Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] Example

[0021] See also Figure 1-Figure 3, a centrifugal extractor for zirconium and hafnium production with stable operation shown in the figure includes a shell 1, a sealing cover 2 is provided on the top of the shell 1, a motor 3 is fixedly connected to the top of the sealing cover 2, the motor 3 is plugged into a rotating shaft 4, the rotating shaft 4 is fixedly connected to a drum 5, an impeller assembly 6 is provided below the drum 5, the impeller assembly 6 includes an impeller cover 601, an impeller 602 is provided at the central axis of the impeller cover 601, a connecting shaft 603 is provided at the central axis of the impeller 602, the connecting shaft 603 is fixedly connected to a guide plate 7, and the guide plate 7 is fixedly connected to the rotating shaft 4. The utility model is provided with a drum inside the shell, a rotating shaft is provided inside the drum, and an impeller assembly is provided below the drum. The impeller assembly consists of an impeller cover and an impeller, and the impeller is located at the central axis of the impeller cover. When the drum rotates, the impeller will also rotate accordingly, generating a strong stirring force, thereby effectively mixing and crossing the solution at the bottom of the shell, thereby improving the extraction effect.

[0022] Furthermore, a group of liquid inlet ends 101 are opened on the outside of the shell 1, a liquid outlet end 102 is provided above the liquid inlet end 101, a liquid outlet end 2 103 is provided above the liquid outlet end 102, and a fixed block 104 is provided inside the shell 1. A group of liquid inlet ends are opened through the outside of the shell, and the liquid inlet ends enable the solution to be conveniently and quickly injected into the interior of the device. Secondly, the liquid outlet end 1 and the liquid outlet end 2 located above the liquid inlet end are respectively used for discharging different stages or different types of extraction liquids, so that the outflow of the solution can be flexibly controlled during the extraction process, meeting different experimental or production requirements, and effectively avoiding the confusion of solutions in different extraction stages, thereby ensuring the accuracy and purity of the extraction results.

[0023] Furthermore, the fixed block 104 is rotatably connected to the drum 5, and a partition plate 501 is provided on the top of the drum 5. Below the partition plate 501 is liquid outlet bin 1, and above the partition plate 501 is liquid outlet bin 2. The rotational connection between the fixed block and the drum ensures that the drum can rotate stably under the support of the fixed block, thereby maintaining the smooth progress of the extraction process. The partition plate provided on the top of the drum effectively divides the internal space of the drum into two independent chambers: liquid outlet bin 1 and liquid outlet bin 2. The partition design makes it possible to simultaneously separate two different solutions or different processing stages of the same solution during the extraction process, thereby greatly improving the extraction efficiency and flexibility.

[0024] Furthermore, a liquid outlet pipe 401 is provided inside the rotating shaft 4, and a liquid outlet plate 402 is provided on the top of the rotating shaft 4. The liquid outlet plate 402 is fixedly connected to the dividing plate 501. The liquid outlet pipe is cleverly arranged inside the rotating shaft. By arranging the liquid outlet pipe inside the rotating shaft, internal transportation of the solution is realized. The liquid outlet plate arranged on the top of the rotating shaft is fixedly connected to the dividing plate, so that the liquid outlet plate can rotate with the rotating shaft and the dividing plate, thereby ensuring the continuity and uniformity of the liquid outlet. At the same time, the liquid outlet plate effectively controls the flow direction and flow rate of the solution, avoiding waste and confusion of the solution.

[0025] Furthermore, one end of the liquid outlet pipe 401 passes through the rotating shaft 4 to connect to the liquid outlet bin 1, and one end of the liquid outlet pipe passes through the rotating shaft to connect to the liquid outlet bin 1. The liquid outlet pipe is directly connected to the liquid outlet bin 1 and dynamically operates with the rotation of the rotating shaft. It can continuously and stably draw out the solution in the liquid outlet bin 1, thereby ensuring the continuity of the extraction process and improving production efficiency.

[0026] Furthermore, the impeller cover 601 is provided with a plurality of liquid inlet holes, and the impeller cover 601 is frictionally connected to the outer wall of the drum 5. Through the plurality of liquid inlet holes provided on the impeller cover and the friction connection between the impeller cover and the outer wall of the drum, the plurality of liquid inlet holes provided on the impeller cover effectively increases the flow area of ​​the solution, so that more solution can quickly enter the impeller cover, ensuring the full mixing of the solution during the extraction process, thereby improving the extraction effect. At the same time, the friction connection between the impeller cover and the outer wall of the drum enhances the integrity of the equipment, and effectively prevents the solution from leaking between the two, ensuring the sealing and purity of the extraction process.

[0027] Furthermore, the bottom of the impeller cover 601 is fixedly connected to the interior of the outer shell 1, and a group of liquid inlet ends 101 are provided on both sides of the impeller cover 601. The fixed connection between the bottom of the impeller cover and the interior of the outer shell, as well as a group of liquid inlet ends provided on both sides of the impeller cover, ensures the structural stability and safety of the equipment, and will not loosen or shift due to the operation of the equipment or the influence of external factors. The group of liquid inlet ends provided on both sides of the impeller cover allows the solution to be easily introduced from the outside of the equipment into the inside of the impeller cover, providing necessary material input for the extraction process. At the same time, the position and design of the liquid inlet end also take into account the uniformity and stability of the solution flow, which helps to ensure the quality and efficiency of the extraction process.

[0028] Furthermore, the impeller 602 is rotatably connected to the inside of the impeller cover 601 through the rotating shaft 4 and the connecting shaft 603. The impeller is rotatably connected to the inside of the impeller cover through the rotating shaft and the connecting shaft, thereby ensuring the stable rotation of the impeller inside the impeller cover. The uniformity and consistency of the extraction process are crucial, and uneven mixing or decreased extraction efficiency due to unstable rotation of the impeller is prevented.

[0029] Secondly, through the rotational connection between the rotating shaft and the connecting shaft, the impeller can rotate freely inside the impeller cover, effectively stirring and mixing the solution, improving the mixing efficiency of the solution, ensuring the uniform distribution of the solute during the extraction process, and thus improving the extraction effect.

[0030] In this scheme, the working process is: the rotating shaft is driven by the motor, which in turn drives the drum and impeller assembly to rotate at high speed. During the rotation process, the solution enters the equipment through the liquid inlet on the outer shell, first flows through the impeller cover, and is initially mixed and stirred by the impeller. Subsequently, the solution is subjected to a strong centrifugal force in the drum to separate zirconium and hafnium from other substances.

[0031] The partition plate inside the drum divides the drum into two independent chambers: liquid outlet chamber 1 and liquid outlet chamber 2, which are used to collect the extracts at different stages. The liquid outlet pipe inside the rotating shaft is responsible for draining the extracts from liquid outlet chamber 1. During the whole process, the sealing cover ensures the sealing of the equipment to prevent solution leakage.
