Description

Technical Field

[0001] This utility model relates to the field of filter press technology, and in particular to a filter plate pull lug for a filter press. Background Technology

[0002] During operation, plate and frame filter presses frequently experience wear on the filter plate tracks. The plastic pull tabs on both sides of the filter plates rest on stainless steel tracks. Due to the weight and friction of the stainless steel tracks themselves, wear between the pull tabs and the tracks cannot be completely prevented. This results in continuous debris generation on the stainless steel tracks, which can easily enter the produced products inside the equipment, affecting product quality. Furthermore, as the plate-pulling trolley moves along the filter plate tracks, it contacts the pull tabs to slide the filter plates. Wear occurs at the contact points between the trolley and the pull tabs, leading to debris generation and even damage to the pull tabs. Therefore, improvements to the traditional pull tab design are needed to address these technical challenges. Utility Model Content

[0018] Reference Figures 1 to 3As shown, a filter plate pull lug for a filter press includes a pull lug body 1, a roller 2, and a U-shaped protective plate 3. One side of the pull lug body 1 has a connecting block 11 for detachable connection with the filter plate, and the other side has an ear portion 15 for contacting with a plate-pulling trolley. The roller 2 is rotatably connected to the bottom of the pull lug body 1, and the roller 1 is located on one side of the connecting block 11. The U-shaped protective plate 3 is fixedly connected to both sides of the ear portion 15. This invention changes the connection between the pull lug body 1 and the track from a sliding connection to a rolling connection, and adds a U-shaped protective plate to the contact area between the pull lug body 1 and the plate-pulling trolley to solve the problem of easy wear and tear during use and improve service life.

[0019] The pull-ear body 1 includes an integrally formed connecting block 11, a diagonal brace 12, a horizontal brace 13, a vertical brace 14, and an ear portion 15. The connecting block 11 and the vertical brace 14 are arranged parallel to each other at intervals. One end of the diagonal brace 12 and the horizontal brace 13 is fixedly connected to one side of the connecting block, and the other end of the diagonal brace 12 and the horizontal brace 13 is fixedly connected to one side of the vertical brace 14. The connecting block 11, the diagonal brace 12, the horizontal brace 13, and the vertical brace 15 are all integrally formed. 14 form an equiangular trapezoidal structure; the diagonal brace 12 is the hypotenuse of the equiangular trapezoid; the horizontal brace 13 is the right-angled side of the equiangular trapezoid and is located at the bottom of the pull lug body 1; the lug 15 is fixedly connected to the other side of the vertical brace 14; the two ends of the connecting block 11 extend outward from the equiangular trapezoidal structure along the length direction, and the connecting block 11 is provided with a plurality of connecting holes 111 spaced apart from top to bottom; the roller 2 is rotatably connected to the horizontal brace 13. Specifically, the bottom surface of the horizontal brace 13 is provided with a recess 131 on the side near the connecting block 11, and the roller 2 rotates within the recess 131. The connecting block 11 has a rotating shaft hole 112 that extends horizontally through the recess; the roller 2 has a coaxially through central shaft hole, and a rotating shaft 4 is rotatably connected inside the rotating shaft hole.
