Technical Field

[0001] This utility model relates to the field of flour sieving technology, and in particular to a vibrating screen with an adjustable structure. Background Technology

[0002] Vibrating screens are commonly used in flour processing to sift flour, remove impurities, and ensure flour quality. However, during the sieving process, we found that because flour particles are relatively light, the vibration of the screen easily causes flour to splatter, resulting in material waste, pollution of the working environment, and difficult cleaning. Utility Model Content

[0018] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0019] like Figure 1-4 As shown, a vibrating screen with an adjustable structure includes a support column 1, a feeding mechanism 2 is provided on the upper part of the support column 1, and a screening mechanism 4 is connected to the lower part of the feeding mechanism 2 through a flexible connecting cloth 3.

[0020] In this embodiment, the feeding mechanism 2 includes a feeding shell 201, a central shaft 202, an isolation plate 203, and a reduction motor 204. The front and rear ends of the central shaft 202 are rotatably connected to the middle of the feeding shell 201. One end of multiple isolation plates 203 is fixedly connected at equal intervals to the outer periphery of the central shaft 202. The outer periphery of the isolation plates 203 is in contact with the inner sidewall of the feeding shell 201. The reduction motor 204 is installed on the outside of the feeding shell 201. The output end of the reduction motor 204 passes through the sidewall of the feeding shell 201 and is fixedly connected to one end of the central shaft 202.

[0021] Specifically, the drive geared motor 204 causes the central shaft 202 to rotate the isolation plate 203, thereby causing the flour in the upper part to be conveyed downwards. At least two isolation plates 203 always separate the feed shell 201 into upper and lower areas to prevent the flour from splashing upwards during screening and feeding.

[0022] In this embodiment, the screening mechanism 4 includes a screening cylinder 401, a screening component 402, a retaining ring 403, a fastener 404, and a vibrating motor 405. The upper end of the screening cylinder 401 is fixedly connected to the lower end of the flexible connecting cloth 3. The retaining ring 403 is installed at the lower end of the screening cylinder 401 through the fastener 404. The screening component 402 is disposed between the screening cylinder 401 and the retaining ring 403. Multiple vibrating motors 405 are installed on the outer periphery of the screening cylinder 401. A spring 6 is disposed on the outer periphery of the screening cylinder 401, and the lower end of the spring 6 is disposed on the upper end of the column 5. The screening component 402 includes a metal filter screen 4021, multiple arc-shaped baffles 4022, and a diverting plate. 4023, the lower part of the diversion plate 4023 is fixedly connected to the upper end of the arc-shaped baffle 4022. Multiple arc-shaped baffles 4022 are arranged in concentric circles from the inside to the outside on the upper part of the metal filter screen 4021, and the metal filter screens 4021 on adjacent circles are staggered. The outer periphery of the metal filter screen 4021 is arranged between the screening cylinder 401 and the baffle ring 403. The diversion plate 4023 is conical, and the metal filter screen 4021 is inverted conical. A flexible feed pipe 1 406 is provided at the lower end of the baffle ring 403, and a flexible feed pipe 2 407 is provided at the lower end of the metal filter screen 4021. The lower end of the flexible feed pipe 2 407 passes through the flexible feed pipe 1 406.

[0023] Specifically, the vibration generated by the vibrating motor 405 causes the metal filter screen 4021 to sieve the flour. Multiple arc-shaped baffles 4022 block the flour, reducing the speed at which the flour moves towards the center of the metal filter screen 4021. This causes large flour particles to gradually move into the metal filter screen 4021 and finally be discharged through the flexible feed pipe 407. Meanwhile, qualified flour passes through the metal filter screen 4021 and is discharged through the flexible feed pipe 406.

[0024] Working principle:

[0025] The drive reduction motor 204 causes the central shaft 202 to rotate the isolation plate 203, thereby conveying the flour from the top downwards. At least two isolation plates 203 always separate the feed shell 201 into upper and lower areas to prevent the flour from splashing upwards during sieving and feeding, and to ensure continuous feeding and sieving. The vibration generated by the vibration motor 405 causes the metal filter screen 4021 to sieve the flour. Multiple arc-shaped baffles 4022 block the flour, reducing the speed at which the flour moves towards the center of the metal filter screen 4021. Large flour particles gradually move into the interior of the metal filter screen 4021 and are finally discharged through the flexible discharge pipe 2 407, while qualified flour passes through the metal filter screen 4021 and is discharged through the flexible discharge pipe 1 406.
