Description

Technical Field

[0001] This application relates to the field of cellulose production equipment technology, and in particular to an automated continuous cellulose washing buffer tank. Background Technology

[0002] Cellulose, as an important natural polymer material, is widely used in textiles, papermaking, food, medicine and other fields. Washing is one of the key processes in cellulose production, used to remove impurities and residual chemicals.

[0003] Traditional cellulose washing processes mainly employ intermittent operation, where cellulose is manually or using simple mechanical devices to place it into washing tanks in batches for washing. Although this process is relatively simple, it has obvious drawbacks such as low production efficiency, high labor intensity for workers, and uneven washing results. Therefore, an improvement has been made to an automated continuous cellulose washing buffer tank. Utility Model Content

[0004] In view of the shortcomings of the prior art, this application provides an automated continuous cellulose washing buffer tank, which overcomes the shortcomings of the prior art and aims to solve the problems in the prior art.

[0005] To achieve the above objectives, this application provides the following technical solution: an automated continuous cellulose washing buffer tank, comprising a washing tank, a feed pipe fixedly connected to the top of the washing tank and a conveying pipe fixedly connected through the feed pipe, a discharge pipe fixedly connected to the bottom of the washing tank, a solenoid valve fixedly installed on the discharge pipe, a discharge unit fixedly connected to the lower end of the discharge pipe, a stirring rod arranged inside the washing tank, a plurality of stirring blades fixedly connected to the outer wall of the stirring rod, fixed rods symmetrically arranged on both sides of the stirring rod inside the washing tank, a plurality of guide plates fixedly connected to the outer wall of the fixed rods near the stirring rod, and a drive unit for driving the stirring rod to rotate fixedly installed at the center of the upper surface of the washing tank, the drive unit consisting of a drive motor and a reducer, the output end of the drive motor being fixedly connected to the upper end of the stirring rod through the reducer.

[0006] By adopting the above technical solution, materials are fed into the washing tank through the conveying pipe and the feed pipe. The drive motor drives the stirring rod to rotate through the reducer. The rotation of the stirring rod drives the stirring blades to rotate, stirring the mixture of cellulose and washing liquid. The rotating stirring rod and the stationary fixed rods on both sides cooperate to form a special stirring mode. The rotation of the stirring rod drives the material to mix inside the washing tank, while the stationary fixed rods and guide plates play the role of guiding and dispersing the material, which helps to improve the stirring efficiency and uniformity, and can improve the cellulose washing efficiency. After washing, the cellulose is transported to the discharge unit through the discharge pipe and then discharged by the discharge unit.

[0007] As a preferred technical solution of this application, the discharge unit includes a discharge bin disposed below the washing tank, an inlet fixedly connected to the discharge pipe at the top of the discharge bin, a spiral feeding shaft rotatably connected inside the discharge bin, a conveying motor for driving the spiral feeding shaft to rotate fixedly installed on the side wall of the discharge bin, and a discharge port disposed on the bottom of the discharge bin away from the inlet.

[0008] By adopting the above technical solution, the washed cellulose is conveyed to the discharge hopper through the discharge pipe and the inlet. The conveyor motor drives the screw feed shaft to rotate, thereby moving the cellulose in the discharge hopper toward the discharge outlet, so that the cellulose is discharged from the discharge outlet.

[0009] As a preferred technical solution of this application, the upper end of the fixing rod is fixedly connected to a connecting seat, and the connecting seat is fixedly installed on the top wall of the washing tank by fixing screws.

[0010] By adopting the above technical solution, the fixing rod is fixedly installed inside the washing tank by means of the connecting seat and fixing screw.

[0011] As a preferred technical solution of this application, a gap is left between the stirring blade and the fixed rod, and the stirring blade and the guide plate are staggered inside the washing tank.

[0012] By adopting the above technical solution, collisions between the stirring blades and the fixed rod and guide plate are avoided, ensuring the safe operation of the equipment under high-speed stirring.

[0013] As a preferred technical solution of this application, a connecting block is fixedly connected to the lower end of the stirring rod, and vertical rods are symmetrically connected to the upper surface of the connecting block. A scraper is fixedly sleeved on the outer wall of the vertical rod, and the side wall of the scraper is in contact with the inner wall of the washing tank.

[0014] By adopting the above technical solution, the scraper is rigidly connected to the stirring rod through the vertical rod. When it rotates synchronously with the stirring rod, its edge is closely attached to the inner wall of the washing tank, continuously scraping off the adhering cellulose residue and returning it to the mixing zone.

[0015] As a preferred technical solution of this application, the stirring rod, stirring blade, fixing rod, guide plate, connecting block, vertical rod and scraper are all stainless steel components.

[0016] By adopting the above technical solutions, the components made of stainless steel are not easily corroded and have a long service life.

[0017] As a preferred technical solution of this application, a control panel is fixedly installed on the outer wall of the washing tank, and the control panel is electrically connected to the drive motor, solenoid valve and conveyor motor through wires.

[0018] By adopting the above technical solution, the stirring parameters can be set through the control panel, and the running status of the drive motor can be directly adjusted to achieve precise control of the cellulose washing intensity. The control panel controls the solenoid valve to open the discharge pipe for material feeding, and links the start and stop of the conveyor motor to ensure that the discharge unit operates synchronously with the washing end signal, avoiding material accumulation or idling.

[0019] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0020] In this invention, materials are fed into the washing tank through a conveying pipe and a feed pipe. A drive motor drives a stirring rod to rotate via a reducer. The rotation of the stirring rod drives the stirring blades to rotate, thus stirring the mixture of cellulose and washing liquid. The rotating stirring rod and the stationary fixed rods on both sides work together to form a special stirring mode. The rotation of the stirring rod causes the materials to mix inside the washing tank, while the stationary fixed rods and guide plates guide and disperse the materials, which helps to improve stirring efficiency and uniformity, and improves the washing efficiency of cellulose. After washing, the cellulose is transported to the discharge unit through the discharge pipe and then discharged by the discharge unit.

A drive unit is provided to drive the stirring rod 7 to rotate. The drive unit consists of a drive motor 9 and a reducer 10. The output end of the drive motor 9 is fixedly connected to the upper end of the stirring rod 7 through the reducer 10. In use, the material is fed into the washing tank 1 through the feed pipe 3 and the feed pipe 2. The drive motor 9 drives the stirring rod 7 to rotate through the reducer 10, and the rotation of the stirring rod 7 drives the stirring blades 8 to rotate to stir the mixture of cellulose and washing liquid. The rotating stirring rod 7 and the fixed rods 11 on both sides cooperate to form a special stirring mode, which can improve the cellulose washing efficiency. After washing, the cellulose is transported to the discharge unit 6 through the discharge pipe 4 and discharged by the discharge unit 6.

[0030] In this embodiment, as Figure 1 and 4As shown, the discharge unit 6 includes a discharge bin 61 located below the washing tank 1. The top of the discharge bin 61 is provided with an inlet 64 fixedly connected to the discharge pipe 4. A screw feed shaft 62 is rotatably connected inside the discharge bin 61. A conveying motor 63 that drives the screw feed shaft 62 to rotate is fixedly installed on the side wall of the discharge bin 61. A discharge port 65 is provided on the bottom of the discharge bin 61 away from the inlet 64. In use, the washed cellulose is conveyed into the discharge bin 61 through the discharge pipe 4 and the inlet 64. The screw feed shaft 62 is driven to rotate by the conveying motor 63, thereby moving the cellulose in the discharge bin 61 toward the discharge port 65, so that the cellulose is discharged from the discharge port 65.

[0031] In this embodiment, as Figure 2 and 3 As shown, a connecting seat 13 is fixedly connected to the upper end of the fixing rod 11. The connecting seat 13 is fixedly installed on the top wall of the washing tank 1 by fixing screws 14. In use, the fixing rod 11 is fixedly installed inside the washing tank 1 by the connecting seat 13 and fixing screws 14.

[0032] In this embodiment, as Figure 2 and 3 As shown, there is a gap between the stirring blade 8 and the fixed rod 11.

The control panel 18 is electrically connected to the drive motor 9, the solenoid valve 5, and the conveyor motor 63 via wires. During use, the stirring parameters are set through the control panel 18, and the running status of the drive motor 9 is directly adjusted to achieve precise control of the cellulose washing intensity. The control panel 18 controls the solenoid valve 5 to open the discharge pipe 4 to perform the material feeding operation, and links the start and stop of the conveyor motor 63 to ensure that the discharge unit 6 operates synchronously with the washing end signal, avoiding material accumulation or idling.

[0036] The working principle of this utility model is as follows: When using the automated continuous cellulose washing buffer tank of this application, the material is fed into the washing tank 1 through the conveying pipe 3 and the feed pipe 2. The stirring parameters are set through the control panel 18 to adjust the running status of the drive motor 9. The drive motor 9 drives the stirring rod 7 to rotate through the reducer 10. The rotation of the stirring rod 7 drives the stirring blade 8 to rotate to stir the mixture of cellulose and washing liquid. The rotating stirring rod 7 and the fixed rods 11 on both sides cooperate to form a special stirring mode, which can improve the cellulose washing efficiency. After the washing work is completed, the control panel 18 controls the solenoid valve 5 to open the discharge pipe 4.
