The utility model discloses a hand splint for assisting pediatric nurses in injection, and relates to the technical field of pediatric medical instruments, the hand splint for assisting pediatric nurses in injection comprises a fixed shell, the surface of the fixed shell is fixedly connected with a rubber belt, the surface of the fixed shell is slidably connected with a sliding block, and the inside of the fixed shell is fixedly connected with a motor. The output end of the motor is fixedly connected with a rotating shaft, the surface of the rotating shaft is fixedly connected with a rotating disc, the surface of the rotating disc is provided with a limiting groove, and the inner wall of the limiting groove is slidably connected with a connecting rod. Furthermore, the convex block continuously moves up and down to massage the hand of the child, so that the hand is kept active, the situation that the hand of the child is stiff and numb due to the fact that the hand of the child is fixed for a long time is avoided, the comfort of the child during injection is improved, and the using effect of the device is improved.

The utility model relates to the technical field of mining engineering, disclose a kind of anti-blocking shunt type ball mill feeder applied to fluorite flotation, including feed pipe, the left end of the feed pipe is provided with ball mill, the top of the feed pipe is fixedly connected with support plate, the top of the support plate is fixedly connected with motor one, the output of motor one is fixedly connected with rotating rod, the inner wall of the feed pipe is fixedly connected with connecting rod, the outer wall of the connecting rod is penetrated and is slidably connected with screening net, the top of the screening net is provided with movable mechanism, in the utility model, after adding ore raw material, open double motor, rotating rod and extruding rod are driven by motor one, reciprocating vertical movement of screening net is made by cooperating extrusion groove, both screening fluorite raw material and keeping raw material active can be achieved, avoid accumulation and block, after screening, raw material can also be divided into multiple groups by distributor blade, and uniformly sent into ball mill grinding.

This invention relates to a water-cooled pipe for the bottom of a blast furnace, belonging to the field of metallurgical industry. The water-cooled pipe (2) is arranged at the bottom of the blast furnace, divided into an inner ring region, a middle ring region, and an outer ring region from the inside out according to the distance from the center of the blast furnace. The diameter of the water-cooled pipe (2) in the inner ring region is smaller than that in the middle ring region, which is smaller than that in the outer ring region. The cooling intensity gradually decreases from the outside to the inside, forming a pot-bottom erosion curve (1) inside the blast furnace hearth, thereby increasing the core temperature of the blast furnace hearth. This invention can enhance the cooling of the elephant foot region of the hearth, slow down the erosion of the refractory material in the elephant foot region, reduce the diameter of the middle ring pipe, reduce the cooling area, and minimize the diameter of the inner ring pipe, resulting in the smallest cooling area. The cooling intensity gradually decreases from the outside to the inside, thus forming a pot-bottom erosion, while simultaneously increasing the core temperature, ensuring the hearth is active, and extending the hearth's lifespan.
