Abstract
Disclosed is an air return circulation device for color mixer, comprising a color paste barrel, a quantitative extraction device which consists of a measuring cylinder and a piston mechanism in the measuring cylinder arranged at the side of the paint barrel. A paint outlet which is located at the lower end of the color paste barrel is connected with the lower end of the quantitative extraction device through a valve. The utility model is characterized in that a through hole is arranged between the upper part of the paint barrel and the upper part of the measuring cylinder in the quantitative extraction device. Compared with the prior art, the utility model has the advantage of reasonable design and simple structure, with air in the color paste barrel circulating basically between the color paste barrel and the measuring cylinder, which can prevent effectively the volatility of organic solvents in the color paste to insure tinting precision and extend the service life of the paint.
Description
(1) technical field
The utility model relates to a kind of ventilation device that is used for realizing on the colour mixer gas interior circulation in the mill base bucket, is a kind of circulating return-air device that is applicable on the colour mixer specifically.
(2) background technology
Colour mixer is the paint (particularly emulsion paint) that is used for preparing required color, the color matching equipment of coating.Each colour mixer normally is made up of a plurality of mill base buckets that the different colours mill base is housed.If need quantitatively to extract the colored paint in the bucket, then to finish by quantitative draw-out device, the quantitative draw-out device that is installed in mill base bucket side by with the mill base bucket on valve opening and switch the specific mill base that extracts in a certain color matching paint can that places on the colour mixer.One a selected amount of main lacquer (normally white paint) matches with a certain amount of mill base, obtains the lacquer look and the lacquer amount of required preparation.
The structure of the quantitative draw-out device on the at present used colour mixer paint bucket as shown in Figure 1, mainly comprise graduated cylinder, be installed in piston, the piston rod handle in the graduated cylinder and be located at the outer metering scale of graduated cylinder etc., between paint bucket lower part outlet and graduated cylinder lower end, be connected by a valve.Before each paint color matching, normally repeatedly mention handle on the other hand, pull-up piston rod and piston are drawn in the graduated cylinder mill base in the mill base bucket; And then mill base is squeezed in the mill base bucket, purpose is that the suction mill base does not partly have gas as far as possible in the graduated cylinder in order to make, and gas is discharged from.When taking this mode to extract mill base, because the minimizing of mill base amount in the mill base bucket will produce negative pressure in the mill base bucket, extraneous air can enter in the mill base bucket with the slit that cooperates between the mill base bung by the mill base bucket.Equally, the bucket internal pressure increases again when squeezing into mill base in the mill base bucket again, makes the escaping gas of interior air of bucket and mill base be discharged by the place, slit of mill base bucket and mill base bung again.Repeatable operation is repeatedly constantly discharged along with new air enters with the volatilization gas of the interior mill base of bucket, and the time has been grown the concentration that will make barrel interior mill base to be increased.Can have influence on the color matching precision thus.
(3) summary of the invention
The purpose of this utility model is exactly to provide a kind of barrel interior mill base volatilization gas that reduces to discharge, and can make air between mill base bucket and gauge line carry out the circulating return-air device on the colour mixer of being applicable to of internal communication at existing problem in the above-mentioned prior art.The use of this structure can prolong the storage of mill base in the mill base bucket.
The purpose of this utility model realizes by following scheme: be applicable to that originally the circulating return-air device on the colour mixer comprises the mill base bucket, be installed in mill base bucket side by graduated cylinder and be located at the quantitative draw-out device that the piston mechanism in the graduated cylinder is formed, the lacquer export of mill base bucket lower end links together by the bottom of a valve with quantitative draw-out device, wherein: be provided with consistent reach through hole between the graduated cylinder top in mill base bucket top and quantitative draw-out device.
In the utility model, running through through hole is to be connected with the perforate on mill base bucket top by the airway on the graduated cylinder holder that is located at the graduated cylinder top to constitute, and is added with the graduated cylinder cap below the graduated cylinder holder, can increase the sealing of graduated cylinder.
Mill base bucket upper space and the communication of graduated cylinder upper space run through through hole and also can realize, as set up a transverse tube, or be communicated with a flexible pipe, as long as can be reached the purpose of this utility model by multiple frame mode.
The utility model compared with prior art has the following advantages: reasonable in design, simple in structure, make gas inner loop between mill base bucket and gauge line substantially in the mill base bucket can prevent the volatilization of the organic solvent in the mill base effectively, and guarantee the precision of mixing colours.And prolonged the operating period of mill base.

Fig. 1 is the prior art constructions schematic diagram.
Fig. 2 is a front view of the present utility model.
Fig. 3 is the local amplification view of circulating return-air device.
(5) specific embodiment
The utility model is described further below in conjunction with accompanying drawing:
As Fig. 2, shown in 3: be applicable to that originally the circulating return-air device on the colour mixer comprises mill base bucket (1), be installed in mill base bucket side by graduated cylinder (2) and be located at the quantitative draw-out device that the piston mechanism (3) (comprising piston rod and piston) in the graduated cylinder is formed, the lacquer export (4) of mill base bucket lower end links together by the bottom of a valve (5) with quantitative draw-out device, wherein: be provided with a graduated cylinder cap (6) on the top of graduated cylinder (2), the graduated cylinder holder (8) that has airway (7) is installed on the graduated cylinder cap (6) by screw (10), and the perforate (9) direct and mill base bucket (1) top of the other end of the airway on the holder (7) links together.
When color matching is used, mention handle on the other hand, pull-up piston rod and piston are drawn in the graduated cylinder (2) mill base in the mill base bucket (1); And then mill base is squeezed in the mill base bucket.This action need be carried out repeatedly, and purpose is that the suction mill base does not partly have gas as far as possible in the graduated cylinder in order to make, and gas is discharged from.When in aforesaid operations, extracting mill base, because the minimizing of the mill base amount in the mill base bucket produces negative pressure in the mill base bucket.Meanwhile, the rising of piston, the escaping gas on gauge line inner carrier top is pushed in the mill base bucket of air pressure minimizing by the connection pore on graduated cylinder cap (6), graduated cylinder holder (8) and the mill base bucket.Equally, in the time of in mill base being squeezed into mill base bucket (1), the bucket internal pressure increases, and graduated cylinder (2) top air pressure reduces.Make the interior escaping gas of bucket by mill base bucket top perforate (9), graduated cylinder holder (8), the intercommunicating pore on the graduated cylinder cap (6) is pressed into graduated cylinder (2) top, realizes the inner loop of gas.Though exist between mill base bucket and mill base bung and cooperate the slit.But the gas inner loop between mill base bucket (1) and graduated cylinder (2) in most of mill base bucket has prevented the volatilization of the organic solvent in the mill base effectively.
Subsequently, pull-up piston rod and piston once more, mill base in the mill base bucket is drawn in the graduated cylinder, and extract the mill base of aequum according to the quantitative limit allocation of metering scale (11), move the tap wrench switch valve, gauge line is communicated with the valve body lacquer export, and get colored paint, realize quantitatively joining the purpose of lacquer.
