Description

An automatic iron removal device for silicon micro powder Technical Field

[0001] This utility model relates to the field of iron removal technology for silicon micropowder, and in particular to an automatic iron removal device for silicon micropowder. Background Technology

[0002] Silicon micro powder is widely used as wire cutting cutting material for solar crystalline silicon wafers, semiconductor silicon wafers and quartz chips. However, during the process of pulverizing silicon carbide micro powder into micro powder, it will inevitably be mixed with iron impurities due to friction and pulverization with iron materials such as shells. Therefore, it is necessary to remove iron impurities from silicon micro powder.

[0003] Currently, during the iron removal process of silicon micropowder, the silicon micropowder is usually discharged in a pile-up manner, resulting in an excessively thick silicon micropowder conveying layer, which reduces the iron removal efficiency of silicon micropowder.

[0004] Meanwhile, when adsorbing iron fragments in silicon micropowder, the adsorbed iron fragments are usually cleaned by hand, resulting in low collection efficiency and incomplete collection of iron fragments.

[0005] Therefore, we proposed an intelligent lighting appliance energy efficiency testing device to address the problems mentioned above. Summary of the Invention

[0006] When removing iron from silicon micropowder, the push plate and sorting rod can be used to push and disperse the accumulated silicon micropowder, while the sorting rod can intercept large particles or iron blocks in the silicon micropowder, thereby improving the iron removal efficiency of silicon micropowder. At the same time, the arc scraper and rubber plate can be used to clean the iron fragments adsorbed on the surface of the electromagnetic roller, making it convenient to collect and sort the adsorbed iron fragments, thus solving the problems mentioned in the background technology.

[0007] To achieve the above objectives, the present invention adopts the following technical solution: including an operating table, a dispersing mechanism and a cleaning mechanism, wherein the dispersing mechanism includes a push plate and a sorting rod, the sorting rod being located on the right side of the push plate, the push plate and the sorting rod being used to push and sort the silicon micro powder that needs to be iron removed, so that the silicon micro powder can be dispersed and transported, thereby improving the iron removal efficiency of the silicon micro powder.

[0008] The cleaning mechanism includes an arc-shaped scraper and a rubber seat. The rubber seat is located in front of the arc-shaped scraper. The arc-shaped scraper and the rubber seat are used to clean and remove the iron adsorbed in the silicon micropowder, making it convenient to collect the adsorbed iron.

[0009] Preferably, the dispersing mechanism further includes a movable plate, on the lower surface of which a push plate and sorting rods are fixedly connected. The height of the push plate increases from left to right, and the spacing of the sorting rods increases from right to left.

[0010] Preferably, the cleaning mechanism further includes a collection box, the upper surface of which is fixedly connected to a support rod, and the top end of the support rod is fixedly connected to the lower surface of the arc scraper. The front surface of the support rod is fixedly connected to a fixing plate, and the upper surface of the fixing plate is connected to the lower surface of the rubber seat.

[0011] Preferably, a support plate is fixedly connected to the upper surface of the operating table, a material box is fixedly connected to the upper surface of the support plate, an inclined plate is fixedly connected to the inside of the material box, and a discharge pipe is fixedly connected to the lower surface of the material box.

[0012] Preferably, a first fixed frame is fixedly connected to the upper surface of the operating table, a first electric push rod is fixedly connected to the inner top wall of the first fixed frame, and the output end of the first electric push rod is connected to the moving plate. A motor is provided on the front surface of the operating table, and a conveyor belt is sleeved on the output end of the motor through a conveyor roller. The conveyor belt is located below the discharge pipe and the moving plate.

[0015] 1. In this utility model, starting the first electric push rod can drive the moving plate, the push plate, and the sorting rod to move together and fit into the surface of the conveyor belt. Since the lower surface of the moving plate is equipped with three sets of push plates, and the height of the three sets of push plates increases sequentially from left to right, they can push the accumulated silicon powder flat in sequence. The lower surface of the moving plate is equipped with three sets of sorting rods, and the spacing between each set of sorting rods is different, so that they can disperse the flattened silicon powder. At the same time, the sorting rods can intercept large particles and iron blocks in the silicon powder, thereby improving the iron removal efficiency in the silicon powder.

[0022] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0023] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention can also be implemented in other ways than those described herein, and therefore the present invention is not limited to the specific embodiments disclosed in the following specification.

[0024] Example 1, as shown in Figures 1-4, includes an operating table 1, a dispersing mechanism 10, and a cleaning mechanism 11. The dispersing mechanism 10 includes a push plate 102 and a sorting rod 103. The sorting rod 103 is located on the right side of the push plate 102. The push plate 102 and the sorting rod 103 are used to push and sort the silicon micro powder that needs to be removed from iron, so that the silicon micro powder can be dispersed and transported, thereby improving the iron removal efficiency of the silicon micro powder.

[0025] The cleaning mechanism 11 includes an arc-shaped scraper 114 and a rubber seat 113. The rubber seat 113 is located in front of the arc-shaped scraper 114. The arc-shaped scraper 114 and the rubber seat 113 are used to clean and remove the iron adsorbed in the silicon micro powder, so as to facilitate the collection of the adsorbed iron.

[0026] The overall effect achieved in Embodiment 1 is as follows: when removing iron from silicon micro powder, the push plate 102 and the sorting rod 103 can be used to push and disperse the accumulated silicon micro powder, while the sorting rod 103 can intercept large particles of impurities or iron blocks in the silicon micro powder, thereby improving the iron removal efficiency of silicon micro powder. At the same time, the arc scraper 114 and the rubber plate can be used to clean the broken iron adsorbed on the surface of the electromagnetic roller 13, making it convenient to collect and sort the adsorbed broken iron.

[0027] Example 2, as shown in Figures 1 and 3, the dispersing mechanism 10 further includes a movable plate 101. A push plate 102 and a sorting rod 103 are fixedly connected to the lower surface of the movable plate 101. The height of the push plate 102 increases from left to right, and the spacing of the sorting rods 103 increases from right to left. A first fixed frame 5 is fixedly connected to the upper surface of the operating table 1. A first electric push rod 6 is fixedly connected to the inner top wall of the first fixed frame 5, and the output end of the first electric push rod 6 is connected to the movable plate 101.

[0028] The effect achieved by the entire embodiment 2 is as follows: when silicon powder is conveyed on the surface of conveyor belt 2, the first electric push rod 6 is connected to an external power source. Activating the first electric push rod 6 can drive the moving plate 101, the push plate 102, and the sorting rod 103 to move together and fit against the surface of the conveyor belt 2. Since the lower surface of the moving plate 101 is equipped with three sets of push plates 102, and the height of the three sets of push plates 102 increases sequentially from left to right, it can push the accumulated silicon powder flat in sequence. The lower surface of the moving plate 101 is equipped with three sets of sorting rods 103, and the spacing between each set of sorting rods 103 is different, so that the flattened silicon powder can be dispersed. At the same time, the sorting rods 103 can intercept large particles and iron blocks in the silicon powder, thereby improving the iron removal efficiency in the silicon powder.

[0029] Example 3, as shown in Figures 1-2, the cleaning mechanism 11 also includes a collection box 111. A support rod 115 is fixedly connected to the upper surface of the collection box 111, and the top end of the support rod 115 is fixedly connected to the lower surface of the arc scraper 114. A fixing plate 112 is fixedly connected to the front surface of the support rod 115, and the upper surface of the fixing plate 112 is connected to the lower surface of the rubber seat 113.

[0030] The effect achieved by the entire embodiment 3 is as follows: after the iron in the silicon micro powder is completely adsorbed, the electromagnetic roller 13 can be moved to the inner top wall of the second fixed frame 4, and the collection box 111 can be pushed backward so that the arc scraper 114 and the rubber pad can pass through the interior of the second fixed frame 4 together. The electromagnetic roller 13 can be pushed downward by the second electric push rod 3 to fit the surface of the arc scraper 114 and the rubber seat 113. The collection box 111 is pushed backward so that the arc scraper 114 can scrape the iron adsorbed on the surface of the electromagnetic roller 13, so that the broken iron can fall into the interior of the collection box 111. The rubber seat 113 can wipe the broken iron remaining on the surface of the electromagnetic roller 13. The electromagnetic roller 13 can be manually rotated to clean the broken iron adsorbed on the surface of the electromagnetic roller 13, so that the debris adsorbed on the surface of the electromagnetic roller 13 can be easily collected and cleaned.

[0031] Example 4, as shown in Figures 1 and 4, a support plate 8 is fixedly connected to the upper surface of the operating table 1, a material box 7 is fixedly connected to the upper surface of the support plate 8, an inclined plate 14 is fixedly connected to the inside of the material box 7, a discharge pipe 15 is fixedly connected to the lower surface of the material box 7, a motor 9 is provided on the front surface of the operating table 1, a conveyor belt 2 is sleeved on the output end of the motor 9 through a conveyor roller, the conveyor belt 2 is located below the discharge pipe 15 and the moving plate 101, a second fixed frame 4 is fixedly connected to the upper surface of the operating table 1, and the second fixed frame 4 is located to the right of the first fixed frame 5, the interior of the second fixed frame 4 is slidably connected, a second electric push rod 3 is fixedly connected to the inner top wall of the second fixed frame 4, a mounting frame 12 is fixedly connected to the output end of the second electric push rod 3, and an electromagnetic roller 13 is movably connected to the front surface of the mounting frame 12 through a bearing.

[0032] The overall effect of embodiment 4 is as follows: silicon micro powder is poured into the material box 7. The inclined plate 14 can be used to throttle the discharge of silicon micro powder. The silicon micro powder can be discharged on the surface of the conveyor belt 2 through the discharge pipe 15. The motor 9 and the second electric push rod 3 are connected to the external power supply. The motor 9 is started so that it can drive the conveyor belt 2 to rotate using the conveyor roller. The conveyor belt 2 can rotate to convey the silicon micro powder for iron removal. When the dispersed silicon micro powder is below the second fixed frame 4 of the conveyor belt 2, the second electric push rod 3 is started to push the mounting frame 12 and the electromagnetic roller 13 to move downward, so that the electromagnetic roller 13 can be in contact with the surface of the silicon micro powder. The magnetic force on the surface of the electromagnetic roller 13 can attract the iron in the silicon micro powder. The electromagnetic roller 13 can roll due to the friction of the conveyor belt 2 to automatically remove the iron in the silicon micro powder.

[0033] The working principle of the entire equipment is as follows: silicon micro powder can be discharged onto the surface of the conveyor belt 2 through the discharge pipe 15. The motor 9 is started so that the conveyor belt 2 can be rotated by the conveyor roller, so that the conveyor belt 2 can be rotated to convey the silicon micro powder for iron removal. The first electric push rod 6 is started so that the moving plate 101, the push plate 102 and the sorting rod 103 can move together to fit against the surface of the conveyor belt 2. Since the lower surface of the moving plate 101 is equipped with three sets of push plates 102, and the height of the three sets of push plates 102 increases from left to right, it can push the accumulated silicon micro powder flat in sequence. The lower surface of the moving plate 101 is equipped with three sets of sorting rods 103, and the spacing between each set of sorting rods 103 is different, so that the flattened silicon micro powder can be spread. At the same time, the sorting rods 103 can intercept large particles and iron blocks in the silicon micro powder.

[0034] Activating the second electric push rod 3 can push the mounting frame 12 and the electromagnetic roller 13 downward, allowing the electromagnetic roller 13 to adhere to the surface of the silicon powder. The magnetic force on the surface of the electromagnetic roller 13 can attract iron in the silicon powder. Pushing the collection box 111 backward allows the arc scraper 114 and the rubber pad to pass through the interior of the second fixing frame 4. The second electric push rod 3 can push the electromagnetic roller 13 downward to adhere to the surface of the arc scraper 114 and the rubber seat 113. Continuing to push the collection box 111 backward allows the arc scraper 114 to scrape the iron attracted to the surface of the electromagnetic roller 13, allowing the iron scraps to fall into the interior of the collection box 111. The rubber seat 113 can wipe away any remaining iron scraps on the surface of the electromagnetic roller 13.

[0035] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
