At present, various reaction vessels are used for preparing positive and negative electrode materials, for example, mullite sagger and corundum sagger are mainly used as charging vessels in the production process of ternary, lithium cobaltate, lithium manganate and other positive electrode materials, and graphite sagger is mainly used as charging vessels in the production process of graphite negative electrode materials. In addition, the reaction kettle is also commonly used as a liquid phase reaction vessel in the new energy industry.

However, a new method of manufacturing an anode material has appeared, which involves a high-temperature gasification reaction of raw materials, and there is a case where a part of the high-temperature gasified raw materials must be in excess in mass. Therefore, a reactor which has a sealing function and can withstand a high temperature of 500 ℃ or more as a whole is required, and it is preferable that the reactor can separate the reaction product from the excess raw material. The sagger is open, does not have a high-temperature sealing function, and can not directly separate raw materials and finished products which do not participate in the reaction; the reaction kettle cannot be used in a high-temperature environment of more than 500 ℃, and cannot directly separate a product from excessive raw materials and byproducts, so that a subsequent separation process is required.

Therefore, it is necessary to provide a reactor in which excessive reaction raw materials and finished products do not need to be separated after the reaction is completed, and the reaction raw materials undergo a high-temperature gasification reaction.

referring to fig. 1, the reactor according to an embodiment of the present disclosure includes at least two tanks 10, a cover 20, and at least one connecting pipe 30. The tank body 10 has an opening, the cover body 20 is disposed on the tank body 10, the cover body 20 is used for closing or opening the opening of the tank body 10, and two ends of the connecting pipeline 30 are respectively connected with one tank body 10.

Thus, the reactor has a sealing function by providing the lid body 20 covering the can body 10, and is applicable to a material for which a gasification reaction occurs; on the other hand, by arranging at least two tank bodies 10 and arranging the raw materials with excessive mass and other reaction materials in different tank bodies 10, the raw materials with excessive mass are subjected to high-temperature gasification reaction, then enter other tank bodies 10 in a gas state through the connecting pipeline 30, and react with the reaction materials in other tank bodies 10 to generate finished products, and after the reaction is finished, all the products obtained in other tank bodies 10 are the required finished products of the negative electrode materials, so that the finished products separated in different tank bodies 10 and the raw materials with excessive mass are obtained, impurity removal procedures of the finished products are reduced, and the industrial production cost is reduced.

In some embodiments of the present application, the material of the tank 10 and the connecting line 30 includes at least one of stainless steel, ceramic, copper, carbon steel, and cast iron. The reactor can resist 0-30 MPa pressure and can be used in the temperature environment of more than 500 ℃ by setting the tank body 10 and the connecting pipeline 30 to be at least one of the materials, so that the applicability of the reactor to different reaction materials and different reaction conditions is improved.

In some embodiments, the connection between the can body 10 and the cover 20 is a flange connection or a snap connection. Through flange connection or buckle connection between the tank body 10 and the cover body 20, the tank body 10 can be tightly combined with the cover body 20, and meanwhile, the flange connection and the buckle connection have the advantage of convenience in disassembly, so that the tank body 10 and the cover body 20 are simple to separate, and reaction material in the tank body 10 can be conveniently put into or taken out before and after reaction. Further, the connection mode that the jar body 10 and the connecting line 30 adopted is flange joint or buckle connection, makes the reactor easily produce, assemble, dismantle and deposit, improves user's convenience of use.

In some embodiments of the present application, the reactor further comprises a first seal and/or a second seal. The first sealing element is arranged at the joint of the tank 10 and the connecting pipeline 30, and the second sealing element is arranged at the joint of the tank 10 and the cover 20. By arranging the first sealing element and the second sealing element, when the gasification reaction occurs in the tank body 10, gas products are prevented from escaping from the connecting positions of the tank body 10 and the connecting pipeline 30 and the connecting positions of the tank body 10 and the cover body 20, so that the reactor is suitable for reaction materials for the gasification reaction; while enabling gaseous products to enter the other tank 10 through the connecting line 30. Further, the first sealing element and the second sealing element are made of at least one of metal, asbestos, graphite and high-temperature sealant. Because the asbestos, the graphite and the high-temperature sealant have the characteristic of high temperature resistance, a user can adopt one material or metal with high-temperature resistance to realize the sealing of the joint, or can adopt a compound of the asbestos, the graphite and the metal according to actual needs, and can also use the high-temperature sealant and sealing elements made of other materials in a combined way to meet various use requirements.

In some embodiments, as shown in FIG. 1, the connecting line 30 is a straight line type line. Therefore, each part of the reactor has simple structure and is convenient for production.

FIG. 2 is a schematic diagram of a reactor according to another embodiment of the present application.

Referring to fig. 2, in some embodiments of the present application, the connecting line 30 is configured in an inverted V shape. Through the connecting pipeline 30 that is the type of falling V that sets up, make when the reactor is emptyd, if the partial material in the jar body 10 gets into connecting pipeline 30, then this partial material can be restricted in the turning point department of the type of falling V connecting pipeline 30, can't get into other jar bodies 10 to prevent to get the material in-process after the reaction finishes, the material in the different jar bodies 10 mixes, consequently has avoided the edulcoration process. It is understood that in other embodiments of the present application, the connecting line 30 may be configured in a V-shape or a curved shape, and the non-straight-through type of the connecting line 30 is provided to prevent other materials from being mixed when the product is poured out.

FIG. 3 is a schematic view of the structure of a reactor according to still another embodiment of the present invention.

Referring to fig. 3, in some embodiments of the present application, the reactor further comprises a pipe connection 40; the connecting line 30 includes a first line 32 and a second line 34, and a pipe connector 40 is coupled between the first line 32 and the second line 34 for connecting or disconnecting the first line 32 and the second line 34. By arranging the pipeline connecting piece 40, the first pipeline 32 and the second pipeline 34, when a reaction occurs, the first pipeline 32 is communicated with the second pipeline 34, and a gas product in one tank body 10 sequentially passes through the first pipeline 32 and the second pipeline 34 to enter other tank bodies 10; when the reaction is completed, the user can separate the first pipe 32 from the second pipe 34 by removing the pipe connection 40, so as to take out the materials in different tanks 10 separately.

In some embodiments, the pipe connection 40 is a flanged connection or a snap connection with the first pipe 32 and the second pipe 34.

In some embodiments of the present application, as shown in FIG. 1, the connecting line 30 is one, and the reactor comprises a first tank 12 and a second tank 14. The second tank 14 is connected to the first tank 12 by means of a connecting line 30. The method comprises the steps of placing excessive reaction raw materials in a first tank 12, placing other reaction materials in a second tank 14, heating the first tank 12 to enable the raw materials to generate gasification reaction, enabling the gaseous raw materials to enter the second tank 14 through a connecting pipeline 30, generating reaction for generating the cathode materials in the second tank 14, completing the reaction after all the reaction materials in the second tank 14 participate in the reaction, obtaining the required cathode material finished product in the second tank 14, and obtaining the excessive reaction raw materials in the first tank 12.

As shown in fig. 4, the present application further provides a method for manufacturing a negative electrode material, in which the reactor according to any of the above embodiments is applied, and the method for manufacturing the negative electrode material includes:

s110: placing a predetermined mass of raw material in one can 10 and placing a reactive material in another can 10 connected to the can 10;

specifically, the raw material can be used for producing an anode material of a battery anode, and the raw material can be gasified at a high temperature and react with a reaction material under a specific condition to generate the anode material. In the case where the reaction between the raw material and the reaction material is carried out at a high temperature, if the mass of one of the materials is regarded as a fixed amount, the mass of the other material is also regarded as a fixed amount. In actual production, in order to ensure that the reaction is sufficient, the actual mass of the raw materials is generally larger than the theoretical mass under the theoretical condition, and if the mass of the reaction materials actually participating in the reaction is T1, the mass of the raw materials actually participating in the reaction is T2, and the preset mass T3 placed in the tank body is adopted, then T3 is more than T1.

S120: the can body 10 containing the raw material is heated to form a negative electrode material in the other can body 10.

It can be understood that the raw material of the negative electrode, which is gasified when heated to a certain temperature, is introduced into the other can body 10 through the connection pipe 30 in a gaseous state, and reacts with the reaction material in the other can body 10. After the reaction of all the reaction materials is completed, all the negative electrode material finished products are in the other can body 10, and the rest of the raw materials are in the can body 10 for containing the raw materials. Thus, after the reaction is completed, the required cathode material product and the residual excessive raw materials are placed in different tank bodies 10, so that finished products without impurities can be directly obtained, and impurity removal procedures are avoided.

The technical features of the embodiments described above may be arbitrarily combined, and for the sake of brevity, all possible combinations of the technical features in the embodiments described above are not described, but should be considered as being within the scope of the present specification as long as there is no contradiction between the combinations of the technical features.

The above-mentioned embodiments only express several embodiments of the present application, and the description thereof is more specific and detailed, but not construed as limiting the scope of the invention. It should be noted that, for a person skilled in the art, several variations and modifications can be made without departing from the concept of the present application, which falls within the scope of protection of the present application.
