Description

Technical Field

[0001] The utility model relates to the technical field of recycling and processing equipment, in particular to a waste residue separation device for furfural production. Background Art

[0002] Furfural is an important organic chemical raw material widely used in synthetic plastics, pharmaceuticals, pesticides, fragrances, and other fields. Therefore, research on furfural production methods is crucial for improving its production efficiency and quality. This article will introduce furfural production methods, including raw material preparation, reaction process, and post-processing, and analyze the key factors affecting furfural yield and quality. Furfural residue, a waste generated during biomass hydrolysis, is high in salt and acidic. Its accumulation can pollute the atmosphere, soil, and rivers. As a biomass waste, furfural residue contains significant amounts of cellulose, hemicellulose, and lignin, offering excellent recycling potential. Therefore, the rational resource utilization of furfural residue, eliminating its environmental impact, increasing its economic value, achieving zero pollutant emissions in furfural production processes, and achieving clean production and recycling are urgent challenges in the resource utilization of furfural residue. Key areas of resource utilization for furfural residue include the production of porous adsorbent carbon materials, alkaline soil improvement, soil remediation in mining areas, crop cultivation, and chemical processing. Furfural residue is rich in vitamins, lignin, and a small amount of sulfuric acid. The comprehensive utilization of these organic substances can transform waste into valuable resources. Its application is primarily concentrated in agriculture. Separating waste residue in furfural production can improve waste utilization, save costs, and avoid environmental waste. However, a common type of furfural production waste residue separation device suffers from long separation cycles and turnover times, hindering rapid processing in furfural production.

[0014] The present invention will be further explained below with reference to the accompanying drawings and specific embodiments.

[0015] Embodiment: As shown in the figure, the waste residue separation device for furfural production described in the utility model includes a frame 1, which is fixed on the ground. The top of the frame 1 is connected to a vibrating screen 2, and the upper front end of the vibrating screen 2 is also provided with a feeding mechanism 3 for loading. The vibrating screen 2 includes side panels 4, vibrating connectors 5, driving members 6, sieve plates 7 and guide plates 8. Vibrating connectors 5 connected to the frame 1 are installed at both ends of the outer sides of the side panels 4. The sieve plates 7 at the top and the guide plates 8 at the bottom are fixedly connected between the two side panels 4. The middle part of the side panel 4 is provided with a driving member 6, which is driven by an external drive to drive the driving member 6 to move eccentrically, so that the vibrating screen 2 moves. The tail of the side panel 4 is also provided with a guiding mechanism 9, and the guiding mechanism 9 is electrically connected to the external drive. During use, the waste will pass through the discharge mechanism 3 and fall onto the sieve plate 7. After screening, small particles will be discharged through the guide plate 8 at the bottom, and large particles will be discharged through the surface of the sieve plate 7. After the two are separated, they can be recycled after chemical or biological harmless treatment.

[0016] The drainage mechanism 9 includes a support frame 10 fixed to the frame 1. A clamping member 11 is mounted on the top of the support frame 10. A bearing seat 12 is connected to the inner portion of the clamping member 11. A rotating shaft 13 is rotatably connected to the inner portion of the bearing seat 12. The rotating shaft 13 is connected to an external drive. A group of circumferentially distributed guide rods 14 are also provided on the outer edge of the rotating shaft 13. During use, the external drive drives the rotating shaft 13 to rotate, causing the rotating shaft 13 to rotate on the clamping member 11, thereby driving the guide rods 14 to rotate. The support frame 10 is fixed to the frame 1. The movement of the vibrating screen 2 does not affect the movement of the drainage mechanism 9. The two can control their respective movements to separate the waste.

[0017] The unloading mechanism 3 includes a bracket 15, a reinforcement frame 16, and a silo 17. The lower end of the silo 17 is open and located directly above the vibrating screen 2. The lower end of the silo 17 is supported by the fixed bracket 15, and the reinforcement frame 16 is fixed between the brackets 15. The silo 17 is used to store waste. When in operation, the opening is opened to allow the waste to fall onto the vibrating screen 2 for screening. When not screening, the silo 17 can be used as a container for storing waste.

[0018] The guide rod 14 is also provided with a chute, and a baffle 18 is connected between the chute. The baffle 18 is fixed to the guide rod 14 by bolts, and the position of the baffle 18 on the chute can be changed by the bolts. During use, the height of the bolt on the chute can be changed by loosening or tightening the bolt, thereby adjusting the height of the baffle 18 on the guide rod 14, that is, adjusting the distance between the lower end of the baffle 18 and the screen plate 7. This facilitates controlling the thickness of the waste passing through the drainage mechanism 9, causing repeated vibration separation, and improving separation efficiency.

[0019] Baffle 18 is provided with a set of through-holes, and a gap is provided between the lower end of baffle 18 and the lowest point of guide rod 14 for material to pass through. During use, the gap is used to pass waste material, and baffle 18 is used to block the passage of waste material, preventing it from accumulating too thickly and being mixed with other debris. The blocking effect of baffle 18 can limit waste material that exceeds baffle 18 to the baffle 18, slowing its passage speed and increasing the vibration duration, thereby improving the separation effect.

[0020] The utility model stores furfural waste residue through a feeding mechanism. After the feeding material enters the vibrating screen, it is vibrated and separated to separate substances of different masses. The fine particles pass through the screen plate and fall into the guide plate. The lighter cellulose is discharged from the surface after being screened multiple times on the screen plate surface. During the process, the guiding mechanism will block the waste on the screen plate surface to a certain height, thereby increasing the vibration time on the screen plate surface, thereby improving the separation effect, reducing the repeated screening cycle and time, and improving the separation efficiency. The structure is simple and easy to use.

[0021] The above description is only used to illustrate the technical solution of the present invention and is not intended to limit it. Other modifications or equivalent substitutions made to the technical solution of the present invention by ordinary technicians in this field should be included in the scope of the claims of the present invention as long as they do not depart from the spirit and scope of the technical solution of the present invention.
