Description

Technical Field

[0001] The utility model relates to the field of fertilizer processing, in particular to a nitric acid phosphate melt slurry drum granulation device. Background Technique

[0002] Nitric acid phosphate plays an important role in the growth and development of plants. It can provide nutrients, promote plant metabolism and enhance stress resistance. It is a commonly used multi-effect chemical fertilizer. During the granulation process of nitric acid phosphate, nitric acid, phosphoric acid and carriers are usually mixed and then put into the granulator, and then the granulator is started to complete the manufacturing.

[0003] At present, during the process of processing nitric acid phosphate by a granulator, the fertilizers inside the machine may agglomerate or form lumps. At this time, the particles will be closely connected to each other, making it difficult to fully dissolve and disperse. Therefore, when applied, the agglomerated or lumped nitric acid phosphate may cause problems such as uneven nutrient release and low absorption efficiency. In addition, the agglomerated and lumped nitric acid phosphate cannot be effectively treated, which may cause the direct loss or leakage of nitric acid phosphate into the environment, thus causing environmental pollution problems. Therefore, a nitric acid phosphate melt slurry drum granulation device is proposed for the above problems. Content of the Utility Model

[0008] Preferably, a groove is formed at the bottom end of the connecting rod, the rotating rods are vertically overlapped inside the groove, and counterweights are fixedly installed at the opposite ends of the two rotating rods. When the connecting rod rotates, the two rotating rods will rotate and move away from each other under the action of centrifugal force on the counterweights.

[0009] Preferably, the dispersing assembly includes a fixing plate fixedly installed on the surface of the fixed rod. The bottom end of the side of the fixing plate away from the fixed rod is slidably connected with a rotating ring.

[0023] The following is a further detailed description of the present application in conjunction with the attached Figures 1-6 This application will be further described in detail below.

[0024] The embodiment of the present application discloses a nitric acid phosphate melt slurry drum granulation device. Refer to Figure 1 , a nitric acid phosphate melt slurry drum granulation device, including granulation equipment 1, the output shaft of a motor 2 is fixedly connected to the bottom end of the granulation equipment 1, a fixed sleeve 3 is rotatably connected to the surface of the granulation equipment 1, a screening component 4 is arranged inside the granulation equipment 1, and a dispersing component 5 is arranged on the surface of the screening component 4;

[0025] Refer to Figures 2-4, the screening component 4 includes a fixed rod 41 fixedly installed on the bottom wall of the granulation device 1. A screen 42 is fixedly installed on the surface of the fixed rod 41. A fixing ring 43 is fixedly installed on the surface of the fixed rod 41. A connecting rod 44 is fixedly installed on the surface of the fixing ring 43. The bottom of the end of the connecting rod 44 away from the fixing ring 43 is fixedly installed with a vertical rod 45. The bottom of the vertical rod 45 is rotatably connected to a sliding rod 46. The side wall of the screen 42 is attached to and rotatably connected to the inner wall of the granulation device 1. The sliding rod 46 is slidably connected to the top of the screen 42. The sliding rod 46 slides on the top of the screen 42, thereby accelerating the efficiency of the nitrophosphate passing through the screen 42. The bottom end of the connecting rod 44 is rotatably connected to two rotating rods 47. A groove is provided at the bottom end of the connecting rod 44. The rotating rods 47 are vertically overlapped and located inside the groove. Counterweight blocks are fixedly installed at the opposite ends of the two rotating rods 47. When the connecting rod 44 rotates, the two rotating rods 47 will rotate and move away from each other under the action of the centrifugal force on the counterweight blocks. A buffer spring 48 is fixedly connected between the two rotating rods 47.

[0026] Referring to Figures 5-6 , the dispersing component 5 includes a fixing plate 51 fixedly installed on the surface of the fixed rod 41. The bottom end of the side of the fixing plate 51 away from the fixed rod 41 is slidably connected to a rotating ring 52. The cross-sectional shape of the bottom end of the side of the fixing plate 51 away from the fixed rod 41 is circular. A sliding groove adapted to the fixing plate 51 for sliding connection is provided at the top of the rotating ring 52. The cross-sectional shape of the sliding groove is circular. The connection between the fixing plate 51 and the rotating ring 52 can slide stably. An opening 53 is provided at the bottom end of the rotating ring 52. A stirring rod 54 is rotatably connected inside the opening 53. A torsion spring 55 is fixedly installed on the end face at the top of the stirring rod 54. The rotating ring 52 is located below the screen 42. One end of the torsion spring 55 away from the stirring rod 54 is fixedly connected to the inner wall of the opening 53. After the fixed rod 41 rotates, the stirring rod 54 twists the torsion spring 55 and rotates. At this time, the stirring rod 54 rotates below the screen 42, thereby dispersing the nitrophosphate passing through the screen 42 and further avoiding the caking of the nitrophosphate.

[0027] Working principle: After the operator fixes the fixed sleeve 3 and the motor 2, the raw materials are put into the interior of the granulating device 1. Then, the motor 2 is driven to drive the granulating device 1 to rotate. At this time, the granulating device 1 rotates inside the fixed sleeve 3 and rotates stably under the support of the fixed sleeve 3. The raw materials are granulated inside the granulating device 1. When the granulating device 1 drives the fixed rod 41 to rotate, the connecting rod 44 will rotate accordingly. Then, the rotating rod 47 at the bottom of the connecting rod 44 also rotates accordingly. At this time, the counterweight blocks on the surface of the rotating rod 47 are subject to a large centrifugal force due to their large weight. Therefore, the two rotating rods 47 start to rotate. At this time, the two rotating rods 47 stretch the buffer springs 48 and rotate in the direction away from each other. Therefore, at this time, the two rotating rods 47 are unfolded outside the grooves opened at the bottom of the connecting rod 44. Then, the particles that fall into the interior of the granulating device 1 are initially broken up by the unfolded rotating rods 47. Then, the broken-up particles fall onto the surface of the sieve mesh 42. The appropriately sized particles will pass through the sieve mesh 42. When the fixed rod 41 drives the fixed plate 51 to rotate, since the rotating ring 52 is not affected by the rotation of the fixed rod 41, at this time, the rotating ring 52 is only subject to the frictional force of the fixed plate 51. At this time, the rotating ring 52 will rotate under the action of the frictional force of the fixed plate 51, and the rotation speed of the rotating ring 52 is lower than that of the fixed plate 51 at this time. During the rotation of the rotating ring 52, the rotating ring 52 will drive the stirring rod 54 to rotate. At this time, the stirring rod 54 will rotate to an approximately horizontal state under the action of the centrifugal force. During the rotation of the stirring rod 54, the torsion spring 55 will be twisted to accumulate elastic force. At this time, the stirring rod 54 that rotates with the rotating ring 52 will rotate relative to the sieve mesh 42. Then, the calcium nitrate phosphate fertilizer that passes through the sieve mesh 42 is further broken up by the stirring rod 54, thus avoiding the phenomenon of calcium nitrate phosphate fertilizer caking.

[0028] After the operator, the operator discharges the particles through the discharge port at the bottom of the granulating device 1. During the process of breaking up the particles, there will be small-particle materials that do not meet the standards. The operator can collect and reprocess the small-particle materials to avoid waste of materials.

[0029] The above shows and describes the basic principles, main features and advantages of the present utility model. Those skilled in the art of this industry should understand that the present utility model is not limited by the above embodiments. What is described in the above embodiments and the specification only illustrates the principles of the present utility model. Without departing from the spirit and scope of the present utility model, the present utility model will have various changes and improvements, and these changes and improvements all fall within the scope of the present utility model claimed.
