Description

[Detailed description of the invention] This invention relates to a stirring device for wall paint, etc., which is generally called a disper or resolver. The aim is to obtain a uniform product.

Conventionally, a configuration has been known in which stirring is performed using only an impeller fixed to a single rather long blade shaft, which corresponds to the central impeller 16 in FIG. 1, for example.

To explain this tentatively with reference to FIG. 1, by swinging the first case 7 around the cylinder 1 using the handle 10, the paint on the front side of the illustrated vane shaft 16 and on the opposite side thereof can be agitated relatively well. However, there was a problem in that it was not possible to uniformly stir the paint on the side of the cylinder 1 with respect to the blade shaft 16 and the paint on the side E on the opposite side of the cylinder 1, and it took a long time to stir the paint sufficiently.

The present invention aims to solve the above-mentioned problems. Next, embodiments of the present invention will be described with reference to the drawings.

In FIG. 1, which shows a vertical section of the stirring device according to the present invention, a hydraulic cylinder 1 is fixed to the mezzanine floor board or plywood on the ground through a bracket (3.3') having a reinforcing plate 2 in the middle part, and It is standing up in the posture and cylinder 1
The upper end bracket 5 of the elevating shaft 4 fitted therein rotatably supports an elongated first case 7 in a horizontal position via a thrust ball 6.

Vertical stay rod 8 fixed to the upper end of the bracket 5
is fitted into a stay cylinder 9 that is parallel and integral with the cylinder 1, so that when the shaft 4 is raised by hydraulic pressure, the rod 8 is also raised together to prevent the shaft 4 from rotating.

Although the first case 7 is rotatable relative to the lifting shaft 4, a worm, worm wheel, etc. is used to prevent the first case 7 from rotating relative to the cylinder 1 unless the handle 10 provided on the front of the cylinder 1 is turned. is normally locked.

On the first case 7, the motor 1 installed in the case 7
The output shaft 13 of No. 2 is provided with a pulley 14 inside the first case 7, and one end of a V-belt 15 is wrapped around the pulley 14.

The other end of the V-belt 15 is wrapped around a pulley 17 on the vane shaft 16, so when the motor 12 is started, the motor 12
The rotational force is reduced by the V-pulleys 14, 17 and transmitted to the blade shaft 16, and the blade shaft 16 rotates in the direction of arrow A at, for example, 900 rpm.

An impeller 21 is attached to a boss 19 at the lower end of the impeller shaft 16 using a nut 20.

The main body of the impeller 21 is a disc made of a steel plate as shown in FIG. 2, and has a structure in which rectangular blades 23 are inserted and welded into radial grooves 22 provided on the outer periphery of the impeller 21.

Further, the upper end portion of the blade shaft 16 is rotatably supported by the upper and lower wall portions of the first case 7 via bearings 24, respectively.

An elongated earthen wall of a second case 27 is rotatably supported on the lower surface of the tip end (left end in FIG. 1) of the first case 7 via a thrust ball 26, and the second case 27
A bottom wall portion of the blade is supported by the blade shaft 16 via a bearing 28.

The large diameter gear 29 fixed to the upper surface of the second case 27 has
When the pinion 32 fixed to the lower end of the output shaft 31 of the deceleration motor 30 is engaged, and the deceleration motor 30 is started,
The rotational force of the motor 30 is transmitted to the second case 27 via the pinion 32 and the large-diameter gear 29, and the second case 27 rotates in the direction of arrow B at a low speed of, for example, 50 rpm or less.

33 is a bearing.

The lower surface of the second case 27 has sections L1. L2 (L 1 = L 2 in the illustrated example)
Bearings 35 and 36 are installed at positions separated by
The upper end of a long blade shaft 37 is rotatably supported by the bearing 35, and the upper end of a rather short blade shaft 38 is rotatably supported by the bearing 36.

There are three V-belts 41 between the upper half of the pulley 39 and the upper end of the blade shaft 37. A V-belt 43 is stretched between the lower half of the pulley 39 and the pulley 42 at the upper end of the blade shaft 38.

Further, both blade shafts 37, 38 have impellers 44, 45 similar to the impeller 21 at the lower end of the blade shaft 16 at their lower ends, but both impellers 44, 45 have a step L in the upper and lower positions.

Reference numeral 47 denotes a tank for storing all the paint and other materials to be agitated, and has an inner diameter in which the outer circumferential blades 23 of impellers 44 and 45 are adjacent to each other at a small distance L2, and is open at the upper end.

For example, two such tanks 47 are arranged on the same circumference centered on the cylinder 1 when viewed from above.

FIG. 1 shows the state during stirring work, in which a predetermined amount of paint 48 to be toned is placed in a tank 47.

When motors 12 and 30 are started in this state, motor 1
The rotational force of No. 2 is transmitted to the blade shaft 16 through the above-mentioned path, and at the same time, the V-pulley 39 and the V-belt 41.4 in the second case 27
3. ■ It is transmitted to the blade shafts 37 and 38 through the pulleys 40 and 42, and each blade shaft 16 and 37 and 38 rotate in the same direction,
Impellers 21, 44, 45 agitate the entire paint 48.

At the same time, the rotational force of the motor 30 is transmitted to the second case 27 via the pinion 32 and the large-diameter gear 29, and the second case 27 rotates gently in the direction of arrow B about the blade shaft 16.

Therefore, the impellers 44 and 45 revolve around the impeller shaft 16 as shown by the arrow X, and since the impellers 44 and 45 are close to the inner peripheral surface of the tank 47, Stir the entire surface evenly while scraping off any unstirred paint adhering to the surrounding surface.

Since there is a step between the impellers 44 and 45, the paint pushed out laterally by the impeller 44 and the paint pushed out laterally by the impeller 45 are intertwined vertically as shown by arrow C, and further above the paint is pushed out by the impeller 45. 21, the paint extruded from the impeller 45 to the center is agitated by the impeller 21, and the agitation work proceeds efficiently.

After a certain period of time, each impeller is moved upward by a certain amount (intermediate position) using the Synonda 1, stirring is performed there for a certain period of time, each impeller is moved upward (to the upper end position) again, and again after a certain period of time has elapsed. Lower it to the original position shown (lower end position).

Of course, the cylinder 1 can also be raised and lowered continuously.

As a result, all the paint 48 in the tank 47, including the bottom part,
Even the surface side is stirred evenly and evenly.

As explained above, the present invention includes an elevator shaft 4, a tank 47 which is disposed on the side of the elevator shaft 4, has a cylindrical inner wall, and is open upwardly, and a tank 47 which is disposed on the side of the elevator shaft 4 and has a cylindrical inner wall and is open upwardly. a first case 7 rotatably supported around a vertical axis, a second case 27 supported rotatably around a vertical axis at the lower end of the first case 7, and a rotation center and a rotation center of the second case 27. three vertical blade shafts 16, 37, 38 whose upper ends are supported at opposite positions on both sides;
The motors 12, 30 on the case 7, the power transmission mechanisms 29, 32, 41, 43 that transmit the rotational force of the motors 12, 30 to the blade shafts 16, 37, 38 and the second case 27, and each blade shaft 16, 37. .38 Impeller 21 fixedly installed at the lower end
．． 44, 45, and the impellers 44, 45 of the impeller shafts 37, 38 on both sides are arranged close to the inner wall of the tank 47, and the upper and lower impellers 44, 45 are installed at the mounting position of the impeller 44, 45 near the tongue 47. By providing a step in the direction and arranging the central impeller 21 at the top, the impeller can rotate, revolve, and move up and down relative to the material to be stirred in the tank 47, so the following effects can be expected.

(a) Since the impellers 44, 45 of each impeller shaft 37, 38 not only rotate and move up and down, but also revolve, the entire tank can be evenly agitated.

(b) The impeller 44.45 is arranged close to the inner wall of the tank 47 having a cylindrical inner wall, and the impeller 44.45 rotates, revolves, and moves up and down, so that stirring is achieved. At the same time, paint adhering to the inner wall of the tank can be removed, which can greatly contribute to improving product quality, especially when stirring high viscosity substances such as wall paint.

(C) The first case 7 and the second case 2 are
7 together with the impeller shafts 16, 37, 38 and impellers 21, 44.
Since the impeller is raised and lowered by ゜45, the impeller is 21.44
．． Not only can the tank 45 be moved up and down, but also the tank 47 can be moved up and down during work such as replacing the materials to be stirred.
This has the advantage that a large space can be secured near the upper end opening, making work easier.

(d) Since there is a vertical step between the revolving impellers 44 and 45, the paint pushed out laterally by the impeller 44 and the paint pushed out laterally by the impeller 45 are shown by arrow C in FIG. As shown, since the upper and lower sides are intertwined and the impeller 21 is placed further above, the paint pushed out from the impeller 45 to the center is stirred by the impeller 21, and the stirring work proceeds efficiently, so it is uniformly coated in a short time. You can get the best products.
