Description

Technical Field

[0001] The utility model relates to the technical field of metallurgical solid waste, in particular to an iron oxide distribution device. Background Art

[0002] The iron oxide scale or high-purity iron ore powder produced in the steel rolling process is used as raw material, and solid carbon (coke powder or low-sulfur anthracite) is used as reducing agent. The reducing agent and iron oxide scale powder are charged into a silicon carbide refractory tank in a concentric circle distribution method, and then sent into the tunnel kiln by a kiln car. Sponge iron is generated through high-temperature reduction, and then refined through crushing, secondary reduction, powder cake crushing, screening, batching and other processes to form reduced iron powder.

[0003] Specific loading process: a mold is movably arranged inside the silicon carbide refractory tank. The mold is a structure of three coaxially arranged and fixed cylinders in sequence. The outermost cylinder fits the inner wall of the silicon carbide refractory tank to play a positioning role. The mold is used to divide the space inside the silicon carbide refractory tank into three chambers. A reducing agent base is laid at the bottom of the silicon carbide refractory tank. Then the reducing agent is filled in the inner and outer chambers of the mold respectively. Then, the iron oxide powder is filled in the middle chamber of the silicon carbide refractory tank. A layer of reducing agent is covered on the iron oxide powder at the top of the middle chamber. Finally, the mold is taken out of the silicon carbide refractory tank. At this time, the iron oxide powder is in direct contact with the reducing agent. The kiln car on which the silicon carbide refractory tank is placed can be pushed into the kiln regularly for reduction reaction.

[0004] The current method of laying materials is to manually control the feeding. Before covering the iron oxide powder on the top of the middle chamber with the reducing agent, the iron oxide powder needs to be manually smoothed to ensure the laying effect of the reducing agent and reduce the protrusion of iron oxide, which affects the oxidation effect. At present, the feeding and smoothing operations are manually controlled, the work section is complicated, the operation is inconvenient, and the production efficiency is low. Utility Model Content

[0010] Furthermore, a telescopic driving device is fixed to the top end surface of the operating platform, and the telescopic end of the telescopic driving device is fixedly connected to the outer tube.

[0011] Furthermore, the telescopic driving device is any one of an oil cylinder, a pneumatic cylinder or an electric push rod.

[0012] Furthermore, a guide block is fixed on the outer wall of the shell of the material shifting assembly.

[0013] The advantages of the utility model are as follows: the device is used in the iron oxide distribution section. When the silicon carbide refractory tank is moved to the iron oxide distribution section by the kiln car, the iron oxide in the silo is sent to the silicon carbide refractory tank through the screw conveyor and the discharge pipe.

[0021] A silo 2 and a screw conveyor 3 connected to the outlet of the silo 2 are arranged above the operating platform 1. The screw conveyor 3 is a metering type, which ensures the accuracy of feeding and reduces the work intensity of manual feeding. A feeding pipe 4 is fixed to the outlet of the screw conveyor 3. A connecting port 5 matching the feeding pipe 4 is opened on the operating platform 1.

During the movement of the silicon carbide refractory tank 7 on the kiln car along the operating platform 1, the above operations are completed in sequence through each section. This device is used in the iron oxide feeding section. When the silicon carbide refractory tank 7 moves to the iron oxide feeding section under the action of the kiln car, the iron oxide in the silo 2 is sent to the silicon carbide refractory tank 7 through the screw conveyor 3 and the discharge pipe 4. When the iron oxide powder is filled, the iron oxide powder on the top is smoothed using the material shifting assembly 6.

[0023] The material shifting assembly 6 comprises a housing 6.1, a bracket 6.2, a motor 6.3, a material guide cone 6.4, and a shifting rod 6.5. The bracket 6.2 is fixed inside the housing 6.1, the motor 6.3 is fixed to the top end surface of the bracket 6.2, the output end of the motor 6.3 passes through the bracket 6.2 and is fixedly connected to the material guide cone 6.4. The function of the material guide cone 6.4 is to evenly guide the iron oxide powder falling from the feeding pipe 4 to the middle chamber 7.1 of the silicon carbide refractory tank 7. The output end of the motor 6.3 is connected to the bracket 6.2. Rotationally connected, at least two connecting rods 6.6 are fixed to the bottom end of the guide cone 6.4, and a lever 6.5 is fixed to the bottom end of the connecting rod 6.6.

The motor 6.3 is started to drive the guide cone 6.4 to rotate, and the guide cone 6.4 drives the lever 6.5 to rotate. The lever 6.5 smoothes the iron oxide powder to ensure the laying effect of the reducing agent, reduce the protrusion of iron oxide, and affect the oxidation effect. The operation is simple and the production efficiency is high.

[0024] The feeding pipe 4 is a telescopic pipe 4.1, which includes an inner pipe 4.11, an outer pipe 4.12 and a shunt pipe 4.13.

[0029] The specific operation process of this embodiment is as follows:

[0030] During the movement of the silicon carbide refractory tank 7 on the kiln car along the operating platform 1, when the silicon carbide refractory tank 7 moves to the iron oxide material distribution section under the action of the kiln car, the telescopic drive device 8 is started to make the outer tube 4.12 of the feeding tube 4 move downward, and under the action of the guide block 6.7 of the material shifting assembly 6, the material shifting assembly 6 descends until the shell 6.1 contacts the bottom end of the second cylinder of the mold 9, and the telescopic drive device 8 is suspended;

[0031] At this time, the iron oxide in the silo 2 is delivered to the second chamber of the silicon carbide refractory tank 7 through the screw conveyor 3 and the feed pipe 4. When the iron oxide powder is full, the motor 6.3 of the material shifting assembly 6 is started, and the lever 6.5 is used to smooth the iron oxide powder on the top;

[0032] The telescopic drive device 8 is started in reverse to drive the outer tube 4.12 to move upward, so that the material shifting assembly 6 moves upward away from the silicon carbide refractory tank 7, ensuring that the silicon carbide refractory tank 7 continues to move to the next section under the action of the kiln car.
