Description

TECHNICAL FIELD

[0001] The present application belongs to the technical field of soft connection sealing of dry bulk material vibration equipment, and particularly relates to a sealed soft connection for a vibration equipment. BACKGROUND

[0002] The sealed soft connection for a vibration equipment uses a single-layer sealing cover, which is used for absorbing vibration and preventing dust. Dry bulk material flying ash can leak into the sealing cover from the gap of the connecting piece. After a period of time, the dust will fill the gap between the sealing cover and the closing piece. The sealing cover absorbs the friction with the dust during movement, which aggravates the wear of the sealing cover, resulting in sealing failure and dust overflow. SUMMARY

[0003] The present application aims to provide a sealed soft connection for a vibration equipment to solve the problem of wear of the sealing cover of the existing soft connection.

[0004] The technical solution of the present application is as follows: The sealed soft connection for a vibration equipment comprises an upper angle steel connecting flange, a lower angle steel connecting flange, an upper closing piece, and a lower closing piece. The upper angle steel connecting flange is used to connect the upper closing piece and the upper interface of the soft connection. The upper closing piece is fixed on the upper angle steel connecting flange. The sealed soft connection further comprises a buffer spring, a sealing filler, a sealing cover, a cover pressing strip, a bolt, and a dust suction port. One end of the buffer spring is connected to the upper closing piece, and the other end is connected to the sealing filler. The sealing filler is located between the upper closing piece and the lower closing piece. The lower closing piece is fixed on the lower angle steel connecting flange. The sealing cover is fixed on the upper angle steel connecting flange and the lower angle steel connecting flange. The lower angle steel connecting flange is fixed on the vibration equipment. The cover pressing strip is pressed on the sealing cover. The bolt is used to fix the cover pressing strip and the sealing cover on the upper angle steel connecting flange and the lower angle steel connecting flange. The dust suction port is arranged at the lower part of the sealing cover.

[0005] Further, the upper angle steel connecting flange, the upper closing piece, the buffer spring, the lower closing piece, and the lower angle steel connecting flange are made of high-strength wear-resistant alloy steel. The sealing filler is made of wear-resistant rubber. The sealing cover is made of fiber fabric. The cover pressing strip and the bolt are made of stainless steel. The dust suction port is made of transparent polycarbonate.

[0006] Further, the part of the upper closing piece that contacts the material has an inclination angle to prevent material accumulation. The inclination angle r is 50°-90°.

[0007] The application has the following advantages: 1. A sealing filler layer is added to the soft connection of the existing single-layer sealing cover, and the material of each part of the soft connection is optimized to prevent dust from entering the soft connection sealing cover layer and causing wear of the sealing cover, thereby prolonging the service life of the soft connection; 2. A transparent observation dust suction port is arranged at the lower part of the sealing cover, so that dust overflowing from the sealing filler layer to the sealing cover layer can be sucked out to prevent wear of the sealing cover.

[0011] The technical solutions in the application will be further described below in combination with examples and the drawings.

[0012] Figure 1 As shown in the figure, the sealing soft connection for a vibrating device comprises an upper angle steel connecting flange 1, an upper closure 2, a buffer spring 3, a sealing filler 4, a lower closure 5, a lower angle steel connecting flange 6, a sealing cover 7, a cover pressing strip 8, a bolt 9, and a dust suction port 10. The upper angle steel connecting flange 1 is used to connect the upper closure 2 and the upper interface of the soft connection; the upper closure 2 is fixed on the upper angle steel connecting flange 1; the buffer spring 3 is connected to the upper closure 2 at one end and to the sealing filler 4 at the other end; the sealing filler 4 is located between the upper closure 2 and the lower closure 5; the lower closure 5 is fixed on the lower angle steel connecting flange 6; the sealing cover 7 is fixed on the upper angle steel connecting flange 1 and the lower angle steel connecting flange 6; the lower angle steel connecting flange 6 is fixed on the vibrating device; the cover pressing strip 8 is pressed on the sealing cover 7; the bolt 9 is used to fix the cover pressing strip 8 and the sealing cover 7 on the upper angle steel connecting flange 1 and the lower angle steel flange 6; and the dust suction port 10 is arranged at the lower part of the sealing cover 7. The dust suction port is used to suck out dust overflowing from the sealing filler layer to the sealing cover layer to prevent wear of the sealing cover.

[0013] The upper angle steel connecting flange 1, the upper closure 2, the buffer spring 3, the lower closure 5, and the lower angle steel connecting flange 6 are made of high-strength wear-resistant alloy steel; the sealing filler 4 is made of wear-resistant rubber material; the sealing cover 7 is made of fiber fabric material; the cover pressing strip 8 and the bolt 9 are made of stainless steel material; and the dust suction port 10 is made of transparent polycarbonate material.

[0014] The part of the upper closure in contact with the material has an inclination angle to prevent material accumulation, and the inclination angle r is 50°-90°. The buffer spring 3 and the sealing filler 4 can prevent dust and absorb vibration displacement; the sealing cover 7 can prevent dust and absorb vibration displacement.

[0015] Working process and principle: The upper angle steel connecting flange 1 is used to connect with the upper interface of the flexible connection, the upper closure 2 is welded to the inner side of the upper angle steel flange 1, and the part in contact with the material is provided with an inclination angle to prevent local blockage of the material; the lower angle steel connecting flange 6 is connected with the vibration equipment, and the lower closure 5 is welded to the inner side of the lower angle steel connecting flange 6. The upper closure 2 and the lower closure 5 form the main closed area, and there is a gap between the upper closure 2 and the lower closure 5. The buffer spring 3 and the sealing filler 4 are arranged between the gap of the upper closure 2 and the lower closure 5. When the equipment vibrates, the buffer spring 3 and the sealing filler 4 can absorb the vibration displacement, prevent dust from overflowing to the sealing cover 7 and the lower closure 6, and cause the sealing cover 7 to be worn out by rubbing with the material. The fiber fabric material sealing cover 7 is fixed between the outer sides of the upper angle steel connecting flange 1 and the lower angle steel connecting flange 6 by the cover pressing plate 8 and the bolt 9. The sealing cover 7 is in a relaxed state, can absorb vibration displacement, prevent the leakage of the sealing filler 4 from overflowing, and achieve a double protection effect. At the same time, a transparent dust suction port 10 is arranged below the sealing cover 7. When the sealing filler 4 is worn out and the material overflows between the sealing cover 7 and the lower closure 6, the dust suction port can be opened to suck away the material, preventing the sealing cover 7 from being worn out.

[0016] The upper angle steel connecting flange 1, the upper closure 2, the buffer spring 3, the lower closure 4, and the lower angle steel connecting flange 6 are made of high-strength wear-resistant alloy steel material; the sealing filler 4 is made of wear-resistant rubber material; the sealing cover 7 is made of fiber fabric material; the cover pressing strip 8 and the bolt 9 are made of stainless steel material; and the dust suction port 10 is made of transparent polycarbonate material, so as to reduce the wear of the components of the sealing flexible connection and prolong the service life of the sealing flexible connection.
