Description

Technical Field

[0001] This utility model relates to the field of wastewater treatment devices, and more specifically, to a wastewater treatment device based on an alkali-plated copper printing roller. Background Technology

[0002] In the manufacturing process of printing rollers, while traditional nickel plating imparts certain properties to the rollers, it generates wastewater containing the heavy metal nickel. Nickel is a stable heavy metal and extremely difficult to degrade in the natural environment. Therefore, some companies use alkaline copper plating instead of nickel plating in printing roller production to relatively reduce pollution (alkaline copper is relatively less harmful to the environment. Although copper is also a heavy metal, within a certain concentration range, its toxicity to the environment and organisms is lower than that of nickel).

[0003] The wastewater generated from the production of printing rollers using alkali copper plating instead of nickel plating requires multiple processes during treatment, including preliminary sedimentation, neutralization reaction, and biological treatment. These processes are interconnected and work together to ensure that the wastewater meets purification standards. However, traditional wastewater treatment devices are all integrated units. This design makes the entire treatment process highly automated. After one step is completed, the wastewater is automatically transported to the next step until the treatment process is finished. This makes it difficult for staff to sample and test the alkali copper plating wastewater processed in each step in real time (it requires opening different tanks, which is quite cumbersome. This is because the tanks are usually designed with a sealing structure to ensure the stability of the wastewater treatment process and prevent leakage. Opening and closing these sealing devices requires certain professional operating skills and tools. At the same time, the weight of the tank lids increases the complexity of the operation). As a result, it is difficult to detect failures in a certain step in time, which seriously affects the efficiency of wastewater treatment.

[0004] Therefore, in order to solve the above-mentioned technical problems, this application proposes a wastewater treatment device based on alkali-plated copper printing rollers. Utility Model Content

[0005] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a wastewater treatment device based on alkali-plated copper printing roller.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a wastewater treatment device based on an alkali-plated copper printing roller, comprising a base and a plurality of wastewater treatment tanks disposed thereon, wherein the wastewater treatment tanks are interconnected by connecting pipes, a water pump A is installed at the outlet of each wastewater treatment tank, and an electric three-way ball valve is installed at the end of the water pump A, wherein the two outlets of the electric three-way ball valve are respectively connected to the connecting pipe and the drain pipe, and the opening of the drain pipe faces downward.

[0007] Preferably, the top of the sewage treatment tank is provided with a limiting groove that is directly opposite the drain pipe, and a sampling container is placed inside the groove to limit the position of the sampling container.

[0008] Preferably, a funnel is installed at the bottom of the drain pipe to concentrate the flow and prevent splashing.

[0009] Preferably, a water collection tank is also installed at the top of the base. The top of the water collection tank is connected to the water inlet pipe via a water pump B. The head of the first sewage treatment tank for treating sewage is connected to the water transport pipe via a water pump C. The water transport pipe is connected to the water collection tank.

[0010] Preferably, the wastewater treatment tank includes a preliminary sedimentation tank, a neutralization reaction tank, a biological treatment tank, a secondary sedimentation tank, and a deep treatment tank.

[0011] Preferably, the water collection tank is equipped with an automatic water filling device, which works in conjunction with the water pump B to ensure sufficient water in the collection tank. This eliminates the need for manual water filling, saving manpower and maintaining the stable operation of the sewage treatment device.

[0012] Preferably, the automatic water filling device includes:

[0013] Liquid level sensor: It is installed inside the water collection tank to detect the liquid level information in the water collection tank in real time and send the signal to the microprocessor;

[0014] Microprocessor: Used to receive signals from the liquid level sensor. When the liquid level sensor detects that the liquid level in the collection tank is lower than the preset minimum value, the controller will send a signal to the actuator to drive water pump B to run. When the liquid level sensor detects that the liquid level in the collection tank is higher than the preset maximum value, it will send a signal to the actuator to shut down water pump B.

[0015] Actuator: Drives water pump B to run or stop running based on signals from the microprocessor;

[0016] Power supply: Provides power to the electrical components on the automatic water filling device.

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] 1. When sampling and inspection are required, this utility model only needs to adjust the electric three-way ball valve to be connected to the drain pipe. In this way, the sewage can be discharged in a small amount through the electric three-way valve from the drain pipe by the water pump A for sampling. The operation is relatively simple and convenient for staff to discover the fault in a certain process in time, thereby solving the problem in the background technology that makes it difficult for staff to sample and test the alkaline copper plating sewage processed in each process in real time.

[0019] 2. This utility model can limit the sampling container through the limiting groove, so that it can stably receive the wastewater discharged from the drain pipe, and at the same time the funnel can concentrate the flow to avoid splashing.

[0020] 3. The stable sewage flow provided by the water collection tank of this utility model enables these sewage treatment tanks to operate stably within the design parameter range and fully utilize their treatment capacity;

[0021] 4. The water collection tank of this utility model is equipped with an automatic water filling device, which works in conjunction with water pump B to ensure that the water volume in the collection tank is sufficient. This eliminates the need for manual water filling, saving manpower and maintaining the stable operation of the sewage treatment device. Attached Figure Description

[0027] like Figures 1-3 As shown, this utility model provides a wastewater treatment device based on alkali-plated copper printing roller, including a base 8 and a plurality of wastewater treatment tanks 1 disposed thereon. The wastewater treatment tanks 1 are interconnected by connecting pipes 2. A water pump A3 is installed at the outlet of the wastewater treatment tank 1. An electric three-way ball valve 4 is installed at the end of the water pump A3. The two outlets of the electric three-way ball valve 4 are respectively connected to the connecting pipe 2 and the drain pipe 5. The opening of the drain pipe 5 faces downward.

[0028] Among them, the wastewater treatment tank 1 includes a preliminary sedimentation tank, a neutralization reaction tank, a biological treatment tank, a secondary sedimentation tank, and a deep treatment tank (it should be noted that only some of the wastewater treatment tanks are shown in the attached figure). Through these wastewater treatment tanks 1, the alkali-plated copper wastewater generated from the production of alkali-plated copper printing plate rollers can be deeply treated to meet the discharge standards. The following is a detailed introduction to each wastewater treatment tank 1.

[0029] Preliminary sedimentation tank: Wastewater generated during the production of alkali-plated copper printing rollers is discharged into this tank, where it settles and large particles settle to the bottom of the tank under gravity. A sludge scraper periodically scrapes the settled impurities to the sludge discharge port for discharge.

[0030] Neutralization tank: After primary sedimentation, the wastewater flows into the neutralization tank. Based on the acidity and alkalinity test results of the wastewater, an appropriate amount of acid-base regulator is added to the tank through the dosing device. At the same time, the stirring device is started to fully mix the agent with the wastewater and adjust the acidity and alkalinity of the wastewater to a suitable range.

[0031] Biological treatment tank: Neutralized wastewater enters the biological treatment tank, where air is continuously introduced through an aeration device. Microorganisms grow and reproduce in an aerobic environment using biological packing material, and decompose the organic matter in the wastewater.

[0032] Secondary sedimentation tank: Wastewater after biological treatment flows into this tank, where activated sludge settles to the bottom under the action of inclined tube packing. Part of the sludge is returned to the biological treatment tank via a sludge return pump, while the other part is discharged through the sludge discharge port.

[0033] Advanced treatment tank: Wastewater after secondary sedimentation enters the advanced treatment tank and passes through the filter layer and activated carbon adsorption layer in sequence to remove fine particulate impurities, residual organic matter and pigments from the wastewater, so that the treated wastewater meets the discharge standards or reuse requirements.

[0034] After the previous wastewater treatment tank 1 finishes treating the wastewater, the electric three-way ball valve 4 is adjusted to connect with the connecting pipe 2. Then, the water pump A3 can be run. The water pump A3 provides power to transport the wastewater through the electric three-way ball valve 4 and the connecting pipe 2 to the next wastewater treatment tank 1. When sampling is required, simply adjust the electric three-way ball valve 4 to connect with the drain pipe 5. In this way, the water pump A3 can discharge a small amount of wastewater from the drain pipe 5 through the electric three-way valve for sampling (at this time, the flow rate needs to be reduced by the electric three-way ball valve 4, and the power of the water pump A3 needs to be reduced to avoid discharging too much wastewater). The operation is relatively simple and convenient for staff to detect faults in a certain process in a timely manner.

[0035] Furthermore, a funnel 15 is installed at the bottom of the drain pipe 5, and a limiting groove 6 is opened at the top of the sewage treatment tank 1, which is directly opposite to the drain pipe 5. A sampling container 7 is placed inside the groove. This way, the sampling container 7 can be limited by the limiting groove 6, so that it can stably receive the wastewater discharged from the drain pipe 5. At the same time, the funnel 15 collects the water and prevents splashing.

[0036] Furthermore, a water collection tank 9 is installed at the top of the base 8. The top of the water collection tank 9 is connected to the inlet pipe 11 via a water pump B10. The head of the first wastewater treatment tank 1, which treats wastewater, is connected to the water transport pipe 13 via a water pump C12. The water transport pipe 13 is connected to the water collection tank 9. In this way, the water pump B10 can add sufficient wastewater to the water collection tank 9 through the inlet pipe 11, and then the water pump C12 can input the wastewater into the wastewater treatment tank 1 through the water transport pipe 13 for treatment. This ensures that there is a sufficient amount of wastewater input into the wastewater treatment tank 1 for treatment within a certain period of time. This is because various processes in wastewater treatment, such as sedimentation, filtration, and aeration, require appropriate flow and load conditions to achieve optimal performance. The stable wastewater flow provided by the water collection tank 9 allows these wastewater treatment tanks 1 to operate stably within the design parameter range and fully utilize their treatment capacity. For example, sedimentation under stable water flow conditions can more effectively achieve solid-liquid separation and improve the clarity of the effluent; aeration under appropriate wastewater flow conditions can ensure sufficient mixing of oxygen and wastewater, improve aeration efficiency, and promote the oxidative decomposition of organic matter.

[0037] It should be noted that the volume of the water collection tank 9 is much larger than that of the sewage treatment tank 1, thus enabling it to hold a sufficient amount of wastewater. At the same time, the diameter of the inlet pipe 11 is also much larger than that of the connecting pipe 2 and the water transport pipe 13, and the power of the water pump B10 is also much greater than that of the water pump A3 and the water pump C12, thereby improving the efficiency of adding water to the water collection tank 9.

[0038] Meanwhile, this utility model also installs an automatic water filling device 14 on the water collection tank 9, which works in conjunction with the water pump B10 to ensure that the water volume in the water collection tank 9 is sufficient. This eliminates the need for manual operation to add water, saving manpower and maintaining the stable operation of the sewage treatment device. The automatic water filling device 14 includes a liquid level sensor, a microprocessor, an actuator, and a power supply.

[0039] The liquid level sensor is installed inside the water collection tank 9, and its core function is to monitor the liquid level in the tank in real time. Like a keen "observer," it constantly monitors changes in the liquid level in the tank and transmits this information to the microprocessor as a signal. The microprocessor acts as the "brain" of the entire automatic water filling device 14, responsible for receiving signals from the liquid level sensor. When the microprocessor receives a signal from the liquid level sensor indicating that the liquid level in the tank 9 is lower than the preset minimum value, it is like receiving a "water shortage alarm." At this time, it sends a signal to the actuator to drive the water pump B10, causing the water pump B10 to act on the inlet pipe 11 to start adding sewage into the tank 9. Conversely, when the signal received by the microprocessor indicates that the liquid level in the tank 9 is higher than the preset maximum value, i.e., it receives the "water is sufficient" information, it sends a signal to the actuator to shut off the water pump B10, thus stopping the addition of sewage into the tank 9 and stopping the water pump B10 from operating. The actuator acts like an "executor," strictly following the signals issued by the microprocessor to drive the water pump B to run or stop running, thereby realizing the automatic addition of water to the water collection tank 9. All electrical components in the automatic water addition device 14, including the level sensor, microprocessor, and actuator, are powered by a power source to ensure their normal operation and guarantee the stable operation of the entire automatic water addition system.

However, any modifications, alterations, or equivalent variations made by those skilled in the art without departing from the scope of the utility model's technical solution, utilizing the disclosed technical content, are considered equivalent embodiments of this utility model.
