[0021] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.

[0022] Embodiment 1

[0023] Please refer to the attached Figure 1 , a drawing oil indirect heating device, including:

[0024] A drawing oil container 1, a heating component 2, a temperature monitoring component 4 and a control console. The heating component 2 includes a heating container 20, a heating element 21 and an indirect heating medium 22. The drawing oil container 1 is fixedly connected to the heating container 20. The indirect heating medium 22 is located between the drawing oil container 1 and the heating container 20. The heating element 21 is located in the heating container 20, contacts the heating medium 22, and the heating element 21 is circuit-connected to the control console. The temperature monitoring component 4 is located in the drawing oil container 1 and is circuit-connected to the control console;

[0025] During specific use, the indirect heating medium 22 is filled in the heating container 20 in advance. Considering cost issues, water is used as the heating medium in the present invention. The heating element 21 in the heating container 20 is controlled by the temperature monitoring component 4 installed in the drawing oil container 1 and the control console. For example, when the temperature monitoring component 4 monitors that the temperature of the drawing oil in the drawing oil container 1 is lower than a certain temperature, the heating element 21 is turned on through the control console to heat the indirect heating medium 22, and the indirect electric heating of the drawing oil container 1 is completed through the indirect heating medium 22. Until the temperature monitoring component 4 monitors that the temperature of the drawing oil in the drawing oil container 1 rises to a certain temperature, the heating element 21 is turned off through the control console, and it circulates intermittently. By regulating the temperature of the drawing oil, the viscosity of the drawing oil is ensured to be within the applicable range. It should be noted that different drawing oils have different critical point temperatures.

[0026] Specifically, the heating container 20 includes a fixedly connected outer shell 200 and an inner shell 201. A heat preservation cavity 202 is formed between the outer shell 200 and the inner shell 201, and the heat preservation cavity 202 is filled with a heat preservation gas; considering that heat may escape during the heating process of the indirect heating medium 22, in order to improve the utilization of the heat of the indirect heating medium 22, the outer shell 200 and the inner shell 201 are provided, and the heat preservation cavity 202 located between them is established as a heat preservation layer. It should be noted that pre-filled argon or carbon dioxide can be used as the heat preservation gas, or no special heat preservation gas can be pre-filled, and air can be used as the heat preservation gas.

[0027] Example Two

[0028] Please refer to the attached Figures 2-4

[0029] Specifically, the heating component 2 includes a circulation pipeline 23 and an external circulation heating component 3. The circulation pipeline 23 is arranged in a zigzag shape in the drawing oil container 1, and both ends of the circulation pipeline 23 are fixedly connected to the external circulation heating component 3 respectively;

[0030] In order to further improve the heating effect on the drawing oil, the circulation pipeline 23 and the external circulation heating component 3 are adopted. By guiding the heated water into the circulation pipeline 23 and directly arranging the circulation pipeline 23 in the drawing oil container 1, the heating effect of the drawing oil is improved. The zigzag arrangement can expand the contact area between the circulation pipeline 23 and the drawing oil, further improving the heating effect.

[0031] Specifically, the external circulation heating component 3 includes an external box body 30, a circulation pump 31 and a water volume control component 32. A partition plate 302 is provided in the external box body 30 to divide it into a water storage chamber 300 and a heating chamber 301. A water falling hole 3020 is provided on the partition plate 302. The water volume control component 32 is located in the heating chamber 301 and is fixedly connected to the partition plate 302. The circulation pump 31 is located in the heating chamber 301. One end of the circulation pipeline 23 passes through the wall of the water storage chamber 300 and is fixedly connected to it, and one end passes through the wall of the heating chamber 301 and is detachably connected to the circulation pump 31; Since the heating process of the drawing oil is intermittent circulation heating rather than long-time circulation heating, the external box body 30 is internally divided by the partition plate 302 to form a water storage chamber 300 and a heating chamber. The water storage chamber 300 is used to store the return water in the circulation pipeline 23, and the heating chamber 301 is used to heat the incoming water. The setting of separating the incoming water and the return water avoids the mixing of the return water and the incoming water during the water circulation process, and further avoids the situation that the temperature of the incoming water becomes lower and lower due to the mixing of the return water and the incoming water. The setting of the water volume control component 32 is to temporarily protect the heated incoming water during the water circulation process, that is, when most of a single circulation is not completed, the return water cannot be mixed with the incoming water.

[0032] Specifically, the water volume control component 32 includes a water sealing plate 320, an inner sleeve 321, an outer sleeve 322, a sliding plate 323, a floating block 324, and a spring 325. The lower end of the outer sleeve 322 is fixedly connected to the floating block 324. The sliding plate 323 is located inside the outer sleeve 322. One end of the inner sleeve 321 is fixedly connected to the water sealing plate 320, and the other end passes through the top wall of the outer sleeve 322 and is fixedly connected to the sliding plate 323. The inner sleeve 321 is slidably connected to the outer sleeve 322. The spring 325 is located inside the outer sleeve 322, with one end fixedly connected to the bottom wall of the outer sleeve 322 and the other end fixedly connected to the sliding plate 323. By means of the slidable distance between the inner sleeve 321 and the outer sleeve 322, it is ensured that the return water and the incoming water do not mix during the water circulation process. When the circulation pump 31 is turned on, the water sealing plate 320 is located at the position of the water dropping hole 3020. At this time, the return water in the water storage cavity 300 cannot enter the heating cavity 301. Under the action of the floating block 324, the sliding plate 323 is located at the end close to the floating block 324, and at this time the spring 325 is in a compressed state. When the circulation pump 31 is turned on, the incoming water in the heating cavity 301 starts to enter the circulation pipeline 23, and the water with a lower temperature in the circulation pipeline 23 is discharged into the water storage cavity 300. During this process, the water level in the heating cavity 301 decreases, the position of the floating block 324 drops, and it drives the outer sleeve 322 to move downward, continuously reducing the compression of the spring 325 by the outer sleeve 322. During the process of the spring 325 returning to its normal state, the position of the water sealing plate 320 remains unchanged. During this process, the hot water in the heating cavity 301 continuously enters the circulation pipeline 23, and the return water does not enter the heating cavity 301. After the spring 325 is in its normal state, the floating block 324 continues to move down with the water level. At this time, the water sealing plate 320 and the inner sleeve 321, under the action of their own gravity, are separated from the water dropping hole 3020, and the return water starts to enter the heating cavity 301. At this time, most of the cold water in the circulation pipeline 23 has been replaced by the heated hot water. By combining the use of the temperature monitoring component 4 and the control console, the circulation pump 31 is turned off to prevent the unheated mixed water from entering the circulation pipeline 23. At the same time, as the water in the water storage cavity 300 enters the heating cavity 301, the water level in the heating cavity 301 starts to rise, and the floating block 324 also drives the outer sleeve 322 to rise. During this process, first, the outer sleeve 322 compresses the spring 325, and only after the spring 325 is compressed does it drive the inner sleeve 321 and the water sealing plate 320 to move upward until the water sealing plate 320 comes into contact with the water dropping hole 3020 again, completing the entire single cycle. During the entire single cycle, when the hot water enters the circulation pipeline 23, the return water in the water storage cavity 300 does not mix with the heating cavity 301, indirectly improving the utilization rate of the hot water.

[0033] Preferably, the floating block 324 is provided with at least one set of position limiting rods 3240 that match it. One end of the position limiting rod 3240 is fixedly connected to the bottom wall of the heating chamber 301, and the other end passes through the floating block 324 and is slidably connected to it. In order to prevent the floating block 324 from being positionally skewed during the process of floating up and down with the water level in the heating chamber 301, which may cause the water sealing plate 320 to fail to contact the water dropping hole 3020, the position limiting rod 3240 is provided to lock the position of the floating block 324. Although one set can also complete the position limitation, considering that the floating block 324 may rotate in place, it is more reliable to use two sets of position limiting rods 3240.

[0034] Specifically, the heating element 21 is located in the heating chamber 301, and the heating element 21 is electrically connected to the control console. Considering that the heating element 21 is located in the heating chamber 301 and heating only starts when the water level in the heating chamber 301 reaches a certain height, as long as the heating element 21 does not come into contact with the water volume control assembly 32 and the circulation pump 31, vertical installation can also be considered.

[0035] Specifically, the circulation pipeline 23 is made of a metal material. The circulation pipeline 23 is an important component for conducting heat, so it needs to be made of a metal material. Among them, copper pipes have the best heat conduction efficiency.

[0036] The above is only the preferred specific implementation manner of the present utility model, but the protection scope of the present utility model is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present utility model, according to the technical solution of the present utility model and its inventive concept, makes equivalent substitutions or changes, and all should be covered by the protection scope of the present utility model.
