At this time, the No. 1 rod 8 and the brush 9 are located in the middle hole area of ​​the filter element. If the filter element is just a simple blockage problem, then the No. 1 rod 8 drives the brush 9 to rotate together, and the impurities on the inner wall of the filter element are cleaned by the brush 9. The cleaned filter element is installed on the filter again, thereby reducing the maintenance cost of the filter; when the filter element is seriously damaged, it is only necessary to transfer a new filter element to the filter through the clamping mechanism;

[0027] In the above, the connection structure between the cylinder 2 and the workbench 1 is: the bottom of the cylinder 2 is fixed on the rotating disk 10, and the bottom of the rotating disk 10 is connected with a rotating shaft, which passes through and is rotatably set in the wall of the workbench 1, and the bottom end of the rotating shaft is connected to the output shaft of the third motor.

[0028] Preferably, the specific structure of the filter element cleaning station 6 is as follows: the filter element cleaning station 6 includes a circular sinking groove 11, and the inner diameter of the sinking groove 11 is equal to the outer diameter of the filter element, the clamping mechanism inserts the bottom of the filter element into the sinking groove 11, and the No. 1 rod 8 rotates to drive the bristles 9 to clean the inner wall of the filter element; a discharge groove 12 is opened at the bottom of the sinking groove 11 of the filter element cleaning station 6, and a plurality of discharge grooves 12 are arranged around the outer periphery of the No. 1 rod 8; a receiving plate 13 is fixedly connected to the bottom of the workbench 1, and the receiving plate 13 is arranged obliquely and located at the filter element cleaning station 6; the bottom of the workbench 1 is connected with a driving shaft for driving the No. 1 rod 8, and the bottom end of the driving shaft is connected to the output shaft of the first motor 25; when working, the first motor 25 drives the driving shaft to rotate, so that the driving shaft drives the No. 1 rod 8 to rotate, and the No. 1 rod 8 drives the bristles 9 to rotate and remove the impurities on the inner wall of the filter element, and the impurities falling on the filter element will be discharged from the discharge trough 12, and then fall on the receiving plate 13, the lower end of the receiving plate 13 is connected to the collecting trough, and the impurities on the receiving plate 13 slide along the inclined plate surface and enter the receiving trough.

[0029] Preferably, the clamping mechanism includes a support rod 14 fixedly connected to the end of the piston rod 3 connected to the cylinder 2, the support rod 14 is horizontally arranged and perpendicular to the piston rod 3, the other end of the support rod 14 is connected to a support plate 15, the bottom of the support plate 15 is symmetrically slidably connected to two sliders 16, and the bottom of each slider 16 is provided with an arc plate 18; the top of the slider 16 is slidably connected to the groove at the bottom of the support plate 15, and a double-headed threaded rod 17 is rotatably connected in the groove, and the two ends of the double-headed threaded rod 17 respectively pass through the two sliders 16, and one end of the double-headed threaded rod 17 The end is connected to the output shaft of the second motor 24; when working, when the clamping mechanism is located directly above the filter, the cylinder 2 drives the clamping mechanism to descend to the position where the two arc-shaped plates 18 can clamp the filter, and the second motor 24 drives the double-headed threaded rod 17 to rotate, so that the double-headed threaded rod 17 drives the two sliders 16 to move closer to each other, and then the two arc-shaped plates 18 clamp the outer shell or filter element on the filter. As the cylinder 2 moves upward, the outer shell or filter element rises to a certain height, and then the cylinder 2 rotates 45° or 90° to place it in the outer shell placement station 5 or the filter element cleaning station 6.

[0030] Furthermore, a clamping rod is fixedly connected to the bottom of the arc plate 18, and the top of the arc plate 18 is slidably arranged at the bottom of the slider 16, and the sliding direction of the arc plate 18 is parallel to the rod core direction of the double-headed threaded rod 17. The arc plate 18 is driven by an electric cylinder 19; the movement of the arc plate 18 is driven by the electric cylinder 19, so that the position of the arc plate 18 relative to the slider 16 changes, so that the arc plate 18 can adapt to filter elements with larger or smaller diameters, and the setting of the clamping rod also increases the clamping area between the arc plate 18 and the filter element, thereby improving the stability of the filter element clamping.

[0031] Furthermore, a pressure block 20 is fixedly connected to the bottom of the support plate 15, and the pressure block 20 is used to press the filter element located in the sinking groove 11; when the filter element is transferred to the filter element cleaning station 6 by the clamping mechanism, the two arc plates 18 release the filter element, and the support plate 15 is driven downward by the cylinder 2, so that the pressure block 20 is pressed on the top of the filter element, thereby further fixing the filter element, so that the filter element is stably located in the sinking groove 11, and when the No. 1 rod 8 drives the bristles 9 to rotate, the filter element can be prevented from falling from the sinking groove 11.

The impurities dropped from the filter element will be discharged from the discharge groove 12 and then fall on the receiving plate 13. The lower end of the receiving plate 13 is connected to the collecting groove. The impurities on the receiving plate 13 slide along the inclined plate surface and enter the receiving groove. The impurities on the inner wall of the filter element are cleaned by the brush 9. The cleaned filter element is installed on the filter again, thereby reducing the maintenance cost of the filter. When the filter element is seriously damaged, it only needs to transfer a new filter element to the filter through the clamping mechanism.

[0034] When the clamping mechanism is located directly above the filter, the cylinder 2 drives the clamping mechanism down to the position where the two arc-shaped plates 18 can clamp the filter, and the double-headed threaded rod 17 is driven to rotate by the second motor 24, so that the double-headed threaded rod 17 drives the two sliders 16 to move closer to each other, and then the two arc-shaped plates 18 clamp the outer shell or filter element on the filter. As the cylinder 2 moves upward, the outer shell or filter element rises to a certain height, and then the cylinder 2 rotates 45° or 90° to place it in the outer shell placement station 5 or the filter element cleaning station 6; the movement of the arc-shaped plate 18 is driven by the electric cylinder 19, so that the position of the arc-shaped plate 18 relative to the slider 16 changes, so that the arc-shaped plate 18 can adapt to filter elements with larger diameters or smaller diameters, and the setting of the clamping rod also makes The clamping area of ​​the arc plate 18 and the filter element is increased, which improves the stability of the filter element clamping; when the filter element is transferred to the filter element cleaning station 6 by the clamping mechanism, the two arc plates 18 loosen the filter element, and the support plate 15 is driven downward by the cylinder 2, so that the pressure block 20 is pressed on the top of the filter element, thereby further fixing the filter element, so that the filter element is stably located in the sinking groove 11, and when the No. 1 rod 8 drives the bristles 9 to rotate, the filter element can be prevented from falling from the sinking groove 11; when the pressure block 20 is pressed on the top of the filter element, after the bristles 9 have cleaned the impurities on the inner wall of the filter element, the air pump 22 works to make the cavity continuously eject jets through the exhaust hole 21, which, on the one hand, blows away the impurities on the bristles 9, and on the other hand, blows away the impurities at the bottom of the sinking groove 11 from the discharge groove 12, thereby completing the cleaning of the filter element.
