Description

Technical Field

[0001] This utility model relates to the field of sealing mechanisms for color sorters, and more particularly to a sealing mechanism for a multi-layer color sorter. Background Technology

[0002] Color sorters use optical glass to isolate and seal the identification device from the material to be sorted, preventing various impurities, water, and dust from entering the identification device, thereby ensuring the working performance of the color sorter.

[0003] To ensure that the identification device in the color sorter is as close as possible to the material to be sorted, the distance between the identification device and the optical glass and the material to be sorted is usually small. When the material to be sorted passes through the identification device, it may come into direct contact with the optical glass. Over time, scratches will appear on the surface of the optical glass, and some of the material to be sorted may even adhere to the surface of the optical glass, making it impossible for the identification device to identify and judge the material. In some cases, the material may even damage and corrode the glass during long-term adhesion, causing the seal of the identification device to fail. Utility Model Content

[0004] To address the aforementioned problems, the present invention aims to provide a sealing mechanism for a multi-layer color sorter, thereby solving the problem that the optical glass used to seal the identification device will be damaged when the material to be sorted comes into contact with it.

[0005] The technical solution of this utility model is as follows: a sealing mechanism for a multi-layer color sorter, including a glass assembly and a connecting frame with one open end. The glass assembly enters the inner side of the connecting frame through the open end. The glass assembly and the connecting frame are bolted together. An inflation chamber and an exhaust chamber are respectively provided on the upper and lower sides of the connecting frame. An inflation nozzle and an exhaust pipe are respectively provided on the same side of the inflation chamber and the exhaust chamber. The inflation nozzle is connected to a gas source, and the exhaust pipe is connected to an intermediate processing device. A through groove is opened on one side of the bottom of the inflation chamber. A guide plate A is provided on the outside of the through groove. A receiving interface is provided on the side of the exhaust chamber corresponding to the through groove. A guide plate B is provided on the outside of the receiving interface. The inflation nozzle of the inflation chamber injects gas into the inflation chamber, increasing the gas pressure in the inflation chamber. During this process, the gas is discharged outward along the through groove to form an air curtain. As the air curtain moves downward, it covers the glass assembly and enters the exhaust chamber along the receiving interface.

[0006] Furthermore, the connecting frame consists of two horizontally arranged horizontal plates with rails on opposite sides and a vertical plate connecting the two horizontal plates. The edges of both the horizontal and vertical plates are provided with bent portions extending towards the glass assembly. After the connecting frame is slidably connected to the glass assembly via the rails, it is fixed along the bend by bolts. The glass assembly can be assembled and disassembled without disassembling the connecting frame, and the installation of the glass assembly is ensured to be stable.

[0007] Furthermore, the through groove is vertically oriented towards the exhaust chamber and aligned with the receiving interface, ensuring that the gas discharged from the through groove will naturally approach the exhaust chamber and enter the receiving interface during its movement.

[0008] Furthermore, the guide plate A is a plate-shaped structure with a toothed inner wall distributed along the through groove, which enhances the stability of the airflow after passing through the guide plate A.

[0009] Furthermore, the guide plate B is a plate-shaped structure with its ends bent away from the exhaust chamber, increasing the opening diameter of the receiving interface to ensure that the airflow can be fully received.

[0010] Furthermore, the opening width of the receiving interface is greater than the opening width of the through groove.

[0011] Furthermore, the air inlet and air outlet on the surface of the exhaust chamber and the air inlet are located on the side near the opening of the connecting frame.

[0012] The beneficial effects of this utility model are as follows:

[0013] 1. This utility model simplifies the loading and unloading of the glass assembly by fixing it with a connecting frame, and facilitates subsequent inspection and maintenance. An inflation chamber and an exhaust chamber are respectively set on the upper and lower sides of the connecting frame. Gas is discharged outward along the through groove to form an air curtain. As the air curtain moves downward, it covers the glass assembly and enters the exhaust chamber along the receiving interface. The air curtain covering the glass assembly can block the selected materials that approach the glass assembly and restrict the movement path of the air curtain, thereby preventing the air curtain from affecting the normal movement of the selected materials.

[0014] 2. The toothed inner wall of the air passage of the inflation chamber of this utility model can restrict the airflow discharged from the inflation chamber and increase the control of the airflow. The exhaust pipe of the exhaust chamber is not directly connected to the external environment. An intermediate processing device such as a buffer device is set to prevent scattered materials from being carried into the exhaust chamber by the air curtain. Attached Figure Description

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0020] Example 1, such as Figure 1-3 As shown, a sealing mechanism for a multi-layer color sorter includes a glass assembly 1 and a connecting frame 2 with one end open. The glass assembly 1 enters the inner side of the connecting frame 2 along the open end of the connecting frame 2. The glass assembly 1 and the connecting frame 2 are bolted together. The connecting frame 2 consists of two horizontally arranged horizontal plates with rails on opposite sides and a vertical plate connecting the two horizontal plates. The edges of the horizontal plates and the vertical plate are provided with bent portions extending toward the glass assembly 1. The connecting frame 2 is slidably connected to the glass assembly 1 through the rails and then fixed along the bends by bolts.

[0021] The upper and lower sides of the connecting frame 2 are respectively provided with an inflation chamber 3 and an exhaust chamber 4. An inflation nozzle and an exhaust pipe are respectively provided on the same side of the inflation chamber 3 and the exhaust chamber 4. The inflation nozzle is connected to the air source, and the exhaust pipe is connected to the intermediate processing device. A through groove 5 is opened on one side of the bottom of the inflation chamber 3. A guide plate A6 is provided on the outside of the through groove 5. The guide plate A6 is a plate structure with a toothed inner wall distributed along the through groove 5 to enhance the stability of the airflow after passing through the guide plate A6. A receiving interface 7 is provided on the side of the exhaust chamber 4 corresponding to the through groove 5. The through groove 5 is perpendicular to the exhaust chamber 4. The through groove 5 is aligned with the receiving interface 7 to ensure that the gas discharged from the through groove 5 will naturally approach the exhaust chamber 4 and enter the receiving interface 7 during the movement process. The opening width of the receiving interface 7 is larger than the opening width of the through groove 5. A guide plate B8 is provided on the outside of the receiving interface 7. The guide plate B8 is a plate structure with the end bent away from the exhaust chamber 4 to increase the opening diameter of the receiving interface 7 to ensure that the airflow can be fully received.

[0022] The inflation nozzle of the inflation chamber 3 injects gas into the inflation chamber 3, increasing the air pressure inside the inflation chamber 3. During this process, the gas is discharged outward along the through groove 5 to form an air curtain. As the air curtain moves downward, it covers the glass assembly 1 and enters the exhaust chamber 4 along the receiving interface 7. The inflation nozzle and exhaust pipe on the surface of the exhaust chamber 4 and the inflation chamber 3 are located on the side near the opening of the connecting frame 2.

[0023] The working principle of this utility model is as follows: First, when using it, install the connecting frame 2, which has an inflation chamber 3 and an exhaust chamber 4 on the upper and lower sides, in the required position. Then, insert the glass assembly 1 through the opening of the connecting frame 2 and fix the glass assembly 1 with bolts. Then, the operator connects the air source and the intermediate processing equipment to the inflation chamber 3 and the exhaust chamber 4 respectively.

[0024] Gas is introduced into the inflation chamber 3 by the gas source. After the inflation chamber 3 is filled, the gas is discharged to the exhaust chamber 4 along the through groove 5. During this process, the airflow passes through the guide plate A6 and is constrained by the guide plate A6 to form an air curtain. As the air curtain moves downward, it comes into contact with the guide plate B8 set on the surface of the exhaust chamber 4 and enters the exhaust chamber 4 through the receiving interface 7 under the restriction of the guide plate B8. The gas that enters the exhaust chamber 4 enters the intermediate processing equipment through the exhaust pipe and is discharged outward. The air curtain between the inflation chamber 3 and the exhaust chamber 4 is formed close to the glass assembly 1 to protect the glass assembly 1. Even if materials approach the glass assembly 1, they will quickly leave under the action of the air curtain.

[0025] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
