Abstract
The invention discloses a radial adjustable double dust-proof sealing device applied to building material, power station, mine and chemical industries and the like. The device comprises a hot air chamber, a scraping plate, an abrasive disc seat, a sealing collar and the like. The device is divided into double dust-proof seals, wherein the first seal is composed of a first sealing plate of the scraping plate and a second sealing plate of the hot air chamber, the scraping plate is consolidated to the abrasive disc seat by bolts, the second sealing plate is welded on the hot air chamber, and the first sealing plate is welded on the scraping plate, thereby forming a labyrinth seal; and the second seal is composed of a first sealing ring, a second sealing ring, a third sealing ring and the sealing collar, the first sealing ring is welded on the hot air chamber and is provided with a strength-enhanced rib plate, the sealing collar is annular and is distributed along the circumferential direction, and the sealing collar is tightly clamped by the second sealing ring and the third sealing ring and consolidated to the first sealing ring. The device disclosed by the invention changes the sealing adjustment direction and adopts a combined sealing structure, so that the sealing effect is more reliable.
Description
Technical field
The present invention relates to a kind of radial adjustable double dust-proof sealing device of vertical roll grinder in the industries such as building materials, power station, mine, chemical industry.
Background technology
At present, existing hermetically-sealed construction is the sealing of adjustable ring shaped axial, by the gap of bolt axial adjustment abrasive disk seat and sealing ring, forms the positive seal chamber, but bolt is far away apart from the abrasive disk seat bottom closing, and is difficult to afterwards adjusting in disposable installation.Separately due to heavy castings and weldment process and assemble error, sealing effectiveness is poor.Therefore, a kind of radial adjustable double dust-proof sealing device of development is the new problem of being badly in need of solution.
Summary of the invention
The purpose of this invention is to provide a kind of radial adjustable double dust-proof sealing device, be the vertical roll grinder double dust-proof sealing device, one resealing is the labyrinth sealing that the sealing plate of hot air chamber and scraper plate forms, the double radial adjustable sealing that is sealed into bolt, sealing ring, sealing ring composition, change sealing and regulate direction and adopt combined sealing structure, make sealing effectiveness more reliable.
The object of the present invention is achieved like this: a kind of radial adjustable double dust-proof sealing device, whole device is comprised of hot air chamber, scraper plate, abrasive disk seat, the first sealing plate, the second sealing plate, the first sealing ring, the second sealing ring, the 3rd sealing ring, sealing ring, this device is divided into double dust-proof sealing, one resealing is comprised of the first sealing plate of scraper plate and the second sealing plate of hot air chamber, scraper plate is bolted on abrasive disk seat, the second sealing plate is welded on hot air chamber, the first sealing plate is welded on scraper plate, forms labyrinth sealing; Two resealings are comprised of the first sealing ring, the second sealing ring, the 3rd sealing ring and sealing ring, the first sealing ring is welded on hot air chamber, and be provided with the gusset of gaining in strength, sealing ring is that annular is along the circumferential direction arranged, clamps and is connected on the first sealing ring with the second sealing ring, the 3rd sealing ring; The operation principle of described device is, one resealing middle scraper and abrasive disk seat rotate simultaneously, the gap of material by scraper plate and hot air chamber enters a resealing chamber that is comprised of scraper plate inwall, hot air chamber inwall, the first sealing plate, the second sealing plate, scraper plate and hot air chamber inwall that material touches the sealing plate lower plane fall, and reach sealing purpose; Slotted hole in two resealings on the second sealing ring can be realized radially adjusting, and abrasive disk seat bottom outer wall surface precision can obtain by processing, and the gap of abrasive disk seat and sealing ring is controlled, and sealing is reliable.
Main points of the present invention are its structure and operation principle.Its operation principle is, one resealing middle scraper and abrasive disk seat rotate simultaneously, the gap of material by scraper plate and hot air chamber enters a resealing chamber that is comprised of scraper plate inwall, hot air chamber inwall, the first sealing plate, the second sealing plate, material touches sealing plate lower plane scraper plate and the hot air chamber inwall falls, and reaches sealing purpose; Slotted hole in two resealings on the second sealing ring can be realized radially adjusting, and abrasive disk seat bottom outer wall surface precision can obtain by processing, and the gap of abrasive disk seat and sealing ring is controlled, and sealing is reliable.
Radial adjustable double dust-proof sealing device compared with prior art, have and be the vertical roll grinder double dust-proof sealing device, one resealing is the labyrinth sealing that the sealing plate of hot air chamber and scraper plate forms, the double radial adjustable sealing that is sealed into bolt, sealing ring, sealing ring composition, changing sealing regulates direction and adopts combined sealing structure, make the advantages such as sealing effectiveness is more reliable, will be widely used in the industries such as building materials, power station, mine, chemical industry.
