Background technology
Traditional weight-loss method combustible content detection method is a kind of lab analysis method of off-line, and its incinerator adopts Muffle furnace usually, needs manually-operated.Owing to its heaviness, power consumption reasons such as high-temperature oxydation big, heat generating member make it can not be continuously, the long-term use, its structure also is not easy to cooperate executing agency to accomplish testing process automatically, so is not suitable for online detection occasion.
Summary of the invention
Technical problem to be solved by this invention is: provides that a kind of volume is little, the thermal efficiency is high, saves electric energy, and anti-oxidant, the life-span long, small-sized incinerator is used in the weight-loss method on-line analysis of accomplishing the calcination process automatically.
Solving the technical scheme that its technical problem adopts is: small-sized incinerator is used in a kind of weight-loss method on-line analysis; It is characterized in that it comprises:, the body of heater that the insulation filler is formed is set between interior boiler clothing and furnace outer body by interior boiler clothing, boiler clothing arranged outside furnace outer body; In the interior boiler clothing of said body of heater, burner hearth is set; Top at said body of heater is provided with top cover labyrinth, in the bottom of said body of heater lower sealing cover is set, and is equipped with the heat radiation diaphragm seal at the opening part of lower sealing cover; The lower end of power rail and crucible carriage is connected; Be positioned on the crucible carriage at the built-in crucible of burner hearth, the solid cap of cover is sealed and matched with the interior boiler clothing opening of burner hearth bottom on the crucible carriage, and it is interior and be positioned at the top of crucible that thermocouple stretches into burner hearth.
On said top cover labyrinth, be provided with on the body of heater and cover, be equipped with fixedly fixture block of thermocouple covering on the body of heater, thermocouple is fixture block clamping thermocouple fixedly.
The said Si-Mo rod that stretches in the burner hearth is that many U type Si-Mo rod series connection are distributed in the burner hearth.
In said cap, place and be placed on the filled insulation on the said crucible carriage.
Weight-loss method on-line analysis of the present invention exists with the advantage applies of small-sized incinerator: 1, drive the crucible of placing on crucible carriage and the crucible carriage for ease of power rail and insert burner hearth; Or in burner hearth, shift out; Size of burner hearth is confirmed according to the sampling quantity and the crucible size of 2-3 gram in the calcination space of burner hearth; Guarantee that heating space is little, heating is rapid, and heat loss is little; 2, adopt by dispel the heat the admittedly top of diaphragm seal, power rail and the bottom of crucible carriage of cover on power rail and be connected; The cap solid at crucible carriage cover is sealed and matched with the interior boiler clothing opening of burner hearth bottom, and the be sealed and matched integrated fire door of formation of the opening part of heat radiation diaphragm seal and lower sealing cover is positioned over the structure on the crucible carriage at the built-in crucible of burner hearth; Can be when sample being pushed to burner hearth central authorities; The heat that prevents little space burner hearth scatters and disappears from fire door, is employed in again between furnace outer body and the interior boiler clothing insulation filler is set, and can prevent that the heat of burner hearth scatters and disappears outside body of heater; 3, many U type Si-Mo rod series connection that are distributed in the burner hearth are connected with outside connected switch type dc source through busbar; Adopt the thermocouple feedback temperature in the heating process; Furnace temperature can be adjusted between 800 ℃-1000 ℃ as required, and Si-Mo rod at high temperature forms surperficial quartz film, does not reoxidize; 4, incinerator is when 20 ℃ of room temperatures, and when keeping constant fire box temperature and being 850 ℃, required operating power is merely 150W, and power is no more than 600W during cold start-up; Can in 5 minutes, reach 850 ℃, heating is fast, and its thermal efficiency is high; Thermal inertia is little, saves electric energy, service life.
