[0052] Embodiment 2

[0053] Based on the embodiment 1, as Figure 4 and Figure 5As shown in the figure, the embodiment provides a plastic production energy-saving constant temperature water bath device. Different from the embodiment 1, the tank wall of the water bath tank 09 of the embodiment is formed with a sandwich structure of an inner wall 16 and an outer wall 18, and a heat preservation layer 17 is connected between the inner wall 16 and the outer wall 18.

[0054] Compared with the embodiment 1, the advantage of the embodiment is that the heat preservation effect of the inside of the water bath tank 09 can be achieved by installing the heat preservation layer 17 on the tank wall of the water bath tank 09, and the energy dissipation is further reduced.

[0055] Embodiment 3

[0056] Based on the embodiment 2, as shown in the figure, Figure 6 and Figure 7 the embodiment provides a plastic production energy-saving constant temperature water bath device. Different from the embodiment 2, the tank wall of the water bath tank 09 of the embodiment is connected with an electric heating rod 19. Other structural features are completely the same as those of the embodiment 2.

[0057] Compared with the embodiment 2, the advantage of the embodiment is that the electric heating rod 19 is connected on the tank wall of the water bath tank 09, so that the constant temperature water bath device can be heated by starting the heating rod when the connected extruder does not run, and the constant temperature device can be operated at any time.

[0058] Embodiment 4

[0059] Based on the embodiment 3, as shown in the figure, Figure 8 the embodiment provides a plastic production energy-saving constant temperature water bath device. Different from the embodiment 3, the water bath tank 09 of the embodiment is connected with a temperature sensor 22, and the temperature sensor 22, the first water pump 04 and the second water pump 13 are connected with a controller. The water bath tank 09 is connected with a high liquid level detector 21 and a low liquid level detector 20, and the high liquid level detector 21, the low liquid level detector 20 and the second water pump 13 are connected with the controller.

[0060] Specifically, the temperature sensor 22 is used to monitor the temperature value in the water bath tank 09 at any time, and the temperature signal is transmitted to the controller through the temperature sensor 22. If the temperature in the water bath tank 09 is too high and needs to be cooled, the controller controls the second water pump 13 to open, and the cooling water in the second water tank is introduced into the water bath tank 09, so as to realize the cooling treatment of the water bath tank 09, and then the temperature is controlled in the constant temperature water bath range.

[0061] Specifically, the high liquid level detector 21 connected in the water bath tank 09 is used to detect the highest liquid level value. When the liquid level in the water bath tank 09 reaches the highest liquid level value, the high liquid level detector 21 transmits the signal to the controller, and the controller closes the second water pump 13 to avoid continuing to introduce water into the water bath tank 09. When the liquid level in the water bath tank 09 reaches the lowest liquid level value, the low liquid level detector 20 transmits the signal to the controller, and the controller opens the second water pump 13 to supplement water into the water bath tank 09 in time.

[0062] Compared with example 3, the advantages of this example are that the connected temperature sensor 22 can monitor the temperature in the water bath tank 09 at any time. When the temperature in the water bath tank 09 changes, the temperature sensor 22 transmits the signal to the first water pump 04 or the second water pump 13 through the controller, and adjusts the temperature in the water bath tank 09 by introducing hot water or cold water into the water bath tank 09, so as to ensure that the water bath tank 09 is always in a constant temperature state. The high liquid level detector 21 connected in the water bath tank 09 is used to detect the highest liquid level value in the water bath tank 09, so as to avoid the case that too much water is introduced into the water bath tank 09. The low liquid level detector 20 connected in the water bath tank 09 is used to detect the lowest liquid level value in the water bath tank 09, so as to avoid the case that too little water in the water bath tank 09 leads to poor constant temperature effect.

[0063] The above specific embodiments further illustrate the purpose, technical scheme and beneficial effects of the present application. It should be understood that the above description is only a specific embodiment of the present application, and is not used to limit the protection scope of the present application. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
