Description

Technical Field

[0001] This utility model relates to the field of viscose fiber production technology, and in particular to an impregnation device for viscose fiber production. Background Technology

[0002] Viscose fiber is made from natural wood fiber and cotton linters as raw materials. It is produced by alkalization, aging and sulfonation to make soluble cellulose xanthate, which is then dissolved in alkali solution to make viscose. It is then produced by wet spinning. In the viscose fiber production process, it needs to be impregnated to improve the fiber performance, enhance the bonding force between the fiber and the matrix material, or give the fiber specific functions.

[0003] In traditional impregnation equipment, pulp tends to clump after entering the impregnation tank, making it difficult for the alkali solution to penetrate evenly into the pulp, thus affecting the impregnation effect. In addition, the direct addition of alkali solution often fails to achieve sufficient mixing with the pulp, further reducing impregnation efficiency. Therefore, we propose an impregnation equipment for viscose fiber production to solve the above problems. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing impregnation equipment, such as the tendency of pulp to clump after entering the impregnation tank, making it difficult for alkali solution to penetrate evenly into the pulp, and the inability to achieve sufficient mixing with the pulp when the alkali solution is poured in directly. Therefore, this invention proposes an impregnation device for viscose fiber production.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] An impregnation device for viscose fiber production includes an impregnation tank and a support frame. The impregnation tank extends through the top of the support frame and is fixedly connected to it. Two fixed seats are symmetrically fixed to the outer wall of the impregnation tank, and both fixed seats are bolted to the top of the support frame. A sealing cover is provided on the top of the impregnation tank for sealing. A discharge pipe is fixedly connected to the bottom of the impregnation tank. An inlet pipe is fixedly provided on the top of the sealing cover and is connected to the interior of the impregnation tank. A stirring paddle is rotatably connected to the bottom of the sealing cover inside the impregnation tank. An alkali tank is fixedly provided on the top of the impregnation tank. An inlet hole is provided on the sealing cover below the alkali tank. The bottom of the alkali tank is connected to the inlet hole through an inlet pipe. The device also includes:

[0007] The drive assembly, located on top of the sealed cover, is used to drive the stirring paddle to achieve stirring.

[0008] The beating component is located at the bottom of the sealed cover and is used to beat and disperse the pulp when it enters the impregnation tank, so as to facilitate mixing with the alkali solution and improve the impregnation effect.

[0009] The liquid addition component is located at the bottom of the sealed cap and is used to intermittently add alkali solution, making it easier for the alkali solution to mix with the pulp.

[0010] The heating element is located on the outer wall of the impregnation tank and is used to heat the pulp inside the impregnation tank, thereby improving the impregnation effect.

[0011] In one possible design, the drive assembly includes a gearbox fixedly mounted on top of a sealing cover, the top end of the agitator penetrating the sealing cover and fixedly connected to the output shaft of the gearbox, and a motor fixedly mounted on top of the gearbox, the output end of the motor being fixedly connected to the output shaft of the gearbox.

[0012] In one possible design, the bottom of the impregnation tank is hemispherical, and the outer wall of the agitator fits against the inner wall of the impregnation tank, making it easy to scrape off the pulp adhering to the impregnation tank.

[0013] In one possible design, the striking assembly includes a protective box fixedly disposed at the bottom of a sealing cover, a striking rod rotatably connected to the top inner wall of the protective box, and a driven gear fixedly fitted onto the outer wall of the striking rod inside the protective box.

[0014] In one possible design, the agitator passes through the protective box and is rotatably connected to the protective box. A drive gear is fixedly fitted on the agitator inside the protective box, and the drive gear meshes with the driven gear.

[0015] In one possible design, the heating assembly includes a heating barrel fixedly connected to the outer wall of the impregnation tank, and the interior of the heating barrel is provided with heating wires for heating.

[0016] In one possible design, the liquid addition assembly includes a U-shaped block, which is fixedly installed at the bottom of the sealing cap and directly below the liquid inlet. The inner walls of both sides of the U-shaped block are provided with grooves, and a sliding rod is fixedly installed in each groove. Limiting blocks slide through each of the two sliding rods, and the two limiting blocks are fixedly connected to the same slider. The top of the slider is in contact with the bottom of the sealing cap, and the top of the slider has a through hole. Multiple liquid outlet pipes connected to the through hole are fixedly installed at equal intervals at the bottom of the slider. When the slider slides to one side of the U-shaped block, the through hole on the slider connects with the liquid inlet, thereby introducing the alkali solution from the alkali tank into the impregnation tank.

[0017] In one possible design, a cam is fixedly fitted on the stirring paddle below the drive gear. An opening is provided on the side of the slider near the cam, and a roller is rotatably connected inside the opening. The outer wall of the roller contacts the outer wall of the cam. Springs are fitted on both slide rods, and the two ends of the two springs abut against the inner wall of the corresponding limiting block and the slide groove, respectively. The cam pushes the slider to slide in the two slide grooves of the U-shaped block, and it resets under the elastic force of the two springs, so that the through hole and the liquid inlet are intermittently connected, thereby allowing the alkali solution to be added to the impregnation tank intermittently.

[0018] In one possible design, the discharge pipe extends through the bottom of the heating tank, and an electric valve is fixedly installed on the discharge pipe.

[0019] In this application, pulp and alkali solution are first added to the impregnation tank simultaneously through the feed pipe and the liquid inlet pipe. During the process, the motor is started and the agitator is driven to rotate through the gearbox to stir and mix the pulp and alkali solution. At the same time, since the agitator is fixedly fitted with a drive gear, which meshes with the driven gear fixedly fitted on the beater rod, the rotation of the agitator will drive the beater rod to rotate at the bottom of the protective box, which beats and disperses the pulp that has just entered the impregnation tank. This not only prevents the pulp from forming clumps, but also accelerates the rapid mixing with the alkali solution.

[0020] During the process of adding pulp, the alkali solution in the alkali tank enters the inlet hole through the inlet pipe. When the stirring paddle rotates, the cam on it pushes the roller and the slider to slide in the groove of the U-shaped block, so that the through hole on the slider is connected with the inlet hole, thus adding the alkali solution in the alkali tank into the impregnation tank. When the cam moves away from the roller, the slider is reset under the action of the spring, so that the connected through hole and the inlet hole are disconnected, thus realizing the intermittent addition of alkali solution into the tank.

[0021] The heating element in the heating tank heats the impregnation tank, bringing the pulp to a suitable temperature for impregnation. Once impregnation is complete, the mixture is discharged from the impregnation tank through the discharge pipe by controlling the opening of the electric valve, ready for subsequent fiber production processes.

[0022] In addition, the bottom of the impregnation tank is hemispherical, and the outer wall of the stirring paddle is in contact with the inside of the impregnation tank. This allows the pulp adhering to the inner wall of the impregnation tank to be scraped off during the stirring process, which not only makes the pulp mixed evenly, but also avoids pulp waste and contamination of the inner wall of the impregnation tank.

[0023] Beneficial effects: In this utility model, the impregnation equipment for viscose fiber production, by setting a beating component, can beat and disperse the pulp when it enters the impregnation tank, which not only avoids the pulp from forming clumps, but also accelerates the rapid mixing with the alkali solution and improves the impregnation effect.

[0024] In this utility model, the impregnation equipment for viscose fiber production uses a liquid addition component to intermittently spray alkaline solution onto the pulp in the impregnation tank, making it easier for the alkaline solution and pulp to mix thoroughly and further improving impregnation efficiency.

[0025] In this utility model, the impregnation equipment for viscose fiber production is equipped with a heating component to heat the pulp in the impregnation tank, so that the pulp is impregnated at a suitable temperature, thus ensuring the production quality of the fiber.

[0026] In this invention, by setting up a beating component, the pulp can be beaten and dispersed when it enters the impregnation tank, which not only prevents the pulp from forming clumps, but also accelerates the rapid mixing with the alkali solution. The liquid addition component enables intermittent spraying of alkali solution into the pulp in the impregnation tank, making it easier for the alkali solution to mix fully with the pulp. By setting up a heating component, the pulp in the impregnation tank is heated, so that the pulp is impregnated at a suitable temperature, ensuring the production quality of the fiber.
