Description

Technical Field

[0001] The utility model relates to the technical field of solid-liquid separation, and more specifically to a sludge high-efficiency solid-liquid separation device. Background Art

[0002] Silt is a soft soil with a natural water content greater than the fluidity limit and a porosity greater than 1.5. It is a modern sediment formed in an environment with slow water flow and the participation of microorganisms. When silt is formed in the riverbed, it needs to be cleaned regularly to ensure the normal operation of the river. At the same time, when the silt is treated, the silt needs to be separated from the solid and liquid.

[0003] After searching, the utility model patent with announcement number CN220502882U discloses a river sludge solid-liquid separation device, including: a sub-screen mounting seat is fixedly installed inside the separation box, and a separation box upper cover is arranged on the top of the separation box; a feed pipe is arranged at the bottom of the separation box upper cover, a fixed paddle is fixedly installed on the surface of the feed pipe, and a spiral guide plate is fixedly arranged inside the feed pipe; the sub-screen is arranged inside the separation box, and a vibration plate is fixedly arranged on the surface of the sub-screen; this patent arranges a vibration plate on the surface of the sub-screen, and the gravity of the sludge drives the feed pipe to rotate through the spiral guide plate. During the rotation of the feed pipe, the vibration plate is paddled by the fixed paddle, so that the vibration plate can vibrate after being paddled, and the vibration of the vibration plate will drive the sub-screen to vibrate. The vibration of the sub-screen accelerates the water in the sludge on the surface of the sub-screen to pass through the solid impurities and the sub-screen, thereby improving the efficiency of solid-liquid separation.

[0004] However, the above patents still have the following shortcomings: the effect of solid-liquid separation by relying solely on the deadweight and vibration of the sludge is poor, and the sludge on the sieve is not easy to discharge by relying on the deadweight and vibration. Therefore, we propose a sludge high-efficiency solid-liquid separation device. Utility Model Content

[0026] In this embodiment, the squeezing roller 7 is used to squeeze the sludge on the filter steel belt 4, so as to ensure complete solid-liquid separation of the sludge.

[0027] For details, please refer to Figure 1 , Figure 3 and Figure 4 The pushing mechanism 10 includes a rotating rod 11 rotatably connected to the inner cavity of the separation box 1, the rotating rod 11 passes through the inner side of the filter steel belt 4, and a plurality of pushing columns 12 are fixedly connected to the outer side of the rotating rod 11.

A synchronous belt 15 is transmission-connected between the first synchronous wheel 13 and the second synchronous wheel 14.

[0028] In this embodiment, the filter steel belt 4 is pushed by the rotation of the push column 12, so that the filter steel belt 4 vibrates, so as to separate the sludge into solid and liquid.

[0029] For details, please refer to Figure 3 The inner cavity of the separation box 1 is rotatably connected with a plurality of support rollers 16 , and the support rollers 16 penetrate the inner cavity of the filter steel belt 4 , and the top surface of the support rollers 16 fits with the inner side surface of the filter steel belt 4 .
