Abstract

The invention provides a tobacco stem pulp fiber screening device, which mainly includes a screening mechanism, a slurry tank and a driving motor. The screening mechanism includes a bracket, a roller shaft arranged on the bracket, and the roller shaft includes first roller shafts in a triangular distribution, The second roller shaft and the third roller shaft, the crawler-type closed chain plate arranged around the first roller shaft, the second roller shaft and the third roller shaft, a number of fiber strips are evenly arranged on the chain plate, the invention also provides Application of the above equipment in the preparation of white cardboard containing tobacco stem fibers. The tobacco stem pulp fiber screening equipment provided by the present invention can continuously and automatically screen out the long fibers in the tobacco stem pulp fibers, the product quality is uniform and stable, and the efficiency is high, and the length of the selected tobacco stem fibers can be controlled within the range of 1 to 2 cm. It solves the problem in the prior art that the fibers in the tobacco stem pulp are very short and difficult to apply to the papermaking industry.

Description

technical field

[0001] The invention belongs to the technical field of papermaking equipment, and in particular relates to tobacco stem pulp fiber screening equipment and its application. Background technique

[0002] In the tobacco manufacturing industry, a large amount of tobacco stems are produced every year through threshing and redrying. The by-products of this part of the tobacco industry have few comprehensive utilization methods and a low degree of utilization. Therefore, hundreds of thousands of tons of tobacco stem resources are discarded every year, causing environmental pollution. Pollution is also a waste of natural resources.

[0003] In the prior art, the utilization of tobacco stem fibers is mainly limited to the tobacco industry, and the utilization of tobacco stem fibers by the tobacco industry is limited. Fiber is an essential raw material for papermaking industry. If tobacco stem fiber can be used in papermaking, environmental pollution and waste of natu...

Examples

Embodiment 1

[0035] A kind of tobacco stem pulp fiber screening equipment, such as figure 1 shown, including

[0036] Screening mechanism, the screening mechanism includes a bracket 1, a roller shaft arranged on the bracket 1, the roller shaft includes a triangular distribution of the first roller shaft 2, the second roller shaft 3 and the third roller shaft 4, crawler belt Close the chain plate arranged around the first roller shaft 2, the second roller shaft 3 and the third roller shaft 4, and several fiber strips 10 are evenly arranged on the chain plate;

[0037] A slurry pool, the slurry pool is located below the screening mechanism, and the slurry pool includes a raw material pool 5 and a collection pool 6 arranged adjacently;

[0038] A drive motor (not shown in the figure), the drive motor is connected to the roller shaft;

[0039] The height of the bottom of the second roller shaft 3 is smaller than the height of the slurry pool.

[0040] The chain plate includes a first chain ...

Embodiment 2

[0047] A kind of tobacco stem pulp fiber screening equipment, such as figure 2 shown, including

[0048] Screening mechanism, the screening mechanism includes a bracket 1, a roller shaft arranged on the bracket 1, the roller shaft includes a triangular distribution of the first roller shaft 2, the second roller shaft 3 and the third roller shaft 4, crawler belt Close the chain plate arranged around the first roller shaft 2, the second roller shaft 3 and the third roller shaft 4, and several fiber strips 10 are evenly arranged on the chain plate;

[0049] A slurry pool, the slurry pool is located below the screening mechanism, and the slurry pool includes a raw material pool 5 and a collection pool 6 arranged adjacently;

[0050] A drive motor (not shown in the figure), the drive motor is connected to the roller shaft;

[0051] The height of the bottom of the second roller shaft 3 is smaller than the height of the slurry pool.

[0052] The chain plate includes a first chain...

Embodiment 3

[0059] The present embodiment provides the screening method of tobacco stem pulp fiber screening equipment, specifically:

[0060] Such as figure 1 or figure 2 As shown, the fiber 10 is evenly distributed on the chain plate, and the chain plate moves under the drive of the roller shaft. When the fiber 10 moves to the vicinity of the second roller shaft 3 with the chain plate, the fiber 10 enters the slurry in the raw material pool 5 In this moment, the long fiber in the slurry can be attached on the fibrous sliver 10, when the fibrous sliver continues to move with the chain plate, can float out of the liquid surface from the raw material pool 5 slurry subsequently, now can the in the raw material pool 5 The long fiber is pulled out, and the long fiber pulled out is hung on the fiber sliver 10. When the fiber sliver 10 moves to the position of the first chain plate 7, the clear water sprayed from the high-pressure water nozzle 12 is used to wash the fiber sliver 10. The fibe...
