Description

TECHNICAL FIELD

[0001] The utility model belongs to the technical field of mineral processing wastewater recycling, especially relates to a mineral processing wastewater recycling backwashable large-flux security filter formula. BACKGROUND

[0002] Mineral processing wastewater is the general term of mineral processing process drainage, tailings pond and mine drainage. The wastewater has large water volume, high suspended solids content and many harmful substances with low concentration. The water consumption for processing one ton of ore is 5-10 tons. The wastewater quality varies with the type of mineral processing, mainly containing heavy metal ions (copper, zinc, lead, nickel, iron, barium, arsenic, cadmium, etc.) and mineral processing reagents (xanthate, black medicine, cyanide, pine root oil, cresol, copper sulfate, heavy metal salts, sodium sulfate, sulfuric acid, lime, etc.). The untreated discharge or loss of mineral processing wastewater will seriously pollute the environment and endanger the health of aquatic products, plants and human bodies. Generally, large-volume tailings water (suspended ore process drainage and tailings slurry) sedimentation-storage ponds are set up, which are often built on landforms such as valleys, slopes and riverbanks and surrounded by dams. The suspended solids are deposited at the bottom, and the wastewater stays in the pond for more than one day. The overflow water can be recycled, and sometimes it needs to be treated by neutralization, adsorption and oxidation according to requirements.

[0003] For the treatment of mineral processing wastewater, a large-flux security filter is generally used. The security filter generally includes a water inlet, a water outlet and an internal adsorption filter assembly. After a long time of use, the internal part needs to be cleaned by backwashing to ensure the long-term effect of filtration and adsorption.

[0004] In the prior art, the backwashing of the filter is generally carried out by introducing a large amount of water through the water outlet. For example, the utility model disclosed in the publication No. CN213823683U discloses a water filter with good backwashing effect. The water filter body is provided with a water inlet pipe on one side, a sewage discharge pipe on the side away from the water inlet pipe, a threaded layer on the inner side wall of the water filter body, an installation box inside the threaded layer, a moving block inside the installation box, a filter material box installed between the moving blocks, an arc-shaped groove opened in the inner side of the filter material box, an upper cover plate provided at the top end of the water filter body, a connecting block installed on the outer wall of the upper cover plate, and a recess formed in the inner part of the connecting block. To improve the filtering efficiency, the inner volume of the water filter is usually increased to accommodate larger filter cores or more filter materials. When backwashing the large water filter, the volume of the water filter cannot be changed, and the distance between the water inlet pipe and the sewage discharge pipe is relatively far. Therefore, the water filter needs to be filled with water to facilitate backwashing. To ensure the efficiency of backwashing, multiple water inletting and sewage discharging are usually required, which is slow and consumes a large amount of clean water, increasing the cost.

[0005] For the above technology, due to the filter element of the security filter or the filter material used is more, and the security filter usually only has one water inlet pipe, when backwashing the filter element, the single water inlet pipe is difficult to quickly flush the large area of the filter element surface, and the security filter usually needs to be additionally provided with a plurality of scrapers or cleaning brushes to clean the inner wall, so that the structure of the security filter is complex, and the dead angle of the scraper or the cleaning brush is easy to accumulate dirt, thereby reducing the cleaning effect.

Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor belong to the scope of protection of the utility model.

[0025] Please refer to Figures 1-3 The utility model provides technical scheme: a kind of mineral processing wastewater recycling backflushing large-flux security filter, including security filter body 1, water inlet 2 is fixed in the side of security filter body 1, water outlet 3 is fixed in one end of security filter body 1, it is characterized in that, fixed plate 4 being fixed in the inside of security filter body 1 is equipped in the end of water outlet 3, filter screen 5 is embedded in the inside of fixed plate 4, fixed plate 4 is rotatably connected with flux adjusting piece near the end of water outlet 3, the flux adjusting piece includes moving rod 6 being rotatably connected in the inside of fixed plate 4, recess for the one end of moving rod 6 is provided on fixed plate 4, the inside of security filter body 1 is also provided with moving plate 7, moving plate 7 is provided with driving member for driving moving plate 7 to move away from the end of fixed plate 4.

[0026] In the embodiment, water is introduced along water outlet 3 to perform backflushing, and the filter structure inside security filter body 1 and the inner wall of security filter body 1 are washed.

[0027] The flux adjusting piece is provided, and specifically, the flux adjusting piece includes crossbar 8 on fixed plate 4, hollow groove 9 is provided on crossbar 8, the area of filter screen 5 can be reduced by hollow groove 9, so as to avoid affecting normal filtration flux, rotating shaft 10 is rotatably connected in the inside of crossbar 8, moving rod 6 is fixed to the outside of rotating shaft 10, fixed rod 11 is further fixed to the side of crossbar 8, fan-shaped telescopic rubber plate 12 is connected between fixed rod 11 and moving rod 6, underwater motor 13 is connected to the end of rotating shaft 10 away from crossbar 8.

[0028] In the normal operation of the security filter body 1, the moving rod 6 and the fixed rod 11 are in close contact, and the fan-shaped telescopic rubber plate 12 between them is in a contracted state. At this time, the fan-shaped telescopic rubber plate 12 is in a state of not covering the filter screen 5, which ensures the normal operation of the security filter body 1.

[0029] A waist-shaped through groove 14 is arranged on the fan-shaped telescopic rubber plate 12, which is arranged near the edge of the fixed plate 4.

[0030] Meanwhile, the groove surface is bonded with a sealing rubber plate 15, and the middle part of the sealing rubber plate 15 is provided with an opening for the movement of the moving rod 6.
