Abstract
The utility model discloses a sealed baffle, which comprises angle steel 1 welded on a cylinder, and a baffle 2 occluded with the angle steel 1, wherein the bending angle of the angle steel 1 is 90 degrees, and the baffle 2 is of a Z-shaped baffle formed by casting ductile cast iron; and a gasket 3 is arranged at the contact part pf the bending angle of the baffle 2 and the angle steel 1, and a rotating shaft 4 is arranged at the center of the baffle 2. The right-angle occluded sealed structure has simple style and has gaskets at the combining parts so as to effectively solve the problem that the metal direct contact type hard sealing structure leaks easily; and simultaneously, the plate is made from ductile cast iron material, thereby effectively solving the problems that the medium corrodes and the plate deforms when heated.
Description
Technical field
The utility model belongs to air channel and the apparatus field in the flue, the sealing baffle specifically of factory of petrochemical refining heating furnace.
Background technology
The existing baffle plate of factory of petrochemical refining problem to a certain extent all occurred in actual use.Subject matter have following some:
1. what baffle plate plate material was generally used is ordinary carbon steel or stainless steel, because all general sulfur-bearing in heating furnace institute of factory of the petrochemical refining fuel burning, in combustion process, oxygen in sulphur and the excess air is in conjunction with forming SOX, temperature reduces the back and meets condensation and form and have the very sulfurous acid or the sulfuric acid of severe corrosive, plate seriously corroded to baffle plate influences the baffle plate performance.
2. in the flue environment of high temperature, can produce distortion after plate is heated, can produce the jam phenomenon between plate after the distortion and the cylinder body, baffle plate is lost should regulating action, has a strong impact on use;
3. the hermetically-sealed construction of existing baffle plate is fairly simple, be plate with cylinder body between the hard sealing that directly contacts.Sealing effectiveness is undesirable, especially plate be corroded or temperature distortion after, sealing effectiveness is poorer;
4. sealing baffle particularly needs to open immediately after air-introduced machine breaks down, and could guarantee furnace operation safety.But because distortion and corrosion are difficult to unlatching sometimes, even can not open.Influenced the safety operation of heating furnace.
Summary of the invention
The purpose of this utility model is in order to overcome the deficiencies in the prior art, and provides a kind of simple in structure, good sealing effect, the sealing baffle of long easy care of life-span.
The technical solution of the utility model realizes in the following manner: sealing baffle comprises: be welded on the angle steel on the cylindrical shell, with the baffle plate of the mutual interlock of angle steel, described angle steel knuckle is 90 °; Described baffle plate is the Z type baffle plate that spheroidal graphite cast-iron is cast, and the knuckle of baffle plate and angle steel contact site are provided with sealing gasket, and its centre position is provided with rotating shaft.
The hermetically-sealed construction form of this right angle biting connecions is simple, adds that binding site has sealing gasket, the leakage problem of effectively having avoided the hard sealing structure of metal direct contact type to be easy to generate.Simultaneously because plate has adopted ductile cast iron material, the very effective problem that has solved etching problem and plate temperature distortion in the medium.
Description of drawings
Fig. 1 is a structural representation of the present utility model
The specific embodiment
, be further described the utility model below in conjunction with description of drawings.
Fig. 1 is a preferred version of the present utility model, has shown sealing baffle, comprising: be welded on the angle steel 1 on the cylindrical shell, with the baffle plate 2 of angle steel 1 mutual interlock, described angle steel 1 knuckle is 90 °; The Z type baffle plate that described baffle plate 2 is cast for spheroidal graphite cast-iron, the knuckle of baffle plate 2 and angle steel 1 contact site are provided with sealing gasket 3, and the center position of baffle plate 2 is provided with rotating shaft 4.
In addition, can determine to increase or reduce the installation quantity of baffle plate 2, reach best sealing effectiveness according to the size of barrel diameter.
The above, it only is preferred embodiment of the present utility model, be not that the utility model is done any pro forma restriction, any those skilled in the art may utilize the technology contents of above-mentioned announcement to be changed or be modified to the equivalent embodiment of equivalent variations, in every case be not break away from the technical solutions of the utility model content,, all still belong in the scope of technical solutions of the utility model any simple modification, equivalent variations and modification that above embodiment did according to technical spirit of the present utility model.
