Description

Technical Field

[0001] This utility model relates to the field of circulation system technology, specifically a duck egg pickling liquid circulation system. Background Technology

[0002] In the duck egg pickling process, the temperature of the pickling solution is a key factor affecting the pickling process and the quality of the finished product. When the temperature of the pickling solution is too high, microorganisms inside it are prone to grow and multiply in large numbers, which will significantly increase the risk of duck eggs spoiling. On the other hand, if the temperature of the pickling solution is too low, the pickling speed will be greatly slowed down, and the duck eggs may also be pickled unevenly, affecting the quality of the final product. Therefore, in the process of pickling duck eggs, the temperature of the pickling solution must be stably controlled within a suitable range, such as 20-25℃.

[0003] In traditional pickling processes, the pickling liquid is often heated by electric heating or steam heating. However, these traditional heating methods often have problems such as high energy consumption and low thermal efficiency. This not only leads to high energy expenditures in the production process, directly increasing the overall operating cost, but may also limit the product's room for price control and quality optimization due to cost pressures, thereby weakening the product's competitive advantage in the market. Utility Model Content

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Please see Figures 1 to 3 This utility model provides a technical solution.

[0021] A duck egg pickling liquid circulation system includes: a heat pump heat exchange module, the heat pump heat exchange module including an evaporator 11, a compressor 12, and a condenser 9. The tube side outlet of the evaporator 11 is connected to a return water well through a pipe. The shell side of the evaporator 11 is filled with a heat transfer working fluid. The shell side outlet of the evaporator 11 is connected to the inlet of the compressor 12 through a pipe. The outlet of the compressor 12 is connected to the shell side inlet of the condenser 9 through a pipe. The shell side outlet of the condenser 9 is connected to the shell side inlet of the evaporator 11 through a pipe.

[0022] The well water circulation module includes a return water well and a first pipe 10. One end of the first pipe 10 is connected to the return water well, and the other end is connected to the tube inlet of the evaporator 11. Well water is transported from the return water well to the tube inlet of the evaporator 11 through the first pipe 10 using a well water pump.

[0023] The pickling liquid circulation module includes a pickling tank 1, a storage tank 2, and a second pipeline 8. The outlet of the pickling tank 1 is connected to the inlet of the storage tank 2 via a pipeline, and the outlet of the storage tank 2 is connected to the tube-side inlet of the condenser 9 via the second pipeline 8. The pickling liquid is transported from the pickling tank 1 through the storage tank 2 via the second pipeline 8 using a circulation pump, and then to the tube-side inlet of the condenser 9. The tube-side outlet of the condenser 9 is connected to the pickling tank 1 via a pipeline. It utilizes water source heat pump technology to extract low-grade heat energy from well water, resulting in a high coefficient of performance. Compared with traditional electric heating methods, it can save more than 50% of energy. The entire system operates without exhaust emissions, making it environmentally friendly and meeting the requirements of green production.

[0024] The control unit is electrically connected to the well water pump, compressor 12, and circulation pump, respectively.

[0025] The heat transfer medium is Freon refrigerant.

[0026] It also includes a temperature detection component, which includes a first temperature sensor installed in the pickling tank 1 and a second temperature sensor installed on the outlet pipe of the condenser 9. Both the first and second temperature sensors are electrically connected to the control unit.

[0027] Both the evaporator 11 and the condenser 9 are shell-and-tube heat exchangers.

[0028] The storage tank 2 contains a stirring device, which is electrically connected to the control unit. A lever-type control switch 7 (such as a common single-pole single-throw switch) is mounted on the surface of the storage tank 2. The lever pointing upwards indicates the start state, and downwards indicates the off state. The control switch 7 controls the start and stop of the stirring device; moving the lever upwards turns the stirring device on, and moving it downwards turns it off. The control switch 7 also acts as an emergency switch; when the liquid level in the storage tank 2 is too low, it can trigger an emergency shutdown to prevent the stirring device from running dry and causing wear or overheating. A protective cover 3 is fixedly connected to the surface of the storage tank 2. A buoyancy emergency stop assembly is installed inside the protective cover 3. This assembly works in conjunction with the control switch 7 to achieve an emergency shutdown. When the liquid level in the storage tank 2 is too low, the buoyancy emergency stop assembly falls downwards due to the loss of buoyancy, thereby pulling the lever of the control switch 7 downwards, switching it to the off state, and ultimately stopping the stirring device.

[0029] The buoyancy emergency stop assembly includes a buoyancy ball 5 and a pull rope 6. The buoyancy ball 5 is placed inside the protective cover 3. A communication port 4 on the surface of the liquid storage tank 2 allows the inside of the liquid storage tank 2 to communicate with the inside of the protective cover 3, ensuring that the liquid in the liquid storage tank 2 can enter the protective cover 3 to provide buoyancy support for the buoyancy ball 5. One end of the pull rope 6 is fixedly connected to the surface of the buoyancy ball 5, and the other end moves through the protective cover 3 and is connected to the lever of the control switch 7. The specific process is as follows: When the liquid level in the liquid storage tank 2 is normal, the buoyancy ball 5 is suspended by the buoyancy of the liquid, and the pull rope 6 is in a slack state, which does not affect the normal state of the control switch 7. When the liquid level is too low, the buoyancy disappears, and the buoyancy ball 5 falls under the action of gravity. The pull rope 6 pulls the lever of the control switch 7 to move down, so that the stirring device is shut down in an emergency. After the liquid level in the liquid storage tank 2 is restored, the lever of the control switch 7 must be manually moved up to reset before the stirring device can be restarted.

[0030] The specific solution is as follows: Well water circulation: The well water pump delivers well water through the first pipeline 10 to the tube side of the evaporator 11, where it exchanges heat with the liquid heat transfer medium in the shell side of the evaporator 11, and then returns to the return water well from the tube side outlet of the evaporator 11.

[0031] Heat pump cycle: After absorbing heat from the well water, the liquid heat transfer medium in the shell side of evaporator 11 changes phase to low-pressure gas. The low-pressure gas heat transfer medium enters compressor 12 and is compressed into high-pressure, high-temperature gas. The high-pressure, high-temperature gas heat transfer medium enters the shell side of condenser 9 and exchanges heat with the pickling liquid in the tube side of condenser 9. After releasing heat, it condenses into liquid and returns to evaporator 11, completing one cycle.

[0032] Pickling liquid circulation: The circulation pump first transports the pickling liquid in the pickling tank 1 to the storage tank 2, and then through the second pipeline 8 to the tube side of the condenser 9. After absorbing the heat released by the heat transfer medium, it returns to the pickling tank 1 from the tube side outlet of the condenser 9, thereby raising the temperature of the pickling liquid.

[0033] Control and Regulation: The control unit adjusts the operating power of the well water pump and the circulation pump, as well as the opening of the flow regulating valve, based on the temperature signal fed back by the temperature detection component, so that the temperature of the pickling solution is stabilized within the set range.

[0034] In the heating mode of a water source heat pump, the core of the entire system is to extract the heat contained in the well water and transfer it to the duck egg pickling liquid that needs to be heated, so as to achieve the heating of the medium. The specific process is as follows: First, the well water pump delivers the well water, which serves as a low-temperature heat source, through the first pipe 10 to the tube side of the evaporator 11. At this time, the heat transfer medium (usually liquid Freon, referred to as liquid fluorine) in the shell side of the evaporator 11 exchanges heat with the well water in the tube side. After absorbing the heat from the well water, the liquid fluorine undergoes a phase change, transforming from a liquid state into a low-pressure gaseous fluorine (referred to as gaseous fluorine). Subsequently, the low-pressure gaseous fluorine is sent to the compressor 12, which compresses it through mechanical work, transforming the low-pressure gaseous fluorine into a high-pressure, high-temperature gaseous fluorine. The key to this step is to increase the temperature and pressure of the fluoride, making its temperature higher than that of the pickling liquid that needs to be heated, thus creating conditions for subsequent heat release. The high-pressure, high-temperature gaseous fluoride then enters the shell side of condenser 9. At the same time, the circulating pump transports the pickling liquid to be heated along condenser 9 to the tube side of condenser 9, where it comes into contact with the high-temperature, high-pressure gaseous fluoride (indirect heat exchange through the vessel wall, without direct mixing). At this point, the gaseous fluoride releases heat, transferring it to the pickling liquid to be heated, causing the temperature of the pickling liquid to rise. Meanwhile, the gaseous fluoride itself condenses due to heat release, transforming back into liquid fluoride. Finally, the liquid fluoride returns to the shell side of evaporator 11, entering the next cycle. This process is repeated continuously, transferring heat from the water source to the target medium to achieve the heating effect.

[0035] In this embodiment, the stirring device is a rod stirrer with adjustable speed. During operation, the target temperature of the marinating liquid is set to 30°C.

[0036] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
