[0043] The inner wall of the shell 507 and the inner wall of the separation tank 1 are provided with an opening 517 for drawing impurities on one side, and the inner wall of the opening 517 is fixedly installed with a dust extraction groove block 518. The surface of the separation tank 1 is fixedly installed with a powerful dust collector 519 below the dust extraction groove block 518 for providing a drawing force, and the output end of the powerful dust collector 519 is fixedly connected with the surface of the dust extraction groove block 518.

[0044] The working principle of the above embodiment is:

[0045] When the device is used, the sugar powder production wastewater that needs to be separated is added into the separation tank 1 through the feeding pipe 13. The overall liquid is observed to be located at the half of the filter arc net plate 503 by using the glass plate 19, and the addition of the sugar powder production wastewater is stopped. After the addition of the sugar powder production wastewater is completed, the impurities in the sugar powder production wastewater can be removed;

[0046] After the sugar powder production wastewater is added, the first gear 301 is driven to rotate by the reduction motor 2, and the stirring groove rod 4 in the second gear 302 is driven to rotate by the first gear 301. The stirring groove rod 4 rotates to drive the stirring blocks 7 on the mixing cross rod 6 to stir the liquid in the separation tank 1, so as to ensure that the plant fibers in the sugar powder production wastewater float out. Because the stirring blocks 7 are elliptical, the liquid on the edge of the ellipse will generate local vortex due to the speed difference between the major axis and the minor axis. Especially near the "tip" of the elliptical block, the liquid flow rate suddenly changes to easily cause disturbance, which can ensure that the fiber waste in the liquid sugar powder production wastewater in the separation tank 1 is better separated out. When the stirring groove rod 4 rotates, the rotating blade 12 is driven to rotate by the connecting shaft block 11. The rotating blade 12 cooperates with the guiding effect of the guide cylinder 8 to ensure that the liquid has a downward pushing trend. When the downward liquid contacts the drop chute body 15, some impurities that are not soluble in water in the internal liquid will enter the bottom of the separation tank 1 through the taper opening 1501 on the drop chute body 15. Under the structure of the taper opening 1501 from large to small, the problem of lifting the impurities at the bottom of the separation tank 1 can be avoided. When the liquid collides with the drop chute body 15, it will run to both sides of the connecting cylinder 803 under the action of the inclined inner wall of the drop chute body 15, and be upwardly turbulent by the connecting vertical opening 804 on the taper cylinder 802. The rotating blade 12 forms an axial flow effect, which can ensure that the large particles of impurities that are not soluble in water are transported to the bottom of the separation tank 1. The liquid with impurities at the bottom of the drop chute body 15 will be uniformly discharged;

[0047] The rotating blades 12 of the device cooperate with the guide cylinder 8 to force the axial flow, and the rotating blades 12 are constrained by the guide cylinder 8 to generate a stable axial downward main flow and have sufficient kinetic energy to overcome local disturbances, ensuring that large particle impurities are continuously pressed to the tank bottom discharge chute 15. The device uses the upper large and lower small taper 1501 structure to form a physical barrier to prevent impurities from entering the bottom of the separation tank 1 and to prevent the bottom large particle impurities from floating up due to flow field fluctuations, ensuring that the impurities only enter and do not exit.

[0048] After the liquid in the device is removed from the large particle impurities, it will only be turned up through the connection vertical opening 804 opened on the tapered cylinder 802, rather than the full cross-section unordered upsurge, which avoids global flow field disorder. The device uses a speed reducer motor 2, which has a downward flow trend, and does not cause excessive agitation of the liquid surface, thereby continuously separating impurities in sugar powder production wastewater.

[0049] When the sugar powder production wastewater is added, some floating fiber impurities will be on the liquid surface. The stirring tank rod 4 rotates while driving the filter arc net plate 503 on the connecting ring 501 to rotate, thereby filtering the floating impurities on the liquid surface. This can filter and remove the floating impurities. After a period of rotation, the electric telescopic rod 504 can be started to remove the impurities on the filter arc net plate 503. When the electric telescopic rod 504 is started, the pressing block 506 will move downward, which will squeeze the self-resetting press switch 509, thereby starting the powerful dust collector 519. At this time, the suction shell 507 will generate suction force. Due to the downward movement of the electric telescopic rod 504, the double-toothed plate 510 will be driven to move downward through the movable block 505. At this time, through the rotation transmission of the plurality of connecting teeth 512, the connected moving tooth plate 513 can drive the connecting ring 501 on the moving block 514 to move upward. In this way, the filter arc net plate 503 will move upward away from the liquid surface. The filter arc net plate 503 will be squeezed when it contacts the suction shell 507, so that the filter arc net plate 503 is in an unfolded state. The impurities in the filter arc net plate 503 will be sucked away by the collection port 508 on the suction shell 507, thereby removing the impurities on the filter arc net plate 503. After the cleaning is completed, the electric telescopic rod 504 is reset. Under the rotation force of the return spring 520, the filter arc net plate 503 can be repositioned in an inclined state to facilitate the filtration and removal of impurities on the liquid surface. After several times, the impurities on the upper side of the liquid surface and the impurities insoluble in water can be completely removed. At this time, the treated sugar powder production wastewater can be discharged through the liquid outlet pipe 14, thereby ensuring the separation effect of solid waste pollution in wastewater. The separated solid waste pollution can also be used for thermal power generation, which not only ensures energy saving effect, but also ensures environmental protection effect of energy utilization by utilizing the combustion of plant fibers. The device highlights the innovative structure and does not make excessive elaboration on the existing mature technology.

[0050] The mounting mode, the connecting mode or the setting mode disclosed in the embodiment are common mechanical connecting modes, and can be implemented as long as the beneficial effects can be achieved. In addition, the electrical components appearing in the embodiment are electrically connected with the master controller and the power supply. The master controller can be a conventional known device such as a computer which plays a control role. A person skilled in the art can realize the control of the electrical components through simple programming. The existing disclosed power connection technology also belongs to the common knowledge in the field. Therefore, the specific structure composition and working principle of the embodiment will not be described in detail.
