DETAILED DESCRIPTION

It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0025] The specific implementation of the present invention is described in detail below in conjunction with specific embodiments.

[0026] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 FIG. 1 is a schematic diagram of the overall structure of a steam direct heating tank provided by an embodiment of the present invention, wherein the steam direct heating tank comprises:

[0027] A box body 1, wherein the box body 1 is provided with a rotating bracket 4, on which a heating tank 2 is rotatably provided, a plurality of installation cavities 17 are provided in the heating tank 2, a shunt pipe 10 is provided in the installation cavity 17, an air inlet disk 15 is provided at the bottom of the inner cavity of the heating tank 2, a plurality of air inlet holes 16 are provided on the air inlet disk 15, the air inlet disk 15 is communicated with the shunt pipe 10, a shunt cavity 8 is provided at the top of the inner cavity of the heating tank 2, the shunt cavity 8 is communicated with the shunt pipe 10, an air guide pipe 9 is fixedly connected to the shunt cavity 8, the air guide pipe 9 is rotatably connected to the box body 1, two groups of shunt cavities 8 are provided, both of which are communicated with the inside of the heating tank 2, and the two groups of shunt cavities 8 are respectively connected with a first guide pipe 11 and a second guide pipe 13, both of which are fixed to the heating tank 2 by a fixing clamp 14, a connecting pipe 24 is provided at the bottom of the shunt cavity 8, and a second electric control valve 25 is provided in the connecting pipe 24;

[0028] A material control mechanism, which is arranged at the bottom of the heating tank 2 and is used to control the material to enter and exit the heating tank;

[0029] A circulating condensing mechanism is installed in the box 1 and is used to condense and cool the steam.

[0030] In the embodiment of the present invention, when heating is performed, a steam generating device is used to generate high-temperature and high-pressure steam, hereinafter referred to as steam. A third electrically controlled valve and a fourth electrically controlled valve are respectively provided on the first flow guide pipe 11 and the second flow guide pipe 13, and a fifth electrically controlled valve is provided in the air inlet disk 15. The material to be heated is first introduced into the heating tank 2, and a feed pipe is connected to the flow pipe 18, and the feed pipe is extended into the raw material tank. The raw material tank stores the material to be heated. At this time, the third electrically controlled valve, the fourth electrically controlled valve and the fifth electrically controlled valve are closed, and the first electrically controlled valve 23 and the second electrically controlled valve 25 are opened, and the material control mechanism is opened. At this time, the air guide pipe 9 is connected to the negative pressure device. At this time, due to the negative pressure state in the heating tank, the material will gradually enter the heating tank through the flow pipe 18. In the tank 2, after the material introduction is completed, the feed pipe is separated from the raw material tank, so that the residual material in the flow pipe 18 enters the heating tank 2. At this time, the first electric control valve 23 is closed, and the material control mechanism is closed. At this time, the air guide pipe 9 is connected to the positive pressure device, and steam is introduced from the air guide pipe 9. At this time, the second electric control valve 25 is closed, and the third electric control valve, the fourth electric control valve and the fifth electric control valve are opened synchronously. The steam first reaches the diverter chamber 8, and the diverter chamber 8 is connected to a plurality of diverter pipes 10. The diverter pipe 10 passes through the inner wall of the heating tank 2 to achieve heating of the heating tank 2 body. The steam reaches the air inlet disk 15 through the diverter pipe 10. The air inlet disk 15 is provided with a plurality of air inlet holes 16. Then the steam will be transformed into a plurality of bubbles and enter the heating tank 2, and from the heating tank 2 gradually rises from the bottom to the top and reaches the reflux chamber 7. At this time, the steam undergoes two heat exchanges and its temperature is reduced. At this time, the third electric-controlled valve and the fourth electric-controlled valve are in the open state, so the steam will be discharged from the first air port 12 and the second air port synchronously. Since the exhaust directions of the first air port 12 and the second air port are completely opposite, the heating tank 2 is in a stable state, and the steam in the heating tank 2 will rise vertically from the bottom. In order to improve the heat exchange efficiency and increase the moving path length of the steam bubbles in the material, the third electric-controlled valve and the fourth electric-controlled valve are opened alternately at this time. When the third electric-controlled valve is opened, the fourth electric-controlled valve is closed, and when the third electric-controlled valve is closed, the fourth electric-controlled valve is opened. Under the reaction force of the steam, the heating tank 2 will be discharged relative to the rotating bracket 4. Now it swings, because the steam will move upward under the action of buoyancy, when the heating tank 2 is in a swinging state, the path of the steam bubbles in the material in the heating tank 2 is close to a Z-shape, which greatly increases the moving path length of the steam bubbles, and the heat exchange between the steam bubbles and the material will be more sufficient, and the heat exchange efficiency will also be greatly increased. When the heating is completed, the third electrically controlled valve, the fourth electrically controlled valve and the fifth electrically controlled valve are closed synchronously, the second electrically controlled valve 25 is opened, the material control mechanism is opened, and the first electrically controlled valve 23 is opened. The steam generating device no longer heats, but directly inputs gas into the air guide pipe 9. By introducing gas into the heating tank 2, the gas pressure in the heating tank 2 is increased, so that the material in the heating tank 2 is discharged from the flow pipe 18, thereby realizing the discharge of the material.

[0031] like Figure 1 , Figure 2 and Figure 7 As shown, as a preferred embodiment of the present invention, the material control mechanism includes a fluid delivery pipe 18, a leakage hole is provided at the bottom of the heating tank 2, a first electric-controlled valve 23 is installed in the leakage hole, a first electromagnet 22 is installed on the first electric-controlled valve 23, the fluid delivery pipe 18 is fixedly installed at the bottom of the box body 1, a first joint 20 is provided at the end of the fluid delivery pipe 18, the first electric-controlled valve 23 is fixedly connected to the second joint 21, and a magnetic ring 26 is fixedly connected to the first joint 20.

[0032] In this embodiment, when the material control mechanism is turned on, the first electromagnet 22 is energized, and the magnetic field generated by the first electromagnet 22 will attract the magnetic ring 26, and the magnetic ring 26 drives the first joint 20 to move upward, and the first joint 20 and the second joint 21 are abutted against each other, and the two are connected. At this time, the material can be transported into the heating tank 2, or discharged from the heating tank 2.

[0033] like Figure 1 , Figure 2 and Figure 7 As shown, as a preferred embodiment of the present invention, the circulating condensation mechanism includes a condenser 3, a circulating pump 6 is arranged at the bottom of the box body 1, and two groups of condensers 3 are arranged. The two groups of condensers 3 are respectively located on the inner wall of the box body 1, and the two groups of condensers 3 are respectively connected to the liquid inlet and liquid outlet of the circulating pump 6 through two groups of liquid guide tubes 5. The two groups of condensers 3 are connected to each other, and the circulating pump 6 is used to drive the liquid to circulate in the condenser 3.

[0034] In this step, since steam is a high-temperature and high-pressure gas and cannot be discharged directly, a condenser 3 is set in the box body 1, and the circulating pump 6 drives the liquid to circulate in the condenser 3. The steam discharged from the first guide tube 11 and the second guide tube 13 will directly contact the condenser 3 to achieve the effect of cooling and condensation. The condensed liquid can be recycled or directly discharged.

[0035] like Figure 1 , Figure 2 and Figure 7 As shown, as a preferred embodiment of the present invention, a box door is arranged on the side of the box body 1, a sealing strip is arranged between the box door and the box body 1, and an air pressure balance hole is arranged on the top of the box body 1.

[0036] In this embodiment, by providing a sealing strip, it is possible to ensure that the box body 1 is in a sealed state as a whole, the liquid inside will not leak, and the pressure change in the box body 1 can also be balanced through the air pressure balance hole.

[0037] As a preferred embodiment of the present invention, an observation window is provided on the side of the box body 1.

[0038] In this embodiment, the internal operation can be directly observed by setting an observation window.

[0039] As a preferred embodiment of the present invention, a temperature sensor, a liquid level sensor and an air pressure sensor are arranged inside the heating tank 2, and an inclination sensor is fixedly installed outside the heating tank 2.

[0040] In this embodiment, a temperature sensor is provided to monitor the temperature of the material in real time. When the temperature reaches the standard, the heating can be stopped. The liquid level sensor can detect the internal liquid level to obtain the input amount of the material. The air pressure sensor is used to detect the internal air pressure. The inclination sensor is used to detect the inclination of the heating tank 2. The inclination data collected by the inclination sensor is used to control the opening windows of the first guide tube 11 and the second guide tube 13, so that the heating tank 2 always swings within a certain range.

[0041] As a preferred embodiment of the present invention, the first air port 12 and the second air port are respectively provided on the first air guide tube 11 and the second air guide tube 13 , and the exhaust directions of the first air port 12 and the second air port are perpendicular to the central axis of the heating tank 2 .

Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
