[0023] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention.

[0024] This application addresses the existing problem of some inorganic materials clogging pipelines during the feeding process. During manual unclogging, some inorganic materials can splash onto workers, increasing the risk of accidents. Furthermore, some inorganic materials can emit pungent acidic gases during the feeding process, causing eye and respiratory damage. Finally, some inorganic materials absorb moisture when exposed to air, causing a decrease in the quality of the reaction materials and thus affecting the reaction results.

[0025] The exhaust gas pipeline 3 and the protective gas pipeline connected to the raw material silo 1 in the present invention can quickly replace the air in the raw material silo 1, maintain the purity of the materials in the raw material silo 1, and effectively reduce the problem of inorganic materials being exposed to the air and absorbing moisture, thereby causing the quality of the reaction materials to deteriorate.

[0026] The present invention directly connects the raw material silo 1 to a suction pump 7 with a filter plate for providing negative pressure suction, thereby safely and efficiently transferring materials. At the same time, the exhaust gas is discharged through the exhaust pipe 3 to maintain a slight negative pressure in the reactor 11, which can effectively solve the blockage problem in the pipeline.

[0027] like Figure 1 As shown, in one embodiment, an inorganic closed feeding device includes:

[0028] The raw material silo 1 is connected to a raw material feed pipeline 2, an exhaust gas pipeline 3 and a protective gas pipeline 4. The raw material silo 1 is connected to the reactor 11 through a discharge pipeline 5.

[0029] During use, the inorganic materials can be sealed and transported to the site. This effectively reduces the time the inorganic materials are exposed to air during material transfer and feeding, preventing moisture absorption from affecting the quality of the reactants. Simultaneously, the inorganic material exhaust line 3 is closed, the shut-off valves 6 of the protective gas line and the inlet and outlet lines 5 are closed, and the material pump 10 is turned on to create a negative pressure within the silo. Once the negative pressure environment is established, the materials can be unsealed and fed. This prevents dangers caused by leakage or splashing during material transfer, and also prevents dangers caused by improper operation during feeding.

[0030] Optionally, the protective gas line is a nitrogen line, which fills the raw material silo 1 with nitrogen, and the nitrogen pressure in the protective gas line is 4.5 kPa. Optionally, the protective gas can also be other gases, such as helium and argon, as long as it can replace the air in the raw material silo 1, and this disclosure does not limit it.

[0031] After the material is sucked into the silo, the nitrogen and exhaust gas pipeline valves on the silo are opened for replacement, which effectively protects the gas in the silo, prevents moisture absorption, and discharges the air that enters the silo during the suction process;

[0032] Furthermore, after enough inorganic materials are transported to the raw material silo 1 by negative pressure, the feed pipeline and the extraction pump 7 are closed. The shut-off valve 6 at the bottom of the raw material and the feed valve 8 on the feed port of the reactor 11 are opened, and the inorganic materials are allowed to enter the reactor 11 by gravity. If the pipeline is blocked, the nitrogen shut-off valve 6 on the reactor 11 can be manually closed to stop the nitrogen seal. The tail gas system is used to discharge the tail gas, so that negative pressure is generated in the reactor 11 to suck the inorganic materials into the reactor 11. It should be noted that the reactor 11 is connected to the tail gas system and the nitrogen pipeline (not shown in the figure), which will not be described in detail here.

[0033] Optionally, a motor 9 is provided at the upper end of the reactor 11, and the transmission shaft of the motor 9 is connected to a stirring shaft 10 extending downward to the reaction cavity. When in use, the stirring shaft 10 is driven to rotate by the motor 9, thereby driving the stirring paddle in the reactor 11 to stir the inorganic material and improve the reaction effect.

[0034] Optionally, the bottom of the raw material silo 1 is a cone structure, and the discharge pipeline 5 is connected to the bottom of the cone structure, so that the material in the raw material silo 1 is more easily discharged under the action of gravity.

[0035] Optionally, the reactor is vertical or horizontal, which is not limited in the present disclosure.

[0036] The above description of the disclosed embodiments will enable one skilled in the art to implement or use the present invention. Various modifications to these embodiments will be readily apparent to one skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention is not limited to the embodiments shown herein but is intended to conform to the widest scope consistent with the principles and novel features disclosed herein.
