[0002] Currently, in the polysilicon industry, the work platforms for carbon head sorting and scrap sorting positions are mainly flat tables. The work platform has a simple structure and its main function is to provide the space required for the operation. However, there are no specific requirements for dust removal, impurity filtration, environmental cooling, preventing products from falling, and facilitating employee operation. In the polysilicon industry, environmental cleanliness, dust removal, and impurity removal are important factors that directly affect product quality. Utility Model Content
[0003] To address the technical problem that current sorting workbenches lack dust cleaning and environmental cooling functions, this utility model provides a sorting workbench for polycrystalline silicon production. During use, the airflow from the top of the workbench is drawn into the hood through an exhaust duct, thereby removing dust from the air above the workbench and achieving environmental cleaning. The flowing airflow also reduces the temperature of the top of the workbench, achieving environmental cooling.

To simplify the disclosure, specific examples of components and arrangements are described below. These are merely examples and are not intended to limit the scope of the invention. Furthermore, reference numerals and / or letters may be repeated in different examples; such repetition is for simplification and clarity and does not in itself indicate a relationship between the various embodiments and / or arrangements discussed. In addition, examples of various specific processes and materials are provided in this invention, but those skilled in the art will recognize the application of other processes and / or the use of other materials.
[0026] The embodiments of this utility model will now be described in detail with reference to the accompanying drawings.
[0027] Example:
[0028] See Figure 1 and Figure 2 This embodiment discloses a sorting workbench for producing polycrystalline silicon, including a table 10, a cover 20, a cover plate 30, and an exhaust duct 40. The top surface of the table 10 is a plane, on which workers perform carbon head sorting and scrap sorting.
[0029] Specifically, the cover 20 has a rectangular parallelepiped structure, and the interior of the cover 20 is a hollow structure. The cover 20 is installed on the top surface of the table 10, and the length direction of the cover 20 is consistent with the length direction of the table 10.
[0030] The front and rear sides of the cover 20 are open structures, and the bottom edges of the two open sides are in contact with the top surface of the table 10. At the same time, when the workers are working, all workers are facing the open sides of the cover 20.
[0031] A cover plate 30 is provided on the open surface of the cover 20. The cover plate 30 has multiple air holes 31, and all the air holes 31 are densely distributed on the cover plate 30.
[0032] In addition, a through hole is provided at the top of the cover 20, and one end of the exhaust pipe 40 is fixedly installed in the through hole, so that the exhaust pipe 40 is connected to the interior of the cover 20. Generally speaking, a fan is installed on the pipe connected to the exhaust pipe 40.
[0033] The airflow passing through the exhaust duct 40 flows from the top surface of the table 10 into the cover 20, and then from the inside of the cover 20 into the exhaust duct 40.
[0034] In this embodiment, a cover 20 is installed on the top surface of the table 10, with a cover plate 30 having air holes 31 on the open surface of the cover 20, and an exhaust duct 40 is installed on the top surface of the cover 20. Thus, during use, workers sort carbon heads and scrap materials on both sides of the table 10 respectively, and the airflow from the top surface of the table 10 is drawn into the cover 20 through the exhaust duct 40, thereby removing dust from the air above the table 10, achieving environmental cleaning, and the flowing airflow also reduces the temperature of the top surface of the table 10, achieving environmental cooling.
[0035] In one specific embodiment:
[0036] An air valve 41 is installed on the exhaust duct 40. By installing the air valve 41, workers can adjust the airflow in the exhaust duct 40 according to their own working environment.
[0037] Preferably, two through holes are provided on the top of the cover 20, and each of the two through holes is provided with a ventilation duct 40. At the same time, each of the two ventilation ducts 40 is provided with a damper 41.
[0038] Generally, carbon head sorting and scrap sorting are carried out simultaneously on the table 10, and the workers performing carbon head sorting and scrap sorting are located at opposite ends of the table 10. Therefore, two exhaust ducts 40 and air valves 41 are designed to meet the airflow velocity difference requirements of the workers at both ends of the table 10 during their work.
[0039] In addition, a partition can be installed in the middle of the inner side of the cover 20 to form two airflow channels inside the cover 20 and avoid interference.
[0040] In another specific embodiment:
[0041] The inner side of the cover plate 30 and the open surface of the cover body 20 forms a gap between the cover plate 30 and the open surface of the cover body 20. Through this design, the open surface of the cover body 20 forms an eaves-shaped structure, thereby preventing silicon material from splashing and reducing the generation of fallen material to a certain extent, thus having the function of preventing fallen material.
[0042] In another specific embodiment:
[0043] A filter screen is provided on one end of the exhaust duct 40 that is connected to the cover 20. The filter screen can filter the dust drawn into the cover 20, so that the dust is left inside the cover 20 for easy cleaning.
[0044] Preferably, a support member (not shown in the figure) is provided at the end of the exhaust duct 40, and the support member is connected to the filter screen. Since the dust consists of fine particles, the mesh size of the filter screen is small, resulting in a large suction force on the filter screen when the exhaust duct 40 is operating. Therefore, the support member is designed to support and protect the filter screen. Generally, the support member is made of multiple metal rods.
[0045] In another specific embodiment:
[0046] The inner side of the open surface of the cover 20 is provided with multiple buckles, and the cover plate 30 is detachably connected to the buckles. By making the cover plate 30 and the cover 20 detachably connected by multiple buckles, the cover plate 30 can be easily removed after the entire workbench has been used for a certain period of time to clean the dust inside the cover 20.
[0047] In another specific embodiment:
[0048] The cover plate 30 is rotatably mounted on the cover body 20. The pivot of the cover plate 30 is parallel to the top surface of the table 10. This design simplifies the installation of the cover plate 30 after the dust inside the cover body 20 has been cleaned.
[0049] Preferably, the cover plate 30 is rotatably connected to the top surface of the cover body 20. This design can prevent dust from being stored in the dead corner formed between the cover plate 30 and the inner wall of the cover body 20.
[0050] In another specific embodiment:
[0051] The bottom surface inside the cover 20 is inclined to facilitate dust cleaning.
[0052] All the vents 31 are distributed over 95% of the area of the upper half of the cover plate 30. This design allows dust to be temporarily contained within the container formed by the cover plate 30 and the bottom of the hood 20.
[0053] The embodiments described above merely illustrate specific implementations of this utility model, and while the descriptions are detailed, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these modifications and improvements all fall within the protection scope of this utility model.
