Detailed Description

The following will describe in further detail a novel device for soil remediation according to the present invention with reference to specific embodiments and accompanying drawings.

As shown in fig. 1 and fig. 2, in a preferred embodiment, the novel device for soil treatment of the present invention comprises a frame 1, and a stirring tank 2 and a sludge dewatering machine 3 which are arranged on the frame 1, wherein a screw shaft 21 and a first motor 22 for driving the screw shaft 21 to rotate are arranged at the bottom of the stirring tank 2; the top of the stirring box 2 is provided with a stirring blade 23 and a second motor 24 for driving the stirring blade 23 to rotate; the sludge dewatering machine 3 is obliquely arranged, a feeding port 32 is arranged at a lower position close to one end of the stirring box 2, and a discharging port 31 is arranged at a higher position far away from one end of the stirring box 2; a water collecting tank 4 is arranged below the sludge dewatering machine 3, and a filter sieve 8 is arranged in the water collecting tank 4. When the sludge stirring device is used, the first motor 22 drives the screw shaft 21 to rotate, sludge precipitated at the bottom of the stirring box 2 is stirred and conveyed to the middle upper part of the stirring box 2, and the second motor 24 drives the stirring blade 23 to rotate, so that sludge at the middle upper part of the stirring box 2 is stirred, and thus, the sludge in the stirring box 2 is prevented from being precipitated at the bottom in a large amount; sludge slurry of stirring in agitator tank 2 gets into sludge dewaterer 3 through pan feeding mouth 32 and dewaters, and in the dehydration process, there is a small amount of mud to spill from 3 gaps of sludge dewaterer, falls into water catch bowl 4 in, filters once more by filter sieve 8 in the water catch bowl 4, and the mud that spills is most to be sieved by filter sieve 8 and is removed, and mud content is low in the sewage that finally deviates from.

As a preferable technical solution, in this embodiment, the sludge inlet 25 is disposed at the bottom of the stirring tank 2, so that sludge can flush bottom sediments when flowing in, the sludge outlet 26 is disposed at the top of the stirring tank 2, the sludge outlet 26 is connected to the material inlet 32 of the sludge dewatering machine 3, and sludge overflows from the top into the sludge dewatering machine 3 after being sufficiently stirred in the stirring tank 2; in order to improve the dehydration effect and enhance the soil treatment efficiency, the top of the stirring box 2 is also provided with a chemical feeding pipe 27, and the chemical for treating the sludge can be added through the chemical feeding pipe 27 and is fully stirred.

In the preferred embodiment, the water collecting tank 4 is disposed in an inclined manner, and the inclined direction of the water collecting tank 4 is the same as the inclined direction of the sludge dewatering machine 3, and the bottom of the water collecting tank 4 is further provided with a vibration motor 5. The 4 slope settings of water catch bowl can discharge sewage fast, avoids sewage to spill over and pollutes the workshop, and shock dynamo 5 can flow with higher speed sewage, and improves filter sieve 8's filtration efficiency, avoids filter sieve 8 to go up mud and piles up, makes in the filter sieve 8 mud continuously to lower one side slip.
