Description
Technical field
The utility model relates to a kind of centrifuge, specifically a kind of horizontal decanter centrifuge.
Background technology
The suspension of sedimentation centrifuge to solid particle concentrates, dewater or classification be separated time, rotary drum usually can operationally High Rotation Speed, because drum inner wall of the prior art is general comparatively smooth, in high-speed rotation material easily and rotatory drum wall skid, cause separation discharging effect not ideal enough, and due to pug and drum inner wall generation Relative friction, so very easily cause wearing and tearing to rotatory drum wall, thus rotatory drum wall is damaged, to such an extent as to reduce serviceability and the service life of equipment; Some material usually can carry a small amount of volatility and to harden solvent, when Separation of Solid and Liquid, the volatile one-tenth gaseous state of these reaction dissolvents, has corrosiveness to equipment itself, and reaction dissolvent is all combustibles, in centrifuge runs up process, easily produce spark, cause the generation of peril; For above problem, need to improve the centrifuge of prior art.
Utility model content
The purpose of this utility model is to provide a kind of vapor reaction solvent of avoiding to the corrosion of rotary drum, increase the frictional force between material and rotary drum, reduce material to the damage of rotary drum, effective stroke of raising solid-liquid material handling and the horizontal decanter centrifuge of speed, to solve the problem proposed in above-mentioned background technology.
For achieving the above object, the utility model provides following technical scheme:
A kind of horizontal decanter centrifuge, comprise rotary drum, pusher and exhaust apparatus, described rotary drum comprises conical section and direct tube section, conical section and direct tube section intersection are provided with bolt holder, bolt holder is bolted, described drum inner wall is welded with protection muscle along its length, and the protection muscle bulging circumferencial direction that rotates is uniformly distributed, and forms an isolation channel between adjacent two protection muscles and drum inner wall; It is interior and coaxial with rotary drum that described pusher is arranged on rotary drum, and described pusher is double threaded screw structure, and its screw body is with double end involute helical blade, and longitudinal periphery top surfacing of described double end involute helical blade has wear-resistant material layer; Be provided with housing outside described rotary drum, housing is provided with steam vent, and steam vent is connected with discharge duct.
As further program of the utility model: described protection muscle adopts carbide alloy material to make, protection muscle is set to six.
As the utility model further scheme: described rotary drum and pusher drive by motor, and rotary drum is identical with the rotation direction of pusher.
As the utility model further scheme: described motor is connected with differential mechanism.
As the utility model further scheme: described wear-resistant material layer is tungsten carbide material.
Compared with prior art, the beneficial effects of the utility model are: the utility model arranges steam vent on rotary drum housing, steam vent connects discharge duct, like this, centrifuge in the running, vapor reaction solvent is discharged by discharge duct, avoids the corrosion of vapor reaction solvent to rotary drum, effectively prevent the generation of potential safety hazard simultaneously; Owing to being provided with protection muscle at drum inner wall, can make rotary drum in rotary course, material is connected in the isolation channel of protection muscle formation, material in drum rotating process in isolation channel is rotated and forms one deck overcoat, because in overcoat, material surface is rough so therefore the frictional force frictional force be greater than between rotatory drum wall and material between overcoat and material avoid material to skid, and due to overcoat effect thus alleviate the wearing and tearing of material to drum inner wall, the service life of extension device; By being provided with the pusher of double end involute helical blade in rotary drum with one heart, effectively improve stroke and the speed of solid-liquid material handling, improving the separation capacity of equipment.In addition, because surfacing has wear-resistant material layer on double end involute helical blade, improve the anti-wear performance of double end involute helical blade, reduce part replacement frequency, save production cost.
