Description

Technical Field

[0001] This application relates to the technical field of wastewater treatment, and in particular to a chemical storage tank for wastewater treatment. Background Technology

[0002] Sodium hypochlorite is often used as a wastewater treatment agent in industrial wastewater treatment. However, sodium hypochlorite has limited solubility in water. When the concentration is high and the settling time is long, it is easy to reach saturation, thereby precipitating solid particles and forming a precipitate.

[0003] Traditional chemical storage tanks are typically storage containers used to store wastewater treatment agents such as sodium hypochlorite. During wastewater treatment, the agents in the storage tank are added to the wastewater treatment system to mix and react with the wastewater. The addition of sodium hypochlorite during the wastewater treatment process is intermittent, and the agents remain in a static state in the storage tank during the intervals between additions.

[0004] Regarding the aforementioned technologies, since the prepared sodium hypochlorite reagent is in a static state in the storage tank, it is prone to precipitation. This leads to problems such as difficulty in controlling the reagent concentration or incomplete reaction process when the reagent is drawn from the storage tank for dosing, thus affecting the wastewater treatment effect. Utility Model Content

[0005] To prevent sodium hypochlorite from settling and thus improve the wastewater treatment effect, this application provides a storage tank for wastewater treatment.

[0006] This application provides a chemical storage tank for wastewater treatment, which adopts the following technical solution:

[0007] A chemical storage tank for wastewater treatment, comprising:

[0008] Medicine storage tank;

[0009] Feeding pipe, which is connected to the top of the medicine storage tank;

[0010] A discharge valve is provided on the discharge pipe;

[0011] The discharge pipe is connected to the bottom end of the side wall of the medicine storage tank;

[0012] An aeration component is installed on the drug storage tank and is used to blow air bubbles into the drug storage tank to prevent the drug from settling.

[0013] A stirring assembly is installed inside the medicine storage tank and is used to stir the medicine inside the medicine storage tank.

[0014] By adopting the above technical solution, water is poured into the storage tank through the feeding pipe to add sodium hypochlorite. The prepared reagent is controlled by the discharge valve and flows into the sewage treatment system through the discharge pipe. Air bubbles are blown into the storage tank through the aeration component. As the air bubbles rise, they agitate the sodium hypochlorite in the storage tank, causing the sodium hypochlorite particles that might otherwise settle to be carried away by the air bubbles. This effectively prevents the sodium hypochlorite from settling due to settling. The stirring component stirs the reagent in the storage tank, ensuring that the reagent is fully mixed and that the concentration of the reagent remains consistent. This further prevents the sodium hypochlorite from settling and improves the sewage treatment effect.

[0015] Optionally, the aeration assembly includes:

[0016] An air supply pipe is inserted through the bottom of the medicine storage tank and is fixedly connected to the medicine storage tank.

[0017] An air pump, which is fixedly installed on the air delivery pipe;

[0018] An aeration head, wherein there is at least one aeration head, the aeration head is connected to the top of the air supply pipe, and small holes are evenly distributed on the aeration head.

[0019] By adopting the above technical solution, the air pump delivers gas into the air delivery pipe, and then blows it out from the aeration head. The small holes evenly opened on the aeration head allow the gas to be released in the form of tiny bubbles, which increases the contact area between the bubbles and the agent. The aeration head is installed at the bottom of the storage tank, ensuring that the gas is delivered from the bottom of the storage tank upwards, so that the bubbles can better agitate the agent in the storage tank during the rising process, and avoid the agent from settling and settling.

[0020] Optionally, the stirring assembly includes:

[0021] The motor is fixedly mounted on the medicine storage tank at its fixed end.

[0022] A rotating shaft is fixedly installed at the output end of the motor and is disposed inside the medicine storage tank;

[0023] The blades are at least two in number and are fixedly mounted on the rotating shaft.

[0024] By adopting the above technical solution, the motor drives the rotating shaft to rotate, which in turn drives the blades to rotate. The blades can stir the agent in the storage tank. The rotation of the blades continuously promotes the flow of the agent, ensuring that sodium hypochlorite and water are fully mixed and of consistent concentration. The concentration of the agent output from the discharge pipe is stable, thereby improving the effect of wastewater treatment.

[0025] Optionally, an aeration membrane is fixedly installed on the aeration head.

[0026] By adopting the above technical solution, the aeration membrane can release gas more evenly. The gas diffuses through the tiny pores on the aeration membrane, forming finer bubbles and improving aeration efficiency. The aeration membrane can also act as a filter to prevent solvent from entering the aeration head and avoid clogging. When air is introduced, the micropores on the aeration membrane expand automatically to ensure air passage. When aeration stops, the micropores on the aeration membrane retract and close, ensuring the proper operation of the aeration assembly.

[0027] Optionally, a level gauge and a level display are fixedly installed on the storage tank, and the level gauge and the level display are electrically connected.

[0028] By adopting the above technical solution, the level gauge can accurately measure the liquid level height of the agent in the storage tank, and the level display will intuitively show the liquid level information measured by the level gauge, so as to ensure that the staff can accurately control the dosage ratio when adding water and sodium hypochlorite solute, so that the agent reaches the appropriate concentration range and improves the efficiency and quality of sewage treatment.

[0029] Optionally, a check valve is provided on the air supply pipe.

[0030] By adopting the above technical solution, the check valve can effectively prevent the gas in the gas delivery pipe from flowing back to the gas pump. When the gas pump stops working or malfunctions, the gas pressure in the gas delivery pipe becomes too high, causing gas backflow, which affects the normal operation and service life of the gas pump.

[0031] Optionally, the medicine storage tank is equipped with a controller, and the motor, the air pump, the discharge valve, and the check valve are all electrically connected to the controller.

[0032] By adopting the above technical solution, the controller enables centralized control of the related equipment of the medicine storage tank. Operators can use the controller to manage and operate the motor, air pump, discharge valve and check valve in a unified manner, without having to control each piece of equipment separately, thus improving the convenience and efficiency of operation.

[0033] Optionally, the aeration heads are evenly arranged at the bottom of the medicine storage tank.

[0034] By adopting the above technical solution, since the aeration heads are evenly arranged at the bottom of the storage tank, the bubbles released from the aeration heads can evenly agitate the medicine in different positions in the storage tank during the rising process, so that the medicine in the entire storage tank can be subjected to a relatively uniform stirring force, avoiding local unevenness or sedimentation.

[0035] In summary, this application includes at least one of the following beneficial technical effects:

[0036] 1. By installing aeration components, gas is blown upwards from the bottom of the storage tank, preventing sodium hypochlorite from settling and improving the wastewater treatment effect;

[0037] 2. By setting up a stirring component, the water and sodium hypochlorite solute in the storage tank are fully mixed and of consistent concentration. During the reaction between the reagent and the wastewater, the concentration of the reagent output from the discharge pipe is kept stable, thereby improving the wastewater treatment effect.

[0038] 3. By setting up a controller, automated control of the device is achieved, improving the convenience and efficiency of operation. Attached Figure Description

[0048] The following is in conjunction with the appendix Figure 1-4 This application will be described in further detail.

[0049] This application discloses a chemical storage tank for wastewater treatment.

[0050] Reference Figure 1 and Figure 2 The wastewater treatment chemical storage tank includes a storage tank 1, a feeding pipe 2, a discharge pipe 3, a discharge valve 4, an aeration assembly 5, and a stirring assembly 6. The storage tank 1 is a circular barrel shape. The feeding pipe 2 is connected to the top of the storage tank 1, and the discharge pipe 3 is connected to the bottom of the side wall of the storage tank 1. The discharge valve 4 is located on the discharge pipe 3. The aeration assembly 5 is installed on the storage tank 1 and is used to blow air bubbles into the storage tank 1 to prevent the chemicals from settling. The stirring assembly 6 is installed inside the storage tank 1 and is used to stir the chemicals within the storage tank 1.

[0051] In use, sodium hypochlorite and its aqueous solution are fed into the storage tank 1 through the feeding pipe 2. The aeration component 5 is activated to blow gas into the storage tank 1 to prevent the sodium hypochlorite from settling. The stirring component 6 is activated to stir the agent in the storage tank 1 in all directions, so that the solution concentration in the storage tank 1 is uniform. The stirring component 6 and the aeration component 5 work together to keep the agent in a suspended state and avoid the formation of sediment. When treating sewage, the agent enters the sewage treatment system from the discharge pipe 3 under the control of the discharge valve 4 to ensure the uniformity and stability of the agent, thereby improving the sewage treatment effect.

[0052] Reference Figure 3 and Figure 4 The aeration assembly 5 includes an air supply pipe 51, an air pump 52, and aeration heads 53. The air supply pipe 51 passes through the bottom of the side wall of the medicine storage tank 1 and is distributed at the bottom of the medicine storage tank 1. A check valve 10 is installed on the air supply pipe 51. The air supply pipe 51 is fixedly installed at the bottom of the medicine storage tank 1. The air pump 52 is fixedly connected to the air supply pipe 51. The aeration heads 53 are spherical crown shaped, and there are seven aeration heads 53. The seven aeration heads 53 are connected and arranged at the top of the air supply pipe 51, and the seven aeration heads 53 are evenly distributed at the bottom of the medicine storage tank 1. Small holes are evenly opened on the aeration heads 53. An aeration membrane 7 is fixedly installed on the aeration heads 53, and small holes are also evenly opened on the aeration membrane 7.

[0053] When in use, the air pump 52 is started, and the air pump 52 generates compressed air to deliver gas into the air supply pipe 51. The gas is released from the small holes evenly distributed on the aeration head 53 and the micro-holes on the aeration membrane 7, forming small bubbles. As the bubbles rise in the agent, they provide continuous bubble agitation for the agent in the storage tank 1, constantly stirring the agent and preventing the sodium hypochlorite agent from settling. When the air pump 52 is turned off, the compressed air in the air supply pipe 51 and the branch pipe tends to flow back to the air pump 52 due to excessive air pressure. The check valve 10 can effectively prevent the gas in the air supply pipe 51 and the branch pipe from flowing back to the air pump 52, extending the service life of the air pump 52. The aeration component 5 improves the uniformity and stability of the agent, thereby improving the wastewater treatment effect.

[0054] Reference Figure 1 and Figure 2 The stirring assembly 6 includes a motor 61, a rotating shaft 62, and impellers 63. The fixed end of the motor 61 is fixedly installed on the top of the medicine storage tank 1, and one end of the rotating shaft 62 is fixedly installed on the output end of the motor 61. The rotating shaft 62 is located inside the medicine storage tank 1. The eight impellers 63 are divided into two groups, and both groups of impellers 63 are distributed around the circumference of the rotating shaft 62 and fixedly installed on the rotating shaft 62.

[0055] When in use, start the motor 61, which drives the rotating shaft 62 to rotate. The rotating shaft 62 drives the blades 63 to rotate, stirring the medicine in the storage tank 1. The two sets of blades 63 increase the stirring area and force, which can more effectively mix the medicine in the storage tank 1 and prevent uneven mixing of the medicine, which would affect the subsequent sewage treatment effect.

[0056] Reference Figure 1 and Figure 2 A level gauge 8 is fixedly installed on the upper inner wall of the medicine storage tank 1, and a level display 9 is fixedly installed on the top outer wall of the medicine storage tank 1. The level gauge 8 and the level display 9 are electrically connected.

[0057] During use, the level gauge 8 monitors the liquid level of the agent in the tank in real time and transmits the liquid level information to the level display 9 in the form of an electrical signal, ensuring that the amount of agent and solution added will not exceed the capacity limit of the storage tank 1. At the same time, when adding solvent and sodium hypochlorite, the staff controls the ratio of solvent and agent added through the level display 9 to make the solution reach the required concentration, thereby improving the efficiency and quality of sewage treatment.

[0058] Reference Figure 1 and Figure 2 A controller 11 is installed on the outer surface of the medicine storage tank 1. The motor 61, air pump 52, discharge valve 4 and check valve 10 are all electrically connected to the controller 11.

[0059] In use, when treating sewage, the operator can start the motor 61 and the air pump 52 through the controller 11 to start the stirring component 6 and the aeration component 5. When the sewage treatment system needs chemicals, the controller 11 opens the discharge valve 4 to allow the chemicals to flow into the sewage treatment system for reaction. When the air pump 52 stops working or malfunctions, the controller 11 automatically controls the check valve 10 to close, preventing the gas in the storage tank 1 from flowing back to the air pump 52, thus improving the convenience and efficiency of operation.

[0060] The implementation principle of a chemical storage tank for sewage treatment in this application embodiment is as follows: The chemical storage tank 1 provides storage space for sewage treatment agents. Sodium hypochlorite and water can be added to the chemical storage tank 1 through the feeding pipe 2. During the sewage treatment process, the air pump 52 generates compressed air, which is sent into the tank from the bottom of the chemical storage tank 1 through the air supply pipe 51, dispersing the gas to different positions. Then, tiny bubbles are released from the top aeration head 53. The bubbles rise in the agent, disturbing the agent and preventing sedimentation. The aeration membrane 7 makes the bubbles more uniform and smaller, while preventing impurities from entering the aeration head 53 and preventing the agent from contaminating the aeration head 53.

[0061] Simultaneously, controller 11 controls motor 61 to drive shaft 62 to rotate, and blades 63 on shaft 62 rotate accordingly, stirring the medicine to ensure thorough mixing and uniformity. Level gauge 8 monitors the liquid level in the tank in real time and transmits the information to level display 9 on the top of the outer wall of storage tank 1, allowing operators to easily monitor the medicine's quantity and consumption and replenish it promptly.

[0062] The controller 11 on the outer surface of the storage tank 1 centrally controls the motor 61, air pump 52, discharge valve 4 and check valve 10. The storage tank 1 used for sewage treatment can effectively prevent the precipitation of the agent, ensure the uniformity and stability of the agent, provide high-quality agents for sewage treatment, and improve the efficiency and effect of sewage treatment.

[0063] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
