Description

Technical Field

[0001] The present invention relates to the technical field of pipeline dust cleaning devices, and particularly to a multi-frequency resonance device for preventing wall hanging and dust accumulation. Background Art

[0002] In many industrial scenarios, such as the flue ducts of thermal power plants and the dust collection pipelines of cement plants, due to a large amount of dust in the gas, dust accumulation is extremely likely to occur on the inner wall of the pipeline; the dust accumulation in the pipeline will not only affect the normal flow of the fluid in the pipeline, increase the resistance during the airflow, reduce the system operation efficiency, but also cause pipeline blockage and trigger safety accidents; therefore, a dust cleaning device needs to be set on the pipeline to prevent pipeline dust accumulation.

[0003] The multi-frequency resonance device for preventing wall hanging and dust accumulation generates sound waves and transmits them into the pipeline wall. The sound waves resonate with the pipeline wall, causing the pipeline wall to vibrate, so that the dust in the pipeline wall falls off from the pipeline wall; the multi-frequency resonance device for preventing wall hanging and dust accumulation uses sound waves of different frequencies to improve the effect of cleaning the dust on the pipeline wall.

[0004] The effective dust cleaning distance of sound waves with high sound power in the pipeline wall is 10 to 15 meters. However, if the pipeline is bent, the sound waves need to be reflected and refracted multiple times when propagating in the pipeline, which will consume the energy of the sound waves and shorten the effective propagation distance of the sound waves to about 5 meters. As a result, the dust cleaning effect of the multi-frequency resonance device for preventing wall hanging and dust accumulation is limited, thus causing limitations.

[0005] Therefore, we propose a multi-frequency resonance device for preventing wall hanging and dust accumulation. Summary of the Invention

[0006] Aiming at the deficiencies of the prior art, the present invention provides a multi-frequency resonance device for preventing wall hanging and dust accumulation, which overcomes the deficiencies of the prior art and aims to solve the problems in the background art.

[0007] To achieve the above object, the present invention provides the following technical solutions: A multi-frequency resonance device for preventing wall hanging and dust accumulation, comprising:

[0008] A multi-frequency sound wave resonance mechanism, a propagation pipe, and a connection seat; the propagation pipe is in a horn shape, with one end having a large size and the other end having a small size; the multi-frequency sound wave resonance mechanism is connected to the small-diameter end of the propagation pipe; the connection seat is connected to the large-diameter end of the propagation pipe through a connection mechanism, and the connection seat is installed on the pipeline wall.

[0009] When the propagation pipe, the multi-frequency sound wave resonance mechanism, and the connection seat are installed on the pipeline, they form an acute angle with the pipeline.

[0010] Preferably, the connecting mechanism includes a first connecting ring, a second connecting ring and a fixing pin; the first connecting ring is fixedly connected to the propagation pipe; the second connecting ring is fixedly connected to the connecting seat; the first connecting ring and the second connecting ring are rotatably connected; the fixing pin is inserted into the first connecting ring and the second connecting ring to fix the first connecting ring and the second connecting ring.

[0011] In the present invention, the connecting seat and the propagation pipe are connected through the first connecting ring and the second connecting ring, and the propagation pipe is inclined. Therefore, the sound waves emitted by the multi-frequency acoustic resonance mechanism enter the pipe obliquely and propagate along one side of the pipe, thereby reducing the dispersion of the sound waves from the other side, improving the effect of the unidirectional propagation of the sound waves in the pipe, and further increasing the distance of the unidirectional cleaning of the sound waves in the pipe.

[0012] Preferably, a telescopic groove is formed on the inner wall of the propagation pipe; a telescopic block is slidably connected in the telescopic groove; a plurality of reflecting plates are uniformly installed on the telescopic block; a telescopic spring is installed in the telescopic groove; the telescopic spring is connected to the telescopic block.

[0013] Preferably, a driving gear ring is fixedly connected inside the second connecting ring; a driving shaft is rotatably connected to the first connecting ring; two ends of the driving shaft are respectively fixedly connected with a driving gear and a winding disc; the driving gear meshes with the driving gear ring; a winding rope is wound around the winding disc; the other end of the winding rope is fixedly connected with the telescopic block.

[0014] Preferably, four notches are formed on the driving gear ring; the notches are equally spaced, and the notches cut off the tooth shape on the driving gear ring.

[0015] By extending the reflecting plate into the pipe, the reflecting plate reflects behind the sound wave, thereby reducing the dispersion of the sound wave from the end where the pipe and the propagation pipe form an acute angle, and improving the effect of making the sound wave propagate in the direction where the pipe and the propagation pipe form an obtuse angle by inclining the propagation pipe and the multi-frequency acoustic resonance mechanism.

[0016] Preferably, the reflecting plates are stacked in a staggered manner, and the reflecting plates are rotatably connected to the telescopic block; a torsion spring is connected between the reflecting plate and the telescopic block.

[0017] Preferably, a converging member is connected to one end of the propagation pipe connected to the first connecting ring; the converging members are symmetrically arranged in the propagation pipe.

[0018] Preferably, the reflecting plate is inclined.

[0019] In the present invention, a converging member is provided inside the propagation pipe. The converging member presses against the reflection plates on both sides. When the reflection plates extend into the pipe, the converging member presses against one end of the reflection plates close to the telescopic block, while the other end of the reflection plates away from the telescopic block opens, making the overall shape of the reflection plates similar to a fan. Thus, it can ensure that when the reflection plates extend into the pipe, they have a large enough reflection surface, and at the same time, it can ensure that the reflection plates can be retracted into the propagation pipe. In the present invention, the reflection plates are inclined, so that when the reflection plates extend into the pipe, there are gaps between the reflection plates, which will not affect the air flow inside the pipe and prevent the ventilation of the pipe from being affected.

[0020] Advantages of the present invention:

[0021] 1. In the present invention, the connection seat and the propagation pipe are connected through the first connection ring and the second connection ring, and the propagation pipe is inclined. Therefore, the sound waves emitted by the multi-frequency sound wave resonance mechanism enter the pipe obliquely and propagate along one side of the pipe, reducing the dispersion of the sound waves from the other side, improving the effect of the one-way propagation of the sound waves in the pipe, and further improving the one-way cleaning distance of the sound waves in the pipe.

[0022] 2. By extending the reflection plates into the pipe in the present invention, the reflection plates reflect the sound waves behind the sound waves, thus reducing the dispersion of the sound waves from the end where the pipe and the propagation pipe form an acute angle, and improving the effect of making the sound waves propagate in the direction where the pipe and the propagation pipe form an obtuse angle by setting the propagation pipe and the multi-frequency sound wave resonance mechanism obliquely.

[0031] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0032] Embodiment 1: Refer to the attached drawings of the specification Figures 1 to 7 , a multi-frequency resonance anti-wall-hanging dust accumulation device, including:

[0033] A multi-frequency acoustic resonance mechanism 1, a propagation tube 2 and a connecting seat 3; the propagation tube 2 is in a horn shape, with a large size at one end and a small size at the other end; the multi-frequency acoustic resonance mechanism 1 is connected to the small-diameter end of the propagation tube 2; the connecting seat 3 is connected to the large-diameter end of the propagation tube 2 through a connecting mechanism, and the connecting seat 3 is installed on the pipe wall of the pipeline;

[0034] When the propagation tube 2, the multi-frequency acoustic resonance mechanism 1 and the connecting seat 3 are installed on the pipeline, an acute angle is formed with the pipeline.

[0035] In the present invention, the connecting mechanism includes a first connecting ring 41, a second connecting ring 42 and a fixing pin 43; the first connecting ring 41 is fixedly connected to the propagation tube 2; the second connecting ring 42 is fixedly connected to the connecting seat 3; the first connecting ring 41 and the second connecting ring 42 are rotatably connected; the fixing pin 43 is inserted into the first connecting ring 41 and the second connecting ring 42 to fix the first connecting ring 41 and the second connecting ring 42.

[0036] In the present invention, the connecting seat 3 is installed on the pipeline by bolts, and in the initial state, the pin fixes the first connecting ring 41 and the second connecting ring 42. When it is necessary to clean the inside of the pipeline, the multi-frequency acoustic resonance mechanism 1 is started, so that the multi-frequency acoustic resonance mechanism 1 emits sound waves. The sound waves propagate in the propagation tube 2, and then pass through the first connecting ring 41, the second connecting ring 42 and the connecting seat 3 and enter the pipeline. Since the propagation tube 2 and the multi-frequency acoustic resonance mechanism 1 of the present invention form an acute angle with the pipeline, after the sound waves enter the pipeline, most of them propagate along the side where the pipeline and the propagation tube 2 form an obtuse angle, thereby reducing the dispersion of the sound waves from the end where the pipeline and the propagation tube 2 form an acute angle. Thus, the sound waves emitted by the multi-frequency acoustic resonance mechanism 1 can propagate unidirectionally farther in the pipeline. The sound waves propagate unidirectionally along the pipeline to clean the pipeline wall hanging;

[0037] When it is necessary to clean the other side of the pipeline, the fixing pin 43 between the first connecting ring 41 and the second connecting ring 42 is pulled out so that the first connecting ring 41 and the second connecting ring 42 can rotate. Then, the propagation tube 2 and the multi-frequency acoustic resonance mechanism 1 are rotated 180 degrees, so that the propagation tube 2 and the multi-frequency acoustic resonance mechanism 1 are inclined towards the other side of the pipeline, and then the uncleaned side of the pipeline will be cleaned;

[0038] In the present invention, the connecting seat 3 and the propagation tube 2 are connected through the first connecting ring 41 and the second connecting ring 42, and the propagation tube 2 is inclined. Therefore, the sound waves emitted by the multi-frequency acoustic resonance mechanism 1 enter the pipeline obliquely and propagate along one side of the pipeline, thereby reducing the dispersion of the sound waves from the other side, improving the effect of the unidirectional propagation of the sound waves in the pipeline, and further improving the distance of the unidirectional cleaning of the sound waves in the pipeline.

[0039] In the present invention, a telescopic groove 4 is opened on the inner wall of the propagation tube 2; a telescopic block 51 is slidably connected in the telescopic groove 4; a plurality of reflecting plates 52 are uniformly installed on the telescopic block 51; a telescopic spring 53 is installed in the telescopic groove 4; the telescopic spring 53 is connected to the telescopic block 51.

[0040] In the present invention, a driving gear ring 54 is fixedly connected inside the second connecting ring 42; a driving shaft 55 is rotatably connected to the first connecting ring 41; two ends of the driving shaft 55 are respectively fixedly connected with a driving gear 56 and a winding disc 57; the driving gear 56 is engaged with the driving gear ring 54; a winding rope 58 is wound on the winding disc 57; the other end of the winding rope 58 is fixedly connected with the telescopic block 51.

[0041] In the present invention, four notches 8 are opened on the driving gear ring 54; the notches 8 are equally spaced, and the notches 8 cut off the tooth shape on the driving gear ring 54.

[0042] In the present invention, when the rotation propagation tube 2 and the multi-frequency acoustic resonance mechanism 1 are rotated, the first connecting ring 41 and the second connecting ring 42 rotate relative to each other, and the driving gear ring 54 drives the driving gear 56 to rotate, so that the driving shaft 55 drives the winding disc 57 to rotate. The winding disc 57 winds the winding rope 58, thereby pulling down the telescopic block 51. The telescopic block 51 stretches the telescopic spring 53. The reflector 52 on the telescopic block 51 passes through the first connecting ring 41, the second connecting ring 42 and the connecting seat 3 and then extends into the pipeline. Thus, the reflector 52 reflects behind the sound wave, reducing the dispersion of the sound wave from the end where the pipeline and the propagation tube 2 form an acute angle, and cooperating with the inclined setting of the propagation tube 2, thereby improving the propagation effect of the sound wave of the present invention from the other end;

[0043] In the present invention, a notch 8 is provided on the driving gear ring 54. When the driving gear 56 rotates to the position of the notch 8, the driving gear 56 disengages from the driving gear ring 54. Under the action of the telescopic spring 53, the telescopic block 51 pulls the reflector 52 back into the propagation tube 2. When the driving gear 56 rotates on the driving gear ring 54 again, it re-engages with the driving gear ring 54, thereby extending the reflector 52 into the pipeline again. Therefore, during the 180-degree rotation of the propagation tube 2 and the multi-frequency acoustic resonance mechanism 1 in the present invention, the reflector 52 is first retracted into the propagation tube 2 and then extended into the pipeline, thus preventing the reflector 52 in the pipeline from affecting the rotation between the first connecting ring 41 and the second connecting ring 42;

[0044] In the present invention, by extending the reflector 52 into the pipeline, the reflector 52 reflects behind the sound wave, thereby reducing the dispersion of the sound wave from the end where the pipeline and the propagation tube 2 form an acute angle, and improving the effect of setting the propagation tube 2 and the multi-frequency acoustic resonance mechanism 1 obliquely so that the sound wave propagates in the direction where the pipeline and the propagation tube 2 form an obtuse angle.

[0045] Embodiment 2: On the basis of Embodiment 1, referring to the attached drawings of the specification Figures 1 to 7 In the present invention, the reflectors 52 are arranged in a staggered and stacked manner, and the reflectors 52 are rotatably connected to the telescopic blocks 51; a torsion spring 6 is connected between the reflectors 52 and the telescopic blocks 51.

[0046] In the present invention, one end of the propagation tube 2 connected to the first connecting ring 41 is connected with a converging member 7; the converging members 7 are symmetrically arranged in the propagation tube 2.

[0047] In the present invention, the reflector 52 is obliquely arranged.

[0048] In the present invention, a converging member 7 is provided in the transmission pipe 2. The converging member 7 presses the reflection plates 52 on both sides. When the reflection plates 52 extend into the pipe, the converging member 7 presses one end of the reflection plate 52 close to the telescopic block 51, while the other end of the reflection plate 52 away from the telescopic block 51 opens, making the overall shape of the reflection plate 52 similar to a sector. Thus, it can not only ensure that the reflection plate 52 has a sufficiently large reflection surface when extending into the pipe, but also ensure that the reflection plate 52 can be retracted into the transmission pipe 2. In the present invention, the reflection plates 52 are inclined, so that when the reflection plates 52 extend into the pipe, there is a gap between the reflection plates 52, which will not affect the air flow in the pipe and prevent the ventilation of the pipe from being affected.

[0049] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited by the above embodiments. The above embodiments and the descriptions in the specification only illustrate the principles of the present invention. Without departing from the spirit and scope of the present invention, the present invention will have various changes and improvements, and these changes and improvements all fall within the scope of the present invention claimed; the scope of protection claimed by the present invention is defined by the appended claims and their equivalents.
