Description

Technical Field

[0001] This utility model relates to the field of waste gas treatment technology, specifically to a device for the safe treatment of chemical waste gas filtration. Background Technology

[0002] Waste gas purification mainly refers to the treatment of industrial waste gases generated in industrial sites, such as particulate matter, flue gas, odorous gases, and toxic and harmful gases. Common waste gas purification methods include factory flue gas purification, workshop dust gas purification, organic waste gas purification, odor removal, acid and alkali waste gas purification, and chemical waste gas purification.

[0003] The waste gas generated by chemical equipment needs to be treated by waste gas treatment devices. Current waste gas treatment devices generally include filtration devices, photoprocessors, condensation chambers, adsorption chambers, and recovery and treatment devices. The filtration devices mainly consist of filter boxes used to filter dust particles in the waste gas. These filter boxes are equipped with filter plates for dust removal. However, existing chemical processing waste gas filter plates accumulate a large amount of dust over time, reducing their filtration efficiency. Therefore, the filter plates need to be disassembled and cleaned periodically. During the disassembly and cleaning process, continuous filtration of the waste gas is interrupted, resulting in some unfiltered waste gas being directly discharged into subsequent treatment processes.

[0010] Furthermore, a non-circular insert rod is connected to the output shaft of the first motor, and the insert rod is arranged along the center line of the filter barrel. The bottom surface of the rotating shaft is recessed to form a slot that can slide with the insert rod, and the insert rod is inserted into the slot.

[0011] Furthermore, the rotating shaft is slidably mounted on the upper and lower side walls of the filter barrel. The rotating part also includes a connecting rod reciprocating mechanism, which is connected to the top of the rotating shaft and is used to drive the rotating shaft to slide up and down along the insert rod.

[0012] Furthermore, the reciprocating linkage mechanism includes a second motor, a first connecting rod, a second connecting rod, and a pulling rod.

[0013] Furthermore, the cleaning unit includes a cleaning brush, which is fixed to the wall of the filter barrel and arranged along the radius of the filter plate, with the brush bristles abutting against the lower side of the filter plate.

[0014] Furthermore, the cleaning unit includes a cleaning brush and a fan-shaped reciprocating mechanism. The fan-shaped reciprocating mechanism is used to connect the cleaning brush to the filter barrel, and the cleaning brush abuts against the lower side of the filter plate.

[0030] Example 1

[0031] Please see Figure 1-5This utility model provides a technical solution: a safety treatment device for filtering chemical waste gas, including a filter barrel 1, a filter plate 2, and a partition 3. The filter plate 2 is horizontally arranged inside the filter barrel 1 and cooperates with the inner cavity of the filter barrel 1. The filter plate 2 is horizontally rotatable inside the filter barrel 1 and divides the filter barrel 1 into an upper chamber and a lower chamber. The upper chamber is provided with an air outlet 42 at its upper end. The lower chamber is provided with a partition 3, which divides the lower chamber into a first chamber and a second chamber. The lower end of the first chamber is provided with an air inlet 41. The second chamber is provided with a cleaning part for cleaning the lower side of the filter plate 2.

[0032] When using the chemical waste gas filtration and safety treatment device described in this utility model to filter chemical waste gas, the chemical waste gas enters the first chamber through the air inlet 41. Then, the chemical waste gas in the first chamber passes through the filter plate 2 and the upper chamber in sequence and is discharged from the air outlet 42. When the chemical waste gas passes through the filter plate 2, the filter plate 2 can filter the chemical waste gas so that the dust particles in the chemical waste gas are blocked on the lower side of the filter plate 2.

[0033] During the filtration of chemical waste gas by filter plate 2, by continuously rotating filter plate 2, various parts of the lower side of filter plate 2 can continuously circulate into the upper side of the second chamber, ensuring that each part of the lower side of filter plate 2 is cleaned by the cleaning section within the second chamber. While one part of the lower side of filter plate 2 is being cleaned by the cleaning section, another part of filter plate 2 continuously filters the chemical waste gas entering the upper chamber from the first chamber. During the cleaning process of filter plate 2, unfiltered waste gas is not easily discharged directly into subsequent treatment processes.

[0034] Under the separation effect of the partition plate 3, the dust particles cleaned off the filter plate 2 by the cleaning brush can fall to the bottom wall of the second chamber, making it difficult for the dust particles on the filter plate 2 to enter the first chamber, and reducing the possibility that the cleaned dust particles will re-adhere to the lower side of the filter plate 2.

[0035] In this embodiment, a driving mechanism is also included. The driving mechanism is connected to the filter plate 2 and is used to drive the filter plate 2 to rotate in the horizontal direction.

[0036] The filter plate 2 is driven to rotate in the horizontal direction by the drive mechanism, which makes it more convenient to rotate the filter plate 2.

[0037] In this embodiment: the driving mechanism includes a rotating part and a first motor 51. The rotating part is arranged along the center line of the filter barrel 1 and is rotatably connected to the top and bottom walls of the filter barrel 1. The rotating part is connected to the filter plate 2. The rotating part can drive the filter plate 2 to rotate in the horizontal direction when rotating. The first motor 51 is used to drive the rotating part to rotate. The first motor 51 can be an ultra-low speed motor of model YDS-56.

[0038] Start the first motor 51, which drives the rotating part to rotate, thereby causing the filter plate 2 to rotate in the horizontal direction. With this structure, the driving mechanism can drive the filter plate 2 to rotate in the horizontal direction.

[0039] In this embodiment: the rotating part includes a rotating shaft 6, which passes through the filter plate 2 and is arranged along the center line of the filter barrel 1. The rotating shaft 6 is rotatably connected to the top and bottom walls of the filter barrel 1. A bevel gear 61 is provided below the filter plate 2 on the rotating shaft 6. The filter plate 2 is provided with a slot 62 that cooperates with the bevel gear 61. The slot 62 is located directly above the bevel gear 61. The first motor 51 is used to drive the rotating shaft 6 to rotate.

[0040] Since the bevel gear 61 is inserted into the slot 62, the first motor 51 drives the rotating shaft 6 to rotate, which in turn drives the filter plate 2 to rotate in the horizontal direction. Thus, the rotating part can drive the filter plate 2 to rotate in the horizontal direction when it rotates.

[0041] In this embodiment: a non-circular insert rod 7 is connected to the output shaft of the first motor 51, and the insert rod 7 is arranged along the center line of the filter barrel 1. The bottom surface of the rotating shaft 6 is recessed to form a slot that can slide with the insert rod 7, and the insert rod 7 is inserted into the slot.

[0042] The insertion rod 7 can be a square-shaped insertion rod 7. It is understood that in other embodiments, the insertion rod 7 can also be a non-circular insertion rod 7. With this structure, the insertion rod 7 can cooperate with the slot without relative rotation. That is, the rotating shaft 6 can slide up and down on the insertion rod 7 without relative rotation with the insertion rod 7. When the first motor 51 is started, the first motor 51 can drive the rotating shaft 6 to rotate.

[0043] In this embodiment: the rotating shaft 6 is slidably mounted on the upper and lower side walls of the filter barrel 1. The rotating part also includes a connecting rod reciprocating mechanism, which is connected to the top of the rotating shaft 6. The connecting rod reciprocating mechanism is used to drive the rotating shaft 6 to slide up and down along the insertion rod 7.

[0044] During the operation of the first motor 51, the insertion rod 7 can continuously rotate under the drive of the first motor 51, thereby driving the rotating shaft 6 and the filter plate 2 to rotate continuously. During the rotation of the filter plate 2, the lower side of the filter plate 2 can be relatively displaced with the cleaning part, and the cleaning part can clean the lower side of the filter plate 2. After the cleaning part cleans the lower side of the filter plate 2 for a period of time, the rotating shaft 6 moves downward, causing the bevel gear 61 to disengage from the slot 62. At this time, the rotating shaft 6 can no longer drive the filter plate 2 to rotate, and the filter plate 2 stops rotating. At this time, the lower side of the filter plate 2 will not move relative to the cleaning part, and the cleaning part stops cleaning the filter plate 2. After the filter plate 2 located at the top of the first chamber has filtered for a period of time, the rotating shaft 6 slides upward, causing the bevel gear 61 to insert into the slot 62. At this time, the bevel gear 61 and the slot 62 cooperate, and the rotating shaft 6 can drive the filter plate 2 to rotate again. The lower side of the filter plate 2 can be relatively displaced with the cleaning part again, and the cleaning part continues to clean the lower side of the filter plate 2. By alternately moving the rotating shaft 6 up and down, the filter plate 2 of the cleaning section can be cleaned intermittently, which can reduce the possibility of the filter plate 2 being damaged by brushing.

[0045] The connecting rod reciprocating mechanism can drive the rotating shaft 6 to achieve up-and-down reciprocating motion, making it more convenient to make the rotating shaft 6 move up and down alternately.

[0046] In this embodiment: the reciprocating linkage mechanism includes a second motor 52, a first connecting rod 81, a second connecting rod 82, and a pulling rod 9. The first connecting rod 81 is arranged perpendicular to the output shaft of the second motor 52, and one end of the first connecting rod 81 is fixedly connected to the output shaft of the second motor 52. The other end of the first connecting rod 81 is hinged to one end of the second connecting rod 82, and the other end of the second connecting rod 82 is hinged to the top of the pulling rod 9. The pulling rod 9 is rotatably connected to the rotating shaft 6.

[0047] The second motor 52 drives the first connecting rod 81 to rotate around the output shaft of the second motor 52, causing the end of the first connecting rod 81 away from the output shaft of the second motor 52 to move in a circle along the output shaft of the second motor 52, thereby driving the second connecting rod 82 to move in a circle. When the second connecting rod 82 rotates with the end of the first connecting rod 81 away from the output shaft of the second motor 52 to the lowest point of the circle, the second connecting rod 82 pushes the pulling rod 9 to the lowest position. At this time, the rotating shaft 6 slides to the lowest position relative to the insertion rod 7. At this time, the bevel gear 61 is disengaged from the slot 62, and the rotating shaft 6 cannot drive the filter plate 2 to rotate. When the second connecting rod 82 rotates upward from the lowest point of the circle with the end of the first connecting rod 81 away from the output shaft of the second motor 52, the second connecting rod 82 pulls the pulling rod 9 upward, and at the same time pulls the rotating shaft 6 to drive the bevel gear 61 to move upward, until the second connecting rod 81 rotates upward. When the first connecting rod 82 rotates to the highest point of the circumference at the end away from the output shaft of the second motor 52, the bevel gear 61 on the rotating shaft 6 inserts into the slot 62 on the filter plate 2. At this time, the rotating shaft 6 will drive the filter plate 2 to rotate at a certain angle. After that, the second connecting rod 82 continues to rotate downward from the highest point of the circumference at the end away from the output shaft of the second motor 52, and the bevel gear 61 on the rotating shaft 6 gradually disengages from the slot 62 on the filter plate 2. The rotating shaft 6 gradually returns to the state where it can no longer drive the filter plate 2 to rotate. This process is repeated, and with this structure, the filter plate 2 is driven to rotate intermittently.

[0048] A first rotating shaft is provided at the end of the first connecting rod 81 away from the second motor 52 along the output shaft direction of the second motor 52. A first shaft hole is provided at the junction of the second connecting rod 82 and the first connecting rod 81, which mates with the first rotating shaft. The second connecting rod 82 can rotate relative to the first connecting rod 81 through the engagement of the first rotating shaft and the first shaft hole. A second shaft hole is provided at the end of the second connecting rod 82 that connects to the pull rod 9. A second shaft is provided at the upper end of the pull rod 9. The second shaft hole allows the second connecting rod 82 to rotate relative to the pull rod 9 through the engagement of the second shaft. With this structure, the first connecting rod 81 can drive the pull rod 9 to move up and down while rotating with the output shaft of the second motor 52, thereby realizing the up and down movement of the rotating shaft 6.

[0049] The output shaft of the second motor 52 and the pulling rod 9 are located on the same vertical line, and the pulling rod 9 and the rotating shaft 6 are rotatably connected through a bearing. The bottom of the pulling rod 9 is connected to the outer end of the bearing, and the rotating shaft 6 is connected to the inner end of the bearing. With this structure, the rotating shaft 6 can continue to rotate while being pulled up and down along the direction of the insertion rod 7.

[0050] In this embodiment: the cleaning part includes a cleaning brush 10, which is fixed to the wall of the filter barrel 1 and arranged along the radius of the filter plate 2, and the bristles of the cleaning brush 10 abut against the lower side of the filter plate 2.

[0051] When the filter plate 2 rotates, the filter plate 2 and the cleaning brush 10 move relative to each other. The filter brush will sweep against the lower side of the filter plate 2 as it passes through, thus cleaning the filter plate 2.

[0052] Specifically, a dust collection box 15 can be set at the bottom of the filter bucket 1. When the cleaning brush 10 cleans the lower side of the filter plate 2, the powdery particles on the lower side of the filter plate 2 will detach from the lower side of the filter plate 2 and gradually fall to the bottom of the filter bucket 1. By setting a dust collection box 15 at the bottom of the filter bucket 1, it is convenient to collect the powdery particles. After collecting for a period of time, the dust collection box 15 can be removed for cleaning, which is easy to operate.

[0053] Example 2

[0054] The difference between this embodiment and Embodiment 1 is that the cleaning brush 10 is disposed in the second chamber in a different way, and this embodiment also includes a fan-shaped reciprocating mechanism; the rest are the same as in Embodiment 1.

[0055] Specifically, the cleaning unit includes a cleaning brush 10 and a fan-shaped reciprocating mechanism. The fan-shaped reciprocating mechanism is used to connect the cleaning brush 10 to the filter barrel 1. The cleaning brush 10 abuts against the lower side of the filter plate 2. The fan-shaped reciprocating mechanism is also used to drive the cleaning brush 10 to swing back and forth in the horizontal direction.

[0056] After the filter plate 2 at the top of the first chamber adsorbs the dust particles in the chemical waste gas, it rotates to the top of the second chamber. The fan-shaped reciprocating mechanism drives the cleaning brush 10 to swing back and forth in the horizontal direction to sweep the powdery particles attached to the lower side of the filter plate 2, thereby breaking up the powdery particles on the lower side of the filter plate 2 and removing them from the lower side of the filter plate 2, thus cleaning the lower side of the filter plate 2.

[0057] In this embodiment: the fan-shaped reciprocating mechanism includes a third motor 53, a torsion spring 11, a connecting rod 14, a half gear 13, and a gear 12. The connecting rod 14 passes through the bottom wall of the filter barrel 1 and is arranged along the center line of the filter barrel 1. The top end of the connecting rod 14 is connected to the cleaning brush 10, and the bottom end is connected to the gear 12. The center line of the gear 12 is located at the center line of the connecting rod 14. One end of the torsion spring 11 is connected to the gear 12, and the other end of the torsion spring 11 is fixed to the filter barrel 1. The half gear 13 meshes with the gear 12 and is connected to the output shaft of the third motor 53. The third motor 53 is connected to the filter barrel 1.

[0058] The half-gear 13 has one half with a toothed key and the other half without. The toothed half of the half-gear 13 can mesh with the gear 12. The third motor 53, which can be an ultra-low speed motor (YDS-56), is activated, driving the half-gear 13 to rotate continuously in a certain direction. When the toothed half-gear 13 meshes with the gear 12, it drives the gear 12 to rotate in the forward direction. At this time, the torsion spring 11 is stressed and accumulates a rebound force. Due to the resistance of the toothed key of the half-gear 13, the rebound force of the torsion spring 11 cannot be released. At this time, the gear 12 drives the connecting rod 14 to rotate in the forward direction, thereby driving the cleaning brush 10 to move forward along the horizontal plane to sweep the lower side of the filter plate 2. When the half-gear 1... 3. Continue rotating until it reaches halfway point where it can no longer mesh with gear 12. At this point, the resistance force of the half gear 13 against gear 12 is released, and gear 12 is only driven to reset by the rebound force of torsion spring 11. That is, gear 12 rotates in the opposite direction. At this time, gear 12 drives connecting rod 14 to rotate in the opposite direction, thereby driving cleaning brush 10 to move in the opposite direction along the horizontal plane to sweep the lower side of filter plate 2 in the opposite direction. During the continuous rotation, half gear 13 meshes with gear 12 in this way periodically. Torsion spring 11 drives gear 12 to reset periodically and rotates gear 12 periodically. This can drive cleaning brush 10 to perform periodic reciprocating motion, so that cleaning brush 10 can have a better cleaning effect on the lower side of filter plate 2.

[0059] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the spirit and scope of the technical solutions of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
