Description

Technical Field

[0001] The present invention relates to the technical field of RTO treatment, and specifically relates to a circulating and regenerative anti-blocking RTO treatment device. Background Art

[0002] The RTO treatment device, namely the regenerative thermal oxidizer, is an efficient and environmentally friendly device for treating organic waste gas. It usually consists of a regenerator, a combustion chamber, a switching valve, etc. The regenerator is filled with heat storage materials such as ceramics. The common one is the three-chamber RTO. Its cyclic treatment process is as follows: The waste gas enters chamber A, and the heat storage body releases heat to heat the waste gas to the oxidation temperature. The purified gas is discharged through chamber B, and the heat storage body absorbs heat. At the same time, chamber C is in the backflush state; then, through the switching valve, the gas flow direction is reversed, the waste gas is redirected to chamber B, chamber A enters the cooling-backflush process, and chamber C starts to preheat. In this way, by periodically switching the gas flow path, the three regenerators alternately realize the cycle of "heat absorption - heat release - backflush";

[0003] During the operation of the RTO treatment device, the backflush operation is of great significance. The specific process is that the compressed gas enters from the top of the regenerator (i.e., the original purified gas outlet position), passes through the ceramic heat storage body along the reverse path. During this process, the compressed gas plays a cleaning role, gradually blowing the particulate matter in the pores of the heat storage body to the bottom of the regenerator (that is, the original waste gas inlet side). After that, the backflush gas carrying the particulate matter flows out from the bottom of the regenerator and then enters the subsequent treatment link;

[0004] However, there are certain limitations in the backflush process. Since the compressed gas flows inside the heat storage body, showing a trend of diffusing from a small area to a large area, this will cause the flow rate to continuously decay, thereby weakening the impact force of the gas flow. When the particulate matter accumulates seriously, the impurity particulate matter adheres closely to each other, and the backflush effect will be greatly reduced, resulting in an extended backflush time. Based on this, the present invention purposefully provides a circulating and regenerative anti-blocking RTO treatment device that can actively intervene in the serious blockage of the heat storage body to ensure the smooth progress of backflush. Summary of the Invention

[0005] The purpose of the present invention is to provide a circulating and regenerative anti-blocking RTO treatment device for the deficiencies of the prior art to solve the technical problems in the prior art.

[0006] The purpose of the present invention can be achieved by the following technical solutions:

[0007] A circulating and regenerative anti-blocking RTO treatment device, comprising:

[0008] An incinerator, in which three regenerative chambers are provided. A regenerator is provided in each regenerative chamber, and a vibration assembly is provided on each regenerative chamber. Each vibration assembly is connected to a corresponding regenerator. A combustion chamber is provided in the incinerator. The combustion chamber is located above the three regenerative chambers, and the top end of each regenerative chamber is communicated with the combustion chamber through a second conveying pipe;

[0009] A compressed gas main pipe is provided in the incinerator. The top end of each regenerative chamber is communicated with the compressed gas main pipe through a first backwashing pipe. A second discharge main pipe is provided in the incinerator. The bottom of each regenerative chamber is communicated with the second discharge main pipe through a third backwashing pipe. The compressed gas main pipe introduces compressed gas into the regenerative chamber. The compressed gas passes through the regenerator and is discharged from the second discharge main pipe through the third backwashing pipe. Each regenerative chamber is communicated with a second backwashing pipe, and the connection between the second backwashing pipe and the regenerative chamber is located above the regenerator. A turbine is rotatably installed in each second backwashing pipe. The turbine shaft penetrates through the second backwashing pipe and is connected to a rotational speed monitoring assembly. The rotational speed monitoring assembly is provided in the incinerator and is connected to the vibration assembly. After the compressed gas enters the regenerative chamber, part of the gas passes through the second backwashing pipe. At this time, the air flow drives the turbine to rotate. When the rotational speed of the turbine exceeds the threshold of the rotational speed monitoring assembly, the rotational speed monitoring assembly controls the vibration assembly to start vibrating the regenerator until the rotational speed of the turbine is lower than the threshold;

[0010] A gas flow component is provided in the incinerator. The gas flow component, the regenerative chamber and the combustion chamber are communicated with each other. The gas flow component is used to control the flow of gas in the regenerative chamber and the combustion chamber.

[0011] As a further solution of the present invention: the gas flow component includes an exhaust gas main pipe, a connecting pipe, a purified gas main pipe and a first discharge main pipe. The exhaust gas main pipe, the purified gas main pipe and the first discharge main pipe are all provided in the incinerator. Three connecting pipes are respectively communicated with the bottoms of the three regenerative chambers, and an opening and closing valve is provided at the connection between the connecting pipe and the regenerative chamber. A filter screen is provided inside the middle section of each connecting pipe. The bottom end of each connecting pipe is communicated with the exhaust gas main pipe through a first conveying pipe. The purified gas main pipe is communicated with the top end of the combustion chamber. The top end of each regenerative chamber is communicated with the purified gas main pipe through a first return pipe, and the bottom of each regenerative chamber is communicated with the connecting pipe through a second return pipe. The connection between the second return pipe and the connecting pipe is located between the filter screen and the opening and closing valve. The bottom end of each connecting pipe is communicated with the first discharge main pipe through a third return pipe. On one connecting pipe, the opening and closing valve and the first conveying pipe are opened and closed synchronously, and the third return pipe and the first conveying pipe are opened and closed asynchronously.

[0012] As a further solution of the present invention: the air outlet end of the second backflush pipe is communicated with the connecting pipe, and the connection part between the two is located between the filter screen and the opening and closing valve. When the second backflush pipe is opened, the third return pipe is opened, and the second return pipe, the opening and closing valve, and the first conveying pipe are all closed.

[0013] As a further solution of the present invention: the filter screen is fixedly connected to the inner wall of the connecting pipe. The middle part of the filter screen is made of high-temperature resistant elastic material. A connecting rod is arranged through the bottom of the connecting pipe. The connecting rod is slidably connected to the bottom of the connecting pipe. One end of the connecting rod is fixedly connected to the middle part of the filter screen. The connecting rod is driven by a driving component to move up and down. When the compressed gas sequentially passes through the second backflush pipe, the connecting pipe, the filter screen, the third return pipe and the first discharge main pipe and is discharged, the driving component drives the connecting rod to reciprocate up and down.

[0014] As a further solution of the present invention: the driving component includes a fixing plate, a cam and a transmission component. The fixing plate is fixedly installed on the inner bottom of the incinerator. A cam is arranged below each connecting rod. The cam is rotatably installed on the fixing plate. The turbine is connected to the cam through the transmission component. When the cam rotates, the cam rotates close to the connecting rod, the cam abuts against the connecting rod and makes the connecting rod rise. When the cam rotates away from the connecting rod, the connecting rod descends.

[0015] As a further solution of the present invention: the connecting rod is connected to the bottom of the connecting pipe through a spring, and the pre-tightening force of the spring pushes the connecting rod to move downward.

[0016] As a further solution of the present invention: the transmission component includes a driven wheel, a driving wheel and a synchronous belt. The driven wheel and the synchronous belt are both rotatably installed in the incinerator. The synchronous belt is drivenly connected to the driven wheel through the driving wheel. The synchronous belt is coaxially fixedly connected to the turbine, and the driven wheel is coaxially fixedly connected to the cam.

[0017] As a further solution of the present invention: the connecting pipe above the filter screen is designed in a conical shape, and the radius of the connecting pipe increases upward along its axis direction, and the radius of the connecting pipe at the place where the filter screen is installed is the smallest.

[0018] The beneficial effects of the present invention:

[0019] 1. In the present invention, the rotation speed monitoring component monitors the rotation speed of the turbine to reflect the blockage condition of the regenerator. If the rotation speed of the turbine exceeds the threshold value, it indicates that the regenerator is seriously blocked. At this time, the vibration component vibrates the regenerator to assist the impurities to break away until the compressed gas can pass through the regenerator normally. In this way, through the vibration intervention of the vibration component, it helps the impurity particles in the regenerator to break away, so that the compressed gas can pass through normally, solves the problems of difficult cleaning and long backflush time in the traditional method when facing serious blockage, enhances the ability of the system to cope with complex blockage conditions, and ensures the stable operation of the system;

[0020] 2. In the present invention, by providing a filter screen to pre-filter the waste gas entering the heat storage chamber, the problem of excessive blockage of the heat storage body is avoided from the source. Moreover, by utilizing the purified gas that needs to be discharged during the process of recycling and treating the waste gas and the clean characteristics of the purified gas itself, when the purified gas blows downward through the filter screen, the impurity particles intercepted by the filter screen during the introduction of the waste gas can be cleaned. The continuous and effective cleaning ensures that the filter screen always maintains good filtering ability throughout the waste gas treatment process;

[0021] 3. In the present invention, the second backwashing pipe is connected to the communicating pipe. Since the compressed gas flowing out of the second backwashing pipe is air that has not passed through the heat storage body and has a relatively high degree of cleanliness, it can be used to clean the filter screen, achieving the same effect as when the purified gas flows into the communicating pipe from the second return pipe to clean the filter screen, avoiding the waste of compressed gas resources flowing through the second backwashing pipe and improving the utilization rate of energy.

[0030] 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. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the scope of protection of the present invention.

[0031] Please refer to Figures 1-6 As shown, the present invention is a circulating and regenerative anti-blocking RTO treatment device, including:

[0032] An incinerator 1, in which three regenerators 2 are arranged. A regenerator body 4 is arranged in each regenerator 2, and a vibration assembly 5 is arranged on each regenerator 2. Each vibration assembly 5 is connected to a corresponding regenerator body 4. A combustion chamber 3 is arranged in the incinerator 1. The combustion chamber 3 is located above the three regenerators 2, and the top of each regenerator 2 is communicated with the combustion chamber 3 through a second conveying pipe 602;

[0033] A compressed gas main pipe 10 is arranged in the incinerator 1. The top of each regenerator 2 is communicated with the compressed gas main pipe 10 through a first backflush pipe 1001. A second discharge main pipe 11 is arranged in the incinerator 1. The bottom of each regenerator 2 is communicated with the second discharge main pipe 11 through a third backflush pipe 1003. The compressed gas main pipe 10 introduces compressed gas into the regenerator 2. The compressed gas passes through the regenerator body 4 and is discharged from the second discharge main pipe 11 through the third backflush pipe 1003. Each regenerator 2 is communicated with a second backflush pipe 1002, and the connection part of the second backflush pipe 1002 and the regenerator 2 is located above the regenerator body 4. A turbine 12 is rotatably installed in each second backflush pipe 1002. The rotating shaft of the turbine 12 penetrates through the second backflush pipe 1002 and is connected to a rotation speed monitoring assembly. The rotation speed monitoring assembly is arranged in the incinerator 1 and is connected to the vibration assembly 5. After the compressed gas enters the regenerator 2, part of the gas passes through the second backflush pipe 1002. At this time, the air flow drives the turbine 12 to rotate. When the rotation speed of the turbine 12 exceeds the threshold of the rotation speed monitoring assembly, the rotation speed monitoring assembly controls the vibration assembly 5 to start vibrating the regenerator body 4 until the rotation speed of the turbine 12 is lower than the threshold;

[0034] A gas circulation assembly is arranged in the incinerator 1. The gas circulation assembly, the regenerator 2 and the combustion chamber 3 are communicated with each other. The gas circulation assembly is used to control the circulation of gas in the regenerator 2 and the combustion chamber 3.

[0035] In a case of this embodiment, in the same flowing air path, only one of the same three channels is in a flowing state. It should be noted that the rotation speed monitoring component described in the present invention includes components such as a Hall sensor, an amplifier, a filter, and a communication module; the vibration component 5 includes components such as a motor, a pneumatic motor, and a polarization mechanism. The above components and the opening and closing valve are all prior arts, and the present invention has not improved them. Therefore, it is not necessary to disclose their specific mechanical structures and circuit structures, which does not affect the integrity of the present invention.

[0036] Working principle of the present invention: When the regenerator 2 enters the backwashing stage, the compressed gas main pipe 10 introduces compressed gas from the first backwashing pipe 1001 into the regenerator 2. The compressed gas passes through the regenerator 4 from top to bottom, thereby blowing the impurity particles accumulated in the regenerator 4 to the bottom of the regenerator 2. The air flow carries the impurities and enters the second discharge main pipe 11 through the third backwashing pipe 1003 and then is discharged. When the regenerator 4 is severely blocked by impurities, the resistance of the regenerator 4 to air flow increases. According to the principle of fluid continuity, under certain intake conditions, in order to maintain the total air flow, the air will seek a path with less resistance. Therefore, more air will flow to the second backwashing pipe 1002. At this time, the air flow will drive the turbine 12 to rotate, and the rotation speed of the turbine 12 is monitored by the rotation speed monitoring component. When the regenerator 4 is more severely blocked, more compressed gas will pour into the second backwashing pipe 1002, and the rotation speed of the turbine 12 will also increase. Thus, by monitoring the rotation speed of the turbine 12, the blockage condition of the regenerator 4 can be reflected. When the rotation speed of the turbine 12 exceeds the threshold value, it indicates that the blockage condition of the regenerator 4 is serious and intervention is required. At this time, the vibration component 5 vibrates the regenerator 4 to assist the impurity particles in the regenerator 4 to break away until the compressed gas can pass through the regenerator 4 normally. At this time, the air flow in the second backwashing pipe 1002 decreases, and the rotation speed of the turbine 12 will return below the threshold value, thereby stopping the vibration component 5 from driving the regenerator 4 to vibrate. In this way, it can be ensured that the compressed gas can quickly clean the impurities in the regenerator 4 during the backwashing stage, and through the cooperation of the vibration component 5, the situation of severe blockage of the regenerator 4 can be dealt with, and the time used in the backwashing stage can be shortened.

[0037] Such as Figures 1-6As shown, as a preferred embodiment of the present invention, the gas flow component includes an exhaust gas main pipe 6, a connecting pipe 7, a purified gas main pipe 8, and a first discharge main pipe 9. The exhaust gas main pipe 6, the purified gas main pipe 8, and the first discharge main pipe 9 are all arranged in the incinerator 1. The three connecting pipes 7 are respectively connected to the bottoms of the three regenerators 2, and an opening and closing valve is provided at the connection between the connecting pipe 7 and the regenerator 2. A filter screen 13 is arranged inside the middle section of each connecting pipe 7. The bottom end of each connecting pipe 7 is connected to the exhaust gas main pipe 6 through a first conveying pipe 601. The purified gas main pipe 8 is connected to the top end of the combustion chamber 3. The top end of each regenerator 2 is connected to the purified gas main pipe 8 through a first return pipe 801, and the bottom of each regenerator 2 is connected to the connecting pipe 7 through a second return pipe 802. The connection between the second return pipe 802 and the connecting pipe 7 is located between the filter screen 13 and the opening and closing valve. The bottom end of each connecting pipe 7 is connected to the first discharge main pipe 9 through a third return pipe 803. On one connecting pipe 7, the opening and closing valve and the first conveying pipe 601 are opened and closed synchronously, and the third return pipe 803 and the first conveying pipe 601 are opened and closed asynchronously.

[0038] In one case of this embodiment, in the same flowing gas path, only one of the same three channels is in a flowing state.

[0039] In actual application of this embodiment, the exhaust gas is first introduced from the exhaust gas main pipe 6 and enters the connecting pipe 7 through the first delivery pipe 601. At this time, the third return pipe 803 and the second return pipe 802 are both closed, and the exhaust gas enters the first heat storage chamber 2 along the connecting pipe 7. During this process, the exhaust gas will pass through the filter screen 13, thereby being filtered once, and the impurities in the exhaust gas will be intercepted under the filter screen 13. Then, the exhaust gas entering the heat storage chamber 2 passes through the high-temperature heat storage body 4 to increase the temperature of the exhaust gas. During this process, the impurities remaining in the exhaust gas will remain in the heat storage body 4. The heated exhaust gas enters the combustion chamber 3 from the second delivery pipe 602 for combustion. The purified gas after combustion will be distributed to the second heat storage chamber 2 through the purified gas main pipe 8 and the first return pipe 801. The high-temperature purified gas passes through the heat storage body 4 to transfer heat to the heat storage body 4, making the heat storage body 4 become a high-temperature state, and then the purified gas that loses heat will Enter the second return pipe 802, and the cleanliness of the purified gas is relatively high. The purified gas enters the connecting pipe 7 from the second return pipe 802. At this time, the opening and closing valve of the connecting pipe 7 is closed, and the first delivery pipe 601 is closed and the third return pipe 803 is opened, which means that the purified gas can only pass through the filter 13 from top to bottom, and enter the first discharge main pipe 9 from the third return pipe 803 for discharge. In this process, the purified gas will clean up the impurities intercepted below the filter 13, and carry the impurities to be discharged from the first discharge main pipe 9, ensuring that the filter 13 always has an efficient filtering effect, ensuring that the exhaust gas before entering the heat storage chamber 2 can be effectively filtered, and at the same time, the third combustion chamber 3 is in the back-blowing stage. After completion, the exhaust gas is introduced into the second heat storage chamber 2, and the purified gas enters the third heat storage chamber 2, and the first heat storage chamber 2 enters the back-blowing stage, so that the recycling treatment of the exhaust gas can be realized;

[0040] In this way, the exhaust gas entering the heat storage chamber 2 is pre-filtered by setting the filter 13, so as to avoid the problem of excessive blockage of the heat storage body 4 from the source, and utilize the purified gas that needs to be discharged in the process of circulating the exhaust gas and the clean characteristics of the purified gas itself. By blowing the purified gas through the filter 13 from top to bottom, the impurity particles intercepted by the filter 13 in the exhaust gas introduction stage can be cleaned, and the continuous and effective cleaning ensures that the filter 13 always maintains a good filtering ability in the entire exhaust gas treatment process.

[0041] like Figures 1-5 As shown, as a preferred embodiment of the present invention, the air outlet end of the second back-blowing pipe 1002 is connected to the connecting pipe 7, and the connecting point between the two is located between the filter screen 13 and the on-off valve, and when the second back-blowing pipe 1002 is opened, the third return pipe 803 is opened, and the second return pipe 802, the on-off valve, and the first delivery pipe 601 are all closed.

[0042] In actual application of this embodiment, when the regenerator 2 enters the backwashing stage, compressed gas flows into the regenerator 2 from the compressed gas main pipe 10 and the first backwashing pipe 1001. A part of the compressed gas flows into the second backwashing pipe 1002 and drives the turbine 12 to rotate, which is used to judge whether it is necessary to start the vibration assembly 5. At this time, the second return pipe 802, the first conveying pipe 601 and the opening and closing valve are all closed. The compressed gas flowing through the regenerator 4 carries impurity particles and flows out from the third backwashing pipe 1003 to the second discharge main pipe 11. The compressed gas flows from the second backwashing pipe 1002 to the connecting pipe 7 and blows down through the filter screen 13 from top to bottom to achieve the effect of blowing and cleaning. Then the air flow carries the impurities on the filter screen 13 and enters the first discharge main pipe 9 from the third return pipe 803. Such a design takes into account the problem of waste of resources in the compressed gas flowing out from the second backwashing pipe 1002. Therefore, the second backwashing pipe 1002 is connected to the connecting pipe 7. Since the compressed gas flowing out from the second backwashing pipe 1002 is air that has not passed through the regenerator 4 and its cleanliness is relatively high, it can be used to clean the filter screen 13, achieving the same effect as cleaning the filter screen 13 by the purified gas flowing into the connecting pipe 7 from the second return pipe 802.

[0043] As Figures 1-5 shown, as a preferred embodiment of the present invention, the filter screen 13 is fixedly connected to the inner wall of the connecting pipe 7. The middle part of the filter screen 13 is made of high-temperature resistant elastic material. A connecting rod 14 is arranged through the bottom of the connecting pipe 7. The connecting rod 14 is slidably connected to the bottom of the connecting pipe 7. One end of the connecting rod 14 is fixedly connected to the middle part of the filter screen 13. The connecting rod 14 is driven by a driving assembly to move up and down. When the compressed gas passes through the second backwashing pipe 1002, the connecting pipe 7, the filter screen 13, the third return pipe 803 and the first discharge main pipe 9 in sequence and is discharged, the driving assembly drives the connecting rod 14 to reciprocate up and down.

[0044] In actual application of this embodiment, since the middle part of the filter screen 13 is made of high-temperature resistant elastic material, when the driving assembly drives the connecting rod 14 to move up and down, it can drive the middle part of the filter screen 13 to move up and down. The fixed position of the filter screen 13 and the inner wall of the connecting pipe 7 remains unchanged, which is equivalent to the filter screen 13 vibrating. This is beneficial to vibrating and separating the impurity particles originally intercepted below the filter screen 13, so as to ensure that before the waste gas enters the regenerator 2 from the connecting pipe 7 next time, the filter screen 13 restores a good filtering effect, and fundamentally avoids the problem that too many impurity particles enter the regenerator 2 and cause the regenerator 4 to be easily blocked.

[0045] As Figures 1-5As shown, as a preferred embodiment of the present invention, the driving assembly includes a fixing plate 101, a cam 16 and a transmission assembly. The fixing plate 101 is fixedly installed on the inner bottom of the incinerator 1. A cam 16 is arranged below each connecting rod 14. The cam 16 is rotatably installed on the fixing plate 101. The turbine 12 is connected to the cam 16 through the transmission assembly. When the cam 16 rotates, the cam 16 rotates closer to the connecting rod 14, the cam 16 abuts against the connecting rod 14 and causes the connecting rod 14 to rise. When the cam 16 rotates away from the connecting rod 14, the connecting rod 14 descends.

[0046] In actual application of this embodiment, the reciprocating lifting movement of the connecting rod 14 is realized through the cooperation of the cam 16 and the connecting rod 14. When the cam 16 rotates closer to the connecting rod 14, it will abut against the connecting rod 14 and cause the connecting rod 14 to rise. At this time, the connecting rod 14 drives the middle part of the filter net 13 to rise. When the cam 16 rotates away from the connecting rod 14, the connecting rod 14 loses the support of the cam 16 and descends under the action of gravity. At this time, the connecting rod 14 drives the middle part of the filter net 13 to descend. The key is that when the rotation speed of the cam 16 is relatively fast, when the connecting rod 14 is still descending, the cam 16 abuts against the connecting rod 14 again. This impact is transmitted to the filter net 13, which can assist impurities to separate from the filter net 13 and improve the cleaning effect.

[0047] As Figures 1-5 shown, as a preferred embodiment of the present invention, the connecting rod 14 is connected to the bottom of the communicating pipe 7 through a spring 15, and the pre-tightening force of the spring 15 pushes the connecting rod 14 to move downward.

[0048] In actual application of this embodiment, the spring 15 can make the connecting rod 14 actively descend. Compared with letting the connecting rod 14 descend by gravity, when the cam 16 rotates away from the connecting rod 14, the spring 15 will immediately make the connecting rod 14 descend, with a faster speed. In this way, the vibration effect on the filter net 13 is better and the cleaning effect is also better.

[0049] As Figures 1-6 shown, as a preferred embodiment of the present invention, the transmission assembly includes a driven wheel 17, a driving wheel 18 and a synchronous belt 19. The driven wheel 17 and the synchronous belt 19 are both rotatably installed inside the incinerator 1. The synchronous belt 19 is drivingly connected to the driven wheel 17 through the driving wheel 18. The synchronous belt 19 is coaxially and fixedly connected to the turbine 12, and the driven wheel 17 is coaxially and fixedly connected to the cam 16.

[0050] In practical application of this embodiment, when compressed gas enters the second backwashing pipe 1002 to drive the turbine 12 to rotate, the turbine 12 drives the synchronous belt 19 to rotate synchronously. The synchronous belt 19 drives the driven wheel 17 to rotate synchronously through the driving wheel 18. The driven wheel 17 causes the cam 16 to rotate, and the cam 16 causes the connecting rod 14 to reciprocate up and down, thereby driving the filter screen 13 to vibrate. At the same time, after the compressed gas enters the second backwashing pipe 1002, it will also pass through the filter screen 13, so as to combine air flow cleaning and vibration cleaning, and improve the cleaning effect on the filter screen 13.

[0051] As Figures 1-5 shown, as a preferred embodiment of the present invention, the communicating pipe 7 above the filter screen 13 is designed in a conical shape, and the radius of the communicating pipe 7 increases upward along its axis direction, and the radius of the communicating pipe 7 at the installation position of the filter screen 13 is the smallest.

[0052] In practical application of this embodiment, the filter screen 13 is installed at the position with the smallest radius on the communicating pipe 7. When the air flow from the second return pipe 802 and the second backwashing pipe 1002 flows through the communicating pipe 7 and passes through the filter screen 13, since the radius of the communicating pipe 7 gradually becomes smaller, the flow rate of the air flow will increase. In this way, a stronger air flow can blow through the filter screen 13, thereby improving the cleaning effect on the impurities intercepted below the filter screen 13.

[0053] The above has described a specific embodiment of the present invention in detail, but the above content is only a preferred embodiment of the present invention and cannot be considered as limiting the scope of implementation of the present invention. All equivalent changes and improvements made according to the scope of the application of the present invention should still fall within the scope covered by the patent of the present invention.
