Description

Technical Field

[0001] The utility model relates to the technical field of chemical wastewater treatment, in particular to a coal chemical wastewater treatment device. Background Art

[0002] Coal chemical wastewater refers to industrial wastewater generated during the chemical processing of coal. It is characterized by complex composition, high toxicity, many difficult-to-degrade substances, poor biodegradability, and large changes in water quality and quantity. The treatment of coal chemical wastewater is a technical challenge. The wastewater contains a large amount of organic pollutants, and these pollutants are often difficult to effectively remove through conventional biological treatment technologies.

[0003] The utility model with application number 202321876775.6 discloses a coal chemical wastewater treatment device. By arranging a scraper and a cylinder, impurities on the filter plate can be cleaned, the clogging of the filter plate is reduced, and the filtering efficiency of the equipment is improved. By arranging a connecting plate, a chute and a pulley, the scraper can push the impurities on the filter plate into the collection box, and can continue to move upward along the arc of the chute through the pulley under the push of the cylinder to the upper slide of the chute. At this time, when the scraper is retracted backward, its bottom has left the filter plate, and will not bring back the newly added or unremoved impurities on the filter plate, which greatly improves the quality and effect of cleaning. By arranging a water baffle, a spring and a top plate, untreated wastewater can be effectively blocked from entering the collection box, further improving the efficiency of wastewater treatment.

[0004] However, in the above-mentioned coal chemical industrial wastewater treatment device, when the multiple groups of filter layers in the filter box are inserted into the treatment device body for filtration, the water pressure is relatively high and the filter box cannot be replaced during the treatment process, which easily affects the wastewater treatment effect. The above-mentioned coal chemical wastewater treatment device only relies on physical treatment, mainly removing solid pollutants in suspended state in the sewage, and it is difficult to meet the emission standards. Therefore, the utility model proposes a coal chemical wastewater treatment device to solve the problems existing in the prior art. Utility Model Content

A sedimentation adsorption mechanism is provided on the other side of the sedimentation tank 1, and a sedimentation discharge mechanism is connected to the lower part of the sedimentation tank 1. When filtering is performed, wastewater enters the filter tank 2 and then enters the filter core 6 for filtration. When the filter core 6 needs to be replaced after long-term use, the lifting frame 5 is pulled up by the handle 7, and the filter core 6 is pulled out for quick and convenient replacement, which is convenient for replacement in the middle of wastewater filtration, thereby solving the problem that the filter box cannot be replaced during the wastewater filtration process.

[0020] The adsorption and sedimentation mechanism includes a precipitant box 8, a feeding bin 9, a feeding tray 10, a first motor 11, a feeding through-hole 12 and a rubber strip 13.

The output end of the first motor 11 is drivingly connected to the feeding tray 10, and the rubber strip 13 is in contact with the inner wall of the feeding bin 9. When the pollutants in the wastewater are adsorbed and precipitated, the precipitant is poured into the precipitant box 8, and the first motor 11 drives the feeding tray 10 to rotate so that the feeding through-hole 12 feeds a certain amount of precipitant into the sedimentation tank 1 at a uniform speed to adsorb and precipitate the pollutants in the wastewater.

[0021] One side below the feeding bin 9 is connected to the sedimentation tank 1 through a pipeline, and the other side above the feeding bin 9 is connected to the precipitant tank 8 through a pipeline, so that the precipitant can quickly enter the feeding bin 9.

[0023] A clean water pipe 22 is connected to the bottom of the other side of the filter tank 2, and a solenoid valve 23 is fixed on the clean water pipe 22. When the waste water is filtered through the filter element 6, it flows into the bottom of the filter tank 2. When draining the water, the solenoid valve 23 is opened to discharge the purified water from the clean water pipe 22.

[0024] The coal chemical wastewater treatment device pours wastewater into a sedimentation tank and then pours a precipitant into a precipitant box. The first motor starts to drive the feed plate to rotate, and the precipitant is quantitatively and uniformly fed into the sedimentation tank through the feed through hole, so as to facilitate the rapid adsorption and precipitation of organic matter in the wastewater. After static precipitation, the on-off valve is opened to allow the sediment and wastewater to enter the discharge pipe through the second drain pipe. The second motor drives the spiral auger to rotate to separate the wastewater from the sediment, so that the sediment is discharged from the sewage pipe into the collection box. The wastewater flows into the filter tank through the first drain pipe and is filtered by the filter element. When the filter element needs to be replaced after long-term use, the handle is pulled to lift the lifting frame and the filter element for easy replacement of the filter element. After the filtration is completed, the solenoid valve is opened to allow the filtered water to flow out from the clean water pipe.
