[0027] like Figure 1-2 As shown, the utility model discloses an automatic winding primary filter, comprising a support frame 1, an upper filter material box 2 arranged at the upper end of the support frame 1, a lower filter material box 3 arranged at the lower end of the support frame 1, and a fixing plate 4 arranged between the upper filter material box 2 and the lower filter material box 3, a filter material guide rod is arranged between the support frames 1, and a pressure difference sensor 9 is arranged on one side wall of the support frame 1.

[0028] A driven filter material roller 21 is arranged inside the upper filter material box 2, and a box door 22 is opened at the bottom. One side of the bottom of the upper filter material box 2 is connected to the box door 22 by a hinge 24, and a handle 23 is provided on the box door 22. The other side of the bottom of the upper filter material box 2 is fixed to the box door 22 by a latch 25; a plurality of roller mechanisms 8 are arranged at the upper end of the fixed plate 4. When a new filter material roller is installed, the box door 22 is opened, and the new filter material roller is supported to a suitable position by the roller mechanism 8, which facilitates installation and improves safety; the roller mechanism 8 includes a hydraulic telescopic rod 81 and an arc plate 82. The arc plate 82 is arranged at the top end of the hydraulic telescopic rod 81, and the bottom end of the hydraulic telescopic rod 81 is connected to the fixed plate 4. The upper end of the arc plate 82 is provided with an anti-slip layer to further improve safety.

[0029] An active filter material roller 31 and a cleaning mechanism 32 are provided in the lower filter material box 3. The cleaning mechanism 32 is provided directly below the active filter material roller 31. A control box 5 and a motor 6 are provided above the lower filter material box 3. The output shaft of the motor 6 is connected to the active filter material roller 31 through a belt 7. The cleaning mechanism 32 includes an exhaust head 321, a pipeline 322 and a dust box 323. The exhaust head 321 is connected to the dust box 323 through the pipeline 322. An exhaust fan 324 is provided at the front end of the exhaust head 321.

[0030] The pressure difference sensor 9, the motor 6, the hydraulic telescopic rod 81 and the exhaust fan 324 are all electrically connected to the controller.

[0031] Working principle: When in use, first install the driven filter material roller 21 in the upper filter material box 2 through the roller mechanism 8, pull one end of it, and fix it to the active filter material roller 31 after unfolding the filter surface on the support frame 1 through the filter material guide rod. When the dust-laden air passes through the filter, the resistance of the filter will gradually increase. After reaching a certain level, the pressure difference sensor 9 transmits the signal to the controller, and the controller controls the motor 6 to start. At this time, the motor 6 drives the active filter material roller 31 to rotate, rolls up the dirty filter material, and drives the driven filter material roller 21 to rotate at the same time, and replaces the filter surface with clean filter material. During the winding process, the cleaning mechanism 32 is started to clean the dirty filter material.

[0032] Therefore, the utility model adopts an automatic winding primary filter with the above structure, which avoids the safety problems caused to the workers due to the high-altitude operation when installing new filter materials, and can also clean the dirty filter materials, reducing the work intensity of the workers and improving the cleaning efficiency.
