Wear-free screw-lapping sludge dewatering machine

Abstract

The invention refers to a sludge dewatering machine. More definitely, the invention relates to a wear-free screw-lapping sludge dewatering machine which comprises a machine body (1), a bracket (2), and a liquid collecting backflow device (3). The wear-free screw-lapping sludge dewatering machine is characterized in that the machine body (1) is arranged at the upper part of the bracket (2) in parallel, the liquid collecting backflow device (3) is arranged at the lower part of the bracket (2); the machine body (1) comprises a cam driving device (5), a connecting shaft (14), a spiral pusher (6), a fixing ring (7), a movable ring (8), and vertical supporting plates (9); and a mud outlet (10) and a mud inlet (11) are respectively arranged at both ends of the machine body (1); a plurality of vertical supporting plates (9) are uniformly arranged on the machine body (1). Compared with the prior art, the wear-free screw-lapping sludge dewatering machine has the outstanding advantages as follows: 1, wear-free; 2, moisture content is reduced; 3, operation is simple and replacement can be easily achieved; and 4, cost is reduced.

Description

Technical field [0001] The invention relates to a sludge dewatering machine, more specifically, a wear-free stacked screw sludge dewatering machine. Background technique [0002] At present, the existing technology of the snail sludge dewatering machine on the market can be widely used in the dewatering of different concentrations and high and low viscosities and oily sludge in various industries. The snail sludge dewatering machine is through the screw shaft and sleeve The fixed ring and the floating ring outside the screw shaft are composed of the continuous rotation of the screw shaft to squeeze the sludge. Although the sludge dehydrator of this structure has many advantages, it has very obvious defects. The spiral blades and rings that rotate continuously during the working process are extremely easy to wear, and the normal continuous service life is less than 3600 hours. After a certain degree of wear, the equipment cannot achieve the expected treatment effect, and the later...

AI Technical Summary

Problems solved by technology

[0002] At present, the snail 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. The fixed ring and the swimming ring outside the screw shaft are composed of a rotating ring, which can squeeze the sludge through the continuous rotation of the screw shaft. Although the sludge dewatering machine 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 very easy to wear and tear, and the normal continuous service life is less than 3600 hours. After wearing to a certain extent, the equipment cannot achieve the expected treatment effect, and the later replacement cost is extremely high, and disassembly is very inconvenient
