The invention discloses a closed calcium carbide furnace calcium carbide liquid continuous discharging and high-temperature granulating device which comprises a continuous discharging unit, a granulating unit and a collecting tank which are sequentially arranged from top to bottom, the continuous discharging unit comprises a closed liquid storage bin and a siphon elbow, one end of the siphon elbow is communicated with the bottom of the liquid storage bin, and the other end of the siphon elbow is communicated with the collecting tank. The other end of the siphon elbow is a first discharge hole; the granulation unit comprises a barrel and a calcium carbide sieve, the bottom surface of the barrel is open, the top of the barrel is communicated with a first discharge port, the height of the first discharge port is adjustable, and the siphon elbow discharges calcium carbide liquid in the liquid storage bin from the first discharge port by utilizing a siphon effect; the calcium carbide sieve divides the cylinder body into two areas, namely a liquid containing area and a forming area; the calcium carbide screen is used for enabling calcium carbide liquid to fall into the forming area in a liquid drop mode, and the calcium carbide liquid is cooled into calcium carbide particles in the forming area and enters the collecting tank. The discharging speed is gradually reduced through natural reduction of the liquid level difference, and the problems of high-temperature abrasion, insufficient regulation and control precision and the like of an active flow control device are expected to be avoided.

The utility model discloses an antibacterial anti-oxidation eye cream packaging bottle which comprises a bottle body and a bottle cap. An inner container is mounted in the bottle body, an antibacterial layer is arranged on the inner surface of the inner container, and an anti-oxidation layer is arranged on the outer surface of the inner container; an annular sealing edge extending downwards is arranged on the edge of the top of the inner container, an annular groove is formed between the annular sealing edge and the outer side wall of the inner container, and buckles fixedly connected with the outer side wall of the inner container are fixedly connected to the two sides of the interior of the annular groove respectively. The top of the bottle body is fixedly connected with an annular protrusion connected with the annular groove in a matched and inserted mode. The two sides of the annular protrusion are provided with clamping grooves connected with the buckles in a matched mode respectively. The inner container is installed in the bottle body, the antibacterial layer is arranged on the inner surface of the inner container, and the anti-oxidation layer is arranged on the outer surface of the inner container, so that eye cream can be effectively prevented from being polluted by bacteria, meanwhile, the anti-oxidation capacity of the inner container is prolonged, and the service life of the inner container is prolonged.
