Other formations of stowage unit embodiment illustrated in fig. 2 can be identical with stowage unit shown in Figure 1, repeats no more here.
Describe the deep wimble thickener 1 that uses in the stowage unit of the present invention in detail below with reference to Fig. 2 and Fig. 3.
Shown in Fig. 2 and 3, deep wimble thickener 1 comprises main body, agitating device 25, the drive unit 26 and the circulating system.
The main body of deep wimble thickener 1 comprises cylindrical portion 21, cone portion 22 of joining with the bottom of last cylindrical portion 21 and the following cylindrical portion 23 of joining with cone portion 22 bottoms.Though main body is divided into above-mentioned three parts, yet, need to prove that these three parts can be one.The top end diameter of cone portion 22 is greater than the bottom diameter.
Agitating device 25 is arranged in the main body, more specifically, as shown in Figure 1, is arranged in the cone portion 22, is used to stir the last mortar in the main body, thereby last mortar is concentrated, and agitating device 25 can be the rake frame.
As shown in Figure 3, drive unit 26 can be arranged on the main body top, is used to drive agitating device 25, and particularly, drive unit 26 for example can be drive motors, and drive motors links to each other with the rake frame by driving shaft.
The circulating system of deep wimble thickener 1 will descend the bottom of cylindrical portion 23 to be communicated with the top of following cylinder 3 by pipeline in the main body outside, and will descend the bottom of cylindrical portion 23 to be communicated with by pipeline in the main body outside with last cylindrical portion 21, as shown in Figure 3, the position that last cylindrical portion 21 is communicated with the bottom of following cylindrical portion 23 is between the top of the top of cone portion 22 and last cylindrical portion 21, and best top near cone portion 22, thus, the underflow last mortar of discharging from the following bottom of cylindrical portion 23 can be transported to down in the top of cylindrical portion 23 and/or in the cylindrical portion 21.
When not needing discharge, the underflow last mortar of deep wimble thickener 1 has two kinds of endless form, i.e. cocycle and circulation down, and during cocycle, the tailings of deposition fully mixes near underflow last mortar and the stirring rake frame 25, has the broken effect of encircleing and preventing to press rake; Following circulation time, underflow last mortar are only circulating in the cylindrical portion 23 down, have therefore quickened the sedimentation of the tailings in the cone portion, have realized concentrating fast, have improved thickening efficiency.
As shown in Figure 3, offer slurry outlet 23a in position on the lower sides of following cylindrical portion 23, and down offer circulation overfall hole 23b down on the upper portion side wall of cylindrical portion 23 in position near the top near the bottom.Offer cocycle overfall hole 21a in the position near cone portion 22 tops on the sidewall of last cylindrical portion 21, for example, the distance H between the center of cocycle overfall hole 21a and the top of cone portion 22 can be about 1 meter.And the distance between the top of the center of distance between the bottom of the center of slurry outlet 23a and following cylindrical portion 23 and following circulation overfall hole 23b and following cylindrical portion 23 can all be 0.3 meter.Yet above-mentioned concrete distance only is an example, rather than limitation of the present invention.
The circulating system comprises underflow pump 24, and the inlet of underflow pump 24 links to each other with slurry outlet 23a by pipeline, and circulating line links to each other with cocycle overfall hole 21a with following circulation overfall hole 23b with the cocycle pipeline and the outlet of underflow pump 24 is passed through down respectively.Be respectively arranged with gate valve 28b and 28a on following circulating line and the cocycle pipeline, gate valve 28b and 28a can control and carry out still circulation down of cocycle.
The outlet of underflow pump 24 also links to each other with drainage conduit 29, and drainage conduit 29 is provided with discharge gate valve 28c, and when while closing gate valve 28b and 28a, drainage conduit 29 and discharge gate valve 28c are used for the last mortar after concentrating is discharged in the batch mixing bucket 15.Certainly, the entrance side of underflow pump 24 also can be provided with the gate valve (not shown).
The outlet of underflow pump 24 can also link to each other with accident pool 27 by drainage conduit 29, and the centre is provided with gate valve 28d, thereby when accident occurring, deep wimble thickener 1 interior last mortar can be discharged in the accident pool 27.
According to the present invention, the cocycle of deep cone thickener 1 and following circulation are independent loops, thereby can accelerate thickening efficiency, prevent that the tailings arch camber of inside from harrowing with pressing.
Below with reference to the filling process of Fig. 4 description according to the embodiment of the invention.As shown in Figure 4, filling process according to the embodiment of the invention, first-selection utilizes deep wimble thickener to concentrate the last mortar that comes from the ore dressing plant, with last mortar and the cementitious matter after concentrating, cement for example mixes and stirs into filling slurry, certainly, also the last mortar after concentrating, cementitious matter and Water Quenching Slag can be mixed together and stir into filling slurry, at last the filling slurry for preparing is transported to mine worked-out section.
Alternatively, when mixing and stir last mortar, cementitious matter and Water Quenching Slag, can in it, add water, for example filling slurry can be adjusted to the hydraulic fill slip, high concentration filling slurry, or paste body filling slip so that regulate the concentration of filling slurry.
Under the situation of high concentration and paste body filling slip,, therefore can utilize delivery pump that filling slurry is transported to mine worked-out section because the concentration of filling slurry is higher.
According to the filling process of the embodiment of the invention, owing to adopt deep wimble thickener that last mortar is concentrated, therefore, do not need the last mortar after concentrating utilized again and press the machine of quenching to carry out dehydrating operations, thickening efficiency improves, and equipment is simple, and cost is low.And then, by circulation up and down is set, can further improve thickening efficiency on deep wimble thickener, improve concentrated effect.
