Abstract
The utility model discloses an efficient wear resistant cyclone dust collector, which is suitable for dusting of boilers and reclamation of power materials in the fields of food, fodder and industrial fields of chemical industry, metallurgy, etc. The utility model is mainly characterized in that a dust hopper is composed of a dust collecting barrel, a base board and a pin shaft, which causes separated dust to be on the side of the base board of the dust hopper near the barrel wall under the function of centrifugal force and inertial force, avoiding central zone of negative pressure and secondary dust blowing; an inner separation barrel is arranged between an outer separation barrel and an exhaust pipe; accelerating airflow is guided in the upper end of the inner separation barrel; the accelerating airflow is used for improving dedusting efficiency and preventing sticky dust from sticking to walls; the materials of wearing parts of the dust collector are iron plates with porcelain enamel on the surface, enhancing the wear resistant performance of the dust collector.
Description
The utility model belongs to cyclone dust removal equipment, is applicable to the recovery of industrial circle powder materials such as boiler dusting and food, feed, chemical industry, metallurgy.
The pattern of cyclone dust collectors is a lot, and cylindrical shape is arranged, taper barrel, divergent contour and cyclone shape etc.Their common feature is the lower end that dust-exhausting port places the dust hopper center.Test shows, the negative pressure of dust hopper center is bigger, and the particle dust at dust-exhausting port place is easy to be inhaled into negative pressuren zone (reentrainment of dust), and enters atmosphere with ascending air, and efficiency of dust collection is descended.The cylindrical shape cylinder can avoid taper barrel cylinder or divergent contour cylinder because of change local eddy currents and dust back-mixing that barrel dliameter produced, but because the linear loss of flowed energy also can cause efficiency of dust collection to descend and the sticking wall of sticky dust.
The purpose of this utility model provides a kind of high-efficiency abrasion-proof cyclone dust collectors.Form dust hopper by control of dust tube, base plate and bearing pin, make isolated dust under the effect of centrifugal force and inertia force, drop on the nearly barrel side of dust hopper base plate, avoided the central negative nip, avoided reentrainment of dust.Between cylinder and the blast pipe, interior cylinder is installed outside, and imports the acceleration air-flow, utilize the acceleration air-flow to improve efficiency of dust collection, reduce energy loss and prevent that sticky dust from gluing wall in interior cylinder upper end.The material of deduster easy-abrasion part is the iron plate of surperficial enamel, has improved the wear-resistant and anti-adhesion performance of deduster greatly.
The technical solution of the utility model is achieved in that dust-containing air stream cylinder outside the dust-contained airflow inlet tangentially is sucked into, and turns to eddy flow outside the formation down at the dust-containing air stream extruding backspin that enters subsequently; Under action of centrifugal force, dust passes the outside cylinder motion in outer eddy flow district, rotatablely moves to the bottom of outer cylinder in barrel place deposition and with outer eddy flow; Isolated dust under centrifugal force and inertia force effect, from radiation shield and outside gap between the cylinder inject the control of dust tube, in the nearly barrel side deposition of base plate; Dust-removing gas stream, forms the center eddy flow that moves upward and enters atmosphere to center flow along the radiation shield upper surface under the suction function of center; The acceleration air-flow that interior cylinder imports, quicken the rotation of center eddy flow on the one hand, make the particle dust centrifugation once more in eddy flow district, center, and isolated dust is brought into outer eddy flow district, externally eddy flow tangentially quickens on the other hand, improves the separating effect of particle dust and prevents that sticky dust from gluing wall; Dust hopper is for lifting end formula dust outlet geometry, and base plate contacts with the control of dust tube is airtight during dedusting, opens base plate during dust discharge, makes dust fall discharge; Blast pipe, interior cylinder, quicken air flow inlet, separate outward, the material of easy-abrasion parts such as dust-contained airflow inlet and radiation shield is the iron plate of surperficial enamel, can improve the wear-resistant and anti-adhesion performance of deduster, reduces material and processing cost, improves service life.
High-efficiency abrasion-proof cyclone dust collectors efficiency of dust collection height, production cost is low, anti-wear performance good, long service life, applied range, has vast market.
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.
Fig. 1 is a schematic diagram of the present utility model.
As shown in the figure, the utility model structurally is made up of blast pipe (1), interior cylinder (2), acceleration air flow inlet (3), outer cylinder (4), dust-contained airflow inlet (5), radiation shield (6), control of dust tube (7), bearing pin (8) and base plate parts such as (9).
In the cylinder (2), top and air-introduced machine linked in blast pipe (1) inserted, under the effect of air inducing negative pressure, with the dust-removing gas stream sucking-off in center eddy flow district.
Interior cylinder (2) is positioned between outer cylinder (4) and the blast pipe (1), be cylindrical shape, there is the acceleration air flow inlet of tangential connection the upper end, its effect is to import to quicken air-flow, particle dust to center eddy flow district separates once more, externally eddy flow tangentially quickens, and quickens dust separation, prevents that sticky dust from gluing wall.
Outer cylinder (4) is a cylindrical shape, and dust-contained airflow forms outer eddy flow within it and carries out the solid and gas separation.It columnar structured can be eliminated taper barrel and divergent contour cyclone separating tube effectively because of becoming local eddy currents and the reentrainment of dust that barrel dliameter causes.
Radiation shield (6) is a tapered tube, and isolated dust is injected in the control of dust tube (7) along the radiation shield (6) and the gap of outer cylinder (4) according to inertia from dust-contained airflow, and dust-removing gas flows and moves upward along radiation shield (6) upper surface, becomes the center eddy flow.
Control of dust tube (7), bearing pin (8) and base plate (9) are formed dust hopper.Base plate during dedusting (9) and airtight contact of control of dust tube (7), isolated dust deposit is in the nearly barrel side of base plate (9); Open base plate during dust discharge, dust falls discharge.
The material of blast pipe (1), interior cylinder (2), acceleration air flow inlet (3), outer cylinder (4), dust-contained airflow inlet (5), radiation shield easy-abrasion parts such as (6) is the iron plate of surperficial enamel.
During work, dust-containing air stream is cylinder (4) outside dust-contained airflow inlet (5) tangentially is sucked into, and turns to eddy flow outside the formation down at the dust-containing air stream extruding backspin that enters subsequently; Under action of centrifugal force, dust passes the outside cylinder in outer eddy flow district (4) motion, rotatablely moves to the bottom of outer cylinder (4) in barrel place deposition and with outer eddy flow; Isolated dust under centrifugal force and inertia force effect, from radiation shield (6) and outside gap between the cylinder (4) inject dust hopper, in the nearly barrel side deposition of dust hopper base plate (9); Isolated air-flow to center flow, forms the center eddy flow that moves upward along radiation shield (6) upper surface under the suction function of center, enter atmosphere; The acceleration air-flow that interior cylinder (2) imports, quicken the rotation of center eddy flow on the one hand, make the particle dust centrifugation once more in eddy flow district, center, and isolated dust is brought into outer eddy flow district, externally eddy flow tangentially quickens on the other hand, improves the separating effect of particle dust and prevents that sticky dust from gluing wall; Base plate during dedusting (9) and airtight contact of control of dust tube (7); Open base plate during dust discharge, make dust fall discharge.
