Description

Technical Field

[0001] This utility model belongs to the technical field of blast furnace ironmaking production equipment, specifically relating to an environmentally friendly and efficient static material distributor for blast furnace high-rise material bins. Background Technology

[0002] The blast furnace overhead charging silo is a crucial component of blast furnace ironmaking, used for storing materials and supplying finished products to the blast furnace. Traditional overhead charging silos have welded metal gratings at the inlet to filter large pieces of material and prevent personnel from falling in. However, these metal gratings have several drawbacks and shortcomings:

[0003] 1. Metal gratings are subject to long-term material impacts, resulting in a generally short lifespan and frequent replacement, which increases maintenance costs.

[0004] 2. When the material falls from the unloading trolley conveyor belt through the side chutes to the elevated silo, it collides violently with the metal grid, causing a large amount of material to break and produce unqualified material, which is not conducive to the production operation of the blast furnace.

[0005] 3. The rapid wear of the metal grid caused by material impact and breakage increases the workload of maintenance and further increases the cost of manpower and materials.

[0006] 4. The impact of materials causes splashing and scattering, resulting in a large amount of dust and pollutants, which seriously affects the health of on-site employees and increases the workload of dust collection. Utility Model Content

[0007] The purpose of this invention is to provide an environmentally friendly and efficient static material distributor for blast furnace elevated material bins, in order to solve the problems mentioned in the background art.

[0008] To achieve the above objectives, this utility model provides the following technical solution:

[0009] An environmentally friendly and efficient static material distributor for a blast furnace overhead silo includes two outer frames. A first material guide and a second material guide are fixedly connected between the two outer frames. A receiving layer is laid on the top surface of the first and second material guides. Hinges are fixedly connected to both sides of the bottom of the first material guide, and a damping curtain is fixedly connected to the other end of the hinge.

[0010] Preferably, the outer frame, guide frame one, and guide frame two are formed by welding steel plates.

[0011] Preferably, the material of the receiving layer is a wear-resistant ceramic material.

[0012] Preferably, the damping curtain is made of a high-molecular wear-resistant material.

[0013] Preferably, the length of the inclined surface of the second guide frame near the first guide frame is 1.4 meters.

[0014] Preferably, the length of the outer frame is 1.5 meters.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] 1. In this utility model, the inclined receiving surface design is adopted to avoid direct impact between the material and the metal grid, reduce material breakage, and improve material quality.

[0017] 2. In this utility model, the inside of the feeder is lined with wear-resistant ceramics, which improves the wear resistance and service life of the equipment and reduces maintenance costs.

[0018] 3. In this utility model, the setting of the polymer wear-resistant damping curtain further reduces the material speed and plays a sealing role, effectively preventing dust pollution and improving the working environment of on-site employees.

[0019] 4. This utility model is easy to install. Due to its segmented design, installation and replacement after damage are extremely convenient.
