[0025] It should be noted that the following detailed description is exemplary, and is intended to provide further explanation of the utility model. Unless otherwise indicated, all technical and scientific terms used in the utility model have the same meaning as generally understood by those skilled in the art to which the utility model belongs.

[0026] Example 1:

[0027] The embodiment provides a kind of automatic feeding device of bar-shaped metal sodium, as shown in Figure 1 And Figure 2 Including bunker, barrel 2, feeding pipeline 10 etc., the bottom of bunker is equipped with feeding port 6, multiple rotatable barrel 2 are arranged in bunker, when barrel 2 rotates to with feeding port 6 corresponding, bar-shaped metal sodium added to barrel 2 falls into feeding pipeline 10 through feeding port 6, and feeding is realized to reactor by feeding pipeline 10;Above-mentioned process is carried out under sealed condition.

[0028] Specifically, bunker includes bunker main body 1 and top cover 7, top cover 7 is rotationally connected to the top of bunker main body 1, can be opened and closed relative to bunker main body 1, after top cover 7 is closed with bunker main body 1, the closed environment is formed in bunker main body 1.The cross-sectional shape of bunker main body 1 can be set according to actual demand, in the embodiment, the cross section of bunker main body 1 is circular.

[0029] Feeding port 6 is opened in the bottom of bunker main body 1 near edge position, i.e. eccentricity is set relative to the center of bunker main body 1, both can guarantee the correspondence of position with barrel 2, can also leave the installation space of drive motor 8.Feeding port 6 is communicated with the top end of feeding pipeline 10, the bottom end of feeding pipeline 10 is discharge port 12, and discharge port 12 is used to connect reactor.Feeding pipeline 10 installs observation window 9 in the pipe section close to feeding port 6, to facilitate observation whether bar-shaped metal sodium falls normally.

[0030] As shown in Figure 1 And Figure 2As shown, the silo is provided with a plurality of barrels 2, which are uniformly distributed around the center of the silo body 1, and the number of barrels 2 is determined according to the actual feeding requirements, for example, eight barrels 2 are provided; the plurality of barrels 2 are synchronously rotated by a rotating mechanism, and feeding can be realized when any barrel 2 corresponds to the feeding port 6.

[0031] In this embodiment, the rotating mechanism includes a driving motor 8 and a support 4, which is arranged at the center of the silo body 1 and is arranged in the vertical direction, and the barrels 2 are fixed to the support 4 through connecting rods 3; the bottom of the support 4 is connected to the driving motor 8, which drives the rotation of the support 4 and each barrel 2. It can be understood that in other embodiments, the rotating mechanism can also be realized by other ways, for example, each barrel 2 is fixed to a turntable, and the turntable is connected to the driving motor 8.

[0032] The height of the barrel 2 is slightly lower than the height of the silo body 1, so that the barrel 2 can rotate relative to the silo body 1. The top of the barrel 2 is open, and the bottom is installed with a baffle 5 through a hinge 13, and the shape of the baffle 5 is adapted to the cross section of the barrel 2. Figure 3 and Figure 4 As shown, the bottom of the baffle 5 is installed with a roller 14, which is used to support the baffle 5 when the baffle 5 is in the closed state, so that the baffle 5 can be tightly attached to the bottom of the barrel 2, and the barrel 2 will not contact the bottom surface of the silo body 1 when rotating, avoiding friction.

[0033] In this embodiment, one roller 14 installed at the bottom of each baffle 5 can realize the supporting effect; of course, in other embodiments, the number of rollers 14 can be adjusted according to actual requirements.

[0034] The size of the feeding port 6 is larger than that of the baffle 5, when the barrel 2 does not correspond to the feeding port 6, the bottom roller 14 of the barrel 2 contacts the bottom surface of the silo body 1, which limits the baffle 5; when the barrel 2 corresponds to the feeding port 6, the baffle 5 is released, and the rod-shaped metal sodium falls into the feeding pipeline 10. After the rod-shaped metal sodium is put into each barrel 2, under the action of the rotating mechanism, each barrel 2 corresponds to the feeding port 6 one by one, realizing batch feeding.

[0035] As shown, Figure 1 The cross section of the barrel 2 is elliptical, similar to the cross section of the rod-shaped metal sodium, slightly larger than the cross section size of the rod-shaped metal sodium, which can ensure that the rod-shaped metal sodium remains in the vertical state in the barrel 2, avoiding the situation that the rod-shaped metal sodium is stuck in the barrel 2 and cannot fall.

[0036] As shown, Figure 2As shown, the feeding pipeline 10 is connected to a nitrogen protection system, which comprises a gas pipeline 11 connected to a vacuum pump and a nitrogen device to realize nitrogen sealing protection, block the feeding device from contacting air and moisture outside, and avoid the flammable and explosive gas produced by the contact of metal sodium with water or alcohol from mixing with air to reach the explosion limit, thus causing safety hazards. Before the rod-shaped metal sodium is put into the device, the vacuum pump is opened to extract air from the feeding device, and then the vacuum pump is closed and the nitrogen device is opened to fill the closed environment formed by the bin and the top cover 7 with nitrogen; the nitrogen pressure is 1-10 kPa.

[0037] The working principle of the embodiment is as follows:

[0038] The top cover 7 is opened, the rod-shaped metal sodium is added into each barrel 2, and the top cover 7 is closed; the nitrogen protection system and the rotating mechanism are opened, the driving motor 8 is rotated to drive the bracket 4 and the barrel 2 to rotate together, and when any barrel 2 rotates to the feeding opening 6, the bottom baffle 5 loses support and the rod-shaped metal sodium falls due to gravity, enters the reaction kettle through the feeding opening 6, the feeding pipeline 10 and the discharge opening 12.

[0039] The driving motor 8 is controlled by a control system, which can realize automatic and continuous feeding, reduce labor intensity, and also can realize intermittent feeding to maintain the material concentration in the reaction liquid above the lower limit.
