[0032] The implementation of the present disclosure will be described in detail with reference to the specific drawings as follows:

[0033] Figure 1 It is a schematic structural diagram of an automatic temperature control system for an extraction tank used in a glycine production line provided by an embodiment of the present disclosure. Refer to Figure 1 This automatic temperature control system for the extraction tank used in the glycine production line includes a first water temperature acquisition module 102, a second water temperature acquisition module 103, a control module 104, a heating module 105, and a cooling module 106;

[0035] Both the first water temperature acquisition module 102 and the second water temperature acquisition module 103 are connected to the control module 104, and the control module 104 is respectively connected to the heating module 105 and the cooling module 106;

[0036] The control module 104 is configured to control the working state of the cooling module 106 according to the water temperature information collected by the first water temperature acquisition module 102, and is configured to control the working state of the heating module 105 according to the water temperature information collected by the second water temperature acquisition module 103;

[0037] The heating module 105 is configured to heat the extraction tank 101 according to the heating control instruction of the control module 104, and the cooling module 106 is configured to cool the extraction tank 101 according to the cooling control instruction of the control module 104.

[0038] In this embodiment, in order to make the temperature of the extraction tank 101 collected more accurate and comprehensive, two different water temperature acquisition modules can be set to collect the temperature to meet different requirements.

[0039] In this embodiment, the first water temperature acquisition module 102 and the second water temperature acquisition module 103 are both arranged in the extraction tank 101. The heating module 105 and the cooling module 106 are respectively arranged on both sides of the extraction tank 101. The first water temperature acquisition module 102 is arranged on one side of the heating module 105, and the second water temperature acquisition module 103 is arranged on one side of the cooling module 106. The first water temperature acquisition module 102 and the second water temperature acquisition module 103 are responsible for collecting the initial temperature or the current temperature of the liquid in the extraction tank 101 in real time. The first water temperature acquisition module 102 and the second water temperature acquisition module 103 are arranged in the extraction tank 101, and the water temperature information in the extraction tank 101 can be directly obtained. The heating module 105 and the cooling module 106 are installed on both sides of the extraction tank 101 and are used to control the temperature in the extraction tank 101 to rise or fall. The first water temperature acquisition module 102 is arranged on one side of the heating module 105. At this time, the first water temperature acquisition module 102 is used to monitor the cooling effect in a timely manner. The second water temperature acquisition module 103 is arranged on one side of the cooling module 106. At this time, the second water temperature acquisition module 103 is used to monitor the heating effect in a timely manner. The two cooperate with each other to maintain the stability of the temperature in the extraction tank 101.

[0040] In this embodiment, the first water temperature acquisition module 102 and the second water temperature acquisition module 103 are both connected to the control module 104, and the control module 104 is respectively connected to the heating module 105 and the cooling module 106. The first water temperature acquisition module 102 and the second water temperature acquisition module 103 will transmit the collected water temperature data to the control module 104 in real time. The control module 104, as the core of the entire system, is used to receive the temperature information from the first water temperature acquisition module 102 and the second water temperature acquisition module 103, and analyze and process this temperature information according to the actual required temperature. The control module 104 is also used to issue instructions to and control the heating module 105 and the cooling module 106.

[0041] In this embodiment, the control module 104 is configured to control the working state of the cooling module 106 according to the water temperature information collected by the first water temperature acquisition module 102, and is configured to control the working state of the heating module 105 according to the water temperature information collected by the second water temperature acquisition module 103. After receiving the temperature information from the first water temperature acquisition module 102 and the second water temperature acquisition module 103, the control module 104 processes it and further issues an execution instruction to the heating module 105 or the cooling module 106 to adjust the temperature in the extraction tank 101.

[0042] In this embodiment, the heating module 105 is configured to heat the extraction tank 101 according to the heating control instruction of the control module 104, and the cooling module 106 is configured to cool the extraction tank 101 according to the cooling control instruction of the control module 104. When the temperature information monitored by the first water temperature acquisition module 102 indicates that the temperature in the extraction tank 101 is too high or close to the upper limit set value, the control module 104 will issue an instruction based on this data to control the cooling module 106 to work, so as to enhance the cooling efficiency and thus reduce the temperature in the extraction tank 101, preventing overheating from affecting the product quality or causing safety hazards. On the contrary, when the water temperature information monitored by the second water temperature acquisition module 103 shows that the temperature is too low or has not reached the ideal extraction temperature, the control module 104 will, based on this feedback, adjust or activate the heating module 105 to increase the heat and thus raise the temperature in the extraction tank 101, prompting the temperature in the extraction tank 101 to rise to the target range to ensure that the extraction process is carried out under the optimal temperature conditions. The control module 104 can respectively control the cooling module 106 and the heating module 105 in a targeted manner according to the water temperature information provided by different water temperature acquisition modules to maintain the water temperature in the extraction tank 101 within a suitable range.

[0043] In this embodiment, by setting two water temperature acquisition modules in the extraction tank 101: the first water temperature acquisition module 102 and the second water temperature acquisition module 103, the system can obtain the temperature information of different areas in the extraction tank 101 in real time. This way of zonal monitoring enables the control module 104 to more accurately understand the temperature distribution in the extraction tank 101 and make adjustments according to the actual situation, thereby improving the accuracy of temperature control. The two water temperature acquisition modules are respectively arranged on both sides of the heating module 105 and the cooling module 106, enabling the system to respond more quickly to temperature changes. When the temperature in a certain area deviates from the set value, the corresponding module will be immediately activated to quickly restore the temperature to the target range, thereby enhancing the stability and reliability of the system. The automatic temperature control system avoids unnecessary energy waste by precisely controlling the working states of the heating module 105 and the cooling module 106. The system only starts the corresponding module when needed and adjusts the temperature according to the actual needs, thus realizing the optimal utilization of energy. This design forms a complete closed-loop control system, which can realize the automatic and precise adjustment of the water temperature in the extraction tank 101 and ensure the temperature stability, thus meeting the process requirements of the glycine production line.

[0047] In this embodiment, the switch module 107 plays a role in switching connections. The switch module 107 is connected to the heating module 105, the cooling module 106, and the control module 104. When the control module 104 issues a heating control instruction, the switch module 107 will correspondingly select to connect with the heating module 105, so that the heating module 105 can receive the working signal and start the heating operation. When the control module 104 issues a cooling control instruction, the switch module 107 switches to select to connect with the cooling module 106, enabling the cooling module 106 to start the cooling work.

[0048] In this embodiment, by introducing the switch module 107, it can accurately switch the connection between the heating module 105 and the cooling module 106 according to different instructions of the control module 104, ensuring the accuracy and effectiveness of temperature regulation.

[0049] In an exemplary embodiment of the present disclosure, the switch module 107 includes a single-pole double-throw switch;

[0050] For the single-pole double-throw switch, the stationary terminal is connected to the control module 104, the first moving terminal is connected to the heating module 105, and the second moving terminal is connected to the cooling module 106.

[0051] In this embodiment, the stationary terminal of the single-pole double-throw switch is connected to the control module 104 for receiving the instructions issued by the control module 104. When the control module 104 issues a heating control instruction, the stationary terminal of the single-pole double-throw switch is connected to the first moving terminal, so that the control module 104 is connected to the heating module 105 to realize the control of the heating module 105 and start the heating operation. When the control module 104 issues a cooling control instruction, the stationary terminal of the single-pole double-throw switch is connected to the second moving terminal. At this time, the control module 104 is connected to the cooling module 106, and then controls the cooling module 106 to perform the cooling work.

[0052] In this embodiment, by adopting the design of the single-pole double-throw switch, it can simply and effectively switch the connection between the heating module 105 and the cooling module 106 according to the instructions of the control module 104 to accurately adjust the temperature of the extraction tank 101.

[0055] The heating control module 201 is configured to control the working state of the heating unit 202 according to the control instruction of the control module 104 and the working state of the cooling module 106.

[0056] In this embodiment, the heating control module 201 plays an intermediate coordination and control role. On the one hand, the heating control module 201 is connected to the control module 104 to receive specific control instructions related to heating from the control module 104; on the other hand, it is connected to the cooling module 106, capable of obtaining the working state of the cooling module 106, and controlling the cooling module 106 through the switch module 107. At this time, the heating module 105 is in a conducting state, and the cooling module 106 is in a cut-off state. The heating control module 201 will accurately control the working state of the heating unit 202 according to the instruction of the control module 104.

[0057] By introducing the heating control module 201 and the heating unit 202 in this embodiment, the heating module 105 becomes more intelligent and flexible during operation, can better adapt to complex temperature regulation requirements, and ensure that the temperature in the extraction tank 101 is stably within the ideal range.

[0058] As Figure 2 shown, in an exemplary embodiment of the present disclosure, the cooling module 106 includes a cooling control module 203 and a cooling unit 204;

[0059] The cooling control module 203 is respectively connected to the cooling unit 204, the heating module 105, and the control module 104;

[0060] The cooling control module 203 is configured to control the working state of the cooling unit 204 according to the control instruction of the control module 104 and the working state of the heating module 105.

[0061] In this embodiment, the cooling control module 203 plays an intermediate coordination and control role. On the one hand, the cooling control module 203 is connected to the control module 104 to receive specific control instructions related to cooling from the control module 104; on the other hand, it is connected to the heating module 105, capable of obtaining the working state of the heating module 105, and controlling the heating module 105 through the switch module 107.

The cooling control module 203 will accurately control the working state of the cooling unit 204 according to the instruction of the control module 104.

[0062] In this embodiment, by introducing the temperature reduction control module 203 and the temperature reduction unit 204, the temperature reduction module 106 becomes more intelligent and flexible during operation, can better adapt to complex temperature regulation requirements, and ensures that the temperature in the extraction tank 101 is stably within the ideal range.

[0064] The first warning module 205 is connected to the heating control module 201; and / or, the first warning module 205 is connected to the temperature reduction control module 203.

[0065] In this embodiment, the first warning module 205 is used to detect abnormal conditions of the heating control module 201 or the temperature reduction control module 203. If it is connected to the heating control module 201, when the first warning module 205 detects abnormal conditions in the heating unit 202, such as too high temperature, heating failure, abnormal heating speed, etc., it will trigger the first warning module 205 to send out a warning signal to remind relevant personnel to handle it. If it is connected to the temperature reduction control module 203, when the temperature reduction control module 203 monitors abnormalities in the temperature reduction module 106, such as excessive temperature reduction, temperature reduction failure, etc., it will also cause the first warning module 205 to issue a warning. If the first warning module 205 is connected to both the heating control module 201 and the temperature reduction control module 203, then as long as any one of these two control modules 104 detects an abnormality in its own module, it will trigger the first warning module 205 to work and report the problem to relevant personnel in a timely manner, so as to take measures to ensure the normal operation of the system and the accuracy of temperature regulation.

[0066] In this embodiment, the first warning module 205 is further used to detect the working states of the heating control module 201 and the temperature reduction control module 203. The first warning module 205 is connected to both the heating control module 201 and the temperature reduction control module 203. When the control module 104 issues a heating instruction, at this time the heating module 105 works, and the temperature reduction module 106 should stop working. If it is detected that the temperature reduction module 106 is still in the working state, the first warning module 205 will issue an alarm. When the control module 104 issues a temperature reduction instruction, at this time the temperature reduction module 106 works, and the heating module 105 should stop working. If it is detected that the heating module 105 is still in the working state, the first warning module 205 will issue an alarm.

[0067] In this embodiment, by introducing the first warning module 205, the working states of the heating control module 201 and / or the temperature reduction control module 203 can be monitored in real time, which is convenient for relevant personnel to conduct fault troubleshooting and repair, and improves the stability of the system.

[0074] In this embodiment, the communication module 111 is connected to the control module 104, and the communication module 111 is used to realize data transmission and communication between the control module 104 and the terminal. For example, information such as temperature data and module working status can be transmitted to the remote monitoring terminal, or control instructions from remote can be received.
