Sludge dewatering machine with stepped shaft

Abstract

The invention relates to a sludge dewatering machine, particularly a sludge dewatering machine with a stepped shaft, which comprises a machine body (1), a bracket (2) and a liquid collection reflux unit (3). The sludge dewatering machine is characterized in that the machine body (1) is arranged above the bracket (2) in parallel, and the liquid collection reflux unit (3) is arranged below the bracket (2); the machine body (1) comprises a cam driving gear (5), a connecting shaft (14), a screw propeller (6), fixed rings (7), floating rings (8) and support vertical plates (9); both ends of the machine body (1) are respectively provided with a sludge outlet (10) and a sludge inlet (11); and the machine body (1) is uniformly provided with the plurality of support vertical plates (9). Compared with the prior art, the sludge dewatering machine has the advantage of no wear, reduces the water content, is simple to operate and easy to replace, and lowers the cost.

Description

technical field [0001] The invention relates to a sludge dewatering machine, more precisely a sludge dewatering machine with a stepped shaft. Background technique [0002] At present, the screw stack sludge dewatering machine of the existing technology on the market can be widely used in the dehydration of oily sludge with different concentrations, high and low viscosities, and oily sludge in all walks of life. It is composed of a fixed ring and a moving ring outside the screw shaft. Through the continuous rotation of the screw shaft, it can squeeze the sludge. Although the sludge dehydrator with this structure has many advantages, it has very obvious defects. , the spiral blades and rings that are constantly rotating during the working process are extremely easy to wear, and the normal continuous service life is less than 3600 hours. After the wear reaches a certain level, the equipment cannot achieve the expected treatment effect, and the later replacement cost is extr...
