[0020] During use: Workers control the feeding device 2 and the liquid conveying device 4 to respectively complete the automatic conveying of solid raw materials and liquid raw materials. When the solid raw materials and liquid raw materials added to the stirring chamber 11 reach a certain amount, the feeding device 2 and the liquid conveying device 4 are stopped. When it is necessary to convey solid raw materials or liquid raw materials into the stirring chamber 11 again, the feeding device 2 and the liquid conveying device 4 are restarted. When the amount of solid raw materials in the feeding device 2 is almost consumed, the supply device 3 can be started to supplement solid raw materials for the feeding device, so that the feeding device 2 can complete the automatic conveying of solid raw materials again; In this way, the automatic conveying of solid raw materials and liquid raw materials can be controlled, the problem of inconvenient manual feeding of raw materials is solved, and the production efficiency is improved.

[0021] For the specific structure of the reaction container 1, reference can be made to Patent CN202121612044.1, which will not be elaborated in this embodiment.

[0022] Preferably, the feeding device 2 includes a hopper 21 and a quantitative conveying mechanism 22 provided at the bottom of the hopper 21. The quantitative conveying mechanism 22 is arranged on the top of the reaction container 1. The quantitative conveying mechanism 22 is used to quantitatively convey the solid raw materials in the hopper 21 into the stirring chamber 11. The supply device 3 is connected to the hopper 21; The quantitative conveying mechanism 22 includes a metering valve 221 provided at the bottom of the hopper 21 and a driving motor 222 for driving the metering valve 221. The metering valve 221 is connected to the top of the reaction container 1;

[0023] Specifically, the hopper 21 is used to store solid raw materials. When it is necessary to convey solid raw materials to the stirring chamber 11, the operation of the metering valve 221 is driven by the driving motor 222, so that the solid raw materials in the hopper 21 are quantitatively conveyed into the stirring chamber 11. When the solid raw materials in the hopper 21 are almost consumed, the feeding device can be started to complete the supplement of solid raw materials in the hopper 21.

[0024] More preferably, the feeding device 3 includes a storage tank 31 for storing solid raw materials and a delivery pump 32 disposed on the top of the reaction container 1. The delivery pump 32 is provided with a first feed pipe 321 and a first discharge pipe 322. The first feed pipe 321 is connected to the storage tank 31, and the first discharge pipe 322 is connected to the hopper 21. The delivery pump 32 is configured to transport the solid raw materials in the storage tank 31 to the hopper 21;

[0025] Specifically, when the solid raw materials in the hopper 21 are almost consumed and the quantitative delivery of the fixed raw materials cannot be completed, the delivery pump 32 is controlled to extract the solid raw materials in the storage tank 31. After the solid raw materials flow through the first feed pipe 321 and the first discharge pipe 322, they enter the hopper 21, thereby completing the replenishment of the solid raw materials in the hopper 21.

[0026] In this embodiment, the liquid delivery device 4 includes a liquid storage tank 41 for storing liquid raw materials and a metering pump 42 disposed on the top of the reaction container 1. The metering pump 42 is provided with a second feed pipe 422 and a second discharge pipe 421. The second feed pipe 422 is connected to the liquid storage tank 41, and the second discharge pipe 421 communicates with the stirring chamber 11. The metering pump 42 is configured to quantitatively transport the liquid raw materials in the liquid storage tank 41 to the stirring chamber 11;

[0027] Specifically, the delivery of the liquid raw materials is completed by the metering pump 42. The second discharge pipe 421 communicates with the stirring chamber 11, and the second feed pipe 422 is connected to the liquid storage tank 41. When it is necessary to replenish the liquid raw materials to the stirring chamber 11, the metering pump 42 is started to quantitatively extract the liquid raw materials in the liquid storage tank 41, so that the liquid raw materials will enter the stirring chamber 11 of the reaction container 1.

[0028] Preferably, it further includes a cover 211 covering the top of the hopper 21, and the first discharge pipe 322 is connected to the cover 211; the cover 211 can effectively prevent external impurities and dust from entering the interior of the hopper 21, keep the raw materials clean and pure, and avoid contaminating the raw materials.

[0029] In this embodiment, the cover 211 is transparent; the transparent cover 211 can facilitate the staff to observe the situation in the hopper 21 and avoid accidents.

[0030] In this embodiment, it further includes a rotary feeding mechanism 5, which is arranged between the top of the reaction container 1 and the quantitative conveying mechanism 22. The rotary feeding mechanism 5 is used to disperse and feed the solid raw materials conveyed by the quantitative conveying mechanism 22 so that the solid raw materials are dispersed in the stirring chamber 11. There is a feeding hole (not shown in the figure) at the top of the reaction container 1. The rotary feeding mechanism 5 includes a mounting seat 51 covering the feeding hole, a rotary motor 52 arranged on the mounting seat 51, and a feeding plate 53 arranged on the rotating shaft of the rotary motor 52. The axis of the rotating shaft of the rotary motor 52 is horizontally arranged, and the quantitative conveying mechanism 22 is arranged on the top of the mounting seat 51.

[0031] Specifically, after the quantitative conveying mechanism 22 conveys the solid raw materials into the stirring chamber 11, in order to prevent the solid raw materials from accumulating at the same position in the stirring chamber 11 and affecting the stirring effect, the mounting seat 51 is covered on the feeding hole. During the process of the quantitative conveying mechanism 22 conveying the solid raw materials, the solid raw materials first enter the mounting seat 51. Then, the rotary motor 52 drives the feeding plate 53 to rotate repeatedly counterclockwise and clockwise. After changing the movement path of the fixed raw materials, they fall into the stirring chamber 11, thereby dispersing the solid raw materials into the stirring chamber 11 to improve the reaction efficiency and effect during the stirring process.

[0032] Although the embodiments of the present invention have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the claims and their equivalents.
