Description

Technical Field

[0001] This utility model relates to the field of herbicide production technology, and more specifically, to a fluidized bed granulation device for water-dispersible herbicide granules. Background Technology

[0002] Water-dispersible granules of herbicides are a type of pesticide formulation. They are made from wettable powders or suspensions through regranulation technology into granular composite reagents. They can quickly disintegrate into a suspension after being added to water. The active ingredient content is usually above 50%. They are suitable for high-value-added pesticides. The active ingredient, wetting agent, dispersant and other ingredients need to be mixed, crushed and processed, and then granulated and dried in a fluidized bed.

[0003] Based on the above, the inventors have discovered that in the existing fluidized bed granulation process, solid-gas separation is performed through a filter bag, and then the filter bag is driven to vibrate up and down by a drive component to shake off the filtered dust. However, the long-term compression and stretching of the filter bag can easily cause damage and seriously affect its service life. Therefore, in view of this, the inventors have studied and improved the existing structure to provide a fluidized bed granulation device for herbicides water-dispersible granules, in order to achieve a more practical purpose. Utility Model Content

[0004] 1. Technical problems to be solved

[0005] To address the problems existing in the prior art, the purpose of this utility model is to provide a fluidized bed granulation device for herbicides water-dispersible granules. This solution is equipped with a reciprocating adjustment component, which can continuously vibrate the filter element, ensuring the dust removal effect while reducing damage to the filter element and extending the service life of the device. In addition, a side vibration component is provided, which can automatically vibrate the side of the filter element during the reciprocating adjustment process, ensuring the vibration is comprehensive and improving the dust removal effect.

[0006] 2. Technical Solution

[0007] To solve the above problems, the present invention adopts the following technical solution.

[0008] A fluidized bed granulation device for water-dispersible herbicides includes a cavity. A feed pipe and an air inlet pipe are fixedly connected to one side of the lower end of the cavity, and an atomizing pipe and a discharge pipe are fixedly connected to the other side of the lower end of the cavity. A drive motor and an air outlet pipe are fixedly connected to the top of the cavity. A pair of support plates are fixedly connected to the center of the upper interior of the cavity, and fixed plates are fixedly connected to both sides of the upper interior of the cavity. A set of filter bags is fixedly connected to the center of the opposite surfaces of the two support plates.

[0009] The output end of the drive motor is fixedly connected to a semi-toothed ring, and a toothed sleeve is fitted on the outer side of the semi-toothed ring. A collision frame is fixedly connected to one side of the toothed sleeve, and a set of side vibration mechanisms is provided on both sides of the collision frame.

[0010] Furthermore, the side vibration mechanism includes a support block, one end of which is fixedly connected to a pressure head, and both sides of the support block are fixedly connected to sliders, with a return spring fixedly connected to one side of each slider.

[0011] Furthermore, an inclined filter plate is fixedly connected to the lower part of the cavity, and the two ends of the filter plate are fixedly connected to the feed pipe and the discharge pipe, respectively.

[0012] Furthermore, a set of tooth blocks is fixedly connected to one side of the semi-tooth ring and the inside of the tooth sleeve on both sides, and the semi-tooth ring and the tooth sleeve are engaged in a meshing connection.

[0013] Furthermore, a pair of sliding rods are fixedly connected to both ends of the collision frame on the outer side. The sliding rods slide against the upper part of the cavity, and the collision frame is adapted to the upper support plate of the two support plates.

[0014] Furthermore, the support block is slidably connected to the collision frame, and one end of the support block on the inner side is adapted to the upper support plate of the two support plates.

[0015] Furthermore, both sides of the extrusion groove and both sides of the pressure head are inclined, and the pressure head is adapted to the extrusion groove.

[0016] 3. Beneficial effects

[0017] Compared with existing technologies, the advantages of this utility model are:

[0018] (1) This solution uses the continuous rotation of the semi-toothed ring and the alternating meshing connection between the semi-toothed ring and the two sides of the toothed sleeve to realize the reciprocating movement of the collision frame. During the reciprocating sliding process of the collision frame, it collides with the upper support plate, causing the filter bag to shake and causing the dust filtered inside the filter bag to fall off. Compared with the existing technology, the reciprocating adjustment component can continuously vibrate the filter element, which not only ensures the dust removal effect, but also reduces the damage to the filter element and extends the service life of the device.

[0019] (2) By setting a side vibration mechanism, when the pressure head at one end of the support block separates from the extrusion groove, it is squeezed by the inclined surface of the extrusion groove, causing the support block to slide inward and collide with the side of the support plate. When the support block separates from the end face of the fixed plate, under the action of the return spring, the slider drives the support block to return to the inside of the extrusion groove. Then the support block and the inner end of the support plate will cycle and continuously impact the side of the support plate. Compared with the prior art, setting a side vibration component can automatically vibrate the side of the filter element during the reciprocating adjustment process, ensuring the comprehensiveness of vibration and improving the dust removal effect.

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0027] Example:

[0028] Please see Figure 1-5 A fluidized bed granulation device for herbicide water-dispersible granules includes a cavity 1. A feed pipe 2 and an air inlet pipe 3 are fixedly connected to one side of the lower end of the cavity 1, and an atomizing pipe 4 and a discharge pipe 5 are fixedly connected to the other side of the lower end of the cavity 1. A drive motor 6 and an air outlet pipe 7 are fixedly connected to the top of the cavity 1. A pair of support plates 18 are fixedly connected to the upper center of the cavity 1, and fixed plates 19 are fixedly connected to both sides of the upper center of the cavity 1. A set of filter bags 8 are fixedly connected to the opposite surfaces of the two support plates 18.

[0029] A semi-toothed ring 10 is fixedly connected to the output end of the drive motor 6. A toothed sleeve 11 is sleeved on the outer side of the semi-toothed ring 10. A collision frame 12 is fixedly connected to one side of the toothed sleeve 11. A set of side vibration mechanisms 13 is provided on both sides of the collision frame 12. When the drive motor 6 is started, the semi-toothed ring 10 is driven to rotate. When the tooth block on one side of the semi-toothed ring 10 meshes with the tooth block on one side of the toothed sleeve 11, the toothed sleeve 11 drives the collision frame 12 to slide to one side.

[0030] See Figure 5 The side vibration mechanism 13 includes a support block 14, one end of which is fixedly connected to a pressure head 15, and both sides of the support block 14 are fixedly connected to sliders 16. One side of the sliders 16 is fixedly connected to a return spring 17. In order to improve the overall vibration and the dust removal effect, the side vibration mechanism 13 is provided.

[0031] See Figure 2 An inclined filter plate is fixedly connected to the lower part of the cavity 1. The two ends of the filter plate are fixedly connected to the feed pipe 2 and the discharge pipe 5, respectively. The raw material is fed into the cavity 1 through the feed pipe 2, and hot air is introduced through the air inlet pipe 3 to make the raw material flow inside the cavity 1. At the same time, the filter bag 8 performs solid-gas separation. The exhaust gas is discharged from the air outlet pipe 7, while the floating dust is filtered inside the filter bag 8. The filter plate plays a limiting role to prevent the raw material from settling to the bottom and ensure the subsequent fluidization effect. Then, the atomizing pipe 4 is activated to spray the binder. Finally, the herbicide water-dispersible granules are formed and discharged from the discharge pipe 5 to complete the granulation work.

[0032] See Figure 4 A set of toothed blocks is fixedly connected to one side of the semi-toothed ring 10 and the inside of the toothed sleeve 11 on both sides. The semi-toothed ring 10 is engaged with the toothed sleeve 11. As the semi-toothed ring 10 continues to rotate, the toothed block on one side of the semi-toothed ring 10 separates from the toothed block on one side of the toothed sleeve 11. At the same time, when it is engaged with the toothed block on the other side of the toothed sleeve 11, the toothed sleeve 11 drives the collision frame 12 to slide to the other side, thereby realizing the reciprocating movement of the collision frame 12.

[0033] See Figure 2 A pair of sliding rods are fixedly connected to both ends of the collision frame 12 on the outer side. The sliding rods slide against the upper part of the cavity 1. The collision frame 12 is adapted to the upper support plate 18 of the two support plates 18. During the reciprocating sliding process of the collision frame 12, it collides with the upper support plate 18, causing the filter bag 8 to shake and causing the dust filtered inside the filter bag 8 to fall off.

[0034] See Figure 4 The support block 14 is slidably connected to the collision frame 12, and one end of the support block 14 on the inner side is adapted to the upper support plate 18 of the two support plates 18. When the collision frame 12 moves, it drives the support block 14 to move.

[0035] See Figure 5Both sides of the extrusion groove 9 and both sides of the pressure head 15 are inclined, and the pressure head 15 is adapted to the extrusion groove 9. When the pressure head 15 at one end of the support block 14 separates from the extrusion groove 9, it is squeezed by the inclined surface of the extrusion groove 9, causing the support block 14 to slide inward as a whole. The inner end of the support block 14 collides with the side of the upper support plate 18. When the support block 14 separates from the end face of the fixed plate 19, under the action of the return spring 17, the slider 16 drives the support block 14 to return to the interior of the extrusion groove 9. Then the support block 14 and the inner end of the support plate 18 repeatedly impact the side of the support plate 18.

[0036] In use: Raw materials are fed into the cavity 1 through the feed pipe 2, while hot air is introduced through the air inlet pipe 3, causing the raw materials to flow inside the cavity 1. Simultaneously, the filter bag 8 performs solid-gas separation, and the exhaust gas is discharged from the air outlet pipe 7. Floating dust is filtered inside the filter bag 8, where the filter plate acts as a limit to prevent the raw materials from settling to the bottom, ensuring subsequent fluidization. Then, the atomizing pipe 4 is activated to spray the binder. Finally, the herbicide water-dispersible granules are formed and discharged from the discharge pipe 5, completing the granulation process. During this process, the drive motor 6 is activated, driving the semi-toothed ring 10 to rotate. When one side of the semi-toothed ring 10 meshes with the other side of the toothed sleeve 11, the toothed sleeve 11 causes the collision frame 12 to slide to one side. As the semi-toothed ring 10 continues to rotate, the toothed block on one side of the semi-toothed ring 10 separates from the toothed block on one side of the toothed sleeve 11, and simultaneously meshes with the toothed block on the other side of the toothed sleeve 11. The toothed sleeve 11 then... The moving collision frame 12 slides to the other side, thereby realizing the reciprocating movement of the collision frame 12. During the reciprocating sliding process, the collision frame 12 collides with the upper support plate 18, causing the filter bag 8 to shake and causing the dust filtered inside the filter bag 8 to fall off. When the collision frame 12 moves, it drives the support block 14 to move. When the pressure head 15 at one end of the support block 14 separates from the extrusion groove 9, it is squeezed by the inclined surface of the extrusion groove 9, causing the support block 14 to slide inward as a whole. The inner end of the support block 14 collides with the side of the upper support plate 18. When the support block 14 separates from the end face of the fixed plate 19, under the action of the return spring 17, the slider 16 drives the support block 14 to return to the extrusion groove 9. Then the support block 14 and the inner end of the support plate 18 repeatedly impact the side of the support plate 18, improving the overall vibration and improving the dust removal effect.
