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
The present invention relates to calcium carbide working method and equipment, particularly a kind of furnace of calcium carbide hot feed method and device.
Background technology
Existing furnace of calcium carbide charging all is a cold feed; Be after the quicklime that produces in the limestone kiln is cooled to normal temperature; After broken, screening, metering; With the coke proportional mixing of handling well, the annular charging machine of delivering to furnace of calcium carbide through equipment such as rotary conveyor, worm conveyor, lifts gets into the furnace charge hopper, throws in the furnace of calcium carbide through commissioning pipe.In this process, just the high temperature oxidation calcium of kiln discharge at first will be cooled to normal temperature so that carry by 400 ~ 500 ℃, leans on arc heat, resistance heat to be heated to 1900 ~ 2200 ℃ again after getting into furnace of calcium carbide, has wasted energy greatly; Just the quicklime granularity of kiln discharge meets closed calcium carbide furnace charging requirement between 30 ~ 50mm, but stores through long-time, can absorb water, with air in CO
2Cause caking Deng reaction, advancing needs broken, screening before the furnace of calcium carbide; In addition, furnace of calcium carbide furnace charge course of conveying is not airtight, causes dust pollution easily; Rotary conveyor skids easily or is stuck, and causes danger; Original annular feed bin stopping property is poor, causes CO, H in the furnace of calcium carbide easily
2Leak Deng inflammable gas and to cause and catch fire, explode, poor stability.
Summary of the invention
The objective of the invention is to overcome the deficiency of prior art, a kind of furnace of calcium carbide hot feed method and device are provided.The present invention realizes according to following proposal:
A kind of furnace of calcium carbide hot feed method; The high temperature oxidation calcium that limestone kiln stewingization jar comes out is without cooling, broken, screening; The trolley of directly packing into after the metering is transported in the annular feed bin through track and crane, is mixed into closed type calcium carbide furnace at commissioning pipe and coke and produces calcium carbide;
A kind of furnace of calcium carbide hot feed device; Comprise the annular feed bin that is positioned at the closed calcium carbide furnace top; 400 ~ 500 ℃ the high temperature oxidation calcium that limestone kiln stewingization jar comes out is directly packed into, and top is reinforced, the airtight insulation decauville tub of bottom discharge, is promoted to the furnace of calcium carbide top through crane, pours annular charging machine into;
The annular feed bin has two groups, is respectively applied for quicklime and coke feed; The annular feed bin respectively has an input and output material pulse valve up and down, and the side is provided with gas displacement and imports and exports.
Through the application of apparatus of the present invention, the high temperature oxidation calcium heat that the limestone kiln is produced is able to whole utilizations, reduces the furnace of calcium carbide energy consumption; Quicklime need not store for a long time, has reduced storing device, prevents that also quicklime is at the storage process mesometamorphism; Links such as quicklime fragmentation, screening have been reduced; Quicklime conveying process stopping property increases, and annular feed bin changes fully-closed and logical nitrogen protection into, has reduced the dust pollution of conveying process, has increased the security that furnace of calcium carbide feeds intake; It is simple that this frock is put equipment, easy and simple to handle, and cost is low, safe.
