Abstract

The utility model provides an improved dehydration machine, the settling speed of particles is speeded up by adopting a high weir enclosing plate machine for concentrating, the settling effective area is expanded, and the critical particle diameter is reduced. The device not only improves the concentrating efficiency, but also obtains clear liquid which is consistent with the requirement of discharge standard. The utility model has the advantages of few pollution, high effectiveness and simple structure, and floater can also be recovered simultaneously. Because the utility model only adds the enclosing plate on the traditional machine for concentrating, the rake bracket reinforcing is easy to be realized.

Description

High weir enclosing plate machine for concentrating
The utility model relates to a kind of improved dewatering machine, particularly a kind of high-weir type coaming plate thickener.
Ore dressing plant, the overwhelming majority of power plant adopt the wet type sorting operations at present, and therefore, dewatering operation just becomes a necessary less important work.Because the thickening efficiency of traditional thickener is low, the particle velocity in the slurry is slow, and underflow density is lower, minimumly reaches 8%.Be not lower than 3/1000ths discharge standard requirement so the solid content of the clarified solution that flows out in the overflow launder reaches, after this clarified solution discharging, can pollute to surrounding environment.If clarified solution recycles, wherein the pearl that floats of Xuan Fuing enters in the pump, and pump will be damaged.Emit with clarified solution if float pearl, also can cause loss economically.
The purpose of this utility model just provides a kind of improved dewatering machine, adopts high-weir type coaming plate thickener to add the sinking speed of fast particle, enlarges the sedimentation effective area, dwindles critical particle diameter.This device has not only improved thickening efficiency, and can obtain the clarified solution that allow compliance with emission standards requires, to reduce the pollution to environment.Can also reclaim simultaneously and float pearl, to increase economic efficiency.
The purpose of this utility model is achieved in that before the annular overflow trough of traditional thickener, and a coaming plate is set, and clarified solution is flow to the overflow launder from coaming plate bottom overflow area.Thereby the flow regime of slurry in the change concentration basin reaches the purpose that improves thickening efficiency.
Because the utility model only needs to add a coaming plate before the overflow launder of traditional thickener, just can reach the purpose that improves thickening efficiency, so it is simple in structure, realize easily.
Below in conjunction with accompanying drawing the utility model is described in further detail.
Fig. 1 is the utility model concrete structure schematic diagram.
Fig. 2 is the partial enlarged drawing of Fig. 1.
Fig. 3 is a particle flow graph in traditional thickener slurry.
Fig. 4 is a particle flow graph in the utility model slurry.
According to Fig. 1 and Fig. 2, at the preceding coaming plate that is provided with of the overflow launder (1) of thickener, this coaming plate is to be surrounded by the watertight fixed dam of annular enclosed shape (6).Employing is stuck in the geometrical clamp on the overflow launder (1) or is embedded in steel bracket on the overflow launder, it is preceding that fixed dam (6) is fixed on overflow launder (1), the side that makes fixed dam (6) is apart from overflow launder (1) edge 200~300mm, its upper surface should exceed more than the concentration basin spillwag chute 100mm, and the lower surface is far from bottom surface, pond 200~500mm.Water-tight materials such as the available plank of fixed dam (6), steel plate, plastic plate are made.The feeder trough (5) of ore pulp on truss that concentrates when need feeds the concentration basin center when being subjected to barrel (4), ore pulp just radially toward around flow.In traditional thickener, the particle flux of slurry is to as shown in Figure 3, because clarified solution is to flow to the overflow launder (1) from concentration basin top overflow area, so particle also has the branch speed that upwards flows except that because of from resedimentation, influences the sinking speed of particle, strengthen critical particle diameter, reduced thickening efficiency.In the high-weir type coaming plate thickener of the present utility model, the particle flux of slurry is to as shown in Figure 4, the particle of slurry is except that producing the downward sinking speed because of deadweight, be that bottom overflow area from fixed dam (6) flows to the overflow launder (1) also because of clarified solution, so branch speed that particle flows downward in addition, so accelerated the sinking speed of particle, enlarged the sedimentation effective area, dwindled critical particle diameter.Therefore, the utility model has not only improved thickening efficiency, is lower than 3/1000ths discharge standard but also make the clarified solution of discharge reach solid content, meanwhile, floats pearl and can also remain in the fixed dam (6) and reclaim.Like this, can not only reduce infringement, and reclaim and to float pearl and can also increase economic efficiency pump.Because thickening efficiency improves, the discharge capacity of discharge port (8) is big, so rake frame (2), (7) that transmission beam (3) drives should suitably reinforce, to improve the load intensity of rake frame (2), (7), satisfies the big requirement of the utility model treating capacity.

Claims (3)

1, a kind of high-weir type coaming plate thickener that formed by barrel [4], feeder trough [5], discharge port [8] by overflow launder [1], rake frame [2], [7], transmission beam [3], center is characterized in that having the coaming plate that is surrounded by the fixed dam [6] that is fixed on the overflow launder [1].
2, high-weir type coaming plate thickener according to claim 1 is characterized in that fixed dam (6) adopts the steel bracket that is stuck in the geometrical clamp on the overflow launder (1) or is embedded on the overflow launder (1) to fix.
3,, it is characterized in that fixed dam (6) made by plank or water-tight material such as steel plate or plastics according to claim 1 and 2 described high-weir type coaming plate thickeners.
