Description

Technical Field

[0001] The utility model relates to the technical field of mining sewage treatment, in particular to a flocculant dosing mechanism of a mining deep cone thickener. Background Art

[0002] Mining deep cone thickeners are generally used in mine wastewater treatment. The overall shape is a vertical barrel cone with a slender pool body. Flocculants are added in the process of concentrating wastewater to accelerate material sedimentation and overflow water clarification. At the same time, mining deep cone thickeners can also be used for the concentration of other slurries with fine particles and low density and wastewater treatment.

[0003] Traditional deep cone thickeners for mining are relatively high, generally reaching a height of more than 4 meters. Taking the NZSG deep cone thickener for mining as an example, a dosing port for flocculant is opened on the top, and the transmission shaft passes through the dosing trough. The flocculant is input through the dosing port and enters the deep cone thickener for mining along the dosing trough. When adding the flocculant, the staff needs to climb to the top of the deep cone thickener for mining, which is very troublesome. At the same time, the flocculant is prone to accumulation when adding the flocculant, which affects the dispersion degree and thus affects the reaction speed. Further improvements can be made.

[0004] Currently, no effective solution has been proposed for the problems in the related technologies. Utility Model Content

With reference to these contents, ordinary technicians in the field should be able to understand other possible implementation methods and advantages of the present invention. The components in the figures are not drawn to scale, and similar component symbols are generally used to represent similar components.

[0028] According to an embodiment of the utility model, a flocculant dosing mechanism for a deep cone thickener for mining is provided.

[0029] The present invention is now further described in conjunction with the accompanying drawings and specific implementation methods. Figure 1-4As shown, a flocculant dosing mechanism of a deep cone thickener for mining according to an embodiment of the utility model comprises a deep cone thickener body 1 for mining and a transmission shaft 3. The transmission shaft 3 is installed inside the deep cone thickener body 1 for mining, and a feeding trough 2 is fixedly installed on the top of the deep cone thickener body 1 for mining on the outside of the transmission shaft 3. It is a common structure in the art and will not be described in detail here. A first conveying cylinder 4 is connected to the surface of one side of the feeding trough 2, and the other end of the first conveying cylinder 4 extends to the outside of the deep cone thickener body 1 for mining and is fixedly installed with a first drive motor 6, and a first auger 5 is installed inside the first conveying cylinder 4. The first auger 5, a first conveying cylinder 4 is extended from one end, an output end of a first driving motor 6 is fixedly connected to a mounting end of a first auger 5, a top surface of the other end of the first conveying cylinder 4 is connected through a feed hopper 7, a second conveying cylinder 9 is fixedly mounted on one side of the main body 1 of the mining deep cone thickener through a mounting frame 11, a second auger 10 is installed inside the second conveying cylinder 9, and a second driving motor 13 is fixedly installed on the bottom surface of the second conveying cylinder 9, an output end of the second driving motor 13 is fixedly connected to a mounting end of the second auger 10, the other end of the second auger 10 is rotatably connected to the inner top surface of the second conveying cylinder 9, and a feeding hopper is connected through a surface on one side of the bottom of the second conveying cylinder 9 12, and the top side surface of the second conveying cylinder 9 is connected with the feed hopper 7 through the feed pipe 8, and the outer surface of the transmission shaft 3 is located below the feed trough 2 and is fixedly sleeved with a spreading plate 14. When adding flocculant to the inside of the deep cone thickener body 1 for mining, the flocculant can be put into the feed hopper 12, and the flocculant enters the second conveying cylinder 9 along the feed hopper 12. The second drive motor 13 drives the second auger 10 to rotate, thereby driving the flocculant entering the second conveying cylinder 9 to move upward, and enter the feed hopper 7 through the feed pipe 8, and enter the first conveying cylinder 4. The first drive motor 6 is started to drive the first auger 5 to rotate. The flocculant is driven into the feeding trough 2 and then added to the main body 1 of the deep cone thickener for mining. The staff can complete the addition of the flocculant on the ground, eliminating the trouble of climbing to the top surface of the deep cone thickener main body 1 for adding medicine, which significantly improves the convenience of adding medicine and improves the work efficiency. At the same time, the rotation of the transmission shaft 3 drives the spreading plate 14 to rotate, and the flocculant flowing out of the first conveying cylinder 4 falls to the top surface of the spreading plate 14. Under the rotation action of the spreading plate 14, it is dispersed and scattered into the interior of the deep cone thickener main body 1 for mining, which improves the uniformity of adding medicine, thereby accelerating the reaction speed and further improving the efficiency of adding medicine.

[0030] In one embodiment, the bottom surface of the spreading tray 14 is integrally connected with a sleeve 15, and both ends of the sleeve 15 are integrally connected with ear plates 16, and the ear plates 16 are fixedly connected by fixing bolts 17. The fixing bolts 17 penetrate the ear plates 16 and are fixedly connected to the ear plates 16 by nuts, which is a common fixing form. A fixing hole 18 is opened at the center of the spreading tray 14, and rubber pads 19 are fixedly bonded to the fixing hole 18 and the inner wall of the sleeve 15.

[0031] In one embodiment, the inner diameter of the fixing hole 18 is the same as the inner diameter of the sleeve 15, and the sleeve 15 is coaxially arranged with the fixing hole 18, wherein the inner diameter of the sleeve 15 is larger than the outer diameter of the transmission shaft 3, and the outer diameter of the transmission shaft 3 is larger than the inner diameter of the rubber pad 19. When the sleeve 15 is fixed, the rubber pad 19 is squeezed and deformed, resulting in large friction, thereby preventing the spreading plate 14 and the sleeve 15 from moving and improving the stability of the installation.

[0032] In one embodiment, the first conveying cylinder 4 is arranged horizontally, and the second conveying cylinder 9 is arranged vertically, so as to facilitate the lifting and feeding of the flocculant.

[0034] Working principle:

[0035] When adding flocculant to the inside of the deep cone thickener body 1 for mining, the flocculant can be put into the feeding hopper 12, and the flocculant enters the second conveying cylinder 9 along the feeding hopper 12. The second drive motor 13 drives the second auger 10 to rotate, thereby driving the flocculant entering the second conveying cylinder 9 to move upward, and enter the feed hopper 7 through the feed pipe 8, and enter the first conveying cylinder 4. The first drive motor 6 is started, driving the first auger 5 to rotate, driving the flocculant to enter the feeding trough 2, and thus adding it to the deep cone thickener body 1 for mining. In the process, the staff can complete the addition of flocculant on the ground, eliminating the trouble of climbing to the top surface of the deep cone thickener body 1 for adding medicine, which significantly improves the convenience of adding medicine and improves work efficiency. At the same time, the rotation of the transmission shaft 3 drives the spreading plate 14 to rotate, and the flocculant flowing out of the first conveying cylinder 4 falls to the top surface of the spreading plate 14, and is dispersed and scattered into the interior of the deep cone thickener body 1 under the rotation of the spreading plate 14, which improves the uniformity of adding medicine, thereby accelerating the reaction speed and further improving the efficiency of adding medicine.
