Abstract
A spiral batch-type sludge extruding dewaterer comprises a mandrel 7 which is driven by a motor 2 through a transmission device, and two ends of the mandrel are respectively installed on corresponding support seats. Helical blades 8 which are equal in screw pitches and located in a filter drum 9 are arranged on the mandrel 7, one end of the filter drum 9 is communicated with a sludge outlet 14 through a clamp ring 6 capable of adjusting opening of the end port, and the other end of the filter drum 9 is provided with a sludge inlet 10. A sludge extruding cavity between the mandrel 7 and the filter drum 9 is divided into at least two variable volume cavities and an equal volume cavity by the helical blades 8, and the variable volume cavities and the equal volume cavity are arranged along the axial direction of the mandrel 7 at intervals. The volume of each variable volume cavity is decreased stage by stage from the direction of the sludge inlet 10 to the direction of the sludge outlet 14, and the length of a section of screw pitch is a stage. Moisture content of sludge which is dewatered by adopting the dewaterer is low, and the spiral batch-type sludge extruding dewaterer is easy to maintain, small in occupied area and low in running cost and can continuously work for 24 hours.
Description
Technical field
The utility model relates to the dewatering processing device of mud that sewage disposal produces.
Background technology
After sewage work's sewage disposal, can produce a large amount of mud.The water ratio of mud is between 95%～98%.Sewage work all adopts the mechanical dehydration mode to sludge dewatering at present, and dewatering machine has vacuum belt machine, centrifuge, plate-and-frame filter press, belt filter press etc.Adopt these mechanical dehydrations, the water ratio of mud is reduced between 78%～82%, and occupation area of equipment is big, operating environment is poor, and the maintenance amount is big, the running cost height.
The utility model content
The technical problems to be solved in the utility model is, defective at the prior art existence, a kind of spiral intermittent type mud extruding-desiccation machine is provided, adopt the moisture percentage in sewage sludge low (60%) after this equipment dewaters, the easy care maintenance, floor space is little, and running cost is relatively low, can work in continuous 24 hours.
The technical solution of the utility model is, described spiral intermittent type mud extruding-desiccation machine comprises that two ends are installed on the corresponding supporting base respectively and by the mandrel of electric motor by actuator drives, this mandrel is provided with the uniform pitch screw-blade that is arranged in filter cylinder, the clamp ring of filter cylinder one end through regulating this end port aperture is communicated with mud mouth, and the other end of described filter cylinder is provided with mud inlet; It is characterized in that the mud extrusion chamber between mandrel and the filter cylinder is divided at least two by described screw-blade and becomes cavity volumes and isometric(al) chamber, and become cavity volume and isometric(al) chamber axially alternately along mandrel; The volume edge that becomes cavity volume is reduced step by step by the direction of mud inlet towards mud mouth, and a joint pitch length is an one-level.
Below the utility model made further specify.
Referring to Fig. 1, working process of the present utility model and know-why are, mandrel 7 rotates under electric motor 2 drives, and the screw-blade 8 on the mandrel 7 promotes to advance to mud mouth 14 extruding from the mud that mud inlet 10 is come in, and the water of extruding in the process of advancing flows out from the aperture on the filter cylinder 9; Regulate the spacing between clamp ring 6 and filter cylinder 9 ports, can regulate squeeze pressure in the filter cylinder, with the mass dryness fraction of mud.The volume that becomes cavity volume successively decreases along the mud direct of travel, and mud is compressed in cavity, and moisture is separated in mud; The isometric(al) chamber can make the intermolecular gap of mud keep no longer being compressed, and keeps the unimpeded outflow of moisture; Second section volume that becomes cavity volume successively decreases once more, mud is compressed therein again, and second isometric(al) chamber makes the intermolecular gap of mud keep once more not being compressed; By that analogy, make mud reach required water ratio.
As known from the above, the utility model is a kind of spiral intermittent type mud extruding-desiccation machine, adopts the moisture percentage in sewage sludge after this equipment dewaters can be low to moderate 60%, the easy care maintenance, and floor space is little, and running cost is relatively low, can work in continuous 24 hours.
