Sewage suction equipment and sewage suction operation method for cleaning river sludge

Abstract

The invention discloses a sewage suction equipment for cleaning river sludge and a sewage suction operation method thereof, comprising a sewage suction boat, an elevator and a sewage suction execution device, the sewage suction execution device can be lifted and lowered on the sewage suction boat through the elevator, and the sewage suction boat It has a sludge storage bin, and the bin mouth is equipped with a sludge solid impurity screening mechanism; the sewage suction actuator includes a sewage suction pump, a sludge conveying pipe group, a sewage suction mixer and a driving mechanism; the elevator drives the sewage suction actuator to descend to make The inverted conical sewage suction shell of the sewage suction mixer and the sludge mixing and cutting frame gradually penetrate into the river sludge, and the driving mechanism drives the vertical sewage guide pipe and drives the sludge mixing and cutting frame to rotate to stir the river sludge and clean the river. Weeds in the sludge are cut. The invention can be used for sewage suction and cleaning operation of river channel sludge, and has good sewage suction effect and high efficiency.

Description

technical field [0001] The invention belongs to the technical field of river channel pollution control, and in particular relates to a sewage suction device for cleaning river channel sludge and a sewage suction operation method thereof. Background technique [0002] Existing sewage suction devices for river sludge cleaning have the following disadvantages: [0003] 1. It only has the function of sewage suction, and does not have the function of removing solid impurities from river sludge: because river sludge contains solid impurities, such as some common pebbles, solid impurities need to be removed after river sludge is sucked out, and there is no These solid impurities are screened out during the sewage suction process, resulting in cumbersome steps for subsequent river sludge treatment and poor versatility; [0004] 2. Poor sewage suction effect and low efficiency: The long-term accumulation of river sludge makes the river sludge sticky and viscous. The existing sewage ...

Problems solved by technology

[0003] 1. It only has the function of sewage suction, and does not have the function of removing solid impurities from river sludge: because river sludge contains solid impurities, such as some common pebbles, solid impurities need to be removed after river sludge is sucked out, and there is no These solid impurities are screened out during the sewage suction process, resulting in cumbersome steps for subsequent river sludge treatment and poor versatility;

[0004] 2. Poor sewage suction effect and low efficiency: The long-term accumulation of river sludge makes the river sludge sticky and viscous. The existing sewage suction device can carry out the sewage suction operation without destroying the sticky stickiness of the river sludge in advance. , it is difficult to completely suck out the river sludge. In addition, the weeds growing in the river sludge have a certain mud-fixing property to the river sludge (analogous to the solidity of plants to the soil). If these weeds are not destroyed, then It will increase the difficulty of the sewage suction operation, resulting in very low sewage suction efficiency
