Description

Technical Field

[0001] This utility model relates to the field of agricultural and forestry waste treatment technology, specifically to a cyclone centrifugal pyrolysis solid-liquid separation device for agricultural and forestry waste. Background Technology

[0002] When treating agricultural and forestry waste, pyrolysis is usually used. Pyrolysis is a thermal decomposition reaction in an anaerobic or low-oxygen environment that converts agricultural and forestry waste into high-value-added products such as biochar, bio-oil, and combustible gas, effectively solving the problem of waste accumulation and pollution. After the waste is pyrolyzed, a mixture of liquid and solid materials is produced. At this time, a separator is needed to effectively separate the solid and liquid. However, in traditional cyclone centrifugal separators, solid impurities are pushed and adhered to the inner wall of the separator by centrifugal force during solid-liquid separation. They cannot be effectively collected during subsequent cleaning, which reduces the solid-liquid separation and recovery effect.

[0003] Therefore, we propose a cyclone centrifugal pyrolysis solid-liquid separation device for agricultural and forestry waste to solve the above problems. Utility Model Content

[0026] This utility model discloses a cyclone centrifugal pyrolysis solid-liquid separation device for agricultural and forestry waste.

[0027] This utility model provides, for example Figure 1-4 The centrifugal cyclone centrifugal solid-liquid separation device for agricultural and forestry waste includes a support frame 1, a support pipe 2 fixedly inserted at the upper end of the support frame 1, a separator 3 rotatably sleeved at the upper end of the support pipe 2, two symmetrically arranged waste outlet pipes 4 connected to the bottom of the separator 3, a control valve 5 connected to the pipe wall of the waste outlet pipe 4, two symmetrically arranged overflow holes 6 opened at the upper end of the inner wall of the separator 3, and the interior of the separator 3 is connected to the support pipe 2.

[0028] The top of the support frame 1 is provided with a rotary centrifugal mechanism for driving the separator 3 to rotate. The rotary centrifugal mechanism includes a motor 11, which is fixedly mounted on the bottom of the upper end of the support frame 1. The output shaft extends out of the support frame 1 and is fixedly mounted with a drive gear 12. The wall of the support tube 2 is rotatably fitted with a transmission gear 13. The drive gear 12 and the transmission gear 13 are configured to cooperate. Two connecting rods 14 are fixedly mounted on the top of the transmission gear 13. The upper end of the connecting rods 14 is fixedly connected to the separator 3.

[0029] A vertical plate 7 is fixedly installed on the top of the support frame 1. An air guide pipe 8 is fixedly installed on the outer wall of the vertical plate 7. A through hole is opened at the lower end of the vertical plate 7 to accommodate the air guide pipe 8. An air blowing pipe 9 is connected to the upper end of the air guide pipe 8. Both ends of the air blowing pipe 9 extend into the separator 3 and are set towards the inner wall of the separator 3. An air pump 10 is connected to the pipe wall of the air guide pipe 8. The air pump 10 is fixedly connected to the vertical plate 7. A dust filter screen 24 is fixedly fitted at the lower end of the air guide pipe 8.

[0030] In order to control the intermittent blowing of gas and reduce the impact on the operation of the cyclone centrifuge, such as Figure 1 and Figure 3-4 As shown, a horizontal shaft 15 is rotatably inserted through the upper end of the air guide tube 8. A sealing plate 16 is fixedly sleeved on the shaft wall of the horizontal shaft 15. The sealing plate 16 is located inside the air guide tube 8 and contacts and cooperates with the inner wall of the air guide tube 8. A worm gear 17 is fixedly sleeved on the shaft wall of the horizontal shaft 15. A worm 18 is fitted on the worm gear 17. The lower end of the worm 18 is rotatably disposed in the support frame 1.

[0031] A transmission rod 19 is rotatably mounted on the top of the support frame 1. A sector gear 20 is fixedly mounted on the lower end of the transmission rod 19. A control spur gear 21 is fixedly mounted on the lower end of the worm gear 18. The sector gear 20 and the control spur gear 21 are configured to cooperate. Synchronous pulleys 22 are fixedly mounted on the output shafts of both the transmission rod 19 and the motor 11. A synchronous belt 23 is provided for the external transmission of the synchronous pulley 22.

[0032] Working principle: First, the solid-liquid mixture produced by the pyrolysis of agricultural and forestry waste is transported to the separator 3 through the support pipe 2. Then, the equipment is started. On one hand, the motor 11 in the rotating centrifugal mechanism is started. The output shaft of the motor 11 drives the drive gear 12 to rotate. Since the drive gear 12 and the transmission gear 13 that is rotated and sleeved on the wall of the support pipe 2 cooperate with each other, the drive gear 12 will drive the transmission gear 13 to rotate synchronously. The top of the transmission gear 13 is fixedly connected to the separator 3 through two connecting rods 14. Therefore, the transmission gear 13 will drive the separator 3 to rotate at high speed around the support pipe 2. Under the action of centrifugal force, the denser solid impurities in the mixture in the separator 3 are thrown to the inner wall of the separator 3, while the less dense liquid gathers in the central area of ​​the separator 3. As the liquid continues to increase, it will flow out through the two symmetrical overflow holes 6 opened at the upper end of the inner wall of the separator 3, realizing the initial separation of solid and liquid.

[0033] On the other hand, the air pump 10, which is connected to the wall of the air duct 8, is started. The air pump 10 draws in external air and delivers it into the air duct 8. The dust filter 24, which is fixedly sleeved at the lower end of the air duct 8, can filter the drawn-in air and prevent dust and impurities from entering and affecting the separation effect. At the same time, when the output shaft of the motor 11 rotates, it will drive the transmission rod 19, which is rotated on the top of the support frame 1, to rotate synchronously through the synchronous pulley 22 fixedly sleeved on its shaft wall and the synchronous belt 23 of the external transmission. When the transmission rod 19 rotates, it will drive the sector gear 20 fixedly sleeved at its lower end to rotate. When the sector gear 20 rotates to the control round tooth fixedly sleeved at the lower end of the worm gear 18, the transmission rod 19 will rotate. When the gear 21 meshes, it will drive the control spur gear 21 and worm 18 to rotate. The worm 18 is engaged with the worm wheel 17 fixedly sleeved on the shaft wall of the horizontal shaft 15. The rotation of the worm 18 will drive the worm wheel 17 and the horizontal shaft 15 to rotate. The rotation of the horizontal shaft 15 will drive the sealing plate 16 fixedly sleeved on its shaft wall to rotate inside the air guide pipe 8. When the sealing plate 16 rotates to the point that it no longer blocks the internal passage of the air guide pipe 8, the gas in the air guide pipe 8 can be smoothly delivered to the blowing pipe 9 connected to its upper end. The two ends of the blowing pipe 9 extend into the separator 3 and face the inner wall of the separator 3. The gas is blown towards the inner wall of the separator 3 through the opening of the blowing pipe 9, blowing off the solid impurities attached to the wall surface.

[0034] When the sector gear 20 rotates to disengage from and re-engage with the control spur gear 21, the worm gear 18 is driven, causing the horizontal shaft 15 to drive the sealing plate 16 back to its original position, re-sealing the internal channel of the air guide pipe 8 and stopping the blowing. This achieves intermittent gas blowing, reducing interference with the centrifugal process inside the separator 3. The blown-off solid impurities, along with other solid impurities, move towards the bottom of the separator 3 under the action of centrifugal force and gravity. When the separation operation reaches a certain stage, the control valve 5 connected to the wall of the impurity outlet pipe 4 is opened, and the solid impurities can be discharged through the two symmetrically arranged impurity outlet pipes 4, completing the entire solid-liquid separation and impurity collection process.

[0035] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
