These terms are only used to distinguish information of the same type from each other. For example, without departing from the scope of this application, the first information may also be referred to as the second information, and similarly, the second information may also be referred to as the first information.

[0021] In the description of this application, it should be understood that the terms "length", "width", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", etc., indicating the orientation or position relationship, are based on the orientation or position relationship shown in the accompanying drawings, and are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on this application.
[0022] Unless otherwise expressly specified or limited, terms such as "mounted," "connected," "connect," and "fixed" should be interpreted broadly. For example, they may refer to fixed or detachable connections, or integration; mechanical or electrical connections; direct or indirect connections through an intermediary; and internal communication between two components or interaction between two components. Those skilled in the art will understand the specific meanings of these terms in this application based on the specific circumstances.
[0023] In response to the above problems, an embodiment of the present application provides a pressurized hydrometallurgical continuous reaction experimental device. The technical solution of the embodiment of the present application is described in detail below with reference to the accompanying drawings.
[0024] like Figure 1 The pressurized hydrometallurgical continuous reaction experimental device shown includes: a reactor 1, a feed reactor 2, a pressure pump 3, a main connecting pipe 4, a gas cylinder 5, a main gas supply pipe 6, and a branch gas supply pipe 61;
[0025] In particular, multiple reactors 1 are provided, and the discharge end of the previous reactor 1 is connected to the feed end of the next reactor 1 via a main connecting pipe 4 to form a series connection. The feed end of the first reactor 1 is connected to the discharge end of the feed reactor 2 via the main connecting pipe 4. The main gas supply pipe 6 is connected to the gas cylinder 5, and the multiple reactors 1 and the feed reactor 2 are connected to the main gas supply pipe 6 via a branch gas supply pipe 61. The pressure pump 3 is connected to the first reactor 1 via an auxiliary connecting pipe 41.
[0026] It should be noted that: first, the reactor 1 is composed of two or more pressurized hydrometallurgical reactors of the same specifications and sizes connected in series, that is, the discharge port of the previous reactor is connected to the feed port of the next reactor through the main connecting pipe 4; second, the feeding kettle 2 is composed of one pressurized hydrometallurgical reactor, and its specifications and sizes are determined according to the continuous feeding time requirements of the feeding kettle 2. The size specifications are larger than those of the reactor 1, and the discharge port of the feeding kettle 2 is connected to the feed port of the first reactor through the main connecting pipe 4; third, the pressure provided by the pressure pump 3 needs to be greater than the maximum pressure in the reactor 1, and the flow rate must meet the flow requirements of the raw materials and / or auxiliary material slurry required for the experiment; fourth, the gas cylinder 5 contains one or more gases such as oxygen, air, nitrogen, carbon dioxide, etc. required for the experiment, and its pressure is higher than the maximum pressure of the reactor 1 and the feeding kettle 2.
[0027] In this manner, during use, raw material and / or auxiliary material slurry is added to the feed kettle 2. By controlling the pressure differential between the feed kettle 2 and the reactor 1, the raw material and / or auxiliary material slurry is fed into the first reactor 1. Simultaneously, the solution required for the reaction is pumped into the first reactor 1 using the pressure pump 3. The pressure within each reactor 1 is controlled to be the same, and a height difference is set between the reactors, with the first reactor at the highest position and each subsequent reactor positioned at a lower height. This height difference is utilized to ensure that the reaction solution and slurry within the reactors flow sequentially from the first reactor to the last reactor and out of the last reactor. During this time, the temperature within each reactor is controlled according to the reaction requirements, demonstrating the pressurized hydrometallurgical experimental process. By applying pressure to the gas cylinder 5, reactor 1, feed kettle 2, and pressure pump 3, the raw material and / or auxiliary material slurry can effectively prevent clogging of the pressure pump and pipelines, thus achieving a pressurized hydrometallurgical experiment.
[0028] In one embodiment, the feed kettle 2 is a container for raw material and / or auxiliary material slurry, so that a pressurized hydrometallurgical kettle can be used to replace the original raw material pressurized pump, reducing the blockage of the pressurized pump and pipeline by the raw material and / or auxiliary material slurry.
[0029] In one embodiment, for ease of control, a first shut-off valve 7, a flow controller 9, a first pressure gauge 8, and a first flow meter 10 are sequentially provided on each branch gas supply pipe 61 from the main gas supply pipe 6 to the kettle body. A thermometer 11 is provided on each reactor 1 and feed kettle 2. A second pressure gauge 81, a second flow meter 101, and a second shut-off valve 71 are sequentially provided on the auxiliary connecting pipe 41 directly from the booster pump 3 to the first reactor 1. A third shut-off valve 72, a pressure regulating valve 12, a third flow meter 102, and a third pressure gauge 82 are sequentially provided on the main gas supply pipe 6 from the gas cylinder 5 to the rear. A thermometer 11 is provided on each reactor 1 and feed kettle 2.
