Description

Technical Field

[0001] The present application relates to the technical field of dust removal equipment, and in particular to a bag-type dust collector for an air-cooling section of a continuous annealing furnace. Background Art

[0002] The bag-type dust collector in the air-cooling section of the continuous annealing furnace is a dust removal device installed in the air-cooling section of the continuous annealing furnace. It filters the dust-laden flue gas through the filter bags, and uses the interception effect of the bags to capture the iron oxide scale, dust and other particulate matter generated during the air-cooling process. The dust attached to the surface of the filter bags is peeled off by the cleaning system and discharged from the ash outlet, thereby purifying the flue gas, ensuring that the production environment and emissions of the air-cooling section meet environmental protection requirements, and ensuring the normal operation of the annealing furnace system.

[0003] After the dust-laden flue gas enters the bag-type dust collector, the airflow forms turbulence or eddy currents at corners, filter bag gaps and other locations. The dust is separated from the mainstream airflow and deposited by inertia and gravity. If the dust itself is sticky or has a small particle size, it is easy to adhere to or diffuse on the inner wall of the bag-type dust collector. Long-term use will cause dust adhesion. In some existing technologies, the bag-type dust collector does not have a mechanism for self-cleaning the inner wall. The operator needs to manually clean the dust on the inner wall of the bag-type dust collector, which is labor-intensive and troublesome. Therefore, a bag-type dust collector for the air cooling section of a continuous annealing furnace is proposed to address the above problems. Summary of the Invention

[0029] The following combination Figures 1 to 8 , further details of this application are given.

[0030] Example 1

[0031] A bag type dust collector for the air cooling section of a continuous annealing furnace, Figures 1 to 8 , including a shell 1, and also including: a cleaning mechanism 2, the cleaning mechanism 2 is arranged inside the shell 1; a vibration mechanism 3, the vibration mechanism 3 is arranged on the outer wall of the shell 1; a filtering mechanism 4, the filtering mechanism 4 is arranged on the bottom outer wall of the shell 1; a waterproof module 6, the waterproof module 6 is fixedly connected to the outer wall of the shell 1, the outer wall of the waterproof module 6 is fixedly connected to the air inlet 5, and the outer wall of the shell 1 is fixedly connected to the air outlet 7;

[0032] Among them, the cleaning mechanism 2 includes a motor 21, and the output shaft of the motor 21 is fixedly connected to the rotating rod 27; the vibration mechanism 3 includes a fixed rod 31, and the outer wall of the fixed rod 31 is rotatably connected to the knocking block 34; the filtering mechanism 4 includes a mounting block 41, and the inner wall of the mounting block 41 is provided with a screen 46.

[0033] The above scheme is adopted: the shell 1 is the main body of the bag-type dust collector for the continuous annealing furnace, the air inlet 5 on its outer wall can be connected to the air outlet of the continuous annealing furnace, and the air outlet 7 is the outlet of the gas after dust removal. After the gas containing oil and impurities enters from the air inlet 5, the moisture in the gas is removed by the waterproof module 6 with aluminum oxide particles inside, and then the dust is removed and discharged through multiple groups of dust collecting bags 8 inside the shell 1. The aluminum oxide particles effectively capture moisture in the air through physical adsorption, preventing moisture from entering the shell 1, thereby protecting the inner wall of the shell 1 from rust and extending the service life of the equipment. It has certain stability and durability, high density, and is not easily affected by the impact of airflow, ensuring its effect in long-term operation; the cleaning mechanism 2 can make the scraper 23 rotate along the inner wall of the shell 1 to remove the shell The dust attached to the inner wall of the shell 1 is scraped off and discharged from the dust outlet at the bottom of the shell 1, and the cleaning mechanism 2 can drive multiple groups of dust collecting bags 8 to rotate synchronously, so that the multiple groups of dust collecting bags 8 correspond to the air inlet 5 in turn, avoiding the problem that there is more dust on the dust collecting bags 8 on the side close to the air inlet 5 and less dust on the other side due to the fixed position of the dust collecting bags 8, which affects the initial dust removal effect, and is more uniform; and in the process of the cleaning mechanism 2 scraping the dust on the inner wall of the shell 1, the vibration mechanism 3 can continuously knock on the outer wall of the shell 1, so that the dust is separated from the inner wall of the shell 1 under vibration, which helps to improve the cleaning effect; the cleaned dust is discharged through the dust outlet below, and the filtering mechanism 4 can filter out larger slag fragments or other impurities in the gas to avoid clogging of subsequent dust collection devices.

[0034] Reference Figures 3 to 5 The inner wall of the rotating rod 27 is slidably connected to the moving rod 26, the outer wall of the moving rod 26 is fixedly connected to the pull rod 28, the inner wall of the rotating rod 27 is hinged with the scraper 23 through the support rod 22, the support rod 22 is hinged to the inner wall of the rotating rod 27 through the hinge rod 24, the outer wall of the rotating rod 27 is slidably connected to the telescopic rod 25, the inner wall of the moving rod 26 is elastically connected to the protrusion 202 through the elastic part A201, the outer wall of the rotating rod 27 is provided with a groove 203, and the outer wall of the rotating rod 27 is fixedly connected to the dust collecting bag 8.

[0035] The above scheme is adopted: the moving rod 26 can move up and down in the inner wall of the rotating rod 27 but cannot rotate. The rotating rod 27 can be driven by the motor 21 to rotate in the inner wall of the shell 1, and drive the support rod 22 and the scraper 23 to rotate synchronously. The scraper 23 can be retracted or unfolded. After unfolding, it can contact the inner wall of the shell 1 and be driven by the rotating rod 27 to rotate along the inner wall of the shell 1, so as to scrape and clean the dust attached to the inner wall of the shell 1. When retracted, it does not contact the inner wall of the shell 1, avoiding the wear caused by long-term contact and friction with the inner wall of the shell 1; multiple groups of dust collecting bags 8 are provided on the outer wall of the rotating rod 27. After the exhaust gas containing dust enters the shell 1 from the air inlet 5, it is dust-removed by the dust collecting bags 8. During the dust removal process, the motor 21 is started to rotate the multiple groups of dust collecting bags 8, which take turns to correspond to the position of the air inlet 5, so as to avoid the problem that the dust collecting bags 8 close to the air inlet 5 are affected too much by dust due to fixed position and reduce the effect, and the scraper 23 can be retracted to avoid wear during dust removal.

[0036] Reference Figures 3 to 5 The motor 21 is fixedly connected to the top outer wall of the shell 1, the rotating rod 27 is rotatably connected to the top inner wall of the shell 1, the pull rod 28 is slidingly connected to the inner wall of the rotating rod 27, one end of the support rod 22 is hinged to the inner wall of the scraper 23, and the other end of the support rod 22 is hinged to the inner wall of the rotating rod 27; one end of the hinged rod 24 is hinged to the outer wall of the moving rod 26, and the other end of the hinged rod 24 is hinged to the inner wall of the support rod 22, and the movable end of the telescopic rod 25 is fixedly connected to the outer wall of the scraper 23; one end of the elastic part A201 is fixedly connected to the outer wall of the protrusion 202, and the other end of the elastic part A201 is fixedly connected to the inner wall of the moving rod 26, the protrusion 202 is slidably connected in the inner wall of the moving rod 26, and the protrusion 202 is engaged with the groove 203.

[0037] The above scheme is adopted: the operator can pull the pull rod 28 to drive the moving rod 26 to move up and down in the inner wall of the rotating rod 27. The groove 203 on the outer wall of the rotating rod 27 is provided with two groups of upper and lower grooves. Under normal circumstances, the protrusion 202 remains in a pop-up state due to the elastic force of the elastic member A201 and is engaged with a group of grooves 203 to limit the moving rod 26. When the moving rod 26 needs to be moved up and down, the protrusion 202 can be pressed to move it into the inner wall of the moving rod 26, and the elastic member A201 can be compressed to release the limit of the moving rod 26 and move it up and down; when the moving rod 26 moves, it will drive one end of the hinged rod 24 hinged thereto to move up and down synchronously, and the other end of the hinged rod 24 drives the support rod 22 to flip, and the support rod 22 drives the scraper 23 to move. Since the telescopic rod 25 can move up and down on the outer wall of the rotating rod 27, and the telescopic rod 25 can move up and down, the telescopic rod 25 can move up and down. The retractable rod 25 can play a horizontal guiding role for the scraper 23, so that when the moving rod 26 moves up and down, the scraper 23 can maintain a vertical state and move diagonally upward or downward by flipping the hinge rod 24 and the support rod 22. During the movement, the scraper 23 will drive the telescopic rod 25 to move up and down synchronously; when the moving rod 26 moves to the point where the protrusion 202 is engaged with the upper groove 203, the hinge rod 24 and the support rod 22 can drive the scraper 23 to move outward so that it fits the inner wall of the shell 1. Conversely, when the protrusion 202 is engaged with the lower groove 203, the hinge rod 24 and the support rod 22 will drive the scraper 23 to move inward and retract. The protrusion 202 can be popped out and stuck in the corresponding groove 203 by the elastic force of the elastic part A201. The operation is simple and quick, and the operator does not need to manually clean the inner wall of the shell 1, which is convenient for use.

[0038] Reference Figures 6 and 7 The outer wall of the fixed rod 31 is elastically connected to the stopper 32 through a spiral spring 33, the outer wall of the bottom end of the stopper 32 is fixedly connected to the connecting rod 35, the outer wall of the rotating rod 27 is fixedly connected to the sleeve rod 39, the outer wall of the sleeve rod 39 is provided with a square groove 30, the inner wall of the sleeve rod 39 is slidably connected to the inner rod 36, and the inner wall of the inner rod 36 is elastically connected to the square block 38 through an elastic member B37.

[0039] The above scheme is adopted: the stopper 32 is kept in a certain position under normal conditions due to the elastic force of the spiral spring 33, and it corresponds to the position of the inner rod 36. When the rotating rod 27 rotates, the sleeve rod 39 and the inner rod 36 are driven to rotate synchronously; the stopper 32 can rotate a certain angle under the influence of the inner rod 36, and drive the knocking block 34 below to rotate synchronously through the connecting rod 35, and the knocking block 34 always keeps contact with the outer wall of the shell 1 under normal conditions. When it rotates, it will disengage from the outer wall of the shell 1, and the knocking block 34 can knock the outer wall of the shell 1, generating vibration to help shake off the dust on the inner wall of the shell 1; and the position of the inner rod 36 in the inner wall of the sleeve rod 39 is adjustable. When the combined length of the inner rod 36 and the sleeve rod 39 is shortened, the inner rod 36 will not contact the stopper 32 during its rotation, that is, it will not be affected by the inner rod 36 and rotate, and when the combined length of the two increases, the stopper 32 will be driven to rotate through the inner rod 36.

[0040] Reference Figures 6 and 7 The fixing rod 31 is fixedly connected to the outer wall of the shell 1, and the two ends of the spiral spring 33 are respectively fixedly connected to the stopper 32 and the outer wall of the fixing rod 31. The stopper 32 is rotatably connected to the outer wall of the fixing rod 31. One end of the elastic member B37 is fixedly connected to the outer wall of the square block 38, and the other end of the elastic member B37 is fixedly connected to the inner wall of the inner rod 36. The square block 38 is slidably connected to the inner wall of the inner rod 36. The square block 38 is engaged with the square groove 30, and the connecting rod 35 is fixedly connected to the outer wall of the knocking block 34.

[0041] The above scheme is adopted: the inner rod 36 can be fixed in the inner wall of the sleeve rod 39 by snapping the square block 38 of its inner wall with the square groove 30. The square groove 30 is provided with two groups. When the square block 38 is snapped with one group of square grooves 30, the combined length of the inner rod 36 and the sleeve rod 39 becomes longer, and the sleeve rod 39 and the inner rod 36 rotate with the rotating rod 27. The inner rod 36 will continuously contact the outer wall of the stopper 32 and rotate it to a certain angle. The spiral spring 33 is forced to shrink, and the stopper 32 drives the knocking block 34 to rotate synchronously, and the knocking block 34 is out of contact with the outer wall of the shell 1. When the inner rod 36 continues to rotate until it is out of contact with the stopper 32, the stopper 32 rotates in the opposite direction and resets under the elastic force of the spiral spring 33, and the knocking block 34 is 4 rotates synchronously and knocks on the outer wall of the shell 1, so that when the inner rod 36 is constantly in contact with the outer wall of the stopper 32, the knocking block 34 can continuously hit the outer wall of the shell 1 to generate vibration; and when the square block 38 is pressed to disengage it from the square groove 30 and the inner rod 36 is moved toward the inside of the sleeve rod 39, when the square block 38 is engaged with another set of square grooves 30, the inner rod 36 will not contact the stopper 32 during the rotation process and will not knock on the outer wall of the shell 1. Therefore, when the scraper 23 in the cleaning mechanism 2 is unfolded for cleaning, the state of the vibration mechanism 3 can be adjusted to assist in shaking off the dust, thereby avoiding the problem of the outer wall of the shell 1 being damaged due to continuous knocking and improving the dust cleaning efficiency.

[0042] Example 2

[0043] Reference Figure 8 The inner wall of the mounting block 41 is elastically connected to the partition 43 through the return spring A42, the inner wall of the mounting block 41 is elastically connected to the wedge block 45 through the return spring B44, and the outer wall of the mounting block 41 is rotatably connected to the cover plate 47.

[0044] Adopting the above scheme: the screen 46 can filter out larger slag fragments or other impurities in the dust to avoid affecting the clogging of subsequent dust collection equipment, and the setting of the filtering mechanism 4 can be used without stopping the operation of the shell 1 when replacing the screen 46. When the new screen 46 is inserted, the screen 46 that needs to be replaced can automatically pop out, which is more convenient and avoids the need to stop the operation of the shell 1 before replacing the screen 46 with bolts, which is inefficient; the reset spring A42 and the partition 43 are provided with two groups, upper and lower, and the screen 46 can be placed on both groups of partitions 43. The cover 47 at the front end of the mounting block 41 can be opened and closed by magnetic attraction or other existing technologies to prevent the screen 46 from falling off. After opening the cover 47, the screen 46 can be replaced.

[0045] Reference Figure 8 The mounting block 41 is fixedly connected to the outer wall of the bottom end of the shell 1, one end of the return spring A42 is fixedly connected to the outer wall of the partition 43, the other end of the return spring A42 is fixedly connected to the inner wall of the mounting block 41, and the screen 46 contacts the outer wall of the partition 43; one end of the return spring B44 is fixedly connected to the outer wall of the wedge block 45, the other end of the return spring B44 is fixedly connected to the inner wall of the mounting block 41, the wedge block 45 is slidably connected to the inner wall of the mounting block 41, and the wedge block 45 contacts the outer wall of the partition 43.

[0046] The above solution is adopted: among the two groups of partitions 43, there is always one group that fits with the straight surface of the wedge block 45, and the return spring A42 corresponding to the group of partitions 43 remains in a contracted state, and the screen 46 is placed on the group of partitions 43 for use; while the other group of partitions 43 fits with the curved surface of the wedge block 45, and the return spring A42 of this group is in a normal state. When the screen 46 needs to be replaced, the cover 47 can be fully opened first, and the new screen 46 can be inserted into the normal partition 43 and pressed inward, so that the group of partitions 43 squeezes the curved surface of the wedge block 45, and the wedge block 45 moves toward the inner wall of the mounting block 41 and compresses the return spring B44. When the new screen 46 drives the partition 43 to move to disengage from the arc surface of the wedge block 45, the wedge block 45 pops out under the elastic force of the reset spring B44, and its straight surface contacts the group of partitions 43, limiting it, and the new screen 46 can be installed. The partition 43 corresponding to the old screen 46 is now at the arc surface of the wedge block 45, that is, a switch is completed, which is simple to operate and saves time and effort.

[0047] The use process and working principle of the present invention:

[0048] When the shell 1 is in normal use, the scraper 23 of the cleaning mechanism 2 is in the retracted state, the protrusion 202 is engaged with the groove 203 below the rotating rod 27, the combined length of the inner rod 36 and the sleeve rod 39 of the vibration mechanism 3 is shortened, and the inner rod 36 will not trigger the rotation of the stopper 32. The annealing furnace flue gas containing oil, water vapor and dust enters from the air inlet 5, first passes through the waterproof module 6, and the aluminum oxide particles remove moisture in the flue gas by physical adsorption to prevent water vapor from entering the inner wall of the shell 1 and causing rust. The dried flue gas enters the inside of the shell 1, and the dust is intercepted by the dust collecting bag 8. The clean flue gas is discharged from the air outlet 7 through the filter bag. The motor 21 drives the rotating rod 27 to rotate and drives the dust collecting bag 8 to rotate synchronously, so that each group of dust collecting bags 8 corresponds to the position of the air inlet 5 in turn to avoid overload and dust accumulation of local dust collecting bags 8.

[0049] When the shell 1 stops running, the operator can press the protrusion 202 to disengage it from the lower groove 203, and then pull the pull rod 28 upward to drive the movable rod 26 to move until the protrusion 202 is engaged in the upper groove 203. At this time, the hinged rod 24 drives the support rod 22 to flip, and the support rod 22 and the telescopic rod 25 drive the scraper 23 to maintain a vertical state, expand outward and fit against the inner wall of the shell 1; then press the square block 38 to disengage it from one group of square grooves 30 of the sleeve rod 39, pull the inner rod 36 outward, and make the square block 38 engage in another group of square grooves 30. At this time, the combined length of the inner rod 36 and the sleeve rod 39 becomes longer.

[0050] At this time, the motor 21 drives the rotating rod 27 to drive the scraper 23 to rotate along the inner wall of the shell 1, scraping the accumulated dust to the ash outlet below to complete the cleaning; the rotating rod 27 will simultaneously drive the sleeve rod 39 and the inner rod 36 to rotate, and the inner rod 36 periodically contacts the stopper 32, pushing it to rotate around the fixed rod 31, the spiral spring 33 is compressed, and the knocking block 34 is out of contact with the outer wall of the shell 1; when the inner rod 36 is out of contact with the stopper 32, the spiral spring 33 is reset, and the stopper 32 drives the connecting rod 35 and the knocking block 34 to knock on the outer wall of the shell 1, and the vibration causes the residual dust on the inner wall of the shell 1 to fall off, assisting the scraper 23 to improve the cleaning efficiency.

[0051] The scraped dust and possible slag fragments enter the filter mechanism 4 from the ash outlet below the shell 1, and the screen 46 intercepts large particles of impurities, and fine dust passes through the screen and falls into the downstream ash discharge device; when the screen 46 is blocked by impurities and needs to be replaced, the cover 47 can be opened without stopping the operation of the shell 1, and the new screen 46 can be inserted into the partition 43 to be replaced and pressed inward, and the partition 43 squeezes the arc surface of the wedge block 45, and the wedge block 45 compresses the reset spring B44 to move inward, and the original working position partition 43 loses the wedge block 45 directly facing the limit, and pops out under the elastic force of the reset spring A42, driving the old screen 46 to automatically pop out, and it can be taken out and cleaned; the new screen 46 pushes the partition 43 to the position facing the wedge block 45, and the wedge block 45 resets the limit to the partition 43, so that the replacement of the screen 46 can be completed conveniently and quickly, and the dust removal work can be continued by closing the cover 47.
