Description
The present invention relates to a kind of low quality coal is produced glass Mosaic without the air blast function heat exchange-type semi-gas kiln for glass mosaic that is used for directly burning.
The at present existing stove of producing glass Mosaic no matter be abroad or at home, all is with heavy oil, coal gas and the electricity thermal source as melt raw material.We are domestic and since heavy oil to fire power strong, the pressure in the melting furnaces is malleation, the feed liquid of fusion can spray from fluid port with the tongues of fire, liquation can be flowed out automatically smoothly, the free from dust polluted product, guaranteed product quality, burning heavy oil is the main stove form of producing glass Mosaic.Though it is domestic have a lotus flower stove that can directly burn coal, main because the little and poor product quality of output has influenced its development.And, between the age of consulting, find the U.S., Britain, France, Japan, Germany, the Soviet Union, China by to year March in September, 1985 to 1988 Chinese patent gazette and the relevant retrieval of 1974 to 1987 Derwent companies " world patent abstract " ... there were similarly patent application in 27 countries and international monopoly tissue and European Patent Organization.
Existing RF stove is to be chief component by oil depot, oil pump, steam boiler, hot oil machine, oil filter, oil pressure gauge, air gauge, spray gun, shallow inclined melting furnaces, three fiery four wind or four fiery tendencies, smokejack and air blast, the subject matter of its existence:
1, heavy oil supply anxiety, burning heavy oil cost height.
2, equipment complexity, the cost height of stove.
3, power consumption is big, automatically controlled stove temperature, as had a power failure 5 minutes, temperature reduces by 300 ℃ at least, and the temperature that returns to normal production needs 1 hour.
4, naked light heavy oil stove poor stability does not meet safety requirements.
5, environment also had pollution.
The lotus flower stove claims the garden stove again, and by the pincers pot annular array that 7～8 refractory materials are made, each can hold 80～100 kilograms of liquations, wind assembling set, combustion chamber air blast and smokejack is chief component, can burn coal or heavy oil.The problem that exists:
