[0033] To address the problem of low testing efficiency of existing tank washing machines, this application provides a testing device.

[0034] like Figure 1As shown, the testing device includes a liquid infusion structure 10, a pressurization structure 20, and a protective structure 30. The liquid infusion structure 10 has an inlet section 11, a liquid infusion chamber, and an outlet section 12. The inlet section 11 communicates with the outlet section 12 through the liquid infusion chamber. The inlet section 11 is used to communicate with external equipment. The liquid infusion chamber is used to contain liquid. The outlet section 12 is used to communicate with the cleaning component 1. The liquid infusion structure 10 includes multiple pipes arranged sequentially along the liquid flow direction. The pressurization structure 20 is disposed between two adjacent pipes to pressurize the liquid. The protective structure 30 is disposed on the outlet section 12 and has a protective cavity 31 for containing the cleaning component 1. The cleaning holes of the cleaning component 1 are used to clean the protective cavity 31. At least a portion of the protective structure 30 is made of transparent material and is disposed opposite to the cleaning component 1.

[0035] Applying the technical solution of this embodiment, the infusion structure 10 of the testing device has an inlet section 11, an infusion chamber, and an outlet section 12. The inlet section 11 is connected to the outlet section 12 through the infusion chamber. The inlet section 11 is used to communicate with external equipment, the infusion chamber is used to contain liquid, and the outlet section 12 is used to communicate with the cleaning component 1. The infusion structure 10 includes multiple pipes, which are arranged sequentially along the liquid flow direction. A pressurization structure 20 is disposed between two adjacent pipes to pressurize the liquid. A protective structure 30 is disposed on the outlet section 12. The protective structure 30 has a protective cavity 31, which is used to contain the cleaning component 1. The cleaning hole of the cleaning component 1 is used to clean the protective cavity 31. At least a portion of the protective structure 30 is made of transparent material and is disposed opposite to the cleaning component 1. In this way, after the staff disassembles the tank washer from the fermenter for maintenance and upkeep, they connect the maintained tank washer to the outlet section 12 and the inlet section 11 to external equipment. The external equipment is then activated to deliver liquid through the delivery chamber to the outlet section 12 and spray it out from the cleaning hole of the tank washer to clean the protective cavity 31 of the protective structure 30, simulating the working state and cleaning process of the tank washer in the fermenter. Simultaneously, the pressurization structure 20 pressurizes the liquid, simulating the working water pressure of the tank washer in the fermenter, ensuring the consistency between the test conditions of the testing device and the working conditions inside the fermenter, thus guaranteeing the accuracy and reliability of the test device. Furthermore, the arrangement of the protective structure 30 allows it to simulate the fermenter, improving the compatibility between the testing device and the fermenter; it also allows staff to observe and monitor the operating status of the tank washer through the protective structure 30, ensuring the reliability of the tank washer's operation, preventing malfunctions when the tank washer is installed inside the fermenter, and improving the testing efficiency of the maintained tank washer, thereby solving the problem of low testing efficiency of tank washer in existing technologies. Meanwhile, the way the protective structure 30 is set also controls the spray range of the liquid, thus achieving the cleanliness of the test environment.

[0036] In this embodiment, the cleaning component 1 is a tank cleaner.

[0037] In this embodiment, the booster structure 20 is a booster pump.

[0038] In this embodiment, the pressurization structure 20 increases the pressure of the liquid in the range of 4 bar to 6 bar.

[0039] In this embodiment, the liquid is either water or a cleaning solution.

[0040] In this embodiment, the nominal diameter of the pipe is 65mm.

[0041] like Figure 1 As shown, the protective structure 30 also has a liquid outlet that communicates with the protective cavity 31 to discharge the liquid inside the protective cavity 31. This communication between the liquid outlet and the protective cavity 31 allows the liquid inside to be discharged, facilitating liquid recycling, reducing production costs, improving the economic efficiency of the testing device, and preventing liquid from accumulating in the protective cavity 31 and affecting the normal operation of other equipment, thus ensuring the reliability and safety of the testing device.

[0042] In this embodiment, the infusion structure 10 also includes an outlet pipe. At least a portion of the outlet pipe extends along a predetermined direction. The protective structure 30 is fixedly connected to the outlet pipe and covers at least a portion of the outlet pipe. The bottom of the protective structure 30 is hollowed out to form a flow port. An outlet section 12 is formed at the end of the outlet pipe, and a detachable component is provided on the outlet section 12 for detachable engagement with the cleaning component 1. Thus, the extension of at least a portion of the outlet pipe along the predetermined direction ensures the suitability of the tank washer installation position and optimizes the installation space of the protective structure 30 and the tank washer. Simultaneously, the outlet pipe provides stable support for the protective structure 30, ensuring the installation reliability and structural stability of the protective structure 30. Furthermore, the hollowed-out bottom of the protective structure 30 forms a flow port, simplifying the formation of the flow port, facilitating worker processing, and improving worker efficiency.

[0043] like Figure 1 As shown, the preset direction is set perpendicular to the horizontal plane, so that the extension direction of the protective structure 30 is also set perpendicular to the horizontal plane. In this way, the above-mentioned arrangement optimizes the installation space of the protective structure 30, ensuring the ease of installation; on the other hand, it allows the liquid inside the protective structure 30 to flow out from the protective cavity 31 under the action of gravity, avoiding the retention of liquid in the protective cavity 31 and improving the operational reliability of the protective structure 30.

[0044] like Figure 1As shown, the protective structure 30 includes a protective end plate 32 and a protective side plate 33 connected to each other. The protective side plate 33 is arranged along the periphery of the protective end plate 32, and the end of the protective side plate 33 away from the protective end plate 32 forms a liquid outlet. Both the protective end plate 32 and the protective side plate 33 are made of transparent material. The liquid outlet 12 has a preset distance from both the protective end plate 32 and the protective side plate 33. This arrangement makes the protective structure 30 cylindrical, simplifying the formation of the protective cavity 31 and the liquid outlet, and improving the processing efficiency of the workers. Simultaneously, the transparent design of the protective end plate 32 and the protective side plate 33 allows workers to observe the operating status of the tank washer from multiple directions and angles, improving the comprehensiveness and accuracy of the testing device. Furthermore, the preset distance between the liquid outlet 12 and the protective end plate 32 and the protective side plate 33 prevents the tank washer from colliding with the protective structure 30 during operation, ensuring the safety and smooth operation of the tank washer, and thus guaranteeing the testing reliability of the testing device.

[0045] In this embodiment, the protective end plate 32 is fitted onto the liquid outlet pipe.

[0046] In this embodiment, the diameter D of the liquid outlet satisfies: 480mm ≤ D ≤ 520mm; and / or, the height H of the protective structure 30 satisfies: 480mm ≤ H ≤ 520mm. This arrangement, on the one hand, makes the size of the liquid outlet more suitable, resulting in a more appropriate flow rate and velocity of the liquid flowing out of the outlet under gravity, ensuring smooth liquid flow; on the other hand, it makes the height of the protective structure 30 more suitable, ensuring both normal cleaning of the protective chamber 31 by the tank washer and the structural stability of the protective structure 30. It also ensures that personnel can observe the operating status of the tank washer without obstruction, guaranteeing the testing stability and reliability of the testing device.

[0047] In this embodiment, the diameter D of the liquid outlet satisfies: D = 500 mm, to ensure that the value of the diameter D of the liquid outlet is more appropriate.

[0048] In this embodiment, the height H of the protective structure 30 satisfies: H = 500mm, to ensure that the value of the height H of the protective structure 30 is more appropriate.

[0049] like Figure 1As shown, the testing device also includes a first detection structure 40. The first detection structure 40 is disposed on the pipeline of the infusion structure 10 located between the pressurization structure 20 and the outlet section 12. The detection end of the first detection structure 40 extends into the infusion chamber to detect the pressure of the liquid within the infusion chamber. And / or, the testing device also includes a second control valve 60, which is disposed on the pipeline of the infusion structure 10 located between the pressurization structure 20 and the outlet section 12. The second control valve 60 is connected to the first detection structure 40 to control the flow rate and / or flow volume of the liquid within the infusion chamber based on the detection result of the first detection structure 40. In this way, the first detection structure 40 can detect the pressure of the liquid in the pipeline between the pressurization structure 20 and the outlet section 12 in real time, correspondingly detecting the pressurization effect of the pressurization structure 20. This ensures that the liquid in the infusion chamber meets the pressurization standard after pressurization, adapting to the requirements of different specifications and sizes of tank washers, improving the testing versatility of the testing device, and also ensuring the testing reliability of the testing device. Meanwhile, the configuration of the second control valve 60 ensures the adjustability of the liquid input pressure, guaranteeing the accuracy of the test; on the other hand, it can react promptly when abnormal pressure is detected, avoiding damage to the testing device due to excessively high or low pressure, extending the service life of the testing device, and protecting the safety of the staff.

[0050] In this embodiment, the first detection structure 40 is a pipeline pressure sensor.

[0051] In this embodiment, the second control valve 60 is a control valve.

[0052] In this embodiment, the flow rate of the liquid in the infusion chamber is controlled at 14m³. 3 / h to 18m 3 Within the range of / h.

[0053] Specifically, the flow rate of the fluid in the infusion chamber is 16m³. 3 / h.

[0054] like Figure 1As shown, the testing device also includes a first control valve 50 and a second detection structure. The first control valve 50 is installed on the pipeline of the infusion structure 10 between the inlet section 11 and the pressurization structure 20, and is used to control the flow rate and / or flow volume of the liquid in the infusion chamber. The second detection structure is installed on the pipeline of the infusion structure 10 between the pressurization structure 20 and the outlet section 12, and its detection end extends into the infusion chamber to detect the flow rate of the liquid in the infusion chamber. In this way, the first control valve 50 can control the initial flow rate and flow volume of the liquid, allowing operators to pre-set the flow conditions of the liquid, reducing subsequent debugging time and effort, and ensuring the ease and speed of operation of the testing device. This design not only simplifies the preparation work before testing, but also effectively avoids test result deviations caused by unstable fluid parameters, significantly improving the overall testing efficiency of the system and the testing efficiency of the testing device. At the same time, the second detection structure can detect the flow rate of the liquid after pressurization by the pressurization structure 20 in real time, forming a complementary dual detection mechanism with the first detection structure 40, and constructing a closed-loop control system. This system can instantly compare flow data before and after pressurization, ensuring that the liquid flow rate remains within the ideal range and greatly enhancing the accuracy of input liquid parameters. Through the synergistic effect of the first detection structure 40 and the second detection structure, the testing device can more precisely adjust and control the testing conditions, further improving the accuracy and reliability of the test results.

[0055] In this embodiment, the second detection structure is a liquid flow sensor.

[0056] In this embodiment, the first control valve 50 is a control valve.

[0057] like Figure 1 As shown, the testing apparatus also includes a recovery structure 70. The recovery structure 70 is positioned below the protective structure 30 and has a recovery tank 71 for accommodating liquid discharged from the outlet. The orthographic projection of the protective structure 30 onto the recovery tank 71 lies within the tank. This ensures that liquid flowing from the protective cavity 31 through the outlet accurately falls into the recovery tank 71 of the recovery structure 70. This design guarantees effective liquid recovery, achieving not only liquid recycling and significantly improving the economic and environmental performance of the testing apparatus, but also demonstrating efficient resource management. Simultaneously, the ingenious design of the recovery tank 71 maximizes liquid capture and collection, effectively preventing liquid splashing outside the tank. This measure greatly reduces potential pollution to the external environment and enhances the reliability of the recovery effect of the recovery structure 70. Furthermore, by optimizing the design of the recovery tank 71, we can significantly improve the cleanliness of the working environment, providing operators with safer and healthier working conditions, further demonstrating that the testing apparatus improves work efficiency while ensuring environmental safety.

[0058] In this embodiment, the recycling structure 70 also has a support leg, which is located at one end of the recycling tank 71 near the working base surface to support the recycling tank 71 and also to keep the recycling tank 71 at a certain distance from the working base surface, so as to avoid impurities on the working base surface from damaging the recycling tank 71 and extending the service life of the recycling tank 71.

[0059] In this embodiment, the testing device also includes a camera structure. The camera structure is located on the side of the protective side plate 33 away from the protective cavity 31, and is positioned facing the protective cavity 31 to capture the operating status of the cleaning component 1. This configuration allows for real-time recording of the washing tank's operating status, providing testers with intuitive video evidence for subsequent review and analysis, thus enhancing the intelligence of the testing device. Simultaneously, the camera structure can be connected to a remote monitoring system, enabling remote monitoring. Operators do not need to be physically present on-site to monitor the testing situation in real time via video signals, reducing the risks of working in high temperatures and confined spaces, lowering the workload of staff, and improving work efficiency.

[0060] like Figure 1 As shown, the testing device also includes a drainage structure 80 and a third control valve 90. The drainage structure 80 has an inlet, a drainage chamber, and a drainage outlet. The inlet is connected to the drainage chamber and the drainage outlet, and the inlet is connected to the recovery tank 71. The drainage chamber is used to contain the liquid in the recovery tank 71, and the drainage outlet is used to discharge the liquid from the drainage chamber. The third control valve 90 is installed on the drainage structure 80 to control the flow rate and / or flow volume of the liquid in the drainage chamber. This arrangement of the drainage structure 80 allows the liquid in the recovery tank 71 to be discharged through the inlet and the drainage outlet, preventing excessive liquid accumulation in the recovery tank 71 and thus ensuring liquid circulation. Simultaneously, the third control valve 90 allows for precise control of the flow rate and flow volume of the liquid in the drainage chamber, enabling flexible adjustment of the operating state of the drainage structure 80 and improving its drainage flexibility.

[0061] In this embodiment, the testing device also includes a control device, which is connected to the first detection structure 40, the second detection structure, the first control valve 50, the second control valve 60, the third control valve 90, and the camera structure. This configuration forms a highly integrated control system, allowing the testing device to automatically adjust the state of each valve and precisely control the water pressure and flow rate, ensuring that the tank washer's operating parameters meet preset standards during testing. Simultaneously, the control device, combined with data feedback from the first and second detection structures, can instantly analyze and evaluate the cleaning effect and performance status of the tank washer, significantly improving the accuracy and efficiency of the test. Furthermore, this configuration not only automates and visualizes the testing process but also greatly enhances the safety, reliability, and convenience of the test, thereby significantly improving the overall system's operational efficiency and management level.

[0062] As can be seen from the above description, the embodiments of this utility model achieve the following technical effects:

[0063] The test device's liquid delivery structure includes an inlet section, a delivery chamber, and an outlet section. The inlet section connects to the outlet section via the delivery chamber and is used to communicate with external equipment. The delivery chamber contains liquid, and the outlet section connects to the cleaning component. The liquid delivery structure includes multiple pipes arranged sequentially along the liquid flow direction. A pressurization structure is located between adjacent pipes to pressurize the liquid. A protective structure is located on the outlet section and has a protective cavity for containing the cleaning component. A cleaning port on the cleaning component is used to clean the protective cavity. At least a portion of the protective structure is made of transparent material and is positioned opposite the cleaning component. Thus, after the tank washer is disassembled from the fermenter for maintenance, the worker connects the maintained tank washer to the outlet section and the inlet section to the external equipment. The external equipment is then activated to deliver liquid through the delivery chamber to the outlet section and spray it out from the cleaning port of the tank washer to clean the protective cavity of the protective structure, simulating the working state and cleaning process of the tank washer in the fermenter. Meanwhile, the pressurization structure, by pressurizing the liquid, simulates the working water pressure of the tank washer in the fermenter, ensuring the consistency of the test conditions between the testing device and the working conditions inside the fermenter, thus guaranteeing the accuracy and reliability of the test device. Simultaneously, the protective structure's design, on the one hand, allows the protective structure to simulate the fermenter, improving the compatibility between the testing device and the fermenter; on the other hand, it allows personnel to observe and monitor the tank washer's operating status through the protective structure, ensuring the tank washer's operational reliability, preventing malfunctions when the tank washer is installed inside the fermenter, and improving the testing efficiency of the tank washer after maintenance, thereby solving the problem of low testing efficiency in existing tank washer technologies. Furthermore, the protective structure's design also controls the liquid spray range, ensuring a clean testing environment.
