Description

Technical Field

[0001] This utility model relates to the technical field of screening devices, and in particular to a dust removal and adjustment device for a hexagonal screen used in sand processing. Background Technology

[0002] In the mining industry, hexagonal screens are widely used as important screening equipment in casting, metallurgy, mining, and chemical industries. However, hexagonal screens generate a large amount of dust during the screening process, which not only pollutes the environment but may also affect the health of workers. To solve this problem, traditional hexagonal screens are usually equipped with dust removal devices. However, these dust removal devices generally have a problem: the air volume lacks an effective adjustment mechanism. Due to the lack of an adjustment mechanism, traditional dust removal devices often cannot adjust their working state according to actual needs. On the one hand, if the working intensity of the dust removal device is insufficient, it cannot effectively reduce dust. On the other hand, if the dust removal device is always kept at an excessively high working intensity, it will not only waste energy but may also affect the normal operation of the hexagonal screen due to excessive dust removal. Utility Model Content

[0003] To overcome the shortcomings of the existing problems mentioned above, this utility model provides a sand treatment hexagonal screen dust removal and adjustment device that can effectively control the air volume.

[0004] The technical solution adopted by this utility model to solve its technical problem is: a dust removal and adjustment device for a hexagonal sand screen, including a screening device. The top of the screening device is provided with a dust suction port, and the bottom of the screening device is provided with multiple air inlets. Air inlets are provided on both sides of the screening device, and air inlets are provided on the air inlets. The air inlet adjustment device includes a frame, the rear side of the frame is connected to the air inlet, the front end of the frame is connected to a mesh plate, and several rotating baffles are provided in the frame. The rotating baffles are arranged longitudinally in the frame. Connecting rods are provided at both ends of the rotating baffles. One end of the connecting rod is connected to both sides of the frame. The rotating baffles are rotatably mounted in the frame through the connecting rods. The connecting rod on one side of one of the rotating baffles passes through the bracket and is connected to the frame to provide a rotating handle. A pair of synchronizing rods are provided on the rear side of the rotating baffles. Several extension ends are provided on the synchronizing rods. The extension ends are respectively hinged to the rear side of each rotating baffle.

[0005] Preferably, the rotating handle includes a rotating end and a handle.

[0016] Any feature disclosed in this specification (including any appended claims, abstract, and drawings) may be replaced by other equivalent or similar features for a similar purpose, unless specifically stated otherwise. That is, unless specifically stated otherwise, each feature is merely one example of a series of equivalent or similar features.

[0017] according to Figures 1-5As shown, a dust removal and adjustment device for a hexagonal screen used in sand processing includes a screening device 1. The screening device 1 includes a hexagonal screen in the middle for screening materials and an outer shell. A dust suction port 2 is provided at the top of the screening device 1, and multiple air inlets 3 are provided at the bottom of the screening device 1. Air inlets 3 are provided on both sides of the screening device 1. An air inlet adjustment device 4 is provided on the air inlets 3. The air inlets 3 continuously supply air to the screening device 1, and the dust suction port 2 draws air to effectively remove the dust generated during the screening process. The air inlet adjustment device 4 is used to adjust the air intake of the air inlets. The air inlet adjustment device 4 includes a frame 41, the rear of which is connected to the air inlet 3, and a mesh plate 42 is connected to the front of the frame 41. Several rotating baffles 43 are provided in the frame 41, and the rotating baffles 43 are arranged longitudinally. The rotating baffle 43 is housed in the frame 41. Connecting rods 44 are provided at both ends of the rotating baffle 43. One end of each connecting rod 44 is connected to both sides of the frame 41. The rotating baffle 43 is rotatably mounted in the frame 41 via the connecting rods 44. A rotating handle 5 is provided on one side of one of the rotating baffles 43, extending through a bracket and connecting to the frame 41. Rotating the rotating handle 5 allows the connecting rod 44 to rotate, thus rotating the rotating baffle 43. A pair of synchronizing rods 45 are provided on the rear side of the rotating baffle 43. Several extension ends 46 are provided on the synchronizing rods 45, each hinged to the rear side of each rotating baffle 43. When the rotating baffle 43 connected to the rotating handle 5 rotates, the other rotating baffles 43 rotate synchronously.

[0018] The rotating handle 5 includes a rotating end 51 and a handle 52. The handle 52 extends from the rotating end 51. The rotating end 51 is located on one side of the frame 41 and is fixedly connected to the connecting rod 44. A limit groove 53 is provided on one side of the rotating end 51 at the connection point with the connecting rod 44. A scale is also provided on one side of the limit groove 53 for adjustment. The limit groove 53 is an arc-shaped structure. A limit shaft 54 ​​is provided in the limit groove 53. One end of the limit shaft 54 ​​is connected to the frame 41. A locking block 55 is provided at the other end of 54. The locking block 55 is located on the outside of the rotating handle 5. The limiting groove 53 cooperates with the limiting shaft 54 ​​to limit the rotation range of the rotating handle 5. The limiting shaft 54 ​​is provided with threads. The locking block 55 is a collar with threads on the inner side. The collar is provided with paddles on both sides for easy rotation. The locking block 55 is located on the limiting shaft 54. By rotating the limiting shaft 54, the locking block 55 can be pressed on the rotating end 51, thereby fixing the rotation of the rotating handle 5.

[0019] The side section of the frame 41 is H-shaped, which facilitates the installation of the air intake adjustment device 4.

[0020] In practical application, the materials to be screened are screened in the screening device 1. A blower is connected to the air inlet 3 and the air inlet regulating device 4 through pipes to blow air into the screening device 1. Then, a dust collection device is connected to the dust collection port 2 to collect dust and complete the dust removal work. The air inlet regulating device 4 is operated by the operator to rotate the handle 52, so that the rotating end 51 rotates around the connecting rod 44, thereby driving the connecting rod 44 and the rotating baffle 43 to rotate. When one rotating baffle 43 rotates, the other rotating baffles 43 can be rotated synchronously through the synchronizing rod 45 to adjust the air intake of the air inlet 3. Then, by rotating the locking block 55, the rotation of the rotating handle 5 can be fixed.

[0021] This design is ingenious. By setting up an air intake adjustment device, the air intake volume can be effectively adjusted according to actual needs, ensuring that the air intake volume is always kept at the optimal state. This avoids the impact of excessive or insufficient air volume on material screening and dust removal, enabling the dust removal device to adapt to different working environments and needs, and improving the flexibility and adaptability of the equipment.

[0022] This invention is not limited to the specific embodiments described above. This invention extends to any new feature or combination disclosed in this specification, as well as any new method or process step or combination disclosed herein.
