[0029] The technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments.

[0030] Unless otherwise defined, all technical and scientific terms used in this application have the same meaning as those commonly understood by those skilled in the art to which this application belongs. The terms used in the specification of this application are only for the purpose of describing specific embodiments and are not intended to limit this application.

[0031] In order to further illustrate the technical means and effects adopted by this application to achieve the intended purpose, the following detailed description of this application is made in conjunction with the accompanying drawings and preferred implementation methods.

[0032] Please also refer to Figure 1 and Figure 2 The tank structure 100 provided in the embodiment of the present application includes a tank body 10, a tank cover 30, a bracket 50 and a control module 70. The tank cover 30 is arranged on the tank body 10 and is connected to the tank body 10 in an openable and closable manner to form a closed accommodating space 20, and the accommodating space 20 is used to hold materials. The bracket 50 is connected to the tank body 10 to support the tank body 10, and a moving wheel 51 is provided at one end of the bracket 50 away from the tank body 10 to drive the tank body 10 to move. The control module 70 includes a sensing component 71 and a control component 73. The sensing component 71 is arranged in the accommodating space 20 for obtaining parameters in the tank body 10, and the control component 73 is arranged on the outside of the tank body 10. Specifically, the control component 73 is arranged on the side wall of the tank body 10. The control component 73 is electrically connected to the sensing component 71 for receiving the parameters of the sensing component 71 and for generating a control signal.

[0033] Specifically, the tank structure 100 is used to hold liquid materials, such as those used in the biological, chemical, and pharmaceutical fields. A support 50 with movable wheels 51 is provided to drive the tank structure 100 for movement, thereby facilitating transfer within a continuous flow system. A control module 70 is provided on the sidewall of the tank body 10 to facilitate real-time monitoring of the parameters of the liquid within the storage space 20, thereby ensuring the liquid's condition during transfer.

[0034] The tank lid 30 is provided with a feed pipe 31, which is used to connect the accommodating space 20 with the exterior of the tank structure 100 to allow material to be filled into the accommodating space 20. The feed pipe 31 bends within the accommodating space 20 toward the sidewall of the tank body 10, so that the end of the feed pipe 31 is close to the sidewall of the tank body 10. Specifically, the feed pipe 31 passes through the tank lid 30 and is fixed thereto. One end of the feed pipe 31, located outside the accommodating space 20, is used to receive external material. The feed pipe 31 may be provided with a valve to control the opening and closing of the feed pipe 31 to ensure the sealing effect of the tank structure 100. The portion of the feed pipe 31 within the accommodating space 20 is bent toward the side wall of the tank body 10 so that the pipe opening at the end of the feed pipe 31 is close to the side wall of the tank body 10, so that when the material enters the accommodating space 20 through the feed pipe 31, it will flow down along the side wall of the tank body 10, thereby avoiding falling directly to the bottom of the tank body 10 and causing bubbling or splashing, which is beneficial to improving the stability of the material.

[0035] In some embodiments, the feed tube 31 may be L-shaped, with one end of the L-shaped feed tube 31 passing through the tank cover 30 to connect the accommodating space 20 with the external environment. The inflection point of the L-shape of the feed tube 31 is located within the accommodating space 20, so that the other end of the L-shaped feed tube 31 bends toward the side wall of the tank body 10, thereby positioning the end of the feed tube 31 near the side wall of the tank body 10. In other embodiments, the feed tube 31 may also have other shapes, which are not limited in this application.

[0036] The tank lid 30 is also provided with a breather 33. Specifically, the breather 33 is used to connect the accommodating space 20 to the outside world to balance the pressure inside and outside the tank structure 100. Specifically, when material is placed in the accommodating space 20, chemical reactions of the material itself or temperature changes within the accommodating space 20 can cause a pressure difference between the accommodating space 20 and the external environment. If the pressure difference is too high, it may cause damage to the tank structure 100. Therefore, the breather 33 is provided to balance the pressure inside and outside the tank structure 100. The breather 33 is an openable and closable structure. When the breather 33 is open, the accommodating space 20 is connected to the external environment of the tank structure 100, allowing air to circulate in and out of the tank structure 100, thereby balancing the pressure between the accommodating space 20 and the external environment. When the breather 33 is closed, the accommodating space 20 remains sealed.

[0037] A filter element 331 can also be provided on the respirator 33. The filter element 331 is located on the passage connecting the respirator 33 with the accommodating space 20 and the external environment, and is used to filter the gas passing through the respirator 33, so that the inside and outside of the tank structure 100 are relatively isolated, preventing the material in the accommodating space 20 from contaminating the external environment, or the external environment from contaminating the material in the accommodating space 20.

[0038] The tank cover 30 is also provided with a spray module 35, which includes a spray head 351 located in the accommodating space 20 and an interface 353 connected to the spray head 351. The other end of the interface 353 is connected to the outside of the tank structure 100 through the tank cover 30. Specifically, the spray module 35 is used to perform a cleaning process on the inside of the tank structure 100. Among them, the interface 353 is used to receive the cleaning liquid supplied from the outside. The spray head 351 is provided with a plurality of through holes. The cleaning liquid flows from the interface 353 to the spray head 351 and flows out from the through holes, thereby being fully sprayed to different positions of the tank body 10 and the tank cover 30 on the side facing the accommodating space 20, thereby achieving cleaning of the inside of the tank structure 100.

[0039] In some embodiments, the spray head 351 is a spherical structure with multiple through holes in different directions. The cleaning liquid flows out through the different through holes, thereby evenly spraying the cleaning liquid into the accommodating space 20. In other embodiments, the spray head 351 can also have other shapes, which is not limited by this application.

[0040] The tank body 10 is provided with a stirring module 11, which is disposed at the bottom of the tank body 10 and is used to stir the material contained in the accommodating space 20. The stirring module 11 is electrically connected to the control module 70, which is used to control the operation of the stirring module 11. Specifically, the control module 70 can be used to control the start and stop of the stirring module 11 and the stirring speed.

[0041] In this embodiment, the stirring module 11 includes a stirring wheel 111 and a motor 113. The stirring wheel 111 is located in the accommodating space 20, and the motor 113 is located outside the tank body 10. The stirring wheel 111 and the motor 113 are coaxially arranged, and the motor 113 is used to drive the stirring wheel 111 to rotate, thereby stirring the material in the accommodating space 20. In other embodiments, the stirring module 11 can also be a magnetic stirring structure, that is, a magnetic stirring rod is provided in the accommodating space 20, and a magnetic force generating device is provided outside the tank body 10. The magnetic force generating device is used to generate a magnetic field to drive the magnetic stirring rod to rotate, thereby stirring the material in the accommodating space 20.

[0042] The tank body 10 is further provided with a drain port 13, which is provided at the bottom of the tank body 10 for discharging the material in the accommodating space 20. The drain port 13 may be provided with a valve to control the opening and closing of the drain port 13 to ensure the sealing effect of the tank structure 100.

[0043] The tank body 10 is also provided with a jacket 15, which wraps around the exterior of the tank body 10 and is used to carry hot and cold media to adjust the temperature within the accommodating space 20. Specifically, the jacket 15 includes a media inlet 151 near the bottom of the tank body 10 and a media outlet 153 near the top of the tank body 10. The media enters the jacket 15 through the media inlet 151 and exits through the media outlet 153. The media can be a liquid at a specific temperature. By flowing into the jacket 15, it exchanges heat with the tank body 10, thereby regulating the temperature within the accommodating space 20. By selecting media with different parameters and temperatures, the temperature of the material within the accommodating space 20 can be adjusted.

[0044] The sensing assembly 71 includes a temperature sensor 711, which is used to sense the temperature within the tank structure 100. Specifically, the temperature sensor 711 is disposed at the bottom of the accommodating space 20 and is primarily used to measure the temperature of the material within the accommodating space 20. By disposing the temperature sensor 711 at the bottom of the tank body 10, when the accommodating space 20 is filled with material, the temperature sensor 711 will fully contact the material due to gravity, thereby improving measurement accuracy.

[0045] In some embodiments, the sensing assembly 71 further includes a liquid level sensor 713 , which is disposed on the tank cover 30 and extends toward the bottom of the tank body 10 . The liquid level sensor 713 is used to measure the liquid level of the material in the accommodating space 20 .

[0046] In some embodiments, the sensing assembly 71 further includes a pressure sensor 715, which is disposed on the tank cover 30 and is used to detect the pressure in the accommodating space 20. Specifically, by disposing the pressure sensor 715 on the tank cover 30, it is ensured that the pressure sensor 715 does not contact the material in the accommodating space 20, thereby accurately measuring the air pressure in the accommodating space 20.

[0047] In some embodiments, the control assembly 73 is also electrically connected to the drain port 13, the jacket 15, the feed pipe 31, and the breather 33. Specifically, the control assembly 73 can be used to control the opening and closing of the drain port 13, thereby controlling the discharge of material from the accommodating space 20. The control assembly 73, through its electrical connection to the jacket 15, can be used in conjunction with a temperature sensor 711 to control the temperature of the material within the tank structure 100. The control assembly 73 is electrically connected to the feed pipe 31 to control the entry of material into the accommodating space 20. The control assembly 73 is electrically connected to the breather 33 and can be used in conjunction with a pressure sensor 715 to monitor and adjust the air pressure within the accommodating space 20.

[0048] In some embodiments, the tank structure 100 may further include a mirror and a lighting lamp (not shown), which are used in conjunction with the lighting lamp to observe the condition of the material in the accommodating space 20. In other embodiments, a transparent window may be directly opened on the tank body 10 to directly observe the condition of the material in the accommodating space 20 from the outside, and this application is not limited to this.

[0049] The tank structure 100 provided in the embodiment of the present application can facilitate movement of the tank structure 100 by arranging the tank body 10 to cooperate with the bracket 50 with the moving wheels 51, so that the tank structure 100 can be easily moved when it is used for cross-system transportation. By arranging the tank body 10 and the tank cover 30 to form a closed accommodating space 20, the sealing of the material in the accommodating space 20 can be ensured during the movement of the tank structure 100. By arranging the tank structure 100 to include a control module 70, the parameters of each tank structure 100 can be monitored separately, thereby facilitating confirmation of the status of the material in the tank structure 100. When the tank structure 100 is provided with modules such as a stirring module 11 and a respirator 33, the control module 70 can be directly electrically connected to the corresponding module to control the corresponding module to work. This is conducive to improving the independence of the tank structure 100.

[0050] See also Figure 3 The cleaning system 200 provided in an embodiment of the present application is used to clean the tank structure 100 in the above embodiment, and includes a cleaning module 210 and a reflux module 230. Among them, the cleaning module 210 includes a cleaning pipeline 211, a compressed air pipeline 213 and a steam pipeline 215. The cleaning pipeline 211, the compressed air pipeline 213 and the steam pipeline 215 are connected to the tank structure 100. The reflux module 230 includes a reflux pipeline 231, and the reflux pipeline 231 is connected to the tank structure 100. Optionally, the cleaning system 200 also includes a control cabinet 250, which is electrically connected to the cleaning module 210, the reflux module 230 and the control module 70, and the control cabinet 250 is used to receive the control signal sent by the control module 70.

[0051] Specifically, the cleaning pipeline 211 is connected to the feed pipe 31 and the spray module 35, and a cleaning pump 212 is provided on the cleaning pipeline 211. The cleaning pump 212 is used to pump the cleaning liquid into the tank structure 100 through the cleaning pipeline 211. A valve 220a is also provided on the cleaning pipeline 211. The valve 220a is located between the cleaning pump 212 and the tank structure 100. The valve 220a is used to control the on-off of the cleaning pipeline 211. The valve 220a is connected to the control cabinet 250, and the control cabinet 250 can control the on-off of the valve 220a. The control module 70 can also send a control signal to the control cabinet 250 to control the on-off of the valve 220a. In some embodiments, the control module 70 can also be directly electrically connected to the valve 220a to control the on-off of the valve 220a. This application does not limit this.

[0052] Compressed air line 213 is connected to cleaning line 211 between valve 220a and tank structure 100. Compressed air line 213 is used to pump compressed air into tank structure 100, thereby purging the interior of tank structure 100 and air-drying the inner wall of tank structure 100. A valve 220b is provided on compressed air line 213 to control the opening and closing of compressed air line 213. Valve 220b is electrically connected to control cabinet 250, which can control the opening and closing of valve 220b. Control module 70, which is electrically connected to control cabinet 250, can also control the opening and closing of valve 220b.

[0053] The steam line 215 communicates with the cleaning line 211 between the valve 220a and the tank structure 100. This line is used to pump high-temperature steam into the tank structure 100, thereby heating the tank body 10 and sterilizing the interior of the tank structure 100. A valve 220c is provided on the steam line 215 to control the opening and closing of the steam line 215. The valve 220c is electrically connected to the control cabinet 250, which can control the opening and closing of the valve 220c. The control module 70, which is electrically connected to the control cabinet 250, can also control the opening and closing of the valve 220c.

[0054] In this embodiment, a valve 220e is further provided between the spray module 35 and the cleaning pipeline 211, and a valve 220f is further provided between the feed pipe 31 and the cleaning pipeline 211. The valve 220e is used to control the connection of the cleaning pipeline 211 to the tank structure 100 via the spray module 35, and the valve 220f is used to control the connection of the cleaning pipeline 211 to the tank structure 100 via the feed pipe 31. Specifically, depending on the cleaning process, the cleaning liquid provided by the cleaning pipeline 211 needs to enter the tank structure 100 through the spray module 35 to achieve coverage of the interior of the tank structure 100. The compressed air pumped into the compressed air pipeline 213 also needs to enter the tank structure 100 through the spray module 35 to achieve purging of the interior of the tank structure 100. The high-temperature steam provided by the steam pipeline 215 enters the tank structure 100 through the feed pipe 31, thereby rapidly raising the temperature inside the tank structure 100 for performing the high-temperature sterilization process. In addition, by setting high-temperature steam to enter the tank structure 100 through the feed pipe 31, the feed pipe 31 can also be cleaned with high-temperature steam. In other embodiments, the cleaning liquid can also be controlled to enter the tank structure 100 through the feed pipe 31, and this application does not limit this.

[0055] The return line 231 is connected to the drain port 13 and is equipped with a reflux pump 233 for assisting in pumping out the material within the tank structure 100. A valve 220d is also provided on the return line 231 for controlling the opening and closing of the return line 231. The valve 220d is electrically connected to the control cabinet 250, and the control module 70 can also control the opening and closing of the valve 220d through the control cabinet 250.

[0056] In some embodiments, a conductivity sensor 235 is also provided on the return line 231. The conductivity sensor 235 is located between the return pump 233 and the valve 220d and is used to sense the conductivity of the material in the return line 231. Specifically, the conductivity sensor 235 senses the conductivity of the material to determine the degree of cleaning of the tank structure 100 by the cleaning system 200. When cleaning fluid is released from the cleaning line 211 to clean the tank structure 100, the cleaning fluid and the material form a mixed solution. The conductivity of the mixed solution is related to the ratio of cleaning fluid to material. Therefore, by sensing the conductivity of the mixed solution in the return line 231, it can be determined whether the material in the tank structure 100 has been completely cleaned. The conductivity sensor 235 is electrically connected to the control cabinet 250, thereby enabling the control cabinet 250 to implement an automated cleaning process. In some embodiments, the control module 70 is electrically connected to the conductivity sensor 235 and receives signals from the conductivity sensor 235 to control the cleaning system 200 to implement the automated cleaning process.

[0057] In some embodiments, the control cabinet 250 is an electrical control module for activating pneumatic components, various valves, and the cleaning pump 212 and reflux pump 233. The control module 70 is electrically connected to the control cabinet 250, thereby sending control signals to the various execution units of the control cabinet 250, thereby controlling the operation of the cleaning module 210 and the reflux module 230. In other embodiments, the control module 70 may also be directly electrically connected to the cleaning module 210 and the reflux module 230, and this application is not limited to this.

[0058] In some embodiments, the cleaning process of the cleaning system 200 is specifically as follows:

[0059] Step S1: After the tank structure 100 is connected to the cleaning system 200, valves 220a, 220e and 220d are opened, and the cleaning pump 212 and the reflux pump 233 are started, so that the cleaning liquid is sprayed into the tank structure 100 through the spray module 35 and discharged through the drain port 13. The conductivity sensor 235 is used to detect the conductivity of the mixed liquid in the reflux pipe 231, and when the conductivity reaches the target value, the cleaning pump 212 is turned off.

[0060] Step S2: After the flushing is completed, the valve 220a is closed and the valve 220b is opened, so that compressed air is pumped into the tank structure 100 to purge the interior of the tank structure 100 .

[0061] Step S3: After the purge is completed, close valve 220b and valve 220e, open valve 220c and valve 220f, and introduce steam into the tank structure 100 to heat the tank body 10. After a set time, close valve 220c and open valve 220b to pump compressed air into the tank body 10. After a period of time, close all valves to end the cleaning work.

[0062] The cleaning system 200 provided in this embodiment of the present application, by providing a cleaning line 211, a compressed air line 213, and a steam line 215, can achieve cleaning, drying, and sterilization of the tank structure 100. By providing a control module 70 electrically connected to each valve, various steps in the cleaning process can be adjusted, thereby allowing the user to directly control the cleaning system 200 cleaning the tank structure 100 through the control module 70, thereby improving the convenience of the cleaning process.
