Description

Technical Field

[0001] This utility model relates to a pulping device, and more particularly to a novel high and low temperature drum pulping material softening device. Background Technology

[0002] Traditional pulping equipment uses a rotating steam inlet at the feed port. This type of steam inlet is an open steam inlet, and the steam reaches the discharge port first under pressure. This causes inconsistent cooking of the material before and after cooking. It often happens that the material is not cooked at the steam inlet. If this happens, it will cause considerable difficulties for subsequent pulping and papermaking.

[0003] In addition, the traditional pulping device uses an internal spiral structure inside the drum. The spiral has a certain height, and the internal spiral continuously pushes the material backward. Under the condition of forced feeding and continuous feeding, the material will accumulate at the feed inlet, resulting in insufficient material loading. When the drum rotates, the internal spiral cannot stir the material, and the material will not turn over, resulting in uneven heating of the cooked material, inconsistent degree of cooking, long cooking time, large steam consumption, and high energy consumption. Utility Model Content

[0004] To address the above problems, this utility model provides a novel high and low temperature drum pulping material softening device, which can stir materials, ensure uniform steam intake inside the drum, achieve even material maturation, provide a large material feed rate, and shorten the cooking time, thereby greatly reducing energy consumption.

[0005] To achieve the above functions, the technical solution adopted by this utility model is as follows:

[0006] A novel high- and low-temperature drum pulping material softening device includes a forced screw feeder, a steam rotary joint, a steam inlet pipe, a quick-opening discharge gate, a roller belt, a large gear, an insulation layer, a steam pipe, a drum, a flapper, a transmission system, a quick-opening feed gate, and a steam hose. The quick-opening feed gate is located at the left end of the drum, and the quick-opening discharge gate is located at the right end of the drum. The roller belt is located at both ends of the outer side of the drum, fixing the drum to the ground. The large gear is located in the middle of the outer side of the drum, and the transmission system is connected to the large gear to enable the drum to rotate. The insulation layer is located inside the drum, and the steam pipe is located inside the insulation layer. The steam rotary joint is located inside the quick-opening discharge gate. The steam inlet pipe is connected to the steam pipe through the steam hose. The steam pipe allows for more controllable and uniform heating of the material. A flapper is also provided inside the drum to stir the material and make it mature evenly. The forced screw feeder is located to the left of the quick-opening feed gate. The forced screw feeder and the steam inlet pipe are respectively set at both ends of the drum, which avoids the steam reaching the discharge port first under pressure, thus preventing the material from being cooked unevenly before and after cooking, and the material being undercooked at the steam inlet.

[0007] Furthermore, a discharge spraying device is also provided at the lower end of the roller. The discharge spraying device includes a spraying conduit, a spraying port, a valve, and a spraying chamber. The spraying port is located at the lower end of the roller. One end of the spraying conduit is connected to the spraying port, and the other end is connected to the spraying chamber. A valve is also provided on the spraying conduit. Traditional discharge methods require waiting for maturation to complete, venting steam first, and then discharging from the discharge port. The discharge spraying device of this invention eliminates the need for steam venting. By opening the valve, the material is discharged into the spraying chamber through the steam pressure via the spraying conduit 16, saving time and making better use of steam energy.

[0008] Furthermore, the flip plate is equipped with a main flip plate, and the main flip plate is equipped with a secondary flip plate. This arrangement is more conducive to the turning of materials and makes the degree of cooking of materials more uniform.

[0009] Furthermore, the steam pipeline includes a steam pipeline fixing bracket, a main steam pipe, a steam distribution pipe, and a steam inlet. The steam distribution pipe is fixed to the inside of the drum by the steam pipeline fixing bracket. The steam inlet is located inside the drum, with one end connected to the steam hose and the other end connected to the steam distribution pipe. The steam distribution pipe also has several vent holes. The vent holes on the steam distribution pipe are small and sparse in the middle, gradually becoming larger and denser towards both ends. This arrangement is to ensure more uniform heating of the material inside the drum and consistent cooking degree.

[0010] The steam inlet pipe is a ring-shaped steam inlet pipe, and the ring-shaped design is also to ensure that the material is heated evenly.

[0011] Advantages of this utility model:

[0012] 1. The unique steam inlet method avoids the situation where steam reaches the outlet first under pressure, which would cause inconsistent cooking of the material before and after cooking, and the material is not cooked at the steam inlet.

[0013] 2. The materials inside the drum can be stirred, resulting in uniform cooking and saving energy;

[0014] 3. The discharge method utilizes steam pressure, resulting in a short discharge time and effective energy utilization. Attached Figure Description

The quick-opening feed gate 2 is located at the left end of the drum 4, the quick-opening discharge gate 8 is located at the right end of the drum 4, the roller belt 3 is located at both ends of the outer side of the drum 4, fixing the drum 4 to the ground, and the large gear 6 is located at the middle part of the outer side of the drum 4. The transmission 13 and the large gear 6... The connection allows the drum 4 to rotate. The insulation layer 7 is located inside the drum 4, and the steam pipe 8 is located inside the insulation layer 7. The steam rotary joint 11 is located inside the quick-opening discharge gate 8. The steam inlet pipe 10 is connected to the steam pipe 5 via the steam hose 9. The steam pipe 5 allows for more controllable and uniform heating of the material. A flap 12 is also provided inside the drum 4 to stir the material, ensuring uniform cooking. The forced screw feeder 1 is located to the left of the quick-opening feed gate 2. The forced screw feeder 1 and the steam inlet pipe 10 are located at opposite ends of the drum, preventing steam from reaching the discharge port first under pressure, thus avoiding inconsistent cooking of the material before and after steaming, where the material is undercooked at the steam inlet.

[0023] like Figure 1At the lower end of the drum 4, a discharge spraying device is also provided. The discharge spraying device includes a spraying conduit 16, a spraying port 14, a valve 15, and a spraying chamber 17. The spraying port 14 is located at the lower end of the drum 4. One end of the spraying conduit 16 is connected to the spraying port 14, and the other end is connected to the spraying chamber 17. A valve 15 is also provided on the spraying conduit 16. Traditional discharge methods require waiting for maturation to complete, venting steam first, and then discharging from the discharge port. The discharge spraying device of this invention eliminates the need for steam venting. By opening the valve 15, the material is discharged into the spraying chamber 17 through the steam pressure via the spraying conduit 16, saving time and making better use of steam energy.

[0024] like Figure 3 The flip plate 12 is equipped with a main flip plate 23, and the main flip plate 23 is equipped with a supporting flip plate 24. This arrangement is more conducive to the turning of materials and makes the degree of cooking of materials uniform.

[0025] like Figure 1 ,like Figure 2 The steam pipe 5 includes a steam pipe fixing bracket 18, a main steam pipe 20, a steam distribution pipe 19, and a steam inlet 21. The steam distribution pipe 19 is fixed to the inside of the drum 4 by the steam pipe fixing bracket 18. The steam inlet 21 is located inside the drum 4, with one end connected to the steam hose 9 and the other end connected to the steam distribution pipe 19. The steam distribution pipe 19 also has several exhaust holes. The exhaust holes on the steam distribution pipe 19 are small and sparse in the middle, gradually becoming larger and denser towards both ends. This arrangement is to ensure more uniform heating and consistent cooking of the material inside the drum.

[0026] like Figure 4 The steam inlet pipe 10 is a ring-shaped steam inlet pipe 22. The ring-shaped design is also for the purpose of uniform heating of the material. Specific implementation examples:

[0028] The forced screw feeder 1 feeds the material through the quick-opening feed gate 2 into the drum 4. The transmission 13 starts working, and the large gear 6 drives the drum 4 to rotate. The material moves backward under the stirring of the flip plate 12. Steam is introduced into the steam hose 9 through the steam inlet pipe 10 to heat the material. The insulation layer 7 reduces heat loss. After the material is cooked, the valve 15 is opened, and the material is discharged from the discharge port 14 through the discharge pipe 16 into the discharge chamber 17 under steam pressure. Clean water is injected into the discharge chamber 17, and the diluted material is output to the next process for papermaking.
