Description

Technical Field

[0001] This utility model relates to the field of rapid dust removal, and in particular to a rapid dust removal device for particulate silicon. Background Technology

[0002] A certain amount of silicon powder is generated during the production of granular silicon. Moreover, granular silicon has a large specific surface area, making it very easy to adsorb a certain amount of silicon powder.

[0003] An investigation revealed that existing vacuum adsorption dust removal equipment and electrostatic dust removal equipment are too expensive. Furthermore, since the granular silicon needs to be shaken after static electricity is removed to remove dust from the surface of the granular silicon, existing dust removal devices cannot effectively shake the granular silicon, which easily leads to dust residue, resulting in a decrease in efficiency and quality.

[0004] Therefore, in response to the problems mentioned above, this utility model proposes a rapid dust removal device for particulate silicon to solve the aforementioned problems. Summary of the Invention

[0005] This utility model aims to at least partially solve one of the technical problems in the above-mentioned technologies.

[0006] To achieve the above objectives, the first aspect of this utility model proposes a rapid dust removal device for particulate silicon, comprising: a plurality of mounting grooves on the side wall of a main frame, and a feed inlet on the main frame; a lead screw assembly disposed on one side of the mounting grooves; an ion fan, a screening assembly, and a fan disposed inside the main frame; the screening assembly comprising: a plurality of screens, one end of which is hinged to the main frame, and the other end of which is located in the mounting groove; a plurality of through holes on the screens, and a fixing block disposed on one side of each screen, the fixing block being located in the mounting groove; one end of the fixing block being connected to the screens, and the other end passing through the mounting groove and located in the lead screw assembly; support plates disposed on the main frame on one side of the mounting groove; a plurality of springs, both ends of which are connected to the fixing block and the support plates respectively; the ion fan disposed on the main frame between the screens and the feed inlet; a plurality of fans disposed on the main frame between two screens; a reciprocating lead screw disposed on one side of the mounting groove, and a slider disposed on the reciprocating lead screw; the slider, when moving on the reciprocating lead screw, will collide with the fixing block.

[0007] In addition, the particulate silicon rapid dust removal device proposed above according to this utility model may also have the following additional technical features:

[0008] Furthermore, the lead screw assembly also includes a reciprocating lead screw shaft connected and disposed within the mounting bracket, and the output end of the drive motor connected to the reciprocating lead screw.

[0009] Furthermore, a storage box is provided at the bottom of the main frame, and a handle is provided on the storage box.

[0010] Furthermore, the bottom of the mounting bracket is provided with an openable cover plate, and the cover plate is provided with a handle.

[0011] Furthermore, a baffle is provided on the sieve disc, and the baffle surrounds the sieve disc.

[0012] According to the present invention, the rapid dust removal device for granular silicon can drive the screen discs to vibrate by a slider that makes reciprocating linear motion on a reciprocating screw, and a fan is set between the two screen discs to blow the dust off the screen discs. The present invention can effectively vibrate the granular silicon, thereby effectively removing dust from the surface of the granular silicon, thus improving the efficiency of dust removal from granular silicon, and reducing the possibility of dust re-adsorbing granular silicon by the fan.

[0019] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model.

[0020] The particle silicon rapid dust removal device of this utility model embodiment will be described below with reference to the accompanying drawings.

[0021] like Figures 1 to 2 As shown, the particulate silicon rapid dust removal device of this utility model embodiment may include...

[0022] Specifically, multiple mounting slots 11 are provided on the side wall of the main frame 1, and the feed port 12 is provided on the main frame 1.

[0023] It should be noted that a storage box 6 is provided at the bottom of the main frame 1, and a handle is provided on the storage box 6.

[0024] Understandably, the storage box 6 can collect the dust-removed silicon particles, and the storage box 6 can be pulled out from the main frame 1 by pulling the handle.

[0025] The lead screw assembly 2 is located on one side of the mounting slot 11;

[0026] The ion fan 3, the screening component 4 and the fan 5 are respectively installed inside the main frame 1;

[0027] Specifically, the screening component 4 includes: multiple screening trays 41 with one end hinged to the main frame 1 and the other end located in the mounting groove 11.

[0028] It should be noted that a baffle 412 is provided on the sieve plate 41, the baffle 412 surrounds the sieve plate 41, the sieve plate 41 has multiple through holes, and a fixing block 411 is provided on one side, the fixing block 411 is located in the mounting groove 11.

[0029] Understandably, the baffle 412 provided on the sieve tray 41 can prevent the silicon particles from falling off the sieve tray 41.

[0030] It should be further noted that one end of the fixing block 411 is connected to the screen plate 41, and the other end passes through the mounting groove 11 and is located inside the lead screw assembly 2.

[0031] It is understandable that when the lead screw assembly 2 moves, it will collide with the fixed block 411, thereby causing the screen plate 41 to shake.

[0032] Specifically, a support plate 42 is provided on the main frame 1 on one side of the mounting slot 11, and multiple springs 43 are connected at both ends to the fixing block 411 and the support plate 42 respectively.

[0033] It is understandable that when the screen plate 41 vibrates, it will be reset by the cooperation of the springs 43 and the support plate 42 on both sides. The springs 43 on both sides can also provide support for the screen plate 41, so that the fixing block 411 will not stick to the mounting groove 11, thus giving the fixing block 411 enough space to vibrate in the mounting groove 11.

[0034] Specifically, the ion fan 3 is installed on the main frame 1 between the screen plate 41 and the feed inlet 12, and multiple fans 5 are respectively installed on the main frame 1 between the two screen plates 41.

[0035] Understandably, the ion fan 3 can eliminate static electricity from the granular silicon entering through the feed inlet 12 and shake off the dust through the screen plate 41 located below it. The fan 5 located between the two screen plates 41 can blow the dust shaken off the granular silicon from the mounting groove 11 into the mounting frame 23.

[0036] Specifically, the reciprocating screw 21 is located on one side of the mounting groove 11, and a slider 22 is provided on the reciprocating screw 21. When the slider 22 moves on the reciprocating screw 21, it will hit the fixed block 411.

[0037] It should be noted that the lead screw assembly 2 also includes a reciprocating lead screw 21 shaft connected and disposed in the mounting bracket 23, and the output end of the drive motor 24 is connected to the reciprocating lead screw 21.

[0038] It is understandable that the drive motor 24 will drive the reciprocating screw 21 to rotate, thereby causing the slider 22 set on the reciprocating screw 21 to move linearly back and forth along the reciprocating screw 21. During the movement, the slider 22 will hit the fixed block 411 extending from the mounting groove 11, thereby causing the screen plate 41 connected to the fixed block 411 to shake.

[0039] To better explain this utility model, the specific operation process of this utility model is as follows: the operator starts the drive motor 24, at which time the drive motor 24 will drive the reciprocating screw 21 to rotate, thereby causing the slider 22 set on the reciprocating screw 21 to move linearly back and forth along the reciprocating screw 21. During the movement, the slider 22 will hit the fixed block 411 extending from the mounting groove 11, thereby causing the screen plate 41 connected to the fixed block 411 to shake.

[0040] At this time, the staff starts the ion blower 3 and fan 5 and pours the granular silicon into the feed port 12. The granular silicon falling into the main frame 1 will pass through the ion blower 3 and be eliminated by the air blown out by the ion blower 3, and fall onto the shaking screen plate 41. As the screen plate 41 shakes, the dust will fall off the surface of the granular silicon and be blown into the bottom of the mounting frame 23 by the fan 5 set below it through the mounting groove 11. After the shaking of multiple screen plates 41, the granular silicon that has finally completed the dust removal will fall into the storage box 6.

[0041] Because the bottom of the mounting bracket 23 is provided with an openable cover plate 231, and the cover plate 231 is provided with a handle, the dust at the bottom of the mounting bracket 23 can be cleaned by opening the cover plate 231.

[0042] In summary, the rapid dust removal device for particulate silicon according to the embodiments of this utility model can improve the efficiency of particulate silicon dust removal, reduce the cost of using particulate silicon dust removal, and collect dust to prevent it from drifting into the air and polluting the environment.
