[0057] A preferred embodiment is given below, and the present invention is described more clearly and completely in conjunction with the accompanying drawings.

[0058] like Figure 1-Figure 2 As shown, this embodiment provides a reactor, which includes a material inlet 1, a reaction chamber 4, a pretreatment chamber 2 and a diversion part 3. The material inlet 1, the pretreatment chamber 2, the diversion part 3 and the reaction chamber 4 are sequentially connected along the height direction.

[0059] Specifically, a first material outlet 32 ​​and a second material outlet 31 are provided at the diversion portion 3, and the diversion chamber located inside the diversion portion 3 is connected to the reaction chamber 4 through the first material outlet 32. At the same time, the diversion chamber is connected to the outside through the second material outlet 31, and the opening and closing states of the first material outlet 32 ​​and the second material outlet 31 can be switched.

[0060] In this way, by further setting a diversion part 3 at the lower end of the pretreatment chamber 2, and setting a first material outlet 32 ​​and a second material outlet 31 on the diversion part 3, the purpose of material diversion can be achieved. Specifically, when the material enters the pretreatment chamber 2 from the material inlet 1 and is diverted in the diversion part 3, you can choose to close the first material outlet 32 ​​and open the second material outlet 31, so that the material can enter the outside directly from the second material outlet 31 after pretreatment; you can also choose to open the first material outlet 32 ​​and close the second material outlet 31, so that the material can enter the reaction chamber 4 from the first material outlet 32 ​​after pretreatment, and continue to react further in the reaction chamber 4. In this way, through the above structural settings, a single reactor can adapt to two different production and processing reaction processes.

[0061] In this embodiment, the reactor can be used for chemical reactions, the pretreatment step is physical crushing, and the main reaction step is heating reaction. Generally speaking, heating to about 300°C can meet most chemical reaction requirements. In application, an independent heating device (not shown in the figure) should be set to heat the reaction chamber 4. The heating device belongs to the existing technology, and the equipment that can adapt to the site can be directly purchased, such as electric heating equipment, heating oil heating equipment, etc. In other embodiments, the reactor can also be used for step-by-step reactions in other fields.

[0062] like Figure 4 As shown, in this embodiment, the reactor further includes a main stirring paddle 51, which is disposed in the reaction chamber 4. A scraper 53 is disposed on the main stirring paddle 51, and the scraper 53 is disposed close to the inner wall of the reaction chamber 4. In this way, the main stirring paddle 51 can stir the material in the reaction chamber 4 to promote the material to react as quickly as possible, and the scraper 53 can timely scrape off the material remaining on the inner wall of the reactor body, thereby further improving the reaction efficiency in the reaction chamber.

[0063] In this embodiment, since the pretreatment step does not require heating, most powder block materials are not easy to adhere to the pretreatment chamber 2 during the physical crushing process at room temperature; and the main reaction step is a heating reaction. After heating and stirring, the physical properties of the material are prone to change and become viscous, which is more likely to adhere, resulting in insufficient reaction and low yield. Therefore, the necessity of setting a scraper on the main stirring paddle is much greater than the necessity of setting a scraper on the pretreatment stirring paddle. However, if the conditions of the main reaction step change, the scraper may also be unnecessary. In addition, in other embodiments, multiple main stirring paddles and corresponding scrapers can be provided to adapt to the internal space of the reaction chamber.

[0064] In this embodiment, the reactor further includes a first motor 52, the driving shaft of the first motor 52 is connected to the main stirring paddle 51, and the first motor 52 is used to drive the main stirring paddle 51 to rotate. There are two flow splitters 3, and the first motor 52 is sandwiched between the two flow splitters 3. In this way, the integration of the reactor structure can be improved while driving the main stirring paddle 51.

[0065] In this embodiment, the first material outlet 32 ​​is located at the bottom of the diverter 3, and the second material outlet 31 is located at the side of the diverter 3 and at the side of the diverter 3 that is relatively away from the first motor 52. In this way, the streamline of the material can be prevented from interfering with the installation of the first motor 52, further improving the integration of the reactor structure.

[0066] In this embodiment, the reactor further includes a second motor 62 and a pretreatment stirring paddle 61, the pretreatment stirring paddle 61 is arranged in the pretreatment chamber 2, the driving shaft of the second motor 62 is connected to the pretreatment stirring paddle 61, and is located at one end of the pretreatment chamber 2 away from the reaction chamber 4, and the second motor 62 is used to drive the pretreatment stirring paddle 61 to rotate. In this way, the stirring treatment of the material in the pretreatment chamber 2 can be independent of the stirring treatment of the material in the reaction chamber 4.

[0067] like Figure 3 As shown, in this embodiment, the pretreatment stirring paddle 61 includes a crushing blade 611 and a stirring shaft 612, one end of the crushing blade 611 is connected to the stirring shaft 612, and the other end of the crushing blade 611 extends toward the inner wall of the pretreatment chamber 2. In this way, the material can be further stirred and crushed by the crushing blade 611 in the pretreatment chamber 2. In addition, in other embodiments, multiple pretreatment stirring paddles and corresponding crushing blades can be provided to adapt to the internal space of the pre-reaction chamber.

[0068] In this embodiment, the pretreatment stirring paddle 61 and the main stirring paddle 51 must be independent, because the speeds required for physical crushing and heating reaction are different, the former is about 1000r / min, and the latter is about 200-400r / min. In other embodiments, the structure and operating conditions in the pretreatment chamber and the reaction chamber need to be adjusted according to the reaction adaptability.

[0069] In this embodiment, the reactor further includes a temperature sensor 71, a controller 72, and a display screen 73. The temperature sensor 71 is located on the inner wall of the reaction chamber 4. The temperature sensor 71 and the display screen 73 are electrically connected to the controller 72. The display screen 73 and the controller 72 are located outside the reaction chamber 4. In this way, the temperature in the reaction chamber 4 can be monitored in time to better provide materials for reaction under certain temperature conditions. When the temperature is abnormal, it can be adjusted in time to ensure the normal progress of the reaction.

[0070] In this embodiment, the temperature sensor 71 is fixedly connected to the inner wall of the reaction chamber 4 by means of mounting screws (not shown in the figure). In other embodiments, other connection methods may also be used.

[0071] In this embodiment, the reactor further includes a first valve (not shown in the figure) and a second valve 92. The first valve is disposed at the first material outlet 32 ​​and is used to switch the opening and closing state of the first material outlet 32. The second valve 92 is disposed at the second material outlet 31 and is used to switch the opening and closing state of the second material outlet 31. In this way, the opening and closing switching of the first material outlet 32 ​​and the second material outlet 31 can be controlled with a relatively simple structure.

[0072] In this embodiment, the reactor further includes a third material outlet 41 and a third valve 93. The third material outlet 41 is located at one end of the reaction chamber 4 away from the pretreatment chamber 2. The third valve 93 is disposed at the third material outlet 41 and is used to switch the opening and closing states of the third material outlet 41. In this way, the output of the material in the reaction chamber 4 can be controlled with a relatively simple structure.

[0073] In this embodiment, the reactor further includes a bracket, which includes a clamping plate 81 disposed around the reaction chamber 4 and legs 82 fixed to the clamping plate 81, the legs 82 supporting the clamping plate 81, and all the legs 82 disposed around the third material outlet 41. In this way, while facilitating the output of the material in the reaction chamber 4, a stable support can be provided for the reactor, so that it can be stably erected in a safe position as a fixed device. In this embodiment, the number of legs 82 is 4; in other embodiments, the number of legs can be adjusted to other numbers that can make the reactor as a whole stable.

Those skilled in the art can make various changes or modifications to these implementations without departing from the principle and essence of the utility model, but these changes and modifications fall within the protection scope of the utility model.
