Ash poking hook for aluminium trichloride synthesizing sublimation pipe

Abstract

The invention discloses an ash poking hook for an aluminium trichloride synthesizing sublimation pipe, and belongs to the technical field of aluminium trichloride synthesizing equipment. The ash poking hook consists of a handle, a long iron pole, a ceramic disc plate, holes, a crew cap and a short iron pole, and is characterized in that: the vertical short iron pole on a balancing pole on the lower part of the long iron pole with the handle is connected with the ceramic disc plate provided with eight holes and a central round hole; the diameter of the ceramic disc plate is 20 centimeters, and the diameter of the holes on the ceramic disc plate is 1.5 centimeters; a screw on the short iron pole is sleeved in the central round hole of the ceramic disc plate, and is fixed with the screw cap through a gasket; in the using process, the handle is held by hands, and vertically downwards enters molten aluminium liquid in a synthesizing chlorination furnace, the ceramic disc plate enters the sublimation pipe through the lower port of the sublimation pipe, and the handle moves up and down and left and right to scrape and poke ash, so the ash on the wall of the sublimation pipe falls into the aluminium liquid and is fished out, and the synthetic reaction is smoothly carried out. The ash poking hook has the advantages of simple design, low cost, stable and continuous production, and environmental protection.

Description

Technical field [0001] The invention relates to an anhydrous aluminum chloride synthetic sublimation tube ash poking hook, in particular to an anhydrous aluminum chloride synthetic sublimation tube ash poking hook with a vertical ceramic disc, which belongs to the technical field of anhydrous aluminum chloride synthesis equipment. Background technique [0002] At present, the anhydrous aluminum chloride synthetic sublimation tube of the known technology will cause the aluminum slag in the molten aluminum to accumulate around the inner wall of the sublimation tube during the production process, and the ash must be poked once a day. The ash hook of the prior art All of them are made of iron, and there is a possibility that after the iron plate contacts the high-temperature molten aluminum at 750 degrees, part of the rust will fall into the molten aluminum, so that iron will be brought into the synthesis of anhydrous aluminum chloride, thereby producing ferric chloride , causin...

Problems solved by technology

[0002] At present, the anhydrous aluminum chloride synthetic sublimation tube of the known technology will cause the aluminum slag in the molten aluminum to accumulate around the inner wall of the sublimation tube during the production process, and the ash must be poked once a day. The ash hook of the prior art All of them are made of iron, and there is a possibility that after the iron plate contacts the high-temperature molten aluminum at 750 degrees, part of the rust will fall into the molten aluminum, so that iron will be brought into the synthesis of anhydrous aluminum chloride, thereby producing ferric chloride , causing the color of anhydrous aluminum chloride to turn yellow, or even black, so that secondary products or waste products are produced. At the same time, the ash hook of the prior art has a square contact geometric surface, and it will collide with a circular one during operation. The sublimation tube causes damage to the inner wall of the sublimation tube, which reduces the service life of the sublimation tube. Before the invention was made, there was no ceramic disc vertical anhydrous aluminum chloride synthetic sublimation tube to poke the ash hook. Search patent documents, no technical solution public
