Description

Technical Field

[0001] This application relates to the field of organic fertilizer production technology, and in particular to a raw material granulation device for organic fertilizer production. Background Technology

[0002] In the production of organic fertilizer, the rotary drum granulator is a commonly used piece of equipment. It uses the rotation of the drum to make the organic fertilizer raw materials tumble and move continuously inside the drum, thereby achieving granulation.

[0003] However, in actual use, most existing organic fertilizer rotary drum granulators use a simple pipeline injection method to supply steam or binders into the drum.

[0004] Specifically, regarding steam supply, typically only a single, simple steam pipe is installed, through which steam is directly introduced into the rotating drum. This single steam supply method results in extremely uneven steam distribution within the drum, leading to significant temperature differences between different regions. Regions with excessively high temperatures may cause the raw materials to over-react, resulting in overly hard and brittle particles, affecting particle quality and strength; while regions with excessively low temperatures may result in insufficient reaction of the raw materials, failing to form a good particle structure and causing loose particles, thus affecting the granulation effect.

[0005] The adhesive is injected into the rotating drum through a simple pipe, allowing the adhesive to mix fully and evenly with the organic fertilizer raw materials. Uneven distribution of the adhesive within the rotating drum can cause some raw materials to come into excessive contact with the adhesive, forming overly sticky clumps that affect the uniformity and flowability of the granules. Meanwhile, some raw materials may not be able to bond together effectively due to insufficient adhesive, making it difficult to form a stable granule structure and affecting the granulation effect.

[0006] To address the aforementioned issues, a raw material granulation device for organic fertilizer production is now designed. Utility Model Content

[0007] This application provides a raw material granulation device for organic fertilizer production, which solves the problem in related technologies where some organic fertilizer rotary drum granulators mostly use simple pipeline injection when supplying steam or binder into the drum, resulting in uneven temperature and binder distribution inside the drum.

[0008] In a first aspect, a raw material granulation apparatus for organic fertilizer production is provided, comprising: A base on which a rotatable drum is mounted, and a driving component is mounted on the base to drive the drum to rotate. The rotating drum is equipped with a steam supply unit and a liquid supply unit. The steam supply unit includes a main steam supply pipe arranged inside the rotating drum, and multiple branch pipes arranged at the bottom of the main steam supply pipe, with multiple vent holes opened on the branch pipes; The liquid supply unit includes a liquid supply tank, a pump body mounted on the liquid supply tank, a main pipe arranged inside the rotating drum, and a branch pipe located at the bottom of the main pipe, with multiple nozzles at the bottom of the branch pipe.

[0009] In some embodiments, the rotating drum has a cavity inside for containing organic fertilizer raw materials, and the two ends of the rotating drum are a feed inlet and a discharge outlet, respectively.

[0010] In some embodiments, a support mechanism is provided on the base; The support mechanism includes four rectangularly distributed support seats on the base, a rotating shaft rotatably mounted on the support seats, and rollers mounted on the rotating shaft. The outer sides of two adjacent rollers are slidably fitted with annular slide rails, and the rotating drum is disposed inside the two annular slide rails.

[0011] In some embodiments, the support mechanism further includes two fixed seats disposed on the base, the two fixed seats being located between two adjacent support seats, and a limit ring being disposed above the fixed seats, the limit ring being located on both sides of the annular slide rail.

[0012] In some embodiments, the driving component includes an annular rack mounted on a rotating drum, a bearing seat mounted on a base, a rotatable shaft II disposed within the bearing seat, and a gear and a pulley I respectively disposed at both ends of the shaft II, the gear meshing with the annular rack; The driving component also includes a drive motor and a reducer. The output shaft of the drive motor is connected to the input shaft of the reducer. The output shaft of the reducer is provided with a second pulley. The second pulley and the first pulley are connected by a belt drive.

[0013] In some embodiments, the main steam supply pipe and the main pipe are arranged parallel to each other inside the rotating drum; Support frames are arranged at both ends of the base, and the two ends of the main pipe and the steam supply main pipe extend outward. The two support frames are respectively connected to the two ends of the main pipe and the steam supply main pipe.

[0014] In some embodiments, the branch pipe is Y-shaped, the sub-pipe is T-shaped, and a plurality of the branch pipes and sub-pipes are staggered along the length of the rotating drum.

[0015] This application provides a raw material granulation device for organic fertilizer production. Through the cooperation of a steam supply unit and a liquid supply unit, steam and binder are uniformly sprayed into the interior of the rotating drum, making the temperature and humidity of each area inside the drum more uniform. This avoids differences in raw material reaction caused by local excessively high or low temperatures or uneven humidity, thereby improving the mixing uniformity of organic fertilizer raw materials and steam. At the same time, the uniformly sprayed binder can fully bond the raw material particles, avoiding differences in particle strength caused by uneven distribution of binder, improving the mixing uniformity of raw materials and binder, and facilitating the formation of stable quality particles.

[0016] Steam and binder can be evenly supplied to organic fertilizer raw materials through steam supply unit and liquid supply unit, so that the raw materials can react and bind evenly during granulation, so that the raw material particles form a good bonding structure and improve the granulation effect.

Detailed Implementation

[0020] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0021] This application provides a raw material granulation device for organic fertilizer production, which can solve the problem in related technologies where some organic fertilizer rotary drum granulators mostly use simple pipeline injection when supplying steam or binder into the drum, resulting in uneven temperature and binder distribution inside the drum.

[0022] Please see Figures 1-3 A raw material granulation device for organic fertilizer production includes: a base 1 on which a rotatable drum 2 is disposed, and a driving component 3 on the base 1 for driving the drum 2 to rotate; The rotating drum 2 is equipped with a steam supply unit 4 and a liquid supply unit 5. The steam supply unit 4 includes a main steam supply pipe 41 arranged inside the rotating drum 2, and multiple branch pipes 42 arranged at the bottom of the main steam supply pipe 41. Multiple vent holes 43 are opened on the branch pipes 42. The branch pipes 42 are connected to the main steam supply pipe 41, and one end of the main steam supply pipe 41 is connected to an external steam generator.

[0023] The liquid supply unit 5 includes a liquid supply tank 51, a pump body 52 mounted on the liquid supply tank 51, a main pipe 53 arranged inside the rotating drum 2, and a branch pipe 54 located at the bottom of the main pipe 53. Multiple nozzles 55 are mounted at the bottom of the branch pipe 54. The branch pipe 54 is connected to the main pipe 53, the inlet of the pump body 52 is connected to the liquid supply tank 51, and the outlet of the pump body 52 is connected to the main pipe 53.

[0024] The liquid supply tank 51 is used to hold the adhesive. The liquid supply tank 51 is equipped with a feeding port and a stirrer is installed inside the liquid supply tank 51.

[0025] The drive unit 3 installed on the base 1 starts to work, driving the rotatable drum 2 to rotate.

[0026] An external steam generator produces steam, which enters the steam supply main pipe 41 through a pipe connected to one end of the main pipe 41. The main pipe 41 is located inside the rotating drum 2, and multiple branch pipes 42 at its bottom are connected to the main pipe 41. Steam flows from the main pipe 41 into each branch pipe 42, and then is evenly sprayed into the interior of the rotating drum 2 through multiple vent holes 43 opened on the branch pipes 42.

[0027] The uniformly injected steam can provide a suitable temperature and humidity environment for organic fertilizer raw materials, promote chemical reactions and physical changes between raw materials, and facilitate the formation and solidification of particles.

[0028] The supply tank 51 is used to hold the adhesive. An agitator inside the supply tank 51 agitates the adhesive to keep it in a uniform state. The pump body 52 starts working. The inlet of the pump body 52 is connected to the supply tank 51. The adhesive in the supply tank 51 is drawn out and pumped into the main pipe 53. The branch pipe 54 at the bottom of the main pipe 53 is connected to the main pipe 53. Multiple nozzles 55 are installed at the bottom of the branch pipe 54. The adhesive flows from the main pipe 53 into the branch pipe 54 and is then evenly sprayed onto the organic fertilizer raw materials in the rotating drum 2 through the nozzles 55.

[0029] Evenly sprayed adhesive can help the raw material particles bond together better, forming a stable particle structure.

[0030] During the rotation of the rotating drum 2, the organic fertilizer raw materials continuously tumble and move inside the drum. At the same time, steam and binder are evenly supplied to the raw materials according to the above process. Under suitable temperature, humidity and bonding conditions, the raw materials gradually gather and bind to form granules of uniform size and regular shape, thus completing the granulation process.

[0031] By coordinating the steam supply unit 4 and the liquid supply unit 5, steam and adhesive are evenly sprayed into the interior of the rotating drum 2, making the temperature and humidity of each area inside the rotating drum 2 more uniform. This avoids differences in raw material reaction caused by localized excessively high or low temperatures or uneven humidity, thereby improving the mixing uniformity of organic fertilizer raw materials and steam. At the same time, the evenly sprayed adhesive can fully bond the raw material particles, avoiding differences in particle strength caused by uneven distribution of adhesive, thus improving the mixing uniformity of raw materials and adhesive and facilitating the formation of stable quality particles.

[0032] Steam and binder can be evenly supplied to the organic fertilizer raw materials through steam supply unit 4 and liquid supply unit 5, so that the raw materials can react and bind evenly during the granulation process, forming a good bonding structure between the raw material particles and improving the granulation effect.

[0033] The steam supply unit 4 and the liquid supply unit 5 are matched with the structure of the rotating drum 2, which can ensure the stability and reliability of the equipment during operation.

[0034] The steam supply unit 4 and the liquid supply unit 5 are independent of each other and do not interfere with each other, making the maintenance and repair of the equipment more convenient.

[0035] like Figure 1 and Figure 2 As shown, the rotating drum 2 in this embodiment has a cavity inside for containing organic fertilizer raw materials, and the two ends of the rotating drum 2 are the inlet 21 and the outlet 22, respectively.

[0036] Organic fertilizer raw materials are fed into the cavity inside the rotating drum 2 through the feed inlet 21 at one end of the rotating drum 2; During the rotation of the drum 2, the combined action of steam and adhesive, the organic fertilizer raw materials gradually gather and bind together to form uniformly sized and regularly shaped granules. As the drum rotates, these granules move to the discharge port 22 at the other end of the drum 2 and are discharged from the drum 2 in an orderly manner.

[0037] like Figure 1 and Figure 5 As shown, in one embodiment, a support mechanism 6 is provided on the base 1. The support mechanism 6 includes four rectangular support seats 61 arranged on the base 1, a rotating shaft 62 rotatably arranged on the support seats 61, and rollers 63 arranged on the rotating shaft 62; annular slide rails 64 are slidably fitted on the outer sides of two adjacent rollers 63, and the rotating cylinder 2 is arranged inside the two annular slide rails 64.

[0038] When the driving component 3 drives the rotating drum 2 to rotate, the rotating drum 2 will drive the annular slide rail 64 to rotate together. Since the roller 63 and the annular slide rail 64 are in sliding fit, the annular slide rail 64 will slide along the surface of the roller 63 during rotation. The roller 63 reduces this sliding friction by its own rotation, so that the rotating drum 2 can rotate stably and continuously under the support of the annular slide rail 64.

[0039] By converting the rotational motion of the drum 2 into the relative sliding between the annular slide rail 64 and the roller 63 and the rotational motion of the roller 63 itself, the force generated when the drum 2 rotates is effectively dispersed, thereby improving the stability and reliability of the equipment operation.

[0040] like Figure 5As shown, further, the support mechanism 6 in this embodiment also includes two fixed seats 65 disposed on the base 1. The two fixed seats 65 are located between two adjacent support seats 61. A limiting ring 66 is disposed above the fixed seat 65. The limiting ring 66 is located on both sides of the annular slide rail 64.

[0041] On the base 1, four rectangular support seats 61 form the basic frame of the support mechanism, providing the main support for the rotating cylinder 2. Two fixed seats 65 are set between two adjacent support seats 61, and limit rings 66 are installed above them. The limit rings 66 are located on both sides of the annular slide rail 64, forming a limit structure for the annular slide rail 64.

[0042] Specifically, the limiting rings 66 located on both sides of the annular slide rail 64 play a lateral limiting role, preventing the annular slide rail 64 from shifting laterally due to centrifugal force or other factors during rotation, and ensuring that the annular slide rail 64 and the rotating drum 2 always rotate stably on the predetermined track.

[0043] like Figure 2 and Figure 2 As shown, the driving component 3 further includes an annular rack 31 mounted on the rotating drum 2 and a bearing seat 32 mounted on the base 1. A rotatable shaft 33 is mounted inside the bearing seat 32. A gear 34 and a pulley 35 are respectively mounted at both ends of the shaft 33. The gear 34 meshes with the annular rack 31. The driving component 3 also includes a drive motor 38 and a reducer 36. The output shaft of the drive motor 38 is connected to the input shaft of the reducer 36. A pulley 37 is mounted on the output shaft of the reducer 36. The pulley 37 and the pulley 35 are connected by a belt drive.

[0044] After the drive motor 38 starts, its output shaft begins to rotate, transmitting power to the input shaft of the reducer 36 connected to it. The reducer 36 reduces the speed and increases the torque.

[0045] The power adjusted by the reducer 36 is transmitted from its output shaft to the second pulley 37. The second pulley 37 is connected to the first pulley 35 located at one end of the second shaft 33 via a belt. When the second pulley 37 rotates, it drives the belt to move, which in turn causes the first pulley 35 to rotate, thus realizing the transmission of power from the drive motor 38 and the reducer 36 to the second shaft 33.

[0046] The second rotating shaft 33 can rotate within the bearing housing 32. Since the gear 34 meshes with the annular rack 31 set on the rotating drum 2, when the second rotating shaft 33 drives the gear 34 to rotate, the teeth of the gear 34 will push the teeth of the annular rack 31 in sequence, thereby driving the rotating drum 2 to rotate around its own axis. During the rotation of the drum, the organic fertilizer raw materials inside will continuously tumble and mix under the action of centrifugal force and friction, realizing the granulation process.

[0047] like Figure 1 and Figure 4 As shown, in one embodiment, the steam supply main pipe 41 and the main pipe 53 are arranged in parallel inside the rotating drum 2; support frames 7 are arranged at both ends of the base 1, and the two ends of the main pipe 53 and the steam supply main pipe 41 extend outward, and the two support frames 7 are respectively connected to the two ends of the main pipe 53 and the steam supply main pipe 41.

[0048] The steam supply main pipe 41 and the main pipe 53 are arranged in parallel inside the rotating drum 2, so that the steam and adhesive can be evenly distributed along the axial direction of the rotating drum 2.

[0049] The support frames 7 arranged at both ends of the base 1 serve to fix and support the main pipe 53 and the steam supply main pipe 41.

[0050] Specifically, the two support frames 7 are connected to the two ends of the two pipes respectively, which securely suspends the pipes inside the rotating drum 2 and avoids interfering with the rotation of the rotating drum 2, ensuring that the pipes can stably deliver steam and adhesive into the rotating drum 2.

[0051] like Figure 4 As shown, in one embodiment, the branch pipe 42 is Y-shaped, the branch pipe 54 is T-shaped, and the plurality of branch pipes 42 and branch pipes 54 are staggered along the length of the rotating drum 2.

[0052] The Y-shaped branch pipe 42 is connected to the main steam supply pipe 41, which can divert the steam in the main steam supply pipe 41, so that the steam can be transported into the drum in multiple directions and paths.

[0053] Similarly, the T-shaped branch pipe 54 is connected to the main pipe 53, distributing the material in the main pipe 53 to different directions and areas.

[0054] Multiple branch pipes 42 and branch pipes 54 are staggered along the length of the rotating drum 2, so that steam and adhesive can be distributed at different locations and levels of the rotating drum 2.
