Embodiment 1

[0040] refer tofigure 1 , figure 2 , image 3 and Figure 4 A kind of river course silt solidification device shown comprises a base 1, a water tank 2 is installed on the base 1, a frame 3 is welded on the base 1, a dispersion tank 4 is supported by the frame 3, the The upper end of the dispersion tank 4 is provided with a lower hopper 5, a flange 6 is connected between the dispersion tank 4 and the lower hopper 4, and a water separating ring 7 is clamped in the flange 6, and a water separation ring 7 is arranged in the water tank. 2, a booster water pump 211 is installed, and a booster water pipe 212 is connected between the booster water pump 211 and the water distribution pipe 7, and a pressure gauge 232 is installed on the booster water pipe 212, and the booster water pump 211 is connected to the water distribution pipe 7. A water supply pipe 213 is connected between the water tanks 2, and a water inlet pipe 214 is connected to the water tank 2. The water distribution r...

Embodiment 2

[0042] refer to Figure 5 and Image 6 As shown, the difference between it and Embodiment 1 is that the coarse filtration device 9 includes a horizontal pipe 901, the bottom of the horizontal pipe 901 is provided with a water outlet tank 902, and a collector is provided below the horizontal pipe 901. A water tank 903, a right-angle connector 904 is welded between the water collection tank 903 and the horizontal pipe 901, a water pipe 905 is arranged at the bottom of the water collection tank 903, and the lower end of the water pipe 905 is inserted into the water tank 2; A filter cloth 906 is wound on the horizontal tube 901, and the filter cloth 906 is wound with multiple turns; two clamps 907 for fixing the filter cloth 906 are installed outside the horizontal tube 901; as we The sludge is washed away, and the water content in the sludge increases. At this time, part of the water can be exported by gravity to reduce the working pressure of the dehydration tank.

Embodiment 3

[0044] refer to Figure 7 As shown, it differs from Embodiment 1 in that an auger 122 for feeding downwards is welded on the outside of the axis tube 12, and the auger 122 fits the inner wall of the dehydration tank 10; When the dragon 122 rotates, it will drive the sludge in the dehydration tank to realize the downward extrusion and dehydration of the sludge; at the same time, the auger 122 can also prevent the sludge from accumulating in the dehydration tank, and avoid the situation that the sludge cannot be squeezed downward for dehydration.

Abstract

The invention discloses a riverway sludge solidification device and a riverway sludge solidification method. The device includes a base, wherein a water tank is mounted on the base; a rack is welded on the base; a dispersion tank is supported by the rack; the upper end of the dispersion tank is provided with a blanking hopper, a flange is connected between the dispersion tank and the blanking hopper, a water distribution ring is clamped in the flange, a booster water pump is arranged on the water tank, a booster water pipe is connected between the booster water pump and the water distributionpipe, and a pressure gauge is arranged on the booster water pipe. The device and method can effectively realize sludge solidification, and have the advantages of lower treatment cost and higher treatment efficiency.

Description

technical field [0001] The invention relates to a river channel silt solidification device and a solidification method. Background technique [0002] In recent years, with the progress of urban ecological civilization construction, the problem of water pollution has become increasingly prominent. Therefore, comprehensive treatment of urban water environment and comprehensive treatment of river and lake sediment pollutants are imminent. The amount of dredging of urban river and lake silt is often huge, and with the increasing scale of the city, the urban land space is becoming increasingly tight, and large-scale dredging earthwork is landed, which will easily cause secondary pollution to the surrounding environment. A large amount of land for urban construction. [0003] The resource utilization of dredged sludge is an effective way to solve dredged sludge in rivers and lakes. The existing sludge disposal schemes mainly include natural drying, chemical solidification, mechan...
