Embodiment Construction

[0028] like Figure 1-12 As shown, a sludge dewatering and feeding equipment that is convenient for extrusion includes a working box 1, and the working box 1 is provided with a feeding chamber 2 for transporting sludge and a dehydration chamber 3 for dehydrating the sludge. The dewatering chamber 3 is provided with a discharge port 31, and the feeding chamber 2 is provided with a screw feed rod 21 for transporting sludge to the dewatering chamber 3 and a screw rod for scraping the sludge on the blades of the screw feed rod 21. Sludge scraping device, the dewatering chamber 3 is provided with a first conveyor belt 32 and a second conveyor belt 33 for extruding sludge. Through the setting of the above structure, the sludge can be stirred to a certain extent in the feeding chamber, so that the sludge Discharge evenly into the dewatering chamber, so as to ensure the uniform distribution of sludge, avoid the sludge being transported in lumps, which will cause the machine to be stuc...

Abstract

The invention discloses a sludge dewatering and feeding device convenient for extrusion. The sludge dewatering and feeding device comprises a working box, wherein the working box is provided with a feeding cavity for conveying sludge and a dewatering cavity for dewatering the sludge; the dewatering cavity is internally provided with a first conveying belt and a second conveying belt for extrudingsludge; the feeding cavity is provided with a heating chamber for heating the sewage; and the heating chamber is communicated with the dewatering cavity by virtue of a water supply pipeline. By adopting the structure, a pre-heating effect can be realized by heating the sewage before the sludge is dried, so that the time required for drying the sludge is effectively shortened, and the drying efficiency of the sludge is improved.

Description

technical field [0001] The invention belongs to the technical field of environmental protection equipment, and in particular relates to a sludge dewatering and feeding equipment which is convenient for extrusion. Background technique [0002] After the sewage treatment plant treats the sewage, sludge will inevitably remain, and the sludge cleared from the sedimentation tank is mushy due to its high water content. Pasty sludge is bulky, difficult to store, inconvenient to transport, and not conducive to subsequent resource utilization. In order to further reduce the water content of sludge in the project, dehydration equipment is usually used for sludge dehydration treatment. [0003] A kind of belt type sludge dewatering machine is disclosed in the open document that now publication number is CN101306911B, and the water yield that this device consumes when cleaning the filter cloth of belt type sludge dewatering machine is greatly reduced, and belt type sludge dewatering ma...
