Description

Technical Field

[0001] The utility model relates to the technical field of silo discharge port protection, and more specifically, to a silo discharge port anti-wear device. Background Art

[0002] As a new, environmentally friendly and efficient material storage structure, steel structure gravel silo has been widely used in the building materials industry. Building material gravel is transported to the steel structure silo by a belt conveyor. The effective volume of the silo can generally store two days of production. Parallel gate valves and fan valves are installed under the silo to discharge the material to the truck loading-ground scale weighing and transportation system. The truck loading and weighing reaches the set value and is transported out. The empty truck scans the license plate on the ground scale, stops at the designated position, discharges the material to the set weight, takes the ticket and goes down the ground scale. The entire loading and data storage time does not exceed four minutes. Compared with the original stacking shed-shoveling system, the stacking, weighing and transportation system consisting of building material aggregates entering the silo-ground scale-truck: 1. It improves the automation level and labor production efficiency, which reduces the number of employees and increases the efficiency of the owner unit; 2. The loading and weighing time is greatly shortened, which saves the waiting time of the vehicle and improves the logistics and transportation efficiency; 3. It reduces the dust generated when stacking and shoveling in the shed, which meets the national environmental protection requirements for building green and low-carbon mines.

[0003] The building material aggregates entering the silo are divided into two particle sizes: 5-15mm and 15-25mm. The lower discharge part of the silo is a steel structure cone bucket. Although the cone bucket is made of wear-resistant steel plate with a diameter of δ=16mm during processing, the hardness of the building material aggregates is relatively large and the discharge port is square. In the long-term production process, the discharge port is the most worn and easily worn through. Therefore, a wear-resistant device for the discharge port of a steel structure gravel silo is designed to ensure the stable operation of the silo-scale-truck storage, weighing and transportation system, which will directly affect the production efficiency of the system.

[0004] The patent with announcement number CN217599348U discloses an anti-wear device for a discharge port of mineral admixtures, wherein a discharge pipe is clamped at the bottom end of the discharge hopper, and an anti-collision and anti-wear mechanism is arranged inside the discharge pipe, and the anti-collision and anti-wear mechanism includes a swivel, a vertical cylinder, an embedding groove, a connecting block, a sealing plate, a cross anti-collision plate, a pad and a latch. By embedding the cross anti-collision plate into the discharge pipe, the mineral admixture is blocked when it slides along the inner bucket to prevent the mineral admixture from colliding with the inside of the discharge pipe, thereby reducing the wear of the discharge pipe. However, the design structure is relatively complicated, and the production and installation are inconvenient. Moreover, the replacement of the anti-wear mechanism after damage is also cumbersome, and it is not suitable for popularization and application. Utility Model Content

In addition, the terms "first", "second", and "third" are used for descriptive purposes only, and cannot be understood as indicating or implying relative importance.

[0033] The utility model is further described below in conjunction with embodiments.

[0034] Example

[0035] Combination Figure 1 and Figure 2 As shown, a silo discharge port anti-wear device of the present embodiment includes a silo 100, a bottom plate 103 is provided at the bottom of the silo 100, and a through hole is opened on the bottom plate 103 as a discharge port; specially, at least one layer of wear-resistant pipe 200 is provided inside the silo 100 above the bottom plate 103, the inner cavity opening of the wear-resistant pipe 200 in contact with the bottom plate 103 is not larger than the opening of the discharge port on the bottom plate 103, and an edge sealing plate 201 is circumferentially provided on the outer wall of the wear-resistant pipe 200, and the edge sealing plate 201 can close the gap between the wear-resistant pipe 200 and the discharge port on the bottom plate 103; the wear-resistant pipe 200 extends upward in the vertical direction inside the silo 100, and a discharge area 101 is formed above the top of the wear-resistant pipe 200, and a material accumulation dead angle area 102 is formed circumferentially around the outer wall of the wear-resistant pipe 200.

[0036] In this embodiment, by arranging the wear-resistant pipe 200 above the discharge port, when the material is flushed, only the wear-resistant pipe 200 is flushed and the discharge port is not flushed, thereby effectively avoiding the wear of the discharge port, and the wear-resistant pipe 200 can be replaced separately as an independent component, which saves costs and is convenient to replace. In practice, the wear-resistant pipe 200 and the bottom plate 103 are preferably installed in a detachable manner, specifically fixed by spot welding, which not only ensures a high position matching stability, but also can be directly dragged and separated to achieve detachability when replacement is needed, which is convenient to operate. And because the wear-resistant pipe 200 extends upward to a certain height inside, a discharge area 101 is formed above the wear-resistant pipe 200, and a material accumulation dead angle area 102 is formed around the wear-resistant pipe 200. The material accumulated here is also supported on the outside of the wear-resistant pipe 200 from the circumferential direction, further ensuring the position stability of the wear-resistant pipe 200, preventing it from shifting, avoiding the formation of a gap between the wear-resistant pipe 200 and the discharge port of the bottom plate 103, and fully avoiding the discharge port on the bottom plate 103 being worn due to the material falling out of the gap.

[0037] In order to facilitate the replacement of the wear-resistant pipe 200, it can be further optimized that multiple groups of wear-resistant pipes 200 are arranged in the silo 100, and the diameters of the multi-layer wear-resistant pipes 200 decrease in sequence in the upward direction away from the bottom plate 103; an edge sealing plate 201 is arranged on the outer wall of each layer of wear-resistant pipe 200, so as to close the gap between the upper and lower layers of wear-resistant pipes 200. Preferably, the multi-layer wear-resistant pipes 200 are detachably mounted, such as being fixedly mounted by spot welding in practice, that is, the bottom wall of the edge sealing plate 201 of the outer wall of the upper wear-resistant pipe 200 is fixed to the top wall of the lower wear-resistant pipe 200 by spot welding. From top to bottom, the diameter of the multi-layer wear-resistant tube 200 increases successively, and the top of the lower wear-resistant tube 200 closes the gap between the two inner walls through the upper edge sealing plate 201, so that the inner wall of the top wear-resistant tube 200 is first subjected to impact, while the lower wear-resistant tube 200 is rarely subjected to impact and wear. When the upper wear-resistant tube 200 is damaged, the upper wear-resistant tube 200 can be removed and the lower wear-resistant tube 200 can be directly used for continued use without the need for cumbersome repeated installation processes, and the operation is faster. Figure 1 As shown in FIG. 2 , a three-layer wear-resistant pipe 200 may be used.

[0038] In practice, it is preferred that the multiple layers of wear-resistant pipes 200 are nested and installed in sequence, and the bottom end of the upper layer of wear-resistant pipe 200 extends downward and is embedded in the lower layer of wear-resistant pipe 200. In this way, the edge sealing plate 201 can be arranged in the middle area of ​​the wear-resistant pipe 200, which is more conducive to improving the position matching stability between the multiple layers of wear-resistant pipes 200 and further reducing the wear of the lower layer of wear-resistant pipe 200 caused by the material.

[0039] In order to improve the overall structural strength of the wear-resistant pipe 200 and ensure its service life, further, multiple groups of reinforcing ribs 202 are connected between the outer wall of the wear-resistant pipe 200 and the upper surface of the edge sealing plate 201. The multiple groups of reinforcing ribs 202 are evenly spaced and distributed along the circumference of the wear-resistant pipe 200. Specifically, triangular reinforcing ribs can be used. In practice, the wear-resistant pipe 200, the edge sealing plate 201 and the reinforcing ribs 202 are preferably steel structures.

[0040] In order to ensure the timely discharge of materials in the silo 100 and avoid excessive accumulation of materials in the material accumulation dead corner area 102, further, the total extension height of the multi-layer wear-resistant pipe 200 inside the silo 100 does not exceed 1 meter.

[0041] In practice, the wear-resistant pipe 200 in contact with the bottom plate 103 can be optionally extended downward at its bottom end without exceeding the bottom surface of the bottom plate 103, and is preferably kept horizontal and flush, so that the integrity and aesthetics of the silo 100 are still maintained in the overall appearance, and the protection of the discharge port on the bottom plate 103 can be fully guaranteed.

[0042] The above is a schematic description of the present invention and its implementation methods, which is not restrictive and is only one of the implementation methods of the present invention, and is not actually limited to this. Therefore, if ordinary technicians in this field are inspired by it and design structural methods and embodiments similar to the technical solution without creativity without departing from the purpose of the present invention, they should all fall within the protection scope of the present invention.
