Technical Field

[0001] This utility model relates to the technical field of screening devices for blended fertilizers, specifically a screening device for the production of blended fertilizers. Background Technology

[0002] Blended fertilizer is a compound fertilizer made by mixing two or more fertilizers in a certain proportion. It usually contains two or three elements from nitrogen, phosphorus and potassium. It has the characteristics of comprehensive nutrients, flexible formula and low production cost. It is suitable for soil testing and formula fertilization and can meet the nutritional needs of different soils and crops.

[0003] Currently, in existing technologies, blended fertilizers form particles of varying sizes during the mixing process. Larger particles can easily clog the filter screen and cause uneven fertilization, thus affecting product quality. Therefore, there is a need to propose a screening device for blended fertilizer production. Utility Model Content

[0022] 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 embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.

[0023] The following is in conjunction with the appendix Figure 1-5 This application will be described in further detail.

[0024] This application discloses a screening device for blended fertilizer production. (Refer to...) Figures 1-5 A screening device for blended fertilizer production includes a fixed frame 1, an annular frame 11 fixedly connected to the top of the fixed frame 1, a spring 2 fixedly connected to the top of the annular frame 11, and a screening mechanism 3 set on the top of the spring 2. By using the fixed frame 1 to support the annular frame 11, the annular frame 11 and the spring 2 cooperate to support the screening mechanism 3. The elastic force of the spring 2 causes the screening mechanism 3 to vibrate during operation, thereby improving the screening efficiency. The blended fertilizer is filtered and screened by the screening mechanism 3. At the same time, the screening mechanism 3 will first crush the larger particles of blended fertilizer, and discharge the uncrushable particles, thereby improving the screening effect and the anti-clogging effect. In specific implementation, the fixed frame 1 needs to be fixed on the conveying device to facilitate the introduction of the filtered and uniform blended fertilizer into the next processing procedure.

[0025] The screening mechanism 3 includes a support frame 31, which is fixedly connected to the top of the spring 2. A filter chamber 32 is rotatably connected to the top of the support frame 31. A first motor 39 is installed on one side of the support frame 31, driving the filter chamber 32 to rotate. A first filter screen 33 is installed on the top of the filter chamber 32, and a second filter screen 34 is installed at the bottom of the filter chamber 32. A discharge port 314 is installed on the axis of the second filter screen 34. A guide roller 312 is installed on the upper surface of the first filter screen 33, and an anti-clogging brush 313 is installed on the upper surface of the second filter screen 34. A second motor 311 is installed on the top of the support frame 31, driving the guide roller 312 and the anti-clogging brush 313 to rotate. By introducing the blended fertilizer into the top of the filter chamber 32, small particles and powdery substances are mixed. Fertilizer enters the filter chamber 32 through the first filter screen 33 and falls onto the second filter screen 34. Larger particles of impurities are crushed by the guide roller 312 driven by the second motor 311 before entering the filter chamber 32 through the first filter screen 33 and falling onto the second filter screen 34. The second filter screen 34 has an inverted conical vertical cross section. Powdered blended fertilizer is drawn out through the second filter screen 34, while granular blended fertilizer is drawn out through the feed port 314 under its own gravity, thereby achieving the purpose of screening out uniform powdered blended fertilizer. The first motor 39 drives the filter chamber 32 to rotate, which speeds up the screening efficiency of the filter chamber 32. The second motor 311 drives the anti-clogging brush 313 to rotate in contact with the surface of the second filter screen 34 to prevent granular blended fertilizer from clogging the second filter screen 34.

[0026] Reference Figure 1 , Figure 2 and Figure 3 A rotating frame 36 is fixedly connected to the outer wall of the filter chamber 32. The rotating frame 36 is rotatably connected to the top of the support frame 31. A first gear 37 is fixedly connected to the outer wall of the rotating frame 36. A second gear 38 is fixedly connected to the output end of the first motor 39. The first gear 37 and the second gear 38 mesh. The first motor 39 drives the second gear 38 to rotate. The second gear 38 drives the first gear 37 to rotate. The first gear 37 drives the rotating frame 36 to rotate. The rotating frame 36 rotates stably on the support frame 31 and drives the filter chamber 32 to rotate. The rotation of the filter chamber 32 causes the blended fertilizer to tumble, thereby accelerating the filtration of the blended fertilizer.

[0027] Reference Figure 3 , Figure 4 and Figure 5A bracket 310 is fixedly connected to the top of the support frame 31. A second motor 311 is fixedly connected to the top of the bracket 310. The output end of the second motor 311 extends into the inner cavity of the filter chamber 32. A conical plate 35 is fixedly connected to the inner side of the first filter screen 33. The outer wall of the guide roller 312 contacts the upper surface of the conical plate 35. One end of the guide roller 312 is fixedly connected to the output end of the second motor 311. One end of the anti-clogging brush 313 is fixedly connected to the output end of the second motor 311. The anti-clogging brush 313 contacts the upper surface of the second filter screen 34. A guide pipe 315 is rotatably connected to the bottom of the discharge port 314. One end of the guide pipe 315 extends obliquely out of the fixed... On the outside of the fixed frame 1, the guide roller 312 and the anti-clogging brush 313 are driven to rotate simultaneously by the second motor 311 on the bracket 310. The guide roller 312 rotates along the conical plate 35 on the inner side of the first filter screen 33 and crushes the large granular fertilizer on it. After crushing, the fertilizer falls from the first filter screen 33 into the filter chamber 32 along the inclined surface of the conical plate 35 under its own gravity. The anti-clogging brush 313 rotates along the surface of the second filter screen 34 to prevent the granular fertilizer from clogging the second filter screen 34. At the same time, the granular fertilizer and impurities are led out along the inner arc surface of the second filter screen 34 through the feed port 314 and the guide pipe 315.

[0028] Working principle: In specific implementation, the fixing frame 1 is fixed to the top of the conveying device, and the blended fertilizer is introduced into the screening mechanism 3. Large particles of blended fertilizer remain on the first filter screen 33, while small particles and powdered blended fertilizer enter the filter chamber 32 through the first filter screen 33 and fall onto the second filter screen 34. Then, the powdered blended fertilizer is led out through the second filter screen 34, and the granular blended fertilizer is led out through the inner arc surface of the second filter screen 34 via the feed port 314 and the guide pipe 315, thereby achieving the effect of uniform screening of blended fertilizer. The first motor 39 drives the second gear 38 to rotate, the second gear 38 drives the first gear 37 to rotate, and the first gear 37 drives the rotating frame 36 to rotate stably on the support frame 31. The rotating frame 36 drives the filter chamber 32 to rotate, and the rotation of the filter chamber 32 causes the blended fertilizer to tumble on the filter chamber 32, thereby improving the screening effect. The second motor 311 on the support 310 drives the guide roller 312 to rotate. The guide roller 312 rotates on the surface of the conical plate 35 and crushes the larger granular blended fertilizer particles retained on it. The crushed blended fertilizer then enters the filter screen through the first filter screen 33. At the same time, the anti-clogging brush 313 rotates with the second motor 311 and cleans the surface of the second filter screen 34 to prevent the granular blended fertilizer from clogging the second filter screen 34. The ring frame 11 and the spring 2 work together to make the filter chamber 32 vibrate when it is working, thereby further improving the filtration and screening efficiency of the blended fertilizer.
