Description

Technical Field

[0001] The utility model relates to the technical field of bamboo pulp paper production, in particular to a device for preparing bamboo pulp. Background Technique

[0002] Bamboo pulp is the main component of bamboo pulp paper. During the process of preparing bamboo pulp, cooking equipment is required to cook the small-sized bamboo chips after crushing.

[0003] After retrieval, the patent with the publication number CN212452070U discloses a stirring device for bamboo pulp paper production. By adding a second motor at the bottom of the inner side wall of the cooking tank, the second motor drives the rotating shaft and the stirring rod to rotate, stirring the raw materials inside the cooking pot, so that during cooking, the raw materials can fully contact the heat conduction plate, improving the cooking degree of the raw materials. At the same time, a support frame is added above the fixed frame, and the screw rod is driven to rotate by the rotating disk, driving the lid to move up and down. An annular groove is opened at the bottom of the lid, which is matched with the material pipe and interacts with the sealing ring to increase the sealing performance of the device and improve the cooking efficiency.

[0004] However, in the actual use process of the above solution, due to the relatively small density of the small bamboo chips, during the cooking process, the bamboo chips located in the upper layer will float on the cooking liquid and cannot be completely immersed in the cooking liquid. Although the stirring mechanism can stir the cooking liquid and the bamboo chips, it is still easy to occur that the bamboo chips have different cooking degrees due to uneven heating, which needs to be improved.
