Background technology
At present, in 270 ㎡ wedge furnance produce realities, roasting technique dust rate is up to 8% -10% just to set flue dust
4-5 times of rate.Find through field investigation, cavity, zinc oxide at this occurs in multiple hearth furnace furnace roof exhanst gas outlet position siege charge level
Flue dust whole suction dust collecting systems, while most entered material and airborne dust are taken out by the flue gas of exhanst gas outlet in feed chute
Inhale, the dust rate for thereby resulting in recovery flue dust remains high, the high-fluorine chlorine fume amount taken out of packing is big, the reduction of zinc direct yield, separately
Outer surface cooler and sack cleaner load are larger, and surface cooler cooling smoke pipe hangs the serious flue gas exit temperature control difficulty of dirt, gathers dust
Workload is than larger.
Therefore, it is necessary to provide that the device of dust rate is reduced during a kind of wedge furnance baked for producing, it is many to meet
The Production requirement of thorax roaster.
The content of the invention
In order to overcome problem present in background technology, the utility model to provide a kind of dress of reduction multiple hearth furnace dust rate
Put, by the exhanst gas outlet of multiple hearth furnace install reduce multiple hearth furnace dust rate device, thoroughly avoid exhanst gas outlet just to
Siege material is aspirated by flue gas, reduces dust rate, reduces dust collecting system burden, extends the cycle of cleaning dust collecting system flue, is subtracted
Gather dust less the amount of labour, improve system process metal direct yield, extend sack cleaner pulse shaking cycle, extend pulse valve, cloth
Bag service life, reduces high voltage pulse compressed air consumption, realizes that improving metal direct yield reduces the purpose of production cost.
For achieving the above object, the utility model is achieved by the following technical solution：
The device of described reduction multiple hearth furnace dust rate includes that steel plate 1, channel-section steel 2, furnace flue gas export pre-buried foundry goods 3, spiral shell
Bolt 4, described steel plate 1 is square structure, and described channel-section steel 2 has four pieces, is separately mounted to four angles of square steel plate 1
Place, the upper end of channel-section steel 2 offers screwed hole 5, and furnace flue gas to be exported and also offer screwed hole 5 on pre-buried foundry goods 3, and channel-section steel 2 passes through
The bolt 4 matched with screwed hole 5 is fixedly mounted on furnace flue gas and exports on pre-buried foundry goods 3, and furnace flue gas export pre-buried foundry goods 3 pacifies
It is mounted on the exhanst gas outlet 6 of multiple hearth furnace.
Preferably, described channel-section steel 2 is fixedly mounted at four angles of steel plate 1 by the way of welding.
Preferably, diameter of the length of described steel plate 1 more than exhanst gas outlet 6, after steel plate 1 is connected with channel-section steel 2, steel plate
1 is located at the lower section of exhanst gas outlet 6, and leaves gap between exhanst gas outlet 6.
The beneficial effects of the utility model：
The utility model is arranged on the smoke outlet of multiple hearth furnace, thoroughly avoids exhanst gas outlet from just causing material quilt to siege
Suction, reduction dust rate reduces dust collecting system burden, extends the cycle of cleaning dust collecting system flue, reduces the amount of labour of gathering dust, and carries
High system process metal direct yield, extends the pulse shaking cycle of sack cleaner, extends pulse valve, cloth bag service life, subtracts
Few high voltage pulse compressed air consumption, realizes that improving metal direct yield reduces the purpose of production cost.Also, the utility model is filled
Simple structure is put, easy installation and removal can be reduced to the dust rate of multiple hearth furnace by 8-10% before by the utility model
3-4%, reduces the effect of dust rate substantially, is follow-up dust collecting system stable operation, creates good condition.
Description of the drawings
Fig. 1 is the utility model structural representation；
Fig. 2 is working state structure schematic diagram of the present utility model.
In figure, 1- steel plates, 2- channel-section steels, 3- furnace flue gas export pre-buried foundry goods, 4- bolts, 5- screwed holes, 6- exhanst gas outlets,
7- sieges, 8- materials.
Specific embodiment
In order that the purpose of this utility model, technical scheme and beneficial effect are clearer, below in conjunction with accompanying drawing, to this
The preferred embodiment of utility model is described in detail, to facilitate the technical staff to understand.
As shown in Figure 1 and Figure 2, the device of described reduction multiple hearth furnace dust rate includes that steel plate 1, channel-section steel 2, furnace flue gas go out
The pre-buried foundry goods 3 of mouth, bolt 4, described steel plate 1 is square structure, and described channel-section steel 2 has four pieces, is separately mounted to square
At four angles of steel plate 1, the upper end of channel-section steel 2 offers screwed hole 5, and furnace flue gas to be exported and also offer screw thread on pre-buried foundry goods 3
Hole 5, channel-section steel 2 is fixedly mounted on furnace flue gas and exports on pre-buried foundry goods 3 by the bolt 4 matched with screwed hole 5, and furnace flue gas go out
The pre-buried foundry goods 3 of mouth is arranged on the exhanst gas outlet 6 of multiple hearth furnace, and the length of described steel plate 1 is more than the diameter of exhanst gas outlet 6, steel
After plate 1 is connected with channel-section steel 2, steel plate 1 is located at the lower section of exhanst gas outlet 6, and gap is left between exhanst gas outlet 6, can so make cigarette
Gas enters into exhanst gas outlet 6 and is discharged from gap location, thus is avoided that exhanst gas outlet just to siege material.
