Description

Technical Field

[0001] The present invention relates to the technical field of cooling devices, and more specifically, to a cooling device for biomass fuel production. Background Art

[0002] During the production process of biomass fuel, the processed biomass fuel usually has a relatively high temperature and needs to be cooled to ensure the quality and stability of the product. Due to its efficient cooling principle, the countercurrent cooler has been widely used in the field of biomass fuel cooling.

[0003] However, the discharge flap of the cooler is usually installed inside the cooler, and each flap is installed independently. Due to the continuous friction between the flaps and the biomass fuel, they need to be replaced frequently. When replacing the flaps, workers need to enter the inside of the cooler and disassemble and install each flap in turn. This process not only has a narrow operating space, but also requires a lot of time and energy, resulting in a decrease in replacement efficiency; moreover, the cooler mainly relies on air cooling to cool the biomass fuel, and this single air cooling method has a slow cooling speed. The long cooling time not only reduces the production efficiency, but also increases the production cost; at the same time, the stirring range of the stirring component in the cooler is limited, and it is impossible to fully turn and mix the biomass fuel, which makes the biomass fuel unevenly heated during the cooling process, with some areas cooling too fast and some areas cooling insufficiently, seriously affecting the consistency of the cooling effect.

[0034] In order to make the technical means, creative features, achieved purposes and effects of the present invention easy to understand, the present invention will be further described below in conjunction with specific embodiments

[0035] Such as Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 、 Figure 5 、 Figure 6 、 Figure 7 、 Figure 8 、 Figure 9 And Figure 10As shown in the figure, a cooling device for biomass fuel production according to the present invention includes a cooler body 1, a discharging structure 2 installed on the cooler body 1, an anti-rotation structure 6 installed in the discharging structure 2, a stirring structure 3 installed in the cooler body 1, a cooling structure 5 installed in the cooler body 1, a mesh plate 7 installed in the cooler body 1, and an exhaust device 8 installed on the cooler body 1; the discharging structure 2 includes a plurality of mounting shafts 201 rotatably connected to the cooler body 1 and flap plates 202 slidably connected to the mounting shafts 201. A positioning strip 210 is fixedly connected to the mounting shaft 201, and the flap plate 202 is slidably connected to the positioning strip 210. A rotating ring 203 is rotatably connected to the flap plate 202. An installation frame 204 is detachably connected to the cooler body 1, and the rotating ring 203 is rotatably connected to the installation frame 204. A plug-in block 205 is slidably connected in the cooler body 1, and the plug-in block 205 is engaged with the installation frame 204. A lead screw 206 is rotatably connected in the cooler body 1, and the plug-in block 205 is threadedly connected to the lead screw 206; the anti-rotation structure 6 includes two stop bars 601 slidably connected in the installation frame 204 and a mounting plate 602 fixedly connected between the two stop bars 601. The mounting plate 602 is slidably connected to the installation frame 204. A tension spring 603 is fixedly connected between the mounting plate 602 and the installation frame 204. A driving block 604 is fixedly connected to the mounting plate 602, and the driving block 604 is slidably connected to the installation frame 204. The plug-in block 205 is slidably matched with the driving block 604.

[0036] Specifically, as Figure 1 , Figure 3 , Figure 4 , Figure 7 and Figure 8As shown, a connecting shaft 207 is rotatably connected to the cooler body 1. A pulley 208 is fixedly connected to the connecting shaft 207. The two pulleys 208 are driven by a belt. A crank 209 is fixedly connected to the connecting shaft 207. The mounting shaft 201 is driven by a driving structure 4. The driving structure 4 includes a driving rod 401 fixedly connected to the mounting shaft 201 and a first rotating shaft 402 rotatably connected to the driving rod 401. A connecting rod 403 is rotatably connected between the plurality of first rotating shafts 402. A mounting block 407 is fixedly connected to the cooler body 1. A fixed shaft 406 is rotatably connected to the mounting block 407. A hydraulic rod 405 is fixedly connected to the fixed shaft 406. The telescopic end of the hydraulic rod 405 is rotatably connected to a second rotating shaft 404. The connecting rod 403 is rotatably connected to the second rotating shaft 404. When discharging is required, by starting the hydraulic rod 405, when the telescopic end of the hydraulic rod 405 extends, it drives the connecting rod 403 to move through the second rotating shaft 404. When the connecting rod 403 moves, it drives the plurality of driving rods 401 to rotate through the first rotating shaft 402. When the driving rod 401 rotates, it drives the mounting shaft 201 to rotate. Due to the setting of the positioning strip 210, the mounting shaft 201 can drive the flap 202 to rotate, so that there is a gap between the flaps 202, facilitating the biomass fuel to slide from the gap to the bottom of the cooler body 1. When the flap 202 needs to be replaced, the connecting shaft 207 can be rotated by the crank 209. When the pulley 208 on the connecting shaft 207 rotates, it drives the lead screw 206 to rotate through the cooperation of the belt and another pulley 208. When the lead screw 206 rotates, the plug-in block 205 is driven to move downward by the thread. When the plug-in block 205 gradually moves downward, it will no longer contact the inclined surface of the driving block 604. At this time, the mounting plate 602 will drive the blocking rod 601 to move under the action of the tension spring 603. When the blocking rod 601 reaches a certain position, it can block and limit the flap 202. When the plug-in block 205 is no longer engaged with the mounting frame 204, the mounting frame 204 can be slid between the cooler body 1. By driving the plurality of flaps 202 through the mounting frame 204 and the rotating ring 203, the mounting frame 204 and the flaps 202 can be disengaged from the mounting shaft 201 and the positioning strip 210, and the disassembly can be completed. By installing the flap 202 on the mounting frame 204 through the rotating ring 203, during disassembly, by disassembling the mounting frame 204, the plurality of flaps 202 can be disassembled and replaced, improving the replacement efficiency. At the same time, when installing the flap 202, only need to insert another mounting frame 204 equipped with the flap 202 between the cooler body 1. During insertion, since the two blocking rods 601 extend out of the mounting frame 204, it can prevent the flap 202 from rotating under the action of gravity, which affects the replacement of the flap 202. When the mounting frame 204 is inserted into the cooler body 1, through the sliding cooperation of the inclined surface of the plug-in block 205 and the inclined surface of the driving block 604, the driving block 604 drives the mounting plate 602 to slide.Drive the mounting plate 602 to drive the two retaining bars 601 to contract into the mounting frame 204, so as to prevent the retaining bars 601 from affecting the rotation of the flap 202.

[0037] Specifically, as Figure 1 , Figure 2 and Figure 6 shown, the stirring structure 3 includes three stirring shafts 301 rotatably connected in the cooler body 1 and worm wheels 302 fixedly connected to the stirring shafts 301. A spiral blade 305 is fixedly connected to the stirring shaft 301, and a stirring rod 306 is fixedly connected to the stirring shaft 301. A worm 303 is rotatably connected in the cooler body 1, and the worm wheel 302 meshes with the worm 303. A feed hopper 307 is fixedly connected to one of the stirring shafts 301, and a feed pipe 308 is fixedly connected to the feed hopper 307. A motor 304 is installed on the cooler body 1, and the worm 303 is fixedly connected to the output shaft of the motor 304. First, the biomass fuel slides from the feed inlet at the top of the cooler body 1 into the feed pipe 308, and then slides from the feed pipe 308 into the feed hopper 307. During feeding, by starting the motor 304, when the output shaft of the motor 304 rotates, it drives the worm 303 to rotate. The worm 303 drives the three worm wheels 302 to rotate. When the worm wheels 302 rotate, they drive the stirring shafts 301 to rotate. When the stirring shafts 301 rotate, they drive the feed hopper 307 to rotate. The continuous rotation of the feed hopper 307 can evenly add the biomass fuel into the cooler body 1. When the biomass fuel accumulates in the cooler body 1, the stirring rod 306 will stir the internal biomass fuel. At the same time, the stirring shaft 301 will drive the spiral blade 305 to rotate, turn over the material, and convey the material at the bottom upward, improving the stirring effect. The spiral blade 305 conveys the biomass fuel at the bottom upward, and at the same time cooperates with the stirring rod 306 to assist in stirring. The two work together to achieve the all-round turning and dispersion of the biomass fuel, greatly increasing the contact area between the biomass fuel and the cooling medium, and improving the cooling uniformity and efficiency.

[0038] Specifically, as Figure 2 , Figure 10 and Figure 11As shown, the cooling structure 5 includes a pipe 501 installed inside the cooler body 1 and a connecting pipe 502 installed on the pipe 501. An installation pipe 503 is fixedly connected to the connecting pipe 502. A fixed pipe 509 is installed on the pipe 501. Two positioning blocks 504 are slidably connected to the installation pipe 503. An installation ring 505 is fixedly connected between the two positioning blocks 504. The installation ring 505 is slidably connected to the installation pipe 503. A filter screen 506 is fixedly connected to the installation ring 505. A pull rod 507 is fixedly connected to the installation ring 505. A sealing groove 508 is provided on the installation pipe 503. During the cooling process, air will enter the cooler body 1 from the air inlet at the mesh plate 7. The incoming cold air flows from bottom to top, forming a countercurrent with the high-temperature biomass fuel particles moving from top to bottom. The cold air first contacts the low-temperature fuel particles that have already undergone partial cooling, and then gradually contacts the fuel particles with higher temperatures. The air flow direction is opposite to the material flow direction. In this process, the cold air absorbs the heat of the fuel particles, causing the temperature of the fuel particles to gradually decrease, while the temperature of the cold air itself gradually increases. The heat will be taken out of the cooler body 1 by the exhaust device 8. At the same time, an external water pipe is docked with the installation pipe 503, and a sealing ring is placed between the external water pipe and the installation pipe 503. The sealing ring is placed in the sealing groove 508 to improve the sealing performance between the external water pipe and the installation pipe 503. When the external water source enters the installation pipe 503, the impurities in the water will be blocked by the filter screen 506. Filtering impurities through the filter screen 506 can prevent impurities from entering the pipe 501 from the external water source and forming scale, which affects the heat exchange effect. When the filter screen 506 needs to be replaced, only the external water pipe and the installation pipe 503 need to be disassembled, and then the pull rod 507 is pulled to make the installation ring 505 and the positioning blocks 504 both slip off the installation pipe 503, and the replacement of the filter screen 506 can be completed. At the same time, water will enter the pipe 501. The water flows in the pipe 501 and passes through various parts of the cooler body 1. Since the heat dissipated by the biomass fuel is transferred to the shell of the cooler body 1, the temperature of the shell increases. The temperature difference between the pipe 501 and the shell is relatively large. The heat is transferred from the shell to the pipe 501 through heat conduction and then absorbed by the water. The temperature of the water after absorbing the heat increases and continues to flow in the pipe 501 and finally discharges from the fixed pipe 509, thereby cooling the biomass fuel. The cold air provided by the air-cooling system flows through a specific channel of the cooler body 1, taking away part of the heat, and cooperating with the water in the pipe 501 to absorb heat from the shell of the cooler body 1. The two cooperate with each other to cool the biomass fuel in the cooler body 1, further improving the cooling efficiency and uniformity.

[0039] When the present invention is in use, first, the biomass fuel slides from the feed inlet at the top of the cooler body 1 into the blanking pipe 308, and then slides from the blanking pipe 308 into the blanking hopper 307. When blanking, by starting the motor 304, when the output shaft of the motor 304 rotates, it drives the worm 303 to rotate. The worm 303 drives three worm wheels 302 to rotate. When the worm wheels 302 rotate, they drive the stirring shaft 301 to rotate. When the stirring shaft 301 rotates, it drives the blanking hopper 307 to rotate. The continuous rotation of the blanking hopper 307 can evenly add the biomass fuel into the cooler body 1. When the biomass fuel in the cooler body 1 accumulates, the stirring rod 306 will stir the biomass fuel inside. At the same time, the stirring shaft 301 will drive the spiral blade 305 to rotate, turn over the materials, and convey the materials at the bottom upward, improving the stirring effect. The spiral blade 305 conveys the biomass fuel at the bottom upward, and at the same time cooperates with the stirring rod 306 to assist in stirring. The two work together to realize the all-round turning and dispersion of the biomass fuel, greatly increasing the contact area between the biomass fuel and the cooling medium, and improving the cooling uniformity and efficiency;

[0040] During the cooling process, air will enter the cooler body 1 through the air inlet at the wire mesh plate 7. The incoming cold air flows from bottom to top, forming a countercurrent with the high-temperature biomass fuel particles moving from top to bottom. The cold air first contacts the low-temperature fuel particles that have already undergone partial cooling, and then gradually contacts the fuel particles with higher temperatures. The air flow direction is opposite to the material flow direction. During this process, the cold air absorbs the heat of the fuel particles, gradually reducing the temperature of the fuel particles, while the temperature of the cold air itself gradually increases. The heat will be carried out of the cooler body 1 by the exhaust device 8. At the same time, an external water pipe is docked with the installation pipe 503, and a sealing ring is placed between the external water pipe and the installation pipe 503. The sealing ring is placed in the sealing groove 508 to improve the sealing performance between the external water pipe and the installation pipe 503. When external water source enters the installation pipe 503 from the water pipe, impurities in the water will be blocked by the filter screen 506. Filtering impurities through the filter screen 506 can prevent impurities from entering the pipeline 501 from the external water source and forming scale, which affects the heat exchange effect. When the filter screen 506 needs to be replaced, only need to disassemble the external water pipe and the installation pipe 503, and then pull the pull rod 507 to make the installation ring 505 and the positioning block 504 both slip off the installation pipe 503, then the replacement of the filter screen 506 can be completed. At the same time, water will enter the pipeline 501. The water flows in the pipeline 501 and passes through various parts of the cooler body 1. Since the heat emitted by the biomass fuel is transferred to the shell of the cooler body 1, the temperature of the shell increases. There is a large temperature difference between the pipeline 501 and the shell. The heat is transferred from the shell to the pipeline 501 through heat conduction and then absorbed by the water. The temperature of the water after absorbing the heat increases and continues to flow in the pipeline 501 and finally discharges from the fixed pipe 509, thereby cooling the biomass fuel. The cold air provided by the air-cooling system flows through a specific channel of the cooler body 1, taking away part of the heat, and cooperating with the water in the pipeline 501 to absorb heat from the shell of the cooler body 1. The two cooperate with each other to cool the biomass fuel in the cooler body 1, further improving the cooling efficiency and uniformity;

[0041] When unloading is required, the hydraulic rod 405 is started. When the telescopic end of the hydraulic rod 405 is extended, the connecting rod 403 is driven to move through the second rotating shaft 404. When the connecting rod 403 moves, the multiple driving rods 401 are driven to rotate through the first rotating shaft 402. When the driving rod 401 rotates, it drives the installation shaft 201 to rotate. Due to the setting of the positioning strip 210, the installation shaft 201 can drive the flap 202 to rotate, so that there is a gap between the flaps 202, which is convenient for the biomass fuel to slide from the gap to the bottom of the cooler body 1. When the flap 202 needs to be replaced, The crank 209 can be used to drive the connecting shaft 207 to rotate. When the pulley 208 on the connecting shaft 207 rotates, the belt cooperates with another pulley 208 to drive the screw rod 206 to rotate. When the screw rod 206 rotates, the thread drives the plug-in block 205 to move downward. When the plug-in block 205 gradually moves downward, it will no longer conflict with the inclined surface of the driving block 604. At this time, the mounting plate 602 will drive the blocking rod 601 to move under the action of the tension spring 603. When the blocking rod 601 reaches a certain position, it can resist and limit the flap 202. When the plug-in block 205 is no longer in contact with the mounting frame 20 After the engagement, the mounting frame 204 can be slid between the cooler body 1, and the mounting frame 204 and the rotating ring 203 can drive the multiple flaps 202 to move, so that the mounting frame 204 and the flaps 202 can be slipped off the mounting shaft 201 and the positioning bar 210, and the disassembly can be completed. The flaps 202 are mounted on the mounting frame 204 through the rotating ring 203. When disassembling, the multiple flaps 202 can be disassembled and replaced by disassembling the mounting frame 204, thereby improving the replacement efficiency. At the same time, when installing the flap 202, it is only necessary to replace another flap 202 with the flap 202. The installation frame 204 can be plugged into the cooler body 1. During the plugging, the two baffle bars 601 extend out of the installation frame 204, which can prevent the flap 202 from rotating under the action of gravity and affecting the replacement of the flap 202. After the installation frame 204 is plugged into the cooler body 1, the inclined surface of the plug-in block 205 slides with the inclined surface of the driving block 604, so that the driving block 604 drives the installation plate 602 to slide, and the installation plate 602 drives the two baffle bars 601 to retract into the installation frame 204, thereby preventing the baffle bars 601 from affecting the rotation of the flap 202.
