[0001] The utility model relates to the technical field of sewage treatment, in particular to a high-efficiency vortex sludge concentrating device. Background Art

[0002] With the current development of the domestic economy, the problem of freshwater shortage in China has become particularly prominent, and the sustainable development of the economy is limited by water shortage and water quality deterioration. From the perspective of sustainable development, the best way to achieve these goals is to save water in depth. For some special areas, it is even more necessary to implement "zero discharge" of wastewater in the whole plant. The concentration reduction unit is an effective means to increase the ion concentration of wastewater, reduce the amount of evaporation water for curing, and reduce the load of the terminal curing system.

[0003] At present, traditional concentration and reduction units mainly include membrane concentration and multi-effect evaporation concentration, but each technology has its own shortcomings. Membrane concentration has high operating costs and high pretreatment requirements; multi-effect evaporation process equipment requires large investment, complex operation, and easy clogging.

[0004] Therefore, it is necessary to provide a high-efficiency vortex sludge thickening equipment to solve the above technical problems. Utility Model Content

[0012] As a preferred technical solution of the utility model, three legs are evenly arranged at the lower end of the reaction cylinder.

[0013] Compared with the prior art, the beneficial effects of the utility model are:

[0014] The utility model discloses a high-efficiency vortex sludge thickening device. The utility model provides a guide plate on the inner wall of the vortex device. The sewage introduced through the mud inlet has a certain impact force. After the sewage is guided by the guide plate, a tangential force is generated to impact the vortex device, so that the vortex device rotates in a set direction to generate centrifugal force. Under the centrifugal force of the vortex device, the sludge with a larger mass in the sewage is pushed to the inner wall of the vortex device and slides down downward. The clean water moves upward to achieve the effect of mud and water separation. The separation effect is good. An expansion port is provided on the top of the vortex device. When the sludge rotates in the vortex device, the expansion port can collect some residual particles. It is allowed to slide naturally to the mud storage area at the bottom of the reaction cylinder, which can greatly reduce the hydrodynamic disturbance of the vortex device to the static layer. A flushing port is opened on the outer wall of the reaction cylinder, and a constant pressure layer is opened in the reaction cylinder near the flushing port. The constant pressure layer makes the pressure in this area constant through automatic control, thereby ensuring that the water flow rate from the flushing port of the vortex device is controlled at a set value, so that the rotation speed of the vortex device is stable, and the sludge concentration effect is guaranteed. At the same time, the hydrodynamic force rotates inside the vortex device, and the hydrodynamic force offsets the lower hydrodynamic force after descending to the set area at the lower end of the vortex device, thereby not disturbing the sludge in the lower sludge accumulation layer to concentrate the sludge through water pressure.

During the rotation of the sludge, the cutting teeth 5 can be used to cut the block or linear impurities in the sludge to prevent the blockage caused by the large sludge blocks and the inability to be discharged. An expansion port 6 is provided on the top of the vortex device 3. When the sludge rotates in the vortex device 3, the expansion port 6 can collect some residual particles and make them naturally slide to the mud storage area at the bottom of the reaction tube 1, which can greatly reduce the hydrodynamic disturbance of the static layer of the vortex device 3.

[0027] A flushing port 12 is provided on the outer wall of the reaction cylinder 1, and a constant pressure layer 13 is provided near the flushing port 12 in the reaction cylinder 1. The constant pressure layer 13 keeps the pressure in this area constant through automatic control, thereby ensuring that the water flow rate of the vortex device 3 from the flushing port 12 is controlled at a set value, so that the rotation speed of the vortex device 3 is stable, thereby ensuring the sludge concentration effect. At the same time, the water force rotates inside the vortex device 3, and the water force offsets the lower water force after descending to the set area at the lower end of the vortex device 3, thereby not disturbing the sludge in the lower sludge accumulation layer and concentrating the sludge through water pressure.
