Growing along with science and technology, the application of composite is increasingly extensive, and machining composite material needs various fine powders to mix rear machine-shaping, because of particularity such as powder non-refractory, easy bonding, vulnerable to pollution, there is variety of issue in current mechanical agitation type mixed powder technology, the high temperature bonds that roll sex change, part of such as powder etc. are to produce a requisite important component part in the raw material processes such as composite and mix.
The uniformity that raw material mixes has very important impact to the quality of product, exists powder to mix uneven problem in Fine Chemical.Product processes raw material by Multicomponent phosphor composing, and the parameters such as the powder granule diameter of different components, proportion, density exist very big-difference, and this mixes a lot of problems of bringing just to many components powder.
The homogenizing of current domestic Fine Chemical to many components powder, mainly adopts mechanical agitation and fluidization formula to mix two kinds of modes.Limited by working condition, mechanical type mixes the shortcomings such as existence is easy pollutes, and local temperature is too high, efficiency is low, deposit dead angle, effect is general; And there is problems such as controlling difficulty, the easy segregation of powder, equipment complexity in fluidization formula.
Summary of the invention
The present invention is directed to that existing powder hybrid technology exists easily pollute, the problem such as efficiency is low, the powder pneumatic hybrid system of a kind of efficient homogenizing, many components powder good mixing effect is provided.
Powder pneumatic hybrid system of the present invention, is achieved through the following technical solutions:
This system, comprise blower fan, heat exchanger, refrigeration machine, filter, ribbon mixer and gas-solid separator, blower fan, heat exchanger, filter and ribbon mixer link together by pipeline successively, heat exchanger is connected with refrigeration machine, at least a set of metered charge device is set on the pipeline between filter and ribbon mixer, and gas-solid separator is connected to the end of ribbon mixer.
Gas-solid separator, comprise shell, top cover, impeller, rotating shaft, scraper and screen pack, the top of shell is provided with top cover, rotating shaft is installed in top cover, impeller and scraper are installed in rotating shaft, the side of top cover is provided with feed pipe and blast pipe, and outer casing bottom is provided with outlet, and screen pack is positioned at shell and is connected to the bottom of top cover.
Blower fan provides power (strength), and refrigeration machine ensures gas temperature, prevents temperatures involved powder characteristic, and filter ensures the degree of purity of gas, and powder is blown into ribbon mixer by gas after metered charge device enters diatom.Thread mixing pipe is without additionaling power device, blower fan provides and enters refrigeration machine after source of the gas and carry out cooling to gas, then enter filter cleaning, powder enters the pipeline between filter and helical pipe through metered charge device, together enter ribbon mixer through the high speed clean gas filtering, after the short time mixes, enter gas-solid separator, gas is separated and obtained powder mixture.
The present invention adopts gas to mix different powders, simple and compact for structure, easy to operate, stable working, and good mixing effect, efficiency are high, pollution-free, and reliability is high, is difficult for loss, and long service life is safe and reliable.

Detailed description of the invention
As shown in Figure 1, powder pneumatic hybrid system of the present invention mainly comprises blower fan 1, heat exchanger 3, refrigeration machine 4, filter 5, ribbon mixer 7 and gas-solid separator 8.Blower fan 1, heat exchanger 3, filter 5 and ribbon mixer 7 link together by pipeline successively, on the pipeline between blower fan 1 and heat exchanger 3, are provided with safety valve 2, to ensure that system air pressure is no more than setting value.Heat exchanger 3 is connected with refrigeration machine 4.On pipeline between filter 5 and ribbon mixer 7, be at least provided with a set of metered charge device (being provided with 3 covers in Fig. 1), the powder kind number that concrete quantity is mixed by needs determines.Gas-solid separator 8 is connected to the end of ribbon mixer 7.Blower fan 1 can adopt roots blower, mixes and transmitting power for powder mixes to provide.。Ribbon mixer 7 is, in a pipeline, helical form conduit is set, and pipe ends arranges charging aperture and discharging opening.Can vibratory sieve 9 be set at discharging opening place, the bottom of gas-solid separator 8.
The structure of gas-solid separator as shown in Figures 2 and 3, comprise shell 10, top cover 11, impeller 12, rotating shaft 13, scraper 14 and screen pack 15, the top of shell 10 is provided with top cover 11, in top cover 11, by bearing, rotating shaft 13 is installed, impeller 12 and scraper 14 are installed in rotating shaft 13, the side of top cover 11 is provided with feed pipe 16 and blast pipe 18(referring to Fig. 3), the bottom of shell 10 is mixed powder outlet, is also provided with fixed mount 17 on shell 10.Screen pack 15 is positioned at shell 10 and is connected to the bottom of top cover 11.Scraper 14 is positioned at screen pack 15, for wiping powder mixture residual on screen pack 15 off.Impeller 12 is rotated by the gas-powered entering in shell 10, without additionaling power, has ensured the degree of purity of powder.
Due to air temperature rise after blower fan 1 boosts, it is unfavorable that powder is mixed, and after heat exchanger 3 and refrigeration machine 4 coolings, makes gas temperature reach mixing requirement.A small amount of moisture and wet goods impurity after filter 5 is removed temperature reduction in Compressed Gas, to ensure the cleanliness factor of gas.Powder to be mixed adds pipeline in proportion through each metered charge device, under strength promotes, enters ribbon mixer 7 and mixes, and mixed material enters gas-solid separator 8 and carries out separating of powder and gas.Gas and powders mixture are first in feed pipe 19 enters top cover 11, blowing impeller 12 rotates, impeller 12 drives rotating shaft 13 to rotate, and then drive scraper 14 to rotate, gas is drained through blast pipe 24, ensure effectively to filter, powder mixture filters through filter screen 15, enters vibratory sieve 9 by the bottom outlet of shell 10.Scraper 14 is wiped powder mixture residual on screen pack 15 off.
The present invention has following characteristics:
