Description

TECHNICAL FIELD

[0001] The present application relates to a dust collector, in particular to a multi-tube dust collector with vibration cleaning. BACKGROUND

[0002] A plurality of cyclone separators are installed in the multi-tube dust collector, and dust is separated and discharged after the cyclone separators guide the centrifugal flow of the dust-containing air. In actual production and use, dust is prone to accumulate on the windward surface of the air guide pipe of the cyclone separator and the cyclonic blades of the guide impeller. After a long period of operation, the accumulated dust will affect the smoothness of the air flow channel between the cyclonic blades and the guiding effect of the air flow, thus reducing the processing air volume and dust removal effect of the dust collector. Since the multi-tube dust collector is usually applied to the tail gas treatment in the metallurgical industry, shutdown for maintenance will affect the work of the entire production line. Therefore, it is desirable to delay the accumulation of dust and prolong the period of shutdown for dust removal as much as possible without stopping the machine.

[0003] A kind of automatic high efficiency anti-blocking compound layered dust collector disclosed in Chinese patent with publication number CN104826748A is provided with a supporting plate air jet nozzle and an impeller air jet nozzle that can spray high pressure gas inside the dust collector, which can slow down the adhesion of sticky dust on the supporting plate and the guide impeller, and reduce the frequency of manual dust cleaning. However, this scheme also has some shortcomings. Mainly, these set air jet nozzles need to be set at a position close to the guide impeller, so that the high pressure jet can directly act on the blades. However, the closer to the guide impeller, the greater the influence of the air jet nozzle and the corresponding pipeline on the air flow entering the guide impeller, which will also affect the dust removal efficiency. SUMMARY

[0004] In view of the above-mentioned defects of the prior art, the task of the present application is to provide a multi-tube dust collector with vibration cleaning, which solves the problem of daily dust accumulation and cleaning of the air guide pipe and the guide impeller in the multi-tube dust collector, and slows down the accumulation of dust.

[0005] The technical scheme of the present application is as follows: a multi-tube dust collector with vibration cleaning, comprising a dust removal cavity provided with an air inlet and an air outlet, a dust hopper communicated with the bottom of the dust removal cavity, a cyclone separator provided in the dust removal cavity, an air guide pipe provided in the cyclone separator, a swing knocking rod and a rotating shaft provided in the dust removal cavity at the side of the air guide pipe, the swing knocking rod being suspended on a support rod, the support rod being fixed to the wall of the dust collector, a tab being provided on the rotating shaft, the tab being used to swing and knock the swing knocking rod after the swing knocking rod is deviated from the natural downward position.

[0006] Further, the cyclone separators are arranged in a matrix, the swing knock rods extend in the row arrangement direction of the cyclone separators, and multiple swing knock rods are arranged in parallel in the column arrangement direction of the cyclone separators, and the multiple swing knock rods arranged in parallel are connected by a synchronous connecting rod, and the synchronous connecting rod makes the multiple swing knock rods swing together. The multiple swing knock rods are connected by the synchronous connecting rod, the number of the wobble shafts and the wobble pieces can be reduced, the structure is simplified, and the internal space of the dust removal cavity is occupied.

[0007] Further, the synchronous connecting rod is rotatably connected with the swing knock rod and has a gap.

[0008] Further, the cyclone separators are arranged in a matrix, the swing knock rods extend in the row arrangement direction of the cyclone separators and are provided with multiple segments, the wobble pieces are provided with multiple pieces and correspond to the segments of each swing knock rod, and the wobble pieces are arranged at multiple positions in the circumferential direction of the wobble shaft. The wobble pieces at different positions in the circumferential direction are used to drive the segments of the swing knock rods at different times, so that the gas guide pipes of the cyclone separators are knocked to remove dust in groups at different times, resonance caused by the vibration of all the gas guide pipes of the cyclone separators at the same time is avoided, the connecting structure is damaged, and only one driving device is needed to realize dust removal at different times and in different groups.

[0009] Further, the multiple segments of the swing knock rod formed in the row arrangement direction of the cyclone separators are suspended on the same support rod, the number of the support rods is reduced, and the influence on the airflow in the dust remover is reduced.

[0010] Further, one end of the wobble shaft extends to the outside of the dust remover, and the outside of the dust remover is provided with a driving device for driving the wobble shaft to rotate. The external driving device is convenient to maintain and has a long service life and is not affected by the dust-containing airflow.

[0011] Compared with the prior art, the application has the following advantages:

[0012] The swing knock rod and the wobble shaft can be arranged away from the guide impeller, the vibration of the gas guide pipe is conducted to the guide impeller to produce a dust removal effect, the influence of the additional swing knock rod and the wobble shaft on the airflow at the inlet of the cyclone separator is reduced, the dust removal efficiency of the cyclone separator is maintained, the vibration of the gas guide pipe can also clean the dust accumulated on the wall of the gas guide pipe, the continuous working time of the multi-tube dust remover is prolonged as a whole, the function component for knocking vibration has a simple structure, the driving device is external and is convenient to maintain and reform, the reform cost of the original multi-tube dust remover is low, and the reform is easy to implement.

[0019] The present invention will be further described below with reference to embodiments. It should be understood that these embodiments are only for illustrating the present invention and are not intended to limit the scope of the present invention. After reading this description, any modifications of this description in various equivalent forms by those skilled in the art will fall within the scope defined by the appended claims.

[0020] Please combine Figures 1 to 4 As shown in the figure, the multi-tube dust collector with vibration cleaning involved in this embodiment includes a dust collector body, which has a dust collection chamber 1 and a dust hopper 2. The dust hopper 2 is connected to the bottom of the dust collection chamber 1 and is used to collect the dust discharged from the dust collection chamber 1. The opposite sides of the dust collection chamber 1 are respectively set as an air inlet 3 and an air outlet 4. A partition plate 5 is provided in the dust collection chamber 1, which divides the dust collection chamber 1 into two parts, namely an air inlet chamber 1a and an air outlet chamber 1b. The air inlet chamber 1a is connected to the air inlet 3 and is arranged close to the dust hopper 2, while the air outlet chamber 1b is connected to the air outlet 4. Generally, the partition plate 5 is inclined, with the side closer to the air inlet 3 being higher and the side closer to the air outlet 4 being lower. A support plate 6 is provided on the bottom surface of the air inlet chamber 1a, which is also the bottom surface of the dust collection chamber 1. The support plate 6 is used to install a cyclone separator.

[0021] The cyclone separators in the multi-tube dust collector are arranged in a matrix. The cyclone separator mainly comprises three parts, i.e. a cyclone cylinder 7, a guide vane and a gas guide pipe 8. The top of the cyclone cylinder 7 is open and is mounted on a support plate 6. The cylinder body of the cyclone cylinder 7 extends downward from the support plate 6. The cylinder body of the cyclone cylinder 7 is connected to the ash hopper 2 of the air inlet chamber 1a. The guide vane is mounted on the top of the cyclone cylinder 7. The lower end of the gas guide pipe 8 penetrates the guide vane and enters the cylinder body of the cyclone cylinder 7. The upper end of the gas guide pipe 8 penetrates the partition plate 5 and enters the air outlet chamber 1b. After the dust-containing air flow enters the air inlet chamber 1a from the air inlet 3, it is guided by the guide vane and rotates. The dust is separated by centrifugal force and falls into the ash hopper 2 from the cylinder body of the cyclone cylinder 7. The relatively clean air flow flows upward from the gas guide pipe 8 into the air outlet chamber 1b and is discharged from the air outlet 4. It can be understood that, in order not to affect the air outlet, the part of the gas guide pipe 8 in the air outlet chamber 1b should not be too long, that is, the part exposed from the upper part of the partition plate 5 is relatively short. Therefore, in the present embodiment, the functional part that generates vibration is arranged in the air inlet chamber 1a, which is easier to arrange.

[0022] The functional part that generates vibration mainly comprises a swing and knock rod 9 and a rotating shaft 10. The corresponding driving device 16 is arranged outside the dust removal chamber 1. In order to facilitate the arrangement of the swing and knock rod 9, a support rod 11 is arranged in the air inlet chamber 1a. The support rod 11 extends in the row arrangement direction of the cyclone separators. In the present embodiment, the row arrangement direction of the cyclone separators is the direction perpendicular to the line connecting the air inlet 3 and the air outlet 4. The column arrangement direction is the direction of the line connecting the air inlet 3 and the air outlet 4. The support rod 11 is a fixed rod for suspending the swing and knock rod 9. The two ends of the support rod 11 are fixed on the opposite wall surfaces of the dust collector body. When the span of the support rod 11 is large, a plurality of support columns 12 can be arranged on the support plate 6 to support the support rod 11. The support rod 11 is located on the side of the gas guide pipe 8 of the cyclone separator in each row. The swing and knock rod 9 also extends in the row arrangement direction of the cyclone separators. In the row arrangement direction of the cyclone separators, the swing and knock rod 9 has a plurality of segments. The two ends of each segment of the swing and knock rod 9 are suspended on the support rod 11 by a hanger rod 13. The top end of the hanger rod 13 is rotatably connected to the support rod 11 and cannot move axially. The bottom end of the hanger rod 13 is fixedly connected to the swing and knock rod 9. The swing and knock rod 9 is also located on the side of the gas guide pipe 8 in the natural downward position. When the swing and knock rod 9 is lifted away from the gas guide pipe 8 and released, the swing and knock rod 9 swings towards the gas guide pipe 8 and knocks the gas guide pipe 8, causing the gas guide pipe 8 to vibrate and the guide vane to vibrate, thereby achieving the purpose of dust removal. As a preferred specific embodiment, a protruding short column 14 can be arranged on the swing and knock rod 9 at a position corresponding to the gas guide pipe 8 as a knocking point to knock the gas guide pipe 8.

[0023] The swing of the swing knock rod 9 is driven by the poking shaft 10. It can be understood that each swing knock rod 9 needs to swing, and if a corresponding poking shaft 10 is arranged for each swing knock rod 9, the whole mechanism will become complex, so if the multiple swing knock rods 9 arranged in the column direction of the cyclone separator can be formed into a group driven by one poking shaft 10, the mechanism can be simplified. Specifically, the multiple swing knock rods 9 arranged in the column direction of the cyclone separator are connected by one synchronous connecting rod 15, the synchronous connecting rod 15 is rotationally connected with each swing knock rod 9 arranged in the column direction, so that when one swing knock rod 9 swings, it will synchronously drive other swing knock rods 9 arranged in the column direction to swing. In actual application, the connection between the synchronous connecting rod 15 and the swing knock rod 9 maintains a certain gap, so that the problem that the swing knock rod 9 cannot knock in place due to the size error of different swing knock rods 9 and the air guide pipe 8 can be avoided.

[0024] The poking shaft 10 is arranged below the swing knock rod 9 and parallel to the swing knock rod 9. The multiple supports 12 on the supporting plate 6 can simultaneously act as the bearing seat of the poking shaft 10, a bearing is installed to form a rotational connection with the poking shaft 10, one end of the poking shaft 10 extends from the wall surface of the dust collector body for connection with the driving device 16. A plurality of radial poking pieces 17 are welded on the poking shaft 10, when the poking shaft 10 is rotated, the poking pieces 17 are used to poke the swing knock rod 9 to make the swing knock rod 9 deviate from the natural drooping position (as shown in Figure 5 、 6 It can be understood that when the swing knock rod 9 is arranged with multiple segments in the row arrangement direction of the cyclone separator, in order to be able to poke each segment of the swing knock rod 9, the poking pieces 17 are also correspondingly arranged. Each poking piece 17 corresponds to one segment of the swing knock rod 9. In order to make the swing knock rod 9 with different segments swing and knock the air guide pipe 8 at different times, these poking pieces 17 are arranged at multiple positions in the circumferential direction of the poking shaft 10, and in the embodiment, each poking piece 17 is arranged at an interval of 90° in the circumferential direction. The segments of the swing knock rod 9 are poked at different times by the poking pieces 17 at different positions in the circumferential direction, so that the air guide pipes 8 of the cyclone separators are knocked to remove dust in groups at different times, avoiding the resonance caused by the vibration of all air guide pipes 8 of the cyclone separators at the same time, damaging the connecting structure, and only one driving device 16 is needed to realize the dust removal at different times and in groups.

[0025] The driving device 16 is a reduction motor, an installation platform 18 is welded on the outer wall of the dust collector body, the reduction motor is installed on the installation platform 18, and the rotating shaft of the reduction motor is connected with one end of the poking rotating shaft 10 through a shaft coupling 19. The working process of the above embodiment is that the reduction motor drives the poking rotating shaft 10 to rotate, so that the poking piece 17 further pokes the swinging and knocking rod 9, and after the swinging and knocking rod 9 deviates from the natural drooping position and is separated from the poking piece 17, the swinging and knocking rod 9 falls and swings and knocks the air guide pipe 8 under the action of gravity, so that the dust removal purpose is achieved.
