Agent and auxiliary agent are simultaneously sent into finished product pulse bag filter 24, and " FCC catalyst+auxiliary agent " the finished product powder separated enters into
Product tune mixes storehouse 25, purified jet air emptying；Finished product tune mixes storehouse 25 as Philips's formula or wall-attaching type multitube gravity mixing material
Storehouse is multi-runner type Gravity Mixing Storage Bin.
The FCC catalyst of different batches in product storage tank 12 is separately stored in, finished product can be delivered to individually, two-by-two or simultaneously
Mixed storehouse 25 is adjusted to carry out, and tune is mixed, and concrete mode can be determined according to required trimmed size performance.
" FCC catalyst+auxiliary agent " powder in storehouse 25 is mixed into finished product tune, single warehouse receipt time can be carried out, mixed, single storehouse is adjusted repeatedly to adjust
Repeatedly adjust mixed in mixed, double storehouse.Wherein, single warehouse receipt time, which is adjusted to mix, is not turned on finished product conveying fan 29, in the work of multitube gravity mixing pipe
Under, " FCC catalyst+auxiliary agent " powder mixes the interior tune that only carries out respectively once in storehouse 25 in finished product tune and mixes, that is, passes through finished product discharge valve
26 draw off；Single storehouse, which repeatedly adjusts to mix, need to open finished product conveying fan 29, under the action of multitube gravity mixing pipe, " FCC catalyst
+ auxiliary agent " powder finished product tune mix in storehouse 25 adjust respectively it is mixed after, pass through corresponding finished product discharge valve 26 respectively and enter corresponding literary mound
In in conveyer 6 28；Surrounding air is respectively enterd after the supercharging of finished product conveying fan 29 in venturi conveyer 6 28 simultaneously；
Suction " FCC catalyst+auxiliary agent " powder is respectively fed in finished product pulse bag filter 24, and the powder after separation enters finished product tune
It adjusts and mixes respectively again in mixed storehouse 25, it is recyclable repeatedly until reaching performance homogenization.Finished product tune, which mixes storehouse 25, one to open one for rotation
Operation also in parallel can simultaneously operate；Double storehouses, which repeatedly adjust to mix, need to open finished product conveying fan 29, in the work of multitube gravity mixing pipe
Under, " FCC catalyst+auxiliary agent " powder finished product tune mix adjust in storehouse 25 it is mixed after, it is defeated that venturi is entered by finished product discharge valve 26
It send in device 6 28, while surrounding air enters after the supercharging of finished product conveying fan 29 in venturi conveyer 6 28, aspirates " FCC
Catalyst+auxiliary agent " powder is sent into finished product pulse bag filter 24, and the powder after separation, which enters finished product tune, to be mixed and adjusted again in storehouse 25
It is mixed.Two finished product tune is made to mix storehouse 25 to connect, then powder is recycled multiple between Liang Cang.
