Technical Field

[0001] This utility model belongs to the technical field of wastewater treatment, specifically relating to a wastewater treatment device for red-based KD production. Background Technology

[0002] The Red Base KD production wastewater treatment device is a complete set of treatment facilities designed for wastewater containing aniline compounds, organic solvents, acidic and alkaline substances, and high concentrations of organic matter generated during the production process. It integrates units such as neutralization and adjustment, precipitation and separation, solvent recovery by distillation, activated carbon adsorption, and biochemical treatment (such as anaerobic-aerobic processes) to remove toxic substances from the wastewater, reduce COD and salt concentration, and ensure that the treated water meets discharge standards or reuse requirements.

[0003] However, existing wastewater treatment devices for red-based KD production filter filter immediately after adding the reagents, resulting in a short reaction time and inconsistent wastewater treatment. Furthermore, time is wasted when replacing the filter screen, leading to low production efficiency. Utility Model Content

[0004] The purpose of this invention is to provide a wastewater treatment device for red-based KD production, in order to solve the problems mentioned in the background art of existing red-based KD production wastewater treatment devices, which filter immediately after adding the reagents, resulting in a short reaction time for the reagents and a discontinuous wastewater treatment process. At the same time, time is wasted when replacing the filter screen, leading to low production efficiency.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a red-based KD production wastewater treatment device, comprising a reaction tank;

[0006] A wastewater pipe is installed at the top of the reaction tank, and a stirring motor is installed at the middle of the top of the reaction tank.

[0007] A filter cylinder is installed at the bottom of the reaction tank, an inlet is installed on the upper left side of the filter cylinder, and an outlet is installed at the bottom of the filter cylinder.

[0008] Preferably, a roller is provided inside the filter cylinder, and a filter screen replacement door is provided on the upper right side of the filter cylinder.

[0009] Preferably, the outer side of the roller is provided with eight filter screens in a circular array, and the inside of the roller is provided with grippers corresponding to the filter screens.

[0010] Preferably, the filter screen is provided with docking grooves on the left and right sides, and the docking grooves are provided with embedded grooves inside the docking grooves.

[0011] Preferably, the docking groove corresponds to the gripper, and the filter screen is nested and connected to the gripper through the groove.

[0012] Preferably, the reaction chambers are arranged in a ring array of three, a wastewater pump is installed at the top of the reaction chambers, and a reagent pump is installed at the top right side of the reaction chambers.

[0013] Preferably, the reagent pipe is located at the top of the wastewater treatment device, and a branch pipe is located at the bottom of the reagent pipe. The reagent pipe is connected to the reagent pump through the branch pipe, and the wastewater pipe is connected to the wastewater pump through the branch pipe. A connecting plate is located at the bottom of the reaction tank, and the reaction tank is connected to the connecting plate through a connecting pipe. A valve is located in the middle of the connecting pipe, and the wastewater pumps of the reaction tank are used alternately.

[0014] Preferably, the connecting plate is connected to the filter cartridge via a water inlet, and the filter cartridge has an inspection door on its side.

[0015] Compared with the prior art, this utility model provides a wastewater treatment device for red-based KD production, which has the following beneficial effects:

[0016] 1. Through the design of the filter cylinder, inlet, outlet, roller, filter screen replacement door, filter screen, clamp, docking groove, and embedding groove, the filter cylinder is located at the bottom of the reaction tank, allowing the wastewater after the reaction to directly enter the filter cylinder for filtration. This shortens the wastewater's transmission path within the device and improves overall treatment efficiency. The reasonable placement of the inlet and outlet ensures a relatively stable water flow within the filter cylinder, guaranteeing thorough filtration and efficient removal of impurities. The filter screen replacement door located on the upper right side of the filter cylinder facilitates easy replacement of the filter screen. The filter screen offers convenience. When it becomes clogged or damaged after a period of use, there is no need to disassemble the entire filter cartridge. Simply open the filter screen replacement door to operate. Eight filter screens are arranged in a circular array on the outside of the drum, increasing the filtration area and improving the filtration effect. At the same time, the drum is equipped with clamps corresponding to the filter screens, and docking grooves are set on the left and right sides of the filter screens. The grooves in the docking grooves are nested and connected with the clamps. This design ensures that the filter screens are firmly installed on the drum, preventing the filter screens from shifting or falling off during wastewater filtration, and ensuring the stability and reliability of filtration.

[0017] 2. The reactor is arranged in a circular array of three units, including wastewater pumps, reagent pumps, reagent pipes, branch pipes, connecting plates, and valves. The wastewater pumps in each reactor operate alternately. This design enables continuous wastewater treatment. While one reactor is treating wastewater, the others can prepare or be in different treatment stages, significantly improving the overall wastewater treatment capacity and efficiency. This meets the treatment needs of large-scale red-based KD production wastewater. A reagent pump is located on the top right side of the reactor, and a reagent pipe is located on the top of the wastewater treatment unit. The reagent pipe is connected to the reagent pump via branch pipes. This arrangement allows for precise control of the reagent dosage, adjusting according to different reactions. The specific condition of the wastewater inside the tank is precisely controlled by a reagent pump, which injects an appropriate amount of reagent into the reaction tank to ensure the stability and effectiveness of the wastewater treatment. The bottom of the reaction tank is connected to a connecting plate via a connecting pipe. A valve is installed in the middle of the connecting pipe. By controlling the opening and closing of the valve, the outflow of wastewater in the reaction tank can be flexibly adjusted. According to the treatment progress and needs, the wastewater can be rationally arranged to enter the connecting plate for subsequent treatment, ensuring the orderly progress of the entire treatment process. The wastewater pipe is connected to the wastewater pump via a branch pipe. This layout is compact and reasonable, simplifying pipe connections, reducing the footprint, and also reducing the risk of pipe blockage and leakage, thereby improving the stability and reliability of the device.

Detailed Implementation

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] This utility model provides, for example Figure 1-4 The red-based KD production wastewater treatment device shown includes a reaction tank 1;

[0025] Wastewater pipe 2 is installed at the top of reaction tank 1, and stirring motor 17 is installed at the middle of the top of reaction tank 1;

[0026] A filter cylinder 7 is installed at the bottom of the reaction chamber 1, an inlet 11 is installed on the upper left side of the filter cylinder 7, and an outlet 10 is installed at the bottom of the filter cylinder 7.

[0027] A roller 14 is installed inside the filter cartridge 7, and a filter replacement door 8 is installed on the upper right side of the filter cartridge 7.

[0028] Eight filters 15 are arranged in a ring array on the outer side of the roller 14, and grippers 16 corresponding to the filters 15 are arranged inside the roller 14.

[0029] The filter screen 15 has docking grooves 20 on both sides, and the docking grooves 20 have embedded grooves 18 inside.

[0030] The docking groove 20 corresponds to the clamp 16, and the filter screen 15 is nested and connected to the clamp 16 through the groove 18.

[0031] The reaction chamber 1 is arranged in a ring array of three. A wastewater pump 13 is installed at the top of the reaction chamber 1, and a reagent pump 19 is installed at the top right side of the reaction chamber 1.

[0032] A chemical pipe 3 is installed at the top of the wastewater treatment device, and a branch pipe 12 is installed at the bottom of the chemical pipe 3. The chemical pipe 3 is connected to the chemical pump 19 through the branch pipe 12. The wastewater pipe 2 is connected to the wastewater pump 13 through the branch pipe 12. A connecting plate 6 is installed at the bottom of the reaction tank 1. The reaction tank 1 is connected to the connecting plate 6 through a connecting pipe 4. A valve 5 is installed in the middle of the connecting pipe 4. The wastewater pump 13 of the reaction tank 1 is used alternately.

[0033] The connecting plate 6 is connected to the filter cartridge 7 via the water inlet 11, and the filter cartridge 7 has an inspection door 9 on its side.

[0034] In this embodiment, the specific implementation steps of a red-based KD production wastewater treatment device are as follows: Red-based KD production wastewater flows in from wastewater pipe 2 and, under the action of wastewater pump 13, enters one of the reaction tanks 1 through branch pipe 12. Simultaneously, the reagent used to treat the wastewater flows from reagent pipe 3 and, under the action of reagent pump 19, is also injected into the reaction tank 1 through branch pipe 12. The stirring motor 17 is started to stir and mix the wastewater and reagent in the reaction tank 1, ensuring sufficient contact and chemical reaction between the reagent and wastewater, thus initially treating the pollutants in the wastewater. After a certain reaction time, the valve 5 on the connecting pipe 4 is opened, and the treated wastewater flows into the connecting plate 6 through the connecting pipe 4. Since there are three reaction tanks 1 and the wastewater pumps 13 are used alternately, the wastewater can be rationally arranged to enter different reaction tanks for treatment according to the actual treatment situation, thereby improving efficiency. In terms of overall processing efficiency, wastewater in the connecting plate 6 enters the filter cylinder 7 through the inlet 11. Inside the filter cylinder 7, the wastewater is filtered by the filter screens 15 arranged in a ring array on the outside of the drum 14, removing impurities and unreacted substances from the wastewater. The filtered water flows out from the outlet 10 at the bottom of the filter cylinder 7, completing one cycle of wastewater treatment. As the usage time increases, if the filter screen 15 becomes clogged and affects the filtration effect, the filter screen replacement door 8 can be opened, the clamp 16 and the filter screen 15 can be loosened, and the old filter screen can be removed from the drum 14 through the groove 18. Then, a new filter screen can be installed, ensuring that the clamp 16 and the filter screen 15 are tightly nested together through the groove 18. If it is necessary to inspect or repair the inside of the filter cylinder 7, the inspection door 9 on the side of the filter cylinder 7 can be opened to enter the interior for corresponding operations.

[0035] like Figure 1 and Figure 3 As shown, a filter cylinder 7 is installed at the bottom of the reaction tank 1. An inlet 11 is installed on the upper left side of the filter cylinder 7, and an outlet 10 is installed at the bottom of the filter cylinder 7. A roller 14 is installed inside the filter cylinder 7. A filter screen replacement door 8 is installed on the upper right side of the filter cylinder 7. Eight filter screens 15 are arranged in a circular array on the outer side of the roller 14. A clamp 16 corresponding to the filter screen 15 is installed inside the roller 14. A docking groove 20 is installed on the left and right sides of the filter screen 15. An embedded groove 18 is installed inside the docking groove 20. The docking groove 20 corresponds to the clamp 16. The filter screen 15 is nested and connected to the clamp 16 through the embedded groove 18.

[0036] Preferably, the filter cartridge 7 is located at the bottom of the reaction tank 1, allowing the wastewater after the reaction to directly enter the filter cartridge 7 for filtration. This shortens the wastewater's transmission path within the device and improves overall treatment efficiency. Through the rational arrangement of the inlet 11 and outlet 10, the wastewater can form a relatively stable flow within the filter cartridge 7, ensuring that the wastewater passes fully through the filter screen 15, achieving efficient filtration and effectively removing impurities from the wastewater. The filter screen replacement door 8 located on the upper right side of the filter cartridge 7 provides convenience for replacing the filter screen 15. When the filter screen 15 becomes clogged or damaged after a period of use... No complicated disassembly of the entire filter cylinder 7 is required; operation can be performed simply by opening the filter replacement door 8. Eight filter screens 15 are arranged in a circular array on the outer side of the drum 14, which increases the filtration area and improves the filtration effect. At the same time, the drum 14 is equipped with grippers 16 corresponding to the filter screens 15. The left and right sides of the filter screens 15 are provided with docking grooves 20, and the grooves 18 in the docking grooves 20 are nested and connected with the grippers 16. This design ensures that the filter screens 15 are firmly installed on the drum 14, preventing the filter screens 15 from shifting or falling off during the wastewater filtration process, and ensuring the stability and reliability of filtration.

[0037] like Figure 1 and Figure 4 As shown, three reaction chambers 1 are arranged in a circular array. A wastewater pump 13 is installed at the top of reaction chamber 1, a reagent pump 19 is installed at the top right side of reaction chamber 1, a reagent pipe 3 is installed at the top of the wastewater treatment device, a branch pipe 12 is installed at the bottom of reagent pipe 3, and reagent pipe 3 is connected to reagent pump 19 through branch pipe 12. Wastewater pipe 2 is connected to wastewater pump 13 through branch pipe 12. A connecting plate 6 is installed at the bottom of reaction chamber 1, and reaction chamber 1 is connected to connecting plate 6 through connecting pipe 4. A valve 5 is installed in the middle of connecting pipe 4. The wastewater pumps 13 of reaction chamber 1 are used alternately.

[0038] Preferably, three reaction chambers 1 are arranged in a circular array, and the wastewater pumps 13 of the reaction chambers 1 are used alternately. This design enables continuous wastewater treatment. While one reaction chamber 1 is treating wastewater, the other reaction chambers 1 can be preparing or in different treatment stages, greatly improving the overall wastewater treatment capacity and efficiency, and meeting the treatment needs of large-scale red-based KD production wastewater. A reagent pump 19 is installed on the top right side of the reaction chamber 1, and a reagent pipe 3 is installed on the top of the wastewater treatment device. The reagent pipe 3 is connected to the reagent pump 19 through a branch pipe 12. This arrangement can accurately control the amount of reagent added. According to the specific conditions of the wastewater in different reaction chambers 1, the dosage can be adjusted by adding reagents. The agent pump 19 precisely injects an appropriate amount of agent into the reaction tank 1, ensuring the stability and effectiveness of the wastewater treatment. The bottom of the reaction tank 1 is connected to the connecting plate 6 via a connecting pipe 4. A valve 5 is installed in the middle of the connecting pipe 4. By controlling the opening and closing of the valve 5, the outflow of wastewater in the reaction tank 1 can be flexibly adjusted. According to the treatment progress and needs, the wastewater can be reasonably arranged to enter the connecting plate 6 for subsequent treatment, ensuring the orderly progress of the entire treatment process. The wastewater pipe 2 is connected to the wastewater pump 13 via a branch pipe 12. This layout is compact and reasonable, simplifying pipe connections, reducing the floor space, and also reducing the risk of pipe blockage and leakage, thus improving the stability and reliability of the device.

[0039] like Figure 1-4 As shown, the connecting plate 6 is connected to the filter cylinder 7 through the water inlet 11, and the filter cylinder 7 is provided with an inspection door 9 on its side.

[0040] Optionally, the connecting plate 6 is connected to the filter cartridge 7 via the water inlet 11. This direct and reasonable connection method allows the wastewater after preliminary treatment in the reaction tank 1 to flow smoothly and efficiently into the filter cartridge 7 for further filtration. The stable water flow path helps ensure the consistency of the filtration effect, such as the inspection, maintenance or replacement of the filter screen 15, roller 14, etc. By opening the inspection door 9, the staff can directly enter the interior of the filter cartridge 7 without the need for complicated disassembly of the entire filter cartridge 7, which greatly saves maintenance time and costs, and also reduces the impact of long-term equipment downtime on production, ensuring the long-term stable operation of the equipment.

[0041] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
