Description

Technical Field

[0001] This utility model belongs to the field of rare earth extraction technology, specifically relating to a rare earth extraction tank equipped with a simple exhaust device. Background Technology

[0002] In existing processes, the aqueous phase inlet of the extraction tank is only equipped with an aqueous phase regulating pipe and a reflux pipe. Due to the high internal temperature of the rare earth extraction tank at the production site, the aqueous phase carries water vapor and a small amount of volatile organic solvents. This gas can easily cause negative pressure to form at the connection between the aqueous phase inlet and the submerged chamber. The stirring force can cause the submerged chamber to deform, leading to the production line stopping. Utility Model Content

[0003] The purpose of this invention is to provide a rare earth extraction tank equipped with a simple exhaust device, which can promptly discharge the gas entrained in the aqueous phase, ensuring the flow of the aqueous phase and the normal operation of the extraction tank.

[0004] The technical solution is as follows: A rare earth extraction tank equipped with a simple venting device includes: an extraction tank, a submersible chamber, an aqueous phase box, an aqueous phase regulating pipe, and a venting pipe. The extraction tank includes: an extraction tank body and a top cover. The top cover is installed on top of the extraction tank body. The extraction tank body is a box structure with an open top. A first partition is provided on the lower inner wall, and a second partition is provided at the bottom of the top cover. The first partition is located to the right of the second partition, and the lower edge of the second partition is lower than the upper edge of the first partition. The gap between the first and second partitions is an overflow channel. The submersible chamber is located to the right of the first partition, and its top is connected to the bottom of the top cover. A cover plate is connected between the top of the first partition and the submersible chamber. The cover plate has a cover plate through hole, and the aqueous phase regulating pipe is connected to the cover plate through hole. The venting pipe is connected to the inner wall of the aqueous phase regulating pipe. The space enclosed by the first partition, the horizontal plate, and the submersible chamber is the aqueous phase box.

[0005] Furthermore, a through hole is provided at the bottom of the submersible chamber, and the bottom of the submersible chamber is located above the bottom of the extraction tank body. A stirrer is provided inside the submersible chamber, and a first drain port and a second drain port are provided on the right outer wall of the submersible chamber, with the second drain port located above the first drain port.

[0006] Furthermore, the exhaust pipe passes through the water phase regulating pipe, and multiple exhaust holes are evenly distributed on the outer wall of the exhaust pipe.

[0007] Furthermore, a support block is provided on the outer wall of the exhaust pipe, and the support block is connected to the top of the water phase regulating pipe.

[0008] Furthermore, the top of the exhaust pipe is located above the water phase regulating pipe.

[0009] This utility model has the following advantages compared with the prior art: 1. This utility model overcomes the problems of gas entrainment in the aqueous phase and evaporation of organic solvents. It adopts an automatic venting method for the aqueous phase pipe, which can promptly discharge the gas entrained in the aqueous phase, ensuring the flow of the aqueous phase and the normal operation of the extraction tank.

[0010] This utility model features a simple and reasonable structure. The exhaust pipe effectively reduces gas levels within the aqueous phase chamber, ensuring the flow of the aqueous phase and the normal operation of the extraction tank. An exhaust pipe is installed inside the aqueous phase regulating pipe, automatically venting gas entrained in the aqueous phase and facilitating its flow. This exhaust pipe ensures the smooth flow of the aqueous phase and the normal operation of the extraction tank and submerged chamber, thus improving work efficiency.

[0011] The temperature inside the existing extraction tank is high, and the aqueous phase contains water vapor and a small amount of volatile organic solvents. This gas can easily cause negative pressure to form at the connection between the aqueous phase inlet and the submersible chamber. The stirring and pumping force can cause deformation of the submersible chamber and halt the production line.

[0012] 2. The tank structure of this utility model is stable, simple and practical, with low manufacturing cost and high reliability, ensuring the stability of use. It is also simple and easy to operate and can be used on a large scale. Attached Figure Description
