Description

Technical Field

[0001] The present invention relates to the technical field of fans, and specifically to an efficient tail gas treatment fan. Background Technique

[0002] A fan is a machine that relies on the input mechanical energy to increase the gas pressure and pump the gas. It is a driven fluid machine. Currently, most industrial tail gas treatment fans adopt a direct current type or a centrifugal structure to pump the waste gas into the tail gas treatment equipment for relevant treatment.

[0003] Some existing tail gas treatment fans are prone to ash accumulation on the fan blades when sucking high-temperature dusty gas, which affects the aerodynamic performance of the fan. Therefore, a filter screen is usually installed inside the fan. However, during actual use, when the filter screen becomes blocked, the fan efficiency will be reduced, resulting in unstable tail gas flow velocity and affecting the effect of other equipment in treating tail gas. At the same time, when maintaining and cleaning the filter screen, the machine needs to be shut down, which will affect the continuous operation efficiency of the equipment.

[0004] Therefore, in view of this, research and improvement are carried out on the existing structure and deficiencies, and an efficient tail gas treatment fan is proposed. Summary of the Invention

[0016] The present invention provides an efficient tail gas treatment fan, which has the following beneficial effects:

[0017] 1. During the process of sucking tail gas, the present invention uses a conical filter cover to filter the impurity particles in the waste gas, so that the impurity particles can flow towards the edge of the filter cover, thereby preventing more dust impurities from adhering to the middle of the filter cover. Moreover, the servo motor can be started regularly, and the driving ring can be driven to rotate through the driving gear and the gear ring. The fixed column will drive the synchronous frame to move horizontally under the guidance of the driving groove, so that the retaining ring is separated from the filter cover. At this time, the impurity dust particles will enter the inner side of the inner lining sleeve. At the same time, there is no restriction on the rotation direction of the filter cover. Therefore, when the air flow passes through the inclined guide vane, the filter cover and the inner lining sleeve will be driven to rotate through the connecting sleeve, the adjusting sleeve, the supporting sleeve, the transmission rod and the transmission sleeve, thereby improving the effect of the dust particles flowing outwards by using the centrifugal force. During this process, the filter cover is also easily pushed by the air flow under the action of the spring seat to vibrate, which is beneficial to the falling off of the dust. After cleaning, when the servo motor drives in the reverse direction, similarly, the retaining ring can be pressed against the fixed column to isolate the dust impurities and prevent them from falling back to the middle of the filter cover. At the same time, the connecting sleeve will stop rotating. Therefore, the inclined guide vane can be used to guide the air flow, making the air flow distribution entering the impeller more uniform, which is beneficial to extending the service life and working efficiency of the impeller.

[0018] 2. When the retaining ring loosens the filter cover, the avoidance groove at the lower part of the retaining ring will just be blocked by the two groups of bristles of the brush plate, thus preventing the air flow from entering the dust collection box and preventing the internal dust impurities from being blown out again. At the same time, the inner side of the inner lining sleeve will contact with one group of bristles of the brush plate. Therefore, when the inner lining sleeve rotates, the dust particles inside it can be intercepted. When the driving ring is subsequently controlled to rotate in the reverse direction so that the retaining ring presses the filter cover, as the driving ring continues to rotate, the fixed column will slide in the straight groove of the driving groove. At this time, the rack will contact with the driven gear, and the larger thrust can be used to drive the damping rotating shaft to rotate, so as to sweep the dust impurities intercepted by the brush plate into the dust collection box. And the sealing ring will seal between the air inlet pipe and the retaining ring to reduce the interference of the air flow, so that the impurities can settle to the lower end inside the dust collection box. Therefore, during the cleaning process of the filtering structure, there is no need to stop the machine, which is beneficial to maintaining the continuity during the use of the fan and is more efficient.

[0019] 3. When the angle of the guide vane needs to be adjusted according to requirements in the present invention, only by rotating the worm, the worm gear can drive the adjusting shaft to rotate. At this time, the driving plate will drive the limiting sleeve to move through the driving column, and then the position of the adjusting sleeve outside the driving shaft can be changed. Therefore, when the sliding column slides in the guiding groove, the driving shaft will rotate, and then drive all the guide vanes to rotate simultaneously through the central gear and the planetary gears, which is beneficial to meeting the usage requirements in different situations, improving the adaptation range of the equipment. And during the adjustment process, the adjusting shaft will also drive the scale disk to rotate. Therefore, it is convenient to control the rotation degree of the guide vane externally through the pointer. Brief Description of the Drawings

[0029] Please refer to Figures 1 to 8 As shown in the figure, the present invention provides a technical solution: an efficient exhaust gas treatment fan, including a volute 1 and an intercepting component 5.

The intercepting component 5 is arranged in the middle of the air inlet pipe 2. The intercepting component 5 includes a servo motor 501, a driving gear 502, a gear ring 503, a driving ring 504, a driving groove 505, a fixed column 506, a synchronous frame 507, a retaining ring 508, a filter cover 509, a spring seat 510 and an inner lining sleeve 511. A servo motor 501 is arranged at the lower end of one side of the volute 1, and a driving gear 502 is connected to the end of the servo motor 501. The driving gear 502 meshes with the gear ring 503 at the top, and a driving ring 504 is fixed on one side of the gear ring 503. And the driving ring 504 is rotatably connected to the air inlet pipe 2. A driving groove 505 is formed on the outer side of the driving ring 504, and a fixed column 506 is slidably connected to the inside of the driving groove 505. One end of the fixed column 506 is fixed with a synchronous frame 507, and the synchronous frame 507 is slidably connected to the air inlet pipe 2. One end of the synchronous frame 507 is fixed with a retaining ring 508, and a filter cover 509 is arranged on one side of the retaining ring 508. A spring seat 510 is arranged on one side of the filter cover 509, and an inner lining sleeve 511 is connected to one end of the spring seat 510. And the inner lining sleeve 511 is rotatably connected to the air inlet pipe 2.

[0030] Please refer to Figures 1 to 4, a guiding component 6 is arranged inside the filter cover 509, and the guiding component 6 includes a transmission sleeve 601, a transmission rod 602 and a support sleeve 603. The transmission sleeve 601 is fixed inside the filter cover 509, and the transmission rod 602 is slidably connected to the outer side of one end of the transmission sleeve 601. A support sleeve 603 is sleeved on the outer side of the middle of the transmission rod 602, and the support sleeve 603 is fixedly connected to the inner lining sleeve 511. The guiding component 6 further includes an adjusting sleeve 604, a connecting sleeve 605 and guide vanes 606. The adjusting sleeve 604 is slidably connected to the outer side of one end of the transmission rod 602, and the connecting sleeve 605 is slidably connected to the inside of one end of the adjusting sleeve 604, and the guide vanes 606 are rotatably connected to the outer side of the connecting sleeve 605;

[0031] The specific operation is as follows. Start the driving motor 3 to drive the impeller 4 to rotate, and the exhaust gas can be sucked. When the exhaust gas enters the inside of the air inlet pipe 2, the filter cover 509 can be used to filter the impurity particles in the waste gas. Since the filter cover 509 is conical, it has a certain guiding effect on the air flow, so that the impurity particles can flow towards the edge of the filter cover 509, thereby preventing more dust impurities from adhering to the middle of the filter cover 509, which is beneficial to improving the overall dirt capacity of the filter cover 509. And the servo motor 501 can be started regularly, and the driving ring 504 can be driven to rotate through the driving gear 502 and the gear ring 503. The fixed column 506 will drive the synchronous frame 507 to move horizontally under the guidance of the driving groove 505, so that the retaining ring 508 is separated from the filter cover 509. At this time, the impurity dust particles will enter the inside of the inner lining sleeve 511. At the same time, the filter cover 509 will not be restricted in the rotation direction. Therefore, when the air flow passes through the inclined guide vanes 606, the filter cover 509 and the inner lining sleeve 511 will also be driven to rotate through the connecting sleeve 605, the adjusting sleeve 604, the support sleeve 603, the transmission rod 602 and the transmission sleeve 601, so as to improve the effect of the dust particles flowing outwards by using the centrifugal force. During this process, since the filter cover 509 and the inner lining sleeve 511 are elastically connected through the spring seat 510, the filter cover 509 is also easily pushed by the air flow to vibrate, which is beneficial to the dust falling off, can reduce the dust adhesion in the middle of the filter cover 509, avoid blockage and affect the efficiency of the fan. And after cleaning, when the servo motor 501 is driven in the reverse direction, similarly, the retaining ring 508 can be pressed against the fixed column 506 to isolate the dust impurities and prevent them from falling back to the middle of the filter cover 509. At the same time, the connecting sleeve 605 will also stop rotating. Therefore, the inclined guide vanes 606 can be used to guide the air flow, so that the air flow entering the impeller 4 is more evenly distributed, which is beneficial to extending the service life and working efficiency of the impeller 4.

[0032] Please refer to Figures 4 to 8, a cleaning assembly 7 is provided at the lower part of the air inlet pipe 2. The cleaning assembly 7 includes a sealing ring 701 and an avoidance groove 702. A sealing ring 701 is fixed to one side of the retaining ring 508, and the sealing ring 701 is slidably connected to the air inlet pipe 2. An avoidance groove 702 is formed at the lower end of the sealing ring 701. The cleaning assembly 7 further includes a rack 703, a driven gear 704, a damping rotating shaft 705 and a brush plate 706. A rack 703 is fixed to the lower end of one side of the driving ring 504, and a driven gear 704 is engaged with one side of the rack 703. A damping rotating shaft 705 is fixed to the upper part of the driven gear 704, and the damping rotating shaft 705 is rotatably connected to the air inlet pipe 2. A brush plate 706 is arranged at the upper end of the damping rotating shaft 705, and the brush plate 706 is cross-shaped. The cleaning assembly 7 further includes a dust collection box 707 and a convex plate 708. The dust collection box 707 is fixed to the lower part of the air inlet pipe 2, and the dust collection box 707 is communicated with the inside of the air inlet pipe 2. A convex plate 708 is arranged inside the dust collection box 707. An adjusting assembly 8 is connected to the top of one end of the air inlet pipe 2. The adjusting assembly 8 includes a worm 801, a worm gear 802 and an adjusting shaft 803. The worm 801 is rotatably connected above one end of the air inlet pipe 2, and a worm gear 802 is engaged with one side of the worm 801. An adjusting shaft 803 is fixed inside the worm gear 802. The adjusting assembly 8 further includes a scale disk 804 and a pointer 805. The scale disk 804 is arranged at the upper end of the adjusting shaft 803, and a pointer 805 is slidably connected to the top of the scale disk 804, and the pointer 805 is fixed to the air inlet pipe 2. The adjusting assembly 8 further includes a driving plate 806, a driving column 807 and a limiting sleeve 808. The driving plate 806 is fixed to the bottom of the adjusting shaft 803, and the driving column 807 is slidably connected to the inside of the driving plate 806. The limiting sleeve 808 is fixed to the bottom of the driving column 807, and the limiting sleeve 808 is rotatably connected to the adjusting sleeve 604. The adjusting assembly 8 further includes a sliding column 809, a driving shaft 810, a guiding groove 811, a central gear 812 and a planetary gear 813. The sliding column 809 is fixed to the inner side of the adjusting sleeve 604, and a driving shaft 810 is arranged on the inner side of the adjusting sleeve 604. A guiding groove 811 is formed on the outer side of the driving shaft 810. A central gear 812 is fixed to one end of the driving shaft 810, and a planetary gear 813 is engaged with the outer side of the central gear 812, and the planetary gear 813 is fixed to the guide vane 606;

[0033] The specific operation is as follows. Before use, first rotate the worm 801, which can make the worm wheel 802 drive the adjusting shaft 803 to rotate. At this time, the driving plate 806 will drive the limiting sleeve 808 to move through the driving column 807, and the position of the adjusting sleeve 604 outside the driving shaft 810 can be changed. Therefore, when the sliding column 809 slides in the guiding groove 811, the driving shaft 810 will rotate, and then drive all the guide vanes 606 to rotate simultaneously through the central gear 812 and the planetary gear 813, which is beneficial to meeting the use requirements in different situations and improving the adaptation range of the equipment. And during the adjustment process, the adjusting shaft 803 will also drive the dial 804 to rotate. Therefore, it is convenient to control the rotation degree of the guide vane 606 externally through the pointer 805. And by using the deceleration and self-locking performance of the worm 801 and the worm wheel 802, it is convenient to perform fine-tuning operations and enhance the stability after adjustment. During use, when the retaining ring 508 loosens the filter cover 509, the avoidance groove 702 at the lower part of the retaining ring 508 will just be blocked by the two groups of bristles of the brush plate 706, thus preventing air flow from entering the inside of the dust collection box 707 and preventing the dust and impurities inside the dust collection box 707 from being blown out again. And when the inner lining sleeve 511 rotates, one side of it will contact the bristles on one side of the brush plate 706, which can intercept the dust particles inside the inner lining sleeve 511. At the same time, due to the large frictional resistance between the damping rotating shaft 705 and the air inlet pipe 2, it will not rotate. And when the driving ring 504 is subsequently controlled to rotate in the reverse direction so that the retaining ring 508 presses the filter cover 509 tightly, as the driving ring 504 continues to rotate, the fixed column 506 will slide in the straight groove of the driving groove 505. At this time, the rack 703 will contact the driven gear 704, and a large thrust can be used to drive the damping rotating shaft 705 to rotate, so as to sweep the dust and impurities intercepted by the brush plate 706 into the dust collection box 707. At the same time, the sealing ring 701 will seal between the air inlet pipe 2 and the retaining ring 508 to reduce the interference of air flow, so that the impurities can settle to the lower end inside the dust collection box 707. And during the rotation of the brush plate 706, its bristles will contact the convex plate 708 and flap, thus improving the effect of dust desorption on the bristles. Therefore, during the cleaning process of the filtering structure, there is no need to stop the machine, which is beneficial to maintaining the continuity during the use of the fan and is more efficient.

[0034] In summary, for this efficient tail gas treatment fan, when in use, first rotate the worm 801 according to requirements, so that the worm wheel 802 drives the adjusting shaft 803 to rotate. At this time, the driving plate 806 will drive the limit sleeve 808 to move through the driving column 807, and the position of the adjusting sleeve 604 outside the driving shaft 810 can be changed. Therefore, when the sliding column 809 slides in the guiding groove 811, the driving shaft 810 will rotate, and then drive all the guide vanes 606 to rotate simultaneously through the central gear 812 and the planetary gear 813. At the same time, the adjusting shaft 803 will also drive the dial 804 to rotate. Therefore, it is convenient to control the rotation degree of the guide vane 606 externally through the pointer 805. Secondly, after docking the air inlet pipe 2 with the external tail gas treatment equipment, start the driving motor 3 to drive the impeller 4 to rotate, and the tail gas can be sucked. Then, the tail gas will enter the interior of the air inlet pipe 2. At this time, the filter cover 509 can be used to filter the impurity particles in the waste gas. Since the filter cover 509 is conical, the impurity particles can flow towards the edge of the filter cover 509. After that, after using for a period of time, start the servo motor 501, and the driving ring 504 can be driven to rotate through the driving gear 502 and the gear ring 503. The fixed column 506 will drive the synchronous frame 507 to move horizontally under the guidance of the driving groove 505, so that the retaining ring 508 is separated from the filter cover 509. At this time, the impurity dust particles will enter the inner side of the inner lining sleeve 511. In addition, when the retaining ring 508 releases the filter cover 509, the avoidance groove 702 at the lower part of the retaining ring 508 will just be blocked by the two groups of bristles of the brush plate 706, so as to prevent air flow from entering the dust collection box 707. Then, when the air flow passes through the inclined guide vane 606, it will also drive the filter cover 509 and the inner lining sleeve 511 to rotate through the connecting sleeve 605, the adjusting sleeve 604, the support sleeve 603, the transmission rod 602 and the transmission sleeve 601, so as to improve the effect of the dust particles flowing outwards by centrifugal force. During this process, the filter cover 509 is also easily pushed by the air flow under the action of the spring seat 510 to vibrate. And when the inner lining sleeve 511 rotates, one side of it will contact the bristles on one side of the brush plate 706, and the dust particles inside the inner lining sleeve 511 can be intercepted. Finally, the driving ring 504 is rotated in the reverse direction by the servo motor 501. Similarly, the retaining ring 508 can be used to press the filter cover 509 tightly to isolate the dust impurities and prevent them from falling back to the middle of the filter cover 509. At the same time, the connecting sleeve 605 will also stop rotating. Therefore, the inclined guide vane 606 can be used to guide the air flow, so that the air flow entering the impeller 4 is more evenly distributed. And as the driving ring 504 continues to rotate, the fixed column 506 will slide in the straight groove of the driving groove 505. At this time, the rack 703 will contact the driven gear 704, and the relatively large thrust can be used to drive the damping rotating shaft 705 to rotate, so as to sweep the dust impurities intercepted by the brush plate 706 into the dust collection box 707. At the same time, the sealing ring 701 will seal between the air inlet pipe 2 and the retaining ring 508.Reduce the interference of the air flow so that impurities settle to the lower end inside the dust collection box 707. During the rotation of the brush plate 706, its bristles will contact the convex plate 708 and flutter, thereby improving the effect when dust is desorbed from the bristles.
