Description

Technical Field

[0001] The utility model relates to a large-scale belt conveyor, specifically, the utility model relates to an environmental protection chute of a belt conveyor, more specifically, the utility model relates to an environmental protection chute used in a belt conveyor under a hopper of a ore screening powder ore return hopper, and is used to solve the environmental protection problem of dust and ash caused by the belt conveyor when conveying materials. Background Art

[0002] Metallurgy, mining, power plants, etc. often require belt conveyors to transport large materials and mineral materials. When belt conveyors transport materials and mineral materials, it is inevitable that materials, mineral materials and mineral powders are mixed. When materials, mineral materials and mineral powders are loaded and unloaded, dust and ash are caused, which is an environmental problem.

[0003] For example, at present, the ore vibrating screen in the blast furnace area of ​​a certain ironmaking plant is an important equipment for feeding the blast furnace raw material system. There are a total of 32 1-4BF raw material ore vibrating screens for the blast furnace. Among them, the lower hopper of the ore screen powder ore return hopper is used to transport powder ore materials, and the ash emission in the belt conveyor chute of the lower hopper is obvious. Because the dust removal pipeline is far away from the lower hopper, it cannot effectively achieve the dust removal effect. If the dust removal pipeline is connected to the return ore hopper, the ore in the return ore hopper will be sucked out, resulting in process waste. Therefore, it is necessary to transform and optimize the internal structure of the lower hopper of the 1-4BF raw material ore screen powder ore return hopper to separate the ore and ore powder, so as to meet the environmental protection requirements of dust removal conditions. Utility Model Content

[0007] An inner hole plate isolation layer is laid under the ore screening powder ore return ore lower hopper to separate the lower hopper into upper and lower layers; the inner hole plate isolation layer is provided with an isolation inner hole, and the isolation inner hole can be used during the operation of the belt conveyor so that block materials such as ore materials are blocked by the inner hole plate isolation layer and retained in the upper layer of the inner hole plate isolation layer, while dust such as ore powder passes through the isolation inner hole of the inner hole plate isolation layer and enters the lower layer of the inner hole plate isolation layer of the lower hopper;

[0008] A stainless steel cylindrical feeding pipe is arranged in the middle of the inner orifice plate isolation layer, and the cylindrical feeding pipe passes through the inner orifice plate isolation layer arranged in the lower hopper, and is used to directly transport the mineral materials retained in the upper layer of the inner orifice plate isolation layer due to obstruction to the outside through the cylindrical feeding pipe arranged in the inner orifice plate isolation layer;

[0009] An air duct is arranged at the lower part of the perforated plate isolation layer in the lower hopper to connect to the dust removal pipeline, and the dust collector is used to safely adsorb and discharge the mineral powder and dust that pass through the perforated plate isolation layer in the lower hopper and enter the lower layer of the lower hopper, so as to effectively separate the mineral material and mineral powder.

[0015] The cylindrical feed pipe made of stainless steel is located at the pipe opening of the inner orifice plate isolation layer of the lower hopper and is formed with a pipe opening edge wall slightly higher than the inner orifice plate isolation layer level.

[0016] According to the utility model, the internal structure of the lower hopper of the ore screening powder ore return hopper is optimized, a cylindrical feed pipe design made of wear-resistant cladding material is adopted, an inner hole plate isolation layer is installed, and stainless steel material is used for corrosion resistance, so that the upper and lower parts of the lower hopper are isolated, and the powder ore is transported through the cylindrical feed pipe. The dust removal pipeline is directly connected to the lower part of each lower hopper through the air duct. Due to the isolation layer, there is no ore in the lower part, so the dust collector can safely absorb dust, and the lower hopper effectively separates the ore and the ore powder. The dust removal pipeline can be directly connected to the inside of the lower hopper, effectively suppressing dust at the first checkpoint, improving the on-site environment, and solving environmental protection problems.

[0017] The inner hole plate isolation layer is made of stainless steel to resist corrosion, and a layer of mineral material is piled up on the upper part to protect it. The powder layer enters the lower layer and is sucked out through the dust removal pipe. The cylindrical feed pipe is made of wear-resistant surfacing material.

Not only the production and maintenance costs are significantly reduced, but the environment is also significantly improved. BRIEF DESCRIPTION OF THE DRAWINGS
