Description

Technical Field

[0001] This utility model belongs to the field of fiberboard processing technology, and in particular relates to a fiberboard raw material air washing device. Background Technology

[0002] Fiberboard is a type of engineered wood product made from wood fibers or other plant fibers through processes such as fiber separation, gluing, drying, assembling, and hot pressing. In the production and processing of fiberboard, the raw materials for fiber extraction mainly come from forest logging residues, such as branches, tips, and small-diameter timber, as well as wood processing residues, such as board edges, shavings, and sawdust. Before fiber separation, the raw materials are chipped using a chipper, then screened to separate large wood chips, removing small stones, metal, sand, and other impurities. The qualified wood chips are then fed into a hot mill for steaming and softening before fiber separation.

[0003] To ensure the purity of fiberboard raw materials, they must undergo essential cleaning steps after initial treatment. These typically involve two different systems and methods: water washing and air washing. While water washing achieves a high cleaning rate, it generates a large amount of wastewater, requiring significant investment and incurring high costs for wastewater treatment. Existing conventional air washing processes only separate the raw materials from impurities such as stones; they cannot effectively classify and export raw materials of different specifications after air washing. This impacts the work process to some extent, limits functionality, and fails to meet usage requirements. Utility Model Content

Located below the conveying plate, the box contains a partition, a limit plate at the lower end of the partition, a flow divider on one side of the limit plate, a first discharge hood below the box between the air pipe and the flow divider, a semi-circular guide plate inside the box on one side of the partition, a grading plate below the guide plate, and a conical collecting hood on the other side below the box. A second and a third discharge hood are respectively located at the lower end of the collecting hood, corresponding to the two sides of the grading plate.

[0006] Preferably, a guide plate is provided in the box located below one side of the distributor. The distributor includes a frame with a herringbone shape, arc grooves on both sides of the frame, and a material drop chute in the frame.

[0007] Preferably, the conveyor plate is provided with a diversion plate, which is arranged in an inclined manner from the geometric center near the conveyor plate. Multiple diversion plates are arranged in a mirror image about the geometric center of the conveyor plate. The air blowing pipe is designed with a tapered opening from top to bottom. Multiple air distribution plates are provided at the end of the air blowing pipe in an inclined manner, and are designed with a tapered opening from the side near the diversion plate.

[0008] Preferably, the grading plate includes a plate body with an obtuse angle design, the lower end of the plate body is placed inside the collection hood, and the collection hood is divided into left and right feeding areas, and a filter plate is provided in the upper half of the plate body.

[0017] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0018] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0019] Examples, such as Figures 1-4As shown, a fiberboard raw material air washing device includes an air washing device body, which includes a support frame 1 to ensure the stability of the device and ensure the smooth operation of production and processing. A box 2 is provided above the support frame 1, and a feed inlet 21 is provided on one side of the box 2. The feed inlet 21 protrudes from the box 2 and is used to receive the fiberboard raw material after initial processing to ensure the smooth operation of subsequent air washing. A distributor 3 is provided inside the feed inlet 21, and a conveying plate 4 is provided below the distributor 3 in an inclined arrangement. The distributor 3 and the conveying plate 4 work together to evenly distribute the raw material input into the box 2, ensure its falling speed, prevent material accumulation, and ensure the smooth operation of air washing.Furthermore: A fan 5 is installed above the housing 2, and an air conveying pipe 6 is installed at the output end of the fan 5. The air conveying pipe 6 passes around the outside of the housing 2 and goes to the bottom of the housing 2. An air blowing pipe 7 is installed inside the housing 2 at the bottom, and is located below the material conveying plate 4. The fan 5 generates air-washing spray gas, which acts on the inside of the housing 2 through the air conveying pipe 6, especially on the path of the falling material, thereby blowing the fiberboard raw material. At the same time, impurities such as stones or metals of a certain weight are not blown away but fall downwards and are discharged. A partition 8 is installed inside the housing 2, and a limit plate 91 is installed at the lower end of the partition 8. The limit plate 91... A diversion plate 10 is provided on one side. This design allows the material to be discharged through the gap between the limiting plate 91 and the diversion plate 10 after the gas discharged through the air pipe 7 acts on the material, thus ensuring the working process. A first discharge hood 11 is provided below the box 2 located between the air pipe 7 and the diversion plate 10. This design is mainly for discharging large debris such as stones or metals to prevent them from mixing with the raw materials for fiberboard preparation and affecting the subsequent output of fiberboard materials, thus ensuring the working process. A semi-circular guide plate 12 is provided inside the box 2 located on one side of the partition plate 8. The guide plate 12 guides the raw materials after air washing to ensure the air washing effect. Below the guide plate 12, a grading plate 13 is provided. On the one hand, it can wash out a large batch of raw materials for making fiberboard, and on the other hand, it can separate out fine particles or powder mixed in with the fiberboard raw materials to prevent them from affecting the subsequent processing and preparation of fiberboard, ensuring the forming quality of the workpiece and meeting the usage requirements. On the other side of the lower part of the box 2, a cone-shaped material collection hood 14 is provided. The lower end of the material collection hood 14 is respectively provided with a second discharge hood 141 and a third discharge hood 142, which are connected to the grading plate 12. Corresponding to the two sides of area 3, the second discharge hood 141 is mainly used to collect most of the raw materials for fiberboard preparation and output them to the external conveying equipment, such as a conveyor belt, so as to guide the materials to the outside. The third discharge hood 142 is mainly used to collect the fine particles or fiber powder filtered after the filter plate 132, so as to reduce their impact on the preparation and processing of fiberboard. It can also realize the graded air washing of materials to a certain extent, which can not only achieve air washing and impurity removal, but also ensure the relative consistency of the raw materials for fiberboard preparation and ensure the work process.

[0020] In the above process: the established distributor 3 and conveyor plate 4 work together to evenly distribute the raw materials input into the box 2, ensuring their falling speed, preventing material accumulation, and ensuring the smooth progress of the air washing operation. The established air duct 6 receives the airflow from the blower 5 and acts on the falling material through the inside of the box 2, ensuring the air washing process and improving the air washing effect. The established grading plate 13 can, on the one hand, air wash out large batches of raw materials for fiberboard preparation, and on the other hand, separate out fine particles or powder mixed in with the fiberboard raw materials to prevent them from affecting the subsequent processing and preparation of fiberboard, ensuring the quality of the formed workpiece and meeting the usage requirements. This device is reasonably designed, simple in structure, easy to process, and can effectively improve the air washing process of raw materials, ensure the air washing effect, and to a certain extent realize the graded collection of raw materials of different specifications and sizes after air washing, improving the functionality of the device, ensuring the working process, and meeting the usage requirements.

[0021] To ensure the smooth flow of material input, a guide plate 15 is installed inside the box 2 located below one side of the distributor 3. The distributor 3 includes a frame 31 with a herringbone design. Arc grooves 32 are provided on both sides of the frame 31, and a drop chute 33 is provided inside the frame 31. Specifically, the raw material input through the feed inlet 21 is fed into the distributor 3. On the one hand, the raw material is conveyed to both sides through the arc grooves 32, allowing it to fall smoothly. On the other hand, it is conveyed downward through the drop chute 33. This design ensures that the fiberboard raw material is evenly distributed. Under the action of the subsequent conveyor plate 4, the material can be evenly distributed, reducing the possibility of accumulation. This provides a prerequisite for the subsequent air washing process of the material and ensures the use requirements.

[0022] To facilitate the entry of raw materials into the limiting plate 91 and ensure smooth material discharge, a diversion plate 41 is provided on the conveying plate 4. These diversion plates 41 are arranged at an angle from near the geometric center of the conveying plate 4 outwards. Multiple diversion plates 41 are arranged in a mirror image about the geometric center of the conveying plate 4. That is, for diversion plates 41 on the same plane, the extension lines of one end intersect at an acute angle, and the angle gradually decreases from the outside to the inside. This arrangement of the diversion plates 41 ensures that the gaps between adjacent diversion plates 41 on the same side are equidistant, and can guide the falling material to a certain extent, further dispersing it and ensuring even downward flow, thus guaranteeing the smooth operation of the air washing process. To further improve the device... The equipment is designed rationally, with the air pipe 7 tapering from top to bottom. Multiple inclined air distribution plates 71 are installed at the end of the air pipe 7, tapering inwards from the side closest to the diverter plate 10. Specifically, after receiving the gas ejected from the blower 5 at its lower end, the air distribution plates 71 evenly distribute the ejected gas outwards, particularly aligning with the lower part of the conveyor plate 4 to ensure the air washing process. Furthermore, an inclined plate is installed in the gap between the air pipe 7 and the diverter plate 10 to guide unwashed materials such as stones and metals from the raw material to the first discharge hood 11, facilitating the removal of these impurities.

[0023] To further improve the rationality of the equipment setup, the grading plate 13 includes a plate body 131 with an obtuse angle design. The lower end of the plate body 131 is placed inside the collection hood 14, dividing the collection hood 14 into left and right discharge zones. A filter plate 132 is installed in the upper half of the plate body 131. Specifically, the lower half of the grading plate 13 is used to divide the collection hood 14 into front and back zones. One side of the divided collection hood 14 corresponds to the second discharge hood 141, mainly used to collect most of the raw materials for fiberboard preparation. The material is discharged from the second discharge hood 141 towards the external conveying equipment, such as a conveyor belt, to facilitate the external guidance of the material. The other side of the partitioned collection hood 14 corresponds to the third discharge hood 142 and is mainly used to collect fine particles or fiber powder filtered by the filter plate 132 to reduce their impact on the preparation and processing of fiberboard. It can also achieve graded air washing of materials to a certain extent, which can not only achieve air washing and impurity removal, but also ensure the relative consistency of raw materials for fiberboard preparation and guarantee the work process.

[0024] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
