DETAILED DESCRIPTION

[0032] In order to enable the above-mentioned purposes, features and advantages of the present application to be more clearly understood, the present application will be further described below with reference to the drawings and specific embodiments. It should be noted that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.

[0033] In the following description, many specific details are set forth in order to provide a thorough understanding of the present application, but the present application can also be implemented in other ways different from those described herein, therefore, the protection scope of the present application is not limited by the specific embodiments disclosed below.

[0034] The following refers to Figures 1 to 2 Some embodiments of the present application are described.

[0035] As Figure 1 shown, the embodiments of the present application provide a sound wave soot blower for a folded flame angle, which comprises a number of cylinders 1, a sound transmission assembly, an air transmission assembly and a limiting assembly.

[0036] Specifically, the sound transmission assembly is connected to the number of cylinders 1 at one end; the air transmission assembly is connected to the sound transmission assembly at one end and the other end of the air transmission assembly is used to connect to a gas source; the limiting assembly is connected to the sound transmission assembly at one end and connected to the air transmission assembly at the other end.

[0037] When the whole device starts to work, the air transmission assembly and the sound transmission assembly are in a disconnected state, and the high-intensity sound wave generated by the sound transmission assembly is radiated into the folded flame angle of the boiler, the sound wave propagates and oscillates in the folded flame angle of the boiler, driving the ash particles in the flue gas to vibrate synchronously, so that the accumulated ash on the heating surface is destroyed and peeled off, thereby achieving the effect of removing the accumulated ash at the folded flame angle. At the same time, the gas source transmits high-pressure gas into the air transmission assembly, when the pressure in the air transmission assembly reaches a certain pressure, the air transmission assembly and the sound transmission assembly become connected, the high-pressure gas passes through the air transmission assembly into the sound transmission assembly, and finally the gas is sprayed from the sound transmission assembly, the gas flow generated by the sprayed gas can blow the soot in the folded flame angle, and the peeled off accumulated ash can be scattered, thereby achieving the effect of removing the accumulated ash.

[0038] When the device is not needed, the limiting of the limiting assembly can prevent the dust in the folded flame angle from entering the sound generator 3, and prevent the sound generator 3 from being damaged.

[0039] As Figure 1 shown in the utility model one embodiment, the sound transmission assembly includes sound transmission pipeline 2, one end is connected with the horn 1;Sound generator 3, one end is connected with the other end of the sound transmission pipeline 2.

[0040] The air transmission assembly includes first air transmission pipeline 4, one end is connected with the other end of the sound generator 3;Second air transmission pipeline 5, one end is connected with the other end of the first air transmission pipeline 4;Third air transmission pipeline 6, one end is connected with the other end of the second air transmission pipeline 5, the other end of the third air transmission pipeline 6 is used to connect the air source;First valve 8 is arranged on the third air transmission pipeline 6.

[0041] The limiting assembly includes second valve 9, which is arranged on the sound transmission pipeline 2;Fourth air transmission pipeline 7, one end is connected with the second valve 9, the other end is connected with the third air transmission pipeline 6.

[0042] When the whole device starts to work, the first valve 8 installed on the third air transmission pipeline 6 and the second valve 9 installed on the sound transmission pipeline 2 are in closed state, the first valve 8 adopts electromagnetic valve, the second valve 9 adopts pneumatic knife valve, then the air source transmits high pressure gas into the third air transmission pipeline 6, part of the gas in the third pipeline enters the fourth air transmission pipeline 7, and then as the gas in the third air transmission pipeline 6 and the fourth air transmission pipeline 7 gradually increases, when the air pressure increases to a certain value, the electromagnetic valve and the pneumatic knife valve are in open state, and then the high pressure gas enters the second air transmission pipeline 5, the first air transmission pipeline 4, the sound generator 3, the sound transmission pipeline 2 and the horn 1 in turn after passing through the electromagnetic valve, the high pressure gas is sprayed out of the horn 1, and the airflow generated after the high pressure gas is sprayed out of the horn 1 can clean the dust on the fold angle.

[0043] At the same time, the high intensity sound wave generated by the sound generator 3 enters the sound transmission pipeline 2, and then is emitted from the horn 1, the high intensity sound wave emitted from the horn 1 can be radiated into the boiler fold angle, the sound wave propagates and oscillates in the boiler fold angle, drives the ash particles in the flue gas to vibrate synchronously, and the accumulated ash on the heating surface is destroyed and peeled off, so that the effect of removing the accumulated ash at the fold angle is realized. Under the cooperation of the airflow, the peeled off accumulated ash can be cleaned. The horn 1 adopts exponential horn 1, the sound pressure level of the sound wave one meter away from the exponential horn 1 is not less than 160dB, so that the sound wave can cover the whole heating surface during the propagation process in the fold angle, and the accumulated ash can be stably removed and reduced.

[0044] When the device is not needed, the air source can stop providing high pressure gas, the air pressure in the third air transmission pipeline 6 cannot meet the working requirement, and then the electromagnetic valve and the pneumatic knife valve are closed, after the pneumatic knife valve is closed, the dust in the fold angle cannot pass through the sound transmission pipeline 2 and enter the sound generator 3, so as to protect the parts.

[0045] In addition, the opening and closing of the electromagnetic valve is controlled by the PLC, and then the opening time of the electromagnetic valve can be controlled by the PLC to control the ventilation time of the whole device, thereby reducing the dependence on people, and the PLC controls the electromagnetic valve, which is prior art, and the principle will not be described in detail.
