Detailed Implementation

[0018] The embodiments of the present invention are described in detail below. Examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, but should not be construed as limiting the present invention.

[0019] Example 1:

[0020] like Figure 1 and Figure 2 As shown, where Figure 1 This is a schematic diagram of the overall structure of the nano-silicon powder heating device. Figure 2 This is a schematic diagram of the stirring rod 107. This utility model provides a nano-silicon powder heating device, including a base 101, a heating chamber 102, an electric heating tube 103, a temperature sensor 104, a discharge valve 105, and a stirring assembly. The stirring assembly includes a rotating shaft 106, a stirring rod 107, a first toothed synchronous pulley 108, a positioning frame 109, a drive motor 110, a second toothed synchronous pulley 111, a toothed synchronous belt 112, a limiting component, and an abutting component. The limiting component includes a limiting plate 113 and a fixing bolt 114, and the abutting component includes a fixing block 115 and an abutting screw 116. The aforementioned solution solves the problem in existing nano-silicon powder heating devices where the heated materials are difficult to move during heating, hindering their heating. It is understood that the aforementioned solution can stir the nano-silicon powder, increasing the mobility between materials and allowing the heated materials to move, thus facilitating heating.

[0021] In this embodiment, the heating chamber 102 is welded to the base 101. Multiple electric heating tubes 103 and a temperature sensor 104 are provided on the top cover of the heating chamber 102. A discharge valve 105 is installed at the bottom. A heat-insulating coating is provided on the inner wall surface of the heating chamber 102. The base 101 is used for device fixation. A removable cover is provided on the top of the heating chamber 102. The electric heating tubes 103 are used for heating. The temperature sensor 104 is used for internal temperature monitoring. The discharge valve 105 is used for material discharge. The heat-insulating coating can prevent heat from the inside of the heating chamber 102 from being conducted to the outside, thus preventing burns to workers.

[0022] The rotating shaft 106 is mounted on the top cover plate of the heating chamber 102 via a rotating bearing. The stirring rod 107 is welded below the rotating shaft 106. The first toothed synchronous pulley 108 is fixed to the top of the rotating shaft 106. The positioning frame 109 is mounted on the top cover plate of the heating chamber 102 and is close to the first toothed synchronous pulley 108. The drive motor 110 is fixed on the positioning frame 109. The second toothed synchronous pulley 111 is fixed on the output shaft of the drive motor 110. The toothed synchronous belt 112 meshes with the first toothed synchronous pulley 108 and the second toothed synchronous pulley 111 respectively and is located on the side of the first toothed synchronous pulley 108 close to the second toothed synchronous pulley 111. The limiting member is disposed on the top of the rotating shaft 106, and the abutting member is disposed on the side of the positioning frame 109 close to the drive motor 110. The top stepped shaft of the rotating shaft 106 is mounted on the top cover plate of the heating chamber 102 via a rotary bearing. The cover plate has a bearing mounting cavity and a bearing limiting end cap for engagement. Multiple stirring rods 107 are provided at the bottom of the rotating shaft 106, with the bottommost stirring rod 107 and the uppermost stirring rod 107 arranged in a stepped configuration. The first toothed synchronous pulley 108 is mounted on the top of the rotating shaft 106 via a flat key and is limited by the limiting component. The positioning frame 109 is fixed by positioning pins and bolts. The positioning frame 109 has symmetrically arranged adjusting grooves to facilitate the driving... The drive motor 110 is fixed by a screw. The drive motor 110 is mounted on the positioning frame 109 by a T-shaped fixing screw and a nut, and its position is maintained by the abutment member. The second toothed synchronous pulley 111 is mounted on the output shaft of the drive motor 110 by a flat key. A circular locking piece and a bolt are provided at the bottom of the second toothed synchronous pulley 111 to tighten it on the output shaft of the drive motor 110 to prevent it from disengaging during transmission. The toothed synchronous belt 112 is used for transmission engagement, and its tension is adjusted by moving the position of the drive motor 110.

[0023] Secondly, the limiting plate 113 is disposed on the top of the first toothed synchronous pulley 108; the fixing bolt 114 is threadedly connected to the rotating shaft 106 and slidably connected to the limiting plate 113, and passes through the limiting plate 113. The limiting plate 113 is a circular plate with a through hole in the center to facilitate the passage of the fixing bolt 114. The fixing bolt 114 is T-shaped, and its front external thread end is screwed onto the rotating shaft 106, thereby limiting the installation of the first toothed synchronous pulley 108.

[0024] Then, the fixing block 115 is fixed on the positioning frame 109 and located on the side of the positioning frame 109 close to the drive motor 110; the abutting screw 116 is threadedly connected to the fixing block 115 and passes through the fixing block 115, and its front end can abut against the front end cover of the drive motor 110. There are two abutting screws 116. The fixing block 115 is fixed to the positioning frame 109 by positioning pins and bolts, with the positioning pins and bolts arranged from bottom to top. The fixing block 115 has two symmetrical threaded holes to facilitate the installation of the abutting screw 116. The front side of the abutting screw 116 is a stepped shaft, and the rear side has an external hexagonal end for abutment. When the nut on the fixing screw of the drive motor 110 is loosened but not completely removed, the abutting screw 116 is rotated away from the drive motor 110, and the drive motor 110 can be pushed directly towards the side closer to the rotating shaft 106, so that the toothed synchronous belt 112 can be quickly fitted. After fitting, the abutting screw 116 is rotated to push the drive motor 110 away from the rotating shaft 106. When the toothed synchronous belt 112 is tensioned, the rotation of the abutting screw 116 is stopped, and the nut on the fixing screw of the drive motor 110 is tightened.

[0025] Finally, the controller 117 is electrically connected to the electric heating element 103, the temperature sensor 104, and the drive motor 110 via power lines. The controller 117 internally houses electrical control components such as a PLC, and has corresponding control buttons and a display screen on its front side for easy equipment operation, control, and data display.

[0026] When using this invention to solve the problem that the position of the heated materials inside existing nano-silicon powder heating devices is not easy to move during heating, which is not conducive to the heating of the materials, the device is first fixed by the base 101. Then, the discharge valve 105 is closed and the raw material is added through the movable door provided on the top cover plate of the heating chamber 102. Furthermore, several electric heating tubes 103 are controlled to work to heat the inside of the heating chamber 102, thereby heating the nano-silicon powder. At the same time, the drive motor 110 is controlled to drive the second toothed synchronous wheel 111 to rotate. This drives the toothed synchronous belt 112 to move, and drives the first toothed synchronous pulley 108 to rotate, thereby rotating the shaft 106. Finally, the stirring rod 107 can rotate, which can stir the nano-silicon powder, increase the mobility between materials, and allow the heated objects to move, which is beneficial for the materials to be heated. When the stirring rod 107 rotates, it will not collide with the working part of the electric heating tube 103 and the temperature sensor 104, thus solving the problem that the heated objects in the existing nano-silicon powder heating device are not easy to move during heating, which is not conducive to the heating of the heated objects.

[0027] Example 2:

[0028] like Figure 3 As shown, where Figure 3 This is a schematic diagram of the overall structure of the nano-silicon powder heating device. Based on the first embodiment, this utility model provides a nano-silicon powder heating device, which also includes a protective component, including an isolation cover 201 and a ventilation plate 202.

[0029] The isolation cover 201 is fixed to the cover plate on the top of the heating chamber 102; the ventilation plate 202 is fixed to the top of the isolation cover 201. The interior of the isolation cover 201 is a rectangular cavity for the working components to pass through, and mounting ears are provided on both sides for fixing with bolts. The ventilation plate 202 is fixed with bolts.

[0030] In this embodiment, the isolation cover 201 can isolate the toothed synchronous belt 112 during rotation to ensure safety, and the ventilation plate 202 can facilitate air circulation between the inside and outside, which is beneficial for the heat dissipation of the drive motor 110 and provides safety protection.
