[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] Please see Figure 1-5 The present invention provides the following technical solution: An automatic filter cleaning device includes a filter body 1, a cleaning mechanism 2 is provided in the inner cavity of the filter body 1, and a monitoring mechanism 3 is provided on the front side of the filter body 1. The cleaning mechanism 2 includes a gearbox 21 and a drive motor 22. The gearbox 21 is located at the bottom of the inner cavity of the filter body 1. The drive motor 22 is fixedly connected to the bottom right side of the filter body 1. The output shaft of the drive motor 22 is fixedly connected to a transmission rod 23. The left side of the transmission rod 23 passes through the filter body 1 and extends into the gearbox 21. The left side of the transmission rod 23 is fixedly connected to a transmission bevel gear 24. The left side of the top of the transmission bevel gear 24 is meshed with a driven bevel gear 25. The top of the driven bevel gear 25 is fixedly connected to a rotating rod 26. The top of the rotating rod 26 passes through to the top of the gearbox 21 and is fixedly connected to a U-shaped frame 27. A U-shaped cleaning brush 28 is provided on the inner side of the U-shaped frame 27. The side of the U-shaped cleaning brush 28 closest to the filter element of the filter body 1 is in close contact with the filter element of the filter body 1.

[0019] In this embodiment, by setting up a filter body 1, a cleaning mechanism 2, and a monitoring mechanism 3, during use, the cleaning mechanism 2 can automatically clean the surface of the filter element of the filter body 1 in all directions, removing impurities attached to the surface of the filter element. The filter element can be cleaned without stopping the machine to disassemble the filter body 1. During the cleaning process, the filter body 1 can still complete fluid filtration normally, avoiding production interruptions caused by the need to stop the machine for traditional manual cleaning. The monitoring mechanism 3 can monitor the pressure data upstream and downstream of the filter element in real time, accurately reflecting the degree of filter element blockage through pressure changes. Moreover, when the filter element reaches a preset threshold, the cleaning operation will be automatically started and an audible and visual alarm will be issued. Thus, when the filter element is blocked, it can be detected and cleaned in time, avoiding failures such as a sudden increase in filtration resistance, abnormal system pressure, or even overload damage to the fluid delivery pump caused by the failure to deal with the filter element blockage in time, thus ensuring the stable operation of the filtration system.

[0020] Specifically, such as Figure 1 , Figure 2 , Figure 4 As shown, the monitoring mechanism 3 includes a first differential pressure sensor 31 and a second differential pressure sensor 32. The first differential pressure sensor 31 and the second differential pressure sensor 32 are respectively fixedly connected to the front side of the inlet pipe and the outlet pipe of the filter body 1. The detection heads of the first differential pressure sensor 31 and the second differential pressure sensor 32 are respectively inserted into the inlet pipe and the outlet pipe of the filter body 1.

[0021] Specifically, such as Figure 1 , Figure 2 , Figure 4 As shown, a controller 33 is fixedly connected to the top of the front side of the filter body 1, which works in conjunction with the first differential pressure sensor 31 and the second differential pressure sensor 32. The controller 33 is electrically connected to the first differential pressure sensor 31, the second differential pressure sensor 32 and the drive motor 22.

[0022] Specifically, such as Figure 1 , Figure 2 , Figure 4 As shown, an audible and visual alarm 34 is fixedly connected to the top left side of the controller 33, and the audible and visual alarm 34 is electrically connected to the controller 33.

[0023] In this embodiment: by setting a first differential pressure sensor 31, a second differential pressure sensor 32, a controller 33, and an audible and visual alarm 34, during use, the first differential pressure sensor 31 on the front side of the inlet pipe of the filter body 1 and the second differential pressure sensor 32 on the front side of the outlet pipe can monitor the pressure data upstream and downstream of the filter element in real time, and convert the pressure signal into an electrical signal and transmit it to the controller 33. After receiving the signal, the controller 33 calculates the pressure difference between the two through a built-in algorithm. When there is no blockage or only slight blockage on the surface of the filter element, the resistance of the fluid passing through the filter element is small, the pressure difference is within the preset normal range, and the device maintains normal operation. During filtration, as the filter element is used for longer periods, more impurities accumulate on its surface, increasing filtration resistance. This leads to higher inlet water pressure and relatively stable outlet water pressure. When the pressure difference exceeds a preset threshold, the controller 33 immediately sends a start command to the drive motor 22 of the cleaning mechanism 2 to initiate cleaning operations. It also controls the audible and visual alarm 34 to issue an alarm, thus enabling timely detection and cleaning of filter element blockages. This prevents sudden increases in filtration resistance, abnormal system pressure, or even overload damage to the fluid delivery pump caused by untreated filter element blockages, ensuring the stable operation of the filtration system.

[0024] Specifically, such as Figure 2 , Figure 3 As shown, the side of the transmission rod 23 closest to the inner wall of the filter body 1 and the inner wall of the gearbox 21 is rotatably connected to the inner wall of the filter body 1 and the inner wall of the gearbox 21 through sealed bearings, and the bottom of the surface of the rotating rod 26 is rotatably connected to the inner wall of the gearbox 21 through sealed bearings.

[0025] Specifically, such as Figure 2 , Figure 3 As shown, fixing strips 4 are fixedly connected to both the front and rear sides of the gearbox 21. The side of the fixing strip 4 closest to the inner wall of the filter body 1 is fixedly connected to the inner wall of the filter body 1.

[0026] In this embodiment: by setting the fixing bar 4, the gearbox 21 can be supported and fixed, thereby ensuring the stable operation of the entire cleaning mechanism 2.

[0027] Specifically, such as Figure 1 , Figure 2 As shown, the bottom of the filter body 1 is connected to a drain pipe 5, and a valve 6 is provided on the front side of the drain pipe 5.

[0028] Specifically, such as Figure 1 , Figure 2 , Figure 5 As shown, three support legs 7 are fixedly connected to the bottom of the surface of the filter body 1, and foot plates 8 are fixedly connected to the bottom of the support legs 7. Mounting holes 9 are opened on the top of the foot plates 8.

[0029] In this embodiment: by setting up a drain pipe 5 and a valve 6, impurities inside the filter body 1 can be easily discharged; by setting up three support legs 7, the filter body 1 can be stably supported; by setting up foot plates 8 and mounting holes 9, bolts can be used to install and fix it to the ground or equipment, thereby ensuring the operational stability of the device.

[0030] Working Principle: During operation, the inlet pipe of the filter body 1 continuously supplies the fluid to be filtered. After impurities are trapped by the filter element, the fluid is discharged from the outlet pipe, thus completing the normal filtration process. During this process, the pressure data upstream and downstream of the filter element can be monitored in real time by the first differential pressure sensor 31 on the front side of the inlet pipe and the second differential pressure sensor 32 on the front side of the outlet pipe. The pressure signal is converted into an electrical signal and transmitted to the controller 33. After receiving the signal, the controller 33 calculates the pressure difference between the two through a built-in algorithm. When there is no blockage or only slight blockage on the surface of the filter element, the resistance of the fluid passing through the filter element is small, and the pressure difference is within the preset normal range. The device maintains normal filtration. As the filter element is used for longer, the impurities attached to its surface gradually increase, the filtration resistance increases, the pressure in the inlet pipe rises, and the pressure in the outlet pipe remains relatively stable. When the pressure difference exceeds the preset threshold, the controller 33 immediately sends a start command to the drive motor 22 of the cleaning mechanism 2 to perform a cleaning operation. The sound and light alarm 34 is activated by the control unit, so that when the filter element is clogged, it can be detected and cleaned in time. This avoids failures such as a sudden increase in filtration resistance, abnormal system pressure, or even overload damage to the fluid transfer pump caused by the failure to deal with the filter element clog in time, thus ensuring the stable operation of the filtration system. During the cleaning operation, after receiving the command, the drive motor 22 drives the transmission rod 23 to rotate. The transmission rod 23 drives the transmission bevel gear 24 to rotate. The transmission bevel gear 24 drives the driven bevel gear 25 that meshes with it to rotate. The rotating rod 26 fixed at the top of the driven bevel gear 25 rotates accordingly. The U-shaped frame 27 at the top of the rotating rod 26 rotates synchronously around the circumference of the filter element. The U-shaped cleaning brush 28 inside the U-shaped frame 27 is in close contact with the surface of the filter element. During the rotation, it can scrape off the impurities attached to the surface of the filter element from all directions. At the same time, the operator can open the valve 6 on the drain pipe 5 at the bottom of the filter body 1, so that the scraped impurities are discharged from the drain pipe 5 with some of the fluid, thus preventing impurities from re-attaching to the filter element.

[0031] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
