Description

Technical Field

[0001] This utility model relates to the field of phosphate rock production technology, and in particular to an automatic phosphate rock feeding mechanism. Background Technology

[0002] Phosphate rock is a general term for economically usable phosphate minerals. It is an important chemical mineral raw material that can be used to produce phosphate fertilizers, as well as to manufacture yellow phosphorus, phosphoric acid, phosphides and other phosphates for use in pharmaceutical, food, match, dye, sugar, ceramic and other industrial sectors.

[0003] In existing technologies, mined yellow phosphorus ore is usually stored in warehouses and exposed to the air. However, when the phosphorus in the phosphate ore is exposed to the air, some of the phosphate ore will undergo an oxidation reaction with oxygen to produce oxides such as phosphorus trioxide. These oxides have strong water absorption properties and react with water to produce phosphoric acid, causing the surface of the phosphate ore to deliquesce, form water of crystallization or dissolve, and aggravate the agglomeration phenomenon on the outer surface of the ore powder. Therefore, in the subsequent processing and production of phosphate ore, the damp and agglomerated phosphate ore powder is prone to clogging the discharge port when unloading from the storage silo to the conveyor, causing many inconveniences to production. Utility Model Content

[0004] The purpose of this invention is to solve the problem in the prior art that damp and clump-forming phosphate rock powder easily clogs the discharge port during the unloading process from the storage silo to the conveyor, and to propose an automatic phosphate rock feeding mechanism.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] An automatic phosphate ore feeding mechanism includes a vertically penetrating working cylinder. A rotating shaft is rotatably connected inside the working cylinder. A flow divider plate is fixedly connected inside the working cylinder. An extrusion member is mounted on the rotating shaft. The top of the extrusion member is in contact with the bottom of the flow divider plate, forming an extrusion cavity between the extrusion member and the working cylinder. A loosening member is mounted at the bottom of the working cylinder. The axis of the loosening member is perpendicular to the axis of the rotating shaft. When the rotating shaft rotates, the radial displacement of the extrusion member changes the volume of the extrusion cavity, and the loosening member reciprocates along its own axis.

[0007] To facilitate the extrusion of phosphate rock, preferably, the extrusion component includes an extrusion plate fixedly connected to a rotating shaft, the bottom of the diverter plate is provided with an arc-shaped groove, and the top of the extrusion plate is in contact with the inner wall of the arc-shaped groove.

[0008] To further improve the extrusion effect of phosphate ore, protrusions are fixedly connected to the extrusion plate and the inner wall of the working cylinder.

[0009] To facilitate the rotation of the shaft, preferably, a telescopic component is fixedly connected to the outer wall of the working cylinder, one end of the shaft extends to the outside of the working cylinder and is fixedly connected to a gear, and the output end of the telescopic component is provided with a rack, the gear meshing with the rack.

[0010] To facilitate the movement of the lifting plate, the loosening component further includes a loosening column, the lifting plate is slidably connected inside the working cylinder cavity, the loosening column is fixedly connected to the lifting plate, and the lifting plate is fixedly connected to the bottom of the rack via a connecting rod.

[0011] To facilitate the limited movement of the lifting plate, a sliding groove is further provided on the working cylinder, and the outer wall of the lifting plate fits into the sliding groove.

[0012] Compared with the prior art, this utility model provides an automatic phosphate ore feeding mechanism, which has the following beneficial effects:

[0013] 1. The automatic phosphate ore feeding mechanism drives the extrusion plate to rotate via a rotating shaft. The extrusion plate can change the volume of the extrusion cavity by radial displacement. By changing the volume, mechanical extrusion is applied to the agglomerated phosphate ore, breaking the surface solidification layer. The ore powder is then pre-crushed and flows out through the feed port of the working cylinder, reducing the possibility of blockage.

[0014] 2. This automatic phosphate ore feeding mechanism can loosen the ore powder in the discharge channel a second time through the lifting and moving loosening column, penetrating the ore powder accumulation layer in the discharge channel and achieving the effect of loosening deep materials.

[0015] 3. The automatic phosphate ore feeding mechanism forms a dynamic seal by fitting the extrusion component with the diverter plate. At the same time, it can divert the phosphate ore entering the working cylinder, moving it to both sides of the working cylinder to avoid excessive local accumulation in the extrusion cavity.

[0016] The parts not mentioned in this device are the same as or can be implemented using existing technology. This utility model can change the volume of the extrusion cavity by radial displacement of the extrusion plate, and then apply mechanical extrusion to the agglomerated phosphate rock by changing the volume, thereby destroying the surface solidification layer, so that the mineral powder is pre-crushed and then flows out through the feed port of the working cylinder, reducing the blockage. At the same time, it can also use the loosening column to loosen the mineral powder in the discharge channel for a second time, penetrate the mineral powder accumulation layer in the discharge channel, and achieve the effect of loosening deep materials.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0024] Phosphate rock refers to the general term for economically usable phosphate minerals. It is an important chemical mineral raw material. In the current technology, mined yellow phosphorus ore is usually placed in warehouses and exposed to the air. However, when the phosphorus element in the phosphate ore is exposed to the air, some of the phosphate ore will react with oxygen to form oxides such as phosphorus trioxide. These oxides have strong water absorption and react with water to form phosphoric acid, causing the surface of the phosphate ore to deliquesce, form crystal water or dissolve, and aggravate the agglomeration phenomenon on the outer surface of the mineral powder. In order to facilitate the convenient feeding of yellow phosphorus ore, it is transported into the working cylinder 1 for feeding.

[0025] Example:

[0026] Reference Figures 1-4An automatic phosphate ore feeding mechanism includes a rotating shaft 2 rotatably connected inside a working cylinder 1, and a flow divider 4 fixedly connected inside the working cylinder 1. An extrusion component is mounted on the rotating shaft 2, with its top fitting against the bottom of the flow divider 4, forming an extrusion cavity between the extrusion component and the working cylinder 1. The working cylinder 1 serves as the main container for phosphate powder, containing the fixed flow divider 4 and the rotatable rotating shaft 2. When the rotating shaft 2 rotates, it causes the extrusion component to undergo radial displacement. The fit between the extrusion component and the flow divider 4 creates a dynamic seal, simultaneously diverting the phosphate ore entering the working cylinder 1 to both sides, preventing excessive local accumulation within the extrusion cavity. The radial displacement of the extrusion component changes the extrusion... The volume of the cavity is adjusted to mechanically compress the agglomerated phosphate rock, breaking down the surface solidification layer. This allows the ore powder to be pre-crushed before flowing out through the discharge port of the working cylinder 1, reducing clogging. In addition, a loosening element is provided at the bottom of the working cylinder 1. The axis of the loosening element is perpendicular to the axis of the rotating shaft 2. When the rotating shaft 2 rotates, the radial displacement of the extruder changes the volume of the extrusion cavity, and the loosening element moves back and forth along its own axis. When the ore powder is pre-crushed and flows out through the discharge port of the working cylinder 1, the loosening element at its outlet can loosen the ore powder in the discharge channel a second time and penetrate the ore powder accumulation layer in the discharge channel, achieving the effect of loosening deep materials.

[0027] In the above scheme, when the phosphorus element in the phosphate rock is exposed to air, some of the phosphate rock will undergo an oxidation reaction with oxygen. These oxides have strong water absorption and react with water to form phosphoric acid, causing the outer surface of the mineral powder to clump. In order to facilitate the convenient feeding of yellow phosphorus ore, it will be transported into the working cylinder 1. During the feeding process, a dynamic seal is formed by the fit between the extruder and the diversion plate 4. At the same time, the phosphate ore entering the working cylinder 1 can be diverted to both sides of the working cylinder 1 to avoid excessive local accumulation. When the rotating shaft 2 rotates, the radial displacement of the extruder changes the volume of the extrusion cavity. In turn, the change in volume applies mechanical extrusion to the clumped phosphate ore, destroying the surface solidification layer. The mineral powder is pre-crushed and then flows out through the feed port of the working cylinder 1, reducing the blockage. At the same time, the loosening part set at the outlet of the working cylinder 1 can loosen the mineral powder in the discharge channel for a second time and penetrate the mineral powder accumulation layer in the discharge channel to achieve the effect of deep material loosening.

[0028] The extrusion component includes an extrusion plate 3 fixedly connected to the rotating shaft 2. The bottom of the diverter plate 4 is provided with an arc-shaped groove. The top of the extrusion plate 3 is in contact with the inner wall of the arc-shaped groove. The material of the extrusion plate 3 is wear-resistant stainless steel, and the surface is laser-coated with tungsten carbide coating to enhance wear resistance. The extrusion plate 3 and the arc-shaped groove can form a dynamic sealing effect.

[0029] A protrusion 7 is fixedly connected to the inner wall of the extrusion plate 3 and the working cylinder 1. During the rotation of the extrusion plate 3, the protrusion 7 can be driven to cooperate with the protrusion 7 on the inner wall of the working cylinder 1 to crush the phosphate ore.

[0030] In order to drive the rotating shaft 2 to rotate, a telescopic component 8 is fixedly connected to the outer wall of the working cylinder 1. The telescopic component 8 can be a cylinder or an electric telescopic rod. A gear 9 is fixedly connected to one end of the rotating shaft 2 to the outside of the working cylinder 1. A rack 10 is provided at the output end of the telescopic component 8. The gear 9 meshes with the rack 10. The telescopic component 8 can drive the rack 10 to move, thereby driving the gear 9 to reciprocate and rotate, so that it drives the rotating shaft 2 to reciprocate.

[0031] The aforementioned loosening component includes a loosening column 6. A lifting plate 5 is slidably connected inside the cavity of the working cylinder 1. The loosening column 6 is fixedly connected to the lifting plate 5. The lifting plate 5 is fixedly connected to the bottom of the rack 10 via a connecting rod. A sliding groove is provided on the working cylinder 1. The outer wall of the lifting plate 5 fits into the sliding groove. When the telescopic component 8 can drive the rack 10 to move back and forth, it can drive the lifting plate 5 to move back and forth, thereby enabling it to drive the loosening column 6 to move synchronously, achieving the effect of lifting and loosening.

[0032] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
