Specific embodiments

[0020] The following further describes the present application in detail with reference to the accompanying drawings.

[0021] Embodiment 1

[0022] As Figure 1 - Figure 6As shown in the figure, a heat recovery device for a saccharification system includes a bottom plate 1, a saccharification mechanism and a preheating box 6 installed on the top of the bottom plate 1. The saccharification mechanism includes a heating box 2 installed on the top of the bottom plate 1, a saccharification box 3 installed on the top of the heating box 2, and a stirring mechanism installed in the saccharification box 3. An installation cylinder 4 is installed on the top of the saccharification box 3. A feed hopper is installed on the top of the saccharification box 3. A drain pipe is installed on one side of the bottom of the saccharification box 3, and a control valve is installed outside the drain pipe. The stirring mechanism includes a rotating rod 10 rotatably connected in the saccharification box 3, a driving wheel 19 installed outside the rotating rod 10 and located in the installation cylinder 4, and a plurality of stirring rods 11 installed on the rotating rod 10. A heating seat 12 is installed inside the heating box 2. An annular cylinder 13 is installed on the inner wall of the heating box 2, which is arranged around the heating seat 12 and has a plurality of ventilation openings on the inner side. A plurality of heat dissipation openings 20 are opened at the bottom of the heating box 2. Air supply mechanisms for supplying air into the annular cylinder 13 are installed on both sides of the installation cylinder 4. Among them, the air supply mechanism includes an installation box 5 installed on one side of the installation cylinder 4, a rotating rod 17 rotatably connected to the inner wall of one side of the installation box 5, and a plurality of rotating blades 18 installed outside the rotating rod 17. A first bevel gear 15 is installed outside the rotating rod 10. One end of the rotating rod 17 extends into the installation cylinder 4 and is installed with a second bevel gear 16 meshing with the first bevel gear 15. One side of the installation box 5 is communicated with the annular cylinder 13 through an air inlet pipe 9. An air inlet 23 is opened on one side of the installation box 5. The rotating blades 18 are located between the air inlet 23 and the air inlet pipe 9, and the air inlet 23 is located on the side close to the installation cylinder 4. A limiting groove 24 communicated with the air inlet 23 is opened on the top of the installation box 5. A filter screen 22 is inserted into the air inlet 23. A limiting plate 21 matched with the limiting groove 24 is installed on the top of the filter screen 22. By providing the filter screen 22, the gas entering the installation box 5 can be filtered, so as to reduce the impurities contained in the gas. When the filter screen 22 needs to be cleaned, the limiting plate 21 can be directly pulled upward, and the filter screen 22 can be directly removed, so as to facilitate the cleaning of the filter screen 22.

[0023] It should be noted that for the heat recovery device of the saccharification system, when the heating base 12 heats the liquid inside the saccharification tank 3 during use, a large amount of steam will be generated. The steam pressure generated will push the driving wheel 19 to rotate, converting thermal energy into mechanical energy. When the driving wheel 19 rotates, it will drive the rotating rod 10 to rotate. Driven by the rotating rod 10, multiple rotating rods 17 will rotate, thereby stirring the liquid inside the saccharification tank 3. When the rotating rod 10 rotates, it will drive the first ZhuiChi wheel 15 to rotate. Under the meshing of the first bevel gear 15 and the second bevel gear 16, the rotating rod 17 will rotate, and the rotating rod 17 will drive multiple rotating blades 18 to rotate, thereby generating wind power. The generated wind power will enter the annular cylinder 13 through the air inlet pipe 9 and finally be blown onto the heating base 12 through multiple ventilation openings, thereby dissipating heat from the heating base 12 and extending the service life of the heating base 12.

[0024] Embodiment 2

[0025] Combined with Figure 1 、 Figure 2 and Figure 4 As shown, on the basis of Embodiment 1, the further improvement of this embodiment lies in: a heat conduction pipe 14 with a spiral structure is installed inside the preheating tank 6. A feed pipe is installed at the top of the preheating tank 6. The top of the installation cylinder 4 is connected to the top end of the heat conduction pipe 14 through an air inlet pipe 8, and the bottom end of the heat conduction pipe 14 extends to the outside of the preheating tank 6. A receiving box located at the bottom end of the heat conduction pipe 14 is placed on the top of the bottom plate 1. A pumping pump 7 is installed outside the preheating tank 6. The inlet of the pumping pump 7 is connected to the preheating tank 6 through a feed pipe, and the outlet of the pumping pump 7 is connected to the top of the saccharification tank 3 through a discharge pipe, and a valve is installed outside the discharge pipe.

[0026] The difference between this embodiment and Embodiment 1 is that the hot steam discharged through the air inlet pipe 8 will enter the inside of the heat conduction pipe 14. At this time, under the action of heat and cold exchange, the liquid to be saccharified inside the preheating tank 6 will be preheated, thereby enabling the steam heat in the entire saccharification system to be recycled again. In this way, the liquid to be saccharified can be heated first, thereby improving the saccharification effect of the subsequent saccharification system and making it more convenient for people to use.

[0027] The above-described embodiments only represent several implementation manners of the present invention. The description is relatively specific and detailed, but it should not be construed as a limitation on the scope of the patent of the present invention. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present invention, several deformations and improvements can still be made, and these all belong to the protection scope of the present invention.
