Abstract
Description
An integrated air-blowing and dust-collecting cleaning and environmental protection device for bus air filters. Technical Field
[0001] This utility model relates to the technical field of air filter cleaning equipment, and in particular to an integrated air blowing and dust suction cleaning and environmental protection device for air filters in buses. Background Technology
[0002] Currently, over 90% of buses are pure electric vehicles. Electric air compressors and other equipment are equipped with air filters, which need to be cleaned periodically to ensure they are clean and functioning properly.
[0003] However, existing technologies generally rely solely on compressed air to blow clean the filter element, leading to secondary dust diffusion, polluting the workshop environment, and endangering the health of operators. Manual cleaning methods are inefficient, easily damaging the filter element's pore structure and shortening its service life. A single dust collection device cannot resolve the conflict between airflow from blowing and suction, resulting in unstable cleaning effects. Traditional cleaning methods cannot meet dust emission standards, leading to high frequency of filter replacement and high maintenance costs for buses.
[0004] Therefore, we propose an integrated air-blowing and dust-collecting cleaning and environmental protection device for bus air filters. Summary of the Invention

[0029] Example 1: An integrated air-blowing and dust-collecting cleaning and environmental protection device for bus air filters, as shown in Figure 1, includes a workbench 10. A cleaning cylinder 11 is fixedly installed on the top left side of the workbench 10. A sealing cap 12 is threadedly connected to the upper end of the outer wall of the cleaning cylinder 11. An air filter body 13 is installed at the bottom of the inner wall of the cleaning cylinder 11. An air-blowing module 14 is installed on the top right side of the inner wall of the workbench 10. A dust-collecting module 15 is installed in the middle of the top right side of the workbench 10. A linkage control unit 16 is installed at the front end of the top right side of the workbench 10. A sealing interface module 17 is installed on the top left side of the air-blowing module 14 inside the cleaning cylinder 11. The device integrates the air-blowing module 14 and the dust-collecting module 15. The high-pressure gas generated by the air blowing module 14, along with the linkage control unit 16, blows the air filter body 13 through a multi-hole nozzle, effectively removing dust and impurities adhering to the filter surface. The negative pressure fan in the dust collection module 15 generates strong suction, which draws the blown-down dust and impurities into the dust collection box through a multi-stage filter, preventing secondary dust diffusion and maintaining a clean working environment. The linkage control unit 16 monitors the working pressure of the air blowing module 14 and the dust collection module 15 in real time, and transmits the signals to the controller through the first pressure sensor and the second pressure sensor. The controller automatically adjusts the opening of the first pressure regulating valve and the second pressure regulating valve according to the preset program to ensure that the air blowing and dust collection processes are stable and efficient.
[0030] Example 2: Based on Example 1, as shown in Figure 2, the air blowing module 14 includes a high-pressure air pump, and the top of the high-pressure air pump is fixedly connected to the top right side of the inner wall of the workbench 10. A first pressure regulating valve is provided at the output end of the high-pressure air pump. A multi-hole nozzle is provided at the end of the first pressure regulating valve away from the high-pressure air pump via an air pipe, and the multi-hole nozzle is located inside the air filter body 13 inside the cleaning cylinder 11. The dust collection module 15 includes a dust collection box, and the bottom of the dust collection box is fixedly connected to the middle of the top right side of the workbench 10. A negative pressure fan is provided inside the dust collection box, and a second pressure regulating valve is provided at the output end of the negative pressure fan. A multi-stage filter is provided at the end of the second pressure regulating valve away from the negative pressure fan. The linkage control unit 16 includes a first pressure sensor, a second pressure sensor, and a controller. The first pressure sensor is located at the first pressure regulating valve, the second pressure sensor is located at the second pressure regulating valve, and the bottom of the controller is connected to the workbench 10. The top right front end of the unit 10 is fixedly connected. The controller is connected to the first pressure sensor, the second pressure sensor, the first pressure regulating valve, and the second pressure regulating valve via electrical signals. The sealing interface module 17 includes a threaded rod, and the bottom of the threaded rod is fixedly connected to the top of the multi-hole nozzle. A sealing cover is threadedly connected to the outer wall of the threaded rod. A sealing silicone pad is fixedly installed at the bottom of the sealing cover, and the bottom of the sealing silicone pad is in active contact with the top of the air filter body 13. By setting the sealing interface module 17, the design of the sealing interface module 17 ensures a tight connection between the air blowing module 14 and the air filter body 13. At the same time, the cooperation between the sealing cover and the sealing silicone pad further enhances the sealing performance of the connection, prevents gas leakage, and ensures the smooth progress of the cleaning process. The soft material of the sealing silicone pad can also effectively protect the top of the air filter body 13 and prevent damage during the cleaning process.
[0031] Example 3: Based on Examples 1 and 2, as shown in Figure 3, the multi-stage filter includes a pre-filter, a HEPA filter, and an activated carbon layer. By incorporating a multi-stage filter, inhaled dust and impurities can pass through the pre-filter, HEPA filter, and activated carbon layer, effectively removing fine particles and harmful gases, ensuring the cleanliness of the exhaust air, extending the maintenance cycle of the dust collection box and the entire device, and improving the practicality and durability of the equipment.
[0032] The working principle of this utility model:
[0033] In use, first, place the air filter body 13 to be cleaned into the cleaning cylinder 11 and seal the cleaning cylinder 11 with the sealing cap 12. Then, start the high-pressure air pump in the air blowing module 14. After the high-pressure gas is regulated by the first pressure regulating valve, it is delivered through the air pipe to the multi-hole nozzle to blow away the dust adhering to the filter element inside the air filter body 13. Simultaneously, the negative pressure fan in the dust collection module 15 starts, generating negative pressure. The suction force is adjusted by the second pressure regulating valve to draw the blown-off dust into the dust collection box. After filtration through a multi-stage filter, the dust is retained in the dust collection box, while clean air is discharged. During the blowing and dust collection process, the first and second pressure sensors monitor the pressure at the first and second pressure regulating valves in real time and transmit the signals to the controller. The controller adjusts the operating status of the high-pressure air pump and the negative pressure fan according to the received signals, ensuring that the dust collection negative pressure is 10% to 15% higher than the air blowing positive pressure. In addition, the use of threaded rods and sealing caps, along with the installation of sealing silicone gaskets, ensures a tight seal between the multi-hole nozzle and the air filter body 13, preventing dust leakage.
[0034] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims.
