Silt extraction machine

Abstract

The invention discloses a silt extraction machine. The silt extraction machine comprises a whole fixing platform, wherein the whole fixing platform is arranged on a floating body and is convenient to operate. The silt extraction machine is characterized in that: the whole fixing platform is provided with a power machine; the whole fixing platform is provided with a bracket acting on a silt collection box; the bracket is provided with a gourd pendant which is connected to the silt collection box through a chain; the silt collection box is provided with a screw device; the whole screw device is in a horn shape with a smaller upper side and a larger lower side, and a screw shaft is arranged in the screw device; the power machine directly acts on the screw shaft of the screw device through a power transmission shaft; a screw blade is also arranged in the screw device; the screw blade surrounds the screw shaft and is in a screw shape; and the upper part of the screw device is provided with a silt outlet which is externally connected with a slurry output pipe. By arranging the screw device on the silt collection box, the screw blade on the screw device can fast soften firm silt under the action of the power machine, and the silt with extremely high consistence can be delivered outside by screw extrusion. The silt extraction machine solves the problems that the slit with high consistence and high impurity content is difficultly extracted by the conventional silt machine and is difficult to stack and use.

Description

Technical field: [0001] The invention relates to a device for treating sludge, in particular to a sludge extractor. Background technique: [0002] At present, a large amount of silt will be accumulated in ponds or other places due to various reasons, and the problem of a large amount of silt accumulation has become increasingly prominent. It has been reported that excessive silt accumulation will inevitably lead to a decline in the effective water level and affect the water ecological environment. . Due to the deposition of residual bait and fish excrement, etc., the pond bottom mud increases year by year with a thickness of 6-8cm. 91.9% of the bottom mud thickness is greater than 40cm, and 47.4% of them have a thickness of 60-80cm; Deposition at the bottom of the pool will have a significant impact on both the pool water and the bottom quality. The pH value of the pool water will drop, and the content of ammonia nitrogen, nitrite, and sulfide will increase. Ther...
