Description

Technical Field

[0001] The present application relates to the technical field of granulation devices, and particularly relates to a slurry spray rotary granulation device. Background Art

[0002] Slurry spray rotary granulation is a process for producing chemical fertilizers, especially suitable for the production of compound fertilizers. During slurry spray rotary granulation, a mixture of fertilizer and binder is first atomized by a slurry sprayer to form fine particles. These particles then rotate inside a drum granulator, and the centrifugal force generated by the rotation causes the particles to collide and bond with each other, finally forming particles of a certain size and shape. During the particle forming process, it can ensure the uniform distribution of nutrients in the fertilizer, improve the quality and effect of the fertilizer, and also improve the granulation efficiency and reduce the production cost.

[0003] Referring to the Chinese patent document with the reference publication number CN208694933U and the name of a slurry spray granulation device for organic fertilizer production, it includes a feed inlet, a diversion pipe, a granulation device, and a connecting pipe. The granulation device includes a housing and a spiral return tank. When in use, first, the fertilizer enters the interior of the granulation device from the feed inlet, the slurry is atomized and sprayed, the diversion pipe guides it into the granulation device, and the temperature inside the particles is controlled uniformly through a temperature control system. Then, by starting the power motor, the spiral return tank rotates, and the fertilizer gradually forms inside the spiral return tank and finally flows out from the connecting pipe. The production efficiency of the fertilizer is high and the particles are uniform.

[0004] Referring to the above technical solution, when the slurry is sprayed inside the rotating tank, the surface of the originally dry fertilizer becomes wet and gradually forms under the action of the rotating tank. However, during the fertilizer forming process, the wet fertilizer on the surface is likely to adhere to the inner wall of the rotating tank in a certain temperature environment. As time goes by, the adhered material is likely to show a caking phenomenon, and the lumps are not easy to fall off. During the granulation production process of the fertilizer, the particles are not easy to directly contact the inner wall of the rotating tank, which is likely to affect the production quality of the particles and the working efficiency of the equipment is likely to decline. Summary of the Invention

[0005] In view of this, the present application provides a slurry spray rotary granulation device, which is mainly used to solve the problem that raw materials are easily caked and adhered to the inner wall of the rotating tank.

[0006] To solve the above technical problems, the present application provides a spraying rotary granulation device, including a base, a rotating tank, a temperature control component, and a spraying component. The rotating tank is arranged in a cylindrical shape. The spraying component includes a spraying pipeline installed on the base, and the spraying pipeline is coaxially arranged with the rotating tank. A shunt pipe is connected to the outer surface of the spraying pipeline. A plurality of shunt pipes are provided, and the interior of the shunt pipe is arranged in a hollow structure. A stirring tooth part for granulating the raw materials is coaxially arranged on the shunt pipe. The stirring tooth part includes a stirring tooth rod, which is vertically installed. A crushing rod is sleeved on the stirring tooth rod, and a crushing hammer for breaking the lumps on the inner wall of the rotating tank is installed at the end of the crushing rod.

[0007] By adopting the above technical solution, the rotating tank is driven by an external driving source to rotate around its own axis. The temperature control component can control the temperature inside the rotating tank and adjust the temperature inside the rotating tank in real time during the formation of the fertilizer, assisting in the formation of fertilizer particles. The spraying component can spray the slurry into the interior of the rotating tank, making the dry fertilizer moist and condensing into granular form. A plurality of shunt pipes are provided, which can make the slurry flow out from multiple shunt pipes, helping to disperse the materials during spraying, enabling the raw materials to be more evenly distributed inside the rotating tank, being conducive to the formation of uniform particles. The stirring tooth part granulates and shapes the humidified raw materials, helping the raw materials to better form particles and also preventing particle adhesion. Under the hydraulic action of the slurry, the crushing rod can extend and slide outwards, enabling the crushing hammer to contact the inner wall of the rotating tank. The crushing rod and the crushing hammer can effectively break and crush the lumps that may form on the inner wall of the rotating tank, ensuring the continuity and stability of the granulation process.

[0008] The design of components such as the spraying pipeline, shunt pipe, and stirring tooth part is relatively modular, which is conducive to daily maintenance and cleaning work. Uniform granulation and effective lump treatment help to improve the quality of the final product and meet higher-end market demands.

[0009] Optionally, a spraying orifice is transversely opened on the stirring tooth rod.

[0010] By adopting the above technical solution, the spraying orifice is transversely arranged on the stirring tooth rod, which can evenly spray the raw materials in the circumferential direction during rotation, helping to form uniform particles and improve product quality. When the stirring tooth rod stirs the materials, the slurry can be evenly sprayed onto the surface of the materials through the spraying orifice, thus achieving a uniform mixing and coating effect. The position and direction of the spraying orifice can precisely control the spraying of the slurry, reducing unnecessary slurry loss and improving material utilization rate.

[0011] Optionally, an arc-shaped clamping block is opened on the crushing rod, and a first clamping groove and a second clamping groove are transversely opened on the inner wall of the stirring tooth rod. The first clamping groove is located above the second clamping groove.

[0012] By adopting the above technical solution, when the stirring tooth rod and the crushing rod are pushed to extend outwards under the action of the slurry pressure, the arc-shaped clamping block can be clamped on the second clamping groove, temporarily limiting the crushing rod, so that the crushing hammer contacts the inner wall of the rotating tank. When the arc-shaped clamping block is clamped on the first clamping groove, the liquid can flow out from the bottom of the stirring tooth rod and out of the slurry spraying port.

[0013] The cooperation of the arc-shaped clamping block with the first and second clamping grooves can ensure the stable fixation of the crushing rod on the stirring tooth rod, preventing the crushing rod from shifting during high-speed rotation or vibration. The crushing rod is fixed by the clamping block and the clamping groove, reducing the risk of the crushing hammer falling off, improving the safety of the equipment operation. The stable operation of the crushing hammer helps to break the lumps on the inner wall in time, maintain the uniformity of the granulation process, avoid uneven particle sizes caused by lumps, and improve the production efficiency.

[0014] Optionally, a connecting plate for preventing the crushing rod from slipping out of the stirring tooth rod is installed on the crushing rod.

[0015] By adopting the above technical solution, the existence of the connecting plate can effectively prevent the crushing rod from slipping out of the stirring tooth rod during high-speed rotation or vibration, ensuring the safety of the equipment during operation; the connecting plate fixes the crushing rod, reducing the movement of the crushing rod in the stirring tooth rod, improving the stability of the entire stirring tooth system, and thus ensuring the continuity and uniformity of the granulation process.

[0016] Optionally, a return spring is arranged around the crushing rod, and both ends of the return spring are respectively installed on the inner wall of the shunt pipe and the connecting plate.

[0017] By adopting the above technical solution, the return spring can drive the crushing rod to reset, making the arc-shaped clamping block clamped in the first clamping groove. The return spring can automatically pull the crushing hammer back to its original position after hitting the lumps, ensuring that the crushing hammer always stays in the working position, improving the working efficiency. The automatic reset function of the return spring reduces the continuous contact between the crushing hammer and the inner wall of the rotating tank, thereby reducing wear and extending the service life of the equipment. The return spring enables the crushing hammer to have a certain range of movement to better adapt to the irregular shape of the inner wall of the rotating tank and the position of the lumps. The automatic reset of the return spring reduces the additional energy consumption because no external power is required to reset the crushing hammer. Overall, the design of the return spring improves the performance of the slurry spraying rotary granulation device, making it more efficient, reliable and durable.

[0018] Optionally, a support plate is installed on the base, and a second motor for driving the slurry spraying pipeline to rotate is installed on the support plate.

[0019] By adopting the above technical solution, the output shaft of the second motor can drive the slurry spraying pipeline to rotate, and then drive the shunt pipe to rotate.

[0020] Optionally, a feed bin is connected to the rotating tank.

[0021] By adopting the above technical solution, the opening of the feed bin extends upward and outward, which can prevent spilling when filling raw materials. The setting of the feed bin can achieve continuous automatic feeding, reduce manual intervention, and improve production efficiency. The feed bin can ensure that the raw materials are conveyed to the rotary tank at a stable rate, which helps to maintain the stability of the granulation process. Since the feed bin can store a certain amount of raw materials, continuous production can be carried out without frequent feeding, reducing the downtime. The design of the feed bin can reduce the chance of workers directly contacting the raw materials and lower the safety risks in the workplace. The feed bin is usually located above or on the side of the rotary tank, which can effectively utilize the space and save the floor area.

[0022] Optionally, a C-shaped plate for preventing the slurry from flowing out of the shunt pipe is sleeved and installed inside the slurry spraying pipe. A rotary handwheel is installed through the outer wall of the feed bin where the C-shaped plate penetrates.

[0023] By adopting the above technical solution, when the opening of the shunt pipe corresponds to the C-shaped plate, the liquid slurry can enter the shunt pipe, and the hydraulic pressure drives the crushing rod to approach the inner wall of the rotary tank. The crushing head can break the agglomerated blocks on the inner wall of the rotary tank. The rotary handwheel can control the rotation of the C-shaped plate to change the position of spraying or not spraying. By adjusting the position of the C-shaped plate through the rotary handwheel, the flow rate of the slurry flowing into the shunt pipe can be precisely controlled, thereby optimizing the granulation process. By precisely controlling the slurry flow rate, it helps to maintain the uniformity of the granulation process and improve the product quality. The C-shaped plate and the rotary handwheel have significant beneficial effects in improving the operation convenience, safety, stability and material utilization rate of the slurry spraying equipment. At the same time, it also helps to reduce the maintenance cost and improve the production efficiency.

[0024] Optionally, a first motor is installed on the base. A driving gear is installed on the output shaft of the first motor. A driven gear meshing with the driving gear is arranged around the outer wall of the rotary tank.

[0025] By adopting the above technical solution, the output shaft of the first motor can drive the driving gear to rotate, and the driven gear meshing with the driving gear rotates, which can make the rotary tank rotate.

[0026] Optionally, an auxiliary rotating ring is fixedly arranged on the outer wall of the rotary tank. An auxiliary rotating wheel abutted against the auxiliary rotating ring is installed on the base.

[0027] By adopting the above technical solution, while the rotary tank rotates, the auxiliary rotating ring rotates synchronously, and the auxiliary rotating wheel abutting against the auxiliary rotating ring rotates, which can assist the rotation of the rotary tank and improve the efficiency of the raw materials in the rotary tank being granulated. The setting of the auxiliary rotating ring and the auxiliary rotating wheel can increase the stability of the rotary tank and reduce the swing or deviation that may occur during the rotation process, thereby improving the stability of the granulation process. The design of the auxiliary rotating wheel and the rotating ring can enhance the carrying capacity of the equipment, so that the rotary tank can withstand a larger load and is suitable for large-scale production.

[0028] In summary, compared with the prior art, the present application includes at least one of the following beneficial technical effects:

[0029] 1. By cleverly utilizing the hydraulic pressure of the slurry, the breaker rod can be extended outward, so that the breaker hammer can contact the inner wall of the rotating tank. The materials that are bonded and compacted on the inner wall of the rotating tank are crushed, which can ensure the smoothness of the tank body and avoid reducing the production efficiency of particle forming due to the compaction of materials.

[0030] 2. Through the design of the reset spring, the connection plate can cancel the contact with the inner wall of the stirring gear rod, ensuring that the slurry flows out from the spraying port and is evenly sprayed on the bonded and compacted raw materials or the raw materials inside the mixing tank. The C-type plate can prevent the inside of the rotating tank from being in a spraying state all the time. Only when the opening of the C-type plate coincides with the liquid outlet of the diversion pipe can the spraying be carried out to prevent the raw materials from being too wet. By manually turning the rotating hand wheel, the position of the C-type plate can be changed, thereby changing the position of the spraying, preventing the raw materials from being bonded or compacted on the inner wall of the rotating tank from being difficult to remove.

[0031] 3. The hydraulic principle enables the breaker rod and breaker hammer to automatically clean the sticky and compacted raw materials, which can reduce the frequency and difficulty of manual cleaning, thereby reducing maintenance costs. By effectively cleaning the compacted fertilizer, the utilization rate of materials can be improved and the waste of raw materials can be reduced.

[0032] 4. When the rotating tank is rotating, the auxiliary rotation of the auxiliary swivel and the auxiliary wheel can enhance the carrying capacity of the equipment, so that the rotating tank can withstand a larger load, and at the same time reduce the output of the driving source of the rotating tank.

Figures 1-8 , clearly and completely describe the technical solutions of the embodiments of the present application.

[0043] Reference Figure 1 , Figure 2 , Figure 3 and Figure 7 The present embodiment provides a spraying rotary granulation device, including a base 1, a rotating tank 2, a temperature control component, a spraying component 3, a stirring tooth 4, a crushing component 5, and a spraying position adjustment component 6. The rotating tank 2 is rotatably mounted on the base 1, and the rotating tank 2 is configured to be cylindrical. The temperature control component is used to adjust the temperature in the rotating tank 2. The spraying component 3 is arranged on the base 1 and located inside the rotating tank 2, and is used to spray slurry to the raw materials inside the rotating tank 2. The stirring tooth 4 is used to granulate the raw materials. The crushing component 5 is used to crush the raw materials that are bonded and compacted on the inner wall of the rotating tank 2.

[0044] Reference Figure 1, a feed bin 21 is installed on the rotating tank 2. The feed bin 21 is connected to one end of the rotating tank 2, and the interior of the feed bin 21 is in communication with the interior of the rotating tank 2.

[0045] Referring to Figure 1 , Figure 2 and Figure 3 , the slurry spraying assembly 3 includes a support plate 34, a second motor 35, a slurry spraying pipe 31 and a shunt pipe 32. The base 1 is horizontally arranged transversely. The support plate 34 is installed on the base 1. The support plate 34 is set as a U-shaped support plate and is installed vertically upside down on the base 1. The second motor 35 is arranged on the flat plate at the top of the U-shaped support plate. One end of the slurry spraying pipe 31 is connected to the output shaft of the second motor 35, and the other end is sleeved and installed on the feed bin 21. A feed pipe is coaxially sleeved on the slurry spraying pipe 31, and an L-shaped support plate for supporting the feed pipe is installed on the feed bin 21.

[0046] The shunt pipe 32 is connected to the outer surface of the slurry spraying pipe 31. The interior of the shunt pipe 32 is in communication with the slurry spraying pipe 31. The shunt pipe 32 is set in three groups, and each group is composed of a plurality of shunt pipes 32. Each group of shunt pipes 32 is arranged in a spiral curve around the slurry spraying pipe 31.

[0047] Referring to Figure 2 and Figure 3 , the stirring tooth member 4 includes a stirring tooth rod 41, and the slurry spraying assembly 3 further includes a slurry spraying port 33. The interior of the stirring tooth rod 41 is set as a hollow structure. The stirring tooth rod 41 is sleeved and installed on the shunt pipe 32, and the slurry spraying port 33 is horizontally opened on the stirring tooth rod 41.

[0048] During use, first, slurry is introduced into the feed pipe. The slurry flows into the slurry spraying pipe 31, the shunt pipe 32 and the stirring tooth rod 41 in sequence, and is sprayed out from the slurry spraying port 33. When the second motor 35 is started, it can drive the slurry spraying pipe 31 to rotate, thereby driving the shunt pipe 32 to rotate. The slurry sprayed out from the slurry spraying port 33 can be evenly sprayed on the raw materials inside the rotating tank 2.

[0049] Referring to Figure 3 and Figure 5, the crushing member 5 includes a crushing rod 51, a crushing hammer 52 and a connecting plate 57. The stirring tooth rod 41, the crushing rod 51 and the crushing rod 51 are coaxially arranged. The interiors of the stirring tooth rod 41 and the crushing rod 51 are both hollow structures. The upper end of the stirring tooth rod 41 is provided with a first cylindrical groove 42 and the lower end is provided with a second cylindrical groove 43. The first cylindrical groove 42 and the second cylindrical groove 43 are communicated and the diameter of the first cylindrical groove 42 is larger than the diameter of the second cylindrical groove 43. The crushing rod 51 is sleeved on the first cylindrical groove 42 and the second cylindrical groove 43 of the stirring tooth rod 41, and the diameter of the crushing rod 51 is slightly smaller than the diameter of the second cylindrical groove 43. The connecting plate 57 is fixedly installed on the crushing rod 51 and is located in the first cylindrical groove 42. The crushing hammer 52 is installed on the crushing rod 51 and is used for crushing the agglomerated or caked raw materials. The crushing rod 51 is telescopic so as to drive the crushing hammer 52 to contact or move away from the inner wall of the rotating tank 2.

[0050] Refer to Figure 2 , Figure 7 and Figure 8 , the crushing member 5 further includes an arc-shaped clamping block 53, a compression spring 54, a first clamping groove 55, a second clamping groove 56, and a return spring 58. A cylindrical hole is provided on the curved side wall of the crushing rod 51. A cylinder is placed inside the cylindrical hole. The end of the cylinder is fixedly installed with the arc-shaped clamping block 53. The arc-shaped clamping block 53 is set as a semi-spherical shape. The plane of the semi-spherical shape is fixedly connected to the plane of the cylinder. A compression spring 54 is arranged around the cylinder. The two ends of the compression spring 54 are respectively fixedly connected to the inner wall of the cylindrical hole and the side wall of the cylinder, which can drive the cylinder and the arc-shaped clamping block 53 to reciprocate inside the cylindrical hole. The first clamping groove 55 and the second clamping groove 56 are both provided on the stirring tooth rod 41, and the first clamping groove 55 is located directly above the second clamping groove 56. The arc-shaped clamping block 53 is clamped in the first clamping groove 55 or the second clamping groove 56. The return spring 58 is arranged around the crushing rod 51. The two ends of the return spring 58 are respectively fixedly connected to the inner wall of the shunt pipe 32 and the connecting plate 57.

[0051] Refer to Figure 2 , Figure 4 and Figure 7 , the spraying position adjusting member 6 includes a C-shaped plate 61 and a rotating handwheel 62. The C-shaped plate 61 is sleeved and installed inside the spraying pipe 31. During the continuous rotation of the spraying pipe 31, the spraying pipe 31 in contact with the outer side wall of the C-shaped plate 61 can prevent the spraying of the slurry. On the contrary, the spraying pipe 31 not in contact with the outer side wall of the C-shaped plate 61 can allow the slurry to be sprayed, which can prevent excessive spraying of the slurry. The end of the C-shaped plate 61 penetrates through the side wall of the feeding bin 21. A rotating handwheel 62 is installed on the feeding bin 21, which can drive the C-shaped plate 61 to rotate and control the specific spraying position.

[0052] During use, first rotate the rotary handwheel 62 to adjust the position of the C-shaped plate 61. The slurry is poured into the inside of the stirring tooth rod 41. When the liquid outlet of the shunt pipe 32 on the slurry pipeline coincides with the opening of the C-shaped plate 61, the slurry can enter the shunt pipe 32. The hydraulic pressure drives the crushing rod 51 to approach the inner wall of the rotary tank 2. The compression spring 54 is compressed under pressure, causing the cylinder body and the arc-shaped clamping block 53 to retract into the cylindrical hole. The arc-shaped clamping block 53 abuts against the inner wall of the first clamping groove 55 in sequence, the inner wall of the stirring tooth rod 41, and finally slides to the second clamping groove 56 and abuts against the inner wall of the second clamping groove 56. At this time, the crushing head extends outward synchronously with the crushing rod 51. The crushing head is misaligned with the slurry spraying port 33, and the slurry sprays out from the slurry spraying port 33. The crushing hammer 52 contacts the inner wall of the rotary tank 2 to break up the bonded and caked raw materials.

[0053] On the contrary, when the outlet of the shunt pipe 32 on the slurry pipeline is aligned with the outer side wall of the C-shaped plate 61, the slurry stops entering the shunt pipe 32, the hydraulic pressure decreases, and under the action of the return spring 58, the elastic force of the return spring 58 retracts, causing the arc-shaped clamping block 53 to move back into the first clamping groove 55. At this time, the outer side wall of the crushing hammer 52 coincides with the slurry spraying port 33 to prevent the slurry from spraying out.

[0054] When it is necessary to adjust the slurry spraying and crushing positions, only need to rotate the rotary handwheel 62 to adjust the C-shaped plate 61 to different positions corresponding to the slurry spraying pipeline 31.

[0055] Refer to Figure 1 As shown in the figure, the rotary tank 2 is driven by the first motor 22, the driving gear 23, the driven gear 24, the auxiliary rotating ring 25 and the auxiliary rotating wheel 26. The first motor 22 is fixedly installed on the base 1. The driving gear 23 is installed on the output shaft of the first motor 22. The driven gear 24 is arranged around the outer wall of the rotary tank 2 and meshes with the driving gear 23. The auxiliary rotating ring 25 is fixedly installed on the outer wall of the rotary tank 2. The wheel bases are symmetrically installed on the front and back of the base 1, and the auxiliary rotating wheel 26 is installed on the wheel base. The auxiliary rotating ring 25 and the auxiliary rotating wheel 26 are provided in two groups, which can better assist the rotation of the rotary tank 2.

[0056] During use, first start the first motor 22. The output shaft of the first motor 22 can drive the driving gear 23 to rotate, and then the driven gear 24 meshing with the driving gear 23 rotates, which can drive the rotary tank 2 to rotate synchronously. The auxiliary rotating ring 25 on the rotary tank 2 rotates synchronously. While the auxiliary rotating wheel 26 supports the auxiliary rotating ring 25, it can assist and accelerate the rotation of the rotary tank 2.

[0057] The implementation principle of a slurry spraying and rotary granulation device in an embodiment of the present application is as follows:

[0058] When using this device, first pour the raw materials from the feed bin 21 into the rotary tank 2, and then start the first motor 22. The output shaft of the first motor 22 drives the driving gear 23 to rotate. Synchronously, the driven gear 24, the rotary tank 2, the auxiliary rotating ring 25, the auxiliary rotating wheel 26 and the rotary tank 2 rotate, and the raw materials inside the rotary tank 2 keep tumbling.

[0059] Then rotate the rotary handwheel 62 to adjust the position where the C-shaped plate 61 contacts the spraying pipeline 31, so as to determine the spraying position. Then start the second motor 35. The output shaft of the second motor 35 drives the spraying pipeline 31 to rotate. When the inner wall of the spraying pipeline 31 separates from the outer wall of the C-shaped plate 61, the spraying pipeline 31 enters the shunt pipe 32. The hydraulic pressure inside the shunt pipe 32 increases, which can drive the crushing rod 51 and the arc-shaped clamping block 53 on the crushing rod 51 to extend outwards. The arc-shaped clamping block 53 slides from the first clamping groove 55 to the second clamping groove 56. Synchronously, the crushing hammer 52 moves outwards relative to the spraying port 33, and the crushing hammer 52 contacts the inner wall of the rotary tank 2 to break the bonded and caked materials on the inner wall of the rotary tank 2; when the inner wall of the spraying pipeline 31 contacts the outer wall of the C-shaped plate 61, the slurry stops entering the shunt pipe 32 from the connection between the shunt pipe 32 and the spraying pipeline 31. At this time, the hydraulic pressure inside the shunt pipe 32 decreases, and the elastic force of the return spring 58 retracts, driving the crushing rod 51 to return to its original position. At this time, the arc-shaped clamping block 53 is clamped in the first clamping groove 55, and the crushing hammer 52 coincides with the spraying port 33, and the spraying port 33 stops spraying the slurry outwards.

[0060] The stirring tooth part 4 can knead the raw materials inside the rotary tank 2 into granular raw materials. After the crushing hammer 52 breaks the bonded and caked raw materials on the inner wall of the rotary tank 2, the stirring tooth part 4 can continue to granulate the falling raw materials, and at the same time prevent the bonded and caked materials from appearing on the inner wall of the rotary tank 2, clean the inner wall in time, ensure the working efficiency, reduce the frequency and difficulty of manual cleaning, thereby reducing the maintenance cost. At the same time, it can improve the utilization rate of the materials and reduce waste.

[0061] In addition, it should be noted that in the description of the present application, unless otherwise clearly specified and limited, the terms "installation", "connection" and "connection" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the communication inside two components.
