Description

TECHNICAL FIELD

[0001] The application belongs to the technical field of screen production equipment, and more particularly to a self-cleaning cloth bag dust collector. BACKGROUND

[0002] The cloth bag dust collector is widely used in the field of industrial waste gas treatment due to its high dust removal performance. Its working principle is mainly to intercept and filter the dust in the waste gas through the cloth bag, so as to realize gas-solid separation and achieve the purpose of purifying air. However, the cloth bag dust collector in the prior art has obvious defects in actual use. As the dust removal work continues, a large amount of dust will adhere to the surface of the cloth bag, resulting in a decrease in filtration efficiency, at which time the cloth bag needs to be cleaned.

[0003] However, the traditional cloth bag dust collector often needs to pause the equipment operation during cleaning, which not only affects the production progress and reduces the work efficiency, but also increases the production cost. In addition, the cleaning of the existing cloth bag dust collector usually relies on external driving facilities such as compressed air devices, which not only increases the purchase cost and maintenance cost of the equipment, but also has the risk of failure of the external driving facilities leading to abnormal cleaning.

[0024] The self-cleaning bag filter provided in this application will now be described.

[0025] Please refer to the following: Figures 1 to 12 A self-cleaning baghouse dust collector includes a housing 1, a dust collection mechanism 2, a drive fan 3, an energy storage mechanism 4, and a linkage mechanism 5. The housing 1 is internally divided into an inlet chamber and a filter chamber. An inlet pipe 101 is connected to the inlet chamber, and an exhaust pipe 102 is connected to the filter chamber. A dust collection bin 103 is located at the bottom of the housing 1. The dust collection mechanism 2 is slidably arranged within the filter chamber and has multiple filter bags 201, allowing exhaust gas to enter the filter bags 201 through the inlet chamber for filtration before being discharged from the filter chamber. The drive fan 3 is rotatably mounted between the inlet pipe 101 and the inlet chamber. The connection is designed so that the incoming exhaust gas can drive the drive fan 3 to rotate; the energy storage mechanism 4 is located between the housing 1 and the dust removal mechanism 2. When the external force drives the dust removal mechanism 2 to slide, the energy storage mechanism 4 stores energy. When the external force is removed, the energy storage mechanism 4 releases energy and drives the dust removal mechanism 2 to reset; the linkage mechanism 5 is located between the drive fan 3 and the dust removal mechanism 2, so that the drive fan 3 can drive the dust removal mechanism 2 to slide. When it turns through a preset angle, the drive fan 3 instantly releases the drive of the dust removal mechanism 2, and the energy storage mechanism 4 drives the dust removal mechanism 2 to reset, so as to form a vibration cleaning of the filter bag 201.

[0026] The beneficial effects of the self-cleaning bag filter provided in this embodiment are as follows: Compared with the prior art, the self-cleaning bag filter provided in this embodiment utilizes the exhaust gas entering the inlet pipe 101 to drive the drive fan 3 to rotate, which in turn drives the dust removal mechanism 2 to slide through the linkage mechanism 5. Unlike traditional bag filter 201 dust collectors, it does not rely on external compressed air devices or other driving facilities, reducing the purchase and maintenance costs of the equipment and avoiding the risk of cleaning failure due to the failure of external driving facilities. The drive fan 3 drives the dust removal mechanism 2 to slide, and when it rotates through a preset angle, the drive on the dust removal mechanism 2 is instantly released. At this time, the energy storage mechanism 4 releases energy and drives the dust removal mechanism 2 to reset, forming a vibration cleaning of the filter bag 201. This self-cleaning method does not require stopping the equipment operation, does not affect the production progress, improves work efficiency, and also reduces the additional energy consumption and equipment wear caused by equipment start-up and shutdown. The overall structure includes a shell 1, a dust removal mechanism 2, a drive fan 3, an energy storage mechanism 4, and a linkage mechanism 5. The components cooperate with each other to achieve the self-cleaning function. The structure is relatively simple and compact, and easy to install and maintain.

[0027] like Figure 5 and Figure 6 As shown, the dust removal mechanism 2 includes two dust removal plates 202, multiple dust removal holes 203, multiple filter bags 201, and a sealing plate 204. The two dust removal plates 202 are arranged vertically at intervals, slidably within the filter chamber, and are sealed to the inner wall of the filter chamber. Multiple dust removal holes 203 are evenly distributed on the dust removal plates 202. Each filter bag 201 corresponds to two dust removal holes 203, with both ends of the filter bag 201 fixed to the two dust removal plates 202, and the filter bag 201 is in communication with the corresponding dust removal hole 203. The sealing plate 204 is slidably disposed on the lower dust removal plate 202, and is used to block or unblock the dust removal holes 203 of the lower dust removal plate 202. A handle 205 is provided on the side wall of the sealing plate 204 for easy manual insertion or removal.

[0028] Two dust collector plates 202 are arranged vertically at intervals and sealed with the inner wall of the filter chamber, effectively preventing unfiltered exhaust gas from leaking through the gap between the dust collector plates 202 and the inner wall of the filter chamber, thus ensuring the dust removal effect. The two ends of the filter bag 201 are fixed to the dust removal holes 203 of the two dust collector plates 202 respectively. This installation method makes the installation and replacement of the filter bag 201 more convenient and easier to maintain.

[0029] The lower dust collector plate 202 is equipped with a sealing plate 204. The sealing plate 204 can block or unblock the dust collection holes 203 of the lower dust collector plate 202. By controlling the state of the sealing plate 204, the ventilation state of the filter bag 201 can be controlled. When the filter bag 201 dust collector is in normal use, the sealing plate 204 is inserted to block the dust collection holes 203. Exhaust gas can only enter the filter chamber through the filter bag 201 and finally be discharged, so as to facilitate the filtration of exhaust gas. After a period of use, the sealing plate 204 is pulled out, allowing the dust in the filter bag 201 to fall into the dust collection bin 103 below, preventing dust from clogging the filter bag 201. Opening the sealing plate 204 to allow the dust in the filter bag 201 to fall is a very fast process, and the dust collector can be used without stopping the operation.

[0030] like Figure 1 , Figure 2 and Figure 7 As shown, the lower dust removal plate 202 has slots 206, which pass through the dust removal holes 203. A sealing plate 204 is inserted into the slots 206. This structure allows for smoother installation and sliding of the sealing plate 204, facilitating operation and control. The slots 206 passing through the dust removal holes 203 ensure accurate alignment of the sealing plate 204 with the holes during insertion and removal, effectively sealing and releasing the dust removal holes 203.

[0031] In this embodiment, along the insertion direction of the sealing plate 204, a dust discharge groove 207 is provided on the downstream side of the slot 206. The opening of the dust discharge groove 207 is located on the bottom surface of the dust removal plate 202 below, and the dust discharge groove 207 is connected to the slot 206.

[0032] When the sealing plate 204 is pulled out, the dust attached to the cloth bag 201 falls off and enters the dust collection chamber 103 below through the dust removal hole 203 on the dust removal plate 202. Inevitably, some dust will enter the slot 206. When the sealing plate 204 is inserted, it will push the dust in the slot 206 towards the dust discharge groove 207, and then discharge it into the dust collection chamber 103 through the dust discharge groove 207, so that the dust can be discharged smoothly and the operating stability of the equipment is improved.

[0033] like Figure 1 and Figure 3As shown, the housing 1 has two sliding grooves, each corresponding to a dust removal plate 202. The dust removal plate 202 is inserted into the corresponding sliding groove, with both ends extending to the outside of the housing 1. One end of the upper dust removal plate 202 is equipped with an anti-detachment plate 208. The long axis of the anti-detachment plate 208 is longer than the long axis of the sliding groove. When the energy storage mechanism 4 is in its natural state, the anti-detachment plate 208 near both ends abuts against the outer wall of the housing 1. This prevents the dust removal plate 202 from detaching from the sliding groove during sliding, ensuring the normal operation of the dust removal mechanism 2.

[0034] The dust collector plate 202 extends to the outside of the housing 1 at both ends. The dust collector plate 202 keeps the slide groove blocked during the sliding process to prevent the exhaust gas from leaking out of the slide groove without being filtered, thereby improving the overall sealing performance of the bag filter 201 dust collector.

[0035] like Figure 3 and Figure 4 As shown, the energy storage mechanism 4 includes a horizontal energy storage plate 401, a vertical energy storage plate 402, multiple springs 403, and a connecting member 404. The horizontal energy storage plate 401 is arranged horizontally, and one side of the horizontal energy storage plate 401 is fixed to the housing 1. The vertical energy storage plate 402 is fixed to the top of the horizontal energy storage plate 401. The multiple springs 403 are arranged in parallel, and one end of each spring 403 is fixed to the vertical energy storage plate 402. One end of the connecting member 404 is connected to the spring 403, and the other end is detachably connected to the dust removal plate 202.

[0036] The energy storage mechanism 4 includes a horizontal energy storage plate 401, a vertical energy storage plate 402, a spring 403, and a connector 404. Its structure is simple. The spring 403, as an energy storage element, can stably store and release energy, providing power for the reset of the dust removal mechanism 2 and ensuring the effectiveness of vibration cleaning. One end of the connector 404 is connected to the spring 403, and the other end is detachably connected to the dust removal plate 202. When the spring 403 or other components malfunction, disassembly and replacement are convenient, reducing maintenance costs and difficulty.

[0037] In this embodiment, when the spring 403 is in its natural state, the anti-detachment plate 208 abuts against the outer wall of the housing 1, so that the dust removal plate 202 is continuously subjected to the tension of the spring 403 during the reset process, until the anti-detachment plate 208 finally impacts the housing 1, forming the vibration of the dust removal mechanism 2, so as to vibrate the filter bag 201 to remove dust.

[0038] Combination Figure 5 , Figure 8 , Figure 9 , Figure 10 , Figure 11 and Figure 12The linkage mechanism 5 shown includes a drive half-wheel 501, a drive rod 502, and a drive block 503. The drive half-wheel 501 is connected to the drive fan 3, which drives the drive half-wheel 501 to rotate. The bottom end of the drive rod 502 is fixed to the upper dust collector plate 202. Along the axial direction of the drive half-wheel 501, the drive rod 502 is located on one side of the drive half-wheel 501; and along the radial direction of the drive half-wheel 501, the drive rod 502 is located on one side of the drive half-wheel 501. The drive block 503 is located at the top end of the drive rod 502. Along the axial direction of the drive half-wheel 501, the drive half-wheel 501 and the drive block 503 are arranged side by side. When the planar sidewall of the drive half-wheel 501 is arranged horizontally, the horizontal sidewall of the drive half-wheel 501 is flush with the bottom surface of the drive block 503, so that the drive half-wheel 501 can push the drive block 503 away from the rotation axis of the drive half-wheel 501 due to rotation. When the planar sidewall of the drive half-wheel 501 is arranged horizontally and the drive half-wheel 501 is located below the planar sidewall, the drive half-wheel 501 instantly removes its pushing force on the drive block 503.

[0039] Through the special structure of the drive half-wheel 501, the drive on the dust removal mechanism 2 can be instantly released when it turns through a preset angle, so that the energy storage mechanism 4 can drive the dust removal mechanism 2 to reset in time, realizing vibration cleaning of the filter bag 201. This design makes the cleaning process more precise and effective.

[0040] The linkage mechanism 5 has a relatively simple structure. Through the cooperation of the drive half wheel 501 and the drive block 503, as well as the transmission of the drive rod 502, it can stably realize the power transmission and control between the drive fan 3 and the dust removal mechanism 2, with high reliability.

[0041] In actual use, with the bottom end face of the drive block 503 as the unlocking surface, when a portion of the drive half-wheel 501 is above the unlocking surface, rotation pushes the drive block 503 to slide, thereby causing the dust removal plate 202 to slide. After passing through... Figure 8 , Figure 9 and Figure 10 After the pushing process, when the drive half wheel 501 is completely below the unlocking surface, the drive half wheel 501 releases its push on the drive block 503, and the drive block 503 resets under the action of the aforementioned spring 403.

[0042] like Figure 5As shown, a first rotating shaft 504 is rotatably mounted inside the air intake chamber. A drive fan 3 is mounted on the first rotating shaft 504 and is used to drive the first rotating shaft 504 to rotate. A first gear 505 is fixedly mounted on the first rotating shaft 504. A second rotating shaft 506 is provided on one side of the first rotating shaft 504. A second gear 507 and a third gear 508 are fixedly mounted on the second rotating shaft 506. The second gear 507 meshes with the first gear 505. A third rotating shaft 509 is provided on one side of the second rotating shaft 506. A fourth gear 510 is provided on the third rotating shaft 509 and meshes with the third gear 508. The diameter of the first gear 505 is smaller than the diameter of the second gear 507, and the diameter of the third gear 508 is smaller than the diameter of the fourth gear 510. A drive half-wheel 501 is fixed on the third rotating shaft 509, and the axis of the drive half-wheel 501 is not on the same straight line as the axis of the third rotating shaft 509.

[0043] By setting up a first rotating shaft 504, a second rotating shaft 506, and a third rotating shaft 509, along with corresponding gear transmissions, where the diameter of the first gear 505 is smaller than the diameter of the second gear 507, and the diameter of the third gear 508 is smaller than the diameter of the fourth gear 510, a speed reduction transmission is achieved, allowing the drive half-wheel 501 to rotate at a lower speed. Since the dust collector bag does not need to continuously vibrate for dust removal, the low speed increases the time between two vibrations, which is also the time for dust to accumulate inside the filter bag 201.

[0044] Furthermore, the above design allows the drive fan 3 to be driven by a relatively low external driving force, which here is the blowing force of the exhaust gas on the drive fan 3. The engagement of each shaft and gear forms a structure similar to the effort-saving gears in a multi-speed bicycle.

[0045] Moreover, the gear transmission mechanism has a compact structure, occupies little space, and can be reasonably arranged within the limited air intake chamber without affecting the normal operation of other components.

[0046] As a preferred technical solution, a protective box 511 is provided inside the air intake chamber. The protective box 511 covers the first gear 505, the second gear 507, the third gear 508, and the fourth gear 510, which can prevent dust and other impurities from entering the gear transmission mechanism, avoid wear and damage to the gears, ensure the accuracy and stability of the gear transmission, and thus extend the service life of the equipment. Finally, a settling box 105 is provided on one side of the air inlet chamber. The air inlet end of the air inlet pipe 101 is connected to the settling box 105, and the settling box 105 is connected to the external exhaust pipe 104. Along the gas flow direction, the cross-sectional area of ​​the settling box 105 is larger than the cross-sectional area of ​​the inner cavity of the exhaust pipe 104. A detachable drain plate 106 is provided at the bottom of the settling box 105. When the drain plate 106 is removed, the bottom of the settling box 105 can be opened, allowing large dust particles in the exhaust gas to settle in the settling box 105 due to the reduced flow velocity, thus playing a pre-settling role, reducing the filtration burden on the filter bag 201, and improving the service life and dust removal efficiency of the filter bag 201. In this embodiment, the drain plate 106 can be fixed by bolts or other suitable detachable structures.

[0047] The bottom of the dust collection bin 103 is equipped with a slide valve 107, which facilitates the control of dust emission from the dust collection bin 103 and the centralized treatment of dust.

[0048] The above are merely preferred embodiments of this application and are not intended to limit this application. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this application should be included within the protection scope of this application.
