Abstract
The present invention provides a new sludge suspension bed mud funnel inclined plate settler, composed of an upper part and a lower part. The upper part is the inclined plate, the lower part is the mud funnel part, a stable sludge suspension bed is formed in the mud funnel when the mud funnel has a large height, the hydraulic discharge of the settler is evidently improved since mud of the suspension bed having a catching and collision action to alum grain in the water, hydraulic discharge is above 3 times of the common inclined plate device.
Description
Patent of the present invention belongs to gravity solid, liquid separator.Be mainly used in fields such as water treatment, chemical industry.Usually the solid, liquid gravitational separation device is a sloping plate deposition equipment.This is made up of with the swash plate module that parallel downward-sloping supporting rib is connected and fixed formation numerous squares dull and stereotyped (swash plate) that tilt that are parallel to each other.Water or other liquid flow from bottom to top along swash plate and rib formation ramp way, and the solid particle vertical is deposited on the swash plate, and slides along swash plate, and clear water is flowed out by the swash plate upper end.This equipment has only the precipitation function, the function of not flocculating.
Patent of the present invention is under common inclined plate sedimentation device, adds a plurality of sludge funnels, and these sludge funnels are supported on the carriage of sedimentation basin, and is covered with sedimentation basin, and common inclined plate sedimentation device is supported on these sludge funnels.
Beneficial effect: the mud that drops on the swash plate is slipped in the sludge funnel.Because sludge funnel end opening size is far smaller than sludge funnel size suitable for reading, when so the water after the flocculation reaction flows into from the sludge funnel end opening, flow velocity is far longer than it from sludge funnel outflow flow velocity suitable for reading, can utilize the height that changes sludge funnel to change the size of sludge funnel end opening size.Because its end opening water inlet flow velocity is very big, and the mud that falls from sludge funnel is produced very strong jacking, some heavy mud flow out from sludge funnel, and light mud is then stayed in the sludge funnel.Mud in inclined plate sedimentation device under the precipitation is continuously to slide, and always has some light mud to stay in the sludge funnel, so the sludge concentration in the sludge funnel is in continuous increase.Because mud decrease speed heavy in the sludge funnel is big, light mud decrease speed is little, so under the situation of high concentration sludge, the collision probability of light, heavy mud has increased considerably, the mud yardstick is constantly grown up, and the mud of growing up flows out from sludge funnel again.When the mud in entering sludge funnel equated with the mud that flows out from sludge funnel, the concentration of mud then kept constant in the sludge funnel.From the inclined plate sedimentation device constant required time of sludge concentration the sludge funnel that brings into operation, with the size of sludge concentration size, sludge funnel in the sludge funnel and the sludge funnel end opening is large and small decides.The more little required time of big more its end opening size of sludge funnel is long more.Sludge concentration can decide with the upper and lower open area ratio of sludge funnel in the sludge funnel, is just decided by sludge funnel import water velocity.Mud can reach very high concentration in the sludge funnel.Just because of the sludge funnel sludge concentration is very high, so in sludge funnel, form the body refuse superposed layer of high concentration.When the water after the flocculation reaction will pass the body refuse superposed layer from the sludge funnel inlet when entering.Most granule alumen ustum in the water are caught by mud granule, or length flow in the inclined plate sedimentation device on top to enough big yardstick.The effluent quality and the water yield of inclined plate sedimentation device have so just been improved greatly.Its improvement degree then depends on sludge concentration in the sludge funnel.Should be noted that sludge funnel is high more, the slime layer in the sludge funnel is stable more.Sludge funnel hour, the suspension slime layer in the sludge from sedimentation tank process in the sludge funnel is destroyed, and its spoil disposal rear overhang mud scum slag blanket forms also very fast certainly.But in this case, device is under the unstable situation and works.Sludge funnel is high more, and the sedimentation basin height is big more, but the floating layer work in body refuse county is stable more, is not destroyed in the time of can reaching sludge from sedimentation tank.Its disposal ability is more than 3 times of common inclined plate sedimentation device.
Patent type of the present invention is characterised in that: it is by I, II two parts are formed, its top is inclined plate sedimentation device I, the bottom is rectangle or square sludge funnel device II, top inclined plate sedimentation device I is identical with common inclined plate sedimentation device, bottom sludge funnel device II is made up of a plurality of rectangles or square sludge funnel, it is suitable for reading big, young down, the gradient on sludge funnel inclined-plane should be greater than 50 degree, sludge funnel can be supported on the swash plate carriage, also can when building, sedimentation basin pond body directly be fixed on the sedimentation basin carriage, when sludge funnel is very high, sludge funnel should be fixed on the body of sedimentation basin pond, establish carriage on it again, inclined plate sedimentation device II is supported on this carriage.

Embodiment:
Top sloping plate unit I is welded into the swash plate module by sheet plastic 1 and plastics rib 2 heat seals point and forms, and is identical with general inclined plate sedimentation device.Bottom II is made up of the funnel that a plurality of steel plates, corrosion resistant plate, fiberglass, plastic plate are made.Inclined plate sedimentation device I is supported on the sludge funnel device II, and sludge funnel device II is supported on the swash plate carriage, or really connects when the sedimentation basin body is built and be fixed on the body of sedimentation basin pond.Sludge funnel II is covered with the entire area of inclined plate sedimentation device I lower end.
Claims (2)
1. patent of the present invention is made up of two parts, and its top is inclined plate sedimentation device (I) (identical with common sloping plate unit), the sludge funnel device (II) that its underpart is made up of a plurality of big, following young sludge funnels (3) suitable for reading.
2. according to the requirement of power 1, sludge funnel device (II) can be supported on the sedimentation basin carriage, also can when the body of building sedimentation basin pond, directly be fixed on the swash plate carriage, when the height of sludge funnel device (II) is very big, it directly should be fixed on the body of sedimentation basin pond, the swash plate carriage is set thereon again, and inclined plate sedimentation device (I) supports on this carriage.
