Description

Technical Field

[0001] The present invention relates to the field of heaters, and in particular to a cross-flux heater and a heating method. Background Art

[0002] In modern industry and everyday life, the demand for heating technology is growing. Traditional heating methods, such as resistance heating and gas heating, suffer from low efficiency, severe energy waste, and uneven heating. With the continuous advancement of technology, magnetic flux heaters have emerged. Magnetic flux heaters generate an alternating magnetic field by passing an alternating current through a specific coil. When the object to be heated is placed in this magnetic field, electromagnetic induction creates eddy currents within the object. As the eddy currents flow through the object, they generate heat due to their electrical resistance, thereby heating the object. This heating method offers advantages such as fast heating speed, high efficiency, and uniform heating. In industrial production, magnetic flux heaters are used in fields such as metal smelting, heat treatment, and plastic molding. In daily life, they are also used in household appliances such as induction cookers.

[0003] However, when the magnetic flux heater in the prior art is used for heating, the object to be heated must be a conductive structure. If a non-conductive object is to be heated, a conductive structure needs to be added around the object, and the non-conductive object is heated by the heated conductive structure to achieve indirect heating. However, this indirect heating only has a good heating effect on the part of the object that is closer to the conductor, while the heating effect is generally poor for the part far away from the conductor, resulting in poor heating uniformity. In addition, when the existing magnetic flux heater heats the fluid, regardless of whether the fluid is a conductor, a pipe needs to be set in the heater, and then the fluid is heated when passing through the pipe. Solids are divided into two cases. If the solid is a conductor, there is no need to set a conductor around it for indirect heating. If the solid is a non-conductor, a conductor needs to be set around the solid. The existing magnetic flux heater can generally only heat fluids or solids alone, and cannot meet the heating needs of solids, fluids, etc., and has poor adaptability.

[0004] Therefore, it is necessary to propose a cross-flux heater and a heating method to solve the above problems. Summary of the Invention

The cylinder 25 is evenly arranged around the inner side of the first conductor cylinder 10. The inner wall of the second conductor cylinder 11 is rotatably connected to a circular shaft 26 corresponding to the cylinder 25, and a conductor plate 24 is fixedly provided on the outer side of one end of the circular shaft 26 away from the cylinder 25.

An arc-shaped guide block 28 is fixedly provided on the inner wall of the cylinder 25 near one end of the circular shaft 26 and is movably guided and engaged with the guide groove 27. Therefore, when the cylinder 25 and the circular shaft 26 are axially displaced, the conductor plate 24 is flipped. The configuration is such that when the second splicing strip 21 and the first splicing interface 30 or the first splicing strip 20 and the second splicing interface 31 are fully plugged in, one end of the conductor plate 24 is aligned with the axis of the first conductor cylinder 10 and the second conductor cylinder 11.

[0051] like Figure 3-Figure 4As shown, in order to adapt to the heating of solids or fluids by moving the first conductor cylinder 10 and the second conductor cylinder 11 closer to or farther from each other, a first driving mechanism for driving the first conductor cylinder 10 and the second conductor cylinder 11 closer to or farther from each other is provided on the inner side of the heater housing 2.

In order to increase the stability of the traction plate 15, a first linear guide 13 corresponding to the traction plate 15 is provided on the inner lower end of the heater housing 2. The lower end of the traction plate 15 is slidably guided and connected to the first linear guide 13.

[0052] like Figure 3-Figure 4 As shown, in order to achieve uniform heating and heating effect of solids or fluids, a second driving mechanism for driving the conductor tube assembly to rotate is provided on the inner side of the heater housing 2, and the second driving mechanism includes a second gear 12 fixedly connected to the outer side of the first conductor cylinder 10 and the second conductor cylinder 11 away from one end. The upper end of the inner side of the heater housing 2 is rotatably connected to the rotating shaft 7, and the two ends of the rotating shaft 7 are symmetrically fixedly connected with first gears 8 that correspond to and mesh with the second gear 12 one by one. One end of the rotating shaft 7 is provided with a first motor 14 for driving the rotating shaft 7 to rotate, so that the first conductor cylinder 10 and the second conductor cylinder 11 rotate as a whole when the rotating shaft 7 rotates. In order to adapt to the rotation, the traction ring 17 is rotatably connected to the first conductor cylinder 10 and the second conductor cylinder 11. Specifically, bearings are fixedly provided on the outer sides of the first conductor cylinder 10 and the second conductor cylinder 11 corresponding to the traction ring 17, and the traction ring 17 is fixed at the bottom of the bearing.

[0053] In addition, if Figure 3-Figure 5 、 Figures 14-18As shown, in order to increase the stability of the solid after passing through the first conductor tube 10 and the second conductor tube 11, positioning components for positioning the object to be heated are provided at both ends of the inner side of the heater shell 2, and the positioning components include positioning rings 9 fixedly arranged at both ends of the inner side of the heater shell 2 and corresponding to the ends away from the first conductor tube 10 and the second conductor tube 11 respectively. The inner side of the positioning ring 9 is evenly surrounded by a notch 37, and a slide groove 38 is provided at the middle part of the inner side of the notch 37. An adjusting arm 36 is movably connected to the inner side of the slide groove 38 along the radial direction of the positioning ring 9. The end of the adjusting arm 36 close to the axis of the positioning ring 9 is rotatably connected to the first roller 35. The side of the traction ring 17 close to the positioning ring 9 is evenly surrounded by a first driving plate 22. The end of the first driving plate 22 close to the positioning ring 9 is fixedly provided with a second driving plate 34 with a thickness smaller than the first driving plate 22, and the connection between the second driving plate 34 and the first driving plate 22 is transitioned through a slope 33. A through groove 42 corresponding to the first driving plate 22 is provided on one side of the adjusting arm 36. A driving plate 22 and a second driving plate 34 are used to be movably connected to the through groove 42.

The end of the guide rod 40 close to the adjusting arm 36 is fixedly connected to the side wall of the end of the adjusting arm 36 away from the axis of the positioning ring 9. In order to reduce friction, a first roller 35 close to the inner side of the through groove 42 is rotatably connected to the first roller 35 of the positioning ring 9. The second roller 43 is used for rolling cooperation with the first drive plate 22, the second drive plate 34 and the slope 33.

A second linear guide rail 41 is provided on the side of the support plate 23 close to the axis of the positioning ring 9. The first drive plate 22 and the second drive plate 34 are slidingly guided in cooperation with the second linear guide rail 41.

[0054] It should be noted that the outer sides of the protective sleeve 5, the positioning ring 9, and the rotating shaft 7 are fixed to the inner wall of the heater housing 2 by a fixing structure. The fixing structure adopts a conventional method, such as a fixing frame, etc., and will not be described in detail.

[0055] In addition, the first motor 14 and the second motor 16 are also electrically connected to the distribution box 1 , and can be powered and started and stopped through the distribution box 1 .

[0056] In some embodiments, a heating method of a cross-flux heater includes the following steps:

[0057] Step 1: When the object to be heated is a fluid, the first drive mechanism controls the first and second conductor cylinders 10, 11 to be completely closed. At this point, the conductor plate 24 flips to align one end with the axis of the first and second conductor cylinders 10, 11 of the fixed cylinder 4. Then, the ends of the first and second conductor cylinders 10, 11 facing away from each other are connected to a pipe and fluid is introduced. The second drive mechanism drives the first and second conductor cylinders 10, 11 to rotate as a whole, and the heating mechanism heats the fluid.

[0058] Step 2: When the object to be heated is a solid, the first drive mechanism controls the first conductor cylinder 10 and the second conductor cylinder 11 to separate, exposing the first splicing interface 30 and the second splicing interface 31. The solid passes through the first conductor cylinder 10 and the second conductor cylinder 11, and the two ends are supported by the positioning assembly. During this period, the second drive mechanism drives the first conductor cylinder 10 and the second conductor cylinder 11 to rotate, and the heating mechanism heats the solid.

[0059] The working principle is:

[0060] During use, if the heated object is a fluid, and regardless of whether the fluid is a conductor, the second motor 16 is controlled to drive the bidirectional screw 6 to rotate, and the bidirectional screw 6 drives the traction ring 17 to move closer through the traction plate 15, and the traction ring 17 drives the first conductor cylinder 10 and the second conductor cylinder 11 to move closer, and then the second splicing strip 21 is completely inserted into the first splicing interface 30, the first splicing strip 20 is completely inserted into the second splicing interface 31, and the sealing strip 29 will completely enter the sealing groove 32, and is further sealed by the graphite strip on the inner wall of the sealing groove 32, and the first conductor cylinder 10 and the second conductor cylinder 11 are completely inserted into the second splicing interface 31. When the body cylinders 11 are close to each other, the cylinder 25 and the circular shaft 26 are also driven to be close to each other, and then the guide block 28 will drive the circular shaft 26 and the conductor plate 24 to rotate as a whole through the action of the guide groove 27, and then the conductor plate 24 is flipped to one end corresponding to the axis of the fixed cylinder 4, and then the pipes are connected to the ends away from each other of the first conductor cylinder 10 and the second conductor cylinder 11 to pass the fluid. During this period, the first motor 14 drives the first gear 8 to rotate through the rotating shaft 7, and the first gear 8 drives the first conductor cylinder 10 and the second conductor cylinder 11 to rotate as a whole through the second gear 12. The distribution box 1 supplies power to the coil 19, and the electric Heating is achieved by magnetic induction, and during this period, the conductor plate 24 stirs the fluid, which can effectively stir the fluid in the conductor tube assembly, break the temperature stratification and concentration gradient in the fluid, and promote the mixing and uniform distribution of the fluid. Uniform fluid distribution means that heat can be more evenly transferred to various parts of the fluid, thereby avoiding local overheating or overcooling. At the same time, stirring the fluid also helps to reduce scaling and deposition on the inner wall and surface of the conductor tube assembly. Moreover, the conductor plate 24 is a conductor and extends to the axial position of the first conductor tube 10 and the second conductor tube 11. Regardless of whether the fluid is a conductor, Both can achieve synchronous heating of the fluid. If the fluid is a conductor, the first conductor cylinder 10, the second conductor cylinder 11, the first splicing bar 20, the second splicing bar 21, the conductor plate 24, and the fluid itself will generate eddy currents, thereby achieving heating of the fluid. If the fluid is a non-conductor, eddy currents are only generated on the first conductor cylinder 10, the second conductor cylinder 11, the first splicing bar 20, the second splicing bar 21, and the conductor plate 24. Therefore, the first conductor cylinder 10, the second conductor cylinder 11, the first splicing bar 20, the second splicing bar 21, and the conductor plate 24 indirectly heat the fluid.

[0061] When the object to be heated is a solid, for example, a common solid to be heated is a pipe or a rod, the second motor 16 is controlled to drive the bidirectional screw 6 to rotate in the opposite direction, and the traction plate 15 and the traction ring 17 drive the first conductor cylinder 10 and the second conductor cylinder 11 to move away from each other, so that the first splicing strip 20 is partially separated from the second splicing interface 31, and the second splicing strip 21 is partially separated from the first splicing interface 30. At this time, the first splicing interface 30 and the second splicing interface 31 are both exposed. Due to the displacement of the first conductor cylinder 10 and the second conductor cylinder 11, the cylinder 25 and the circular shaft 26 are synchronously displaced away from each other, and then the conductor plate 24 is reversed. The first conductor tube 10 and the second conductor tube 11 are flipped and hidden to fit inside the first splicing strip 20 and the second splicing strip 21 to avoid obstruction to the solid. In addition, when the first conductor tube 10 and the second conductor tube 11 are displaced away from each other, the traction ring 17 will also drive the first drive plate 22 and the second drive plate 34 to move toward the direction of the positioning ring 9, and then the solid passes through the first conductor tube 10 and the second conductor tube 11. Initially, the second drive plate 34 rolls with the second roller 43. As the traction ring 17 approaches the positioning ring 9, the second roller 43 rolls with the slope 33. At this time, the adjustment arm 36 is driven to move toward the axial direction of the positioning ring 9, and the spring 39 is compressed. When the second roller 43 and the first drive plate 22 are rolling in cooperation, the adjustment arm 36 remains stationary. At this time, the space surrounded by the multiple first rollers 35 is used for the solid to pass through. The first roller 35 positions the solid in the center and facilitates the displacement of the solid. During this period, the second conductor cylinder 11 and the entire second conductor cylinder 11 are also driven to rotate by the second drive mechanism. The distribution box 1 supplies power to the coil 19, and electromagnetic induction is used to achieve heating. When the solid is a conductor, the first conductor cylinder 10, the second conductor cylinder 11, the first splicing strip 20, the second splicing strip 21 and the solid itself will generate eddy currents, and the exposed first splicing interface 30 and the second splicing interface 31 can allow part of the electromagnetic field to penetrate, reducing shielding, and can heat the solid evenly and efficiently in conjunction with rotation. If the solid is a non-conductor, eddy currents will be generated on the first conductor tube 10, the second conductor tube 11, the first splicing strip 20, and the second splicing strip 21. Therefore, in conjunction with rotation, the first conductor tube 10, the second conductor tube 11, the first splicing strip 20, and the second splicing strip 21 can heat the solid evenly. The device can be used for solid heating and can also adapt to the heating of fluids. Whether it is a conductor or a non-conductor, it can achieve uniform and efficient heating. The heating method is adjusted through electric control, and it is easy to use.
