Description

Technical Field

[0001] The utility model relates to the field of coal water purification, in particular to a coal water purification device. Background Art

[0002] Coal is a flammable substance that is flammable when exposed to fire or high temperature. Coal ash is easily blown into dust by wind, causing damage to the air. In order to prevent spontaneous combustion and dust from coal, coal mines, power plants and fuel companies regularly spray and wash the coal with water to cool it down and prevent combustion, and avoid generating dust. However, the coal sludge water used for coal washing contains a large amount of suspended solid pollutants such as particulate coal and particulate coal ash, and the water is black in color. Direct discharge will inevitably cause water pollution. Moreover, the solid pollutants contained in the coal ash water are mostly particulate coal and coal ash. Direct discharge will also cause energy loss. Therefore, the coal sludge water should be purified to achieve the purpose of water purification and secondary utilization of pollutants.

[0003] According to the high-efficiency coal water purifier device proposed in the patent with publication number CN210481008U, the high-efficiency coal water purifier device introduces coal water into the purifier device through a water inlet pipe and a booster nozzle, and the conical hole inside the booster nozzle causes the coal water to be ejected under high pressure, thereby accelerating the filtration of the coal water inside the inclined tube, and the filter holes and filter cotton on the partition plate preliminarily filter the larger impurities in the coal water, and then the trace elements in the coal water are filtered and adsorbed by the honeycomb filter plate, and the pure water is diverted to the bottom of the tank body through the drain cap and discharged through the drain pipe, so as to achieve the effect of high-efficiency multiple filtration and purification. However, the high-efficiency coal water purifier device only removes impurities and trace elements in the coal water through physical filtration, and because the coal water also contains a large amount of heavy metals and suspended matter, etc., which cannot be purified by the existing patent, it is necessary to add a coagulant to make the coal water and the agent fully mixed to form flocculent precipitation before it can be removed. Therefore, the existing patent is not thorough in purifying the coal water, and it will still have an impact on the ecological environment after discharge. Utility Model Content

The sieve plate 5 can be vibrated by the recovery process after rotation, which can improve the filtering efficiency of the sieve plate 5 and prevent the sieve plate 5 from being blocked, thereby ensuring the filtering effect. The bottom of the treatment box 1 is horizontally rotated with a stirring rod 6 driven by a motor, and a plurality of stirring plates 7 are arranged in an array along the axial direction on the stirring rod 6. One side of the treatment box 1 is provided with a dosing port 8 connected to the inside of the treatment box 1. After the impurities are removed by filtration, the coal water falls into the bottom of the treatment box 1, and a coagulant is added into the treatment box 1 through the dosing port 8. At the same time, the stirring rod 6 drives the plurality of stirring plates 7 to rotate under the drive of the motor, so that the coagulant and the coal water are evenly stirred and mixed, so that the heavy metals and suspended matter in the coal water form floccules and precipitate, so as to purify the coal water more thoroughly and avoid the impact on the ecological environment after discharge.

[0021] Preferably, a plurality of flow disturbance mechanisms 9 are arranged in an array along the axial direction on the stirring rod 6, and the flow disturbance mechanisms 9 are staggered with the stirring plate 7. The flow disturbance mechanisms can stir the coal and water in a direction different from the rotation direction of the stirring plate during the stirring process, thereby disturbing the coal and water, improving the stirring efficiency of the coagulant aid and the coal and water, and making the stirring more uniform.

[0022] Preferably, the spoiler mechanism 9 includes a connecting rod 10, the axis of the connecting rod 10 is perpendicular to the axis of the stirring rod 6, a mounting cylinder 11 is rotatably provided on the connecting rod 10, the rotation direction of the mounting cylinder 11 is perpendicular to the rotation direction of the stirring rod 6, and a plurality of spoiler blades 12 are arranged in a circumferential circular array on the outer side of the mounting cylinder 11, and the plurality of spoiler blades 12 are arranged at an angle to the horizontal plane, as shown in the attached Figure 2As shown, when the stirring rod 6 drives the connecting rod 10 to rotate, the inclined surface of the spoiler blade 12 cuts the water flow, so that the water flow applies a reaction force to the spoiler blade 12, and the spoiler blade 12 is pushed to rotate under the guidance of the inclined surface of the spoiler blade 12. While the stirring plate 7 rotates and stirs the coal-water vertically, the rotating spoiler blade 12 rotates and stirs the coal-water horizontally, which has a disturbing effect on the coal-water, so that the coal-water is stirred disorderly, which can greatly increase the mixing rate of the coagulant aid and the coal-water, ensure uniform mixing, and the spoiler blade 12 is driven by water power, which saves the use of electrical components and is simpler to install and use.

[0023] Preferably, the vibration mechanism includes a rotating shaft 13 rotatably arranged in the processing box 1, and the rotating shaft 13 is driven to rotate by a motor. A plurality of paddles 14 are arranged on the rotating shaft 13 in a circumferential circular array. The end of the paddle 14 away from the rotating shaft 13 can paddle the sieve plate 5 in the direction opposite to the water flow. The rotating shaft 13 drives the paddle 14 to rotate, so that the plurality of paddles 14 paddle one of the sieve plates 5 at regular intervals, so that all the sieve plates 5 rotate slightly at the same time, and return to their original positions under the action of gravity and the impact of the water flow, thereby playing the role of vibrating the sieve plate 5.

[0024] Preferably, a downwardly inclined guide slope 15 is provided at the bottom of the processing box 1, and the discharge port 3 is arranged at the lowest point of the guide slope 15 to facilitate the accumulation of sediment, thereby facilitating the centralized collection and treatment of the sediment in the processing box 1.

[0025] Preferably, the plurality of sieve plates 5 are connected by a traction rope 16 to achieve linkage between the plurality of sieve plates 5 .

[0026] Preferably, the bottom of the sieve plate 5 is rotatably connected to the guide plate 4 by a torsion spring, and the sieve plate 5 is rotated and opened in the direction of the water flow by the elastic force of the torsion spring, and the rotation angle of the sieve plate 5 relative to the guide plate 4 is 80-100°, so that the maximum angle position of the sieve plate 5 and the guide plate 4 is slightly greater than the vertical state, and the paddle plate 14 rotates to paddle the sieve plate 5 to cause the torsion spring to be compressed and deformed. After the paddle plate 14 leaves the sieve plate 5, the paddle plate 14 rebounds to the starting position under the action of the torsion spring, so that the vibration of the sieve plate 5 is stronger, and it can also prevent the sieve plate 5 from fitting with the guide plate 4 after excessive rotation.

[0027] Working principle: after the coal water enters the treatment box 1 from the feed port 2, it flows along the guide plate 4 and passes through a plurality of sieve plates 5 arranged in descending order in sieve hole diameter. During the process, the paddle plate 14 rotates regularly to paddle the plurality of sieve plates 5 to rotate and squeeze the torsion spring. After the paddle plate 14 is separated from the sieve plate 5, the sieve plate 5 is rebounded to the starting position under the action of the torsion spring, so that the sieve plate 5 vibrates to ensure a better filtering effect; the filtered coal water falls into the bottom of the treatment box 1, and the coagulant is added into the treatment box 1. The motor drives the stirring plate 7 and the connecting rod 10 to rotate, so that the stirring plate 7 stirs the coal water in the vertical direction, and the coal water is stirred in the horizontal direction through the spoiler blade 12, so that the coal water is stirred disorderly, and the stirring rate is increased. After that, it is allowed to settle. The sediment gathers at the discharge port 3 along the guide slope 15, which is convenient for the centralized collection and treatment of the sediment in the treatment box 1 to complete the purification of the coal water. In order to achieve a better effect, the inclination directions of the guide plate 4 and the guide slope 15 are opposite.

[0028] Through this patent, the coal water can be graded and filtered and purified multiple times to ensure a good filtering effect. After that, the coagulant is evenly stirred and mixed with the coal water to make the heavy metals and suspended matter in the coal water form floccules and precipitate, so as to purify the coal water more thoroughly, meet the user's needs, and avoid the impact on the ecological environment after discharge.
