Description

Technical Field

[0001] The utility model relates to the technical field of dust removal devices, in particular to an automatic dust removal device for filter elements. Background Technique

[0002] An automatic dust removal device for filter elements is an efficient cleaning device, which aims to drive the filter elements on a turntable through a high-speed pneumatic motor, separate dust from the filter elements by centrifugal force, and discharge the dust out of the tank body through a connected negative pressure dust suction pipe. The technical content disclosed in the Chinese patent document (application number: CN202122913583.5, patent name: Automatic dust removal device for dust collection filter elements of track maintenance machinery vehicles) is as follows: "It includes a negative pressure cabin body, a right-angle reduction motor, an air filter and an electric purging device. On one side surface of the negative pressure cabin body, there are a right-angle reduction motor, an air filter and an electric purging device. The filter element is installed on the surface of the rubber-coated idler roller of the negative pressure cabin body. The right-angle reduction motor drives the rubber-coated idler roller to rotate through a reducer. The rubber-coated idler roller will drive the filter element to rotate inside the negative pressure cabin body. During the rotation process, the electric purging device will automatically spray high-pressure gas. The high-pressure gas blows the tiny particles such as impurities attached to the filter element into the negative pressure cabin body.

Specific embodiments

[0023] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0024] Please refer to the attached Figures 1-9 , an embodiment provided by the present invention:

[0025] A filter element automatic dust removal device includes a dust removal assembly 1 and a dust suction pipe 2. The dust removal assembly 1 includes a tank body 102. The top of the tank body 102 is hinged to the top cover 101 through a hinge 110, enabling the top cover 101 to be conveniently opened and closed for cleaning and maintaining the inside of the tank body 102. A high-pressure spray pipe 104 is arranged inside the tank body 102, and the dust suction pipe 2 is communicated with the side wall and the bottom of the tank body 102 to ensure that dust can be smoothly sucked out. The dust removal assembly 1 is detachably connected to the trolley 3 for facilitating the movement and fixing of the entire device. A foot pedal 4 is arranged on one side of the trolley 3, facilitating the operator to stand on the foot pedal 4 to open the top cover 101 and place the filter element 5.

[0026] A number of latches 103 are provided on the open outer edge of the tank body 102. These latches 103 are matched with the locking parts of the top cover 101. When the top cover 101 is closed, it is firmly fixed on the tank body 102 through the latches 103 to ensure sealing and safety.

[0027] A high-speed pneumatic motor 105 is installed inside the tank body 102. The high-speed pneumatic motor 105 drives the turntable 107 through the connecting shaft 106, and a filter element 5 is installed on the turntable 107. When the high-speed pneumatic motor 105 is started, it drives the turntable 107 to rotate at a high speed, and the filter element 108 separates the attached dust under the action of centrifugal force.

[0028] Centrifugal force is an inertial force. When the filter element 5 rotates at a high speed, the dust particles on the filter element are thrown radially towards the outer edge of the filter element 5 and separated from the surface of the filter element under the action of centrifugal force. These separated dust particles are jointly affected by the airflow ejected from the high-pressure nozzle 104 and the suction force generated by the suction pipe 2 inside the tank body 102, are sucked into the suction pipe 2, and are discharged from the tank body 102 through negative pressure, and finally enter the external collection device to realize the automatic cleaning of the filter element.

[0029] The function of the high-pressure nozzle 104 is to further enhance the cleaning effect of the filter element 5 through high-pressure airflow. After the filter element 108 throws off the dust from the surface under the action of centrifugal force, the high-pressure nozzle 104 can blow off some stubborn and tightly adhered dust particles from the filter element 108 by ejecting high-pressure airflow. At the same time, the high-pressure airflow can also prevent dust from depositing inside the tank body 102, ensuring that the dust can be quickly brought into the suction pipe 2 and discharged from the tank body 102.

[0030] Specifically, the high-pressure nozzle 104 can accurately spray on specific areas of the filter element 108 through the preset nozzle direction and angle. During the process of the high-speed pneumatic motor 105 driving the turntable 107 to rotate, the high-pressure nozzle 104 can ensure that all parts of the filter element 108 are cleaned through intermittent or continuous airflow spraying, improving the overall cleaning efficiency and extending the service life of the filter element.

[0031] A number of nozzles 10401 are provided on the body of the high-pressure nozzle 104. These nozzles 10401 are evenly distributed on the high-pressure nozzle 104 and can eject high-pressure airflow to clean the filter element 5. The high-pressure nozzle 104 is located on the central axis of the tank body 102 to ensure that the airflow can cover the entire area of the filter element 5, thereby improving the cleaning efficiency. A number of turntables 7 are arranged around the high-pressure nozzle 104. The turntables 7 are connected to the pneumatic motor 6 through a detachable structure, making it more convenient to maintain and replace the appropriate turntable 7 according to the model of the filter element 5. The pneumatic motor 6 provides power and drives the turntable 7 to rotate, so that the filter element 5 separates the dust from the surface of the filter element under the action of centrifugal force, thereby realizing the automatic cleaning of the filter element 5.

[0032] A positioning shaft 701 parallel to the high-pressure nozzle 104 is provided in the middle of the turntable 7. The filter element 5 is inserted into the positioning shaft 701 to ensure that the filter element 5 remains stable during the high-speed rotation of the turntable 7, avoiding deviation or shaking, so as to ensure uniform force on the filter element 5. A number of buckles 702 are provided on the outer edge of the turntable 7. These buckles 702 are used to fix the filter element 5, making it firmly attached to the turntable 7 and not falling off or shifting during rotation. The design of the buckles 702 makes the installation and disassembly of the filter element 5 more convenient and fast, while ensuring the cleaning effect. Through this design, the filter element automatic dust removal device can operate efficiently and stably.

[0033] A conical tank bottom 107 is provided at the bottom of the top cover 101, which helps to concentrate the dust on the filter element 5 to the dust collection port. A first dust collection port 105 is provided on the side wall of the tank body 102, and a second dust collection port 106 is provided at the center of the tank bottom 107, facilitating multi-point dust collection and further improving the dust removal efficiency. The suction pipe 2 is simultaneously connected to the first dust collection port 105 and the second dust collection port 106 to ensure that the dust at various positions of the tank body 102 can be effectively sucked away.

[0034] The suction pipe 2 includes a first pipe fitting 201, a second pipe fitting 202, and a third pipe fitting 203. One end of the third pipe fitting 203 is connected to the second dust collection port 106, and the other end is connected to the second pipe fitting 202 to ensure that the dust is sucked away from the center of the tank bottom 107. The middle is connected to the first dust collection port 105 to ensure that the dust on the side wall can also be sucked away. The third pipe fitting 203 is located between the second pipe fitting 202 and the first dust collection port 105, and the pipeline is reasonably arranged to ensure the efficient operation of the suction pipe 2 system.

[0035] An installation opening 302 is provided on the supporting surface of the trolley 3. The installation opening 302 is matched with the dust removal assembly 1 for stable installation and disassembly of the dust removal assembly 1. The trolley 3 is provided with a handrail 301 for easy operation by the operator to push and control the trolley. Wheels 303 are provided at the bottom to ensure that the device can be easily moved and improve flexibility.

[0036] The footrest 4 includes a grid platform 401, providing a firm and anti-slip operating surface. The footrest 4 is connected to the trolley 3 through a connecting piece 403 to ensure stable structure. The grid platform 401 is rotatably connected to the connecting piece 403 through a bearing 402, so that the grid platform 401 can rotate flexibly for easy operation. A locking crossbar 404 is provided on the ground of the grid platform 401 to ensure that the footrest can be fixed at the required position during use. A handle 405 is provided on the top of the grid platform 401 for easy operation by the operator to adjust and fix the position of the footrest.

[0037] The working mode of this device is as follows: The operator first opens the top cover 101, places the filter element 5 on the turntable 7. During operation, the operator can put down the footrest 4 and stand safely on the footrest 4 to ensure the safety of the operation. After placing the filter element 5, close the top cover 101 and lock the lock catch 103. Start the device, and the high-speed pneumatic motor 6 starts to operate, driving the filter screen connected to the turntable 7 to rotate. At the same time, the high-pressure nozzle 104 starts to spray high-pressure gas to clean the surface of the filter element 5. The centrifugal force generated when the filter element 5 rotates separates the dust attached to the filter screen. The dust collection pipe 2 discharges the dust collected from the first dust collection port on the side wall of the tank body 102 and the second dust collection port 106 at the center of the tank bottom 107 through negative pressure, achieving the purpose of dust removal and dust collection.

[0038] Through the above steps, this device can efficiently remove the dust on the filter element 5, ensure the continuous use performance of the filter element 5, and at the same time ensure the convenience of operation and the cleanliness of the environment through reasonable structural design.
