Abstract
The utility model relates to an automatic material discharge device of lime kiln is characterized in that the discharging position of kiln body is in radial and a plurality of rotary type discharge rods are homogeneous distribution on the circumference of the kiln body, wherein each discharge rod is provided with a separated drive mechanism and a transmission rig, and an automatic control system is arranged for controlling each discharge rod on simultaneous turning or independent turning. Under the control of the system, each discharge rod can be turned simultaneously or independently, wherein the simultaneous turning guarantees each discharge rod to run in consistency, and the independent turning is convenient for the controller to adjust the problems concerning over-fast or too-slow of discharging in a or two position caused by the gain size of material etc. Thereby the discharge of lime kiln can be guaranteed to be even and balance without interior hole, non-offset, no multi-layer and no freezing, moreover, the ore coal on the furnace layers can be subsided equably, by which a necessary guarantee for getting stable quality lime is available.
Description
Technical field:
The utility model relates to the lime vertical kiln drawing mechanism.
Background technology:
At present, the discharge method of lime vertical kiln is varied, and wherein, the PLC full automatic control is all adopted in the discharging of import shaft kiln, and price is higher, and is common also only supporting in the enterprising enforcement usefulness of import shaft kiln.The discharge method of homemade lime vertical kiln comprises: manual draws, the discharging of automatically controlled vibration discharging machine, the tower discharging machine discharging of automatically controlled castor, and the discharging of manual revolution blowing bar.Wherein, manual revolution blowing bar is being that discharging is carried out in the revolution of blowing bar, although rotary type blowing bar is a kind of discharge method preferably, but, make the actual effect of this mode be difficult to performance because of adopting problems such as manual mode has the discharging inequality, labor strength is big, production efficiency is low, quality product can not be guaranteed.
Summary of the invention:
The utility model is for avoiding above-mentioned existing in prior technology weak point, a kind of lime vertical kiln self-emptying device being provided.
The technical scheme that the utility model technical solution problem is adopted is:
Constructional feature of the present utility model is on kiln body discharging position, be radially and on the circumference of kiln body, evenly arrange many rotary type blowing bars, each root blowing bar has independent driving mechanisms and transmission rig separately, and revolution synchronously of each blowing bar of control or independent rotating automatic control system are set.
The characteristics of shaft kiln lime are that particle diameter is bigger, generally between 30mm to 200mm, utilize lumpy material to pass through the characteristic of the easy self-locking putty of throat, when discharge port size and raw meal particle size size and blowing shank diameter proportion relation, material is in critical stationary state between discharge port and blowing bar.When coming back rotation blowing bar, the frictional force of blowing bar and material has changed critical stationary state, and material promptly descends along with the rotation of blowing bar, reaches the purpose of discharging.
Compared with the prior art, the beneficial effects of the utility model are embodied in:
1, the utility model has many blowing bars evenly to arrange on the circumference of kiln body, and, under system's control, each root blowing bar can turn round or independent revolution synchronously, its synchronous revolute function has guaranteed the work consistence of each root blowing bar, its independent revolute function is convenient to the control personnel and is regulated the individual bits that causes owing to reasons such as raw material granularities to deposit material too fast or cross the problem that waits slowly, thereby effectively guaranteed limestone kiln blanking uniform and stable, non-core pulling, non-migration, non-cross strata, non-clotted slag, mine coal of stove layer uniform settling are for the lime that obtains stay in grade provides necessary assurance.
2, the utility model no longer needs many people to work by hand, and only a people can finish relevant system's control, has both reduced labour intensity, has also improved quality product simultaneously.
3, the utility model is simple in structure, reliable operation.
Description of drawings:
Fig. 1 is the utility model feed back bar arrangement synoptic diagram in the kiln body.
Fig. 2 adopts the crank linkage driving system structural representation for the utility model.
Fig. 3 adopts crank connecting link rack and pinion drive mechanism structural representation for the utility model.
Fig. 4 is the utility model drive-motor pilot circuit schematic diagram.
Fig. 5 is the utility model drive-motor master loop schematic diagram.
Number in the figure: 1 kiln body, 2 blowing bars, 3 cranks, 4 rocking bars, 5 connecting rods, 6 tooth bars, 7 transmitting gears.
Embodiment:
Referring to Fig. 1, present embodiment is on the discharging position of kiln body 1, be radially and on the circumference of kiln body 1, evenly arrange many rotary type blowing bars 2, each root blowing bar 2 has independent driving mechanisms and transmission rig separately, be provided with control each blowing bar 2 turn round simultaneously or independence rotating automatic control system.
Referring to Fig. 2, in concrete the enforcement, electric motor driving and crank linkage driving system are set, with the machine shaft interlock be crank 3, radially connect firmly rocking bar 4 at the rod end of blowing bar 2, between rocking bar 4 and crank 3, connect with connecting rod 5.The velocity of rotation of crank 3 designs according to the blanking amount, more than 30rpm, can value be 30-60rpm generally.According to crank connecting link minimum pressure angle design theory, require the rocking bar pivot angle in 100 °, help satisfying the stress condition of tie point, increase the service life.Therefore, when design blowing bar revolution pivot angle is in 100 °, adopt this type of drive comparatively simple and convenient.
Referring to Fig. 3, in concrete the enforcement, electric motor driving and crank connecting link rack and pinion drive mechanism also can be set, with machine shaft interlock be crank 3, with driving rack 6 is slide block, connect with connecting rod 5 as between the tooth bar 6 of slide block and the crank 3, the transmitting gear 7 and the blowing bar 2 that are meshed with driving rack 6 connect firmly.
Greater than 90 °,, adopt this type of drive comparatively suitable in design blowing bar angle of revolution especially greater than 100 ° of degree.
In addition, same principle in concrete the enforcement, also can adopt strength or fluid power to drive, and radially connects firmly rocking bar 4 at the rod end of blowing bar 2, and the pistons reciprocating bar directly links with rocking bar 4 in cylinder or the hydraulic cylinder body.
Greater than 90 °, during especially greater than 100 °, it is comparatively suitable to drive crank connecting link rack and pinion drive mechanism mode with electric motor driving or strength or fluid power in design blowing bar angle of revolution.According to the requirement of minimum pressure angle, stress condition at this moment is better, helps prolonging the work-ing life of member.
Referring to Fig. 4, Fig. 5, every blowing bar 2 is driven respectively by same model motor M independently, and when pressing total button SB0, all motors rotate simultaneously, and can close down any one or a plurality of motor separately this moment by SB9～SB16 button; Also can disconnect SB0, press SB1～SB8 button arbitrarily, open any or a plurality of motor separately.
