Description

Technical Field

[0001] The utility model relates to the technical field of metallurgical equipment, in particular to a feeding device for a pure oxygen baking furnace. Background Art

[0002] The working principle of a pure oxygen baking furnace mainly utilizes the all-oxygen combustion technology. After natural gas enters the all-oxygen burner, it is mixed with all-oxygen and burned to generate a high-temperature flame. The heat is transferred to the ladle through the combustion chamber wall, so that the molten steel in the ladle is heated and baked.

[0003] The existing feeding device for a pure oxygen baking furnace, for example, a converter molten steel alloy material baking and speed-adjusting feeding device disclosed in the utility model patent with the application number of 201921708475.0, its main structure includes a three-way distributor. The three-way distributor is located below the alloy weighing hopper. The three-way distributor is connected to the alloy baking bin through a chute. An inlet flap valve and an outlet flap valve are respectively installed at the inlet and outlet of the alloy baking bin. The inlet of the electric vibrator feeder is connected to the outlet flap valve. The outlet of the electric vibrator feeder is connected to the inlet of the rotary chute. The outlet of the rotary chute faces the ladle. The hot blast stove is located outside the alloy baking bin. The hot blast pipeline of the hot blast stove is connected to the alloy baking bin; when in use, after the alloy material system issues a baking instruction, the three-way distributor and the inlet flap valve at the upper part of the alloy baking bin are opened in sequence to perform the feeding operation for alloy baking. After the feeding is completed, the inlet flap valve is closed, and the hot blast stove is started to bake the alloy material in the alloy baking bin. After the baked alloy material waits for the system to issue a feeding instruction, the vibrator feeder and the outlet flap valve of the alloy baking bin are opened in sequence to perform the feeding operation for the rotary chute.

[0004] However, most of the existing feeding devices are funnel-shaped, and the feeding rate through the small pipe is relatively slow. Moreover, there are no corresponding protective measures during the movement of the material, and the material is very easy to spill out. Summary of the Utility Model

[0005] To solve the above technical problems, the utility model provides a feeding device for a pure oxygen baking furnace that can not only improve the discharge rate of the material, thereby improving the work efficiency, but also ensure that the material will not overflow during the movement process, reducing the risk of harm to the surrounding workers.

[0006] A feeding device for a pure oxygen baking furnace of the utility model includes a moving mechanism; it also includes a material storage mechanism, a driving mechanism, a traction mechanism, and a capping mechanism. The material storage mechanism is installed on the moving mechanism and stores materials. The driving mechanism is installed on the moving mechanism and drives the traction mechanism and the capping mechanism to move. The traction mechanism is installed on the driving mechanism and pulls the material storage mechanism to rotate. The capping mechanism is installed on the driving mechanism and prevents the materials in the material storage mechanism from spilling out; when feeding is required, the moving mechanism moves below the bunker, the materials enter the material storage mechanism for temporary storage, then the driving mechanism drives the traction mechanism and the capping mechanism to approach the material storage mechanism. The traction mechanism pushes the material storage mechanism vertically, and the capping mechanism seals the feeding port of the material storage mechanism to prevent the materials from spilling out when the moving mechanism moves. After moving above the ladle, the driving mechanism pulls the traction mechanism and the capping mechanism away from the material storage mechanism, causing the material storage mechanism to rotate and tilt, and pouring the materials in the material storage mechanism into the ladle, improving the discharging rate of the materials.

[0007] Preferably, the moving mechanism includes two groups of guide rails, four groups of rollers, a vehicle body, a loading hopper, and two groups of baffles. The two groups of guide rails are installed between the bunker and the ladle. Two groups of rollers are rotatably installed on each group of guide rails. The vehicle body is installed on the four groups of rollers. A discharge chute is opened on the vehicle body. The bottom end of the loading hopper is internally communicated with the top end of the discharge chute of the vehicle body. The top ends of the two groups of baffles are connected to the bottom end of the vehicle body; the vehicle body drives the four groups of rollers to rotate, and the four groups of rollers move along the two groups of guide rails. After the loading hopper moves below the bunker, the bunker discharges materials, and the materials enter the material storage mechanism through the loading hopper for storage. Then the vehicle body drives the four groups of rollers to rotate, driving the vehicle body to move above the ladle. By setting the loading hopper and the two groups of baffles, it is prevented that the materials overflow and hurt the staff below.

[0008] Preferably, the material storage mechanism includes two groups of rotating shafts, a material storage cylinder, a heating hopper, and a connecting seat. The two groups of rotating shafts are respectively installed on the two groups of baffles. The material storage cylinder is rotatably installed on the two groups of rotating shafts. The top end of the heating hopper is connected to the bottom end of the material storage cylinder. A cavity is arranged inside the heating hopper and is communicated with the inside of the material storage cylinder. The connecting seat is installed on the heating hopper; the bunker conveys the materials through the loading hopper and the material storage cylinder to the cavity of the heating hopper, and the heating hopper preheats the materials. When the materials need to be discharged, the traction mechanism pulls the connecting seat to lift the lower part of the heating hopper, making the material storage cylinder and the heating hopper tilt, and the materials quickly discharge through the material storage cylinder. The lower part of the heating hopper is conical to prevent the materials from remaining in the heating hopper.

[0009] Preferably, the driving mechanism includes a motor, a speed reducer, a guard plate, a lead screw, and a slider. The motor is installed on the vehicle body, the speed reducer is installed on the vehicle body, the guard plate is installed on the vehicle body, the lead screw is rotatably installed on the vehicle body and is longitudinally connected to the speed reducer, and the slider is slidably installed on the lead screw; when the material storage mechanism discharges materials, the motor is started, and the motor drives the lead screw to rotate through the speed reducer. The lead screw drives the slider to move away from the material storage mechanism. When loading materials into the material storage mechanism, the motor rotates in the reverse direction to make the slider approach the material storage mechanism.

[0010] Preferably, the traction mechanism includes an ear buckle, a connecting shaft and a pull rod. The top end of the ear buckle is connected to the bottom end of the slider. The connecting shaft is rotatably installed on the ear buckle. One end of the pull rod is connected to the connecting shaft, and the other end of the pull rod is rotatably connected to the connecting seat. When the storage mechanism discharges materials, the slider drives the ear buckle and the connecting shaft away from the storage mechanism. With the length of the pull rod unchanged, the pull rod pulls the connecting seat and gradually moves it toward the side of the speed reducer, thus lifting the bottom end of the heating hopper to facilitate the discharge of materials through the storage cylinder. When loading materials into the storage mechanism, the pull rod pushes the connecting seat to gradually reset, facilitating the loading of more materials.

[0011] Preferably, the capping mechanism includes a support frame, an upper capping, multiple hydraulic cylinders and a lower capping. The bottom end of the support frame is connected to the top end of the slider. The upper capping is installed on the support frame. The top ends of the multiple hydraulic cylinders are connected to the bottom end of the upper capping, and the top end of the lower capping is connected to the bottom ends of the multiple hydraulic cylinders. When the storage mechanism discharges materials, the multiple hydraulic cylinders pull the lower capping upward to make the upper capping and the lower capping close to each other. The support frame moves along with the slider, and the lower capping disengages from the top discharge port of the storage cylinder to facilitate the dumping of materials by the storage mechanism. When loading materials into the storage mechanism, the slider pushes the support frame to block the discharge chute of the vehicle body, and then the multiple hydraulic cylinders push the lower capping downward to block the discharge port of the storage cylinder to prevent material spillage.

[0012] Preferably, both the upper capping and the lower capping are made of recrystallized silicon carbide plates. Recrystallized silicon carbide plates are a kind of high-performance ceramic material that can maintain the stability of its physical and chemical properties at high temperatures, can withstand temperatures up to over 2000 °C, so it is very suitable for use in high-temperature environments. Moreover, it has extremely high crystallinity and density, which endows it with high strength and high hardness and enables it to withstand extreme mechanical stresses.

[0013] Compared with the prior art, the beneficial effects of the present utility model are as follows: When feeding is required, the moving mechanism moves to below the silo, and materials enter the storage mechanism for temporary storage. Then, the driving mechanism drives the traction mechanism and the capping mechanism close to the storage mechanism. The traction mechanism pushes the storage mechanism to be vertical, and the capping mechanism seals the feeding port of the storage mechanism to prevent materials from spilling during the movement of the moving mechanism. After moving above the ladle, the driving mechanism pulls the traction mechanism and the capping mechanism away from the storage mechanism, causing the storage mechanism to rotate and tilt, and pouring the materials in the storage mechanism into the ladle, thus improving the discharge rate of the materials.
