Description

Technical Field

[0001] The invention belongs to the technical field of mine wastewater treatment, and in particular relates to a wastewater treatment device for a seaside sand ore dressing plant. Background Art

[0002] A sand concentrator is a facility specially used for handling and processing sand ore. Its purpose is to separate useful mineral components from the sand ore. Its main operations include washing, screening and grading. Sand ore washing is the process of separating useful minerals and removing impurities from the original sand ore. However, in this process, fine particles, soil and other suspended matter in the ore are usually brought into the wastewater to form muddy water. However, the formed muddy water does not meet environmental protection standards and cannot be discharged directly. It needs to undergo a series of treatments to remove suspended matter, salt and other pollutants to ensure emission standards.

[0003] When treating wastewater, the existing wastewater treatment device of the sand dressing plant usually collects the wastewater in a collection pool first, performs preliminary treatment by adding some flocculants to separate water from sediment, blends the separated water to meet the discharge standard and discharges it, and dehydrates the remaining sediment through a filter belt and recovers it when it is dehydrated into solid. Although the wastewater can be treated, the treatment process is inefficient and cannot treat a large amount of wastewater within a limited time and ensure that the treatment is clean and thorough. Summary of the invention

[0004] The technical problem to be solved by the present invention is to overcome the disadvantages of the above-mentioned prior art and provide a wastewater treatment device for a seaside sand beneficiation plant.

[0005] The technical solution adopted to solve the above technical problems is: a wastewater treatment device for a seaside sand beneficiation plant, comprising a bottom plate, a wastewater pool is fixedly connected to one side of the top front end of the bottom plate, a wastewater separation mechanism is fixedly connected to the top of the bottom plate and close to the rear end of the wastewater pool, and a stirring mechanism is installed in the wastewater separation mechanism;

At the same time, most of the wastewater is muddy water, and the fine particles in the muddy water will form larger floccules, which are convenient for settling at the bottom of the separation tank. The separated clean water flows into the outside of the separation cover through multiple through holes. Since the clean water also contains small particles of mud and sand, when passing through the annular inclined tube plate, it will flow downward along the inner wall of the inclined tube due to its own weight, and finally settle at the bottom of the separation tank, which has a secondary separation effect and improves the filtering effect of muddy water.

The mud and water are finally discharged through the corresponding water outlet pipe. The mud discharge plate can guide the mud and water discharged by the mud discharge mechanism, making it convenient for the mud and water separation mechanism to separate them.

A plurality of springs 1006 are fixedly connected to the bottom of the mounting plate 1005. The pressing plate 100 The top of 4 is fixedly connected with the bottom of multiple springs 1006. When the mud cake flows to the bottom of the pressing plate 1004 through the first filter belt 907 and the mud discharge plate 707, the two cylinders 1002 are started. The two cylinders 1002 squeeze the connecting block 1003 connected thereto through the piston, and then push the pressing plate 1004, so that the pressing plate 1004 squeezes the mud cake on the first filter belt 907, and further separates the mud and water in the mud cake. At the same time, the multiple springs 1006 at the top center of the pressing plate 1004 provide elastic force, so that multiple points of the pressing plate 1004 squeeze the mud cake, which greatly improves the dehydration effect of the mud cake.

[0046] like Figure 1-Figure 6 As shown, a cleaning mechanism 11 is installed inside the mud and water treatment component 7, and the cleaning mechanism 11 includes a first water pipe 1101 fixedly connected to one side of the top of the center of the mud and water treatment frame 701, and a second water pipe 1102 is fixedly connected to the other side of the bottom of the center of the mud and water treatment frame 701. The bottom ends of the outer walls of the first water pipe 1101 and the second water pipe 1102 are fixedly connected to a plurality of nozzles 1103, and the top of the bottom plate 1 and the rear end position near the mud and water treatment frame 701 are fixedly connected to a fourth water pump 1104, a second water pumping pipe 1105 is fixedly connected between the fourth water pump 1104 and the clean water tank 5, and a connecting pipe 1106 is fixedly connected between the rear ends of the first water pipe 1101 and the second water pipe 1102. Take over 1107, a second drain pipe 1106 is fixedly connected between the fourth water pump 1104 and the connecting pipe 1107. When the mud cake is dried and discharged, start the fourth water pump 1104, and the fourth water pump 1104 draws clean water in the clean water tank 5 through the second pumping pipe 1105, and the clean water flows to the connecting pipe 1107 through the second drain pipe 1106, and then flows to the first water pipe 1101 and the second water pipe 1102 respectively through the connecting pipe 1107, and then the first filter belt 907 and the second filter belt 908 are cleaned respectively through the corresponding multiple nozzles 1103, so that the first filter belt 907 and the second filter belt 908 can be reused, thereby improving the dehydration and filtering effects of the mud cake.

[0047] like Figure 1-Figure 6As shown, a discharge mechanism 12 is installed at the top of the bottom plate 1 and near the front end of the mud and water treatment component 7, and the discharge mechanism 12 includes a fixed bar 1201 fixedly connected to the center side of the mud and water treatment frame 701, and a plurality of evenly distributed cutting plates 1202 are fixedly connected to the outer wall of the fixed bar 1201, and the plurality of cutting plates 1202 are close to the bottom of one side of the first filter belt 907, and a feeding rack 1203 is fixedly connected to the top of the bottom plate 1 and near the front end of the mud and water treatment frame 701. The feeding rack 1203 penetrates the center side of the mud and water treatment frame 701, and a feeding belt 1204 is installed on the feeding rack 1203. After the mud cake is dried, when it falls onto the plurality of cutting plates 1202 through one side of the second filter belt 908, the plurality of cutting plates 1202 cut the mud cake due to its own gravity, and finally it falls onto the feeding belt 1204, and is transported outward by the feeding belt 1204.

[0048] The working principle of this embodiment is as follows: the wastewater pool 2 collects wastewater from the mine washing. When the wastewater in the wastewater pool 2 is processed, the first water pump 601 is started, and the first water pump 601 extracts the wastewater in the wastewater pool 2 through the first mud pumping pipe 602, and then discharges it into the separation tank 302 through the first mud discharge pipe 603, and first pumps it into the separation cover 303, and at the same time, adds flocculant, and starts the first motor 406. The first motor 406 drives the stirring shaft 403 to rotate through the output shaft, and then drives the first stirring paddle 404 and the second stirring paddle 405 to rotate, so as to remove the suspended matter in the wastewater, and at the same time, the waste Most of the water is muddy water, and the fine particles in the muddy water will form larger flocs and settle at the bottom of the separation tank 302. The separated clean water flows into the outside of the separation cover 303 through multiple through holes 304. Since the clean water also contains small particles of mud and sand, when passing through the annular inclined tube plate 305, it will flow downward along the inner wall of the inclined tube due to its own weight, and finally settle at the bottom of the separation tank 302. The second water pump 604 is started, and the second water pump 604 extracts the clean water in the upper part of the separation tank 302 through the first pumping pipe 605, and then discharges it into the clean water tank 5 through the first drain pipe 606;

[0049] When the muddy water at the bottom of the separation tank 302 is processed, the third water pump 805 is started, and the third water pump 805 extracts the muddy water at the bottom of the separation tank 302 through the second mud extraction pipe 806, and then flows to the second mud discharge pipe 801 through the third mud discharge pipe 807, and then flows to the first filter belt 907 through multiple mud discharge pipes 802 and corresponding mud discharge racks 804;

[0050] At the same time, the second motor 909, the third motor 910, the fourth motor 911 and the fifth motor 914 are started to respectively drive the first guide roller 901, the feeding roller 902 and the second guide roller 903 connected thereto to rotate. The output shaft of the fifth motor 914 rotates to drive the first squeezing roller 904 connected thereto to rotate, and at the same time drives the connected gear 912 to rotate. The remaining gears 912 mesh with each other and rotate, so that the two first squeezing rollers 904 and the two second squeezing rollers 905 rotate in opposite directions, and cooperate with the remaining first guide rollers 901 and second guide rollers 903 to rotate. The rollers 903 drive the first filter belt 907 and the second filter belt 908 to drive. The muddy water is slowly dehydrated into mud cakes through the first filter belt 907, passes through multiple mud separation racks 709 and is layered, and then passes through the mud discharge plate 707. When it flows to the bottom of the pressing plate 1004, the two cylinders 1002 are started. The two cylinders 1002 squeeze the connecting blocks 1003 connected thereto through the pistons, and then push the pressing plate 1004, so that the pressing plate 1004 squeezes the mud cake on the first filter belt 907, and further separates the muddy water in the mud cake.

[0051] After being dehydrated again, it flows into the space between the first filter belt 907 and the second filter belt 908, and is squeezed and separated into muddy water by two second squeezing rollers 905 and the first squeezing roller 904 adjacent thereto. The muddy water is discharged outward through a plurality of drainage holes 906. After the mud cake is finally dehydrated, it passes through one side of the second filter belt 908 and falls onto a plurality of cutting plates 1202. Due to the weight of the mud cake itself, the plurality of cutting plates 1202 cut it and finally falls onto the feeding belt 1204, where it is transported outward by the feeding belt 1204.

[0052] After the mud cake is dried and discharged, the fourth water pump 1104 is started, and the fourth water pump 1104 extracts clean water in the clean water tank 5 through the second water pumping pipe 1105, and the clean water flows to the connecting pipe 1107 through the second drainage pipe 1106, and then flows to the first water pipe 1101 and the second water pipe 1102 respectively through the connecting pipe 1107, and then the first filter belt 907 and the second filter belt 908 are cleaned respectively through the corresponding multiple nozzles 1103;

[0053] The muddy water filtered by the first filter belt 907 and the second filter belt 908 after dehydrating the mud cake, and the muddy water cleaned by the first filter belt 907 and the second filter belt 908 are collected by the first drainage frame 703 and the second drainage frame 704 respectively, and finally discharged through the corresponding outlet pipe 705.

[0054] The above description is only a preferred embodiment of the present invention and is not intended to limit the protection scope of the present invention.
