The utility model discloses a movable crystallization kettle for chemical industry, which comprises a transmission box. The bottom of the transmission box is fixedly connected with two relatively symmetrical supporting legs. The middle part of the inner top wall of the transmission box is fixed with a first bearing, the middle part of the inner bottom wall of the transmission box is fixed with a second bearing, and the inner part of the transmission box is arranged with a cylinder, and the upper part of the outer surface of the cylinder and the inner part of the first bearing. The ring is fixedly connected, and the lower part of the outer surface of the cylinder is fixedly connected with the inner ring of the second bearing. The easy-to-move crystallization kettle for chemical industry canmake the second column drive the roller to contact with the ground by setting rollers, under the action of positive and negative motor, cylinder, screw, nut and transmission rod. The problem of inconvenient movement of traditional crystallization kettle can be solved. The purpose of facilitating the movement of the kettle body can be achieved by the device. The kettle capital can be made by setting support legs. When the body moves to an appropriate position, the supporting leg contacts the ground, which makes the device more stable.
