[0041] The technical solutions in the embodiments of the present application will be described clearly and completely below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all the embodiments.

[0042] Embodiment: The embodiment provides an industrial waste gas treatment high-efficiency energy-saving environmental protection equipment, as shown in Figure 1 - Figure 14, Specifically, it includes dust removal box 1, the top of dust removal box 1 is fixedly installed with clean gas tank 11, the outer end wall of dust removal box 1 is fixedly installed with air pump 12, and the air pump 12 is fixedly connected with air supply pipe 13 extending into clean gas tank 11, a plurality of filter bag mounting holes 14 are throughly arranged in the form of matrix in clean gas tank 11 on the top of dust removal box 1, a filter bag body 15 is installed in each filter bag mounting hole 14, a keel assembly 2 is installed in the filter bag body 15, a dust cleaning mechanism is installed in clean gas tank 11 and arranged above a plurality of filter bag bodies 15, and the dust cleaning mechanism comprises guide rails 3 fixed transversely on the front and back sides in clean gas tank 11, a straight pipe 31 is slidably connected on the guide rails 3 and arranged longitudinally, a flexible pipe 32 is rotatably connected to the front end of the straight pipe 31, the other end of the flexible pipe 32 is rotatably connected with the air supply pipe 13, a plurality of connecting pipes 33 are vertically fixed on the straight pipe 31 and uniformly distributed longitudinally, a blowing pipe 34 is connected in the connecting pipe 33, a plurality of blowing pipes 34 correspond to a plurality of filter bag bodies 15 in the same column one by one, and a driving mechanism for driving the straight pipe 31 to move back and forth is installed in clean gas tank 11.

[0043] The driving mechanism comprises a sliding table 4 slidably installed on the guide rails 3, and the sliding table 4 is connected with the straight pipe 31, a screw rod assembly 41 is rotatably installed in clean gas tank 11 and arranged in parallel with the guide rails 3, and the screw rod assembly 41 is threadedly connected with the sliding table 4, and a first servo motor 42 for driving the screw rod assembly 41 to rotate is fixedly installed on clean gas tank 11.

[0044] When the device is used, the worker uses the device to filter and treat dust in industrial waste gas, the dust removal box 1 is connected with an air inlet pipe, the clean gas tank 11 is connected with an air outlet pipe, the industrial waste gas enters the dust removal box 1 through the air inlet pipe, the filter bag body 15 is supported by the keel assembly 2 and is expanded in the filter bag mounting hole 14, which makes the industrial waste gas in the dust removal box 1 be filtered by the filter bag body 15 when entering the clean gas tank 11 through the filter bag mounting hole 14, with the continuous flow of air flow, the dust in the waste gas is filtered out and adheres to the outer surface of the filter bag body 15, the waste gas after filtering dust can be discharged through the air outlet pipe for subsequent other treatment operations.

[0045] In the continuous operation, the dust in the exhaust gas continuously accumulates on the outer surface of the filter bag body 15, causing the dust on the outer surface of the filter bag body 15 to be too thick, and the subsequent airflow to be difficult to continue to pass through the filter bag body 15 for filtering operation. At this time, the filter bag body 15 needs to be backflushed and cleaned. During the cleaning process, the straight pipe 31 is driven by the driving mechanism to move left and right in the clean gas tank 11 along the guide rail 3. After the first servo motor 42 is energized and started, it will drive the screw rod assembly 41 fixedly connected with the driving shaft to rotate. By means of the screw thread connection between the screw rod assembly 41 and the sliding table 4, the sliding table 4 is driven to move orderly along the guide rail 3. In the device, the screw rod assembly 41 can be set as a reciprocating screw rod, which makes the screw rod assembly 41 rotate to drive the sliding table 4 to move to the end position, and then automatically change direction. Through the continuous rotation of the screw rod assembly 41, the sliding table 4 drives the straight pipe 31 to stably reciprocate in the clean gas tank 11. The movement control of the driving mechanism on the straight pipe 31 will be stopped intermittently, so that the straight pipe 31 can carry the air blowing pipe 34 to temporarily stop on the plurality of filter bag bodies 15 in the same column. During this process, the air pump 12 is energized and started to deliver high-speed and high-pressure airflow outward through the air supply pipe 13. When the air blowing pipe 34 is vertically downward and located directly above the filter bag body 15, the high-pressure airflow enters the straight pipe 31 through the communication of the hose 32, and then is sprayed downward from the air blowing pipe 34 through the connection of the connecting pipe 33, so as to vertically blow the high-speed and high-pressure airflow into the corresponding filter bag body 15, and backflush and clean the filter bag body 15.

[0046] Through the above operation, only a small number of air blowing pipes 34 need to be arranged, and the reciprocating movement of the straight pipe 31 drives the longitudinally uniformly distributed air blowing pipes 34 to blow air in the opposite direction on the filter bag bodies 15 in different columns, so that backflush cleaning of all filter bag bodies 15 can be realized. The use amount of the air blowing pipe 34 can be effectively reduced, so that it is not necessary to arrange one air blowing pipe 34 on each filter bag body 15. Through step-by-step backblowing cleaning, it is not necessary to backflush and supply air to all filter bag bodies 15 at the same time, which can effectively reduce the energy consumption of the air pump 12 in instant use, is helpful for reducing the manufacturing and using costs of the device, and can orderly backblow and clean the plurality of filter bag bodies 15 step by step. The waste gas filtering and backblowing cleaning in the plurality of filter bag bodies 15 can be performed synchronously, which will not cause stagnation influence on the waste gas filtering treatment, and is helpful for guaranteeing the stability and efficiency in the waste gas treatment operation process.

[0047] In the device, in the dust removal tank 1, a partition plate can be arranged between the filter bag bodies 15 in adjacent two columns to separate the filter bag bodies 15 in different columns. This can greatly reduce the probability that the backblowing falling dust adheres to the remaining filter bag bodies 15 in the surrounding columns when the filter bag bodies 15 in different columns are backflushed and cleaned step by step, and is helpful for guaranteeing the effect of air blowing backflush cleaning of the filter bag bodies 15.

[0048] In the specific implementation process, for example, Figure 6- Figure 11 As shown, the keel assembly 2 comprises a first ring plate 21, a second ring plate 22 and a third ring plate 23 arranged in sequence from top to bottom, the first ring plate 21, the second ring plate 22 and the third ring plate 23 are rotationally connected, the bottom of the first ring plate 21 is fixed with a first U-shaped frame 24, the bottom of the second ring plate 22 is fixed with a second U-shaped frame 25, the bottom of the third ring plate 23 is fixed with a third U-shaped frame 26, the second ring plate 22 is provided with a first arc-shaped slot 27 for the first U-shaped frame 24 to pass through, and the third ring plate 23 is provided with a second arc-shaped slot 28 for the first U-shaped frame 24 and the second U-shaped frame 25 to pass through.

[0049] When the device is in use, when the keel assembly 2 is used to support the inside of the filter bag body 15, the cylindrical structure formed by the interweaving of the first U-shaped frame 24, the second U-shaped frame 25 and the third U-shaped frame 26 is supported in the filter bag body 15, so that when the filter bag body 15 is installed inside the filter bag mounting hole 14, it presents a cylindrical structure, and the first ring plate 21, the second ring plate 22 and the third ring plate 23 are arranged above the filter bag mounting hole 14, tightly pressing the bag opening of the filter bag body 15 on the top of the dust removal box 1. In this device, the first ring plate 21, the second ring plate 22 and the third ring plate 23 are coaxially rotationally connected, and the first arc-shaped slot 27 for the first U-shaped frame 24 to move is provided in the second ring plate 22, and the second arc-shaped slot 28 for the first U-shaped frame 24 and the second U-shaped frame 25 to move is provided in the third ring plate 23, which makes the keel assembly 2 can be folded and contracted by rotating when not in use, which is conducive to improving the convenience of the keel assembly 2 during storage and transportation. At the same time, by rotating the first ring plate 21, the second ring plate 22 and the third ring plate 23, the posture of the first U-shaped frame 24, the second U-shaped frame 25 and the third U-shaped frame 26 can be adjusted, so that when the device is loaded into the filter bag body 15, the first U-shaped frame 24, the second U-shaped frame 25 and the third U-shaped frame 26 can be first rotated and contracted, and then expanded after being inserted into the filter bag body 15. When the keel assembly 2 is removed, the first U-shaped frame 24, the second U-shaped frame 25 and the third U-shaped frame 26 can also be first rotated and contracted, and then pulled out, which can effectively improve the operation convenience of the staff inserting the keel assembly 2 into the filter bag body 15 for close support.

[0050] In the specific implementation process, Figure 10 and Figure 11As shown, the first U-shaped frame 24, the second U-shaped frame 25 and the third U-shaped frame 26 are fixed with reinforcing rods 29 evenly distributed from top to bottom, and the three reinforcing rods 29 at the same position in the first U-shaped frame 24, the second U-shaped frame 25 and the third U-shaped frame 26 are hinged to each other, and a torsional spring 210 is installed at the hinge position. When the device is in use, a plurality of reinforcing rods 29 evenly distributed are fixedly connected in the first U-shaped frame 24, the second U-shaped frame 25 and the third U-shaped frame 26, and the three reinforcing rods 29 at the same position are hinged to each other, and the hinge axis is in the same straight line with the rotating axis of the first ring plate 21, the second ring plate 22 and the third ring plate 23. This not only can effectively improve the structural firmness of the keel assembly 2 and the stability of the first U-shaped frame 24, the second U-shaped frame 25 and the third U-shaped frame 26 supporting the inside of the filter bag body 15 in cooperation with each other, but also can guarantee the stability of the relative rotation of the first U-shaped frame 24, the second U-shaped frame 25 and the third U-shaped frame 26. During the above rotation and expansion process, the torsional spring 210 is installed at the hinge position of the three reinforcing rods 29 at the same position in the first U-shaped frame 24, the second U-shaped frame 25 and the third U-shaped frame 26, and the elastic support of the torsional spring 210 makes the first U-shaped frame 24, the second U-shaped frame 25 and the third U-shaped frame 26 can be automatically unfolded under no excessive external force, and can be in a state of uniform circumferential distribution, which can effectively improve the stability of the device for conveniently supporting the inside of the filter bag body 15 through the keel assembly 2.

[0051] In the specific implementation process, as shown in Figure 2 、 Figure 6 and Figure 8 - Figure 9 , the straight pipe 31 is rotationally connected with the sliding table 4, the clean gas tank 11 is fixedly installed with a rack 35 arranged in parallel with the guide rail 3, the first gear 36 engaged with the rack 35 is fixedly installed on the straight pipe 31, and the rubber plug 37 is fixedly installed at the end position of the blowing pipe 34. In the conventional technology, when the filter bag body 15 is subjected to air blowing backflushing cleaning, the bag opening of the filter bag body 15 is in an open state, and the backflushing airflow is sprayed in the filter bag body 15 in the air, which makes part of the backflushing airflow escape through the bag opening of the filter bag body 15, and a more high-speed and high-pressure airflow is required to realize the air blowing cleaning of the filter bag body 15, resulting in excessive energy consumption during the operation of the air pump 12.

[0052] When the device is used, since the straight pipe 31 is rotationally connected with the sliding table 4, and the first gear 36 meshing with the rack 35 is fixed at the end position of the straight pipe 31, in the process of moving the straight pipe 31, the sliding table 4 can drive the straight pipe 31 to rotate by the meshing of the first gear 36 and the rack 35. In the process of moving laterally, the rubber plug 37 fixed at the end position of the blowing pipe 34 can be pressed at the opening in the middle position of the first ring plate 21 by rotating, so as to block the bag opening of the filter bag body 15. When the filter bag body 15 is cleaned by the blowing pipe 34, the airflow blown out of the blowing pipe 34 can be prevented from escaping through the bag opening of the filter bag body 15, so that the backflow airflow can be concentrated in the filter bag body 15. Not only can the effect of cleaning the filter bag body 15 by the airflow be effectively improved, but also the flow rate and pressure required for cleaning the filter bag body 15 by the airflow can be effectively reduced, thereby facilitating the energy consumption of the air pump 12 in use, and realizing the energy-saving cleaning of the filter bag body 15.

[0053] In the specific implementation process, as shown in Figure 6 , Figure 8 and Figure 9 , the blowing pipe 34 is slidingly inserted into the connecting pipe 33, the outer side of the blowing pipe 34 movably sheaths the spring 38 elastically supported between the connecting pipe 33 and the rubber plug 37, the end of the blowing pipe 34 away from the rubber plug 37 is closed, the cylindrical surface of the end of the blowing pipe 34 away from the rubber plug 37 is provided with the air hole 39, and the air hole 39 is in communication with the inside of the blowing pipe 34. When the device is used, in the process of moving the straight pipe 31, the rubber plug 37 is pressed in the opening in the middle position of the first ring plate 21 by the rotation of the straight pipe 31. Since the blowing pipe 34 is slidingly inserted into the connecting pipe 33, the tightness of the rubber plug 37 pressed in the opening in the middle position of the first ring plate 21 can be effectively improved by the elastic support of the spring 38.

[0054] Meanwhile, by opening the air hole 39 on the cylindrical surface of the blowing pipe 34 away from the rubber plug 37, under the elastic support of the spring 38, when the rubber plug 37 is not pressed on the first ring plate 21, the rubber plug 37 keeps the tendency of moving away from the connecting pipe 33 under the elastic support of the spring 38, in this state, the air hole 39 is blocked by the inner end wall of the connecting pipe 33 port, and the airflow conveyed in the straight pipe 31 cannot be sprayed out through the blowing pipe 34, when the rubber plug 37 is pressed on the first ring plate 21 against the elastic support of the spring 38, the blowing pipe 34 moves a distance in the connecting pipe 33 to the straight pipe 31, so that the air hole 39 is exposed in the connecting pipe 33, in this state, the airflow conveyed in the straight pipe 31 can enter the connecting pipe 33, then enter the blowing pipe 34 through the air hole 39, and then be sprayed into the filter bag body 15, the above structure is arranged, so that the device can automatically start the airflow back-flushing when the blowing pipe 34 is precisely connected with the filter bag body 15, and the blowing pipe 34 is in a closed state at other times, which makes the airflow sprayed in the blowing pipe 34 more concentrated, and can realize automatic blowing cleaning operation, which is beneficial to improve the flexibility and stability of the device in actual use.

[0055] In the specific implementation process, as shown in Figure 2 、 Figure 6 - Figure 11 and Figure 14 , the outer side of the first ring plate 21 is fixed with a gear ring 211, the bottom of the third ring plate 23 is fixed with a plug 212 vertically inserted into the top of the dust removal box 1, the top of the dust removal box 1 is rotatably installed with a second gear 5 located in front of each filter bag mounting hole 14 on the left, and the second gear 5 is in meshing connection with the gear ring 211, a plurality of second gears 5 are distributed in a matrix on the top of the dust removal box 1, the top of each second gear 5 in the same column is installed with a transmission shaft 51 arranged in a longitudinal direction, and the transmission shaft 51 is rotatably installed in the clean gas box 11, and the second gear 5 is in driving connection with the corresponding transmission shaft 51 through bevel gear transmission.

[0056] When using this device, before using the air blowing pipe 34 to backflush and clean the filter bag body 15, the first U-shaped frame 24, the second U-shaped frame 25, and the third U-shaped frame 26 inside the keel assembly 2 can be rotated and retracted to release the support inside the filter bag body 15. During this process, the transmission shaft 51 is driven to rotate, and through the bevel gear transmission, multiple second gears 5 on the same longitudinal row are driven to rotate synchronously. By means of the meshing of the second gear 5 with the corresponding gear ring 211 inside the keel assembly 2, the first ring plate 21 can be controlled to rotate. During the rotation of the first ring plate 21 by 120°, the second ring plate 22 can be rotated by the push of the first U-shaped frame 24 in the first arc groove 27, which in turn pushes the second ring plate 22, causing the first ring plate 22 to rotate by 60°. The U-shaped frame 24, the second U-shaped frame 25, and the third U-shaped frame 26 rotate and retract, no longer forming a cylindrical support for the inside of the filter bag body 15. At this time, under the action of the airflow entering the clean air box 11 through the filter bag body 15 in the dust collection box 1, the filter bag body 15 is squeezed from a cylindrical shape to a flat shape. When the rubber plug 37 seals the through hole at the top of the first ring plate 21 and blows air into the inside of the filter bag body 15, the airflow impact pushes the filter bag body 15 outward again. After the backflushing cleaning is completed, the drive of the second gear 5 is released, and it is reset by the elastic support of the torsion spring 210, so that the first U-shaped frame 24, the second U-shaped frame 25, and the third U-shaped frame 26 are re-expanded, supporting the filter bag body 15 into a cylindrical structure, and continuing to filter dust from the exhaust gas.

[0057] When the device performs air backflushing cleaning on the filter bag body 15, it controls the support state of the internal keel assembly 2 of the filter bag body 15. Combined with the backflushing of the airflow in the air blowing pipe 34, the filter bag body 15 changes from a cylindrical shape to a flat shape, and then quickly changes from a flat shape to a cylindrical shape, forming a high-efficiency vibration. This can more efficiently and comprehensively remove the dust accumulated on the outer surface of the filter bag body 15, which is beneficial to improving the dust removal effect of the filter bag body 15 in the device, and thus improving the efficiency of subsequent use of the filter bag body 15 to filter dust in the exhaust gas.

[0058] In this device, by vertically fixing the pin 212 to the bottom of the third ring plate 23 and inserting the pin 212 into the top of the dust collector box 1 while avoiding the filter bag body 15, the position of the keel assembly 2 can be positioned, which helps to ensure the stability of the device in controlling the extension and retraction state of the keel assembly 2 through the meshing of the second gear 5 and the gear ring 211.

[0059] In the specific implementation process, such as Figure 2 , Figure 9 and Figure 13 - Figure 14As shown, the top of the dust removal box 1 is rotatably provided with a third gear 52 at the rear end of each transmission shaft 51, and the rotation axis of the third gear 52 is perpendicular to the rotation axis of the transmission shaft 51, the transmission shaft 51 is drivingly connected with the corresponding third gear 52 through a bevel gear, the clean gas box 11 is rotatably provided with a spline shaft 53 arranged in parallel with the guide rail 3, the clean gas box 11 is fixedly provided with a second servo motor 54 for driving the spline shaft 53 to rotate, the bottom of the sliding table 4 is rotatably connected with a spline barrel 55, and the spline barrel 55 is slidingly arranged outside the second servo motor 54, and the spline barrel 55 is fixedly provided with a fourth gear 56 engaged with the third gear 52.

[0060] When the device is in use, a plurality of second gears 5 in the same column can share a transmission shaft 51 for transmitting rotary power, in the process of moving the straight pipe 31 left and right by moving the sliding table 4 left and right, the spline barrel 55 rotatably arranged at the bottom of the sliding table 4 can be driven to move synchronously, so that when the straight pipe 31 moves left and right to adjust the filter bag body 15 corresponding to different columns, the spline barrel 55 can drive the fourth gear 56 to adaptively engage with the corresponding third gear 52, in the case that the fourth gear 56 and the third gear 52 are engaged, the second servo motor 54 is energized to drive the spline shaft 53 to rotate, since the outer dimension of the spline shaft 53 is adapted to the inner dimension of the spline barrel 55, which enables the spline shaft 53 to drive the spline barrel 55 to rotate during rotation, and then the rotary power is transmitted to the transmission shaft 51 through the engagement of the fourth gear 56 and the third gear 52, thereby providing rotary power for the second gears 5 in the same column, so that the device only needs to be provided with a single second servo motor 54, and the rotary drive of the plurality of second gears 5 in different columns can be gradually realized, the control is more flexible, the use amount of the second servo motor 54 can be greatly reduced, the manufacturing and use cost of the device can be reduced, and efficient and energy-saving waste gas filtration treatment can be realized.

[0061] Specifically, the working principle of the present application is as follows:

[0062] The industrial waste gas passes through the filter bag body 15 installed in the filter bag installation hole 14 in the dust removal box 1, enters the clean gas box 11, and the dust in the waste gas is filtered on the outer surface of the filter bag body 15 in the process of passing through the filter bag body 15. After continuous operation, the accumulation of dust on the outer surface of the filter bag body 15 reduces the actual filtering effect of the filter bag body 15. At this time, the filter bag body 15 can be cleaned by the reverse blowing of the blowing pipe 34. In the operation process, the driving mechanism drives the sliding table 4 to drive the straight pipe 31 to move left and right reciprocally, and the straight pipe 31 can drive the blowing pipe 34 to rotate in the left and right movement process by the meshing of the first gear 36 and the rack 35. The rubber plug 37 fixed at the end of the blowing pipe 34 is gradually pressed in the through hole at the top of the plurality of first ring plates 21, and at the same time, the second servo motor 54 is energized and started to drive the spline shaft 53 to rotate, and then drive the spline barrel 55 sleeved outside the spline shaft 53 to rotate. By the meshing of the fourth gear 56 and the corresponding third gear 52, the transmission shaft 51 is driven to rotate, so that the plurality of second gears 5 in the same column are simultaneously driven to rotate by the meshing of the second gear 5 and the gear ring 211. The first ring plate 21 is driven to rotate by the meshing of the second gear 5 and the gear ring 211, and the first U-shaped frame 24, the second U-shaped frame 25 and the third U-shaped frame 26 in the keel assembly 2 are rotated and contracted, and the support inside the filter bag body 15 is released, so that the filter bag body 15 is converted from a cylindrical shape to a flat shape. Then, the blowing pipe 34 is reversely blown from the bag opening of the filter bag body 15, so that the filter bag body 15 is converted from a flat shape to a cylindrical shape again. The airflow backflushing cooperates with efficient shaking to improve the dust removal effect on the outer surface of the filter bag body 15. In the left and right movement process of the straight pipe 31, the cleaning operation of all filter bag bodies 15 is gradually realized. After the cleaning of the filter bag body 15 is completed, the first U-shaped frame 24, the second U-shaped frame 25 and the third U-shaped frame 26 are kept in the expanded state under the elastic support of the torsional spring 210, and the filter bag body 15 is supported as a stable cylindrical structure, and the efficient filtering operation of the dust in the waste gas is continued.

[0063] The above is only a preferred specific embodiment of the present application, but the protection scope of the present application is not limited thereto. Any skilled person in the art can make equivalent replacement or change according to the technical solution and inventive concept of the present application within the technical range disclosed by the present application, which should be covered within the protection scope of the present application.
