Abstract
The utility model relates to an industrial quartz glass crucible with a cover. The industrial quartz glass crucible consists of a crucible body and a crucible cover, wherein the crucible cover is arranged on the crucible body and divided into two types, namely a perforated cover and a closed cover which respectively form a perforated type quartz glass crucible and a closed type quartz glass crucible together with the crucible body, and the perforated type quartz glass crucible and the closed type quartz glass crucible are respectively used in two different situations that materials to be processed in the quartz glass crucibles produce gas and do not produce gas when the objects are heated at high temperature. The industrial quartz glass crucible with the cover has the advantages of preventing falling objects from falling into materials in the open crucible in use to ensure high purity and high quality of the materials to be processed; and the perforated cover has different forms of opening or open hole design, thus having the dust prevention and exhaust effects.

Above-mentioned silica crucible all is uncovered vessel, has the thing that sinks to fall in the material in the silica crucible in use unavoidably, causes the purity of material to descend.For example; Technical grade zirconium dioxide or high-purity zirconium dioxide that current employing hydrometallurgy is made; Its purity requirement is 99.5% to 99.999%; Its product technology is to put into uncovered silica crucible to zirconium oxychloride, slowly moves calcination in the normal pressure about 1000 degree Celsius that are built into refractory brick, the hyperthermia tunnel Kiln and processes.Have hydrogen chloride gas to produce in this process, the tunnel cave furnace roof has the thing that sinks and falls in the product during hydrogen chloride gas volatilization, causes the product purity quality to descend.
Summary of the invention:
The utility model technical problem to be solved provides a kind of relevant industries that can prevent to use silica crucible and is producing the quartz glass crucibles industrial with cover that has the thing that sinks to cause the product purity quality to descend in the processed material in falling into when using.
In order to solve the problems of the technologies described above; The utility model is realized through following technical scheme: a kind of industrial quartz glass crucibles with cover; Has the crucible body; Said crucible body is provided with crucible cover, and said crucible cover is divided into loose gas lid and two kinds of closing caps, and respectively with said crucible body composition air-leakaging type quartz glass crucibles and closed quartz glass crucibles.
The displacement slippage of crucible cover in order to prevent to use, further, the mating interface of said crucible cover and crucible body is respectively outer tiltedly miter angle and interior oblique miter angle.
In order to play loose gas or the attacker's effect when uncapping, further, said air-leakaging type quartz glass crucibles crucible cover is provided with air diffuser.
In order to play the gas effect of loosing, further, said air-leakaging type quartz glass crucibles crucible body is provided with air dispelling hole.
Picking and placeing of crucible cover for ease, further, said closed quartz glass crucibles crucible cover top is provided with handgrip.
In order to solve the closed quartz glass crucibles problem that gas expands in the crucible under the high temperature air-tight state uses, further, said closed quartz glass crucibles crucible body has an air leakage hole near the position of crucible mouth.
In order to improve the diffusing gas efficient of air-leakaging type quartz glass crucibles, more further, said air diffuser is circular, trapezoidal, triangle or rectangle.
In order to guarantee the durability of closed quartz glass crucibles handgrip, further, the diameter of said handgrip is the 10-60 millimeter, and length is the 10-100 millimeter.
Compared with prior art, the usefulness of the utility model is: this industrial quartz glass crucibles with cover thing that can prevent to sink is in use gone in the material of open pot, can make the machined object high-purity, high-quality; And this industrial quartz glass crucibles with cover has diffusing gas lid and two kinds of multi-form lids of closing cap; Diffusing gas is stamped multi-form opening or perforate design, plays the effect of not only dustproof but also diffusing gas.
