During using being vertically arranged, agitating device is by the puddler and the blade being fixed on puddler being vertically arranged in mixing surge tank
Constitute.It is stirred by the blade that rotarily drives of vertical puddler.During using horizontally disposed mode, as shown in figure 1, stirring dress
Put and be made up of the puddler and the blade being fixed on puddler that are horizontally set on mixing surge tank lower inside.Puddler level
Rotational band movable vane piece is stirred.The stirring scope of horizontal alr mode can more fully cover mixing buffering pot bottom, more
Coke is desirably prevented in the localized clusters of mixing buffering pot bottom, and advantageously forms uniform Jiao's water mixed slurry and row
Go out.
Described piston-like movement mechanism can arrange a set of reciprocating piston mechanism, and the piston mechanism is arranged on defeated
Send in pipeline, or be arranged on and be connected in the housing of conveyance conduit, piston machine is driven using modes such as motor crank, hydraulic jacks
Structure is moved, so as to the burnt water mixed slurry in being forced into conveyance conduit or housing is moved along conveyance conduit.Piston-like movement machine
Structure can also arrange more than two sets piston mechanism alternate runs, wherein when a set of piston mechanism is retreated, before another piston mechanism
Move, so as to continual conveying.For efficient conveying, prevent burnt water mixed slurry from flowing back into mixing surge tank.In mixing
The exit of surge tank arranges valve, and the valve is opened when piston-like movement mechanism retreats, and flows out burnt water mixed slurry, and
Burnt water mixed slurry is promoted to close when conveying in the reach of piston-like movement mechanism.When more than two sets piston mechanism alternate runs of setting
When, valve can also relative set it is multiple, coordinate with the action of each piston mechanism.
In this utility model, each coke drum can be provided with a mixing surge tank, it is also possible to two coke tower configurations one
Individual mixing surge tank, such as, shown in Fig. 1, the first coke drum 2 and the second coke drum 3 share a mixing surge tank 9.It is burnt at two
During charcoal cone pulley stream cycle operation, mixing surge tank 9 is in running order all the time, improves the utilization rate of equipment.Using two coke
When tower shares the mode of a mixing surge tank, two coke drums 2,3 can be connected to by each independent burnt groove that slips respectively
The mixing surge tank.The burnt groove 22,23 that slips that two coke drums 2,3 connect can also be converged to into a conveying road as shown in Figure 1
Mixing surge tank is connected to after 24.
Gas piping can also be connected in the upper end of mixing surge tank 9, coke in surge tank will be mixed by gas piping and produced
Raw waste gas is delivered to exhaust treatment system 25 and carries out individual processing.
Basic procedure of the present utility model is：During decoking, coke drum bottom valve 7 is opened, start disintegrating machine 8, by decoking device
It is put in coke drum, starts decoking water pump 14 and devoke.Big lump coke is broken by the burnt aqueous mixtures Jing disintegrating machines 8 discharged from coke drum
It is broken, then mixing surge tank 9 is entered by slipping burnt groove.Agitating device 10 in mixing surge tank 9 stirs burnt aqueous mixtures, bottom
Piston-like movement mechanism 11 burnt aqueous mixtures be transported to into dehydration device 4 be dehydrated.After opening dehydration device blow-off valve 5, dehydration
Coke Jing batchers 6 afterwards go entrucking or belt feeder to transport out device.In mixing surge tank 9, Jing's excessive sewage overflows after filtering
Head piece flow to Sedimentation tank 12, and waste gas is discharged Jing after the process of exhaust treatment system 25.Sewage in dehydration device 4 also flows after filtering
To Sedimentation tank 12.The boosted pump 13 of water purification after the process of Sedimentation tank 12 lifts decoking water pot 1 and stores.When slipping burnt groove generation blocking
