Background technology
Along with the quickening of socioeconomic development and urbanization process, urban wastewater treatment firm and the amount of sludge supervened 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 moisture content of mud can only be reduced to about 80% by the existing equipment of nearly all sewage treatment plant and technology, moisture content as the requirement mud that will reach burning will spend very high cost lower than 50%, therefore serious problem of environmental pollution often by mud based on landfill and stacking, thus can only cause in nearly all sewage treatment plant of China.
In prior art, sludge treatment equipment generally includes sludge concentration device and the dewaterer of independent setting, when carrying out Treatment of Sludge, first utilizes sludge concentration device to concentrate rarer mud, and the mud that after concentrated, water content reduces enters dewaterer dehydration again.This Treatment of Sludge mode, one is that equipment investment is large, and equipment occupation space is large, and energy consumption is high, and operating cost is high; Two are, existing sludge concentration device easily blocks, 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 with tradition, treatment effect obviously reduces compared with the device of split of dewatering.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned weak point, thus press filtration strainer mechanism under a kind of mud is provided, can fully squeeze the moisture extruded in mud, improve dewatering efficiency and the dehydration quality of mud, reduce operating cost.
According to the technical scheme that the utility model provides, 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 follower rollers, are set with lower filter belt between head roll and follower rollers, housing is positioned at head roll one end and is provided with mud discharging opening; 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 walks 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 place of lower filter belt is 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 walks around two directive wheels, and two directive wheels lay respectively at two ends, left and right in housing.
Compared with the prior art the utility model has the following advantages:
The utility model structure is simple, compact, reasonable, and working stability is reliable; Can fully squeeze the moisture extruded in mud, improve dewatering efficiency and the dehydration quality of mud, reduce operating cost.

Detailed description of the invention
Embodiment in is by reference to the accompanying drawings further described by the utility model below:
As shown in Figure 1, the utility model mainly comprises housing 1, and in housing 1, two ends, left and right are respectively equipped with head roll 2 and follower rollers 3, are set with lower filter belt 4 between head roll 2 and follower rollers 3.Housing 1 is positioned at head roll 2 one end and is provided with mud discharging opening 15.
Lower filter belt 4 lower end is provided with deviation correction mechanism, and deviation correction mechanism compresses lower filter belt 4, can prevent lower filter belt 4 sideslip.
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 end is provided with strainer, and strainer compresses lower filter belt 4, can regulate the tensioning degree of lower filter belt 4.
Described strainer comprises tensioning cylinder 5 and tensioning support 6, and the cylinder rod front end of tensioning cylinder 5 connects tensioning support 6, and tensioning support 6 compresses lower filter belt 4, thus regulates the tensioning degree of lower filter belt 4.
The second half section place of lower filter belt 4 is provided with catch tray 7, and catch tray 7 can collect the moisture flowed out in lower filter belt 4.
