Description

Technical Field

[0001] This utility model relates to the field of powder processing equipment technology, and in particular to a powder screening and conveying device. Background Technology

[0002] In the field of powder material production and processing, precise screening of powder materials to remove impurities, ensure material purity, and achieve efficient material transport between various processes are key steps to ensure production quality and efficiency.

[0003] Currently, traditional powder screening and conveying equipment faces numerous problems in practical applications. In the material conveying stage, most equipment employs manual transfer or open pipeline conveying methods. Manual transfer is not only labor-intensive and inefficient, but also prone to generating large amounts of dust due to material spillage, polluting the working environment, endangering the health of operators, and wasting materials. Open pipeline conveying, on the other hand, makes it difficult to avoid dust leakage, similarly posing a threat to the working environment and production safety.

[0004] The existing equipment often has a cumbersome process in connecting the screening stage with subsequent storage and transportation. Screened materials need to be manually handled multiple times or transported in multiple discontinuous stages before entering the storage warehouse. Too many intermediate steps lead to poor production continuity and the material quality is easily affected by secondary contamination during transportation.

[0005] Furthermore, while commonly used vibrating discharge devices can achieve uniform material output when materials are discharged from the storage bin to subsequent processes, the impact force generated by the vibration can easily be transmitted to the storage bin and other related components through the connecting structure. Existing equipment's vibration damping measures are mostly simple spring connections, which are difficult to simultaneously mitigate the transmission of vertical and lateral vibrations. Long-term use can lead to loosening of components, accelerated wear, and shortened equipment lifespan. At the same time, vibration noise can also have an adverse impact on the working environment. Utility Model Content

[0006] The purpose of this invention is to solve the above-mentioned problems by providing a powder screening and conveying device.

[0007] The technical solution of this utility model is implemented as follows:

[0008] This utility model provides a powder screening and conveying device, the conveying device comprising:

[0009] Storage bins are used to store materials;

[0010] A three-dimensional vibrating screen is used to screen the material in the storage hopper, and the feed end of the three-dimensional vibrating screen is connected to the discharge end of the storage hopper.

[0011] A transfer hopper is used to store the material screened out from the three-dimensional vibrating screen, and the feed end of the transfer hopper is connected to the discharge end of the three-dimensional vibrating screen.

[0012] A transfer hopper is used to store the material in the transfer cylinder. The feed end of the transfer hopper is connected to the discharge end of the transfer cylinder. A linear vibrator is connected to the discharge end of the transfer hopper to discharge the material in the transfer hopper through vibration.

[0013] As a further improvement to the above technical solution:

[0014] The conveying device further includes:

[0015] The first vacuum feeder connects the feed end of the three-dimensional vibrating screen to the discharge end of the storage tank.

[0016] The discharge end of the first vacuum feeder is installed at the feed end at the top of the three-dimensional vibrating screen, and the suction end is connected to the discharge end at the bottom of the storage tank through the first conveying pipe.

[0017] The advantages or beneficial effects of the above technical solutions include at least the following:

[0018] 1. By leveraging the combined operation of a double vacuum feeder and a vibrating discharge structure, the entire process of material transfer from storage and screening to transfer and output is automated, significantly reducing manual intervention and making the production process smoother, better adapting to the needs of large-scale continuous production.

[0019] 2. The combination of springs and ring-shaped shock-absorbing rubber can effectively buffer both vertical and lateral vibration impacts, significantly reducing wear on the connecting parts between the transfer hopper and the vibrating discharge frame, and extending the overall maintenance cycle of the equipment.

[0020] 3. The fine screening of the three-dimensional vibrating screen combined with the fully sealed pipeline transmission not only avoids dust pollution, but also reduces secondary mixing of materials during the transfer process, effectively improving the purity of qualified materials; the uniform discharge design of the linear vibrator can ensure more stable material output and provide precise material supply for the next process.

[0021] 4. The vacuum feeder adopts the principle of negative pressure adsorption, which is more energy-efficient than traditional mechanical conveying methods; the modular design of each component makes it easy to inspect and replace individually, reducing the operation and maintenance costs of the equipment, while the vibration reduction structure reduces vibration and noise, which can further optimize the working environment.

[0032] Reference Figure 1 and Figure 2 A powder screening and conveying device, the conveying device comprising:

[0033] Storage bin 10 is used for storing materials;

[0034] A three-dimensional vibrating screen 20 is used to screen materials in a storage hopper 10. The inlet end of the three-dimensional vibrating screen 20 is connected to the outlet end of the storage hopper 10. Preferably, the inlet end of the three-dimensional vibrating screen 20 is connected to the outlet end of the storage hopper 10 through a first vacuum feeder 21. The discharge end of the first vacuum feeder 21 is installed at the inlet end at the top of the three-dimensional vibrating screen 20, and the suction end is connected to the discharge end at the bottom of the storage hopper 10 through a first conveying pipe 22. The first vacuum feeder 21 generates negative pressure to draw the material in the storage hopper 10 into the three-dimensional vibrating screen 20 through the first conveying pipe 22 for screening, ensuring that the material meets the process requirements.

[0035] The transfer cylinder 30 is used to store the material screened from the three-dimensional vibrating screen 20. The feed end of the transfer cylinder 30 is connected to the discharge end of the three-dimensional vibrating screen 20.

[0036] The intermediate hopper 40 is used to store the material in the intermediate hopper 30. The feed end of the intermediate hopper 40 is connected to the discharge end of the intermediate hopper 30. The feed end of the intermediate hopper 40 is connected to the discharge end of the intermediate hopper 30 through a second vacuum feeder 41. The discharge end of the second vacuum feeder 41 is installed at the feed end at the top of the intermediate hopper 40, and the suction end is connected to the discharge end at the bottom of the intermediate hopper 30 through a second conveying pipe 42. The second vacuum feeder 41 generates negative pressure to draw the material screened in the intermediate hopper 30 into the intermediate hopper for use. Then, the discharge end of the intermediate hopper 40 is connected to a linear vibrator 43 to discharge the material from the intermediate hopper 40 through vibration.

[0037] Based on the above, the linear vibrator 43 includes: a vibrating discharge frame 431, installed at the discharge end of the bottom of the transfer hopper 40; and a vibrator 432, installed at the bottom of the vibrating discharge frame 431, for vibrating the vibrating discharge frame 431.

[0038] Furthermore, the bottom discharge end of the transfer hopper 40 has a vertically downward extending connecting section 44, which is arranged in a cylindrical structure. The conveying device further includes:

[0039] The shock-absorbing component 50 connects the discharge end of the transfer hopper 40 at its bottom to the vibrating discharge frame 431. The shock-absorbing component 50 includes:

[0040] The connecting cylinder 51 is fixedly installed at the feed end of the vibrating discharge frame 431. The connecting cylinder 51 is sleeved on the outside of the connecting section 44 and can move up and down along the axial direction of the connecting section 44. The inner side of the connecting cylinder 51 and the outer side of the connecting section 44 have a gap, so that the connecting cylinder 51 can move closer to or further away from the connecting section 44 along the radial direction of the connecting section 44.

[0041] Spring 52 is sleeved on connecting section 44;

[0042] The inner side of the connecting cylinder 51 has an annular protrusion 511 in the middle, which divides the connecting cylinder 51 into upper and lower parts. There is a gap between the two parts and the outer side of the connecting section 44. Specifically, springs 52 are placed in the gaps. There are two springs 52, one spring 52 is placed in each gap. One end of the two springs 52 abuts against the annular protrusion 511, and the other end abuts against the protrusion of the connecting section 44. When the vibrator 432 generates vertical vibration in the height direction, the compression and extension of the springs 52 can reduce the impact of the vibrator 432 on the transfer hopper 40.

[0043] The damping assembly 50 further includes an annular damping rubber 53, installed at the inner edge of the annular protrusion 511, because vibration is not only in the vertical direction but may also occur laterally, such as... Figure 3As shown, there is a gap between the inner ring of the annular damping rubber 53 and the connecting section 44. This gap prevents the annular damping rubber 53 from clamping the connecting section 44, allowing for smoother vertical displacement and ensuring the damping effect.
