Abstract

The utility model belongs to the technical field of carbon production furnaces and particularly relates to an open ring type roasting furnace flue structure which solves the problems that as a brick-making flue of the existing open-type roasting furnace is easy to crack, the flue is not tight, and the phenomena of negative pressure leaking and gas mixing are generated. The open ring type roasting furnace flue structure is a steel tube in the whole, is arranged in a furnace wall, two ends of the steel tube are provided with vent holes, the top of the steel tube is communicated with a well mouth of a flue, and a tar sediment part is arranged below the steel tube. The open ring type roasting furnace flue structure has the beneficial effects that the phenomenon that the flue is tight and the gas is not mixed can be overcome, and the brick-making flue is mainly replaced by a thick steel tube, so that the influence of expand with heat and contract with cold on the flue can be avoided, the flue is tight and the phenomenon of negative pressure leaking can be reduced.

Description

Open type ring-form calcining furnace flue structure
Technical field
The utility model belongs to the plain technical field of producing stove of charcoal, is specifically related to a kind of open type ring-form calcining furnace flue structure.
Background technology
Roaster is one of capital equipment of producing carbon product, presses the stove composing method and calculates, and flue should occupy about 40%; Because the plain production technology demand of charcoal, flue must have good air-tight state, and the phenomenon of collaborating can not be arranged; So flue must have airtight good, the function of not collaborating.
The roaster of at present domestic charcoal ink factory man basically all is to adopt brick flue, especially open roasting furnace.After having used a period of time, receive the phenomenon influence of expanding with heat and contract with cold and can cause flue the crack to occur, make the flue leakiness, produced to run and leaked negative pressure and collaborate phenomenon.Normal operation produces harmful effect to the roasting furnace chamber, is in particular in following several respects:
1, because the flue seal is bad, furnace chamber running limited amount is generally Room 6 running, and can not increases, and output is not increased.
2, leak negative pressure because of running, cause the furnace chamber fire path temperature can not in time, often not catch up with the assigned temperature of curve, make the temperature of back furnace chamber undesired, serious to the influence of the product quality in the furnace chamber, phenomenons such as volume density is low, resistance is low as occurring easily, crackle.
3, the flue collector negative pressure is mainly produced by the blower fan running, and flue collector runs the leakage negative pressure appearance makes blower fan turn round in peak load, has increased power consumption.And aspect the natural gas use, Yin Gaowen fire negative pressure is not enough, makes the bad liter of temperature, and natural gas can not fully burn, and has increased energy consumption.
4, because of the flue collector leakiness, serious to quirk influence near it, so aspect shove charge, also can only consider pickled product, and can not consider the die mould article.Like this product yield is influenced to some extent, but also increased the consumption of natural gas.
Summary of the invention
The utility model makes the flue leakiness for the crack appears in brick flue easily that solve existing open roasting furnace, produces the problem of leaking the negative pressure and the phenomenon of collaborating of running.
The utility model adopts following technical scheme to realize:
A kind of open type ring-form calcining furnace flue structure is characterized in that described flue is whole steel pipe, is arranged within the furnace wall, and the steel pipe two ends are provided with blow vent, and steel pipe top is communicated with the flue well head, and the steel pipe below is the tar place of settling.
The relative prior art of the utility model has following beneficial effect: having overcome the airtight phenomenon of not collaborating of brick flue, mainly is to replace brick flue by thick pipe just, and the influence to flue of so just having avoided expanding with heat and contract with cold makes flue closely knit, has reduced and has run the leakage negative pressure appearance.
Description of drawings
Fig. 1 is the structural representation of the utility model
Among the figure: 1-waste gas junction, 2-steel pipe, 3-blow vent, 4-tar place of settling, 5-flue well head, 6-furnace wall.
The specific embodiment
Further specify in conjunction with the specific embodiment of accompanying drawing to the utility model, embodiment is used for explaining the utility model, rather than it is done any restriction.
Open type ring-form calcining furnace flue structure, described flue are whole steel pipe 2, are arranged within the furnace wall 6, and steel pipe 2 two ends are provided with blow vent 3, and steel pipe 2 tops are communicated with flue well head 5, and steel pipe 2 belows are tar place of settling 4.
The structure of the utility model is used for the open type ring-form calcining furnace, brings following effect:
1, furnace chamber operation quantity can be increased to Room 7 by Room 6, and output is improved greatly.
2, make the temperature of high temperature fire catch up with assigned temperature normally, reduced the undesired of back furnace chamber temperature, product quality has been improved greatly, reduced percent defective.
3, tight because of flue collector, negative pressure has been increased, the load of blower fan has reduced, so reduced power consumption, temperature also can normally be caught up with assigned temperature, the natural gas flare does not outwards emit, and has reduced unnecessary waste.
4, solve the subject matter that can not adorn the die mould article that quirk causes near flue especially, promoted roasting article output, reduced the unnecessary consumption of natural gas of same stove and other several casees.
The utility model successfully uses at the roaster in applicant's roasting workshop, and up to now, flue again not to be found to have to collaborate to lose the phenomenon of negative pressure, and effect all reaches very satisfied index.
