[0003] In the prior art, general large and medium-sized sewage treatment plants adopt mechanical dehydration. There are many types of dehydration machines. According to the principle of dehydration, they can be divided into three categories: vacuum filtration dehydration, filter press dehydration, and centrifugal dehydration. Commonly used models include centrifugal, Filter belt type, spiral ring butterfly type, and plate-and-frame type; centrifugal dehydrator has high noise, high energy consumption, continuous work, and less infrastructure; plate-and-frame type centrifuge occupies a large area, cannot work continuously, and has a high dehydration rate; belt type dehydration The machine works continuously, the equipment is easy to manufacture, and the dehydration rate is average

The invention discloses a vertical sludge dewatering machine in the field of sludge treatment. The dewatering machine includes a fixed frame, a centrifugal dewatering mechanism for dehydrating sludge by centrifugal method, and a The blanking mechanism that stirs the sludge to ensure the uniform output of the sludge also includes a rolling dehydration mechanism for secondary extrusion and dehydration of the sludge, and also includes a sludge dewatering mechanism connected with the centrifugal dehydration mechanism for transporting sludge. The mud pipe also includes a flushing pipe connected with the sludge pipe and used for delivering cleaning water. The invention connects two dewatering mechanisms with different working principles in series to dehydrate the sludge twice, thereby improving the dewatering effect on the sludge.
Description
technical field [0001] The invention relates to the technical field of sludge treatment, in particular to a vertical sludge dehydrator. Background technique [0002] Sewage treatment is a subject of widespread concern in the society. A large amount of sludge will be generated in the process of sewage treatment. Whether the sludge can be properly treated is related to the success or failure of sewage treatment, and the dehydration treatment of sludge is the key technology of sludge treatment. one. [0003] In the prior art, general large and medium-sized sewage treatment plants adopt mechanical dehydration. There are many types of dehydration machines. According to the principle of dehydration, they can be divided into three categories: vacuum filtration dehydration, filter press dehydration, and centrifugal dehydration. Commonly used models include centrifugal, Filter belt type, spiral ring butterfly type, and plate-and-frame type; centrifugal dehydrator has high noise, hig...
