Description

[Detailed Description of the Invention] The present invention relates to a powder and granular material quantitative dispersion device, and more specifically, the present invention relates to a powder and granular material quantitative dispersion device, and more specifically, a spring feeder or a screw feeder that is conveyed by a rotating spring-like spiral body or a vane-like spiral body, etc. The present invention relates to a powder quantitative dispersion device provided at the discharge side tip of a rotating spiral conveyance pipe for conveyance.

For example, a spring feeder is widely used as a convenient powder conveyor. However, since the discharged powder and granules accumulate directly under the discharge port,
Although this method is convenient for supplying powder and granules in a concentrated manner to one location, a separate dispersion means is required to disperse the powder and granules in a desired state.

For this reason, the applicant first connected a horizontal pipe for dispersion to the discharging end of a powder conveyor such as a spring feeder, and installed a sprinkling pipe around the circumferential surface of the horizontal pipe approximately one quarter of the way around the pipe. Quantitative dispersion device for a powder or granular material conveyor, characterized in that a fine structure of an appropriate length is bored in a winding shape, and a groove is located at the bottom at the tip of the tube (Utility Application No. 52-65431) ) was proposed. This prior application has the advantage that it is possible to disperse the powder and granules in a desired range by the distributing action of the spiral narrow grooves. However, in the case of powder or granules having poor fluidity, there is a risk that the powder or granules may cause a bridging phenomenon inside the horizontal dispersion pipe. For this reason, it has been desired to develop a spraying device that can spray even the above-mentioned special powders and granules in a desired state.

This project was devised to meet the above-mentioned demands, and a rotating body that rotates in conjunction with the spiral body of the spring feeder or screw feeder is installed inside the horizontal pipe for dispersion, and the horizontal pipe for dispersion is The object of the present invention is to provide a powder and granular material quantitative dispersion device that can eliminate the bridging phenomenon by stirring the inside and uniformly spread the powder and granular material.

Embodiments of the present invention will be described below based on the drawings.

In FIG. 1, a horizontal dispersion pipe 1 is connected to the discharge side tip of a rotating spiral conveyance pipe 4 consisting of a spring feeder, and a plurality of continuous holes 3 are bored on the circumferential surface of the horizontal pipe. has been done. In FIG. 2, inside the horizontal dispersion pipe 1, there is a helical rotating body 6 having a helical pitch larger than the helical pitch of the spring-like helical body 5 of the rotating helical conveyance pipe 4 consisting of a spring feeder. It is rotatably provided in conjunction with the spiral body 5.

In the above configuration, when the powder conveyed from the hopper by the drive of the spring feeder advances inside the horizontal pipe 1 for dispersion, the powder particles are released from a plurality of consecutive holes 3 of the horizontal pipe 1. In this case, since the spiral rotating body 6 is provided inside the horizontal dispersing pipe 1, the powder is a special powder with poor fluidity. Even in the case where the granular material is agitated by the rotating body 6 and moves forward inside the horizontal dispersing pipe, a certain amount of the granular material is distributed more uniformly from the hole 3 of the horizontal pipe. In this case,
The dispersion state can be arbitrarily controlled by the position and diameter of the hole 3.

Furthermore, although the above is an example of a spring feeder in which the spiral body 5 is a spring-like spiral body, a screw feeder made of a vane-like spiral body formed by providing blades on a spring can also have a similar dispersion effect. It is.

Furthermore, since the rotating body 6 can be formed to have a different helical pitch from that of the spiral body 5, the dispersion state can be controlled to a desired pattern. Further, the shape of the rotating body is not limited to a spring shape, but can be formed into a blade shape, so that it can be controlled even more markedly. Further, when the particle size of the powder or granular material is large, a sufficient stirring effect can be obtained even by using a rotating body made of a rod-shaped body.

Note that the plurality of holes 3 has the advantage that the processability is better than in the case of forming narrow grooves, the dispersion of powder and granules is good, and there is no change over time due to wear.

As explained above, the present invention is capable of dispersing powder and granules with poor fluidity in a desired pattern through the stirring action of the rotating body.
Its practical effects are great.
