[0003] The existing bag dust collector cannot efficiently process and collect the filtered material. It simply uses low-pressure pulses to blow the filtered material off the filter bag. The filtered material treatment effect is single. At the same time, during the pulse backblowing process, the blown-off filtered material will raise dust in the dust collector, which will not only be contaminated on the inner wall of the dust collector, but also take a long time to fall into the ash hopper, resulting in low treatment efficiency. Summary of the Invention

[0004] The purpose of the present invention is to solve the problems of single filter processing effect and low processing efficiency. The present invention provides a filter processor for flue gas purification.

[0005] In order to achieve the above-mentioned purpose, the present invention specifically adopts the following technical solutions:

The bracket is sleeved on the adjusting screw, and a nut sleeve is provided on the top of the bracket. A hexagonal nut is inserted into the inside of the nut sleeve, and the hexagonal nut is threadedly connected to the adjusting screw. A buffer spring is provided between the bracket and the connecting plate.

[0012] Furthermore, two groups of adjusting screws are provided, and the two groups of adjusting screws are designed to be diagonal.

[0013] Furthermore, a transmission groove is provided at the bottom of the connecting plate, and a rotating wheel, a driven wheel and a driving wheel are rotatably installed inside the transmission groove.

DETAILED DESCRIPTION

[0031] To make the objectives, technical solutions and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention.

[0032] like Figures 1-10 As shown, a filter processor for flue gas purification includes a bottom plate 23 fixedly mounted on the bottom of a bag filter. The bottom plate 23 is provided with drainage holes 24 corresponding to the distribution of the bags. A telescopic sleeve 8 is mounted on the top of each drainage hole 24. The inner diameter of the telescopic sleeve 8 is larger than the outer diameter of the bags. The top of the telescopic sleeve 8 is fixedly connected to a lifting plate 4 that can automatically rise and fall.

[0033] The lifting plate 4 has a linear hole inside that is connected to the telescopic sleeve 8. A sealing sleeve 9 is provided inside the hole. The sealing sleeve 9 is hollow inside. The bottom of the lifting plate 4 is provided with an adjustment mechanism that can adjust the air pressure inside the sealing sleeve 9.

[0034] When dust collection is needed, the lifting plate 4 is controlled to rise, and the lifting plate 4 drives all the telescopic sleeves 8 to be respectively put on the cloth bag. At this time, the air pressure inside the sealing sleeve 9 is small, and the sealing sleeve 9 will not contact the cloth bag. Then, during pulse backblowing, the dust directly enters the ash hopper through the telescopic sleeve 8 without splashing in the dust collector. After the pulse dust collection is completed, the lifting plate 4 is controlled to fall, and the lifting plate 4 drives the telescopic sleeve 8 to be compressed, and the telescopic sleeve 8 quickly guides the suspended dust into the ash hopper, thereby without waiting for the dust to settle, and the processing efficiency is high. When the telescopic sleeve 8 is completely away from the cloth bag, the air pressure inside the sealing sleeve 9 is increased through the adjusting mechanism, and the sealing sleeve 9 expands to block the top opening of the telescopic sleeve 8. At this time, the lifting plate 4 is continued to be controlled to fall quickly, and the gas inside the telescopic sleeve 8 is quickly pressed out, generating an airflow to carry the dust inside the telescopic sleeve 8 out, thereby efficiently completing the filtered material processing and ensuring that dust will not accumulate inside the telescopic sleeve 8. At the same time, through this design, there is no need to set a valve at the bottom of the ash hopper. The lifting plate 4 and the sealing sleeve 9 can prevent the ash hopper from deflating, and the structure is compact.

[0035] While controlling the lifting plate 4 to descend, the air pressure inside the sealing sleeve 9 is increased through the adjusting mechanism. At this time, the sealing sleeve 9 is not sealed, and the sealing sleeve 9 clamps the cloth bag. The lifting plate 4 descends and drives the sealing sleeve 9 to descend. The sealing sleeve 9 scrapes off the dust on the surface of the cloth bag, completing the secondary cleaning with high cleaning quality. At the same time, it can prevent the dust floating inside the telescopic sleeve 8 from overflowing when it is compressed, and the treatment effect is good.

[0036] like Figure 6 As shown, in some embodiments, the sealing sleeve 9 is designed to be inverted cone-shaped. Through this design, when the sealing sleeve 9 rises, it will not clamp the cloth bag and can guide the dust. When the sealing sleeve 9 descends or seals, the clamping and sealing effects are better.

[0037] like Figure 2 As shown, in some embodiments, the bottom of the lifting plate 4 is linearly fixedly connected to a piston rod 11 corresponding to the sealing sleeve 9, and the bottom sealing sleeve of the piston rod 11 is connected to a cylinder 12.

[0038] When the telescopic sleeve 8 is completely away from the cloth bag, the cylinder 12 is pressed against the bottom plate 23, and then the lifting plate 4 is controlled to drop rapidly. The lifting plate 4 drives the piston rod 11 to drop rapidly relative to the cylinder 12, and the gas in the cylinder 12 is quickly pressed into the sealing sleeve 9. The sealing sleeve 9 expands to block the top opening of the telescopic sleeve 8. At the same time, the lifting plate 4 quickly presses out the gas inside the telescopic sleeve 8, generating an airflow to bring out the dust inside the telescopic sleeve 8, thereby efficiently completing the filtered material processing and ensuring that dust does not accumulate inside the telescopic sleeve 8.

[0039] like Figure 2-Figure 4 As shown, in some embodiments, a connecting plate 10 is fixedly connected to the bottom of the cylinder 12, and the connecting plate 10 connects all the cylinders 12 together. A through hole 22 is opened inside the connecting plate 10, and the telescopic sleeve 8 can pass through the through hole 22. Through the setting of the connecting plate 10, it is only necessary to control the movement of the connecting plate 10 relative to the lifting plate 4 to control the internal air pressure of the sealing sleeve 9, and to ensure that the force is more stable when the piston rod 11 is pressed down.

[0040] like Figure 8 As shown, in some embodiments, an automatically rotating adjusting screw 13 is installed on the top of the connecting plate 10, and a bracket 14 is fixedly connected to the bottom of the lifting plate 4. The bracket 14 is sleeved on the adjusting screw 13. A nut sleeve 15 is provided on the top of the bracket 14. A hexagonal nut 16 is inserted into the inside of the nut sleeve 15. The hexagonal nut 16 is threadedly connected to the adjusting screw 13, and a buffer spring 17 is provided between the bracket 14 and the connecting plate 10.

[0041] By controlling the adjustment screw 13 to rotate, the hexagonal nut 16 cannot rotate in the nut sleeve 15. The bracket 14, under the action of the buffer spring 17, stably clamps the hexagonal nut 16 in the nut sleeve 15. Under the action of the adjustment screw 13, the hexagonal nut 16 controls the distance between the connecting plate 10 and the lifting plate 4 through the bracket 14. When the lifting plate 4 is controlled to descend, the adjustment screw 13 is controlled to rotate, and the adjustment screw 13 reduces the distance between the connecting plate 10 and the lifting plate 4. The piston rod 11 descends relative to the cylinder 12. At this time, the internal air pressure of the sealing sleeve 9 increases. At this time, the sealing sleeve 9 is not sealed. The sealing sleeve 9 clamps the cloth bag, and the lifting plate 4 descends, driving the sealing sleeve 9. Descends, the sealing sleeve 9 scrapes off the dust on the surface of the bag, completing the secondary cleaning. When the connecting plate 10 descends to the position of the bottom plate 23, the lifting plate 4 is controlled to descend quickly. The lifting plate 4 drives the piston rod 11 to descend quickly relative to the cylinder 12, and the gas in the cylinder 12 is quickly pressed into the sealing sleeve 9. The sealing sleeve 9 expands to block the top opening of the telescopic sleeve 8. At the same time, the lifting plate 4 quickly presses out the gas inside the telescopic sleeve 8, generating an airflow to bring out the dust inside the telescopic sleeve 8. At the same time, the lifting plate 4 drives the bracket 14 to descend relative to the adjusting screw 13, and the bracket 14 compresses the buffer spring 17. The bracket 14 drives the nut sleeve 15 to descend relative to the hexagonal nut 16 without affecting the normal compression of the cylinder 12.

[0042] like Figure 3 As shown, in some embodiments, two groups of adjusting screws 13 are provided, and the two groups of adjusting screws 13 are designed to be diagonal. Through this design, the force on the connecting plate 10 is stabilized.

[0043] like Figure 9 As shown, in some embodiments, a transmission groove 18 is opened at the bottom of the connecting plate 10, and a rotating wheel 19, a driven wheel 20 and a driving wheel 21 are rotatably installed inside the transmission groove 18. The rotating wheel 19 is fixedly connected to the adjusting screw 13, the rotating wheel 19 is meshed with the driven wheel 20, and the driven wheel 20 is meshed with the driving wheel 21. An adjusting motor is installed on the top of the connecting plate 10, and the driving wheel 21 is transmission-connected to the output end of the adjusting motor.

[0044] The arrangement of the transmission groove 18 does not affect the connection plate 10 being placed on the bottom plate 23. The driving wheel 21 is driven to rotate by the adjusting motor, the driving wheel 21 drives the driven wheel 20 to rotate, the driven wheel 20 drives the rotating wheel 19 to rotate, and the rotating wheel 19 drives the adjusting screw 13 to rotate, so that the control is stable and the structure is compact.

[0045] like Figure 2 、 Figure 7 As shown, in some embodiments, a rotating shaft 1 driven by a motor is rotatably installed on the top of the base plate 23, a spiral groove 2 is provided on the outside of the rotating shaft 1, the spacing of the lower half of the spiral groove 2 is larger than that of the upper half, an axial hole 5 that can pass through the rotating shaft 1 is provided inside the lifting plate 4, and a spiral clamp 6 is provided on the inner wall of the axial hole 5, which is clamped in the spiral groove 2, and an axial hole 5 that can pass through the rotating shaft 1 is also provided inside the connecting plate 10.

[0046] The motor drives the shaft 1 to rotate, and the shaft 1 drives the lifting plate 4 to rise and fall through the spiral groove 2 and the spiral block 6, and the control is stable. At the same time, since the spacing of the lower half of the spiral groove 2 is larger than that of the upper half, the lifting plate 4 will drop quickly when it is away from the cloth bag, and the control is convenient.

[0047] like Figure 2 As shown, in some embodiments, three groups of guide columns 3 are provided on the top of the base plate 23, and the three groups of guide columns 3 and the rotating shaft 1 are respectively arranged at the four corners of the base plate 23, and the lifting plate 4, the connecting plate 10, the adjusting screw 13 and the rotating wheel 19 are provided with guide holes 7 that can pass through the guide columns 3.

[0048] The three sets of guide posts 3 and the rotating shaft 1 are respectively arranged at the four corners of the bottom plate 23 to improve the lifting stability of the lifting plate 4.

[0049] like Figure 5 As shown, in some embodiments, the telescopic sleeve 8 is composed of a corrugated telescopic tube 81 and an elastic telescopic tube 82 . The corrugated telescopic tube 81 and the elastic telescopic tube 82 are cross-arranged, and the elastic telescopic tube 82 is a rubber sleeve.

[0050] With this design, the telescopic sleeve 8 has a longer deformation length and a compact structure, and when the telescopic sleeve 8 is pressed downward, a larger airflow is generated.

[0051] The above description of the disclosed embodiments is intended to enable one skilled in the art to implement or use the present invention. Various modifications to these embodiments will be readily apparent to one skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention is not limited to the embodiments shown herein but is intended to conform to the widest scope consistent with the principles and novel features disclosed herein.
