Description

Technical Field

[0001] The invention relates to the technical field of compound fertilizer production, in particular to a cooling and conveying device for preventing compound fertilizer from being overheated and denatured. Background Art

[0002] In the production process of compound fertilizer, from raw material preparation to finished product packaging, the whole process involves key steps such as granulation, primary screening, particle drying, cooling treatment, and secondary screening. Among them, the particle drying step is particularly critical. However, the drying process will increase the temperature of the particles. If the temperature is too high, it may cause adhesion between particles or lead to changes in physical properties, such as compaction and puffing.

[0003] However, the material transfer between the drying equipment and the screening device usually relies on a belt conveyor. During this period, the moving compound fertilizer particles are initially cooled by air cooling. However, in actual operation, due to the accumulation of particles on the conveyor belt, the heat dissipation effect of the particles at the bottom is poor, which increases the risk of adhesion and compaction between these particles. In addition, operators also need to pay attention to the larger compound fertilizer particles on the conveyor belt and redirect these larger particles to the primary screening step to ensure the consistency of product quality and avoid increasing the workload of subsequent equipment and causing blockage of the feed port.

DETAILED DESCRIPTION

[0037] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings.

[0038] In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein, and those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0039] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The term "in one embodiment" that appears in different places in this specification does not necessarily refer to the same embodiment, nor is it a separate or selective embodiment that is mutually exclusive with other embodiments.

[0040] Example 1

[0041] Reference Figure 1 to Figure 4 , which is the first embodiment of the present invention, provides a cooling and conveying device for preventing compound fertilizer from being overheated and denatured, comprising a conveyor belt 1, including two groups of partitions 11 arranged on both sides thereof;

[0042] The plurality of cooling units 2 include a clamping member 21 disposed on one side of the partition 11, an extension rod 22 disposed on one side of the clamping member 21, a clamping rod 23 disposed inside the extension rod 22, and a fan 24 fixedly connected to the inside of the clamping rod 23;

[0043] The multiple groups of material turning units 3 include a mounting plate 31 arranged on one side of the extension rod 22, multiple groups of control rods 32 arranged on the mounting plate 31, a screening assembly 33 arranged at the bottom of the control rods 32, and a material turning assembly 34 arranged at the bottom of the screening assembly 33.

[0044] Furthermore, the clamping member 21 is adjustable and fixedly clamped on the outer side of the partition 11;

[0045] The mounting plate 31 includes a long rod 311 disposed inside the extension rod 22, a shaft disc 312 disposed on one side of the long rod 311, and a crossbeam 313 disposed inside the shaft disc 312;

[0046] A torsion spring 314 is sleeved between the shaft disc 312 and the cross beam 313 .

[0047] Furthermore, the beam 313 array is provided with a plurality of sets of slots 3131;

[0048] The control rod 32 includes a clamping block 321 clamped at the bottom of the clamping slot 3131 , and a rod body 322 protruding from the bottom of the clamping block 321 .

[0049] Furthermore, the screening assembly 33 includes a threaded barrel 331 slidably connected to the inner side of the rod body 322 , a screw rod 332 disposed at the bottom of the threaded barrel 331 , and a toothed plate 333 disposed at the bottom of the screw rod 332 .

[0050] Furthermore, the turning assembly 34 includes a pulling member 341 disposed on the inner side of the rod body 322 , a rotating rod 342 disposed at the bottom of the pulling member 341 , a connecting rope 343 disposed at the bottom of the rotating rod 342 , and a scraper 344 disposed at the bottom of the connecting rope 343 .

[0051] It should be noted that if Figure 1 As shown, in this example, the conveyor belt 1 is designed to transport the compound fertilizer particles processed by the drying equipment to the subsequent screening process. In order to ensure that the particles do not overflow from both sides during the transportation process, the two sides of the conveyor belt 1 are firmly welded with partitions 11 to form an effective retaining edge structure. At the same time, multiple groups of cooling units 2 are arranged on the outside of the partition 11 to implement efficient air cooling and temperature reduction treatment on the moving compound fertilizer particles, thereby preventing the particles from sticking or hardening due to excessive temperature.

[0052] The cooling unit 2 is fixed to both sides of the conveyor belt 1 by its clamping parts 21. The clamping parts 21 adopt a flexible clamping mechanism, allowing the cooling unit 2 to slide and adjust its position along both sides of the conveyor belt unit, ensuring that the cooling effect can be optimized according to actual needs, providing a more uniform and effective cooling process.

[0053] Better, such as Figure 2 As shown, one side of the clamping member 21 is fixedly connected with a group of extension rods 22 extending upward, so that it is higher than the partition 11, so that the fan 24 is facing the conveyor belt 1. The upper end of the extension rod 22 is horizontally fixedly connected with a group of clamping rods 23, and the other end of the clamping rod 23 is a card interface fixedly connected with the base of the fan 24. Four groups of clamping rods 23 are respectively clamped on the four corners of the fan 24 to fix it. The spacing adjustment of the cooling unit 2 is achieved by the relative movement of the clamping members 21 at the bottom of the four groups of clamping rods 23, and modular installation can be achieved on both sides of the conveyor belt 1.

[0054] Preferably, the extension rod 22 and the clamping rod 23 can be made of aluminum rod material, which is an abundant raw material. The two are connected together by threads, which is easy to disassemble.

[0055] Better, such as Figure 2 As shown, two through slots are provided through the extension rod 22, the uppermost one of which is used to fix the connection clamp rod 23; and the lower one is used to fix the connection of the material turning unit 3. The long rod 311 is connected to the bottom sides of the fan 24 through the through slot, and the outer side of the long rod 311 is connected to the crossbeam 313. In addition, multiple groups of control rods 32 are linearly connected on the crossbeam 313, and a group of screening components 33 are fixedly connected to the bottom of the control rods 32, and a group of material turning components 34 are connected to the bottom of the screening components 33. The task of the screening component 33 is to filter the flowing compound fertilizer particles on the conveyor belt 1, which can effectively screen and simply break the compacted particles hidden in the particle group to reduce the equipment load in the subsequent processing steps. At the same time, the material turning component 34 is responsible for turning the particles accumulated at the bottom of the conveyor belt 1 upwards, increasing the chance of the particles contacting the airflow generated by the fan 24, thereby improving the cooling efficiency and preventing the particles from sticking or compacting due to overheating.

[0056] like Figure 3As shown, protruding shaft discs 312 are provided at positions near the cross beam 313 on both sides of the long rod 311, and the two groups of shaft discs 312 firmly clamp the cross beam 313 on the inner side of the long rod 311. Each group of shaft discs 312 is elastically connected to the cross beam 313 through a group of torsion springs 314, giving the cross beam 313 a continuous downward flipping tendency. In order to facilitate the adjustment and fixing of the position of the cross beam 313, multiple groups of slots 3131 are linearly distributed on it. The control rod 32 uses the clamping block 321 at its end to precisely dock with these slots 3131 to ensure a firm connection between the two. At the same time, the rod body 322 at the bottom of the control rod 32 connects the screening component 33 and the material turning component 34 together, realizing the coordinated operation of the entire system.

[0057] like Figure 4 As shown, the rod body 322 is hollow inside, and its bottom is rotatably connected to the threaded barrel 331 by snap-fitting, and the inner side of the threaded barrel 331 is threadedly connected to the screw 332, and the screw 332 can adjust its length by rotating; and a tooth plate 333 is welded to the bottom of the screw 332, and the tooth spacing of the tooth plate 333 can effectively filter out the compacted compound fertilizer particles.

[0058] Preferably, the tooth shape of the tooth plate 333 is designed to be Z-shaped, so that when it contacts the conveyor belt 1, its unique corner structure can effectively capture and separate the compacted particles to prevent these particles from mixing into the moving material flow.

[0059] In the arrangement of the tooth plate 333 and the screw rod 332, there is a through slot on the tooth plate 333, and a set of rotating rods 342 are arranged in the through slot. The rotating rod 342 not only passes through the screw rod 332, but also extends to the inner side of the rod body 322 and is connected to the pulling member 341. This design allows the rotating rod 342 to rotate freely inside the screw rod 332 and the rod body 322 to support the coordinated action of the entire system. In addition, a set of connecting ropes 343 made of flexible material are fixedly connected to the bottom of the rotating rod 342, so that the scraper 344 can be tilted on the conveyor belt 1 at an appropriate angle, thereby playing a good role in turning the flowing particles.

[0060] When in use, the operator can flexibly adjust the position of the cooling unit 2 according to specific needs, and firmly install it on both sides of the conveyor belt 1 to ensure that the fan 24 is precisely located above the conveyor belt 1. The long rod 311 is fixedly connected to the bottom of the fan 24 through the extension rod 22, and the crossbeam 313 always maintains a downward deflection force under the action of the built-in torsion spring 314. Ensure that the tooth plate 333 on the crossbeam 313 can fit tightly on the surface of the conveyor belt 1, and first perform a preliminary filtering treatment on the passing material. Then, the scraper 344 continues to turn the material over to ensure that all particles can evenly contact the cold air, thereby improving the overall cooling effect and effectively preventing adhesion and compaction between particles.

[0061] In summary, the device performs preliminary filtration of the material through the tooth plate 333, which can remove larger or compacted particles and ensure that the size of the particles in the subsequent turning process is relatively uniform. This helps to reduce the impact of large particles on the air cooling effect, so that the cold air can contact each particle more effectively. The redistribution of particles during the turning process increases the contact area between the particles and the cold air, promotes the rapid dissipation of heat, thereby improving the overall heat dissipation effect and preventing the particles from sticking or compacting due to high temperature.

[0062] Example 2

[0063] Reference Figure 4 to Figure 7 , which is the second embodiment of the present invention, and is different from the first embodiment in that: it also includes a pulling member 341 including a tensioner 3411 fixedly disposed at the inner end of the rod body 322, and a slider 3412 disposed at the bottom of the tensioner 3411;

[0064] The rotating rod 342 is fixedly connected to the bottom of the sliding block 3412 .

[0065] Furthermore, an arc groove 3221 is provided on the rod body 322;

[0066] The slider 3412 includes a protruding column 34121 fixedly disposed on its circumference and slides inside the limiting arc groove 3221 .

[0067] Furthermore, the tooth plate 333 includes a first tooth plate 3331 disposed at the bottom of the screw rod 332 , and a second tooth plate 3332 disposed at the bottom of the first tooth plate 3331 ;

[0068] The first tooth plate 3331 and the second tooth plate 3332 are slidably engaged with each other.

[0069] Furthermore, the first tooth plate 3331 includes a first tooth 33311 disposed at the bottom thereof, and a first crushing plate 33312 fixedly disposed at one side of the first tooth 33311;

[0070] The second tooth plate 3332 includes a second tooth 33321 disposed on one side thereof, and a second crushing plate 33322 fixedly disposed on one side of the second tooth 33321 .

[0071] Furthermore, the second tooth plate 3332 also includes a straight slot 33323 disposed at the center thereof, and a rack 41 is disposed on the inner wall of the straight slot 33323;

[0072] The rotating rod 342 includes a tooth column 3421 disposed in the middle section thereof;

[0073] The tooth column 3421 can drive the rack 41 to drive the second tooth plate 3332 to move.

[0074] It should be noted that the rod body 322 adopts a hollow structure, and a group of tensioners 3411 are fixedly connected to the upper end thereof. The tensioners 3411 can accurately sense the force exerted on the scraper 344 when the material flows, and then dynamically adjust the tooth spacing of the tooth plate 333.

[0075] like Figure 4 and Figure 5 As shown, an arc groove 3221 is provided on the rod body 322, and a group of sliders 3412 are fixedly connected to the bottom of the tensioner 3411 on the inner side of the rod body 322. The sliders 3412 are limited by the tensioner 3411 above them to slide in the rod body 322. A convex column 34121 is protruded outwardly from the circumference of the slider 3412, and the convex column 34121 is clamped in the arc groove 3221. The bottom of the slider 3412 is fixedly connected to the rotating rod 342. When the rotating rod 342 is subjected to an outward pulling force, it will drive the slider 3412 to move outward. In this process, due to the cooperation between the convex column 34121 and the arc groove 3221, the slider 3412 not only rotates along the arc groove path, but also moves downward synchronously.

[0076] Preferably, the design of the tensioner 3411 can be selected in different forms according to specific needs. First, a simple spring can be selected as the tensioner. This spring can stretch naturally when subjected to a large tensile force, and return to its original state after the external force is removed, providing basic elastic support. It has a simple structure and low cost, and is suitable for scenarios where the accuracy of tension adjustment is not high. Secondly, the tensioner 3411 can also adopt a complex adjustable tension device. It can be dynamically adjusted according to the material flow pressure borne by the scraper 344, which can not only improve the responsiveness and adaptability of the system, but also significantly enhance the effect of the filtering and turning process, ensuring the efficiency and stability of the entire production process.

[0077] Better, such as Figure 6 and Figure 7As shown, the middle section of the rotating rod 342 is provided with a tooth column 3421, and the position of the tooth column 3421 is just able to move up and down in the through slot of the tooth plate 333. The tooth plate 333 is composed of two groups of tooth plates, one of which is a first tooth plate 3331 as a main tooth plate, and the other is a second tooth plate 3332 which is slidably engaged with the bottom of the first tooth plate 3331. The second tooth plate 3332 is hidden under the first tooth 33311 of the first tooth plate 3331 or exposed in the middle of the first tooth 33311 of the first tooth plate 3331 by sliding. A straight slot 33323 is provided in the middle of the second tooth plate 3332 at the bottom, and a rack 41 is protruding on the side wall of the straight slot 33323. The rack 41 is meshed with the tooth column 3421. The rotation of the tooth column 3421 drives the rack 41 to move, thereby indirectly moving the second tooth plate 3332. Finally, the second tooth 33321 originally exposed in the middle of the first tooth 33311 is moved to below the first tooth 33311. The particle flow rate is changed by changing the spacing of the tooth plate 333.

[0078] A first crushing plate 33312 is welded to one side of each set of first teeth 33311, and a corresponding second crushing plate 33322 is welded to one side of each set of second teeth 33321, ensuring that the two correspond to each other in structure. When the second teeth 33321 slide along the straight notch 33323 to the bottom of the first teeth 33311, the second crushing plate 33322 also approaches the first crushing plate 33312. In this process, the relative movement between the two can effectively squeeze and disperse the compacted particles, breaking them into smaller units, thereby optimizing the filtering effect and preventing material clogging.

[0079] Preferably, the first tooth plate 3331 and the second tooth plate 3332 adopt a similar design, and both are equipped with Z-shaped teeth. This special shape of teeth can limit the compacted particles in the concave position, making them easier to be squeezed and crushed. The Z-shaped tooth design not only increases the contact area with the particles, but also ensures that the compacted particles can be firmly confined in the grooves of the teeth, which is convenient for subsequent processing. When the second tooth plate 3332 slides along the straight notch to the bottom of the first tooth plate 3331, the relative movement between the two groups of Z-shaped teeth can firmly clamp the compacted particles. Subsequently, the synergistic effect of the first crushing plate 33312 and the second crushing plate 33322 effectively achieves the extrusion and crushing of the particles through precise pressure application.

[0080] The other structures are the same as those in Example 1.

[0081] During use, in the initial state, the first tooth plate 3331 and the second tooth plate 3332 overlap each other, and the tooth plate 333 has a small spacing, which can filter out the compound fertilizer particles that are compacted due to heat. The particles will be screened by the tooth plate 333 and transferred to the scraper 344. The scraper 344 changes the plane structure of the conveyor belt 1 and turns the particles over, thereby increasing the cooling effect of the fan 24 on the particles.

[0082] When the flow rate of compound fertilizer particles is high, the flow rate will increase the pressure on the scraper 344. When the pressure increases to a value that exceeds the preset tension of the tensioner 3411, the scraper 344 will pull the connecting rope 343 and the rotating rod 342 to move outward, and then, with the cooperation of the protruding column 34121 and the arc groove 3221, the rotating rod 342 is driven by the slider 3412 to rotate along the arc groove path and move downward. Under the rotation of the rotating rod 342, the rotation of the tooth column 3421 drives the rack 41 to move, and then indirectly moves the second tooth plate 3332, and finally moves the second tooth 33321 originally exposed in the middle of the first tooth 33311 to the bottom of the first tooth 33311, and changes the particle flow rate by changing the spacing of the tooth plate 333. Among them, the arc groove 3221 is as shown in FIG. Figure 4 and 5 The figure shows an arc groove at a certain angle around the rod body 322, and the slider 3412 on the inner side of the rod body 322 is slidably engaged in the arc groove 3221 through the protrusion 34121. When the slider 3412 is pulled to move downward, the protrusion 34121 will move downward in the arc groove 3221, thereby causing the slider 3412 to rotate while moving downward. When the slider 3412 rotates and moves downward along the arc groove path, it will force the tooth column 3421 to rotate and move downward, and finally the rack 41 and the tooth column 3421 that were originally meshed together will move under the rotation drive of the tooth column 3421, thereby indirectly causing the second tooth plate 3332 to move, and finally the second tooth 33321 that was originally exposed in the middle of the first tooth 33311 will move to below the first tooth 33311.

[0083] When the flow rate is high, there will be more compacted particles on the tooth plate 333. At this time, during the movement of the second tooth plate 3332, the second crushing plate 33322 will be close to the first crushing plate 33312, thereby effectively squeezing and crushing the compacted particles.

[0084] In summary, the device drives the tooth column 3421 through the rotation of the rotating rod 342, and then drives the second tooth plate 3332 to slide along the straight slot 33323, so as to realize dynamic adjustment of the tooth plate spacing. The particle flow rate can be flexibly changed according to the actual flow demand to ensure the stability and adaptability of the system. In the initial state, the first tooth plate 3331 overlaps with the second tooth plate 3332, and the tight tooth spacing can effectively screen out the compound fertilizer particles that are compacted due to high temperature. When the second tooth plate 3332 moves, the second crushing plate 33322 approaches the first crushing plate 33312, so as to effectively crush the compacted particles and ensure that the particles are evenly dispersed.

[0085] It is important to note that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present invention may be modified or replaced by equivalents without departing from the spirit and scope of the technical solutions of the present invention, which should all be included in the scope of the claims of the present invention.
