Description

Technical Field

[0001] This application relates to the technical field of filter cartridge cleaning, and in particular to a filter cartridge pulse backflushing cleaning device. Background Technology

[0002] Filter cartridges are widely used in laser cutting, welding, spraying and other fields to filter dust from polluted air and discharge air that meets the standards. After a period of use, the surface of the filter cartridge will be covered with dust, which will reduce the filtration effect or even cause blockage. In this case, the filter cartridge needs to be replaced or the filter cartridge needs to be cleaned and dust removed.

[0003] With the development of technology, pulse backflushing technology has been gradually applied to filter cartridge cleaning. This technology uses compressed air to be ejected at high speed in a very short time to form a pulse airflow, which blows the filter cartridge in the opposite direction to remove dust. Compared with the earlier methods, the cleaning efficiency and effect are significantly improved. However, the design of the blowpipe of the traditional pulse backflushing device is unreasonable, which may lead to inconsistent backflushing air pressure and flow rate received by each filter cartridge, resulting in incomplete cleaning of some areas and incomplete backflushing effect. At the same time, the existing pulse backflushing rotary blade cleaning requires manual installation of filter cartridges, which is labor-intensive and prone to misalignment, resulting in unsatisfactory cleaning effect.

[0004] Regarding the aforementioned technologies, the applicant believes that they have the drawback of unsatisfactory backflushing effect. Utility Model Content

[0005] To address the aforementioned technical problems, this application provides a filter cartridge pulse backflushing cleaning device.

[0006] This application provides a filter cartridge pulse backflushing cleaning device, which adopts the following technical solution:

[0007] A filter cartridge pulse backflushing cleaning device includes a frame, on which a pulse backflushing cleaning mechanism, a control system, and a buffer gas storage system are mounted. The pulse backflushing cleaning mechanism is installed in the middle part inside the frame and is detachably connected to the frame. The control system is installed on the frame to one side of the pulse backflushing cleaning mechanism and is fixedly connected to the frame. The buffer gas storage system is installed on the frame above the control system and is detachably connected to the frame. The buffer gas storage system provides gas to the pulse backflushing cleaning mechanism. The control system is connected to both the pulse backflushing cleaning mechanism and the buffer gas storage system through specialized interfaces, and the control system is used to control both the pulse backflushing cleaning mechanism and the buffer gas storage system.

[0008] By adopting the above technical solution, the pulse backflushing cleaning mechanism and the slow storage gas system are detachably connected to the frame, while the control system is fixedly connected to the frame. The pulse backflushing cleaning mechanism is placed in the middle of the frame, allowing dust-laden gas to enter the equipment evenly for filtration. The slow storage gas system is installed on top of the control system, shortening the gas transmission path, reducing air pressure loss, and ensuring that high-pressure gas can be quickly and stably provided to the pulse backflushing cleaning mechanism. The pulse backflushing cleaning mechanism can rotate in all directions, and the spiral airflow it generates can clean the surface of the filter cartridge without dead angles, achieving a comprehensive backflushing effect on the filter cartridge. The control system is adjacent to the pulse backflushing cleaning mechanism and the slow storage gas system, and can be quickly connected and controlled through a professional interface. The manual feeding lifting mechanism automatically lifts the filter cartridge into position to complete the automatic sealing, with high positioning accuracy and good cleaning effect.

[0009] Preferably, the pulse backflushing cleaning mechanism includes a pulse control valve, an air blowing pipe, a backflushing rotary blade, a connecting plate, and a tapping cover. The connecting plate is installed between the tapping cover and the control valve in the middle part of the frame, and the connecting plate is detachably connected to the frame. One end of the air blowing pipe is installed on the pulse control valve, and the air blowing pipe is detachably connected to the pulse control valve.

The back-blowing rotary blade can rotate around the axis, and the rotation can achieve cleaning without dead angles. Compared with the fixed nozzle, it can cover a larger area of ​​the filter cartridge surface. The movable connection between the tapping cover and the air blowing pipe allows the tapping cover to move within a certain range, thereby achieving a more effective tapping cleaning function and further enhancing the cleaning effect of the pulse back-blowing cleaning mechanism.

[0011] Preferably, a lifting mechanism is provided below the pulse backflushing cleaning mechanism. The lifting mechanism includes lifting devices, a base plate, and a filter cartridge. One end of the two sets of lifting devices is installed on the frame on both sides of the pulse backflushing cleaning mechanism, and the lifting devices are detachably connected to the frame. The other end of the two sets of lifting devices is installed on both sides of the base plate, and the lifting devices are detachably connected to the base plate.

The first filter element is detachably connected to the air outlet. A second filter element is provided on the frame below the air outlet. The second filter element is detachably connected to the frame.

[0016] By adopting the above technical solution, the circulating fan, the first filter element, the second filter element and the frame are all detachably connected. The circulating fan can drive the air to circulate in the equipment, so that the dust-laden gas is filtered multiple times by the filter element, which enhances the filtration effect and improves the air purification efficiency. The dual filtration design of the first filter element and the second filter element can filter dust of different particle sizes in stages, further improving the filtration accuracy and ensuring that the discharged gas meets environmental protection standards.

[0019] Preferably, the frame of the pulse backflushing cleaning mechanism is provided with four movable doors, which are rotatably connected to the frame. Each movable door is provided with an observation window, which is fixedly connected to the movable door.

[0020] By adopting the above technical solution, the four movable doors are rotatably connected to the frame, providing a convenient passage for the inspection and maintenance of the internal components of the equipment. The observation windows set on the movable doors allow operators to observe the internal conditions of the equipment in real time without opening the movable doors during equipment operation, such as the dust accumulation on the surface of the filter cartridge, the working process of pulse backflushing, and the dust collection status.

[0021] Preferably, the movable door is provided with an emergency door handle and an access control switch. The emergency door handle is installed on the movable door and the frame and is detachably connected to the movable door and the frame.

[0032] The control system 4 is mounted on the frame 1 on one side of the pulse backflush cleaning mechanism 2. The control system 4 is fixedly connected to the frame 1. The slow-release gas storage system 5 is bolted to the frame 1 above the control system 4. The slow-release gas storage system 5 is connected to the pulse control valve 21 through a pipeline. The slow-release gas storage system 5 provides stable gas supply to the pulse backflush cleaning mechanism 2. The control system 4 is connected to the slow-release gas storage system 5 and the pulse backflush cleaning mechanism 2 through a professional interface. The control system 4 is used to control the pulse backflush cleaning mechanism 2 and the slow-release gas storage system 5. A circulating fan 18 is installed above the frame 1 on the other side of the pulse backflush cleaning mechanism 2. The circulating fan 18 is bolted to the frame 1 and can drive air to circulate inside the equipment. An air outlet 15 is installed on the frame 1 below the circulating fan 18. The air outlet 15 is fixedly connected to the frame 1. A first filter element 16 is installed at the air outlet 15. The first filter element 16 is detachably connected to the air outlet 15. A second filter element 17 is installed on the frame 1 below the air outlet 15. The second filter element 17 is detachably connected to the frame 1. The dual filtration design of the first filter element 16 and the second filter element 17 improves the filtration accuracy. A foot cup 12 is provided at the bottom of the frame 1, and the foot cup 12 is adjustablely connected to the frame 1. A fixed seat 13 is provided on one side of the frame 1 on the foot cup 12, and the fixed seat 13 is fixedly connected to the frame 1. Adjusting the foot cup 12 allows the frame 1 to be leveled, and the fixed seat 13 connects to the ground, further ensuring the stability of the equipment. Four movable doors 1 are provided on the frame 1 at the pulse backflushing cleaning mechanism 2. 4. The movable door 14 is rotatably connected to the frame 1. An observation window 143 is provided on the movable door 14. The observation window 143 is fixedly connected to the movable door 14. An emergency door handle 141 and an access control switch 142 are provided on the movable door 14. The emergency door handle 141 is installed on the movable door 14 and the frame 1 by bolts, so that the door and the door frame fit tightly to achieve a sealing structure. The access control switch 142 is installed on one side of the top of the movable door 14 by bolts. The access control switch 142 prevents the equipment from starting when the movable door 14 is not closed tightly.

[0033] The working principle of the filter cartridge pulse backflushing cleaning device in this application is as follows: The slow storage gas system 5 is the gas supply source. The stored compressed gas is connected to the pulse control valve 21 through the pipeline to provide high-pressure gas power for the pulse backflushing cleaning mechanism 2. The control system 4 is connected to the pulse backflushing cleaning mechanism 2 and the slow storage gas system 5 through a professional interface to control the start and stop and the running rhythm of the entire cleaning process. The control system 4 triggers the pulse control valve 21 to open, and the high-pressure gas in the slow storage gas system 5 is released through the blowing pipe 22 to form a pulse airflow. The pulse airflow enters the backflushing rotary blade 23 through the blowing pipe 22, pushing the backflushing rotary blade 23 to rotate so that the airflow evenly covers the surface of the filter cartridge 33, enhancing the backflushing effect. The patting cover 25 installed on the blowing pipe 22 pats the top of the filter cartridge 33 with the airflow pulsation, and the airflow impact causes the dust attached to the surface of the filter cartridge 33 to fall off. Two sets of lifting devices 31 are installed at both ends of the pulse backflushing cleaning mechanism 2. The two sets of lifting devices 31 can drive the base plate 32 to move up and down, accurately positioning the filter cartridge 33 at the pulse position. Below the back-blowing cleaning mechanism 2, ensure that the back-blowing rotating blade 23 is aligned with the filter cartridge 33 for easy all-round cleaning. After cleaning, the lifting device 31 can lower the filter cartridge 33 for easy disassembly or replacement. The dust collection drawer 11 is located at the bottom of the lifting mechanism 3. The dust that falls off during back-blowing falls into the dust collection drawer 11 for centralized cleaning. After the circulating fan 18 is started, the airflow first passes through the second filter element 17 for preliminary filtration, and then through the first filter element 16 for deep filtration. The purified air can be recycled or discharged. The feet 12 at the bottom of the frame 1 are height-adjustable to ensure that the equipment remains stable in different ground environments. The fixed base 13 is used to further fix the equipment and enhance stability. The four movable doors 14 on the frame 1 can be opened for easy installation and maintenance of the filter cartridge 33 and internal components. The observation window 143 allows real-time viewing of the cleaning process and monitoring of the status of the filter cartridge 33. The tight-fitting door handle 141 on the movable door 14 ensures that the door fits tightly with the door frame to form an efficient sealing structure. The access control switch 142 is linked to the equipment start-up system. The equipment is prohibited from starting when the movable door 14 is not closed tightly.

[0034] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
