Description

Technical Field

[0001] The utility model relates to the technical field of furfural production, in particular to a waste residue recovery device for producing furfural from corn cobs. Background Art

[0002] Furfural is typically obtained through acid-catalyzed hydrolysis of pentose-rich agricultural waste, such as corncobs, sugarcane bagasse, and rice husks. Furfural is a key raw material for furan resin production, widely used in foundry, refractories, and coatings. Furfural production from corncobs leaves behind waste residue, which can be used to produce fertilizer. Therefore, recycling this waste residue can conserve resources.

[0003] For example, the patent document with the announcement number CN216297040U discloses a waste residue recovery device for producing furfural from corn cobs. The spiral blades are driven by a motor to rotate, and the spiral blades transport the waste residue in the separation cylinder. The waste residue is separated from the liquid during the movement in the separation cylinder, and then the waste residue is discharged through the discharge hopper. Since the waste residue has a certain water absorption capacity, if the waste residue is not squeezed but only moved in the separation cylinder, the discharged waste residue still contains a certain amount of liquid and still needs to be processed subsequently, resulting in an increase in the number of processes and difficulty in improving efficiency.

[0024] The present invention will be further described below with reference to the accompanying drawings:

[0025] like Figures 1-6As shown, a waste residue recovery device for producing furfural from corn cobs includes a support platform 1 and a separation mechanism 8. A separation box 2 and a pressing box 3 are fixed on the top of the support platform 1. The separation mechanism 8 is installed in the separation box 2. A feed hole 301 is provided on the side of the pressing box 3 close to the separation box 2. The discharge end of the separation mechanism 8 is connected with the pressing box 3 through the feed hole 301. The waste residue in the separation mechanism 8 enters the pressing box 3 after simple separation. A pressing block 4 is provided in the pressing box 3. The pressing block 4 moves downward to squeeze the waste residue in the pressing box 3, further separating the liquid in the waste residue. A baffle 401 is welded on the top of the pressing block 4. The baffle 401 is in contact with the inner wall where the feed hole 301 is located. 3 is slidably connected to a push block 5 at the bottom, and the push block 5 is used to push the pressed waste residue out of the pressing box 3. A filter screen 302 is fixed at the bottom of the pressing box 3. When the waste residue is pressed, the separated liquid flows down through the filter screen 302. A collecting bucket 9 is connected to the bottom of the support platform 1 by screws. The collecting bucket 9 is used to collect the liquid separated from the separation box 2 and the pressing box 3. The push block 5 is in contact with the top surface of the filter screen 302. A material port is provided on the rear side of the pressing box 3. A switch door assembly for closing and opening the material port is installed on the rear side of the pressing box 3. A lifting mechanism 6 for driving the pressing block 4 to move up and down is installed on the front side of the pressing box 3. A transmission mechanism 7 for driving the push block 5 to move forward and backward is provided on the front side of the push block 5.

[0026] The lifting mechanism 6 includes a fixed frame 601, which is connected to the front side of the pressing box 3 by screws. The bottom end of the fixed frame 601 is connected to the lifting motor 602 by bolts. The output shaft of the lifting motor 602 is connected to the screw rod 603 through a coupling. The screw rod 603 is connected to the fixed frame 601 through a bearing. The lifting frame 604 is threaded on the screw rod 603. The lifting frame 604 is slidably connected to the fixed frame 601. The lifting frame 604 is in an inverted U shape. The rear end of the lifting frame 604 is fixedly connected to the pressing block 4. The screw rod 603 is used to drive the lifting frame 604 to move up and down, so that the lifting frame 604 drives the pressing block 4 to move up and down.

[0027] The transmission mechanism 7 includes two supports 701, which are fixed to the top of the support platform 1 by screws. A gear column 702 is connected between the supports 701 through a bearing. A horizontal rack 703 is engaged at the bottom of the gear column 702. The rear end of the horizontal rack 703 is fixedly connected to the push block 5. A vertical rack 704 is engaged at the rear side of the gear column 702. A through hole is opened on the support platform 1 for avoiding the vertical rack 704. The top of the vertical rack 704 is fixedly connected to the front end of the lifting frame 604. When the vertical rack 704 moves downward, it drives the gear column 702 to rotate, and the gear column 702 drives the horizontal rack 703 to move forward, and the horizontal rack 703 drives the push block 5 to move forward. Therefore, when the pressing block 4 moves downward to press the waste residue, the push block 5 moves forward so that the separated liquid can flow down through the filter 302. When the rear side wall of the push block 5 coincides with the front inner wall of the pressing box 3, the pressing is completed, and then the pressing block 4 starts to move upward, and the push block 5 starts to move backward and pushes out the pressed waste residue.

[0028] The switch door assembly includes a cylinder 303, which is fixed to the rear side of the pressing box 3 by screws. The output shaft of the cylinder 303 is fixedly connected to a connecting block 304, and the connecting block 304 is fixedly connected to a lifting door 305, which is attached to the rear side wall of the pressing box 3.

[0029] The separation mechanism 8 includes a separation cylinder 801, which is fixedly connected to the inside of the separation box 2. The end of the separation cylinder 801 away from the pressing box 3 is connected to the separation motor 802 by bolts. The output shaft of the separation motor 802 is connected to the auger shaft 803 through a coupling. The auger shaft 803 is connected to the separation cylinder 801 through a bearing. The top of the end of the separation cylinder 801 away from the pressing box 3 is fixedly connected to the feed hopper 804. The separation cylinder 801 is connected to the pressing box 3 through the feed hole 301. When the pressing block 4 moves down a certain distance, the baffle 401 blocks the feed hole 301. At this time, the waste residue in the separation cylinder 801 cannot enter the pressing box 3. As the auger shaft 803 rotates, the waste residue will gather toward the feed hole 301, thereby pre-pressing the waste residue in the separation cylinder 801 to improve the waste residue separation effect.

[0030] A slide groove 101 is provided on the top of the support platform 1 , and a slider 501 is fixedly connected to the front side of the push block 5 . The slider 501 is slidably connected in the slide groove 101 . The slider 501 can make the push block 5 move more smoothly.

[0031] Working principle: When in use, the waste residue is poured from the feed hopper 804 into the separation cylinder 801, and the separation motor 802 drives the auger shaft 803 to rotate, and the auger shaft 803 transports the waste residue to the pressing box 3. During the movement of the waste residue in the separation cylinder 801, part of the liquid will flow down from the separation cylinder 801 and enter the collection bucket 9. The waste residue enters the pressing box 3 through the feed hole 301 and falls onto the push block 5. After a certain amount of waste residue accumulates in the pressing box 3, the pressing block 4 moves downward, and the lifting motor 602 drives the screw rod 603 to rotate, and the screw rod 603 is pushed down. The rod 603 drives the lifting frame 604 to move downward, and the lifting frame 604 drives the pressure block 4 to move downward. The pressure block 4 presses and separates the waste residue in the pressing box 3. The pressure block 4 drives the baffle 401 to move downward. The baffle 401 blocks the feed hole 301, so that the waste residue in the separation cylinder 801 cannot enter the pressing box 3. At this time, the rotation of the auger shaft 803 is still maintained, so that the waste residue in the separation cylinder 801 gathers to the feed hole 301, and the waste residue at the feed hole 301 is gradually squeezed, thereby realizing the pre-separation of the waste residue, which can improve the waste residue separation effect.

[0032] As the lifting frame 604 moves downward, it drives the vertical rack 704 downward, and the vertical rack 704 drives the gear column 702 to rotate. The gear column 702 drives the horizontal rack 703 to move forward, and the horizontal rack 703 drives the push block 5 to move forward, so that the liquid separated from the waste residue passes through the filter 302 and flows into the collecting bucket 9. When the rear side wall of the push block 5 coincides with the front inner wall of the pressing box 3, the pressing is completed, and then the pressing block 4 starts to move up and the push block 5 starts to move backward. At this time, the lifting door 305 is driven upward by the cylinder 303, so that the material port on the rear side of the pressing box 3 is opened, and the push block 5 moves backward to push out the pressed waste residue.

Those skilled in the art should understand that the present invention is not limited to the above embodiments. The above embodiments and descriptions are merely illustrative of the principles of the present invention.
