Description

Technical Field

[0001] This application relates to the field of pesticide production technology, and in particular to a granulation apparatus for the production of water-dispersible granules. Background Technology

[0002] Water-dispersible granules are an environmentally friendly pesticide formulation, and the granulation process is crucial in their production. Currently, commonly used wet granulation equipment typically includes a mixer, a granulator, and a dryer.

[0003] Regarding the aforementioned technologies, the inventors believe the following problems still exist: First, existing mixing devices mostly use a simple structure with a motor driving a straight rod stirring blade. This stirring method results in insufficient contact between raw materials of different components, low mixing uniformity, which in turn affects the quality of subsequent granulation. Some particles may even clump together during use due to insufficient dispersant content, resulting in uneven particle composition and poor mixing effect.

[0004] Secondly, the granulation of water-dispersible granules requires multiple processes, which leads to frequent transportation and poor granulation results. This not only wastes time but also increases the workload, thus resulting in poor performance.

[0005] To address the aforementioned problems, the inventors have proposed a granulation device for the production of water-dispersible granules, which solves these problems. Utility Model Content

[0006] In order to improve the problem that some existing devices are inconvenient to use, the purpose of this utility model is to provide a granulation device for the production of water-dispersible granules.

A mixing mechanism, a forming mechanism, and a screening mechanism are sequentially arranged from top to bottom on the top surface of the support frame. The forming mechanism is located between the mixing mechanism and the screening mechanism. The support frame is fixedly installed on the bottom surface of the screening mechanism. The mixing mechanism includes a mixing chamber. A top plate is fixedly installed on the top surface of the mixing chamber.

Two rotating shafts are rotatably installed between the inner walls on both sides of the installation groove. Granulation rollers are fixedly installed on the outer surfaces of the two rotating shafts. A control motor is fixedly installed on one outer surface of the molding chamber.

[0026] The output end of the drive motor 24 movably passes through the top plate 22 and is fixedly mounted with a rotating rod 26. The rotating rod 26 is used as prior art, so that the drive motor 24 drives the rotating rod 26 to rotate.

[0027] Multiple stirring blades 27 are fixedly installed on the outer surface of the rotating rod 26. The rotating rod 26 drives the stirring blades 27 to rotate, thereby mixing the water-dispersible granules.

[0028] A support ring 29 is fixedly installed on the inner wall of the mixing chamber 21. The cross-sectional shape of the support ring 29 is U-shaped, so that it can support the protruding teeth 28.

[0029] Multiple protruding teeth 28 are fixedly installed inside the support ring 29. The multiple protruding teeth 28 are distributed in a ring array on the inner wall of the support ring 29. The cross-sectional shape of the protruding teeth 28 is trapezoidal, which can apply shear force to the water-dispersible granules during stirring.

[0030] Multiple stirring blades 27 are located between multiple protruding teeth 28, which are arranged vertically so that the stirring blades 27 and the protruding teeth 28 work together to apply shear force to the water-dispersible granules and improve the mixing effect.

[0031] Multiple mixing chambers 21 are fixedly installed with inverted cone-shaped guide plates 20 at their bottom ends. The guide plates 20 are connected to the molding mechanism 3 and can discharge water-dispersible granules, thus facilitating their entry into the next stage.

[0032] The molding mechanism 3 includes a molding chamber 32, and both the upper and lower ends of the molding chamber 32 are equipped with valves that can be opened and closed. The valves are existing mature technologies and can control the delivery of water-dispersible granules.

[0033] The molding chamber 32 is fixedly installed on the bottom surface of the guide plate 20, so that the water-dispersible granules can directly enter the interior of the molding chamber 32.

[0034] The upper part of the forming chamber 32 is provided with a collection trough 34. The collection trough 34 is used as existing technology and can collect materials.

Granulation rollers 33 are fixedly installed on the outer surfaces of the two rotating shafts 37. The two rotating shafts 37 can support the granulation rollers 33 and drive them to rotate. The granulation rollers 33 are used in the prior art. Their outer surfaces are provided with multiple semi-circular grooves, which can be used to mold water-dispersible granules.

[0036] A control motor 31 is fixedly installed on one side of the outer surface of the forming chamber 32. The control motor 31 is used as prior art and can drive the rotating shaft 37 and the granulation roller 33 to rotate.

[0037] A support 38 is fixedly installed on one side of the molding chamber 32, and the control motor 31 is fixedly installed on the top surface of the support 38. The support 38 can support the control motor 31 to prevent it from falling off.

[0038] The output end of the control motor 31 moves through the molding chamber 32 and is fixedly connected to one of the rotating shafts 37. The ends of the two rotating shafts 37 away from the control motor 31 both rotate through the molding chamber 32 and are fixedly installed with gears 35. The two gears 35 mesh with each other. Through the two gears 35, the two rotating shafts 37 can rotate relative to each other, thereby driving the two granulation rollers 33 to rotate and extrude the water-dispersible granules.

[0039] The screening mechanism 4 includes a screening chamber 41, which serves as a shell. The top surface of the screening chamber 41 is provided with a conveying port 42 that works in conjunction with the forming chamber 32, allowing the water-dispersible granules to enter the interior of the screening chamber 41 through the conveying port 42.

[0040] An inclined screen 43 is fixedly installed inside the screening chamber 41. The screen 43 is used as existing technology and can filter and screen defective products.

[0041] The inner wall of the screening chamber 41 on the lower side of the screen 43 is provided with a through-type discharge port 44. Qualified products will be conveyed through the inclined screen 43 and discharged.

[0042] A drying chamber 47 is fixedly installed on the lower inner wall of the screening chamber 41. The drying chamber 47 is a shell structure, and hot air can circulate inside.

[0043] The drying chamber 47 is provided with multiple air outlets 45 on one side of the inclined side, which are used in conjunction with the screen 43. The air outlets 45 can discharge hot air to dry the water-dispersible granules on the top surface of the screen 43. At the same time, the air outlets 45 are provided with anti-clogging mesh to prevent material blockage.

[0044] The drying chamber 47 is connected to an air inlet pipe 46 on the side opposite to the air outlet 45. The air inlet pipe 46 is used in the prior art and can transport water-dispersible granules.

[0045] A cleaning plate 48 that can be opened and closed is provided on one side of the drying chamber 47. A handle 49 is fixedly installed on one side of the cleaning plate 48. The cleaning plate 48 can be opened to facilitate the unified treatment of the defective products accumulated inside.

[0046] Working principle: First, the device is supported by the bracket 1. Then, the cover plate 23 is opened and the material is fed into the mixing chamber 21 through the feed port 25. The drive motor 24 on the top surface of the top plate 22 is started, which drives the rotating rod 26 to rotate. The rotating rod 26 drives the stirring blade 27 to rotate. The stirring blade 27 mixes the water-dispersible granules. At the same time, the multiple protrusions 28 inside the support ring 29 block the flow and apply shear force to the water-dispersible granules, thereby improving the mixing effect.

[0047] The mixed material is discharged through the guide plate 20. The valve on the top surface of the forming chamber 32 is opened to allow the material to enter the forming chamber 32 and be collected between the two granulating rollers 33 through the collecting trough 34. At the same time, the control motor 31 on the top surface of the support 38 drives the rotating shaft 37 to rotate. The rotating shaft 37 drives the granulating rollers 33 on the outer surface to rotate. Meanwhile, the two gears 35 on the other side mesh with each other, causing the two granulating rollers 33 to rotate relative to each other, thereby forming the water-dispersible granules.

[0048] Next, open the valve on the bottom of the forming chamber 32 to allow the water-dispersible granules to enter the screening chamber 41 through the conveying port 42 and fall onto the top surface of the inclined screen 43. Then, start the external drying equipment to allow hot air to enter the drying chamber 47 through the air inlet pipe 46. The hot air will then be discharged through multiple air outlets 45 to dry the water-dispersible granules on the top surface of the screen 43. At the same time, due to the airflow blowing the water-dispersible granules, they will jump, causing qualified products to be discharged through the discharge port 44, while defective products will be screened and fall to the lower part of the screening chamber 41. Use the handle 49 to open the cleaning plate 48 to collect them uniformly.

[0049] Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
