Description
Technical field
The utility model relates to the vehicle-mounted smoke pipe field of leading of furnace roof of coke-oven plant's tamping coke furnace, relates in particular to a kind of changing of the relative positions opening device of coke oven lid.
Background technology
When the flue gas that current domestic coke-oven plant tamping coke furnace produces when improvement is coaling escapes problem, main what adopt is that the vehicle-mounted smoke pipe of leading of furnace roof is led cigarette and realized with the mode that the burner smoke ground station for dust removal combines.
See accompanying drawing 1, when certain coking chamber of tamping coke furnace need to be coaling, furnace roof smoke guiding bogie (1) at first drives to the coking chamber top of coalingging, make to lead smoke pipe (2) one ends by the adjustment contraposition and aim at this coking chamber fire door (18) of coalingging, lead the smoke pipe the other end and aim at another in the coking coking chamber fire door in latter stage.Under the connection effect of leading smoke pipe, flue gas is imported to N+1 coking chamber from N coking chamber like this.Lead the cigarette effect in order to improve, increased the measure of winding-up high pressure aqua ammonia on N+1 coking chamber termination upcast on technique, suction ejector action by high pressure aqua ammonia by the flue gas injection in effuser, thereby that has realized continuous and effective leads the cigarette effect, wherein in high pressure aqua ammonia injection and coaling initial stage and coking coking chamber in latter stage, the poor and pressure reduction of exhaust gas volumn is the motivating force of leading cigarette.
Said process is the vehicle-mounted basic model of leading cigarette of current tamping coke furnace, good leads the load that the cigarette effect can greatly reduce the burner smoke ground station for dust removal.This leads the cigarette process can be summarized as the following steps:
The first step: smoke guiding bogie drives to the coking chamber top, N hole that need to coaling;
Second step: lead smoke pipe (2) contraposition, make the one end aim at N hole coking chamber fire door, the other end is aimed at N+1 hole coking chamber fire door;
The 3rd step: lead smoke pipe and fall leading under smoke pipe hoisting appliance (4) effect, until cover N+1 hole coking chamber fire door and N hole coking chamber fire door fully;
The 4th step: furnace cover lifting mechanism (3) descends, and utilizes hand to grab bell (5) is lifted, until lead smoke pipe top (more than Y-tube), guarantees to lead the connectedness of smoke pipe, so that flue gas imports and exports smoothly;
The 5th step: it is complete to lead cigarette, the end of coalingging, and bell (5) resets under the effect of furnace cover lifting mechanism;
The 6th step: lead smoke pipe and rise and sail out of with smoke guiding bogie leading under the effect of smoke pipe hoisting appliance;
The 7th step: due to bell not with the tight combination of body of heater, in coking chamber under positive pressure flue gas can escape from gap, so the workman scene need to seal slurry (6) with bell the bell surrounding is sealed.
Above-mentioned technical process, when leading cigarette, exists very large potential safety hazard and the problem that affects the normal stably manufactured of body of heater.Problem goes out on above-mentioned the 4th step and the 7th step, be mainly manifested in: when the workman seals slurry (6) with bell, just form very strong cohesive force while being sealed, this is afterwards when carrying out the 4th step, " stretched the meaning " operating method of formula of bell lifts, because furnace cover lifting mechanism only lifts and acts on bell at vertical direction, body of heater destroyed phenomenon under the cohesive force effect of bell often appears in production practice, the destruction that comprises the body of heater member, form very large potential safety hazard, also have a strong impact on stable normal production of coke oven.
Summary of the invention
The purpose of this utility model is to provide a kind of changing of the relative positions opening device of coke oven lid, overcome existing technical deficiency, in execution, lead in the cigarette process, when leading after smoke pipe falls and seal fire door, first by topworks, make bell rotate the changing of the relative positions on horizontal plane, destroy the bounding force of bell sealing slurry between bell and body of heater, then separate bell and body of heater, avoid the process of uncapping to cause body of heater to destroy, realize safety, stably manufactured.
For achieving the above object, the technical solution of the utility model is:
A kind of changing of the relative positions opening device of coke oven lid, comprise outer tube, changing of the relative positions sleeve pipe, cylinder and ear handle bell, outer tube is nested with the outside at changing of the relative positions sleeve pipe, outer sleeve inner wall and changing of the relative positions sleeve outer wall are slidably matched, along the circumferential direction minimumly on outer tube be provided with two oval through holes, two relative outer tube centrosymmetry of oval through hole, the outer wall of the changing of the relative positions sleeve pipe corresponding with oval through hole is provided with push rod, the outside at outer tube is provided with cylinder, the piston rod end of cylinder and the end of push rod are hinged, the inwall of described changing of the relative positions sleeve pipe is provided with several and pushes away handle, pushing away handle is uniformly distributed along the inwall of changing of the relative positions sleeve pipe, when installing in open site, pushing away handle is meshed with the ear handle on the ear handle bell.
The described handle that pushes away is 1:(2 ~ 3 with the ratio of the quantity of ear handle).
The described engagement part cross section, end that pushes away handle and ear handle is trapezoidal.
The upper edge of described changing of the relative positions sleeve pipe is placed in the slideway of outer sleeve inner wall, between the upper edge of changing of the relative positions sleeve pipe and slideway and under outer tube along being equipped with high-temperature resistant seal ring.
Compared with prior art, the beneficial effects of the utility model are:
1) the employing changing of the relative positions rotatablely moves and overcomes the bounding force of bell sealing slurry between bell and body of heater, thereby realizes the safe separating of bell and body of heater, avoids directly lifting the rigid destruction of the body of heater caused.
2) apparatus structure is brief, and dependable performance economy can realize automatization control.
