Description

Technical Field

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

[0002] Spraying rotary granulation is a process used to produce fertilizers, especially compound fertilizers. In the spraying rotary granulation process, the mixture of fertilizer and binder is first atomized by the sprayer to form fine particles, which are then rotated in the drum granulator. The centrifugal force generated by the rotation causes the particles to collide and bond with each other, eventually forming particles of a certain size and shape. The particle forming process can ensure that the nutrients in the fertilizer are evenly distributed, improve the quality and effect of the fertilizer, and also improve the granulation efficiency and reduce production costs.

[0003] Referring to the Chinese patent document with the announcement number CN208694933U, the name is a spraying granulation device for organic fertilizer production, which includes a feed port, a guide pipe, a granulation device and a connecting pipe, wherein the granulation device includes a shell and a spiral return tank. When in use, the fertilizer is first allowed to enter the granulation device from the feed port, the slurry is atomized for spraying, the guide pipe guides it into the granulation device, and the temperature inside the particles is controlled by the temperature control system. After that, the power motor is started to rotate the spiral return tank, and the fertilizer is gradually formed inside the spiral return tank, and finally flows out from the connecting pipe, and the fertilizer production efficiency 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 moist and gradually takes shape under the action of the rotating tank. However, during the fertilizer forming process, the fertilizer with a moist surface is easy to adhere to the inner wall of the rotating tank under a certain temperature environment. As time goes by, the bonded material is prone to hardening and the lumps are not easy to fall off. During the fertilizer granulation production process, the particles are not easy to directly contact the inner wall of the rotating tank, which can easily affect the production quality of the particles and the working efficiency of the equipment is easy to decrease. Summary of the invention

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

[0006] In order to solve the above technical problems, the present application provides a spraying rotary granulation device, comprising 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 comprises a spraying pipe installed on the base. The spraying pipe is coaxially arranged with the rotating tank. A shunt pipe is connected to the outer surface of the spraying pipe. There are multiple shunt pipes. The interior of the shunt pipe is arranged as a hollow structure. A stirring tooth piece for granulating the raw material is coaxially arranged on the shunt pipe. The stirring tooth piece comprises a stirring tooth rod. The stirring tooth rod is vertically installed. A breaking rod is sleeved on the stirring tooth rod. A breaking hammer for scratching the lumps on the inner wall of the rotating tank is installed at the end of the breaking rod.

[0007] By adopting the above technical scheme, 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 fertilizer formation process to assist the formation of fertilizer particles. The spraying component can spray slurry into the interior of the rotating tank to make the dry fertilizer moist and condense into particles. There are multiple shunt pipes, so that the slurry can flow out from multiple shunt pipes, which is helpful for the dispersion of materials during spraying, so that the raw materials can be more evenly distributed in the rotating tank, which is conducive to the formation of uniform particles. The agitator rubs the humidified raw materials into particles, which helps the raw materials to form particles better and prevents the particles from sticking. Under the hydraulic action of the slurry, the breaking rod can extend and slide outward, so that the breaking hammer can contact the inner wall of the rotating tank. The breaking rod and the breaking hammer can effectively scratch and break the lumps that may be formed on the inner wall of the rotating tank, thereby ensuring the continuity and stability of the granulation process.

[0008] The design of components such as spraying pipes, diverter pipes, and agitator teeth is relatively modular, which is conducive to daily maintenance and cleaning. Uniform granulation and effective agglomeration treatment help to improve the quality of the final product and meet higher-end market demands.

[0009] Optionally, a spraying port is horizontally opened on the stirring gear rod.

[0010] By adopting the above technical solution, the spray port is horizontally arranged on the stirring gear rod, and the raw materials can be evenly sprayed in the circumferential direction during the rotation process, which is helpful to form uniform particles and improve product quality. When the stirring gear rod is stirring in the material, the slurry can be evenly sprayed onto the surface of the material through the spray port, thereby achieving a uniform mixing and coating effect. The position and direction of the spray port can accurately control the injection of the slurry, reduce unnecessary slurry loss and improve material utilization.

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

[0012] By adopting the above technical solution, under the action of the slurry pressure, when the agitator gear rod and the breaker rod are pushed to extend outward, the arc-shaped clamping block can be clamped on the second clamping groove, which can temporarily limit the breaker rod and make the breaker hammer contact with 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 agitator gear rod and out of the spray port.

[0013] The cooperation between the arc-shaped clamping block and the first clamping groove and the second clamping groove can ensure that the breaker bar is stably fixed on the agitator tooth bar to prevent the breaker bar from being displaced during high-speed rotation or vibration. The breaker bar is fixed by the clamping block and the clamping groove, which reduces the risk of the breaker hammer falling off and improves the safety of equipment operation. The stable operation of the breaker hammer helps to break the agglomerates on the inner wall in time, maintain the uniformity of the granulation process, avoid uneven particle sizes due to agglomeration, and improve production efficiency.

[0014] Optionally, a connecting plate is installed on the breaker bar to prevent the breaker bar from slipping out of the stirring gear bar.

[0015] By adopting the above technical solution, the presence of the connecting plate can effectively prevent the crushing rod from slipping out of the agitator gear rod during high-speed rotation or vibration, thereby ensuring the safety of the equipment during operation; the connecting plate fixes the crushing rod, reduces the movement of the crushing rod in the agitator gear rod, and improves the stability of the entire agitator gear system, thereby ensuring the continuity and uniformity of the granulation process.

[0016] Optionally, a return spring is disposed around the breaker rod, and two ends of the return spring are respectively mounted on the inner wall of the shunt pipe and the connecting plate.

[0017] By adopting the above technical scheme, the reset spring can drive the breaker rod to reset, so that the arc-shaped block is stuck in the first slot. The reset spring can automatically pull the breaker back to its original position after the breaker hammer hits the agglomerate, ensuring that the breaker hammer always remains in the working position and improves work efficiency. The automatic reset function of the reset spring reduces the continuous contact between the breaker hammer and the inner wall of the rotating tank, thereby reducing wear and extending the service life of the equipment. The reset spring enables the breaker hammer to have a certain range of motion to better adapt to the irregular shape of the inner wall of the rotating tank and the position of the agglomerate. The automatic reset of the reset spring reduces additional energy consumption because no external power is required to reset the breaker hammer. On the whole, the design of the reset spring improves the performance of the 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 spraying pipe 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 shotcrete pipe to rotate, thereby driving the diversion pipe to rotate.

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

[0021] By adopting the above technical solution, the opening of the feed bin extends upward and outward, which can prevent spillage when filling in raw materials. The setting of the feed bin can realize continuous automatic feeding, reduce manual intervention, and improve production efficiency. The feed bin can ensure that the raw materials are transported to the rotating 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 achieved without frequent feeding, reducing downtime. The design of the feed bin can reduce the opportunity for workers to directly contact the raw materials and reduce safety risks in the workplace. The feed bin is usually located above or on the side of the rotating tank, which can effectively utilize space and save floor space.

[0022] Optionally, a C-type plate is installed inside the shotcrete pipe to prevent the slurry from flowing out of the diversion pipe, and a rotating handwheel is installed on the outer wall of the C-type plate that passes through the feed bin.

[0023] By adopting the above technical solution, when the shunt pipe corresponds to the opening of the C-type plate, the slurry can enter the shunt pipe, the hydraulic pressure drives the crushing rod to approach the inner wall of the rotating tank, and the crushing head can crush the plate lumps on the inner wall of the rotating tank. The rotating handwheel can control the rotation of the C-type plate to change the position of spraying or not spraying. By rotating the handwheel to adjust the position of the C-type plate, the flow rate of the slurry to the shunt pipe can be accurately controlled, thereby optimizing the granulation process. By accurately controlling the slurry flow rate, it helps to maintain the uniformity of the granulation process and improve product quality. The C-type plate and the rotating handwheel can have significant beneficial effects in improving the convenience of operation, safety, stability and material utilization of the spraying equipment, and also help to reduce maintenance costs and improve 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, and a driven gear meshing with the driving gear is arranged around the outer wall of the rotating 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, so that the rotating tank can rotate.

[0026] Optionally, an auxiliary rotating ring is fixedly provided on the outer wall of the rotating tank, and an auxiliary rotating wheel abutting 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: 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.

[0029] 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.

[0030] 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.

[0031] 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.

[0039] Reference Figure 2 and Figure 3 The agitating gear member 4 includes an agitating gear rod 41, and the spraying assembly 3 also includes a spraying port 33. The interior of the agitating gear rod 41 is set as a hollow structure, the agitating gear rod 41 is sleeved and installed on the diversion pipe 32, and the spraying port 33 is horizontally opened on the agitating gear rod 41.

[0040] When in use, firstly, the liquid slurry is introduced into the feed pipe, and the liquid slurry flows into the spraying pipe 31, the diverter pipe 32 and the agitator gear rod 41 in sequence, and is sprayed out from the spraying port 33. When the second motor 35 is started, the spraying pipe 31 can be driven to rotate, and then the diverter pipe 32 can be rotated, and the slurry sprayed from the spraying port 33 can be evenly sprayed on the raw materials inside the rotating tank 2.

[0041] Reference Figure 3 and Figure 5 The crushing member 5 includes a crushing rod 51, a crushing hammer 52 and a connecting plate 57. The agitating tooth rod 41, the crushing rod 51 and the crushing rod 51 are coaxially arranged, and the interiors of the agitating tooth rod 41 and the crushing rod 51 are both arranged as hollow structures. The upper end of the agitating 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 connected 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 on the agitating 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 mounted on the crushing rod 51 and is located in the first cylindrical groove 42. The crushing hammer 52 is mounted on the crushing rod 51 to crush the bonded or hardened raw materials. The crushing rod 51 can be extended and retracted to drive the crushing hammer 52 to contact or move away from the inner wall of the rotating tank 2.

[0042] Reference Figure 2 , Figure 7 and Figure 8The crushing member 5 further includes an arc block 53, a compression spring 54, a first slot 55, a second slot 56, and a reset 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, an arc block 53 is fixedly installed at the end of the cylinder, the arc block 53 is set to be semi-spherical, 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, and 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 block 53 to slide back and forth inside the cylindrical hole, the first slot 55 and the second slot 56 are both provided on the stirring gear rod 41, and the first slot 55 is located directly above the second slot 56, the arc block 53 is clamped on the first slot 55 or the second slot 56, the reset spring 58 is arranged around the crushing rod 51, and the two ends of the reset spring 58 are respectively fixedly connected to the inner wall of the shunt pipe 32 and the connecting plate 57.

[0043] Reference Figure 2 , Figure 4 and Figure 7 The spraying position adjustment member 6 includes a C-shaped plate 61 and a rotating hand wheel 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 wall of the C-shaped plate 61 can prevent the slurry from being sprayed out. On the contrary, the spraying pipe 31 not in contact with the outer wall of the C-shaped plate 61 can make the slurry spray out, which can prevent the slurry from being sprayed too much. The end of the C-shaped plate 61 passes through the side wall of the feed bin 21. The feed bin 21 is equipped with a rotating hand wheel 62, which can drive the C-shaped plate 61 to rotate and control the specific position of the spraying.

[0044] When in use, first turn the rotating hand wheel 62 to adjust the position of the C-plate 61, and the slurry is poured into the interior of the stirring gear rod 41. When the liquid outlet of the shunt pipe 32 on the slurry pipeline coincides with the opening of the C-plate 61, the slurry can enter the shunt pipe 32, and the hydraulic pressure drives the crushing rod 51 to approach the inner wall of the rotating tank 2. The compression spring 54 is compressed by the pressure, so that the column and the arc-shaped block 53 retract into the cylindrical hole. The arc-shaped block 53 abuts against the inner wall of the first groove 55 and the inner wall of the stirring gear rod 41 in turn, and finally slides to the second groove 56 and abuts against the inner wall of the second groove 56. At this time, the crushing head extends outward synchronously with the crushing rod 51, and the crushing head is misaligned with the spraying port 33. The slurry is sprayed out from the spraying port 33, and the breaker 52 contacts the inner wall of the rotating tank 2 to crush the bonded and compacted raw materials.

[0045] On the contrary, when the outlet of the diverter pipe 32 on the slurry pipeline is aligned with the outer wall of the C-shaped plate 61, the slurry stops entering the diverter pipe 32, the hydraulic pressure decreases, and under the action of the return spring 58, the elastic force of the return spring 58 shrinks, causing the arc-shaped block 53 to move back to the first groove 55. At this time, the outer wall of the breaker 52 coincides with the spraying outlet 33 to prevent the slurry from spraying out.

[0046] When the spraying and crushing positions need to be adjusted, it is only necessary to rotate the rotary hand wheel 62 to adjust the C-shaped plate 61 to the different positions of the spraying pipe 31 .

[0047] Reference Figure 1 The rotating tank 2 is driven by a first motor 22, a driving gear 23, a driven gear 24, an auxiliary swivel 25 and an auxiliary rotating wheel 26. The first motor 22 is fixedly mounted on the base 1, the driving gear 23 is mounted on the output shaft of the first motor 22, the driven gear 24 is arranged around the outer wall of the rotating tank 2 and meshes with the driving gear 23, the auxiliary swivel 25 is fixedly mounted on the outer wall of the rotating tank 2, a rotating wheel base is symmetrically mounted on the base 1, and the auxiliary rotating wheel 26 is mounted on the rotating wheel base. The auxiliary swivel 25 and the auxiliary rotating wheel 26 are arranged in two groups, which can better assist the rotating tank 2 to rotate.

[0048] When in 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 synchronously drive the rotating tank 2 to rotate, and the auxiliary rotating ring 25 on the rotating tank 2 rotates synchronously. The auxiliary rotating wheel 26 can assist and accelerate the rotation of the rotating tank 2 while supporting the auxiliary rotating ring 25.

[0049] The implementation principle of a spray rotary granulation device in the embodiment of the present application is: When using the device, first pour the raw materials from the feed bin 21 into the rotating tank 2, then start the first motor 22, the output shaft of the first motor 22 drives the driving gear 23 to rotate, and the driven gear 24, the rotating tank 2, the auxiliary rotating ring 25, the auxiliary rotating wheel 26 and the rotating tank 2 rotate synchronously, and the raw materials inside the rotating tank 2 are constantly rolling.

[0050] Then, the rotating hand wheel 62 is turned to adjust the contact position between the C-shaped plate 61 and the shotcrete pipe 31, thereby determining the position of the shotcrete, and then the second motor 35 is started. The output shaft of the second motor 35 drives the shotcrete pipe 31 to rotate. When the inner wall of the shotcrete pipe 31 is separated from the outer wall of the C-shaped plate 61, the shotcrete pipe 31 enters the shunt pipe 32. The hydraulic pressure inside the shunt pipe 32 is enhanced, which can drive the breaker rod 51 and the arc block 53 on the breaker rod 51 to extend outward, and the arc block 53 slides from the first slot 55 to the second slot 56, and the synchronous breaker hammer 52 is moved from the shotcrete pipe 31 to the second slot 56. The slurry outlet 33 is relatively displaced outward, and the breaker 52 contacts the inner wall of the rotating tank 2 to break the materials that are adhered and compacted on the inner wall of the rotating tank 2; when the inner wall of the shotcrete pipe 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 shotcrete pipe 31. At this time, the hydraulic pressure inside the shunt pipe 32 is reduced, and the elastic force of the return spring 58 retracts, driving the breaker rod 51 to return to its original position. At this time, the arc-shaped block 53 is stuck on the first slot 55, the breaker 52 coincides with the shotcrete outlet 33, and the shotcrete outlet 33 stops spraying slurry outward.

[0051] The agitator 4 can knead the raw materials inside the rotating tank 2 into granular raw materials. After the breaker 52 breaks the raw materials that are stuck and compacted on the inner wall of the rotating tank 2, the agitator 4 can continue to granulate the fallen raw materials, while preventing the inner wall of the rotating tank 2 from sticking and compacting, and cleaning the inner wall in time to ensure work efficiency, reduce the frequency and difficulty of manual cleaning, thereby reducing maintenance costs, and at the same time improve the utilization rate of materials and reduce waste.

[0052] In addition, it should be noted that in the description of this application, unless otherwise clearly specified and limited, the terms "installed", "connected" and "connected" 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 a direct connection or an indirect connection through an intermediate medium, and it can be the internal connection of two elements.
