Achievement method of chopped bamboo boiling in bamboo pulp preparing process

Abstract

The invention provides an achievement method of chopped bamboo boiling in the bamboo pulp preparing process. The achievement method comprises the steps that S1, a deep pit is formed in the front end of a road surface, and an arc-shaped slope is established between the road surface and the deep pit; S2, a boiling pond is arranged in the deep pit; S3, two winches are arranged on the road surface, and limiting guide rails are arranged in the fronts of the two winches respectively; S4, two tank bodies are formed in the road surface and the arc-shaped slope, a guide rail is arranged in the middle of each tank body, a cooker is arranged on the two guiding rails, and the periphery of the bottom surface of the cooker is provided with a hole; S5, sealing columns are arranged on the periphery of thebottom of the boiling pond; S6, a driver drives a forklift to put chopped bamboos on the road surface into the cooker; S7, water is added into the boiling pond, and meanwhile a cover body of the boiling pond descends through a telescoping air cylinder; S8, the cover body covers the boiling pond through the telescoping air cylinder, water is heated through heating tubes in the boiling pond, and accordingly the chopped bamboos in the cooker are boiled with the water. The chopped bamboo boiling efficiency is improved by adopting the method.

Description

technical field [0001] The invention relates to the technical field of papermaking, in particular to a method for realizing the stewing of broken bamboo in the preparation process of bamboo pulp. Background technique [0002] Bamboo is a perennial lignified plant of the Poaceae family. my country is the most important bamboo-producing country in the world. Bamboo has a wide range of uses. Among them, the main raw material for papermaking is bamboo, but in the process of papermaking, it is necessary to cook the broken bamboo chips. The existing cooking equipments all use cooking pots. Bamboo pieces are snatched into the boiler, and after they are cooked, they are grabbed out through the hanging claws. This is not only inefficient, but also the boiled bamboo pieces are loose and difficult to grasp. In addition, due to the large amount of bamboo chips required for papermaking, the one-time cooking needs to be measured in tons. Therefore, the volume and efficiency of the pot ar...

Problems solved by technology

For example, the patent name: method of steaming broken bamboo, patent number: 201410611620.9; although this method solves the problem of feeding, but in the cooking process, due to uneven spraying of lye (caused by irregular bamboo chips), and the steam pipeline is not The method is to ensure that the temperature in the entire cooking chamber is uniform. Therefore, there is the same phenomenon as steamed rice, and the steamed bamboo chips will turn black if they are not sprayed with lye, which seriously affects the quality of the product. added huge cost

In addition, the existing lye spraying and cooking are mixed together, which will lead to the production of more black liquor, which will put pressure on the subsequent treatment of black liquor, and the cost of black liquor treatment is a difficult problem for the entire industry. If it is not handled well , it will cause environmental damage; and the time to cook a pool with this technology is generally 6-8 hours
