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

Abstract

The invention discloses sewage suction equipment for cleaning river channel sludge and a sewage suction operation method of the equipment. The sewage suction equipment comprises a sewage suction ship,an elevator and a sewage suction execution device, the sewage suction execution device is arranged on the sewage suction ship in a lifting manner through the elevator, the sewage suction ship is provided with a sludge storage bin, and a sludge solid impurity screening mechanism is arranged at a bin opening of the sludge storage bin. The sewage suction execution device comprises a sewage suction pump, a sludge conveying pipe group, a sewage suction stirrer and a driving mechanism; the elevator drives the sewage suction execution device to descend to enable an inverted conical sewage suction shell body of the sewage suction stirrer and a sludge stirring and cutting frame to gradually penetrate into the river sludge, and the driving mechanism drives a vertical sewage guiding pipe and drivesthe sludge stirring and cutting frame to rotate to stir the river sludge and cut weeds in the river sludge. The sewage suction equipment can be used for sewage suction and cleaning operation of riversludge, and has good sewage suction effects 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
