[0002] Sewage treatment, papermaking, printing and dyeing, leather, chemical, pharmaceutical and food companies generate a large amount of sludge, which is initially dehydrated and then landfilled. Since landfilling does not meet environmental protection requirements, incineration is used. This requires that the sludge should reach a certain solid content to reduce the energy consumed by incineration. Currently, there are mainly belt filter presses and plate and frame filter presses.

[0003] According to the Chinese patent application number 202020009154.8, a high-pressure belt sludge dewatering machine is proposed. The device can perform conveying high-pressure dewatering on the sludge, so that the dewatering efficiency of the whole process is relatively high, and the upper filter cloth belt is laid on the outer wall of the upper driving crawler and the lower filter cloth belt is laid on the outer wall of the lower driving crawler, so that the overall dewatering stability is high, and the overall dewatering process is simple, convenient and efficient.

[0004] However, after the improvement, the above patent cannot flatten the undehydrated sludge, which will cause the sludge to pile up and enter the dehydration mechanism, affecting the dehydration effect of the device. For this reason, we propose a crawler sludge dehydrator. Utility Model Content
