DETAILED DESCRIPTION

[0021] In order to better understand the purpose, structure and function of the utility model, the following is a further detailed description of a device for heating a fluid storage tank of the utility model in conjunction with the accompanying drawings.

[0022] like Figure 1 As shown, the fluid storage tank 10 comprises a bottom plate 101, a side plate 102 disposed on the bottom plate 101 and extending upward, the side plate 102 and the bottom plate 101 together define a top opening, and the inside has a structure for accommodating a chamber 103. A cover plate 104 is disposed at the bottom plate opening, and the cover plate 104 is sealedly connected to the side plate 102 to seal the chamber 103.

[0023] In this way, the bottom plate 101, the side plate 102 and the cover plate 104 can together form a circumferentially sealed chamber 103 for containing fluid. It should be noted that these structures of the fluid storage tank 10 are well known to those skilled in the art.

[0024] Figure 2 The overall structure of the device 100 for heating a fluid storage tank according to the present invention is schematically shown. Figure 2 In the illustrated embodiment, the device 100 for heating a fluid storage tank comprises a heating mechanism 1 disposed on the fluid storage tank 10 , wherein the heating mechanism 1 extends into the chamber 103 for contacting the fluid in the chamber 103 .

[0025] At the same time, the heating mechanism 1 is configured to be turned on in a selectable manner. In this way, the heating mechanism 1 can heat the fluid in the fluid storage tank 10 in a selectable manner. Therefore, when the external environment temperature is low, the heating mechanism 1 can be turned on to avoid condensation of the fluid in the cavity 103. It should be noted that the heating mechanism 1 is made of a material with thermal conductivity.

[0026] In one embodiment, Figure 2 As shown, the heating mechanism 1 includes a first heating tube 11 and a second heating tube 12 respectively arranged on the side plate 102 and extending into the cavity 103. The first heating tube 11 and the second heating tube 12 are connected to each other at the ends of the cavity 103, thereby forming a channel for the movement of the heating medium. In the utility model, the heating mechanism 1 is arranged as a "U"-shaped structure for the flow of the heating medium.

[0027] At the same time, if Figure 2As shown, the device 100 also includes a heating mechanism 2 for continuously providing heat to the heating mechanism 1. In this embodiment, the heating mechanism 2 includes a heating tank 21 configured to store a heating medium and capable of heating the heating medium, and a liquid inlet pipe 22 for interconnecting the heating tank 21 with the first heating tube 11. In this way, when it is necessary to heat the fluid in the cavity 103, the heating tank 21 is started so that the heating tank 21 can heat the heating medium in the heating tank 21 to a suitable temperature.

[0028] Then, a force is applied to the heating medium in the heating tank 21 , so that the heating medium moves along the liquid inlet pipe 22 into the first heating tube 11 , and moves along the “U”-shaped channel formed by the first heating tube 11 and the second heating tube 12 .

[0029] In this process, the heat carried by the heating medium will be transferred to the first heating tube 11 and the second heating tube 12 by heat transfer, and the first heating tube 11 and the second heating tube 12 will be heated until the temperature of the first heating tube 11 and the second heating tube 12 is higher than the temperature of the fluid in the cavity 103. At this time, the heat carried by the first heating tube 11 and the second heating tube 12 will be transferred to the fluid by heat transfer, thereby heating the fluid. In this way, condensation of the fluid in the cavity 103 is avoided.

[0030] In one embodiment, Figure 2 As shown, the heating mechanism 2 further includes a liquid return pipe 23, and the liquid return pipe 23 is used to connect the heating tank 21 with the second heating tube 12. In this way, the heating medium moving along the first heating tube 11 and the second heating tube 12 can move into the heating tank 21 again along the liquid return pipe 23. Thus, heat circulation between the heating mechanism 2 and the heating mechanism 1 is achieved, so that the heating mechanism 2 can continuously transfer heat to the heating mechanism 1, thereby continuously heating the fluid in the cavity 103.

[0031] In this arrangement, when in use, the first heating tube 11 and the second heating tube 12 are respectively fixed on the side wall 102 of the fluid storage tank 10, and the first heating tube 11 and the second heating tube 13 are respectively extended into the cavity 103 and contact with the fluid in the cavity 103. At the same time, the ends of the first heating tube 11 and the second heating tube 12 located in the cavity 103 are connected to each other, so that the first heating tube 11 and the second heating tube 12 together form a "U"-shaped channel for the movement of the heating medium.

[0032] Then, the first heating tube 11 is connected to the heating tank 21 through the liquid inlet tube 22 , and the second heating tube 12 is connected to the heating tank 21 through the liquid return tube 23 .

[0033] When the fluid in the cavity 103 needs to be heated, the heating tank 21 is started so that the heating tank 21 heats the heating medium in the heating tank 21 to a suitable temperature.

[0034] Then, a force is applied to the heating medium in the heating mechanism 2 so that the heating medium can move along the liquid inlet pipe 22 into the first heating tube 11 and move along the “U”-shaped channel formed by the first heating tube 11 and the second heating tube 12 .

[0035] In this process, the heat carried by the heating medium will be transferred to the first heating tube 11 and the second heating tube 12 by heat transfer, and the first heating tube 11 and the second heating tube 12 will be heated until the temperature of the first heating tube 11 and the second heating tube 12 is higher than the temperature of the fluid in the cavity 103. At this time, the heat carried by the first heating tube 11 and the second heating tube 12 will be transferred to the fluid by heat transfer, thereby heating the fluid.

[0036] At the same time, as the heating medium continuously enters the first heating tube 11 along the liquid inlet tube 22, the heating medium moves along the second heating tube 12 into the liquid return tube 23, and moves along the liquid return tube 23 into the heating tank 21 again, and the heating medium is heated again by the heating tank 21. Thus, heat circulation between the heating mechanism 2 and the heating mechanism 1 can be achieved, so that the heating mechanism 2 can continuously transfer heat to the heating mechanism 1, thereby continuously heating the fluid in the cavity 103 and preventing the fluid in the cavity 103 from condensing.

[0037] In one embodiment, Figure 2 As shown, the device 100 further includes a negative pressure mechanism 3 connected to the heating tank 21, and the negative pressure mechanism 3 is configured as any structure capable of conveying the heating medium in the heating tank 21 to the liquid inlet pipe 22. In this embodiment, the negative pressure mechanism 3 is configured as a water pump.

[0038] In this embodiment, if Figure 2 As shown, the negative pressure mechanism 3 is arranged in the heating tank 21, and the negative pressure mechanism 3 is connected to the free end of the liquid return pipe 23 to provide a negative pressure force. In this arrangement, when it is necessary to transport the heating medium toward the heating mechanism 1, the negative pressure mechanism 3 is started, and the negative pressure mechanism 3 will continuously generate a negative pressure force along the liquid return pipe 23.

[0039] In this process, the negative pressure force will be transmitted to the heating tank 21 along the liquid return pipe 23, the heating mechanism 1 and the liquid inlet pipe 22, and the heating medium in the heating tank 21 will move along the liquid inlet pipe 22, the heating mechanism 1 and the liquid return pipe 23. In this way, the heating of the fluid is completed. In addition, the heat can be transported to the heating mechanism 1 or stopped by controlling the opening or closing of the negative pressure mechanism 3.

[0040] In one embodiment, Figure 2 As shown, a first valve 111 and a second valve 121 are respectively arranged on the first heating tube 11 and the second heating tube 12 located outside the fluid storage tank 10. The first valve 111 and the second valve 121 are respectively configured to selectively open the passages formed inside the first heating tube 11 and the second heating tube 12. In this arrangement, the movement path of the heating medium can be opened or disconnected by opening or closing the first valve 111 and the second valve 121.

[0041] In this arrangement, when in use, the heating mechanism 1 is arranged on the fluid storage tank 10, and the heating mechanism 1 is extended into the cavity 103. At the same time, the first heating tube 11 is connected to the heating tank 21 through the liquid inlet tube 22, and the second heating tube 12 is connected to the heating tank 21 through the liquid return tube 23. In addition, a negative pressure mechanism 3 is also arranged at the free end of the second heating tube 12.

[0042] When the fluid in the cavity 103 needs to be heated, the first valve 111 and the second valve 121 are opened. At the same time, the negative pressure mechanism 3 is started, so that the negative pressure mechanism 3 applies a negative pressure force to the heating medium in the heating mechanism 2, so that the heating medium moves along the liquid inlet pipe 22 into the heating mechanism 1, and moves along the "U"-shaped channel formed by the heating mechanism 1.

[0043] In this process, the heat carried by the heating medium will be transferred to the first heating tube 11 and the second heating tube 12 by heat transfer, and the first heating tube 11 and the second heating tube 12 will be heated until the temperature of the first heating tube 11 and the second heating tube 12 is higher than the temperature of the fluid in the cavity 103. At this time, the heat carried by the first heating tube 11 and the second heating tube 12 will be transferred to the fluid by heat transfer, thereby heating the fluid.

[0044] At the same time, as the heating medium is continuously transported into the heating mechanism 1, the heating medium will move again into the heating tank 21 along the liquid return pipe 23. Thus, heat circulation between the heating mechanism 2 and the heating mechanism 1 can be achieved, so that the heating medium in the heating mechanism 2 can continuously transfer heat to the heating mechanism 1, thereby continuously heating the fluid in the cavity 103 and preventing the fluid in the cavity 103 from condensing.

[0045] When the heating is completed, the negative pressure mechanism 3 is closed so that the heating medium cannot move into the liquid inlet pipe 22, thereby stopping the heating of the fluid. However, the first valve 111 or the second valve 121 can also be closed so that the heating medium cannot circulate between the heating mechanism 1 and the heat supply mechanism 2, thereby stopping the heating of the fluid. In this way, the heating of the fluid is completed.

[0046] In one embodiment, Figure 2 As shown, the device 100 further includes a compensation mechanism 4 for replenishing the heating medium into the heating tank 21. In this embodiment, the compensation mechanism 4 includes a compensation tank 41 for containing the heating medium, and a liquid adding pipe 42 for connecting the compensation tank 41 with the heating tank 21. In this way, when the negative pressure mechanism 3 is activated, the force generated by the negative pressure mechanism 3 can be transmitted to the compensation tank 41 along the liquid adding pipe 42.

[0047] Under this arrangement, when the volume of the heating medium in the heat supply mechanism 2 decreases, the heating medium in the heating tank 4 can continuously move along the liquid adding pipe 41 into the heating tank 21 , thereby replenishing the volume of the heating medium in the heating tank 21 .

[0048] The operation of the device 100 for heating a fluid storage tank according to the present invention is as follows.

[0049] First, the heating mechanism 1 is arranged on the fluid storage tank 10, and the heating mechanism 1 is extended into the cavity 103. At the same time, the first heating tube 11 is connected to the heating tank 21 through the liquid inlet tube 22, and the second heating tube 12 is connected to the heating tank 21 through the liquid return tube 23. In addition, a negative pressure mechanism 3 is arranged at the free end of the second heating tube 12 in the heating tank 21. In addition, the heating tank 21 and the compensation tank 41 are connected to each other through the liquid adding tube 42.

[0050] When the fluid in the cavity 103 needs to be heated, the first valve 111 and the second valve 121 are opened. At the same time, the negative pressure mechanism 3 is started, so that the negative pressure mechanism 3 applies a force to the heating medium in the heating tank 21, and the heating medium moves along the liquid inlet pipe 22 into the first heating tube 11, and moves along the "U"-shaped channel formed by the first heating tube 11 and the second heating tube 12.

[0051] In this process, the heat carried by the heating medium will be transferred to the first heating tube 11 and the second heating tube 12 by heat transfer, and the first heating tube 11 and the second heating tube 12 will be heated until the temperature of the first heating tube 11 and the second heating tube 12 is higher than the temperature of the fluid in the cavity 103. At this time, the heat carried by the first heating tube 11 and the second heating tube 12 will be transferred to the fluid by heat transfer, thereby heating the fluid.

[0052] At the same time, as the negative pressure mechanism 3 continuously transports the heating medium toward the liquid inlet pipe 22, the heating medium will move along the second heating pipe 12 into the liquid return pipe 23, and then move along the liquid return pipe 23 into the heating mechanism 2 again. Thus, heat circulation between the heating mechanism 2 and the heating mechanism 1 can be achieved, so that the heating medium in the heating mechanism 2 can continuously transport heat toward the heating mechanism 1, thereby continuously heating the fluid in the cavity 103 and preventing the fluid in the cavity 103 from condensing.

[0053] When the heating is completed, the negative pressure mechanism 3 is closed so that the heating medium cannot move into the liquid inlet pipe 22, thereby stopping the heating of the fluid. However, the first valve 111 or the second valve 121 can also be closed so that the heating medium cannot circulate between the heating mechanism 1 and the heat supply mechanism 2, thereby stopping the heating of the fluid. In this way, the heating of the fluid is completed.

[0054] In addition, when the volume of the heating medium in the heating mechanism 2 decreases, the heating medium in the heating tank 4 can continuously move along the liquid adding pipe 41 to the heating mechanism 2 , thereby replenishing the volume of the heating medium in the heating mechanism 2 .

In addition, under the teachings of the present invention, these features and embodiments may be modified to adapt to specific circumstances and materials without departing from the spirit and scope of the present invention.
