Description

Technical Field

[0001] This utility model relates to a purification device for processing lignin engineering fiber raw materials. Background Technology

[0002] Lignocellulose mainly comes from natural plants such as wood, which contain a large amount of cellulose and lignin, making them the main raw materials for lignocellulose production. However, after wood is cut into chips, it contains stones and impurities, which need to be removed before it can proceed to subsequent processes. Many small stones adhere to the surface of the wood chips and are difficult to clean by mechanical vibration. Mechanical vibration can also damage the surface of the wood chips, making it easier for small stones to penetrate into the wood chips, which is even more difficult to clean. Therefore, this invention provides a device for removing impurities from lignin-based engineered fiber raw materials. Utility Model Content

[0003] The purpose of this invention is to provide a purification device for processing lignin engineering fiber raw materials, so as to solve the problems mentioned in the background art.

[0004] In order to solve the above-mentioned technical problems, the present invention provides the following technical solution: a lignin engineering fiber raw material processing impurity removal device, including a washing machine and a dehydration tank connected to the discharge pipe of the washing machine; The cleaning machine is equipped with a cleaning impeller; The dehydration chamber includes a primary dehydration chamber and a secondary dehydration chamber that communicates with the primary dehydration chamber. A dehydration filter plate is inclinedly arranged in the primary dehydration chamber. The secondary dehydration chamber is divided into a first drying chamber and a second drying chamber by a dehydration guide filter plate. A dryer is provided on both the first drying chamber and the second drying chamber.

[0005] A guide plate is inclinedly arranged below the dewatering feed filter plate. The downward inclined end of the guide plate passes through the wall of the secondary dewatering chamber and extends to the bottom of the primary dewatering chamber.

[0006] The guide plate has a U-shaped structure with both sides pointing upwards.

[0007] A drive motor is provided on the top of the outer side of the secondary dehydration chamber. The output shaft of the drive motor passes through the chamber and is mechanically connected to the hybrid mechanism, which extends from the first drying chamber to the second drying chamber.

[0008] Compared with the prior art, the beneficial effects achieved by this utility model are: This application includes a washing machine and a dewatering tank connected to the discharge pipe of the washing machine. The washing machine uses a rotating washing impeller to clean the wood blocks and then pushes them into the primary dewatering chamber of the dewatering tank. After the wood blocks are dewatered by the dewatering filter plate, they roll into the first drying chamber of the secondary dewatering chamber, where they are dewatered again by the dewatering guide filter plate and then roll into the second drying chamber before being discharged. This structural design can clean the impurities and stones in the wood blocks without damaging them, thus facilitating the subsequent processing of the wood blocks. Attached Figure Description

[0010] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model. Example

[0011] Please see Figure 1A device for removing impurities from lignin engineering fiber raw materials includes a washing machine 1 and a dewatering tank 2 connected to the discharge pipe of the washing machine 1. The washing machine 1 is equipped with a washing impeller 3, which is driven by an external drive motor. Wood blocks are fed into the washing machine 1 between the blades of the washing impeller 3. Through washing with clean water, impurities such as stones fall to the bottom of the washing machine 1. As the washing impeller 3 rotates, the wood blocks are pushed to the discharge pipe and then enter the dewatering tank 2. The dewatering tank 2 includes a primary dewatering chamber 21 and a secondary dewatering chamber 22 connected to the primary dewatering chamber 21. A dewatering filter plate 4 is inclinedly arranged in the primary dewatering chamber 21. The wood blocks first pass through the primary dewatering chamber. The dewatering filter plate 4 inside chamber 21 allows clean water to fall to the bottom of the chamber, while the wood blocks roll into the secondary dewatering chamber 22. The secondary dewatering chamber 22 is divided into a first drying chamber 51 and a second drying chamber 52 by a dewatering guide filter plate 5. The process of the wood blocks rolling down from the first drying chamber 51 into the second drying chamber 52 achieves secondary dewatering and also extends the rolling distance of the wood blocks, improving the dewatering and drying effect of the wood blocks. Both the first drying chamber 51 and the second drying chamber 52 are equipped with a dryer 6. The start of the dryer 6 can strengthen the drying of the wood blocks during the rolling process, improving the efficiency and effect of the wood block drying. The dried wood blocks are discharged from the bottom of the secondary dewatering chamber 22.

[0012] A guide plate 7 is inclinedly arranged below the dewatering guide filter plate 5. The downward inclined end of the guide plate 7 passes through the wall of the secondary dewatering chamber 22 and extends to the bottom of the primary dewatering chamber 21. During the process of the wood block rolling from the first drying chamber 51 to the second drying chamber 52, the clean water on the wood block is guided by the guide plate 7 through the dewatering guide filter plate 5 to the bottom of the primary dewatering chamber 21.

[0013] The deflector 7 has a U-shaped structure with both sides pointing upwards. Example

[0014] Please see Figure 1 Based on the technical solution of Embodiment 1, a drive motor 8 is provided on the top of the outer side of the secondary dehydration chamber 22. The output shaft of the drive motor 8 passes through its cavity and is mechanically connected to the mixing mechanism 9. The mixing mechanism 9 extends from the first drying chamber 51 to the second drying chamber 52. When the drive motor 8 is started, it drives the mixing mechanism 9 to rotate, so that the air dried in the first drying chamber 51 and the second drying chamber 52 is more evenly distributed. At the same time, the stirring and mixing of the wood blocks allows air to enter between the wood blocks, improving the drying effect.
