Description

Technical Field

[0001] This application relates to the field of mineral storage technology, and in particular to a tungsten concentrate storage silo. Background Technology

[0002] In practical applications, the inventors discovered that in the tungsten concentrate storage bins of the relevant technologies, when ore is continuously added to the storage bins from the same location, the ore tends to accumulate in the storage cavity without intervention, forming conical peaks. This results in the surrounding area of ​​the storage bin not being fully utilized, leading to frequent reloading of the bins, which severely restricts production efficiency. Furthermore, the uneven distribution of ore within the bins can cause discharge obstruction at the outlet, affecting the efficiency of tungsten concentrate transportation. Utility Model Content

[0003] The purpose of this application is to provide a tungsten concentrate storage bin to improve the technical problems in related technologies, such as the inability to fully utilize the storage chamber in the storage bin and the easy occurrence of poor discharge at the outlet due to uneven distribution of ore in the bin.

[0004] To achieve the above objectives, embodiments of this application provide a tungsten concentrate storage silo, comprising:

[0005] support;

[0006] A hopper body having a storage cavity with an opening at the top, the hopper body being mounted on the support;

[0007] A cover plate is provided at the opening of the storage cavity, and the cover plate is provided with a material inlet.

[0008] The material dispensing component includes:

[0009] An installation plate is provided at the feed inlet, and the installation plate has a feed inlet that communicates with the storage cavity;

[0010] The connecting rod and the material distribution baffle are provided. One end of the connecting rod is connected to the mounting plate, and the other end extends into the storage cavity and is connected to the material distribution baffle. The projection outline of the inlet along the axial direction at least partially overlaps with the material distribution baffle.

[0011] In some embodiments, the projected profile of the feed inlet along the central axis is located within the projected profile of the distribution baffle along the central axis.

[0012] In some embodiments, a plurality of the connecting rods are arranged circumferentially along the feed inlet, and the end of each connecting rod away from the mounting plate is connected to the material distribution baffle.

[0013] In some embodiments, the material distribution baffle has a convex surface on one side, and the convex surface faces the feed inlet.

[0014] In some embodiments, the convex surface is a spherical surface, and the central axis of the feed inlet passes through the center of the sphere on which the convex surface is located.

[0015] In some embodiments, the material distribution baffle is provided with at least one feed through hole extending from the outer convex surface to the opposite surface.

[0016] In some embodiments, the feed through hole and the feed inlet are coaxially arranged, and the projected outline of the feed through hole along the axial direction is within the projected outline of the feed inlet along the axial direction.

[0017] In some embodiments, at least one impeller is provided in the storage chamber, and the two ends of the impeller's shaft are rotatably connected to two opposite inner sidewalls of the storage chamber.

[0018] In some embodiments, a discharge pipe communicating with the storage chamber is provided on the bottom end face of the hopper body, and a screen is provided in the storage chamber near the connection of the discharge pipe.

[0019] In some embodiments, the cover surface near the dispensing assembly is provided with a selectively openable inspection cover.

[0020] The above-described technical solutions in the embodiments of this application have at least the following technical effects or advantages:

[0021] 1) The tungsten concentrate storage silo of this application has a feed inlet installed through a cover plate. A distribution component is installed at the feed inlet. The distribution component includes an installation plate with the feed inlet and a distribution baffle installed at the bottom of the feed inlet on the installation plate via a connecting rod. The distribution baffle has a spherical convex surface facing the feed inlet. The central axis of the feed inlet passes through the center of the spherical surface on which the convex surface is located. In this way, when the tungsten concentrate enters the material cavity of the storage silo, it first falls onto the distribution baffle. The distribution baffle causes the tungsten concentrate to spread to the sides of the material cavity. At the same time, setting the distribution baffle to a spherical convex surface facing the feed inlet can make the tungsten concentrate distribution more uniform, improve the utilization rate of the storage space in the storage silo, and improve the tungsten concentrate conveying efficiency because the ore distribution in the tungsten concentrate silo is more uniform.

The terminology used herein in the specification of this application is for the purpose of describing particular embodiments only and is not intended to be limiting of the application. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0044] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments.

[0045] Please see Figure 1This embodiment provides a tungsten concentrate storage silo 10. The storage silo 10 includes a support 100, a silo body 200, a cover plate 300, and a material distribution assembly 400. For ease of description of the structure of the storage silo 10, the direction along the height of the storage silo 10 is defined as the first direction A. The silo body 200 is disposed on the support 100 along the first direction A, and the cover plate 300 is disposed on the silo body 200 along the first direction A. The support 100 may include support beams 110 and crossbeams 120. The support beams 110 and crossbeams 120 are welded to form a frame structure to provide more stable support for the silo body 200. For example, six support beams 110 can be divided into two groups, each group consisting of three support beams 110 spaced apart on the same plane. The two groups of support beams 110 are spaced parallel to each other. At the same time, the crossbeams 120 are fixedly connected to each support beam 110 along the perpendicular first direction A, thereby forming a space area above the support 100 where the silo body 200 can be placed and fixed.

[0046] Optionally, reinforcing ribs can be provided at the connection between the crossbeam 120 and the support beam 110 to improve the structural stability of the connection. A support inclined plate 130 can be provided at the contact position between the crossbeam 120 and the silo body 200. The support inclined plate 130 is in close contact with the outer wall surface of the silo body 200. It should be understood that the support beam 110 and the crossbeam 120 can also be set into other structural shapes, provided that they can provide fixed support for the silo body 200. The specific shape can be adapted according to actual needs.

[0047] Optionally, the height of the support beam 110 needs to ensure that there is a certain height difference between the lowest point of the silo body 200 and the ground after the silo body 200 is installed. This facilitates the connection and arrangement of the discharge pipe 250 at the bottom of the silo body 200. To further ensure the stability of the storage silo 10 after placement, a pad can be set at the end of the support beam 110 that contacts the ground. The pad can have through holes or bolt holes for fixing with screws or bolts. The connection between the crossbeam 120 and the support beam 110 can be welded or bolted, and there are no restrictions on this.

[0048] Please see Figure 2 and Figure 3The silo body 200 can be composed of two storage cavities 210 with openings at the top. The two storage cavities 210 are spaced apart, and each is individually connected to a discharge pipe at its bottom. The cross-sectional area of ​​the lower part of the two storage cavities 210, perpendicular to the first direction A, gradually decreases from top to bottom, forming a conical structure at the bottom of the silo body 200. This facilitates the flow of tungsten concentrate from the storage cavities 210. For ease of description of the silo body 200 structure, the direction along which the two storage cavities 210 are arranged side-by-side is defined as the second direction B. To strengthen the internal structure of the silo body 200, in... Multiple first reinforcing beams 211 can be installed inside the storage chamber 210 along the second direction B. The two ends of the multiple first reinforcing beams 211 are respectively connected to the inner walls of both sides of the storage chamber 210. Of course, in order to facilitate the transfer and installation of the storage hopper 10, first lifting lugs 240 are installed on the four side walls of the hopper body 200. In addition, a discharge pipe 250 communicating with the storage chamber 210 is installed at the bottom of the hopper body 200. An existing electric gate valve 251 can be installed on the discharge pipe 250 to control the outflow of tungsten concentrate. The specific control principle of the electric gate valve 251 will not be elaborated here.

[0049] It should be noted that one or three storage cavities 210 can be provided. In addition, since the storage silo 10 usually needs to be inspected during daily operation, some wires or other debris may fall into the silo body 200 due to negligence during the actual inspection, which may easily cause the discharge pipe 250 to be blocked. By setting a screen 220 at the bottom of the storage cavity 210, debris can be prevented from entering the discharge pipe 250, which may cause blockage of the discharge pipe 250 or obstruction of discharge. Of course, the size of the mesh in the screen 220 can be selected according to actual needs.

[0050] Please see Figure 4 and Figure 5 A cover plate 300 is installed over the opening above the storage chamber 210 to form a relatively sealed chamber. The cover plate 300 includes a cover plate body 310. A second reinforcing beam 311 can be provided on the bottom surface of the cover plate body 310. Two sets of feeding installation ports 312 and maintenance installation ports 313 can be opened at intervals on the surface of the cover plate body 310. Each set of feeding installation ports 312 and maintenance installation ports 313 are connected to a storage chamber 210. A material distribution component 400 is provided in the feeding installation port 312, and a maintenance cover 320 is provided in the maintenance installation port 313. The material distribution component 400 completely covers the feeding installation port 312, and the maintenance cover 320 completely covers the material distribution component 400.

[0051] Thus, the installation port 313 and the inspection cover 320 facilitate maintenance personnel to carry out maintenance work inside the storage silo 10. The installation port 312 facilitates the installation and fixation of the material distribution component 400. The material distribution component 400 can disperse the tungsten concentrate during the process of adding it into the storage chamber 210, so as to achieve a more uniform distribution of the tungsten concentrate in the storage chamber 210.

[0052] Optionally, flanges can be provided around the inspection and installation port 313, and the inspection cover 320 can be fastened above the inspection and installation port 313. The material distribution component 400 can be fixed to the feed installation port 312 by bolts. In order to facilitate the installation and transfer of the cover plate 300, multiple second lifting lugs 330 can be provided on the surface of the cover plate 300 near the edge.

[0053] Please see Figures 6 to 8 For the material distribution assembly 400, the material distribution assembly 400 includes a mounting plate 410, a connecting rod 420 and a material distribution baffle 430. The mounting plate 410 is disposed at the material inlet 312 and has a material inlet 411 communicating with the material storage chamber 210. One end of the connecting rod 420 is connected to the mounting plate 410, and the other end extends into the material storage chamber 210 and connects to the material distribution baffle 430. The projection outline of the material inlet 411 along the axial direction at least partially overlaps with the material distribution baffle 430.

[0054] Optionally, a first screw hole group 412 and a second screw hole group 413 are provided at intervals around the feed inlet 411 on the surface of the mounting plate 410. The first screw hole group 412 is close to the perimeter of the mounting plate 410 for fixed connection with the cover plate 300, and the second screw hole group 413 is provided near the feed inlet 411 for connection and fixation of one end of the connecting rod 420. Multiple screw holes can be provided in the first screw hole group 412 and the second screw hole group 413, and the specific design can be selectively designed according to actual needs.

[0055] Optionally, multiple connecting rods 420 are arranged circumferentially along the feed inlet 411, and the other end of each connecting rod 420 is connected to the surface of the material distribution baffle 430. Specifically, three, four or five connecting rods 420 can be set, and multiple connecting rods 420 are arranged at intervals. The arrangement of multiple connecting rods 420 ensures the structural stability of the material distribution baffle 430 after connection.

[0056] In some embodiments, a convex surface 431 is provided on one side of the distribution baffle 430, facing the feed inlet 411. The convex surface 431 is a spherical surface, and the central axis of the feed inlet 411 passes through the center of the sphere on which the convex surface 431 is located. The projected outline of the feed inlet 411 along the central axis direction is within the projected outline of the distribution baffle 430 along the central axis direction. The convex surface 431 is provided, and the outline size of the distribution baffle 430 is set to be larger than the outline size of the feed inlet 411.

[0057] With this configuration, when the tungsten concentrate enters the storage chamber 210 of the storage silo 200, it first falls onto the distribution baffle 430. The distribution baffle 430 causes the tungsten concentrate to spread outwards from the storage chamber. At the same time, by setting the distribution baffle 430 to a spherical convex surface 431 facing the feed inlet, the tungsten concentrate can be distributed more evenly, improving the utilization rate of the storage space in the storage silo. Furthermore, because the ore is more evenly distributed in the silo, the discharge from the storage silo is smoother, improving the tungsten concentrate conveying efficiency.

[0058] Optionally, the surface of the distribution baffle 430 opposite to the convex surface 431 can be provided with a concave surface 432, that is, the concave surface 432 and the convex surface 431 have the same concave-convex direction. In addition, the distribution baffle 430 is provided with at least one feed through hole 433 that extends from the convex surface 431 to the opposite concave surface 432. The feed through hole 433 and the feed inlet 411 are coaxially arranged. The projection outline of the feed through hole 433 along the axial direction is within the projection outline of the feed inlet 411 along the axial direction. Through the feed through hole 432 that extends through the distribution baffle 430, when the tungsten concentrate falls onto the upper surface of the distribution baffle 430, part of the tungsten concentrate falls from the feed through hole 432 into the material cavity area directly below the distribution baffle 430, further ensuring the uniformity of the distribution of tungsten concentrate in the material cavity.

[0059] Please see Figure 9 When the material distribution component 400 is positioned on one side of the storage chamber 210, in order to further ensure a more uniform distribution of tungsten concentrate in the opposite side of the storage chamber 210, at least one impeller 230 can be set in the storage chamber 210 along the second direction B. The two ends of the impeller 230 can be rotatably connected to the inner wall of the storage chamber 210 respectively. The impeller 230 and the material distribution component 400 can be staggered. When some tungsten concentrate falls onto the impeller 230, the impeller 230 can further disperse the tungsten concentrate to the surrounding area of ​​the storage chamber 210, thereby making the concentrate distribution more uniform and improving the utilization rate of the silo.

[0060] Optionally, for the rotatable connection between the impeller 230 and the inner wall of the storage chamber 210, bushings that cooperate with the rotating shafts at both ends of the impeller 230 can be provided on the two inner walls of the storage chamber 210. In order to reduce the friction during rotation, bearings can be provided on the bushings, and to prevent tungsten concentrate from entering at the connection, sealing rings can be provided. It should be understood that the bearings and sealing rings are conventional settings, and the specific design can be made according to actual needs.
