Abstract
Description
Technical Field
[0001] This utility model relates to the field of organic fertilizer production technology, and in particular to a cooling device for granular organic fertilizer production. Background Technology
[0002] Organic fertilizer is processed from biological materials, animal and plant waste, and plant residues, eliminating toxic and harmful substances while enriching it with beneficial nutrients. It not only provides comprehensive nutrition for crops but also has a long-lasting effect, increasing and renewing soil organic matter, making it a key nutrient for green food production. Currently, cooling devices are needed in the organic fertilizer production process to rapidly reduce fertilizer temperature.
[0003] Existing cooling methods mainly involve air cooling, which rapidly blows cooling air onto the organic fertilizer to achieve the purpose of cooling. However, because the fertilizer lacks the necessary agitation, the cooling effect is often limited to the surface layer, and the temperature of the deeper layers of fertilizer is not significantly reduced. Therefore, a cooling device for granular organic fertilizer production is proposed. Utility Model Content
[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a cooling device for the production of granular organic fertilizer.
[0005] To achieve the above objectives, the present invention adopts the following technical solution:
[0006] A cooling device for granular organic fertilizer production includes a support frame, a cooling chamber at the top of the support frame, and a circular cooling cylinder inside the cooling chamber.
[0007] The cooling chamber has a liftable support block located below the cooling cylinder inside. In a preferred embodiment, the upper surface of the support block is designed with a U-shaped or V-shaped structure, and a cylinder is located at the bottom of the cooling chamber. A pneumatic rod at the output end of the cylinder extends into the cooling chamber and connects to the support block.
[0008] The bottom wall of the cooling chamber has two inclined sides designed as slopes, and several roller frames are set on the slopes. Rolling wheels are set on the inner side of the roller frames and synchronous sprockets are set on the outer side. The outer circumference of the cooling cylinder is fitted with an annular rolling friction strip, which rolls and rubs against the rolling wheels. Two double-row sprockets are set at the center of the bottom wall of the cooling chamber. The double-row sprockets are distributed on both sides and are connected by a chain belt drive. The two double-row sprockets are respectively connected to the synchronous sprockets on the same side by a chain belt drive.
[0009] In a preferred embodiment, the cooling chamber is designed as an octagonal cylinder, with end plates at both ends and openings at the center of each end plate.
[0010] In a preferred embodiment, the circumferential surface of the cooling cylinder is provided with evenly distributed air holes, and air inlets are provided at both ends of the cooling cylinder.
[0011] In a preferred embodiment, a servo motor is installed inside the cooling chamber, and the drive shaft at the output end of the servo motor is inserted into the center of one of the double-row sprockets installed inside the cooling chamber and maintains synchronous transmission with it.
[0012] In a preferred embodiment, the number of roller frames is at least two sets, and the roller frames are distributed at equal intervals along the length of the slope.
[0013] In a preferred embodiment, the number of rolling friction strips fitted onto the outer circumferential surface of the cooling cylinder is the same as the number of roller frames and their positions correspond one-to-one.
[0014] The beneficial effects of this utility model are:
[0015] The cooling device proposed in this solution solves the problem of unsatisfactory air cooling effect of granular organic fertilizer. The granular organic fertilizer is put into a circumferentially rotating cooling cylinder, and the rotation of the cooling cylinder accelerates the shaking of the organic fertilizer, thereby ensuring that the organic fertilizer can fully contact the cooling airflow, ensuring that the organic fertilizer granules are cooled quickly and comprehensively, which can improve the cooling effect. Moreover, the cooled organic fertilizer can be quickly poured out, which also facilitates personnel construction operations. Attached Figure Description

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.
[0022] In this embodiment, refer to Figure 1-4 A cooling device for granular organic fertilizer production includes a support frame 1, a cooling chamber 2 at the top of the support frame 1, and a circular cooling cylinder 3 inside the cooling chamber 2. (See attached image.) Figure 1 As shown, the cooling chamber 2 is designed as an octagonal cylinder. End plates are provided at both ends of the cooling chamber 2, and openings are formed in the center of each end plate. Cold air is introduced into the cooling chamber 2 through these openings to rapidly cool the fertilizer. Evenly distributed air holes 13 are formed on the circumferential surface of the cooling cylinder 3, and air inlets 4 are provided at both ends of the cooling cylinder 3.
[0023] As attached Figure 2 Or attached Figure 3 As shown, the cooling chamber 2 has a liftable support block 12 below the cooling cylinder 3 inside. The upper surface of the support block 12 is designed with a U-shaped or V-shaped structure. The upper surface of the support block 12 can fully fit against the bottom of the cooling cylinder 3. A cylinder 5 is installed at the bottom of the cooling chamber 2. A pneumatic rod at the output end of the cylinder 5 extends into the cooling chamber 2 and connects to the support block 12. The cooling cylinder 3 is raised by pushing the cylinder 5. It should be noted that, to ensure sufficient stability of the cooling cylinder 3 when raised, two sets of cylinders 5 and support blocks 12 can be used, with a certain distance between the support blocks 12 to ensure stable lifting of the cooling cylinder 3.
[0024] As attached Figure 2 As shown, the inclined sides of the bottom wall of the cooling chamber 2 are designed as slopes 6, and several roller frames 7 are respectively provided on the slopes 6. Rolling wheels 8 are provided on the inner side of the roller frames 7 and synchronous sprockets 9 are provided on the outer side. An annular rolling friction strip 14 is sleeved on the outer circumference of the cooling cylinder 3, and the rolling friction strip 14 rolls and rubs against the rolling wheels 8.
[0025] Here, the number of roller frames 7 is set to at least two sets, and the roller frames 7 are arranged at equal intervals along the length of the slope 6. The number of rolling friction strips 14 sleeved on the outer circumference of the cooling cylinder 3 is the same as that of the roller frames 7 and their positions correspond one-to-one. At the same time, the number of double-row sprockets 10 is also increased accordingly.
[0026] The reason for setting up multiple sets of roller frames 7 is to use the rollers 8 to provide stable support for the cooling cylinder 3. At the same time, when the rollers 8 rotate, the rolling friction can make the cooling cylinder 3 rotate synchronously.
[0027] Regarding the transmission process of the cooling cylinder 3: Two double-row sprockets 10 are set at the center of the bottom wall of the cooling chamber 2. The double-row sprockets 10 are distributed on both sides and are connected by a chain belt. The two double-row sprockets 10 are respectively connected to the synchronous sprockets 9 on the same side by a chain belt.
[0028] Two double-row sprockets 10 and the synchronizing sprockets 9 on both sides can be considered as a sprocket set. Multiple sprocket sets can be set, and each adjacent sprocket set is connected by a drive shaft to maintain the uniformity of motion.
[0029] The cooling chamber 2 is equipped with a servo motor 11. The drive shaft of the output end of the servo motor 11 is inserted into the center of one of the double-row sprockets 10 in the cooling chamber 2 and maintains synchronous transmission with it.
[0030] For the transmission process of one of the sprocket sets, see attached... Figure 2 As shown, when the servo motor 11 starts, it can control the rotation of the double-row sprocket 10 on the right side. When the double-row sprocket 10 rotates, it will cause the synchronous sprocket 9 on the same side and the double-row sprocket 10 on the left side to rotate through the chain belt. The double-row sprocket 10 on the left side will then drive the synchronous sprocket 9 on the left side to rotate through the chain belt. In this way, the rolling wheels 8 on both sides will rotate simultaneously under the drive of their respective synchronous sprockets 9, and the rotation direction will be the same. Therefore, the cooling cylinder 3 will rotate simultaneously with the rotation of the rolling wheels 8 due to rolling friction.
[0031] When cooling organic fertilizer, the fertilizer is first placed into the cooling cylinder 3. Then, the servo motor 11 is started, and the rolling friction between the rolling wheel 8 and the rolling friction strip 14 rotates the cooling cylinder 3, allowing cooling air to be introduced into the cooling chamber 2. During the rotation of the cooling cylinder 3, the fertilizer can fully contact the cold air and cool down rapidly. After the fertilizer temperature drops, the servo motor 11 is turned off. Then, the cooling cylinder 3 can be gradually tilted from a horizontal position by raising the lifting block 12. In this way, the material placed in the cooling cylinder 3 can naturally flow out through the air inlet 4, making the operation very convenient. Finally, as attached... Figure 4 As shown, the inner surfaces of the end plates at both ends of the cooling cylinder 3 are also provided with recessed material pouring ramps 15. The purpose of this design is to ensure that when the cooling cylinder 3 is tilted, the organic fertilizer inside the cooling cylinder 3 can slide out along the material pouring ramps 15, or even if it cannot slide out of the cylinder smoothly, the staff can still easily take it out.
[0032] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
