Technical Field

[0001] The utility model belongs to the technical field of fertilizer production, and in particular relates to a size selection device for ammonium sulfate granular fertilizer. Background Art

[0002] Ammonium sulfate fertilizer is suitable for a variety of soils and crops. It can make plant branches and leaves grow vigorously, improve fruit quality and yield, and enhance the resistance of crops to disasters. It can be used as base fertilizer, topdressing and seed fertilizer. Ammonium sulfate is also widely used in industry, such as in medicine, food processing, chemical reagents, battery production, etc. In addition, it is also used in rare earth mining, extracting rare earth elements from mineral soils through ion exchange.

[0003] When fertilizers are granulated, some small particles that do not meet the batch specifications will be produced. After the small particles that do not meet the batch specifications are screened out and filled, they are sold according to the small particle specifications. Most of the existing screening devices are vibrating screen structures, but they cannot flatten the materials during the screening process, which may cause material accumulation during the vibration process when there are a lot of materials, making some small particles unable to be screened out, affecting the stability of the screening effect.

[0004] In view of this, the present utility model is proposed. Utility Model Content

The following embodiments are used to illustrate the utility model.

[0025] A device for selecting the size of ammonium sulfate granular fertilizer, such as Figure 1-2 As shown, it includes a mounting frame 10, and a screening assembly 20 for sorting the size of granular fertilizer is arranged between the inner walls on both sides of the mounting frame 10, and the screening assembly 20 is installed in a vertical sliding fit with the inner wall of the mounting frame 10;

[0028] like Figure 2 , Figure 4As shown, sub-sieve holes are provided between the top of the top plate 21 and the bottom 22 , the top plate 21 is located at the opening end of the mounting frame 10 and is equipped with a discharge hopper 1 24 , and the bottom 22 is located at the opening end of the mounting frame 10 and is equipped with a discharge hopper 2 25 .

[0029] like Figure 2-4 As shown, fixed plates 50 are fixedly connected at both ends between the inner walls of both sides of the mounting frame 10 and below the bottom 22 , and the elastic structure includes a plurality of elastic units, and the elastic units are evenly spaced and arranged in a linear array between the two fixed plates 50 and the bottom 22 .

[0030] like Figure 2-4 As shown, the elastic unit includes a telescopic rod 61 and a spring 62 . The telescopic rod 61 is vertically fixedly connected between the top of the fixing plate 50 and the bottom 22 , and the spring 62 is cooperatively installed on the outer side of the circumference of the telescopic rod 61 .

[0031] Its function is that when the device is used, the vibrator 40 switch is turned on to make the screening component 20 vibrate, and then the material is added from the top of the top plate 21, so that the smaller particles in the material that do not meet the requirements pass through the sieve holes on the top plate 21 under the action of vibration and fall into the bottom 22.
