Description

Technical Field

[0001] This utility model relates to CIP technology, and more particularly to a CIP water and heat energy recovery and utilization device. Background Technology

[0002] Currently, the key production processes for canned carbonated beverages include a can washing system and a mixing and filling system. The can washing system cleans empty cans before they enter the mixing and filling system for filling and capping. Because the mixing and filling system involves food hygiene and safety, it undergoes regular CIP cleaning. The CIP cleaning system cleans and disinfects the mixed filling by passing CIP water at a certain temperature through a centrifugal pump in the CIP tank.

[0003] Patent document with application number "CN202210360684.0" discloses a CIP cleaning system, which includes: a water-using mechanism, a purified water tank, an alkali tank, a water-for-injection tank, a return water mechanism, a first conductivity meter, and a controller. During operation, when the conductivity of the return water meets the requirements, it indicates that the quality of the return water is up to standard. The controller then controls the return water mechanism to output the collected purified water return water to the purified water tank through the first return water pipeline, and to output the collected alkali return water to the alkali tank through the second return water pipeline.

[0004] Patent document with application number "CN200910217438.4" discloses a device including a host computer program module, a slave computer program module, various sensors of the CIP control system, and various actuators of the CIP control system. The host computer program module mainly provides a human-machine interface for operators, offering a vivid, intuitive, and feature-rich integrated user environment for operating the CIP system through several process screens. The slave computer program module mainly receives instructions from the host computer program and automatically executes the corresponding operating procedures according to the CIP cleaning specifications based on the issued instructions and signals from the field instruments and actuators.

[0005] The aforementioned patent documents, in conjunction with existing technologies, reveal the following shortcomings of current CIP water and heat energy recovery and utilization devices:

[0006] In existing technologies, only the mixing and filling system includes CIP cleaning. The tank washing system is not designed for cleaning during CIP; the tanks are simply rinsed with sterile room-temperature water and then directly enter the filling system. Because the tanks contain impurities and foreign matter, neglecting to clean the tank washing system for an extended period poses a hygiene risk. Furthermore, during the CIP system cleaning process, water that does not meet the required temperature is discharged and then returned to the CIP tank for recirculation once it reaches a certain temperature. Utility Model Content

[0007] In order to overcome the shortcomings of the existing technology, this utility model provides a CIP water and heat energy recovery and utilization device, which solves the problems of low cleaning efficiency and high energy consumption.

[0008] The first aspect of this utility model is to provide a CIP water and heat energy recovery and utilization device, including a CIP tank for cleaning, a first centrifugal pump, a mixing and filling system, a first reflux valve, a tank cleaning line, and a liquid recovery heat energy line. The tank cleaning line includes a tank cleaning valve and a tank system. The mixing and filling system is connected to the tank system via a pipeline. The tank cleaning valve is installed on the pipeline between the mixing and filling system and the tank system. The reflux control temperature probe is installed on the output pipeline of the mixing and filling system. The CIP tank, the first centrifugal pump, and the mixing and filling system are sequentially connected end-to-end to form a loop. The liquid recovery... The thermal energy line includes a hot water storage unit, a second centrifugal pump, and a heat exchanger. The input end of the heat exchanger is connected to the output pipeline of the mixing and filling system, and an inlet valve is installed on the pipeline. The heat exchanger, hot water storage unit, and second centrifugal pump are connected in sequence, and an outlet valve is installed at the output end of the heat exchanger. After the reflux control temperature probe reaches the set temperature, the washing tank cleaning valve is opened to perform CIP cleaning on the washing tank system. During the CIP cleaning reflux of the mixing and filling system, before the reflux control temperature probe reaches the set temperature, the CIP reflux water enters the heat exchanger through the inlet valve, and the circulating heating centrifugal pump is turned on to recover and store heat energy.

[0009] In a preferred embodiment of the first aspect of this utility model, the CIP water and heat energy recovery and utilization device further includes a second reflux valve, which is disposed on the same pipeline as the first reflux valve.

[0010] In a preferred embodiment of the first aspect of this utility model, the CIP water and heat energy recovery and utilization device further includes a drain valve, which is disposed between the first return valve and the second return valve.

[0011] In a preferred embodiment of the first aspect of this utility model, the CIP water and heat energy recovery and utilization device further includes a sewage control temperature control probe, which is installed on the pipeline where the first return valve is located.

[0012] In a preferred embodiment of the first aspect of this utility model, the CIP water and heat energy recovery and utilization device further includes a CIP reflux valve and an auxiliary reflux pipeline. The auxiliary reflux pipeline is connected to the output pipeline of the mixing and filling system, and the CIP reflux valve is disposed on the auxiliary reflux pipeline.

[0013] In a first aspect of this utility model, as a preferred embodiment, the CIP water and heat energy recovery and utilization device further includes other return lines, which are connected to the auxiliary return pipeline.

[0015] In a preferred embodiment of the first aspect of this utility model, the heat exchanger is a plate heat exchanger.

[0016] In a preferred embodiment of the first aspect of this utility model, the hot water storage component is a hot water tank.

[0017] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0018] The CIP tank, the first centrifugal pump, and the mixing and filling system are connected sequentially to form a loop. The liquid recovery heat energy line includes a hot water storage unit, a second centrifugal pump, and a heat exchanger. The input end of the heat exchanger is connected to the output pipeline of the mixing and filling system, and an inlet valve is installed on the pipeline. The heat exchanger, the hot water storage unit, and the second centrifugal pump are connected sequentially, and an outlet valve is installed at the output end of the heat exchanger. After the reflux control temperature probe reaches the set temperature, the tank washing tank cleaning valve is opened to perform CIP cleaning on the tank washing tank system. During the CIP cleaning reflux of the mixing and filling system, before the reflux control temperature probe reaches the set temperature, the CIP reflux water enters the heat exchanger through the inlet valve, and the circulating heating centrifugal pump is turned on to recover and store heat energy. On the one hand, by adding temperature control probes and pipelines to the mixed filling system, the washing tank is simultaneously cleaned by CIP when the temperature of the cleaning fluid reaches the set value, thus solving the hygiene hazard. On the other hand, by adding heat exchangers, hot water tanks and centrifugal pumps to the return pipeline, the low-temperature CIP water that was originally to be discharged is recycled by heat exchange and stored in the hot water tank for reuse. Through the linkage cleaning design and heat recovery system, the dual problems of hygiene and energy consumption in the existing technology are solved. Attached Figure Description

On the other hand, by adding a heat exchanger, hot water tank and centrifugal pump to the return pipeline, the low-temperature CIP water that was originally to be discharged is recycled by heat exchange and stored in the hot water tank for recycling.
