Description

This invention relates to a reaction system and a cleaning method. A manufacturing system exists that produces a desired product by stirring or otherwise manipulating specified raw materials under specified environmental conditions. For example, Patent Document 1 discloses the following reaction apparatus. The reaction apparatus comprises a screw-feeder body which serves as a pressure reaction vessel, a catalyst supply unit for introducing a catalyst into the screw-feeder body, and a lower hydrocarbon supply unit for introducing lower hydrocarbons into the screw-feeder body. Furthermore, this reaction apparatus includes a screw for transporting the generated nanocarbon, a solid discharge unit for delivering the catalyst and nanocarbon transported by the screw, and a gas discharge unit for delivering the generated hydrogen outside the feeder body. Japanese Patent Publication No. 2006-290682 This is an overall diagram of the reaction system according to Embodiment 1.This is a block diagram of the reaction system according to Embodiment 1.This is a flowchart of the manufacturing process performed by the reaction system.This is a flowchart of the cleaning process performed by the reaction system.This diagram shows the flow of substances being processed in a reaction system.This is an overall diagram of the reaction system according to Embodiment 2.This is an overall diagram of the reaction system according to Embodiment 3. The present invention will be described below through embodiments, but the claims are not limited to these embodiments. Furthermore, not all configurations described in the embodiments are necessarily essential for solving the problem. For clarity, the following descriptions and drawings have been omitted and simplified as appropriate. In each drawing, the same elements are denoted by the same reference numerals, and redundant explanations have been omitted where necessary. <Embodiment 1> The overall configuration of the reaction system 1 according to this embodiment will be described with reference to Figure 1. Figure 1 is an overall configuration diagram of the reaction system 1. The reaction system 1 shown in Figure 1 produces products by subjecting a workpiece to a predetermined treatment. The products produced by the reaction system 1 are, for example, battery components such as solid electrolytes and positive electrode active materials used in sulfide-based all-solid-state lithium-ion secondary batteries. The predetermined treatment is not particularly limited as long as it is a means used in the process of changing the workpiece into a product, but for example it is a temperature change such as heating or cooling. The predetermined treatment is, for example it is stress transfer such as stirring, mixing, kneading, or grinding. The predetermined treatment is, for example it is a reaction involving the transfer of electrons or radicals. The predetermined treatment is, for example it is contact with a catalyst. When manufacturing battery components, reaction system 1 must perform each step under predetermined temperatures and atmospheres. The predetermined atmosphere is, for example, a dew point temperature of approximately minus 70 degrees Celsius. The predetermined temperature is, for example, between approximately 20 and 1000 degrees Celsius. Furthermore, during the manufacturing of battery components, hydrogen sulfide may be generated from the processed materials and products, or supplied to the reaction furnace. Therefore, reaction system 1 is required to perform the above manufacturing steps in an environment isolated from the outside air. Furthermore, while the reaction system 1 performs the manufacturing process to produce the aforementioned product, it is also configured to perform a cleaning process to clean the inside of the reaction system 1 when the manufacturing process is not being performed. The reaction system 1 maintains an environment isolated from the outside air while performing the manufacturing process. Therefore, even during the cleaning process, the reaction system 1 maintains an environment isolated from the outside air to prevent outside air from flowing into the internal air chamber, or to prevent toxic gases generated on the internal air chamber from leaking into the outside air chamber. The reaction system 1 primarily consists of a material input block 100 and a processing block 200. In the manufacturing process, the reaction system 1 receives a material container 10 through a material receiving port 101 in the material input block 100, and then inputs the material 10A sealed within the material container 10 into the processing block 200. Furthermore, in the washing process, the reaction system 1 performs washing by receiving a predetermined medium for washing. The material input block 100 has a material receiving space 110 covered by a blocking mechanism 111 that blocks the outside air from the inside air, and has a material receiving inlet 101 and a materia
