Description
Technical field
The present invention relates to coke over machinery pushing machine field, relate in particular to a kind of lateral smoke blocking device of novel coke oven machine.
Background technology
In coke oven, after a hole coke maturation, pushing machine moves and aims at this fire door.Pushing machine is with door opened, and pushing ram to coke side, enters quenching car to ripe coke slave thruster by coke guide.Flue gas when pushing machine is opened moment of fire door and coke pushing in coking chamber is gushed out from fire door.Modern coke oven is increasingly strict to the requirement of environmental protection, and the flue gas of gushing out from fire door must suck recycling by the dedusting fan on pushing machine, must not directly be thrown in atmosphere.Owing between the smoke guiding cover on pushing machine and coke oven stay, certain distance being arranged, in order to prevent that flue gas from overflowing above the fire door between furnace stay, and flue gas is imported in smoke guiding cover on pushing machine, see Fig. 2, the angle steel 4 of generally burn-oning in two furnace stay inboards, the above lays smoke stop plate 1, opens circular hole on angle steel 4, a slotted hole is opened in the corresponding circular hole of smoke stop plate 1 central position, does not closely connect with bolt between angle steel 4 and smoke stop plate 1.
See Fig. 2, above-mentioned coke oven machine side smoke blocking device Main Problems is:
1, excessive for preventing flue gas, the gap that smoke stop plate 1 and port first speed plate are 3 is too small, smoke stop plate 1 and 3 easy ponding of port first speed plate when raining heavily; Rainwater directly washes away coke oven door when port first speed plate 3 flows down, reduce the fire door temperature;
2, be independently between every smoke stop plate, and smoke stop plate to lean out the part of furnace stay longer.When the smoke stop plate nonuniform heating is out of shape, the easy perk in smoke stop plate bight, during the pushing machine traveling, the scratching smoke stop plate very easily causes the accident;
3, open circular hole on the support angle steel that welds on the furnace stay edge of a wing, a slotted hole is opened in the corresponding circular hole of smoke stop plate central position, has limited the smoke stop plate longitudinal extension.
Summary of the invention
The purpose of this invention is to provide a kind of lateral smoke blocking device of novel coke oven machine, it is simple and reasonable, can reduce calorific loss, flue gas escape, can avoid again bringing the scratching accident because of temperature distortion.
For solving the problems of the technologies described above, technical scheme of the present invention is:
The coke oven machine side smoke blocking device comprises smoke stop plate, supports angle steel, sliding connection plate, port first speed plate, leaves the space of 80～150mm between smoke stop plate one end and port first speed plate, and the port first speed plate of this below, space is provided with leads the rain plate; The smoke stop plate the other end is provided with sliding connection plate, and described sliding connection plate is arranged on the groove in adjacent two smoke stop plate bights, and two smoke stop plates are coupled together; Support angle steel and be provided with horizontal Long Circle bolt hole, the smoke stop plate of correspondence position is provided with vertical Long Circle bolt hole, support the bottom that angle steel is positioned at smoke stop plate, the Long Circle bolt hole of smoke stop plate is aimed at the Long Circle bolt hole that supports angle steel lay, using fixedly, the bolt of smoke stop plate is fixed on smoke stop plate on the support angle steel.
Compared with prior art, the invention has the beneficial effects as follows:
1, owing to having adopted smoke stop plate and band to lead the port first speed plate combination of rain plate, improve the eliminating efficient of rainwater, reduced the calorific loss of coke oven;
2, owing to setting up sliding connection plate between adjacent two smoke stop plate bights, when having avoided the pushing machine traveling, scratching distortion smoke stop plate causes the accident, and has improved the security of operation;
3, owing to having increased at the slotted hole that supports on angle steel, make smoke stop plate flexible more flexible when expanded by heating, avoid the flexible formation torsional deformation that is obstructed of smoke stop plate.

Embodiment
Below in conjunction with accompanying drawing, the specific embodiment of the present invention is described further:
See Fig. 1, Fig. 3, Fig. 4, the coke oven machine side smoke blocking device, by smoke stop plate 1, the support angle steel 4 that is arranged on the smoke stop plate bottom, port first speed plate 3, sliding connection plate 5, fixedly sliding connection plate screw 6, fixedly smoke stop plate bolt 7, lead rain plate 9 and consist of, smoke stop plate 1 one ends and 3 of port first speed plates leave 80～150mm space, the port first speed plate 3 of this below, space is provided with leads rain plate 9, and smoke stop plate 1 the other end is provided with sliding connection plate 5.Sliding connection plate 5 is arranged on the groove in adjacent two smoke stop plate 1 bights, and two smoke stop plates 1 are coupled together.Support angle steel 4 and be provided with horizontal Long Circle connecting hole, the smoke stop plate 1 of correspondence position is provided with vertical slotted hole.
Coke oven machine side smoke blocking device of the present invention is arranged on coke oven stay 2 and horizontal brace 8, and smoke stop plate 1 and 3 of port first speed plates leave long to the space, and are provided with the structure of leading the rain plate, can make that rainwater is smooth and easy to be flowed down, and avoids rainwater directly to wash away coke oven door, reduces the fire door temperature.And leading rain plate 9 can also avoid flue gas excessive from the gap.Can slide in sliding connection plate in the bight of adjacent smoke stop plate, when the smoke stop plate nonuniform heating is out of shape, and the unlikely perk in smoke stop plate bight, when avoiding the pushing machine traveling, the scratching smoke stop plate causes the accident.Have horizontal Long Circle connecting hole on the support angle steel 4 that welds on the furnace stay edge of a wing, have vertical slotted hole on the smoke stop plate of correspondence position.During installation, the fixing bolt used of smoke stop plate, nut can not fasteningly form torsional deformation in case smoke stop plate adds thermal expansion repeatedly.
As shown in Figure 4, first port first speed plate 3 is hung on coke oven cross-brace 8 during installation.Find accurately and support the installation site of angle steel 4 on furnace stay 2 and welding, smoke stop plate 1 Long Circle bolt hole is aimed at the Long Circle bolt hole that supports angle steel 4 to be laid, with the bolt 7 of fixing smoke stop plate 1, smoke stop plate 1 is fixed on and supports on angle steel 4, can not fasteningly form torsional deformation in case smoke stop plate 1 adds thermal expansion repeatedly in the time of fixedly.After adjacent two smoke stop plates 1 install, sliding connection plate 5 is inserted in two smoke stop plate 1 adjacent corners, with the fixing screw 6 of sliding connection plate 5, sliding connection plate 5 is fixed together, smoke stop plate 1 bight is provided with fixed orifices.During this suitable smoke stop plate 1 nonuniform heating distortion, the unlikely perk in smoke stop plate bight, when avoiding the pushing machine traveling, scratching smoke stop plate 1 causes the accident.The main points of installing are that fixedly the bolt 7 of smoke stop plate 1 use can not fasteningly form torsional deformation in case smoke stop plate heats rear expansion repeatedly.
The invention solves the calorific loss that the Water in Rainwater Drainage that causes due to unreasonable structure in prior art removes the bad coke oven that causes; The security incident that cause in the smoke stop plate bight of scratching distortion when having avoided the pushing machine traveling has improved the security of operation; Increase the oval connecting hole that supports on angle steel, smoke stop plate has been stretched more flexible when expanded by heating, avoided the horizontal and vertical flexible torsional deformation that is obstructed and forms that is heated of smoke stop plate, simple, practical, effective.
