Description

Technical Field

[0001] This invention relates to the field of dust collector technology, and more particularly to a baghouse multifunctional dust collector. Background Technology

[0002] Baghouse dust collectors are currently the most widely used dust removal equipment, typically used to treat exhaust gas containing dust. They remove dust from the exhaust gas by intercepting it through filter bags. Then, the filter bags are periodically cleaned by short bursts of compressed air injected into them to maintain their air permeability.

[0003] However, when existing baghouse dust collectors perform back-blowing cleaning of the filter bags, the air jet is located at the top of the filter bag, resulting in the airflow being far from the bottom of the filter bag. This reduces the cleaning effect of the airflow reaching the bottom of the filter bag. Furthermore, some dust adheres to the inner wall of the dust collector during back-blowing, making it easy for dust on the inner wall to be drawn to the outside of the filter bag when the exhaust gas is subsequently cleaned.

[0004] Furthermore, when the installation location of the dust collector is limited, pleated filter bags are used to increase the filtration area within the same volume. However, during back-flushing cleaning of the filter bags, due to the multiple pleated layers on the filter bags, some of the inner pleated layers may be squeezed and stacked by the airflow, causing the outer pleated layers to be squeezed and stacked, resulting in dust being trapped in the outer pleated layers and unable to be blown off by the airflow. Summary of the Invention

[0005] In order to overcome the shortcomings of existing baghouse dust collectors, such as the low cleaning effect of the airflow from the jet nozzle on the lower side of the filter bag during back-blowing cleaning, and the fact that some dust will adhere to the inner wall of the dust collector during back-blowing, making it easy for dust on the inner wall to be sucked onto the filter bag, this invention provides a multi-functional baghouse dust collector.

[0006] Technical Solution: A baghouse-type multi-functional dust collector includes a housing and a partition plate; an air inlet pipe is provided on the housing; an exhaust pipe is provided on the housing; a partition plate is fixedly connected to the inside of the housing, dividing the housing into upper and lower spaces, with the exhaust pipe located above and below the partition plate; a waste discharge port is provided on the housing; it also includes fixed cylinders, a cleaning plate, sponge strips, a lifting assembly, a filter assembly, and a cleaning assembly; several fixed cylinders are fixedly connected to the partition plate, and the fixed cylinders penetrate the partition plate; each fixed cylinder is connected to a filter assembly for filtering dust; a lifting assembly is connected to the inside of the housing; the lifting assembly is connected to the cleaning plate, and the lifting assembly is used to move the cleaning plate up and down; a sponge strip is fixedly connected to the cleaning plate, and the sponge strip is in contact with the inner wall of the housing; a cleaning assembly for cleaning is connected to the cleaning plate.

[0007] To further explain, the filter assembly includes cleaning rings and pleated filter bags; a pleated filter bag for filtering dust is fixedly attached to the lower side of the fixed cylinder; several cleaning rings are connected to the pleated filter bag; the cleaning rings penetrate the pleated filter bag.

[0008] Further explanation: The cleaning assembly includes nozzles, air blowers, and air pipes; several nozzles are fixedly connected to the lower side of each cleaning ring; an air vent is provided inside each cleaning ring; an air inlet is provided on the outer side of each cleaning ring, and the air vent connects to the air inlet; an air blower is provided inside each cleaning ring, and the nozzle connects to the air blower; a connecting channel is provided inside each cleaning ring, and the air vent connects to the air blower through the connecting channel; several air blowers are fixedly connected to the upper side of the cleaning plate; two air outlets are provided on the left side of each air blower; an air pipe is fixedly connected to the housing, the air pipe passes through the partition plate, all air blowers are interconnected through the air pipe, and the air pipe connects to an external compressed air tank.

[0009] Further explanation: It also includes a cleaning sponge; the cleaning plate is provided with several through grooves, the pleated filter bag is located in the through grooves of the cleaning plate, and a cleaning sponge is fixed to the inside of each through groove; the cleaning sponge is annular, and several protrusions are provided on its inner side; the protrusions are located in the pleats of the pleated filter bag, and the inner side of the cleaning sponge is tightly attached to the outer side of the pleated filter bag.

[0010] To further explain, it also includes support strips; several support strips arranged in a ring array are fixed to the lower side of each cleaning ring, and the support strips are located inside the pleated filter bag.

[0011] To further explain, it also includes an annular airbag; an annular airbag is fixedly attached to the inner side of each cleaning ring, the inner side of the annular airbag is the telescopic end, and the annular airbag is connected to the ventilation groove of the cleaning ring.

[0012] To further explain, it also includes a sealing block and an elastic element; a sealing block is slidably connected in each connecting channel; and an elastic element is fixedly connected to the inner wall of each sealing block and the connecting channel.

[0013] To further explain, it also includes a locking block; a locking block is fixed to the outside of each air inlet; the locking block is provided with a through groove, and four rubber strips are provided on the inner wall of the through groove.

[0014] To further explain, an airflow velocity sensor is installed inside the chamber, located on the upper side of the partition plate.

[0015] To further explain, the cleaning sponge has bristles on the side near the pleated filter bag.

[0016] The beneficial effects of this invention are as follows: When it is necessary to clean the dust adhering to the outside of the pleated filter bag, the invention enables the air blowing port to sequentially align with the air inlets of the three cleaning rings on the pleated filter bag. Each time the air is aligned, the solenoid valve at the connection between the compressed air tank and the air pipe is opened, allowing the airflow to sequentially pass through the air pipe, air blowing port, air inlet, air vent, connecting channel, and air blowing vent before being sprayed downwards from the nozzle. This blows and cleans the area of ​​the pleated filter bag located below the cleaning rings, removing the dust adhering to the outside of the pleated filter bag. Furthermore, the pleated filter bag is blown in sections, thereby achieving uniform dust removal and effectively ensuring the overall back-blowing dust removal effect of the pleated filter bag.

[0017] When back-blowing and cleaning the pleated filter bags with high-pressure airflow, the cleaning plate and cleaning sponge intercept the blown-off dust to prevent dust from adhering to the cleaned area of ​​the pleated filter bags. During back-blowing, the pleats of the pleated filter bags are fixed together by the cooperation of protrusions and support strips to prevent the pleats from being squeezed and stacked by the airflow, which would cause the dust to be trapped in the outer folds and unable to be blown off by the airflow. This effectively ensures the cleaning effect of the pleated filter bags.

[0018] As the cleaning plate moves downwards, it drives the cleaning sponge to wipe the inner wall of the chamber, removing the dust adhering to the inner wall. This prevents the dust from being drawn back onto the outside of the pleated filter bag during subsequent dust removal of the exhaust gas. Attached Figure Description

[0032] The lifting assembly includes a slide rail 301 and an electric slider 302; two slide rails 301 are vertically bolted inside the housing 1; an electric slider 302 is slidably connected to each slide rail 301, and the two electric sliders 302 are fixedly connected to the cleaning plate 303.

[0033] It also includes a cleaning sponge 304; the cleaning plate 303 is provided with six through slots, the pleated filter bag 5 is located in the through slots of the cleaning plate 303, and a cleaning sponge 304 is fixedly attached to the inside of each through slot; the cleaning sponge 304 is annular, and several protrusions 30401 are provided on its inner side; the protrusions 30401 are located in the pleated recesses of the pleated filter bag 5, and the inner side of the cleaning sponge 304 is tightly attached to the outer side of the pleated filter bag 5.

[0034] It also includes support bars 6; several support bars 6 arranged in a ring array are fixed to the lower side of each cleaning ring 4, and the support bars 6 are located inside the pleated filter bag 5.

[0035] It also includes an annular airbag 202; an annular airbag 202 is fixedly attached to the inner side of each cleaning ring 4, the inner side of the annular airbag 202 is the telescopic end, and the annular airbag 202 is connected to the ventilation groove 4001 of the cleaning ring 4.

[0036] It also includes a blocking block 101 and an elastic element 102; a blocking block 101 is slidably connected in each connecting channel 4003; an elastic element 102 is fixedly connected to the inner wall of each blocking block 101 and the connecting channel 4003, and the elastic element 102 is a spring.

[0037] It also includes a locking block 103; a locking block 103 is fixedly attached to the outside of each air inlet 4002; the locking block 103 is provided with a through groove, and four rubber strips 10301 are provided on the inner wall of the through groove. When the air blowing port 30501 is aligned with the air inlet 4002, the air blowing port 30501 is located in the through groove of the locking block 103, thereby enhancing the sealing of the connection between the air blowing port 30501 and the air inlet 4002 through the rubber strips 10301.

[0038] An airflow velocity sensor is installed inside the housing 1, and the airflow velocity sensor is located on the upper side of the partition plate 2.

[0039] like Figure 1 As shown, with the side where the exhaust pipe 1002 is located as the right side, during operation, the external air extraction device is connected to the exhaust pipe 1002, and the air inlet pipe 1001 is connected to the pipeline that transports dusty exhaust gas. Then, the external air extraction device is controlled to draw air from the exhaust pipe 1002 into the inside of the housing 1, creating a negative pressure inside the housing 1. This draws the exhaust gas from the air inlet pipe 1001 into the housing 1. After entering the housing 1, the exhaust gas passes through the pleated filter bag 5 and enters the inside of the pleated filter bag 5, whereby the dust particles in the exhaust gas are intercepted to the outside of the pleated filter bag 5. The filtered gas flows upward from the middle of the pleated filter bag 5 to the upper side of the partition plate 2, and is finally drawn away by the exhaust pipe 1002. During this process, the pleated filter bag 5 is supported by the support strip 6 to prevent the pleated filter bag 5 from being pulled by the exhaust pipe 1002 and collapsing, which would affect its air permeability.

[0040] And at this time, as Figure 2 As shown, the cleaning plate 303 is located on the upper side of the pleated filter bag 5 to prevent the cleaning plate 303 from obstructing the contact between the exhaust gas and the pleated filter bag 5. At this time, the air blowing port 30501 is aligned with the air inlet 4002 located on the uppermost cleaning ring 4. After working for a period of time, when the airflow velocity sensor in the housing 1 detects that the airflow velocity through the pleated filter bag 5 has decreased significantly, that is, when a lot of impurities are adhered to the outer surface of the pleated filter bag 5 and the dust adhering to the pleated filter bag 5 needs to be cleaned, the air inlet pipe 1001 and the exhaust pipe 1002 are closed, and then the compressed air tank and the ventilation pipe 3 are controlled. The solenoid valve at the 06 connection point opens, allowing high-pressure airflow to enter the air blowing cylinder 305 through the air pipe 306, and then be injected into the air inlet 4002 from the air blowing port 30501. The airflow passes through the air vent 4001, the connecting channel 4003 and the air blowing channel 4004 in sequence, and then sprays downward from the nozzle 201. The airflow sprayed downward from the nozzle 201 blows the inside of the pleated filter bag 5, thereby achieving a back-blowing effect on the pleated filter bag 5, blowing off the dust adhering to the outside of the pleated filter bag 5. The blown-off dust then falls downward and is discharged into the dust collection device from the waste discharge port 1003.

[0041] When back-flushing the pleated filter bag 5, the airflow is far from the lower side of the pleated filter bag 5, resulting in a low cleaning effect on the lower side of the pleated filter bag 5. To ensure the overall back-flushing cleaning effect on the pleated filter bag 5, the electric slider 302 is controlled to move the cleaning plate 303 and its connected parts downwards until the air blowing port 30501 is in contact with the air inlet 4002 located in the middle cleaning ring 4. Then, the solenoid valve at the connection between the compressed air tank and the air pipe 306 is opened, allowing high-pressure airflow to be injected from the air blowing port 30501 into the corresponding air inlet 4002, and the airflow to be ejected downwards from the corresponding nozzle 201. This allows for the blowing and cleaning of the area of ​​the pleated filter bag 5 located below the cleaning ring 4. Then, the electric slider 302 is controlled to drive the cleaning plate 303 and its connected parts to continue moving downwards until the air outlet 30501 is in contact with the air inlet 4002 located on the lower cleaning ring 4. The above steps are then repeated. The solenoid valve at the connection between the compressed air tank and the air pipe 306 is opened, so that the airflow ejected from the nozzle 201 can blow and clean the area of ​​the pleated filter bag 5 located below the cleaning ring 4. This achieves the segmented blowing of the pleated filter bag 5, thereby achieving uniform cleaning of the pleated filter bag 5 and effectively ensuring the overall back-blowing cleaning effect of the pleated filter bag 5.

[0042] Furthermore, when the pleated filter bag 5 is back-blown and cleaned by high-pressure airflow, a large amount of dust will be blown up. Therefore, the cleaning plate 303 intercepts the blown-away dust to prevent dust from adhering to the cleaned area of ​​the pleated filter bag 5. Furthermore, during the back-blowing and cleaning of the pleated filter bag 5, since there are multiple pleated layers on the pleated filter bag 5, some of the inner pleated layers may be squeezed and stacked by the airflow, causing the outer pleated layers of the pleated filter bag 5 to be squeezed and stacked, resulting in dust being trapped in the outer pleated layers and unable to be blown off by the airflow. Therefore, during back-blowing, the protrusion 30401 and the support strip 6 can be used to abut and fix the pleated layers of the pleated filter bag 5 to prevent the pleated layers of the pleated filter bag 5 from being squeezed and stacked by the airflow, thereby effectively ensuring the cleaning effect of the pleated filter bag 5.

[0043] Furthermore, during the back-blowing cleaning of the pleated filter bag 5, some dust adheres to the inner wall of the housing 1. This causes the dust on the inner wall of the housing 1 to be drawn back to the outside of the pleated filter bag 5 when the exhaust gas is subsequently cleaned. As the cleaning plate 303 moves downward, the cleaning sponge 304 drives the cleaning plate 303 to wipe the inner wall of the housing 1, removing the dust adhering to the inner wall of the housing 1.

[0044] It should be noted that when cleaning the pleated filter bag 5 by blowing, the airflow from the nozzle 201 will also flow upward through the cleaning ring 4 and escape outward from the upper opening of the pleated filter bag 5, causing airflow turbulence. This prevents the airflow from concentrating on cleaning the uncleaned area on the lower side of the pleated filter bag 5, thus affecting the back-blowing effect on the pleated filter bag 5. When the high-pressure airflow enters the ventilation groove 4001 from the air inlet 4002, such as... Figure 6 As shown, the airflow enters the annular airbag 202 from the ventilation groove 4001, causing it to expand and contract inward. Thus, when the nozzle 201 sprays air downward, the annular airbag 202 blocks the airflow, preventing it from flowing upward through the cleaning ring 4. This allows the airflow to be concentrated on blowing the uncleaned area on the lower side of the pleated filter bag 5, thereby effectively ensuring the dust removal effect on the pleated filter bag 5.

[0045] Furthermore, when the solenoid valve at the connection between the compressed air tank and the vent pipe 306 is opened, it is first controlled to open to a small degree, allowing gas to be gradually blown into the vent groove 4001 from the air inlet 30501. At this time, the connecting channel 4003 is blocked by the sealing block 101. Under the elastic action of the elastic element 102, the air pressure in the vent groove 4001 cannot push the sealing block 101 to the left away from the connecting channel 4003. Thus, the gas in the vent groove 4001 first enters the annular air bladder 202, causing the annular air bladder 202 to expand and contract inward. Then, the solenoid valve at the connection between the compressed air tank and the vent pipe 306 is fully opened, increasing the air pressure inside the vent groove 4001. Figure 6 As shown, the blocking block 101 is pushed to the left away from the connecting channel 4003, so that the airflow enters the blowing groove 4004 through the connecting channel 4003 and is sprayed downward from the nozzle 201. This achieves the effect of first causing the annular airbag 202 to contract inward and then spraying the airflow downward, effectively ensuring the blocking effect of the annular airbag 202 on the airflow.

[0046] Example 2

[0047] Based on Example 1, such as Figures 1-5 As shown, the cleaning sponge 304 has bristles on the side near the pleated filter bag 5.

[0048] Since there may be a small amount of tightly adhered dust on the outer surface of the pleated filter bag 5 that cannot be blown away, the cleaning sponge 304 can be brushed by the bristles on the inner side of the cleaning sponge 304 as the cleaning plate 303 moves downward, thus brushing away the tightly adhered dust and effectively ensuring the dust removal effect of the pleated filter bag 5.

[0049] The above embodiments are provided for those skilled in the art to implement or use the present invention. Those skilled in the art can make various modifications or changes to the above embodiments without departing from the inventive concept of the present invention. Therefore, the protection scope of the present invention is not limited to the above embodiments, but should be the maximum scope that conforms to the innovative features mentioned in the claims.
