The working principle of the sludge concentration dehydrator is as follows: taking two kinds of sludge with different water contents as an example, carrying out 30m cultivation/h under the condition of the same sludge feeding amount; dewatering belt 1.4 materials: non-tab monofilament polyester tape, mesh size longitude: 0.7mm, dimension: 1 mm; the bandwidth is 2m, the effective filtering length is 2515mm, and the running speed of the dewatering filter belt is 1.4, and is adjustable at 5-20 m/min;
when the water content of the sludge is 99.8% (thin sludge), the sludge enters a dewatering filter belt 1.4, a gravity regulator 4 sinks and displaces by 90mm, the dewatering filter belt 1.4 presents a 2-degree lower swing angle, the dewatering filter belt 1.4 presents an inclined triangle, a sludge inlet end is low, a sludge outlet end is high, most of water in the sludge after flocculation under the action of gravity is retained at the lower end (inlet position) of the dewatering filter belt 1.4, and the water directly falls to a water collecting tank 1.7 at the bottom of the dewatering filter belt 1.4 through pores of the dewatering filter belt 1.4 and then is discharged; the sludge (solid) is driven by the friction force of the dewatering filter belt 1.4 to climb upwards until being conveyed to a sludge outlet; therefore, the sludge is dehydrated to about 92 percent, and the effect is better.
When the water content of the sludge is 97% (thick sludge), the sludge enters a dewatering filter belt 1.4, a gravity regulator 4 sinks and displaces 135mm, the dewatering filter belt 1.4 presents a downward swing angle of 3 degrees, the dewatering filter belt 1.4 presents an inclined triangle, a sludge inlet end is low, a sludge outlet end is high, most of water in the sludge after flocculation under the action of gravity is retained at the lower end (inlet position) of the dewatering filter belt 1.4, and the water directly falls to a water collecting tank 1.7 at the bottom of the dewatering filter belt 1.4 through the pores of the dewatering filter belt 1.4 and then is discharged; the sludge (solid) is driven by the friction force of the dewatering filter belt 1.4 to climb upwards until being conveyed to a sludge outlet; therefore, the sludge is dehydrated to about 92 percent, and the effect is better.
The reason for the different downward swing angles of the dewatering belts 1.4 is: the free water of the thin sludge is more, the discharged water is more after the sludge is dehydrated by the dehydration filter belt 1.4, and the gravity of the sludge is reduced; the thick sludge has less relative free water, less discharged water after being dehydrated by the dehydration filter belt 1.4, and less change of the self gravity of the sludge; the method just meets the requirements that the friction coefficient of the thin sludge and the dewatering filter belt is low, the climbing capability is weak, and the downward swinging angle cannot be too large; the friction coefficient of the thick sludge and the dehydration filter belt is 1.4, the climbing capability is high, and the downward swing angle is large. Through the gravity regulator 4, when sludge with different concentrations is treated, the dewatering filter belt 1.4 can be automatically regulated into different climbing angles, so that the dewatering effect of the sludge is better.
The embodiments described above are only a part of the embodiments of the present invention, and not all of them.
