[0002] As the inevitable product of sewage treatment, sludge rational utilization not only can change waste into treasure, but also can increase economic benefits, and sludge treatment and disposal has important significance to protect and improve urban ecological environment. In the aspect of popularizing sludge land utilization, many regions have encouraged sludge generated by urban sewage treatment plant to be used as fertilizer or soil conditioner after being treated by aerobic fermentation, for land greening, garden construction, abandoned mine and non-agricultural saline-alkali soil and sandy land. The effect of aerobic fermentation is closely related to the moisture content of raw materials, and usually water is added to adjust the moisture content of the stack. When the stack is too large, the water adding method consumes manpower on one hand, and it is difficult to make the moisture content uniform by turning over on the other hand. After sludge treatment, it is divided into two categories: one is sludge with very high moisture content, and the other is dry material for landfill or incineration.

Detailed Implementation

[0018] Example 1:

[0019] like Figures 1-3 As shown, a moisture regulation device for urban sludge composting includes a first mixing container 1 and a second mixing container 2. The bottoms of the first mixing container 1 and the second mixing container 2 are respectively connected to a first spiral conveying pipe 6 and a second spiral conveying pipe 7. The first spiral conveying pipe 6 and the second spiral conveying pipe 7 intersect to form a mixing section 8. The mixing section 8 is provided with a third spiral conveying pipe 10 for discharging the mixed material. The mixing section 8 is provided with a drive motor 9, which drives the third spiral conveying rod 14 inside the third spiral conveying pipe 10 to mix the material.

[0020] Sludge with different moisture contents, weighed according to the ratio, is placed in the first mixing container 1 and the second mixing container 2 respectively. For example, sludge with a moisture content of 90% is placed in the first mixing container 1 and dry sludge without water is placed in the second mixing container 2. The two are put in according to the weight ratio. The third spiral transmission rod 14 driven by the drive motor 9 mixes the two materials, thereby outputting sludge with the target moisture content.

[0021] The outlet end of the aforementioned third spiral conveying pipe 10 is provided with a collection box 11.

[0022] The bottom of the first mixing container 1 and the second mixing container 2 are both equipped with mixing drive stirring motors 3, and the two mixing drive stirring motors 3 drive the stirring drive body 4 in the first mixing container 1 and the second mixing container 2 respectively.

[0023] The first spiral conveying pipe 6 and the second spiral conveying pipe 7 are respectively provided with a first spiral conveying rod 12 and a second spiral conveying rod 13.

The pipe diameter of the first and second spiral conveying pipes 6 and 7 and the spiral lead of the first and second spiral conveying rods 12 and 13 are set according to the ratio of the desired water content of the output sludge. The two different sludge are conveyed in the first and second spiral conveying pipes 6 and 7, which can ensure that the output sludge has the set water content.
