Description

Technical Field

[0001] This utility model relates to the field of biomass energy utilization technology, and in particular to a cooling device for biomass pellet processing. Background Technology

[0002] Biomass pellets are produced by cold-forming and densifying crushed biomass straw, forestry waste, and other raw materials using pressure rollers and ring dies at room temperature. The density of the raw materials is generally 0.1-0.13 t / m3, and the density of the pellets after forming is 1.1-1.3 t / m3. This process facilitates storage and transportation and greatly improves the combustion performance of biomass.

[0003] In existing technologies, traditional particle cooling processes use unidirectional cooling paths, such as vertical drop or simple conveyor belts, resulting in short particle residence time, insufficient heat exchange, easy particle aggregation, difficulty in internal heat dissipation, and difficulty in removing impurities simultaneously.

[0004] Therefore, a cooling device for biomass pellet processing is proposed. Utility Model Content

Telescopic columns are fixedly connected to the bottom of both the inclined frame and the discharge plate. A support rod is fixedly connected to the bottom of the telescopic column, and a first compression spring is fixedly connected to the inside of the telescopic column. The support rod is fixedly connected to the inside of the vertical air-conditioned cabinet, and vibration components are movably connected to the bottom and rear of the vertical air-conditioned cabinet.

[0008] Preferably, the reciprocating air-sweeping mechanism includes servo motors fixedly connected to both sides of the vertical air-cooled cabinet, the output end of the servo motors is fixedly connected to a rotating bracket, and a cooling fan is rotatably connected to the inner side of the rotating bracket.

[0009] Preferably, an extension shaft is fixedly connected to the front side of the cooling fan, the extension shaft is rotatably connected to the front side of the rotating bracket, a linkage gear is fixedly connected to the front side of the extension shaft, a torsion spring is fixedly connected to the rear side of the linkage gear, and the torsion spring is fixedly connected to the front side of the rotating bracket.

[0010] Preferably, a drive motor is fixedly connected to the front side of the rotating bracket, and an incomplete tooth is fixedly connected to the output end of the drive motor, the incomplete tooth being movably connected to the outside of the linkage gear.

[0011] Preferably, the vibration assembly includes a multi-section telescopic rod tube fixedly connected to the bottom of the vertical air-conditioner, the multi-section telescopic rod tube fixedly connected to the top of the front side of the support base plate, a support slide rail fixedly connected to the rear side of the top of the support base plate, and the vertical air-conditioner slidably connected to the front side of the support slide rail.

[0013] Preferably, the top of the vertical air-cooled cabinet is fixedly connected to a feeding port, and the bottom of the vertical air-cooled cabinet is fixedly connected to a discharging port.

[0014] Preferably, the front side of the vertical air-conditioned cabinet is rotatably connected to a magnetic door.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] 1. This application addresses the problem of short residence time caused by the unidirectional path in traditional particle cooling by setting up a vibrating screen dispersion mechanism. By using four sets of inclined frames and feeding plates in opposite directions to form a segmented cooling path, after the particles enter from the feed port, they roll down at the high points of each inclined frame by inertia and gravity, which greatly extends the residence time in the vertical air-cooled cabinet, allowing the low-temperature air and particles to fully exchange heat. For the problem of particles easily accumulating and having difficulty in internal heat dissipation, the inclined frames and feeding plates are supported by an elastic structure. The impact of particle feeding and path exchange causes them to vibrate, which drives the particles to disperse, avoids stacking, and increases the heat dissipation area. At the same time, the screen and waste drawer at the top of the inclined frame can remove particles and impurities that do not meet the requirements during vibration, solving the problem of impurities being difficult to remove simultaneously. In addition, the support structure design ensures that even with a small number of particles, the overall vibration can be driven by the telescopic motor, ensuring a stable cooling effect.

[0017] 2. This application addresses the extended problems of uneven static airflow coverage and dead zones in particle cooling processes by setting up a reciprocating airflow mechanism. Specifically, the cooling fan at the bottom of the inclined frame reciprocates through a drive motor and an incomplete gear structure, forming a "universal airflow" effect in conjunction with the rotation of the servo motor. When the drive motor drives the incomplete gear to intermittently mesh with the linkage gear, the fan swings left and right under the action of the torsion spring, while the servo motor synchronously adjusts the rotation angle of the fan, expanding the cold air coverage from a single direction to a three-dimensional space. This dynamic airflow mode ensures that all contact surfaces of the granules are evenly blown by cold air during the rolling process of the inclined frame, avoiding insufficient local heat exchange caused by a fixed airflow direction. At the same time, the oscillating airflow can further disperse the gaps between particles, forming a dual heat dissipation mechanism of mechanical dispersion and airflow disturbance in conjunction with the vibration structure.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Please see Figure 1-6 The present invention provides the following technical solution:

[0027] A cooling device for biomass pellet processing includes a vertical air cooler 1, a cold air inlet 2 fixedly connected to the top of the vertical air cooler 1, a vibrating screen dispersing mechanism 3 movably connected to the inner and rear sides of the vertical air cooler 1, a supporting base plate 4 movably connected to the bottom of the vibrating screen dispersing mechanism 3, and a reciprocating air sweeping mechanism 5 movably connected to the inner side of the vertical air cooler 1.

[0028] The vibrating screen dispersing mechanism 3 includes an inclined frame 31 movably connected to the inside of the vertical air-conditioned cabinet 1. A screen 32 is fixedly connected to the top of the inclined frame 31. A waste drawer 33 is slidably connected to the inside of the inclined frame 31. A feed plate 34 is fixedly connected to the outside of the inclined frame 31. Telescopic columns 35 are fixedly connected to the bottom of both the inclined frame 31 and the feed plate 34. A support rod 36 is fixedly connected to the bottom of the telescopic column 35. A first compression spring 37 is fixedly connected to the inside of the telescopic column 35. The support rod 36 is fixedly connected to the inside of the vertical air-conditioned cabinet 1. Vibration components 38 are movably connected to the bottom and rear of the vertical air-conditioned cabinet 1.

[0029] In this embodiment: When performing biomass pellet cooling, the magnetic door 8 on the front of the vertical cooling cabinet 1 is first closed, so that the interior of the vertical cooling cabinet 1 is basically sealed except for the feed port 6 and the discharge port 7. Then, the air supply pipe for conveying cold air is connected to the inside of the cold air supply port 2 at the top, and low-temperature air is injected into the vertical cooling cabinet 1 to create a low-temperature environment inside. After that, the pellets are poured into the interior of the vertical cooling cabinet 1 through the feed port 6 at the top. In the vertical cooling cabinet 1, instead of the traditional unidirectional cooling path and stacking and stirring cooling path, a four-group square cooling system is used. The segmented cooling path, consisting of two opposing inclined frames 31 and their outer feed plates 34, allows granular material to initially reach the higher point of the inclined frames 31 when entering the vertical air-cooled cabinet 1 or being discharged through the opening of the feed plate 34. Then, using the inertia and gravity of its descent, it rolls towards the next feed plate 34 until it is collected at the discharge port 7. This significantly extends the residence time of the granular material during the cooling process. The inclined frames 31 and feed plates 34 are not fixed inside the vertical air-cooled cabinet 1, but are supported by a fixed structure 36 and 34 inside the vertical air-cooled cabinet 1. The top of the inclined frame 31 is supported by an elastic structure consisting of a telescopic column 35 and a first compression spring 37 on its inner side. Furthermore, a screen 32 is installed on the top of the inclined frame 31, and a waste drawer is located inside the screen 32. Therefore, when granular material is poured or its path is exchanged between different feed plates 34, it will generate varying degrees of impact on the surface of the inclined frame 31. This causes the inclined frame 31 and the feed plates 34 to press downwards against the telescopic column 35 and the first compression spring 37 on its inner side, storing elastic potential energy. The elastic potential energy then rebounds, causing the entire inclined frame 31 and its screen 32 to vibrate. This serves two purposes. The purpose is twofold: firstly, to keep the whole structure in a vibrating state, extend the residence time of the granules in segments, and then use vibration to disperse the granules and prevent them from piling up; secondly, to screen out and collect granules that do not meet the processing requirements and internal impurities; and thirdly, to prevent the situation where vibration cannot be generated or the vibration effect is poor when there are few granules, the vibration component 38 uses the inertia generated by the vibration of the whole vertical air-cooled cabinet 1 to drive the inclined frame 31 and the feed plate 34 inside, so that the telescopic column 35 between them and the support rod 36 can play its role, thereby achieving multiple effects such as dispersed cooling.

[0030] Specifically, such as Figure 1 , Figure 2 , Figure 6 As shown, the reciprocating air sweeping mechanism 5 includes a servo motor 51 fixedly connected to both sides of the vertical air-cooled cabinet 1. The output end of the servo motor 51 is fixedly connected to a rotating bracket 52, and a cooling fan 53 is rotatably connected to the inner side of the rotating bracket 52.

[0031] Specifically, such as Figure 1 , Figure 2 , Figure 6 As shown, an extension shaft 54 ​​is fixedly connected to the front side of the cooling fan 53. The extension shaft 54 ​​is rotatably connected to the front side of the rotating bracket 52. A linkage gear 55 is fixedly connected to the front side of the extension shaft 54. A torsion spring 56 is fixedly connected to the rear side of the linkage gear 55. The torsion spring 56 is fixedly connected to the front side of the rotating bracket 52.

[0032] Specifically, such as Figure 1 , Figure 2 , Figure 6 As shown, a drive motor 57 is fixedly connected to the front side of the rotating bracket 52, and an incomplete tooth 58 is fixedly connected to the output end of the drive motor 57. The incomplete tooth 58 is movably connected to the outside of the linkage gear 55.

[0033] In this embodiment: cooling fans 53 are installed on the top of each inclined frame 31, and these cooling fans 53 are supported by rotating brackets 52. When the granular material is conveyed, the cooling fans 53 will blow air. To make the airflow more uniform, the drive motor 57 on the outside of the rotating bracket 52 needs to be activated. The incomplete gear 58 at the output end of the drive motor 57 will rotate. When the toothed part of the incomplete gear 58 meshes with the linkage gear 55, it will drive the linkage gear 55 to rotate. The linkage gear 55 will then drive the extension shaft 54 ​​of the cooling fan 53 to rotate, causing the cooling fan 53 to swing to one side. When the incomplete tooth 58 rotates to the toothless part, it separates from the linkage gear 55. At this time, the elastic potential energy stored in the torsion spring 56 on the outside of the extension shaft 54 ​​during the previous rotation of the linkage gear 55 will be released, driving the linkage gear 55 to rotate back. The cooling fan 53 will also swing back and forth. In this way, the cooling fan 53 achieves back and forth swing. In addition, the rotating bracket 52 is mounted on the output end of the servo motor 51. When the servo motor 51 is started, in conjunction with the above-mentioned actions, the cooling fan 53 will present a state similar to universal air sweeping, thereby uniformly cooling the conveyed granular material.

[0034] Specifically, such as Figure 3 , Figure 5 As shown, the vibration assembly 38 includes a multi-section telescopic rod cylinder 38a fixedly connected to the bottom of the vertical air-conditioning cabinet 1. The multi-section telescopic rod cylinder 38a is fixedly connected to the top of the front side of the support base plate 4. A support slide rail 38b is fixedly connected to the rear side of the top of the support base plate 4. The vertical air-conditioning cabinet 1 is slidably connected to the front side of the support slide rail 38b.

[0035] Specifically, such as Figure 3 , Figure 5As shown, a second compression spring 38c is fixedly connected to the inner side of the multi-section telescopic cylinder 38a, a contact plate 38d is fixedly connected to the rear side of the vertical air-conditioning cabinet 1, a telescopic motor 38e is fixedly connected to the top of the support slide rail 38b, and an impact block 38f is fixedly connected to the output end of the telescopic motor 38e. The impact block 38f is located on the top of the contact plate 38d.

[0036] In this embodiment, the vertical air-conditioning unit 1 and the supporting base plate 4 are not directly and rigidly connected, but are supported in two ways: one is a multi-section telescopic cylinder 38a with a built-in second compression spring 38c, and the other is a supporting guide rail slidably connected to the rear side of the supporting base plate 4. Under normal conditions, the vertical air-conditioning unit 1 remains upright. When vibration is required, the telescopic motor 38e on the rear side of the supporting guide rail is activated, and the impact block 38f at the motor output end will extend and retract back and forth, continuously impacting the rear side of the vertical air-conditioning unit 1. When the contact plate 38d is subjected to force, it will cause the entire vertical air-conditioning cabinet 1 to slide downward slightly, pressing the multi-section nested telescopic cylinder at its bottom, causing it to retract section by section. At the same time, it compresses the second compression spring 38c to store elastic potential energy. When the impact stops, the elastic potential energy is released, causing the vertical air-conditioning cabinet 1 to vibrate. Using the inertia generated by the vibration, it drives the inclined frame 31 and the feed plate 34 inside, causing the telescopic column 35 between the feed plate 34 and the support rod 36 to act, thereby achieving multiple effects such as distributed cooling.

[0037] Specifically, such as Figure 1 , Figure 2 As shown, the top of the vertical air-conditioned cabinet 1 is fixedly connected to a feeding port 6, and the bottom of the vertical air-conditioned cabinet 1 is fixedly connected to a discharging port 7.

[0038] Specifically, such as Figure 1 , Figure 2 As shown, the front of the vertical air-conditioned cabinet 1 is rotatably connected to a magnetic door 8.

[0039] In this embodiment: material is fed and collected through the feeding port 6 and the discharging port 7 respectively, and the waste drawer 33 can also be limited when the magnetic door 8 is opened and the impurities inside the waste drawer 33 are cleaned.

[0040] Working principle: Before the biomass pellet cooling operation, the magnetic door 8 on the front of the vertical cooling cabinet 1 is closed, making the interior of the vertical cooling cabinet 1 nearly sealed except for the feeding port 6 and the discharge port 7. Then, by connecting the cold air supply pipe to the inside of the cold air supply port 2 at the top, lower-temperature air is injected into the vertical cooling cabinet 1, creating a lower internal temperature. The pellets are then poured into the interior of the vertical cooling cabinet 1 through the feeding port 6 at the top. Inside the vertical cooling cabinet 1, the traditional unidirectional cooling path and stacking mixing cooling path are replaced by a segmented cooling path composed of four sets of inclined frames 31 in opposite directions and their outer discharge plates 34. The pellets enter the vertical cooling cabinet 1 or through the opening of the discharge plates 34. During feeding, the material is positioned at the higher point of the inclined frame 31 and rolls down to the feeding plate 34 using its falling inertia and gravity until it enters the discharge port 7 for collection. This significantly extends the residence time of the cooling transfer of the granular material. Furthermore, the inclined frame 31 and the feeding plate 34 are not fixedly connected to the interior of the vertical air-cooled cabinet 1, but are supported by a fixed structural support rod 36 inside the vertical air-cooled cabinet 1, and an elastic structure consisting of a telescopic column 35 and a first compression spring 37 on its inner side. Additionally, a screen 32 is installed at the top of the inclined frame 31, with a waste drawer on its inner side. Therefore, during the pouring and feeding process, and when the granular material changes path from the feeding plate 34, it will cause varying degrees of impact on the surface of the inclined frame 31, resulting in the inclined frame 31 and the feeding plate 34 being cooled and cooled. The plate 34 downwards compresses the telescopic column 35 and its inner first compression spring 37 to varying degrees, causing them to generate elastic potential energy and rebound, thereby driving the overall inclined frame 31 and its screen plate to vibrate. On the one hand, the core objective is to keep the whole in a vibrating state through this method, thereby extending the residence time in segments and dispersing the contact through vibration to avoid stacking. On the other hand, it can also remove and collect particles that do not meet the processing requirements and their internal impurities. In order to prevent the situation where there are too few particles to generate vibration or the vibration link is poor, the vertical air-cooled cabinet and the supporting base plate 4 are not rigidly connected, but are respectively connected by a multi-section telescopic cylinder 38a with a built-in second compression spring 38c and a support slidably connected to the rear side of the supporting base plate 4. The internal support rail provides support and maintains a normal vertical position under normal conditions. When vibration is required, the telescopic motor 38e at the rear of the support rail is activated, causing the impact block 38f at the output end of the telescopic motor 38e to reciprocate in extending and retracting. This reciprocating impact applies to the contact plate 38d located at the rear of the vertical air-cooled cabinet 1. After the contact plate 38d is subjected to force, it causes the entire vertical air-cooled cabinet 1 to slide downwards slightly, pressing the multi-section nested telescopic cylinder at its bottom, causing it to retract section by section and releasing elastic potential energy. This vibration of the entire vertical air-cooled cabinet 1 generates inertia, which drives the internal inclined frame 31 and the feed plate 34 to act on the telescopic column 35 between them and the support rod 36, thereby producing various effects such as dispersed cooling. Furthermore, to further ensure the cooling effect...A cooling fan 53, supported by a rotating bracket 52, is installed at the top of each inclined frame 31. During the transfer of granular material, air is supplied. To ensure uniform airflow, a drive motor 57 on the outside of the rotating bracket 52 is activated, causing the incomplete gear 58 at the output end of the drive motor 57 to rotate. When the toothed surface of the incomplete gear 58 contacts the linkage gear 55, they mesh and rotate, causing the extension shaft 54 ​​of the cooling fan 53 to rotate and swing to one side via the linkage gear 55. When the incomplete gear 58 rotates to the toothless surface, the meshing is disengaged, allowing the linkage gear 55 to act on the extension shaft 54 ​​during its previous rotation. The elastic potential energy of the outer torsion spring 56 is released, causing the linkage gear 55 to rotate, thereby driving the cooling fan 53 to swing in the opposite direction and realize the reciprocating swing of the cooling fan 53. The rotating bracket 52 is located at the output end of the servo motor 51. In this state, the servo motor 51 starts, and in conjunction with the above linkage, the cooling fan 53 performs a near-omnidirectional sweeping motion, thus uniformly delivering and cooling the pellet material. In summary, this optimizes the cooling for biomass pellet processing. Furthermore, the magnetic door 8 can be opened to clean impurities from the waste drawer 33, and when the magnetic door 8 is closed, it can also limit the movement of the waste drawer 33.

[0041] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
