Description

Technical Field

[0001] This utility model belongs to the field of silicon powder processing technology, and in particular relates to a silicon powder processing iron removal device. Background Technology

[0002] Silicon powder is an ultrafine powdery byproduct collected through the flue during the smelting of high-purity silicon or ferrosilicon alloys in industrial electric furnaces. It can be used in high-performance concrete, refractory materials, building materials, the chemical industry, and emerging fields. During the smelting of ferrosilicon or industrial silicon, erosion of the furnace lining and impurities in the raw materials can lead to the presence of iron and iron oxides (such as Fe2O3) and magnetic impurities in the collected silicon powder. These impurities reduce the purity, material properties, and appearance of the product. Therefore, it is necessary to use an iron removal device to treat the silicon powder, which is a key step in the deep processing of silicon powder and the enhancement of product added value.

[0003] A search revealed CN223197548U, filed on August 14, 2024, which discloses an iron removal device for silicon powder processing. The device includes: a housing with a processing chamber and a secondary processing chamber located on both sides inside; a partition plate disposed on the housing; an iron removal mechanism disposed on the housing; a transfer mechanism comprising a conical hopper, a conveying pipe, a dust collector, and a feeding pipe connected in sequence; and an infeed / outfeed mechanism comprising an infeed structure and an outfeed structure. This facilitates the cleaning of iron impurities adhering to magnets and enables multiple adsorption treatments of iron impurities in silicon powder, improving the iron removal effect.

[0004] However, it still has the following drawbacks in practical use: 1. In existing silicon powder processing iron removal devices, silicon powder falls in conjunction with the iron removal mechanism to remove iron. However, in this method, the silicon powder falls rapidly under the action of gravity, which reduces the iron removal time and affects the iron removal efficiency. 2. Existing silicon powder processing iron removal devices use multiple pipes to transport silicon powder during operation. However, this method still suffers from silicon powder accumulation and rapid falling, thus affecting the iron removal effect. Therefore, we provide a silicon powder processing iron removal device to solve the above-mentioned problems. Utility Model Content

[0005] The purpose of this invention is to provide a silicon powder processing iron removal device. By setting up a turbulence component, the second motor drives multiple deflectors on the chain plate to rotate counterclockwise, disturbing the falling silicon powder, thereby slowing down the falling speed of the silicon powder, increasing the iron removal time, and improving the iron removal efficiency and effect. In addition, by using a shaking component, the first motor drives the screen plate to move horizontally in a cyclical manner, so that the silicon powder can fall evenly and slowly into the first chamber, avoiding the accumulation of silicon powder and its rapid falling, which would affect the iron removal effect.

[0006] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution: This utility model is a silicon powder processing iron removal device, including a shell and a partition fixed in the middle of its inner wall. A first chamber and a second chamber are respectively arranged in front of and behind the partition. A feeding hopper is arranged at the top rear end of the shell. A shaking component is arranged inside the feeding hopper. A turbulence component is arranged on one side of the inside of the first chamber and the second chamber. The vibration assembly includes a first motor mounted on the top of the housing and a rotating plate mounted on the output shaft of the first motor; The aerodynamic assembly includes a mounting bracket mounted on the outer wall of the housing, and a second motor mounted inside the mounting bracket.

[0007] The present invention is further configured such that an iron removal mechanism is provided at the center of the partition, and guide blocks are provided at the bottom center of both the first chamber and the second chamber.

[0008] The present invention is further configured such that a cleaning brush is provided in the middle of one side wall of both the first chamber and the second chamber, and a transfer mechanism is provided on one side of the bottom of the first chamber.

[0009] The present invention is further configured such that a rod is fixedly provided at the edge of the upper surface of the rotating plate, and a linkage plate is rotatably sleeved on the outer wall of the rod.

[0010] The present invention is further configured such that the other end of the linkage plate is hinged to one side wall of the mesh plate via a hinge, and the mesh plate is slidably installed inside the feed hopper.

[0011] The present invention is further configured such that the output shaft of the second motor is connected to the rotating shaft via a coupling, and the other end of the rotating shaft passes through the bearing on the outer shell and is connected to the bearing on the outer wall of the partition.

[0012] The present invention is further configured such that an active roller is sleeved on the outer wall of the rotating shaft, and an auxiliary roller is arranged directly below the active roller, with the auxiliary roller rotatably installed between the outer shell and the partition.

[0013] The present invention is further configured such that a chain plate is sleeved on the outer wall of the active roller and the auxiliary roller, and a lever plate is evenly spaced on the outer wall of the chain plate along its direction of movement.

[0014] This utility model has the following beneficial effects: 1. This utility model, by setting up a turbulence component, uses a second motor to drive multiple deflectors on the chain plate to rotate counterclockwise, thus slowing down the falling silicon powder, increasing the iron removal time, and improving the iron removal efficiency and effect. This solves the problem that in existing silicon powder processing iron removal devices, when silicon powder falls in conjunction with the iron removal mechanism, the silicon powder falls rapidly under the action of gravity, resulting in a reduction in iron removal time and affecting the iron removal efficiency. 2. This utility model, by setting up a shaking component, uses a first motor to drive the mesh plate to move horizontally in a reciprocating motion, so that silicon powder can fall evenly and slowly into the first chamber, avoiding silicon powder accumulation and rapid falling, which would affect the iron removal effect. This solves the problem that existing silicon powder processing iron removal devices use multiple pipes to transport silicon powder, but this method still results in silicon powder accumulation and rapid falling, thus affecting the iron removal effect of silicon powder.

Detailed Implementation

[0016] 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 skilled in the art without creative effort are within the protection scope of the present utility model. Example 1

[0017] Please see Figures 1 to 5 This utility model is a silicon powder processing iron removal device, including a shell 100 and a partition 101 fixed in the middle of its inner wall. A first chamber 101a and a second chamber 101b are respectively arranged in front and behind the partition 101. A feed hopper 106 is arranged at the top rear end of the shell 100. A shaking component 200 is arranged inside the feed hopper 106. The shaking component 200 includes a first motor 201 installed on the top of the shell 100 and a rotating plate 202 installed on the output shaft of the first motor 201.

[0018] Specifically, an iron removal mechanism 102 is provided at the center of the partition 101, and a guide block 103 is provided at the center of the bottom of both the first chamber 101a and the second chamber 101b; a cleaning brush 104 is provided in the middle of one side wall of both the first chamber 101a and the second chamber 101b, and a transfer mechanism 105 is provided on one side of the bottom of the first chamber 101a; an insert rod 202a is fixed at the edge of the upper surface of the rotating plate 202, and a linkage plate 203 is rotatably sleeved on the outer wall of the insert rod 202a; the other end of the linkage plate 203 is hinged to one side wall of the mesh plate 204 through a hinge, and the mesh plate 204 is slidably installed inside the feed hopper 106.

[0019] Furthermore, the first chamber 101a is located behind the second chamber 101b and is separated by a partition 101, enabling secondary iron removal of silicon powder. The structure and principle of the iron removal mechanism 102, guide block 103, cleaning brush 104, and transfer mechanism 105 are all existing technologies and will not be described in detail here. The output shaft of the first motor 201 and the insertion rod 202a are symmetrically arranged about the center position of the rotating plate 202. One end of the linkage plate 203 is sleeved on the outer wall of the insertion rod 202a, and the other end is hinged to the mesh plate 204, which plays a transmission role. Therefore, the operation of the first motor 201 can drive the mesh plate 204 to move back and forth in a cycle.

[0020] The operation process of this embodiment is as follows: When in use, silicon powder is put into the feed hopper 106. During the silicon powder feeding process, the first motor 201 is started. The output shaft of the first motor 201 rotates, driving the rotating plate 202 to rotate. A linkage plate 203 is sleeved on the outer wall of the insert rod 202a on the upper surface of the rotating plate 202. The other end of the linkage plate 203 is hinged to the outer wall of the mesh plate 204 through a hinge. Therefore, when the rotating plate 202 rotates, it will drive the mesh plate 204 to move horizontally inside the feed hopper 106 under the action of the insert rod 202a and the linkage plate 203, so that the mesh plate 204 can move back and forth inside the feed hopper 106, thereby shaking off the silicon powder on the surface of the mesh plate 204, so that the silicon powder can fall evenly and slowly into the first chamber 101a, avoiding the accumulation of silicon powder and its rapid fall, which would affect the iron removal effect. Example 2

[0021] Please see Figure 4 and Figure 6Based on Embodiment 1, the difference from the first embodiment is that a turbulence component 300 is provided. The turbulence component 300 includes a mounting bracket 301 installed on the outer wall of the housing 100 and a second motor 302 installed inside the mounting bracket 301. This solves the problem that in the existing silicon powder processing iron removal device, when silicon powder falls in conjunction with the iron removal mechanism for iron removal, the silicon powder falls rapidly under the action of gravity, resulting in a reduction in iron removal time and affecting iron removal efficiency.

[0022] Specifically, the output shaft of the second motor 302 is connected to the rotating shaft 302a via a coupling. The other end of the rotating shaft 302a passes through the bearing on the outer shell 100 and is connected to the bearing on the outer wall of the partition 101. An active roller 303 is sleeved on the outer wall of the rotating shaft 302a. An auxiliary roller 304 is arranged directly below the active roller 303. The auxiliary roller 304 is rotatably installed between the outer shell 100 and the partition 101. A chain plate 305 is sleeved on the outer walls of the active roller 303 and the auxiliary roller 304. A lever plate 306 is evenly spaced on the outer wall of the chain plate 305 along its direction of movement.

[0023] Furthermore, the operation of the second motor 302 can drive the rotating shaft 302a to rotate, and the rotation of the rotating shaft 302a drives the active roller 303 on its outer wall to rotate, and together with the auxiliary roller 304, it can drive the chain plate 305 to rotate counterclockwise, so that multiple deflectors 306 rotate counterclockwise synchronously, disturbing the falling silicon powder and slowing down the falling speed.

[0024] The operation process of this embodiment is as follows: During the falling process of silicon powder, the iron removal mechanism 102 adsorbs the iron powder in the silicon powder, and then the iron powder is discharged from the bottom right side of the outer shell 100. The silicon powder after preliminary iron removal can be transferred to the second chamber 101b by the transfer mechanism 105. During the iron removal process of silicon powder in the first chamber 101a and the second chamber 101b, two sets of second motors 302 are started. The output shaft of the second motor 302 rotates and drives the rotating shaft 302a to rotate through the coupling. The rotation of the rotating shaft 302a can drive the active roller 303 on its outer wall to rotate. At the same time, under the action of the auxiliary roller 304, the chain plate 305 is driven to rotate counterclockwise. During this process, the silicon powder will fall between the chain plate 305 and the iron removal mechanism 102. The rotation of the chain plate 305 will drive the multiple deflectors 306 on its outer wall to rotate. The deflectors 306 can disturb the falling silicon powder, thereby slowing down the falling speed of the silicon powder, increasing the iron removal time, and improving the iron removal efficiency and effect.
