Description

Technical Field

[0001] The utility model relates to the field of silicon powder storage, in particular to a silicon powder collecting and storing device. Background Art

[0002] After existing silicon blocks are crushed into silicon powder, they sometimes need to be temporarily stored in containers. Silicon powder is widely used, and smaller silicon powder tends to agglomerate when exposed to moisture, which in turn affects the quality of the silicon powder and reduces the quality of the finished silicon powder product. Especially for smaller silicon powder, current storage devices are unable to absorb moisture that may exist inside the silicon powder. Therefore, the risk of moisture is very high during the storage of smaller silicon powder, which affects the quality of the silicon powder after storage. When the output is large, it is difficult to preserve smaller silicon powder intact. Utility Model Content

[0003] The purpose of the utility model is to provide a silicon powder collection and storage device, which can solve the technical problem that the existing silicon powder is easily affected by moisture and deteriorates during storage. A drying tube is used to absorb moisture that may exist inside the silicon powder, and bending and deformation of the drying tube are avoided during feeding, thereby ensuring the drying effect of the drying tube during later storage, reducing the possibility of silicon powder being affected by moisture and deteriorating, and ensuring the quality of the silicon powder after storage.

[0004] In order to achieve the above purpose, the utility model is implemented through the following technical solutions:

[0005] A silicon powder collection and storage device comprises a storage box, wherein a feed port is provided on the top of the storage box, a plurality of drying tubes are distributed in a vertical array in the storage box, a plurality of through holes are provided on the side walls of the drying tubes, a guide guard plate is symmetrically connected to the storage box for rotation, a support frame for cooperating with the guide guard plate is provided on the side walls of the storage box, a feed channel is provided between the bottom end of the guide guard plate and the side wall of the storage box, and the two guide guard plates are located above the drying tubes after rotation.

[0006] Furthermore, one end of the drying pipe penetrates through the side wall of the storage box and then extends outward, and one end of the drying pipe located outside the storage box is movably connected to an end cap.

[0007] Furthermore, the end cap is threadedly connected to the end of the drying tube, and a desiccant is arranged in the drying tube.

[0008] Furthermore, the cross-section of the support frame is L-shaped, the long side of the L-shape is connected to the side wall of the storage box, and the short side of the L-shape is in contact with the bottom of the deflector protection plate.

[0009] Furthermore, a telescopic rod is rotatably connected to the lower part of the support frame, and a movable end of the telescopic rod is rotatably connected to the deflector protection plate.

[0010] Furthermore, when the deflector protection plate contacts the support frame, the tops of the two deflector protection plates contact each other.

[0011] Compared with the prior art, the beneficial effects of the present invention are:

[0012] 1. The utility model arranges a plurality of drying tubes in a vertical array in the storage box, and a plurality of through holes are arranged on the side wall of the drying tube. Meanwhile, a guide protection plate is arranged above the drying tube, and a feeding channel is arranged between the bottom end of the guide protection plate and the side wall of the storage box. Such a structure uses the drying tube to absorb moisture inside the storage box, so that silicon powder with a smaller size is not easily affected by moisture during storage. Meanwhile, the guide protection plate above is used to protect the drying tube, so that when the silicon powder enters the storage box, it enters from the side feeding channel along the inclined guide protection plate, so as to avoid the drying tube from being crushed during the silicon powder feeding process, thereby ensuring the integrity of the drying tube and ensuring a sufficient drying effect;

[0021] The present invention is further described below in conjunction with specific embodiments. It should be understood that these embodiments are only used to illustrate the present invention and are not used to limit the scope of the present invention. In addition, it should be understood that after reading the content taught by the present invention, those skilled in the art can make various changes or modifications to the present invention, and these equivalent forms also fall within the scope defined by the present application.

[0022] Reference Figure 1 and Figure 2The utility model is a silicon powder collection and storage device, the main structure of which includes a storage box 1. In order to improve the sealing performance, the storage box 1 is generally only open at the top, and the other positions are sealed. A feed port 2 is provided on the top of the storage box 1, and silicon powder enters the storage box 1 from the feed port 2. A plurality of drying pipes 3 fixed by welding or bolts are distributed along a vertical array in the storage box 1. The drying pipes 3 are distributed in a vertical array, so that moisture at various positions in the storage box 1 can be absorbed to improve the drying effect inside the storage box 1. A plurality of through holes 4 are provided on the side walls of the drying pipes 3. The desiccant can be stored inside or connected to an external dehumidification system, so that the desiccant absorbs moisture inside the storage box 1 through the through hole 4, or extracts moisture from the storage box 1 through the through hole 4, thereby achieving drying treatment inside the storage box 1. The storage box 1 is symmetrically connected with a guide guard plate 5 through a pin shaft or a hinge. Specifically, the bottom end of the guide guard plate 5 is connected to the side wall of the storage box 1 through a pin shaft or a hinge. The side wall of the storage box 1 is provided with a support frame 6 used in conjunction with the guide guard plate 5. Specifically, the support frame 6 is fixed to the side wall of the storage box 1 by welding or bolts. After the guide guard plate 5 rotates, it contacts with the support frame 6, and the support frame 6 is used to support the guide guard plate 5 to ensure the stability of the structure after rotation. A feed channel 7 is provided between the bottom end of the guide guard plate 5 and the side wall of the storage box 1. After the guide guard plate 5 rotates to an inclined state, it is supported by the support frame 6. The silicon powder entering from the feed port 2 first falls on the inclined guide guard plate 5, slides along the inclined guide guard plate 5 to the feed channel 7, and falls from the feed channel 7 to the bottom of the storage box 1. The two guide guard plates 5 are located above the drying pipe 3 after rotation. Such a structure makes After being rotated, the guide guard plate 5 is rotated to the top of the drying tube 3, and the inclined structure is used to smoothly guide the silicon powder, so that the silicon powder falls into the storage box 1 from the feeding channels 7 on both sides, so as to avoid the drying tube 3 being crushed during the silicon powder feeding process, thereby ensuring the integrity of the drying tube 3 and the subsequent drying effect of the silicon powder inside the storage box 1. When the silicon powder needs to be taken from the feed port 2 later, the guide guard plate 5 is rotated in the opposite direction so that it is rotated to the vertical direction or fits on the side wall of the storage box 1, so that the feed port 2 is no longer blocked, thereby ensuring the convenience of taking the silicon powder, and making the storage and retrieval of the silicon powder more convenient and flexible.

[0023] Preferably, one end of the drying tube 3 passes through the side wall of the storage box 1 and extends outward, and the end of the drying tube 3 located outside the storage box 1 is movably connected with an end cap 8. By opening the end cap 8, the desiccant inside the drying tube 3 can be filled or replaced from the outside, and it can also be connected to an external dehumidification system through a pipeline to achieve rapid drying of the inside of the storage box 1, thereby greatly improving the convenience of using the drying tube 3.

[0024] Preferably, refer to Figure 4 The end cap 8 is threadedly connected to the end of the drying tube 3, so that the end cap 8 can be quickly disassembled and assembled by rotation. A desiccant is arranged in the drying tube 3, generally calcium oxide or silicon dioxide commonly used in the market can be used, so that moisture can smoothly contact with the desiccant inside the drying tube 3 after passing through the through hole 4, thereby ensuring the dry state of the silicon powder in the storage box 1 and preventing the silicon powder from getting damp.

[0025] Preferably, refer to Figure 5 The cross-section of the support frame 6 is L-shaped, and the long side of the L-shape is connected to the side wall of the storage box 1 by welding or bolts, and the short side of the L-shape is in contact with the bottom of the deflector protection plate 5. Such a structure utilizes the connection between the long side and the storage box 1 to ensure the overall contact area between the support frame 6 and the storage box 1, thereby improving the stability of the support frame 6 structure, so that the short side can provide more stable and effective support for the rotated deflector protection plate 5.

[0026] Preferably, a telescopic rod 9 is rotatably connected to the bottom of the support frame 6 via a pin or a hinge. Specifically, a cylinder or an electric cylinder structure can be adopted. The movable end of the telescopic rod 9 is rotatably connected to the guide guard plate 5. Specifically, the movable end of the telescopic rod 9 is rotatably connected to the side of the guide guard plate 5 via a pin or a hinge. Such a structure can drive the guide guard plate 5 to rotate when the telescopic rod 9 telescopes, thereby realizing automatic switching of the state of the guide guard plate 5, thereby improving the convenience of its cooperation when feeding or taking silicon powder.

[0027] Preferably, refer to Figure 3 When the guide guard plates 5 are in contact with the support frame 6, the tops of the two guide guard plates 5 are in contact. This structure allows the two guide guard plates 5 to form a relatively closed inverted V-shaped structure when they are rotated to the top of the drying tube 3, so that the silicon powder can completely slide down from both sides of the guide guard plates 5 when feeding, making the protection of the drying tube 3 below more rigorous and effective.

[0028] Working principle: The utility model is provided with a plurality of drying tubes 3 in a vertical array in a storage box 1, a plurality of through holes 4 are provided on the side wall of the drying tubes 3, and a guide protection plate 5 is provided above the drying tubes 3, and a feeding channel 7 is provided between the bottom end of the guide protection plate 5 and the side wall of the storage box 1. Such a structure utilizes the drying tubes 3 to absorb moisture inside the storage box 1, so that silicon powder of smaller size is not easily affected by moisture during storage, and utilizes the guide protection plate 5 above to protect the drying tubes 3, so that when the silicon powder enters the storage box 1, it enters from the side feeding channel 7 along the inclined guide protection plate 5, so as to avoid the drying tubes 3 being crushed during the silicon powder feeding process, thereby ensuring the integrity of the drying tubes 3 and protecting the silicon powder. To ensure a sufficient drying effect; the guide protection plate 5 is rotatably connected in the storage box 1, and at the same time, a support frame 6 used in conjunction with the guide protection plate 5 is provided on the side wall of the storage box 1. Such a structure rotates the guide protection plates 5 on both sides during feeding so that both are located above the drying tube 3, and uses the support frame 6 to support the guide protection plate 5, thereby achieving smooth guidance of silicon powder feeding and effective protection of the drying tube 3. When the silicon powder is taken out, the guide protection plates 5 on both sides can be rotated in the opposite direction to be rotated vertically or attached to the side wall of the storage box 1, so that the feed port 2 is no longer blocked, making it more convenient to take the silicon powder from the feed port 2, further improving the convenience of storing and accessing the silicon powder.
