Detailed Description

Example 1

As shown in fig. 1, the liquid metal stirring device is made of high-temperature-resistant metal materials such as stainless steel, and comprises a flat annular pipe 1, an inclined straight pipe 3 with the bottom end welded with the annular pipe and the inside communicated with the annular pipe, a fixed support 4 arranged on the upper part of the straight pipe, an end cover 5 welded on the top end of the straight pipe and provided with a central hole, a thin tubular water nozzle 6 welded on the central hole of the end cover, and a circle of through holes 2 penetrating through the pipe wall are uniformly distributed on the annular pipe. The size and the shape of the annular pipe and the length of the straight pipe can be determined according to the size and the shape of a container for containing liquid metal, and the size and the number of the through holes on the annular pipe are determined according to the required stirring intensity. The fixing bracket 4 can be designed according to the actual situation of the use site, as long as the liquid metal stirring device can be firmly fixed by the fixing bracket. The fixing bracket of the embodiment comprises a cross frame 4a arranged on a straight pipe, a groove-shaped clamping frame 4b welded at two ends of the cross frame and provided with downward notches, and a fastening screw 4c assembled at one side of the groove-shaped clamping frame; the middle of the cross frame can be sleeved on the straight rod, and a support rod 4d can be additionally welded between the cross frame and the groove-shaped clamping frames at the two ends to improve the structural stability of the fixed support. The included angle between the planes of the inclined straight pipe and the annular pipe is 105-115 degrees, so that when the fixing support is fixed on the side wall of the metal liquid container, the annular pipe is basically located at the bottom of the center of the container.

As shown in fig. 3, the application method of the liquid metal stirring device of the present invention is as follows: the stirring device is inserted into a container 8 containing liquid metal 9, the stirring device is inserted until the annular pipe 1 is attached to a container bottom plate 8a, a groove-shaped clamping frame 4b of the fixed support 4 is clamped on the side wall of an upper opening of the container, a fastening screw 4c is screwed, the stirring device is fixed on the container, then a water nozzle 6 is connected with a water hose 7, the other end of the water hose is connected with a water tap, water is slowly injected into the stirring device through the water hose after the water tap is opened, the water flows downwards along the water nozzle and the straight pipe, the water is rapidly gasified into steam by high-temperature heating of the straight pipe and the annular pipe in the flowing process, the steam is discharged into the liquid metal through a through hole 2 on the annular pipe to form bubbles 10, and the bubbles continuously rise from the bottom of the container in the liquid metal to stir the liquid metal. When the water faucet is opened, the water quantity is controlled from small to large, the flow of the injected water is adjusted according to the stirring intensity of the liquid metal churning to form the required steam quantity until the formed bubbles reach the required churning stirring intensity in the metal liquid. The thin tubular water nozzle can ensure that the injected water quantity is less and controllable, and the condition of explosion caused by instant accumulation of water vapor can not be caused, thereby ensuring the production safety. The through hole 2 is arranged on the inner side wall, the outer side wall or the top of the annular pipe 1, and is not arranged at the bottom of the annular pipe as much as possible, so that the water entering from the water nozzle is prevented from vaporizing and not flowing into the molten metal completely.

Example 2

As shown in figure 2, the liquid metal stirring device is made of high-temperature-resistant metal materials such as stainless steel and comprises a straight pipe 3 which is obliquely arranged, a fixing support 4 which is arranged at the upper part of the straight pipe, an end cover 5 which is welded at the top end of the straight pipe and is provided with a central hole, and a thin tubular water nozzle 6 which is welded on the central hole of the end cover. In the embodiment, the annular pipe is not arranged, so that the lower end of the straight pipe is not closed or a straight pipe through hole 3a is formed in the lower pipe wall of the straight pipe. The stirring device of the present embodiment may be selected if the container used to contain the liquid metal on site is small or has low requirements for tumble stirring intensity. During the use, insert the straight tube to one side in the container of splendid attire molten metal, the straight tube bottom inserts the container bottom, then connect the hose on the water injection well choke, the other end water receiving tap of hose, open in the tap back water slowly pours into the straight tube into through the hose, water flows down along water injection well choke, straight tube, the control water yield, make water in the straight tube along the pipe wall flow in-process, before not reaching straight tube bottom or straight tube through-hole position complete gasification becomes vapor promptly, vapor discharges into liquid metal, form the bubble and constantly rise, stir liquid metal.

The stirring device of the utility model is particularly suitable for the stirring and boiling of liquid metal with the melting point higher than 100 ℃ such as tin liquid and the like.
