Abstract
Description
Technical Field
[0001] The invention relates to the technical field of transmission devices, in particular to a gear box heating device for a biological granulator. Background Art
[0002] During the processing of biomass-based pellet fuel, the viscosity of the lubricating oil in the bio-pellet mill varies with temperature. In low-temperature environments or when the bio-pellet mill is first started, the lubricating oil viscosity is higher. High-viscosity lubricating oil has poor fluidity and difficulty quickly reaching the various parts of the gearbox that require lubrication, such as gear meshes and bearings. This results in poor lubrication and increased friction and wear between components. The pellet mill's gearbox is typically heated to reduce the viscosity of the lubricating oil in the gearbox oil tank, thereby reducing resistance during gear rotation and minimizing power loss.
[0003] For a pair of meshing gears, the lubricant distributed radially will maintain a uniform temperature distribution as soon as the gears begin to rotate. However, the lubricant distributed axially, that is, on both sides of the gear plate, will still experience uneven temperature distribution because the rotation of the gears makes it difficult for the surrounding area to be disturbed.
[0004] In view of this, we propose a bio-granulator gearbox heating device to improve the deficiencies in the existing technology. Summary of the Invention
[0005] In response to the technical problems existing in the prior art, the present invention provides a biogranulator gearbox heating device to solve the problem in the above-mentioned background technology that the lubricating oil on both sides of the gear disc is difficult to disturb due to the rotation of the gear disc, resulting in uneven temperature distribution of the lubricating oil on both sides of the gear disc.
[0006] To solve the above-mentioned problems, the technical solution of the present invention is as follows: a biological granulator gearbox heating device, comprising a granulator body, the granulator body comprising at least a granulation box, a pair of crushing rollers arranged side by side being rotatably connected in the granulation box, a gear body being provided at the same end of the two crushing rollers, the two gear bodies being coaxially connected to the corresponding crushing rollers, a gearbox body being provided around the periphery of the two gear bodies, and the gearbox body being fixedly connected to one side of the granulation box;
[0007] The interior of the gearbox body is provided with a heating mechanism and a spoiler mechanism in order from bottom to top, the spoiler mechanism at least comprising an oil tank and a spoiler module, the oil tank is used to store lubricating oil, and the heating mechanism is used to heat the lubricating oil in the oil tank;
[0008] The two gear bodies meshing with each other can stir the inside of the oil tank along their own radial direction. The spoiler module can disturb the flow direction of the lubricating oil flowing along the radial direction of the gear body, so that the lubricating oil flows along the axial direction of the gear body. The spoiler module can separate the oil tank to accelerate the temperature change rate of the lubricating oil inside the oil tank.
[0009] Compared with the prior art, the present invention has the following beneficial effects:
[0010] In the biogranulator gearbox heating device, the two meshing gear bodies can stir the inside of the oil tank along their own radial direction. The spoiler module can disturb the flow direction of the lubricating oil flowing along the radial direction of the gear body, so that the lubricating oil flows along the axial direction of the gear body. The spoiler module can separate the oil tank to accelerate the temperature change rate of the lubricating oil inside the oil tank.
[0011] On the basis of the above technical solution, the present invention can also make the following improvements:
[0012] As a further improvement of the present technical solution, the two gear bodies are arranged side by side along their own radial directions, and the two gear bodies are meshed with each other.
[0013] As a further improvement of this technical solution, the pelletizer body also includes a diesel engine and a pair of drive discs, one of the drive discs is coaxially connected to one of the crushing rollers, and the other drive disc is coaxially connected to the output shaft of the diesel engine, and the periphery of the two drive discs includes a belt.
[0014] The beneficial effect of adopting the above-mentioned improvement scheme is that when the output shaft of the diesel engine drives the coaxial drive disc to rotate, the circumferential motion of the drive disc is transmitted to the belt through friction, causing the belt to move along the peripheral direction of the drive disc. The moving belt and the other drive disc also rely on friction to transmit the movement of the belt to the other drive disc, causing the other drive disc to rotate in the direction of the belt's movement, thereby achieving further transmission of power and transferring the power of the diesel engine from one drive disc to the other. Under the transmission of two mutually meshing gear bodies, the two crushing rollers rotate in opposite directions, and the dead branches and leaves added to the granulation box enter the gap between the two crushing rollers. As the crushing rollers rotate, the dead branches and leaves are subjected to the extrusion, shearing and friction forces of the two crushing roller surfaces. The dead branches and leaves are gradually broken into smaller particles, ultimately achieving the purpose of crushing the dead branches and leaves into particles.
[0015] As a further improvement of the present technical solution, the heating mechanism includes a heating chamber, and electric heating tubes are provided inside the heating chamber. The electric heating tubes are evenly distributed in a staggered manner inside the heating chamber.
[0016] As a further improvement of the present technical solution, the heating chamber is located below the oil tank.
[0017] As a further improvement of the present technical solution, the height of the top of the oil groove is higher than the height of the bottoms of the two gear bodies.
[0018] The beneficial effect of adopting this improved solution is that, due to the relatively small heat capacity of air, both heating and cooling speeds are relatively fast, which enables the system to respond quickly when adjusting the temperature. When the lubricating oil temperature needs to be adjusted, the power of the electric heating tube is adjusted to change the air temperature. The air can quickly transfer heat to the lubricating oil in the oil tank, achieving rapid temperature adjustment and facilitating precise control of the lubricating oil temperature.
[0019] The heated air forms a hot air flow within the heating chamber, flowing in all directions around the oil tank, heating it from all sides. Compared to directly heating the oil tank, this method allows heat to be distributed more evenly across all parts of the tank, resulting in a more uniform temperature for the lubricating oil within the tank and preventing localized overheating or overcooling. Air has excellent thermal diffusivity, and the heated air continuously exchanges heat with the oil tank surface as it flows. Heat quickly diffuses across the surface and is then evenly transferred to the lubricating oil within, further ensuring uniform lubricating oil temperature.
[0020] As a further improvement of the present technical solution, the spoiler module includes a plurality of symmetrically arranged guide plates, and along the radial direction of the gear body, the distance between the guide plates and the gear body gradually decreases.
[0021] As a further improvement of the present technical solution, a plurality of guide holes are provided on each of the guide plates along the axial direction of the gear body.
[0022] As a further improvement of the present technical solution, the plurality of guide plates are used to divide the oil tank into a plurality of heating zones, and the plurality of heating zones are used to accelerate the temperature change rate of the lubricating oil in the oil tank.
[0023] As a further improvement of this technical solution, the guide plate is made of heat-conducting material.
[0024] The beneficial effect of this improved solution lies in that, because the radial spacing of the deflectors gradually decreases along the gear body, the lubricating oil is guided by the deflector's shape as it flows through the deflectors, flowing in the direction dictated by the deflectors. Specifically, the lubricating oil flows radially from locations with greater spacing to locations with less spacing. During this process, the direction of the lubricating oil's flow continuously changes, thereby creating a turbulent flow for the lubricating oil. Through the guidance of the deflectors and the pressure differential, the lubricating oil flows in different directions and velocities within the oil sump, allowing lubricating oil at different locations, temperatures, and properties to be thoroughly mixed. Lubricating oil that might otherwise be temperature-stratified or have uneven composition is more evenly mixed due to the turbulent flow. This turbulent flow increases the contact area and duration between the lubricating oil and the oil sump sidewalls and the surrounding air. This allows the lubricating oil to more quickly transfer heat generated by the gear body's operation to the oil sump sidewalls, where it is then dissipated to the surrounding environment. Furthermore, the enhanced convection allows for more efficient heat exchange between the lubricating oil and the surrounding air, effectively improving heat dissipation efficiency.

[0038] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative efforts shall fall within the scope of protection of the present invention.
[0039] Lubricating oil has high viscosity. High-viscosity lubricating oil has poor fluidity and difficulty quickly reaching the various parts of the gearbox that need lubrication, such as gear meshes and bearings. This results in poor lubrication and increased friction and wear between components. This application adds a heating device to one side of the gearbox to allow the lubricating oil in the gearbox to heat up quickly and evenly.
[0040] See also Figure 1 and Figure 2 As shown, the present embodiment aims to provide a biological granulator gearbox heating device, comprising a granulator body 100, the granulator body 100 comprising at least a granulation box 110, a pair of crushing rollers 120 arranged side by side being rotatably connected in the granulation box 110, a gear body 130 being provided at the same end of the two crushing rollers 120, the two gear bodies 130 being coaxially connected to the corresponding crushing rollers 120, a gearbox body 101 being provided around the periphery of the two gear bodies 130, and the gearbox body 101 being fixedly connected to one side of the granulation box 110;
[0041] The gearbox body 101 is provided with a heating mechanism 200 and a spoiler mechanism 300 in order from bottom to top. The spoiler mechanism 300 includes at least an oil tank 310 and a spoiler module 320. The oil tank 310 is used to store lubricating oil, and the heating mechanism 200 is used to heat the lubricating oil in the oil tank 310.
[0042] The two gear bodies 130 meshing with each other can stir the inside of the oil tank 310 along their own radial direction. The spoiler module 320 can disturb the flow direction of the lubricating oil flowing along the radial direction of the gear body 130, so that the lubricating oil flows along the axial direction of the gear body 130. The spoiler module 320 can separate the oil tank 310 to accelerate the temperature change rate of the lubricating oil inside the oil tank 310.
[0043] Working principle:
[0044] First, the pelletizer body 100 is started, grinding the dead branches and leaves, etc., into granules. Prior to this, the heating mechanism 200 is powered on, heating the lubricating oil in the oil tank 310 above it. The flow disturbance module 320 within the oil tank 310 disrupts the flow of the lubricating oil radially along the gear body 130, redirecting the oil, which previously flowed radially along the gear body 130, to a swirling motion along the gear body 130's axis. Simultaneously, the flow disturbance module 320 divides the oil tank 310 into multiple "small zones," accelerating the temperature change of the lubricating oil within the oil tank 310. It should be noted that the division of the oil tank 310 into multiple "small zones" allows the lubricating oil within the oil tank 310 to quickly heat up to a stable temperature sufficient for normal operation of the gear body 130 during the heating phase. After the pelletizer body 100 completes pelletizing, the multiple "small zones" within the oil tank 310 quickly dissipate the heat.
[0045] In many biogranulation industrial scenarios, especially in cold regions or during low-temperature seasons, biogranulators often operate in low-temperature environments. For example, in northern winter, outdoor temperatures can reach minus 10 degrees Celsius or even lower. Even in indoor workshops, the ambient temperature can be low without proper insulation, which can directly affect the performance of the lubricant in the gearbox.
[0046] like Figure 3 and Figure 4 As shown, the two gear bodies 130 are arranged side by side along their own radial directions, and the two gear bodies 130 are meshed with each other.
[0047] The improvement is that the pelletizer body 100 also includes a diesel engine 140 and a pair of drive discs 150, one of the drive discs 150 is coaxially connected to one of the crushing rollers 120, and the other drive disc 150 is coaxially connected to the output shaft of the diesel engine 140, and the periphery of the two drive discs 150 includes a belt 160.
[0048] The principles involved in the above-mentioned biogranulation process are disclosed below:
[0049] Diesel engine 140 power output principle: Diesel engine 140 is an internal combustion engine. It burns a mixture of diesel and air to generate high-temperature, high-pressure gas, which drives the piston to reciprocate within the cylinder. The connecting rod then converts the piston's reciprocating motion into rotational motion of the crankshaft, thereby outputting power. The rotation of the crankshaft is the power source of the entire system. Its output shaft is coaxially connected to the drive plate 150, transmitting power to the drive plate 150.
[0050] The transmission principle of belt 160: When the output shaft of diesel engine 140 rotates the coaxial drive plate 150, friction exists between the drive plate 150 and belt 160. Because the surface of drive plate 150 is in close contact with belt 160, the circumferential motion of drive plate 150 is transmitted to belt 160 through friction, causing belt 160 to move along the circumference of drive plate 150. This friction-based transmission mechanism transfers power from drive plate 150 to belt 160. Belt 160 is looped around two drive plates 150, forming a circular transmission path. Friction also acts between the moving belt 160 and the other drive plate 150, transmitting its motion to the other drive plate 150, causing it to rotate in the direction of the belt 160's motion. This further transfers power from diesel engine 140 from one drive plate 150 to the other.
[0051] Gear drive principle: A gear body 130 is mounted on the same end of each crushing roller 120, and the two gear bodies 130 mesh with each other. When one of the drive plates 150 rotates the crushing roller 120 coaxially connected to it, the gear body 130 at one end of that crushing roller 120 also rotates. Due to the meshing relationship between the gear bodies 130, the teeth of one gear body 130 mesh with the teeth of the other gear body 130. When the actively rotating gear body 130 rotates, the interaction between the teeth pushes the driven gear body 130 to rotate. Due to the characteristics of gear drive, the two meshing gear bodies 130 rotate in opposite directions, so the two crushing rollers 120 rotate in opposite directions under the action of their respective gear bodies 130.
[0052] Crushing principle of the crushing rollers 120: When the two crushing rollers 120 rotate in opposite directions, the litter added to the pelletizing box 110 enters the gap between the two crushing rollers 120. As the crushing rollers 120 rotate, the litter is subjected to forces such as compression, shearing, and friction on the surfaces of the two crushing rollers 120. The surfaces of the crushing rollers 120 are typically designed with specific patterns or shapes to increase friction and crush the material. Under the combined action of these forces, the litter is gradually broken into smaller particles, ultimately achieving the goal of reducing the litter to pellets.
[0053] At low temperatures, the viscosity of the lubricating oil in the gearbox increases significantly. For example, the viscosity of commonly used mineral-based lubricants can increase several times when the temperature drops from 25°C to 0°C. This increased viscosity impairs the lubricant's fluidity, making it difficult to form a uniform oil film on components like gears and bearings. This reduces lubrication effectiveness and increases friction between gears. In severe cases, it can cause gear transmission jamming, impacting the pelletizer's normal operation. Low temperatures not only increase the viscosity of the lubricating oil but also significantly reduce its fluidity. Bio-pellet mills must maintain a certain level of pelletizing efficiency and quality during production, requiring the gearbox to maintain excellent transmission performance even in low-temperature environments. If the lubricating oil in the gearbox degrades due to low temperatures, energy losses in the gear transmission increase, reducing transmission efficiency. For example, a 10% decrease in transmission efficiency can lead to a 15%-20% drop in overall pelletizer efficiency, making it impossible to meet production requirements.
[0054] exist Figure 5 -picture Figure 7 In the figure, the heating mechanism 200 includes a heating chamber 210 , and electric heating tubes 220 are arranged inside the heating chamber 210 . The electric heating tubes 220 are evenly distributed in a staggered manner inside the heating chamber 210 .
[0055] The improvement lies in that the heating chamber 210 is located below the oil tank 310 .
[0056] Furthermore, the height of the top of the oil groove 310 is higher than the height of the bottoms of the two gear bodies 130 .
[0057] It should be noted that because air has a relatively small heat capacity, both heating and cooling rates are relatively fast, enabling the system to respond quickly when adjusting temperature. When the lubricating oil temperature needs to be adjusted, the power of the electric heating pipe 220 is adjusted to change the air temperature. The air can quickly transfer heat to the lubricating oil in the oil tank 310, achieving rapid temperature adjustment and facilitating precise control of the lubricating oil temperature.
[0058] After the air is heated, a hot air flow is formed within the heating chamber 210. The hot air can flow in all directions around the oil tank 310, heating the oil tank 310 from all directions. Compared to directly heating the oil tank 310, this method allows all parts of the oil tank 310 to receive heat more evenly, thereby making the temperature of the lubricating oil in the oil tank 310 more uniform and avoiding local overheating or overcooling. Air has good thermal diffusivity. During its flow, the heated air continuously exchanges heat with the surface of the oil tank 310. The heat can quickly diffuse across the surface of the oil tank 310 and then be evenly transferred to the lubricating oil in the oil tank 310, further ensuring the uniformity of the lubricating oil temperature.
[0059] Direct heating of the oil tank 310 could cause local overheating, leading to oxidation, deterioration, or even combustion of the lubricating oil. However, heating with air as the intermediate medium, due to its relatively low specific heat capacity and slower temperature rise, can transfer heat more evenly to the oil tank 310. This effectively avoids quality issues associated with local overheating and improves the safety of the entire heating process.
[0060] For a pair of meshing gear bodies 130, the lubricating oil distributed radially therebetween maintains a uniform temperature distribution as soon as the meshing and rotating gear bodies 130 begin operation. However, the lubricating oil distributed axially, that is, on either side of the gear bodies 130, still experiences uneven temperature distribution, as the rotation of the gear bodies 130 is less likely to cause disturbances in the surrounding area.
[0061] Based on the above description, the following Figure 5 、 8 9 discloses a specific structure of the spoiler module 320. The spoiler module 320 includes a plurality of symmetrically arranged guide plates 321. Along the radial direction of the gear body 130, the distance between the guide plates 321 and the gear body 130 gradually decreases.
[0062] Furthermore, each guide plate 321 is provided with a plurality of guide holes along the axial direction of the gear body 130 .
[0063] Furthermore, the plurality of guide plates 321 are used to divide the oil tank 310 into a plurality of heating zones, and the plurality of heating zones are used to accelerate the temperature change rate of the lubricating oil in the oil tank 310 .
[0064] It should be disclosed that the guide plate 321 is made of heat-conducting material.
[0065] That is, when the gear body 130 rotates in the lubricating oil in the oil groove 310, it will drive the surrounding lubricating oil to move together. The two symmetrically arranged guide plates 321 will divert the lubricating oil flow driven by the gear body 130, causing the lubricating oil to flow to the area between the two guide plates 321 and between the guide plates 321 and the side walls of the oil groove 310. Because the radial spacing of the guide plates 321 along the gear body 130 gradually decreases, the lubricating oil will be guided by the shape of the guide plates 321 when flowing through the guide plates 321, and will flow in the direction specified by the guide plates 321. That is, the lubricating oil will flow along the radial direction of the gear body 130 from the position with larger spacing to the position with smaller spacing. During this process, the flow direction of the lubricating oil constantly changes, thereby achieving a disturbing effect on the lubricating oil.
[0066] According to Bernoulli's principle, the pressure of a fluid is low where the flow rate is high, and high where the flow rate is low. When the lubricating oil flows through the area between the two guide plates 321, the flow rate of the lubricating oil will gradually increase due to the gradual decrease in the spacing between the guide plates 321, thereby forming a relatively low pressure in this area. In the area between the outside of the guide plate 321 and the side wall of the oil groove 310, the flow rate of the lubricating oil is relatively slow and the pressure is relatively high. This pressure difference will cause the lubricating oil to flow from the area with higher pressure (outside the guide plate 321) to the area with lower pressure (between the guide plates 321), further enhancing the turbulence effect of the lubricating oil and causing the lubricating oil to form a more complex and turbulent flow state in the oil groove 310.
[0067] Through the guidance of the guide plate 321 and the effect of the pressure difference, the lubricating oil forms flows of different directions and speeds in the oil groove 310, so that lubricating oils at different positions, different temperatures and different properties can be fully mixed. Lubricating oils that may originally have temperature stratification or uneven composition can be mixed more evenly under the action of turbulence, thereby improving the overall performance of the lubricating oil. Turbulence increases the contact area between the lubricating oil and the side walls of the oil groove 310 and the surrounding air, and the contact time becomes longer. On the one hand, the lubricating oil can transfer the heat generated by the operation of the gear body 130 to the side walls of the oil groove 310 more quickly, and then dissipate it into the surrounding environment through the side walls of the oil groove 310; on the other hand, the enhanced convection effect also makes the heat exchange between the lubricating oil and the surrounding air more complete, thereby effectively improving the heat dissipation efficiency and preventing the lubricating oil from losing performance due to excessive temperature.
[0068] The deflector 321, made of a thermally conductive material, quickly dissipates heat, preventing deformation, aging, or even damage caused by prolonged exposure to high temperatures. This extends the service life of the deflector 321, ensuring it can continue to stably perform its functions of guiding and dividing the oil tank 310, and safeguarding the normal operation of the entire system. This timely heat dissipation helps prevent localized oil temperature rise, maintaining a more uniform and stable oil temperature within the oil tank 310. This is crucial for processes requiring precise oil temperature control, ensuring the lubricant operates within the appropriate temperature range.
[0069] The guide holes opened along the axial direction of the gear body 130 can form a more complex flow path for the lubricating oil between different areas, thereby enhancing the turbulence effect of the lubricating oil. When the lubricating oil passes through the guide holes, the flow rate and flow direction will change, forming different degrees of convection and mixing with the surrounding lubricating oil, further improving the uniformity of the oil temperature and the overall performance of the lubricating oil. The guide holes provide more flow channels for the lubricating oil, increase the contact area and contact time between the lubricating oil and the guide plate 321 and the surrounding environment, and are conducive to the transfer and exchange of heat. The lubricating oil can absorb or release heat more effectively, thereby improving the heat transfer efficiency of the entire oil tank 310 and helping to achieve more precise temperature control.
[0070] It should be noted that multiple heating zones can be heated or stopped independently according to actual needs, avoiding the heat waste that may occur when the entire oil tank 310 is heated over a large area. When only part of the area needs to be heated, only the heating equipment in the corresponding heating zone can be turned on, which reduces energy consumption, improves energy utilization efficiency, and reduces production costs. If a heating zone fails or has an abnormal temperature, since each heating zone is relatively independent, it will not have a direct impact on other heating zones, thereby enhancing the stability and reliability of the entire system. This facilitates the timely discovery and handling of problems, reduces the risk of the entire system shutting down due to local failures, and improves the operating efficiency of the equipment and the continuity of production.
[0071] In summary, the working principle of the present invention is as follows:
[0072] First, the pelletizer 100 is started. When the output shaft of the diesel engine 140 drives the coaxial drive disc 150, the circumferential motion of the drive disc 150 is transmitted to the belt 160 through friction, causing the belt 160 to move along the outer circumference of the drive disc 150. Similarly, friction between the moving belt 160 and the other drive disc 150 transmits the motion of the belt 160 to the other drive disc 150, causing the other drive disc 150 to rotate in the direction of the belt 160's motion. This further transfers power from the diesel engine 140 from one drive disc 150 to the other. Driven by two intermeshing gear bodies 130, the two crushing rollers 120 rotate toward each other, and the dead branches and leaves added to the pelletizing box 110 enter the gap between the two crushing rollers 120. As the crushing rollers 120 rotate, the dead branches and leaves are subjected to forces such as compression, shearing, and friction on the surfaces of the two crushing rollers 120. The dead branches and leaves are gradually broken into smaller particles, ultimately achieving the purpose of breaking the dead branches and leaves into particles. Prior to this, the power supply of the electric heating tube 220 is turned on, and the electric heating tube 220 heats the lubricating oil in each heated area in the oil tank 310 above it. When the gear body 130 rotates in the lubricating oil in the oil tank 310, it will drive the surrounding lubricating oil to move together. The two symmetrically arranged guide plates 321 will divert the lubricating oil flow driven by the gear body 130, so that the lubricating oil flows to the area between the two guide plates 321 and between the guide plates 321 and the side walls of the oil tank 310. Since the radial spacing of the guide plates 321 gradually decreases along the gear body 130, the lubricating oil will be guided by the shape of the guide plates 321 when flowing through the guide plates 321, and will flow in the direction specified by the guide plates 321. That is, the lubricating oil flows radially along the gear body 130 from locations with larger spacing to locations with smaller spacing. During this process, the flow direction of the lubricating oil constantly changes, thereby achieving a turbulent effect on the lubricating oil. Through the guidance of the guide plate 321 and the effect of the pressure difference, the lubricating oil forms flows of different directions and speeds within the oil groove 310, allowing lubricating oils of different locations, different temperatures, and different properties to be fully mixed. Lubricating oils that may originally have temperature stratification or uneven composition can be more evenly mixed together under the effect of turbulence. The turbulence increases the contact area between the lubricating oil and the side walls of the oil groove 310 and the surrounding air, and the contact time is prolonged. On the one hand, the lubricating oil can transfer the heat generated by the operation of the gear body 130 to the side walls of the oil groove 310 more quickly, and then dissipate it into the surrounding environment through the side walls of the oil groove 310. On the other hand, the enhanced convection effect also makes the heat exchange between the lubricating oil and the surrounding air more complete, thereby effectively improving the heat dissipation efficiency.
