Abstract

PROBLEM TO BE SOLVED: To provide a stirrer capable of performing stirring by fixed shear and made adaptable even a funnel shaped bottom part by constituting the stirrer of the support members extending from a vertical shaft left and right and a suspension member having a wt. provided to the lower part thereof. SOLUTION: A paint tank 1 has a cylindrical shape of which the bottom part is inclined toward a paint discharge port 2 and the vertical shaft 3 of a stirrer is lowered into the tank at the central part thereof. A stirring member 4 is provided to the lower end of the vertical shaft 3 and constituted of the support members 5 extending from the vertical shaft 3 left and right and movable or flexible suspension members 7 having wts. 6 provided to the lower parts thereof. By this constitution, the wts. 6 receive centrifugal force by the low speed rotation of the vertical shaft 3 and slide along the inclined bottom surface of the paint tank 1 to mix the paint in the tank, especially, a solid material with liquid matter. Therefore, stirring can be performed by low shear in the stirer and this stirrer has adaptability even to the shape of the tank and enables certain and uniform stirring.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention mainly relates to an agitator installed in a paint tank to agitate the paint with a low shear, and particularly to agitate the paint in a funnel-shaped paint tank having an inclined bottom. The present invention relates to a stirrer for low speed stirring.

[0002]

2. Description of the Related Art In this type of stirrer, it is necessary that the paint can be stirred reliably and uniformly even in a coating tank whose bottom is inclined. In particular, when a paste-like material such as a solid material or an aluminum paste is mixed with a liquid material such as a resin paint or a solvent, it is desired to be able to meet the conditions that it is necessary to mix without applying a high share. To this end, a conventional one equipped with a propeller-type stirring blade at the lower end of the vertical shaft cannot be applied well.

Therefore, the present inventor has proposed:
The mechanical structure is simple, it is advantageous in terms of cleaning and maintenance, and the devise of the stirrer has been devised to satisfy the above requirements. That is, the present invention provides a stirrer that can rotate at a low speed and is also adaptable to the shape of a coating tank, particularly the shape of a bottom having a funnel shape or an inclined bottom surface, and that can perform reliable and uniform stirring. Has an aim.

[0004]

Therefore, in the present invention,
In a stirrer equipped with a stirring member at a lower end of a vertical shaft, the stirring member is composed of a support member extending from the vertical shaft to the left and right, and a movable or flexible suspension member having a weight mounted on a lower portion thereof. And

In this case, the suspending member is a plurality of coil-shaped springs whose upper ends are coupled to each other in the longitudinal direction of the supporting member at required intervals, and the weight is a coil-shaped spring commonly attached to the lower ends of these springs. Wire or bar. Further, the suspension member is a plurality of flexible cords whose upper ends are joined at required intervals in the longitudinal direction of the support member, and the weight is a bar commonly attached to the lower ends of these cords. May be.

Further, the suspension member is composed of a large number of flexible cords whose upper ends are joined at a required interval in the longitudinal direction of the support member,
Preferably, it is a piano wire, and the weight may be a large number of weight members individually attached to the lower end of the flexible cord body. Further, the suspension member may be a rod-shaped or strip-shaped member that is slidably supported at a required interval in the longitudinal direction of the support member, is suspended at the upper end thereof, and has a weight at the lower end thereof. Good. The supporting member may itself be a blade member having a stirring function.

Therefore, the stirrer having such a structure can stir with a fixed shear, and is adaptable to the shape of the coating tank, in particular, the shape of the funnel or the bottom having an inclined bottom surface, and ensures reliable and uniform stirring. Is possible.

[0008]

BEST MODE FOR CARRYING OUT THE INVENTION Embodiments of the structure of the stirrer of the present invention will be specifically described below. Here, the bottom of the paint tank 1 has a cylindrical shape inclined toward the paint discharge port 2 side, and the vertical shaft 3 of the stirrer is lowered into the tank at the center thereof. The stirrer is equipped with a stirrer 4 at the lower end of the vertical shaft 3, as shown in FIGS. 1 and 2, for example.
The stirring member 4 is a support member 5 extending from the vertical shaft 3 to the left and right.
And a movable or flexible suspension member 7 having a weight 6 attached to the lower part. In this case, the suspension member 7 is a large number of flexible cords, preferably piano wires, whose upper ends are joined at required intervals in the longitudinal direction of the support member 5, and the weights 6 are individually flexible cords. Is a number of weight members attached to the lower end of the.

In such a construction, the weight 6 is subjected to centrifugal force by the low speed rotation of the vertical shaft 3 driven by a motor (not shown) so that the weight 6 slides on the inclined bottom surface of the paint tank 1 so that the inside of the tank is The above-mentioned paint, in particular, a paste-like material such as a solid material and an aluminum paste is mixed with a liquid material such as a resin paint and a solvent. Therefore, with the stirrer having such a configuration, it is possible to stir with a low shear rate, and moreover, it is adaptable to the shape of the coating tank, especially the shape of the funnel or the bottom having an inclined bottom surface, and reliable and uniform stirring is possible. is there.

As shown in FIGS. 3 and 4, the suspension member 7 is a plurality of coil-shaped springs whose upper ends are joined at a required interval in the longitudinal direction of the support member 5, and the weight 6 is composed of these springs. It may be a coiled wire or a bar commonly attached to the lower end. Further, the suspension member 7 is
As shown in FIG. 5, it is a plurality of flexible cords whose upper ends are joined at required intervals in the longitudinal direction of the support member 5, and the weight 6 is a bar commonly attached to the lower ends of these cords. May be.

Further, as shown in FIGS. 6 and 7, the suspension member 7 is vertically slidably supported by a slit guide 5a formed at required intervals in the longitudinal direction of the support member 5 and suspended at its upper end. It may be a rod-shaped or strip-shaped member that is held and has the weight 6 integrally provided at its lower end. In addition, in all the above-described embodiments, the supporting member 5 may be a blade member having a stirring function itself as shown in FIG.

[0012]

As described above in detail, the present invention provides a stirrer having a lower end of a vertical shaft equipped with a stirrer, wherein the stirrer has a support member extending from the vertical shaft to the left and right and a weight attached to the lower part. Since it is composed of a movable or flexible suspension member, it can be stirred with a low shear, and it is also adaptable to the shape of the coating tank, especially the shape of the funnel or the bottom with an inclined bottom surface. The excellent effect that uniform stirring is possible can be exhibited.
