Description

Technical Field

[0001] This utility model belongs to the field of wastewater treatment, specifically relating to a device for treating semi-coke wastewater. Background Technology

[0002] Semi-coke, also known as semi-coke, is a solid fuel produced by pyrolyzing coal at temperatures below the coking temperature. The production process of semi-coke generates a large amount of wastewater, which mainly contains high concentrations of pollutants such as phenols, cyanides, sulfides, and ammonia nitrogen. Direct discharge of this wastewater will have a serious impact on the environment.

[0003] Existing semi-coke wastewater treatment technologies mainly include physical, chemical, and biological methods. Physical methods, such as coagulation sedimentation and filtration, can remove some large particulate pollutants. However, current semi-coke wastewater treatment equipment often struggles to quickly mix flocculants with wastewater and is inconvenient to filter and discharge the generated flocculent precipitates, which requires further improvement.

[0004] Therefore, a treatment device for semi-coke wastewater is proposed, which can quickly mix flocculant with wastewater and facilitate the filtration and discharge of the generated flocculent precipitate. Utility Model Content

[0005] To overcome the problems of current semi-coke wastewater treatment devices, which often have difficulty in quickly mixing flocculants with wastewater and are inconvenient for filtering and discharging the generated flocculent precipitates, a treatment device for semi-coke wastewater is proposed.

[0006] The technical solution of this utility model is as follows: a treatment device for semi-coke wastewater, comprising a support box; a support plate is fixedly connected to the upper end of the support box, and two sets of support members are fixedly connected to the upper end of the support plate. Each set of support members includes two support rings, and a fixed cylinder is fixedly connected to the inner wall of the two support rings of each set of support members. A first stirring mechanism is provided on the inner wall of the fixed cylinder. A central cylinder is fixedly connected to the inner wall of the two fixed cylinders at their close ends. A feeding cylinder is fixedly connected through the upper end of the central cylinder. A second stirring mechanism is provided inside the feeding cylinder. Movable covers are slidably provided on the inner walls of the two fixed cylinders at their far ends. A liquid injection pipe is fixedly connected through one end of the fixed cylinder. A pushing mechanism for moving the movable cover is provided at the upper end of the support plate. The upper end of the support box is open. Two movable boxes are placed on the bottom surface inside the support box. Two first grooves are opened through the upper end of the support plate. The two first grooves are symmetrical about the central cylinder. The first grooves are located below the edge where the movable cover and the fixed cylinder fit together. The movable boxes are located below the first grooves. Two fixed columns are fixedly connected through the upper part of both ends of the movable boxes. Second grooves are opened through the lower part of both ends of the movable boxes. A filter screen is fixedly connected to the inner wall of the second groove.

[0007] Preferably, during use, semi-coke wastewater is injected into the interior of the movable hood through the injection pipe. The wastewater then enters the fixed cylinder and the central cylinder through the movable hood. Flocculant is then added into the central cylinder through the feeding cylinder. The first stirring mechanism is activated to stir the wastewater and flocculant in the fixed cylinder, and the second stirring mechanism is activated to stir the wastewater and flocculant in the central cylinder. When wastewater needs to be discharged, the pushing mechanism is activated to move the movable hood away from the central cylinder. The mixture then flows downward through the end of the fixed cylinder away from the central cylinder and falls into the movable box through the first tank. The water flows into the carrying box through the filter screen for temporary storage, while the sediment remains inside the movable box. This solves the problem that current semi-coke wastewater treatment devices often have difficulty in quickly mixing flocculant with wastewater and are inconvenient for filtering and discharging the generated flocculent sediment.

[0008] Preferably, the pushing mechanism includes a fixed ring, a U-shaped block, a roller, a fixed block, and an electric cylinder; a fixed ring is fixedly connected to the side wall of the movable cover, a U-shaped block is fixedly connected to the lower end of the fixed ring, rollers are rotatably installed on the inner walls of both sides of the U-shaped block, the lower end of the rollers is in contact with the upper end of the bearing plate, fixed blocks are fixedly connected to both sides of the U-shaped block, and electric cylinders are fixedly connected to the four corner edges of the upper end of the bearing box. The output shafts of two electric cylinders on the same side are arranged in opposite directions, and the output shafts of the electric cylinders are fixedly connected to the fixed blocks.

[0010] Preferably, a bend is fixed to the end of the injection tube away from the movable cover, and a first solenoid valve is installed on the bend.

[0011] Preferably, the first stirring mechanism includes a U-shaped frame, a fixed plate, a first motor, and a first stirring plate; the U-shaped frame is fixedly connected to the upper part of the inner wall of the fixed cylinder, the U-shaped frame is inverted U-shape, the fixed plate is fixedly connected to the middle of the lower end of the U-shaped frame, the first motor is fixedly connected to the end of the fixed plate away from the center of the central cylinder, the output shaft of the first motor passes through the fixed plate and is fixedly connected to the first stirring plate, and there is a gap between the lower end of the fixed plate and the bottom surface of the inner wall of the fixed cylinder.

[0012] Preferably, a third groove is provided through the upper part of both sides of the carrier box, and a waste liquid discharge pipe is fixedly connected through the lower part of one end of the carrier box, and a second solenoid valve is provided on the waste liquid discharge pipe.

[0014] The beneficial effects of this utility model are as follows: Semi-coke wastewater is injected into the interior of the movable hood through the injection pipe. The wastewater then enters the fixed cylinder and the central cylinder through the movable hood. Flocculant is then added into the central cylinder from the feeding cylinder. Activating the first stirring mechanism stirs the wastewater and flocculant in the fixed cylinder, and activating the second stirring mechanism stirs the wastewater and flocculant in the central cylinder. When wastewater needs to be discharged, the pushing mechanism is activated, causing the movable hood to move away from the central cylinder. The mixture then flows downwards through the end of the fixed cylinder away from the central cylinder and falls into the movable box through the first tank. The water flows through the filter screen into the carrying tank for temporary storage, while the sediment remains inside the movable box. This solves the problem that current semi-coke wastewater treatment devices often struggle to quickly mix flocculant with wastewater and are inconvenient for filtering and discharging the generated flocculent sediment.

[0035] When wastewater needs to be discharged, the pushing mechanism is activated to move the movable cover 7 away from the central cylinder 5. Specifically, the electric cylinder 20 is activated to push the fixed block 19, causing the fixed block 19 to move away from the central cylinder 5, and the movable cover 7 will move out from the inner wall of the fixed cylinder 4.
