Description

TECHNICAL FIELD

[0001] The utility model relates to coal storage silo technical field, concretely relates to a kind of wear plate and coal storage silo of anti-leakage coal accumulation prevention. BACKGROUND

[0002] Coal storage silo is the important industrial facility indispensable in coal industry, especially circular silo is most common.In long-term use process, the impact of coal, coal slime water corrosion and wear layer abrasion inevitably lead to silo wall breakage, shedding and cracking etc.Problems.The main methods of silo repair currently include two forms of assembly type wear plate repair and smearing pressure non-shape high-strength cement-based material repair.

[0003] When repairing operation is carried out using assembly type wear plate in actual application, since most wear plates are overall rectangular or square, plate edge is plane.In installation, butt joint is used between plate, after construction is completed, gap is left at wear plate butt joint, these gaps can be perpendicular to silo wall.Due to installation accuracy difference, the width of plate joint is also not same, with time elapsing, coal powder can continuously penetrate into silo wall through these gaps.Meanwhile, silo is dusted through spray system in operation process, coal slime water formed after spray water and coal powder are mixed has strong corrosiveness, long-term effect can corrode silo wall and wear plate, form damaged area.

[0004] When coal in silo falls from high place, it can impact local wear plate.Due to wear plate is usually fixed by three points or four points, middle part of plate is prone to hollow, leading to wear plate subjected to long-term impact to be recessed to silo wall, and horizontal faulting is formed at butt joint with adjacent wear plate not subjected to impact.Faulting place is prone to accumulate coal, with time elapsing, accumulated coal continuously increases, once large-area faulting is formed, it can lead to silo blockage, seriously affect normal production operation.Meanwhile, accumulated coal at faulting place gradually increases in temperature in long-term accumulation process, has spontaneous combustion risk, potential harm is great.

[0005] In order to solve the defects existing in prior art, anti-leakage coal accumulation prevention wear plate and coal storage silo are urgently needed, which can effectively prevent coal leakage and coal accumulation, and avoid potential safety risks. UTILITY MODEL CONTENT

[0006] The utility model intends to provide anti-leakage coal accumulation prevention wear plate and coal storage silo, effectively solve the problem of coal leakage and coal accumulation caused by loose butt joint of wear plate joint in coal storage silo repair engineering, and avoid potential safety risks.

[0007] To achieve the above object, the utility model adopts the following technical solutions:

[0008] The wear-resistant plate material for preventing leakage and coal accumulation comprises a plurality of wear-resistant plates assembled together, the wear-resistant plates comprising a top wear-resistant plate, a bottom wear-resistant plate and at least one middle wear-resistant plate, the top wear-resistant plate having a planar or inclined surface structure, the inclined surface structure being directed towards the center of the coal storage silo, the wear-resistant plates having a uniform thickness, and the longitudinal section of the joint between the wear-resistant plates having a concave-convex structure, the concave-convex structure having a lowest point on the side directed towards the center of the coal storage silo.

[0009] The coal storage silo comprises a reinforced concrete wall, the wear-resistant plate, a grouting layer and a fixing mechanism, and the reinforced concrete wall, the grouting layer and the wear-resistant plate are arranged in layers from the outside to the inside; the fixing mechanism comprises a T-shaped fixing member, a T-shaped anchor member, an L-shaped fixing member and an arc-shaped reinforcing bar, the end of the horizontal part of the T-shaped anchor member is fixedly connected to the inner wall of the wall, and the remaining part of the T-shaped anchor member is fixed in the grouting layer; the end of the horizontal part of the L-shaped fixing member is fixed perpendicularly to the inner wall of the wall, the arc-shaped reinforcing bar is welded to the inner corner of the L-shaped fixing member, the end of the horizontal part of the T-shaped fixing member is provided with a hook, the horizontal part of the T-shaped fixing member passes through the wear-resistant plate and is fixed to the arc-shaped reinforcing bar through the hook, the vertical part of the T-shaped fixing member is located on the side of the wear-resistant plate away from the inner wall of the wall, and the wear-resistant plate is tightly attached to the grouting layer.

[0010] The principle and advantages of the present scheme are as follows:

[0011] According to the actual situation, the connection structure of the existing wear-resistant plate is improved to fundamentally solve the problems in the prior art, and the present scheme is mainly used for repairing old coal storage silos.

[0012] The wear-resistant plates required according to the size of the area to be repaired are divided into top wear-resistant plates, middle wear-resistant plates and lower wear-resistant plates according to the installation position, so as to ensure that the wear-resistant plates assembled together can completely cover the repaired area, the inclined surface of the top wear-resistant plate can make the coal powder slide down, and prevent the coal powder from accumulating on the top of the wear-resistant plate to form accumulated coal. In addition, the ingenious design of the inclined surface structure also enhances the stability of the overall structure. When the coal impacts on the top of the wear-resistant plate, the inclined surface can play a role in unloading force, dispersing the direct impact force through the inclined surface, improving the stability and service life of the wear-resistant plate. The joint between the wear-resistant plates has a concave-convex structure, and the lowest point of the concave-convex structure is on the side directed towards the center of the coal storage silo. Firstly, the concave-convex structure can effectively prolong the leakage path and strengthen the connection strength between the wear-resistant plates. Secondly, since the lowest point of the concave-convex structure is on the side directed towards the center of the coal storage silo, the gravity can be used to prevent the coal slurry from seeping into the wall through the gap between the wear-resistant plates, thereby solving the problems of coal leakage and accumulation, achieving the goal of preventing coal leakage and accumulation, and avoiding potential safety risks.

[0013] The damaged area is fixed with T-shaped anchors, the bottom layer of the damaged area is fixed with bottom wear plates, the top layer is fixed with top wear plates, and the middle layer is fixed with middle wear plates. First, the bottom wear plates are fixed through the fixing mechanism, then the concave-convex structures of the middle wear plates and the bottom wear plates are aligned, and the layers are sequentially connected and fixed, and finally the installation of the top wear plates is completed. The T-shaped anchors are used to anchor the grouting material layer to strengthen the connection strength between the grouting material layer and the inner wall of the coal storage silo, and the wear plates are fixed on the inner wall of the coal storage silo through the fixing mechanism. In this way, the wear plates fixed and installed in a splicing manner form a new protective barrier with anti-seepage and anti-coal accumulation functions. Then, grouting material is poured between the damaged area and the wear plates to fill the damaged pores and form a grouting material layer to further strengthen the fixation and complete the repair of the coal storage silo.

[0014] Preferably, as an improvement, the concave-convex structure is in a stepped shape, the step near the center of the coal storage silo is lower, and the width of the step is 1 / 2 of the plate thickness, and the step height is uniform.

[0015] This stepped structure design not only ensures the tight engagement between the wear plates, but also effectively prevents misalignment between the layers, enhancing the overall impact resistance of the grouting material layer. Moreover, the stepped connection joint after splicing has a higher step on one side closer to the inner wall of the silo than on the other side, effectively preventing the penetration of slurry and coal powder, and effectively protecting the inner wall of the coal storage silo.

[0016] Preferably, as an improvement, the concave-convex structure is in a convex shape, and the width of the convex part of the convex shape is 1 / 3 of the plate thickness.

[0017] To further enhance the connection stability between the wear plates, a concave-convex butt joint structure is designed, which has stronger structural stability under the impact of coal after splicing and tightening, further improving the anti-misalignment effect, reducing the possibility of misalignment structure, and thus improving the overall stability.

[0018] Preferably, as an improvement, the concave-convex structure is a slope surface, and the slope surface faces the center of the coal storage silo.

[0019] Based on the above wear plate structure, further optimization and improvement are made, and the concave-convex structure is a slope surface, and the slope surface faces the inside of the coal storage silo. Under the action of gravity, most of the slurry cannot complete the penetration and will directly fall down along the slope surface, which can effectively prevent the slurry from flowing into the gap and further improve the protection performance.

[0020] Preferably, as an improvement, the concave-convex structure is a slope surface with a convex shape in the middle, and the slope surface faces the center of the coal storage silo.

[0021] On the basis of the above wear plate structure is further optimized and improved, the butt joint is designed as a slope surface, and the slope surface faces the coal storage silo, and in order to further enhance the connection strength and connection stability between the wear plates, the middle part is in the shape of a convex character, which can effectively prevent relative sliding between the wear plates and improve the overall stability. Under the action of gravity, most of the coal slurry water cannot complete the penetration and will directly fall along the slope surface, which can effectively prevent the coal slurry water from flowing into the gap and further improve the protection performance.
