[0022] In this embodiment, Figure 2 and Figure 3 As shown, the driving assembly includes a base 10, a stepping motor 11, two support plates 12, a connecting shaft 14, and a gear 15; The end of the base 10 is fixedly connected to the outer wall of the cylinder 3; The stepper motor 11 is fixedly connected to the top of the base 10; The ends of the two support plates 12 are fixedly connected to the outer wall of the cylinder 3; The ends of the connecting shaft 14 are respectively rotatably connected to the support plates 12 , and the ends of the connecting shaft 14 are fixedly connected to the stepping motor 11 ; The gear 15 is fixedly connected to the outer wall of the connecting shaft 14 , and the gear 15 is meshed with the gear plate 17 .

[0025] The slide groove 13 on the support plate 12 is slidably connected to the lifting plate 16, providing guidance for the movement of the lifting plate 16, ensuring that the lifting plate 16 will not deviate or shake during the movement, making the water injection pipe 18 rise and fall more stable and accurate, further improving the accuracy of water injection height adjustment.

[0026] In this embodiment, Figure 4 As shown, an oil outlet pipe 21 is slidably connected to the inner wall of another connecting sleeve 19 , the end of the oil outlet pipe 21 passes through the first sealing ring 20 and is slidably connected thereto, and a hose 22 is fixedly connected to the bottom of the oil outlet pipe 21 .

[0029] The oil delivery pump 28 on the frame 27 is connected to the oil outlet pipe 21 and can pump out the liquid in the inner tube 7.

[0030] In this embodiment, Figure 4 As shown, the end of the hose 22 is fixedly connected to the float 23, and the end of the hose 22 extends to the bottom of the float 23. Two sliders 24 are fixedly connected to the outer wall of the float 23. The inner wall of the slider 24 is slidably connected to a slide rod 25.

[0031] The float 23 slides on the slide rod 25 through the slider 24, and can move up and down as the liquid level in the inner tube 7 changes, ensuring that the hose 22 is always on the liquid surface, the extracted liquid is relatively pure, and precipitated impurities are avoided, thereby ensuring the quality of the liquid; the limiting ball 26 can prevent the float 23 from separating from the slide rod 25, thereby ensuring the stability of the structure.

[0032] In this embodiment, Figure 1 As shown, the heat conduction heating device further includes a base 1 , a plurality of support arms 2 are fixedly connected to the top of the base 1 , and the ends of the support arms 2 are respectively fixedly connected to the outer wall of the cylinder 3 .

[0033] The base 1 is fixedly connected to the cylinder 3 via the support arm 2, providing stable support for the entire device.

[0034] In this embodiment, Figure 2 As shown, the outer wall of the cylinder 3 is fixedly connected to the insulation layer 4, the bottom of the cylinder 3 is fixedly connected to the heater 5, and the output end of the heater 5 is fixedly connected to multiple heat-conducting rods 6, which pass through the inner cylinder 7 and extend into the interior thereof.

[0035] The insulation layer 4 on the outer wall of the cylinder 3 can effectively reduce heat loss to the outside and improve the thermal efficiency of the heat conduction heating device; the heater 5 heats the liquid in the inner cylinder 7 through the heat conducting rod 6 to quickly increase the temperature of the liquid.

[0036] In this embodiment, Figure 5-Figure 8 As shown, the outer wall of the cylinder 3 is fixedly connected to a liquid inlet pipe 29, the end of the liquid inlet pipe 29 passes through the inner cylinder 7 and extends into the interior thereof, the outer wall of the liquid inlet pipe 29 is fixedly connected to a valve 30, the outer end of the liquid inlet pipe 29 is fixedly connected to a connecting pipe 31, the end of the connecting pipe 31 is fixedly connected to a ball sleeve 32, the outer wall of the ball sleeve 32 is fixedly connected to a joint 33, the top of the outer wall of the ball sleeve 32 is fixedly connected to a cleaning port 34, and the top of the cleaning port 34 is threadedly connected to a sealing cover 35.

[0037] A drain port 36 is provided on the inner wall of the ball sleeve 32, and two annular grooves 3601 are provided on the inner wall of the ball sleeve 32. A fixing ring 37 is provided on the inner wall of the ball sleeve 32, and a plurality of protrusions 38 are fixedly connected to the outer wall of the fixing ring 37. A filter screen 39 is fixedly connected to both ends of the fixing ring 37, and an extension sleeve 41 is fixedly connected to both ends of the filter screen 39. The extension sleeves 41 are rotatably connected to the inner walls of the ball sleeve 32 respectively, and the outer walls of the extension sleeves 41 are fixedly connected to the second sealing ring 40, and the second sealing ring 40 is rotatably connected to the annular groove 3601.

[0038] The arrangement of the liquid inlet pipe 29, the connecting pipe 31, the ball sleeve 32, and the valve 30 can control the inlet and outlet of the liquid; the cleaning port 34 and the sealing cover 35 on the ball sleeve 32 facilitate internal cleaning and maintenance, ensuring the smooth and clean flow of the liquid inlet channel and extending the service life of the device; The fixed ring 37, protrusion 38, filter screen 39 and other structures in the ball sleeve 32 can filter the liquid entering the inner tube 7, remove impurities, and ensure the purity of the liquid in the inner tube 7; the extension sleeve 41 and the second sealing ring 40 cooperate with the annular groove 3601 to enable the filter screen 39 to rotate, making it easier to clean and replace the filter screen 39, thereby improving the filtering effect and convenience of maintenance.

[0039] Working principle: When in use, the mixed liquid enters the inner cylinder 7 through the joint 33, the ball sleeve 32 and the connecting pipe 31. The filter screen 39 in the ball sleeve 32 can filter the liquid. When the filter screen 39 needs to be cleaned, the sealing cover 35 is opened, and the filter screen 39 is driven to rotate by pushing the protrusion 38 on the outer wall of the fixing ring 37. The filter screen 39 rotates toward the part of the joint 33 to the cleaning port 34, which makes it convenient for the operator to clean impurities on the filter screen 39 through the cleaning port 34.

[0040] The filtered mixed liquid can enter the inner tube 7 again through the filter screen 39 at the end of the connecting tube 31, and can also enter the inner tube 7 through the drain port 36 and the connecting tube 31 to achieve rapid liquid injection.

[0041] The heater 5 at the bottom of the cylinder 3 heats the liquid in the inner cylinder 7 through the heat conducting rod 6 to prevent the oil layer from solidifying.

[0042] The heat-insulating layer 4 on the outer wall of the cylinder 3 can reduce heat loss.

[0043] Start the stepper motor 11, which drives the connecting shaft 14 to rotate, and the gear 15 on the connecting shaft 14 rotates accordingly. Since the gear 15 is engaged with the tooth plate 17, it drives the lifting plate 16 fixedly connected to the tooth plate 17 to move along the axial direction of the cylinder 3, thereby realizing the lifting and lowering of the water injection pipe 18 in the connecting sleeve 19, and adjusting the height of the water injection port so that the water injection port is close to the bottom of the oil surface for water injection, reducing the resistance during water injection and saving energy consumption of the water pump.

[0044] When water is injected, the water surface pushes the oil level up, causing the oil level to contact the float 23, starting the oil pump 28, and the liquid flows out from the oil outlet pipe 21. The hose 22 at the bottom of the oil outlet pipe 21 is connected to the float 23. The float 23 can slide on the slide rod 25 as the liquid level in the inner tube 7 changes, always staying on the liquid surface, ensuring that the relatively pure liquid in the upper layer is extracted.

[0045] It should be noted that the terms "comprises", "includes" or any other variations thereof are intended to cover non-exclusive inclusion, so that a process, method, article or apparatus that includes a series of elements includes not only those elements, but also includes other elements not explicitly listed, or also includes elements that are inherent to such process, method, article or apparatus.
