Description

Technical Field

[0001] This utility model relates to the field of bio-based material drying technology, and in particular to a laminar flow drying device for bio-based materials. Background Technology

[0002] Bio-based materials refer to materials made from biomass or produced through biotechnology. These include various materials prepared from biomass or through biosynthesis, bioprocessing, and biorefining processes. During the processing of bio-based materials, the raw materials need to be dried to facilitate subsequent processing. When drying bio-based materials, belt dryers are usually selected. Belt dryers use conveyor belts to continuously feed materials into the drying chamber for laminar flow drying.

[0003] In existing belt dryers, when bio-based materials are laminar dried, the bio-based materials are conveyed to the surface of the conveyor belt of the belt dryer by a conveying device, and then the bio-based materials undergo laminar flow drying inside the belt dryer. However, before being placed into the belt dryer, some bio-based materials often contain a lot of moisture, resulting in a long drying time for the bio-based materials inside the belt dryer. To address this, we propose a laminar flow drying device for bio-based materials. Utility Model Content

[0004] The main objective of this invention is to provide a laminar flow drying device for bio-based materials. A pre-drying mechanism is installed at the feed end of the belt dryer. The pre-collection box of the pre-drying mechanism has filter cartridges A and B for airflow. At the same time, the pre-collection box has upper and lower guide plates to guide the bio-based materials. Combined with the airflow generated by the fan, the bio-based materials can be pre-dried by airflow, which improves the drying efficiency, lays a good foundation for the subsequent laminar flow drying of bio-based materials, and shortens the drying time of bio-based materials in the belt dryer. This can effectively solve the problems in the background art.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] A laminar flow drying device for bio-based materials includes a belt dryer. The belt dryer has an outwardly extending conveyor belt installed inside its casing. It also includes a pre-drying mechanism, which comprises L-shaped supports, a pre-collection box, an upper guide plate, a lower guide plate, a guide pipe, filter cartridge A, filter cartridge B, a fan, and a vibrating motor. L-shaped supports are symmetrically installed on the casing surface of the belt dryer at the feed end, and a pre-collection box for pre-collecting bio-based materials is fixed to the surface of the L-shaped supports. The upper and lower guide plates are staggered and welded from top to bottom inside the pre-collection box. A guide pipe extending towards the conveyor belt is welded to the bottom of the pre-collection box below the upper guide plate. Filter cartridges A and B for air passage are symmetrically installed on the two side panels of the pre-collection box, and a fan is installed outside the pre-collection box on the side of filter cartridge B. A vibrating motor is installed at the bottom of the pre-collection box below the lower guide plate.

[0007] Furthermore, a vertical connecting plate is welded to the bottom end of the pre-receiving box below the lower guide plate, and a vibration motor is bolted to the surface of the vertical connecting plate;

[0008] By adopting the above technical solution, a vibration motor can be installed at the bottom of the pre-collection box below the lower guide plate via a vertical connecting plate to provide vibration. This allows the pre-collection box to obtain vibration through the vibration motor, enabling the bio-based material inside the pre-collection box to quickly fall into the guide pipe for discharge.

[0009] Furthermore, the pre-receiving box has symmetrical mounting holes on both sides of the box panel, and filter cylinder A and filter cylinder B are screwed into the mounting holes;

[0010] By adopting the above technical solution, the pre-collection box can be screwed on with filter cartridges A and B through the mounting holes for filtration ventilation.

[0011] Furthermore, filter screens are fixed inside the cylinders of filter cylinders A and B, and the openings of filter cylinders A and B face between the upper guide plate and the lower guide plate.

[0012] By adopting the above technical solution, the filter screen inside filter cylinders A and B can intercept external debris from entering the pre-collection box. When the wind generated by the fan at filter cylinder B enters the pre-collection box, the wind can pre-dry the bio-based material that has passed through the upper and lower guide plates.

[0013] Furthermore, the upper guide plate is inclined toward the lower guide plate, and the lower guide plate is inclined toward the guide tube.

[0014] By adopting the above technical solution, when the bio-based material enters the pre-receiving box, the bio-based material can fall from the upper guide plate to the lower guide plate, and at the same time, the bio-based material on the surface of the lower guide plate can be guided to fall into the guide tube for discharge.

[0015] Furthermore, L-shaped support feet are symmetrically welded to the bottom of the pre-collection boxes on both sides of the guide pipe, and the foot plates of the L-shaped support feet are locked to the surface of the feed end box of the belt dryer by bolts.

[0016] By adopting the above technical solution, the L-shaped support legs at the bottom of the pre-collection box can be installed at the feed end of the belt dryer, thereby providing support for the pre-collection box.

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] This invention features a pre-drying mechanism installed at the feed end of a belt dryer. The pre-collection box of the pre-drying mechanism has filter cartridges A and B for airflow. Simultaneously, the pre-collection box contains upper and lower guide plates to guide the falling bio-based material. Combined with the airflow generated by the fan, the bio-based material can be pre-dried by airflow, improving drying efficiency and laying a good foundation for subsequent laminar flow drying of the bio-based material, thus shortening the drying time of the bio-based material in the belt dryer.

[0019] Furthermore, the vibration motor below the pre-collection box provides stable vibration, which promotes the rapid and uniform falling of bio-based materials into the guide pipe, avoiding the accumulation and blockage of materials in the pre-collection box and ensuring a continuous and stable drying process.

[0025] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0026] like Figure 1-4 As shown, a laminar flow drying device for bio-based materials includes a belt dryer 1. A conveyor belt 2 extending outwards is installed inside the casing of the belt dryer 1. It also includes a pre-drying mechanism 3, which comprises L-shaped supports 4, a pre-collection box 5, an upper guide plate 6, a lower guide plate 7, a guide pipe 8, filter cartridges A10 and B11, a fan 12, and a vibrating motor 14. L-shaped supports 4 are symmetrically installed on the casing surface of the belt dryer 1 on the feed end side, and the surfaces of the L-shaped supports 4 are fixed... A pre-collection box 5 is provided for pre-collecting bio-based materials. Inside the box 5, an upper guide plate 6 and a lower guide plate 7 are welded in a staggered manner from top to bottom. A guide pipe 8 extending to the conveyor belt 2 is welded to the bottom of the pre-collection box 5 below the upper guide plate 6. Filter cartridges A10 and B11 for air passage are symmetrically installed on the two side panels of the pre-collection box 5. A fan 12 is installed on the outside of the pre-collection box 5 on the side of filter cartridge B11. A vibration motor 14 is installed at the bottom of the pre-collection box 5 below the lower guide plate 7.

[0027] Among them, a vertical connecting plate 13 is welded to the bottom end of the pre-receiving box 5 below the lower guide plate 7, and a vibration motor 14 is locked to the surface of the vertical connecting plate 13 by bolts.

[0028] By adopting the above technical solution, a vibration motor 14 can be installed at the bottom of the pre-collection box 5 below the lower guide plate 7 via a vertical connecting plate 13 to provide vibration, so that the pre-collection box 5 can obtain vibration through the vibration motor 14, and the bio-based material in the pre-collection box 5 can quickly fall into the guide pipe 8 for discharge.

[0029] The pre-receiving box 5 has symmetrical mounting holes 9 on both sides of the box plate, and filter cylinder A10 and filter cylinder B11 are screwed into the mounting holes 9.

[0030] By adopting the above technical solution, the pre-receiving box 5 can be screwed on with filter cartridges A10 and B11 through the mounting hole 9 for filtration ventilation.

[0031] The filter cylinders A10 and B11 are equipped with filter screens, and the openings of the filter cylinders A10 and B11 face between the upper guide plate 6 and the lower guide plate 7.

[0032] By adopting the above technical solution, the filter screen inside the filter cylinders A10 and B11 can intercept external debris from entering the pre-collection box 5. When the wind generated by the fan 12 enters the pre-collection box 5 at the filter cylinder B11, the wind can pre-dry the bio-based material that has passed through the upper guide plate 6 and the lower guide plate 7.

[0033] The upper guide plate 6 is inclined toward the lower guide plate 7, and the lower guide plate 7 is inclined toward the guide tube 8.

[0034] By adopting the above technical solution, when the bio-based material enters the pre-receiving box 5, the bio-based material can fall down to the lower guide plate 7 along the upper guide plate 6, and at the same time, the bio-based material on the surface of the lower guide plate 7 can be guided to fall into the guide pipe 8 for discharge.

[0035] Among them, L-shaped support legs 4 are symmetrically welded to the bottom of the pre-collection box 5 on both sides of the guide pipe 8, and the foot plates of the L-shaped support legs 4 are locked to the surface of the feed end box of the belt dryer 1 by bolts.

[0036] By adopting the above technical solution, the L-shaped support 4 at the bottom of the pre-collection box 5 can be installed at the feed end of the belt dryer 1, thereby providing support for the pre-collection box 5.

[0037] It should be noted that this utility model is a laminar flow drying device for bio-based materials. A pre-drying mechanism 3 is set at the casing on one side of the feed end of the belt dryer 1. The pre-collection box 5 of the pre-drying mechanism 3 is installed at the casing on one side of the feed end of the belt dryer 1 with the aid of L-shaped support legs 4. Filter cartridges A10 and B11 can be screwed onto the mounting holes 9 on both sides of the pre-collection box 5. At the same time, the fan 12 can be installed outside the pre-collection box 5, and the vibration motor 14 is installed at the vertical connecting plate 13 below the pre-collection box 5. The fan 12 and the vibration motor 14 can be electrically connected to an external controllable power supply for control. When the bio-based material is sent to the belt dryer by the conveying equipment... Before drying at conveyor belt 2, the bio-based material can be introduced into the pre-collection box 5. The bio-based material can fall down the upper guide plate 6 to the lower guide plate 7. At the same time, the bio-based material on the surface of the lower guide plate 7 can be guided to fall into the guide pipe 8 for discharge. When the air force generated by the fan 12 at filter cylinder B11 enters the pre-collection box 5, the air force can blow pre-dry the bio-based material that has passed through the upper guide plate 6 and the lower guide plate 7. After pre-drying, the bio-based material enters the belt dryer 1 under the drive of conveyor belt 2 for laminar flow drying and then is discharged. The pre-dried bio-based material can carry away moisture, shortening the drying time of the bio-based material in the belt dryer 1.
