For the purpose of achieving the above objectives, the technical means and its efficacy, the following examples are given, and the drawings are as follows:

First of all, please refer to the third, fourth, seventh and ninth drawings. The main structure and principle of the created sludge filter press are basically the same as those of the conventional users. As shown in the figure, the sludge filter press is a rectangular body. The frame 1 has a plurality of controlled forwards (such as the right side in the third figure) on the opposite sides of the rails 11 and is overlapped and supported by the frame 2, and is provided with a fixed end seat 12 and a movable end seat. 13. The hydraulic cylinder 14 is forced to be positioned by the piston rod 141. In each of the frame frames 2, two side lugs 24 are disposed on the two side rails 11, and the concave filter chambers 21 on both sides of each of the plate frames 2 are respectively provided with a filter cloth 22 communicating with the sludge opening 23, and a corner thereof. The position is provided with a plurality of drainage holes 25 for connecting the sludge slurry line 17 and the sewage discharge line 18 of the fixed end seat 12, and the frame 1 is provided with a longitudinally extending conveyor belt 15 and a discharge tank below each of the frame frames 2. 16.

A pulling mechanism 3 is disposed on each of the two opposite rails 11 of the frame 1 of the sludge filter press. As shown in the third to sixth figures, the two pulling mechanisms 3 each include a common sprocket 31 and 32. A chain 33 is attached to the ring to connect a clamp 34 and its two side guide wheels 38, and is reciprocally displaced back and forth along the guide rail 111. A clamp hook 35 and a clamp hook 36 are normally arranged in the clamp 34, and the hook 35 and the clamp hook 36 can be retracted by each of the clamps, so that the two clamps 34 and their hooks 35 and clamps are hooked. 36 controlled backwards (as shown in the left side of the seventh to tenth drawings) pulls the frame 2 one by one, and when the brake lever 37 reaches the foremost end of the track 11 with the clamp 34, it can control the hook 35 to retreat Positioning is facilitated so that the clamp 34 moves back toward the rear end with the chain 33.

When the sludge filter press drives all the frame 2 to overlap and presses the sludge according to the third and fourth figures, the pump (not shown) continuously feeds and squeezes the sludge to make the sewage pass through the drainage. The hole 25 is discharged outward, and the sludge 41 (refer to the ninth figure) is wrapped in the filter chamber 21 by the filter cloth 22 to be squeezed and dehydrated into a mud cake 4, and then the two clamps 34 of the two pulling mechanisms 3 are collectively rearward. Pulling the frame 2 one by one, as shown in the seventh to ninth drawings, the dewatered mud cake 4 is discharged downward from between the two frame frames 2 and the filter cloth 22, so that the mud cake 4 is dropped on the conveyor belt 15 on.

The present cutting device 5 is mainly used for cutting off the mud cake 4 discharged from the sludge filter press. As shown in the fourth to ninth views, the cutting device 5 includes a rod 51 extending the cutting rod 51 laterally to each frame. 2 below the displacement path, and the cutting rod 51 is located between the plate frame 2 and the conveyor belt 15, and a connecting portion 52 is extended upward at one end or opposite ends of the cutting rod 51, and is fixed by one end or both end connecting portions 52. In the clamp 34 or the chain 33 of the relative pulling mechanism 3, the cutting rod 51 and the opposing clamp 34 are controlled to be longitudinally reciprocally displaced. Therefore, the present cutting device 5 can synchronously drive the cutting rod 51 by the pulling mechanism 3 to automatically cut off the mud cake 4, and the broken mud cake 4 is all dropped on the conveyor belt 15, so that the frame frames 2 can be prevented from each other. The mud slag is clamped behind to ensure the dewatering effect of the sludge 41, and the use efficiency is improved, and the cutting device 5 is simple and convenient to operate, and is used for a long time.

Referring to the fourth to ninth drawings, the cutting device 5 is provided with a plurality of opposing holes 54 at the one end or the opposite ends of the cutting rod 51 and the connecting portion 52 thereof (see the fourth figure), and the locking plurality of corresponding bolts 56 are fixedly mounted, and A cutting edge 53 may be provided at the leading edge of the cutting rod 51 to facilitate cutting off the mud cake 4. In addition to this, as shown in Fig. 14, a sharp knife 55 protruding forward may be provided at the front edge of the cutting rod 51 to make it easier to pierce the cut cake 4.

When the sludge filter press is operated in conjunction with the electric control box, as shown in the third figure, the frame frames 2 on the rails 11 on both sides of the frame 1 are controlled to face forward (as shown in the right side of the figure). Dehydration is performed by extruding the sludge slurry, and then the movable end seat 13 is displaced rearward by the hydraulic cylinder 14, and is clamped by the clamp 34 by the pulling mechanism 3 on the side of the two rails 11 as shown in the seventh to ninth views. The lug 24 of the first plate frame 2, and the first plate frame 2 is pulled back to remove the dewatered first mud cake 4 from the two frame frames 2, so that the mud cake 4 bottom The tip is first dropped on the conveyor belt 15, and if the mudcake 4 does not rupture itself (see Figures 8 and 9), it is placed on the conveyor belt 15 and between the frame 2. At this time, the clamp 34 of the pulling mechanism 3 is again displaced forward to prepare to clamp the second frame 2, as shown in the tenth and eleventh views, the cutting rod 51 of the cutting device 5 is first cut off and broken the mud cake 4, so that After the mud cake 4 is broken, it is all dropped on the conveyor belt 15. Then, the two pulling mechanism 3 clamps the lug 24 of the second plate frame 2 with the clamp 34, and then pulls the second plate frame 2 backward to remove the dehydrated from the two frame frames 2 downward. The second mud cake 4, and if the second mud cake 4 does not rupture itself (see Figure 12), it will stand on the conveyor belt 15 and between the frame 2. At this time, the jig 34 of the pulling mechanism 3 is again displaced forward to prepare to clamp the third plate frame 2, as shown in the thirteenth figure. It is shown that the cutting rod 51 of the cutting device 5 is first cut off to break the second mud cake 4, so that the second mud cake 4 is completely ruptured and then dropped on the conveyor belt 15; then continue to operate in the above manner, one by one. Open all the frame 2, and remove the mud cake 4 downwards to cut off, and then complete the sludge pressure filtration dewatering and unloading operation.

In summary, the present invention can solve the deficiency and lack of the conventional sludge filter press. The key technology is to use the pulling mechanism 3 to synchronously drive the cutting rod 51, which can automatically cut off the mud cake 4, and the broken mud cake 4 Falling on the conveyor belt 15 can prevent the respective frame frames 2 from sandwiching the mud slag between each other to ensure the pressure filtration dewatering effect of the sludge 41, improving the use efficiency, and the cutting device 5 is simple and convenient to operate, and more durable. Durable, 提出Proposed new patent applications in accordance with the law.
