Problems solved by technology

In this process, the high-temperature calcium oxide just out of the kiln must first be cooled from 400-500°C to room temperature for transportation, and after entering the calcium carbide furnace, it must be heated to 1900-2200°C by arc heat and resistance heat, which greatly wastes energy. The particle size of the calcium oxide just out of the kiln is between 30 and 50mm, which meets the feeding requirements of the sealed calcium carbide furnace, but after a long period of storage, it will absorb wate...

Embodiment Construction

[0013] The method of the present invention includes the following steps:

[0014] 1. The high-temperature calcium oxide from the stewing tank is weighed with an automatic scale and poured into the insulated narrow-gauge truck. The traction device of the insulated narrow-gauge truck is transported to the vicinity of the calcium carbide furnace through the track, and is lifted by the monorail crane to the top of the calcium carbide furnace. Feed material to the ring bin through the ring feeder;

[0015] 2. After calcium oxide is added to the calcium oxide annular silo, the annular silo's inlet is closed, and nitrogen is filled to replace the air. After the replacement is completed, the unloading opening is opened, and the feeding tube is used to feed the calcium carbide furnace;

[0016] 3. After the coke is crushed, sieved, and metered, it is added to the coke ring silo through belt conveyors, elevators and other equipment. The ring silo's inlet is closed and nitrogen is filled to rep...

Abstract

The invention relates to a thermal feeding device for a calcium carbide furnace. The device is used for directly feeding calcium oxide of 400-500 DEG C discharged from a lime kiln stewing tank into a dump truck without cooling, crushing or screening, carrying into an improved annular stock cabin through a track and a crane, mixing with coke in a feed pipe, and feeding a mixture into an enclosed calcium carbide furnace for producing calcium carbide. Due to the adoption of a process disclosed by the invention, the conveying and feeding ways of calcium carbide furnace charge are improved, and the conveying and feeding safety of the calcium carbide furnace charge is enhanced; and meanwhile, the temperature of calcium oxide entering the calcium carbide furnace can be up to 400-500 DEG C, so that heating time in the calcium carbide furnace is reduced, and the energy consumption of the calcium carbide furnace is lowered.

Description

technical field [0001] The invention relates to a calcium carbide production method and equipment, in particular to a calcium carbide furnace hot feeding method and device. Background technique [0002] The existing calcium carbide furnace feed is cold feed, that is, after the calcium oxide produced by the lime kiln is cooled to room temperature, it is crushed, screened, and measured, mixed with the treated coke in proportion, and conveyed by belt conveyor and screw. Machines, elevators and other equipment are sent to the ring feeder of the calcium carbide furnace into the furnace material storage hopper, and are thrown into the calcium carbide furnace through the feeding pipe. In this process, the high-temperature calcium oxide just out of the kiln must first be cooled from 400-500°C to room temperature for transportation, and after entering the calcium carbide furnace, it must be heated to 1900-2200°C by arc heat and resistance heat, which greatly wastes energy. The parti...
