Description

Technical Field

[0001] The utility model belongs to the technical field of raw material preparation for trimethylsilane production, and particularly relates to a raw material preparation device for trimethylsilane production. Background Art

[0002] Trimethylsilane is an important silicon source gas in the production of semiconductor devices and is often used to form Ge-Si-C layers in epitaxial chemical vapor deposition. Trimethylsilane can also decompose to form SiC under high temperature conditions, so it can also be used as a precursor material for SiC coatings. Trimethylsilane has extremely important and unique uses in the electronics industry and the defense industry.

[0003] The prior art discloses a quantitative feeding device for trimethylsilane production with application number: 202120421697.5. Through the setting of this utility model, the feeding port can be in a closed state during the testing period of the quantitative device, which is conducive to placing the raw materials into the interior of the production device without being quantified, thereby avoiding the occurrence of unexpected factors affecting trimethylsilane. This is conducive to the staff to open the channel of the feeding port in time, so that the arc-shaped material blocking plate will not affect the subsequent addition of raw materials.

[0004] In the above device, raw materials are added from the feeding port and piled on the arc-shaped material blocking plate. When in use, the arc-shaped material blocking plate is tilted to pour out the raw materials. Since the arc-shaped material blocking plate is tilted at a certain angle and the properties of the raw materials are different, after long-term use, some residual raw materials will adhere to the surface of the arc-shaped material blocking plate. When pouring, it cannot be poured out completely, and some raw materials will be wasted. Utility Model Content

[0005] The utility model aims to provide a raw material preparation device for trimethylsilane production. By adding connecting components and setting movable plates, all the raw materials on the symmetrical blocks can fall into the box body, thereby solving the problem that the arc-shaped material blocking plate cannot bring all the raw materials into the box body, and some residual raw materials will adhere to the surface, causing a certain amount of waste of raw materials.

[0006] In order to solve the above technical problems, the utility model is realized by the following technical solutions:

[0007] The utility model discloses a raw material preparation device for trimethylsilane production, comprising a box body for containing the raw materials for trimethylsilane production, wherein a top plate is slidably connected to the top of the box body, and fixed plates are fixedly connected to the outer walls on both left and right sides of the box body, and a connecting member is arranged on the top of the fixed plate; the connecting member comprises a motor fixedly connected to the top of the fixed plate, a movable rod is fixedly connected to the top of the motor, a movable disk is sleeved and fixedly connected to the outer wall of the top of the movable rod, a movable column is meshedly connected to the outer wall of the front end of the movable disk, and a limiting block is sleeved and slidably connected to the left and right ends of the movable column, and the bottom of the limiting block is fixedly connected to the top of the fixed plate.

[0008] Furthermore, a symmetrical block is fixedly connected to the right side of the movable column, and the symmetrical block passes through the top of the box and extends to the inside of the box.

[0009] Furthermore, a rotating rod passes through and is fixedly connected to the top of the box body, and a movable plate is sleeved on and fixedly connected to the outer wall of the central axis of the rotating rod.

[0010] Furthermore, a fixing groove is slidably connected to the bottom of the fixing plate, and a discharge barrel is penetrated and fixedly connected to both the front and rear ends of the box body.

[0011] Furthermore, a middle rod is passed through and fixedly connected to the bottom end of the box body, a movable bar is sleeved on and rotatably connected to the middle outer wall of the middle rod, and a support plate is sleeved on and rotatably connected to the top outer wall of the middle rod.

[0012] Furthermore, the outer walls on both sides of the support plate are fixedly connected with support blocks, and the bottom end of the middle rod is sleeved and fixedly connected with a limit plate.

[0013] Furthermore, one end of the movable bar away from the middle rod penetrates and is rotatably connected to the front rod, and the bottom end of the front rod penetrates and is rotatably connected to a sliding block.

[0014] Furthermore, one end of the sliding block away from the front end rod penetrates and is rotatably connected to an output rod, and a bottom motor is fixedly connected to the bottom of the output rod.

[0015] The utility model has the following beneficial effects:

[0016] 1. When the utility model is used, the top plate on the top of the box body is removed so that all the raw materials fall onto the symmetrical blocks. When the raw materials are mixed, the motor can be turned on, and the motor drives the movable rod to rotate, and the movable rod drives the movable disk to rotate. While the movable disk rotates, the movable disk drives the movable column to move along the limit block, and the movable column drives the symmetrical block to be pulled out from the top of the box body, so that the raw materials on the symmetrical blocks fall into the box body. At the same time, as the symmetrical blocks move, the movable plate on the rotating rod can scrape off the raw material residues adhering to the symmetrical blocks, so that all of them fall into the box body, thereby avoiding the waste of raw materials.

[0017] 2. The utility model can start the bottom motor when mixing raw materials, and the bottom motor drives the output rod to rotate. While the output rod is rotating, the output rod drives the sliding block to swing, the output rod drives the front end rod to swing, the front end rod drives the movable bar to swing, the movable bar drives the middle rod to rotate, and the middle rod drives the top box to rotate. When the box rotates, various raw materials in the box are fully mixed, which brings convenience to subsequent operations and increases the applicability of the device.
