Description

Technical Field

[0001] This utility model relates to the field of dust collector technology, specifically to an industrial dust collector filter cartridge cleaning device. Background Technology

[0002] During the use of industrial dust collectors, the filter cartridges are prone to clogging due to dust. Therefore, industrial dust collector filter cartridge cleaning equipment is set up to clean the dust collector filter cartridges, effectively remove the dust attached to the filter cartridges, restore the filtration performance of the filter cartridges, ensure the continuous and efficient operation of the dust collector, and reduce equipment maintenance costs and production interruptions caused by filter cartridge clogging.

[0003] Chinese patent CN217068045U discloses a filter cartridge cleaning device, comprising: a housing with a filter cartridge support inside, on which the filter cartridge can be installed; a first driving device connected to the filter cartridge support for driving the filter cartridge support and the filter cartridge to rotate; a blowing mechanism disposed on the housing, which is located inside the filter cartridge when the filter cartridge is installed on the filter cartridge support; and a brush disposed on the housing, which is located on the outside of the filter cartridge and in contact with the outer wall of the filter cartridge when the filter cartridge is installed on the filter cartridge support. This invention can replace manual cleaning methods and achieve automatic cleaning of filter cartridges.

[0004] The aforementioned patent still has the following shortcomings: There are various brands and sizes of filter cartridges on the market. Existing cleaning equipment often has a fixed structure, making it difficult to adapt to filter cartridges of different diameters and heights. This requires operators to frequently change clamps or adjust equipment parameters, which not only increases the complexity of operation but may also cause the filter cartridge to shake during the cleaning process due to insecure fixing, affecting the cleaning effect or even causing damage to the filter cartridge. This defect restricts the versatility and efficiency of the equipment. Utility Model Content

[0005] This invention provides an industrial dust collector filter cartridge cleaning device that solves the problems mentioned in the background art.

[0006] To solve the above-mentioned technical problems, the technical solution of this utility model is as follows:

[0007] An embodiment of this utility model provides an industrial dust collector filter cartridge cleaning device, including a housing, and further comprising:

[0008] The hatch is rotatably connected to the inside of the top of the outer shell, and a support cylinder rotatably connected to the outer shell is installed on one side of the bottom end of the hatch. An observation window is installed inside one side of the hatch.

[0009] A lifting cylinder is installed inside the top of the hatch, and an electric roller brush is installed on the telescopic end of the lifting cylinder. Guide rods that are slidably connected to the hatch are installed on both sides of the top of the electric roller brush.

[0010] Support brackets are fixed to both sides of the top of the outer casing;

[0011] A dust filter plate is fixed to the bottom of the shell, and a dust discharge cover that is rotatably connected to the shell is provided on one side of the dust filter plate, and an exhaust pipe that is connected to the shell is provided on the other side of the dust filter plate.

[0012] An air guide shell is fixed to the other side of the outer shell, and an air intake solenoid valve is installed at the bottom end of one side of the air guide shell.

[0013] A positioning structure is provided on one side inside the housing. The positioning structure includes a drive motor fixed to the top of one side of the air guide housing, a transmission shaft installed at the end of the output shaft of the drive motor, a lead screw fixed to one side of the transmission shaft, a threaded sleeve threaded to the outside of the lead screw, a movable seat rotatably connected to the outside of the transmission shaft, a support arm rotatably connected to the outside of the threaded sleeve and the movable seat respectively, a support plate rotatably connected to the end of the support arm, and a transmission assembly provided between the movable seat and the housing.

[0014] A rubber pad is fixed to one side of the movable base.

[0015] The above technical solution involves extending the support cylinder to rotate and open the cover, placing the filter cartridge to be cleaned in the positioning structure inside the outer shell. The motor then drives the lead screw to rotate, causing the support arm to open the support plate and fix the filter cartridge. An electric roller brush cleans the outer wall of the filter cartridge. Simultaneously, high-pressure air passes through the air inlet solenoid valve, enters the filter cartridge through the air guide shell, and forms a backflow airflow. This airflow, combined with the brushing action of the electric roller brush, removes dust from the surface of the filter cartridge. The cleaned dust falls onto the dust filter plate and is finally discharged through the dust discharge cover, while the air is discharged from the equipment through the exhaust pipe.

[0016] Furthermore, the transmission assembly includes a sealing outer ring fixed to one side of the movable seat, a sealing inner ring fixed to the inner wall of the housing and rotatably connected to the sealing outer ring, a return spring installed on the outside of the transmission shaft, a baffle installed on one side of the return spring and slidably connected to the transmission shaft, and a fastener fixed to one side of the baffle.

[0017] The above technical solution uses air pressure to push the baffle backward so that the fastener is inserted into the air inlet of the moving seat. Then, the drive motor drives the transmission shaft to rotate slowly, causing the moving seat to rotate, which in turn drives the filter cartridge to rotate, thus achieving efficient cleaning of the filter cartridge.

[0018] Furthermore, the outer wall of the lead screw is provided with an external thread, and the inside of the screw sleeve is provided with an internal thread that cooperates with the external thread.

[0019] Through the above technical solution, the external thread on the outer wall of the lead screw and the internal thread inside the screw sleeve cooperate with each other, which can convert the rotational motion of the lead screw into the linear motion of the screw sleeve. This ensures the stability and controllability of the opening and closing action of the support plate to a certain extent, and enables the positioning structure to accurately adapt to filter cartridges of different sizes and achieve stable fixation.

[0020] Furthermore, several sets of support arms are provided on the outside of the threaded sleeve, and the several sets of support arms are arranged in a ring with equal spacing on the outside of the threaded sleeve.

[0021] The above technical solution, with the support arms arranged in a ring at equal intervals on the outside of the screw sleeve, can make the filter cartridge be subjected to uniform force during the fixing process to a certain extent, avoiding excessive local force that could damage the filter cartridge. At the same time, it improves the stability of the fixing, ensuring that the filter cartridge will not shake during the cleaning process and improving the cleaning effect.

[0022] Furthermore, a sealing ring is installed between the outer sealing ring and the inner sealing ring, and the outer sealing ring and the inner sealing ring form a damped rotational connection through the sealing ring.

[0023] The above technical solution, through the damped rotational connection between the sealing outer ring and the sealing inner ring, can ensure the sealing of the backflush airflow to a certain extent, while providing resistance to the rotation of the moving seat, so that the moving seat is less likely to rotate with the drive shaft when the filter cartridge is fixed.

[0024] Furthermore, the contact section between the drive shaft and the baffle is hexagonal, and the baffle has a matching hexagonal groove inside.

[0025] Through the above technical solution, the hexagonal contact section design between the drive shaft and the baffle allows the baffle to rotate when it slides on the drive shaft, cleverly converting the pneumatic drive into the rotational power of the filter cartridge and simplifying the transmission structure.

[0026] Furthermore, the interior of the movable base is provided with annularly arranged through holes, and the fastener and the through holes of the movable base form a plug-in structure.

[0027] Through the above technical solution, the annular arrangement of through holes and the insertion and removal structure of the fasteners inside the movable seat can ensure the smooth passage of the backflush airflow to a certain extent. At the same time, the connection and separation of the movable seat and the fasteners are realized under the push of air pressure, so that the filter cartridge can rotate in time when it needs to rotate and can quickly reset after the air supply stops.

[0028] The above-described solution of this utility model has at least the following beneficial effects:

[0029] This invention uses a drive motor to rotate a lead screw, which in turn moves a screw sleeve to move a support arm, thereby opening the support plate and tightly fitting it against the inner wall of the filter cartridge. This enables the device to be easily fixed, facilitating the fixing of filter cartridges of different sizes, greatly improving the versatility of the equipment, eliminating the need to replace dedicated cleaning equipment due to differences in filter cartridge specifications, and reducing the equipment procurement and maintenance costs for enterprises.

[0030] This invention uses air pressure to push the baffle back, causing the fastener to insert into the air inlet of the moving seat. This allows the drive motor to rotate the filter cartridge for cleaning, achieving efficient cleaning of the filter cartridge. This also enables the filter cartridge to rotate, reducing the fixed friction points between the electric roller brush and the filter cartridge, lowering the risk of localized wear, and allowing the electric roller brush to evenly cover the entire surface of the filter cartridge, thus improving dust removal efficiency.

[0038] Exemplary embodiments of the present invention will now be described in more detail with reference to the accompanying drawings. While exemplary embodiments of the present invention are shown in the drawings, it should be understood that the present invention may be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this invention will be thorough and complete, and will fully convey the scope of the invention to those skilled in the art.

[0039] like Figures 1 to 5 As shown, an embodiment of this utility model provides an industrial dust collector filter cartridge cleaning device, including a housing 1, and further comprising:

[0040] The hatch 2 is rotatably connected to the inside of the top of the outer shell 1, and a support cylinder 14 rotatably connected to the outer shell 1 is installed on one side of the bottom end of the hatch 2. An observation window 3 is installed inside one side of the hatch 2.

[0041] The lifting cylinder 12 is installed inside the top of the hatch 2, and the telescopic end of the lifting cylinder 12 is equipped with an electric roller brush 13. Guide rods 11 that are slidably connected to the hatch 2 are installed on both sides of the top of the electric roller brush 13.

[0042] Support frame 4 is fixed to both sides of the top of the outer casing 1;

[0043] The dust filter plate 6 is fixed at the bottom inside the outer shell 1, and a dust discharge cover 5 rotatably connected to the outer shell 1 is provided on one side of the dust filter plate 6, and an exhaust pipe 7 connected to the outer shell 1 is provided on the other side of the dust filter plate 6.

[0044] The air guide shell 10 is fixed on the other side of the outer shell 1, and an air intake solenoid valve 8 is installed at the bottom of one side of the air guide shell 10.

[0045] The positioning structure 9 is disposed on one side inside the outer casing 1. The positioning structure 9 includes a drive motor 901 fixed to the top of one side of the air guide shell 10, a transmission shaft 904 installed at the end of the output shaft of the drive motor 901, a lead screw 906 fixed to one side of the transmission shaft 904, a threaded sleeve 912 threaded to the outside of the lead screw 906, a movable seat 903 rotatably connected to the outside of the transmission shaft 904, a support arm 905 rotatably connected to the outside of the threaded sleeve 912 and the movable seat 903 respectively, a support plate 907 rotatably connected to the end of the support arm 905, and a transmission assembly disposed between the movable seat 903 and the outer casing 1.

[0046] Rubber pad 15 is fixed to one side of the movable seat 903.

[0047] In this embodiment of the utility model, the intake solenoid valve 8 is first connected to the factory's high-pressure air pipeline. When in use, the support cylinder 14 is activated to extend and push the cover 2 to rotate and open. The filter cartridge to be cleaned is placed in the positioning structure 9 inside the outer shell 1. The drive motor 901 is started, directly driving the lead screw 906 to rotate. At the same time, the rotation of the lead screw 906 causes the screw sleeve 912 to move, which in turn causes the support arm 905 to move. The support arm 905 then opens the support plate 907, which fits tightly against the inner wall of the filter cartridge, thus fixing the filter cartridge. At this time, the support cylinder 14 retracts to close the cover 2. Then, the lifting cylinder 12 is activated to drive the electric roller brush 13 to descend to the outside of the filter cartridge. The electric roller brush 13 then cleans the outer wall of the filter cartridge. At the same time, the high-pressure air is divided into two paths through the intake solenoid valve 8: the first path pushes the baffle 909 to insert the buckle 911 into the through hole of the moving seat 903; the second path enters the air guide shell 10 and directly enters the filter cartridge through the through hole of the moving seat 903 to form a backflush airflow.

[0048] The back-blowing airflow, in conjunction with the brushing action of the electric roller brush 13, removes dust from the surface of the filter cartridge. The cleaned dust falls onto the dust filter plate 6 and is eventually discharged through the dust discharge cover 5, while the air is discharged from the equipment through the exhaust pipe 7.

[0049] like Figures 3 to 5 As shown, the transmission assembly includes a sealing outer ring 908 fixed to one side of the movable seat 903, a sealing inner ring 902 fixed to the inner wall of the outer casing 1 and rotatably connected to the sealing outer ring 908, a return spring 910 installed on the outside of the transmission shaft 904, a baffle 909 installed on one side of the return spring 910 and slidably connected to the transmission shaft 904, and a fastener 911 fixed to one side of the baffle 909. The outer wall of the lead screw 906 is provided with an external thread, and the inside of the threaded sleeve 912 is provided with an internal thread that mates with the external thread. The support arm 905 rests on the threaded sleeve 912. Several sets of support arms 905 are arranged in a ring at equal intervals on the outside of the threaded sleeve 912. A sealing ring is installed between the sealing outer ring 908 and the sealing inner ring 902. The sealing outer ring 908 and the sealing inner ring 902 form a damped rotational connection through the sealing ring. The contact section between the drive shaft 904 and the baffle 909 is a hexagonal structure, and the baffle 909 has a matching hexagonal groove inside. The moving seat 903 has a ring of through holes inside. The fastener 911 and the through holes of the moving seat 903 form an insertion and removal structure.

[0050] In this embodiment of the utility model, when high-pressure air enters the air guide shell 10 through the air intake solenoid valve 8, the air pressure pushes the baffle 909 to overcome the elastic force of the return spring 910, causing the fastener 911 to be inserted into the air inlet of the movable seat 903. Then, the drive motor 901 drives the transmission shaft 904 to rotate slowly, so that the transmission shaft 904 drives the movable seat 903 to rotate through the baffle 909 and the fastener 911 in sequence, causing the filter cartridge to rotate, thus achieving efficient cleaning of the filter cartridge. Through the damped rotational connection between the sealing outer ring 908 and the sealing inner ring 902, the sealing of the backflush airflow can be guaranteed to a certain extent, while providing resistance to the rotation of the movable seat 903, so that the movable seat 903 does not easily rotate with the transmission shaft 904 when the filter cartridge is fixed.

[0051] The above description is the preferred embodiment of this utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of this utility model, and these improvements and modifications should also be considered within the protection scope of this utility model.
