This can ensure that the water flow evenly covers every corner inside the crystallization kettle body 1, and realizes flushing without dead ends. The high-pressure water flow can effectively flush away the crystallization residues attached to the inner wall of the crystallization kettle body 1, thereby improving the cleaning efficiency. The automated flushing system can reduce the need for manual cleaning, save labor costs, and reduce the labor intensity of operators. The efficient flushing system can significantly shorten the cleaning cycle, speed up the production process, and improve equipment utilization. Regular use of the flushing nozzle 14 for cleaning can prevent crystals from accumulating and clogging inside the crystallization kettle body 1, thereby extending the service life of the equipment.

[0031] Specifically, a lower hopper 8 is fixedly installed at the bottom of the crystallization kettle body 1, a lower material port 12 is provided in the inner cavity of the lower hopper 8, a discharge pipe 9 is fixedly installed at the bottom of the lower hopper 8, and a support bottom plate 2 is fixedly sleeved on the surface of the crystallization kettle body 1 near the bottom.

[0032] Furthermore, the crystallized material is discharged through the discharge hopper 8, and the discharge pipe 9 controls the discharge amount and the switch through the electromagnetic valve.

[0033] Specifically, the hair blowing mechanism 3 is fixedly installed on the right side of the bottom of the supporting base plate 2. The hair blowing mechanism 3 includes a hair blowing fan 301, a hair blowing duct 302, a casing 303 and fan blades 304.

[0034] Furthermore, the blowing mechanism 3 can perform a blowing operation through the blowing fan 301 and the fan blades 304, and blow the generated wind force toward the inside of the crystallization kettle body 1. The angle is aligned upward through the rotatable blowing duct 302, and the wind force is blown into the inside of the crystallization kettle body 1, so that the crystals stuck inside the crystallization kettle body 1 can be blown off, making it convenient to clean.

[0035] Specifically, a pressure valve 5 is provided on the left side of the top of the top cover 6 , and a feed pipe 11 is fixedly installed on the right side of the top of the top cover 6 .

[0036] Furthermore, the pressure valve 5 performs pressure relief processing when the pressure inside the crystallization kettle body 1 is too high, and the feed pipe 11 facilitates the feeding of the sodium tungstate solution into the crystallization kettle body 1.

[0037] Specifically, a water pumping pipe 10 is fixedly installed on the right side of the top cover 6, and one end of the water pumping pipe 10 is fixedly connected to the flushing nozzle 14 through an annular water supply pipe, and the two are interconnected.

[0038] Furthermore, the water pumping pipe 10 can be used to transport water to the flushing nozzles 14 , and the annular water supply pipe can ensure that water is supplied to each flushing nozzle 14 .

[0041] Working principle: the feed pipe 11 is convenient for feeding the sodium tungstate solution into the crystallization kettle body 1. During the crystallization process, raw materials such as tungstic acid or ammonium tungstate are dissolved in water to form a sodium tungstate solution. The supersaturation of the solution is controlled by heating or cooling to promote the precipitation of sodium tungstate crystals from the solution. The blowing mechanism 3 can blow air through the blowing fan 301 and the fan blades 304, and the generated wind force is blown into the crystallization kettle body 1. The rotatable blowing pipe 302 is used to aim upwards to blow the wind force into the crystallization kettle body 1, thereby The crystals stuck inside the crystallization kettle body 1 can be blown off, which is convenient for cleaning. The discharge amount and switch of the discharge pipe 9 are controlled by the solenoid valve. After the crystals are discharged from the crystallization kettle body 1, water is flushed into the flushing nozzle 14 through the pumping pipe 10. The flushing nozzle 14 can fully flush the inside of the crystallization kettle body 1, and spray water at different angles and directions to ensure that the water flow evenly covers every corner inside the crystallization kettle body 1, realizing flushing without dead ends. The pressure valve 5 performs pressure relief treatment when the internal pressure of the crystallization kettle body 1 is too high.

The stirring and cleaning mechanism 4 can help disperse and mix the cleaning liquid or water flow, so that the cleaning agent can be more evenly distributed throughout the crystallization kettle body 1, thereby improving the cleaning efficiency. The flow force generated by the stirring can enhance the flushing effect of the cleaning liquid on the inner wall of the crystallization kettle body 1, which helps to remove stubborn crystal residues and dirt, and ensure that the cleaning liquid reaches every corner inside the crystallization kettle body 1, including hard-to-reach areas, reducing or eliminating cleaning dead corners.
