The clear 68-79533 of Japan Patent has disclosed a kind of feeding technique, is to adopt high-capacity pump that catalyst slurry is played circulation, and then utilizes a kind of equipment that is referred to as rotary actuator that the sub-fraction in the internal circulating load is added polymeric kettle by switching pulse.This mode flow process complexity, the device fabrication difficulty is big, involves great expense, and controls very unreliable.
Order of the present invention has proposed a kind of device and process of auxiliary agent auto feed just in order to solve weak point of the prior art.The present invention can make automatic, continuous, the stable adding paradigmatic system of slurry, reinforced frequency adjustable, and feeding quantity is adjustable, adopts approximately continuous pulsed reinforced, and stable polymerization reaction is carried out, and satisfies the demand of continuous reacting device.
The object of the present invention is achieved like this:
The device of auxiliary agent auto feed, comprising compositions such as catalyst slurry jar, catalyst guide-can, catalyst tank and pipelines, catalyst slurry jar, catalyst guide-can, catalyst tank and feeder are through the pipeline series connection together, feeder connects solvent and threeway again respectively, and material is gone into polymeric kettle by threeway place.
Purpose of the present invention can also be further perfect by following steps:
Feeder in this device is a ball valve, vertical direction at the valve cross central line has two holes, different beyond the Great Wall apertures stopper in the hole of the interior roating sphere of valve, in order to adjusting feeding quantity, rotary cylinder drives in the valve bead by connecting axle and does 90 ° of reciprocating motions.
The process of auxiliary agent auto feed is:
1. open valve, system is rinsed well with solvent;
2. open valve, have inert gas that system's displacement is clean;
3. open valve, allow slurry in the catalyst slurry jar enter catalyst guide-can, catalyst tank and between pipeline;
4. after about 5～8 minutes, solid has sunk in the catalyst guide-can in the slurry, at this moment shut off valve;
5. start the timer of solvent pump and magnetic valve, a Pressure gauge is adorned in the solvent pump outlet, a pressure return valve is housed between the entry and exit of solvent pump, when the feeder material feeding, after building the pressure, the solvent pump outlet returns stream, the solvent pump startup dashes the slurry in the feeder to threeway place when the feeder discharging, goes into polymeric kettle by suitable fast material then.
The present invention has 2 width of cloth accompanying drawings, and wherein Fig. 1 is a most preferred embodiment of the present invention, also can make the accompanying drawing of specification digest.
Fig. 1, charging technology flow chart;
Fig. 2, feeder structural representation.
The present invention compared with prior art has following advantage: can make automatic, continuous, stable the adding of slurry Enter paradigmatic system, reinforced frequency is adjustable, and feeding quantity is adjustable, is specially adapted to present other technology solution never The auto feed of trace assistant, adopt approximately continuous pulsed reinforced, stable polymerization reaction is advanced OK, satisfy the demand of continuous reacting device.
Below in conjunction with accompanying drawing most preferred embodiment of the present invention is described further:
The technological process of most preferred embodiment of the present invention as shown in Figure 1, solid additive is made into certain density slurry with solvent in catalyst slurry jar 10, stirred by agitator.Feed in raw material as follows;
Open valve 1, with solvent system is rinsed well, waste liquid is discharged by valve 2; Open valve 3, with inert gas that system's displacement is clean; Open valve 4,5,6, allow the slurry in the catalyst slurry jar 10 enter catalyst guide-can 11, catalyst tank 12 and between pipeline; After about 5～8 minutes, solid has sunk in the catalyst tank 12 in the slurry, at this moment shut off valve 4,5; Start the timer of solvent pump 14 and magnetic valve, a Pressure gauge is adorned in solvent pump 14 outlets, a pressure reflux pump 21 is housed between the entry and exit of solvent pump 14, when feeder 13 material feedings, after building the pressure, solvent pump 14 outlets return stream, solvent pump 14 startups dash the silt in the feeder 13 to threeway 15 places when feeder 13 dischargings, are entrained into polymeric kettle by suitable fast material then.
Reinforced principle of the present invention is that when feeder 13 was in the material feeding state, slurry sank in the aperture of feeder 13 rotors by the self gravitation effect.When 90 ° of the rotor rotation of feeder 13 were in the discharging state, the slurry in the aperture was gone out by solvent, and then brings polymeric kettle into by material.The aperture of feeder can be cylindrical, but preferably up big and down small taper shape can be beneficial to slurry like this and enter in the aperture.The feeder structure as shown in Figure 2, adopt an ordinary ball valve, vertical direction at the valve cross central line has two holes 16,17 again, the politef stopper 18 in different apertures beyond the Great Wall in the hole of the interior roating sphere of valve, the aperture of stopper 18 can be selected by promoter addition as requested, valve drives bead by a rotating cylinder 20 by a connecting axle 19 and does 90 ° of reciprocating motions, make it constantly to be in material feeding discharging state, the material feeding time of feeder is 1～15 minute, and discharging time is 2～30 seconds.In order to make catalyst near continuous charging as far as possible, the material feeding time can reach 0.5～1 minute.As requiring discontinuous feeding in raw material, the material feeding time can be set at infinity.
The present invention can realize the automatic continuous charging of slurry, and particularly micro-slurry is reinforced, and the reinforced time can arbitrarily be set as required, and I reaches per 30 seconds once, is similar to continuous charging.Maximum can reach infinity.The solid feeding quantity can reach 1～500g/h, and this invention not only can be used for continuous the feeding in raw material of catalyst in the propylene polymerization, also can be used for the reinforced of other pulverulent solids auxiliary agent, and the particle size range of powder can reach 10 μ～50 μ.
