Description

Technical Field

[0001] This invention relates to the field of baghouse dust collector technology, and more specifically to a mobile baghouse dust collector with adjustable airflow. Background Technology

[0002] A baghouse dust collector is a dry dust filtration device. It is suitable for collecting fine, dry, non-fibrous dust. The filter bags are made of woven filter cloth or non-woven felt, utilizing the filtration effect of the fibrous fabric to filter dust-laden gas. When the dust-laden gas enters the baghouse dust collector, larger, heavier dust particles settle down due to gravity and fall into the ash hopper. The gas containing finer dust particles is purified as it passes through the filter media, as the dust is trapped.

[0003] In existing baghouse dust collectors, after a period of use, a significant amount of dust accumulates on the surface of the filter bags. To ensure good filtration efficiency, the filter bags need to be periodically cleaned by an automatic dust removal mechanism installed inside the dust collector. Since the automatic dust removal mechanism is usually located above the filter bags, if the cleaning time is too short, the dust on the surface of the filter bags cannot be effectively removed. This causes the filtration operation to resume before the dust has been completely removed, resulting in a rapid increase in the internal resistance of the filter bags, which affects the performance of the baghouse dust collector and reduces its filtration efficiency for dusty gases. Summary of the Invention

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a mobile adjustable airflow bag filter.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A mobile adjustable airflow bag filter includes a mobile base and a filter body. A bracket is installed on the top of the mobile base, and the filter body is installed inside the bracket. Three fixed plates are installed inside the filter body, and multiple filter bags are installed inside each of the three fixed plates. Three first cleaning mechanisms for auxiliary dust removal of the filter bags are installed inside the filter body. Automatic dust removal mechanisms are installed above the three fixed plates inside the filter body. A second cleaning mechanism for auxiliary cleaning of the components of the automatic dust removal mechanism is installed on the inner top surface of the filter body.

[0007] Optionally, the dust collector body has three dust hoppers at the bottom, an air inlet on one side, and three inspection doors on the front.

[0008] Optionally, a fan is installed on the top of the movable base, an exhaust pipe is installed on one side of the top of the dust collector body, the end of the exhaust pipe away from the dust collector body is connected to the input end of the fan, and an exhaust pipe is installed at the output end of the fan.

[0009] Optionally, each of the three fixing plates has multiple mounting slots inside, and multiple bag bodies are respectively installed inside the multiple mounting slots, with bag frames inserted inside the multiple bag bodies.

[0010] Optionally, the automatic dust removal mechanism includes multiple blowpipes, all of which are installed inside the dust collector body and located above three fixed plates. The bottom ends of the multiple blowpipes are equipped with blowheads that face into the multiple filter bags.

[0011] Optionally, the first cleaning mechanism includes three movable plates disposed inside the dust collector body. The outer walls of the three movable plates are each equipped with scrapers adapted to the dust collection chamber inside the dust collector body. Multiple sets of winding wheels are rotatably mounted on both outer walls of the dust collector body via multiple rotating shafts. Steel wire ropes are wound around the outside of the multiple sets of winding wheels. The ends of the multiple sets of steel wire ropes away from the winding wheels pass through the dust collector body and are connected to their corresponding movable plates.

[0012] Optionally, each of the three movable plates is equipped with a plurality of first electric telescopic rods at its bottom. The telescopic ends of the plurality of first electric telescopic rods pass through the corresponding movable plate and are connected to the movable frame. Circular airbags are installed on the multiple circular inner walls inside the three movable frames. Two connecting ends that pass through the movable plate are installed at the bottom of each of the three movable frames.

[0013] Optionally, the second cleaning mechanism includes a plurality of second electric telescopic rods installed on the top surface of the dust collector body. Each of the telescopic ends of the plurality of second electric telescopic rods is equipped with a motor, and each of the output ends of the plurality of motors is equipped with a rotating seat.

[0014] Optionally, each of the multiple rotating seats has four rotating blocks rotatably installed inside. Each of the four rotating blocks has a rotating plate rotatably installed at the end away from the rotating seat via a connecting shaft. The upper and lower outer walls of the four rotating plates are fitted with soft pads, and an industrial camera is installed on one outer wall of each of the four rotating plates.

[0015] The beneficial effects of this invention are:

[0016] 1. In this invention, after the automatic dust removal mechanism cleans the dust accumulated on the surface of the filter bag, the first cleaning mechanism set inside the dust collector body can automatically clean the dust on the outer wall of the filter bag body that could not be removed by the automatic dust removal mechanism, so as to improve the cleaning effect on the dust on the outer wall of the filter bag body and facilitate the subsequent use of the filter bag body.

[0017] 2. In this invention, since scrapers are installed on the outer walls of the three moving plates, the three moving plates can be driven to move up and down continuously inside the dust collector body through the cooperation of the rotating shaft, the winding wheel and the wire rope. This allows the three scrapers to automatically scrape and clean the dust attached to the inner wall of the corresponding dust collection chamber, avoiding the problem that the dust attached to the inner wall of the dust collector body cannot be automatically removed, and further improving the cleanliness of the inside of the dust collector body.

[0018] 3. In this invention, since multiple nozzles at the bottom of multiple blowpipes are positioned directly above multiple bag bodies, multiple second electric telescopic rods are controlled to move the soft pads on the top of multiple rotating plates to a state flush with the bottom of the nozzles. As multiple motors are controlled to drive the corresponding rotating seats to rotate, multiple soft pads can be driven to rotate synchronously, so that multiple soft pads can respectively rub and clean the dust accumulated at the bottom of the four nearby nozzles, maintain the good air jet effect of the nozzles, and reduce the adverse effects of dust on the nozzles.

[0019] 4. In this invention, before the compressed gas is ejected outward from the multiple blowpipes, multiple motors can be controlled to drive the corresponding rotating seats and four rotating plates to move to the bottom of two adjacent blowpipes respectively. Multiple second electric telescopic rods are controlled to drive the soft pads at the top of the four rotating plates to tightly abut against the bottom of the blowpipes, thereby achieving the effect of assisting in lifting and limiting the multiple blowpipes. This avoids the problem that when multiple blowpipes eject compressed gas outward, the compressed gas is quickly discharged from the inside of the blowpipes, causing vibration during blowing and affecting the stability of the blowpipes.

[0032] The technical solution of the present invention will be clearly and completely described below with reference to the embodiments. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0033] Reference Figures 1-10 A mobile adjustable airflow bag filter includes a mobile base 1 and a filter body 2. A bracket 9 is installed on the top of the mobile base 1. The filter body 2 is installed inside the bracket 9. Three fixing plates 10 are installed inside the filter body 2. Multiple filter bags 11 are installed inside each of the three fixing plates 10. Three first cleaning mechanisms for auxiliary dust removal of the filter bags 11 are installed inside the filter body 2. Automatic dust removal mechanisms are installed above the three fixing plates 10 inside the filter body 2. A second cleaning mechanism for auxiliary cleaning of the components of the automatic dust removal mechanism is installed on the inner top surface of the filter body 2.

[0034] As a technical optimization of the present invention, three dust hoppers 4 are provided at the bottom of the dust collector body 2, an air inlet 3 is installed on one side of the dust collector body 2, and three inspection doors 5 are installed on the front of the dust collector body 2.

[0035] As a technical optimization of the present invention, a fan 6 is installed on the top of the mobile base 1, and an exhaust pipe 7 is installed on one side of the top of the dust collector body 2. The end of the exhaust pipe 7 away from the dust collector body 2 is connected to the input end of the fan 6, and an exhaust pipe 8 is installed at the output end of the fan 6. By starting the fan 6, dust-laden gas from the outside enters the interior of the dust collector body 2 through the air inlet 3. After being filtered by multiple filter bags 11, the clean gas can be discharged to the outside through the exhaust pipe 7 and the exhaust pipe 8.

[0036] As a technical optimization of the present invention, each of the three fixing plates 10 has multiple mounting slots 15 inside, and multiple bag bodies 11 are respectively installed inside the multiple mounting slots 15. Each bag body 11 has a bag frame inserted inside it. After the bag body 11 is inserted into the mounting slot 15 from top to bottom, the bag frame is then inserted into the bag body 11 to ensure that the bag body 11 maintains good stability during use.

[0037] As a technical optimization of the present invention, the automatic dust removal mechanism includes multiple blowpipes 13, all of which are installed inside the dust collector body 2 and located above three fixed plates 10. Each blowpipe 13 has a blowhead 16 at its bottom end, pointing towards the interior of multiple bag bodies 11. The baghouse dust collector uses multiple bag bodies 11 to filter dust from the inside of the dust-laden gas. The dust is trapped on the surface of the bag bodies 11. As dust accumulates, the resistance of the bag bodies 11 increases, requiring regular cleaning to restore filtration efficiency. When cleaning of the bag bodies 11 is required, the multiple blowheads 16 at the bottom of the multiple blowpipes 13 are controlled to generate a high-speed airflow through pulsed compressed air jets, impacting the bag bodies 11 to cause them to expand and vibrate. This allows the dust to automatically fall from the surface of the bag bodies 11, achieving the effect of automatic dust removal.

[0038] As a technical optimization of the present invention, the first cleaning mechanism includes three movable plates 12 disposed inside the dust collector body 2. The outer walls of the three movable plates 12 are all equipped with scrapers 21 adapted to the dust removal chamber inside the dust collector body 2. The outer walls on both sides of the dust collector body 2 are rotatably mounted with multiple sets of winding wheels 18 through multiple rotating shafts 17. Steel wire ropes 19 are wound around the outside of the multiple sets of winding wheels 18. The ends of the multiple sets of steel wire ropes 19 away from the winding wheels 18 pass through the dust collector body 2 and are connected to their corresponding movable plates 12. Multiple first drive devices are installed on both outer walls of the dust collector body 2. The output ends of the multiple first drive devices are connected to one end of the adjacent rotating shaft 17, thereby driving the multiple rotating shafts 17 and the winding wheels 18 installed at both ends to rotate together. As the winding wheels 18 rotate, the steel wire rope 19 on its outer wall can be wound up or unwound downwards, so as to drive the moving plate 12 to move up and down in the corresponding dust removal chamber. Since a scraper 21 is installed on the outer wall of the moving plate 12, the scraper 21 can be driven to move up and down in the corresponding dust removal chamber simultaneously during the up and down movement of the moving plate 12, so as to facilitate the automatic scraping of dust attached to the dust removal chamber.

[0039] As a technical optimization of the present invention, a plurality of first electric telescopic rods 22 are installed at the bottom of each of the three movable plates 12. The telescopic ends of the plurality of first electric telescopic rods 22 pass through the corresponding movable plates 12 and are connected to the movable frame 20. A plurality of circular airbags 26 are installed on the inner walls of the three movable frames 20. Two connecting ends 23 with their bottom ends passing through the movable plates 12 are installed at the bottom of each of the three movable frames 20. During the use of the multiple first electric telescopic rods 22, retractable protective covers are installed on their surfaces to ensure that the multiple first electric telescopic rods 22 can be used normally inside the dust collector body 2. During the extension and retraction of the multiple first electric telescopic rods 22, they can drive the moving frame 20 to move up and down synchronously inside the moving plate 12. Inside the dust collector body 2, multiple hoses connected to the connecting end 23 are installed. The other end of the multiple hoses is connected to an externally preset air pump, so that after the external air pump is started, it delivers air into the interior of the moving frame 20 through the hoses, causing the multiple circular airbags 26 to inflate and expand. Since the air inlet end of the multiple circular airbags 26 is equipped with a solenoid valve, after the gas enters the interior of the moving frame 20, the opening and closing of the solenoid valves corresponding to the multiple circular airbags 26 can control the inflation and expansion of the circular airbags 26 in use.

[0040] As a technical optimization of the present invention, the second cleaning mechanism includes multiple second electric telescopic rods 14 installed on the top surface inside the dust collector body 2. Each telescopic end of the multiple second electric telescopic rods 14 is equipped with a motor 27, and each output end of the multiple motors 27 is equipped with a rotating seat 28. During the telescopic process, the telescopic ends of the multiple second electric telescopic rods 14 can drive the corresponding motors 27 and rotating seats 28 to move up and down together for adjustment; the motors 27 can drive the rotating seats 28 to rotate for adjustment.

[0041] As a technical optimization of the present invention, four rotating blocks 29 are rotatably installed inside each of the multiple rotating seats 28. A rotating plate 30 is rotatably installed on the end of each of the four rotating blocks 29 away from the rotating seat 28 via a connecting shaft. Soft pads 31 are installed on the upper and lower outer walls of each of the four rotating plates 30, and an industrial camera 32 is installed on one outer wall of each of the four rotating plates 30. Four second driving devices are pre-installed outside the rotating seats 28, and the output ends of the four second driving devices are respectively connected to the rotating parts of one end of the corresponding rotating block 29, thereby enabling the four rotating blocks 29 to rotate and adjust inside the corresponding rotating seats 28. A third driving device is pre-installed inside each of the four rotating blocks 29, and the output ends of the four third driving devices are respectively connected to their corresponding connecting shafts, thereby enabling the four rotating plates 30 to rotate and adjust. The industrial camera 32 is a FRAMOS-D400e series industrial camera in the prior art.

[0042] In this invention, when the user uses the device, after transporting the entire device to the desired location via a large truck, the device can be moved and adjusted on the ground at the designated location using multiple rollers at the bottom of the mobile base 1. After the device is moved to the appropriate position, the fan 6 is started, and the pipe for conveying dust-laden gas is connected to the air inlet 3. After the dust-laden gas enters the interior of the dust collector body 2, it can be automatically filtered by multiple filter bags 11 inside the multiple dust collection chambers. Larger dust particles can automatically fall downwards into the ash hopper 4, and clean gas can be discharged outwards through the exhaust pipe 7 and the exhaust pipe 8, achieving the effect of automatically removing and filtering dust-laden gas.

[0043] Since all three movable plates 12 can be moved up and down inside the dust collector body 2, and the multiple circular airbags 26 can be freely adjusted in size during use, when it is necessary to adjust the air volume entering the dust collector body 2, the three movable plates 12 can be controlled to move down inside the dust collector body 2 to a position lower than the filter bag body 11, and the expansion and contraction of the multiple circular airbags 26 can be controlled, so that the maximum air volume allowed to pass through the multiple circular slots 24 can be changed. Thus, the air volume entering the dust collector body 2 can be freely adjusted according to the actual usage requirements.

[0044] After a period of use, a lot of dust will accumulate on the surface of the multiple filter bags 11 inside the dust collector body 2. At this time, compressed gas can be transported to the interior of multiple blow pipes 13 through the preset pipes inside the dust collector body 2, and multiple blow nozzles 16 at the bottom of the multiple blow pipes 13 can be controlled to generate high-speed airflow by pulse blowing compressed air, which impacts the filter bags 11 to make them expand and vibrate, so that the dust can automatically fall from the surface of the filter bags 11 downwards into the ash hopper 4 below, thus achieving the effect of automatic dust removal of the filter bags 11.

[0045] While the automatic dust removal mechanism uses compressed air to remove dust from multiple filter bag bodies 11, some dust will still remain on the surface of the filter bag bodies 11. At this time, multiple rotating shafts 17 on both sides of the outer wall of the dust collector body 2 can be controlled to rotate synchronously, driving multiple sets of winding wheels 18 to rotate together and winding multiple steel wire ropes 19. This causes the three moving plates 12 to move upward inside the dust collector body 2 until they are flush with the top of the multiple filter bag bodies 11. Then, the external preset air pump is started to inflate the multiple circular air bags 26 inside the three moving frames 20, so that after the multiple circular air bags 26 are inflated and expanded, their inner walls can be flush with the outer walls of the corresponding filter bag bodies 11. Upon contact, multiple rotating shafts 17 are controlled to rotate synchronously in reverse, causing multiple steel wire ropes 19 to unfold downwards together. With the help of the gravity of the three moving plates 12 and their internal components, the three moving plates 12 move downwards together inside the dust collector body 2, causing the inner walls of multiple circular air bags 26 to rub against the outer walls of multiple filter bags 11. This automatically cleans the dust on the outer walls of the filter bags 11 that could not be removed by the automatic dust removal mechanism. The multiple rotating shafts 17 can continue to rotate in both directions, causing the three moving plates 12 to move up and down continuously inside the dust collector body 2, thereby improving the cleaning effect on the outer walls of the filter bags 11 and facilitating the subsequent use of the filter bags 11.

[0046] Since scrapers 21 are installed on the outer walls of the three moving plates 12, the three moving plates 12 can be driven to move up and down inside the dust collector body 2 through the cooperation of the rotating shaft 17, the winding wheel 18 and the wire rope 19. This allows the three scrapers 21 to automatically scrape and clean the dust attached to the inner wall of the corresponding dust collection chamber, avoiding the problem that the dust attached to the inner wall of the dust collector body 2 cannot be automatically removed, and further improving the cleanliness of the inside of the dust collector body 2.

[0047] If one or more of the filter bag bodies 11 are damaged, the damaged filter bag body 11 needs to be removed from the dust collector body 2 and replaced with a new filter bag body 11. After opening the top cover of the dust collector body 2, the multiple blow pipes 13 are removed from the top of the fixed plate 10. Then, through the cooperation between the rotating shaft 17, the winding wheel 18 and the wire rope 19, the corresponding moving plate 12 is driven to move downward inside the dust collector body 2 to a position lower than the filter bag body 11. The circular air bladder 26 directly below the damaged filter bag body 11 is controlled to inflate to its maximum state, so that the inner walls of the circular air bladder 26 come into contact with each other. The inside of the circular groove 24 is sealed off. Then, with the cooperation of the rotating shaft 17, the winding wheel 18 and the wire rope 19, the corresponding moving plate 12 is pulled upward inside the dust collector body 2. This causes the circular airbag 26, which is located directly below the damaged filter bag body 11, to expand and push the damaged filter bag body 11 upward. This automatically and quickly pushes the damaged filter bag body 11 upward from inside the fixed plate 10 without affecting the stability of other intact filter bag bodies 11. This makes it easy for staff to quickly remove and replace the damaged filter bag body 11.

[0048] If a large number of filter bag bodies 11 are being replaced, in order to protect these newly installed filter bag bodies 11 and extend their service life, a pre-coating process is required on the new filter bag bodies 11. This allows the dust to form a stable filter layer on the surface of the filter bag body 11 in advance, preventing dust penetration and blocking sticky substances from directly contacting the filter bag fibers, which could lead to bag clogging. In this case, the three moving plates 12 can be controlled to move downwards inside the dust collector body 2 to a position close to the ash hopper 4, and the multiple large circular air bags 26 inside the three moving frames 20 can be controlled to inflate to their maximum size. So that the multiple expanded circular airbags 26 can seal the corresponding circular grooves 24 respectively, the staff can then open the three inspection doors 5 and place the prepared dust materials, such as lime powder, fly ash, diatomaceous earth and other materials close to the actual dust, on the top of the three moving plates 12. After starting the fan 6, the dust materials on the top of the three moving plates 12 can be adsorbed onto the surface of multiple new filter bag bodies 11, achieving the effect of pre-coating the surface of the new filter bag bodies 11 with ash, and building a protective layer on the outer surface of the new filter bag bodies 11 in advance, extending the service life of the filter bag bodies 11 by more than 30%.

[0049] Since the multiple nozzles 16 at the bottom of the multiple blowpipes 13 are all located directly above the multiple bag bodies 11, if the bag body 11 is damaged during use, some dust will accumulate at the bottom of the nozzles 16, causing the nozzles 16 to become clogged during use, which will affect the dust removal effect on the bag body 11. The telescopic ends of the multiple second electric telescopic rods 14 can be controlled to retract upwards together, causing the soft pads 31 on the top of the multiple rotating plates 30 to move to a state flush with the bottom of the nozzles 16. As the multiple motors 27 drive the corresponding rotating seats 28 to rotate, the multiple rotating plates 30 and their top soft pads 31 can be driven to rotate synchronously, so that the multiple soft pads 31 can rub and clean the dust accumulated at the bottom of the four nearby nozzles 16, maintain the good air jet effect of the nozzles 16, and reduce the adverse effects of dust on the nozzles 16.

[0050] Meanwhile, before the multiple blowpipes 13 spray compressed gas outward, multiple motors 27 can be controlled to drive the corresponding rotating seats 28 to rotate 45 degrees together, driving the four rotating plates 30 to move to the bottom of the two adjacent blowpipes 13 respectively. After the telescopic ends of multiple second electric telescopic rods 14 are controlled to retract upward a certain distance, the soft pads 31 at the top of the four rotating plates 30 can be driven to tightly abut against the bottom of the blowpipes 13, achieving the effect of assisting in lifting and limiting the multiple blowpipes 13. This avoids the problem of compressed gas being quickly discharged from the inside of the blowpipes 16 when multiple blowpipes 16 spray compressed gas outward, causing the blowpipes 13 to vibrate and affecting the stability of the blowpipes 13.

[0051] Furthermore, when the moving plate 12 moves up and down in conjunction with the expanding circular airbag 26 to assist in cleaning the dust on the outer walls of multiple bag bodies 11, multiple motors 27 can be controlled to drive the corresponding rotating seats 28 to rotate 45 degrees, thereby moving the four rotating plates 30 to the top of the four bag bodies 11 respectively. The telescopic ends of multiple second electric telescopic rods 14 are controlled to extend downward together, so that the soft pads 31 at the bottom of the four rotating plates 30 can be tightly pressed against the top of the corresponding bag body 11, thereby achieving the effect of pressing and limiting the bag body 11 that is currently undergoing dust cleaning, avoiding affecting the stability of the bag body 11 that is currently undergoing dust cleaning, and facilitating the subsequent use of the bag body 11.

[0052] Furthermore, since industrial cameras 32 are installed on the outer side of each of the multiple rotating plates 30, after the multiple blowpipes 13 have been used for a period of time, the outer wall of the multiple rotating plates 30 with the industrial cameras 32 installed can be controlled to rotate upward to the top. In conjunction with the motor 27 driving the rotating seat 28 and the four rotating plates 30 to rotate 45 degrees, the four rotating plates 30 are driven to rotate directly below the corresponding blowpipes 16. The position of the four blowpipes 16 is automatically identified and detected to ensure that the compressed gas ejection direction of the multiple blowpipes 16 is relatively accurate, which can ensure that the subsequent automatic dust removal mechanism has a good dust removal effect on the multiple bag bodies 11.

[0053] Furthermore, when it is necessary to test the sealing performance of the blowpipe 13 and blowhead 16 after prolonged use, multiple motors 27 can be controlled to drive multiple rotating seats 28 to rotate 45 degrees together. This causes the four rotating plates 30 to rotate directly below the corresponding blowhead 16. With the upward retraction of the extension ends of multiple second electric telescopic rods 14, the soft pads 31 on the top of the four rotating plates 30 are brought into close contact with the bottom of the corresponding blowhead 16, thus sealing the bottom of the multiple blowheads 16. When the multiple blowpipes 13 are transporting gas, the sealing performance between the multiple blowheads 16 and the blowpipes 13 can be quickly tested using relevant pressure testing equipment, preventing air leakage between the blowheads 16 and the blowpipes 13, which could affect the use of the automatic dust removal mechanism.
