Abstract
What the present invention proposed is a kind of method and apparatus of self soda-returning, is applicable to soda ash production, is characterized in utilizing the Luo coil that is wrapped in steam calciner outside furnace to make soda ash transport burner back from the stove tail automatically.
The soda ash that is burnt the outlet of stove afterbody by the steam candle enspheres in the spiral tube that is wrapped on the body of heater through the discharging of stove tail, rotates with body of heater along tube wall and returns, and enters in the stove automatically by the burner supply ring.Cancelled original mechanical transport method, shortened process, minimizing equipment is reduced investment outlay and working cost, reduces noise, improves environment.
Description
The invention belongs to soda ash and return the improvement of carrying method.
Continue to use the mechanical transport method of the outer accumulation of salt in the surface soil before the present invention always.Most soda ash of steam roaster stove tail outlet will be transported in the stove again as the accumulation of salt in the surface soil, and the huge haulage system of a cover must be arranged.Its transport courses is that soda ash goes out calcining furnace from the stove tail and enters out the alkali worm conveyor, returns worm conveyor through the set worm conveyor.Chapelet is to the distributing auger transfer roller.Most soda ash as the accumulation of salt in the surface soil through accumulation of salt in the surface soil worm conveyor, advance the alkali worm conveyor and reenter the calcining furnace head, this is the typical process of Suhl dimension system alkali.This flow sheet equipment is many, and investment is big, and floor space is big, and the regular job expense is many, and power consumption is many, and maintenance workload is big, and the mechanical transport noise is big, and alkali dirt flies upward.
The objective of the invention is to cancel outer accumulation of salt in the surface soil transportation equipment, shortened process reduces noise, improves environment.
Main points of the present invention are that the soda ash of steam roaster afterbody outlet enspheres in the spiral tube that is wrapped on the body of heater through the discharging of stove tail, rotate with body of heater along pipe and return burner, enter in the stove automatically by the burner supply ring.
The method of this self soda-returning has shortened technical process greatly owing to cancelled whole accumulation of salt in the surface soil haulage system, has reduced equipment, has saved investment and working cost.
Below with reference to accompanying drawing invention is described in further detail.
Fig. 1 is the self soda-returning device.
Fig. 2 is the local stretch-out view of Fig. 1 stove tail discharging circle (3).
Fig. 3 is the local stretch-out view of Fig. 1 burner supply ring (4).
With reference to Fig. 1, the device of this self soda-returning has one or more spiral tube (1) to be attached to body of heater (2) outside, is convenient to clean spiral tube and maintenance calcining furnace internals.Its spiral tube cross section can be garden shape, square or other geometrical shapies.Its spiral tube (1) is a helix angle with the planar angle of body of heater (2) axis normal, and its helix angle must not surpass 45 °, is preferably between 20 °～40 °, to improve the mass transport ability.One end of this spiral tube is connected with stove tail discharging circle (3), and the other end is connected with burner supply ring (4).Its stove tail discharging circle (3) is the annular collar of an enclosed shape as shown in Figure 2, is fixed on the body of heater.This circle is divided into one or more snippets, and every section has an opening for feed (6), feed bin (7), spiral tube inlet (8), opening for feed (6) to be communicated with furnace inner space.This circle rotates with body of heater (2) according to the direction of arrow (5).The structure of its burner supply ring (4) as shown in Figure 3, and is identical with stove tail discharging circle (3), is fixed on the body of heater.The hop count of this circle is identical with stove tail discharging circle (3).Every section all has spiral tube outlet (9), feed bin (10), discharge port (11).Discharge port is communicated with furnace inner space.This circle rotates with body of heater according to arrow (5) direction.
When body of heater (2) rotated according to arrow (5) direction, soda ash was gone into feed bin (7) by the opening for feed (6) of stove tail discharging circle (3), was gone in the spiral tube (1) through spiral tube inlet (8) by feed bin (7) again.Soda ash is made downglide motion in spiral tube, progressively move to burner supply ring (4) and locate, and enters feed bin (10) by spiral tube outlet (9), is entered in the stove automatically by discharge port (11) again.
The self soda-returning device that stove tail discharging circle (3), spiral tube (1) and burner supply ring (4) are formed is all made of steel, and outside surface has thermal insulation layer, makes material fluidity good, has good insulation effect.Satisfy the requirement of the steam roaster accumulation of salt in the surface soil, guarantee long-term continuous operation, unblocked in the running, do not produce and scab, stop up.
Claims (5)
