[0033] Example 1

[0034] like Figure 1-4 As shown, the sludge thickening device proposed in this utility model includes an adjusting rod 5, a thickening tank, a push plate, and a discharge assembly;

[0035] The adjusting rod 5 is rotatably installed in the concentration tank, and both ends extend to the outside of the end of the concentration tank. One end of the adjusting rod 5 is provided with a motor 4 for driving the adjusting rod 5 to rotate in the concentration tank during use. The motor 4 can be fixed by external equipment such as a support stool or steel frame during use (not shown in the prior art diagram), and the output shaft of the motor 4 is arranged coaxially with the adjusting rod 5.

[0036] There are two push plates. The two push plates are installed on the inner end of the thickening tank and sleeved on the outside of the adjusting rod 5. The side of the push plate is provided with a filter plate for filtering sludge in use.

[0037] The discharge assembly is located at the bottom center of the concentration tank.

[0038] In this embodiment, sludge is injected into the middle of the thickening tank, and the motor 4 drives the adjusting rod 5 to rotate, causing the adjusting rod 5 to move two push plates towards each other. At the same time, the two push plates drive the filter plates to move, so that the push plates and filter plates squeeze the sludge and filter the water in the sludge through the filter plates to the inner ends of the thickening tank. The sludge is compressed into semi-solid or solid sludge blocks. By opening the discharge assembly, the sludge is automatically discharged from the inside of the tank 1 to the bottom of the tank 1 by its own gravity, which improves the sludge treatment efficiency.

[0039] Example 2

[0040] like Figure 1-3 As shown, the sludge thickening device proposed in this utility model differs from that in Embodiment 1 in that the thickening tank includes a tank body 1, bolts 2, cover plate 3, feed pipe 6, and drain pipe 8.

[0041] The middle part of the box 1 has a cavity with openings at both ends, and both ends have flanges, and the bottom end has a discharge port;

[0042] There are two cover plates 3. Both cover plates 3 are installed at one end of the housing 1 by bolts 2 and are rotatably connected to the adjusting rod 5 by bearings.

[0043] The feed pipe 6 is located at the top center of the box 1 and is connected to the box 1;

[0044] There are two drain pipes 8, which are respectively located on one side of the bottom of the box 1 and connected to the box 1. Both the feed pipe 6 and the drain pipe 8 have valves (not shown in the figure) to control the conveying of sludge and filtered water.

[0045] In this embodiment, the cover plate 3 is connected to the box body 1 by bolts 2, and the adjusting rod 5 is rotatably connected to the cover plate 3 by bearings, so that the cover plate 3 is detachably connected to the box body 1 and the adjusting rod 5, so that the filter plate can be cleaned or replaced. At the same time, the sludge is transported to the middle of the box body 1 through the feed pipe 6, and the water filtered by one filter plate is discharged through two drain pipes 8 respectively.

[0046] Example 3

[0047] like Figure 3-4 As shown, the sludge thickening device proposed in this utility model differs from the first embodiment in that the pusher plate includes a grid plate 13 and a sleeve 14.

[0048] The sleeve 14 is fitted onto the outside of the adjusting rod 5;

[0049] The grating plate 13 is installed on the outside of the sleeve 14 and is slidably connected to the inside of the box 1.

[0050] In an optional embodiment, both ends of the adjusting rod 5 and the inner side of the housing 1 are provided with threads, and the threads at both ends of the adjusting rod 5 are arranged symmetrically with respect to the center of the housing 1. When the adjusting rod 5 is installed in conjunction with the sleeve 14, the threads of the adjusting rod 5 are accommodated in the sleeve 14.

[0051] In this embodiment, the adjusting rod 5 is provided with symmetrical threads on the outside, so that the rotation of the adjusting rod 5 drives the two grid plates 13 to move towards the middle of the box 1 through the sleeve 14, and the grid plates 13 drive the filter plate to move synchronously, so that the sludge is squeezed by the two grid plates 13 and the water is separated by the action of the filter plate.

[0052] Example 4

[0053] like Figure 3-4 As shown, the sludge thickening device proposed in this utility model differs from the first embodiment in that the filter plate includes a filter cloth 11 and a perforated plate 12.

[0054] The perforated plate 12 is fitted onto the outside of the sleeve 14 and connected to the grid plate 13;

[0055] The filter cloth 11 is disposed on the side of the perforated plate 12.

[0056] In this embodiment, the perforated plate 12 is connected to the grid plate 13, and the filter cloth 11 is installed on the side of the perforated plate 12 so that the perforated plate 12 supports the filter cloth 11 and prevents the filter cloth 11 from being deformed or damaged due to pressure.

[0057] Example 5

[0058] like Figure 2-3 As shown, the sludge thickening device proposed in this utility model differs from the first embodiment in that the discharge assembly includes a baffle 7, a rotating seat 9, and a hydraulic cylinder 10.

[0059] The baffle 7 is mounted on the bottom of the housing 1 via a hinge;

[0060] There are two rotating seats 9, which are respectively installed at the bottom of the baffle 7 and the box 1;

[0061] The hydraulic cylinder 10 is installed between the two rotating seats 9.

[0062] In an optional embodiment, the cross-sectional projection of the baffle 7 is T-shaped, and the top of the baffle 7 is inserted into the discharge port at the bottom of the box 1, with the top of the baffle 7 flush with the inner bottom of the box 1.

[0063] In this embodiment, the hydraulic cylinder 10 extends and retracts, and the baffle 7 is connected to the box 1 via a hinge. When the hydraulic cylinder 10 extends, it drives the baffle 7 to move towards the discharge port at the bottom of the box 1, so that the baffle 7 blocks the discharge port of the box 1, allowing the sludge to be concentrated inside the box 1. After the sludge is concentrated, the hydraulic cylinder 10 is retracted, so that the hydraulic cylinder 10 drives the baffle 7 to rotate at the bottom of the box 1 via the rotating seat 9, opening the discharge port of the box 1, allowing the sludge to be discharged from the discharge port of the box 1 by its own gravity.

[0064] In this invention, sludge is conveyed to the center of the housing 1 through the feed pipe 6, and the motor 4 is started to drive the adjusting rod 5 to rotate. The adjusting rod 5, in conjunction with the sleeve 14, moves the two grid plates 13 to the center of the housing 1. At the same time, the grid plates 13 drive the perforated plate 12 and the filter cloth 11 to move synchronously. The two grid plates 13, along with the perforated plate 12 and the filter cloth 11, compress the sludge. Through the filtration effect of the filter cloth 11 and the perforated plate 12, the sludge is gradually concentrated into semi-solid or solid sludge blocks in the housing 1. The water in the sludge is discharged to the inner ends of the housing 1 through the pores of the filter cloth 11 and the perforated plate 12, and the filtered water is discharged to the outer side of the housing 1 through the drain pipe 8. The hydraulic cylinder 10 is retracted, causing the hydraulic cylinder 10 to drive the baffle 7 to rotate at the bottom of the housing 1 through the rotating seat 9, opening the discharge port of the housing 1. The sludge is then discharged from the discharge port of the housing 1 by its own gravity, achieving efficient sludge concentration, reducing equipment wear, and improving processing efficiency.

[0065] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited thereto. Various changes can be made within the scope of knowledge possessed by those skilled in the art without departing from the spirit of the present invention.
