Description

Attapulgite clay pulping process and device thereof

The present invention relates to a kind of method and crystals of clay dispersal device thereof, specifically a kind of attapulgite clay pulping process and device thereof with mineral clay slurrying.

Attapulgite clay slurrying generally has glue mill process, extrusion process and homogenate technology, these technologies are except that the specific equipment of needs, dry run is generally all arranged, energy resource consumption is big, (seeing " nonmetallic ore " magazine second phase in 1989 the 45th page of " utilizing machining to improve attapulgite clay pulping performance " literary composition); CN88102788A discloses a kind of modulator approach of attapulgite clay printing and dyeing slurry, its pulping technology also is traditional method, earlier slurry attapulgite clay crushing raw ore is to diameter below 2 millimeters, behind the water logging bubble, be dispersed into paste with the grinder extruding, put to smash and add water in the pulp grinder and stir into ore pulp, wet concentration again, behind plate compression by high pressure homogenizer homogenate slurry, long flow path, complex process; US3509066, US3596760 propose to choose the attapulgite clay particulate to reach certain solid content in magnesium oxide aqueous solution with tetrasodium pyrophosphate.

The objective of the invention is under the prerequisite that guarantees the attapulgite clay stock quality, to simplify pulping process, and designed special dispersal device for this reason, to adapt to every field such as light industry, weaving, life be daily more and more widely to the needs of this slurry.

Technology of the present invention is, the commodity Concave-convex clay rod powder of directly pulverizing is dropped in the fermentation vat, normal temperature soaks down and is no less than 20 minutes, the control amount of water makes its solid content be not more than the 7%(percentage by weight, down together) so that pass through screen cloth, cross 200 eye mesh screens then and inject sedimentation in the pond, take out supernatant liquor after the sedimentation fully, the control solid content is no less than at 9% o'clock and inserts in the dispersion slot, in normal temperature, normal pressure starts the crystal disperser down, makes attapulgite ore magma under the forceful action of crystal disperser, adds modifier at last to stir, make the attapulgite clay slurry, modifier also can make preceding adding in magma.According to adding different modifier, obtained attapulgite clay slurry can be used for production fields such as daily-use chemical industry, textile printing and dyeing.Thickener in washing agent, the textile printing mill base etc. for example.Modifier can be carbonate, sulfate, polyvinyl alcohol, carboxymethyl cellulose, glycerine etc.As add two or morely, its ratio can be controlled total amount arbitrarily in the 0.1%-4.0%(weight ratio).This technological process is short, equipment is simple, fermentation vat, settling tank, dispersion slot can be made by metal, plastics or common building material, as long as the settling tank of sufficient amount is arranged, just can produce continuously, prepared gum size is fine and smooth lubricated, has good thixotropy, rheological characteristic, chemical compatibility and advantages of higher stability.

Why flow process is short in the present invention, and key is the powerful dispersal device of smart design.Dispersal device is made up of dispersion slot and powerful disperser; Its cross section of dispersion slot can be circular, oval or anticipate as shown in Figure 1 that we are referred to as heart etc., and are uncovered, flat or non-flat, puts powerful disperser on it; Powerful disperser is made of support, motor, main shaft and combined type profile of tooth leaf slurry, as accompanying drawing 2, be that the main shaft upper end is with the fixing two-layer at least combined type profile of tooth leaf slurry in the bottom of motor connection, main shaft, at least two every layer, balance or symmetrical distribution, combined type profile of tooth leaf oar is to be made by metal or non-metal plate, meets shear direction and makes profile of tooth, and profile of tooth can be a zigzag; As accompanying drawing 3, what leaf was starched goes up or lower surface, and perhaps upper and lower surface is inlayed some toothed rack such as accompanying drawing 4 simultaneously, so that from multi-faceted reinforcement crystal molecule peptizaiton; The rotary speed of leaf slurry is determined that by main shaft the Revolution Per Minute of main shaft is no less than 1400 to be changeed.Apparatus of the present invention when work, earlier with commodity attapulgite clay powder through soaking, sieve, injecting dispersion slot after the sedimentation, take turns starting the powerful disperser of motor drives and do to rotate at a high speed, motor speed can be controlled at per minute 2000 right side of turning left with electronic installation.When the leaf oar when attapulgite clay suspension high speed turns round, the attapulgite clay of shape groove inner suspension is subjected to the compound tooth-shaped leaf of multi-level multi-faceted arrangement and starches strong shearing force effect, fine and close attapulgite clay crystal molecule fibrous agrregate is torn dispersion; Along with the running continuously of leaf slurry, several strands of macrofluids that form in the shape groove impact mutually consumingly, the baffle plate of groove inwall is excited into numerous micro cyclones after again the macrofluid of strenuous exercise being cut apart, increase severely by force so microturbulence swashs, aggravated the macroscopic view in the shape groove, the interface impact and the friction of microfluid.Simultaneously, the liquid stream that zigzag leaf slurry constantly circulates to week applies strong shear force, and the decentralization of attapulgite clay crystal molecule reticular fibre aggregate is along with the disperser corresponding raising of prolongation of the duration of runs.

Advantage of the present invention is to have simplified the traditional processing technology of attapulgite clay slurry greatly, and not only equipment is few, and technology is easy, and is to operate at normal temperatures and pressures, small investment, and energy consumption is little, and equipment is easily processed, easy control of technology conditions.In addition, the processing that is not only applicable to attapulgite clay of this dispersal device also is applicable to Dispersion of Clay processing such as bentonite, kaolin.
