Description

Technical Field

[0001] This invention belongs to the field of desulfurization filter technology and relates to a replacement desulfurization filter for desulfurization equipment. Background Technology

[0002] Desulfurization filters are key equipment used in flue gas desulfurization in coal-fired power plants. They primarily reduce sulfur dioxide emissions by adsorbing impurity particles in the flue gas onto the filter surface. Therefore, desulfurization filters play a crucial role in reducing air pollutant emissions, especially sulfur dioxide emissions.

[0003] In existing published literature, patent publication number CN216295731U discloses a desulfurization filter screen for a desulfurization device. This filter screen has multiple compression springs fixedly connected to the inner wall of the side of the telescopic groove away from the movable groove, and one end of each compression spring is fixedly connected to a movable rod. A compression plate is fixedly connected to the side of the movable rod closest to the movable groove. This invention has the advantage of facilitating the replacement of the desulfurization filter screen; however, this desulfurization filter screen has the following drawbacks.

[0004] When desulfurization filters are used in desulfurization equipment, although they can filter out impurities, these impurities can clog the filter screen during the filtration process, affecting normal desulfurization filtration. This requires disassembling the entire equipment and replacing the filter screen, which is time-consuming and labor-intensive. Therefore, a replaceable desulfurization filter screen for desulfurization equipment is provided. Summary of the Invention

[0005] The purpose of this invention is to overcome the shortcomings of the prior art and provide a replaceable desulfurization filter for desulfurization equipment, which is easy to disassemble and replace.

[0006] To achieve the above objectives, the present invention discloses a replaceable desulfurization filter screen for desulfurization equipment, comprising a support ring, an electric cylinder, and a push block. The electric cylinder is fixed on the inner wall of the support ring, the push block is fixed on the output end of the electric cylinder, and a linkage replacement mechanism is installed on the top of the push block.

[0007] The linkage replacement mechanism includes an angle sensor set at the top of the push block, the output end of the angle sensor is fixedly connected to a linkage shaft, and a toothed ring is fixedly installed on the outer wall of the linkage shaft;

[0008] A fixing plate is welded to the end of the linkage shaft, and a replacement ring and a replacement filter are arranged sequentially from bottom to top above the fixing plate. The replacement filter and the fixing plate are both fixedly connected to the replacement ring.

[0009] Below the fixed plate, from top to bottom, there is a connecting ring and a main filter screen, and both the main filter screen and the fixed plate are fixedly connected to the connecting ring;

[0010] A separation displacement assembly is embedded inside the support ring and located on one side of the electric cylinder; a disengagement assembly is provided on the side of the linkage shaft.

[0011] Furthermore, the angle sensor is fixedly connected to the push block, and the bottom cross-section of the push block is a rectangular structure.

[0012] Furthermore, the replacement ring and the connecting ring are symmetrically arranged about the fixed disk, and the cross-section of the replacement ring and the connecting ring is a circular ring structure;

[0013] The outer wall of the main filter screen is slidably connected to the inner wall of the support ring.

[0014] Furthermore, a controller is mounted on the side of the angle sensor;

[0015] The bottom end of the support ring is connected to a branch ring, and the bottom end of the branch ring is welded to a bottom ring. The cross-sections of both the bottom ring and the support ring are circular ring structures.

[0016] Furthermore, a support block is welded to the side of the push block, and a sliding frame is fixedly connected to one side of the support block.

[0017] The inner wall of the slide frame is rotatably connected to a transmission screw, and a reduction motor for driving the transmission screw to rotate is fixedly installed on the side of the slide frame. A sleeve block is threadedly connected to the outer wall of the transmission screw, and the outer wall of the sleeve block is slidably connected to the slide frame.

[0018] An L-shaped toothed rack is welded to the top of the sleeve block, and the L-shaped toothed rack is slidably connected to the outer wall of the toothed ring.

[0019] Furthermore, the separation displacement assembly includes a rotary motor embedded and fixedly installed inside the support ring and located on the side of the electric cylinder;

[0020] The output end of the rotary motor is coaxially connected to a rotating shaft, the top of the rotating shaft is welded to a rotating frame, a drive motor is fixedly installed on the bottom of the inner wall of the rotating frame, and the output end of the drive motor is coaxially connected to a linkage screw.

[0021] The outer wall of the linkage screw is threaded with two sleeve sliders, and each sleeve slider has an extrusion plate welded to its side.

[0022] Furthermore, both of the aforementioned connecting sliders are slidably connected to the rotating frame.

[0023] Furthermore, the two threads on the outer wall of the linkage screw are opposite and symmetrically arranged, and the two extrusion plates are symmetrically arranged about the middle of the linkage screw.

[0024] Furthermore, the disengagement component includes a positioning arc-shaped strip disposed on the side of the linkage shaft, and the positioning arc-shaped strip is fixedly connected to the fixed plate;

[0025] The replacement ring and the connecting ring are slidably connected to the inner wall of the positioning arc strip. A sliding support frame is welded to the outer wall of the positioning arc strip. A separation screw is rotatably connected inside the sliding support frame. A stepper motor for driving the separation screw to rotate is fixedly installed on the inner wall of the sliding support frame.

[0026] The outer wall of the separating screw is threadedly connected to a threaded sleeve block, and two inserts are fixedly installed on the side of the threaded sleeve block. The two inserts are arranged at equal intervals from top to bottom.

[0027] The positioning arc strip and the fixing plate are both slidably connected to the insert.

[0028] Furthermore, both inserts are slidably connected to the sliding support frame, and one side of each insert is rounded.

[0029] The present invention has the following beneficial effects:

[0030] In specific operation, when the angle value sensed by the angle sensor is the same as the angle value set by the controller, the controller shuts off the reduction motor, and the electric cylinder drives the push block to move down. The fixed plate drives the connecting ring to move the main filter screen down and insert it into the support ring, thus completing the replacement operation of the replacement filter screen. This automatically and quickly replaces the filter screen, making the disassembly and replacement of the filter screen more time-saving and labor-saving.

[0031] Furthermore, a separation displacement assembly is adopted. A drive motor drives a linkage screw to rotate, and the linkage screw carries two sleeve sliders that move away from each other under the action of threaded transmission force. The two sleeve sliders each carry two extrusion plates away from each other. A rotary motor drives a rotating shaft to rotate 90 degrees, and the two sleeve sliders each carry two extrusion plates to rotate and separate. This allows for easy unlocking and automatic replacement of the main filter, making filter replacement more time-saving and labor-saving.

[0032] Furthermore, a detachment component is adopted, with a stepper motor driving the separation screw. The separation screw drives the threaded sleeve block to move under the action of thread transmission force. The threaded sleeve block drives the two inserts to move. The two inserts move to the left and are no longer connected to the positioning arc strip. In this way, the positioning arc strip and the fixed plate are separated, and the replacement filter can be quickly removed. This makes it convenient to directly remove the damaged replacement filter in the future, and the replacement is more time-saving and labor-saving.

[0033] Furthermore, the two connecting sliders carry the two extrusion plates and rotate to separate. Next, the main filter screen is inserted into the support ring to complete the replacement of the replacement filter screen. Finally, the replacement filter screen can be unlocked and removed. In summary, personnel do not need to disassemble the entire equipment to replace the new filter screen. The replacement filter screen can be replaced automatically, making the replacement of the filter screen more time-saving and labor-saving. Attached Figure Description

[0057] As one embodiment of the present invention, see attached... Figures 1-4 As shown, the separation displacement assembly includes a rotary motor 21 embedded and fixedly installed inside the support ring 1 and located on one side of the electric cylinder; the output end of the rotary motor 21 is connected to a rotating shaft 22, and a rotating frame 23 is welded to the top of the rotating shaft 22. A drive motor 24 is fixedly installed at the bottom of the inner wall of the rotating frame 23, and the output end of the drive motor 24 is coaxially connected to a linkage screw 25; the outer wall of the linkage screw 25 is threadedly connected to two sleeve sliders 26, and each sleeve slider 26 has a pressing plate 27 welded to its side.

The two threads on the outer wall of the linkage screw 25 are opposite and symmetrically arranged, and the two pressing plates 27 are symmetrically arranged about the middle of the linkage screw 25.

[0058] As one embodiment of the present invention, see attached... Figures 5-7 As shown, the disengagement assembly includes a positioning arc-shaped strip 28 disposed on the side of the linkage shaft 5, and the positioning arc-shaped strip 28 is fixedly connected to the fixed plate 7; the replacement ring 8 and the connecting ring 10 are both slidably connected to the inner wall of the positioning arc-shaped strip 28; a sliding support frame 29 is welded to the side of the outer wall of the positioning arc-shaped strip 28; a separation screw 30 is rotatably connected inside the sliding support frame 29; a stepper motor 31 for driving the separation screw 30 to rotate is fixedly installed on the inner wall of the sliding support frame 29; a threaded sleeve block 32 is threadedly connected to the outer wall of the separation screw 30; and several inserts 33 are fixedly installed on the side of the threaded sleeve block 32, with each insert 33 arranged equidistantly from top to bottom.

[0059] The positioning arc strip 28 and the fixing plate 7 are slidably connected to the insert strip 33, and the insert strip 33 is slidably connected to the sliding support frame 29. The sides of the insert strip 33 are rounded.

[0060] The working principle of this invention is as follows:

[0061] Step 1: During installation, place the bottom ring 14 in the desulfurization equipment, and ensure that the outer walls of the bottom ring 14, the support ring 13, and the support ring 1 are all attached to the inner wall of the desulfurization equipment. The support ring 1, the support ring 13, and the bottom ring 14 are all fixed to the inner wall of the support ring 1. The flue gas generated by the desulfurization equipment enters the bottom ring 14, is desulfurized and filtered through the main filter screen 11, and then discharged upwards through the side hole of the connecting ring 10.

[0062] Step two, during disengagement, the drive motor 24 drives the linkage screw 25 to rotate. The linkage screw 25, carrying two connecting sliders 26, moves them away from each other under the force of the threaded transmission. One connecting slider 26 moves upward, and the other moves downward. The two connecting sliders 26, each carrying one of the two pressing plates 27, move away from each other. The top pressing plate 27 no longer presses against the replacement ring 8, and the bottom pressing plate 27 no longer presses against the connecting ring 10. The two connecting sliders 26 move downward along the inner wall of the rotating frame 23, and the rotation motor 21 drives the rotating shaft 22 to rotate 90 degrees. The rotating shaft 22 rotates the rotating frame 23, which in turn drives the linkage screw 25, causing the two connecting sliders 26 to rotate. The two connecting sliders 26, each carrying one of the two pressing plates 27, rotate and separate.

[0063] Step 3, during replacement, support ring 1 supports electric cylinder 2, electric cylinder 2 pushes push block 3 upward, and push block 3 drives angle sensor 4 to move linkage shaft 5 upward, linkage shaft 5 drives fixed plate 7 upward, fixed plate 7 drives positioning arc strip 28 to move connecting ring 10 upward, connecting ring 10 drives main filter screen 11 to move upward from inside support ring 1. When the bottom end of main filter screen 11 is higher than the top end of support ring 1, the transmission screw 17 is driven by reduction motor 19, and the transmission screw 17 rotates inside slide frame 16.

[0064] The transmission screw 17, carrying the sleeve 18, moves to the right under the action of the threaded transmission force. The sleeve 18, carrying the L-shaped rack 20, moves to the right, and the L-shaped rack 20 drives the gear ring 6 to rotate counterclockwise by 180 degrees. In this way, the gear ring 6 drives the linkage shaft 5 to rotate by 180 degrees. The linkage shaft 5 drives the fixed plate 7 to rotate the positioning arc strip 28. The positioning arc strip 28, carrying the replacement ring 8 and the connecting ring 10, rotates synchronously. The connecting ring 10 drives the main filter screen 11 to move upward, and the replacement filter screen 9 rotates downward. When the angle value sensed by the angle sensor 4 is the same as the angle value set by the controller 12, the controller 12 shuts down the reduction motor 19, and then the electric cylinder 2 drives the push block 3 to move downward. The push block 3, carrying the angle sensor 4, drives the linkage shaft 5 to move downward. The linkage shaft 5 drives the fixed plate 7 to move downward, and the fixed plate 7 drives the connecting ring 10 to move the main filter screen 11 downward. The main filter screen 11 is inserted into the support ring 1, completing the replacement operation of the replacement filter screen 9.

[0065] Step four, during the separation and displacement process, the stepper motor 31 drives the separation screw 30. The separation screw 30 drives the threaded sleeve block 32 to move under the action of thread transmission force. The threaded sleeve block 32 drives the two inserts 33 to move, and the threaded sleeve block 32 moves along the inner wall of the sliding support frame 29. The two inserts 33 move out from inside the fixed plate 7, and the two inserts 33 move to the left and are no longer connected to the positioning arc strip 28. In this way, the separation operation between the positioning arc strip 28 and the fixed plate 7 is completed, and the replacement filter 9 can be quickly removed.

[0066] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and not to limit it. Although the present invention has been described in detail with reference to the above embodiments, those skilled in the art should understand that modifications or equivalent substitutions can still be made to the specific implementation of the present invention. Any modifications or equivalent substitutions that do not depart from the spirit and scope of the present invention should be covered within the scope of protection of the claims of the present invention.
