Abstract
The utility model discloses a static separator of a medium-speed mill. The static separator comprises a shell (1), a powder return cone (2), blades (3), a blade adjustment mechanism (4), a powder outlet pipe (5) welded on a separator cover, and auxiliary guide rib leaves (6) welded on the outer cylindrical surface of the powder outlet pipe (5). By forming a certain included angle between the blades and a rotating shaft and adding the auxiliary guide rib leaves on the outer cylindrical surface of the powder outlet pipe, the running path and the moving direction of material dust after entering the static separator are changed, and thereby the separating effect of the separator is improved, and the fineness of powder is improved.
Description
Technical field
The utility model relates to the quiet separator of a kind of medium speed mill.
Background technology
The quiet separator of medium speed mill is for separating of after grinding in medium speed mill, the material dust that wind of quilt high speed is sent here, by modes such as collision, change material movement directions, again grinding is separated and returned to undesirable bulky grain, only allow satisfactory fine powder pass through.The quiet cyclone separator arrangement of medium speed mill is simple, seal simple and reliable, need not sealing air and extra energy consumption, certain regulating power arranged, therefore be widely used in thermal power plant's coal pulverizer, but because existing quiet separator separating effect is undesirable, it is thicker to go out powder fineness, is unfavorable for burning and energy-conserving and environment-protective, along with the raising of energy-conserving and environment-protective requirement and the increase of thermal power generation unit, higher to the fineness of pulverized coal requirement, the use of quiet separator is restricted.
The quiet separator of existing medium speed mill, some blades vertically are distributed on the separator circumference, blade plane all points to the separator center, blade can be around vertical rotation axis in certain angle scope inter-sync horizontal deflection, material dust enters separator from the blade by deflection radially, change the direction of motion with the blade collision with by blade, turn and progress into flour extraction pipe at the plane internal rotation perpendicular to separator axle center line, on the flour extraction pipe external cylindrical surface, assist in addition the guiding rib leaf, causing like this material dust to enter before the flour extraction pipe the short and direction of motion of operating path changes little, therefore separating effect is not good, and powder delivery is thicker.
The utility model content
The purpose of this utility model provides a kind of quiet separator, by the arrangement form that changes the separator blade and the auxiliary guiding rib leaf that increases the flour extraction pipe external cylindrical surface, change operating path and the direction of motion of material dust, thereby improve separating effect, obtain the thinner powder fineness that goes out.
In order to solve the problems of the technologies described above, the utility model adopts following technical scheme: the quiet separator of a kind of medium speed mill, comprise housing (1), return powder cone (2), blade (3), blade turning mechanism (4), be welded on the flour extraction pipe (5) on the cyclone cover and be welded in the auxiliary guiding rib leaf (6) of flour extraction pipe (5) external cylindrical surface, it is characterized in that: some separator blades (3) tilt to be distributed on the separator circumference, blade plane and vertical rotation axis axial line slanted angle α, α gets between 10 °～40 °, blade (3) can be around vertical rotation axis in certain angle scope inter-sync horizontal deflection, on the flour extraction pipe external cylindrical surface, weld some being evenly arranged and the auxiliary guiding rib leaf (6) consistent with corresponding blade lean simultaneously.
The blade (3) and the auxiliary guiding rib leaf (6) consistent with blade lean that tilt, purpose is after making material dust pass through blade (3) to enter separator, produce a synthetic screw that horizontally rotates with the axis downward direction, make the effect of the existing radial separation of blade, the effect that axial separation is arranged again, the while material dust changes into upwards by downward screw, and screw enters flour extraction pipe (5), both increased the length of operating path, the material movement direction changes also very greatly, meal will obtain effective separation because inertia is difficult to greatly break-in.

Wherein, Reference numeral: 1 is shell separator, and 2 for separator returns the powder cone, and 3 is the separator blade, and 4 is blade turning mechanism, and 5 is flour extraction pipe, and 6 are auxiliary guiding rib leaf, and 7 is the material operating path.
The specific embodiment
Such as Fig. 1, Fig. 2 and shown in Figure 3, common quiet separator comprises housing (1), return powder cone (2), blade (3), blade turning mechanism (4), be welded on the flour extraction pipe (5) on the cyclone cover, separator blade (3) vertically is distributed on the separator circumference, blade plane all points to the separator center, blade (3) can be around vertical rotation axis in certain angle scope inter-sync horizontal deflection, by blade turning mechanism (4) adjusting vane (3) X deflection angle, material dust is by behind the blade (3), rotation and progress into flour extraction pipe (5) in perpendicular to the horizontal plane of separator axle center line, isolated coarse granule returns the continuation grinding from returning powder cone (2), the front operating path of flour extraction pipe (5) is lacked and the direction of motion changes little because material dust enters, therefore separating effect is not good, and powder delivery is thicker.
Such as Fig. 4, Fig. 5 and shown in Figure 6, the quiet separator of the utility model comprises housing (1), return powder cone (2), blade (3), blade turning mechanism (4), be welded on flour extraction pipe (5) and auxiliary guiding rib leaf (6) on the cyclone cover, separator blade (3) tilts to be distributed on the separator circumference, blade plane and vertical rotation axis axial line slanted angle α, α gets between 10 °～40 °, blade (3) can be around vertical rotation axis in certain angle scope inter-sync horizontal deflection, on flour extraction pipe (5) external cylindrical surface, weld some being evenly arranged and the auxiliary guiding rib leaf (6) consistent with corresponding blade (3) inclination, by blade turning mechanism (4) adjusting vane (3) X deflection angle, when material dust enters separator and under the effect of auxiliary guiding rib leaf (6) by blade (3), a synthetic screw that horizontally rotates with the axis downward direction will be produced, make the effect of the existing radial separation of blade (3), the effect that axial separation is arranged again, the while material dust changes into upwards by downward screw, and screw enters flour extraction pipe (5), both increased the length of operating path, the material movement direction changes also very large, meal is because inertia is difficult to greatly break-in, to obtain effective separation, isolated coarse granule returns the continuation grinding from returning powder cone (2).
The above only is preferred embodiment of the present utility model; not in order to limit the utility model; all any modifications of within spirit of the present utility model and principle, doing, be equal to and replace and improvement etc., all should be included within the protection domain of the present utility model.
