Description

Technical Field

[0001] The utility model belongs to the technical field of material flocculation and sedimentation, and particularly relates to a self-dilution and flocculant mixing material distribution device. Background Art

[0002] At present, the most common practice for the cleaned slurry is to recycle the metal ions in the slurry. During the recycling process, the slurry needs to be concentrated, flocculated and settled. Specifically, during the flocculation process, the supernatant in the concentration tank needs to be used as a self-diluting liquid, and the self-diluting liquid needs to be mixed with the slurry and the flocculant before the flocculation operation is performed.

[0003] The more common practice at present is to independently pump out the supernatant in the concentration tank and use it as the self-diluting liquid in the flocculation process. The slurry, flocculant and self-diluting liquid are then mixed and concentrated again after flocculation and sedimentation.

[0004] First, this method requires independent pumping of the supernatant in the concentration tank. Second, during the flocculation process, after the slurry, flocculant, and self-dilution liquid are pumped to the concentration tank, it is difficult to quickly and fully mix the materials and quickly flocculate and settle them in the large-volume concentration tank.

[0005] Therefore. In the actual working process, the flocculation effect is not high. It is reflected in that, in the flocculation process, when the flocculant is added to the liquid system of the slurry and the self-diluting liquid, the flocculation and sedimentation speed of the material is too slow because the flocculant is not fully mixed in the liquid system, and the flocculation and sedimentation effect is poor. Therefore, after the flocculated material system is concentrated again, not only the concentration time is long, but also the concentration effect is not ideal due to insufficient flocculation. Therefore, the material processing efficiency is not high. Utility Model Content

[0019] The intermediate tube is connected to the material cloth guide cone, and the material guide plate is located above the material cloth guide cone.

[0020] Preferably, the jet tube mechanism comprises a feed tube portion, and the feed tube portion is integrally formed with a self-jet tube portion with a reduced tube diameter;

[0021] The self-jet tube portion is integrally formed with a mixing tube portion, and the mixing tube portion is integrally formed with a bent discharge tube portion, and the bent discharge tube portion is connected to the inner circulation mixing cone.

[0022] Preferably, the self-jet tube portion is connected to a flocculant feeding pipe and a self-dilution water inlet pipe.

[0024] The mixing structure comprises mesh plates fixedly connected to both sides of the lumen of the mixing tube, and a plurality of spiral mixing sheets are fixedly connected between the mesh plates.

[0025] The utility model has the following beneficial effects:

[0026] 1. Through the internal circulation mixing cone, external stabilizing cylinder, guide plate, distribution guide cone and other structures, during the working process, after the mixed liquid such as slurry and reagents is sprayed out of the jet tube mechanism, it is initially fully mixed by the above-mentioned mixing structure, which first improves the efficiency of the use of the reagent. Secondly, after mixing, the material system first enters the internal circulation mixing cone. Under the action of gravity vortex, the initially flocculated material flows to the outside and bottom, and enters the external stabilizing cylinder along the guide flow hole. Through the guide plate, the material is diffused to the periphery of the concentrator under the action of the guide plate and the distribution guide cone. This method can not only effectively mix the reagents and make the materials flocculate quickly, but also accelerate the sedimentation rate, greatly improving the processing capacity of the concentrator.

[0027] 2. Through the jet tube mechanism, specifically, a feed pipe part and a self-jet pipe part with a reduced diameter that is integrally formed with the feed pipe part (because of the reduced diameter, the slurry flow rate increases at this time, and after the flow rate increases, a negative pressure area is formed). During operation, the above-mentioned self-jet pipe part is connected with a flocculant feeding pipe and a self-dilution water inlet pipe. The self-dilution water inlet pipe is connected to the supernatant of the concentration tank through a connecting pipe. Because the negative pressure in the self-jet pipe part increases, the supernatant of the concentration tank is automatically sucked into the self-jet pipe part and mixed with the slurry to dilute the slurry. At the same time, the flocculant feeding pipe is connected to the flocculant feeding pipe. Similarly, under negative pressure, the flocculant is automatically sucked. In this way, the materials and reagents in the flocculation process are automatically finely divided and mixed in a simple way that is energy-saving, environmentally friendly, and easy to operate.

[0038] Example 1

[0039] like Figure 1-5 As shown, a self-dilution and flocculant mixing and distributing device includes a jet tube mechanism, and the jet tube mechanism is used for negative pressure absorption of self-dilution solution. Specifically, the jet tube mechanism includes a feed pipe part 1 (according to the existing method, the slurry is fed from the feed pipe part 1), and the feed pipe part 1 is integrally formed with a self-jet pipe part 2 with a reduced pipe diameter (because the pipe diameter is reduced, the slurry flow rate increases at this time, and after the flow rate increases, a negative pressure area is formed). The above-mentioned self-jet pipe part 2 is connected with a flocculant feeding pipe 22 and a self-dilution water inlet pipe 21. The self-dilution water inlet pipe 21 is connected to the supernatant of the concentration tank through a connecting pipe. Because the negative pressure in the self-jet pipe part 2 increases, the supernatant of the concentration tank is automatically sucked into the self-jet pipe part 2 and mixed with the slurry to dilute the slurry.

[0040] At the same time, the flocculant feeding pipe 22 is connected to the flocculant supply pipe, and the flocculant is automatically sucked under negative pressure. In this way, the materials and reagents in the flocculation process are automatically finely mixed in an energy-saving, environmentally friendly, and simple way.

[0041] In order to achieve preliminary mixing of the material and liquid, the self-jet tube 2 is integrally formed with a mixing tube 3, specifically, a mixing structure is fixedly connected in the mixing tube 3; the mixing structure includes mesh plates 31 (the mesh plates 31 have multiple through-hole structures) fixedly connected to both sides of the tube cavity of the mixing tube 3, and a plurality of spiral mixing sheets 32 are fixedly connected between the mesh plates 31. When the ore pulp, dilute solution, and flocculant enter the mixing tube 3, preliminary mixing is performed under the guidance of the spiral mixing sheets 32 of the spiral structure, so that the material system can be preliminarily mixed in a simple, convenient and efficient manner.

[0042] The mixing pipe section 3 is integrally formed with a bent discharge pipe section, and the bent discharge pipe section is connected to the following internal circulation mixing cone.

[0043] Example 2

[0044] like Figure 1-5 As shown, based on the structure of Example 1, the self-dilution and flocculant mixing distribution device of this embodiment further includes a distribution mechanism, through which the material system is fully mixed again. Specifically, the distribution mechanism includes an outer stabilizing tube 5 located on the outside, and an inner circulation mixing cone 4 (shaped as follows: the inner circulation mixing cone 4 includes a conical cylinder, and the conical cylinder is integrally formed with a circular bottom) is assembled and connected inside the outer stabilizing tube 5, and the discharge end of the jet tube mechanism is connected to the inner circulation mixing cone 4 (the above-mentioned curved discharge pipe is connected to the inner circulation mixing cone 4 described below).

[0045] The material distribution mechanism also includes an intermediate tube 7 fixedly connected to the middle part of the inner circulation mixing cone 4 (the intermediate tube 7 is fixedly connected to the center part of the circular bottom); the material distribution mechanism also includes a flow guide mechanism coordinated with the inner circulation mixing cone 4, and the inner circulation mixing cone 4 is provided with a plurality of flow guide holes 41 (the flow guide holes 41 are provided on the circular bottom and the conical cylinder). The intermediate tube 7 is fixedly connected to the center part of the inner circulation mixing cone 4. During the working process, the material system is separated and diverted to the lower part through the flow guide mechanism, and the flocculation effect and mixing effect of the material are further improved during the diversion and discharge process.

[0046] Specifically, the flow guiding mechanism includes a plurality of guide plates 8, one side of the guide plates 8 is welded to the side wall of the middle tube 7, and the other side of the guide plates 8 is welded to the bottom of the circular bottom. The guide plates 8 are located between adjacent flow guiding holes 41. During operation, the material discharged from the flow guiding holes 41 is guided along the guide plates 8.

[0047] The above-mentioned flow guiding mechanism also includes a cloth flow guiding cone 6 (the top of the cloth flow guiding cone 6 has a hole structure 61 connected to the intermediate tube 7), and the intermediate tube 7 is fixedly connected to the cloth flow guiding cone 6. The above-mentioned intermediate tube 7 is connected to the cloth flow guiding cone 6, and the material guiding plate 8 is located above the cloth flow guiding cone 6.

[0048] During operation, after the mixed liquid of slurry, reagents, etc. is ejected from the jet tube mechanism, it is initially and fully mixed by the above-mentioned mixing structure, which firstly improves the use efficiency of the reagents. Secondly, after mixing, the material system first enters the inner circulation mixing cone 4. Under the action of gravity vortex, the initially flocculated material flows to the outside and the bottom, and enters the external steady flow cylinder along the guide hole 41. Through the guide plate 8, the material is diffused to the periphery of the concentration tank under the action of the guide plate 8 and the material distribution guide cone 6. This method can not only effectively mix the reagents and make the materials flocculate quickly, but also accelerate the sedimentation rate, greatly improving the processing capacity of the concentrator.

[0049] Of course, the above description is not a limitation of the present invention, and the present invention is not limited to the above examples. Changes, modifications, additions or substitutions made by technicians in this technical field within the essential scope of the present invention should also fall within the protection scope of the present invention.
