Abstract
The invention relates to a concave and convex rolling shaft pressure device of a belt filter press. The concave and convex rolling shaft pressure device of the belt filter press comprises a ring-shaped flocking filter belt and a pressure rolling shaft, wherein a driven rolling shaft and a driving rolling shaft are respectively arranged at the two sides of the circular arc surface of the pressure rolling shaft; a plurality of extrusion rolling shafts are arranged under the pressure rolling shaft; the flocking filter belt is sheathed on the driven rolling shaft, the driving rolling shaft and the extrusion rolling shafts, and is extruded by the pressure rolling shaft and the extrusion rolling shafts; the flocking filter belt is also internally provided with a plurality of tension rolling shafts used for enabling the flocking filter belt to be in a tensioning state; the circumferential surface of the pressure rolling shaft has a concave-convex structure of a gear. The concave and convex rolling shaft pressure device is simple in structure, good in dehydration effect, good in mud cake stripping effect, little in sludge residue, not easy to block and small in cleaning water quantity, and thus reducing secondary pollution.
Description
Technical field
The present invention relates to a kind of sludge dehydration device of filter press, relate in particular to the concavo-convex roller bearing of belt filter press and suppress device.
Background technology
Mud is the inevitable outcome after sewage treatment plant and sewage plant sewage disposal, after the mud entered environment of not disposing through fine processing, will bring secondary pollution directly to water body and atmosphere, ecological environment and the mankind's activity also will be formed to serious threat, therefore, mud is very prudent on processing.Sludge dewatering is that primary, the concentrated or digested sludge of liquid state is removed to moisture, is converted into a kind of method for sludge treatment of semisolid or solid-state clod.Moisture percentage in sewage sludge after dehydration can be reduced to 80 50 percent to percent, depending on the character of mud and sediment and the usefulness of dehydration equipment.The mud pressurizing and dehydrating of the high-moisture percentage producing in sewage disposal process, becomes the mud cake that solid content is high, for the realization of the follow-up disposal of mud provides condition.On equipment, there are plate and frame sludge dewatering equipment, belt mud dewatering equipment, Centrifugal sludge dehydration machine, folded formula sludge dewatering equipment and spiral pressing dehydrator, wherein belt mud dewatering equipment is because its price is lower, technology is relatively ripe, thereby use commonplace, it is carrying sludge blanket secretly by the strainer of upper and lower two tensionings, from the roll-in cylinder of a succession of regular arrangement, S-shaped process, rely on the tension force of strainer itself, formation is to the squeezing of sludge blanket and shearing force, capillary water in sludge blanket is squeezed out, thereby realize sludge dewatering.But because it uses traditional strainer, easily result in blockage, on it, mud is residual more, need a large amount of water to clean, cause secondary pollution.
Summary of the invention
For above-mentioned defect, the object of the present invention is to provide a kind of simple in structurely, dehydrating effect is good, and mud is residual few, is difficult for stopping up, and cleans discharge reduction, reduces the concavo-convex roller bearing of belt filter press of secondary pollution and suppresses device.
The technical solution adopted in the present invention is for this reason:
Comprise planting mao strainer and suppressing roller bearing of ring-type, described arc surface both sides of suppressing roller bearing are respectively equipped with initiatively roller bearing of a driven roller bearing and, suppress roller bearing below and be provided with some extruding roller bearings, the described mao strainer of planting is enclosed within on driven roller bearing, active roller bearing and extruding roller bearing and suppresses roller bearing and can push planting mao strainer formation with extruding roller bearing, plant and in mao strainer, be also provided with some tensioning roller bearings and make it in tensioning state, described in suppress the concaveconvex structure that the periphery of roller bearing is gear.
The described diameter of suppressing roller bearing is greater than the initiatively diameter of roller bearing, driven roller bearing and extruding roller bearing.
Advantage of the present invention is:
1, the present invention adopts the direct way of contact of roller bearing to realize to suppress dehydration mode and replaces traditional continuous many roller bearings of reducing S type noncontact tensioning dehydration mode, for improving sludge dewatering effect, can establish multistage in system; By adjusting, suppress the gap of roller bearing and periphery extruding roller bearing, can realize mud in strainer is squeezed in various degree.
2, the periphery of suppressing roller bearing is made as to the concaveconvex structure of gear type, is convenient to charging, reduce the contact area of itself and periphery extruding roller bearing simultaneously, reach the object that improves squeeze pressure.
3, adopt and to plant a mao strainer and replace traditional strainer, this plant a mao strainer have filter efficiency high, clean easily and the advantage such as long service life.At concentrated station, owing to there being cilium to stand on base cloth, the percent opening of base cloth is large, and filtrate can be filtered smoothly in a large number, and the coefficient of friction of piloerection before not pushing is maximum, catches sludge quantity many, and is difficult for leakage.At press filtration station, filter pressure increase makes cilium lie low toward equidirectional, increases the density on base cloth surface to prevent mud seepage, even depress adding, still can rely on the capillarity of cilium, continue filtering means dehydration, effectively solve mud side leakage situation, at mud extraction station, the cilium reinstatement of can standing immediately, mud cake can be upspring and be peeled off completely, mud cake is peeled off effective, and the upper mud of hair end is residual few, is difficult for stopping up, clean the water yield and relatively reduce, reduce secondary pollution.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Fig. 2 is traditional mechanism schematic diagram.
In figure, 1 is to plant a mao strainer, the 2nd, suppresses roller bearing, the 3rd, driven roller bearing, the 4th, and initiatively roller bearing, the 5th, pushes roller bearing, the 6th, tensioning roller bearing.
The specific embodiment
The concavo-convex roller bearing of belt filter press is suppressed device, comprise planting mao strainer 1 and suppressing roller bearing 2 of ring-type, described arc surface both sides of suppressing roller bearing 2 are respectively equipped with initiatively roller bearing 4 of a driven roller bearing 3 and, suppress roller bearing 2 belows and be provided with some extruding roller bearings 5, the described mao strainer 1 of planting is enclosed within on driven roller bearing 3, active roller bearing 4 and extruding roller bearing 5 and suppresses roller bearing 2 and can push planting mao strainer formation with extruding roller bearing 5, plant and in mao strainer 1, be also provided with some tensioning roller bearings 6 and make it in tensioning state, described in suppress the concaveconvex structure that the periphery of roller bearing 2 is gear.
The diameter of suppressing roller bearing 2 of the present invention is greater than the initiatively diameter of roller bearing 4, driven roller bearing 3 and extruding roller bearing 5.
