Crushed bamboo boiling equipment for preparation of bamboo pulp

Abstract

The invention provides crushed bamboo boiling equipment for preparation of a bamboo pulp. The crushed bamboo boiling equipment comprise a road pavement and a deep pit, wherein the road pavement is used for a forklift to charge and discharge material; the deep pit is arranged at the front end of the road pavement; the road pavement is connected with the deep pit by an arc-shaped ramp; a boiling tank is arranged in the deep pit, and is tightly attached to the bottom surface of the arc-shaped ramp; a heating pipe is arranged in the boiling tank; two winches are arranged on the road pavement; a limiting guide rail is arranged in front of each winch; the cross section of each limiting guide rail is in an U shape; each limiting guide rail extends from the road pavement into the boiling tank; theroad pavement and the arc-shaped ramp are provided with two grooves; a guide rail is arranged in the middle part of each groove, and a boiling pot is arranged on the two guide rails; a cover plate ishinged to a material inlet of the boiling pot; a hydraulic drive rod is arranged at the side wall of the boiling pot, and is used for driving the cover plate to open or close. The crushed bamboo boiling equipment can improve the crushed bamboo boiling efficiency.

Description

technical field [0001] The invention relates to the technical field of papermaking, in particular to broken bamboo stewing equipment used in the preparation of bamboo pulp. Background technique [0002] Bamboo is a perennial lignified plant of Gramineae. my country is the most important bamboo-producing country in the world. Bamboo is widely used, mainly divided into four categories: bamboo shoots, ornamental, traditional materials and industrial materials. Among them, bamboo is the main raw material for papermaking, but in the process of papermaking, it is necessary to cook the broken bamboo chips. The existing cooking equipment uses cooking pots. The bamboo slices are lifted into the boiler, and after cooking, they are grabbed by hanging claws. This is not only inefficient, but also the cooked bamboo slices are relatively loose and difficult to grasp. In addition, due to the large amount of bamboo chips required for papermaking, one-time cooking needs to be in units of to...

Problems solved by technology

Among them, bamboo is the main raw material for papermaking, but in the process of papermaking, it is necessary to cook the broken bamboo chips. The existing cooking equipment uses cooking pots. The bamboo slices are lifted into the boiler, and after cooking, they are grabbed by the hanging claws. This is not only inefficient, but also the bamboo slices after cooking are loose and difficult to grasp

In addition, due to the large amount of bamboo chips required for papermaking, one-time cooking needs to be in units of tons. Therefore, there are requirements for the volume and efficiency of the pot, that is, the existing cooking equipment must have low cooking efficiency and waste of human resources. , feeding and discharging troubles and other problems

For example, the patent name: broken bamboo chip cooking device, patent number: 201410611596.9; although it 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 can not be done. The temperature in the entire cooking cavity is uniform, so there is the same phenomenon as steamed rice, and the steamed broken bamboo chips will turn black if they are not sprayed with lye, which seriously affects the quality of the product and increases the cost for subsequent washing. 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
