Description

TECHNICAL FIELD

[0001] The utility model belongs to the technical field of roasting processing equipment, and particularly relates to a roasting metallurgical coke powder recycling device. BACKGROUND

[0002] In the roasting process of anode carbon blocks, the recovery and reuse of metallurgical coke powder are directly related to the reduction of production cost. However, the existing roasting metallurgical coke powder recovery process has the following disadvantages: 1. The recovery method is simple, and the current method is to directly shovel the metallurgical coke powder from the structure of the roasting furnace bottom for recovery. This method has high dependence on the structure of the furnace bottom, and cannot effectively control the falling and scattering of the metallurgical coke powder during the shoveling process, resulting in a large amount of metallurgical coke powder scattered around the furnace bottom, and low recovery efficiency. 2. It is difficult to clean up, and the metallurgical coke powder falls and accumulates around the furnace bottom and in the gaps of the equipment, which needs to be cleaned up again. This not only increases the labor intensity of the cleaning work, but also easily causes wear and tear to the surface of the equipment, increasing the maintenance cost of the equipment.

[0003] In view of the above problems, a roasting metallurgical coke powder recycling device is needed to efficiently recover metallurgical coke powder, reduce scattering and cleaning problems, improve recovery efficiency, and reduce equipment maintenance cost and ensure safety. SUMMARY

[0004] In order to overcome the technical problems described in the background art, the utility model provides a roasting metallurgical coke powder recycling device, which recovers metallurgical coke powder around the structure of the furnace bottom. The metallurgical coke powder is not easy to fall from the structure of the furnace bottom during recovery, and does not need subsequent cleaning, thereby reducing the work intensity and improving the recovery efficiency.

The two side recovery tanks are closely arranged on the front and rear sides of the structure of the furnace bottom, and the two end material blocking structures are closely arranged on the left and right sides of the structure of the furnace bottom. The upper end of the side recovery tank is provided with outwardly extending inclined plates on the front and rear sides, and the front and rear ends of the end material blocking structure are respectively pressed against the opposite outwardly extending inclined plates of the two side recovery tanks.

[0006] Further, the end material blocking structure comprises an end baffle, an end inclined plate and a superimposed inclined plate. The two end inclined plates are fixed together at the opposite ends and extend downwardly at the opposite ends, forming an inverted V-shaped structure. The front and rear ends of the inverted V-shaped structure are respectively provided with superimposed inclined plates. The inclination degree of the superimposed inclined plate with respect to the horizontal plane is greater than the inclination degree of the end inclined plate with respect to the horizontal plane. The superimposed inclined plate is pressed against the corresponding outwardly extending inclined plate. The side of the inverted V-shaped structure is provided with an end baffle which is away from the structure of the furnace bottom during use.

[0007] Further, the upper end of the end baffle is centrally provided with a lifting hole for conveniently lifting the end baffle.

[0008] Further, the upper side of the front and rear ends of the side recycling box is centrally provided with a reinforcing hanging plate, and the reinforcing hanging plate is centrally provided with a lifting hole for lifting.

[0009] Further, the outer side wall of the side recycling box and the outer side wall of the corresponding spreading inclined plate are provided with a plurality of reinforcing ribs for reinforcing connection.

[0010] The present application has the beneficial effects that: the metallurgical coke powder is recovered around the periphery of the furnace bottom structure, the metallurgical coke powder is not easy to fall from the furnace bottom structure during recovery, the coke powder falling from the furnace bottom structure does not need to be cleaned again, the working intensity is reduced, and the recovery efficiency is improved.
