Description

Technical Field

[0002] In the prior art, for example, a utility model with publication number 202121349034.3 discloses a spiral sludge dewatering machine. In order to solve the problem that the inconvenience in controlling the amount of addition to the dewatering machine affects the dehydration quality, a measuring cylinder, a feed pipe and a valve are provided. A measuring cylinder is used to facilitate personnel to add dehydrating agent in a quantitative manner. When the required dosage is reached, the valve is used to control the opening and closing of the feed pipe for feeding, thereby greatly improving the dehydration quality.

[0003] Similar to the above application, there are still some shortcomings:

[0004] Manual work is still required in the process of adding the dehydrating agent, and the automatic quantitative addition of the dehydrating machine cannot be performed. In addition, during the discharge of the mud, the mud has a certain viscosity and is easy to adhere to the top of the guide plate, affecting the discharge of the mud. In addition, during the cleaning of the processing bin, water is only sprayed from the top through a water pipe, and the sludge falls slowly, affecting the hinge rate;

[0005] Therefore, a spiral-regulated sludge dewatering machine is designed to optimize the above problems. Utility Model Content

A material guiding mechanism consisting of a vertical plate, a guide plate, a top rod and a second spring is provided at the bottom of the sludge discharge port, so that when the sludge falls onto the guide plate, the swing of the guide plate can be controlled, effectively preventing the sludge from sticking to the guide plate and preventing blockage during sludge discharge.
