[0016] The technical solutions in the embodiments of the present application will be described clearly and completely below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only some of the embodiments of the present application, not all. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor are within the scope of protection of the present application.

[0017] Figure 1 A structural schematic diagram of a laboratory full-automatic main reaction device provided by the embodiment of the present application. The embodiment of the present application provides a laboratory full-automatic main reaction device, which comprises:

[0018] The sealing outer frame is provided with an outer conveying opening on one side surface, and the outer conveying opening is slidingly provided with an outer sealing door 4;

[0019] The conveying unit is arranged on the side surface of the sealing outer frame close to the outer conveying opening, and is used for conveying the reaction kettle from the outside of the sealing outer frame to the inside of the sealing outer frame;

[0020] A rotating manipulator 5 is arranged on the inner top surface of the sealed outer frame, and the end of the rotating manipulator 5 is provided with a clamping manipulator 6. The clamping manipulator 6 is rotated to above the part of the conveying unit located inside the sealed outer frame under the driving of the rotating manipulator 5, clamps the reaction kettle on the conveying unit, and then rotates the reaction kettle to the main reaction station inside the sealed outer frame by the rotating manipulator 5.

[0021] A feeding unit is arranged on the inner top surface of the sealed outer frame, and the feeding unit is located above the main reaction station. When the reaction kettle is placed on the main reaction station, the feeding unit is sealingly connected with the reaction kettle to feed the reaction kettle.

[0022] Exemplarily, the sealed outer frame forms a sealed structure after the outer sealing door 4 is closed. Even if toxic substance leakage or combustion explosion accidents occur during the feeding or main reaction of the reaction kettle, the influence of the accidents will be limited in the sealed outer frame and will not overflow to the external environment, thereby effectively ensuring the safety of the experimenters. In order to achieve this effect, the sealed outer frame and the outer sealing door 4 need to be made of materials with certain explosion-proof ability, such as steel plates or explosion-proof glass.

[0023] In use, the main reaction device of the present application places a reaction kettle with appropriate size at point A on the conveying unit, and then conveys the reaction kettle to point B inside the sealed outer frame under the working of the conveying unit. Then, the rotating manipulator 5 drives the clamping manipulator 6 to rotate 180 degrees, so that the clamping manipulator 6 rotates to the position corresponding to the reaction kettle. Then, the clamping manipulator 6 tightens to clamp the reaction kettle. The rotating manipulator 6 reversely rotates 180 degrees, so that the clamping manipulator 6 moves to the main reaction station, i.e., point C, with the reaction kettle. At this time, the clamping manipulator 6 releases the reaction kettle. Finally, the feeding unit is lowered or the main reaction station is raised, so that the feeding unit is sealingly connected with the feeding port of the reaction kettle. With the feeding of the feeding unit into the reaction kettle, the main reaction can be started.

[0024] In a possible embodiment, the conveying unit includes an outer window conveying unit 2 and an inner window conveying unit 1. The outer window conveying unit 2 and the inner window conveying unit 1 are arranged on the outer side surface and the inner side surface of the same position of the side wall of the sealed outer frame, respectively. The top of the outer window conveying unit 2 and the inner window conveying unit 1 is higher than the bottom edge of the outer conveying opening.

[0025] Exemplarily, the outer window conveying unit 2 and the inner window conveying unit 1 are respectively located on the outer side and the inner side of the side wall of the sealed outer frame, and the outer sealing door 4 is arranged inside the side wall of the sealed outer frame, so that the outer sealing door 4 is not hindered when being lifted or lowered. Moreover, there is a gap 7 between the outer window conveying unit 2 and the inner window conveying unit 1, so the outer sealing door 4 will pass through the gap 7. When the outer sealing door 4 is completely opened, there will be no obstruction between the outer window conveying unit 2 and the inner window conveying unit 1, and the reactor can be directly conveyed from the outer window conveying unit 2 to the inner window conveying unit 1. Moreover, the width of the gap 7, i.e. the thickness of the side wall of the sealed outer frame, is less than half of the size of the bottom of the reactor, so when the reactor is conveyed to the end of the outer window conveying unit 2, it can continue to move to the inner window conveying unit 1 and will not be unable to continue to move due to falling into the gap 7.

[0026] In a possible embodiment, the inside of the sealed outer frame is vertically provided with a partition plate in the direction close to the side surface with the conveying unit, the partition plate is provided with an inner conveying opening, the inner conveying opening is slidingly provided with the inner sealing door 3, and the inner conveying opening and the outer conveying opening are oppositely arranged.

[0027] Exemplarily, the partition plate and the side surface of the sealed outer frame with the conveying unit form a nitrogen replacement area, and the nitrogen replacement area is provided with a nitrogen replacement device for replacing the gas in the nitrogen replacement area with nitrogen. When the reactor is conveyed by the conveying unit to the inside of the sealed outer frame, the outer sealing door 4 will be closed, at this time, the space where the reactor is located is a sealed space, and at this time, the inner sealing door 3 is also in a closed state, so the reactor is isolated from the space outside the sealed outer frame and the space inside the sealed frame except the nitrogen replacement area, at this time, the nitrogen replacement area can be replaced with nitrogen to ensure that the nitrogen replacement area and other spaces inside the sealed frame are also filled with nitrogen, so that even if a combustion and explosion accident occurs during the main reaction process of the reactor, the influence of the combustion and explosion accident will not be magnified.

[0028] In a possible embodiment, the nitrogen replacement device comprises a vacuumizing unit and a nitrogen injection unit, the vacuumizing unit is used to vacuumize the nitrogen replacement area when the inner sealing door 3 and the outer sealing door 4 are both closed, and the nitrogen injection unit is used to inject nitrogen into the nitrogen replacement area in a vacuum state.

[0029] Exemplarily, the vacuumizing unit can adopt a vacuum pump, which can be in communication with the inside of the nitrogen replacement area through a pipeline, and can start to work when the inner sealing door 3 and the outer sealing door 4 are both closed. When the nitrogen replacement area is vacuumized to a certain degree, the vacuum pump stops working, and the nitrogen injection unit injects nitrogen in a nitrogen tank into the nitrogen replacement area.

[0030] It should be understood that the purpose of using nitrogen is to take advantage of the characteristics of nitrogen, which is stable and not easy to chemically react with other substances. In addition to nitrogen, other gases with similar properties, such as helium, can also be used.

[0031] In one possible embodiment, the inner window conveying unit 1 and the outer window conveying unit 2 each include a plurality of parallel rollers, which are synchronously driven and rotated by a conveying drive unit.

[0032] Exemplarily, the rollers can be in transmission with each other to transmit the drive, or a drive roller located below the rollers can be used for transmission. Whether direct transmission or drive roller transmission is used, the power for conveying is provided by a conveying motor to synchronously rotate each roller.

[0033] Further, in order to avoid slipping between the rollers and the reaction kettle, an anti-skid layer such as anti-skid rubber can be provided on the surface of the rollers, so that the rotation of the rollers can be smoothly transmitted to the reaction kettle.

[0034] Although the preferred embodiments of the present application have been described, those skilled in the art can make further changes and modifications to the embodiments once they know the basic inventive concept. Therefore, the appended claims are intended to be interpreted as including all the preferred embodiments and all the changes and modifications falling within the scope of the present application.

[0035] Obviously, those skilled in the art can make various modifications and variations to the present application without departing from the spirit and scope of the present application. Thus, if these modifications and variations of the present application fall within the scope of the claims of the present application and their equivalent technologies, the present application also intends to include these modifications and variations.
