Embodiment

[0032] see Figure 1 to Figure 2 As shown, a line automatic pressure regulating device of the present invention includes: crushing equipment 20, prepreg tank 30, cooking kettle 40, spray pot 50, filtering equipment 60 and yellow liquid storage tank 70;

[0033] The pulverizing equipment 20 is used to pulverize the bamboo raw material; the prepreg tank 30 is used to soak the pulverized bamboo raw material in hot water to generate initial bamboo pulp; the cooking kettle 40 mixes the initial bamboo pulp with a catalyst, Carry out high-temperature and high-pressure cooking to obtain the reaction bamboo pulp, and spray it to the spray pot 50; after the spray pot 50 stirs the reaction bamboo pulp, the reaction bamboo pulp is separated from the solid and liquid by the filter device 60 to obtain yellow liquid and solid residue, the yellow liquid is stored in the yellow liquid storage tank 70 .

[0034] Furthermore, the temperature in the cooking kettle 40 is 160°~200°, especially at ...

Abstract

The invention discloses equipment for preparing bamboo pulp. The equipment comprises pulverization equipment, a preimpregnation tank, a steaming and boiling kettle, a blow tank, filtering equipment and a yellow liquid storage tank; the pulverization equipment is used for pulverizing bamboo raw materials; the preimpregnation tank is used for conducting hot water immersion on the pulverized bamboo raw materials and generating initial bamboo pulp; the steaming and boiling kettle is used for mixing the initial bamboo pulp with a catalyst, conducting high temperature and high pressure steaming and boiling to obtain reaction bamboo pulp and blowing the reaction bamboo pulp into the blow tank; the blow tank is used for stirring the reaction bamboo pulp, then solid-liquid separation is conducted on the reaction bamboo pulp through the filtering equipment, yellow liquid and solid residues are obtained, and the yellow liquid is stored in the yellow liquid storage tank. By means of the equipment for preparing the bamboo pulp, through circulatory pulping conducted through the filtering equipment, the purer bamboo pulp can be obtained.

Description

technical field [0001] The invention relates to a device for preparing bamboo pulp, in particular to an integrated assembly line type device for preparing bamboo pulp. Background technique [0002] Bamboo pulp is a kind of pulp. It is made from moso bamboo, nanzhu, cizhu and other bamboo materials, and is usually prepared by sulfate method and caustic soda method. There are also young bamboos that are degreened and marinated with lime to make semi-clinker. Fiber shape and length, between wood and grass fibers. Easy to apply glue, bamboo pulp is medium fiber length pulp, fine and soft. Pulp has high bulk and tear, but low bursting strength and tensile strength. It has high mechanical strength. But because the bamboo raw material is easy to cause blockage and incomplete reaction in the preparation process, if adopt general-purpose equipment, just easily make yield low. Contents of the invention [0003] The purpose of the invention is to overcome the deficiencies of th...
