For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0031] In addition, the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0032] Reference Figure 1 , Figure 2 and Figure 3As shown, the present invention provides a closed rotary reactor structure, comprising: a frame 1, a reactor body 2 and a crystal adding device 3; the frame 1 is provided with a rotating shaft 11; the reactor body 2 is arranged on the frame 1 and is suitable for rotating around the rotating shaft 11, the reactor body 2 is provided with a feed port 21, and the feed port 21 is covered with an end cover; the crystal adding device 3 is fixedly connected to the inner side of the end cover, the crystal adding device 3 is provided with a accommodating cavity suitable for containing crystals, one side of the crystal adding device 3 is provided with a feeding port 34 connected with the accommodating cavity, and an adjusting plate 33 is rotatably provided at the feeding port 34; the feeding port 21 is rotated to above the rotating shaft 11 so that the adjusting plate 33 has an open state; the feeding port 21 is rotated to below the rotating shaft 11 so that the adjusting plate 33 has a closed state; in the open state, the crystal enters the reactor body 2 from the accommodating cavity through the feeding port 34; in the closed state, the adjusting plate 33 blocks the feeding port 34 to prevent the crystal in the reactor body 2 from flowing back to the crystal adding device 3.

[0033] Specifically, a crystal adding device 3 is arranged at the feed port 21 of the kettle body 2, and the crystal adding device 3 is fixedly connected to the inner side of the end cover. During the rotation of the kettle body 2 around the rotating axis 11, the crystal adding device 3 is driven to rotate. The crystal adding device 3 is provided with a containing cavity suitable for containing crystals. A feeding port 34 is arranged on one side of the crystal adding device 3, and an adjusting plate 33 is rotatably arranged at the feeding port 34. During the rotation of the kettle body 2, under the action of gravity and centrifugal force, the adjusting plate 33 has an open state and a closed state. When the feed port 21 rotates to above the rotating axis 11, the adjusting plate 33 is in an open state. In the open state, the crystal enters the kettle body 2 through the feeding port 34, thereby realizing the addition of crystals during the reaction process. When the kettle body 2 rotates to below the rotating axis 11, due to the action of gravity, the crystals in the kettle body 2 are accumulated below, thereby pressurizing the adjusting plate 33, so that the adjusting plate 33 is in a closed state, thereby preventing the crystals in the kettle body 2 from flowing back to the crystal adding device 3 and affecting the reaction efficiency. The closed rotary reactor structure enables crystal addition during the closed reaction process without interrupting the reaction, thereby improving production efficiency.

[0034] It can be understood that an interlayer is provided in the kettle body 2, and a coil is provided in the interlayer. The conduction tube group is connected to the coil via the rotating shaft 11. During the reaction, a heat-conducting medium is introduced into the conduction tube group, so that the kettle body 2 is heated evenly and the reaction efficiency is improved. When the kettle body 2 needs to be cooled at the end of the reaction or during the reaction, cooling water is introduced into the conduction tube group to quickly cool the kettle body 2 and improve efficiency.

[0035] A vacuum pressure gauge is provided at the other end of the rotating shaft 11, and the vacuum pressure gauge is connected to the kettle body 2 through an air pipeline, so as to monitor the reaction gas pressure in the kettle body 2 in real time. A vacuum filter is provided at one end of the air pipeline extending in the kettle body 2 to prevent crystals from flowing out of the air pipeline and affecting the reaction effect. A seal is provided between the air pipeline and the kettle body 2.

[0036] In some embodiments of the present invention, the crystal adding device 3 includes a shell 31 and a regulating switch 32; one side of the shell 31 is fixedly connected to the inner side of the end cover, a accommodating cavity is provided in the shell 31, and a adding port 34 is provided at one end of the shell 31; the regulating switch 32 is provided in the accommodating cavity, and the regulating switch 32 is suitable for monitoring the crystal temperature in the accommodating cavity to control the regulating plate 33 to be in a locked state or an active state; in the locked state, one side of the regulating plate 33 is hinged to the shell 31, and the other side of the regulating plate 33 is clamped and fixed to the shell 31; in the active state, one side of the regulating plate 33 is hinged to the shell 31, and the other side of the regulating plate 33 is detached from the shell 31, so that when the kettle body 2 rotates, the regulating plate 33 can realize the open state and the closed state.

[0037] Specifically, the setting of the control switch 32 allows the crystals in the crystal adding device 3 to enter the kettle body 2 under the set temperature conditions to ensure the reaction quality. When the crystals in the accommodating chamber do not reach the set temperature, the control switch 32 controls the adjustment plate 33 to be in a locked state. In the locked state, when the crystal adding device 3 moves with the kettle body 2, the adjustment plate 33 is always in a closed state, that is, the crystals in the accommodating chamber cannot flow out, and the crystals in the kettle body 2 cannot enter the accommodating chamber. When the temperature of the crystals in the accommodating chamber rises to the set temperature, the control switch 32 controls the adjustment plate 33 to be in an active state. At this time, when the feed port 21 of the kettle body 2 rotates to the top of the rotating shaft 11, the adjustment plate 33 is in an open state, and the crystals in the accommodating chamber enter the kettle body 2 under the action of gravity and centrifugal force to react, so as to achieve the addition of crystals in the sealed reaction process. When the feed port 21 rotates to the bottom of the rotating shaft 11, the adjustment plate 33 is in a closed state under the extrusion of the external crystals, and the adjustment plate 33 realizes the isolation of the accommodating chamber from the crystals in the kettle body 2, thereby ensuring a good reaction effect.

[0038] It is understandable that the regulating switch 32 realizes temperature control of the added crystal, thereby avoiding the problem of poor quality of the finished product due to the crystal being too low in temperature.

[0039] In some embodiments of the present invention, the control switch 32 includes:

[0040] A clamping arm 321, one end of which is clamped with the other side of the adjustment plate 33 through a rotating structure;

[0041] A sleeve 322 is disposed in the accommodating cavity, and a buckle 323 is disposed at one end of the sleeve 322;

[0042] An elastic member, disposed in the sleeve 322;

[0043] The other end of the clamping arm 321 extends into the sleeve 322 and is clamped with the locking piece 323. The clamping arm 321 is located at the first rotation position, and the adjustment plate 33 is in a locked state. The elastic member can push the other end of the clamping arm 321 out to separate from the locking piece 323. The clamping arm 321 is located at the second rotation position, and the adjustment plate 33 is in an active state.

[0044] Specifically, the clamp arm 321 switches between the first rotation position and the second rotation position to realize the switch between the locked state and the active state of the adjustment plate 33. When the reaction starts, the crystal is first added to the accommodating chamber, the sleeve 322 is fixed in the accommodating chamber and partially buried in the crystal, the adjustment plate 33 is snapped with the feeding port 34, and the clamp arm 321 is rotated to the first rotation position, at which time the clamp arm 321 fixes the adjustment plate 33, and the other end of the clamp arm 321 extends to the inside of the sleeve 322, and is clamped and fixed with the clamp 323 on the sleeve 322, and the clamp arm 321 abuts against the elastic member in the sleeve 322; then the crystal adding device 3 is fixedly installed on the end cover, the end cover is covered, and the reaction is started after setting the parameters.

[0045] After the temperature of the crystal rises to the preset temperature, the elastic part is lifted up to push the clamping arm 321 out of the clamping member 323. At this time, the clamping arm 321 is in the second rotation position, one side of the adjustment plate 33 is detached, and the other side is hinged to the shell 31. During the rotation process, the open state and the closed state are realized.

[0046] It is understood that the set temperature of the crystal addition can be adjusted by controlling the material, type and length of the elastic member.

[0047] Specifically, in some embodiments of the present invention, the elastic member is a thermal expansion material, and the sleeve 322 is a thermally stable metal material.

[0048] In some embodiments of the present invention, the opening direction of the material adding port 34 is perpendicular to the rotating shaft 11 and faces the inner wall of the kettle body 2 .

[0049] Specifically, to ensure that the adjustment plate 33 can be switched between the open state and the closed state under the action of gravity and centrifugal force, the opening direction of the feeding port 34 needs to be perpendicular to the rotating shaft 11 and toward the inner wall of the kettle body 2, so as to ensure normal addition of crystals.

[0050] In some embodiments of the present invention, a feeding port is provided on one side of the shell 31 , and a cover plate is provided at the feeding port, and the cover plate is fixedly connected to the shell 31 .

[0051] Specifically, a feeding port is provided on one side of the housing 31, and the crystal is added into the accommodating cavity from the feeding port. After the crystal is added into the accommodating cavity, the cover plate is fixedly connected to the housing 31 to seal the feeding port, so that the crystal can only be put into the kettle body 2 from the feeding port 34. The cover plate and the housing 31 can be fixedly connected by screws, or by snap-fit ​​connection.

[0052] In some embodiments of the present invention, a partition is disposed on one side of the accommodating cavity close to the adjusting plate 33 , and a plurality of through holes are opened on the partition to form a material adding port 34 , and the adjusting plate 33 can cover the through holes.

[0053] In some embodiments of the present invention, the partition includes a sealing section and a porous section, and the projection area of ​​the adjustment plate 33 on the partition is greater than or equal to the area of ​​the porous section.

[0054] Specifically, a plurality of through holes are provided on the partition to form a feeding port 34, and the regulating plate 33 is covered on the through holes. The partition includes a sealing section and a porous section, and the projection area of ​​the regulating plate 33 on the partition is greater than or equal to the area of ​​the porous section, thereby ensuring that in the closed state, the crystals in the kettle body 2 are prevented from flowing back into the accommodating chamber.

[0055] It is understandable that the speed of adding crystals can be further controlled by the size and arrangement density of the through holes to ensure the normal progress of the reaction.

[0056] In some embodiments of the present invention, the kettle body 2 is further provided with a discharge port 22 , the feed port 21 and the discharge port 22 are located on the same axis, and the connecting line between the feed port 21 and the discharge port 22 is perpendicular to the rotating shaft 11 .

[0057] Specifically, a feed port 21 and a discharge port 22 are provided on the kettle body 2, and the feed port 21 and the discharge port 22 are located on the central axis, thereby avoiding the formation of a dead zone and preventing crystals from piling up in the dead zone to affect production efficiency.

[0058] In some embodiments of the present invention, a mesh screen is provided in the kettle body 2, and the crystal adding device 3 is located between the end cover and the mesh screen. The crystals in the accommodating cavity fall into the kettle body 2 after being dispersed by the mesh screen.

[0059] Specifically, when the feed port 21 is located above the rotating shaft 11, the crystals flow out from the feed port 34, are dispersed by the mesh screen and fall into the kettle body 2. The setting of the mesh screen ensures the uniformity of crystal dispersion and further avoids the backflow of crystals.

[0060] Although the embodiments of the present invention have been described in conjunction with the accompanying drawings, those skilled in the art may make various modifications and variations without departing from the spirit and scope of the present invention, and such modifications and variations are all within the scope defined by the appended claims.
