Description
Technical field
The utility model relates to a kind of coating furnace fume extractor, particularly a kind of fume extractor of carbide alloy deep processing coating furnace equipment.
Background technology
In carbide alloy deep processing industry production, due to hard alloy coating product have that case hardness is high, wearability good, stable chemical performance, the characteristic such as heat-resistant oxidized, coefficient of friction is little and thermal conductivity is low, therefore high-end hart metal product all needs to carry out coating procedure.Along with the development of science and technology, also more and more higher to the requirement of product, in carbide alloy processing enterprise, the application of coating furnace is more and more extensive.Coating is a kind of material surface strengthening technology, is at relatively high temperatures, and mist and surface of the work interact, and forms a kind of metal or compounds solid state film or coating at surface of the work.In coating procedure, carbide alloy is after completing coating reaction work, and in discharge process, open in the process of heating reaction furnace cover and produce a large amount of heat smoke, temperature is about 200 ~ 300 DEG C.Because coating workshop is constant temperature and humidity workshop, and a large amount of high-temperature flue gas diffuses in coating workshop, causes significant impact by the process environments in workshop and air quality.This not only affects the quality of coating product, also will increase the operating cost of whole coating Workshop air conditioner system.And existing coating furnace fume extractor complex structure, involve great expense, smoke exhaust fan can not regulating air volume, and whole device smoke discharging effect is poor.Further, pure airs a large amount of in workshop can be discharged when discharging high-temperature flue gas by existing air exhausting device, the process environments of constant temperature and humidity in workshop is affected, adds the operating cost of air-conditioning.Therefore, design is a kind of convenient applicable, economical, energy-conservation, and the air exhausting device being simultaneously applicable to again constant temperature and humidity process environments is just necessary.
Summary of the invention
The purpose of this utility model is to provide a kind of fume extractor for hard alloy coating stove, affects workshop pure air quality, increases the shortcoming of operation of air conditioner expense when overcoming existing coating furnace equipment blow-on.
A kind of fume extractor for hard alloy coating stove, it is characterized in that: comprise centrifugation frequency blower fan, air draft airduct, electronic airtight control valve and exhaust fume collecting hood, exhaust fume collecting hood and air draft airduct adopt welding manner to be connected, safety dress during airduct pipeline adopts, the assembling of employing ground, integral hoisting mode are installed, electronic airtight control valve is installed on after the outlet side of air draft airduct, centrifugation frequency blower fan, to prevent outside flue gas from pouring in down a chimney in workshop, affects the process environments in workshop.
A kind of fume extractor for hard alloy coating stove, it is characterized in that: exhaust fume collecting hood is back taper mesa-shaped, be positioned at the bell place of coating reaction stove, comprise stainless steel inversed taper platform, stainless steel short tube, stainless steel band steel flange, stainless steel angle steel shirt rim, stainless steel upper end of short tube soldering stainless steel band steel flange, the large frustum place angle steel welding of stainless steel inversed taper platform forms stainless steel angle steel shirt rim with the stability of reinforced platoon's petticoat pipe.For ease of maintenance and the maintenance of enclosure, little frustum is by stainless steel short tube welded flange, and large frustum periphery adopts stainless steel angle steel group limit to strengthen supporting, and for making enclosure sound construction, can arrange lifting screw rod at corner place, stainless steel shirt rim.
For a fume extractor for hard alloy coating stove, it is characterized in that: electronic airtight control valve and centrifugation frequency blower fan arrange interlocking, can according to the size adjustment air draft air quantity of exhaust gas volumn, ensure the stable of workshop constant-temperature constant-humidity environment, energy-saving effect is good.
The utility model compared with prior art, its advantage is: the utility model effectively can collect the flue gas and hot gas that carbide alloy processing coating reaction stove distributes in the process of uncapping, the environmental energy in workshop is made to keep the constant-temperature constant-humidity environment of process requirements, can according to the size adjustment exhaust air rate of exhaust gas volumn, avoid the discharge of unnecessary pure air, reduce the operating cost of air-conditioning, energy-saving effect is remarkable.The utility model structure is simple simultaneously, easy to make, construction and installation facility.
