[0025] The present invention will be described in detail below with reference to the accompanying drawings and in combination with embodiments.

[0026] Example

[0027] like Figure 1 、 Figure 2 and Figure 3As shown, an improved filter press filter plate structure includes a filter plate body 1, and a movable positioning device 2 is provided on the side of the filter plate body 1. The movable positioning device 2 includes a fixed frame 21 fixedly connected to the filter plate body 1, and a ball 22 rotatably connected to the fixed frame 21. A movable frame 23 that can move horizontally along the fixed frame 21 is provided on the side of the fixed frame 21 away from the filter plate body 1. One end of the movable rod 231 on the movable frame 23 passes through the fixed frame 21 and is fastened to the limit plate 24. An elastic member is connected between the movable rod 231 and the fixed frame 21. A tightening screw 25 is rotatably connected to the limit plate 24. The other end of the tightening screw 25 passes through the fixed frame 21 and the movable frame 23 in sequence, and the tightening screw 25 is fastened to the fixed frame 21 through two locking nuts 26. With this structure, a movable positioning mechanism composed of a fixing frame 21, a ball 22, a tightening screw 25 and a limit plate 24 is provided. That is, when a user uses the ultra-high pressure filter press to operate, the user can allow the filter plate body 1 to slide on the surface of the filter press equipment, which is convenient for the user to install and place the filter plate body 1. At the same time, the user can move the filter plate and then fix it to avoid the filter plate body 1 from accidentally falling during use.

[0028] like Figure 1 、 Figure 2 As shown, two locking nuts 26 are respectively distributed one in front and one behind on both sides of the tightening screw 25 located on the fixing frame 21. With this structure, the limit plate 24 can be tightly pressed against the surface of the filter press equipment to prevent the filter plate body 1 from accidentally falling during use.

[0029] like Figure 1 、 Figure 2 As shown, the elastic member is a transverse spring 27, which is sleeved on the outside of the movable rod 231. One end of the transverse spring 27 is tightly connected to the outer wall of the fixed frame 21, and the other end of the transverse spring 27 is fixedly connected to the inner side of the movable frame 23. With this structure, when the two locking nuts 26 are loosened, the transverse spring 27 can quickly move the movable frame 23 toward the surface of the filter press equipment, facilitating the rapid installation of the moved filter plate.

[0030] like Figure 1 、 Figure 2 As shown, through holes are provided on the fixed frame 21 and the movable frame 23 for the tightening screw 25 to pass through, and a limit block 251 is provided at the portion of the tightening screw 25 exposed from the movable frame 23. With this structure, the provision of the limit block 251 can prevent the tightening screw 25 from falling off from one end of the movable frame 23, facilitating the pulling out of the tightening screw 25.

[0031] like Figure 1As shown, there are two movable positioning devices 2, which are symmetrically arranged on both sides of the filter plate body 1. This structure is conducive to more firmly fixing the moved filter plate.

[0032] like Figure 3 As shown, the upper end of the fixing frame 21 defines a mounting cavity 31, within which an inner movable block 32 is movably disposed. There are at least two balls 22, each of which is movably embedded in the lower end of the inner movable block 32. A longitudinal threaded post 33 is rotatably connected to the upper end of the inner movable block 32. The other end of the longitudinal threaded post 33 is threadedly connected to the fixing frame 21. The top of the fixing frame 21 defines an internal threaded hole that mates with the external thread of the longitudinal threaded post 33. Two longitudinal springs 34 are connected between the upper end surface of the inner movable block 32 and the upper end surface of the mounting cavity 31. The longitudinal threaded post 33 and the longitudinal springs 34 are both two in number and symmetrically arranged. This structure, by designing the inner movable block 32, the longitudinal threaded post 33, and the longitudinal springs 34, overcomes the problem of wear between the existing fixing frame 21 and the surface of the filter press after long-term sliding use, which causes the gap between the fixing frame 21 and the surface of the filter press to gradually increase, thereby reducing the guiding accuracy of the filter plates.

[0033] like Figure 1 、 Figure 3 As shown, the portion of the longitudinal threaded column 33 exposed from the fixing frame 21 is fastened with a rotation knob 331. With this structure, the design of the rotation knob 331 facilitates the rotation of the longitudinal threaded column 33.

[0034] like Figure 1 As shown, a handle 11 is provided on the surface of the filter plate body 1; the handle 11 is made of plastic. With this structure, by providing the plastic handle 11, the user can hold the handle 11 and place the filter plate body 1 on the surface of the filter press equipment. The handle 11 made of plastic is lighter, making it easier for the user to pick up and place the filter plate.

[0035] like Figure 1 As shown, a rubber pad 241 is provided on the side of the stop plate 24 away from the tightening screw 25. The rubber pad 241 is provided with diamond-shaped anti-slip patterns. This structure, i.e., the rubber pad 241 and the diamond-shaped anti-slip patterns on the stop plate 24, increases friction with the surface of the filter press equipment, effectively securing the filter plate after movement.

[0036] During use, when the user uses the ultra-high pressure filter press to operate, the user holds the handle 11 to place the filter plate body 1 on the surface of the filter press equipment. The user can slide the filter plate body 1 on the surface of the filter press equipment through the pulley provided on the fixing frame 21, which is convenient for the user to place and install the filter plate body 1. When the movement is completed, the user loosens the two locking nuts 26. Under the action of the transverse spring 27, the limit plate 24 will move toward the surface of the filter press equipment and abut against the surface of the filter press equipment. Finally, the two locking nuts 26 are tightened in reverse to complete the fixation of the moved filter plate.

[0037] If the gap between the fixing frame 21 and the surface of the filter press equipment is large, the rotating knobs 331 on both sides of the upper end of the fixing frame 21 are rotated to drive the longitudinal threaded column 33 at the lower end to move downward. An internal threaded hole is provided on both sides of the top of the fixing frame 21, and the internal threaded hole and the external thread on the surface of the longitudinal threaded column 33 are rotated to cooperate with each other, so that the rotation of the longitudinal threaded column 33 can press the entire inner movable block 32 downward, and the entire inner movable block 32 drives the ball 22 at the lower end to press downward. Through this operation, the surface of the ball 22 and the surface of the filter press equipment are rolled and fitted.

[0038] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
