The inclined tube purifier is made up of frp honeycomb inclined tube and bracing or strutting arrangement thereof.The inclined tube purifier as shown in figures 1 and 3 in this example.It mainly comprises frp honeycomb inclined tube (12), the crossbeam (9) of support glass steel honeycomb inclined-tube (12), the rack (10) and the wire netting (11) of reinforcing frp honeycomb inclined tube (12).

The structure of fluidization inverted-loop tube slurry-discharging equipment such as Fig. 4 are to shown in Figure 6.

The structure of slurry-discharging equipment as shown in Figure 4.It mainly comprises center discharge pipe (16), inverted U-shaped discharge pipe (25), bottom discharge pipe (18), hose valve (19), fluidised form bag (24).Wherein, manage (16) and be contained in top, fluidised form bag (24) center, it and inverted U-shaped discharge pipe (25) are the main pipe of using of normal discharge pipe together; Pipe (18) is contained in fluidised form bag (24) central lower, is the bottom-dump discharge pipe, mainly is as emptying usefulness, also can be used as the standby pipes of normal discharge pipe.

Fluidization equipment is to regulate underflow density or plasma discharge just use at need at needs.It comprises umbrella shape fluidization equipment and annular fluidization equipment.The umbrella shape fluidization equipment comprises pressure water supply pipe (12-a), umbrella hat (13), pressurized tank (14), nozzle (15-a), blow-down pipe (22-a).Nozzle quantity is determined according to concentrated phase layer concentration being become requirement transportation concentration time institute amount of water.Nozzle in this example (15-a) has 8, is welded on pressurized tank (14) circumference, as shown in Figure 4 and Figure 5 by pseudo-tilted radiation shape is uniform.The annular fluidization equipment comprises pressure water supply pipe (12-b), annular pressure pipe (23), nozzle (15-b), blow-down pipe (22-b).Nozzle (15-b) has 8, is welded on the annular pressure pipe (23) its welding position and angle such as Fig. 4 and shown in Figure 6, uniform 4 of inner ring, injection direction points to center discharge pipe (16), uniform 4 of outer ring, and injection direction points to fluidised form bag (24) upper inside wall position.

Fluidization inverted-loop tube slurry-discharging equipment is welding and bolt fastening structure, and it is fixed, installation method is: the umbrella hat of umbrella shape fluidization equipment (13) is welded on the column upper end of bracing frame (17); The annular pressure pipe (23) of annular fluidization equipment is fixed on the column bottom of bracing frame (17) with angle steel clip (21) and bolt, nut; Column is made by steel pipe, and it is enclosed within on the backstay (20); On backstay (20) is welded at the bottom of the awl of fluidised form bag (24).

The utility model ore pulp concentrates, discharge process can be summarized as follows: low concentration slurry (thin pulp) enters for slurry pipe (6) by the center, after joining slurry pipe (7), buffer (8) deceleration, break-in, at first carry out Separation of Solid and Liquid, it is the higher slurry of solid content, dependence is from resedimentation, to dark cone (1-b); Contain the less liquid of particulate and rise,, become supernatant, come together in overflow launder (1-e), discharge outside the storehouse by overflow pipe through the further post precipitation of inclined tube purifier (2).

After the solid-liquid separation on ore pulp, promptly begin to concentrate, discharge.After the higher concentration slurry is reduced to dark cone (1-b), it is close to carry out three axial compressions, forms the high concentration concentrated phase layer (underflow) of a densification at this, and this underflow glides swimmingly along awl base slope angle, and be pressed into center discharge pipe (16), discharge smoothly through inverted-loop tube (25).

During in the ordinary course of things with normal operation, do not need to use fluidization equipment, just when needs are regulated underflow density and eliminated the plasma discharge obstacle, just use, and service time is very short, gets final product in about 10～20 minutes.

Utilize above-mentioned ore pulp to concentrate the storehouse, carried out iron raw ore slurry, iron ore concentrate slurry, three kinds of slurries of uranium raw ore slurry industry concentration test, experimental condition, result are as shown in the table.

The utility model has following advantage and good effect compared to existing technology:

1. the saving energy. Should concentrate the storehouse did not need power in the ordinary course of things, and no power consumption is just regulated underflow density and underflow discharge at need at needs, just need short time startup fluidization equipment.

2. saving material. When concentrating general particle slurry, do not need to use flocculant, only when concentrating special Fine Particle Slurry, just need to use a small amount of flocculant.

3. floor space is little, disposal ability is big. The big several times of the more traditional concentrator of unit are disposal ability.

4. plasma discharge is smooth. By the inverted-loop tube slurry-discharging equipment, generally can both successfully discharge underflow, even discharging is obstructed, utilize fluidization equipment, just can in time discharge obstacle.

5. maneuverability. Should concentrate the storehouse have certain storage slurry ability, and when operation or rear operation generation short duration failure, the unlikely system that affects stops production, and has kept the continuity of localized production before concentrating the storehouse.
