Abstract
The invention discloses a horizontal type spiral unloading sedimentation centrifuge with protective partitioning ribs. The centrifuge comprises a rotating drum for dehydrating sludge and a driving device for driving the rotating drum to rotate, wherein a friction surface is arranged on the inner wall of the rotating drum; the friction surface is used for driving the sludge to rotate along with the rotating drum; a plurality of protective partitioning ribs are arranged on the friction surface in a protruding manner; partitioning grooves are formed between each two adjacent protective partitioning ribs. When the driving device drives the rotating drum to rotate, each partitioning groove is filled with a protective sludge layer for separating the friction surface from external sludge; as the partitioning grooves are formed, the friction between the sludge and the rotating drum is increased, and the damage of the sludge to the rotating drum is reduced.
Description
Technical field
The present invention relates to a kind of horizontal spiral discharge sedimentation centrifuge that is provided with protection muscle.
Background technology
The horizontal spiral discharge sedimentation centrifuge that is provided with protection muscle often using in environmental protection and chemical industry at present, can concentrate the suspension of solid particle, dehydration or classification are separated, the rotary drum of this centrifuge is meeting High Rotation Speed when operation conventionally, because drum inner wall of the prior art is generally comparatively smooth, in High Rotation Speed process pug easily and rotatory drum wall skid, cause separated discharging effect not ideal enough, and because pug produces relative friction with drum inner wall, so rotatory drum wall is very easily caused to wearing and tearing, thereby rotatory drum wall is damaged, to such an extent as to serviceability and the service life of having reduced equipment.
Summary of the invention
The object of the invention is to overcome the defect of prior art, a kind of horizontal screw centrifuge is provided.
For achieving the above object, the present invention adopts a kind of horizontal spiral discharge sedimentation centrifuge that is provided with protection muscle, comprise the rotary drum that mud is dewatered and the drive unit that drives rotary drum to rotate, the inwall of described rotary drum is provided with rubbing surface, rubbing surface drives mud to rotate with rotary drum, wherein, on described rubbing surface, convex with some protection muscles, between adjacent protection muscle, form isolation channel, when described drive unit starts rotary drum rotation, in isolation channel, be filled with the protection sludge blanket of rubbing surface and the isolation of outside mud.
Owing to being provided with protection muscle at drum inner wall, can make rotary drum in rotary course, pug is connected in the isolation channel of protection muscle formation, make the pug in isolation channel in drum rotating process rotate to form one deck protection sludge blanket, because so therefore the frictional force that the frictional force between pug surface in protection sludge blanket rough protection sludge blanket and pug is greater than between rotatory drum wall and pug avoid pug to skid, and because thereby the effect of protection sludge blanket has alleviated pug to the wearing and tearing to drum inner wall, the service life of extension device
Wherein, described rotary drum comprises conical section and direct tube section, and described conical section and direct tube section junction are bolted, and on the termination of described conical section, offer charging aperture.
Wherein, the thickness of described protection muscle is 2-3mm.If the blocked up separation of not only wasting material and affecting pug of thickness through experiment protection muscle.
Wherein, the width of described protection muscle is 12-14mm.If the wide separation of not only wasting material and affecting pug of width through experiment protection muscle
Wherein, described protection muscle adopts carbide alloy and rotatory drum wall welding.Adopting carbide alloy is to consider that the wearability of carbide alloy is better.
Wherein, the protection muscle in described direct tube section is arranged in direct tube section along the axial direction of rotating cylinder.
Accompanying drawing explanation
The structural representation of Fig. 1, embodiment of the present invention product;
Fig. 2 is the sectional view of the direct tube section of rotary drum.
The specific embodiment
Refer to Fig. 1-2, the present invention relates to a kind of horizontal screw centrifuge, this centrifuge comprises the rotary drum 1 of a rotation, and the drive unit that drives rotary drum 1 rotation, rotary drum comprises conical section 11 and direct tube section 12, conical section 11 is provided with bolt holder with direct tube section 12 junctions, bolt holder is fixing by bolt 6, on the termination of conical section 11, offer charging aperture 2, pug enters in rotary drum 1 from charging aperture 2, rotary drum 1 inwall be provided with pug between the rubbing surface contacting 7, on the inwall of conical section 11 and direct tube section 12, be welded with the protection muscle 3 of carbide alloy material, every 3 muscle, the axial direction along rotating cylinder 1 is arranged in direct tube section 12 in protection in direct tube section 12, protection muscle 3 in conical section 11 is connected with the protection muscle 3 in direct tube section 12, the quantity of protection muscle 3 is some, the quantity of protection muscle 3 is determined according to the large ting model of rotary drum, between adjacent two protection muscles 3 and rotatory drum wall, form an isolation channel 4, when pug enters rotary drum 1 and is rotated, pug enters after isolation channel 4, between pug in isolation channel 4 and rotary drum 1, be relative static, thereby upper surface forms a protection sludge blanket, this protection sludge blanket has replaced rotatory drum wall directly to contact with pug, so the lower surface of protection sludge blanket is because the effect stopping due to protection muscle 3 is relative static with rotatory drum wall, therefore can not cause too much friction to rotatory drum wall, the upper surface of protection sludge blanket directly contacts and rubs with pug, thereby the irregularly shaped frictional force that can increase of pug prevents that pug from skidding, and protection sludge blanket upper surface has replaced rotatory drum wall and pug friction, thereby reduced the infringement to rotatory drum wall, the thickness of protection muscle 3 is made as 2-3mm, and the width of protection muscle is that 12-14mm is the optimal selection drawing according to test of many times.
