Description

Technical Field

[0001] The utility model relates to the technical field of water treatment sedimentation, in particular to a short-distance inclined plate for a sedimentation tank. Background Art

[0002] Sedimentation tanks use the natural sedimentation of muddy water or the effect of coagulation and sedimentation to remove suspended matter in the water. According to the direction of water flow, they are divided into three types: horizontal flow, vertical flow and radial flow.

[0003] Inclined plate sedimentation tanks utilize Ha Zhen's "shallow sedimentation" principle to shorten the particle settling distance, thereby shortening the sedimentation time, and increasing the sedimentation area of ​​the sedimentation tank, improving the sedimentation efficiency. However, the water flow in existing inclined plate sedimentation tanks generally adopts the flow direction of water inlet at the bottom and water outlet at the top, resulting in uneven water distribution in the inclined plate sedimentation tank. At the same time, since the sedimentation efficiency of the sedimentation tank is proportional to the projected area of ​​the inclined plate on the bottom surface, the inclined plate inclined tube sedimentation tank does not fully utilize the shallow tank theory and does not maximize the sedimentation efficiency. In addition, in order to increase the sedimentation area, some existing inclined plates are blocked by sludge due to the small spacing between them, which affects the sedimentation efficiency. Utility Model Content

[0004] The utility model aims to overcome the defects of the prior art and provide a short-distance inclined plate for a sedimentation tank, which reduces the blockage of sludge in the sedimentation process and improves the sedimentation efficiency.

[0005] In order to achieve the above technical effects, the utility model provides a short-distance inclined plate for a sedimentation tank, wherein a plurality of mud discharge channels are evenly arranged in the horizontal direction in the sedimentation tank, and a plurality of sedimentation chambers are formed between adjacent mud discharge channels. The short-distance inclined plate includes:

[0006] Used to be arranged in a plurality of sets of inclined plate bodies in a one-to-one correspondence in a plurality of the sedimentation chambers, each set of the inclined plate bodies comprises a plurality of short-distance inclined plate pieces evenly arranged along the length direction of the mud discharge channel, and each of the short-distance inclined plate pieces is provided with a plurality of flow stabilizing ribs, and each of the short-distance inclined plate pieces comprises two pieces which are symmetrically connected at an angle and have an opening direction downward, and the angle range between the two pieces is 45° to 60°.

[0007] Preferably, a sealing plate is provided at the bottom of each group of the inclined plate bodies.

[0008] Preferably, the distance between two adjacent short-distance inclined plate pieces in each group of the inclined plate bodies ranges from 60 mm to 100 mm.

[0009] Preferably, a plurality of the flow stabilizing ribs are respectively fixedly mounted on the bottom of the two sheet bodies.

[0010] Due to the adoption of the above technical solution, the technical effects achieved by the utility model are:

[0011] 1) The flocculent impurities carried in the water are deposited on the surface of the short inclined plate in a parabolic trajectory, and quickly slide into the sludge discharge channel under the action of gravity. By setting the flow stabilizing ribs, the water flow can be prevented from disturbing the settled sludge.

[0012] 2) The sedimentation efficiency is improved, and the sedimentation efficiency is 1 to 2 times that of the traditional inclined plate.

[0013] 3) The height of the sedimentation tank can be reduced, effectively saving costs. The height of the sedimentation tank is 60% to 70% of the height of the sedimentation tank using traditional inclined plates. BRIEF DESCRIPTION OF THE DRAWINGS
