Description

Technical Field

[0001] The utility model relates to the technical field of cooking devices, in particular to a degradable paperboard pulping and cooking device. Background Art

[0002] Pulp cooking is a key step in chemical pulping. It involves treating plant fiber raw materials with specific chemicals under specific temperature, pressure, and time conditions to effectively separate the cellulose fibers. The purpose of cooking is to remove as much lignin as possible from the fiber raw material, retaining the cellulose and hemicellulose, and dissociating the fibers into pulp.

[0003] An existing raw material cooking device for papermaking (Announcement No.: CN221441161U) includes a support column, a crossbeam and a support plate. A cooking tank is installed on the top of the support plate, and the bottom of the crossbeam is connected to a cover via a connecting tube. A lifting member for controlling the raising and lowering of the crossbeam is installed on the support column. A stirring rack is provided in the cooking tank, and a driving member for driving the stirring rack is installed on the cover. A moving wheel is connected to the bottom of the support plate, and plug blocks are connected to both sides of the support plate. A positioning groove that cooperates with the plug block is provided on one side of the bottom of the support column.

[0004] This device has at least the following drawbacks when in use: In the traditional cooking process, steam typically enters the cooking vessel from the bottom or side, which can lead to uneven heating of the raw materials, thus affecting the quality of the slurry. Uneven heating can cause some raw materials to be overcooked while others are undercooked, affecting the consistency and quality of the final slurry. Traditional pulping methods often require large amounts of steam and heat, but due to the uneven heating, a lot of energy is wasted on ineffective heating, resulting in high energy consumption and unfavorable use.

[0033] In this embodiment, a one-way valve (not shown in the figure) may be provided on the nozzle 15 to ensure normal delivery of steam.

[0034] A fixed block 11 is fixedly installed inside the operating room 1. The fixed block 11 is used to support and fix the driving shaft 13, so that the driving shaft 13 can rotate freely while ensuring the conveying effect. A corresponding sealing mechanism should be set at the connection between the two.

[0036] A delivery pipe 10 is fixedly installed at the output end of the steam generator 9, and the other end of the delivery pipe 10 is fixedly connected to the fixed block 11. An exhaust pipe 17 is provided on the driving shaft 13. The delivery pipe 10 is used to transport steam to ensure that the steam can smoothly enter the driving shaft 13, and the exhaust pipe 17 is used to discharge the steam for fixed-point transportation.

[0037] The fixed block 11 and the driving shaft 13 are both hollow structures, and the fixed block 11 is connected to the driving shaft 13 , so that the steam inside the fixed block 11 is smoothly transported to the inside of the driving shaft 13 .

[0038] The paddle body 14 is also a hollow structure, and the exhaust pipe 17 is located inside the corresponding paddle body 14 . The steam inside the driving shaft 13 is discharged into the paddle body 14 through the exhaust pipe 17 and then ejected through the nozzle 15 .

[0039] The bottom of the operating room 1 is a semicircular space, and a temporary storage box 23 is fixedly installed at the bottom of the operating room 1. The temporary storage box 23 is connected to the operating room 1. A discharge pipe 7 is embedded in the temporary storage box 23. A filter plate 24 is embedded in the upper part of the temporary storage box 23. The filter plate 24 is connected to the inner curved surface of the operating room 1.

[0040] The semicircular design facilitates the collection and discharge of materials. The temporary storage box 23 is used to temporarily store the processed slurry. The discharge pipe 7 is used to discharge the filtered slurry. The filter plate 24 is used to filter impurities in the slurry to ensure the output effect.

[0041] A cleaning brush 16 is fixedly installed on the paddle body 14 on the same side. The cleaning brush 16 can directly contact the curved surface of the operating chamber 1 and the filter plate 24.

A fixing frame 21 is fixedly installed inside the operating room 1, and a receiving plate 22 is fixedly installed on the fixing frame 21. The screening plate 18 is used to screen larger particles in the raw materials to ensure the effect of the internal reaction. The qualified granular raw materials fall directly onto the screening plate 18, and the receiving plate 22 supports the other side of the screening plate 18.

[0044] A waste box 8 is movably mounted inside the fixed frame 21. The waste box 8 is located at the end of the lower side of the screening plate 18.

The waste box 8 is located at the end of the lower side of the screening plate 18 to ensure that the waste can fall smoothly into the waste box 8 for subsequent cleaning.

[0049] The driving shaft 13 drives the paddle body 14 to rotate, achieving the effect of stirring and crushing. At the same time, the steam generator 9 sends steam into the driving shaft 13 through the delivery pipe 10, and then sprays it out through the nozzle 15 on the paddle body 14. The rotation of the paddle body 14 can ensure that the raw materials are heated evenly, and the one-way valve on the nozzle 15 ensures the normal delivery of steam.

[0050] A cleaning brush 16 is fixedly installed on the paddle body 14 on the same side.
