A ball head collecting structure 6 is provided in the lower arc cover 3, and the upper end of the ball head collecting structure 6 extends out of the upper surface of the lower arc cover 3. A collecting pipe 7 connected to the outside is provided on the side of the lower arc cover 3. The sound wave collecting device 4 and the sound wave vibration device 5 are arranged to absorb the energy in the noise and convert it into power for absorbing and separating dust in the passing airflow, so as to achieve the purpose of energy saving, noise reduction and dust removal.
[0036] In this embodiment, a water inlet pipe 22 connected to the outside is provided on the side of the upper arc-shaped cover 2 , and the water inlet pipe 22 is used to replenish water into the upper arc-shaped cover 2 .
[0037] In this embodiment, a groove 211 is provided at the top of the narrow groove 21, and the groove 211 is an arc-shaped groove. The width of the narrow groove 21 is 0.8-1mm. Water flowing out of the narrow groove 21 within this width range is easy to form water droplets, which are convenient for mixing with air to form water droplets containing bubbles. The bubbles can increase the adsorption capacity for dust by increasing the surface area, thereby improving the efficiency of dust reduction.
[0038] In this embodiment, the sound wave collecting device 4 includes an arc-shaped bottom 43 and a resonance plate 44. The resonance plate 44 is fixed to the side of the arc-shaped bottom 43. An extension rod 45 is provided at the bottom of the resonance plate 44. The resonance plate 44 generates vibrations through the energy in the noise, and the vibrations are transmitted to the extension rod 45. After the water mixed with dust falls onto the lower housing cover 3, the extension rod 45 extends into the water, and the dust precipitation is accelerated through continuous vibration, thereby accelerating the separation of dust and water.
[0039] In this embodiment, the sound wave vibration device 5 also includes a noise vibration diaphragm 53, a sealing tube 54, and a striker 55. The sealing tube 54 is trumpet-shaped as a whole and is filled with helium. The noise vibration diaphragm 53 is fixed to one end of the sealing tube 54 in the shape of a trumpet. The striker 55 is slidably mounted on the sealing tube 54 and is connected to the noise vibration diaphragm 53 through a connecting rod 56 on the inside. The striker 55 extends out of the sealing tube 54 and is connected to a plurality of vibration plates 51 at equal intervals on the outside. The vibration plates 51 and the sponge plates 52 are connected to each other. The sponge layer is tightly attached, the sponge board 52 is fixedly mounted on the cover body 58, the cover body 58 is mounted in the upper arc cover 2, the sponge board 52 is provided with a limiting frame 521, the vibration plate 51 is located in the limiting frame 521, and the noise is transmitted to the noise vibration diaphragm 53 to generate high-frequency vibration, and the vibration is transmitted to the striker 55 through the connecting rod 56. The high-frequency vibration of the striker 55 drives the vibration plate 51 to continuously circulate and squeeze the sponge layer in the sponge board 52, so that air can be mixed into the water in the sponge layer.
[0040] In this embodiment, the ball head collection structure 6 includes a protective cover 61, a water level sensor 62, a ball head 63, a connecting pipe 64 and a floating head 65. The protective cover 61 covers the water level sensor 62, and the water level sensor 62 is fixedly mounted on the ball head 63. The ball head 63 is mounted on the connecting pipe 64. A mounting plate 66 is provided on the outer side of the connecting pipe 64. The mounting plate 66 is mounted on the upper surface of the lower arc cover 3. The bottom of the connecting pipe 64 is connected to the floating head 65 and passes through the floating head 65. The ball head 63 is a hollow structure. A plurality of through holes are provided on the ball head 63. As the dust is mixed with the water droplets, the water droplets are collected. The dust falls on the lower arc cover 3 and accumulates continuously, the water surface gradually rises, and under the action of the extension rod and the resonance plate 44, the dust is separated from the water and settles to the bottom, and the upper water touches the water level sensor 62. According to the feedback of the water level sensor 62, the collection pipe 7 is controlled to suck, and the water is sucked into the lower arc cover 3 through the ball head at the top. At the same time, as the water in the lower arc cover 3 gradually increases, it will contact the floating head 65. The buoyancy of the floating head 65 makes the entire ball head collection structure 6 float up, avoiding the water level sensor 62 from misjudging the water volume due to the accumulation of dust, and at the same time avoiding the through hole on the ball head 63 from being blocked by dust.
[0041] Working principle: first connect the connecting pipe 1 to the production equipment, and then introduce air flow. The noise will be transmitted to the noise vibration diaphragm 53 to generate high-frequency vibration, and the vibration will be transmitted to the striker 55 through the connecting rod 56. The high-frequency vibration of the striker 55 drives the vibration plate 51 to continuously circulate and squeeze the sponge layer in the sponge plate 52, so that air can be mixed into the water in the sponge layer. The air bubbles can increase the dust adsorption capacity by increasing the surface area. When the water falls into the air flow passing area between the upper arc cover 2 and the lower arc cover 3, it will adsorb the dust in the gas and settle on the lower arc cover 3. The resonance plate 44 is driven to vibrate by the energy in the noise, and the vibration will be transmitted to the extension rod 45. After the water mixed with dust falls on the lower arc cover 3, the extension rod 45 is extended into the water, and the dust is accelerated to settle through continuous vibration. The dust is separated from the water by the water droplets, and the dust is separated from the water and precipitated to the bottom. The water on the upper layer touches the water level sensor 62. The collection pipe 7 is controlled to suck water into the lower arc cover 3 through the ball head at the top according to the feedback of the water level sensor 62. At the same time, as the water in the lower arc cover 3 gradually increases, it contacts the floating head 65. The buoyancy of the floating head 65 makes the entire ball head collection structure 6 float, so as to avoid the accumulation of dust affecting the water level sensor 62 to misjudge the water volume, and to avoid the through hole on the ball head 63 being blocked by dust. According to actual needs, several basic devices can be set in the connecting pipe 1 to increase the effect of dust removal and noise reduction.
[0042] Based on the above, the present invention is provided with a sonic vibration device to cooperate with the continuously seeping water, which can inject air into the water to form tiny bubbles driven by the energy in the noise, increase the adsorption effect of water on dust in the airflow, and increase the dust removal effect. At the same time, due to the utilization of energy in the noise, it can effectively reduce noise and achieve the purpose of noise reduction. After the water adsorbing dust falls on the lower arc cover, the set sonic collection device can be driven to vibrate synchronously by the noise, and the water mixed with dust is vibrated by the extension rod, and the precipitation speed of solid particles such as dust in the water is accelerated by vibration, thereby accelerating the separation of water and dust, and then the separated water is recovered, which can prevent excessive water from blocking the pipeline, increase the utilization rate of water, and consume energy in the noise at the same time, achieving the purpose of noise reduction and dust removal. The present invention effectively removes dust and reduces noise.
[0043] The present invention is described above by way of example in conjunction with the accompanying drawings. It is obvious that the specific implementation of the present invention is not limited to the above-mentioned method. As long as various non-substantial improvements are made using the inventive concept and technical solution of the present invention, or the inventive concept and technical solution are directly applied to other occasions without improvement, they are all within the protection scope of the present invention.
