Description
Technical field
The present invention relates to carbon brush processing technique field, more particularly, to a kind of sintering furnace that can reduce heat losses.
Background technology
Carbon brush, be motor, generator or other rotating machineries fixed part and rotating part between transmit energy or
The device of signal.Carbon brush is after compressing, it is necessary to be sintered, mechanical strength, reduction resistance the purpose is to improve product
And fix its geometry.Because the raw material of carbon brush include resin and pitch, therefore can be produced during high temperature sintering
The a large amount of dense smokes of life, the main component of the dense smoke is the particle flue dust such as resin and asphalt high-temperature treatment volatile matter, sulfide.This kind dense
Cigarette easily causes that carbon brush surface is contaminated, and influences product quality.
In order to solve the above problems, the Chinese patent of Patent No. ZL201410093605.X discloses a kind of carbon brush for electric machine
Sintering furnace internal structure, including sintering body of heater and flue, described flue include bonnet, crucible and base, the bottom of bonnet with
Base is connected by lock, the furnace chamber that bonnet is closed with formation in base, and multiple earthenwares have been stacked gradually from the bottom to top in furnace chamber
Crucible, left on each crucible can inside and outside ventilation gap, furnace chamber is provided with the top of described bonnet with the row connected outside body of heater
Flue, the circumference of base is provided with draw-in groove, and the lower end of bonnet is located in the draw-in groove of base, and river sand sealing is provided with draw-in groove.Above-mentioned side
When in use, the dense smoke produced in crucible can be discharged the sintering furnace that case is provided by smokejack in time, it is to avoid dense smoke pollution
The situation of carbon brush.
But, the smokejack in such scheme is directly connected with furnace chamber, by the swabbing action of smokejack, can not only be taken out
Go out dense smoke, the hot-air inside sintering furnace can also be taken away, cause largely to be lost in for the heat of heating crucible, so as to reduce carbon
The sintering rate of brush.
The content of the invention
The invention is intended to provide a kind of sintering furnace that can reduce heat losses, can solve the problem that existing apparatus are easily caused greatly
Amount heat losses, reduce the problem of sintering rate.
To achieve these goals, the present invention is provided can reduce the sintering furnace of heat losses, including body of heater and positioned at stove
Internal flue, is provided with thermocouple, heating rod and several crucibles in flue, several crucibles are vertically stacked, and are set on crucible
There is exhaust smoke hole, body of heater upper end is provided with cistern and fume extracting device, blow-off pipe is communicated with cistern；Also vertically it is provided with total in flue
Pipeline, the upper end of total pipeline is located at outside body of heater through flue and body of heater, and the upper end of total pipeline is connected by fume extracting device with cistern
Connect；Smoke exhaust pipe is communicated with crucible, smoke exhaust pipe is set around crucible wall, one end of smoke exhaust pipe is connected by exhaust smoke hole with crucible
Connect, the other end of smoke exhaust pipe is connected with total pipeline.
The know-why of the technical program and have the technical effect that：The technical program offer is a kind of can to reduce heat losses
Sintering furnace, including body of heater and the flue in body of heater.It is stacked in flue by by multiple crucibles, accounting for for crucible can be reduced
Ground area, saves factory building resource.Crucible is used to hold carbon brush to be sintered, and crucible is entered by the heating rod in flue
Row heating.During heating, the temperature of heating is detected by the thermocouple in flue, so as to reach control sintering temperature
The purpose of degree.
The smoke exhaust pipe that setting is connected with inside it on each crucible, can be by the effect of air extractor, by crucible
The dense smoke of generation is extracted out, it is to avoid dense smoke pollutes carbon brush.In addition, smoke exhaust pipe is set around crucible in this programme, dense smoke is with smoke evacuation
Pipe can surround crucible peripheric movement during flowing, because dense smoke has temperature higher, it is possible to being protected to crucible
Temperature.Again because total pipeline is directly connected by smoke exhaust pipe with crucible inside, by inside the only crucible that pipeline is taken away
Dense smoke, and being located at outside crucible is used to still stay in flue the hot gas of crucible heating, without reduction, therefore, this programme exists
While taking dense smoke away, will will not be taken away for the heat for heating so that sintering furnace will not be received to the heating process of crucible and taken out
The influence of gas.Additionally, when the dense smoke of lower section crucible is by the junction of top smoke exhaust pipe and total pipeline, due to the caliber of total pipeline
More than the caliber of smoke exhaust pipe, and the dense smoke speed in total pipeline, then the air pressure of the junction can be reduced, accelerate the smoke evacuation
The speed of the dense smoke discharge in pipe, is easy to smoke evacuation.
In addition, this programme is provided with the cistern connected with total pipeline in body of heater upper end, the dense smoke discharged by total pipeline is entered
Enter in cistern, the water in cistern precipitates by the particulate matter in dense smoke, so as to be cleaned to dense smoke.Absorb particle
The water of thing is discharged by blow-off pipe again, into sewage disposal device, completes the treatment of sewage.
In sum, the technical program is directly connected by by smoke exhaust pipe with crucible inside, and smoke exhaust pipe can be avoided to use
Taken away in the heat of heating, so as to reduce the loss of sintering furnace heat, sintering rate can be improved compared with prior art.This
Outward, the technical program is circumferentially positioned at crucible periphery by by smoke exhaust pipe, additionally it is possible to crucible is incubated by high temperature dense smoke,
Further keep the sintering temperature in crucible.
The following is the preferred scheme of such scheme：
Preferred scheme one：Based on base case, the smoke exhaust pipe is contacted with crucible wall so that high temperature dense smoke can be more prone to
Transfer heat to crucible, so as to reduce loss of the heat in transmittance process.
Preferred scheme two：Based on preferred scheme one, the smoke exhaust pipe is in the shape of a spiral so that smoke exhaust pipe winds in crucible outer wall
There is multi-turn, the contact area of smoke exhaust pipe and crucible can be increased, so as to extend soaking time of the smoke exhaust pipe to crucible.
Preferred scheme three：Based on preferred scheme two, the caliber of one end that the smoke exhaust pipe is connected with crucible is more than smoke exhaust pipe
The caliber of the one end being connected with total pipeline.When dense smoke is moved in smoke exhaust pipe, because caliber is less and less so that dense smoke is pressed
Contracting, the rubbing action between the particulate matter allowed in dense smoke strengthens, and so as to allow the temperature of dense smoke further to raise, and then improves dense smoke
To the insulation effect of crucible.
Preferred scheme four：Based on base case, the caliber of the caliber more than smoke exhaust pipe of the total pipeline.When dense smoke enters total
After pipeline, because the caliber of total pipeline is bigger so that dense smoke expands, the friction between the particulate matter allowed in dense smoke weakens, so that
Allow the temperature of dense smoke to reduce, reduce the heat that total pipeline is subject to, extend the service life of total pipeline.
Preferred scheme five：Based on preferred scheme four, between the flue and body of heater be filled with insulation material, reduce flue with
Heat exchange outside body of heater, so that the sintering temperature in keeping flue, reduces the consumption to the energy.
