Description
Technical field
The utility model relates to two-dimensional motion mixer technical field, is specifically the dustproof flange of a kind of rotation for two-dimensional motion mixer.
Background technique
Two-dimensional motion mixer can be used for the raw material mixed processes of a lot of industries, and material enters from material feeding mouth, through rotation and the swing of mixing machine, after material is evenly mixed, flows to discharge port, then flows into storage-bag or holding vessel from discharge port.
In the production process of advanced ceramics, need the raw material that sphere diameter is less than to 1um to be mixed to form slurry, after the microsphere particle that the spray-dried one-tenth particle diameter of slurry is 20-200um, can not use immediately.For ensureing the homogeneity of rear road moulding, need powder be pressed to particle size classification through sub-sieve, then join level according to need of production by particle diameter and mix a homogenizing.
Advanced ceramics is a kind of to the exigent structural material of material purity, and a little impurity can cause material pore or defects i.e.cracks, or even fatal defect.Because raw material powder is sub-micro level, be easy to fly upward, because sealing is very important in homogenization process, the advanced ceramics leaking for the health of human body again considerable influence two-dimensional motion mixer be the equipment that powder is joined grade homogenizing, in work, staving rotates and swings, and discharge end need and be flexible coupling to ensure that with rotary flange powder flows out.General rotary flange adopts and is slidably connected, without dust guard, dumb, the powder wearing and tearing of easily being flown upward and stuck, and in environment, dust is also easily sneaked in raw material, and such device had both polluted production environment, also can bring hidden danger to material.
Model utility content
Technical problem to be solved in the utility model is, provide a kind of good dustproof effect, flexibly, not easy to wear and stuck, reduce the dustproof flange of the rotation for two-dimensional motion mixer of the impact on polluting production environment and the hidden danger to material.
Technological scheme to be solved in the utility model is, a kind of dustproof flange of the rotation for two-dimensional motion mixer with following structure providing, it comprises overcoat, bearing cap, bearing and axle sleeve, described bearing cap is located at outside axle sleeve, the outer wall close-fitting of the inner ring of described bearing and axle sleeve, the inwall close-fitting of the outer ring of described bearing and bearing cap, outside described, be set in one end of bearing cap and be located at outside axle sleeve, the removable positioning block that is connected with of the other end of described bearing cap, described positioning block is located at outside axle sleeve, the two ends of described bearing are respectively equipped with an outside framework oil seal being socketed in outside axle sleeve, between described axle sleeve and overcoat, be provided with a mechanical seal device.
Described mechanical seal device comprises the stationary ring and the rotating ring that are located at outside axle sleeve, between the inwall of described stationary ring and the outer wall of axle sleeve, be provided with gap, the outer wall of described stationary ring and outer casing inner wall are fixed and are sealed, the seal face of described stationary ring and the seal face of rotating ring are close to, described rotating ring and axle sleeve be spacing and sealing circumferentially, between the interior step surface of the interior edge face of described rotating ring and axle sleeve, is provided with wavy spring.
This end axle sleeve that positioning block is installed is also provided with retention mechanism outward.
Adopt after above structure, the utility model compared with prior art, has the following advantages: this device is arranged on two-dimensional motion mixer discharge port, can relatively rotate with discharge port.In the time that mixing machine is worked, discharge port rotates with mixing machine and swings up and down, and rotates dustproof flange and is flexible coupling and do not rotate.When mixing machine work, the powder having mixed, by discharge port, through over-rotation dust preventing method orchid, flows in storage facility by being flexible coupling.In the dustproof flange of rotation, there is stationary ring to coordinate ring to prevent mixed powder effusion with rotating ring, cause waste and befouling environment, also prevent that in environment, impurity enters in raw material, outside framework oil seal can prevent that bearing is stuck by powder wearing and tearing simultaneously, also can prevent that bearing lubrication liquid from entering in raw material.This device is suitable for advanced ceramics spray drying powder and mixes demand, good dustproof effect, flexibly, not easy to wear and stuck, reduce polluting the impact of production environment and the hidden danger to material.
As improvement, described mechanical seal device comprises the stationary ring and the rotating ring that are located at outside axle sleeve, between the inwall of described stationary ring and the outer wall of axle sleeve, be provided with gap, the outer wall of described stationary ring and outer casing inner wall are fixed and are sealed, the seal face of described stationary ring and the seal face of rotating ring are close to, described rotating ring and axle sleeve be spacing and sealing circumferentially, and this construction machine sealing device structure is simple, and good sealing effect, reliability are high.
