Technical Field

The invention relates to an impurity removal tool, in particular to a ventilation purification impurity removal tool for a cast aluminum alloy solution.

Background

During a casting aluminum alloy melting alloying test, purification and impurity removal are very critical procedures, and the macroscopic and microscopic mechanical properties of the aluminum alloy are directly influenced by the quality of the purification and impurity removal effect. The purification and impurity removal mainly comprises two modes of adding a reagent to remove impurities and introducing purified gas to remove impurities. The invention relates to a ventilation tool designed and manufactured aiming at ventilation tools needed in ventilation purification and impurity removal, and mainly relates to a ventilation purification and impurity removal tool for casting aluminum alloy solution in a laboratory.

Disclosure of Invention

The invention aims to provide a ventilation purification impurity removal tool for a cast aluminum alloy solution. The invention is suitable for ventilation purification and impurity removal of the aluminum alloy casting solution in the laboratory, and has the characteristics of convenient use, stable and reliable impurity removal, good effect and simple structure.

The technical scheme of the invention is as follows: the utility model provides a casting aluminum alloy solution purifies edulcoration instrument of ventilating, leads to the head including graphite, and graphite is led to the head and is connected with nonrust steel pipe, and the upper end of nonrust steel pipe is equipped with the fixed block, and the lower extreme of fixed block is equipped with tubaeform locating piece, is equipped with current stabilizer and control flap on the nonrust steel pipe of fixed block top in proper order, and control flap has the manometer through hose connection, and the manometer is connected with inert gas storage tank.

In the above described cast aluminum alloy solution aeration purification impurity removal tool, the graphite aeration head is of an ellipsoidal shape.

In the ventilation purification impurity removal tool for the cast aluminum alloy solution, the side with the large radius of the horn-shaped positioning block is arranged downwards.

In the ventilation purification impurity removal tool for the cast aluminum alloy solution, the connecting positions of the hose and the control valve or the pressure gauge are respectively provided with the anchor ear.

In the ventilation purification impurity removal tool for the cast aluminum alloy solution, the horn-shaped positioning block is located above the melting furnace.

In the above tool for purifying and removing impurities by ventilating the cast aluminum alloy solution, the lower end of the stainless steel tube and the graphite ventilating head are located in the crucible.

In the ventilation, purification and impurity removal tool for the cast aluminum alloy solution, a main valve is arranged on the inert gas storage tank.

Compared with the prior art, the invention has the following beneficial effects:

when the invention is used, when an experiment of casting aluminum alloy below 10 kg is carried out in a laboratory, after the aluminum alloy is melted and alloyed, the alloy solution needs to be transferred out of a smelting furnace for final casting and molding. When the cast aluminum alloy is melted and alloyed, a main valve and a control valve on an inert gas storage tank are opened, gas in the inert gas storage tank enters a graphite ventilation head through a pressure gauge, a hose, the control valve, a stainless steel pipe and a current stabilizer, the graphite ventilation head is ventilated, then the lower end of the stainless steel pipe and the graphite ventilation head are placed in a crucible, and the stainless steel pipe and the graphite ventilation head go deep into an aluminum alloy solution and move slowly; the horn-shaped positioning block is positioned above the smelting furnace, and the graphite ventilation head and the stainless steel tube are fixed on the smelting furnace and the crucible through the horn-shaped positioning block and the fixing block, so that the use is convenient; then, the ventilation size of the graphite ventilation head is controlled by a control valve, and meanwhile, under the action of a current stabilizer, the gas can be ensured to be stably output through the graphite ventilation head, so that the situations that the aluminum alloy solution is lost and even safety accidents are caused due to the fact that the output of inert gas is unstable and suddenly changes, so that the aluminum alloy solution in the crucible is subjected to bumping, splashing and the like are avoided; after the ventilation and purification are finished, firstly removing the aluminum alloy solution from the stainless steel pipe and the graphite ventilation head, continuously ventilating for 1-3min to remove the aluminum alloy solution adhered in the graphite ventilation head, preventing the aluminum alloy from blocking an air outlet on the graphite ventilation head after solidification, and then closing a main valve and a control valve on the inert gas storage tank, so that the inert gas storage tank is convenient to use next time and has a simple structure; the stainless steel tube is high temperature resistant, and the stainless steel tube does not pollute the aluminum alloy solution in the crucible when the stainless steel tube is ventilated, purified and decontaminated; observe the gas storage condition in the inert gas reservoir jar through the manometer, if the numerical value on the manometer is low excessively, in time change inert gas reservoir jar.

In conclusion, the invention has the beneficial effects of being suitable for ventilating, purifying and removing impurities of the aluminum alloy casting solution in the laboratory, convenient use, stable and reliable impurity removal, good effect and simple structure.
