Description

A sediment removal mechanism of a slag removal device and its use and desilting method

technical field

The invention relates to drainage equipment, in particular to a silt removal mechanism of a slag removal device and a method for using and removing silt.

Background technique

Usually, the sedimentation, suspended pollutants and floating pollutants of large particles in the sewage can be intercepted by setting a slag net in the abandonment well. However, it cannot effectively intercept the silt and sand with smaller particles. Moreover, the existence of the slag net will cause the flow rate of sewage to slow down, resulting in easy accumulation of silt and pollutants behind the slag net.

The baffle device also includes a floating baffle, and the two ends of the floating baffle are slidingly matched with the two baffle slide rails respectively; the overall density of the floating baffle is lower than that of water;

When the water level in the abandonment well increases, the height of the floating baffle increases with the increase in the water level, preventing floating pollutants on the water surface from flowing into the outlet pipe.

Further, a liquid level detection device for the water outlet area is provided between the slag removal device and the water outlet pipe, and a liquid level detection device for the water inlet area is provided between the baffle device and the water inlet pipe.

Further, the lower end of the baffle slide rail is provided with a lower stop baffle; the lower stop baffle is lower than the upper end of the filter screen frame and higher than the lower end of the filter screen frame, specifically, it can be set as high At the water level on a sunny day.

When the water level in the abandonment well is not enough to make the floating baffle float up and be higher than the lower stop baffle, the lower end of the floating baffle abuts against the lower stop baffle, and the water flows on the liquid surface. The floating pollutants are blocked by the floating baffle;

When the water level in the abandonment well is lower than the lower stop baffle, the floating pollutants on the water surface flow into the filter screen.

Further, the desilting device is a stirring pump or an impact pump whose outlet end faces the outlet pipe.

When in the opening period, the desilting device starts to remove the silt between the slag removing device and the outlet pipe;

When in the closing period, the desilting device is closed.

The present invention is equipped with a slag removal device to effectively intercept the settlement of large particles in the sewage; the suspended pollutants and floating pollutants are blocked by a floating baffle, and when the liquid level drops, they are collected in the slag removal filter.

The slag filter screen cannot intercept small silt and sand particles, and because the slag filter screen intercepts sedimentation pollutants and suspended pollutants, the water flow velocity behind the filter screen of the slag removal device is slow, making the sediment and silt It cannot be effectively washed into the sewage pipe, and it is easy to cause the accumulation of silt and sand.

In the present invention, a desilting device is installed on the rear side of the slag filter screen, for example, a stirring pump is used to break up the silt into the water flow, or a shock pump is used to directly flush the silt into the outlet pipe, and the desilting device only needs to operate intermittently. The settled sediment and silt can be rolled up and then flow into the sewage pipe under the action of hydraulic power, which avoids excessive consumption of energy.
