Description

Technical Field

[0001] The invention relates to the technical field of zirconium sponge production, and in particular to a reduction control method for zirconium sponge production. Background Art

[0002] The process of producing zirconium sponge by magnesium method is to add zirconium tetrachloride into the reactor, reduce it with metallic magnesium, and obtain zirconium sponge after distillation and purification. The thermal reduction reaction of zirconium tetrachloride and magnesium is a strong exothermic reaction. If the reaction temperature is too high, the zirconium sponge will sinter due to the high temperature, so that the density of the zirconium sponge product in the center of the zirconium sponge lump is too high. Therefore, it is necessary to accurately and immediately control the temperature in the reactor.

[0003] The internal temperature monitoring and control of the reactor used in the existing magnesium method for producing zirconium sponge is mainly completed by real-time monitoring through temperature sensors. However, due to the fixed position of the temperature sensor, it can only monitor the temperature of a fixed area and cannot accurately measure the temperature of each part of the reactor, resulting in the inability to accurately obtain the temperature distribution and changes in the reactor.

[0004] Therefore, in view of this, the existing structure and defects are studied and improved, and a reduction control method for sponge zirconium production is proposed. Summary of the invention

While the liquid magnesium reacts with the zirconium tetrachloride, temperature measuring elements of different heights are used to realize instant temperature feedback of the liquid magnesium and the space above it at different heights; Step 2: The driving motor drives the driving gear so that the transmission gear carries the reciprocating screw and the oil cylinder to rotate at a uniform speed, so that the movable sleeve seat moves back and forth along the surface of the reciprocating screw rod. When the movable sleeve seat descends, the transmission pressure rod is pushed to be pressed into the inside of the oil cylinder, so that the oil inside the oil cylinder is pressed into the inside of the bellows sleeve, so that the bellows sleeve stretches to push the sliding seat to slide along the outer wall of the limiting sliding rod, so that the temperature measuring elements at various heights can be away from the oil cylinder, and at this time, the temperature measuring elements rotate at a uniform speed with the oil cylinder, so as to provide instant temperature feedback for various positions inside the reactor; Step 3: When the movable sleeve rises, the transmission pressure rod naturally resets and rises. At this time, the oil re-enters the oil cylinder, causing the temperature measuring element to slide back and reset close to the oil cylinder, and enter the next cycle as the movable sleeve descends.

[0007] Furthermore, the reduction control method for sponge zirconium production uses a reaction device, which includes a reactor, a large cover is provided on the top of the reactor, and a sleeve is provided in the middle of the surface of the large cover.

[0008] Furthermore, a feeding pipe is arranged in parallel on one side of the cylinder sleeve, and a sealing gasket is arranged inside the cylinder sleeve, and a temperature measuring component is penetrated inside the sealing gasket.
