Embodiment
Below against accompanying drawing, by the description to embodiment, embodiment of the invention is made further details of
Explanation, it is therefore an objective to help those skilled in the art to have to inventive concept of the invention, technical scheme more complete, accurate and go deep into
Understanding, and contribute to its implementation.
As depicted in figs. 1 and 2, the invention provides one kind to store up burnt tower coke discharging mouth dust exhaust apparatus, including cleaning shaft 4, use
Store up the both sides of coke discharging mouth 6 of burnt tower 1 in the dust absorption fan and being arranged at for providing suction and be used to guide in dust caused by coke discharging
Dust shield 2 into cleaning shaft 4, dust shield 2 have the height that the height of suction port 24 and suction port 24 is higher than coke discharging mouth 6.
Specifically, as depicted in figs. 1 and 2, the burnt internal reservoir coke of tower 1 is stored up, coke discharging mouth 6 is located at the bottom for storing up burnt tower 1,
There is a certain distance in the compartment 5 of train or automobile that coke discharging mouth 6 is used to load coke apart from lower section, stores up the coke warp in burnt tower 1
Coke discharging mouth 6 is fallen in the compartment 5 of lower section, and dust can be produced during coke discharging.Dust shield 2 be located at the both sides of coke discharging mouth 6 and
Positioned at the top in compartment 5, dust absorption fan is used to vacuumize cleaning shaft 4 and dust shield 2, produces negative pressure region, forms suction,
The suction can siphon away caused dust during coke discharging.Suction port 24 is located at the top in compartment 5, suction port 24 and external environment
Connection, after dust absorption fan operating, the air in environment is inhaled into dust shield 2 and cleaning shaft 4, store up the coke discharging mouth 6 of burnt tower 1 with
It is produced from down between dust shield 2 and the dust-absorbing airflow of upper flowing, dust-absorbing airflow begins to flow to coke discharging mouth 6 from below at compartment 5
Both sides, dust-absorbing airflow by dust caused by coke discharging bring into dust shield 2 and cleaning shaft 4 in, the most dust at last of cleaning shaft 4
It is delivered in the dust collecting box or dust collecting sleeve of specified location and is collected, so as to avoid diffussion of dust into environment, reduces ring
Pollute in border.
As depicted in figs. 1 and 2, the dust exhaust apparatus of 1 coke discharging mouth of storage Jiao tower 6 of the invention also include be arranged at cleaning shaft 4 with
Valve 3 between dust shield 2, valve 3 are connected with cleaning shaft 4 and dust shield 2.Cleaning shaft 4 is located at the lower section of dust shield 2,
