Description
Technical field:
The present invention relates generally to the duplex surface modification field of ultra-fine non-metallic powder, relates in particular to a kind of superfine nonmetallic powder compound modified process equipment.
Technical background:
At present, ultra-fine non-metallic powder is as wide material sources, and is cheap, and material itself has advantages such as good rigidly, dimensional stability be good, has become the indispensable important source material of industrial circle such as plastics, rubber, coating.And processing fluidity is good, surface-active is high, with the good modified superfine non-metallic powder material of matrix material compatibility performance because of its excellent comprehensive performance, to have more and more wide development space, the modification technology of powder has become new material and has made one of the hot technology in field.Current, the special equipment that is applied to this property of powder surface seldom, most of powder surface modification equipment are quoted from industries such as chemical industry, plastics, pulverizing, and especially suitable high-performance surface modification equipment with micron, sub-micron and even nanometer grade powder material almost is blank.
There are two defectives technically in traditional non-metal powder body method (stirring the powder-modified mode of machine batch (-type) as height): the first, and production process is interrupted, and is difficult to realize extensive mechanization, automatic continuous production; The second, modifying process is simple, when above the modifier more than two kinds, is difficult to carry out accurate technology controlling and process, therefore can't carry out effective composite modified processing to ultra-fine non-metallic powder; The 3rd, dust pollution is serious in the production process.
Summary of the invention:
The objective of the invention is in order to remedy the deficiency of prior art, a kind of superfine nonmetallic powder compound modified process equipment is provided, have simple to operate, but computer programming, composite modified process and the composite modified equipment of ultra-fine non-metallic powder dry method that automatic control level is higher.
The present invention is achieved through the following technical solutions:
A kind of superfine nonmetallic powder compound modified process equipment, include a plurality of ultra-fine non-metal powder storage bin hoppers, described ultra-fine non-metal powder storage bin hopper discharge end is provided with pneumatic operated valve, described pneumatic operated valve lower end is provided with powder automatic gauge scale, it is characterized in that: described powder automatic gauge scale discharging opening is connected to the high-speed mixing machine inlet capable by pipeline transporter, be rotatablely equipped with the agitator arm of rotation at a high speed in the described high-speed mixer, the charging aperture of described high-speed mixer also is communicated with the modifier adding set, the discharging opening of described high-speed mixer is connected to the charging aperture of middle hopper by pipeline, the discharge end of described middle hopper is equipped with spiral metering batcher, described spiral metering batcher is connected to the feed end of three pulley type modifying machines by pipeline, described three roller modifying machines are modification cylinder and the feeding machine that isosceles triangle is arranged by three, air inlet, charging aperture, discharging opening is formed, the charging aperture of described three pulley type modifying machines also is communicated with the modifier adding set, the discharging opening of described three pulley type modifying machines is connected to the charging aperture of cyclone separator through piping, the discharging opening of described cyclone separator is transported to the charging aperture that is connected to the finished product feed bin through the gentle power conveying device of piping with powder, and the discharging opening of described finished product bin is connected in the automatic packaging machine by pipeline.
Described superfine nonmetallic powder compound modified process equipment is characterized in that: described modifier adding set is made up of a plurality of modifier holding vessels and modifier automatic gauge scale respectively.
Described superfine nonmetallic powder compound modified process equipment is characterized in that: described Pneumatic conveyer and pneumatic operated valve are automatic or manual.
What the main equipment of the composite modified equipment of dry method of described ultra-fine non-metal powder adopted is the composite modified unit that high low speed mixer and three roller modifying machines are together in series; By the totally-enclosed conveying device, self-measuring device etc. of configuration material, realize the closure of production process, the effusion of stopping dust; And utilize computer programming to realize that bulk modified unit and modified technique process PLC control automatically, realize the production process serialization.
The operation principle of described high-speed mixer mainly is that the agitator arm of at a high speed rotation makes material along the impeller tangential motion by the frictional force of surface and powder and side to the thrust of material, because being thrown to, the action of centrifugal force material gets back to the impeller center again after the inwall of deflection plate and mixing chamber rises to certain altitude simultaneously, and thrown, what so intersection was continuous flows, impel material evenly to disperse, the heat that strong self-friction produces impels modifier to be adsorbed on powder surface (ambient temperature can feed steam to chuck again when low and heat) fully, uniformly.When described three roller modifying machines are worked, the material for the treatment of modification feeds charging aperture through feeding machine, through with metering with after the surface modifier that feeds continuously contacts, successively by three columnar modification chambeies, remodeling the chamber in 3000 ~ 3500 rev/mins of high speed rotor rotated and stator and powder material intense impact, shearing and friction, force powder material loose and form the vortex two-phase flow, make surface modifier can be rapidly, equably with the powder granule surface action, form coating.
Connect by middle hopper and automatic gauge screw(-type) feeder between described high-speed mixer and the three roller continuous powdery surface modification machines, both can overcome high mixer is difficult to the following powder of modification micron and produces discontinuous, be difficult to accurately control the shortcoming of modified technique, can ideally realize again superfine powder is carried out the MULTIPLE COMPOSITE modification, contacting and purpose such as effect has equal opportunities, and modified effect is thorough of the good dispersion, powder that reaches powder and surface modifier and surface modifier.
Advantage of the present invention is:
The present invention has simple to operate, the modified effect excellence, and energy consumption of unit product and abrasion are low, performances such as no dust pollution, equipment operation simultaneously is continuous, easy, steady, automaticity is high.
