Description

CROSS-REFERENCE TO RELATED APPLICATIONS

This is a U.S. patent application which claims the priority and benefit of Chinese Patent Application Number 202211584829.1, filed on Dec. 10, 2022, the disclosure of which is incorporated herein by reference in its entirety.

TECHNICAL FIELD

The present invention relates to the technical field of bamboo fiber production, and in particular to a bamboo fiber production device.

BACKGROUND

Because bamboo charcoal fiber has very strong adsorption capacity, it can absorb harmful substances such as formaldehyde and is widely used in the field of air filtration. Bamboo is fired into bamboo charcoal at a high temperature and then prepared into a fiber material. In order to speed up the firing of bamboo, the bamboo is dried by a dryer before firing.

According to search, Chinese Patent Application No. CN112524911A discloses a bamboo charcoal fiber production device with a high drying efficiency, including a base, a sliding block, a roller and a sliding rail, wherein the sliding block is installed on a top of the base, the sliding rail is arranged outside the roller, the roller movably fits with the sliding block through the sliding rail, and a drying chamber, a bearing and a pushing mechanism are arranged on the roller; because of a small frictional force between bamboo and an inner wall of the roller, the bamboo is in a static state at a bottom of the roller for a long time; a support block of the pushing mechanism is moved and returned to push the bamboo to rotate, which is conducive to continuous contact between the bamboo surface and the inner wall of the roller, to accelerating a drying speed of the bamboo, and to uniform heating of the bamboo; because water drops are evaporated to the bamboo surface after the bamboo is heated, the water drops and impurities left on the bamboo surface slow down the evaporation of water, and the water drops and impurities on the outer wall of the bamboo are removed by a scraper of a blade, which is conducive to accelerating the evaporation of water inside the bamboo and the drying speed of the bamboo.

The above-mentioned technical solution has the following deficiencies:

In the above-mentioned technical solution, in order to ensure the drying effect of bamboo, it is necessary to rotate the roller. However, because the drying chamber is arranged inside the roller, a heating module inside the drying chamber rotates synchronously with the roller, which causes the problem that a line of the heating module will be wound, thereby affecting normal use of the whole device; moreover, after the bamboo is dried, it is difficult to take out the dried bamboo timely due to high temperature inside the roller.
