Secondly, according to deep wimble thickener of the present invention, the adjusting material of regulating the pulp density of discharging is to use the solvent or diluent slurry on deep wimble thickener top, promptly, utilization is positioned at the unconcentrated slip in concentrator top, or be concentrated but concentration still is lower than the slip of the pulp density of discharge, or their mixture regulates the concentration of the slip of discharge, includes thinner particle in these slips.Therefore, these can be comprised fine grain solvent or diluent slurry and fully mix by dilution pumps, and then increase concentrated effect through the slip that concentrates; And do not need the dilution water source is set separately, saved the energy, and simple in structure.
Aspect that the present invention adds and advantage part in the following description provide, and part will become obviously from the following description, or recognize by practice of the present invention.
Description of drawings
Above-mentioned and/or other aspects of the present invention and advantage are from obviously and easily understanding becoming the description of embodiment below in conjunction with accompanying drawing, wherein:
Fig. 1 is the schematic diagram of deep wimble thickener according to an embodiment of the invention; With
Fig. 2 is the schematic diagram of deep wimble thickener according to another embodiment of the present invention.
The specific embodiment
Describe embodiments of the invention below in detail, the example of described embodiment is shown in the drawings, and wherein identical from start to finish label is represented components identical.Be used to explain the present invention below by the embodiment that is described with reference to the drawings, described embodiment is exemplary, and can not be interpreted as limitation of the present invention.
Fig. 1 shows deep wimble thickener 100 according to an embodiment of the invention, and as shown in Figure 1, deep wimble thickener 100 comprises main body, agitating device 6, drive unit 4, discharge device and concentration adjusting device.
The main body of deep wimble thickener 100 comprises cylindrical portion 1, cone portion 2 of joining with the bottom of last cylindrical portion 1 and the following cylindrical portion 3 of joining with cone portion 2 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 2 is greater than the bottom diameter.
Agitating device 6 is arranged in the main body, more specifically, as shown in Figure 1, is arranged in the cone portion 2, is used to stir the slip in the main body, thereby slip is concentrated, and agitating device 6 can be the rake frame.
As shown in Figure 1, drive unit 4 can be arranged on the main body top, is used to drive agitating device 6, and particularly, drive unit 4 for example can be drive motors, and drive motors links to each other with the rake frame by drive link 5.
As shown in Figure 1, the discharge device of deep wimble thickener 100 comprises underflow pump 8 and drives the discharge motor 81 that underflow pump 8 rotates.Position near the bottom on the sidewall of following cylindrical portion 3 is formed with discharge gate 3a.The inlet of underflow pump 8 links to each other with discharge gate 3a and outlet links to each other with drainage conduit 14.The entrance and exit side of underflow pump 8 is respectively arranged with valve 15 and 16.
Concentration adjusting device comprises dilution pumps 7 and drives the dilution motor 71 of dilution pumps rotation that the inlet of dilution pumps 7 is connected with last cylindrical portion 1 and outlet links to each other with the inlet of underflow pump 8.More specifically, dilution pumps 7 is connected by the inside of dilution tube 13 with last cylindrical portion 1, can offer through hole 1a on the sidewall of last cylindrical portion 1, and the inlet of dilution pumps 7 links to each other with through hole 1a by dilution tube 13.The entrance and exit side of dilution pumps 7 can be respectively arranged with valve 11 and 12.
Thus, dilution pumps 7 is transported to the porch of underflow pump 8 from the last cylindrical portion 1 interior solvent or diluent slurry that concentration is low, then, solvent or diluent slurry with discharge from cylindrical portion 3 down concentrate after high concentration ground paste underflow pump 8 in, mix after discharge, thereby regulated the concentration of the slip of underflow pump 8 discharges, made pulp density stable.
Need to prove, in the present invention, so-called solvent or diluent slurry, be the high concentration ground paste that concentrates with the process of discharging from the bottom of thickener main body Comparatively speaking, for those having ordinary skill in the art will appreciate that, thickener is exactly the slip that the slip of low concentration is condensed into high concentration, the concentration of the slip on thickener top (for example going up in the cylindrical portion 1) will be lower than the concentration of the slip of discharging the thickener bottom, for example come the last mortar concentration of free factory to be generally 25%, after the process deep wimble thickener concentrates, it is about 75% that the concentration of slip becomes, and therefore, the solvent or diluent slurry is meant the low slip of pulp density that the concentration that concentrates top is discharged in the present invention.In the present invention, solvent or diluent slurry can be the slip that is not concentrated, or has been concentrated but concentration still is lower than the slip of the pulp density of discharge, also can be the water in the slip, perhaps their mixture.
As shown in Figure 1, according to deep wimble thickener of the present invention, drainage conduit 14 is provided with densimeter 9, be used to detect discharging slip concentration and detected concentration signal fed back to concentration adjusting device, for example the signal feedback of densimeter detection is given dilution motor 71, and then the rotating speed of control dilution motor 71, control the solvent or diluent slurry amount that dilution pumps 7 is transported to the inlet of discharge pump 8 according to discharge concentration thus.
And then, on drainage conduit 14, flowmeter can be set, be used to detect the flow that discharging connects, the detection signal of flowmeter also can feed back to discharge motor 81, is used to control the rotating speed of discharge motor 81, thus the discharge capacity of control underflow pump 8.
Fig. 2 shows deep wimble thickener according to another embodiment of the present invention, is with difference embodiment illustrated in fig. 1: in embodiment illustrated in fig. 2, discharge gate is not formed on down on the sidewall of cylindrical portion 3, and is formed in down on the bottom surface of cylindrical portion 3; In addition, dilution tube 13 is not connected with the inside of last cylindrical portion 1 by the through hole that is arranged on the cylindrical portion 1 yet, but dilution tube 13 extends in the cylindrical portion 1 from the top end opening of last cylindrical portion 1.
Other formations of deep cone thickener embodiment illustrated in fig. 2 can be identical with the formation of deep cone thickener shown in Figure 1, repeats no more here.
Although illustrated and described embodiments of the invention, for the ordinary skill in the art, be appreciated that without departing from the principles and spirit of the present invention and can change that scope of the present invention is limited by claims and equivalent thereof to these embodiment.
