly arranged on the fixed plate 14 in a circumferential array, and the tapered grooves 15 pass through the lower surface of the fixed plate 14 .

[0032] Furthermore, a tension spring fixing frame 7 is fixedly connected to the upper end of the bifurcated pipe 4, and a tension spring 8 is fixedly connected between the tension spring fixing frame 7 and the upper jet pipe 5, and the tension spring 8 is used to drive the connecting rod 9 to continuously move downward.

[0033] Furthermore, a collecting box 13 is movably mounted on the lower surface of the fixed disk 14 , and the conical groove 15 is used to drop smoke and dust. The motor 2 is fixedly mounted on the support frame 1 , and the output shaft of the motor 2 is fixedly inserted into the bifurcated pipe 4 .

[0034] Furthermore, a rotary joint 16 is sleeved on the lower end of the bifurcated pipe 4, and a compressed air pump 3 for providing compressed air is fixedly installed on the outer surface of the support frame 1. The air outlet end of the compressed air pump 3 is connected to the rotary joint 16, and the rotary joint 16 is used to supply air to the rotating bifurcated pipe 4.

[0035] Furthermore, the output end of the lifting push rod 6 is fixedly connected to the lower surface of the support frame 1, and the lifting push rod 6 is used to drive the entire device to move upward to a position suitable for the flue outlet.

[0036] Furthermore, when in use, the device is placed at the lower end outlet of the flue, and then the lifting push rod 6 is started. The output end of the lifting push rod 6 drives the support frame 1 and the equipment thereon to move upward, so that the conical groove 15 can gradually contact the lower end of the flue. At this time, since the conical groove 15 has a large friction force when contacting the flue wall, the fixed plate 14 will be fixed to the inclined plate 12 and the collection box 13 thereon. By starting the motor 2, the output shaft of the motor 2 drives the bifurcated pipe 4 to rotate, and the rotating bifurcated pipe 4 can rotate together with the multiple jet pipes 5 thereon;

[0037] At this time, the tension spring 8 drives one end of the upper air jet pipe 5 to rotate upward, and under the action of the connecting rod 9 at the other end, it can drive multiple air jet pipes 5 to rotate upward at the same time. At this time, the roller 11 will be continuously attached to the inclined surface of the inclined plate 12;

[0038] The rotating bifurcated pipe 4 can drive the roller 11 to rotate, and the roller 11 will move from the lowest point of the inclined surface of the inclined plate 12 to the highest point over and over again, which can make the connecting rod 9 driven by the roller 11 to move up and down continuously, so that the multiple jet pipes 5 can rotate and swing synchronously, and the started compressed air pump 3 can supply air to the rotating bifurcated pipe 4 through the rotary joint 16, and the compressed air will flow from the bifurcated pipe 4 into the multiple jet pipes 5, and finally be ejected from the jet head to the inner wall of the flue, thereby The soot is blown down and falls from the conical groove 15 into the collection box 13 below it for collection. Compared with the traditional fixed jet cleaning method, there are often blind spots in cleaning. The device makes the conical groove 15 in close contact with the lower end of the flue through the lifting push rod 6, and uses the rotating bifurcated pipe 4 to drive multiple jet pipes 5 to rotate and swing synchronously, so that the ejected gas can cover the inner wall of the flue more widely, thereby improving the uniformity and efficiency of cleaning, effectively avoiding these blind spots and ensuring the comprehensive cleaning of the inner wall of the flue.

[0039] Furthermore, the soot blowing assembly can make multiple jet pipes 5 rotate and swing back and forth while rotating in the flue, which can make the gas ejected from the nozzle act more evenly on the inner wall of the flue, so that the soot on the inner wall of the flue can be cleaned more evenly.

[0040] Working principle: When in use, the device is placed at the lower end of the flue outlet, and then the lifting push rod 6 is started. The output end of the lifting push rod 6 drives the support frame 1 and the equipment thereon to move upward, so that the conical groove 15 can gradually contact the lower end of the flue. At this time, due to the large friction force generated by the set conical groove 15 when contacting the flue wall, the fixed plate 14 will be fixed to the inclined plate 12 and the collection box 13 thereon. By starting the motor 2, the output shaft of the motor 2 drives the bifurcated pipe 4 to rotate, and the rotating bifurcated pipe 4 can rotate together with the multiple jet pipes 5 thereon;

[0041] At this time, the tension spring 8 drives one end of the upper air jet pipe 5 to rotate upward, and under the action of the connecting rod 9 at the other end, it can drive multiple air jet pipes 5 to rotate upward at the same time. At this time, the roller 11 will be continuously attached to the inclined surface of the inclined plate 12;

[0042] When the rotating bifurcated pipe 4 drives the roller 11 to rotate, the roller 11 will move from the lowest point of the inclined surface of the inclined plate 12 to the highest point, over and over again. This enables the connecting rod 9 to be driven by the roller 11 to continuously move up and down, so that the multiple jet pipes 5 can rotate and swing synchronously, and the started compressed air pump 3 can supply air to the rotating bifurcated pipe 4 through the rotary joint 16. The compressed air will flow from the bifurcated pipe 4 into the multiple jet pipes 5, and finally be ejected from the nozzle to the inner wall of the flue, thereby blowing off the soot on the inner wall of the flue. The fallen soot will fall from the conical groove 15 into the collection box 13 below it for collection.
