Description

Technical Field

[0001] The utility model belongs to the technical field related to wastewater treatment, and specifically relates to a device for treating graphite wastewater by utilizing magnetic force. Background Art

[0002] Graphite plays a huge role in the economic growth process with its excellent performance. With the increasing demand for graphite deep-processing products in the domestic and foreign markets, the graphite production process has brought pollution. The treatment of graphite production wastewater has become one of the problems that the industry needs to solve urgently. The existing wastewater treatment device for the graphite production process is inefficient in actual use, and the structure is too simple, and the treatment is not clean enough, so that the discharged sewage has a negative impact on the ecological environment and is not green and environmentally friendly. Patent No.: CN202120166782.1 discloses a graphite production wastewater treatment device, which is provided with a booster plate and a connecting pipe in the primary reaction box, and the sewage passing through the double-layer filter screen is collected together by the booster plate, so that the sewage flushes the connecting pipe directly into the activated carbon filter box, reducing the time that the sewage stays on the filter screen, shortening the reaction time of treating the sewage, and improving the work efficiency. A film and an inclined plate are provided inside the infiltration device, and the film is provided with multiple layers and is inclined, so that the sewage is infiltrated and filtered layer by layer, and automatically flows downward under the action of its own weight without manual operation. Then the inclined plate can control the discharged water flow rate, reduce the impact force on the drain pipe connection port, and extend the service life of the equipment. During the sedimentation process in the sedimentation tank of the device, flocculants need to be added to make the sewage settle at the bottom of the sedimentation tank. The method of using flocculants to accelerate sedimentation requires continuous addition of flocculants during sewage treatment, which is relatively costly. The flocculent sediment will adhere to the bottom and inner wall of the sedimentation tank, making it inconvenient to remove and process.

[0003] In view of this, the present utility model is proposed. Utility Model Content

Air port 23, a high-pressure air pump 15 is fixedly installed in the middle position above the electromagnetic force rod 3, and lifting hydraulic cylinders 14 are symmetrically arranged on both sides of the high-pressure air pump 15. The upper end of the lifting hydraulic cylinder 14 is fixedly connected to the movable support plate 13, and the movable support plate 13 is slidably connected to the support rail 10. The support rail 10 is fixedly installed on the support frame 8, and a moving block 12 is fixedly arranged on the movable support plate 13. A translation hydraulic cylinder 9 is fixedly installed on the top of the support frame 8, and the translation hydraulic cylinder 9 is used to drive the movable support plate 13 to move horizontally.

[0027] Among them, a movable slide groove 11 is opened on the support rail 10, and sliding side plates 24 are fixedly arranged at both ends of the movable support plate 13. A rolling support groove 25 is opened on the sliding side plate 24, and a movable roller 26 is installed in the rolling support groove 25. The setting of the movable roller 26 makes the moving process of the movable support plate 13 more convenient and stable.

[0028] The sedimentation box 1 is provided with a water inlet 6 above the sewage electric push rod 5, a drain outlet 16 is provided on the other side of the sedimentation box 1, and a sedimentation sewage outlet 4 is provided on the outer side of the sedimentation box 1 below one end of the drain outlet 16 for discharging the precipitated flocs.

[0029] A guide slope 18 is provided at one end of the permanent magnet block 17 above the drain outlet 16, and a floc collection groove 21 is formed between the permanent magnet block 17 at the lower end of the guide slope 18 and the bottom of the sedimentation box 1. The sedimentation sewage outlet 4 is set at a position corresponding to the floc collection groove 21 to facilitate the discharge of the precipitated flocs.

[0030] A decontamination receiving box 7 is provided between the sedimentation box 1 and the support frame 8 . The size of the decontamination receiving box 7 is larger than that of the sealing top cover 2 , so as to facilitate blowing the flocs on the electromagnetic force rod 3 into the decontamination receiving box 7 .

[0031] A sealing sleeve 20 is provided at the matching position between the sewage discharge electric push rod 5 and the sedimentation box 1 to ensure the sealing performance in the sedimentation box 1 during the telescopic movement of the sewage discharge electric push rod 5 .

[0032] Stainless steel magnetic wool is arranged on the outer diameter of the electromagnetic force rod 3 to improve the ability of pollutants to be trapped on the electromagnetic force rod 3.

[0033] The working principle of the utility model is as follows: when graphite wastewater is treated, the graphite wastewater treated in the previous process is supplied to the sedimentation box 1 through the water purification port, and the permanent magnet block 17 and the electromagnetic force rod 3 in the sedimentation box 1 generate a magnetic field. The wastewater passes through the magnetic field, and the magnetic particles in the water are magnetized to form a small magnet with north and south poles. Since the magnetic field gradient is zero, it is subjected to forces of equal magnitude and opposite direction, and the resultant force is zero. The particles are not captured by the magnetic field, but the particles attract each other and gather into large particles. After the wastewater passes through the magnetic field, since the magnetic particles have a certain coercive force, they can continue to produce a cohesion effect, and a part of the floccules are precipitated and adsorbed on the permanent magnet block 17, and a part of the floccules are adsorbed on the electromagnetic force rod 3. The wastewater treated by precipitation is discharged from the drain port 16 under the action of the water pump;

[0034] When cleaning the precipitated flocs, the sewage electric push rod 5 is extended, and the flocs attached to the permanent magnetic block 17 are pushed and scraped to the guide slope 18 by the decontamination push plate 19, and finally slide into the floc collection tank 21, and are discharged from the sedimentation sewage outlet 4 by the slurry pump. When cleaning the flocs on the electromagnetic force rod 3, the lifting hydraulic cylinder 14 is contracted to lift the sealing top cover 2 upward, so that the electromagnetic force rod 3 is taken out from the sedimentation box 1, and the telescopic rod of the translation hydraulic cylinder 9 is contracted to drive the sealing top cover 2 to move to the top of the decontamination receiving box 7, and the high-pressure air pump 15 works to blow high-pressure gas to the electromagnetic force rod 3 through the blowing port, so that the flocs are separated from the electromagnetic force rod 3 for cleaning, and can be rotated as needed to use high-pressure water for spraying to ensure the cleaning effect;

[0035] The novel structure of the present invention is reasonably designed and easy to install and use. A permanent magnet block 17 is arranged at the bottom of the sedimentation box 1, and an electromagnetic force rod 3 is arranged on the sealing top cover 2. The graphite wastewater in the sedimentation box 1 can be precipitated by using the permanent magnet block 17 and the electromagnetic force rod 3. The wastewater passes through the magnetic field, and the magnetic particles in the water are magnetized and gathered into large particles. A blowing port is opened on the sealing top cover 2 between the electromagnetic force rods 3, and the flocs on the electromagnetic force rods 3 can be cleared by high-pressure gas. A decontamination push plate 19 is arranged in the sedimentation box 1, which can clear the flocs on the permanent magnet block 17, which can not only improve the sedimentation treatment efficiency, but also reduce the wastewater treatment cost.
