[0018] 2.

[0019] 3. The present invention opens two sealing baffles at the same time by setting a rotating component. When the connecting cross frame drives the L-shaped connecting rod to move a certain distance, it is in the process of squeezing the slag to exhaust the gas. Rack three contacts gear three. The L-shaped connecting rod continues to move and drives gear three to rotate through rack three. The two sealing baffles are driven to rotate a certain angle through the transmission structure, so that the slag after the gas is squeezed out is quickly discharged, reducing the downtime of the equipment, thereby improving the operation efficiency of the entire production process, and preventing the separated slag from being retained in the equipment for a long time, which may cause part of the separated residual gas to be mixed with the slag again, affecting the separation effect.

[0020] 4. The present invention quickly extracts the extruded gas from the box body by arranging an exhaust component. The gas squeezed out from the slag enters the annular ventilation hood through the air outlet groove and the exhaust groove, and is then discharged through the vacuum pump, making the collection of the separated gas more convenient, which not only helps to improve the gas recovery rate, but also can reduce pollution emissions and achieve the effect of protecting the environment.

The pressure plate 41 is fixedly connected, and a transmission gear 456 is respectively meshed between the two pushing racks 451 and the pulling rack 452. When the transmission gear 456 rotates, it drives the pushing rack 451 and the pulling rack 452 to move in opposite directions at the same time, and at the same time pushes the two movable pressure plates 41 to move toward the middle, and then squeezes out the gas in the furfural slag. A servo drive 454 is fixedly installed on one side of the interior of the box body 1. The servo drive 454 can be set as a cylinder, and a connecting cross frame 455 is fixedly set on the output shaft of the servo drive 454.

[0043] A transmission horizontal shaft 457 is fixed between the two transmission gears 456, and the two ends of the transmission horizontal shaft 457 respectively penetrate the two partition baffles 3 and are rotatably connected thereto through bearings. A rack 458 is fixed to the bottom of one end of the connecting cross frame 455, and a gear 459 is meshed at the bottom of the rack 458, and one end of the transmission horizontal shaft 457 extends to be fixedly connected to the gear 459. When the connecting cross frame 455 moves, the gear 459 is driven to rotate by the rack 458, and the gear 459 drives the transmission gear 456 to start rotating through the transmission horizontal shaft 457. A strip slide groove is provided on one side of the connecting cross frame 455, and a limit block 450 fixed to one of the partition baffles 3 is slidably provided on the inner side of the strip slide groove, and the connecting cross frame 455 slides on the outer side of the limit block 450, so that the movement of the connecting cross frame 455 is more stable.

The gear set 445 can be arranged as a bevel gear set 445 or a worm gear set 445, etc. When the horizontal axis 2 444 rotates, it drives the horizontal axis 1 442 to rotate. A gear 2 446 is fixed to the end of the horizontal axis 2 444 away from the horizontal axis 1 442, and a rack 2 447 is meshed with the top of the gear 2 446 and fixed to the other end of the connecting horizontal frame 455.

[0046] When the connecting cross frame 455 moves, it drives the rack 2 447 to move, the rack 2 447 drives the gear 2 446 meshing with it to rotate, the gear 2 446 drives the horizontal shaft 2 444 to rotate, the horizontal shaft 2 444 drives the horizontal shaft 1 442 to rotate through the gear set 445, and the horizontal shaft 1 442 drives the stirring impellers 443 at both ends to rotate, so as to turn the extruded furfural slag up and down, to prevent the gas squeezed out of the slag accumulated at the bottom from being difficult to be discharged quickly, which causes part of the separated residual gas to be re-mixed with the slag, affecting the separation effect.

[0047] Third embodiment

[0048] In order to quickly discharge the slag after extrusion and exhaust gas, and improve the operating efficiency of the entire production process, such as Figure 3 and Figure 8As shown, in this embodiment, a rotating assembly 46 for simultaneously driving and rotating two sealing baffles 42 to discharge furfural slag is provided on one side of the box body 1.

The positioning shaft 467 is supported for rotation, and a transmission belt 468 is arranged between the positioning shaft 467 and the rotating horizontal shaft 461 with the gear three 462 at the end thereof through a pulley transmission.

[0049] Arc-shaped grooves are respectively provided on the surfaces of both ends of the two partition baffles 3, and limiting columns 469 that slide with the arc-shaped grooves are respectively fixedly provided on both sides of the sealing baffle 42. When the sealing baffle 42 rotates, the limiting columns 469 are driven to rotate inside the arc-shaped grooves, so that the rotation of the sealing baffle 42 is more stable, while limiting the rotation angle of the sealing baffle 42 to prevent the sealing baffle 42 from being crushed by furfural residue when it rotates.

[0051] The present invention first pushes the two movable pressure plates 41 toward the middle to extrude the furfural slag through the moving component 45, and at the same time cooperates with the turning component 44 to turn over the furfural slag to quickly discharge the extruded gas, and at the same time the extruded gas is quickly extracted from the box body 1 through the exhaust component 5, and then the two sealing baffles 42 are opened at the same time through the rotating component 46, so that the slag after the gas is squeezed and exhausted is quickly discharged, which not only enhances the separation effect of furfural gas and slag, but also improves the separation efficiency of the separation equipment.

[0052] In actual use of the separation device, furfural residue is added to the separation bin 43 in the box body 1 through the feed hopper 2, and then the feed hopper 2 is closed, and then the servo drive 454 is started, and the output shaft of the servo drive 454 pulls the connecting cross frame 455 to move, and the connecting cross frame 455 first drives the rack 458 at the bottom of one end thereof to move, and the rack 458 drives the gear 459 meshing with it to rotate, and the gear 459 drives the transmission horizontal shaft 457 at its axis to rotate, and the transmission horizontal shaft 457 drives The transmission gears 456 at both ends start to rotate.

[0054] When rack one 458 and gear one 459 are completely disengaged, the connecting cross frame 455 drives rack three 465 to move through the L-shaped connecting rod 464, and rack three 465 drives gear three 462 meshing therewith to rotate, and gear three 462 drives the rotating horizontal shaft 461 at its axis to rotate, and the rotating horizontal shaft 461 drives the transmission belt 468 to operate through the pulley, and one end of the transmission belt 468 drives the positioning shaft 467 to rotate through the pulley, and the positioning shaft 467 drives the driving gear 466 thereon to rotate, and the driving gear 466 drives the driven gear 463 meshing therewith to rotate, and the driven gear 463 drives another rotating horizontal shaft 461 to rotate, so that the two rotating horizontal shafts 461 rotate in opposite directions at the same time, so that the sealing baffle 42 is fully opened, so that the slag after the gas is squeezed and discharged is quickly discharged through the discharge plate 5.
