Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings and specific embodiments.
The ladle dryer with the air preheating function shown in fig. 1 and 2 comprises a top cover, a pulley fixing bracket 3 and a winch 4; the pulley fixing support and the winch are both arranged on the top beam 1, and the top beam is fixed on the ground through the upright post 2; the top cover can be hung in the air through the upright posts and the top beam, and compared with the ladle dryer in the prior art, the ladle dryer has the advantages of simpler structure and space saving.
The upper end of the top cover is fixedly connected with a lifting chain 5; a fixed pulley block is fixed on the pulley fixing bracket 3; a rope is wound on the winch and wound on the fixed pulley block and extends downwards to be fixedly connected with the lifting chain; the hoisting machine is used for winding and unwinding the rope to control the top cover to ascend and descend, wherein the fixed pulley plays a role in changing the direction of the rope, so that the transverse rope can vertically hoist the top cover.
The fixed pulley block comprises a first fixed pulley and a second fixed pulley, and the first fixed pulley is positioned in the middle of the pulley fixing support and used for changing the direction of a rope for hoisting the top cover. The second fixed pulley is positioned at the edge where the pulley is fixed directly and is positioned on the straight line where the first fixed pulley and the winch are positioned, and because the winch and the first fixed pulley have height difference, when a rope on the winch is directly connected to the first fixed pulley, the rope is easy to rub with the pulley fixing support, so that the rope is abraded; therefore, the second fixed pulley can buffer the height difference between the winch and the first fixed pulley, so that the rope is directly contacted with the second fixed pulley instead of the pulley fixing support, and the rope is protected.
The upper end of the top cover is also provided with a lifting guide frame 10; the lifting guide frame is square; the lift leading truck inserts and arranges in the back timber, and passes the back timber and slide from top to bottom, and the lift leading truck can provide stability guarantee for the lift process of top cap, because the top cap relies on the lift chain to be connected with the rope, can take place to rock in rising or decline in-process unavoidably, has consequently add the lift leading truck on the top cap, relies on the restriction of lift leading truck receiving the back timber, makes the rising of top cap and decline in-process can not take place to rock to increase stability.
The lifting guide frame comprises two vertical rods fixed on the top cover and a limiting rod 11 connected with the two vertical rods; the limiting rod is positioned above the top beam. Because two montants are planted in the back timber, consequently can restrict the displacement of lift leading truck at the gag lever post on two montant tops, when the rope fracture, the top cap whereabouts drives the lift leading truck whereabouts, when the gag lever post fell on the back timber, because the gag lever post has caught the gag lever post, made the gag lever post can not continue the whereabouts to prevented the further whereabouts of lift leading truck and top cap, protected the top cap.
The center of the top cover is fixed with a burner 6, and flame is sprayed out from the burner to bake the bag. The top cover comprises a solid heat-insulating layer 7 and a hollow heat-insulating layer 8, and the hollow heat-insulating layer is positioned at the upper end of the solid heat-insulating layer; the solid heat-insulating layer is made of high-temperature-resistant castable which is the same as that in the prior art, and plays a part of heat-insulating role, but the solid heat-insulating layer has a limited heat-insulating effect as that in the prior art. Therefore, a hollow heat insulation layer is arranged above the solid heat insulation layer.
The hollow heat insulation layer is hollow, and can prevent heat in the casting ladle from continuously radiating upwards on the basis of the casting material. A return air duct with the burner as the circle center is arranged in the hollow heat insulation layer; the outlet of the return air duct is communicated with the elbow air duct, and the inlet of the return air duct is communicated with a combustion-supporting air duct; the end part of the combustion-supporting air pipe is provided with a fan, and an explosion-proof film is also arranged at the position of the fan opening in the combustion-supporting air pipe, so that the explosion-proof function is realized; the burner nozzle is communicated with the hollow heat-insulating layer through an elbow air pipe 9.
The fan blows a large amount of air into the return air duct, and the return air duct surrounds the burner in a return shape, so that the air can travel in the hollow heat-insulating layer for a long enough distance to take away a large amount of heat of the solid heat-insulating layer, and air cooling is realized; the outlet of the return air duct is communicated with the burner through an elbow air pipe, and the heated air is finally sent to the burner for combustion, on one hand, the flame combustion needs the air to provide oxygen for combustion supporting; on the other hand, the normal temperature air is preheated in the hollow heat insulation layer, so that the heat energy of the flame is not lost when the air reaches the flame, and the combustion effect is improved.
The burner is also communicated with a gas pipeline, and the gas pipeline is mainly used for burning coal gas as fuel; an electric regulating valve, a pneumatic quick-cutting valve and a manual ball valve are installed on the pipe body of the gas pipeline so as to provide safety guarantee.
The utility model discloses an application principle does:
the utility model discloses a drive power is provided by installing near the hoist engine, turns to the oscilaltion of drawing lift chain under the supplementary condition of positive position of lift leading truck through the crown block group. The combustion medium is led to the burner arranged at the center of the top cover from a gas pipeline arranged nearby to be combusted, and combustion-supporting air is provided by a fan and enters the burner of the ladle dryer from a combustion-supporting air pipe.
Compared with the prior art, the utility model, the advantage that has does:
a. the utility model has double-layer structure, reduced weight, light overall structure and saved raw material cost;
b. normal temperature air is introduced into the upper layer of the solid heat-insulating layer, so that heat absorbed by the top cover in the baking process can be taken away, the solid heat-insulating layer made of the casting material is cooled, and the air cooling effect is achieved;
