[0020] The utility model is further described below in conjunction with the accompanying drawings and specific embodiments.

[0021] Example 1

[0022] like Figure 1 , Figure 2 As shown, in this example, a phosphorus-doped beet pulp biochar carbonization device includes a tank body 1, which is vertically arranged. A cooling zone 2, a combustion zone 3, and a heat preservation zone 5 are sequentially arranged in the cavity of the tank body 1 along the axial direction from top to bottom, wherein the cooling zone 2 is water-cooled, such as a cooling pipe is installed in the cavity wall or the peripheral wall of the tank body 1 in the cooling zone 2. A plurality of microwave transmitting tubes 16 are spaced apart at the peripheral wall of the tank body 1 corresponding to the combustion zone 3, such as multiple microwave transmitting tubes 16 are installed at intervals along the axial direction of the tank body 1, and the microwave transmitting tubes 16 are connected to an external microwave generator. The cavity of the tank body 1 below the combustion zone 3 is a heat preservation zone 5, and a discharge port is formed at the cavity bottom wall of the heat preservation zone 5, and a star-shaped discharger 10 is installed at the discharge port. The outlet of the discharge port is connected to the inlet of the spiral feeding mechanism 11, and a star-shaped discharger 2 12 is installed at the outlet of the spiral feeding mechanism 11.

[0023] An exhaust port is formed at the top of the tank body 1, and the exhaust port is connected to an external cooler 8. A drive motor 6 is fixed at the top of the tank body 1, and the drive motor 6 is connected to a rotating shaft in the cavity of the tank body 1. A stirring paddle 4 is installed on the rotating shaft to stir materials such as beet pulp.

[0024] like Figure 1 As shown, the shell 9 covers the microwave emitting tube 16, and the shell 9 is slidably connected with the bracket 14 along the radial direction of the tank body. For example, the top end of the bracket 14 is slidably connected with the top cavity wall of the shell 9, and the microwave emitting tube 16 is installed at the wall of the tank body 1 corresponding to the sliding direction of the bracket 14. The cylinder body 13 is fixed at the position of the bracket 14 corresponding to the microwave emitting tube 16. For example, fixing plates 17 are formed on the bracket 14 at corresponding positions along the length direction, and the fixing plates 17 are fixed to the peripheral wall of the cylinder body 13 by bolts or the like.

[0025] A water-cooling pipe 19 is placed in the cavity of the cylinder 13, such as a spiral extension type. In this example, a notch is formed axially at the top wall and the bottom wall of the cylinder 13, and the notch is the slide groove 18. During installation, the air inlet end and the air outlet end of the water-cooling pipe 19 correspond to the notches of the slide groove at the top wall and the bottom wall of the cylinder 13 respectively, and the water-cooling pipe can be inserted.

[0026] In order to effectively prevent the water-cooling pipe from detaching, a baffle is slidably connected to the peripheral wall of the cylinder 13 on one side of the end of the slide groove 18, and the baffle moves along the circumference of the cylinder 13. When the water inlet end of the water-cooling pipe moves forward to the end of the slide groove, the baffle is moved so that its end is above the slide groove behind the water inlet end. The water inlet end moves backward and abuts the baffle to form a limit. When the water-cooling pipe is damaged, the baffle can be slid to release the limit, and then the water-cooling pipe can be directly slid out of the cylinder, which is convenient for installation and disassembly.

[0027] For the convenience of maintenance, an inspection opening can be formed at the shell corresponding to the sliding direction of the bracket 14, and a door panel 15 is hinged at the inspection opening. The door panel can be opened to observe or repair the shell cavity.

[0028] When in use, the water cooling pipe is connected to the external water supply pipe, and the sliding bracket can make the corresponding microwave transmitting tube in or out of the cylinder cavity. Beet residue is used as raw material and phosphoric acid is used as activator. After mixing, it is fed into the feed port and discharged from the discharge port through the spiral feeding mechanism after microwave carbonization.

[0029] The above are only preferred implementations of the utility model. The protection scope of the utility model is not limited to the above embodiments. All technical solutions under the idea of ​​the utility model belong to the protection scope of the utility model. It should be pointed out that for ordinary technicians in this technical field, some improvements and modifications without departing from the principle of the utility model should also be regarded as the protection scope of the utility model.
