Description

Technical Field

[0001] This utility model belongs to the technical field of mineral bin components, and in particular relates to a mineral bin component that prevents mineral powder from solidifying. Background Technology

[0002] In the mining and beneficiation processes of metal and non-metal mines, ore bins are key facilities for the temporary storage and transfer of ore, and their stability and effective volume are directly related to production efficiency and cost control.

[0003] However, in high-altitude and cold-weather mines, winter temperatures often drop below -20°C. During the mining, crushing, and transportation of ore, the moisture content increases (usually by 5% to 15%) due to contact with water (such as groundwater, snowfall, or process water). The fine particles formed after ore crushing (mostly less than 30 mm in diameter) have an increased specific surface area, which further exacerbates the adsorption and retention of moisture.

[0004] When this type of ore enters the ore bin, the low temperature causes moisture to freeze, leading to the formation of ice crystals that bind the ore particles together. Simultaneously, the bottom of the bin, subjected to continuous pressure from the upper layer of ore, causes the frozen ore to gradually compact under repeated freeze-thaw cycles, eventually forming an inverted cone-shaped solidified body around the bottom discharge port. This phenomenon not only results in a loss of effective bin volume (typically 20%–40%), but also leads to blockages at the discharge port and impeded ore discharge, forcing frequent production interruptions for manual clearing, significantly increasing safety risks and maintenance costs.

[0005] To address the aforementioned issues, this application proposes a mineral bin component designed to prevent mineral powder from solidifying. Utility Model Content

[0006] The purpose of this invention is to provide a mineral bin component that prevents mineral powder from solidifying, thereby solving the problems mentioned in the background art.

[0007] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0008] This utility model is a mineral bin component for preventing mineral powder from solidifying, including a mineral bin and a bottom plate, with two rows of discharge ports inside the bottom plate;

[0009] The discharge pipe consists of a vertical pipe and an inclined pipe, and is connected to the discharge pipe below the base plate;

[0010] A sleeve shaft is rotatably mounted inside the vertical tube, and a material passage is mounted on the outside of the sleeve shaft;

[0011] The top of the sleeve shaft is provided with a support, and a stirring part is installed on the outside of the support. The stirring part has two usage states: vertical and horizontal.

[0012] Furthermore, a fixed frame is provided below the vertical tube, and an external gear that is detachably and fixedly connected to the sleeve shaft is rotatably installed at the bottom. An internal toothed belt that drives the adjacent external gear to rotate is rotatably installed in the lower outer ring area of ​​the fixed frame.

[0013] Furthermore, a sealing part with a sleeve shaft is installed at the bottom of the vertical tube.

[0014] Furthermore, a connecting rod is fixedly connected to the lower end of the support, passing through the inside of the sleeve shaft, and the lower end is fixed by bolts.

[0015] Furthermore, one end of the stirring part is fixedly connected to a ring sleeve, which is rotatably installed in a side groove inside the side wall of the support, and a support plate extends from the end of the ring sleeve away from the stirring part.

[0016] Furthermore, the support has an air bladder inside, which is fixedly installed at the top inside the support.

[0017] Furthermore, a limit ring is bolted to the lower end of the support to clamp the support plate.

[0018] This utility model has the following beneficial effects:

[0019] This invention integrates a mixing unit with a built-in feeding port. During feeding, the feeding port clears blockages and prevents clogging. Simultaneously, the mixing unit breaks up agglomerated mineral powder. The two functions complement each other, causing the bottom of the mineral powder to collapse and the upper mineral powder to fall downwards, thus ensuring the effective volume of the ore bin.

[0020] The stirring part of this invention can change from vertical to horizontal under the action of the sleeve shaft, and can be installed inside the ore bin through the bottom of the feeding port. Moreover, the installation of this mechanism will not affect the original structure of the ore bin. It can be directly installed on the bottom of the ore bin and is suitable for use in different models of ore bins, thus reducing their maintenance costs.

[0021] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0039] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0040] In the description of this utility model, it should be understood that the terms "opening", "upper", "lower", "thickness", "top", "middle", "length", "inner", "around" and other terms indicating orientation or positional relationship are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.

[0041] Please see Figure 1-7 As shown, this utility model is a mineral bin assembly for preventing mineral powder from solidifying, including a mineral bin 1 and a bottom plate 110, with two rows of discharge ports 111 inside the bottom plate 110;

[0042] The discharge pipe 210 consists of a vertical pipe and an inclined pipe. The vertical pipe is connected to the discharge pipe below the base plate 110. The discharge pipe 210 directly replaces the original cover.

[0043] The vertical tube is equipped with a rotating sleeve 230 inside, and a material passage 231 is installed on the outside of the sleeve 230. It can be a mechanism for clearing blockages in mineral powder, such as a spiral blade, a stirring plate, or a stirring rod.

[0044] The top of the sleeve shaft 230 is provided with a support 250, and a stirring part 240 is installed on the outside of the support 250. The stirring part 240 has two usage states: vertical and horizontal. The stirring part 240 can be a stirring rod, stirring plate, or other mechanism that can break up agglomerated mineral powder. When used horizontally, its length can extend into the interior of the adjacent feed port 111, covering a larger breaking up range.

[0045] Preferably, a fixed frame 220 is provided below the vertical tube, and an external gear 222 is rotatably mounted at the bottom and detachably fixedly connected to the sleeve shaft 230. An internal toothed belt 221 that drives the adjacent external gears 222 to rotate is rotatably mounted on the lower outer ring area of ​​the fixed frame 220. The internal toothed belt 221 meshes with each external gear 222. Only one external gear 222 needs to be rotated by the rotating motor to drive all external gears 222 to rotate.

[0046] Preferably, a sealing part 211 through which the sleeve shaft 230 is installed is installed at the bottom of the vertical tube, so that the sleeve shaft 211 can be kept in a stable rotational state and avoid blockage and jamming.

[0047] Preferably, a connecting rod 251 is fixedly connected to the lower end of the support 250, which passes through the inside of the sleeve shaft 230. The lower end is fixed by bolts. The rotation of the sleeve shaft 230 can drive the connecting rod 251 to rotate, and at the same time drive the stirring part 240 on its outer side to rotate, thereby breaking up the clumps of mineral powder.

[0048] Preferably, one end of the stirring part 240 is fixedly connected to a ring 241, and a side groove 252 is rotatably installed in the side wall of the support 250. The end of the ring 241 away from the stirring part 240 extends to a support plate 242. The side groove 252 is a bottom-opening groove that runs through the left and right sides, and the support plate 242 extends into the cavity of the support 250.

[0049] Preferably, the support 250 has an air bladder 254 inside, which is fixedly installed on the top inside the support 250. The air bladder 254 is initially in a relaxed state, so the right side is pushed upward by the support plate 242. When the air bladder 254 is pressed by the bushing 230, the space contraction causes it to change to a taut state, thereby driving the support plate 242 to rotate downward, which in turn drives the stirring part 240 to rotate upward to a horizontal state.

[0050] Preferably, a limit ring 253 is bolted to the lower end of the support 250, which is combined with the support 250 to clamp the support plate 242, so that the stirring part 240 is kept in a lateral state to prevent shaking.

[0051] Furthermore, the mixing unit 240 can be configured as an electric telescopic rod as needed, with its fixed end fixedly connected to the support 250. During installation, the electric telescopic rod is in a retracted state. The movable end of the electric telescopic rod has a pointed structure, which can be extended into the interior of the ore bin after entering the feeding port. Using this telescopic structure, the range of ore body agitation gradually increases from small to large, achieving a gradual dispersing method from the inside out. This can reduce power consumption and avoid motor damage caused by load, thereby avoiding excessive resistance from affecting the dispersing effect.

[0052] It is understood that this utility model can be directly installed inside the discharge port 111 of a traditional ore bin 1, so that during the discharge operation, the rotating and unblocking method of ore powder will simultaneously drive the stirring component to break up the bottom area of ​​the clump of ore powder, causing it to collapse and thus causing the ore powder above to fall downward, thereby promoting the discharge and increasing the effective volume of the ore bin 1.

[0053] A specific application of the operation process in this embodiment is as follows: First, the connecting rod 251 is inserted into the inside of the discharge port 111, so that the bottom of the drooping stirring part 240 is higher than the discharge port 111. Then, the sleeve shaft 230 is sleeved on the outside of the connecting rod 251, and its upper end is pressed against the air bag 254. At this time, the air bag 254 changes from a relaxed state to a taut state, thereby pressing down the support plate 242 and causing the stirring part 240 to rotate and rise around the ring 241 as the axis, and finally placed above the base plate 110. At this time, the air bag 254 and the limiting ring 253 clamp the support plate 242, so that the stirring part 240 is fixed in a horizontal state. Then... The sleeve shaft 230 is connected and fixed to the connecting rod 251 by bolts, and the vertical pipe body of the discharge pipe 210 is fixed to the protruding pipe under the discharge port 111. At this time, the bottom of the feeding part 231 is inserted into the sealing part 211 and connected and fixed to the bottom of the fixing frame 220 232. Finally, the rotary motor drives one 232 to rotate, and then drives all 232 to rotate through the internal toothed belt 221. This drives the sleeve shaft 230 inside each discharge port 111 to rotate, thereby driving the feeding part 231 to clear the mineral powder and prevent blockage. At the same time, it drives the stirring part 240 to rotate and break up the bottom of the agglomerated mineral powder, causing it to collapse and causing the mineral powder above to fall downward.
