Abstract

At present, known graphite block formula fire-box sealing device has two kinds, and a kind of is that guide position is middle at graphite block, and a kind of is that guide position is at graphite block two ends；Former seals unreasonable structure, so sealing property is bad；Latter sealing structure is out of question, and subject matter goes out over the guide, and this guide is space multistory shape, and structure is complicated, it is impossible to the method that is machined into makes, and by welding method, ten polylith plates can only be welded into a public guide.Due to the unmanageable reason of welding deformation, causing this sealing device gas leakage gap to be strengthened, sealing property is the most bad；Guide pad simple shape of the present invention, can make by standard machinery processing method, and the thickness of guide pad is the half of graphite block thickness, and three faces of guide pad are all sliding sealing surfaces；The two ends of graphite block are crossed guide pad and are fitted tightly, and do not have the gap of gas leakage, reach best sealing effectiveness, and compared with existing two kinds of graphite block sealing devices, sealing property is enhanced about more than once.

Description

A kind of whizzer fire-box sealing device

Technical field

The present invention relates to a kind of carbon black production equipment, especially whizzer fire-box sealing device.

Background technology

Drumdrier is by parts compositions such as rotating cylinder, fire-box, support roller supporting mechanisms.Rotating cylinder two ends are supported by support roller, fire-box Enclose rotating cylinder and be placed in middle part.The periphery of fire-box two ends and rotating cylinder is implemented to seal, and to prevent the flue gas in fire-box excessive, reaches Energy-conservation and environmental protection.Requirement to fire-box sealing device, is good airproof performance, adapts to rotating cylinder roundness defect.At present, known Graphite block formula fire-box sealing device has two kinds, and a kind of is that guide position is in the middle of graphite block；One is that guide position exists Graphite block two ends；Former comes from Colombia (COLUMBIA), and latter comes from Cabot (CABOT).Go out This from Colombian " guide position is in the middle of graphite block ", graphite block is sector, and a sector connects a sector Gather at rotating cylinder outer surface；When two adjacent sectors move inward, the gap of two fan-shaped graphite block neighboring edges reduces, When being displaced outwardly, the gap of two fan-shaped graphite block neighboring edges widens, under normal conditions two fan-shaped graphite block adjacent edges All the time there is gas leakage gap in edge, eliminates.Although graphite block edge is head and the tail convex-concave bridging arrangements at thickness direction, Axially deflation can be blocked, but cannot block and radially become flat.So, come from that Colombian " guide position is in graphite block Between " fan-shaped graphite block device, single says from structural principle, its sealing structure is defective, and sealing property is bad. Come from " guide position is at the graphite block two ends " of Cabot, be double-layer graphite block sealing device.Two end faces of graphite block Being parallel surface, guide is sector；Graphite block and guide are spaced and are arranged in rotating cylinder outer surface；Because rotating cylinder to be adapted to Roundness defect, guide will be with rotating cylinder theory external diameter away from certain distance, so the face that guide is inwardly has gas leakage gap all the time Exist, need second layer graphite block to block；Ground floor seals and second layer sealing is interlaced arrangement, namely second layer stone Ink stick has just blocked the guide of ground floor.This double-layer graphite block sealing device is said from structural principle, and it seals structure Being out of question, sealing property should be out of question.But problem goes out at guide itself.This guide is not only ground floor Graphite block guides, the second layer graphite block guiding that position to be is staggered, and its shape is space multistory, it is impossible to machinery Processing method makes, and by welding method, ten polylith plates can only be welded into a public guide.Owing to welding deformation is difficult to The reason controlled, the morpheme dimensional accuracy of this public guide is inevitable the most bad.In order to ensure inside and outside two-layer graphite block all Can smooth and easy activity in guide, designer has to strengthen graphite block and guide in the free gap of all directions, and this just makes Become the artificial increasing in each guide gas leakage gap, cause the artificial reduction of whole sealing device sealing property.

Summary of the invention

The problem bad in order to solve the sealing property of existing two kinds of graphite block sealing devices, the present invention provides a kind of graphite block close Seal structure.This structure directing part simple shape, manufactures by standard machinery processing method, can guarantee that guide morpheme dimensional accuracy, Reasonable in design, can improve the sealing property of whole sealing device.

The technical solution adopted for the present invention to solve the technical problems is: a kind of whizzer fire-box sealing device, by annular Base plate, guide pad, graphite block, spring assembly, ring baffle form；Annular bottom plate is welded on fire-box end face, guide pad Being uniformly distributed and be fixed on annular bottom plate, the guide pad that each two is adjacent all constitutes a parallel orbit groove；Graphite block is at track Radially slide in groove；Ring baffle keeps off all graphite blocks so that it is can not leave annular bottom plate in respective rail groove；Each Have spring assembly to push graphite block on graphite block face outwardly to draw close to drum surface；It is characterized in that: the thickness of guide pad is About the half of graphite block thickness, two sides of guide pad and the upper surface of guide pad are all sliding sealing surfaces；Graphite block One end is concordant with the side of guide pad, and the thickness from the inside segment length of end face is identical with guide pad thickness；Graphite block another Bottom, one end is concordant with guide pad side, and top againsts guide pad upper surface and stretches out, and epitaxial part has blocked adjoining graphite Their upper surface is also close in the end of block.Graphite block and guide pad in whole sealing device, graphite block slides with graphite block Getting up is all to be close to mutually, does not has the gap of gas leakage, reaches best sealing effectiveness.

The invention has the beneficial effects as follows, compared with existing graphite block sealing device, sealing property is enhanced about more than once, and reaches joint Energy and environmental protection.
