The invention provides a mechanical stirring cooling-type
crystallization device. The mechanical stirring cooling-type
crystallization device comprises an upper cover body, a cover body seat, a coverbody support, an
argon receiving opening, a fixed button, a slide groove, a main rotating shaft, a slide groove, a locking block, a transmission bolt hole, a transmission motor, a motor plate, a fixedhole, a motor sealing groove and a
transmission belt; the top of the periphery of the upper cover body is provided with an annular groove; one side of the fixed button is provided with the slide groove, one side of the fixed button is provided with a square hole, and a
locking plate is movably arranged in the slide groove by virtue of the square hole; and one side of the fixed button is providedwith a propelling bolt hole, a lower cover body adopts a bolt to penetrate through the propelling bolt hole to lock the
locking plate, so as to be fixed on the bottom of the upper cover body, the inner side top of the upper cover body is provided with the
argon receiving opening and an
airflow baffle plate, the mechanical stirring cooling-type
crystallization device can be connected with
argon soas to inject argon, a
crystal can be crystallized in a
pollution-free manner by utilizing the chemical characteristic that argon does not react with other elements, and the direct flow direction of argon is limited, so that argon is prevented from directly blowing the
crystal and from causing the
cracking of the
crystal.
