Background technology
Roller kilns are that a kind of rotation that utilizes roller rod carries goods to realize quantity-produced roasting apparatus.Owing to not using kiln car, compared with conventional tunnel kiln, reduced because kiln car is taken away the heat-energy losses that part heat produces, improved the thermal efficiency; And because roller rod all can heat up and down, kiln temperature is even, has shortened the firing period of product, be a kind of energy-efficient roasting apparatus, extensive in sector applications such as building, pottery, chemical industry.Roller kilns were prepared industry at catalyst and were also obtained larger application recent years, the transmission system of roller kilns main body is very ripe at present, the transmission of main employing differential helical gear multistage, frequency converter adds PC control mode, in material automatic mounting feeding disk, then the transmission of roller rest rod completes into the automated procedure of kiln, roasting and kiln discharge, but the automatization level of kiln entirety is also poor, after the discharging of charging tray kiln discharge, need manually charging tray to be transported to into Yao Chu, can not realize automatic cycle.
Chinese patent CN201120385475.9 discloses a kind of turning device for roller kiln, as the circulation for charging tray, carries, and this turning device need to arrange more roller rod and drives structure, complex structure, and transfer efficiency is low, and floor space is large.Chinese patent CN201110100924.5 discloses a kind of roller kilns of full-automation, these roller kilns adopt automatic turning machine and manipulator automatic loading, discharge mechanism to realize the automatic cycle of charging tray, because this turning machine can only be arranged on the side of roller kilns, floor space is large.
Summary of the invention
Technical problem to be solved in the utility model is that existing roller kilns exist the low and complex structure while adopting automatic turning machine of automaticity, and the problem that floor space is large, provides a kind of new roller kilns turn-around.It is high, simple in structure that this roller kilns turn-around has automaticity, the advantage that floor space is little.
For solving the problems of the technologies described above, the technical solution adopted in the utility model is as follows: a kind of roller kilns turn-around, and described turn-around is arranged between the external bottom of roller kilns, roller kilns entrance and exit; Described turn-around comprises kiln tail lift, bottom pipeline, kiln hood lift, unloader and control system; Wherein, kiln tail lift is arranged on roller kilns exit, and kiln hood lift is arranged on roller kilns import department, is provided with bottom pipeline between kiln tail lift and kiln hood lift; Unloader both can be arranged at kiln tail lift place, also can be arranged at kiln hood lift place; Control system is connected with kiln tail lift, bottom pipeline, kiln hood lift, unloader.
In technique scheme, kiln tail lift and kiln hood lift include a hoistable platform, high-order inductive switch, and low level inductive switch adopts motor to drive and makes its rising and drop to assigned address, hoistable platform is comprised of live-roller, and by its rotating of Electric Machine Control.
In technique scheme, bottom pipeline comprises guide rail, the platform that can move along guide rail, platform draw-gear, position of rest and acceleration and deceleration inductive switch.
In technique scheme, preferred version is that the platform that can move along guide rail adopts a dolly with roller, and platform draw-gear is the cylinder that drives of a variable-frequency motor and is around in the steel wire rope on cylinder, and steel wire rope two ends are connected with dolly.
In technique scheme, unloader is arranged at kiln hood lift place.
In technique scheme, control system adopts PLC controller, and frequency converter and motor, as controlling output system, are realized the automation control of turn-around by the detection to inductive switch signal and feedback.
The utility model, owing to having adopted turn-around design, can be realized the automatic cycle of charging tray, and automaticity improves greatly, has reduced labour intensity.Compared with adopting automatic turning machine, simple in structure, floor space is considerably less, has obtained good effect simultaneously.
Accompanying drawing explanation
Fig. 1 is the schematic flow sheet of the utility model roller kilns turn-around.
In Fig. 1,1 is kiln tail lift, and 1a is hoistable platform, and 1b is high-order inductive switch, and 1c is low level inductive switch; 2 is kiln hood lift, and 2a is hoistable platform, and 2b is high-order inductive switch, and 2c is low level inductive switch; 3 is bottom pipeline, and 3a is guide rail, and 3b is dolly, and 3c is platform draw-gear, and 3d is steel wire rope, and 3e and 3h are position of rest inductive switch, and 3f and 3g are acceleration and deceleration inductive switch; 4 is unloader, and 5 is charging tray, and 6 is roller kilns.
The following examples are described further with regard to the utility model, but the utility model is not subject to the restriction of embodiment.
The specific embodiment
[embodiment 1]
By Fig. 1, design roller kilns turn-around, when the charging tray 5 that catalyst is housed after the interior roasting of roller kilns 6 completes with roller rod transmission kiln discharge and be delivered to the hoistable platform 1a of kiln tail lift 1, kiln tail lift 1 stops while dropping to low level inductive switch 1c position automatically, live-roller rod on hoistable platform 1a rotates charging tray 5 is delivered to the dolly 3b on the pipeline 3 of bottom, platform draw-gear 3c moves to kiln hood direction by setpoint frequency along guide rail 3a by steel wire rope 3d trailer wagon 3b, when kiln tail lift 1 rises to high-order inductive switch 1b position simultaneously, automatically stop, wait for next charging tray,
When dolly 3b moves to inductive switch 3f, starting to accelerate to gradually setpoint frequency then keeps constant speed to move, when moving to inductive switch 3g, dolly 3b starts to be decelerated to gradually setpoint frequency, when dolly 3b moves to position of rest inductive switch 3h, stop mobile, live-roller rod on the hoistable platform 2a of kiln hood lift 2 rotates charging tray 5 is delivered on hoistable platform, then kiln hood lift 2 starts to rise, when kiln hood lift 2 rises, platform draw-gear 3c moves to kiln tail direction by setpoint frequency along guide rail 3a by steel wire rope 3d trailer wagon 3b, when dolly 3b moves to inductive switch 3g, starting to accelerate to gradually setpoint frequency then keeps constant speed to move, when moving to inductive switch 3f, dolly 3b starts to be decelerated to gradually setpoint frequency, when dolly 3b moves to position of rest inductive switch 3e, stop mobile, wait for next charging tray,
Kiln hood lift 2 stops while rising to high-order inductive switch 2b position automatically, live-roller rod is delivered to unloader 4 discharging of overturning by charging tray 5, after discharging completes, unloader 4 resets, charging tray 5 is first delivered to hoistable platform 2a by live-roller rod, being delivered to roller kilns 6 enters kiln section and carries out auto feed again, when lift 2 drops to low level inductive switch 2c position, automatically stop simultaneously, wait for next charging tray.
So far, charging tray completes from kiln discharge, carriage return, discharging, the automatic cycle process of entering kiln, enters the wait state of next circulation.
This roller kiln is long is 45m, and wide outside kiln is 2.3m, and the wide 1.2m of roasting charging tray, adopts the design of this turn-around, takes full advantage of the space of kiln body bottom, accounts for hardly area.
[comparative example 1]
The circulation that adopts existing roller kilns automatic turning machine to realize charging tray is carried, and at least in roller kilns one side, needs 45m × 1.2m=54m
2floor space.
By relatively, adopt roller kilns turn-around design of the present utility model, can realize the automatic cycle of charging tray, automaticity is high, simple in structure, and floor space is considerably less, has obtained good effect.
