Description

Technical Field

[0001] This utility model relates to the field of mechanical pulping equipment technology, specifically to a steam chamber. Background Technology

[0002] In the extrusion impregnation stage of chemimechanical pulping, the processing state of wood chips directly affects the quality and efficiency of pulping. Traditional processes face many challenges in this process. In order to reduce the number of debris and achieve uniform impregnation, good softening and plasticity improvement of wood chips are crucial. Wood chip temperature and moisture content are key factors. However, existing equipment often has difficulty controlling the temperature and moisture distribution of wood chips well, resulting in uneven softening of wood chips, which in turn affects the overall impregnation effect, resulting in a large amount of debris generated during the pulping process and unstable product quality.

[0003] In addition, the presence of some moisture, air, water-soluble colored substances and resins in the chemical composition of wood chips also poses challenges to pulping. These harmful substances react rapidly with the added chemicals, not only wasting the chemicals but also seriously affecting the subsequent bleaching effect, increasing production costs and process complexity. Therefore, pre-steaming of pulping raw materials such as wood chips is an important pulping process before extrusion impregnation, and this process is usually completed in a steaming chamber.

[0004] Chinese Patent Publication No. CN104120614A discloses a rotary feeding steam chamber, which includes a chamber body, a discharge device, and a rotary feeding device. The rotary feeding device includes a feeding disc located at the bottom of the chamber body, the feeding disc including a base plate and feeding blades that can rotate on the base plate. The discharge device includes a housing and a discharge motor. A discharge screw is provided inside the housing, and the screw shaft of the discharge screw is drivenly connected to the discharge motor located on one side of the housing. A discharge port is provided at the lower part of the other side of the housing. The discharge device is located below the feeding disc, and a dropping opening is provided at the part where the base plate of the feeding disc connects with the housing of the discharge device. This invention uses a rotary feeding device to continuously feed raw materials in layers through the dropping opening into the discharge device. Anti-slip strips prevent the material from slipping and rotating, eliminating the bridging phenomenon caused by the volume expansion of the material due to heat, improving the utilization rate of the chamber capacity, and ensuring that the material is sufficiently steam-softened. This effectively improves the effect of subsequent chemical extrusion impregnation and the removal rate of water-soluble colored and resinous substances, while reducing chemical consumption.

[0005] However, the above solution has certain limitations when used, especially when discharging internal materials, it is impossible to discharge them quantitatively. In order to solve the relevant problems, we propose a new type of uniform discharge steam chamber. Utility Model Content

The discharging mechanism 201 can convey materials into the collection box 4 in an appropriate amount or in a quantitative manner through the discharge port 6.

[0027] Example 2: Please refer to Figure 2 As shown, the steam mechanism 301 includes a water storage tank 9, which is filled with water. A heating copper pipe 10 is fixedly connected to the bottom of the inner wall of the water storage tank 9. The heating copper pipe 10 is made of copper, which has good corrosion resistance and high temperature resistance, and is durable. A water inlet is opened on the outer wall of the water storage tank 9. An installation cap is threaded onto the outer wall of the water inlet. Several connecting pipes 8 are fixedly connected to the outer wall of the stirring rod 5. The several connecting pipes 8 are connected to each other through pipes. Several jet nozzles 7 that can release steam are opened on the outer wall of each connecting pipe 8. The several jet nozzles 7 are arranged in an array on the outer wall of each connecting pipe 8. The water storage tank 9 is connected to one of the connecting pipes 8.

[0028] The conveying mechanism 101 includes a material pipe 14, the upper end of which is fixedly connected to the bottom of the material barrel 1. The inner wall of the material pipe 14 is rotatably connected to a spiral auger 13 via a rotating shaft, and the bottom of the material pipe 14 is rotatably connected to a second mating wheel 15. The second mating wheel 15 has several material passages inside, which are circumferentially distributed inside the second mating wheel 15. The upper end of the water storage tank 9 is fixedly installed with a second drive motor 12, and the output end of the second drive motor 12 is fixedly connected to a first mating wheel 11. The first mating wheel 11 and the second mating wheel 15 are tensioned and sleeved together by a belt.

[0029] Please see Figure 3 , Figure 4 and Figure 5 As shown, the feeding mechanism 201 includes a material box 21, which is located below the material tube 14. The upper end of the material box 21 abuts against the bottom of the second mating wheel 15. The material box 21 is fixedly connected to the upper end of the collection box 4 through a connecting arm. A connecting box 22 is fixedly connected to the bottom of the material box 21, and a connecting plate 24 is also fixedly connected to the bottom of the connecting box 22. A rectangular block 18 is also slidably connected to the upper end of the collection box 4.

[0030] Specifically, two linkage slide rods 20 are fixedly connected to the upper end of the collection box 4, and the two linkage slide rods 20 are symmetrically distributed at the front and back of the upper end of the collection box 4. The rectangular block 18 is slidably connected to the outer wall of the two linkage slide rods 20. When the rectangular block 18 slides on the outer wall of the linkage slide rod 20, the linkage slide rod 20 can limit the rectangular block 18 and also has a guiding function, improving the stability of the rectangular block 18 when moving. The outer wall of the linkage slide rod 20 and the inside of the rectangular block 18 are coated with lubricating oil.

[0031] A third drive motor 16 is fixedly installed at the upper end of the collection box 4. A rotating circular plate 17 is fixedly connected to the output end of the third drive motor 16, and a mating rod 19 is fixedly connected to the upper end of the rotating circular plate 17. A rectangular groove is opened on the inner wall of the rectangular block 18, and the outer wall of the mating rod 19 abuts against the inner wall of the rectangular groove. A rectangular tube 23 is fixedly connected to one end of the rectangular block 18 near the connecting box 22, and both the upper and lower ends of the rectangular tube 23 abut against the outer walls of the connecting box 22 and the connecting plate 24.

[0032] Working principle: When in use, after the material barrel 1 is filled with material, the first drive motor 3 is started. The first drive motor 3 will drive the stirring rod 5 to rotate through the reducer 2. The reducer 2 will slow down the stirring rod 5 to prevent the stirring rod 5 from rotating too fast. The stirring rod 5 will stir the material inside the material barrel 1. At this time, the heating copper pipe 10 is started. The heating copper pipe 10 will heat the water inside the water storage tank 9 to boiling. Steam will be discharged from the jet nozzle 7 on the outer wall of the connecting pipe 8. The steam can heat the material inside the material barrel 1. The high temperature wets the material inside, expels the air, and can also perform high-temperature sterilization.

[0033] The second drive motor 12 is started, which drives the first mating wheel 11 to rotate. The first mating wheel 11 drives the second mating wheel 15 to rotate via a belt. The second mating wheel 15 drives the auger 13 to rotate, and the auger 13 conveys the material inside the material bucket 1 into the material round box 21. When the material falls into the material round box 21, the third drive motor 16 is started. The third drive motor 16 drives the rotating disc 17 to rotate, and the rotating disc 17 drives the mating rod 19 to rotate. The mating rod 19 will be inside the rectangular block 18. The rectangular block 18 slides within the inner wall of the rectangular groove. At this time, the rectangular block 18 will slide back and forth on the outer wall of the two linkage sliding rods 20. The rectangular block 18 will drive the rectangular tube 23 to slide between the connecting plate 24 and the connecting box 22. When the rectangular tube 23 slides between the connecting plate 24 and the connecting box 22, when the rectangular tube 23 is separated from the connecting plate 24 and the connecting box 22, the material inside the rectangular tube 23 will fall into the discharge port 6 and then into the collection box 4. (In this embodiment, the amount of material obtained can be known by calculating the number of times the rectangular tube moves back and forth, thereby realizing quantitative conveying.)

[0034] In this invention, if interlocking control between components is involved, the opening / closing / starting / stopping of each component, and the switching / conversion / adjustment of each operating mode can be performed manually or automatically through PLC control logic. The automatic switching / control / adjustment here can be implemented using conventional control logic in existing technology, and will not be elaborated further. In some preferred embodiments, various sensors can be further integrated to achieve automatic switching / conversion / adjustment of relevant operating modes. The material bucket mentioned in this text can also be called a material silo, or simply a storage bin.
