Description

Technical Field

[0001] This utility model relates to the field of tracked color sorters, and in particular to a vibrating screen device for primary material selection. Background Technology

[0002] Tracked color sorters are devices that automatically separate discolored particles from granular materials based on differences in their optical properties using photoelectric detection technology. They are widely used in industries such as food, pharmaceuticals, renewable resources, and mining. In the processing of materials such as ores and glass, to ensure effective color sorting, a vibrating screen is used to initially remove dust and impurities before color sorting. Existing vibrating screens use vibrating springs or spring plates to support the vibrating disc, with the screen connected to the disc via bolts or welding. The material jumps forward under the excitation force generated by the vibrating motor and the support of the springs, allowing some dust and smaller impurities to pass through the screen mesh, achieving a preliminary screening effect. However, due to the complex connection method between the screen and the vibrating disc, quick disassembly and replacement of the screen are difficult, resulting in poor compatibility with different screen types for various materials. Furthermore, bolts are needed for secondary fixation of the vibrating disc during transportation. On the other hand, using springs or leaf springs to connect the frame and the vibrating plate results in poor stability. During transportation, the leaf springs or leaf springs will wobble with the vibrating plate, leading to increased noise during operation and poor stability and fatigue performance of the device. Therefore, how to make the screen in the vibrating screen device easier to replace and reduce wobbling and noise is a technical problem that needs to be solved. Utility Model Content

[0003] The purpose of this invention is to overcome the defects of the prior art and provide a vibrating screen device for preliminary material selection. By using a vertical quick clamp to fix the screen and the vibrating plate, and using an elastic shock-absorbing support to connect the frame and the vibrating plate, the screen replacement process is simplified, the resonance phenomenon during device start-up and shutdown is reduced, and the device is more stable during normal operation.

[0004] The objective of this utility model can be achieved through the following technical solutions:

[0005] According to one aspect of the present invention, a vibrating screen device for preliminary material selection is provided, comprising: a screen, a vertical quick clamp, a vibrating plate, a frame, and an elastic shock-absorbing support;

[0006] The screen is provided with a screen bend and flange at the edge, and the vibratory plate is provided with a vibratory plate bend and flange at the edge; the vertical quick clamp clamps the screen bend and flange to fix the screen on the vibratory plate; the vibratory plate is fixed to the frame mounting block at the upper end of the frame by elastic shock absorption support.

[0007] The first fixed base of the vertical quick clamp is welded to the bent flange of the vibratory feeder, and a mounting hole is opened on the first fixed base.

[0008] The vertical quick clamp is fixed to the first fixed base by bolts.

[0009] The vibratory feeder has a vibratory feeder mounting bracket welded to each of its four corners and bottom.

[0010] The elastic shock-absorbing support is composed of a first support rod, a connecting block, and a second support rod connected together, with the first and second support rods set at an angle.

[0011] The upper end of the first support rod is fixed to the vibratory feeder mounting frame via a connector to bear the vibration of the vibratory feeder.

[0012] The lower end of the second support rod is fixed to the frame by a connector.

[0013] The vibratory motor is fixed to the bottom of the vibratory plate.

[0014] The front end of the screen is provided with a discharge hopper for the material after primary screening.

[0015] The front end of the discharge hopper is a tracked color sorting device, and the lower outlet is equipped with a container to collect dust and impurities.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] (1) Simplify the screen replacement process and improve compatibility: The screen is fixed on the vibrating plate by clamping the screen with vertical quick clamps and bending and flipping the edges. There is no need for complicated disassembly and installation process. The screen can be replaced quickly by simply loosening or tightening the vertical quick clamps. This not only saves time and manpower for screen replacement, but also improves the compatibility with different screen models, making the device suitable for screening more types of materials.

[0018] (2) Improved stability of the device: The frame and vibratory plate are connected by an elastic damping support. The elastic damping support is composed of a first support rod, a connecting block and a second support rod. The first support rod and the second support rod are inclined. This structure can effectively reduce the resonance phenomenon when the device starts and stops, making the device more stable during normal operation. At the same time, the inclined support rod can also provide better support force, further enhancing the stability of the device. Therefore, no additional fixing device is needed during transportation.

[0019] (3) Reduced shaking and noise of the device: Traditional vibrating screen devices use springs or springs to connect the frame and the vibrating plate, which easily generates shaking and noise. The elastic damping support structure used in this device can better absorb and disperse vibration energy, reducing the shaking amplitude of the device. At the same time, due to the reduction of shaking, the noise of the device is also reduced, improving the comfort of the working environment. Attached Figure Description

Detailed Implementation

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some, not all, of the embodiments of the present utility model. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of the present utility model.

[0024] Before color sorting materials, a vibrating screen is needed to remove dust and small impurities to ensure accuracy. Existing vibrating screen structures use spring plates or springs to support the vibrating disc, with the screen mesh connected to the disc via bolts or welding. Using spring plates or spring supports results in poor stability, causing swaying during transport and requiring secondary fixing, which is then removed after transport. Furthermore, poor stability leads to high operating noise and poor fatigue performance. The screen mesh connection method also makes it difficult to easily adapt to different material requirements by simply replacing the screen mesh. In this embodiment, an elastic shock-absorbing support 2-2 is used to support the vibrating disc, and a vertical quick-clamping clamp 1-2 is used to hold the screen, achieving stability and easy replacement.

[0025] like Figure 1As shown, a vibrating screen device for preliminary material selection includes: a screen 1-1, a vertical quick-clamping device 1-2, a vibrating plate 1-3, a frame 2-1, and an elastic damping support 2-2; a screen bend flange 1-1-1 is provided at the edge of the screen 1-1, and a vibrating plate bend flange 1-3-1 is provided at the edge of the vibrating plate 1-3; the vertical quick-clamping device 1-2 clamps the screen bend flange 1-1-1, fixing the screen 1-1 to the vibrating plate 1-3; the vibrating plate 1-3 is fixed to the frame mounting block 2-1-1 at the upper end of the frame 2-1 by the elastic damping support 2-2. Figure 2 The diagram shows the combined structure of screen 1-1 and vibrating plate 1-3. Using the vertical quick clamp 1-2, screen 1-1 can be quickly replaced by loosening or tightening the clamp when the material has different size requirements. This saves time and manpower for screen replacement and improves compatibility with different screen models.

[0026] The first fixed base of the vertical quick clamp 1-2 is welded to the bent and flanged edge of the vibratory feeder 1-3-1, and a mounting hole is opened on the first fixed base. The vertical quick clamp 1-2 is fixed to the first fixed base by bolts. A vibratory feeder mounting bracket 1-3-2 is welded to the four corners of the vibratory feeder 1-3 on its side and bottom surfaces.

[0027] The elastic damping support 2-2 consists of a first support rod, a connecting block, and a second support rod connected together. The first and second support rods are inclined, while the connecting block is vertically positioned between them. The upper end of the first vibration rod is fixed to the vibratory feeder mounting frame 1-3-2 via a connector, bearing most of the vibration of the vibratory feeder 1-3. The lower end of the second support rod is fixed to the frame 2-1 via a connector. The elastic damping support 2-2 provides elastic support for the vibratory feeder 1-3, effectively isolating vibrations. It has a very low natural frequency, controlling the vibratory feeder 1-3 to move only in a straight line without yaw, allowing for quick and smooth start and stop of the vibratory feeder 1-3, rapid passage through the resonance zone, reduced noise, and improved fatigue performance. Furthermore, due to its high stability, no additional fixing mechanism is required during transportation.

[0028] The vibrating motor 2-3 is fixed to the bottom of the vibrating plate 1-3. The front end of the screen 1-1 is provided with a discharge hopper 2-4 for discharging the material after primary screening. The front end of the discharge hopper 2-4 is a tracked color sorting device, and the lower outlet is provided with a container to collect dust and impurities.

[0029] In the use and installation of the vibrating screen device in this embodiment, the size of the screen 1-1 is selected according to the material to be selected, and it is clamped onto the vibrating plate 1-3 using a vertical quick clamp 1-2. The elevator transports the material to be selected to the screen surface of the screen 1-1 of the vibrating screen device, the vibrating motor 2-3 generates excitation force, and the elastic damping support 2-2 supports the vibration of the vibrating plate 1-3. Dust and small impurities in the material fall onto the vibrating plate 1-3 through the screen 1-1, and are further screened out from the lower outlet of the discharge hopper 2-4. The material after the initial screening is sent from the front outlet of the discharge hopper 2-4 to the crawler color sorter for the next screening.

[0030] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any person skilled in the art can easily conceive of various equivalent modifications or substitutions within the technical scope disclosed in this utility model, and these modifications or substitutions should all be covered within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the scope of the claims.
