[0023] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0024] Please see Figures 1-5This utility model provides a technical solution: a material heater, including a mounting frame 1 and a reactor body 2 penetrating the top of the mounting frame 1. A turntable 3 penetrates the center of the top of the reactor body 2, and a vaporized material conveying pipe 4 penetrates the top of the turntable 3. The vaporized material conveying pipe 4 is located at the center of the turntable 3 and is fixedly connected to the turntable 3. When the turntable 3 rotates, it can drive the vaporized material conveying pipe 4 to rotate. A drive assembly 9 is installed on the outside of the turntable 3 and on the top of the reactor body 2. A material recovery assembly 7 is installed on one side of the reactor body 2. The bottom end of the vaporized material conveying pipe 4 extends into the reactor body. Inside the reactor body 2, at the bottom of the four sides of the vaporized material conveying pipe 4, there are exhaust pipes 5. The four exhaust pipes 5 are installed in a staggered manner, so that when the vaporized material conveying pipe 4 rotates and drives the four exhaust pipes 5 to rotate, the liquid material inside the reactor body 2 can be stirred and mixed. The top of each exhaust pipe 5 is uniformly connected to a first one-way valve 6 from left to right. The top of the vaporized material conveying pipe 4 is connected to an external gas pipe through a rotary joint. The top of the other side of the reactor body 2 is connected to an inlet pipe 8, and the bottom of the reactor body 2 is connected to an outlet pipe 10. Solenoid valves are installed on both the inlet pipe 8 and the outlet pipe 10.

[0025] Please see Figure 2 and Figure 5 The material recovery assembly 7 includes four connecting seats 71, a shell-and-tube heat exchanger 72, and an air pump 76. The four connecting seats 71 are fixedly installed around the top of the inner wall of the reactor body 2. The shell-and-tube heat exchanger 72 is fixedly installed on one side of the reactor body 2. The air pump 76 is fixedly installed on one side of the reactor body 2 and located directly above the shell-and-tube heat exchanger 72. The shell-and-tube heat exchanger 72 consists of a bundle of many parallel tubes. The heating medium (such as steam, hot water, heat transfer oil, etc.) flows in the tube side, and the heated gas flows in the shell side, and heat is transferred through the tube wall. With a robust structure and strong adaptability, it can be used in various high-temperature, high-pressure and corrosive media applications. It is widely used in gas heating in chemical, petroleum and other industries. The shell and tube heat exchanger 72 is connected to an external power supply and is equipped with a power control switch. An annular pipe 73 runs through the four connecting seats 71. A second one-way valve 74 is evenly connected to the bottom of the annular pipe 73. An exhaust pipe 75 is connected to one side of the annular pipe 73. One end of the exhaust pipe 75 passes through the reactor body 2 and extends to the air inlet of the air pump 76. The air pump 76 is connected to an external power supply and is equipped with a power control switch. An exhaust pipe 77 is connected between the air outlet of the air pump 76 and the air inlet of the shell and tube heat exchanger 72. The air outlet of the shell and tube heat exchanger 72 is connected to a connecting pipe 78. One end of the connecting pipe 78 passes through the top of the mounting frame 1 and the bottom of the reactor body 2 in sequence and extends to the bottom of the vaporized material conveying pipe 4.

[0026] Please see Figure 2 and Figure 5One end of the connecting pipe 78 is rotatably connected to the bottom end of the vaporized material conveying pipe 4 via a rotary joint. The rotary joint generally consists of a shell, a mandrel, and seals. The mandrel is fixedly connected to one of the pipes, and the shell is connected to the other pipe. The mandrel can rotate within the shell. Through a special sealing structure, it is ensured that the medium (such as liquid or gas) in the pipe will not leak during rotation, thus realizing the connection and rotation functions between the pipes. The rotary joint ensures normal connection between the connecting pipe 78 and the vaporized material conveying pipe 4. A one-way solenoid valve is installed on the pipe surface of the connecting pipe 78 and outside the reactor body 2. A one-way solenoid valve typically consists of a solenoid coil, valve core, spring, and valve body. When the solenoid coil is energized, it generates a magnetic field. The magnetic field attracts the valve core to move upward against the spring force, thereby opening the valve passage and allowing fluid to flow from the inlet to the outlet. The one-way solenoid valve ensures that the gas inside the connecting pipe 78 is stably delivered to the vaporized material conveying pipe 4, and the gas inside the vaporized material conveying pipe 4 will not flow back into the connecting pipe 78. When the solenoid coil is de-energized, the magnetic field disappears, the spring force pushes the valve core to reset, closes the valve passage, and prevents the fluid from flowing backward, thus achieving the one-way conduction function.

[0027] Please see Figures 1-3 The drive assembly 9 includes a gear ring 91 and a housing 92. The gear ring 91 is fixedly sleeved on the outside of the turntable 3 and located directly above the reactor body 2. The housing 92 is fixedly installed on one side of the top of the reactor body 2. A motor 93 is fixedly connected inside the housing 92. A drive shaft 94 is fixedly installed at the output end of the motor 93. One end of the drive shaft 94 passes through the housing 92 and extends to the outside of the housing 92. A drive wheel 95 is fixedly installed at one end of the drive shaft 94 and at the top of the gear ring 91. The drive wheel 95 is in the shape of a bevel gear. The teeth of the gear ring 91 are in the shape of bevel teeth. The drive wheel 95 meshes with the gear ring 91. The drive shaft 94 is rotatably connected to the housing 92 through a bearing. The motor 93 is connected to an external power supply and is equipped with the same power control switch.

[0028] Detailed implementation: Open the solenoid valve on the liquid inlet pipe 8 to transport the liquid material to be heated and mixed into the interior of the reactor body 2. High-temperature steam material is transported to each exhaust pipe 5 through the vaporization material conveying pipe 4. The first one-way valves 6 are opened by air pressure, allowing the high-temperature steam material to be transported from bottom to top inside the liquid material. Simultaneously, the steam material can assist in heating the liquid material. The collision between the airflow and the liquid achieves mixing between the materials. At the same time, the motor 93 inside the drive assembly 9 is started, driving the drive shaft 94 to rotate. The drive shaft 94 drives the drive wheel 95 to rotate, which in turn drives the gear ring 91 to rotate. The gear ring 91 drives the turntable 3 to rotate, which in turn drives the vaporization material conveying pipe 4 to rotate. The four exhaust pipes 5 are installed in a staggered pattern, so that when the vaporization material conveying pipe 4 rotates and drives the four exhaust pipes 5 to rotate, the liquid material inside the reactor body 2 can be stirred and mixed evenly, and the vapor material can be transported to various parts of the liquid material, achieving uniform mixing and concentration of the materials.

[0029] Because the density of the vaporized material at high temperature is much smaller than that of the liquid material, after entering the liquid, due to the large density difference, the vaporized material that has not fully participated in the mixing process tends to float quickly and remain above the liquid surface inside the reactor body 2. This allows the air pump 76 to be activated, drawing air from the annular pipe 73 through the air extraction pipe 75. The annular pipe 73 uses internal negative pressure to simultaneously open multiple second one-way valves 74 at the bottom, drawing out the residual vaporized material above the reactor body 2. This material is then transported through the air outlet pipe 77 to the tubular heat exchanger 72 for secondary heating. The heated vaporized material can then be transported by air pressure from the connecting pipe 78 to the vaporized material conveying pipe 4 for secondary recycling, reducing the waste of vaporized material and improving the accuracy of material mixing and preparation.

[0030] Furthermore, the gas transported in the secondary process can be discharged through the first one-way valve 6 on the four exhaust pipes 5, and transported from bottom to top inside the liquid material. This increases the gas transport distance inside the liquid, thereby extending the mixing time between the gas and the liquid, and thus improving the mixing effect between the materials.

[0031] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
