Description

Technical Field

[0001] This utility model relates to the field of agricultural fertilizer production equipment technology, and in particular to a steam granulation tank for bio-organic fertilizer. Background Technology

[0002] In the production of bio-organic fertilizer, granulation is a key step, which aims to transform powdery or granular raw materials into uniform granules through physical or chemical methods, making them easier to store, transport, and use. Steam granulation tanks use steam to heat and moisten materials, causing them to form granules under mechanical action. This technology is widely used in organic fertilizers, compound fertilizers, and other fields. However, existing steam granulation tanks have some problems in practical applications, affecting granulation quality and efficiency.

[0003] 1. Existing equipment is prone to uneven mixing when mixing materials, resulting in inconsistent particle composition and affecting fertilizer efficiency. Insufficient mixing may also lead to some materials being over-wetted or over-dryed, further affecting the uniformity and strength of the particles. 2. Existing equipment has low granulation efficiency, with some materials failing to form particles in time, leading to repeated granulation, increasing energy consumption and time costs. ； Therefore, we are launching a steam granulation tank for bio-organic fertilizer.

The base plate is fixedly connected to the lower end of the connecting box.

[0009] Preferably, the driving component includes a second driving motor and a belt. The output end of the second driving motor passes through the lower plate and is fixedly connected to a first pulley. The first pulley is connected to a second pulley via a belt drive. The upper ends of the first pulley and the second pulley are both fixedly connected to a third rotating rod. The outer surfaces of the two third rotating rods are both fixedly connected to a pressing roller. The second driving motor is fixedly connected to the lower left side of the lower plate.

[0010] Preferably, the mixing device includes a drive motor, the output end of which passes through the side plate and is fixedly connected to a main gear. A secondary gear is meshed with the front of the outer surface of the main gear. A plurality of rotating rods are fixedly connected to the left end of the main gear. A rotating rod is fixedly connected to the middle of the left end of the secondary gear. A plurality of stirring blades are fixedly connected to the outer surface of the rotating rod and the outer surface of the rotating rod, respectively. The drive motor is fixedly connected to the rear right end of the side plate.

[0011] Preferably, the blades of the plurality of stirring blades II face in the opposite direction to the blades of the plurality of stirring blades I, and the plurality of stirring blades II and the plurality of secondary gears are distributed in a staggered manner. The left end of the rotating rod II is movably connected to the left wall of the heating box via a bearing and the left end of the rotating rod I is movably connected to the front part of the right wall of the side plate via a bearing.

[0012] Preferably, both feeding plates are inclined at a 30-degree angle, and both feeding plates are connected to the interior of the connecting box, while the connecting box is not connected to the interior of the heating box.

[0013] Preferably, the granulation cylinder is connected to the interior of the heating box, the two scraper blades are respectively attached to the left and right sides of the granulation cylinder, and the height of the two scraper blades is the same as the height of the granulation cylinder. The front and rear sides of the distribution column are both arc-shaped.

[0014] Preferably, the upper ends of the two rotating rods are movably connected to the lower wall of the heating box via bearings, and the two rolling rollers are located on the left and right sides of the material distribution column, respectively. The left and right sides of the two rolling rollers are respectively in close contact with the left and right sides of the inner wall of the granulation cylinder.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] 1. The mixing device of this steam granulation tank effectively solves the problem of uneven mixing in existing equipment. The drive motor drives the main gear to rotate, which in turn makes the secondary gear rotate synchronously. The rotating rod 1 and rotating rod 2 connected to the main gear and the secondary gear respectively drive the stirring blade 1 and stirring blade 2 to rotate. Since the blades of stirring blade 2 and stirring blade 1 face opposite directions, they form opposing and staggered stirring forces on the material in the heating box during rotation, realizing the convective stirring effect and greatly improving the uniformity of material mixing. This allows the raw materials of bio-organic fertilizer to be fully integrated, ensuring the consistency of granule composition, effectively improving fertilizer efficiency, avoiding excessive wetting or drying of some materials due to insufficient mixing, and ensuring the uniformity and strength of the granules.

[0017] 2. In this utility model, in the main device, the mixed and heated material quickly enters the granulation cylinder through a structure that connects the granulation cylinder to the heating box. The drive motor 2 drives the pulley 1, which rotates synchronously via a belt. This drives the rotating rod 3 and the pressing roller fixed on its outer surface to operate efficiently. The arc-shaped structure of the distribution column evenly distributes the material entering the granulation cylinder, facilitating the pressing roller to evenly crush the material. This allows the material to be quickly extruded from the cylinder hole of the granulation cylinder and initially formed. At the same time, the scraper promptly scrapes off the material on the cylinder wall of the granulation cylinder, ensuring that the formed granules detach smoothly. Finally, the feeding plate, which is inclined at 30 degrees and equipped with a guide plate, uses gravity to allow the granulated material to flow quickly and smoothly into the connecting box. This significantly reduces the residence time of the material in the device, effectively avoids repeated granulation, reduces energy consumption and time costs, and greatly improves granulation efficiency.

[0028] Please see Figure 1-6 This utility model provides a technical solution:

[0029] A steam granulation tank for bio-organic fertilizer includes a heating box 1, a side plate 2 fixedly connected to the right end of the heating box 1, a mixing device 4 fixedly connected to the right end of the side plate 2, a box cover 3 hinged to the upper end of the heating box 1, a main body device 5 fixedly connected to the lower end of the heating box 1, and support legs 6 fixedly connected to the four corners of the lower end of the main body device 5.

[0030] In this embodiment, the main device 5 includes a connecting box 51. A lower plate 54 is fixedly connected to the lower end of the connecting box 51, and a granulation component 52 is fixedly connected to the lower end of the lower plate 54. A feeding plate 53 is fixedly connected to the lower left and lower right ends of the connecting box 51. The connecting box 51 is fixedly connected to the lower end of the heating box 1. The granulation component 52 includes a bottom plate 521. A scraper plate 523 is fixedly connected to the upper left and upper right ends of the bottom plate 521. A movable clamping device is attached to the upper middle of the bottom plate 521. The granulation cylinder 524 has a drive component 525 movably connected to the upper center of the bottom plate 521. A material distribution column 522 is fixedly connected to the upper center of the bottom plate 521. The bottom plate 521 is fixedly connected to the lower end of the connecting box 51. The drive component 525 includes a second drive motor 5251 and a belt 5252. The output end of the second drive motor 5251 passes through the lower plate 54 and is fixedly connected to a first pulley 5253. The first pulley 5253 is connected to the second pulley 5254 via the belt 5252. Rotating rods 5256 are fixedly connected to the upper ends of wheel 5253 and wheel 5254. Rolling rollers 5257 are fixedly connected to the outer surfaces of both rotating rods 5256. Drive motor 5251 is fixedly connected to the lower left side of the lower plate 54. Both feeding plates 53 are inclined at a 30-degree angle and are connected to the interior of the connecting box 51. The connecting box 51 is not connected to the interior of the heating box 1. The granulation cylinder 524 is connected to the interior of the heating box 1. Two scraper plates 5... The two scraper blades 523 are respectively attached to the left and right sides of the granulation cylinder 524, and the height of the two scraper blades 523 is the same as the height of the granulation cylinder 524. The front and rear sides of the material distribution column 522 are both arc-shaped. The upper ends of the two rotating rods 5256 are movably connected to the lower box wall of the heating box 1 through bearings. The two rolling rollers 5257 are respectively located on the left and right sides of the material distribution column 522. The left and right sides of the two rolling rollers 5257 are respectively attached to the left and right sides of the inner cylinder wall of the granulation cylinder 524.

[0031] Through the above scheme: the main device 5 plays a key role in the core granulation process of the bio-organic fertilizer steam granulation tank. The mixed and heated material smoothly enters the granulation cylinder 524 through the structure that connects the granulation cylinder 524 to the heating box 1. The granulation cylinder 524 is movably engaged with the middle of the upper end of the bottom plate 521, while the bottom plate 521 is fixed to the lower end of the connecting box 51. The drive component 525 starts to work. The second drive motor 5251, which is fixed to the lower left of the lower plate 54, has its output end passing through the lower plate 54, driving the first pulley 5253, which is fixed thereto, to rotate. The first pulley 5253 rotates synchronously with the second pulley 5254 through the belt 5252. 3. The rotating rod 5256 connected to the upper end of the second wheel 5254 rotates accordingly, thereby driving the rolling roller 5257 fixed on the outer surface of the rotating rod 5256 to rotate. The two rolling rollers 5257 are located on the left and right sides of the material distribution column 522, which has an arc-shaped structure and is fixed in the middle of the upper end of the bottom plate 521. It can evenly distribute the material entering the granulation cylinder 524, making it convenient for the rolling roller 5257 to evenly crush the material. The rolling roller 5257 is in close contact with the inner wall of the granulation cylinder 524, and works with the cylinder wall to apply pressure to the material, so that the material is squeezed out from the cylinder hole of the granulation cylinder 524 to complete the initial forming. During the granulation process, the scraper plate 523 fixed on the bottom plate 521... Playing a crucial role, its height is consistent with that of the granulation cylinder 524, and it is closely attached to the left and right sides of the granulation cylinder 524 respectively. It can promptly scrape off the material adhering to the cylinder wall, ensuring that the formed granules detach smoothly. Finally, the formed granules flow into the connecting box 51 from the lower left and right ends of the feeding plate 53, which is inclined at 30 degrees and communicates with the interior of the connecting box 51. The connecting box 51 is fixed to the lower end of the heating box 1 and is not connected to the interior of the heating box 1, avoiding interference from the heating process to subsequent granulation and discharge. The ingenious design of the main device 5 brings many significant benefits. The arc-shaped structure of the material distribution column 522 greatly improves the material diversion efficiency. As a result, the roller 5257 effectively ensures that it can apply force evenly to the material, preventing the material from accumulating in the granulation cylinder 524, thereby significantly improving the uniformity of granulation and ensuring the stability of the quality of the bio-organic fertilizer granules. The scraper 523 is closely fitted to the granulation cylinder 524 and is highly compatible, which can clean the material on the cylinder wall in time, effectively preventing the material residue from affecting the subsequent granulation process, ensuring the continuous and smooth progress of the granulation process, and improving production efficiency. The 30-degree inclined feed plate 53 cleverly utilizes gravity to allow the granular material to flow into the connecting box 51 quickly and smoothly, greatly reducing the residence time of the material in the device and further improving the overall production efficiency.

[0032] In this embodiment, the mixing device 4 includes a drive motor 41. The output end of the drive motor 41 passes through the side plate 2 and is fixedly connected to a main gear 42. A secondary gear 47 is meshed with the front of the outer surface of the main gear 42. A plurality of rotating rods 43 are fixedly connected to the left end of the main gear 42. A rotating rod 45 is fixedly connected to the middle of the left end of the secondary gear 47. A plurality of stirring blades 44 and a plurality of stirring blades 46 are fixedly connected to the outer surfaces of the rotating rods 43 and the outer surfaces of the rotating rods 45, respectively. The drive motor 41 is fixedly connected to the rear right end of the side plate 2. The blades of the stirring blades 46 face in the opposite direction to the blades of the stirring blades 44. The stirring blades 46 and the secondary gears 47 are staggered. The left end of the rotating rod 45 is movably connected to the left wall of the heating box 1 through a bearing. The other end of the rotating rod 45 is movably connected to the front of the right wall of the side plate 2 through a bearing.

[0033] Through the above scheme: the mixing device 4 plays an important role in mixing materials in the bio-organic fertilizer steam granulation tank. The drive motor 41, fixed to the rear right end of the side plate 2, is started. Its output end passes through the side plate 2, driving the main gear 42, which is fixedly connected to it, to rotate at high speed. The front of the outer surface of the main gear 42 meshes with the secondary gear 47, thereby driving the secondary gear 47 to rotate synchronously. Several rotating rods 43 connected to the left end of the main gear 42 rotate with the rotation of the main gear 42, and several stirring blades 44 fixed to the outer surface of the rotating rods 43 also move accordingly. At the same time, a rotating rod 45, fixedly connected to the middle of the left end of the secondary gear 47, rotates under the drive of the secondary gear 47, thereby causing several stirring blades 46 fixed to the outer surface of the rotating rod 45 to start working. Since the blades of the stirring blades 46 face opposite directions to the blades of the stirring blades 44, during rotation, the two interact with each other. The materials inside the heating box 1 generate opposing and staggered stirring forces. The left end of the second rotating rod 45 and the left end of the first rotating rod 43 are movably connected to the left wall of the heating box 1 via bearings. The other end of the second rotating rod 45 is movably connected to the front part of the right wall of the side plate 2 via bearings, ensuring stable rotation of the rotating rods and achieving thorough mixing of the materials. The meshing transmission of the main gear 42 and the secondary gear 47 ensures the stability and efficiency of power transmission, enabling rapid rotation of the stirring blades. The blades of the first stirring blade 44 and the second stirring blade 46 face opposite directions, creating a convective stirring effect, which greatly improves the uniformity of material mixing, ensures the full integration of the bio-organic fertilizer raw materials, and improves product quality. Several second stirring blades 46 and several secondary gears 47 are staggered, making full use of the internal space of the device, making the structure more compact and reasonable, increasing the stirring area within a limited space, and further improving stirring efficiency.

[0034] It should be noted that this utility model is a steam granulation tank for bio-organic fertilizer. When the bio-organic fertilizer steam granulation tank is in operation, first open the tank cover 3 with a damping device, put the raw materials into the heating chamber 1, then start the drive motor 41. Its output end drives the main gear 42 to rotate, which in turn drives the secondary gear 47 meshing with it to rotate. The rotating rod 43 connected to the left end of the main gear 42 and the rotating rod 45 inserted through the left end of the secondary gear 47 rotate accordingly. The stirring blades 44 and 46, fixed to their outer surfaces, with blades facing opposite directions, thoroughly and efficiently mix the raw materials in the heating chamber 1. The heating function of the heating chamber 1 is used to heat the materials. The mixed and heated bio-organic fertilizer material is then passed through the granulation cylinder 524 and the heating element... At the connection point of the hot box 1, the second drive motor 5251 starts working, and its output end drives the first pulley 5253 to rotate. Through the belt 5252, the second pulley 5254 rotates synchronously, thereby causing the rotating rod 5256 connected to the upper end of the first pulley 5253 and the second pulley 5254 to drive the crushing roller 5257 to rotate. The crushing roller 5257 crushes the material entering the granulation cylinder 524. The material is extruded from the cylinder hole of the granulation cylinder 524 and initially formed. The scraper plate 523 close to the granulation cylinder 524 scrapes off the material adhering to the cylinder wall during the granulation process, so that the particles are completely separated. Finally, the granulated material flows into the connecting box 51 from both sides along the feeding plate 53, which is inclined at 30 degrees and equipped with a guide plate, completing the entire granulation process.
