Description

Technical Field

[0001] The invention relates to the technical field of sludge treatment, in particular to sludge treatment equipment. Background Art

[0002] Sludge treatment equipment is a kind of equipment for treating and drying sludge. During the working process, the water in the sludge is filtered out by the filtering device, and then the sludge is further treated by the extrusion equipment to form relatively dry mud. Commonly used sludge treatment equipment includes belt filter press, vacuum filter press, spiral separator, etc.

[0003] For example, the prior art CN113248107B proposes a high-efficiency sludge treatment device, which includes a dehydration mechanism connected to a drying mechanism. The device uses the heat in the high-temperature flue gas to achieve drying treatment of the sludge. Although this method can achieve sludge drying, the method of using heat to evaporate water has a slow drying speed, a slow sludge treatment speed, and cannot recover water. In addition, the device is subject to large constraints and can only be used in occasions that can generate high-temperature waste flue gas. Otherwise, a large amount of energy is required to obtain heat, which consumes a huge amount of energy and is difficult to promote.

[0004] In view of the defects of the above-mentioned technologies, the prior art CN118439775B proposes a sludge treatment device, which includes an equipment frame, a mixing mechanism, a diversion mechanism and a mud-water separation mechanism. The device uses two sets of filter belts to squeeze the sludge to filter the water of the sludge, and can recycle the water.

[0005] However, the equipment is unable to screen out large objects in the sludge when it is working. The large objects mixed in the sludge will cause serious damage to the filter belt during the subsequent filter belt squeezing, resulting in holes and mud leakage in the filter belt. At the same time, when processing the sludge, the incoming sludge amount is often unbalanced, which will cause the amount of sludge entering the filter belt to be very unbalanced, sometimes more and sometimes less. If there is too much incoming material, the sludge will be squeezed out from both sides of the filter belt during squeezing, causing mud overflow. Summary of the invention
