Description
Technical field
The utility model relates to a kind of sludge treatment equipment, and press filtration strainer mechanism on a kind of mud, belongs to technical field of environment protection equipment specifically.
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 water ratio of mud can only be reduced to about 80% by the existing equipment of nearly all sewage work and technology, water ratio 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 work of China.
In prior art, sludge treatment equipment generally includes sludge concentration device and the water extracter of independent setting, when carrying out sludge treatment, first utilizes sludge concentration device to concentrate rarer mud, and the mud that after concentrated, water-content reduces enters water extracter dehydration again.This sludge treatment mode, one is that facility investment is large, and equipment occupation space is large, and energy consumption is high, and running cost is high; Two are, existing sludge concentration device easily blocks, thus inefficiency, running 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 provides press filtration strainer mechanism on a kind of mud, can fully squeeze the moisture extruded in mud, improves dewatering efficiency and the dehydration quality of mud, reduces running cost.
According to the technical scheme that the utility model provides, on mud, press filtration strainer mechanism comprises housing, it is characterized in that: in housing, two ends are respectively equipped with head roll and follower rollers, between head roll and follower rollers, strainer loaded onto by cover, housing is positioned at head roll one end and is provided with discharge port; Upper strainer upper end is provided with deviation correction mechanism, and deviation correction mechanism compresses upper strainer; Upper strainer lower end is provided with strainer, and strainer compresses upper strainer; Upper strainer lower semisection walks around one first squeezing wheel, a second squeezing wheel and several the 3rd squeezing wheels successively; Described upper strainer upper end is provided with Flushing nozzle.
Further, deviation correction mechanism comprises rectifying cylinder and correction wheel, and the cylinder rod front end of rectifying cylinder connects correction wheel, and correction wheel compresses upper strainer.
Further, strainer comprises tensioning cylinder and tensioning support, and the cylinder rod front end of tensioning cylinder connects tensioning support, and tensioning support compresses upper strainer.
Further, the diameter of the first squeezing wheel is greater than the diameter of the second squeezing wheel, and the second squeezing wheel is greater than the diameter of the 3rd squeezing wheel.
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 running cost.
Accompanying drawing explanation
Fig. 1 is the utility model front view.
Description of reference numerals: 1-housing, 2-head roll, 3-follower rollers, the upper strainer of 4-, 5-rectifying cylinder, 6-correction wheel, 7-tensioning cylinder, 8-tensioning support, 9-first squeezing wheel, 10-second squeeze wheel, 11-the 3rd squeezing wheel, 12-Flushing nozzle, 13-discharge port.
Embodiment
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 are respectively equipped with head roll 2 and follower rollers 3, and between head roll 2 and follower rollers 3, strainer 4 loaded onto by cover.Housing 1 is positioned at head roll 2 one end and is provided with discharge port 13.
Upper strainer 4 upper end is provided with deviation correction mechanism, and deviation correction mechanism compresses upper strainer 4, can prevent strainer 4 sideslip.
Described deviation correction mechanism comprises rectifying cylinder 5 and correction wheel 6, and the cylinder rod front end of rectifying cylinder 5 connects correction wheel 6, and correction wheel 6 compresses upper strainer 4.
Upper strainer 4 lower end is provided with strainer, and strainer compresses upper strainer 4, can regulate the tensioning degree of strainer 4.
Described strainer comprises tensioning cylinder 7 and tensioning support 8, and the cylinder rod front end of tensioning cylinder 7 connects tensioning support 8, and tensioning support 8 compresses upper strainer 4, thus regulates the tensioning degree of upper strainer 4.
Upper strainer 4 lower semisection walks around one first squeezing 9, one second, wheel squeezing wheel 10 and several the 3rd squeezing wheels 11 successively, squeeze the mud on wheel 10 and the upper strainer 4 of the 3rd squeezing wheel 11 extruding by the first squeezing wheel 9, second, the moisture in mud is fully squeezed.
The diameter of described first squeezing wheel 9 is greater than the diameter of the second squeezing wheel 10, and the second squeezing wheel 10 is greater than the diameter of the 3rd squeezing wheel 11.
Described upper strainer 4 upper end is provided with Flushing nozzle 12, and Flushing nozzle 12 can rinse upper strainer 4.
During utility model works, mud relies on the effect of gravity to leach portion of water at sludge thickening dehydrator enriching section, enters the filter pressing section of sludge thickening dehydrator under filter cloth drives slowly; Mud relies on the extruding of cylinder between the filter cloth of tensioning, constantly discharges moisture, on filter cloth, finally form the state of mud cake; Mud cake drops from filter cloth and collects under the effect of dumping device, and filter cloth press filtration mud again after being cleaned up by wash-down water in pivotal process, wash-down water and filtrate flow out along waterways after collector groove collects.
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 running cost.
