Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0039] Please see Figure 1-4 The present invention provides the following technical solution: a dust recovery device in silicon powder, including a base plate 1;

[0040] Dust collection facility 2, which includes:

[0041] 2-1 vacuum cleaner fan;

[0042] Adjustment mechanism 2-2, one end of which is fixedly connected to an arc-shaped dust suction hood 2-3;

[0043] The input end of the vacuum cleaner fan 2-1 is fixedly connected to a three-way pipe 2-4, and a flexible hose 2-5 is fixedly connected inside the three-way pipe 2-4. The other end of the flexible hose 2-5 is fixedly connected to the arc-shaped vacuum hood 2-3.

[0044] The output end of the vacuum blower 2-1 is fixedly connected to a dust exhaust hose 2-6;

[0045] A filter device 2-7 is fixedly installed on the upper surface of the base plate 1, and a dust exhaust hose 2-6 vertically penetrates the filter device 2-7;

[0046] The regulating mechanism 12-2 includes:

[0047] Fixed rail 2-2-1, servo motor 2-2-2 is fixedly mounted on the upper surface of fixed rail 2-2-1, bidirectional lead screw 2-2-3 is fixedly connected to the output end of servo motor 2-2-2, and connecting plate 2-2-4 is slidably mounted inside fixed rail 2-2-1.

[0048] In this embodiment, by cooperating with the adjustment mechanism 2-2 and the adjustment mechanism 3, the height and position of the arc-shaped dust suction hood 2-3 can be flexibly adjusted according to the location where silicon dust is generated, so as to achieve precise dust suction and effectively improve the efficiency of silicon dust recovery. The bidirectional screw 2-2-3, by rotating, helps to drive the symmetrical arc-shaped dust suction hood 2-3 to move in both directions to form a directional airflow field, covering the dust diffusion area. The hose 2-5 ensures the flexibility of movement. The design of the filter device 2-7 can effectively filter the recovered dust. The filter plate 2-7-3 facilitates the separation of air and silicon dust. The collection box 2-7-4 facilitates the centralized collection and treatment of the filtered dust, and at the same time, it is easy to remove the collection box 2-7-4 to handle silicon dust.

[0049] Specifically, the connecting plate 2-2-4 is fixedly connected to the arc-shaped dust hood 2-3, and the bidirectional lead screw 2-2-3 is threadedly connected to the connecting plate 2-2-4. When the servo motor 2-2-2 works, it drives the bidirectional lead screw 2-2-3 to rotate, thereby causing the connecting plate 2-2-4 to slide along the fixed rail 2-2-1, which in turn drives the arc-shaped dust hood 2-3 to move, thus realizing the lateral adjustment of the dust collection position.

[0050] Specifically, the vacuum cleaner fan 2-1 includes:

[0051] Motor 2-1-1, with fan blade 2-1-2 fixedly connected to its output end. When motor 2-1-1 is working, it drives fan blade 2-1-2 to rotate, generating a strong suction force that causes dust to enter the vacuum fan 2-1 through the arc-shaped dust hood 2-3, hose 2-5 and three-way pipe 2-4, and then enter the filter equipment 2-7 through the dust exhaust hose 2-6.

[0052] Specifically, filtration devices 2-7 include:

[0053] The outer shell 2-7-1 has an inclined groove 2-7-2 fixedly connected to its inner wall, and a filter plate 2-7-3 is inserted inside the inclined groove 2-7-2.

[0054] The collection box 2-7-4 is slidably installed inside the outer shell 2-7-1. The surface of the collection box 2-7-4 is equipped with a handle. The incoming dust-laden gas can be filtered through the filter plate 2-7-3 to separate the dust from the air. The separated dust slides down the inclined groove 2-7-2 into the collection box 2-7-4. The handle on the surface of the collection box 2-7-4 makes it convenient for staff to periodically pull out the collection box 2-7-4 to clean or dispose of the collected dust.

[0055] Specifically, it also includes:

[0056] Adjustment mechanism 2 3; Adjustment mechanism 2 3 includes:

[0057] Servo motor 2 3-1, the output end of servo motor 2 3-1 is fixedly connected to lead screw 3-2, and the surface of lead screw 3-2 is threadedly connected to lifting plate 3-3;

[0058] A vertical rod 3-4 is fixedly installed on the upper surface of the base plate 1. The vertical rod 3-4 passes vertically through the lifting plate 3-3. When the servo motor 3-1 is working, it drives the lead screw 3-2 to rotate, causing the lifting plate 3-3 to move up and down along the vertical rod 3-4. This allows the relevant components to be adjusted in height to adapt to different working height requirements.

[0059] Specifically, the lower surface of the base plate 1 is equipped with casters 4, which are symmetrically distributed in pairs. The casters 4 facilitate the movement and transfer of the entire device.

[0060] Specifically, there are two curved dust hoods 2-3, which are symmetrically distributed, thus increasing the dust collection range and improving dust collection efficiency.

[0061] The working principle or usage process of this utility model is as follows: First, the servo motor 2-2-2 of the adjusting mechanism 2-2 is started, causing the bidirectional lead screw 2-2-3 to rotate, thereby driving the connecting plate 2-2-4 to move, thus moving the arc-shaped dust suction hood 2-3 to the vicinity of the discharge port of the discharging mechanism. Simultaneously, if it is necessary to adjust the overall height, the servo motor 3-1 of the adjusting mechanism 3 is started, causing the lead screw 3-2 to rotate, driving the lifting plate 3-3 to move up and down, thereby adjusting the corresponding height of the device. When silicon powder is discharged, a ton bag is used to collect it. When the silicon powder is released, it will adhere to the bottom of the ton bag due to gravity, thus generating dust. When dust is generated, the dust suction fan 2-1 is started. The motor 2-1-1 drives the fan blades 2-1-2 to rotate, generating suction. Under the action of suction, the dust is dissipated. The dust enters the vacuum fan 2-1 through the arc-shaped dust hood 2-3, hose 2-5, and three-way pipe 2-4, and then enters the filter equipment 2-7 through the exhaust hose 2-6. Inside the filter equipment 2-7, the filter plate 2-7-3 filters and separates the dust, and clean air is discharged, while the dust slides into the collection box 2-7-4 along the inclined groove 2-7-2. After the collection box 2-7-4 is full, the staff can pull it out by the handle for unified processing of the recovered dust. The entire device can be easily moved to different work areas by the casters 4, realizing the effective recovery of silicon powder dust, reducing the pollution of dust to the environment and the harm to human health, and improving the recycling rate of silicon powder. The electrical equipment in this device is all externally powered and controlled by the matching control switch to operate and shut down.

[0062] Finally, it should be noted that the above descriptions are merely preferred embodiments of this utility model and are not intended to limit the utility model. The selection and detailed description of these embodiments in this specification are for the purpose of better explaining the principles and practical applications of this utility model, thereby enabling those skilled in the art to better understand and utilize it.
