Description

Technical Field

[0001] This utility model relates to the field of automatic cleaning technology, specifically to an online automatic cleaning device. Background Technology

[0002] In the pharmaceutical industry, pipelines play an indispensable role in the production process as key equipment for transporting various chemicals, gases, and other materials. However, during use, pipelines often accumulate residual chemicals, impurities, and sediments. These residues can not only cause blockages, affecting the normal transport of materials, but also corrode the pipelines, shortening their lifespan. More importantly, contaminants within the pipelines can pollute the pharmaceutical production environment, seriously affecting product quality and jeopardizing the safety and efficacy of the drugs. Therefore, regular pipeline cleaning is a necessary measure to ensure product quality and production safety in pharmaceutical manufacturing.

[0003] Currently, the main technologies for cleaning air intake and exhaust ducts involve manual cleaning with tools or no cleaning at all. Manual cleaning has several drawbacks. For example, it's difficult to completely remove material residues from the ducts, leading to long-term material accumulation and potential microbial contamination of the product. Furthermore, manual cleaning is inefficient and struggles to ensure uniformity and consistency. Conversely, neglecting cleaning allows dust to accumulate in the ducts, posing a safety hazard to the equipment. Changes in the accumulated material may also introduce foreign matter, potentially threatening product quality and severely impacting the safety and stability of pharmaceutical production. Utility Model Content

[0004] The purpose of this invention is to provide an online automatic cleaning device. This device uses spray cleaning balls distributed on the air inlet and outlet ducts. The cleaning medium can be sprayed into the duct at different angles and speeds through the spray balls, thereby covering more of the inner surface of the duct and solving the problems of incomplete cleaning and blind spots in traditional manual cleaning. At the same time, by pressurizing the cleaning process and introducing compressed air to blow it out, combined with a drying component, a closed-loop process of "cleaning-blowing-drying" is formed, which solves the problems of residual water causing microbial contamination and the inefficiency of manual cleaning.

[0005] This utility model is achieved through the following technical solution:

[0006] An online automatic cleaning device includes:

[0007] A cleaning assembly includes multiple spray cleaning balls, which are distributed along the length of the air inlet and exhaust duct. The spray cleaning balls spray cleaning medium around the inner wall of the air inlet and exhaust duct. After the inner wall of the air inlet and exhaust duct is washed by the cleaning medium, the cleaning assembly introduces compressed gas into the air inlet and exhaust duct to remove the residual medium on the inner wall of the air inlet and exhaust duct.

[0008] The drying component is connected to the air inlet and exhaust ducts, so that the air inlet and exhaust ducts form a closed-loop cleaning path of "cleaning medium spraying - residual water purging - drying".

[0009] In this solution, the distributed spray cleaning balls in the cleaning assembly can spray cleaning medium around the inner wall along the length of the pipe, achieving circumferential coverage of the inner wall without dead angles. This solves the problems of blind spots and difficulty in thoroughly removing residual materials in traditional manual cleaning. After the cleaning medium flushes the pipe, compressed gas is introduced to remove the residual medium. Combined with the drying assembly, the inlet and outlet air ducts are connected to form a closed-loop cleaning path of "cleaning medium spraying - residual water purging - drying". The entire process from cleaning to drying can be completed online without disassembling the pipe. This not only avoids the risk of microbial contamination caused by residual water, but also improves cleaning efficiency through integrated design, ensuring that the inner wall of the pipe quickly reaches a dry and clean state after cleaning. This effectively solves the problems of inefficiency, incompleteness, and improper residual water treatment in existing technologies.

[0010] As a further embodiment of the cleaning device, the surface of the spray cleaning ball is evenly distributed with spray holes of 3mm-5mm diameter, and is driven to rotate by the reaction force of the cleaning medium to cover a circumferential 180°-360° area of ​​the inner wall of the air inlet and outlet duct.

[0011] In this design, evenly distributed spray holes with a diameter of 3mm-5mm allow the cleaning medium to be ejected from the holes at appropriate pressure and flow rate. This ensures sufficient impact force on the inner wall of the air inlet and outlet ducts, effectively flushing away various impurities and contaminants adhering to the inner wall. Simultaneously, the reaction force of the cleaning medium drives the spray cleaning balls to rotate, enabling them to cover a 180°-360° circumferential area of ​​the inner wall of the air inlet and outlet ducts. This avoids cleaning dead zones and achieves comprehensive and thorough cleaning of the duct inner wall.

[0012] As a further embodiment of the cleaning device, the drying assembly includes an exhaust device, a drying device, and an air inlet device connected in sequence, and the air inlet device provides clean and dry air to the drying device, and the clean and dry air is discharged from the exhaust device after circulating through the air inlet and exhaust pipes.

[0013] In this solution, a complete air circulation and drying system is constructed by setting up an exhaust device, a drying device, and an air intake device connected in sequence. The clean, dry air provided by the air intake device prevents impurities and moisture from re-contaminating the intake and exhaust ducts, ensuring a pure drying environment. The clean, dry air circulates within the intake and exhaust ducts, efficiently removing residual moisture after cleaning, achieving rapid drying, and preventing problems such as rusting of ducts and microbial growth caused by residual moisture. Finally, the humid air is discharged through the exhaust device, maintaining the dryness of the air within the system.

[0014] As a further embodiment of the cleaning device, the cleaning device also includes a drainage system, which includes a drain valve located at the lowest point of the pipe and at the bottom of the drying equipment, through which the cleaning medium after rinsing is discharged.

[0015] In this solution, the drainage system places the drain valve at the lowest point of the pipeline, using gravity to allow the cleaning medium (including sewage, residual liquid, etc.) after rinsing to naturally collect and discharge, avoiding residual water retention caused by the difference in pipeline height; at the same time, a drain valve is installed at the bottom of the drying equipment to promptly discharge any condensate or residual liquid that may be generated during the drying process, ensuring that there is no liquid residue in the entire cleaning and drying process.

[0016] As a further embodiment of the cleaning device, the front of the drying equipment is provided with an observation window for visually inspecting the drying status of the inner wall of the pipe.

[0017] In this solution, the observation window allows operators to visually inspect the inner walls of the inlet and outlet ducts for residual moisture, stains, or areas that have not been thoroughly cleaned after the cleaning and drying process is completed, without disassembling the ducts or drying equipment, ensuring that the ducts are dry in a manner that meets production requirements.

[0018] As a further embodiment of the cleaning device, the air intake device includes a second filter, an air intake heating device, and an air intake fan. The air intake fan, the air intake heating device, and the filter are connected in sequence to provide clean and dry air to the drying equipment.

[0019] In this solution, the filter effectively traps dust, particles, and other impurities in the air, preventing secondary pollution of clean, dry air during its generation and ensuring that the air entering the drying equipment meets the cleanliness standards required by the pharmaceutical industry. The air intake heating device reduces the humidity of the air by heating it, providing the drying equipment with a high-efficiency moisture-absorbing dry air source and accelerating the evaporation of residual moisture on the inner walls of the air intake and exhaust ducts. The air intake fan provides power for airflow, enabling clean, dry air to continuously and stably enter the air intake and exhaust ducts through the drying equipment, forming a circulating dry airflow. This not only provides the required air source conditions for the drying process, ensuring that residual moisture on the inner walls of the ducts is quickly carried away, but also eliminates the risk of external pollutants entering the ducts with the air, effectively avoiding problems such as duct corrosion and microbial growth caused by moisture or impurities.

[0020] As a further embodiment of the cleaning device, the drain valve includes a first drain valve and a second drain valve, wherein the first drain valve is located at the lowest horizontal section of the air inlet and outlet duct, the second drain valve is located at the end of the air outlet duct, and the bottom of the drying equipment has a built-in drain outlet, forming a multi-point low-level drainage structure.

[0021] In this solution, the first drain valve is located at the lowest horizontal section of the pipeline. Utilizing gravity, the wastewater and residual liquid washed away during the cleaning process naturally collect and are quickly discharged, preventing water accumulation blind spots due to elevation differences in the horizontal section. The second drain valve is located at the end of the exhaust duct, promptly removing residual water flowing along the pipeline to the end, preventing microbial growth or impurity deposition caused by liquid accumulation. The drain outlet at the bottom of the drying equipment simultaneously discharges condensate or residual liquid generated during the drying process, ensuring zero water retention in the drying stage. This multi-point low-level drainage structure, through "segmented diversion + end control + equipment linkage," forms a three-dimensional drainage network for residual media within the pipeline, fundamentally solving the problem of residual water caused by incomplete drainage in traditional cleaning methods, effectively reducing the risk of pipeline corrosion and microbial contamination.

[0022] As a further embodiment of the cleaning device, the cleaning assembly includes a water storage tank and a fluid pipeline, wherein the water storage tank provides the cleaning medium or compressed gas to the spray cleaning ball through the fluid pipeline.

[0023] In this solution, the water storage tank serves as a storage container for the cleaning medium and compressed gas, ensuring a stable and continuous supply of the required substances during the cleaning process and preventing cleaning interruptions due to medium or gas shortages. The fluid pipeline acts as a bridge connecting the water storage tank and the spray cleaning ball, delivering the cleaning medium from the water storage tank to the spray cleaning ball at appropriate pressure and flow rate. This allows the spray cleaning ball to spray the cleaning medium to effectively flush the inner walls of the inlet and outlet ducts. After cleaning, the compressed gas from the water storage tank is delivered to the spray cleaning ball, using the compressed gas to remove residual medium from the inner walls of the ducts, achieving a continuous cleaning and purging operation.

[0024] As a further embodiment of the cleaning device, the cleaning assembly also includes a compressor pump, an air inlet is provided at the top of the water storage tank for receiving the compressed gas, the bottom of the water storage tank is fixed by a base, and the compressor pump pressurizes the cleaning medium in the water storage tank and then transports it to the spray cleaning ball through the fluid pipeline.

[0025] In this solution, a compressor pump pressurizes the cleaning medium in the water storage tank, giving it strong pressure energy. When transported to the spray cleaning balls through fluid pipelines, it is ejected at high speed and high pressure, enhancing the flushing force on impurities on the inner walls of the air inlet and outlet ducts, resulting in a more thorough cleaning. The air inlet at the top of the water storage tank is used to connect compressed gas, providing an air source for purging residual media after cleaning, thus realizing an integrated cleaning and purging process.

[0026] As a further embodiment of the cleaning device, the cleaning device also includes a control system, which is electrically connected to the cleaning component and the drying component respectively.

[0027] In this solution, the control system can coordinate the working sequence and time interval between the cleaning and drying components, achieving a seamless transition from cleaning to drying, avoiding resource waste, and improving cleaning efficiency.

[0028] Compared with the prior art, this utility model has the following advantages and beneficial effects:

[0029] 1. This utility model uses multiple spray cleaning balls arranged in a distributed manner along the length of the air inlet and outlet ducts. The cleaning medium can be sprayed into the duct at different angles and speeds through the spray balls, thereby covering more of the inner surface of the duct and solving the problems of incomplete cleaning and blind spots in traditional manual cleaning.

[0030] 2. This utility model forms a closed-loop cleaning path of "cleaning medium spraying - residual water purging - drying" on the air inlet and outlet ducts. After cleaning, compressed gas is introduced to remove the residual medium. Combined with the multi-point low-level drainage structure located at the lowest point of the duct and the bottom of the drying equipment, residual water can be discharged in time, avoiding the risk of microbial contamination caused by residual water. Moreover, the entire cleaning process can be completed online without disassembling the duct. Compared with the traditional manual cleaning method, it greatly improves the cleaning efficiency and saves time and labor costs. Attached Figure Description

Detailed Implementation

[0035] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the embodiments and accompanying drawings. The illustrative embodiments and descriptions of this utility model are only used to explain this utility model and are not intended to limit this utility model.

[0036] Example 1

[0037] This embodiment 1 provides an online automatic cleaning device, such as... Figure 1 As shown, it includes a cleaning component and a drying component;

[0038] Please refer to Figure 1 As shown, the cleaning assembly realizes the flushing of the inner wall of the pipe and the purging of residual water, including a water storage tank 1, a compressor pump 4, multiple spray cleaning balls 10 and a fluid pipe 19;

[0039] Specifically, the top of the water tank 1 is connected to an air inlet 21 for connecting to external compressed gas 16. The bottom of the water tank 1 is fixed to the ground by a base 3 for storing cleaning medium 2, such as water or special cleaning fluid, and temporarily storing compressed air. The compression pump 4 is connected to the bottom of the water tank 1 and the fluid pipe 19 respectively to pressurize the cleaning medium in the water tank 1, generally to 0.5-1.5MPa, and then transported to the spray cleaning ball 10 through the fluid pipe 19. The spray cleaning ball 10 is distributed along the length of the air inlet and outlet pipe 17, such as in the horizontal section, vertical section and bend. In this embodiment, in order to ensure the cleaning effect of the pipe, there are 10 sets of spray cleaning balls 10, which are evenly distributed along the horizontal section, vertical section and bend of the air inlet and outlet pipe 17. The distance between two adjacent sets of spray cleaning balls 10 is ≤2m, and they are densely arranged at pipe bends and diameter changes to ensure the cleaning coverage of the inner wall of the pipe. It should be noted that in this embodiment, the spray cleaning ball 10 can be of various models, and its specific structure is the existing technology. For example, the surface of the spray cleaning ball 10 is evenly distributed with spray holes of 3mm-5mm diameter, distributed at an angle of 45°-90°. Driven by the reaction force of the cleaning medium spray, the spray cleaning ball 10 rotates. During the rotation, the spray holes continuously spray the cleaning medium 2, forming a vortex flow pattern, which effectively cleans the residue in the container, that is, achieves 180°-360° circumferential coverage of the inner wall of the pipe.

[0040] Meanwhile, after the inner wall of the air inlet and exhaust duct 17 is flushed by the cleaning medium 2, the cleaning medium 2 carries the stripped contaminants to the drain valve and discharges them. The cleaning component then introduces compressed gas 16 into the air inlet and exhaust duct 17 through the fluid pipe 19, which carries away the residual medium on the inner wall of the air inlet and exhaust duct. After the residual medium is discharged, the entire duct is dried through the drying component connected to the air inlet and exhaust duct.

[0041] Specifically, please refer to Figure 1 As shown, the drying assembly is used to construct a closed-loop drying cycle, including an exhaust device 5, a drying device 9, and an air inlet device 13 connected in sequence. The air inlet device 13 includes a second filter 11, an air inlet heating device 12, and an air inlet fan 14. The inlet of the air inlet fan 14 is connected to an air inlet duct 18, and the air inlet fan 14, the air inlet heating device 12, and the second filter 11 are connected in sequence to supply air, heat air, and filter air, respectively, providing clean and dry air to the drying device 9. The drying device 9 is located behind the air inlet device 13. An observation window 8 is opened on the front of the drying device 9 for visually inspecting the drying status of the inner wall of the duct. The bottom of the drying device 9 integrates a drain outlet, which is connected to the air inlet and exhaust ducts 17 to receive the dry air delivered by the air inlet device 13. The exhaust device 5 is located behind the drying device 9 and includes a first filter 6 with the same precision as the air inlet device 13. The outlet of the exhaust device 5 is connected to an exhaust duct 7 to discharge the air carrying moisture during the drying process.

[0042] In summary, this invention forms a closed-loop cleaning path of "cleaning medium spraying - residual water purging - drying". The entire process from cleaning to drying can be completed online without disassembling the pipeline. This not only avoids the risk of microbial contamination caused by residual water, but also improves cleaning efficiency through integrated design, ensuring that the inner wall of the pipeline quickly reaches a dry and clean state after cleaning. It effectively solves the problems of inefficiency, incompleteness and improper residual water treatment in existing technologies.

[0043] Example 2

[0044] Because residual water will be discharged during the automatic cleaning process in the entire cleaning pipeline, this embodiment provides an online automatic cleaning device based on embodiment 1, such as... Figure 1 As shown, it also includes a drainage system, which includes drain valves located at the lowest point of the pipe and at the bottom of the drying equipment 9. The cleaning medium after rinsing is discharged from the drain valves. Specifically, the drain valves include a first drain valve 15 and a second drain valve 20. The first drain valve 15 is set at the lowest horizontal section of the air inlet and outlet pipe 17 to drain water accumulated in the lower part of the pipe. The second drain valve is located at the end of the exhaust pipe to prevent residual water from stagnating at the end of the pipe. The bottom of the drying equipment 9 has its own drain outlet. Each drain valve and drain outlet is directly connected to the pipe, forming a three-dimensional drainage network of "the lowest point of the pipe + the end + the bottom of the equipment" to ensure that the residual medium is discharged without dead corners.

[0045] Example 3

[0046] To improve the stability and consistency of cleaning quality and reduce manual intervention, this embodiment provides an online automatic cleaning device based on Embodiment 2, such as... Figure 1 As shown, it also includes a control system, which is electrically connected to the cleaning and drying components respectively. The control system collects pressure, liquid level and temperature sensor signals in real time, and automatically adjusts parameters such as compressor pump pressure, spraying time and drying temperature. The control system realizes signal transmission to each component, forming an automated closed loop of "sensor feedback-logic processing-equipment control".

[0047] The working process of this utility model:

[0048] Inject cleaning medium 2 into water storage tank 1, connect compressed gas 16 and set an appropriate pressure.

[0049] The control system starts the compressor pump 4, pressurizes the cleaning medium in the water storage tank 1, and then transports it through the fluid pipeline 19 to the spray cleaning balls 10 distributed along the air inlet and outlet pipeline 17. The spray holes on the surface of the spray cleaning balls 10 spray the cleaning medium onto the inner wall of the pipeline. The reaction force of the cleaning medium drives the spray cleaning balls to rotate, and flushes the inner wall of the pipeline from multiple angles and in all directions for a preset cleaning time.

[0050] After cleaning is completed, the cleaning components switch to the purging mode. Compressed air 16 in the water tank 1 is introduced into the air inlet and outlet pipe 17 through the fluid pipe 19, pushing the residual cleaning medium in the pipe to flow towards the drain valve. At the same time, the trace amount of residual water attached to the inner wall of the pipe is purged. The first drain valve 15 located at the lowest horizontal section of the pipe, the second drain valve 20 at the end of the exhaust pipe 7, and the drain port at the bottom of the drying equipment 9 are opened simultaneously to discharge the flushing sewage and the purging residual liquid.

[0051] The air inlet device 13 introduces pre-treated clean and dry air into the air inlet and outlet duct 17. The dry air circulates within the duct, absorbing residual moisture, and is then discharged through the exhaust device 5, forming a drying cycle. This process continues for a period of time to ensure that the moisture in the duct is fully removed.

[0052] The operator visually inspects the inner wall of the pipes through the observation window 8 on the front of the drying equipment 9 to check for any remaining water droplets or watermarks, thus determining whether the drying status meets the standards. If it does not meet the standards, the drying process is repeated until the requirements are met.

[0053] The specific embodiments described above further illustrate the purpose, technical solution, and beneficial effects of this utility model. It should be understood that the above description is only a specific embodiment of this utility model and is not intended to limit the scope of protection of this utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the scope of protection of this utility model.
