Description

Technical Field

[0001] This utility model belongs to the technical field of wastewater treatment equipment, and in particular relates to a chemical wastewater treatment device. Background Technology

[0002] Chemical wastewater refers to process wastewater, cooling water, exhaust gas scrubbing water, and equipment and site washing water discharged during chemical production. If this wastewater is discharged without treatment, it will cause varying degrees of pollution to water bodies, thereby endangering human health and affecting industrial and agricultural production. Therefore, chemical wastewater treatment is necessary. The treatment of chemical wastewater requires the use of chemical agents to thoroughly mix with the wastewater and precipitate toxic substances.

[0003] However, in existing chemical wastewater treatment devices, when the supernatant is extracted after sedimentation, the turbid sediment at the bottom is easily drawn out. When filtering, a large amount of sediment can clog the filter, requiring frequent replacement, which is very troublesome. Utility Model Content

[0004] The purpose of this invention is to improve upon the shortcomings of existing technologies by proposing a chemical wastewater treatment device that effectively solves the problem that a large amount of precipitated material easily clogs the filter device during the extraction of the supernatant after sedimentation in chemical wastewater treatment devices, requiring frequent replacement.

[0005] The purpose of this utility model is achieved as follows: a chemical wastewater treatment device includes a support base, characterized by further including a sedimentation separation structure and a filtration structure. The sedimentation separation structure is located on the support base and is used to precipitate the chemical wastewater, separating it into precipitate and supernatant. The filtration structure is located on the side of the sedimentation separation structure, and the sedimentation separation structure and the filtration structure are connected by a water pumping pipe. The supernatant enters the filtration structure through the water pumping pipe. The filtration structure is used to filter and separate particulate matter that cannot be settled by the sedimentation separation structure, and the filtration separates the sludge into precipitate and clear water.

[0006] To further achieve the purpose of this utility model, the sedimentation separation structure may include a sedimentation tank, a separation seat, a leak, a chute, a partition, a hydraulic cylinder, a fixed seat, a motor, stirring teeth, and a drain valve. The sedimentation tank is fixedly mounted on a support base. The separation seat is located slightly below the center inside the sedimentation tank. The leak penetrates the center of the separation seat. The chute penetrates the leak and is horizontally positioned in the center of the separation seat. The partition is slidably mounted within the chute. One end of the hydraulic cylinder is fixed inside the separation seat, and the other end is fixed to the partition. The fixed seat is fixed to the support base. The motor is fixed to the fixed seat and drives the stirring teeth. The stirring teeth are located inside the sedimentation tank. The drain valve is located at the bottom of the sedimentation tank.

[0007] To further achieve the purpose of this utility model, the filter structure may include a filter tank, a filter layer, and a drain pipe, with the filter layer disposed inside the filter tank and the drain pipe disposed at the bottom of the filter tank.

[0008] To further achieve the purpose of this utility model, the partition can be provided in two sets, which can slide to the left and right respectively.

[0009] To further achieve the purpose of this utility model, the separation seat can be located at the lower two-thirds of the middle of the sedimentation tank.

[0010] To further achieve the purpose of this utility model, the water pumping pipe can be positioned above the separation seat.

[0011] To further achieve the purpose of this utility model, the separation seat can be configured as an inclined slope structure.

[0012] Compared with existing technologies, this utility model has the following significant features and positive effects: This utility model uses a sedimentation separation structure for preliminary sedimentation and filtration of waste liquid. The obtained precipitate is recovered and discharged, while the supernatant enters the filtration structure through a pumping pipe for filtration, filtering out particles that cannot be settled by the sedimentation separation structure. The filtered water is then discharged, effectively treating chemical wastewater. The structure is simple and reliable. The sedimentation separation structure uses an electric motor to drive the stirring teeth to mix the chemical agents evenly. It employs a structure with perforations, chutes, and baffles. The baffles seal the perforations, isolating the precipitate at the bottom of the sedimentation tank from the supernatant above, preventing the precipitate from being drawn out and clogging the filtration device. This effectively solves the problem of large amounts of precipitate clogging the filtration device and requiring frequent replacement when drawing out the supernatant after sedimentation in chemical wastewater treatment devices.

The sedimentation separation structure 2 is used to precipitate chemical wastewater, separating it into precipitate and supernatant. A filter structure 3 is located next to the sedimentation separation structure 2. The sedimentation separation structure 2 and the filter structure 3 are connected by a water pumping pipe 14. The supernatant produced by the sedimentation separation structure 2 enters the filter structure 3 through the water pumping pipe 14. The filter structure 3 is used to filter and separate particulate matter that cannot be settled by the sedimentation separation structure 2. The filtration separates particulate sludge and clear water. The particulate matter is recovered and the clear water is discharged. In this embodiment, the water pumping pipe 14 is fixedly located in the middle of the sedimentation tank 4 above the separation base 5.

[0019] Reference Figure 3 The sedimentation separation structure 2 includes a sedimentation tank 4, a separation seat 5, a leak 6, a chute 7, a baffle 8, a hydraulic cylinder 9, a fixed base 10, a motor 11, stirring teeth 12, and a drain valve 13. The sedimentation tank 4 is fixed on the support base 1. The separation seat 5 is located in the lower middle position inside the sedimentation tank 4. The separation seat 5 has an inclined slope structure. In this embodiment, the separation seat 5 is located in the lower two-thirds of the middle of the sedimentation tank 4. The leak 6 is set through the middle of the separation seat 5, and the chute 7 is set horizontally through the leak 6 in the middle of the separation seat 5. Plate 8 is slidably installed in the slide groove 7. One end of hydraulic cylinder 9 is fixed on the separation seat 5 and the other end is fixed on the partition plate 8. Fixed seat 10 is fixed on support seat 1. Motor 11 is fixed on fixed seat 10. Motor 11 is connected to drive stirring teeth 12. Stirring teeth 12 penetrate sedimentation tank 4 and are set inside sedimentation tank 4. Drain valve 13 is set at the bottom of sedimentation tank 4. In this embodiment, two sets of partition plates 8 are set. Each set of partition plates 8 is fixedly connected to a set of hydraulic cylinders 9.

[0021] In practical use, when using this device, the user first pours the chemical wastewater into the sedimentation tank 4, adds the chemical reagents into the chemical wastewater in the sedimentation tank 4, and then controls the motor 11 to drive the stirring teeth 12 to rotate, thereby mixing the chemical reagents evenly. Then, the rotation is stopped to allow static sedimentation. The precipitated material falls into the bottom of the sedimentation tank 4 through the leakage hole 6 in the middle of the separation seat 5. After the sedimentation is complete, the hydraulic cylinder 9 is controlled to push the baffle 8 to slide in the slide groove 7, so that the baffle 8 blocks the leakage hole 6. Then, the supernatant is drawn into the filter tank 15 through the water pumping pipe 14 and filtered through the filter layer 16. The particles that cannot settle are filtered out. Then, the filtered clean water is discharged through the drain pipe 17. The above is the entire process of using the chemical wastewater treatment device.
