The first driving groove 609 and the second driving groove 610 are arranged crosswise. Two ends of the first return groove 611 are respectively connected to the first end of the first driving groove 609 and the second end of the second driving groove 610. Two ends of the second return groove 612 are respectively connected to the first end of the second driving groove 610 and the second end of the first driving groove 609. A shuttle-shaped guide block 613 is rotatably mounted on the driving shaft 614. The shuttle-shaped guide block 613 is slidably engaged in the first driving groove 609. Baffles are mounted in the first end of the first driving groove 609, the first end of the second driving groove 610, the second end of the first return groove 611 and the second end of the second return groove 612.

By providing the condensate plate flipping assembly 6 and two L-shaped condensate plates 508 and side condensate plate 509, after the condensate plate assembly 5 sinks, the condensate surface can be rotated and replaced, and the condensate surface with condensate oil attached can be erected to promote the flow of condensate oil by gravity. And in both states of the condensate plate assembly 5, a condensate channel can be formed by surrounding on three sides, improving the condensate effect.

[0031] As Figure 2 、 Figure 3As shown, the rotary drive assembly 7 includes a crossbar 701, a main shaft 706, a turntable 704, a coil spring 711 and a one-way drive assembly 712. The crossbar 701 is fixedly installed in the support tube 3, the main shaft 706 is fixedly installed in the support tube 3, the turntable 704 is rotatably installed in the support tube 3, and a gear 707 and a one-way gear 708 are coaxially fixedly installed on the main shaft 706. The one-way gear 708 can be connected to the main shaft 706 by installing a one-way bearing in a conventional gear, so that the one-way gear 707 is fixedly installed on the main shaft 706. 8 can only transmit power to the main shaft 706 in one direction, and can also use a ratchet mechanism to transmit power. A toothed disc 705 is coaxially fixedly installed on the bottom wall of the rotating disc 704, and the toothed disc 705 is meshed with the gear 707. Two or more inclined slots 710 are opened on the rotating disc 704 along the circumferential direction. A hinged rod 709 is hinged on the inner wall of the support tube 3, and the end of the hinged rod 709 is inserted into the inclined slot 710; a rack 702 is slidably connected to the cross bar 701, and the rack 70 2 is meshed with the one-way gear 708, a connecting plate is fixedly connected to the top of the rack 702, a seesaw 506 is fixedly connected to the end of the connecting plate 502, the end of the seesaw 506 abuts against the bottom wall of the connecting plate, a pressure plate 507 is fixedly connected to the side wall of the seesaw 506, the end of the pressure plate 507 abuts against the top wall of the connecting plate, and a counterweight is fixedly connected to the bottom end of the rack 702; one end of the coil spring 711 is fixedly connected to the rotating disk 704, and the other end of the coil spring 711 is fixedly connected to the rotating disk 704. It is fixedly connected to the one-way drive component 712, and the one-way drive component 712 is coaxially installed on the rotating disk 4. The coil spring 711 is transmission-connected to the rotating disk 4 via the one-way drive component 712. By setting the rotating drive component 7, during the continuous condensation process, due to the increase of condensed oil on the condensation plate component 5, the weight of its end rises and sinks, thereby realizing the storage of rotational potential energy. Under certain conditions, the condensation plate component 5 is driven to rotate, thereby throwing away the condensed oil on its surface, so that the condensation plate component 5 can continue to work.

[0032] like Figure 9 , Figure 10As shown, the one-way driving assembly 712 includes a rotating ring 713 and a ratchet ring 714. The rotating ring 713 is rotatably mounted on the rotating disk 4, and the ratchet ring 714 is fixedly mounted on the rotating disk 4. A ratchet 715 is hinged on the side wall of the rotating ring 713, and the ratchet 715 is lapped on the ratchet ring 714. An installation cavity 716 is formed in the rotating ring 713, and a connecting rod 717 is installed in the installation cavity 716. The middle part of the connecting rod 717 is rotatably connected to the inner wall of the installation cavity 716. A locking tooth 720 is coaxially and fixedly installed in the support pipe 3. An opening communicating with the installation cavity 716 is formed in the side wall of the rotating ring 713. A catch 719 is hinged on the side wall of the opening. The end of the catch 719 contacts the locking tooth 720. A pull rod 721 is hinged on the top of the catch 719, and the other end of the pull rod 721 is hinged to the top end of the connecting rod 717. A weight 718 is fixedly connected to the bottom end of the connecting rod 717. A pressing rod 722 is hinged on the bottom of the rotating ring 713. A reset spring 723 is fixedly connected to the middle part of the pressing rod 722, and the other end of the reset spring 723 is fixedly connected to the bottom of the rotating ring 713. An annular groove is formed in the middle part of the rack 702 along its circumferential direction. The end of the pressing rod 722 is inserted into the annular groove. A push rod 724 is fixedly connected to the middle part of the pressing rod 722, and the other end of the push rod 724 is inserted into the installation cavity 716 and is close to the weight 718.

[0033] As Figure 3 , Figure 4 As shown, one end of the support frame 503 away from the rotating disk 4 is hinged with a liquid collecting hopper 8 through a support rod. The liquid collecting hopper 8 is fixedly connected to the support rod. The liquid collecting hopper 8 is located below one end of the L-shaped condensation plate 508 away from the rotating disk 4. A valve 801 is arranged at the bottom of the liquid collecting hopper 8. A top rod 802 is fixedly connected to the valve 801. The top end of the top rod 802 is close to the support frame 503. A limiting block is arranged on the side wall of the support frame 503 above the top rod 802. By arranging the liquid collecting hopper 8, the condensed oil can be stored, and the gravity for pressing down the condensation plate assembly 5 and the inertia of rotation can be provided, increasing the rotation duration and promoting the separation of the condensed oil.

[0034] Working process: During condensation, set the number of condensation layers and the temperature required for condensation as needed; introduce a cooling medium into the rotary joint 512, and the cooling medium enters the cooling flow channel 510. After the pyrolysis gas passes through, condensation is achieved; in order to improve the condensation effect of each stage, multiple condensation devices can be arranged in a staggered manner up and down.

[0035] As Figure 1As shown, the pyrolysis gas moves upward in the condensation pipe 1. After contacting the condensation plate assembly 5, condensation is achieved. After a certain amount of biomass oil adheres to the condensation plate assembly 5, the original balance is disrupted, and the end of the condensation plate assembly 5 equipped with the liquid collecting hopper 8 tilts downward, as Figure 2-4 shown. After the condensation plate assembly 5 tilts downward, it drives the rocker 506 to rotate upward and push the connecting plate upward, causing the rack 702 to move upward. The main shaft 706 and the gear 707 are driven to rotate through the one-way gear 708. The gear 707 drives the toothed disc 705 and the turntable 704 to rotate, as Figure 2 shown. Since the inclined card slot 710 is formed on the turntable 704 and cooperates with the articulated rod 709, the turntable 704 can only rotate in one direction, that is, the coil spring 711 is tightened. As the end of the condensation plate assembly 5 continuously moves downward, the coil spring 711 is continuously tightened, and the one-way drive assembly 712 at the other end of the coil spring 711 keeps the coil spring 711 in an energy storage state;

[0036] As Figure 3 and Figure 9 shown, when the rack 702 is continuously moving upward, it will drive the end of the pressing rod 722 to move upward through the annular groove, push the weight 718 to move to one side through the push rod 724, cause the connecting rod 717 to rotate, and pull the hook 719 to separate from the tooth 720 through the pull rod 721. The rotating ring 713 is in a freely rotatable state. After the rotational force of the coil spring 711 is applied to the rotating ring 713, it is transmitted to the rotating disc 4 through the ratchet ring 714 and the ratchet 715, so that the rotating disc 4 drives the condensation plate assembly 5 to rotate, and the condensed oil is thrown out onto the inner wall of the condensation pipe 1 by centrifugal force. An annular liquid collecting groove can be provided on the inner wall of the condensation pipe 1 to collect the condensed oil; when the rotational force of the coil spring 711 is completely released, the rotating disc 4 continues to rotate under the action of inertia. As the condensed oil on the condensation plate assembly 5 is continuously separated, the condensation plate assembly 5 gradually pulls the rack 702, the rocker 506 and the condensation plate assembly 5 to reset under the action of the counterweight. Since the one-way gear 708 can only transmit power in one direction, when the rack 702 resets, the one-way gear 708 cannot drive the main shaft 706 to rotate;

[0037] The hinge joint between the middle of the connecting rod 717 and the installation cavity 716 adopts a damping connection, so that the connecting rod 717 has a certain time delay when resetting, which can make the hook 719 connect with the tooth 720 with a time delay and increase the rotation time of the rotating disc 4;

[0038] As Figure 4 shown, when the condensation plate assembly 5 rotates, the liquid collecting hopper 8 swings outward under the action of inertia. At the same time, the ejector rod 802 abuts against the limit block on the side wall of the support frame 503, and the ejector rod 802 pushes open the valve 801, and the condensed oil in the liquid collecting hopper 8 is thrown out;

[0039] As Figure 4 、Figure 7 and Figure 8 As shown, during the downward rotation of the support frame 503, the push plate 602 will be squeezed and rotated, and at the same time, the second spring 605 is squeezed. Under the action of the fixed rod 607, the driving cylinder 603 cannot slide until the push plate 602 is pressed to the limit position to push the driving rod 606 to move inward. Under the action of the inclined groove 608, the fixed rod 607 is lifted upward, and the driving cylinder 603 slides into the mounting hole 511 under the action of the second spring 605, as Figure 8 shown, the shuttle-shaped guide block 613 and the driving shaft 614 move in the first driving groove 609 to rotate the rotating shaft 504 by 90°, as Figure 4 shown, under the action of the two synchronous tooth sectors 505, the two L-shaped condensation plates 508 are changed from Figure 5 the mating state to Figure 6 the mating state. When the condensation plate assembly 5 is reset, the shuttle-shaped guide block 613 moves to the first reset groove 611 and is reset under the action of the first spring 604. The elastic force of the first spring 604 is less than the elastic force of the second spring 605. When moving next time, the shuttle-shaped guide block 613 enters the second driving groove 610 to reverse the rotating shaft 504 by 90°.
