Description
Technical field
The utility model relates to a kind of kiln top feeder of stove equipment, particularly gas combusting limestone kiln, belongs to the stove equipment technical field.
Background technology
Advantages such as lime shaft kiln is production metallurgy with the main kiln type of lime, and it has less investment, the construction period is short, working cost is low, easy and simple to handle and being adopted by many steel production enterprise.Lime shaft kiln is provided with feeder at Yao Ding, mainly is comprised of feeding chute (1), feed gate (2), hoisting system (3), and its structure as shown in Figure 1.Fill the dolly of building stones through promoting, pour building stones into feeding chute (1), hoisting system (3) is opened feed gate (2), and building stones are packed in the kiln.Because malleation is higher in the gas combusting limestone kiln kiln, this structure exists feed gate (2) when opening building stones and entering in the kiln, and the dust in the kiln can escape, and airborne dust is very large, and it is the primary pollution source that lime shaft kiln pollutes surrounding environment.
Summary of the invention
The utility model provides a kind of lime shaft kiln kiln top feeder of realizing dust Control.
A kind of lime shaft kiln kiln top loading device, its structure be as shown in Figure 2: it is to be made of bell (4), batch can (5), hopper (6), chute (7), bell drive unit (8), dust excluding hood (9), rope sheave system (10), bell Weighting system (11).Dust excluding hood (6) covers chute (4), and chute (4) docks with hopper (3), and hopper (3) docks with batch can (2), it is characterized in that: dust excluding hood (9) is connected to the ventilation and dust removal pipe and takes the discharging airborne dust away; Bunker gate (13) forms double-layer seal with bell (1) for the building stones that enter in the kiln, thereby avoids the interior dust of kiln to escape.

Fig. 2 is the utility model structural representation;
Fig. 3 is the bunker gate structural representation;
Fig. 4 is bell driving device structure synoptic diagram.
Number in the figure is expressed as follows: 1, feeding chute; 2, feed gate; 3, hoisting system; 4, bell; 5, batch can; 6, hopper; 7, chute; 8, bell drive unit; 9, dust excluding hood; 10, rope sheave system; 11, bell Weighting system; 12, equaler; 13, Yao Ding; 14, bunker gate; 15, gate hydro-cylinder; 16, gate limit switch; 17, bell hydro-cylinder; 18, bell limit switch; 19, reflector; 20, truck approach switch.
Embodiment
In conjunction with the embodiments embodiment of the present utility model is further described:
The lime shaft kiln when filling with substance, when building stones promoted through approach switch (20) through truck, bunker gate this moment (14) was opened, and bell (4) is in the closed position, and building stones are in chute (7) enters batch can (5).Bell (4) is positioned at batch can (5), and it is by bell hydro-cylinder (17) and the common driving of bell Weighting system (11), and signal is controlled and provided to bell hydro-cylinder (17) working stroke by bell limit switch (18).Because bell this moment (4) is in the closed position, the dust in the kiln can not escape by opening for feed.Truck returns to charging after unsnatching a car material, and during through approach switch (20), bunker gate (14) cuts out.The keying position of bunker gate (14) is by gate limit switch (16) control, and is accurate to guarantee keying.Be provided with reflector (19) in the batch can (5), it is more reasonable that the interior material of batch can is distributed.Accept several batches of building stones when batch can (5), when the building stones in the tank reached set(ting)value, bell (4) was opened, and building stones distribute to obtain the more uniform bed of material within reflector (19) is packed kiln into.The keying position of bell (4) is controlled by bell limit switch (18).Bunker gate this moment (14) cuts out.Dust in the kiln is sealed in the batch can, can not escape.Bunker gate (14) has formed double-layer seal with bell (4) for the building stones in the kiln like this, has effectively protected environment.Hopper (6) is provided with bunker gate (14), and bunker gate is driven by gate hydro-cylinder (15), controls and provide signal by gate limit switch (16).During the truck discharging, have airborne dust and emerge, bunker gate this moment (14) is shown in an open position in addition, and the dust that is sealed in the batch can (5) also can be overflowed, and is located on the dust excluding hood (9) herein and is connected to the ventilation and dust removal pipe, these dust can be taken away.Dust excluding hood (9) is connected to equaler (12) and is connected with batch can (5), can prevent bell (4) detrimentally affect that batch can (5) internal pressure rises equipment is caused when being in open mode.For guaranteeing that bell (4) under any circumstance can both close the jail, is provided with bell Weighting system (11).Bell (4) links to each other with bell Weighting system (11) by rope sheave system (10), and bell (4) is by hydro-cylinder (17) and Weighting system (11) acting in conjunction, with retort (5) sealed bottom.Also can guarantee device security in the state of accident.
