[0025] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0026] Embodiment 1:

[0027] Reference Figure 1-4 A solid feeding device for an intermittent reactor comprises a reactor body 1, and also comprises: a frame 4, fixedly connected to the reactor body 1, the bottom of the frame 4 being in communication with the reactor body 1; a partition 501, arranged at the top of the frame 4; a partition 601, slidably connected in the frame 4, the partition 601 being located at the bottom of the frame 4; a feed pipe 401, connected to the frame 4, the feed pipe 401 being used to transport materials between the partition 501 and the partition 601, and the feed pipe 401 having a plurality of holes. A one-way valve is provided; an air pump 7 is fixedly connected to the reactor body 1, an air inlet pipe 701 is connected to the air inlet end of the air pump 7, the air inlet pipe 701 is used to extract the gas between the partition 1 501 and the partition 2 601, a feed port 101 and a discharge port 102 are provided on the reactor body 1, a stirring shaft 3 is rotatably connected in the reactor body 1, the stirring shaft 3 is used to stir the material, a driving motor 2 is fixedly connected to the reactor body 1, and the stirring shaft 3 is fixedly connected to the output end of the driving motor 2.

[0028] The partition 1 501 and the partition 2 601 are consistent in size with the interior of the frame 4. The corners can be sealed with rubber strips to prevent gas leakage. The reactor body 1 is an indirect reactor.

[0029] When the device is in use, the material is poured in through the feed port 101, and the air pressure is adjusted to a suitable position, the feed port 101 is closed, the reactor body 1 and the drive motor 2 are started, and the material is processed to react at a suitable temperature and pressure. When the material needs to be supplemented, the feed pipe can be connected to the feed pipe 401 to allow a suitable amount of material to enter the space between the partition 1 501 and the partition 2 601, and then the gas in the space is sucked out by the air pump 7 to make it close to a negative pressure state, and then the partition 2 601 is moved to allow the material to enter the reactor, thereby completing the feeding. After completion, the partition 2 601 is reset, and the reactor is sealed again to facilitate the reaction.

[0030] Embodiment 2:

[0031] Reference Figure 1-4, a solid feeding device for an intermittent reactor, which is basically the same as Example 1, and further: a telescopic rod 2 6 is fixedly connected to the frame 4, and the telescopic end of the telescopic rod 2 6 is fixedly connected to the partition 2 601, a telescopic rod 1 5 is fixedly connected to the reactor body 1, and a connecting rod is fixedly connected to the telescopic end of the telescopic rod 1 5, and the connecting rod is fixedly connected to the partition 1 501.

[0032] When the device is replenishing materials, the telescopic rod 15 can be started to displace the partition 1501 through the telescopic rod 15, and then move downward to make part of the materials attached to the inner wall of the frame 4 fall down. At the same time, the displacement will squeeze the gas in the frame 4 and make it re-enter the reactor body 1, so as to maintain a relatively stable pressure inside the reactor and facilitate the reaction process. When the partition 1501 pushes the materials on the frame 4, it can be reset. When it comes to the top of the partition 2 601, the telescopic rod 26 can be used to reset the partition 2 601 to avoid the backflow of gas. Then the partition 1 501 is reset under the action of the telescopic rod 15 to facilitate the next use.

[0033] The utility model can reduce the entry of external gas or the discharge of internal gas through the arrangement of the partition 1 501, the partition 2 601 and the air pump 7 during use, effectively maintain the air pressure inside the reactor, and facilitate the reaction between materials.

[0034] The above is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent substitutions or changes within the technical scope disclosed by the present invention according to the technical solution and inventive concept of the present invention, which should be covered by the protection scope of the present invention.
