Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0015] like Figure 1-Figure 4 As shown, an inner coil heat-induced vibration heating container includes a container body and a heating coil 18, the middle part of the heating coil 18 is located in the inner cavity of the container body, and the heating coil 18 is a planar spiral structure, the heating coil 18 has a heat medium inlet 7 and a heat medium outlet 10, the heat medium inlet 7 and the heat medium outlet 10 are located on the outside of the container body, and a plurality of joints 26 are also provided on the heating coil 18, and a plurality of direct current tubes 15 are connected to the joints 26, and the direct current tubes 15 are arranged on the inner side of the container body at equal vertical angles, an outflow pipe 17 is provided at the center of the container body, and a connecting pipe 16 is provided between the outflow pipe 17 and the direct current tube 15, the lower end of the outflow pipe 17 is connected to the heating coil 18, and the connecting position of the two is located on the rear side of the heat medium inflow direction of all direct current tubes 15, and a sealing member 19 is provided on the joint 26.

[0016] The sealing member 19 comprises a connecting tube 25, a connecting member 20, a spring 24 and a movable plug 23. The DC tube 15, the joint 26 and the connecting tube 25 are all provided with external threads, and the three are connected by a first nut 21. The connecting tube 25 has a connecting hole 22 with a stepped structure. One end of the connecting member 20 and the DC tube 15 are both located in one end of the connecting tube 25. The spring 24, the movable plug 23 and the joint 26 are all located in the other end of the connecting tube 25. The spring 24 applies a force to the movable plug 23 to block the connecting hole 22. The connecting member 20 is a circular ring structure, and a blocking portion 29 with a cross structure is provided at the center of the movable plug 23. A pressing column 27 is provided at the center of the movable plug 23, and one end of the pressing column 27 is in conflict with the blocking portion 29. A plurality of guide grooves 28 are provided on the outer circle of the connecting member 20. When installing the DC tube 15, first use one of the first nuts 21 to fix the connecting tube 25 on the joint 26. At this time, the spring 24 and the movable plug 23 are in The connecting tube 25 is in the connecting tube 25, and the spring 24 applies an upward force to the movable plug 23, so that the movable plug 23 conflicts with the connecting tube 25. At this time, the connecting hole 22 is closed by the movable plug 23, and the heat medium in the heating coil 18 cannot enter the container body through the connecting hole 22, thereby achieving an automatic sealing effect. At this time, the pressure column 27 is exposed in the connecting tube 25, and then the connecting piece 20 and one end of the direct current tube 15 are inserted into the connecting tube 25. Under the pressure of the connecting piece 20, the pressure column 27 compresses the spring 24 downward, so that the movable plug 23 moves downward synchronously, and the direct current tube 15 and the connecting tube 25 are connected together with another first nut 21, so that the heating coil 18 is connected with the direct current tube 15. When the heat medium flows in the heating coil 18, a part of it can flow from the direct current tube 15 into the outflow pipe 17, and then enter the heating coil 18. In this way, the direct current tube 15 can increase the heat exchange efficiency of the heating container.

[0017] The container body includes a base 2 and a cylinder 1. The base 2 is a hemispherical structure, and a first fixed block 4 is arranged on the base 2, a curved frame 3 is arranged on the cylinder 1, a rotating shaft 5 is arranged between the curved frame 3 and the first fixed block 4, and a fastener is also arranged between the cylinder 1 and the base 2, the fastener includes a second fixed block 14, a T-bolt 13, a third fixed block 12 and a second nut 11, the second fixed block 14 is arranged on the cylinder 1, the third fixed block 12 is arranged on the base 2, and an open groove is also arranged on the third fixed block 12, one end of the T-bolt 13 is rotatably connected to the second fixed block 14, and the other end is located in the open groove and is threadedly connected to the second nut 11, the cylinder 1 and the base 2 are connected and fixed by the T-bolt 13 and the second nut 11, which can achieve a quick release effect, and allow the cylinder 1 to rotate with the rotating shaft 5 as the rotation center, so that the cylinder 1 can be separated from the base 2, so that it is convenient to disassemble and assemble the heating coil 18 and clean the container body.

[0018] Three groups of fasteners are symmetrically arranged at 120° with the axis of the cylinder 1 as the center. A sealing ring is also arranged between the cylinder 1 and the base 2. The three groups of fasteners can firmly connect the cylinder 1 and the base 2 together, and the sealing ring can ensure the sealing between the cylinder 1 and the base 2, thereby achieving a vacuum or sealing effect.

[0019] The base 2 is provided with mounting columns 6 at positions corresponding to the heat medium inlet 7 and the heat medium outlet 10. The mounting columns 6 can conveniently fix the heating coil 18 so that the middle part of the heating coil 18 can be suspended in the base 2. A discharge pipe 8 is provided at the bottom center of the base 2, and a control valve 9 is provided on the discharge pipe 8. The discharge pipe 8 and the control valve 9 can be used to conveniently discharge the raw materials.

[0020] Working principle: The container body is filled with heated raw materials, and the heat medium is introduced from the heat medium inlet 7 of the heating coil 18. After the heat medium enters the heating coil 18, it flows in a spiral manner, which not only increases the heating area and maximizes heat exchange, but also the heating coil 18 is located at the bottom of the container body, which can reduce the heating dead zone and promote convective heat transfer in the container body. In addition, during the flow of the heat medium, it will form heat flow fluid disturbance, centrifugal field force, and solution convection in the heating coil 18, resulting in induced vibration, so that the tube wall of the heating coil 18 is not easy to scale and automatically descale.

[0021] When there is a lot of raw materials in the container body, a direct current pipe 15 and a seal 19 are added and installed on the joint 26, so that part of the heat medium in the heating coil 18 can flow through the direct current pipe 15 to the outflow pipe 17 and then enter the heating coil 18, which can speed up the heat conduction efficiency. When there is less raw materials, after the direct current pipe 15 is removed, the force exerted by the spring 24 on the movable plug 23 can close the connecting hole 22 of the connecting pipe 25, so that the heat medium and the direct current pipe 15 will not mix.
