Description

Technical Field

[0001] This utility model relates to the field of extraction equipment technology, specifically to an extraction device for purifying phosphorus-containing polyvalent salts. Background Technology

[0002] In the purification process of phosphorus-containing polyvalent salts, extraction and separation is the core step. Its purpose is to remove impurity ions such as calcium, magnesium, and silicon contained in the raw materials to ensure that the purity of the final product meets the requirements of high-end fields such as battery materials and food additives.

[0003] Existing extraction devices for purifying phosphorus polyvalent salts mostly have fixed impeller motors. When the impeller wears out, gets stuck, or needs to be replaced for different materials, a large number of connecting parts need to be disassembled. This is not only cumbersome but also leads to prolonged equipment downtime and affects purification efficiency. When the height of the mixing tank needs to be adjusted, manual operation with the help of external lifting equipment is required, which is difficult and unsafe, and cannot meet the requirements of modern continuous production for equipment flexibility and convenience. Therefore, to address these shortcomings, we propose an extraction device for purifying phosphorus polyvalent salts. Utility Model Content

[0004] The purpose of this utility model is to provide an extraction device for purifying phosphorus-containing polyvalent salts, in order to solve the problems mentioned in the background art. The impeller motors of existing extraction devices for purifying phosphorus-containing polyvalent salts are mostly fixedly installed. When the stirring impeller is worn, jammed, or needs to be replaced for different materials, a large number of connecting parts need to be disassembled. This is not only cumbersome to operate, but also leads to prolonged equipment downtime and affects purification efficiency. When it is necessary to adjust the height of the mixing tank, manual assistance with external lifting equipment is required, which is difficult to operate and has low safety. It is difficult to meet the needs of modern continuous production for equipment flexibility and convenience.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an extraction device for purifying phosphorus-containing polyvalent salts, comprising a base, a first connecting plate fixedly disposed on one side of the top of the base, a linear pushing mechanism fixedly disposed on the top of the first connecting plate, an output end of the linear pushing mechanism fixedly connected to one end of a connecting block, a mixing tank fixedly disposed in the middle of the connecting block, a top cover detachably fixedly disposed on the top of the mixing tank, a feeding port penetrating one side of the top of the top cover, a discharge port penetrating the bottom of the mixing tank, an impeller motor fixedly disposed on the top of the top cover, and the impeller motor connected to a stirring impeller at the bottom of the top cover via a coupling.

[0006] Preferably, the linear actuation mechanism includes a motor support, a motor, a slider, a lead screw, and a sliding rod. The slider is the output end of the linear actuation mechanism and is fixedly connected to one end of the connecting block. Multiple sliding rods are symmetrically fixedly provided on the top of the first connecting plate. The top ends of the multiple sliding rods are fixedly connected to the motor support. A motor is fixedly provided at the middle position of the top of the motor support. The output shaft at the bottom of the motor is connected to the lead screw through a coupling. The outer surface of the lead screw is threaded with a slider. Sliding rods are slidably connected through both sides of the slider. The lead screw is connected to the first connecting plate through a bearing.

[0007] Preferably, a second connecting plate is fixedly provided on the other side of the top of the base, and multiple sets of auxiliary sliding rods are symmetrically fixedly provided on the top of the second connecting plate. An auxiliary slider is slidably connected to the auxiliary sliding rod, and one end of the auxiliary slider is fixedly connected to the other end of the connecting block.

[0008] Preferably, a limiting groove is provided through the bottom end of the top cover, and a first connecting block is fixedly provided at both ends of the top cover. A bolt is threadedly connected to the first connecting block. A second connecting block is fixedly provided at both ends of the mixing groove. A threaded hole is provided through the second connecting block. A limiting ring and a rubber sealing ring are fixedly provided at the top end of the mixing groove. The diameter of the rubber sealing ring is larger than that of the limiting ring. The limiting ring of the mixing groove is inserted into the limiting groove of the top cover. The bolt of the first connecting block is threadedly connected to the threaded hole of the second connecting block. The rubber sealing ring of the mixing groove is tightly fitted to the outer wall of the bottom end of the top cover.

[0009] Preferably, a flow control valve is provided inside the discharge port.

[0010] Preferably, the mixing tank is equipped with baffles.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] 1. This utility model adopts a detachable top cover design for the mixing tank. When the stirring impeller is worn, stuck, or the impeller motor needs to be repaired, it is not necessary to disassemble the entire mixing tank structure. Only the top cover needs to be removed to replace or maintain the core components, which shortens the equipment downtime and reduces the loss of purification production interruption caused by maintenance.

[0013] 2. This utility model uses an impeller driven by an impeller motor to directly act on the materials in the mixing tank, which can quickly and evenly stir the phosphorus-containing polyvalent salt solution and the extractant, break down the liquid-liquid separation barrier, increase the contact area between the two phases, and improve the extraction reaction rate and completeness; it avoids the problem of incomplete extraction caused by uneven mixing, lays the foundation for subsequent purification processes, and ensures that the purity of the final product meets the standards.

[0014] 3. This utility model uses a linear drive mechanism to drive the mixing tank to rise and fall, replacing the traditional method of manually lifting or adjusting the tank. This avoids safety hazards such as tank tilting and material spillage that may occur during manual operation. The stability of the mechanical drive ensures that the mixing tank remains in a fixed position during the extraction process, preventing the stirring effect and extraction reaction stability from being affected by tank shaking, and reducing the interference of human operation errors on the purification effect.
