Description

Technical Field

[0001] This utility model relates to the field of potassium perchlorate washing and extraction, and in particular to a potassium perchlorate washing and extraction device. Background Technology

[0002] The produced sodium perchlorate contains impurities such as KCl and NaCl that need to be removed. The solubility of sodium perchlorate is 0.75 at 0 degrees Celsius and 22.2 at 100 degrees Celsius. The solubility of impurities KCl and NaCl changes little with temperature (e.g., the solubility of KCl is 34g at 20 degrees Celsius). Therefore, potassium perchlorate can be purified by a process of "high-temperature dissolution → hot filtration to remove insoluble impurities → low-temperature cooling crystallization → filtration and washing to remove soluble impurities". Based on this principle, we designed a potassium perchlorate washing and extraction device. Summary of the Invention

[0003] The purpose of this utility model is to overcome the shortcomings of the existing technology, adapt to practical needs, and provide a potassium perchlorate washing and extraction device, including a washing tank and a cooling precipitation tank; a stirring rod is provided inside the washing tank, and the stirring rod is connected to a stirring motor above the washing tank; a water inlet and a feed inlet are provided above the washing tank; a liquid outlet is provided at the bottom of the washing tank; a liquid outlet valve is provided at the liquid outlet; a liquid outlet bend is connected below the liquid outlet valve; the liquid outlet of the liquid outlet bend extends into the cooling precipitation tank; a precipitation roller is provided inside the cooling precipitation tank; a cooling device is provided inside the precipitation roller; the precipitation roller is driven by a rotating motor; a scraper 12 is provided on one side of the precipitation roller; and a discharge trough is inclinedly provided below the scraper.

[0004] A thermometer is installed above the washing tank.

[0005] A metal cooling water pipe is spirally arranged inside the precipitation drum. The two inlets and outlets of the metal cooling water pipe pass through the rotating shafts on both sides of the precipitation drum and are connected to the cooling water pipe through a rotary joint.

[0006] The washing tank is equipped with an inner coil, and the steam inlet and steam outlet of the inner coil are located on the outside of the washing tank.

[0007] A feeding hopper is provided above the feeding port, and a feeding screw is provided at the connection between the feeding hopper and the feeding port. The feeding screw is connected to a feeding motor.

[0008] The beneficial effects of this utility model are as follows: By continuously feeding clean water and materials containing impurities, and through heating and stirring to achieve continuous mixing, the mixture is then sent through water pipes to a cooling and precipitation tank to continuously precipitate the materials, thereby achieving a purification effect.
