Description

A slant plate sedimentation tank

technical field

The utility model relates to the field of sewage treatment equipment, in particular to an inclined plate sedimentation tank.

Background technique

Sedimentation tank is a structure that uses sedimentation to remove suspended solids in water, and is widely used in wastewater treatment. The sedimentation tank has a variety of structural forms. Among them, the inclined plate sedimentation tank can greatly improve the sedimentation efficiency, shorten the sedimentation time and reduce the volume of the sedimentation tank because of the addition of a sloping plate in the tank. However, due to the small spacing between the inclined plates in the existing inclined plate sedimentation tank, after the sedimentation tank has been in operation for a period of time, or when the water quality and quantity change, its sedimentation efficiency and effluent water quality will be significantly reduced, resulting in serious mud accumulation and blockage between the inclined plates. , and even crush the sloping board.

Utility model content

The purpose of the utility model is to provide an inclined plate sedimentation tank, which can effectively solve the problems in the background technology.

The technical solution to achieve the above purpose is: a sloping plate sedimentation tank, including a tank body, the head end of the tank body is provided with a water inlet assembly, and the end of the tank body is provided with an overflow port and an overflow tank matched with the overflow port. It is characterized in that: a sloping plate assembly is arranged in the pool body, and the sloping plate assembly includes a plurality of sloping plates arranged in parallel, the middle parts of both ends of the sloping plates are movably connected with the pool body through the first rotating shaft, and the bottom sides of the sloping plates are respectively connected to each other. There are connecting rods, and the connecting rods are movably connected to the swash plate through the second rotating shaft. The middle part of the pool body is also equipped with a driving mechanism that drives the first rotating shaft at one end of the sloping plate located in the middle; the bottom of the pool body is provided with a plurality of V The bottom of the sludge hopper is equipped with a perforated sludge discharge pipe.

Further, a herringbone grille is installed in the pool body between the sludge hopper and the inclined plate assembly.

Further, the top of the pool body is provided with a plurality of high-pressure spray pipes arranged side by side, the high-pressure spray pipes are connected to the high-pressure water pump through the pipeline, and the spray pipes are respectively connected with high-pressure spray heads facing the swash plate assembly.

Further, the water inlet assembly includes a box body, one end of the box body is connected with a water inlet pipe, and the other end is provided with a water outlet connected to the lower part of the pool body, between the water inlet pipe and the water outlet are provided with staggered upper opening baffles and Lower opening bezel.

The beneficial effects of the utility model:

In the utility model, a high-pressure nozzle is arranged above the swash plate assembly, through which the mud accumulation and blockage on the swash plate are regularly washed, and at the same time, the driving mechanism drives the swash plate to rotate around the first rotating shaft at both ends to realize angle adjustment, so that the swash plate There is no dead angle to clean through the high-pressure nozzle, and at the same time, the mud accumulation can also be cleaned during the rotation of the swash plate.

The utility model can also directly drive the swash plate to swing back and forth through the driving mechanism, and realize the cleaning of mud accumulated on the swash plate under the action of the vibration force.

The setting of the herringbone grid can realize the preliminary separation of sludge and reduce the load of the inclined plate assembly, and the slope of the herringbone grid can make the sludge slide down and improve the separation effect.

Upper opening baffles and lower opening baffles are arranged alternately in the water inlet assembly, which reduces the flow speed of sewage and facilitates sludge settlement.
