[0022] Please refer to Figures 1-5 , the present utility model provides a technical solution: a circulating water structure of a light material water flotation machine, which includes a water tank 1 with a sewage outlet 5 opened at the bottom, a water supply pipe 3 installed on the left side of the inner cavity of the water tank 1, and a triangular filter box 7 installed on the right side of the inner cavity of the water tank 1; the front and rear sides of the filter box 7 are respectively connected with a circulating water outlet pipe 8, and the outer end of the circulating water outlet pipe 8 penetrates through the outer wall of the water tank 1; two conveying pipes 2 are respectively installed on both sides of the upper end of the water tank 1, one end of the two conveying pipes 2 is connected with the outer end of the circulating water outlet pipe 8, and the other ends of the two conveying pipes 2 are respectively connected with both ends of a flow divider 6. The flow divider 6 is installed in the water tank 1 and the water outlet of the flow divider 6 is directly opposite to the filter box 7.

[0023] The filter box 7 includes two side plates 14 arranged opposite to each other in the front and rear. The two side plates 14 are connected by a support frame, and a chain track is installed on the support frame, and a filter chain plate 15 is sleeved on the chain track.

Method flanges 10 connected to the conveying pipes 2 are respectively arranged on the front and rear sides of the main body. A partition 11 separating the front and rear is installed in the middle of the main body. A plurality of flow dividing grooves 13 are opened between the partition 11 and the method flanges 10.

[0026] A liquid level transmitter 4 is installed on the inner cavity side wall of the water tank 1 to monitor the water level change of the sorting water in the water tank 1.

[0027] In this embodiment, the circulating water structure device is installed on the frame, and the water outlet of the circulating water diverter 6 faces the direction of the light material conveyor.

[0028] A filter box 7 is arranged under the light material conveyor, that is, the water inlet of the circulating water; the circulating water outlet pipes 8 on both sides of the circulating water filter box 7 pass through the outer wall of the water tank 1 and the side plate 14 of the filter box 7 and enter the chamber in the filter box 7. During the operation of the equipment, under the action of the circulating water pump 9, the water volume around the filter box 7 in the water tank 1 continuously decreases, and the water volume in the water tank 1 under the water outlet of the circulating water diverter 6 continuously increases, so that the water in the water tank 1 forms flowing water flowing in the direction of the light material conveyor. As the circulating water pump 9 continuously operates, the water in the water tank 1 circulates continuously like this to form circulating water.

[0029] Among them, a partition 11 is arranged in the middle of the circulating water diverter 6 to isolate the water inlet from both sides passing through the conveying pipe 2 and the diversion groove 13, and the water inlet is respectively discharged through the diversion grooves 13 on both sides; the water outlet is provided with evenly distributed diversion plates 12; the diversion plates 12 divert the water inlet of each diversion groove 13 on both sides; ensuring the uniformity of the water velocity and water volume of the sorting water at the water outlet; and because the water inlet is from both sides respectively, the water outlet flow rates of the pumps on both sides can be accurately controlled respectively, so as to accurately control the water flow uniformity of the flowing sorting water in the width direction of the equipment.
