In this embodiment, preferably, the driving device 13 is mounted on the motor mounting beam 17 through connecting pieces such as screws and nuts, which is convenient for detachment.

The scraper stirring mechanism 15 is used to accelerate the reaction and granulation of the chemical agent and the mud, and to gently stir the granulated mud. Clean and scrape to prevent sludge from sticking to the tank body 11 and not flowing when the moisture content of the sludge is low after granulation. Wherein, when the scraper stirring mechanism 15 is stirring, the rotation speed is relatively slow, which is beneficial to granulation. Secondly, the fluctuation of the mud is not obvious, which can effectively reduce the mud film attached to the wall of the cylinder. In this embodiment, preferably, the rotation speed of the scraper stirring mechanism 15 is 3-5 rotations per minute. For example, it can be 3, 4, 5, etc. That is to say, as long as the rotation speed of the scraper stirring mechanism 15 is within the range of 3-5 rotations per minute, any value is sufficient.

The righting mechanism 21 is used to limit the displacement of the scraper stirring mechanism 15 in the horizontal direction so that it can work normally in the tank body 11 , and at the same time, it can also play a role in strengthening the strength of the scraper stirring mechanism 15 . For example, when the moisture content of the sludge is low, after granulation, the mud adheres to the tank body 11 and does not flow. At this time, the damping of the scraper stirring mechanism 15 is relatively large. If there is no strengthening of the protection of the centralizing mechanism 21, the scraper stirring Mechanism 15 is easy to break off from the middle part during the stirring process.

The liquid outlet of the static mixer 23 communicates with the slurry inlet 111 . When it is necessary to treat the sludge, the slurry added with chemicals enters the static mixer 23 from the liquid inlet end of the static mixer 23, and after rapid mixing and stirring in the static mixer 23, it flows from the inlet slurry through the liquid outlet. The port 111 flows into the tank body 11 and begins to granulate in the tank body 11. The mud begins to stratify. After the mud and water are separated, the water is collected and discharged from the water outlet 112. The mud accumulates at the bottom of the tank body 11 due to its own weight. The mud discharge port 113 gets rid of.

This embodiment also provides a sludge dewatering device 30 , as shown in FIG. 4 . The sludge dewatering device 30 includes: a medicine tank 31 and the three-dimensional granulator 10B described in the second embodiment.

In this embodiment, preferably, the drug outlet of the drug tank 31 communicates with the liquid inlet of the static mixer 23. When the sludge needs to be treated, the chemical agent flows into the static mixer from the drug outlet of the drug tank 31. In the mixer 23, after rapid mixing and stirring with the mud, the mud mixed with the chemical agent flows into the tank body 11 from the slurry inlet 111 through the liquid outlet, and starts to granulate in the tank body 11, and the mud begins to stratify. After being separated from the water, the water is collected and discharged from the water outlet 112 , and the mud accumulates to the bottom of the tank body 11 due to its own weight, and is discharged through the mud discharge port 113 .

Wherein, it should be understood that the three-dimensional granulator 10B in the sludge dewatering device 30 can also be replaced by the three-dimensional granulator 10A in the first embodiment. At this time, the medicine outlet of the medicine tank 31 It communicates with the slurry inlet 111 of the three-dimensional granulator 10A, and its principle of use is the same. In order to avoid redundancy, no more examples are given here.

The three-dimensional granulator includes: a vertically placed tank, a driving device, a scraper stirring mechanism, a centralizing mechanism, a static mixer, a motor installation beam, a valve, an escalator, and the like. The three-dimensional granulator adopts a vertically placed tank structure, which can not only increase the gravitational potential energy of the mud falling, facilitate the further mixing of mud and chemicals, so as to improve the separation effect of mud and water, but also effectively reduce the occupied area. land area. Secondly, use a scraper stirring mechanism with a relatively slow speed, for example, use a scraper stirring mechanism with a speed of 3-5 revolutions per minute to gently stir the mud in the tank, which can not only accelerate the reaction of chemical agents and mud, granulation etc. Moreover, the fluctuation of the mud is not obvious, which can effectively reduce the mud film attached to the wall of the cylinder.
