Abstract

The present invention discloses a biomass gasification reactor with an anti-blocking function, which comprises a box body. Four corners of the bottom end of the box body are fixedly connected with bases. A condensing pipe is sleeved on the inner wall of the middle of the box body. A water inlet is arranged above the left side of the condensing pipe, and a water outlet is arranged below the right side of the condensing pipe. An inlet and an outlet are respectively fixedly connected to the outer walls on both sides of the heating coil, and the heating coil is respectively communicated with the inlet. This biomass gasification reactor with an anti-blocking function can crush waste of a certain volume, enabling the waste to be fully and rapidly subjected to high-temperature oxidation treatment, solving the problem that due to the uneven sizes of the waste put in, large-volume waste will have incomplete oxidation or slow oxidation rate during high-temperature oxidation treatment. The two baffles and the two turntables simultaneously delay the falling speed of the waste, solving the problem that the material after the existing treatment is prone to block the outlet.

However, in the processing of existing biomass gasification reactors, due to the uneven sizes of the waste materials put in, the small-sized ones are easy to process. If large-sized waste materials are treated by high-temperature oxidation, there will be problems such as incomplete oxidation or slow oxidation rate. At the same time, there is also the problem that the processed materials are likely to block the outlet. Summary of the Invention

A heating coil 9 is sleeved on the upper inner wall of the box body 1, and the box body 1 supports the heating coil 9. An inlet 10 and an outlet 11 are respectively fixedly connected to the outer walls on both sides of the heating coil 9, and the heating coil 9 is respectively communicated with the inlet 10 and the outlet 11. The externally connected high-pressure steam is introduced into the heating coil 9 through the inlet 10 to perform high-temperature treatment on the upper part of the box body 1, and then the steam is discharged through the outlet 11 to form a reciprocating cycle. A crushing mechanism 4 is installed inside the upper part of the box body 1, a material blocking mechanism 5 is installed inside the middle part of the box body 1, and a discharging mechanism 6 is installed inside the lower part of the box body 1.

[0018] The crushing mechanism 4 includes a first motor 401, a bracket 402, a first gear 403, a second gear 404, a rotating shaft 405, rotating teeth 406, stirring teeth 407, a first spring 408 and a top plate 409. The outer wall of the first motor 401 is sleeved on the upper inner wall of the bracket 402, and the bracket 402 supports the first motor 401. The bottom end of the bracket 402 is fixedly connected to the upper left top of the box body 1, and the box body 1 supports the bracket 402. The output shaft of the first motor 401 is rotatably connected to the first gear 403, and the output shaft of the first motor 401 drives the first gear 403 to rotate. The first gear 403 is meshed with the second gear 404, and the meshing force between the first gear 403 and the second gear 404 drives the second gear 404 to rotate. The middle inner wall of the second gear 404 is sleeved with a rotating shaft 405, and the second gear 404 drives the rotating shaft 405 to rotate. The rotating shaft 405 is provided with rotating teeth 406, and the rotating teeth 406 are rotatably connected to the box body 1 through the rotating shaft 405. The rotating teeth 406 rotate in the box body 1 through the rotating shaft 405. The rotating teeth 406 are both meshed with the stirring teeth 407. The rotating teeth 406 rotate and mesh with the two stirring teeth 407 to crush the material entering from the top of the box body 1, which is beneficial to improving work efficiency. The outer ends of the two stirring teeth 407 are both fixedly connected to the upper inner wall of the box body 1, and the box body 1 supports the two stirring teeth 407.

The upper left end of the baffle 501 is fixedly connected with a second spring 503. The baffle 501 is pressed against the second spring 503, and the elasticity of the second spring 503 enables the baffle 501 to fluctuate up and down with a certain elasticity to play a role in delaying the material discharge. The left end of the second spring 503 is fixedly connected to the lower left inner wall of the box body 1, and the box body 1 supports the two second springs 503. The upper part of the support plate 502 is movably connected to the middle inner wall of the turntable 504.

The baffle 501, the support plate 502, the second spring 503 and the turntable 504 are symmetrically distributed on the left and right sides with the center line of the box body 1 as the center.

[0020] The material discharging mechanism 6 includes a housing 601, a second motor 602, a first sheave 603, a belt 604, a second sheave 605, a spiral tooth 606 and a frame 607. The left end of the housing 601 is fixedly connected to the lower right end of the box body 1, and the box body 1 supports the housing 601. The left bottom inner wall of the housing 601 is fixedly connected with a second motor 602, and the housing 601 supports the second motor 602. The output shaft of the second motor 602 is rotationally connected to the first sheave 603, and the output shaft of the second motor 602 drives the first sheave 603 to rotate. The first sheave 603 is rotationally connected to the second sheave 605 through the belt 604, and the first sheave 603 drives the second sheave 605 to rotate through the belt 604. The middle outer wall of the belt 604 penetrates through the upper right inner wall of the housing 601, and the belt 604 is in clearance fit with the housing 601. The belt 604 rotates inside the housing 601. The middle outer wall of the second sheave 605 is sleeved with a spiral tooth 606, and the second sheave 605 drives the spiral tooth 606 to rotate. The right outer wall of the spiral tooth 606 sequentially penetrates through the lower right inner wall of the box body 1 and the right end middle inner wall of the frame 607, and the spiral tooth 606 is in clearance fit with both the box body 1 and the frame 607. The spiral tooth 606 rotates inside the box body 1 and the frame 607 to transport the falling material. The outer wall of the frame 607 is sleeved on the lower inner wall of the box body 1, and the box body 1 supports the frame 607. The right top end and the left end of the frame 607 are both connected to the box body 1. The falling material enters the frame 607 from the box body 1, and the material is discharged outside the box body 1 through the rotation of the spiral tooth 606. The first sheave 603 and the second sheave 605 are on the same vertical line, and the first sheave 603 drives the second sheave 605 to rotate stably.

[0021] When using the biomass gasification reactor with anti-blocking function, first, manually discharge the waste into the box body 1 from the top of the box body 1. Connect the external power supply of the first motor 401. The first motor 401 works, and the output shaft of the first motor 401 drives the first gear 403 to rotate. The meshing force between the first gear 403 and the second gear 404 drives the second gear 404 to rotate. The second gear 404 drives the rotating shaft 405 to rotate. The rotating teeth 406 rotate in the box body 1 through the rotating shaft 405. The rotating teeth 406 rotate and mesh with the two mixing teeth 407 to crush the waste, which is beneficial to improving work efficiency. The two mixing teeth 407 on both sides are stressed and simultaneously squeeze the two first springs 408, and the elasticity of the first springs 408 buffers the mixing teeth 407. The crushed waste falls between the two mixing teeth 407 and the two top plates 409. At this time, the external high-pressure steam enters the heating coil 9 through the inlet 10 and is discharged through the outlet 11 to form a heat cycle, performing high-temperature oxidation treatment on the falling waste. The treated ash-like substance continues to fall. At this time, the external condensed water enters the condensing pipe 3 through the water inlet 7 and is discharged through the water outlet 8 to form a condensation cycle, cooling the ash-like substance. The cooled ash-like substance falls and contacts the two turntables 504. The two turntables 504 rotate on the support plate 502 to slow down the falling speed of the ash-like substance. The ash-like substance contacts the two baffles 501. The baffles 501 rotate on the support plate 502 and squeeze the second springs 503, and the elasticity of the second springs 503 causes the baffles 501 to fluctuate up and down to also slow down the falling speed of the ash-like substance, preventing blockage of the discharge port. At this time, connect the external power supply of the second motor 602. The second motor 602 works, and the output shaft of the second motor 602 drives the first sheave 603 to rotate. The first sheave 603 drives the second sheave 605 to rotate through the belt 604. The second sheave 605 drives the spiral teeth 606 to rotate. The spiral teeth 606 rotate in the box body 1 and the frame 607 to transport the falling ash-like substance. The falling ash-like substance enters the frame 607 from the box body 1, and the spiral teeth 606 rotate to discharge the ash-like substance out of the box body 1.
