Description

Technical Field

[0001] This utility model relates to the field of refrigeration technology, and in particular to an ice-water circulation system for a filling machine. Background Technology

[0002] In filling machine applications, controlling the refrigeration temperature is one of the key factors in ensuring product quality and extending equipment life. Traditionally, many filling machine refrigeration systems rely on compressors to maintain the required low-temperature environment. However, these traditional refrigeration compressors have some inherent problems, particularly in terms of the frequency of failures and the complexity of maintenance during operation.

[0003] When a compressor malfunctions, not only does it require significant time for diagnosis and repair, but it can also disrupt the production line, impacting efficiency. Furthermore, frequent maintenance increases operating costs and reduces the company's economic benefits. Additionally, the unpredictable performance of the compressor makes precise temperature control difficult, potentially affecting the quality stability of the filled products. Utility Model Content

[0004] This invention provides a chilled water circulation system for a filling machine to solve the problems of frequent compressor refrigeration failures and complex maintenance in the prior art, thereby achieving stable and efficient temperature control and lower operating costs.

[0005] This utility model provides a filling machine ice water circulation system, comprising: a circulating water tank for storing soft water for circulation; a pump unit disposed on the outlet side of the circulating water tank, including a first pump unit for drawing soft water from the circulating water tank; an ice water heat exchanger disposed downstream of the pump unit, wherein a low-temperature fluid flows through the ice water heat exchanger, and the soft water exchanges heat with the low-temperature fluid during the process of passing through the ice water heat exchanger; and a filling machine circuit including an inlet pipe and a return pipe, wherein the inlet pipe is connected to the ice water heat exchanger, the return pipe is connected to the return side of the circulating water tank, and the filling machine unit is disposed between the inlet pipe and the return pipe.

[0006] According to one embodiment of this utility model, the circulating water tank is equipped with a level sensor to detect the amount of soft water stored in the tank. The level sensor ensures that the system can monitor the amount of soft water stored in real time, preventing system operation interruptions due to insufficient water.

[0007] According to one embodiment of this utility model, the circulating water tank is provided with a water inlet for injecting soft water, and the water inlet is connected to a soft water source. The connection to the soft water source allows for timely replenishment of soft water, ensuring the continuity and stability of the system.

[0008] According to one embodiment of this utility model, a soft water direct supply pipeline is provided between the soft water source and the chilled water heat exchanger, so as to directly supply soft water through the soft water source when the pump unit is shut down. The soft water direct supply pipeline can provide an uninterrupted supply of cooling water when the pump unit is under maintenance or malfunctioning, thereby improving the reliability of the system.

[0009] According to one embodiment of this utility model, the circulating water tank is equipped with a temperature sensor for detecting the water temperature inside the tank. The application of the temperature sensor enables precise control of the water temperature, helping to maintain a stable cooling effect.

[0010] According to one embodiment of this utility model, the circulating water tank is provided with an overflow hole; the overflow hole is located at the top of the circulating water tank, or the distance between the overflow hole and the top of the circulating water tank in the height direction is less than the distance between the overflow hole and the bottom of the circulating water tank. The overflow hole design prevents excessive water from entering the circulating water tank, ensuring the safe operation of the system.

[0011] According to one embodiment of this utility model, the circulating water tank is connected to a cleaning pipeline for injecting cleaning liquid into the circulating water tank and a discharge pipeline for discharging the cleaning liquid. The cleaning and discharge functions ensure the cleanliness of the inside of the circulating water tank, extend the service life of the equipment, and maintain high efficiency.

[0012] According to one embodiment of this utility model, the pump unit includes a second pump unit configured identically to the first pump unit; the second pump unit is connected in parallel with the first pump unit between the circulating water tank and the chilled water heat exchanger, and during system operation, either the first pump unit or the second pump unit is started. The parallel connection of the pump units improves system redundancy and enhances system reliability and availability.

[0013] According to one embodiment of this utility model, multiple filling machine units are connected in parallel between the inlet pipe and the return pipe. The multiple parallel filling machine units increase the system's flexibility and processing capacity, adapting to different production needs and ensuring maximum flow rate of the circulating soft water, resulting in higher circulation efficiency.

[0014] According to one embodiment of this utility model, soft water output from the outlet side of the circulating water tank sequentially passes through the pump unit, the ice water heat exchanger, and the filling machine circuit before returning to the return side of the circulating water tank, forming a filling machine ice water circulation loop; wherein, at least two filling machine ice water circulation loops are connected in parallel between the outlet and return sides of the same circulating water tank. The parallel ice water circulation loops further ensure maximum utilization of the circulating soft water flow, while also ensuring that other loops can still operate normally even if one loop malfunctions.

[0015] The ice-water circulation system for a filling machine provided by this utility model uses a circulating water tank to store soft water as a cooling medium, and a pump unit is configured on the outlet side of the circulating water tank. This pump unit includes a first pump group to draw and push the soft water into the subsequent cooling process. The soft water then flows through an ice-water heat exchanger located downstream of the pump unit. During this process, the soft water exchanges heat with the low-temperature fluid flowing inside the ice-water heat exchanger, thus being effectively cooled. The cooled soft water then flows into the filling machine unit in the filling machine circuit through the inlet pipe, providing the required low-temperature environment, and finally returns to the return side of the circulating water tank through the return pipe, forming a closed and efficient cooling cycle. This design avoids the frequent failures and complex maintenance problems common in traditional compressor refrigeration systems, achieves more stable and efficient temperature control, and reduces operating costs. This invention, through the design of an ice-water circulation system, not only solves many defects faced by compressor refrigeration in existing filling machines, but also provides a stable and reliable low-temperature guarantee for the filling machine, thereby improving production efficiency and product quality, while reducing maintenance needs and energy consumption, and achieving lower operating costs.

Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0022] The following is combined with Figure 1 This invention describes the specific implementation of the ice water circulation system for a filling machine.

[0023] This utility model provides a filling machine ice water circulation system, including: a circulating water tank 10 for storing soft water for circulation; a pump unit, located on the outlet side of the circulating water tank 10, including a first pump unit 11 for drawing soft water from the circulating water tank 10; an ice water heat exchanger 12, located downstream of the pump unit, in which a low-temperature fluid flows, and the soft water exchanges heat with the low-temperature fluid during the process of passing through the ice water heat exchanger 12; and a filling machine circuit, including an inlet pipe 13 and a return pipe 14, wherein the inlet pipe 13 is connected to the ice water heat exchanger 12, the return pipe 14 is connected to the return side of the circulating water tank 10, and a filling machine unit 20 is arranged between the inlet pipe 13 and the return pipe 14.

[0024] Specifically, a complete cooling circulation path is formed by introducing a combination design of circulating water tank 10, pump unit, chilled water heat exchanger 12, and filling machine circuit. Circulating water tank 10, as the heart of the system, is responsible for storing soft water for cooling and maintaining a stable supply. The pump unit, located on the outlet side of circulating water tank 10, draws soft water from the tank and provides sufficient pressure to allow it to flow into subsequent cooling stages. Next, the soft water flows through chilled water heat exchanger 12, located downstream of the pump unit. Here, the soft water undergoes efficient heat exchange with the low-temperature fluid (such as ice water) circulating inside the heat exchanger 12, achieving rapid cooling. The cooled soft water is then guided to filling machine unit 20 through inlet pipe 13, providing the necessary low-temperature environment for the filling process and ensuring product quality. Finally, the cooled soft water returns to the return side of circulating water tank 10 through return pipe 14, ready for the next cycle.

[0025] In use, the ice water circulation system of the filling machine first draws soft water from the circulating water tank 10, pressurizes it through the pump unit, and sends it to the ice water plate heat exchanger 12 for heat exchange and cooling. Then, the cooled soft water is transported to each filling machine unit 20 through the water inlet pipe 13 to maintain the required low temperature working conditions. Finally, the used soft water returns to the circulating water tank 10 through the return water pipe 14 to complete a complete circulation process.

[0026] Furthermore, the aforementioned chilled water plate heat exchanger 12 preferably employs highly efficient heat exchange materials and technologies to ensure rapid and effective reduction of soft water temperature even under high load conditions. In addition, to improve system reliability and redundancy, the pump unit may include two or more pump sets that can operate alternately or simultaneously to meet different flow demands or to immediately switch to a standby pump to continue operation when one pump fails, without affecting production. Simultaneously, the circulating water tank 10 may also be equipped with a level sensor and an automatic water replenishment device to replenish soft water promptly when it is insufficient, preventing system shutdown due to insufficient water volume.

[0027] According to one embodiment of this utility model, the circulating water tank 10 is equipped with a level sensor to detect the amount of soft water stored in the tank. The level sensor ensures that the system can monitor the amount of soft water stored in real time, preventing system interruptions due to insufficient water volume. Specifically, the introduction of the level sensor provides an automated monitoring method for the system, continuously monitoring the amount of soft water stored in the circulating water tank 10 and feeding real-time data back to the control system. When the soft water level is detected to be below a preset safety threshold, the level sensor will trigger an alarm or directly control the connected water injection device to automatically replenish soft water, ensuring that the tank always maintains sufficient water volume to sustain normal system operation. Furthermore, the level sensor can also work in conjunction with the pump unit; for example, it can automatically stop the pump when the water volume is insufficient, preventing equipment damage caused by idling, thereby further protecting system stability and extending equipment lifespan.

[0028] According to one embodiment of this utility model, the circulating water tank 10 is provided with a water inlet for injecting soft water, which is connected to a soft water source 15. The connection to the soft water source 15 allows for timely replenishment of soft water, ensuring the continuity and stability of the system. Specifically, the connection between the water inlet and the soft water source 15 ensures that the system can automatically and promptly replenish soft water during operation, maintaining the water level in the circulating water tank 10 at an ideal level. When the level sensor detects that the soft water storage level is lower than the set value, the control system automatically starts the water injection program, introducing an appropriate amount of soft water from the connected soft water source 15 through the water inlet to quickly restore the required water level. This automated water replenishment mechanism not only avoids system interruptions caused by untimely manual water addition but also reduces the workload of operators and potential human error.

[0029] Furthermore, to ensure the injected water quality meets requirements, the soft water source 15 preferably undergoes a pretreatment device to remove impurities and hardness components, thereby preventing scale buildup, protecting the chilled water heat exchanger 12 and other components from damage, and further enhancing the system's stability and reliability. In this way, this implementation effectively ensures the continuous operation of the filling machine's chilled water circulation system, improves production efficiency, and reduces maintenance costs.

[0030] According to one embodiment of this utility model, a soft water direct supply pipeline 16 is provided between the soft water source 15 and the chilled water heat exchanger 12 to directly supply soft water through the soft water source 15 when the pump unit is shut down. The soft water direct supply pipeline 16 provides an uninterrupted supply of cooling water during pump unit maintenance or malfunction, improving system reliability. Specifically, the soft water direct supply pipeline 16 provides a redundant water supply path for the system, ensuring that the cooling process is not interrupted when the pump unit is shut down due to maintenance or malfunction. When the pump unit stops working, the control system automatically switches to direct supply mode, supplying soft water directly from the soft water source 15 to the chilled water heat exchanger 12 through the soft water direct supply pipeline 16. Thus, even when the pump unit is not operating normally, the cooling system can continuously provide the necessary low-temperature environment for the filling machine, maintaining the continuity of the production process.

[0031] In addition, the soft water direct supply pipeline 16 is preferably equipped with a flow control valve and a check valve to ensure that soft water can flow safely and stably into the chilled water plate heat exchanger 12 as needed, while preventing backflow. To further optimize operation, pressure sensors and temperature sensors can also be installed on the direct supply pipeline to monitor the water flow status in real time and feed the data back to the control system for timely adjustment and response.

[0032] According to one embodiment of this utility model, the circulating water tank 10 is equipped with a temperature sensor for detecting the water temperature inside the tank. The application of the temperature sensor enables precise control of the water temperature, helping to maintain a stable cooling effect. Specifically, the temperature sensor allows the water temperature inside the circulating water tank 10 to be monitored in real time and accurately fed back to the control system. By comparing the detected temperature data with a preset ideal temperature range, the control system can quickly make adjustments to ensure that the water temperature is always kept within the optimal range. For example, if the temperature sensor detects that the water temperature is too high, the system can automatically increase the cooling intensity or activate backup cooling measures; conversely, if the water temperature is too low, unnecessary energy waste can be avoided by reducing the cooling capacity.

[0033] Furthermore, temperature sensors can assist in achieving more precise temperature gradient management. Different filling processes may require different cooling temperatures, and temperature sensors can help the system dynamically adjust according to actual production requirements to meet the optimal cooling conditions for specific products. To further optimize the system's response speed and accuracy, temperature sensors are preferably used in conjunction with intelligent algorithms to predict temperature change trends and make adjustments in advance, thereby preventing temperature fluctuations from affecting the production process.

[0034] According to one embodiment of this utility model, the circulating water tank 10 is provided with an overflow hole; the overflow hole is located at the top of the circulating water tank 10, or the distance between the overflow hole and the top of the circulating water tank 10 in the height direction is less than the distance between the overflow hole and the bottom of the circulating water tank 10. The overflow hole design prevents excessive water from entering the circulating water tank 10, ensuring the safe operation of the system. Specifically, the overflow hole is designed to prevent the water volume in the circulating water tank 10 from exceeding the safety limit, thereby avoiding system failures or safety hazards caused by excessive water intake. When soft water is added to the circulating water tank 10 through the water inlet, if the water volume is excessive due to some reason (such as control system failure or human error), the overflow hole will act as a key safety valve. The overflow hole located at or near the top of the circulating water tank 10 can ensure that excess water exceeding the set capacity can be discharged in time, rather than accumulating in the tank and causing pressure increases or other problems.

[0035] Furthermore, the overflow hole's location is designed with convenience and safety in mind during actual operation. It is positioned close to the top of the circulating water tank 10 but far from the bottom, ensuring that in the event of an abnormal rise in the tank's water level, overflow water can quickly flow back through the overflow hole to a suitable drainage system or collection device, without affecting the normal water level in the tank or the stable operation of the system.

[0036] According to one embodiment of this utility model, the circulating water tank 10 is connected to a cleaning pipeline 17 for injecting cleaning liquid into the circulating water tank 10 and a discharge pipeline 18 for discharging the cleaning liquid. The cleaning and discharge functions ensure the cleanliness of the interior of the circulating water tank 10, extending the equipment's service life and maintaining high efficiency. Specifically, when cleaning is required, cleaning liquid (such as disinfectant, cleaning agent, or other specialized cleaning solution) can be injected into the circulating water tank 10 through the cleaning pipeline 17 (CIP pipeline). The cleaning liquid circulates thoroughly within the tank, completely removing any potentially accumulated dirt, algae, microorganisms, or mineral deposits. If these substances are not removed promptly, they may lead to water quality deterioration, reduced system efficiency, or even equipment damage.

[0037] After the cleaning process is complete, the cleaning liquid containing dirt and impurities can be safely discharged through the discharge line 18, ensuring that all contaminants are effectively removed. The discharge line 18 is preferably designed to include one or more control valves, allowing operators to flexibly control the discharge process as needed, while preventing accidental leakage from the circulating water tank 10. Furthermore, the discharge line 18 can also be connected to a dedicated wastewater treatment system to meet environmental protection requirements.

[0038] According to one embodiment of this utility model, the pump unit includes a second pump unit 19 configured identically to the first pump unit 11. The second pump unit 19 is connected in parallel with the first pump unit 11 between the circulating water tank 10 and the chilled water heat exchanger 12. During system operation, either the first pump unit 11 or the second pump unit 19 is selectively started. The parallel connection of the pump units improves system redundancy, enhancing system reliability and availability. Specifically, the parallel connection of the first pump unit 11 and the second pump unit 19 provides significant redundancy and flexibility to the system. Under normal operating conditions, the control system selects to start one of the pump units (e.g., the first pump unit 11) according to actual needs to meet the current cooling water flow requirements. When a failure or maintenance is detected in the operating pump unit, the control system can seamlessly switch to another pump unit (e.g., the second pump unit 19) to ensure uninterrupted cooling water supply.

[0039] According to one embodiment of this utility model, multiple filling machine units 20 are connected in parallel between the inlet pipe 13 and the return pipe 14. The multiple parallel filling machine units 20 increase the system's flexibility and processing capacity, adapting to different production needs and ensuring maximum flow of circulating soft water, resulting in higher circulation efficiency. Specifically, when multiple parallel filling machine units 20 work simultaneously, the total system capacity can be significantly increased to meet the needs of large-scale production and peak periods. Each unit operates independently without affecting others, ensuring that even if individual units malfunction or require maintenance, other units can continue to operate, maintaining overall production capacity. By rationally configuring the connecting pipes and valves between the filling machine units 20, soft water can be evenly distributed throughout the system, avoiding local overload or insufficient flow problems. The parallel design allows for more water flow paths, thereby ensuring maximum soft water flow and improving the efficiency of the entire chilled water circulation system. The parallel arrangement of multiple filling machine units 20 not only increases the system's flexibility and processing capacity but also achieves higher circulation efficiency by optimizing the soft water circulation path and flow distribution.

[0040] According to one embodiment of this utility model, soft water output from the outlet side of the circulating water tank 10 sequentially passes through the pump unit, the chilled water heat exchanger 12, and the filling machine circuit before returning to the return side of the circulating water tank 10, forming a filling machine chilled water circulation loop. At least two filling machine chilled water circulation loops are connected in parallel between the outlet and return sides of the same circulating water tank 10. The parallel chilled water circulation loops further ensure maximum utilization of the circulating soft water flow, while also ensuring that other loops can continue to operate normally even if one loop malfunctions. Specifically, by connecting multiple chilled water circulation loops in parallel, the system can more effectively distribute the soft water flow, ensuring that each loop receives sufficient cooling water supply, thus improving the cooling efficiency of the entire system. Each circulation loop operates independently without interference. If one loop fails or requires maintenance, the other loops can continue to operate, preventing the entire system from shutting down and enhancing the system's reliability and fault tolerance.

[0041] Furthermore, the number of parallel chilled water circulation loops is closely related to the capacity of the circulating water tank 10 and the number of filling machine units 20 in each filling machine loop. The specific configuration can be optimized according to actual production needs and system parameters. Specifically, the capacity of the circulating water tank 10 determines the amount of soft water that can be stored in the system. A larger tank can not only support more or larger flow rates of chilled water circulation loops, but also provide better buffering capacity to cope with sudden increases in cooling demand or temporary adjustments. At the same time, the number of filling machine units 20 in each chilled water circulation loop directly affects the cooling water flow rate required for that loop; more filling machine units 20 require a larger flow rate to ensure that all units receive sufficient cooling. Different production lines may have different filling speeds and product types, so it is necessary to flexibly adjust the number of filling machine units 20 in each loop to adapt to diverse needs.
