Technical field

The present invention relates to yellow phosphorus bell technical field, especially a kind of Yellow phosphorus furnace furnace cover structure and preparation method thereof and the stove The insulation material used in lid structure.

Background technology

Yellow phosphorus is called white phosphorus as white to light yellow crisp waxy solid, 44.1 DEG C of fusing point, 280 DEG C of boiling point, and 1.82 grams of density/ cm³, very vivaciously, it is necessary to be stored in water, people sucks 0.1 gram of white phosphorus and will be poisoned to death, and has stronger corrosivity. Therefore, the production process for yellow phosphorus is that yellow phosphorus raw material is placed in closed container to produce in the prior art, its is main Carried out in Yellow phosphorus furnace；Also this is based on, it is unreasonable for the structure setting of the bell of Yellow phosphorus furnace, not only result in yellow phosphorus In operation, there is potential safety hazard in the worker of production, and the cost for also resulting in phosphorus production is higher, and equipment uses the longevity Order relatively low.

Most of yellow phosphorus bell of the prior art is prepared using stainless steel material so that yellow phosphorus bell into This is higher, and the weight of stainless steel bell is larger, the operation being unfavorable for during phosphorus production, and safety coefficient is relatively low.

In consideration of it, this researcher combines long-term practice and exploring, the structure of yellow phosphorus bell is improved and handled, and The selection of the raw material, especially insulation material of preparation technology and use to yellow phosphorus bell, it is yellow phosphorus furnace cover structure preparation field Provide a kind of new approaches.

The content of the invention

In order to solve above-mentioned technical problem present in prior art, the present invention provide a kind of Yellow phosphorus furnace furnace cover structure and its The insulation material used in preparation method and the furnace cover structure.

It is achieved particular by following technical scheme：

A kind of Yellow phosphorus furnace furnace cover structure, is made up of top plate and lower plywood, girth sheets, and wherein top plate passes through circle with lower plywood Plate is connected, and the casing of circle is formed between top plate and lower plywood；Electrode hole, charging aperture are provided with top plate, electricity Pole hole and charging aperture are disposed alternately on top plate, and inspection hole and gas port are additionally provided with top plate, inspection hole with The position of gas port is positioned opposite；And electrode hole, charging are also equipped with the position corresponding with top plate on lower plywood Hole, inspection hole and gas port；And electrode hole, charging aperture, inspection hole, the gas port on top plate are corresponding with lower plywood Electrode hole, charging aperture, inspection hole, gas port are connected by first partition with second partition, between first partition and second partition Interlayer is formed, and heat-insulation layer is set between interlayer；First partition stretches out lower plywood, and top is connected with top plate；Second every The top of plate is connected with top plate, and bottom is connected with lower plywood；Described circular box house is provided with inner reinforced plate；Described Girth sheets, its one end are connected with the lower plane edge of top plate, and other end exceeds the distance between top plate and lower plywood, and And lower plywood is connected on girth sheets；Described first partition stretches out lower plywood, its length stretched out and girth sheets beyond top plate and The equal length of the distance between lower plywood one end, and guarantor is provided with the groove that lower plywood, girth sheets, first partition are formed Warm layer；It is provided with electrode hole on the upper surface of top plate every magnetic economize on electricity part, and every magnetic economize on electricity part and electrode hole To be concentric, perpendicular to the upper surface of top plate.

Described lower plywood, it is provided with its lower surface and pours muscle.
