[0022] Working principle:

[0023] The filter element is fixedly nested on the centering shaft 8, and the lifting plate 4 is raised by extending the hydraulic cylinder 3. The lifting plate 4 pushes the conical pressure ring 6 to rise through the lifting rod 5, and the annular cone surface of the conical pressure ring 6 pushes the closing slider 7 to slide along the linear slide rail 101 toward the centering shaft 8. At the same time, the vertical plate 41 rises with the lifting plate 4, and the guide slider 42 slides with the cam ring groove 82 of the centering shaft 8 when it rises, so that the centering shaft 8 automatically rotates a certain angle. When the guide slider 42 moves to the top of the cam ring groove 82, the centering shaft 8 no longer rotates. At this time, the closing slider 7 does not squeeze and close the filter element; the hydraulic cylinder 3 continues to drive the lifting plate 4 to rise, and the conical pressure ring 6 rises and continues to push the closing slider 7 to slide toward the centering shaft 8 to squeeze and close the filter element, and the vertical plate 41 overcomes the spring 4 3 continues to slide upward; when the closing slide block 7 closes the filter element for the first time, the hydraulic cylinder 3 contracts to make the lifting plate 4 descend, and the lifting plate 4 descends to pull the conical pressure ring 6 down. When the conical pressure ring 6 descends, it pulls the limiting slide block 71 through its limiting slide groove 61 to make the closing slide block 7 away from the centering shaft 8, and at the same time, the vertical plate 41 descends together with the lifting plate 4, and the guide slide block 42 descends and slides with the cam ring groove 82 to make the centering shaft 8 automatically rotate a certain angle; according to the rising method, the filter element is extruded and closed for multiple times, and the filter element is extruded and closed for each time. The circumferential position of the filter element is adjusted as the centering shaft 8 rotates until the filter element is completed after one circle of rotation. The filter element is closed evenly, the closing effect is good, the structure is simple, and the closing efficiency of the filter element is high.

[0024] The closing device for filter element processing disclosed in the present embodiment pushes the closing slider 7 to slide toward the centering shaft 8 through the conical pressure ring 6 to perform multiple extrusion and closing processing on the filter element. The guide slider 42 provided on the lifting plate 4 slides with the cam ring groove 82 on the centering shaft 8, so that the circumferential position of the filter element can be adjusted as the centering shaft 8 rotates each time the filter element is extruded and closed. The filter element is closed evenly, the closing processing effect is good, the structure is simple, the processing cost is low, the operation is stable, and the filter element closing processing efficiency is high.
