Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of mine ore bins, and specifically relates to a mine ore bin whose ore discharge port is not easily blocked. Background Art
[0002] In the mining industry, underground mine silos are used to temporarily store mined minerals and serve as transfer devices to transfer minerals to lifting devices for transporting the mined minerals. Traditional underground mine silos usually have a reinforced concrete casting layer on the inner surface of the mine, which forms the inner wall of the mine silo. The reinforced concrete casting layer is in direct contact with the material during use. However, this type of structure is prone to collapse during use due to its low structural strength.
[0003] Therefore, in the prior art, the ore bin body is reinforced by using an anchor bolt anchoring layer, and a steel plate layer is provided corresponding to the anchor bolt anchoring layer. When in use, the surface of the steel plate layer is in direct contact with the material. This method improves the structural stability of the mine bin. However, there are the following problems: when the mineral contains a high amount of water, it is mostly powdery after blasting, and the looseness of the powdery material is very poor. In the rainy season, due to the increase in humidity in the environment where the ore bin is located, the ore is very easy to adhere to the surface of the manganese steel plate, causing unsmooth discharge. Unsmooth discharge and blockage of the discharge port will cause discontinuous ore feeding or even shutdown, which seriously affects the production efficiency of the ore dressing plant. Utility Model Content
[0004] In order to overcome the problems existing in the background technology, the utility model provides a mine ore bin whose discharge port is not easily blocked by materials. By constructing a dehumidification channel, the side walls of the ore bin body are not easily adhered to by materials, thereby reducing the frequency of blockage at the discharge port and thereby improving the production efficiency of the ore dressing plant.
[0005] To achieve the above purpose, the utility model is implemented through the following technical solutions:
[0006] A mine ore bin with a discharge port that is not easily blocked, comprises a ore bin body, and a discharge port is arranged at the bottom of the ore bin body; an anchoring layer is anchored on the inner side wall of the ore bin body, and a supporting and fixing part is fixedly connected to the other end of the anchoring layer; a steel plate layer is welded to the end face of the supporting and fixing part facing away from the anchoring layer, and the steel plate layer is fully spread on the surface of the supporting and fixing part; a concrete layer is poured and filled in the gap between the supporting and fixing part and the ore bin body; the supporting and fixing part is composed of a plurality of channel steels arranged longitudinally, and the open end of the channel steel faces one side of the steel plate layer; a dehumidification channel with open ends is enclosed between the channel steel and the steel plate layer, the bottom end of the dehumidification channel extends to near the discharge port, and the top end of the dehumidification channel extends to the top of the ore bin body.
[0007] Preferably, the anchoring layer comprises an inverted wedge anchor rod and a steel mesh, the wedge-shaped end of the inverted wedge anchor rod is anchored on the side wall of the ore bin body, the other end of the inverted wedge anchor rod is welded and fixed on the supporting fixing part, and the steel mesh is bundled on the inverted wedge anchor rod.
[0008] Preferably, the steel plate layer is formed by splicing a plurality of manganese steel plates.
[0009] Beneficial effects of the utility model:
[0010] (1) The utility model transforms the existing ore bin body. On the basis of ensuring the stable support of the anchor layer, the supporting and fixing part and the steel plate layer, a supporting and fixing part composed of a plurality of longitudinally arranged channel steels is selected, and the open end of the channel steel faces one side of the steel plate layer, and a dehumidification channel with open ends is enclosed between the channel steel and the steel plate layer; by constructing the dehumidification channel connected to the external environment, the external environment air can pass smoothly through the dehumidification channel, and in the process of air passing, the moisture in the dehumidification channel is taken away, thereby avoiding the re-moisture of the material due to the excessive humidity of the environment in the ore bin body, and finally making the material more easily adhere to the surface of the steel plate, resulting in poor discharge of the material.
[0011] (2) By adopting the dehumidification channel constructed in the utility model to discharge moisture, the frequency of blockage of the discharge port is greatly reduced, and the frequency of blockage of the discharge port is reduced from an average of 2.6 times per shift before the transformation to 0.5 times, which effectively improves the production efficiency of the ore dressing plant.

[0014] In order to make the purpose, technical solution and beneficial effects of the present invention clearer, the preferred embodiments of the present invention will be described in detail below to facilitate understanding by technicians.
[0015] like Figure 1As shown, a mine ore bin with a discharge port that is not easily blocked includes a ore bin body 1, the ore bin body 1 has a chamber for accommodating materials, and a discharge port 2 is arranged at the bottom of the ore bin body 1; an anchoring layer 3 is anchored on the inner side wall of the ore bin body 1, and a support fixing part 4 is fixedly connected to the other end of the anchoring layer 3; a steel plate layer 5 is welded to the end face of the support fixing part 4 facing away from the anchoring layer 3, and the steel plate layer 5 is fully spread on the surface of the support fixing part 4; a concrete layer 6 is poured and filled in the gap between the support fixing part 4 and the ore bin body 1; the support fixing part 4 is composed of a plurality of channel steels arranged longitudinally, and the open end of the channel steel faces one side of the steel plate layer 5; a dehumidification channel with open ends is enclosed between the channel steel and the steel plate layer 5, the bottom end of the dehumidification channel extends to near the discharge port 2, and the top end of the dehumidification channel extends to the top of the ore bin body 1. The channel steel and the steel plate layer 5 are fixedly connected by welding.
[0016] In the utility model, a dehumidification channel is provided, so that when the humidity of the environment in which the ore bin body 1 is located is relatively high, the external ambient air can pass smoothly through the dehumidification channel. During the passage of the air, the moisture in the dehumidification channel is taken away, thereby preventing the material from getting damp due to excessive humidity in the dehumidification channel, causing the material to adhere to the surface of the steel plate and causing poor discharge of the material.
[0017] The anchoring layer 3 has the function of providing support to the ore bin body 1 on the one hand, and providing support to the support fixing part 4 on the other hand.
[0018] Specifically, the anchoring layer 3 includes an inverted wedge-shaped anchor rod 30 and a steel mesh 31, the wedge-shaped end of the inverted wedge-shaped anchor rod 30 is anchored on the side wall of the ore bin body 1, the other end of the inverted wedge-shaped anchor rod 30 is welded and fixed on the support fixing portion 4, and the steel mesh 31 is tied on the inverted wedge-shaped anchor rod 30. The combination of the inverted wedge-shaped anchor rod 30 and the steel mesh 31 can not only provide better support for the side wall of the ore bin body 1, but also provide better support for the support fixing portion 4.
[0019] Specifically, the steel plate layer 5 is formed by splicing a plurality of steel plates. Preferably, the steel plate is a manganese steel plate. The manganese steel plate is not only high in strength, but also has strong corrosion resistance.
[0020] The working process of this utility model:
[0021] When the ore bin of the utility model is used, firstly, the side wall of the ore bin body is anchored with anchor rods, and at the same time, the steel mesh 31 and the support fixing part 4 are fixed and installed on the anchor rods in sequence, and then the concrete layer 6 is poured and filled in the gap between the support fixing part 4 and the ore bin body 1; finally, the steel plate layer 5 is paved and fixed on the support fixing part 4, and the fully paved steel plate layer 5 after paving and fixing serves as the inner side wall of the new ore bin body, so that when discharging, the ore directly contacts the surface of the steel plate layer 5.
[0022] Since a dehumidification channel is constructed in the utility model, through the setting of the dehumidification channel, when the humidity of the ore bin body is high, the moisture in the dehumidification channel can be taken away by air circulation, thereby preventing more moisture from being conducted to the surface of the steel plate, causing the material to adhere to the surface of the steel plate more easily.
[0023] Finally, it should be noted that the above preferred embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail through the above preferred embodiments, those skilled in the art should understand that various changes can be made in form and details without departing from the scope defined by the claims of the utility model.
