Description

Technical Field

[0001] This utility model relates to the technical field of biomass pellets, and in particular to a biomass pellet dehydration and drying equipment. Background Technology

[0002] After biomass pellets are produced and shaped, they need to be dehydrated and dried to harden and set their shape. Chinese utility model patent CN219551055U discloses a dehydration and drying device for biomass pellet processing. This device includes a chamber, a rotating motor, and a stirring shaft. The rotating motor is mounted on the top of the chamber, and the output end of the motor is securely connected to the stirring shaft. Stirring blades are mounted on the outer side of the stirring shaft. A support cylinder is installed inside the chamber, and mounting columns are installed on both sides of the support cylinder. One side of each mounting column is connected to the inner wall of the chamber. A discharge port is opened at the bottom of the support cylinder, and a conveying pipe is connected to the bottom of the discharge port. This utility model uses jet nozzles A and B to allow hot air to enter the interior of the chamber. The hot air surrounds the support cylinder, increasing the contact area between the biomass pellets and improving drying efficiency. The stirring shaft, in conjunction with the stirring blades, stirs the biomass pellets inside the support cylinder, increasing the gaps between the pellets, facilitating the flow of hot air, ensuring uniform heating of the biomass pellets, and resulting in consistent drying quality.

[0003] However, the above-mentioned dehydration and drying device uses stirring blades to stir the biomass pellets, which makes the un-dried and hardened biomass pellets easy to break and produce a large amount of debris. These debris cannot be effectively discharged, resulting in a large amount of debris mixed in after the biomass pellets are dehydrated and dried, which reduces the uniformity of the biomass pellets. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model provides a biomass pellet dehydration and drying equipment that can discharge the fragments of biomass pellets during the dehydration and drying process, thereby improving the product uniformity of biomass pellets.

[0005] This utility model discloses a biomass pellet dehydration and drying equipment, including a heating box and a fan. The fan is installed on the heating box, which is equipped with a heating system. The fan outputs hot air from inside the heating box to form hot air. The equipment also includes a drying box body, a first discharge chute, a second discharge chute, a soft filter, a first guide plate, and a second guide plate. The drying box body is installed on the heating box. The first discharge chute is located on the right edge of the drying box, facing downwards to the right, and the second discharge chute is located on the left edge of the drying box, facing downwards to the left. A soft filter is installed at the bottom of the drying box, above the air outlet of the fan. The first guide plate is installed obliquely on the right side of the upper port of the drying box, with its left end extending into the middle of the drying box and its right end extending above the first discharge chute. The second guide plate is installed obliquely on the left side of the upper port of the drying box, with its right end extending into the middle of the drying box and below the left end of the first guide plate. A gap is set between the right ends of the first and second guide plates, and the left end of the second guide plate extends into the upper part of the discharge trough. The gap between the left end of the first guide plate and the right end of the second guide plate forms a feeding channel. During operation, biomass pellets are poured into the upper part of the first and second guide plates and enter the drying chamber through the feeding channel and are caught by the soft filter screen. The heating system in the heating chamber is turned on to heat the air in the heating chamber. The fan runs to draw out the hot air in the heating chamber to form hot air and transport it to the soft filter screen and the interior of the drying chamber. The hot air dehydrates and dries the biomass pellets. The guiding effect of the first and second guide plates causes the hot air to be discharged from the drying chamber along the lower end face of the first guide plate and the lower end face of the second guide plate and the discharge trough. This allows the broken particles mixed in the biomass pellets to be discharged with the hot air. The broken particles are collected through the receiving box and can be granulated again. Compared with the existing technology, the broken particles of biomass pellets can be discharged during the dehydration and drying process, improving the uniformity of the biomass pellets.

[0006] Preferably, it also includes a filter plate, which is installed between the left end of the first guide plate and the right end of the second guide plate; the filter plate filters the feed of biomass pellets, filtering and intercepting large particulate impurities and biomass pellets.

[0007] Preferably, it also includes two mounting brackets, multiple shafts, and multiple levers. The two mounting brackets are respectively installed on both sides of the drying chamber. The two ends of the multiple shafts are rotatably connected to the two mounting brackets. Multiple levers are installed on each of the two shafts. The multiple levers actuate the lower end face of the soft filter screen. The multiple shafts are driven by a drive mechanism, which causes the multiple shafts to drive the multiple levers to rotate. The multiple levers actuate the lower end face of the soft filter screen, causing the biomass particles on the soft filter screen to be turned over, so that the biomass particles have more sufficient contact with the hot air.

[0008] Preferably, the device further includes multiple worm gears, a rotating shaft, multiple worms, and a driver. The multiple worm gears are concentrically mounted on the ends of multiple shafts. The rotating shaft is rotatably mounted on a mounting bracket. Multiple worms are concentrically mounted on the worm gears, and the multiple worms mesh with the multiple worm gears. The driver is mounted on the mounting bracket, and the output shaft of the driver is connected to the rotating shaft for transmission. The driver drives the rotating shaft and multiple worms to rotate. The multiple worms mesh with and drive the multiple worm gears to rotate. The multiple worm gears drive the multiple shafts to rotate. The multiple shafts drive the multiple levers to rotate. The multiple levers actuate the lower end face of the soft filter screen, thereby driving the multiple shafts.

[0009] Preferably, the worm teeth of two adjacent worms are arranged in opposite directions; multiple worm wheels mesh with multiple worms respectively. Through the above arrangement, multiple shafts and multiple levers rotate in opposite directions in sequence to achieve different actuation effects on the soft filter screen.

[0010] Preferably, the assembly also includes a receiving box, multiple inclined plates one and multiple inclined plates two. The receiving box is installed on the heating box, located between the fan and the soft filter. Multiple ventilation openings are provided at the bottom of the receiving box. Multiple inclined plates one are respectively installed on one side of each ventilation opening, and multiple inclined plates two are respectively installed on the other side of each ventilation opening. Inclined plates one and two located on opposite sides of the same ventilation opening are arranged in a herringbone pattern, with the upper end of inclined plate two located inside and below the upper end of inclined plate one. An air outlet is provided between the end of the first inclined plate and the upper end of the second inclined plate. Before the blower is turned on, the fragments of biomass pellets fall into the receiving box through the soft filter screen and fall between multiple inclined plates one and multiple inclined plates two. The herringbone arrangement of inclined plates one and two prevents the fragments from falling into the blower. The fragments will not cause pollution to the blower and the equipment in the heating box. The hot air output by the blower is delivered to the soft filter screen through the air outlet between multiple inclined plates two and multiple inclined plates one. The hot air heats the receiving box and can dehydrate and dry the fragments on the receiving box.

[0011] Preferably, it also includes columns and push rods. Several columns are provided and are vertically installed on the heating box. The upper end of the column is rotatably connected to the left side of the drying box. The lower end of the push rod is rotatably connected to the heating box, and the upper end of the push rod is rotatably connected to the right side of the drying box. The columns and push rods are arranged relatively to the left and right. When dehydrating and drying the biomass pellets, the columns and push rods support the drying box to keep it horizontal. After the biomass pellets are dehydrated and dried, the push rods retract, causing the right side of the drying box to tilt downwards, so that the biomass pellets are discharged through the discharge chute, achieving efficient discharge.

[0012] Compared with the prior art, the beneficial effects of this utility model are: it can remove the fragments of biomass pellets during the dehydration and drying process, thereby improving the uniformity of biomass pellet products. Attached Figure Description

[0021] To facilitate understanding of this utility model, a more complete description will be given below with reference to the accompanying drawings. This utility model can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided to make the disclosure of this utility model more thorough and complete. Example 1

[0022] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 7As shown, a biomass pellet dehydration and drying device includes a heating chamber 1 and a blower 2. The blower 2 is installed on the heating chamber 1, and a heating system is installed inside the heating chamber 1. The blower 2 outputs hot air from inside the heating chamber 1 to form hot air. It also includes a drying chamber 3, a discharge chute 4, a discharge chute 5, a soft filter 6, a guide plate 7, and a guide plate 8. The drying chamber 3 is installed on the heating chamber 1. The right edge of the drying chamber 3 has a discharge chute 4 facing downward to the right, and the left edge of the drying chamber 3 has a discharge chute 5 facing downward to the left. A soft filter 6 is installed at the bottom, located above the air outlet of the fan 2. A guide plate 7 is installed obliquely on the right side of the upper port of the drying chamber 3, with its left end extending into the middle of the drying chamber 3 and its right end extending above the discharge chute 4. A guide plate 8 is installed obliquely on the left side of the upper port of the drying chamber 3, with its right end extending into the middle of the drying chamber 3 and below the left end of guide plate 7. A gap is provided between the left end of guide plate 7 and the right end of guide plate 8. The left end extends above the discharge trough 2 5; it also includes a filter plate 9, which is installed between the left end of the guide plate 1 7 and the right end of the guide plate 2 8; it also includes a receiving box 17, multiple inclined plates 18 and multiple inclined plates 2 19. The receiving box 17 is installed on the heating box 1 and is located between the blower 2 and the soft filter screen 6. Multiple ventilation openings are provided at the bottom of the receiving box 17. Multiple inclined plates 18 are respectively installed on one side of the multiple ventilation openings of the receiving box 17, and multiple inclined plates 2 19 are respectively installed on the other side of the multiple ventilation openings of the receiving box 17. The first inclined plate 18 and the second inclined plate 19 on the side are arranged in a herringbone shape, and the upper end of the second inclined plate 19 is located inside the lower end of the first inclined plate 18. An air outlet is provided between the upper end of the second inclined plate 19 and the upper end of the first inclined plate 18. It also includes a column 20 and a push rod 21. Several columns 20 are provided. The columns 20 are vertically installed on the heating box 1. The upper end of the column 20 is rotatably connected to the left side of the drying box 3. The lower end of the push rod 21 is rotatably connected to the heating box 1. The upper end of the push rod 21 is rotatably connected to the right side of the drying box 3. The columns 20 and the push rod 21 are arranged opposite each other to the left and right.

[0023] The gap between the left end of guide plate 7 and the right end of guide plate 8 forms a feeding channel. During operation, biomass pellets are poured above guide plate 7 and guide plate 8. Filter plate 9 filters the feed of biomass pellets, intercepting large particles and biomass pellets, and allowing the biomass pellets to enter the drying chamber 3 through the feeding channel and be caught by the soft filter screen 6. The fragments of biomass pellets fall through the soft filter screen 6 into the receiving box 17 and fall between multiple inclined plates 18 and 19. The herringbone arrangement of inclined plates 18 and 19 prevents fragments from falling into the blower 2, thus preventing the fragments from contaminating the equipment in the blower 2 and the heating chamber 1. The heating system in the heating chamber 1 is turned on to heat the air in the heating chamber 1, and the blower 2 runs to heat the air in the heating chamber 1. Hot air is drawn out to form hot air, which is then conveyed to the soft filter 6 through the air outlet between multiple inclined plates 19 and 18. The hot air heats the receiving box 17, which can dehydrate and dry the fragments on the receiving box 17, and conveys the hot air into the soft filter 6 and the interior of the drying chamber 3, so that the hot air dehydrates and dries the biomass pellets. The guiding effect of the guide plate 7 and the guide plate 8 causes the hot air to be discharged from the drying chamber 3 along the lower end face of the guide plate 7 and the discharge chute 4 and the lower end face of the guide plate 8 and the discharge chute 5, respectively. This allows the fragments mixed in the biomass pellets to be discharged with the hot air. The fragments can be collected in the receiving box and can be granulated again. Compared with the existing technology, the fragments of biomass pellets can be discharged during the dehydration and drying process, which improves the uniformity of the biomass pellets.

[0024] During the dehydration and drying of biomass pellets, the column 20 and push rod 21 support the drying chamber 3 to remain horizontal. After the biomass pellets are dehydrated and dried, the push rod 21 retracts, causing the right side of the drying chamber 3 to tilt downwards, allowing the biomass pellets to be discharged through the discharge chute 4, achieving efficient discharge. Example 2

[0025] like Figure 1 , Figure 2 , Figure 4 and Figure 6 As shown, based on Embodiment 1, it also includes two mounting brackets 10, multiple shafts 11, and multiple levers 12. The two mounting brackets 10 are respectively installed on both sides of the drying chamber 3. The two ends of the multiple shafts 11 are respectively rotatably connected to the two mounting brackets 10. Multiple levers 12 are installed on each of the two shafts 11, and the multiple levers 12 actuate the lower end face of the soft filter screen 6. It also includes multiple worm gears 13, a rotating shaft 14, multiple worms 15, and a driver 16. The multiple worm gears 13 are respectively concentrically installed on the ends of the multiple shafts 11. The rotating shaft 14 is rotatably installed on the mounting bracket 10. Multiple worms 15 are concentrically installed on the worm gears 13, and the multiple worms 15 mesh with the multiple worm gears 13 respectively. The driver 16 is installed on the mounting bracket 10, and the output shaft of the driver 16 is connected to the rotating shaft 14 for transmission. The worm teeth of two adjacent worms 15 are arranged in opposite directions.

[0026] The driver 16 drives the rotating shaft 14 and multiple worm gears 15 to rotate. The multiple worm gears 15 mesh with and drive multiple worm wheels 13 to rotate. The multiple worm wheels 13 drive multiple shafts 11 to rotate. The multiple shafts 11 drive multiple levers 12 to rotate. The multiple levers 12 move the lower end face of the soft filter screen 6, thereby driving the multiple shafts 11. This causes the multiple shafts 11 to drive the multiple levers 12 to rotate. The multiple levers 12 move the lower end face of the soft filter screen 6, causing the biomass pellets on the soft filter screen 6 to be turned over, so that the biomass pellets have more sufficient contact with the hot air.

[0027] like Figures 1 to 7 As shown, this utility model discloses a biomass pellet dehydration and drying device. During operation, biomass pellets are first poured above guide plate 7 and guide plate 8, and then enter the drying chamber 3 through the feeding channel, where they are caught by the soft filter screen 6. Particle fragments fall through the soft filter screen 6 into the receiving box 17. Then, the heating system in the heating chamber 1 is activated to heat the air inside. The fan 2 operates to extract the hot air from the heating chamber 1, forming hot air that is conveyed to the soft filter screen 6 and the interior of the drying chamber 3, thus dehydrating and drying the biomass pellets. Finally, multiple shafts 11 drive multiple levers 12 to rotate. Multiple levers 12 actuate the lower end face of the soft filter screen 6, causing the biomass pellets on the soft filter screen 6 to be turned over, so that the biomass pellets come into more thorough contact with the hot air. The guiding action of the first guide plate 7 and the second guide plate 8 causes the hot air to be discharged from the drying chamber 3 along the lower end face of the first guide plate 7 and the lower end face of the second guide plate 8 and the second discharge chute 5, respectively. This allows the fragments mixed in the biomass pellets to be discharged with the hot air. The fragments are collected through the receiving box and can be granulated again. Finally, after the biomass pellets are dehydrated and dried, the push rod 21 retracts, causing the right side of the drying chamber 3 to tilt downwards, so that the biomass pellets can be discharged through the discharge chute 4.

[0028] The main functions achieved by this utility model are:

[0029] 1. It can remove the fragments of biomass pellets during the dehydration and drying process, thereby improving the uniformity of biomass pellet products.

[0030] 2. Turn the biomass pellets by moving the soft filter 6 to make the biomass pellets come into more full contact with the hot air.

[0031] The biomass pellet dehydration and drying equipment of this utility model uses common mechanical methods for installation, connection, or setting. Any method that can achieve the beneficial effect can be implemented. The heating box 1, fan 2, soft filter 6, guide plate 1 7, guide plate 2 8, filter plate 9, shaft 11, lever 12, worm gear 13, rotating shaft 14, worm 15, driver 16, receiving box 17, column 20, and push rod 21 of the biomass pellet dehydration and drying equipment of this utility model are purchased from the market.
