Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0040] Example 1

[0041] like Figures 1 to 4 As shown, this utility model provides a filter press dewatering device, including a dewatering frame 1; guide rollers 2 are mounted on the dewatering frame 1 via an up-and-down adjustment assembly 6; guide rollers 2 and filter press rollers 3 are sequentially mounted on the dewatering frame 1 from top to bottom; a mesh belt 4 is sleeved on the outside of the guide rollers 2 and filter press rollers 3; a lower mesh belt 5 is positioned below the mesh belt 4; multiple water guide grooves 7 are provided on the opposite side walls of the dewatering frame 1; in use, sludge is added to the lower mesh belt 5, and the lower mesh belt 5 is started, causing the sludge to move to the position corresponding to the mesh belt 4 under the drive of the lower mesh belt 5. After placement; start the upper screen belt 4 (both upper screen belt 4 and lower screen belt 5 are conveyor belt structures), the filter press roller 3 can move the upper screen belt 4 closer to the lower screen belt 5 (the guide roller 2 can adjust the position of the moving upper screen belt 4, so that the sludge can be squeezed by the lower screen belt 5), so that the sludge can be squeezed by the lower screen belt 5, and the water in the sludge is squeezed out and discharged through the water guide grooves 7 on the opposite side walls of the dewatering frame 1; the sludge after water removal can be collected from the feeding end away from the sludge under the drive of the lower screen belt 5.

[0042] Example 2

[0043] Based on Example 1, such as Figures 1 to 6As shown, the guide roller 2 includes a left guide roller 21; the left guide roller 21 and the right guide roller 22 are arranged parallel to each other on the dehydration frame 1, and the axis lines of the left guide roller 21 and the right guide roller 22 are on the same horizontal plane; the up and down adjustment assembly 6 includes an adjustment seat 61, which is fixedly mounted on the dehydration frame 1; an adjustment spring 62 is vertically mounted on the top surface of the adjustment seat 61; an adjustment roller seat 63 is located at the end of the adjustment spring 62 away from the adjustment seat 61; and an adjustment roller 64 is rotatably mounted on the adjustment roller seat 63; Throttle cylinder 65 is mounted on the bottom surface of adjusting seat 61, and filter roller 3 is mounted on the piston rod of adjusting cylinder 65; filter roller 3 includes filter roller seat 31, which is mounted on the piston rod of adjusting cylinder 65; multiple filter roller bodies 32 are provided, and multiple filter roller bodies 32 are rotatably mounted on the bottom surface of filter roller seat 31, with the center lines of filter roller bodies 32 on the same horizontal plane, and mesh belt 4 is sleeved on the outside of left guide roller 21, right guide roller 22, adjusting roller 64 and filter roller body 32.

[0044] After the sludge is added to the lower mesh belt 5, the regulating cylinder 65 is activated to push the filter press roller seat 31 and multiple filter press roller bodies 32 to move closer to the lower mesh belt 5. At the same time, the regulating roller 64 also moves closer to the lower mesh belt 5 and compresses the regulating spring 62, which allows the filter press roller body 32 to smoothly push the upper mesh belt 4 to move closer to the lower mesh belt 5, thereby allowing the upper mesh belt 4 and the lower mesh belt 5 to squeeze the sludge.

[0045] The arrangement of the left guide roller 21 and the right guide roller 22 helps to maintain the overall smooth movement of the top mesh belt 4 when pushing it to move closer to the lower mesh belt 5.

[0046] After the operation is completed, the regulating cylinder 65 is activated to drive the filter press roller seat 31 and multiple filter press roller bodies 32 to move away from the lower mesh belt 5. At the same time, the regulating spring 62 is reset, causing the regulating roller 64 to move away from the lower mesh belt 5.
