Description

Technical Field

[0001] This utility model is a multi-stage temperature control device for a collection tank, belonging to the field of temperature control. Background Technology

[0002] In the context of a low-carbon economy, energy conservation and efficiency improvement have become the most pressing tasks for every industry. Some materials generated by low-carbon industries require ultra-low temperature environments, and are often collected using cryogenic liquid collection tanks such as liquid nitrogen or cryogenic collection tanks with temperature control devices.

[0003] Using cryogenic liquids such as liquid nitrogen to collect materials in cryogenic collection tanks requires the use of liquid nitrogen and regular checks and replenishment by staff, resulting in high labor intensity and low automation levels. As factories increasingly demand automation and intelligence, cryogenic collection tanks with temperature control devices are gradually being adopted. However, current processes use refrigeration units or liquid nitrogen to cool the collection tank to the required operating temperature, achieving the process requirements for material condensation and collection. The material condenses in an ultra-low temperature environment. Current temperature control devices cool the entire collection tank, and once the temperature is constant, the collection tank is connected to the material production line. After the material enters the collection tank, it is kept at a low temperature. The environment causes materials to condense, but this method has low material condensation efficiency, and the amount of material collected in the same tank at one time is small, requiring repeated feeding and collection. In some cases, it is even necessary to disassemble the collection tank and reinstall it at a point where liquid nitrogen is used to freeze the collected material in order to meet the control requirements. This not only results in a long online working cycle for the collection tank and high energy consumption, but also requires operators to connect and disconnect the collection tank from the material generation system multiple times, leading to a large amount of operation and low work efficiency. Therefore, this utility model adjusts the cooling method of the temperature control device of the collection tank and proposes a multi-stage temperature control device for the collection tank to improve the material condensation efficiency, increase the amount of material collected in the same tank, and reduce the operation of the collection tank. Utility Model Content

[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a multi-stage temperature control device for a collection tank.

[0005] To achieve the above objectives, this utility model is implemented through the following technical solution:

[0006] A multi-stage temperature control device for a collection tank includes a collection tank and a cooling cylinder. The collection tank is located inside the cooling cylinder. An upper cooling coil, a middle cooling coil, and a lower cooling coil are welded to the outer wall of the cooling cylinder. A water storage tank is provided on one side of the collection tank. Water inlet pipes are connected to one side of the upper, middle, and lower cooling coils, and water outlet pipes are connected to the other side of the upper, middle, and lower cooling coils. The water outlet pipes are connected to the water storage tank. A booster pump is provided on the other side of the collection tank. The booster pump has a suction pipe and a discharge pipe. A common water receiving tray is provided on the discharge pipe. The water inlet pipe is connected to the common water receiving tray, and a solenoid valve is provided on each water inlet pipe. A condenser is connected to the suction pipe.

[0007] Furthermore, mounting brackets are fixedly installed on the cooling cylinder near the upper cooling coil, the middle cooling coil, and the lower cooling coil. Temperature sensors are installed on the mounting brackets, and the temperature sensors have detection probes.

[0008] Furthermore, the temperature sensor has a detection probe that contacts the collection tank, and each collection tank has a through-hole for the detection probe to pass through. A separate control unit for controlling the temperature sensor is located on one side of the collection tank, and the control unit is an electrical control box.

[0009] Furthermore, three semiconductor coolers are installed on the inner wall of the storage tank. The semiconductor coolers are semiconductor cooling chips. The cooling end of the semiconductor cooler is located inside the storage tank, and the heating end of the semiconductor cooler is located outside the storage tank.

[0010] Furthermore, the heating end of the semiconductor cooler is equipped with heat sinks, and a protective component is fitted on the outside of the water storage tank.

[0011] Furthermore, the protective components include a protective frame, on which multiple mounting plates are fixedly mounted, and the mounting plates are fixed to the outer wall of the storage tank with screws.

[0012] Furthermore, the heat sink is located inside the protective frame, and an integrated protective mesh is fixedly installed on the end face of the protective frame facing the heat sink. A blower assembly is also installed inside the protective frame.

[0014] The beneficial effects of this utility model are:

[0015] The collection tank is connected to the material production system. Before material collection begins, the upper, middle, and lower cooling coils are supplied with water through inlet pipes and a booster pump. The water is then cooled by a condenser, thus lowering the temperature inside the collection tank. Once the cooling tank reaches a certain temperature, two solenoid valves open the inlet pipes of the upper and middle cooling coils, leaving only the lower cooling coil to continue cooling the tank. The temperatures of the upper, middle, and lower cooling coils are then controlled and kept constant at the set temperature. Material is then introduced into the collection tank. When the material reaches a suitable height inside the tank, the corresponding middle and lower cooling coils are activated. Attached Figure Description

[0024] Please see Figure 1-2 This utility model provides a multi-stage temperature control device for a collection tank, including a collection tank 1 and a cooling cylinder 2. The collection tank 1 is located inside the cooling cylinder 2. An upper cooling coil 3, a middle cooling coil 4, and a lower cooling coil 5 are welded to the outer wall of the cooling cylinder 2. A storage water tank 6 is provided on one side of the collection tank 1. A water inlet pipe 7 is connected to one side of each of the upper cooling coil 3, the middle cooling coil 4, and the lower cooling coil 5. A water outlet pipe 8 is connected to the other side of each of the upper cooling coil 3, the middle cooling coil 4, and the lower cooling coil 5. The water outlet pipe 8 is connected to the storage water tank 6. A booster pump 9 is provided on the other side of the collection tank 1. The booster pump 9 has a suction pipe 10 and a water outlet pipe 11. A common water receiving tray 12 is provided on the water outlet pipe 11. The water inlet pipe 7 is connected to the common water receiving tray 12, and a solenoid valve 13 is provided on each of the water inlet pipes 7. A condenser 14 is connected to the suction pipe 10.

[0025] See Figure 1 Mounting brackets 15 are fixedly installed on the cooling cylinder 2 near the upper cooling coil 3, the middle cooling coil 4, and the lower cooling coil 5. Temperature sensors 16 are installed on the mounting brackets 15. The temperature sensors 16 have detection probes that contact the collection tank 1. The collection tank 1 has a through-hole for the detection probes to pass through. A control unit for controlling the temperature sensors 16 is located on one side of the collection tank 1. The control unit is an electrical control box. The temperature sensors 16 detect the temperature of the collection tank 1 in the upper, middle, and lower parts, thereby realizing the subsequent temperature control work.

[0026] See Figure 1 and Figures 3-5Three semiconductor coolers 17 are installed on the inner wall of the water storage tank 6. Each semiconductor cooler 17 is a semiconductor cooling chip. The cooling end of each semiconductor cooler 17 is located inside the water storage tank 6, while the heating end is located outside the water storage tank 6. A heat sink 18 is installed on the heating end of each semiconductor cooler 17. A protective assembly is fitted on the outer side of the water storage tank 6. The protective assembly includes a protective frame 19, on which multiple mounting pieces 20 are fixed. The mounting pieces 20 are fixed to the outer wall of the water storage tank 6 with screws. The heat sink 18 is located inside the protective frame 19. An integrated protective net 21 is fixed on the end face of the protective frame 19 facing the heat sink 18. A blower assembly is also installed inside the protective frame 19. The blower assembly includes a blower frame 22, on which a cooling fan 23 is installed. A cooling fan 23 is fixed on the outer side of the blower frame 22. Multiple auxiliary mounting plates 24 are fixed to the inner wall of the protective frame 19 with screws. The water storage tank 6 has water filling and water outlet pipes, each equipped with a control valve. The semiconductor cooler 17 further cools the water inside the water storage tank 6. The heat sink 18 is connected to the heating end of the semiconductor cooler 17 to dissipate heat from the hot end of the semiconductor cooler 17. To ensure the heat dissipation effect, a cooling fan 23 is installed inside the protective frame 19. The cooling fan 23 blows air towards the heat sink 18. The number of cooling fans 23 is set to multiple, depending on the actual situation. The cooling fan 23 can enhance the heat dissipation effect and improve the performance of the semiconductor cooler 17. In addition, the protective frame 19, together with the protective net 21, prevents external dust from sticking to the heat sink 18 and affecting its performance.

[0027] In use, the cooling cylinder 2 has three independent coils welded to its outer wall at the top, middle, and bottom, allowing for separate control of cooling in different areas and avoiding energy waste from overall temperature control. It consists of a condenser 14, a booster pump 9, and a water storage tank 6. The condenser 14 provides the cooling water source, the booster pump 9 delivers cold water to the coils, and the water storage tank recovers circulating water, forming a closed-loop cooling system. Each set of inlet pipes 7 is equipped with a solenoid valve 13, allowing for individual switching of the cold water supply to the corresponding coil, enabling on-demand start / stop. Therefore, the temperature control process is divided into three stages: pre-cooling, dynamic adjustment, and constant temperature maintenance. Precise temperature control is achieved step-by-step. Before specific materials enter, all solenoid valves 13 are opened, and the booster pump 9 delivers the cooled water from the condenser 14 through the common water tray 12 and inlet pipes 7 to the upper cooling cylinder. In the upper cooling coil 3, the middle cooling coil 4, and the lower cooling coil 5, cold water flows within the coils, reducing the temperature of the cooling cylinder through heat conduction, thereby simultaneously cooling the internal collection tank. Once the cooling cylinder reaches the target pre-cooling temperature, the solenoid valves of the upper cooling coil 3 and the middle cooling coil 4 are closed, leaving only the lower coil to continue cooling. When the material in the collection tank reaches a suitable height, the solenoid valves of the middle and lower coils are opened again to specifically cool the area where the material is located. By adjusting the switching frequency of each set of solenoid valves, the flow rate and duration of cold water in the coils are controlled. The solenoid valves can be individually controlled to control the on / off state or flow rate of the cooling medium in the corresponding coil, directly determining the cooling intensity of that area, stabilizing the temperature of the cooling cylinder at the set value, and ultimately achieving constant temperature control within the collection tank.

[0028] Each section of the coil is equipped with a separate inlet and outlet. The cooling medium can be delivered to the corresponding coil through independent pipes, avoiding mixing of cooling media from different areas and ensuring that the cooling capacity adjustment of one area does not affect other areas. A dedicated control valve, namely solenoid valve 13, is designed. Each independent water circuit's inlet pipe is equipped with a solenoid valve, which can individually control the on / off state or flow rate of the cooling medium in the corresponding coil, directly determining the cooling intensity of that area. In achieving on-demand temperature control, sensors are needed to accurately identify the temperature status of different areas, providing a basis for adjustment. The temperature sensor 16 has a detection probe that can detect the temperature of the upper and middle collection tanks 1, as well as the temperature of the lower collection tank 1. The temperature detection settings for the lower collection tank 1 are configured according to actual conditions. The temperature data from each area's sensor is transmitted separately to the control unit, which can then compare the actual temperature of each area with... The system sets a temperature and determines whether the cooling intensity of a given area needs adjustment. Based on temperature feedback from each area, the control unit adjusts the solenoid valve actuator to achieve differentiated temperature control for different areas. When the temperature of a detected area is higher than the set value, the control unit opens the solenoid valve of the coil in that area, allowing cooling medium to flow in for cooling. When the temperature drops below the set value, the solenoid valve closes, stopping the cooling process. This system is suitable for scenarios with moderate temperature control accuracy requirements. The solenoid valve is an existing component and can be directly replaced with an existing adjustable valve, which is also an existing component. The control unit can adjust the flow rate of the cooling medium according to the temperature deviation to achieve precise temperature stability. The inlet pipe 7, outlet pipe 8, suction pipe 10, and outlet pipe 11 are all installed with flanges. It should be noted that, depending on the actual cooling requirements, a condenser 14 can be installed on each outlet pipe 8 for further cooling.

[0029] Although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
