Description
Technical field
The present invention relates to dust pelletizing system apparatus fields, more specifically to a kind of transfer station feed bin discharging dusty gas
Dust-extraction unit.
Background technology
A kind of corollary apparatus that dust-extraction unit belongs to coke finished product dust pelletizing system is inhaled on transfer station feed bin discharging dusty gas top,
For playing the coke transfer station of storage cushioning effect between two seat height stoves, dust-extraction unit is inhaled on transfer station feed bin discharging dusty gas top
It is by cover top and transfer station feed bin lower end concrete platform by pushing up, i.e. feed bin discharge region is taken in transfer station feed bin discharging dedusting
The mode of strength dust suction utilizes the long feature of width of transfer station, is effectively sealed, transported to transfer station feed bin discharge region
It stands and sets top draft hood between silo discharge port and engine above the side in spatial domain, pipeline is arranged in side-draught hood lower end, carries out strength suction
The dusty gas that feed bin discharging generates is trapped in transfer station feed bin discharge region, improves coke by dirt on the spot to the maximum extent
The working efficiency of finished product dust pelletizing system dedusting, can be widely used for the industries such as steel, coking at present.
But the transfer station that container is carried for configuration train, because the container apical side height that train carries is higher (general
Compared with terrace >=3.71m in station), cause transfer station feed bin discharging narrow space, dust-extraction unit to be difficult to be arranged, and transfer station spaciousness
Region easily by surrounding beam wind (being commonly called as wild wind) influence, causes the worker work position cloud of dust to diffuse, seriously affects operating personnel
Physical and mental health, reduce labor productivity.The main problem of generation is as follows：
One, the discharging of transfer station feed bin causes dusty gas to drift everywhere with the wind due to a lack of dust-extraction unit, influences post and defends
It is raw；Even the Work places cloud of dust diffuse, be unable to ensure operating personnel be promptly and accurately aligned container carry out observation and material position smash it is flat
Operation influences to produce normal operation；
Two, the discharging of transfer station feed bin may influence to produce normal operation, while can lead to packaging due to a lack of dust-extraction unit
Coke overflows in case, and loss is serious, increases production cost；
Three, in container coke spilling, gently then influence transport operation, coke when serious on track will cause locomotive and
The safety traffic for playing carrying container, increases maintenance cost.
Invention content
1. technical problems to be solved
For existing in the prior art since dust-extraction unit setting caused by insufficient space is difficult, and transfer station spaciousness
Region easily by surrounding transverse direction wind effect, causes the cloud of dust to diffuse, and being unable to ensure operating personnel, observation and material position smash flat operation, shadow in time
The problem of ringing production normal operation, the present invention provides a kind of transfer station feed bin discharging dusty gas dust-extraction units.It can be real
Now efficient dust removing effects, simple in structure, convenient disassembly reduce labor intensity, and do not influence the normal production of locomotive container
Operation.
