Description

Technical Field

[0001] This utility model relates to the field of acoustic soot remover technology, specifically an acoustic soot remover for pulverized coal boilers. Background Technology

[0002] The sonic dust cleaner is an instrument used to clean dust. This equipment is widely used in electrostatic precipitators, bag filters, cyclone dust collectors, and in places where there is material accumulation and poor flow in gypsum silos, lime silos, cement silos, and other material silos, to remove dust, honeycomb holes, bridging, or blockages on the surface of various material silos.

[0003] Existing dust removal devices have shortcomings. When adjusting the sound wave amplitude, it's difficult to easily change the sound wave propagation channel area, making it impossible to simply and efficiently adjust the dust removal sound wave size. This results in poor dust removal performance and poor adaptability to different working environments. It cannot flexibly release appropriately sized sound waves according to requirements, affecting the device's dust removal efficiency under various operating conditions. Utility Model Content

This changes the degree of obstruction of the air outlet by the blocking arm. By changing the position of the blocking arm, the area of ​​the sound wave propagation channel is changed, thereby controlling the sound wave magnitude.

Operators adjust the throttle valve as needed to change the amount of gas entering the generator housing. The throttle valve is made entirely of metal, such as stainless steel or brass, to ensure its durability under high temperature and high pressure conditions. The compressed air vibrates against a high-strength titanium alloy diaphragm inside the generator housing to generate sound waves for subsequent work. The design of this component allows for control of the air volume during intake. When used in conjunction with the baffle regulating component, it greatly improves the efficiency of the device.

[0024] This utility model provides the following technical solution:

[0025] Example 1

[0026] Please see Figure 1-5An acoustic soot remover for pulverized coal boilers includes a loudspeaker section 1, a loudspeaker section 2 3 at the left end of the loudspeaker section 1, a soot removal port 4 fixedly connected to the left end of the loudspeaker section 2 3, a soot removal mechanism 5 on the surface of the loudspeaker section 1, the loudspeaker section 2 3 and the soot removal port 4, the soot removal mechanism 5 including an air intake adjustment component 51 and a baffle adjustment component 52, and a stable support mechanism 6 on the surface of the loudspeaker section 1 and the loudspeaker section 2 3.

An air vent 522 is provided on the surface of the built-in fixing plate 521. A support frame 523 is fixedly connected to the left end of the built-in fixing plate 521. A mounting box 525 is fixedly connected to the inner end of the support frame 523. A passage 524 is provided on the surface of the support frame 523. A first bevel gear 526 is provided at the top inside the mounting box 525. A connecting shaft 527 is provided at the top of the first bevel gear 526. A rotating handle 528 is fixedly connected to the top of the connecting shaft 527. A second bevel gear 529 is installed at the right end inside the mounting box 525. A rotating shaft 5201 is provided at the right end of the second bevel gear 529. A back plate 5202 is fixedly connected to the right end of the rotating shaft 5201. A baffle arm is fixedly connected to the surface of the back plate 5202. 5203, A sound wave magnitude monitor 5204 is installed on the top surface of the dust removal port 4. When compressed air generates sound waves through the air intake regulating component 51 and transmits them through the second section 3 of the sound amplification tube, the operator rotates the rotating handle 528 to drive the connecting shaft 527 and the first bevel gear 526 to rotate, which in turn drives the second bevel gear 529, the rotating shaft 5201 and the back plate 5202 to rotate, changing the degree of obstruction of the blocking arm 5203 to the air port 522. By changing the position of the blocking arm 5203, the channel area for sound wave propagation is changed, thereby controlling the sound wave magnitude. With the sound wave magnitude monitor 5204 for detection, the operator can release sound waves of different magnitudes according to different needs to meet the work requirements, which greatly improves the dust removal effect of the device and improves the adaptability of the device to different working environments.

A throttle valve 514 is installed on the surface of the air intake pipe 513, and a connecting pipe 515 is installed on the outer end of the throttle valve 514. A sealing ring 516 is installed between the air intake pipe 513, the throttle valve 514, and the connecting pipe 515. An air intake port 517 is fixedly connected to the left end of the inside of the transmitter housing 512, and a high-strength titanium alloy is installed inside the air intake port 517. Compressed air enters the device through the connecting pipe 515 via the gold diaphragm 518. The operator adjusts the throttle valve 514 as needed to change the amount of gas entering the sound generator housing 512. The throttle valve 514 is made entirely of metal, such as stainless steel or brass, to ensure its good durability under high temperature and high pressure. The compressed air vibrates with the high-strength titanium alloy diaphragm 518 inside the sound generator housing 512 to generate sound waves for subsequent work. The design of this component can control the amount of air during intake. When used in conjunction with the baffle adjustment component 52, it greatly improves the efficiency of the device.

[0031] Example 2

[0032] Please see Figure 1-5 Furthermore, based on Embodiment 1, a stable support mechanism 6 is further obtained, comprising a first support ring 61, which is installed at the bottom of the first section 1 of the loudspeaker and the second section 3 of the loudspeaker. A damping telescopic column 63 is fixedly connected to the inner end of the first support ring 61, and a spring 64 is sleeved on the surface of the damping telescopic column 63. A second support ring 65 is fixedly connected to the inner end of the damping telescopic column 63. A support base 66 is fixedly connected to the bottom of the first support ring 61. Side mounting seats 62 are fixedly connected to both the front and back of the first support ring 61.

[0033] A mounting flange 2 is installed between the first section 1 of the loudspeaker and the second section 3 of the loudspeaker, and the first section 1 of the loudspeaker and the second section 3 of the loudspeaker are connected together through the mounting flange 2.

[0034] In actual operation, when this device is in use, compressed air enters the device through the connecting pipe 515. The operator adjusts the throttle valve 514 as needed to change the amount of gas entering the sound generator housing 512. The throttle valve 514 is made of metal, such as stainless steel or brass, to ensure its good durability under high temperature and high pressure. The compressed air vibrates with the high-strength titanium alloy diaphragm 518 inside the sound generator housing 512 to generate sound waves for subsequent work. The design of this component can control the amount of air during intake. When used in conjunction with the baffle adjustment component 52, it greatly improves the efficiency of the device.

[0035] When compressed air generates sound waves through the intake regulating component 51 and transmits them through the second section 3 of the amplifier tube, the operator rotates the rotating handle 528 to drive the connecting shaft 527 and the first bevel gear 526 to rotate, which in turn drives the second bevel gear 529, the rotating shaft 5201, and the back plate 5202 to rotate, changing the degree of obstruction of the air inlet 522 by the blocking arm 5203. By changing the position of the blocking arm 5203, the channel area for sound wave propagation is changed, thereby controlling the size of the sound wave. With the help of the sound wave size monitor 5204, the operator can release sound waves of different sizes according to different needs to meet the work requirements, which greatly improves the ash removal effect of the device and improves the adaptability of the device to different working environments. When the device is installed on the boiler, the damping telescopic column 63 and the spring 64 between the first support ring 61 and the second support ring 65 can ensure the overall stability of the device and prevent the shaking during the sound wave oscillation from affecting the stable installation of the device.
