Description

Technical Field

[0001] The utility model relates to the technical field of filter presses, in particular to a filter plate assembly for a filter press. Background Art

[0002] A filter press is a device mainly used for solid-liquid separation of settled sludge filtrate. The filter press mainly includes a frame, a filter frame installed on the frame, and a hydraulic system installed on the frame. The filter frame is slidably connected to the frame. A filter plate and a filter cloth are fixed on the filter frame. The filter cloth is detachably connected to the filter plate. Grouting holes are provided on the filter plate. When the frame injects the filtrate into the grouting holes, the filtrate adheres to the filter cloth of the filter plate. When the hydraulic system squeezes the filter frame, the liquid and solid in the filtrate are separated, thereby obtaining a dischargeable water body.

[0003] Existing public patent: CN202320188027.2 A filter plate assembly for a filter press, by adopting the above technical solution, when installing the filter cloth, by inserting the clamping cloth piece into the plug-in groove, and then driving the clamping block to be plugged into the plug-in groove, the clamping cloth piece can be pressed; when disassembling, by grasping the clamping block, the clamping block can be driven to detach from the plug-in groove. The disassembly and installation steps are relatively simple, and it is convenient to disassemble and install the filter cloth. However, in this comparative example, the installation and disassembly process of the filter cloth is still relatively cumbersome. The fixation of one filter cloth requires driving four groups of clamping blocks to be plugged into the plug-in groove. This process is relatively cumbersome, and it is not convenient to replace the filter cloth, which makes the practicality of the filter plate assembly weaker. Utility Model Content

[0035] The outer surface of the filter plate body 1 is slidably sleeved with a mounting frame 3;

[0036] Among them, a filter cloth fixing mechanism is arranged on the installation frame 3, and the filter cloth fixing mechanism includes a positioning block 6, a diversion hole 7, a protrusion 8, a connecting platform, a first fixing groove 10, a fixing block 11, a fixing spring 12, a positioning plate 4 and a second fixing groove 5.

[0038] Among them, two first fixing grooves 10 are provided on the left and right outer surfaces of the installation frame 3;

[0039] The two first fixing grooves 10 are communicated with the interior of the installation frame 3 .

[0040] Furthermore, the two fixing blocks 11 are slidably connected in the two first fixing grooves 10;

[0041] Wherein, the adjacent outer surfaces of the two fixing blocks 11 both extend into the installation frame 3;

[0042] The adjacent outer surfaces of the two fixing blocks 11 extend into the two second fixing grooves 5 through the two first fixing grooves 10 , and the two fixing blocks 11 are slidably connected to the two second fixing grooves 5 .

[0043] Furthermore, the two positioning plates 4 are fixedly connected to the two opposite side surfaces of the two fixing blocks 11;

[0044] Among them, four fixing springs 12 are fixedly connected to the adjacent two side surfaces of the two positioning plates 4;

[0045] Among them, adjacent ends of the four fixing springs 12 are fixedly connected to the left and right outer surfaces of the filter plate body 1 .

[0046] Furthermore, two positioning blocks 6 are fixedly connected to the bottom wall of the filter tank 2;

[0047] Among them, two diversion holes 7 are opened on the upper surfaces of the two positioning blocks 6, and the two diversion holes 7 extend downward from the lower surface of the filter plate body 1;

[0048] Wherein, a plurality of protrusions 8 are fixedly connected to the bottom wall of the filter tank 2;

[0049] Among them, a plurality of connecting platforms 9 are fixedly connected to the bottom wall of the filter tank 2, and the connecting platforms 9 are in the shape of a truncated cone.

[0050] When the filter cloth is in the air, it is necessary to tighten the filter cloth 11 so that the filter cloth 12 can be tightened.

[0051] Following the above, in the process of vertically sliding the mounting frame 3 from top to bottom on the outer surface of the filter plate body 1, when the lower surface of the mounting frame 3 is in the same plane as the lower surface of the filter plate body 1, release the pulling of the two positioning plates 4, and under the action of the released elastic force of the fixing spring 12, push the two fixing blocks 11 to slide into the second fixing groove 5, thereby fixing the filter plate body 1 and the mounting frame 3, so that the filter plate body 1 and the mounting frame 3 cannot be separated from each other, thereby fixing the filter cloth, and disassembly only requires pulling the two positioning plates 4 and then moving the mounting frame 3 upwards, which is convenient for disassembly and assembly, and thus convenient for replacing the filter cloth, thereby increasing the practicality of the filter plate assembly.

[0052] Furthermore, in this solution, the protrusion 8 and the connecting platform 9 can increase the squeezing of the filter cloth and increase the drainage area during filter pressing, thereby ensuring that the filter cloth can be fully squeezed, thereby improving the efficiency of solid-liquid separation.

[0053] Furthermore, in this solution, the positioning block 6 and the diversion hole 7 can increase the drainage speed, thereby improving the efficiency of solid-liquid separation.

[0054] Working principle: When the device is in use, the gap between the filter plate body 1 and the mounting frame 3 is wider. When in use, first place the filter cloth slightly larger than the filter plate body 1 on the upper surface of the filter plate body 1, and press the center of the filter cloth slightly downward to fit with the upper surface of the connecting platform 9, the protrusion 8, etc. At this time, pull out the two positioning plates 4, so that the two positioning plates 4 move back to back. In this process, the fixing spring 12 is stretched, so that the fixing spring 12 is stretched, and the two fixing blocks 11 are also synchronously driven to move back to back in this process. When the two fixing blocks 11 move out of the mounting frame 3, the mounting frame 3 is vertically slid from top to bottom on the outer surface of the filter plate body 1. In this process, the corners of the filter cloth larger than the filter plate body 1 will also be squeezed into the gap between the filter plate body 1 and the mounting frame 3, thereby fixing the filter cloth. This fixing method is convenient and fast, and thus it is easy to replace the filter cloth, and the operation is simple, thereby increasing the practicality of the filter plate assembly.

[0055] Following the above, in the process of vertically sliding the mounting frame 3 from top to bottom on the outer surface of the filter plate body 1, when the lower surface of the mounting frame 3 is in the same plane as the lower surface of the filter plate body 1, release the pulling of the two positioning plates 4, and under the action of the released elastic force of the fixing spring 12, push the two fixing blocks 11 to slide into the second fixing groove 5, thereby fixing the filter plate body 1 and the mounting frame 3, so that the filter plate body 1 and the mounting frame 3 cannot be separated from each other, thereby fixing the filter cloth, and disassembly only requires pulling the two positioning plates 4 and then moving the mounting frame 3 upwards, which is convenient for disassembly and assembly, and thus convenient for replacing the filter cloth, thereby increasing the practicality of the filter plate assembly.
