[0038] See also Figure 1 The utility model provides a storage tank internal cleaning device, comprising:

[0039] The power water supply 10 is used to provide a high-pressure aqueous solution to ensure sufficient flushing force and cleaning effect during the cleaning process, thereby effectively removing the residues and dirt in the tank.

[0040] The spraying part 20 is arranged at the top of the storage tank 80 and is connected to the power water supply 10 through the first water pipeline 21 to achieve top-down, comprehensive and uniform spraying. The first water pipeline 21 is installed with a first control valve assembly 22 to facilitate precise control of the spraying time and intensity to meet different cleaning needs.

[0041] The spray water supply integrated component is arranged at the bottom of the storage tank 80 and is connected to the power water supply 10 through the fourth water supply pipeline 30 to achieve cleaning coverage from bottom to top, and works in coordination with the spray component 20 to ensure full coverage of the cleaning area. The fourth water supply pipeline 30 is installed with a fourth control valve assembly 31, which can independently control the cleaning intensity of the bottom area.

[0042] The water ejector 40 has its inlet end connected to the power water supply point 10 through a second water pipeline 41, and a second control valve assembly 42 is installed on the second water pipeline 41 for adjusting the water flow entering the water ejector 40. A liquid recovery point 50 is provided at the water outlet end of the water ejector 40. The water ejector 40 is connected to the liquid recovery point 50 through a third water pipeline 43, and a third control valve assembly 44 is installed on the third water pipeline 43 to achieve effective recovery and recycling of waste water. The water ejector 40 is also connected to the spray water supply integrated component through a fifth water pipeline 60, and a fifth control valve 61 is installed on the fifth water pipeline 60. The fifth control valve 61 is used to control the on and off of the fifth water pipeline 60. The water ejector 40 is used to provide suction negative pressure to suck the cleaned liquid and impurities in the storage tank 80 to the liquid recovery point 50.

[0043] An aeration pipeline is laid at the bottom of the storage tank 80 and is connected to a blower. The aeration pipeline is used to inject gas into the tank to enhance the cleaning effect.

[0044] The control component is electrically connected to the first control valve assembly 22, the second control valve assembly 42, the third control valve assembly 44 and the fourth control valve assembly 31 to realize automatic control and regulation of the entire cleaning process, ensuring the safety, efficiency and energy saving of the cleaning process.

[0045] In this embodiment, a branch water pipeline 25 is further provided between the first control valve assembly 22 and the power water supply point 10. The function of the branch water pipeline 25 is to provide a branch water supply path for different cleaning components of the cleaning device, thereby increasing the flexibility and practicality of the device. One end of the branch water pipeline 25 is connected to the first water supply pipeline 21 to ensure a stable and sufficient water supply. A first communicating vessel 251 is installed at the other end of the branch water pipeline 25. The first communicating vessel 251 is provided with a first branch port and a second branch port. The water inlet ends of the second water supply pipeline 41 and the fourth water supply pipeline 30 are respectively installed on the first branch port and the second branch port, so that the ejector 40 and the spray water supply integrated component can obtain the required water flow from the same water source at the same time, thereby realizing flexible allocation of water flow and improving the integration and efficiency of the system.

[0046] A sixth manual valve 23 and a first pressure gauge 24 are also installed on the first water supply pipeline 21. The sixth manual valve 23 is arranged between the first control valve assembly 22 and the water inlet end of the branch water pipeline 25, and is used to manually adjust and control the water supply of the first water supply pipeline 21 to the spray element 20, while meeting the switching requirements of the cleaning device for the cleaning mode. The first pressure gauge 24 is arranged between the water inlet end of the branch water pipeline 25 and the power water supply point 10. The first pressure gauge 24 is electrically connected to the control component. The first pressure gauge 24 is used to monitor the water pressure at the water inlet end of the branch water pipeline 25 in real time. By accurately reading the pressure value, the water supply pressure can be ensured to be stable, and the normal operation and cleaning effect of the cleaning device can be guaranteed. When abnormal water pressure is detected, the control component can respond and adjust quickly to ensure the safe and stable operation of the cleaning device inside the storage tank 80.

[0047] The first control valve assembly 22 includes a first electric valve 221 and a first manual valve 222 installed in parallel on the first water supply pipeline 21. The first electric valve 221 is electrically connected to the control component, thereby realizing remote control and intelligent management of the first electric valve 221. The first manual valve 222 serves as a backup control means to ensure that under special circumstances, such as when the electric valve fails or manual adjustment is required, the normal operation of the cleaning system can still be maintained, thereby ensuring the overall reliability and safety of the cleaning device inside the storage tank 80.

[0048] Furthermore, a seventh manual valve 45 is installed on the second water supply pipeline 41, and the seventh manual valve 45 is arranged between the water inlet end of the second water supply pipeline 41 and the second control valve assembly 42, so that the water flow entering the second water supply pipeline 41 can be quickly manually controlled when necessary, so as to meet the cleaning mode switching requirements of the cleaning device, and can also effectively respond to emergencies. The second control valve assembly 42 includes a second electric valve 421 and a second manual valve 422 installed in parallel on the second water supply pipeline 41. The second electric valve 421 is electrically connected to the control component. The second electric valve 421 realizes precise regulation of the water flow through intelligent control, and realizes precise regulation of the negative pressure provided by the water ejector 40. The second manual valve 422 is used as a backup control means. When the second electric valve 421 fails or needs manual operation, the normal operation of the cleaning system can still be maintained, thereby ensuring the reliability and stability of the cleaning device inside the storage tank 80.

[0049] An eighth manual valve 46 is also installed on the third water pipeline 43, and the eighth manual valve 46 is arranged at the water outlet of the third water pipeline 43. This design allows the third water pipeline 43 to be quickly closed or adjusted in specific circumstances, such as when it is necessary to urgently cut off the waste liquid recovery path or perform manual adjustment, thereby ensuring the convenience and effectiveness of operation. The third control valve assembly 44 includes a third electric valve 441 and a third manual valve 442 installed in parallel on the third water pipeline 43. The third electric valve 441 is electrically connected to the control component. This combined design not only realizes the automated control of the waste liquid recovery process, but also retains the flexibility of manual operation. The third electric valve 441 can accurately control the flow of the waste liquid by connecting to the control component, thereby improving the efficiency of the cleaning process. The third manual valve 442 serves as a backup or auxiliary control means. When the third electric valve 441 fails or requires manual operation, it can ensure the smooth recovery of the waste liquid, thereby ensuring the stability and continuity of the cleaning operation.

[0050] The fourth control valve assembly 31 includes a fourth electric valve 311 and a fourth manual valve 312, and the fourth electric valve 311 and the fourth manual valve 312 are installed in sequence on the fourth water supply pipeline 30 along the water supply direction of the high-pressure aqueous solution. The fourth electric valve 311 is electrically connected to the control component, so that the supply of high-pressure aqueous solution to the spray water supply integrated component can be remotely controlled and automatically adjusted through the control system. The precise control of the fourth electric valve 311 ensures that the flow rate and pressure of the high-pressure aqueous solution can be flexibly adjusted according to the cleaning requirements, thereby optimizing the cleaning effect. At the same time, the fourth manual valve 312 serves as a backup control means. When the fourth electric valve 311 needs maintenance or in an emergency, it can be quickly switched to manual operation to ensure the continuity and safety of the cleaning operation. The dual control mechanism makes the internal cleaning device of the storage tank 80 both efficient and reliable in the high-pressure cleaning operation.

[0051] Furthermore, the fourth water supply pipeline 30 and the fifth water supply pipeline 60 are both connected to the spray water supply integrated component through a common pipeline 70. This design not only simplifies the pipeline system, but also reduces the cost and maintenance difficulty of the cleaning device. A second pressure gauge 71 is installed on the common pipeline 70. The second pressure gauge 71 is electrically connected to the control component. The second pressure gauge 71 can monitor the pressure conditions in the common pipeline 70 in real time. The operator can adjust the cleaning parameters according to the pressure data to ensure the safety and efficiency of the cleaning operation.

[0052] A plurality of aeration holes are provided on the aeration pipeline, and the aeration holes are used to release gas into the storage tank 80 during the flushing process to form a strong airflow disturbance, further increasing the contact area between the flushing liquid and the tank wall, so that the flushing liquid can penetrate more deeply into the tank wall surface and dead corners, thereby effectively removing stubborn dirt and residues and improving the flushing effect.

[0053] The high-pressure aqueous solution is any one of a cleaning solution and a reaction treatment solution, so that the cleaning device can flexibly select and use different types of solutions according to different cleaning requirements.

[0054] When the high-pressure aqueous solution is a cleaning solution, it can effectively remove dirt, grease and residue inside the storage tank 80, ensuring the cleanliness and hygiene standards of the tank body. The combination of the strong decontamination ability of the cleaning solution and the flushing effect of the high-pressure jet can thoroughly clean the tank body and extend its service life.

[0055] When the high-pressure aqueous solution is a reaction treatment solution, it can perform specific chemical reaction treatment on the inside of the storage tank 80 while cleaning. This solution can chemically react with specific pollutants on the surface of the tank, thereby more thoroughly removing these pollutants that are difficult to remove by physical cleaning. The addition of the reaction treatment solution makes the cleaning device inside the storage tank 80 more targeted and efficient in cleaning effect.

[0056] In another case, when it is necessary to discharge the cleaning waste water, the sixth manual valve 23 is used to block the connection between the first water supply pipeline 21 and the spray component 20, and then the fourth control valve assembly 31 is used to close the fourth water supply pipeline 30. At the same time, the power water supply 10 provides a reaction treatment solution, and the suction of the water ejector 40 is used to pump the cleaning waste liquid out of the storage tank 80 and mix it with the reaction treatment solution. The liquid recovery point 50 collects the water after the reaction treatment to achieve water reuse.
