Abstract
A sealing device of a rotary dryer is formed by connecting the inner side of a framework (1) with filling material (3) through an elastic strip (2), and movably connecting a top fastening bolt (4) on the outer side of the framework (1). Therefore, the sealing device of the rotary dryer has the advantages of low cost, simple replacement, and convenient use, and is especially suitable for being used in the black carbon industry.
Description
Technical field
The utility model relates to a kind of sealing device of rotary dryer, the rotary dryer sealing device that particularly a kind of carbon black industry is used
Background technology
At present, China according to the granulation mode, is divided into two kinds of wet granulation and non-slurry pelletizings in the production of carbon black industry carbon black, because wet granulation granulation intensity is big, dust content is few, easy material feeding when compounding rubber, reduced flying upward property thus, environmental pollution is little, so obtained using widely.On the wet granulation production line, drying machine is a key and huge equipment, drying machine fire-box inside is the hot gas behind the exhaust combustion, temperature 800～1000 degree, so the sealing of drying machine and fire-box just seems extremely important, stainless steel elastic packing piece is adopted in the sealing of now general drying machine and fire-box, sealing surface adopts copper China ink alloy, adopts this sealing, and sealing effectiveness can, but cost is higher, changes trouble.
Summary of the invention
The purpose of this utility model is exactly that the sealing device that a kind of cost is low, change rotary dryer simple, easy to use will be provided.
The purpose of this utility model is achieved in that a kind of sealing device of rotary dryer, it is characterized in that skeleton is inboard by the flexure strip bonding pad, flexibly connects top fastening bolt in the outside of skeleton.
An optimum implementation of the present utility model is: skeleton is at least 24 arc iron plate boxes, and filler is a kind of in graphite block, high temperature resistant asbestos, the powder metallurgy.
The utility model compared with prior art has the following advantages:
Owing to adopted skeleton inboard, flexibly connect the version of top fastening bolt in the outside of skeleton, thereby change simple by the flexure strip bonding pad,, reduce cost, again owing to can adjust the sealing state of drying machine and fire-box at any time, thereby, easy to use, assurance sealing effectiveness.
Description of drawings:
Figure: be the utility model concrete structure schematic diagram
1, skeleton 2, flexure strip 3, filler 4, top fastening bolt
The specific embodiment:
Skeleton 1 adopts iron plate to make, be 24 arc iron plate boxes, flexibly connect filler 3 by flexure strip 2 in its arc, flexure strip 2 is a spring leaf, filler 3 is a kind of in graphite block, high temperature resistant asbestos, the powder metallurgy, flexibly connects top fastening bolt 4 on the arc top in the outside of skeleton 1.
During use, this utility model is installed in drying machine and fire-box junction, can uses, at this moment, sealing surface was attached on the rotary drum housing closely when drying machine rotated, and had played good sealing function, along with dry machine rotates, filler 3 will be worn, at this moment, adjust top fastening bolt 4, make its better sealing, like this, this simple in structure, cost is lower than original seal form, and is more simple when maintenance or replacing simultaneously.
Claims (3)
1. the sealing device of a rotary dryer is characterized in that skeleton (1) is inboard by flexure strip (2) bonding pad (3), flexibly connects top fastening bolt (4) in the outside of skeleton (1).
2. the sealing device of rotary dryer according to claim 1 is characterized in that described skeleton (1) is at least 24 arc iron plate boxes.
