Description

Technical Field

[0001] The invention relates to the technical field of bamboo pulping technology, in particular to bamboo pulping pretreatment equipment. Background Art

[0002] As my country's requirements for wood protection increase, the process of using renewable bamboo resources to make pulp is being increasingly adopted. At present, bamboo replacement cooking process is usually used for pulping. After bamboo is processed into bamboo chips, a series of pretreatment steps are required before cooking: first, the bamboo chips need to be sorted to obtain bamboo chips of appropriate length. If the bamboo chips are too short, the pulping efficiency may be reduced, which will affect the pulp yield. If the bamboo chips are too long, the pulping process may cause excessive fiber fragmentation, which will also affect the quality of the pulp. After the bamboo chips are sorted, they need to be washed to remove impurities and ensure the purity of the pulp. The washed bamboo chips need to be stored for a long time to reduce the moisture in the bamboo chips, so as to reduce the moisture brought into the cooking pot and reduce the amount of alkali needed.

[0003] However, existing technologies for sorting bamboo chips using equipment such as swing screens and linear screens are less effective. Even if the mesh size is adjusted according to the length of the bamboo chips to be sorted, the bamboo chips may fall vertically into the mesh after being vibrated into a vertical position, resulting in inaccurate sorting. Furthermore, washing, storing, and transferring bamboo chips are often done manually, resulting in low efficiency. Summary of the Invention

When the cover plate 35 rotates to cover the upper end of the bamboo frame 33, each hot air blower 36 is located on the upper end surface of the cover plate 35.

[0040] In this embodiment, the first conveying assembly 11, the second conveying assembly 14, the third conveying assembly 15, the fourth conveying assembly 17, and the fifth conveying assembly 18 all use conveyor belt conveyors, the first linear mechanism 12, the second linear mechanism 13, the fifth linear mechanism 212, the sixth linear mechanism 26, and the seventh linear mechanism 24 all use single-axis linear cylinders, and the third linear mechanism 21 and the fourth linear mechanism 211 both use rodless cylinders.

[0041] Working method:

[0042] First, bamboo pieces 4 are placed one by one on the first conveyor assembly 11, with the length direction of the bamboo pieces 4 being roughly parallel to the conveying direction of the first conveyor assembly 11. Then, the bamboo pieces 4 are aligned using the alignment assembly. Specifically, the first fixed push plate 121 is pushed by the first linear mechanism 12 at predetermined time intervals, which further pushes the movable push plate 123. Then, the second fixed push plate 131 is pushed by the second linear mechanism 13, so that the movable push plate 123 and the second fixed push plate 131 can limit the position of the bamboo pieces 4, so that the bamboo pieces 4 are more accurately aligned with the conveying direction of the first conveyor assembly 11.

[0043] Then, when the bamboo chips 4 are conveyed to one end of the first conveying assembly 11 and above the first screening assembly, small pieces of bamboo chips 4 fall into the recovery vehicle 19 below the first screening assembly, while bamboo chips 4 that exceed twice the distance between the main baffle 163 and the auxiliary baffle 162 of the screening assembly will continue to be conveyed to the second conveying assembly 14.

[0044] Similarly, the middle bamboo chips 4, that is, the bamboo chips 4 to be used for pulping, fall into the fourth conveying assembly 17 between the second conveying assembly 14 and the third conveying assembly 15, and the large bamboo chips 4 fall into another recycling vehicle 19 through the third conveying assembly 15.

[0045] Specifically, you can Figures 5 to 7 For example, the second screening component is used to illustrate how to screen bamboo pieces. Figure 5 In the embodiment, the distance between the main baffle 163 and the auxiliary baffle 162 is set to 10 cm, and the length of the bamboo piece 4 is 17 cm. Then, the distance from the center of gravity A of the bamboo piece 4 to its end is about half of 17 cm, that is, 8.5 cm, which is less than 10 cm. Therefore, it will fall into the second screening assembly. For example, Figure 6 、 Figure 7 In the embodiment, the length of the bamboo piece 4 is 25 cm, and the distance from the center of gravity A of the bamboo piece 4 to its end is about half of 25 cm, that is, 12.5 cm, which is greater than 10 cm. Therefore, it will pass horizontally above the second screening assembly and continue to be transported from the second conveying assembly 14 to the third conveying assembly 15.

[0046] The selected middle bamboo pieces are sequentially transported to the net bucket 28 via the fourth and fifth conveyor assemblies 17 and 18 until the net bucket 28 is substantially filled with bamboo pieces 4. The tank cart 261 is then pulled out by the sixth linear mechanism 26. The wash bucket 27 is now filled with clean water to the level of the annular extension 271. The net bucket 28 is then clamped by the gripping assembly. Specifically, the gripping assembly is adjusted in position by the three-axis motion assembly. The seventh linear mechanism 24 then causes the lower horizontal edge of the L-shaped clamp 25 to extend into two of the plurality of clamping holes 282. After gripping, the bamboo pieces 4 are washed. Preferably, the net bucket 28 can be repeatedly raised and lowered into the clean water by the fourth linear mechanism 211 and rotated by the first rotary motor 22. After washing, the net bucket 28 can be lifted above the annular extension 271, but still within the wash bucket 27, for spin drying. The discarded water is then thrown onto the inner wall of the wash bucket 27. Furthermore, after a period of washing, the wash bucket 27 can be moved by a crane for water replacement.

[0047] The washed bamboo chips 4 are transferred via the washing transfer unit 2 to the respective bamboo chip frames 33 in the storage unit 3. Specifically, the second rotary motor 23 swings the net bucket 28 to empty the bamboo chips 4. When the bamboo chip frames 33 are first loaded with bamboo chips 4, some water drips from the drain trough 331 into the water trough 31. This water then flows through the hopper 311 and the water pipe 312 into the water storage bucket 313. If the water storage bucket 313 is full, it can be transferred using a crane. Once each bamboo chip frame 33 is filled with bamboo chips 4, the third rotary motor 34 rotates the cover 35 to cover the bamboo chip frame 33. The hot air blowers 36 are then activated to accelerate the drying of the bamboo chips 4. After a predetermined period of time, the cover 35 is opened.

[0048] Since the third hanging ring portion 333 is provided on the upper portion of the bamboo frame 33 and a discharge port 334 is opened at one end, it is convenient to lift the bamboo frame 33, and then the staff pushes the bamboo chips 4 into the cooking pot.

[0049] The above are only some of the embodiments listed in this application and are not intended to limit this application.
