[0019] The crystallization box 1 is composed of two upper and lower arc-shaped boxes, and the distance between the inner wall of the upper arc-shaped box of the crystallization box 1 and the rotating cylinder 3 is smaller than the distance between the inner wall of the lower arc-shaped box of the crystallization box 1 and the rotating cylinder 3; a liquid inlet valve port 101 is arranged on the upper side of the front end surface of the crystallization box 1, and a liquid outlet valve port 102 is arranged on the lower side of the front end surface of the crystallization box 1, and a cooling pipe 103 is fixed on the lower end surface of the crystallization box 1, and a water inlet and a water outlet are arranged on the cooling pipe 103; a fixing frame 104 is also fixed on the front end surface of the crystallization box 1, and a motor 2 is fixed on the fixing frame 104, and the output end of the motor 2 is fixed to the rotating cylinder 3; When using the liquid cooling crystallization device for preparing barium chloride using waste barium slag, Figure 1-Figure 5As shown, firstly, the circulation pump is connected to the water inlet on the cooling pipe 103 and the cooling water tank through a conduit, and then the water outlet on the cooling pipe 103 is connected to the cooling water tank through a conduit, so as to realize the recycling of cooling water. Then, the barium chloride solution is injected into the crystallization box 1 through the liquid inlet valve port 101, and the liquid level of the barium chloride solution is lower than the lower end surface position of the rotating cylinder 3. At this time, the cooling water circulating in the cooling pipe 103 can cool the crystallization box 1 and the barium chloride solution in the crystallization box 1, so that the barium chloride crystals are precipitated. At this time, the rotating cylinder 3 is driven by the motor 2 to rotate slowly, thereby driving the fixed plate 401 and the screen 402 to rotate slowly. Through the rotation of the fixed plate 401 and the screen 402, the turbulence of the barium chloride solution can be realized, so as to ensure the balance of the liquid temperature, and when the liquid temperature is lowered, the chlorine When barium chloride crystals are precipitated, the barium chloride crystals and the barium chloride liquid can be separated by rotating the screen 402. When the screen 402 rotates from bottom to top, due to the special-shaped structure of the crystallization box 1, the screen 402 is forced to slide into the fixed plate 401, thereby driving the connecting rod 404 and the scraper 405 to move, and the sliding action between the screen 402 and the fixed plate 401 makes the separated barium chloride crystals on the screen 402 fall off, and the sliding action between the scraper 405 and the fixed plate 401 makes the barium chloride crystals on the bonded fixed plate 401 fall off. When the screen 402 reaches the upper part of the crystallization box 1, under the action of gravity, the barium chloride crystals and the residual barium chloride liquid automatically fall down, and fall onto the material guide mechanism 5 through the strip groove 301, thereby realizing the automatic collection of the barium chloride crystals; The material guide mechanism 5 is composed of a mounting frame 501, a material guide plate 502 and an arc block 503. The mounting frame 501 is fixed on the crystallization box 1, and the mounting frame 501 is in contact with the rotating cylinder 3, and the material guide plate 502 is rotatably connected to the mounting frame 501; the rear end surface of the material guide plate 502 is arranged above the collecting mechanism 6, and the arc block 503 is fixed on the lower end surface of the material guide plate 502; the collecting mechanism 6 includes a collecting box 601, a baffle 602, a filter screen 603, a reflux pipe 604, a vertical rod 605, a slide rod 606, a convex shaft 607, a gear 608, a slide rod 609, a mounting plate 610 and a second spring 611, the collecting box 601 is arranged below the material guide plate 502, and the baffle 602 is fixed on the collecting box 601, and the baffle 602 is arranged on the rear side of the material guide plate 502, and the inside of the collecting box 601 A filter screen 603 is fixed, and a return pipe 604 is fixed on the collection box 601, and the return pipe 604 is arranged in the rotating cylinder 3; a vertical rod 605 is fixed on the collection box 601, and the vertical rod 605 is slidably connected to the arc block 503; a slide rod 606 is fixed to the lower end of the collection box 601, and the slide rod 606 is slidably connected to the convex shaft 607, and the convex shaft 607 is fixed to the gear 608, and the gear 608 bearing is connected to the crystallization box 1, and the gear 608 is meshed with the convex tooth block 302; sliding rods 609 are symmetrically fixed on the collection box 601, and the sliding rods 609 are slidably connected to the mounting plate 610, and the mounting plate 610 is fixed to the crystallization box 1, and a second spring 611 is fixed between the mounting plate 610 and the sliding rod 609; When the barium chloride crystals and the remaining barium chloride liquid fall automatically, Figure 1-Figure 7As shown, at this time, the falling barium chloride crystals and residual barium chloride liquid fall onto the guide plate 502, and when the rotating cylinder 3 rotates, the convex tooth block 302 is synchronously driven to rotate, and the meshing transmission action between the convex tooth block 302 and the gear 608 is coordinated to make the convex shaft 607 rotate, and the sliding action between the convex shaft 607 and the slide slot rod 606 is coordinated to make the collection box 601 move left and right in an orderly manner, and the sliding guide action between the slide bar 609 and the mounting plate 610 is coordinated to ensure the stability of the movement of the collection box 601. When the collection box 601 moves, the vertical rod 605 is synchronously driven to move. When the vertical rod 605 is separated from the arc block 503, under the action of gravity, the rotation action between the guide plate 502 and the mounting frame 501 makes the rear side of the guide plate 502 tilt downward, so that the barium chloride crystals and residual barium chloride liquid on the guide plate 502 are The remaining barium chloride liquid automatically slides into the collection box 601 and is collected. When the vertical rod 605 contacts and slides with the arc block 503, the guide plate 502 is reset to a horizontal state.

The barium chloride crystals and the remaining barium chloride liquid entering the collection box 601 can be separated from the solid by the filter screen 603 again. In conjunction with the left and right reciprocating motion of the collection box 601, the barium chloride crystals on the filter screen 603 move synchronously, which can better shake off the liquid on the barium chloride crystals. The separated liquid automatically flows back to the crystallization box 1 through the reflux pipe 604 and the strip groove 301 on the rotating cylinder 3 so as to be cooled and crystallized again. This is the working principle of the liquid cooling and crystallization device for preparing barium chloride using waste barium slag.
