[0048] The specific implementation of the present invention will be described below in conjunction with the accompanying drawings.

[0049] Embodiment 1:

[0050] like Figure 2-Figure 6 As shown, the fully automatic in-situ cleaning system for sanitary mixing equipment of this embodiment includes a tank body 1, a gear box 2 and a stirring paddle 3 are installed in the tank body 1, a discharge port 4 is provided at the center of the bottom wall of the tank body 1, and a steam port 5, a vacuum port, and a purge port are provided at intervals on the side wall of the tank body 1;

[0051] It also includes a main pipe 6, which is located above the outside of the tank body 1. A plurality of tee pipes 7 are installed on the main pipe 6. A first spray branch pipe 8 is installed on one joint of a single tee pipe 7. Meanwhile, a second spray branch pipe 9 is installed on the other joint of the single tee pipe 7. The first spray branch pipe 8 and the second spray branch pipe 9 are both located inside the tank body 1 and arranged around the gear box 2.

[0052] The ends of the first spray branch pipe 8 and the second spray branch pipe 9 are both equipped with spray balls 10;

[0053] The liquid in the main pipe 6 enters the first spray branch pipe 8 and the second spray branch pipe 9 respectively through the three-way pipe 7, and is then sprayed into the interior of the tank body 1 through the corresponding spray balls 10.

[0054] The spray ball 10 is arranged at an upper position inside the tank body 1 , so that the spray range of the spray ball 10 covers the upper surface of the inner wall of the tank body 1 and the upper surface of the outer wall of the gear box 2 .

[0055] The main pipe 6 , the first spray branch pipe 8 , and the second spray branch pipe 9 are all equipped with control valve components.

[0056] The gear box 2 is located above the stirring paddle 3 , and the stirring paddle 3 is connected to the output shaft of the gear box 2 .

[0057] The functions and working process of this embodiment are as follows:

[0058] The cleaning system of this embodiment includes a tank body 1, a gear box 2, a stirring paddle 3, a main pipe 6, a three-way pipe 7, a spray branch pipe (including a first spray branch pipe 8 and a second spray branch pipe 9), and a spray ball 10; wherein,

[0059] The main pipe 6 is connected to an external water source, which may be tap water or a cleaning agent; two tee pipes 7 are connected to the main pipe 6, and the liquid in the main pipe 6 is distributed to each spray branch pipe by setting the tee pipe 7, so as to be sprayed into the tank body 1 through the spray ball 10 connected to the spray branch pipe;

[0060] In this embodiment, in order to obtain a better spraying effect, the spray ball 10 is arranged at the upper position inside the tank body 1, so as to spray and clean the inner wall surface above the tank body 1 and the outer wall surface of the gear box 2;

[0061] The input shaft of the gearbox 2 is connected to the external driving device, and the output shaft is connected to the stirring paddle 3. The gearbox 2 itself can rotate relative to the tank body 1. The external driving device drives the stirring paddle 3 to rotate through the gearbox 2. The stirring paddle 3 can rotate around the axis of the tank body while rotating relative to its own axis.

[0062] The tank body 1 can be composed of multiple parts, but it needs to form a closed cavity in the end. The wall of the tank body 1 is provided with a discharge port 4, a steam port 5, a vacuum port and a purge port.

[0063] Among them, the discharge port 4 is opened in the center of the bottom wall of the tank body 1, so as to completely discharge the liquid inside the tank body 1 after cleaning is completed; the steam port 5 is used to introduce high-temperature steam into the interior of the tank body 1, the vacuum port is used to extract the gas inside the tank body 1 (including the gas components in the high-temperature steam), and the purge port is used to introduce gas into the interior of the tank body 1, and cooperate with the vacuum port to make the gas inside the tank body 1 flow, thereby accelerating the evaporation of water vapor inside the tank body 1 to make the inside of the tank body 1 dry.

[0064] When the tank body 1 is self-cleaned in place, the process is as follows:

[0065] First, high-position spray cleaning is performed: the cleaning liquid in the external water source flows into the first spray branch pipe 8 and the second spray branch pipe 9 through the main pipe 6 and the three-way pipe 7, and is sprayed to the inside of the tank body 1 through the corresponding spray ball 10, so as to clean the inner top wall and the upper part of the inner side wall of the tank body 1, and the outer top wall and the outer side wall of the gear box 2;

[0066] During the high-position spray cleaning process, the gear box 2 rotates slowly to ensure that the gear box 2 can be fully cleaned;

[0067] Secondly, perform low-mid cleaning: the cleaning liquid in the external water source is sequentially poured into the interior of the tank body 1 through the main pipe 6, the three-way pipe 7, the first spray branch pipe 8, the second spray branch pipe 9 and the spray ball 10. When the liquid level of the cleaning liquid in the tank body 1 is above the spray ball 10, the filling is stopped.

[0068] The gear box 2 keeps rotating by itself, and at the same time, the external driving device drives the stirring paddle 3 to rotate through the gear box 2, stirring the cleaning liquid inside the tank body 1, so that the cleaning liquid in the tank body 1 is driven by the stirring paddle 3 to achieve cleaning;

[0069] The stirring blade 3 and the gear box 2 are both set according to the working speed;

[0070] The cleaning liquid is a liquid that is harmless to the materials that the mixing equipment needs to handle, such as clean water, etc.

[0071] After the middle and low-level cleaning is completed, the cleaning liquid inside the tank body 1 is discharged through the discharge port 4;

[0072] Next, high-temperature steam sterilization is performed: high-temperature steam is added to the interior of the tank body 1 through the steam port 5. After the high-temperature steam evenly fills the entire tank body 1, it is maintained for a period of time for sterilization;

[0073] Finally, blow-drying is performed: the gas inside the tank body 1 is extracted through the vacuum port, and harmless gas is introduced into the interior of the tank body 1 through the purge port, and maintained for a period of time, so that the interior of the tank body 1 is finally dried.

[0080] The cleaning liquid is injected into the spray ball 10 through the main pipe 6, and the spray ball 10 sprays the cleaning liquid to the upper position inside the tank body 1, thereby spraying and cleaning the inner top wall surface and the upper position of the inner side wall surface of the tank body 1, and the outer top wall surface and the outer side wall surface of the gear box 2;

[0092] After the second set time, the cleaning liquid inside the tank body 1 is discharged to the outside of the tank body 1 through the discharge port 4, thereby completing the immersion cleaning;

[0093] S8. After the second set time, the immersion cleaning is completed, and the gear box 2 and the stirring paddle 3 stop rotating through the control system;

[0094] S9. Steam is then introduced into the interior of the tank body 1 through the steam port 5, so that the steam is evenly filled in the interior of the tank body 1;

[0095] S10. When the internal pressure of tank body 1 is ≥0.05MPa and the internal temperature of tank body 1 is ≥200°C, stop steam filling;
