The advection type sedimentation tank is the earliest sedimentation equipment, the operation is stable, the treatment effect is good, but the tank body has large volume and large floor area, and cannot be widely applied to large cities with tight land. With the continuous progress of sewage treatment technology, the treatment capacity of the inclined plate and inclined tube sedimentation under the same condition can be 3-10 times higher than that of a common horizontal sedimentation tank, and the floor area is 3-5 times smaller than that of the horizontal sedimentation tank.

At present, most of sedimentation equipment applied to engineering is a common inclined plate or inclined tube device, and some defects are also found in the practical application of the sedimentation equipment: more fine particles leak from equipment in the sedimentation process, so that the solid-liquid separation effect of a sedimentation tank is reduced; and a water collecting device is required to be arranged between the two sloping plates. The distance between the two inclined plates cannot be too small, resulting in a limited settling area. The sedimentation tank body is uneven in water distribution and collection, flocs enter the inclined plate along the way, the end part of the sedimentation tank body is far away, the rear part of the sedimentation tank body is far away, the sludge concentration at the end part of the sedimentation tank body is higher than that at the rear part of the sedimentation tank body, the sludge accumulation phenomenon on the inclined plate at the end part of the sedimentation tank body can occur, and the sedimentation tank body needs to be frequently cleaned.

Therefore, a sludge settling device is provided to solve the defects in the prior art.

Detailed Description

The principles and features of this invention are described below in conjunction with the following drawings, which are set forth by way of illustration only and are not intended to limit the scope of the utility model.

Example 1

As shown in fig. 1-3, the present embodiment provides a sludge settling device, which includes support tubes 1, V-shaped inclined plates 2 and vertical plates 3, wherein the shape of the support tubes 1 is cylindrical tubes and rectangular tubes, and certainly not limited to other shapes, the number of the support tubes 1 is 8, two support tubes 1 are arranged at intervals to form support tube groups, 4 support tube groups are arranged in parallel at intervals, 5V-shaped inclined plates 2 are fixedly arranged between two adjacent support tube groups, 5V-shaped inclined plates 2 are arranged in a stacked manner along the length direction of the support tubes 1, the V-shaped inclined plates 2 are connected with the corresponding support tubes 1 through the vertical plates 3, and the number of the specific support tubes 1 and V-shaped inclined plates 2 is determined according to actual requirements.

The rivers can evenly flow in when V type swash plate 2, and the suspended particles thing sinks perpendicularly under the action of gravity, separates the flocculating constituent that will deposit under the unchangeable prerequisite of rivers direction, and the alum blossom that will sink can not appear and is stirred by rivers and suspend in aqueous again, has realized water course and mud way in time separation. The embodiment selects a rectangular pipe with the side length of 0.2m or a circular pipe with the radius of 0.1m, the length of the pipe is 1m, the vertical height of the inclined plate is 50mm, the height of the sludge discharge port is 15mm, and the design of the gradient of 5% is adopted, so that the area of the sediment is increased, and the sedimentation distance is shortened. When sewage treatment is carried out, the slopes of the inclined plates at different angles can be selected according to different water body characteristics, so that the sedimentation efficiency is higher.

The working principle is as follows:

form the mud mouth between stay tube 1 and the V type swash plate 2, and form the gliding passageway between the riser 3, muddy water downward flow's in-process simultaneously, the mud that deposits on V type swash plate 2 receives gravity, rivers drag force, centrifugal force inertial force and V type swash plate 2's supporting force effect, constantly collect to the V type swash plate 2 outside, slide along the outside limit at V type swash plate 2 lower extreme, finally form the clear water district after sinking in the inboard of V type swash plate 2 lower extreme, the clear water just gets into water collecting device along V type swash plate 2. Therefore, mud and water can be thoroughly separated on the inclined plate, and the small water collecting holes are not easy to block.

Has the advantages that: the sewage passes through the V-shaped inclined plate 2, and the clean water enters the water collecting device along the V-shaped inclined plate 2. The suspended solid deposits along gliding passageway perpendicularly downwards, and suspended solid gliding speed obtains promoting, reduces the number of times of washing to the mud discharging opening, reduces the energy consumption. The water is at the in-process of flow through V type swash plate 2, and the suspended solid that deposits is constantly followed the mud mouth roll-off, and the slide distance is very short, and the swash plate is certain slope, makes effective area of precipitating increase to the settlement distance of suspended solid has been shortened.
