Technical field
The present invention relates to a kind of sludge treatment equipment, press filtration strainer mechanism under a kind of mud, belongs to environmental protection equipment technical field specifically.
Background technology
Along with the quickening of socioeconomic development and urbanization process, urban wastewater treatment firm and the amount of sludge of supervening increase fast. According to related materials, the mud of wastewater treatment in China factory generation in 2010 reaches 300,000,000 tons. Because mud must carry out biochemistry, flocculation treatment in dehydration, and dehydrated sludge contains a large amount of cellular water and attached water, at present, the existing equipment of nearly all sewage treatment plant and technology can only be reduced to 80% left and right by the moisture content of mud, as the moisture content that requires mud that will reach burning will spend very high cost lower than 50%, therefore nearly all sewage treatment plant of China often can only be by mud taking landfill and stacking as main, thereby has caused serious problem of environmental pollution.
In prior art, sludge treatment equipment generally includes independent sludge concentration device and the dewaterer arranging, and while carrying out Treatment of Sludge, first utilizes sludge concentration device to concentrate rarer mud, and the mud of concentrated rear reduced water content enters dewaterer dehydration again. This Treatment of Sludge mode, the one, equipment investment is large, and equipment occupation space is large, and energy consumption is high, and operating cost is high; The 2nd,, existing sludge concentration device easily stops up, thus inefficiency, operating cost is high, and limited for the concentrated effect of mud. In recent years, also someone reports thickening all-in-one, but the treatment effect of existing thickening all-in-one concentrates, dewaters with tradition, compared with the device of split, treatment effect obviously reduces.
Summary of the invention
The object of the invention is to overcome above-mentioned weak point, thereby press filtration strainer mechanism under a kind of mud is provided, can fully squeeze the moisture of extruding in mud, improve dewatering efficiency and the dehydration quality of mud, reduced operating cost.
According to technical scheme provided by the invention, under mud, press filtration strainer mechanism comprises housing, it is characterized in that: in housing, two ends, left and right are respectively equipped with head roll and driven cylinder, between head roll and driven cylinder, are set with lower filter belt, be positioned at head roll one end and be provided with mud discharging opening on housing; Lower filter belt lower end is provided with deviation correction mechanism, and deviation correction mechanism compresses lower filter belt, and lower filter belt upper end is provided with strainer, and strainer compresses lower filter belt; Lower filter belt lower semisection is walked around the first pinch roller, the second pinch roller and the 3rd pinch roller successively, and lower filter belt lower semisection is provided with Flushing nozzle.
Further, deviation correction mechanism comprises correction wheel and rectifying cylinder, and the cylinder rod front end of rectifying cylinder connects correction wheel, and correction wheel compresses lower filter belt.
Further, strainer comprises tensioning cylinder and tensioning support, and the cylinder rod front end of tensioning cylinder connects tensioning support, and tensioning support compresses lower filter belt.
Further, the second half section of lower filter belt locates to be provided with catch tray.
Further, the diameter of the first pinch roller is greater than the diameter of the second pinch roller, and the diameter of the second pinch roller is greater than the diameter of the 3rd pinch roller.
Further, lower filter belt lower semisection is walked around two directive wheels, and two directive wheels lay respectively at two ends, left and right in housing.
Compared with the prior art the present invention has the following advantages:
The present invention is simple in structure, compact, reasonable, and working stability is reliable; Can fully squeeze the moisture of extruding in mud, improve dewatering efficiency and the dehydration quality of mud, reduce operating cost.

Detailed description of the invention
The present invention is below further described in connection with the embodiment in accompanying drawing:
As shown in Figure 1, the present invention mainly comprises housing 1, and two ends, the interior left and right of housing 1 are respectively equipped with head roll 2 and driven cylinder 3, between head roll 2 and driven cylinder 3, are set with lower filter belt 4. On housing 1, be positioned at head roll 2 one end and be provided with mud discharging opening 15.
Lower filter belt 4 lower ends are provided with deviation correction mechanism, and deviation correction mechanism compresses lower filter belt 4, can prevent lower filter belt 4 sideslips.
Described deviation correction mechanism comprises correction wheel 12 and rectifying cylinder 13, and the cylinder rod front end of rectifying cylinder 13 connects correction wheel 12, and correction wheel 12 compresses lower filter belt 4.
Lower filter belt 4 upper ends are provided with strainer, and strainer compresses lower filter belt 4, can regulate the tensioning degree of lower filter belt 4.
