[0023] Example

[0024] Please refer to Figure 1 As shown, a titanium flat bar fully automatic monitoring and cooling system includes an annealing water tank, an external circulation water tank 70, a temperature sensor 22, a pumping motor 40, a control circuit 30 and a solenoid valve 81. Among them, a support frame 14 is installed at the bottom of the annealing water tank, a titanium flat bar 90 is inserted into the annealing water tank, and a temperature sensor 22 is installed in the annealing water tank for detecting the water temperature of the annealing water tank. The annealing water tank has a first water inlet and a first water outlet, and the external circulation water tank 70 has a second water inlet and a second water outlet. The first water outlet is connected to the second water inlet through a first pipeline, and the second water outlet is connected to the first water outlet through a second pipeline 80. A pumping motor 40 is installed on the first pipeline, and a solenoid valve 81 is installed on the second pipeline 80. The control circuit 30 is used to receive the water temperature signal collected by the temperature sensor 22, and control the operation of the pumping motor 40 and the solenoid valve 81 (the control circuit 30 is connected to the pumping motor 40 and the solenoid valve 81 through a connecting line 31) according to the water temperature signal.

[0025] By installing the temperature sensor 22 in the annealing water tank, the system can monitor the water temperature change in real time and accurately. The control circuit 30 transmits a signal to the control circuit 30 according to the received water temperature signal when the water temperature signal is higher than the set temperature. The control circuit 30 intelligently adjusts the working state of the pumping motor 40 and the solenoid valve 81 to achieve accurate control of the cooling rate of the titanium flat bar 90. Moreover, the system adopts a fully automatic monitoring method, which can realize real-time monitoring and accurate control of the cooling process of the titanium flat bar 90 without human intervention. This not only reduces the labor intensity of the operator, but also avoids the influence of human factors on the annealing process, and improves production efficiency and product quality.

[0026] The external circulation water tank 70 can cool the water flowing into the annealing water tank by means of a fan. A fan is installed in the external circulation water tank 70, and the control circuit 30 is electrically connected to the fan to control the operation of the fan according to the water temperature signal. The fan can enhance the heat exchange capacity in the external circulation water tank 70, so that the circulating water can dissipate heat faster in the external circulation water tank 70 after flowing through the annealing water tank where the titanium flat bar 90 is located, thereby accelerating the reduction of the water temperature. This significantly improves the cooling efficiency of the system and shortens the annealing and cooling time of the titanium flat bar 90.

[0027] In order to prevent the titanium flat bar 90 from being above the water surface when the water temperature of the annealing water tank is too high, and the titanium flat bar 90 cannot be continuously cooled down, in a preferred embodiment of the utility model, the liquid level information is monitored by a liquid level sensor 21. The liquid level sensor 21 and the temperature sensor 22 constitute a sensor component 20. The liquid level sensor 21 is located above the annealing water tank, and is used to collect the liquid level signal of the annealing water tank and send the liquid level signal to the control circuit 30. The control circuit 30 controls the operation of the pumping motor 40, the fan and the solenoid valve 81.

[0028] When the liquid level in the annealing water tank is at a high liquid level (set liquid level) and the water temperature is higher than the set temperature, the control circuit 30 will turn on the pumping motor 40 to pump away the hot water in the annealing water tank, and at the same time, the external circulation water tank 70 will start to reduce the water temperature through the fan. When the liquid level switch is at a low liquid level, the pumping motor 40 automatically stops, the cooling fan stops, and the water inlet solenoid valve 81 automatically opens to replenish the cooled cold water to the annealing water tank, thereby realizing functions such as automatic circulation, automatic cooling, and automatic water replenishment.

[0029] Please refer to Figure 2 As shown, the control circuit 30 can be implemented by a PLC 32 (programmable logic controller), the input end of the PLC 32 is electrically connected to the liquid level sensor 21 and the temperature sensor 22, and the output end of the PLC 32 is electrically connected to the pumping motor 40, the solenoid valve 81 and the fan. When the above situation occurs, the PLC 32 controls whether the pumping motor 40, the fan and the solenoid valve 81 are working or not.

[0030] In other embodiments, the control circuit 30 may also be constructed by discrete components, see Figure 3As shown, the control circuit 30 may include a first reference voltage source 33, a second reference voltage source 34, a first comparator 38, a second comparator 39, a first electronic switch 36, a second electronic switch 37, and an AND gate 35. The positive input terminal and the negative input terminal of the first comparator 38 are respectively connected to the liquid level sensor 21 and the first reference voltage source 33, the positive input terminal and the negative input terminal of the second comparator 39 are respectively connected to the temperature sensor 22 and the second reference voltage source 34, the two input terminals of the AND gate 35 are respectively connected to the output terminals of the first comparator 38 and the second comparator 39, the output terminal of the AND gate 35 is connected to the control terminal of the first electronic switch 36, the pumping motor 40 and the fan are both connected to the output terminal of the first electronic switch 36, the control terminal of the second electronic switch 37 is connected to the output terminal of the first comparator 38, the output terminal of the second electronic switch 37 is connected to the solenoid valve 81, and the input terminals of the first electronic switch 36 and the second electronic switch 37 are both connected to the external power supply 100.

[0031] The first electronic switch 36 and the second electronic switch 37 can both be implemented by transistors, MOS transistors, relays, etc. For example, the first electronic switch 36 can be constructed by an NPN transistor, and the second electronic switch 37 can be constructed by a PNP transistor, wherein the base, collector, and emitter of the NPN transistor correspond to the control end, input end, and output end of the first electronic switch 36, respectively; the base, emitter, and collector of the PNP transistor correspond to the control end, input end, and output end of the first electronic switch 36, respectively.

[0032] Taking the NPN transistor and PNP transistor to realize automatic water replenishment and temperature adjustment as an example, the implementation process of the utility model is explained and illustrated. When the liquid level of the annealing water tank is at a high level and the water temperature is higher than the set temperature, that is, the output signal of the liquid level sensor 21 is greater than the output voltage of the first reference voltage source 33, and the output signal of the temperature sensor 22 is greater than the output voltage of the second reference voltage source 34, then the first comparator 38 and the second comparator 39 both output a high level, and the AND gate 35 also outputs a high level. The NPN transistor as the first electronic switch 36 is turned on, and the power supply 100 supplies power to the pumping motor 40 and the fan. The pumping motor 40 pumps away the hot water in the annealing water tank, and at the same time, the external circulation water tank 70 starts to lower the water temperature through the fan. When the liquid level switch is at a low level, That is, the output signal of the liquid level sensor 21 is less than the output voltage of the first reference voltage source 33. Regardless of whether the water temperature of the annealing water tank is higher than the set temperature, the output of the AND gate 35 is low, the NPN transistor as the first electronic switch 36 is cut off, the pumping motor 40 and the fan are powered off, so that the pumping motor 40 stops automatically and the cooling fan stops. At this time, the PNP transistor as the second electronic switch 37 is turned on, and the power supply 100 supplies power to the solenoid valve 81 (normally closed solenoid valve). The solenoid valve 81 automatically opens after being excited, and the cooled cold water is replenished to the annealing water tank, thereby realizing functions such as automatic circulation, automatic cooling, and automatic water replenishment.

[0033] In order to facilitate the placement and removal of the titanium flat bar 90, a slot can be provided on the side wall of the annealing water tank, and the titanium flat bar 90 is inserted into the slot. The distance between the slot and the annealing water tank needs to be smaller than the above-mentioned high liquid level (i.e., the liquid level value corresponding to the output voltage of the first reference voltage source 33).

[0034] When the titanium flat bar 90 is too long, the temperature of the titanium flat bar 90 can be reduced by placing multiple annealing water tanks side by side, for example Figure 1 The result of placing three annealing water tanks side by side is shown in the figure. The three annealing water tanks are respectively recorded as the first annealing water tank 11, the second annealing water tank 12 and the third annealing water tank 13. The bottoms of two adjacent annealing water tanks are connected by a connecting pipe 15. The first water inlet and the second water outlet can be set on any annealing water tank, and of course, they can also be located on different annealing water tanks.

[0035] To facilitate installation and avoid clutter of pipelines, in a preferred embodiment of the utility model, the first pipeline includes a first pipe 50 and a first second pipe 60, one end of the first pipe 50 is connected to the first water outlet, the other end of the first pipe 50 is connected to the water inlet of the pumping motor 40, one end of the first second pipe 60 is connected to the water outlet of the pumping motor 40, and the other end of the first second pipe 60 is connected to the second water inlet.

[0036] The second pipeline includes a 21st pipeline, a 22nd pipeline and a 23rd pipeline. One end of the 21st pipeline is connected to the second water outlet, the other end of the 21st pipeline is connected to one end of the 23rd pipeline through the 22nd pipeline, and the other end of the 23rd pipeline is connected to the first water inlet. The 21st pipeline and the 23rd pipeline are horizontal pipelines, and the 22nd pipeline is a vertical pipeline.

[0037] The first water inlet can be directly set on the annealing water tank, or the annealing water tank can be set as an open structure. The other end of the second third pipe is connected to an elbow 82, and the elbow 82 is located above the open structure. The elbow 82 serves as the first water inlet.

[0038] In other embodiments, a pumping motor may also be provided on the second pipeline to increase the water replenishment rate.

[0039] Finally, it should be noted that the above-mentioned implementation modes are only optional embodiments of the present invention and cannot be used to limit the scope of protection of the present invention. Any non-substantial changes and substitutions made by technicians in this field on the basis of the present invention shall fall within the scope of protection required by the present invention.
