Description

Technical Field

[0001] This invention relates to the field of cooling chamber technology, and more specifically to a biomass pellet cooling chamber device. Background Technology

[0002] Existing biomass pellet cooling chambers have significant technical shortcomings in practical applications, failing to efficiently utilize air to target and cool localized or all high-temperature areas of the biomass pellets within the chamber.

[0003] Most cooling chambers on the market currently use either overall natural ventilation or single forced ventilation modes, lacking an adaptive temperature control structure and unable to flexibly adjust the airflow volume according to the temperature distribution differences of particles inside the chamber.

[0004] When localized high temperatures occur in the pellets, overall ventilation cannot concentrate air to precisely cool the high-temperature areas, resulting in low air utilization efficiency and difficulty in quickly dissipating localized high temperatures. When the pellets are in a high-temperature state, the ventilation intensity cannot adaptively match, easily leading to incomplete cooling, air waste, or increased energy consumption. This deficiency not only affects the cooling efficiency and uniformity of biomass pellets but may also affect pellet quality due to untimely cooling, failing to meet the high-efficiency and energy-saving cooling requirements of large-scale production.

[0029] This invention utilizes shape memory alloy springs that can flexibly respond to the local or overall high temperature state of biomass particles within the cooling chamber. The shape memory alloy springs in the corresponding areas contract due to heat transferred through the first or second heat-conducting box, causing the corresponding air-cutting pipe, first air-distributing pipe, and second air-distributing pipe to separate from the sealing head and second air-distributing pipe. The flowing air exits through these gaps and then flows back through the return pipe to the first and second ventilators, ultimately exiting from the first and second ventilators. This directly acts on the high-temperature biomass particles, quickly removing heat from the localized high-temperature areas, achieving precise and enhanced cooling. The air carrying heat is finally discharged through the exhaust port, significantly improving cooling efficiency and uniformity. This temperature-sensing-based automatic adjustment cooling structure achieves precise matching of cooling intensity. Attached Figure Description

Rather, these embodiments are provided so that this invention will be thorough and complete, and will fully convey the scope of the invention to those skilled in the art.

[0045] like Figures 1 to 12 As shown, an embodiment of the present invention provides a biomass pellet cooling chamber device, including: a frame 1 and a cooling chamber 2 disposed on the frame 1, a discharge hopper 3 fixed inside the frame 1, and further including: a chamber cover 4, bolted to the top of the cooling chamber 2; a feeder 5, fixed to the top of the chamber cover 4; a bulk material component 6, fixed inside the cooling chamber 2; an air-cooling component 7, fixed inside the cooling chamber 2; a discharge component 8, rotatably disposed on the frame 1; a surrounding plate 9, fixed to the inside of the frame 1; a vent plate 10, fixed to the surrounding plate 9; a maintenance door 11, fixed to the cooling chamber 2; a handle 12, fixed to the maintenance door 11; a first inspection window 13, fixed to the cooling chamber 2; and a second inspection window 14, fixed to the cooling chamber 2.

Five second vent cylinders 705 are arranged at equal intervals; a first heat-conducting box 706 is fixed above the first vent cylinder 704 and at both ends of the second vent cylinders 705; a second heat-conducting box 707 is fixed above the second vent cylinders 705; a mounting ring 708 is fixed inside the first vent cylinder 704 and the second vent cylinder 705; a first air distribution pipe 709 is fixed to the air supply pipe 703, fixed inside the mounting ring 708, and located inside the first vent cylinder 704; a cutting-off pipe 7010 is slidably inserted into the first heat-conducting box. 706 is a top plate; a limiting ring 7011 is fixed to the air-cutting pipe 7010 and located at the bottom of the first heat-conducting box 706; a second air-distributing pipe 7012 is fixed inside the mounting ring 708 and located inside the second vent 705; a gradually expanding groove 7013 is opened at the upper port of the first air-distributing pipe 709 and at the upper and lower ends of the second air-distributing pipe 7012; a tapering opening 7014 is opened at the upper and lower ends of the air-cutting pipe 7010; a sealing rubber layer 7015 is fixed to the tapering opening 7014; and a sealing head 7016 is a sliding... The uppermost heat-conducting box 707 is dynamically installed; the spring plate 7017 is fixed above the closed head 7016 and located at the bottom of the second heat-conducting box 707; the limiting post 7018 is fixed at the top of the second heat-conducting box 707; the shape memory alloy spring 7019 is fixed at one end to the limiting ring 7011 and the spring plate 7017, and the other end is fixed at the top of the first heat-conducting box 706 and the second heat-conducting box 707; the return pipe 7020 is fixed below the first heat-conducting box 706 and the second heat-conducting box 707.

[0048] The air-cooled component 7 also includes: a mounting plate 7021, fixed to the four corners of the frame 1 and the enclosure 9; a mounting groove 7022, formed within the mounting plate 7021; an air supply duct 7023, formed on the mounting plate 7021 and the enclosure 9; a motor 7024, fixed within the mounting groove 7022; an impeller 7025, fixed to the output end of the motor 7024 and located within the mounting groove 7022; and a ventilation duct 7026, one end of which is fixed to the enclosure 9. The air supply slot 7023 of plate 9 is fixed at one end and the air collection box 702 at the other end; the connecting rod 7027 is fixed at one end to the surrounding plate 9 and the air collection box 702 at the other end; the auxiliary support rod 7028 is fixed at one end to the ventilation pipe 7026 and the connecting rod 7027 and the other end to the support plate 701; the air inlet pipe 7029 is fixed below the mounting plate 7021; the air filter 7030 is fixed below the air inlet pipe 7029.

[0049] Specifically, the air-cooled component 7 achieves precise and enhanced cooling through the coordinated operation of multiple components. The support plate 701 provides stable support for the air collection box 702 and each air vent. The mounting ring 708 positions the first air distribution pipe 709 and the second air distribution pipe 7012. The sealing rubber layer 7015 ensures the sealing performance when the air cutting pipe 7010 is connected to the first air distribution pipe 709 and the second air distribution pipe 7012. The expanding groove 7013 and the contracting opening 7014 facilitate rapid airflow. The shape memory alloy spring 7019 can contract and expand according to temperature changes. The air cutting pipe 7010 and the sealing head 7016 are moved to realize the automatic adjustment of the air path; the motor 7024 drives the impeller 7025 to draw the air filtered by the air filter 7030, and sends it into the air collection box 702 through the air supply slot 7023 and the ventilation pipe 7026, and then delivers it to the air vent through the air supply pipe 703, the air distribution pipe, etc., to achieve targeted cooling. The connecting rod 7027 and the auxiliary support rod 7028 ensure the stability of the air path structure, and the limiting post 7018 limits the movement of the spring plate 7017 to avoid damage to the components.

[0050] In another preferred embodiment of the present invention, the bulk material component 6 includes: a motor base 601 fixed on the cooling chamber 2; a drive motor 602 fixed on the motor base 601; two positioning rods 603, both fixed on the inner wall of the cooling chamber 2; a bulk material box 604, both ends fixed on the positioning rods 603; a drive rod 605, one end fixed on the output end of the drive motor 602, and the other end rotatably inserted into the bulk material box 604; an auxiliary rotating rod 606 rotatably inserted into the bulk material box 604; a bevel gear pair 607, the input bevel gear fixed on the auxiliary rotating rod 606, and the output bevel gear fixed on the auxiliary rotating rod 606; a bulk material main plate 608 fixed below the auxiliary rotating rod 606; a bulk material vertical plate 609 fixed below the bulk material main plate 608; and a cone cover 6010 fixed above the auxiliary rotating rod 606.

[0051] Specifically, the bulk material component 6 drives the bulk material component to operate through the drive structure. The motor base 601 provides a stable mounting foundation for the drive motor 602. The positioning rod 603 fixes the bulk material box 604 to ensure the stability of the overall structure. The drive motor 602 drives the drive rod 605 to rotate, and transmits power through the bevel gear 607 to drive the auxiliary rotating rod 606 to rotate. The auxiliary rotating rod 606 simultaneously drives the cone cover 6010, the bulk material main plate 608, and the bulk material vertical plate 609 to rotate. The cone cover 6010 evenly disperses the particles falling from the feeder 5, and the bulk material vertical plate 609 combs the particles in the cooling chamber 2 to avoid accumulation and ensure uniform cooling.

[0052] In another preferred embodiment of the present invention, the unloading component 8 includes: an unloading shaft 801, rotatably mounted on the frame 1 and the surrounding plate 9; an unloading plate 802, fixed on the unloading shaft 801; a turntable 803, fixed on one end of the unloading shaft 801 extending out of the frame 1; a main swing plate 804, fixed on one end of the unloading shaft 801 extending out of the frame 1; an auxiliary swing plate 805, fixed on one end of the unloading shaft 801 extending out of the frame 1; a linkage plate 806, one end rotatably mounted on the main swing plate 804, and the other end rotatably mounted on the auxiliary swing plate 805; a rotating base plate 807, fixed on the frame 1; a first rotating plate 808, rotatably mounted on the rotating base plate 807; a second rotating plate 809, rotatably mounted below the main swing plate 804; and a hydraulic telescopic rod 8010, the non-telescopic end of which is fixed on the end of the first rotating plate 808 away from the rotating base plate 807, and the telescopic end of which is fixed on the end of the second rotating plate 809 away from the main swing plate 804.

[0053] Specifically, the feeding component 8 achieves precise control of the feeding action through hydraulic drive. The rotating plate 807 provides rotational support for the first rotating plate 808. When the hydraulic telescopic rod 8010 extends or retracts, it drives the second rotating plate 809 to rotate, which in turn drives the main swing plate 804 to swing. The main swing plate 804 drives the auxiliary swing plate 805 to swing synchronously through the linkage plate 806. Both drive the feeding shaft 801 and the turntable 803 to rotate. The rotation of the feeding shaft 801 drives the feeding plate 802 to swing, realizing the opening and closing of the feeding port, thereby controlling the discharge speed and discharge volume of the cooled biomass pellets. The turntable 803 can intuitively reflect the rotation status of the feeding shaft 801, which is convenient for observation and adjustment.

[0054] The biomass pellet cooling chamber is controlled entirely by a central control console. Its core function is to efficiently cool the biomass pellets. It is also equipped with convenient maintenance and observation structures to ensure stable operation. Operators can open the maintenance door 11 through handle 12 to directly access the internal space of the cooling chamber 2 and quickly carry out equipment maintenance. The first inspection window 13 and the second inspection window 14 are both made of glass, allowing operators to observe the status of the biomass pellets and the operation of the equipment inside the cooling chamber 2 in real time and promptly identify any abnormalities. During the cooling process of the biomass pellets, the cooling chamber 2 generates a large amount of heat. This heat is released into the outside air through the exhaust port 15, preventing the internal temperature of the cooling chamber 2 from becoming too high and affecting the cooling effect.

[0055] The biomass pellet cooling process begins with feeding. Biomass pellets smoothly enter the cooling chamber 2 through the feeder 5. At this time, the drive motor 602 is started, and the drive motor 602 drives the drive rod 605 to rotate synchronously. The rotation of the drive rod 605 directly drives the bevel gear pair 607 to rotate. The rotation of the bevel gear pair 607 drives the auxiliary rotating rod 606 to rotate. The auxiliary rotating rod 606 simultaneously drives the bulk material main plate 608 and the cone cover 6010 to rotate. The rotation of the bulk material main plate 608 drives the bulk material vertical plate 609 to rotate rapidly. During the rotation, the bulk material vertical plate 609 evenly combs the biomass pellets in the cooling chamber 2 to prevent pellet accumulation from affecting the cooling uniformity. The rotation of the cone cover 6010 can evenly disperse the biomass pellets falling from the feeder 5, so that the pellets can fully contact the cooling air, laying the foundation for subsequent efficient cooling. The positioning rod 603 plays a fixed support role for the bulk material box 604, ensuring the overall stable operation of the bulk material component.

[0056] Under normal operating conditions, air naturally flows into the gap between the frame 1 and the enclosure 9. After initial buffering, it enters the cooling chamber 2 evenly through the vent plate 10. The air entering the cooling chamber 2 comes into full contact with the high-temperature biomass pellets, quickly absorbing the heat emitted by the biomass pellets. The air carrying the heat is then discharged from the cooling chamber 2 through the exhaust port 15, forming a natural ventilation cooling cycle to achieve initial cooling of the biomass pellets. The vent plate 10 ensures uniform air distribution and avoids uneven cooling caused by poor local air circulation. The enclosure 9 protects and fixes the internal structure of the cooling chamber 2, ensuring a stable air circulation path.

[0057] When the temperature detection system in the cooling chamber 2 detects that the temperature of the biomass pellets is too high and natural ventilation cooling cannot meet the cooling requirements, the equipment will automatically activate the air-cooling component 7 for enhanced cooling. After the motor 7024 is started, the motor 7024 drives the impeller 7025 to rotate at high speed. The impeller 7025 draws in outside air through the air inlet pipe 7029. The air is first filtered by the air filter 7030 to remove dust, impurities, etc., to prevent impurities from entering the cooling chamber 2 and contaminating the biomass pellets or damaging the internal components. The filtered air is sent into the air delivery slots 7023 opened on the mounting plate 7021 and the surrounding plate 9, and then transported to the air collection box 702 through the ventilation pipe 7026. The mounting plate 7021 is fixed at the four corners of the frame 1 and the surrounding plate 9. The mounting slot 7022 provides a stable installation space for the motor 7024 and the impeller 7025. The connecting rod 7027 and the auxiliary support rod 7028 provide fixed support for the air collection box 702 and the ventilation pipe 7026, respectively, to ensure stable air delivery.

[0058] The air in the air collection box 702 is then diverted to the air supply pipe 703 in the support plate 701. The air supply pipe 703 delivers the air to the first air distribution pipe 709. At this time, the first air distribution pipe 709 is connected to the air cutting pipe 7010, and the air cutting pipe 7010 is connected to the second air distribution pipe 7012. The air can flow smoothly between the air pipes. There are four support plates 701, which are fixed at equal angles on the surrounding plate 9 to provide stable support for the air collection box 702 and each air vent. The mounting ring 708 is fixed inside the first air vent 704 and the second air vent 705, and plays a role in positioning and fixing the first air distribution pipe 709 and the second air distribution pipe 7012.

[0059] The high-temperature biomass pellets in the cooling chamber 2 will transfer heat to the first heat-conducting box 706 and the second heat-conducting box 707. The first heat-conducting box 706 is fixed above the first vent 704 and at the upper and lower ends of the second vent 705. The second heat-conducting box 707 is fixed above the second vent 705. Five second vent 705s are arranged at intervals directly above the same first vent 704 to increase the contact area between air and pellets.

[0060] The shape memory alloy springs 7019 inside the first heat-conducting box 706 and the second heat-conducting box 707 will contract under the influence of heat. One end of the shape memory alloy spring 7019 is fixed to the limiting ring 7011 and the spring plate 7017, and the other end is fixed to the inner top of the first heat-conducting box 706 and the second heat-conducting box 707. When contracted, it will pull the limiting ring 7011 or the spring plate 7017 to move upward. The limiting ring 7011 is fixed to the air-cutting pipe 7010 and is located at the bottom of the first heat-conducting box 706. The upward movement of the limiting ring 7011 will cause the air-cutting pipe 7010 to separate from the first air-distribution pipe 709 or the second air-distribution pipe 7012. The spring plate 7017 is fixed. Above the closed head 7016 and located at the bottom of the second heat-conducting box 707, the upward movement of the spring plate 7017 will cause the closed head 7016 to separate from the uppermost second air distribution pipe 7012. The limiting post 7018 is fixed at the top of the second heat-conducting box 707, which can limit the movement of the spring plate 7017 and prevent excessive movement from damaging the components. The upper and lower ends of the air cutting pipe 7010 are provided with tapered openings 7014, and a sealing rubber layer 7015 is fixed on the tapered openings 7014 to ensure sealing performance during docking and prevent air leakage. The upper port of the first air distribution pipe 709 and the upper and lower ends of the second air distribution pipe 7012 are provided with expanding grooves 7013 to facilitate rapid air circulation.

[0061] The shape memory alloy spring 7019 can flexibly respond to the local or overall high temperature state of the biomass particles in the cooling chamber 2. The shape memory alloy spring 7019 in the corresponding area contracts through the heat transferred by the first heat conduction box 706 or the second heat conduction box 707, which drives the corresponding air cutting pipe 7010, the first air distribution pipe 709 and the second air distribution pipe 7012 to separate from the sealing head 7016 and the second air distribution pipe 7012. The flowing air will flow out through the gaps formed by these separations, and then flow through the return pipe 7020 to the first vent 704 and the second vent 705, and finally flow out from the first vent 704 and the second vent 705, directly acting on the high temperature biomass particles, quickly removing the heat from the local high temperature area, and achieving precise and enhanced cooling. The air carrying heat is finally discharged through the exhaust port 15, which greatly improves the cooling efficiency and cooling uniformity. This temperature-sensing-based automatic adjustment cooling structure achieves precise matching of cooling force.

[0062] After cooling, the biomass pellets are discharged in an orderly manner through the feeding component 8. The hydraulic telescopic rod 8010 is activated, and its extension and retraction drive the second rotating plate 809 to rotate. The rotation of the second rotating plate 809 causes the main swing plate 804 to swing back and forth. The main swing plate 804, through the linkage plate 806, drives the auxiliary swing plate 805 to swing synchronously. Both the main swing plate 804 and the auxiliary swing plate 805 are fixed to one end of the feeding shaft 801 extending from the frame 1. Their synchronous swinging drives the feeding shaft 801 and the turntable 803 to rotate. The turntable 803 can visually reflect the rotation status of the feeding shaft 801, facilitating operator observation. The rotation of the feeding shaft 801 causes the feeding plate 802 fixed to it to swing back and forth. The swinging of the feeding plate 802 controls the opening and closing of the feeding port, thereby adjusting the feeding speed and quantity. The rotating plate 807 is fixed on the frame 1, providing rotational support for the first rotating plate 808. The non-telescopic end of the hydraulic telescopic rod 8010 is fixed at the end of the first rotating plate 808 away from the rotating plate 807. The telescopic end of the hydraulic telescopic rod 8010 is fixed at the end of the second rotating plate 809 away from the main swing plate 804. This connection structure can ensure the stable transmission of power of the hydraulic telescopic rod 8010 and ensure the smooth and continuous feeding action. The cooled biomass pellets fall from the feeding plate 802 and enter the discharge hopper 3 fixed inside the frame 1, and then are smoothly discharged from the bottom of the discharge hopper 3, completing the entire cooling and feeding process.

[0063] The above description represents the preferred embodiments of the present invention. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principles of the present invention, and these improvements and modifications should also be considered within the scope of protection of the present invention.
