Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to an apparatus for stirring a paint containing a precipitate. The stirring device of the present invention is a device that is installed integrally with a paint pressure pump to perform its functions.

[Prior Art] Generally, when a paint containing a precipitate is pumped using a pressure pump, it is necessary to constantly stir the paint in a container in order to pump the paint uniformly. Therefore,
There is a device in which a stirring blade is placed at the bottom of the container and rotated by an electric or air-driven motor. Also, depending on the speed and speed of precipitation, intermittent rotation is used instead of constant rotation, or instead of a motor, a manual handle is used to occasionally rotate and agitate.

All of these types of stirring using rotating blades are used in various fields to mechanically stir paint.

[Problems that the invention aims to solve] Rotating blades or similar mechanical stirring devices require a driving device for rotation, making them large and complex, and also prohibiting their adoption due to their cost. Difficulties arise. Particularly in the case of flammable paints, electric motors are dangerous in use, so they are limited to air-driven motors.

Furthermore, in the case of a mechanical stirring device, depending on the amount of liquid in the container, the drive motor used for stirring, especially in the case of an air-driven motor, may rotate unstably, resulting in uneven stirring depending on the amount of liquid in the container. There are also problems such as air bubbles being easily mixed into the paint.

In particular, if the amount of paint in the container decreases, the stirring blades will be close to the liquid surface, which will cause air bubbles to get mixed in, scattering from the rotating shaft, etc., making stable stirring impossible, so it cannot be used for stirring small quantities. There's a problem.

The purpose of the present invention is to provide a simple device for stirring the pressure-fed paint that is pumped by a pressure pump, instead of the conventional stirring device as described above. It is possible to obtain a device that prevents instability, air bubbles, etc., and eliminates the need for a driving section and does not cause troubles such as breakdowns.

[Means for Solving the Problems] The present invention provides a paint pump device that uses a paint pump to forcefully feed the paint to a painting gun after stirring the paint stored in a paint container. It communicates with the inside of the paint stored in the paint container, and branches into an outlet part that connects the outlet of the paint pressure pump to a painting gun, and an outlet reflux port that connects to the upper part of the jet pipe stored in the paint container. , the ejection pipe is fixed to the upper opening of the paint container with a removable fitting, and a bent pipe is formed at the lower end of the ejection pipe disposed in the paint container, and the lower end of the bent pipe is formed. A spray nozzle is detachably attached thereto, and an adjustment valve is further provided between the upper part of the spray pipe and the outlet recirculation port of the paint pressure pump.

[Function] Therefore, connect the regulating valve to the outlet reflux port of the paint pressure pump, insert the jet pipe into the container containing the paint to be stirred, position the jet nozzle at the bottom of the paint container, and use the fitting to If it is fixed in place, when the paint pressure pump is operated, the paint whose injection force is adjusted by the adjustment valve is ejected from the outlet recirculation port of the paint pressure pump from the injection nozzle, and the paint is agitated from the bottom. Normally, a part of the paint discharged from the paint pressure pump is used by injecting the recycled paint from the jet nozzle.

[Example] FIG. 1 shows an example of the present invention.
It is used as a set together with a paint pressure pump 1 and a paint container 2 containing paint. Although this paint pressure pump 1 is not particularly limited, for example, a diaphragm type or a plunger type driven by air pressure is often used.

Although the paint container 2 is illustrated as a paint can with an open top, the present invention is not limited to this. Adjustment valve 4 at outlet reflux port 3 of pressure pump 1
is attached, and an ejection pipe 6 is set in the paint container 2 via the flexible pipe 5, if necessary.

Since the spouting pipe 6 needs to be positioned and fixed to the paint container 2, a fitting 8 for fixing both the paint container 2 and the spouting pipe 6 is provided and is detachable.

The injection nozzle 9 is also detachably attached to the tip of a bent pipe 10 provided at the lower end of the injection pipe 6. Therefore, it can be replaced depending on the type of paint or pump, and the injection position and injection angle can also be freely adjusted.

The regulating valve 4 is used to adjust the amount of the recirculated paint to obtain a stirring state suitable for the type and amount of paint, and may be directly connected to the ejection pipe 6.

The fixture 8 is configured such that the vertical position of the jet pipe 6 and the direction of the jet nozzle 9 provided at the lower end can be changed.

[Effect of the invention] As described above, the present invention connects the discharge recirculation port of the paint pressure pump to the jet pipe via the adjustment valve, and injects a portion of the paint discharged from the paint pressure pump from the jet pipe. The paint pump stirs the paint in the paint container.
There is no driving part like conventional electric or air-driven motor type stirrers, and the stirring can be performed without trouble with an extremely simple configuration.

Furthermore, since no stirring blades are required, there is no possibility of air being drawn into the paint or scattering of the paint. For the same reason, even a small amount of paint can be used, and stable stirring as described above can be achieved. Further, in addition to the discharge pressure of the paint pressure pump, the injection force can be adjusted using a regulating valve, and the position of the injection nozzle can also be varied, so that a highly effective stirring state can be obtained.

In this way, according to the present invention, by attaching it to the paint pressure pump, a part of the discharged paint can be used as an agitation flow, which makes it possible to uniformize the paint sucked into the paint pressure pump and to easily pump the paint. It can function as a stirring position for the paint sucked by the pump.
