Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of silicon powder processing, and particularly relates to a bagging device for silicon powder processing. Background Art
[0002] Silicon powder is a powdery silicon material prepared by taking silica as a raw material and through methods such as cleaning, impurity removal, and grinding. After being processed into a finished product, the silicon powder needs to be packaged. The process mainly involves sub-packaging the silicon powder into each bag. When the existing silicon powder is bagged, during the process of the raw material falling into the bag, some fine silicon powder particles will float, resulting in the floating silicon powder floating out from the gap between the pipeline and the opening of the bag during the bagging process, causing dust to easily float around the equipment. And silicon powder belongs to explosive dust. If there is too much floating silicon powder in the workshop, it is easy to cause potential safety hazards of inflammable and explosive. To solve this problem, the existing solution is to tightly wrap the opening of the bag around the outside of the pipeline to solve the problem of silicon powder floating.
[0003] However, this method of wrapping the bag around the outside of the pipeline, such as using ropes or zip ties, etc., to put the opening of the bag on the bottom end of the pipeline and fix it. In this way, every time the bag is replaced, it is necessary to first release the fixation, remove the original bag, then replace the new bag and re-fix it. The steps of releasing the fixation and re-fixing extend the time required to replace the new bag, thereby reducing the bagging efficiency of the silicon powder. Moreover, this method can only reduce the problem of silicon powder floating. There will still be floating silicon powder in the upper part of the bag and the lower part of the pipeline. When the bag and the pipeline are separated after the bagging is completed, the silicon powder in these two areas will still float around the equipment, resulting in safety hazards still existing in the workshop. Content of the Utility Model
[0004] To solve the problems existing in the prior art, the utility model provides a bagging device for silicon powder processing. Compared with the existing bagging method, the steps of releasing the fixation and re-fixing occur during the silicon powder feeding and bagging process, and will not delay the time required to replace the new bag, thereby improving the bagging efficiency of the silicon powder. During the silicon powder bagging process, the silicon powder will not float around the equipment, avoiding potential safety hazards in the workshop.
[0005] To achieve the above purpose, the utility model provides the following technical solutions:
[0006] A silicon powder processing and bagging device, comprising a bottom plate. On the left side of the top of the bottom plate, a mounting plate is fixedly connected. On the right side of the mounting plate, a hopper is fixedly connected. The bottom of the hopper is communicated with a discharge pipe. On the top of the bottom plate, a box body is fixedly connected. On the top of the bottom plate, a blower is fixedly connected. The air inlet end of the blower extends into the box body. Inside the box body, a filter screen is fixedly connected on the right side of the air inlet end of the blower. On the top of the box body, a sealing bearing is fixedly connected. Inside the sealing bearing, a rotating pipe is fixedly connected. The bottom end of the rotating pipe extends into the box body and is located on the right side of the filter screen. On the top of the bottom plate, a motor is fixedly connected. The output shaft of the motor is fixedly sleeved with a first gear. On the rotating pipe, a second gear meshing with the first gear is fixedly sleeved. The top end of the rotating pipe is fixedly connected with a turntable. On the turntable, two symmetrical feeding ports are opened. The bottom end of the discharge pipe is attached to the upper surface of the turntable and corresponds to one of the feeding ports. At the bottom of the turntable, two placing boxes are fixedly connected respectively below the feeding ports. The top of the placing box is provided with an opening. Inside the turntable, an air duct is opened. The rotating pipe is communicated with the two feeding ports through the air duct.
[0007] Further, a plurality of hooks are fixedly connected to the inner wall of the placing box, and the plurality of hooks are distributed on the left side, right side and rear side of the placing box.
[0008] Further, box doors are hinged on the front sides of the placing box and the box body respectively.
[0009] Further, on the right side of the top of the bottom plate, a support rod is fixedly connected. The top end of the support rod is fixedly connected with a baffle plate. The baffle plate is located above the other feeding port and is attached to the upper surface of the turntable.
[0010] Compared with the prior art, the beneficial effects of the present utility model are as follows:
[0011] 1. Through the two placing boxes and their corresponding feeding ports, and in cooperation with the way that the motor drives the turntable to rotate, when the discharge pipe fills the bag in one placing box with silicon powder, a new bag can be directly loaded into the other placing box. In this way, after the bagging is completed, there is no need to release the fixation of the original bag. The new bag and the original bag can be directly exchanged in position by rotation, and then the new bag can be directly fed. When feeding, the fixation of the original bag is released and a new bag is replaced. Compared with the existing bagging method, the steps of releasing the fixation and re-fixing both occur during the silicon powder feeding and bagging process, without delaying the time for replacing the new bag, thus improving the silicon powder bagging efficiency.
[0012] 2. By the cooperation of the turntable and the discharge pipe, the silicon powder in the discharge pipe can only be discharged and fed when the discharge pipe corresponds to the feed inlet. In this way, during the bagging process, when the discharge pipe just corresponds to the feed inlet, the silicon powder can only be fed and will not float into the workshop. After the bagging is completed, the discharge pipe is blocked by the turntable, so that the silicon powder cannot be fed, and the silicon powder in the discharge pipe will not float into the workshop either. By means of the air duct, the rotating pipe, the box body and the filter screen, and cooperating with the fan to generate negative pressure, the floating silicon powder in this area is collected into the box body, and thus the dust floating at the bagging position is also treated. In this way, during the silicon powder bagging process, the silicon powder will not float around the equipment, avoiding potential safety hazards in the workshop.
[0013] 3. Through the separately arranged hooks, when the bag is hung, it is convenient to open the opening of the bag. Through the box door, it is convenient to take and place the bag and the collected silicon powder. Through the support plate and the baffle, one of the feed inlets is blocked, avoiding the phenomenon that the floating silicon powder at one feed inlet drifts out through the air duct from the other feed inlet.

Embodiment
[0019] See the appendix Figure 1-2 As shown, a silicon powder processing and bagging device includes a bottom plate 1. On the left side of the top of the bottom plate 1, a mounting plate 2 is fixedly connected. On the right side of the mounting plate 2, a hopper 3 is fixedly connected. The bottom of the hopper 3 is communicated with a discharge pipe 4. On the top of the bottom plate 1, a box body 5 is fixedly connected. On the top of the bottom plate 1, a blower 6 is fixedly connected. The air inlet end of the blower 6 extends into the box body 5. Inside the box body 5, a filter screen 7 is fixedly connected on the right side of the air inlet end of the blower 6. On the top of the box body 5, a sealed bearing 8 is fixedly connected. Inside the sealed bearing 8, a rotating pipe 9 is fixedly connected. The bottom end of the rotating pipe 9 extends into the box body 5 and is located on the right side of the filter screen 7. On the top of the bottom plate 1, a motor 10 is fixedly connected. The output shaft of the motor 10 is fixedly sleeved with a first gear 11. On the rotating pipe 9, a second gear 12 meshing with the first gear 11 is fixedly sleeved. The top end of the rotating pipe 9 is fixedly connected with a turntable 13. On the turntable 13, two symmetrical feed inlets 14 are provided. The bottom end of the discharge pipe 4 is attached to the upper surface of the turntable 13 and corresponds to one of the feed inlets 14. At the bottom of the turntable 13, two placing boxes 15 are fixedly connected, which are respectively located below the feed inlets 14. The top of the placing box 15 is provided with an opening. Inside the turntable 13, an air duct 16 is provided. The rotating pipe 9 is communicated with the two feed inlets 14 through the air duct 16.
[0020] On the inner wall of the placing box 15, a plurality of hooks 17 are fixedly connected. The plurality of hooks 17 are distributed on the left side, right side and rear side of the placing box 15.
[0021] On the front sides of the placing box 15 and the box body 5, box doors are respectively hinged.
[0022] On the right side of the top of the bottom plate 1, a support rod 18 is fixedly connected. The top end of the support rod 18 is fixedly connected with a baffle 19. The baffle 19 is located above the other feed inlet 14 and is attached to the upper surface of the turntable 13.
[0023] Working principle: In this utility model, first, fix the bag in a placement box 15. The process is as follows: Open the door of the placement box 15, hang the bag with the opening facing upwards on each hook 17. The separately arranged hooks 17 keep the opening of the bag open, then close the box door, and then rotate the placement box 15 to the left. The process is as follows: Start the motor 10 to drive the first gear 11 to rotate. The first gear 11 drives the second gear 12 to rotate. The second gear 12 drives the rotating pipe 9 to rotate. The sealing bearing 8 maintains the sealing effect between the rotating pipe 9 and the top of the box body 5. The rotating pipe 9 drives the turntable 13 to rotate. The turntable 13 drives the placement box 15 to rotate. When the feed inlet 14 above the placement box 15 does not correspond to the discharge pipe 4, the bottom end of the discharge pipe 4 is blocked by the turntable 13, preventing the silicon powder in the hopper 3 from overflowing from the discharge pipe 4. Furthermore, the silicon powder in the discharge pipe 4 will not float out. When the discharge pipe 4 corresponds to the feed inlet 14, start feeding and bagging. The silicon powder in the hopper 3 falls from the discharge pipe 4, passes through the feed inlet 14, and enters the bag in the placement box 15. During this feeding process, install a new bag in the right placement box 15. The installation process is the same as the above method. After the left bag is filled, the floating silicon powder generated during bagging is divided into two parts. One part is inside and below the valve of the discharge pipe 4, and the other part is at the feed inlet 14 and inside the placement box 15. Start the fan 6 and rotate the turntable 13 by 180 degrees to exchange the positions of the two placement boxes 15. The rotation process of the turntable 13 is the same as the above method. During this process, the bottom end of the discharge pipe 4 fits with the turntable 13, and the floating silicon powder inside cannot overflow. At the same time, the fan 6 generates negative pressure, and the silicon powder in the other part enters the air duct 16 along with the airflow, passes through the rotating pipe 9, and falls into the box body 5. After being filtered by the filter screen 7, it gathers in the box body 5. After the rotation is completed, the silicon powder falls again and is filled into the new bag. During this process, remove the bag filled with silicon powder from the hook 17 and hang a new bag. By repeating this process, the bagging work can be carried out.
