Description

Technical Field

[0001] This utility model relates to the field of soil conditioning technology, and more specifically, to a granulation device for a biochar-based soil conditioner. Background Technology

[0002] A biochar-based soil conditioner granulation device is a specialized piece of equipment designed to process biochar into granular products with a certain shape, strength, and size after mixing it with other soil conditioner ingredients. Its core function is to solve the molding problem caused by the lightweight, porous, and easily agglomerated characteristics of biochar through the process of mixing, kneading, extrusion molding, and pelletizing, so as to produce granular conditioners that are easy to store, transport, and apply.

[0003] A search revealed that Chinese patent CN222287226U discloses a "granulation device for a biochar-based soil conditioner," which includes a granulation box. An inlet pipe is fixedly installed on the upper surface of the granulation box, with its lower end penetrating into the interior of the granulation box. A matching closing plate is provided at the upper opening of the inlet pipe. The inlet pipe is hinged to the left end of the closing plate. A fixing mechanism is provided on the closing plate to fix the inlet pipe to the closing plate. The fixing mechanism includes a pull switch, which can fix the inlet pipe to the closing plate by inserting a trapezoidal snap-fit ​​plate into a snap-fit ​​groove, thus closing the upper opening of the inlet pipe. This confines the large amount of dust generated during the granulation process within the granulation box, preventing dust from escaping and being inhaled by workers, thus enhancing the device's sealing performance and improving worker safety. However, the following drawbacks still exist:

[0004] (1) If the distance between the scraper and the extrusion plate cannot be adjusted, the particle quality will decrease, the production efficiency will be reduced and the applicability will be limited because it cannot adapt to the material characteristics and production needs.

[0005] After granulation, the soil undergoes a direct hard collision with the particles, and under high shear force, the particles are prone to breakage. Therefore, a granulation device for biochar-based soil conditioners is proposed. Utility Model Content

[0006] The purpose of this invention is to address the problem that if the distance between the scraper and the extrusion plate cannot be adjusted, it will lead to a decrease in particle quality, a reduction in production efficiency, and a limitation in applicability due to the inability to adapt to material characteristics and production needs.

[0007] To achieve the above-mentioned objectives, this utility model provides the following technical solution:

[0008] The present invention is as follows: a granulation device for biochar-based soil conditioner, comprising a tank, a feeding port on the circumferential surface of the tank, a discharge port at the bottom of the tank, a fixed end of a servo motor at the top of the tank, a drive rod fixedly mounted on the output end of the servo motor, a docking frame fixedly mounted on the circumferential surface of the drive rod, and an adjustment device, comprising a drive button fixedly mounted on the bottom of the docking frame, a limit block fixedly mounted on the circumferential surface of the drive button, a sliding sleeve slidably mounted on the outer wall of the limit block, a fixed rod fixedly mounted on the circumferential surface of the sliding sleeve, a scraper rotatably mounted on the surface of the fixed rod, a spring hinge between the scraper and the fixed rod, a groove being formed at the bottom of the sliding sleeve, and the scraper being connected to the fixed rod via the spring hinge, generating a buffer displacement upon contact with the granules.

[0009] As a preferred technical solution of this utility model, the surface of the docking frame is provided with an extrusion roller, the inner wall of the tank is provided with an extrusion plate, and the extrusion roller is in contact with the extrusion plate.

[0010] As a preferred technical solution of this utility model, the number of the extrusion rollers is set to two, and they are symmetrical to each other along the vertical central axis of the docking frame. The number of the fixing rods and scrapers is set to three, and they are arranged in a circular array along the center of the sliding sleeve.

[0011] As a preferred technical solution of this utility model, a threaded rod is fixedly installed at the bottom of the drive button, and a lifting ring is threaded on the circumferential surface of the threaded rod. A sleeve is fitted onto the circumferential surface of the lifting ring. By rotating the lifting ring, the lifting ring moves downward under the setting of the threaded rod. The movement of the lifting ring drives the sleeve to move. The movement of the sleeve causes the sliding sleeve to move downward, and the sliding groove is in continuous contact with the sleeve. The movement of the sliding sleeve drives the scraper to move, thereby increasing the cutting distance of the raw material.

[0012] As a preferred technical solution of this utility model, a curing device is provided below the drive button. The curing device includes a connecting frame, which is fixedly installed on the circumferential surface of the threaded rod. A fixing button is fixedly installed on the circumferential surface of the connecting frame.

[0013] As a preferred technical solution of this utility model, a connecting rod is rotatably installed on the inner wall of the fixed button, a torsion spring is provided between the connecting rod and the fixed button, and a flexible blade is fixedly installed on the inner wall of the connecting rod. The number of the connecting rod and the flexible blade is set to two, and they are symmetrical to each other along the vertical central axis of the fixed button. The flexible blade itself reduces the shearing force, and the connecting rod can be rotated to compress the torsion spring by force. The contact distance with the particles is adaptively controlled by the torsion spring.

[0014] As a preferred technical solution of this utility model, the outer wall of the tank is provided with a heating component, and the inner wall of the tank is provided with a spray nozzle. The number of spray nozzles is set to several and arranged in a circular array along the center circumference of the tank. The heating component heats the bottom of the inner wall of the tank. At this time, the rotation of the threaded rod drives the connecting frame to rotate, the rotation of the connecting frame drives the fixing button to rotate, and the rotation of the fixing button causes the connecting rods on both sides to rotate. At this time, the extruded particles fall downward by gravity. Adhesive is sprayed through the spray nozzles. Then, the rotation of the connecting rod drives the flexible blade to stir and mix the extruded particles.

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

[0016] 1. Through the set adjustment device, after the raw material is fed into the feeding port, it is crushed by two extrusion rollers, so that the raw material gradually forms a uniform agglomerate. Then, it is gradually squeezed into the extrusion plate and extruded into a long strip. At this time, the long strip of raw material is cut by a scraper, so that the raw material is in the form of uniformly sized granules. Traditional rigid cutters are prone to causing the edges of the granules to break. However, the scraper is connected to the fixed rod by a spring hinge, which generates a buffer displacement when it contacts the granules, thereby reducing the impact load and reducing the granule breakage rate. Through the adjustment device, the cutting distance of the raw material can be adjusted in real time, so that granules with different aspect ratios can be produced on the same set of equipment to meet diverse size requirements.

[0017] 2. Through the set curing device, the inner wall bottom of the tank is heated by the heating component, and the adhesive is sprayed through the spray nozzle. Then, the connecting rod rotates to drive the flexible blades to stir and mix the extruded particles. After the particles are dried, the adhesive is sprayed to form a protective film, which improves the compressive strength of the particles and reduces breakage during transportation and application. When there are many particles, the flexible material of the flexible blades reduces the shear force, and the connecting rod can be rotated to compress the torsion spring through the force. The torsion spring adaptively controls the contact distance with the particles to prevent hard collisions with the particles that would cause them to break. Attached Figure Description

All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without inventive effort are within the scope of protection of this utility model.

[0026] It should be noted that, unless otherwise specified, the embodiments and features and technical solutions in the present invention can be combined with each other.

[0027] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0028] like Figures 1-4As shown, this embodiment proposes a biochar-based soil conditioner granulation device, including a tank 1. A feeding port 2 is provided on the circumferential surface of the tank 1, and a discharge port is provided at the bottom of the tank 1. A fixed end of a servo motor 3 is provided on the top of the tank 1. A drive rod 4 is fixedly installed on the output end of the servo motor 3. A docking frame 5 is fixedly installed on the circumferential surface of the drive rod 4. The device also includes an adjustment device 8, which includes a drive button 80. The drive button 80 is fixedly installed at the bottom of the docking frame 5. A limit block 81 is fixedly installed on the circumferential surface of the drive button 80. A sliding sleeve 82 is slidably installed on the outer wall of the limit block 81. A fixed rod 83 is fixedly installed on the circumferential surface of the sliding sleeve 82. A scraper 84 is rotatably installed on the surface of the fixed rod 83. A spring hinge is provided between the scraper 84 and the fixed rod 83. A groove is provided at the bottom of the sliding sleeve 82. Traditional rigid cutters are prone to causing the particle edges to break. However, the scraper 84 is connected to the fixed rod 83 through the spring hinge. When it contacts the particle, it generates a buffer displacement, which reduces the impact load and lowers the particle breakage rate.

[0029] like Figure 2 As shown, in a preferred embodiment, based on the above method, the surface of the docking frame 5 is further provided with an extrusion roller 6, and the inner wall of the tank 1 is provided with an extrusion plate 7. The extrusion roller 6 contacts the extrusion plate 7, and the raw material is crushed by the two extrusion rollers 6, so that the raw material gradually forms a uniform clump, and then is gradually squeezed into the extrusion plate 7 by the extrusion roller 6. The raw material through the inner wall of the extrusion plate 7 increases continuously, so that the clump gradually grows into a strip and is extruded.

[0030] like Figure 3 and Figure 4 As shown, in a preferred embodiment, based on the above method, the number of extrusion rollers 6 is further set to two, and they are symmetrical to each other along the vertical central axis of the docking frame 5. The number of fixing rods 83 and scrapers 84 is set to three, and they are arranged in a circular array along the center of the sliding sleeve 82.

[0031] like Figure 4 As shown, in a preferred embodiment, based on the above method, a threaded rod 85 is further fixedly installed at the bottom of the drive button 80, a lifting ring 86 is threaded on the circumferential surface of the threaded rod 85, and a sleeve bracket 87 is sleeved on the circumferential surface of the lifting ring 86, so that the cutting distance of the raw material is increased, that is, the required cutting length is adjusted, so that particles with different length-to-diameter ratios can be produced on the same set of equipment to meet diverse size requirements.

[0032] like Figure 4 As shown, in a preferred embodiment, based on the above method, a curing device 9 is further provided below the drive button 80. The curing device 9 includes a connecting frame 90, which is fixedly installed on the circumferential surface of the threaded rod 85. A fixing button 91 is fixedly installed on the circumferential surface of the connecting frame 90.

[0033] like Figures 2-4 As shown, in a preferred embodiment, based on the above method, a connecting rod 92 is rotatably mounted on the inner wall of the fixed button 91, a torsion spring is provided between the connecting rod 92 and the fixed button 91, and a flexible blade 93 is fixedly mounted on the inner wall of the connecting rod 92. The number of connecting rods 92 and flexible blades 93 is set to two, and they are symmetrical to each other along the vertical central axis of the fixed button 91.

[0034] like Figure 5 As shown, in a preferred embodiment, based on the above method, the outer wall of the tank 1 is further provided with a heating component 94, and the inner wall of the tank 1 is provided with a spray nozzle 95. The number of spray nozzles 95 is set to several and arranged in a circular array along the center circumference of the tank 1. The heating component 94 heats the bottom of the inner wall of the tank 1, and the adhesive is sprayed through the spray nozzle 95. Then, the connecting rod 92 rotates to drive the flexible paddle 93 to stir and mix the extruded particles. After the particles are dried, the adhesive is sprayed to form a protective film and improve the compressive strength of the particles.

[0035] Specifically, in use, the biochar-based soil conditioner granulation device works as follows: the output of the servo motor 3 drives the drive rod 4 to rotate, which in turn drives the docking frame 5 to rotate, and the docking frame 5 to move the extrusion roller 6. Raw materials are fed into the feeding port 2. After entering the tank 1, the raw materials are crushed by the two extrusion rollers 6, gradually forming a uniform agglomerate. This agglomerate is then gradually squeezed into the extrusion plate 7 by the extrusion rollers 6. As the raw material accumulates on the inner wall of the extrusion plate 7, the agglomerate gradually becomes a long strip for extrusion. Simultaneously, the rotation of the docking frame 5 drives the drive knob 80 to rotate, which in turn drives the sliding sleeve 82 to rotate, which in turn drives the fixed rod 83 to rotate, and the fixed rod 83 to move the scraper 84, thus extruding the long strip. The raw material is cut into uniformly sized granules. Traditional rigid cutters are prone to causing the edges of the granules to break. However, the scraper 84 is connected to the fixed rod 83 by a spring hinge. When it contacts the granules, it generates a buffer displacement, which reduces the impact load and the breakage rate of the granules. When it is necessary to adjust the cutting length, the lifting ring 86 is rotated. With the setting of the threaded rod 85, the lifting ring 86 moves downward. The movement of the lifting ring 86 drives the sleeve frame 87 to move. The movement of the sleeve frame 87 causes the sliding sleeve 82 to move downward, and the slide groove is in continuous contact with the sleeve frame 87. The movement of the sliding sleeve 82 drives the scraper 84 to move, which increases the cutting distance of the raw material, that is, adjusts the required cutting length. This allows the same set of equipment to produce granules with different length-to-diameter ratios to meet diverse size requirements.

[0036] The heating component 94 heats the bottom of the inner wall of the tank 1. At this time, the threaded rod 85 rotates, driving the connecting frame 90 to rotate. The rotation of the connecting frame 90 drives the fixing button 91 to rotate, which in turn causes the connecting rods 92 on both sides to rotate. The extruded particles fall downwards under gravity. Adhesive is then sprayed through the spray nozzle 95. Subsequently, the rotation of the connecting rod 92 drives the flexible paddle 93 to stir and mix the extruded particles. After the particles are dried, the adhesive is sprayed to form a protective film, which improves the compressive strength of the particles and reduces breakage during transportation and application. When there are many particles, the flexible material of the flexible paddle 93 reduces the shear force. The force can also cause the connecting rod 92 to rotate and compress the torsion spring. The torsion spring adaptively controls the contact distance with the particles to prevent hard collisions that could cause particle breakage.

[0037] All technical features in this embodiment can be freely combined according to actual needs.

[0038] The above embodiments are preferred implementations of this utility model. In addition, this utility model can also be implemented in other ways. Any obvious substitutions without departing from the concept of this technical solution are within the protection scope of this utility model.
