Description

Technical Field

[0001] This invention belongs to the technical field of compound fertilizer production equipment, specifically relating to a glycoside-containing compound fertilizer raw material conveying device for high-tower applications. Background Technology

[0002] High-tower granulation is one of the mainstream processes in compound fertilizer production. Its principle involves mixing molten urine or ammonium nitrate with preheated phosphate and potassium fertilizers at the top of a tower to form a slurry. The slurry is then sprayed through nozzles to form granules. The material cools and solidifies into granules as it falls. This process is widely used in compound fertilizer production. Glycoside-containing compound fertilizers are new functional fertilizers that incorporate glycoside bioactive components on the basis of traditional compound fertilizers. Glycoside components have the effects of improving soil microecology, promoting crop nutrient absorption, and enhancing crop resistance to stress. They have broad application prospects in the development of new fertilizers. However, glycoside components easily absorb moisture from the air, leading to surface wetness and increased viscosity of the raw materials, which in turn causes clumping.

[0003] In existing high-tower granulation production lines, the conveying of raw materials for glycoside-containing compound fertilizers is usually done by a combination of screw conveyors and bucket elevators. After the raw materials are batched on the ground, they are sent to the bucket elevator by screw conveyors and lifted to the top of the tower, which is tens or even hundreds of meters high, before entering the mixing tank for melting and pulping.

[0004] However, there are certain technical problems in the transportation process. There is a lack of effective online treatment for the agglomeration problem during transportation. Glycoside raw materials are prone to agglomeration during long-distance transportation due to environmental humidity or temperature fluctuations. If the agglomerated material is directly fed into the mixing tank at the top of the tower, it will lead to uneven mixing, affecting the granulation quality. In severe cases, agglomeration will also clog the granulation nozzles, causing production interruption. At the same time, the space at the top of the tower is limited, and the existing equipment is difficult to integrate drying, extrusion and crushing in a limited space. If the agglomerated material is returned to the ground for re-crushing and screening, it will result in ineffective transportation and energy waste, and at the same time reduce the continuity of production.

[0005] To avoid the aforementioned technical problems, a glycoside-containing compound fertilizer raw material conveying device for high-tower applications is provided to overcome the deficiencies in the prior art. Summary of the Invention

[0006] The purpose of this invention is to provide a glycoside-containing compound fertilizer raw material conveying device for high-tower applications, so as to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, the present invention provides the following technical solution: a glycoside-containing compound fertilizer raw material conveying device for high-tower applications, comprising a pre-conveying mechanism, a tower body, and a tower top processing mechanism, wherein the pre-conveying mechanism comprises a raw material silo and a screw feeding assembly connected in sequence, characterized in that: the tower top processing mechanism is located at the discharge end of the screw feeding assembly and is used to preheat and dry the glycoside-containing compound fertilizer raw material; The tower top processing mechanism includes: The material distribution cylinder is located at the top of the tower body and has multiple receiving bins inside for connecting to the discharge end of the screw feeding assembly. The extrusion mechanism is located below the receiving hopper; The extrusion mechanism includes a fixed screen plate and a rotating extrusion screen plate. The extrusion screen plate flips and cooperates with the fixed screen plate to crush the blocky raw material falling between the two, and the crushed material falls through the screen holes. The storage cylinder is located inside the distribution cylinder and is used to hold the material that falls down. The preheating and drying device is located at the receiving hopper and is used to blow hot air to assist in feeding and preheating the raw materials in the storage cylinder.

[0008] In a preferred embodiment, movable rods are fixedly connected to both sides of the extrusion screen plate near the top, and an arc-shaped groove is provided on the inner wall of the receiving bin for limiting the sliding of the movable rods, so as to stabilize the extrusion screen plate during rotation.

[0009] As a preferred embodiment, the outer wall of the receiving bin is provided with a reset mechanism, which includes an arc-shaped guide rod and a spring sleeved on the arc-shaped guide rod, so as to realize the reset after the extrusion screen plate is flipped.

[0010] In one preferred embodiment, the preheating and drying device includes a first pipe, a second pipe, and a third pipe; The first pipe is connected to the extrusion mechanism and is used to blow hot air onto the material on the screen plate to assist in feeding and preheating. The storage cylinder is equipped with a hot air jacket. The second pipe is connected to the hot air jacket and is used to introduce hot air into the hot air jacket to indirectly heat and dry the raw materials in the storage cylinder.

[0011] In a preferred embodiment, the third pipe penetrates and is inserted into the first pipe. A connecting groove is provided at the overlap of the first and third pipes. When the third pipe moves into the first pipe and the two connecting grooves overlap, hot air blows the material between the two screen plates through the connecting grooves.

[0012] In one preferred embodiment, multiple storage cylinders are provided and correspond to the receiving bins. The storage cylinders are fixedly connected to the inner walls of the distributing cylinders. A stirring rod is rotatably connected to a fixed axis inside the storage cylinders for use in drying the glycoside-containing compound fertilizer raw materials.

[0013] As a preferred embodiment, an eccentric block is fixedly connected to the outer wall of the diversion pipe, a connecting plate that abuts against the eccentric block is fixedly connected to one end of the first pipe near the diversion pipe, a second spring is sleeved on the first pipe, and a push plate that abuts against the extrusion screen plate is fixedly connected to the outer wall of the first pipe.

[0014] In a preferred embodiment, an annular pipe connected to a third pipe is fixedly connected to the outer wall of the distributing cylinder, a diversion pipe is rotatably connected to the center of the distributing cylinder, a bent pipe is fixedly connected to the outer wall of the annular pipe, the bent pipe is connected to the diversion pipe through a rotary joint, and a driving component is fixedly connected to the bottom end of the diversion pipe. The driving component is used to drive the diversion pipe and the stirring rod to rotate synchronously.

[0015] In a preferred embodiment, the driving component includes a driving gear, a driven gear, and a driving source. The driving gear meshes with the driven gear, the driving source drive shaft passes through the driving gear, the driven gear is connected to the stirring rod inside the storage cylinder, and the driving gear is coaxially and fixedly connected to the diverter pipe.

[0016] Compared with the prior art, the beneficial effects of the present invention are: This invention, through the setting of a closed-loop circulation crushing mechanism that combines a fixed screen plate with a flip-type extrusion screen plate, and a preheating and drying device set at the receiving hopper, has the effect of extruding and crushing agglomerated raw materials containing glycosides and compound fertilizers, and blowing hot airflow into the material between the screen plates at the same time to assist in feeding and preheating. Compared with the existing technology that returns agglomerated materials to the ground for reprocessing and lacks preheating function, this invention realizes the integration of online crushing, screening and instant preheating of agglomerated raw materials, avoiding ineffective transportation and energy waste. In this invention, the first pipe, the third pipe, and the connecting trough enable automatic switching of hot airflow between the extrusion station and the drying station. When the extrusion screen closes and extrudes, the connecting trough opens, and the hot airflow is concentrated and blown onto the material between the screens, providing real-time and precise preheating of the glycoside-containing raw material under extrusion. When the extrusion screen opens and the material is discharged, the connecting trough closes, and the hot airflow switches to the drying station. This allows the hot airflow to be concentrated and supplied at the moment of extrusion, improving preheating efficiency, reducing the temperature difference impact when the raw material enters the subsequent melting process, and effectively avoiding the decomposition and failure of heat-sensitive glycoside components due to excessive temperature difference.

[0017] This invention, in conjunction with a second pipeline consisting of multiple storage cylinders and flexible hoses, enables the overall rotation of the distribution cylinder to switch storage cylinder positions, and the flexible hoses to bend and maintain a continuous and unobstructed hot air path. This upgrades the intermittent operation of a single station to a parallel and continuous operation of multiple stations. Compared to the limitation that a single storage cylinder must stop to discharge material after drying and cannot continuously process the next batch of raw materials, this invention allows for the rotation of multiple storage cylinders, solving the problem of mutual interference between feeding and drying in the single-station mode, and realizing the parallel and continuous operation of multiple processes such as feeding, extrusion crushing, preheating, drying, and discharging.

[0020] The present invention will be further described below with reference to embodiments.

[0021] The following embodiments are used to illustrate the present invention, but should not be used to limit the scope of protection of the present invention. The conditions in the embodiments can be further adjusted according to specific conditions, and simple improvements to the method of the present invention under the premise of the concept of the present invention are all within the scope of protection claimed by the present invention.

[0022] Please see Figure 1 - Figure 7 The present invention provides a glycoside-containing compound fertilizer raw material conveying device for high-tower applications, comprising: The pre-conveying mechanism 1, the tower body 2, and the tower top processing mechanism, wherein the pre-conveying mechanism 1 includes a raw material bin and a screw feeding assembly connected in sequence; The tower top processing mechanism, located at the discharge end of the screw feeding assembly, is used to preheat and dry the glycoside-containing compound fertilizer raw materials. The tower top processing mechanism includes: The material distribution cylinder 3 is located at the top inside the tower body 2. The material distribution cylinder 3 is equipped with multiple material receiving bins 4 for connecting to the discharge end of the spiral feeding assembly. The extrusion mechanism is located below the receiving hopper 4; The extrusion mechanism includes a fixed screen plate 5 and a rotating extrusion screen plate 6. The extrusion screen plate 6 flips and cooperates with the fixed screen plate 5 to crush the blocky raw material falling between the two, and the crushed material falls through the screen holes. The extrusion screen plate 6 flips back and forth around its top hinge shaft, forming a gradually narrowing extrusion gap with the fixed screen plate 5, and progressively crushes the blocky raw material falling between the two. After crushing, the material with a particle size smaller than the screen hole size automatically falls through the screen hole, while the coarse particles that do not pass through the screen hole are intercepted by the screen plate and receive the next extrusion, thereby realizing closed-loop cycle crushing. Compared with the existing technology that returns agglomerated materials to the ground for reprocessing, this technology enables online crushing and screening of agglomerated raw materials, avoiding ineffective transportation and energy waste. The storage cylinder 7 is located inside the distribution cylinder 3 and is used to hold the material after it falls. A preheating and drying device is installed at the receiving hopper 4 to blow hot air to assist in feeding and preheat the raw materials in the storage cylinder 7; Movable rods 8 are fixedly connected to both sides near the top of the extrusion screen plate 6. The inner wall of the receiving bin 4 is provided with an arc-shaped groove for the movable rods 8 to slide in a limited position, so as to stabilize the extrusion screen plate 6 for flipping. When the extrusion screen plate 6 is flipped, the movable rod 8 slides along the arc groove to limit the movement trajectory of the extrusion screen plate 6 to the path determined by the arc groove, thereby ensuring that the extrusion screen plate 6 remains stable during the flipping process and avoiding uneven extrusion or material jamming caused by deviation. The outer wall of the receiving bin 4 is provided with a reset mechanism, which includes an arc-shaped guide rod 9 and a spring 10 sleeved on the arc-shaped guide rod 9, so as to realize the reset after the extrusion screen plate 6 is flipped. When the extrusion screen plate 6 is flipped under the drive of external force, the end of the movable rod 8 slides along the arc-shaped guide rod 9 and compresses the spring 10. When the external force is removed, the spring 10 releases its elastic potential energy, pushes the movable rod 8 to slide in the opposite direction along the arc-shaped guide rod 9, and drives the extrusion screen plate 6 to automatically return to the initial position, preparing for the next material feeding and extrusion, thereby realizing the continuous reciprocating operation of the extrusion screen plate 6. Spring 10 abuts against the end of movable rod 8 that passes through receiving bin 4, and the end of movable rod 8 has an opening that matches the arc-shaped guide rod 9.

[0023] The preheating and drying device includes a first pipe 11, a second pipe 12 and a third pipe 13; The first pipe 11 is connected to the extrusion mechanism and is used to blow hot air onto the material on the screen plate to assist in feeding and preheating. A hot air jacket is provided inside the storage cylinder 7. The second pipe 12 is connected to the hot air jacket and is used to introduce hot air into the hot air jacket to indirectly heat and dry the raw materials in the storage cylinder. The second pipe 12 is a flexible hose, and its outlet end is connected to the air inlet of the hot air jacket for introducing hot air into the hot air jacket. The hot air jacket is a jacketed cavity structure set in the inner wall of the distribution cylinder 3. The introduced hot air circulates in the jacket and indirectly heats and dries the material in the storage cylinder 7 through the jacket wall. The second pipe 12 is made of flexible hose and can bend and deform with the rotation and switching action of the distribution cylinder 3, so as to keep the hot air path continuous and unobstructed when the distribution cylinder 3 rotates, avoiding connection interference or pipe breakage caused by the rotation of the rigid pipe due to the rotation of the distribution cylinder 3. The third pipe 13 passes through and is inserted into the first pipe 11. A connecting groove is provided at the overlap of the first pipe 11 and the third pipe 13. When the third pipe 13 moves into the first pipe 11 and the two connecting grooves overlap, the hot air flows through the third pipe 13 and the connecting groove into the first pipe 11, and is concentrated and blown from the air outlet at the end of the first pipe 11 onto the material between the two screen plates, which helps the material to be fed and preheats the raw material in the extrusion state. When the third pipe 13 moves in the reverse direction and causes the two connecting slots to misalign, the hot air flow channel is cut off, and the hot air flow automatically switches to the second pipe 12 to continuously heat and dry the material in the storage cylinder 7. Through the reciprocating movement of the third pipe 13, the hot air flow is periodically switched between the extrusion station and the drying station. By distributing hot air in multiple channels, the temperature of the extrusion station and the storage station can be controlled in separate zones, which not only ensures the fluidity during extrusion but also prevents the material in the storage cylinder 7 from clumping again due to long-term accumulation.

[0024] The distributing cylinder 3 is equipped with multiple storage cylinders 7 corresponding to the receiving bin 4. The storage cylinders 7 are fixedly connected to the inner wall of the distributing cylinder 3. A stirring rod is rotatably connected to the fixed axis inside the storage cylinder 7, which is used to cooperate with the drying operation of the glycoside compound fertilizer raw materials. The bottom end of the storage cylinder 7 is equipped with a discharge port, and an electric control valve is installed at the discharge port to control the feeding. An eccentric block 14 is fixedly connected to the outer wall of the diversion pipe 20. A connecting plate 15 that abuts against the eccentric block 14 is fixedly connected to one end of the first pipe 11 near the diversion pipe 20. A push plate 17 that abuts against the extrusion screen plate 6 is fixedly connected to the outer wall of the first pipe 11. A second spring 16 for resetting the first pipe 11 is sleeved on the first pipe 11. One end of the second spring 16 abuts against the connecting plate 15, and the other end of the second spring 16 abuts against the storage cylinder 7. When the driving component drives the diversion pipe 20 to rotate continuously, the eccentric block 14 rotates synchronously with the diversion pipe 20, and its protruding part periodically pushes the connecting plate 15, overcoming the elastic force of the second spring 16 and driving the first pipe 11 to move closer to the diversion pipe 20. When the protruding part of the eccentric block 14 rotates past the connecting plate 15, the spring 16 releases its elastic force to push the first pipe 11 to reverse and reset. The reciprocating movement of the first pipe 11 drives the extrusion screen plate 6 to rotate synchronously through the push plate 17, and at the same time drives the third pipe 13 to move, causing the connecting groove to periodically open and close.

[0025] The continuous rotation of the diversion pipe 20 is converted into the reciprocating flipping motion of the extrusion screen plate 6, and at the same time, the flipping of the extrusion screen plate 6 and the hot air jet are precisely synchronized. When the extrusion screen plate 6 closes to extrude, the connecting groove opens and the hot air jet is concentrated and blown towards the material between the screen plates. When the extrusion screen plate 6 opens to drop the material, the connecting groove closes and the hot air jet is switched to the second pipe 12 to keep the material in the storage cylinder 7 warm.

[0026] The eccentric block 14 periodically pushes the connecting plate 15, causing the first pipe 11 to move back and forth, thereby realizing the periodic opening and closing of the connecting groove. By converting the rotational motion into the reciprocating motion required for the extrusion action, the synchronization of the extrusion screen plate 6 flipping and hot air jetting is realized. An annular pipe 18, which is connected to the third pipe 13, is fixedly connected to the outer wall of the distributing cylinder 3. A diversion pipe 20 is rotatably connected to the center of the distributing cylinder 3. A bent pipe 19 is fixedly connected to the outer wall of the annular pipe 18. The bent pipe 19 is connected to the diversion pipe 20 through a rotary joint. A driving component is fixedly connected to the bottom end of the diversion pipe 20. The driving component is used to drive the diversion pipe 20 and the stirring rod to rotate synchronously. The third pipe 13 passes through the receiving bin 4 and the distributing cylinder 3 and is connected to the annular pipe 18. The stirring rod continuously stirs the material during the drying process, so that the material accumulated at the bottom of the storage cylinder 7 is continuously turned up and dispersed. The positions of the material that was originally located at the edge and center of the cylinder wall are constantly exchanged, so that each part of the material can be evenly close to the hot air jacket of the inner wall of the storage cylinder 7. The top end of the diverter pipe 20 is connected to the heat source input end, which is a rotary joint type air inlet pipe. Its fixed end is connected to the air supply pipeline of the external hot air generator, and its rotating end is fixedly connected to the top end of the diverter pipe 20 and rotates synchronously with the diverter pipe 20. The rotary joint structure can stably deliver the hot air generated by the external hot air generator to the inside of the diverter pipe 20 while the diverter pipe 20 is rotating continuously. Then, the hot air is distributed to each of the first pipes 11 and the third pipes 13 through the diverter pipe 20, realizing uninterrupted supply of hot air under dynamic rotary sealing. The hot air jacket is filled with circulating hot air, which indirectly heats the material inside the cylinder through the jacket wall. The stirring action of the stirring rod effectively avoids uneven heating caused by static accumulation of materials, prevents local overheating of materials in contact with the jacket wall due to prolonged heating, and prevents residual moisture in the central area of ​​the material due to distance from the heat source. This ensures that the moisture content and temperature of the entire batch of raw materials remain consistent, thereby protecting the heat sensitivity of glycoside components. The driving component includes a driving gear 21, a driven gear 22, and a driving source. The driving gear 21 meshes with the driven gear 22. The driving source drive shaft passes through the driving gear 21. The driven gear 22 is connected to the stirring rod inside the storage cylinder 7. The driving gear 21 is coaxially and fixedly connected to the diversion pipe 20. The output end of the driving source drives the driving gear 21 to rotate, which in turn drives the driven gear 22, thereby driving the corresponding driven gear 22 to rotate. Furthermore, a toothed ring is fixedly connected to the outer wall of the distributing cylinder 3, and works with the driving component to drive the distributing cylinder 3 to rotate, thereby switching the corresponding storage cylinder 7. When the material in a certain storage cylinder 7 is dried and discharged through the electric control valve, the driving component drives the toothed ring to rotate through the transmission gear. The toothed ring drives the distributing cylinder 3 to rotate by a preset angle, so that the receiving bin 4 at the top of the next storage cylinder 7 is aligned with the discharge end of the spiral feeding component, and at the same time, the receiving bin 4 corresponding to the original storage cylinder 7 moves out of the feeding position.

[0027] Through this indexing rotation switching, the device can use multiple storage cylinders 7 in rotation without interrupting the feeding of the front conveying mechanism 1, so as to realize the parallel operation of multiple processes such as feeding, drying and discharging, which can significantly improve the continuity of the top processing and the throughput per unit time.

[0028] The working principle and usage process of this invention: The raw material bin of the front conveying mechanism 1 and the screw feeding assembly lift and convey the glycoside-containing compound fertilizer raw material to the top of the tower body 2. A certain receiving bin 4 in the distribution cylinder 3 is aligned with the discharge end of the screw feeding assembly. After the raw material falls into the receiving bin 4, it falls between the fixed screen plate 5 and the extrusion screen plate 6. The driving component drives the diversion pipe 20 to rotate continuously, and the eccentric block 14 on the diversion pipe 20 rotates synchronously with it. The protruding part of the eccentric block 14 periodically pushes the connecting plate 15, overcoming the elastic force of the second spring 16 and driving the first pipe 11 to move closer to the diversion pipe 20. The first pipe 11 pushes the extrusion screen plate 6 to rotate around its top hinge axis through the push plate 17. At the same time, the movable rod 8 slides along the arc groove on the inner wall of the receiving bin 4. The end of the movable rod 8 slides along the arc guide rod 9 and compresses the first spring 10. When the protruding part of the eccentric block 14 rotates past the connecting plate 15, the second spring 16 releases its elastic force to push the first pipe 11 to return to its original position. At the same time, the first spring 10 releases its elastic potential energy to push the movable rod 8 to slide in the opposite direction along the arc guide rod 9, driving the extrusion screen plate 6 to automatically return to its original position. This cycle repeats, causing the extrusion screen plate 6 to rotate around its top hinge axis, forming a gradually narrowing extrusion gap with the fixed screen plate 5, and progressively extruding and crushing the blocky raw material falling between them. After crushing, materials with a particle size smaller than the screen hole size automatically fall through the screen hole into the storage cylinder 7. Coarse particles that do not pass through the screen hole are intercepted by the screen plate and subjected to the next compression, forming a closed-loop crushing cycle. While the extrusion screen plate 6 is flipping, the reciprocating movement of the first pipe 11 drives the third pipe 13 to move synchronously. When the extrusion screen plate 6 closes and extrudes, the first pipe 11 moves towards the diversion pipe 20. The third pipe 13 is inserted into the first pipe 11 so that the two connecting grooves overlap. The hot air flows through the third pipe 13 and the connecting groove into the first pipe 11. It is concentrated and blown from the air outlet at the end of the first pipe 11 towards the material between the two screen plates to assist in feeding and preheat the raw material in the extrusion state. When the extrusion screen plate 6 opens and resets, the first pipe 11 moves in the opposite direction, causing the two connecting slots to misalign. The hot airflow channel is cut off, and the hot airflow is automatically switched to the second pipe 12. The second pipe 12 is a flexible hose, and its outlet is connected to the air inlet of the hot air jacket on the inner wall of the storage cylinder 7. The hot airflow enters the hot air jacket and circulates in the jacket. It indirectly heats and dries the material in the storage cylinder 7 through the jacket wall. The second pipe 12 bends and deforms with the rotation and switching action of the distribution cylinder 3 to keep the hot air path continuous and unobstructed. The top of the diverter pipe 20 is connected to an external hot air generator via a rotary joint-type air inlet pipe. The hot air is stably delivered while the diverter pipe 20 is continuously rotating. At the same time, the drive source output shaft in the drive component passes through the drive gear 21. The drive gear 21 is coaxially fixedly connected to the diverter pipe 20 and drives it to rotate. The drive gear 21 also meshes with the driven gear 22. The driven gear 22 is connected to the stirring rod in the storage cylinder 7, driving the stirring rod to rotate on a fixed axis in the storage cylinder 7. During the drying process, the stirring rod continuously stirs the material, causing the material accumulated at the bottom of the storage cylinder 7 to be continuously turned up and dispersed. The material positions at the edge and center of the cylinder wall are constantly exchanged, so that each part of the material is evenly close to the hot air jacket of the inner wall of the storage cylinder 7. When the material in a certain storage cylinder 7 is dried, the electric control valve at the bottom outlet opens to discharge the material. After emptying, the drive unit drives the gear ring fixedly connected to the outer wall of the distribution cylinder 3 through the transmission gear, so that the distribution cylinder 3 rotates as a whole by a preset angle, aligning the receiving bin 4 at the top of the next storage cylinder 7 with the discharge end of the screw conveyor assembly. At the same time, the receiving bin 4 corresponding to the original storage cylinder 7 moves out of the feeding position. Multiple storage cylinders 7 are used in rotation without interrupting the feeding of the front conveyor mechanism 1, so as to realize the parallel and continuous operation of multiple processes such as feeding, crushing, drying and discharging.
