Further, the driving device is a motor.

Further, the level of the first discharging hole 42 is lower than the level of the first feeding hole 41.

In the embodiment, the driving device is specifically a motor, an output shaft of the motor is fixedly connected with the stirring blades 3, and when the motor is started, the stirring blades 3 can rotate along with the motor; the first discharge port 42 is disposed below the first inlet 41, and facilitates the concentrated slurry to be discharged from the mixer drum 4 in time without being diluted by the slurry just entering the mixer drum 4 for a long time.

Further, the mixer 1 includes: the spiral pipe comprises a first pipe body 11, a second pipe body 12, a first spiral sheet 13 and a second spiral sheet 14, wherein the direction of rotation of the first spiral sheet 13 is opposite to that of the second spiral sheet; the first spiral piece 13 is fixedly connected to the inner wall of the first pipe body 11, the second spiral piece 14 is fixedly connected to the inner wall of the second pipe body 12, and the first pipe body 11 is detachably connected with the second pipe body 12; a plurality of auxiliary material inlets 111 communicated with the first pipe body 11 are formed in the outer wall of the first pipe body 11, a second feeding port 112 for introducing slurry is formed in one end of the first pipe body 11, and a second discharging port 113 for outputting the primarily mixed slurry is formed in the other end of the first pipe body 11; a third feeding port 121 for receiving the primarily mixed slurry is arranged at one end of the second pipe body 12, and a third discharging port 122 for outputting the fully mixed slurry is arranged at the other end of the second pipe body 12; the third discharge hole 122 is connected with the other end of the conveying pipeline 5.

In practical application, the second feeding port 112 is connected with a pipeline for conveying slurry which is not mixed yet, and the auxiliary material inlet 111 is connected with a flocculant conveying pipeline; the slurry flows into the first pipe body 11 from the second feeding port 112, and the flocculating agent flows into the first pipe body 11 from the plurality of auxiliary material inlets 111; under the action of the conveying power provided by the inside of the slurry pipeline and the first spiral sheet 13, the slurry and the flocculating agent are initially mixed in the first pipe body 11; then, under the action of the conveying power provided by the inside of the slurry pipeline and the second spiral sheets 14, the slurry and the flocculating agent are fully mixed in the inside of the second pipe body 12, and finally flow into the conveying pipeline 5 from the third discharge port 122 and further flow into the stirring barrel 4. In practical application, according to actual need, first body 11 and second body 12 can be provided with a plurality ofly, and the mud carries out intensive mixing through a plurality of first bodies 11 and second body 12.

Further, the first helical flight 13 and the second helical flight 14 are both of an integral helical structure.

As shown in fig. 3: the first spiral sheet 13 and the second spiral sheet 14 are both of an integrated spiral structure and are formed by splicing a plurality of short spiral sheets; the benefits of this arrangement are: when the first spiral piece 13 is welded on the inner wall of the first pipe body 11 and the second spiral piece 14 is welded on the inner wall of the second pipe body 12, the integrated type is firmer than the split type, and the mud impact resistance of the first spiral piece 13 and the second spiral piece 14 is stronger.

Further, the outward rotation of the first spiral piece 13 to the inward rotation of the first spiral piece 13 is inclined toward the second discharge port 113 of the first pipe 11.

Further, the outward rotation of the second spiral piece 14 to the inward rotation of the second spiral piece 14 is inclined toward the third discharge hole 122 of the second pipe body 12.

As shown in fig. 2 and 3: the outward rotation of the first spiral piece 13 is inclined towards the inward rotation of the first spiral piece 13 and is inclined towards the direction of the second discharge hole 113; in this embodiment the first flights 13 are arranged in a left-handed configuration, and when the mixture of slurry and flocculant impacts the surface of the first flights 13, the mixture will rotate to the left and the peripheral mixture will be pushed towards the centre due to the blocking action of the first flights 13, and initial mixing will take place.

As shown in fig. 2 and 3: the first spiral sheet 13 and the second spiral sheet 14 are not connected, and a section of non-spiral-sheet pipeline space exists between the first spiral sheet and the second spiral sheet; when the mixture flows out of the second outlet 113, it is no longer blocked by the first screw 13, and the central mixture is pushed rapidly to the periphery.

Because the interior of the first tube 11 and the interior of the second tube 12 are not provided with the commonly used screws, the interior of the first tube 11 and the interior of the second tube 12 have larger spaces, and even if the slurry contains sundries such as waste cloth and plastic, the material blocking phenomenon cannot easily occur; meanwhile, the electric energy is saved because the screw is cancelled.

Further, the cross-section of the first spiral sheet 13 and the cross-section of the second spiral sheet 14 are both polygonal.

As shown in fig. 2 and 3: the polygonal structure not only increases the connection area of the first spiral sheet 13 and the inner wall of the first pipe body 11 and the connection area of the second spiral sheet 14 and the inner wall of the second pipe body 12, but also enables the slurry and the flocculating agent to be mixed more uniformly.

In summary, in the slurry concentration and separation device according to the embodiment of the present invention, the first spiral piece 13 is disposed on the inner wall of the first pipe 11, and the second spiral piece 14 is disposed on the inner wall of the second pipe 12, so that a common screw structure can be eliminated, thereby not only saving electric energy, but also reducing the probability of slurry jamming; the slurry concentration and separation device is an environment-friendly slurry concentration and separation device which is used for stirring and concentrating in the stirring barrel 4 and then discharging the concentrated slurry.

The above description is only a preferred embodiment of the present invention, the present invention is not limited to the above embodiment, and there may be some slight structural changes in the implementation, and if there are various changes or modifications to the present invention without departing from the spirit and scope of the present invention, and within the claims and equivalent technical scope of the present invention, the present invention is also intended to include those changes and modifications.
