Description

Technical Field

[0001] This application relates to the field of equipment cleaning, and more particularly to a fig cleaning device. Background Technology

[0002] In modern process industries such as biopharmaceuticals and food and beverage, the cleanliness of production equipment (such as fermenters, mixing tanks, and their piping systems) is the cornerstone of ensuring product safety, quality consistency, and compliance. After completing a production batch, these devices retain residual product media, organic contaminants such as proteins, sugars, and lipids, as well as inorganic scale such as minerals and salts. To effectively remove these diverse contaminants, the industry widely employs pre-programmed cleaning systems that automatically clean and disinfect the interior of the equipment without disassembling it.

[0003] Traditional cleaning systems typically consist of a series of centralized cleaning agent tanks, including an alkali tank for removing organic matter, an acid tank for dissolving inorganic scale, and hot water and clean water tanks for rinsing and disinfection. Multiple chemical cleaning media and rinsing water are sequentially pumped into the equipment to be cleaned via the same pipeline. However, this classic "single-channel, multiple-media" model reveals inherent technical limitations in actual operation. During cleaning process switching, such as the transition between an alkaline wash and an acid wash, a large amount of the previous medium (such as alkali) remaining in the shared pipeline inevitably mixes and neutralizes with the subsequently pumped medium (such as acid). This process not only directly leads to a decrease in the effective concentration of the cleaning agent, resulting in unstable cleaning performance and poor reproducibility, but may also cause secondary pollution due to the precipitation of insoluble salts generated by the chemical reaction. Summary of the Invention

[0004] To reduce cross-contamination, this application provides a fig washing device.

[0005] The fig washing device provided in this application adopts the following technical solution: A fig washing device includes a tank, a discharge pipe, a connecting pipe, and a conveying pipe. The tank has a storage chamber, the discharge pipe is connected to the storage chamber, the conveying pipe is located below the discharge pipe, one end of the connecting pipe is connected to the discharge pipe, and the other end of the connecting pipe is connected to the conveying pipe. Multiple tanks are provided and spaced apart along the extension direction of the conveying pipe. One end of the conveying pipe is designated as the inlet end, and the other end is designated as the outlet end. The height of the conveying pipe gradually decreases along the direction from the inlet end to the outlet end.

[0006] By adopting the above technical solution, the discharge pipes of multiple tanks are connected in parallel to a conveying pipe with a specific inclination angle through a connecting pipe. This ensures that the height of the conveying pipe gradually decreases from the inlet end to the outlet end, thus constructing a gravity-driven self-flowing conveying system. This effectively utilizes fluid potential energy and achieves seamless, continuous, and low-energy collection and conveying of materials from multiple tanks to the outlet end. This not only eliminates the need for independent power pumping units for each branch, simplifying the system structure and reducing equipment and maintenance costs, but also significantly improves the reliability and efficiency of the entire conveying process and reduces cross-contamination by avoiding material accumulation in the pipeline and reducing mechanical failure points.

[0007] Preferably, it also includes a first ball valve, through which the discharge pipe is connected to the connecting pipe, and the first ball valve is used to control the connection between the discharge pipe and the connecting pipe.

[0008] By adopting the above technical solutions, operators can flexibly choose to introduce materials from specific tanks into the system for circulation, or isolate them from the system for maintenance, emptying, and other operations, without affecting the normal operation of other tanks. This significantly improves the modularity and operational flexibility of the system, ensuring both the customizability of batch production and the convenience of equipment maintenance, thereby optimizing the efficiency and reliability of the overall process.

[0009] Preferably, it also includes a tilting plate, which is disposed inside the conveying pipe and on the side of the connecting pipe near the feed end. The tilting plate is rotatably connected to the inner wall of the conveying pipe and is used to control the opening and closing of the conveying pipe.

[0010] By adopting the above technical solutions, the reverse flow of materials or pressure transmission is effectively blocked, ensuring that other parts of the conveying pipe will not be disturbed when discharging materials. On the basis of ensuring the independent operation of each tank in the system, the controllability and stability of the entire conveying process are further enhanced, and cross-contamination and pressure disturbance are avoided.

[0011] Preferably, it also includes a transmission component, wherein a rotating column is fixedly connected to the outer wall of the tilting plate, a rotating port is provided on the outer wall of the conveying pipe, the rotating column is coaxially rotatably connected to the inner wall of the rotating port, and the first ball valve is connected to the rotating column through the transmission component.

[0012] By adopting the above technical solution, operators can simultaneously control the opening and closing of the tank outlet and the conveying pipeline with a single action. This not only greatly simplifies the operation process and avoids the possibility of misoperation, but also fundamentally ensures the logical consistency of the opening and closing states of the first ball valve and the tilting plate. When the first ball valve is open, the tilting plate is closed. This not only improves the automation level of the system, but also significantly enhances the accuracy of process control and the overall coordination and reliability of the equipment, enabling timely response and reducing cross-contamination.

[0013] Preferably, it also includes a cleaning pipe, a waste liquid pipe, and a first three-way ball valve. The discharge end of the conveying pipe is connected to the cleaning pipe and the waste liquid pipe through the first three-way ball valve. The first three-way ball valve is used to control the connection and disconnection between the conveying pipe and the cleaning pipe, and between the conveying pipe and the waste liquid pipe.

[0014] By adopting the above technical solution, the system can quickly switch to the cleaning state in the cleaning mode. After the cleaning fluid that needs to be cleaned is quantitatively delivered, the waste liquid is directly introduced into the waste liquid treatment pipeline. This not only significantly improves the equipment utilization rate and fundamentally eliminates cross-contamination, but also greatly reduces the labor costs and hygiene risks caused by disassembling and assembling pipelines in traditional cleaning. It fully meets the management requirements of modern process industries for automation, hygienic design and lean production.

[0015] Preferably, it also includes an air blowing pipe, a disinfection pipe, and a second three-way ball valve. The feed end of the conveying pipe is connected to the air blowing pipe and the disinfection pipe through the second three-way ball valve. The second three-way ball valve is used to control the on / off state of the air blowing pipe and the conveying pipe, as well as the on / off state of the disinfection pipe and the conveying pipe.

[0016] By adopting the above technical solution, compressed gas can be introduced through the air blowing pipe to thoroughly blow away residual liquid in the conveying pipeline. Alternatively, after cleaning, a disinfection medium can be connected through the disinfection pipe for system sterilization, ultimately achieving rapid drying and aseptic preparation of the pipeline. This optimizes the traditional complex disassembly and cleaning process into automated in-situ treatment, which not only greatly improves equipment turnover rate but also effectively eliminates the risk of microbial growth through repeatable standardized cleaning and disinfection procedures, providing a reliable aseptic environment guarantee for continuous batch production.

[0017] Preferably, the plurality of tanks include an alkali tank, an acid tank, a hot water tank, and a clean water tank, arranged sequentially along the feed pipe from the feed end to the discharge end.

[0018] By adopting the above technical solution, the saponification and decomposition of organic dirt by alkaline solution, the dissolution and removal of inorganic scale by acid solution, the sterilization by hot water and the thoroughness of final rinsing are executed in sequence and efficiently. The physical layout fundamentally prevents the mis-order use of cleaning media, and minimizes energy and resource consumption while ensuring the best cleaning effect.

[0019] Preferably, the device further includes an inspection plate and a baffle plate. The outer wall of the feed pipe is provided with an inspection port. The inspection plate is slidably connected to the inner wall of the inspection port. The inspection plate is used for flushing by liquid in the feed pipe. The baffle plate is slidably connected to the outer wall of the feed pipe. The baffle plate is used to cover the inspection port.

[0020] By adopting the above technical solution, the inspection plate is subjected to fluid erosion and chemical action in the same working environment as the medium inside the pipeline for a long time, which can accurately simulate the actual corrosion and aging of the pipe wall. Operators can periodically slide the baffle plate and take out the inspection plate for precise measurement and observation without stopping the machine or damaging the pipeline structure. This enables early warning and trend analysis of pipeline health status, upgrading traditional passive maintenance to proactive preventive maintenance. It can scientifically assess media compatibility, predict pipeline life, and formulate timely replacement strategies. While ensuring the continuous and stable operation of the system, it significantly reduces the safety risks and production losses caused by sudden corrosion leaks.

[0021] Preferably, it further includes a control block, a first magnetic sheet, a second magnetic sheet, and a mounting block. The control block is located on the side of the inspection plate near the feed end. The control block is slidably connected to the inner wall of the conveying pipe. The first magnetic sheet is fixedly connected to the control block. The second magnetic sheet is fixedly connected to the baffle plate. The first magnetic sheet and the second magnetic sheet attract each other. The mounting block is fixedly connected to the control block. The end of the mounting block facing the feed end is provided with a collection trough.

[0022] By adopting the above technical solution, when there is fluid flowing in the conveying pipe, it rushes into the collection trough, pushes the control block to slide, and causes the first magnetic plate to move synchronously. The second magnetic plate is attracted by the first magnetic plate and moves synchronously, causing the baffle plate to move and cover the inspection plate, so that the operator cannot remove the inspection plate, avoiding accidental operation that could cause fluid to rush out from the inspection port, resulting in personal safety losses and resource waste.

[0023] Preferably, it further includes a first spring and a baffle plate. The inner wall of the feed pipe is provided with a sliding groove. A sliding block is fixedly connected to one side of the control block. The sliding block is slidably connected to the groove wall of the sliding groove. One end of the first spring is fixedly connected to the groove wall of the sliding groove away from the feed end. The other end of the first spring is fixedly connected to the sliding block. The baffle plate is fixedly connected to the end of the control block facing the feed end. The baffle plate is used to block the first spring.

[0024] By adopting the above technical solution, when the fluid flows in the conveying pipe, the fluid overcomes the spring tension and pushes the control block to move. When there is no fluid flow in the conveying pipe or the fluid flow rate is extremely low, the spring causes the control block to reset, so that the baffle does not cover the inspection piece, making it easy to remove the inspection piece to check the corrosion in the pipe. The baffle protects the spring by blocking it, reducing the contact between the fluid and the spring, which would otherwise cause the spring to corrode faster.

[0025] In summary, this application includes at least one of the following beneficial technical effects: By connecting the discharge pipes of multiple tanks in parallel to a conveying pipe with a specific inclination angle through a connecting pipe, and ensuring that the height of the conveying pipe gradually decreases from the inlet end to the outlet end, a gravity-driven self-flowing conveying system is constructed. This system effectively utilizes fluid potential energy and achieves seamless, continuous, and low-energy collection and conveying of materials from multiple tanks to the outlet end. It not only eliminates the need for independent power pumping units for each branch, simplifying the system structure and reducing equipment and maintenance costs, but also significantly improves the reliability and efficiency of the entire conveying process and reduces cross-contamination by avoiding material accumulation in the pipeline and reducing mechanical failure points. Operators can simultaneously control the opening and closing of the tank outlet and the conveying pipeline with a single action, which not only greatly simplifies the operation process and avoids the possibility of misoperation, but also fundamentally ensures the logical consistency of the opening and closing states of the first ball valve and the tilting plate. When the first ball valve is open, the tilting plate is closed, thereby improving the automation level of the system, significantly enhancing the accuracy of process control and the overall equipment coordination and reliability, responding in a timely manner, and reducing cross-contamination. The inspection plate is subjected to fluid erosion and chemical action in the same working environment as the medium inside the pipeline for a long time, which can accurately simulate the actual corrosion and aging of the pipe wall. Operators can periodically slide the baffle plate and take out the inspection plate for precise measurement and observation without stopping the machine or damaging the pipeline structure. This enables early warning and trend analysis of pipeline health status, upgrading traditional passive maintenance to proactive preventive maintenance. It can scientifically assess media compatibility, predict pipeline life, and formulate timely replacement strategies. While ensuring the continuous and stable operation of the system, it significantly reduces the safety risks and production losses caused by sudden corrosion leaks. Attached Figure Description

[0031] The following is in conjunction with the appendix Figure 1-4 This application will be described in further detail.

[0032] This application discloses a fig washing device. (Refer to...) Figure 1 A fig cleaning device includes a tank 1, a discharge pipe 2, a conveying pipe 3, a first ball valve 4, a connecting pipe 5, a connecting component 6, an auxiliary component 7, and an inspection component 8.

[0033] Tank 1 is provided with a storage chamber 11, and discharge pipe 2 is connected to the storage chamber 11. Conveying pipe 3 is located below discharge pipe 2. The axis of discharge pipe 2 is horizontal, and the axis of conveying pipe 3 is perpendicular to the axis of discharge pipe 2. Discharge pipe 2 is connected to connecting pipe 5 through first ball valve 4. First ball valve 4 is used to control the connection between discharge pipe 2 and connecting pipe 5. The end of connecting pipe 5 away from first ball valve 4 is connected to conveying pipe 3. The rotation axis of first ball valve 4 is vertical.

[0034] Reference Figure 1 There are four tanks 1, which are evenly spaced along the extension direction of the conveying pipe 3. The multiple tanks 1 include an alkali tank 12, an acid tank 13, a hot water tank 14, and a clean water tank 15. One end of the conveying pipe 3 is designated as the inlet end 31, and the other end is designated as the outlet end 32. The height of the conveying pipe 3 gradually decreases along the direction from the inlet end 31 to the outlet end 32. The clean water tank 15, the hot water tank 14, the acid tank 13, and the alkali tank 12 are arranged sequentially. The inner wall of the conveying pipe 3 is coated with a corrosion-resistant layer.

[0035] There are four discharge pipes 2, which are set one-to-one with the tank body 1. There are eight first ball valves 4 and eight connecting pipes 5, with each discharge pipe 2 corresponding to two connecting pipes 5. There are two conveying pipes 3, which are parallel to each other. Each conveying pipe 3 corresponds to the four discharge pipes 2 on the tank body 1.

[0036] Reference Figure 1 The connecting component 6 includes a first three-way ball valve 61, a cleaning pipe 62, a waste liquid pipe 63, a second three-way ball valve 64, an air blowing pipe 65, and a disinfection pipe 66. The discharge end 32 of the conveying pipe 3 is connected to the cleaning pipe 62 and the waste liquid pipe 63 through the first three-way ball valve 61. The first three-way ball valve 61 is used to control the connection and disconnection between the conveying pipe 3 and the cleaning pipe 62, and between the conveying pipe 3 and the waste liquid pipe 63. Rotating the first three-way ball valve 61 controls three states: no material is discharged from the discharge end 32 of the conveying pipe 3, the conveying pipe 3 is connected to the cleaning pipe 62, and the conveying pipe 3 is connected to the waste liquid pipe 63. The feed end 31 of the conveying pipe 3 is connected to the air blowing pipe 65 and the disinfection pipe 66 via a second three-way ball valve 64. The second three-way ball valve 64 is used to control the connection and disconnection between the air blowing pipe 65 and the conveying pipe 3, and between the disinfection pipe 66 and the conveying pipe 3. Rotating the second three-way ball valve controls three states: no feed at the feed end 31 of the conveying pipe 3, the conveying pipe 3 connected to the air blowing pipe 65, and the conveying pipe 3 connected to the disinfection pipe 66. A flow meter is installed inside the cleaning pipe 62.

[0037] Reference Figure 1 and Figure 2The auxiliary components 7 are provided in eight parts, and each auxiliary component 7 is set in a one-to-one correspondence with the first ball valve 4. The auxiliary components 7 include a tilting plate 71 and a transmission component 72. The tilting plate 71 is located inside the conveying pipe 3 and is located on the side of the connecting pipe 5 near the feed end 31. A rotating column 711 is fixedly connected to the outer wall of the tilting plate 71. A rotating port 36 is provided at the upper end of the conveying pipe 3. The axis of the rotating port 36 is vertical. The rotating column 711 is coaxially rotatably connected to the inner wall of the rotating port 36. The tilting plate 71 is used to control the opening and closing of the conveying pipe 3. The first ball valve 4 is connected to the rotating column 711 via a transmission component 72. The rotation axis of the first ball valve 4 and the axis of the rotating column 711 are collinear. The transmission component 72 consists of a first transmission rod 721, a first spring 722, and a second transmission rod 723. One end of the first transmission rod 721 is fixedly connected to the ball core of the first ball valve 4, and the other end of the first transmission rod 721 is provided with a limiting groove 7211, which is rectangular. One end of the second transmission rod 723 is slidably connected to the limiting groove 7211. The groove wall of the first transmission rod 723 is provided with a groove 7231 at the other end of the second transmission rod 723. The groove wall of the groove 7231 is provided with a positioning groove 7232. The outer wall of the rotating column 711 is fixedly connected with a positioning strip 7111. The groove 7231 is used for the rotating column 711 to slide into the groove, and the positioning groove 7232 is used for the positioning strip 7111 to slide into the groove. One end of the first spring 722 is fixedly connected to the bottom of the limiting groove 7211, and the other end of the first spring 722 is fixedly connected to the second transmission rod 723.

[0038] Reference Figure 2 and Figure 3 The inspection assembly 8 includes an inspection plate 81, an anti-detachment plate 82, a blocking plate 83, a control block 84, a second spring 85, a first magnetic plate 86, a second magnetic plate 87, a mounting block 88, and a shielding plate 89. There are eight inspection assemblies 8, and each inspection assembly 8 is arranged in a one-to-one correspondence with the connecting pipe 5.

[0039] Reference Figure 1 and Figure 4 The upper end of the conveying pipe 3 is provided with an inspection groove 33, and the bottom of the inspection groove 33 is provided with an inspection port 34. The inspection port 34 is located on the side of the connecting pipe 5 near the discharge end 32.

[0040] Reference Figure 3 and Figure 4The inspection plate 81 is slidably connected to the inner wall of the inspection port 34. The inspection plate 81 extends into the feed pipe 3 for flushing by the liquid inside the feed pipe 3. The anti-detachment plate 82 is fixedly connected to the upper end of the inspection plate 81. The anti-detachment plate 82 is used to embed into the inspection groove 33. When the anti-detachment plate 82 is embedded in the inspection groove 33, the upper end surface of the anti-detachment plate 82 is coplanar with the outer wall of the feed pipe 3. The pull ring is fixedly connected to the upper end of the anti-detachment plate 82 and is used for operator hand contact. The blocking plate 83 is slidably connected to the upper end of the feed pipe 3. The blocking plate 83 is used to prevent the anti-detachment plate 82 from moving upward. The lower end surface of the blocking plate 83 is in contact with the outer wall of the feed pipe 3. The pull ring is located on one side of the blocking plate 83 and does not interfere with the blocking plate 83.

[0041] Reference Figure 2 and Figure 4 The control block 84 is located between the connecting pipe 5 and the inspection plate 81, and the control block 84 is slidably connected to the lower inner wall of the conveying pipe 3.

[0042] Reference Figure 3 and Figure 4 The control block 84 has a clearance groove 841 at one end facing the inspection piece 81, which is used to avoid the inspection piece 81. A sliding block 842 is fixedly connected to the upper end of the control block 84. A sliding groove 35 is provided on the lower inner wall of the feed pipe 3. The length direction of the sliding groove 35 is parallel to the axis of the feed pipe 3. There are two sliding grooves 35, which are respectively located on both sides of the inspection piece 81. There are two sliding blocks 842, which are arranged one-to-one with the sliding grooves 35. The sliding blocks 842 are slidably embedded in the sliding grooves 35. The sliding grooves 35 are designed as dovetail grooves, and the sliding blocks 842 are designed as dovetail blocks. One end of the second spring 85 is fixedly connected to the groove wall of the sliding groove 35 away from the feed end 31, and the other end of the second spring 85 is fixedly connected to the sliding block 842.

[0043] Reference Figure 1 and Figure 3 The first magnetic sheet 86 is fixedly connected to the sliding block 842, and the second magnetic sheet 87 is fixedly connected to the baffle plate 83. The first magnetic sheet 86 and the second magnetic sheet 87 attract each other. The mounting block 88 is fixedly connected to the lower end of the control block 84. There are two mounting blocks 88, which are located on both sides of the clearance groove 841. The end of the mounting block 88 facing the feed end 31 is provided with a collection groove 881 for water flow impact, so that the water flow can drive the control block 84 to move. The height of the groove wall facing upward of the collection groove 881 decreases as it moves away from the bottom of the collection groove 881, which facilitates liquid drainage.

[0044] Reference Figure 1 and Figure 2 The baffle plate 89 is fixedly connected to the end of the control block 84 facing the feed end 31. The baffle plate 89 slides against the inner wall of the feed pipe 3. The baffle plate 89 is used to block the second spring 85.

[0045] Reference Figure 2 and Figure 3 The water flow impacts the inspection piece 81, which is used to check the corrosion of the inner wall of the pipe. When there is water flow in the conveying pipe 3, the water flow impacts the mounting block 88, causing the control block 84 to slide against the tension of the second spring 85. The inspection piece 81 slides into the relief groove 841. At the same time, the control block 84 slides, and the first magnetic piece 86 and the second magnetic piece 87 drive the blocking plate 83 to slide, so that the blocking plate 83 obstructs the upward movement of the anti-detachment plate 82, making it impossible for the operator to remove the inspection piece 81 when the water flow is flowing. When the water flow stops, the second spring 85 causes the control block 84 to reset, and the blocking plate 83 no longer obstructs the movement of the anti-detachment plate 82. When it is necessary to check the corrosion of the inner wall of the pipe, the anti-detachment plate 82 and the inspection piece 81 can be removed by pulling the ring. Water flows inside the feed pipe 3, which pushes the control block 84 to move. Since there is no obstruction from the inspection plate 81, the control block 84 can move a longer distance. The control block 84 and the baffle plate 89 together cover the inspection port 34, making it difficult for liquid to rush out of the inspection port 34, protecting the operator and reducing resource waste. When the inspection port 34 is opened, the inspection plate 81 is reinstalled. If the inner wall of the pipe is corroded, it means that the corrosion-resistant layer of the inner wall of the pipe has been damaged. The second transmission rod 723 is moved away from the rotating column 711, and the flip plate 71 is rotated to block the corroded pipe section. The spray gun is inserted through the inspection port 34 to spray and repair the inner corrosion layer, or a chemical solution that can form a protective film on the metal surface is injected to achieve pipe repair.

[0046] The implementation principle of the fig cleaning device in this application embodiment is as follows: Solutions from the alkali tank 12, acid tank 13, hot water tank 14, and clean water tank 15 are sequentially discharged to clean the device. Taking the discharge from the alkali tank 12 as an example, the first ball valve 4 is opened, the tilting plate 71 is closed, and the first three-way ball valve 61 rotates to connect the conveying pipe 3 with the cleaning pipe 62. The alkali solution passes sequentially through the discharge pipe 2, the connecting pipe 5, and the conveying pipe 3 before being discharged from the cleaning pipe 62. A flow meter is installed on the cleaning pipe 62 to detect the volume of alkali solution discharged. When enough solution is discharged… After the alkali solution is removed, the first ball valve 4 is closed, and the first three-way ball valve 61 is rotated to connect the feed pipe 3 with the waste liquid pipe 63. The flip plate 71 is opened, and the second three-way ball valve 64 is rotated to connect the feed pipe 3 with the air blowing pipe 65, thereby emptying the excess alkali solution in the feed pipe 3. The alkali solution moves along the height difference of the feed pipe 3, reducing the amount of alkali solution in the feed pipe 3. Protective gas is blown into the feed pipe 3 to reduce the adhesion of alkali solution in the feed pipe 3 and minimize cross-contamination. Then, the operation is repeated for the acid tank 13, the hot water tank 14, and the clean water tank 15.

[0047] 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.
