Abstract
The utility model relates to a belt type dewaterer. The utility model is provided with a material baffle and a water baffle on a filtering belt at the gravity dewatering zone, and dewatering effect in the gravity dewatering zone can be improved. The utility model has simple structure, and the utility model is particularly suitable for sludge dewatering operation or solid-liquid separation in sewage treatment.
Description
Affiliated technical field
The utility model is a kind of water extracter, is specially adapted to sludge dewatering or solid-liquid separation in the sewage treatment process.
Background technology
Mud in the sewage treatment process need carry out processed.Existing sludge dehydration device exists defectives such as unreasonable structure, dewatering efficiency be low mostly to some extent, the water separation capability that mainly shows the gravity dehydration district a little less than, cause the sludge treatment effect not ideal enough.For addressing this problem, the belt filter press that the manufacturer that has produces sets up a preposition sludge concentration device, though dehydrating effect is better, has brought new defectives such as device structure complexity, cost height, inconvenient maintenance.
Summary of the invention
The purpose of this utility model is a kind of simple in structure, belt water extracter that result of use is good of design.
The utility model comprises the strainer that is connected on supporting roll and the bridle rolls, and this strainer forms gravity dehydration district and extrusion dehydration district respectively, it is characterized in that being provided with blocking material plate on the strainer in gravity dehydration district.
The utility model also is provided with water eliminator in the both sides of the upper surface of gravity dehydration district strainer.Said extrusion dehydration district comprises wedge shape extrusion dehydration district and tensioning extrusion dehydration district.Said strainer comprises lower filter belt and last strainer.Described bridle rolls comprises bridle rolls and following bridle rolls.
The utility model is provided with a blocking material plate on the strainer that is in the gravity dehydration district, in the working process, when the muddy water throw out moves forward with strainer, under the obstruction effect of blocking material plate, make the muddy water throw out layer thickening on the strainer, increased its action of gravity, the free-water in the muddy water throw out is more easily filtered lower filter screen under the effect of gravity, thereby has improved the dehydrating effect in gravity dehydration district.Simultaneously, because the effect of blocking material plate, make the muddy water throw out before blocking material plate, form slope with certain slope, the water of good fluidity flows towards the direction opposite with strainer direction of motion downwards with the slope, before the mud of mobile difference is deposited in blocking material plate, when reaching a certain height, just can surmounting blocking material plate, to enter next drying zone with strainer be the wedge shape drying zone, finished the concentration process of muddy water throw out preferably.The muddy water throw out water ratio that surmounts blocking material plate reduces greatly than original system, for follow-up dehydration procedure has been created very strong dehydration conditions.The utility model is simple in structure, reasonable in design, result of use is good, can be widely used in municipal administration, chemical industry, metallurgy, machinery, food, brewages, the sludge dewatering in the industry sewage treatment process such as papermaking, medicine, coal, gold and the solid-liquid separation in other technological process.
Description of drawings
Accompanying drawing is the structural representation of the utility model embodiment.
Embodiment
The accompanying drawing illustrated embodiment has the strainer that is connected on supporting roll and the bridle rolls, and this strainer comprises lower filter belt 1 and last strainer 2.Described strainer forms I district, gravity dehydration district, II district, wedge shape extrusion dehydration district and III district, tensioning extrusion dehydration district respectively.Be provided with blocking material plate 5 on the strainer in I district, gravity dehydration district, the both sides of the strainer upper surface between blocking material plate 5 and the feed end 3 also are provided with the water eliminator of being made by rubber 7.Described bridle rolls comprises bridle rolls 4 and following bridle rolls 6.In the working process, after the mud that flocculation reactor is handled becomes throw out, at first enter I district, gravity dehydration district through feed end 3 and carry out gravity dehydration, enter the II district, wedge shape extrusion dehydration district that forms by two strainers then and continue dehydration, enter III district, tensioning extrusion dehydration district at last and further finish dehydration after the dehydration.Present embodiment is compared with existing gravity thickening machine, and during mud in handling paper technology sewage, processing power can improve 40%, and moisture content of the cake descends 3.8%; When the mud in the chemical fibre process spent water was handled, processing power can improve 45%, and moisture content of the cake descends 4.2%, and result of use is better.
