Embodiment

[0067] The present embodiment uses the system for producing calcium carbide liquid provided by the invention to produce calcium carbide liquid, and the specific method is as follows:

[0068] Put the carbon powder and quicklime powder from the toner bin and quicklime bin into the carbon powder weighing device and the quicklime powder weighing device for weighing, and put the weighed carbon powder 200Kg and quicklime powder 300Kg into the mixer respectively mix in. After mixing evenly, put it into the hopper below it, then lift the hopper filled with the mixture to the top of the mixing silo through the hopper elevator, add the mixture into the mixing silo, and put the mixture into the mixing weighing device middle. Put the feeding pipe from the waiting position of the feeding pipe to the feeding position of the feeding pipe, and add 200Kg of the weighed mixture into the induction furnace. After adding the material, cover the furnace cover, and put the dust removal hood from ...

Abstract

The invention relates to an induction furnace, a system for production of calcium carbide liquid with the induction furnace and a method. The induction furnace consists of a crucible, a quartz sand layer, a furnace shell and a furnace cover, the crucible top is provided with an opening, and a discharge port is disposed at the upper part of the side wall. The quartz sand layer is a shell with an open top, and the crucible is located in the inner cavity of the furnace shell. The furnace cover is located above the crucible top opening. An asbestos board is disposed outside the side wall of the quartz sand layer, the outside of the asbestos board is surrounded by an induction coil, and the outside of the coil is equipped with a water-cooled pipe. A casting body is fixed between the bottom of the quartz sand layer and the bottom of the furnace shell. The system for production of calcium carbide liquid with the induction furnace provided by the invention can make full use of the powder raw material that cannot be consumed by traditional airtight furnaces, and reduces the loss of powder.

Description

technical field [0001] The invention generally relates to the field of calcium carbide production in traditional coal chemical industry, in particular to an induction furnace and a system and method for producing calcium carbide liquid by the induction furnace. Background technique [0002] The raw materials used in the production of calcium carbide by the traditional closed furnace method mainly include quicklime and carbon materials. The particle size of quicklime is generally 5-40mm. The particle size of the carbon material is generally 3-20mm. Quicklime and carbon materials produce a large amount of powder (namely lime powder and coke powder) during the crushing process, accounting for about 5% of the furnace charge. The powder is easy to form a hard shell in the material layer, which reduces the resistance of the furnace charge and produces The branch current prevents the three-phase electrodes from being stably and deeply inserted into the charge. At the same time, ...
