Abstract

PROBLEM TO BE SOLVED: To efficiently disperse fibers at a high speed and add the dispersed fibers to an asphalt when mixing the fibers in a vegetable fiber-mixed asphalt. SOLUTION: This system has a structure for making vegetable fibers collide with barrier valves 3 in a pipe 1 under a wind pressure of high-pressure air by a fan 2 and dispersing the vegetable fibers. The barrier valves 3 are continuously attached to the upper and lower sides in the pipe 1. The vegetable fibers repeating the collision are then gradually dispersed. Furthermore, the high- pressure air plays a role in delivery to an asphalt plant and addition to the asphalt and bears a series of operations.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to a method for dispersing asphalt mixed with vegetable fibers in a fiber dispersion apparatus for adding vegetable fibers.

[0002]

2. Description of the Related Art As a conventional addition method, fibers are dispersed by hand by tearing the fibers by hand, and the fibers are poured into asphalt.

[0003]

The conventional addition method has problems in that it is not dispersed sufficiently, cannot be added evenly to asphalt, and is inefficient because it is manual. In addition, since the fibers are fine, they rise into the air and the working environment is poor. Not only that, it is not good for the surrounding environment.

[0004] The present invention utilizes the pressure of air sent out by a motor fan, sprays plant fibers together with high-pressure air on multiple overlapping barrier valves, and strikes the fibers against the barrier valve. Further, since the fibers are lightweight (specific gravity: 0.1), they are intended to be evenly dispersed during delivery by high-pressure air.

[0005]

SUMMARY OF THE INVENTION The fiber dispersing apparatus according to the present invention has a gist that a structure for dispersing vegetable fibers must be appropriately dispersed and added to kneaded asphalt. It is.

The above-mentioned fiber dispersing apparatus has a structure in which high-pressure air is used to blow the fibers to collide them with the wall surface, and the fibers are dispersed by the impact. A valve is installed to apply a large amount of impact to disperse plant fibers.

The method used for dispersing the fibers is a method which is useful for the movement and addition of the fibers, so that the entire series of operations can be covered with high-pressure air.

[0008]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A preferred embodiment of the fiber dispersion device according to the present invention will be described below with reference to FIG. The fiber dispersing apparatus mainly comprises a steel pipe 1, and has an inlet 4 for introducing fibers, a motor 5 as a power source of a fan, and a delivery pipe 7 for sending dispersed fibers to an asphalt plant.

In this embodiment, vegetable fiber is put into the inlet 4 and an appropriate amount is sent to the tube 1 by the measuring device 6.

The fan 2 is rotated by the motor 5 to generate high-pressure air, and the pressure causes the fibers to collide with the barrier valve 3.

The colliding fibers are blown up or down by pressure and collide with the next barrier valve. By repeating this, the fibers are gradually dispersed and delivered to the asphalt plant through the delivery pipe 7.

[0012]

Since the present invention is configured as described above, it has the following effects.

[0013] With the mechanization of the fiber dispersion function, a uniform additive can be obtained without dispersion unevenness.

According to the fiber dispersion structure, asphalt 1
Necessary amount of addition 9.0 per 3000 kg of mixing time
kg fiber is very efficient because dispersion and delivery are completed within 5 seconds.

The effects obtained by the practice of the present invention are extremely large since the measurement, dispersion, delivery, and addition of the plant fiber can all be carried out in a closed apparatus, so that there is no effect on the environment or the human body.

[0016] Since the measurement is performed by the scale, an appropriate amount of fiber can be added to the asphalt, and the quality is improved.

The main power source is only a motor, and since there is no movable part in the pipe 1 having a dispersing function, it is simple and easy to manufacture.
