Description

Technical Field

[0001] This utility model belongs to the field of wood fiber processing technology, and in particular relates to a wood fiber spiral extrusion dewatering device. Background Technology

[0002] Wood fiber is a natural organic material. Screw extrusion dewatering can effectively remove moisture from wood fibers. However, if the wood fiber material contains excessively long fibers or impurities and lumps, it can easily cause blockages at the feed inlet. To minimize feed inlet blockage and ensure smooth material entry into the dewatering device, thereby preventing disruption to the continuity and efficiency of the entire production process, a wood fiber screw extrusion dewatering device was designed. This device involves feeding material into the inner cavity of a storage cylinder, while a support rod and cam drive the perforated plate to frequently vibrate, loosening and dispersing the material within the storage cylinder. This effectively prevents feed inlet blockage, allowing the material to smoothly enter the dewatering device and thus maintaining the continuity and efficiency of the entire production process. Utility Model Content

[0003] The purpose of this invention is to provide a wood fiber spiral extrusion dewatering device that minimizes the risk of feed inlet blockage, allowing materials to enter the dewatering device smoothly and thus avoiding disruption to the continuity and efficiency of the entire production process, thereby solving the aforementioned technical problems.

[0005] Preferably, a spring is welded between the bottom of the support plate and the top of the bending plate, and the surface of the telescopic rod is slidably connected to the inner cavity of the spring.

[0006] Preferably, straight rods are fixedly connected to both the left and right sides of the inner cavity of the screw extrusion dewatering machine, and the bottom of the two back-to-back side of the two slot plates are rotatably connected to the surfaces of the two straight rods respectively.

[0007] Preferably, both ends of the straight rod extend through the surface of the storage cylinder and are fixedly connected to a limiting round head, and the top of the screw extrusion dewatering machine is fixedly connected to a motor by bolts.

[0009] Preferably, a belt is connected between the roller and the second roller, and guide plates are fixedly connected to both sides of the inner cavity of the storage cylinder, with both guide plates close to the top of the inner cavity of the storage cylinder.

[0010] The beneficial effects of this utility model are:

[0011] 1. This utility model uses a starting motor to drive the support rod and cam to rotate, which in turn pushes the bending plate and the perforated plate back and forth, thereby shaking and loosening the input material. This can minimize the possibility of the feed inlet being blocked, so that the material can smoothly enter the dewatering device, thereby avoiding affecting the continuity of the entire production process and the production efficiency.

[0012] 2. By setting a limiting round head, this utility model can limit the position of the straight rod, which can prevent the straight rod from sliding during the shaking of the perforated plate;

[0023] In the following description, embodiments of the wood fiber spiral extrusion dewatering device of the present invention will be described with reference to the accompanying drawings. Example 1

[0024] Figure 1-6 This invention illustrates an embodiment of a wood fiber spiral extrusion dewatering device, comprising: a storage cylinder 2 connected to the feed inlet of a spiral extrusion dewatering machine 1; support rods 3 rotatably connected to the upper and lower sides of the inner cavity of the storage cylinder 2; two cams 4 fixedly connected to the surfaces of the two support rods 3; support plates 5 fixedly connected to the upper and lower sides of the inner cavity of the spiral extrusion dewatering machine 1; three telescopic rods 6 fixedly connected to the bottom of the two support plates 5; and bending plates 7 fixedly connected to the bottom ends of the three telescopic rods 6; the surfaces of the cams 4 slidably connected to the bottom of the bending plates 7; and two bending plates 7 having opposite sides... A perforated plate 8 is fixedly connected. A spring 9 is welded between the bottom of the support plate 5 and the top of the bending plate 7. The surface of the telescopic rod 6 is slidably connected to the inner cavity of the spring 9. Straight rods 10 are fixedly connected to both the left and right sides of the inner cavity of the screw extrusion dewatering machine 1. The bottom of the opposite side of the two perforated plates 8 is rotatably connected to the surface of the two straight rods 10 respectively. The front and rear ends of the straight rods 10 penetrate to the surface of the storage cylinder 2 and are fixedly connected to the limiting round head 11. By setting the limiting round head 11, the position of the straight rod 10 can be limited, which can prevent the straight rod 10 from sliding during the shaking of the perforated plate 8. Example 2

[0025] Figure 1-6This invention illustrates an embodiment of a wood fiber spiral extrusion dewatering device, comprising: a storage cylinder 2 connected to the feed inlet of a spiral extrusion dewatering machine 1; support rods 3 rotatably connected to the upper and lower sides of the inner cavity of the storage cylinder 2; two cams 4 fixedly connected to the surfaces of the two support rods 3; support plates 5 fixedly connected to the upper and lower sides of the inner cavity of the spiral extrusion dewatering machine 1; three telescopic rods 6 fixedly connected to the bottom of the two support plates 5; a bending plate 7 fixedly connected to the bottom of the three telescopic rods 6; the surfaces of the cams 4 slidably connected to the bottom of the bending plate 7; and a leak-proof device fixedly connected to the opposite sides of the two bending plates 7. The top of the screw extrusion dewatering machine 1 is bolted to a motor 12. The output shaft of the motor 12 is fixedly connected to a roller 13 via a flange. The front ends of the two support rods 3 extend to the front side of the storage cylinder 2 and are fixedly connected to rollers 14. A belt drives the rollers 13 and 14. Guide plates 15 are fixedly connected to the left and right sides of the inner cavity of the storage cylinder 2. The two guide plates 15 are close to the top of the inner cavity of the storage cylinder 2. By setting the guide plates 15, the material fed into the inner cavity of the storage cylinder 2 can be guided, so that the material can fall into the inner cavity of the storage cylinder 2 more concentratedly.

[0026] Working principle: When using this utility model, the user puts the material into the inner cavity of the storage cylinder 2, and at the same time starts the motor 12 to drive the roller 13 to rotate. Then, the roller 14 drives the two support rods 3 to rotate. When the support rods 3 rotate, they drive the cam 4 to rotate and reciprocate to push the bottom of the bending plate 7. At this time, under the support and limit of the straight rod 10, the sieve plate 8 is driven to reciprocate to shake, and the put-in material is shaken and loosened. This can avoid the inlet from being blocked as much as possible, so that the material can enter the dewatering device smoothly, thereby avoiding affecting the continuity of the entire production process and production efficiency.

[0027] In summary, this wood fiber spiral extrusion dewatering device, by starting the motor 12 to drive the support rod 3 and cam 4 to rotate, and then reciprocatingly pushing the bending plate 7 and the perforated plate 8, thereby shaking and loosening the input material, can minimize the occurrence of feed port blockage, so that the material can smoothly enter the dewatering device, thereby avoiding the impact on the continuity of the entire production process and production efficiency.
