[0026] Example 1: As Figures 1 to 4 shown, a simple filter device that is convenient for replacement includes a filter frame body 5, a filter element 2, a rotating support rod 3, and an actuator 4.
[0027] The filter frame body 5 includes a rectangular grid frame and vertical bearing strips extending from the left and right edges on the upper and lower sides of the rectangular grid frame. The rotating support rod 3 includes a main rotating support rod and a driven rotating support rod. One end of the filter element 2 is fixedly arranged on the outer periphery of the main rotating support rod, and the other end is fixedly and wound around the outer periphery of the driven rotating support rod 3. The rotating support rod 3 is detachably and rotatably arranged on the bearing strip, and the actuator 4 is arranged on one side of the main rotating support rod for driving the rotating support rod 3 to rotate.
[0028] The width of the filter element 2 is greater than the width of the rectangular grid frame of the filter frame 5, and the width of the filter element 2 is less than the length of the rotating support rod 3.
[0029] In this embodiment, the filtering material of the filter element is selected according to the specific use environment to meet the requirements of the appropriate composite filtering grade.
[0030] There are multiple grids inside the rectangular grid frame, which play a role in supporting the filter element. There are a total of four load-bearing bars on the filter frame body 5, with two arranged on the upper and lower sides respectively. The load-bearing bars are in strip shape, and each load-bearing bar is provided with a movable buckle 6 for the installation and disassembly of the rotating support rod 3. In this embodiment, the movable buckle 6 is U-shaped, and the U-shaped movable buckle 6 is fixed at the corresponding position of the front end of the load-bearing bar, and the upper and lower two movable buckles 6 are located on the same horizontal line. The two ends of the active rotating support rod are rotatably arranged in the movable buckles 6 of the lower two load-bearing bars, and the two ends of the driven rotating support rod are rotatably arranged in the movable buckles 6 of the upper two load-bearing bars.
[0031] A filter screen 7 is provided at the front end of the rectangular grid frame. The size of the filter screen 7 is adapted to the size of the rectangular grid frame of the filter frame body 5. The filter screen 7 is arranged on the rectangular grid frame in the form of a pressed net, a welded grid or other types of safety net forms.
[0032] A support base 8 is arranged on one side of the active rotating support rod. The support base 8 is used to support the actuator 4. The actuator 4 includes an electrically connected motor and a controller. Preferably, the controller is also electrically connected to a limit switch, and the controller controls the rotation of the motor by controlling the limit switch. Specifically, during implementation, the number of turns of the motor's single operation is set according to the length of the filter screen 7. After reaching the required replacement length, the limit switch works, and the controller controls the motor to stop rotating, and then the active rotating support rod automatically stops rotating. Further, the controller is connected to a PLC device, and the PLC device is used to set a timed replacement mode to achieve the timed replacement of the filter element 2. Among them, a timer module is provided in the PLC device, and the time for replacing the filter element 2 is set according to the actual working conditions. The PLC device adopts the existing technology and will not be elaborated here. In addition, when the PLC device fails and the filter element 2 needs to be replaced, the controller is manually controlled to work to achieve the timed replacement of the filter element 2.
[0033] Inside the support base 8, the main shaft 9 of the actuator is detachably connected to the active rotating support rod through a docking rod 10, and other various connection methods can also be used to achieve this.
[0034] As Figure 5 shown, the filter frame body 5 is installed at the air duct connection port 1 on the filter air duct.
[0035] Usage process: Install the present utility model at the air inlet of the fan. When the fan is running, the air flow passes through the filter element 2 and the filter screen 7 in sequence. When the filter element 2 needs to be replaced, the actuator 4 rotates to drive the rotation on the active rotary support rod, winding the used filter element around the active rotary support rod, while the driven rotary support rod unwinds the unused filter element 2. When all the filter elements covering the filter screen 7 are the unused parts, that is, the required replacement length, the limit switch of the actuator 4 works, and the active rotary support rod stops rotating, completing the replacement of a filter element. With this device, the operator can complete the replacement of the filter element without stopping the machine.
[0036] Contents not elaborated in detail in the present utility model are all prior arts and are well-known to those skilled in the art.
[0037] It should be noted that the above embodiments are only used to illustrate the present utility model, but the present utility model is not limited to the above embodiments. Any simple modification, equivalent change and modification made to the above embodiments based on the technical essence of the present utility model all fall within the protection scope of the present utility model.
