Abstract
The invention discloses a sludge filtrating machine which is energy-saving, simple in operation and high in deslugding rate and belongs to the technical field of sludge dewatering. The filtering machine is structurally characterized in that a driving motor is arranged in a shell and connected with a driving shaft; the driving shaft is connected with an electric cabinet; the lower part of the electric cabinet is provided with a discharge port; the end part of the driving shaft is provided with a conical body; and the inlet of the conical body is connected with a filtration shower head. According to the sludge filtering machine, the conical body structure is adopted for dewatering and compacting waste materials, so that the volume is reduced, and thus the filtration cost is reduced; the semicircular filtration shower head is adopted, so that the filtration efficiency is high; an Archimedes screw rod is used for transferring the waste materials intercepted by a filtering net to the conical body, and then most moisture of the waste materials is removed by virtue of pressure generated by the conical body; and a special brush at the outer edge of the screw rod is used for thoroughly cleaning holes of a filter and preventing the holes from being blocked.
Description
Technical field
The invention belongs to sludge dewatering technical field, be specifically related to a kind of energy-conservation, simple to operate, wear-resistant, the mud filter that desliming rate is high.
Background technology
On existing market, mainly contain 4 kinds of sludge dewatering equipments: belt filter press, plate-and-frame filter press, centrifuge and spiral sludge dewatering machine.These 4 kinds of each have their own merits and demerits of sludge dewatering equipment, entirety is compared as follows:
1) centrifuge utilizes centrifugal settling principle, makes solid-liquid separation, owing to there is no filter screen, can not cause obstruction, and belt filter press utilizes strainer to make solid-liquid separation, for preventing that strainer from stopping up, and needs high pressure water constantly to wash away.
2) centrifuge is suitable for the concentrated and dehydration of all kinds of mud, and belt filter press is also suitable for multiple mud, but need throw a large amount of medicaments and dehydration difficulty to residual active sludge and waterworks sludge.
3) centrifuge in dehydration in the time that input concentration changes, the slip of rotary drum and spiral and moment of torsion can be from motion tracking adjustment, so can not establish special messenger's operation, and belt filter press in dehydration in the time that input concentration changes, the rate of tension of belt speed, band, chemical feeding quantity, wash-down water pressure all need to adjust, and operational requirement is higher.
4) in centrifuge, tiny mud also can separate with water, so the dosage of flocculation agent is less, chemical feeding quantity when general mixing sludge dehydration is: the dry mud of 2～4kg/t[], the mud rate of recovery is more than 95%, and after dehydration, the water ratio of mud cake is 65%-75% left and right; And belt filter press is because strainer can not be knitted get Tai Mi, slip through the net for preventing tiny mud, need add more flocculation agent so that mud forms larger floc sedimentation, chemical feeding quantity when general mixing sludge dehydration is greater than the dry mud of 4kg/t[], the mud rate of recovery is 90% left and right, moisture content of the cake 80% left and right after dehydration.
5) every cubic metre of sludge dewatering power consumption of centrifuge is 1.2kW/m3, and when operation, noise is 76-80db, and whole day 24h moves continuously, except shutting down, and the rinse water that do not need in service; And every cubic metre of sludge dewatering power consumption of belt filter press is 0.8kW/m3, when operation, noise is 70～75db, the filter cloth maintenance that need relax, and only arrange two classes of operations general every day, needs constantly to use high pressure water washing filter cloth in operational process;
6) centrifuge takes up room littlely, and installation and debugging are simple, and support equipment only has dosing and input and output material transfer roller, the hermetically sealed operation of complete machine, and workshop condition is good; And belt filter press floor space is large, support equipment, except dosing and input and output material transfer roller, also needs flushing pump, air compressor machine, and sludge conditioner etc., complete machine stopping property is poor, high pressure cleaning water smoke and stink contaminate environment, as manage bad meeting and cause mud to overflow.
7) spiral sludge dewatering machine running cost is low: be equivalent to belt filter press 40% less than, be equivalent to centrifuge 20% less than; Power consumption is less than 5% of whizzer; Water consumption is less than 0.1% of belt filter press; The average medicine 60% of economizing; Dehydration machine room reduced investment is more than 60%; Containing the jinx of lipid fiber-like mud.But the wearing and tearing of this kind of moving fixed ring of sludge dewatering equipment later stage, the expense of the fixed ring that more moves is also a very large expense.
