Embodiment Construction

[0012] from figure 1 , figure 2 , image 3 , Figure 4 , Figure 5 It can be seen that the present invention is from top to bottom from the top suspension ring 1, the cylindrical joint body 2, the sealing nut 3, the locking nut 4, the tubular upper gun body 5, the connecting nut 6, the tubular lower gun body 7, the connecting bend Tube 8 is composed. The suspension ring 1 is connected together with the upper part of the joint body 2 by bolts. The upper gun body 5 includes an upper spray gun tube 15. The upper and lower surfaces of the upper spray gun tube 15 are all provided with threads, and the top of the upper thread is screwed into the bottom of the joint body 2. At the same time, the upper thread is equipped with a sealing nut 3 and a locking nut 4, and a sealing gasket 9 is placed between the sealing nut 3 and the bottom of the joint body 2 to play a sealing role and prevent leakage. The outer surface of the upper spray gun tube 15 is covered with a long section of...

Abstract

The invention discloses a magnesium oxide spray gun. The magnesium oxide spray gun is characterized in that the lower end of a connecting elbow is welded at the upper end of a connector body; a hanging ring is connected with the upper part of the connector body through a bolt; an upper gun body comprises an upper spray gun tube; threads are arranged on the outer surfaces of the upper part and the lower part of the upper spray gun tube; the top of the upper thread is screwed into the lower part of the connector body; a sealing nut and a locking nut are mounted on the upper thread in a sleeving manner; a long sealing outer sleeve sleeves the outer surface of the middle part of the upper spray gun tube; the sealing outer sleeve and the upper spray gun tube are fixed through a connecting reinforcing plate; the lower thread of the upper spray gun tube is a left-hand thread, and is screwed into the upper end of a connecting nut; the upper end of the connecting nut is a left-hand thread; the lower end of the connecting nut is a right-hand thread; a lower gun body comprises a lower spray gun tube; the upper end of the lower spray gun tube is screwed into the lower end of the connecting nut; thorn plates are arranged on the outer surface of the lower spray gun tube; and the thorn plates are uniformly smeared with a circle of fire resistant material. According to the magnesium oxide spray gun, the working efficiency of magnesium making can be improved, and the vacuum environment of a vacuum melting furnace is not damaged during continuous operating.

Description

technical field [0001] The invention relates to a magnesium smelting industry, in particular to a magnesium oxide spray gun equipment used for spraying magnesium oxide powder to a vacuum melting furnace at high speed. Background technique [0002] In the magnesium smelting industry, there are many ways to extract magnesium. For example, under high temperature and vacuum conditions, in the presence of calcium oxide, magnesium vapor is generated by reducing magnesium oxide with silicon, which interacts with the solid dicalcium silicate (2CaO SiO2) produced by the reaction. Separated and condensed to obtain crystalline magnesium. The high temperature and vacuum condition is to use the vacuum melting furnace to spray high-speed magnesium oxide powder into the melting pool in the melting furnace, which requires a magnesium oxide spray gun equipment. The purpose of the magnesia spray gun equipment is to spray magnesia powder to the vacuum melting furnace. Its working principle is...
