[0027] The following description is intended to disclose the present invention so that those skilled in the art can implement it. The preferred embodiments described below are merely examples, and other obvious variations will occur to those skilled in the art.

[0028] Referring to Figures 1-4, a coal chemical wastewater treatment device includes a treatment tank 1. A coarse filter box 2 is fixedly connected to the upper surface of the treatment tank 1. A water inlet hopper 3 is fixedly connected to the upper end of the coarse filter box 2. An outlet 5 is opened through the rear side of the coarse filter box 2. A rotary motor 4 is fixedly installed on the left side of the coarse filter box 2. The output end of the rotary motor 4 passes through the left side of the coarse filter box 2 and is fixedly connected to a filter screen conveyor belt 7. Multiple evenly distributed partitions 8 are fixedly connected to the outer side of the filter screen conveyor belt 7. A baffle 6 is fixedly connected inside the outlet 5. A filter bucket 9 is fixedly connected to the bottom side of the inner wall of the treatment tank 1. A connecting plate 10 is fixedly connected to the lower end of the filter bucket 9. An auger shell 11 is fixedly connected inside the connecting plate 10.

[0029] Specifically, the treatment box 1 supports the coarse filter box 2 and the inlet hopper 3 on the coarse filter box 2. The inlet hopper 3 feeds wastewater into the coarse filter box 2, preventing spillage during transport. A rotary motor 4 on one side of the coarse filter box 2 drives the filter conveyor belt 7 inside the coarse filter box 2. The coarse filter box 2 supports the rotary motor 4. The filter conveyor belt 7 filters large solid impurities in the wastewater and transports them to the outlet 5, where they are discharged from the coarse filter box 2. The filter conveyor belt 7 is slightly raised at the end near the discharge port 5, which can effectively prevent wastewater from moving towards the discharge port 5 along with the filter conveyor belt 7. This can prevent wastewater from flowing out of the treatment box 1 and the coarse filter box 2 through the discharge port 5. Subsequently, the impurities are restricted in the partition formed between the two partitions 8 by the multiple baffles 8 set on the filter conveyor belt 7, thereby preventing the impurities from moving backward during the conveying process, which would prevent the impurities from being conveyed to the outside. At the same time, the baffle curtain 6 installed on the discharge port 5 can effectively block the wastewater moving with the impurities, making it even more difficult for the wastewater to flow out of the discharge port 5.

[0030] Referring to Figures 1-4, the auger housing 11 has an auger blade 12 inside. The outer surface of the auger housing 11 is fixedly connected to the bottom of the inner wall of the processing box 1. A drive motor 13 is fixedly installed at the front end of the auger housing 11. The output end of the drive motor 13 passes through the front end of the auger housing 11 and is fixedly connected to the auger blade 12. A discharge pipe 14 is connected to the right side of the auger housing 11. Two evenly distributed high baffles 15 and two evenly distributed low baffles 16 are fixedly connected inside the processing box 1.

[0031] Specifically, the fine impurities in the wastewater are filtered again through the filter hopper 9 below. The hopper-shaped filter hopper 9 allows the filtered impurities to collect at the bottom center, facilitating their discharge. The connecting plate 10 connects the auger shell 11 and the filter hopper 9 to prevent the impurities from mixing with the wastewater again during discharge. The drive motor 13 installed on the auger shell 11 drives the auger blades 12 inside the auger shell 11 to rotate, thereby conveying the impurities in the filter hopper 9 to the outside. The impurities are discharged through the discharge pipe 14 on the auger shell 11, facilitating their collection.

[0032] Referring to Figures 1-5, the bottom ends of the two low baffles 16 are fixedly connected to the bottom of the inner wall of the processing box 1. A servo motor 21 is fixedly installed on the front side of the processing box 1. The output end of the servo motor 21 is fixedly connected to the drive wheel 22 and rotatably connected to the front side of the processing box 1. Two symmetrically distributed driven wheels 20 are provided on the front side of the processing box 1. A transmission rod 19 is fixedly connected to the rear side of the two driven wheels 20. The outer surface of the transmission rod 19 is rotatably connected to the inside of the processing box 1. Threaded rods 17 are rotatably connected to the inside of the right high baffle 15 and the left low baffle 16. The rear ends of the two transmission rods 19 are fixedly connected to the threaded rods 17. Scrapers 18 are threadedly connected to the outer surfaces of the two threaded rods 17. The two ends of the scrapers 18 are slidably connected to the outer surfaces of the high baffle 15 and the low baffle 16, respectively.

[0033] Specifically, the gap between the high baffle 15 and the low baffle 16 facilitates wastewater flow. Wastewater flows through the gap below the high baffle 15 to the space between the high baffle 15 and the low baffle 16, and then flows above the low baffle 16 to the right side of the low baffle 16, thus achieving the effect of equal liquid levels on both sides and continuously sending wastewater to the right side. The servo motor 21 is supported by the treatment tank 1, and the servo motor 21 drives the drive wheel 22 to rotate, which in turn drives the two driven wheels 20 to rotate synchronously via a belt. At the same time, the treatment tank 1 restricts the transmission rod 19 connected to the driven wheel 20. The rotation of the driven wheel 20 drives the transmission rod 19 and the threaded rod 17 connected to the transmission rod 19 to rotate, thereby driving the scraper 18 on the threaded rod 17 to move back and forth, facilitating the removal of foam on the surface of the wastewater. The high baffle 15 and the low baffle 16 respectively restrict and support the two threaded rods 17.

[0034] Referring to Figures 1-6, overflow ports 29 are provided on both the front and rear sides of the treatment box 1, and chutes 23 are fixedly connected to both the front and rear sides of the treatment box 1; an air compressor 24 is fixedly installed on the rear side of the treatment box 1, and the output end of the air compressor 24 passes through the rear side of the treatment box 1 and is connected to an air supply pipe 25. A limit ring 28 is fixedly connected to the front end of the air supply pipe 25, and a swirl tube 26 is provided on the outer surface of the limit ring 28. A jet pipe 27 is fixedly connected to the front end of the swirl tube 26.

[0035] Specifically, two overflow ports 29 located on the front and rear sides of the treatment tank 1 facilitate the discharge of foam from the treatment tank 1. Two chutes 23 guide the discharged foam to prevent damage to the equipment. The treatment tank 1 supports the air compressor 24, which compresses external air and sends it into the treatment tank 1 through the air supply pipe 25. The gas is then mixed into the wastewater through the swirl pipe 26 and the jet pipe 27 connected to the air supply pipe 25. The irregularly shaped jet pipe 27 adjusts the flow direction of the gas, causing the two ends to flow in opposite directions, thus ensuring more uniform mixing of the gas in the wastewater. This allows the microbubbles to rise in the wastewater and come into contact with grease, suspended solids, and colloidal substances, carrying them upwards to form a foam layer for subsequent treatment.

[0036] Referring to Figures 1-7, a plurality of carrying plates 30 are provided on the right side of the processing box 1. A plurality of symmetrically distributed limiting blocks 32 are fixedly connected to both sides of the multiple carrying plates 30. The outer surface of the limiting blocks 32 is located inside the processing box 1. A placement plate 31 is fixedly connected inside the carrying plate 30. Two evenly distributed buckles 33 are fixedly connected to the left side of the carrying plate 30. The outer surface of the buckles 33 is located inside the right high baffle 15.

[0037] Specifically, the treatment box 1 supports and restricts multiple carrier plates 30, while the limiting blocks 32 on both sides of the carrier plates 30 restrict the carrier plates 30 inside the treatment box 1, and restrict the direction and trajectory of the carrier plates 30 inside the treatment box 1, thereby facilitating the subsequent replacement and cleaning of the carrier plates 30 and the placement plates 31 on the carrier plates 30. At the same time, the two buckles 33 on the left side of the carrier plates 30 fix the carrier plates 30 to the high baffle 15, thereby providing stable support for the use of the carrier plates 30. The activated carbon and zeolite on the placement plates 31 perform the final treatment of the wastewater, and the treatment effect is maximized through multi-layer synchronous adsorption.

[0038] Working principle: When in use, multiple carrier plates 30 filled with activated carbon and zeolite are inserted into the interior of the treatment box 1. The carrier plates 30 are fixed inside the treatment box 1 by the buckles 33 on the left side of the carrier plates 30, which facilitates subsequent use.

[0039] Wastewater to be treated is fed into the coarse filter box 2 through the inlet hopper 3 above it. At the same time, the rotary motor 4 on the left side of the coarse filter box 2 is started. The rotary motor 4 drives the filter screen conveyor belt 7 to rotate, and the solid impurities in the wastewater are filtered through the filter screen conveyor belt 7. The impurities are sent to the discharge port 5 through the rotating filter screen conveyor belt 7 and discharged through the discharge port 5. At the same time, the baffle curtain 6 installed on the discharge port 5 blocks the wastewater that does not fall, preventing the wastewater from flowing to the outside with the impurities. Thus, while filtering the wastewater, a large amount of wastewater is prevented from flowing out of the equipment.

[0040] The coarsely filtered wastewater then falls into the upper part of the filter hopper 9 for sedimentation. This causes the heavier impurities in the wastewater to fall to the bottom, while the lighter impurities float to the surface, making it easier to process the impurities later. The impurities and wastewater are separated by the filter hopper 9 below. The wastewater flows out through the gap between the lower side of the high baffle 15 and the treatment box 1, while the impurities flow towards the middle of the filter hopper 9. The drive motor 13 on the front side of the auger housing 11 drives the auger blades 12 to rotate, making it easier to extract the impurities from the filter hopper 9 through the auger blades 12, which facilitates the subsequent processing of the filtered material.

[0041] The filtered wastewater enters between the left low baffle 16 and the right high baffle 15. The air compressor 24 installed at the rear of the treatment box 1 compresses the air and sends it into the air supply pipe 25. The air is then sent into the treatment box 1 through the air supply pipe 25, the swirl pipe 26, and the jet pipe 27. At the same time, the high-speed ejected gas drives the jet pipe 27 to rotate at the front end of the air supply pipe 25 of the treatment box 1, which facilitates the injection of a large amount of gas into the wastewater. This allows the air bubbles to come into contact with the oil, suspended solids, and colloidal substances in the wastewater and adsorb them. This facilitates the treatment of the oil, suspended solids, and colloidal substances, which then form a foam layer that floats on the wastewater, making it easier for them to be treated in subsequent processes.

[0042] Then the servo motor 21 installed on the front side of the treatment tank 1 is started. The servo motor 21 drives the two threaded rods 17 connected to the drive wheel 22 and the driven wheel 20 to rotate, thereby driving the scraper 18 between the two threaded rods 17 to move on the water surface, thereby scraping off the foam layer on the water surface and discharging it through the overflow ports 29 on the front and rear sides of the treatment tank 1. Then the foam is collected through the chute 23 below to prevent the foam from affecting the equipment.

[0043] After impurities are removed again, the wastewater flows to the far right through the high baffle 15 and low baffle 16 on the right side. The activated carbon and zeolite on the multiple support plates 30 and placement plates 31 on the right side perform final adsorption treatment on the wastewater, making the wastewater treatment more complete and more in line with the requirements.

[0044] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments.
