Description
Technical field
The present invention relates to wettable powder preparation field, specifically a kind of wettable powder mixer.
Background technology
Mixer is the plant equipment for uniformly mixing two or more material using mechanical force and gravity etc..
During mixing, material contact surface area can also be increased, to promote to chemically react;Physical change can also be accelerated.
Conventional mixer is divided into gas and low-viscosity (mobile) liquid mixer, medium-high viscosity liquid and paste mixer, powder
Shape and the major class of particulate solid material mixing machinery four.
The formulations of pesticide mainly include pulvis, wettable powder, emulsifying agent, missible oil, suspending agent, granula, aqua etc., in China
Most active compounds, which are processed, is prepared into wettable powder and missible oil both formulations, and wherein wettable is due to its preservation, transport
It is convenient, it is a kind of formulations of pesticide of new stabilization.Preparation process is：After pesticide original medicine and filler, auxiliary agent are mixed in proportion
Crushing reaches 98% and crosses 325 mesh sieves, therefore it is required that the particle diameter of wettable powder is less than 44 microns, average grain diameter is 25 microns.Make
During, wettable powder plus water are made into stable suspending agent, used using atomizers spray.
Wettable powder there are problems that when in use in the prior art：Size distribution is uneven, and granular size is uneven, leads
The suspending agent performance of cause configuration is unstable, phenomena such as precipitation, suspension, layering easily occurs；Therefore in the mixed process of material
It is uniformly sufficiently well mixed so that the particle finally crushed is uniform.Mixed in mixed process using mixer, prior art
In mixer mainly include V-Mixer, double-spiral conical mixer, three-dimensional mixer, Horizontal type helical ribbon mixer.Wherein exist
The material mixing in the fields such as chemical industry, medicine, agricultural chemicals selects Horizontal type helical ribbon mixer, and cost is low, mixing velocity is fast, effect is good.
Existing material mixer there are problems that in the raw material mixing as wettable powder：1st, existing spiral shell
Band mixing velocity is slow, and when mixing wettable powder, due to raw material mixing heat release, exothermic process causes to lump, and have impact on material
Performance, while the material after luming have impact on the particle size distribution of follow-up wettable powder, 2, material be easily adsorbed onto it is mixed
On the cell wall for closing groove, mixing efficiency is influenceed, while the material mixing adhered to is uneven；Therefore need quickly mixing and reduce former
Lumpd caused by material mixing heat release.

The rotor motion of opposite direction motion, carries out compound motion, and double-shaft paddle drives material to be done along trough inwall along inverse two
Hour hands are rotated, and axle center rotation is done close to material at axle center, are axially promoted by interior to both sides, external spiral drives to be done close to barrel material
Axle center rotates, and axially by both sides to interior promotion, then causes convection circulation in material barrel body, shearing infiltration, complete material compared with
Quick uniform mixes in short time.
Further, the side wall of the scraper plate is provided with irregular or regular projection.Projection in scraper plate side wall can have
Material of the blade coating absorption on U-type groove cell wall of effect, realize it is significantly more efficient scrape material, while play and certain shear, mix
The effect of compound material.
Further, the hollow pipe is provided with cooling liquid inlet, is threadedly coupled feed tube on the cooling liquid inlet, institute
State feed tube and be provided with sealing valve, the cooling tube passes through agitating shaft.The cooling liquid inlet that hollow pipe is provided with can realize replacing
Coolant.
Operation principle：Using conveying worm from the charging aperture feeding at the top of mixer, feeding speed is fast, completes mixing
Afterwards, U-shaped mixing channel is overturn, material is poured out, discharging speed is fast, time saving and energy saving.After feeding, the motor of agitating shaft is opened, is stirred
Axle drives ribbon flight agitating paddle to rotate, and material is sheared, mix, disperseed, realizes the mixing to material, while scraper plate has
Effect scrapes the material being adsorbed onto on the cell wall of U-type groove, while realize and material of the U-type groove on cell wall is mixed,
Scattered, shearing, realization fast and effectively mix；Hollow pipe is provided with agitating shaft, coolant is provided with hollow pipe, realizes to stirring
Mix the cooling of axle, and then realize the cooling to material, avoid at the center of material that temperature is too high to be caused to lump, reduce material and stirring
Mix the blocking phenomenon of aggregation on axle so that material is finally well mixed, and whole mixed process temperature becomes big less, whole material
The temperature difference is less, and material is uniform, is not susceptible to thermally decompose.
The present invention compared with prior art, has the advantages that：1st, the shearing to material, mixing speed are fast, mixing
Uniformly；2nd, the present invention is realized to effectively being cooled down at the center of material, is reduced the fever phenomenon in material mixed process, is avoided material
