Description

Technical Field

[0001] The utility model relates to the technical field of sludge dewatering machines, and more specifically to a deep dewatering type spiral stacking sludge dewatering machine. Background Art

[0002] Sludge is the inevitable product of sewage treatment plants and sewage stations. Sludge that has not been properly treated will directly cause secondary pollution to water bodies and the atmosphere after entering the environment. Since the sludge is still in a liquid flow state after concentration or digestion, the volume is still large and cannot be transported and processed. In order to further reduce the moisture content, the sludge must be dehydrated; the laminated spiral sludge dewatering machine is a water treatment equipment widely used in municipal sewage treatment projects and petrochemical, light industry, chemical fiber, papermaking, pharmaceutical, leather and other industrial industries. After the sludge is concentrated by gravity in the concentration section, it is transported to the dehydration section. In the process of moving forward, as the filter gap and pitch gradually become smaller, and under the blocking effect of the back pressure plate, a huge internal pressure is generated, and the volume continues to shrink, achieving the purpose of full dehydration.

[0003] Existing deficiencies: At the beginning of the operation of the sludge dewatering machine, the incoming sludge to be treated has a high liquid content, and the sludge will enter the dewatering stage before it is fully concentrated in the concentration stage, and will quickly flow out from the outlet, so that the sludge obtained at the beginning is not fully dehydrated; secondly, the back pressure plate of the existing sludge dewatering machine is fixed in position, the sludge with a higher water content has good fluidity, and the extrusion space of the back pressure plate is fixed, which cannot increase the internal pressure of this part of the sludge with good fluidity, which is not conducive to the dehydration of the sludge.
