Description

Technical Field

[0001] The utility model relates to the field of sonic wave dust cleaning, and more specifically to a sonic wave dust cleaning device. Background Art

[0002] The sonic ash cleaner mainly uses sonic waves to clean impurities such as ash attached to the inside of the boiler. The frequency of the sound waves generated by the sonic ash cleaner is the same as the natural frequency of the ash in the boiler, so the ash in the boiler can be peeled off and fall off.

[0003] In order to increase the energy of sound waves, most existing sonic dust cleaners have thickened the diaphragm thickness to increase the amplitude and energy of sound wave vibrations. However, this is accompanied by a higher driving pressure of the sounding disc. Compressed air of about 0.5 MPa or above is required to drive the sonic dust cleaning device. In order to prevent the diaphragm from breaking under long-term compressed air drive, an exhaust port is installed on the top of the sounding disc to achieve pressure relief. However, the above design will cause the sonic dust cleaner to consume more gas and energy. At the same time, the existing sonic dust cleaning device has a complex structure and is not easy to process and produce, and the cleaning quality cannot be guaranteed.

[0004] Therefore, how to provide an acoustic wave dust cleaning device that can overcome the above problems is an issue that those skilled in the art urgently need to solve. Utility Model Content

[0030] Example

[0031] See attached Figure 1-5 The figure is a schematic diagram of the overall and partial structures of an embodiment of the present invention. The present invention specifically discloses an acoustic wave dust cleaning device, including:

[0032] Sounding disc 01 is cylindrical and has coaxial sound holes 010 extending through both ends thereof. Sound holes 010 are circular holes. A circular groove 011 is coaxially formed on one end face of sounding disc 01. An annular groove 012 is coaxially formed on the bottom wall of groove 011. Annular groove 012 is coaxially arranged with sound hole 010. An abutment ring 013 is integrally formed on the bottom wall of groove 011. Abutment ring 013 is coaxially arranged inside annular groove 012. An air inlet 014 is provided on the side wall of sounding disc 011 and communicates with annular groove 012.

[0033] End cap 02, a circular end cap 02, is sealed and buckled onto the end of the sounding disc 01 having the annular groove 012. A second abutment ring 020 is integrally formed on the end of the end cap 02 closest to the sounding disc 01. A second abutment ring 020 is located outside the first abutment ring 013 and the two are coaxially arranged. End cap 02 is provided with air holes 021 extending through both ends thereof, and the air holes 021 are located inside the second abutment ring 020.

[0034] The elastic diaphragm 03 is arranged in the groove 011, and the second abutment ring 020 is located inside the outer contour of the elastic diaphragm 03. The two end surfaces of the elastic diaphragm 03 can be sealed and tightly attached to the first abutment ring 013 and the second abutment ring 020 respectively;

[0035] The bell tube 04, the small-diameter end of the bell tube 04 is connected to the sound plate 01, and the small-diameter end of the bell tube 04 is connected to the sound hole 010; the large-diameter end of the bell tube 04 can extend into the boiler through the boiler entrance or the preset inlet and outlet channel on the boiler;

[0036] A three-way pipe 05, wherein a first connection end of the three-way pipe 05 is connected to the air inlet 014, and a second connection end of the three-way pipe 05 is connected to an external high-pressure air source;

[0037] The pressure regulating valve 06 has one end connected to the third connection end of the three-way pipe 05 , and the other end connected to the air hole 021 through the air pipe 07 .

[0038] The bottom wall of the groove 011 is coaxially provided with a giveway groove 015, which is located on the inner side of the abutment ring 013, and the sound outlet hole 010 passes through the bottom wall of the giveway groove 015; when the elastic diaphragm 03 vibrates, the giveway groove 015 can give way to the elastic diaphragm 03, that is, the bottom wall of the groove 011 will not interfere with the vibration of the elastic diaphragm 03. When the elastic diaphragm 03 vibrates, the middle area of ​​the elastic diaphragm 03 can smoothly undergo elastic deformation, and at the same time, the generated sound waves can be effectively transmitted from the sound outlet hole 010.

[0039] The bell tube 04 includes a bell tube 1 040 and a bell tube 2 041. The small-diameter end of the bell tube 1 040 is connected to the sound plate 01, and the small-diameter end of the bell tube 1 040 is communicated with the sound outlet 010; the small-diameter end of the bell tube 2 041 is coaxially fixed and communicated with the large-diameter end of the bell tube 1 040, and the outer diameter of the end face of the small-diameter end of the bell tube 2 041 is the same as the outer diameter of the end face of the large-diameter end of the bell tube 1 040; the large-diameter end of the bell tube 2 041 can extend into the interior of the boiler from the inlet of the boiler or the preset inlet and outlet channel on the boiler; on the one hand, the bell tube 1 040 and the bell tube 2 041 are both detachable, and whether to install the bell tube 2 041 can be selected according to the size specifications of different boilers; on the other hand, the combination of the bell tube 1 040 and the bell tube 2 041 can improve the cleaning effect of the cleaning device.

[0040] More specifically, it also includes a connecting ring 08, one end of which is coaxially fixed to the small-diameter speaker tube 040, and the other end of the connecting ring 08 is fixed to the end of the sound plate 01 away from the end cover 02, and the sound hole 010 is located on the inner side of the connecting ring 08; the speaker tube 040 and the sound plate 01 can be reliably fixed together.

[0041] When the ash cleaning device is working, an external high-pressure gas source enters the annular groove 012 through the three-way pipe 05. In the initial state, the elastic diaphragm 03 is in close contact with the abutment ring 1 013 and the abutment ring 2 020. As the air pressure in the annular groove 012 increases, the elastic diaphragm 03 will undergo elastic deformation, and the gas in the annular groove 012 will enter the yield groove 015 and the sound outlet 010. At this time, the air pressure in the annular groove 012 decreases, and the elastic diaphragm 03 returns to its original position. However, as the air pressure in the annular groove 012 continues to increase, the elastic diaphragm 03 will undergo elastic deformation again, and the above process is repeated, thereby realizing the vibration and sound generation of the elastic diaphragm 03. The sound waves are amplified by the trumpet tube 1 040 and the trumpet tube 2 041 and then transmitted to the boiler. The frequency of the above sound waves is the same as the natural frequency of the ash, so that the ash attached to the inner wall of the boiler falls off.

[0042] The elastic diaphragm 03 is in close contact with the abutment ring 2 020, and the elastic module and the abutment ring 2 020 form a closed space, and the air hole 021 is connected to the closed space; while the external high-pressure air source inflates the inside of the annular groove 012, the external high-pressure air source is also connected to the air hole 021, and the gas from the external high-pressure air source enters the above-mentioned closed space after being regulated by the pressure regulating valve 06, thereby giving the elastic diaphragm 03 a certain pressure. This design will make the sound waves emitted by the above-mentioned elastic diaphragm 03 stronger when it vibrates, and at the same time, it can also reduce the air supply pressure that drives the cleaning device. The specific reason is that the above-mentioned design will make the elastic diaphragm 03 reset faster, and the energy of the reset action is greater, so the sound waves emitted are stronger; after giving the elastic diaphragm 03 a certain pressure, since it will make the elastic diaphragm 03 reset faster, the elastic diaphragm 03 and the abutment ring 1 013 can close quickly, and at the same time, it can also make the elastic diaphragm 03 and the abutment ring 1 013 contact more tightly and tightly, thereby reducing the waste of compressed air, so there is no need for too high a pressure to ensure the flow supply of compressed air.

[0043] The various embodiments in this specification are described in a progressive manner, and each embodiment focuses on the differences from other embodiments. The same or similar parts between the various embodiments can be referenced to each other.

[0044] The above description of the disclosed embodiments will enable one skilled in the art to implement or use the present invention. Various modifications to these embodiments will be readily apparent to one skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention.
