Description

Technical Field

[0001] The utility model belongs to the technical field of coating production, in particular to an alkyd paint solvent adding device which does not contain heavy metals. Background Art

[0002] Alkyd paint, also known as alkyd resin paint or alkyd resin coating, is mainly composed of alkyd resin and is currently the largest type of coating produced in China. Traditional alkyd resin coating is solvent-based and contains a large amount of solvent (mass ratio greater than 40%). The main ingredients are: alkyd resin, No. 200 solvent gasoline, drying agent (containing cobalt, manganese, lead, zinc, calcium, or cobalt, manganese and rare earth), and anti-skinning agent. When preparing alkyd paint, it is necessary to add various solvents, most of which are in liquid form. However, there are the following disadvantages when adding solvents:

[0003] 1. In the preparation process of alkyd paint, the most important thing is the ratio of various solvents, that is, the amount of addition. Once a large error occurs, it is easy to cause the finished product to be unqualified. This requires ensuring the accuracy of the amount of input when adding feed, but as far as the current feeding method is concerned, it still needs to be improved;

[0004] 2. Secondly, since alkyd paint is used as a spray coating, it needs to have a certain fineness and cannot be too granular, so it is necessary to ensure that the solvent added is qualified and can meet the requirements of spraying. This requires certain pre-treatment operations before adding. Utility Model Content

[0030] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0031] See also Figure 1-8 As shown, the utility model is a heavy metal-free alkyd paint solvent adding device, comprising a storage tank 1, a cylinder 2, and a quantitative adding tube 3. A bracket 103 is fixed on the outer circumference of the storage tank 1, and two support plates 104 are also fixed on the outer circumference of the storage tank 1 below the bracket 103. The cylinder 2 is fixed in the bracket 103, and the quantitative adding tube 3 is fixed on one side of the two support plates 104 away from the storage tank 1.

[0032] The storage tank 1 is used to store the solvent required for the preparation of alkyd paint. Multiple storage tanks 1 can be set up and placed on the batching equipment for use. Different storage tanks 1 can temporarily store different solvents. The cylinder 2 is fixed by the bracket 103, and the quantitative addition cylinder 3 is fixed by the support plate 104.

[0033] A membrane filtration assembly 105 is fixed inside the storage tank 1, and a booster pump 102 is fixed at the upper end of the storage tank 1; the booster pump 102 is used to pressurize the inside of the storage tank 1, and the membrane filtration assembly 105 is used to filter the incoming solvent. The boosted filtration speeds up the filtration process, and the boosting setting can more conveniently guide the solvent below the membrane filtration assembly 105;

[0034] A shell 306 is provided inside the quantitative addition cylinder 3, and a plugging member 307 is provided in the inner cavity of the shell 306. A push rod 301 is fixed to the telescopic end of the cylinder 2 downward, and the lower part of the push rod 301 penetrates and extends into the quantitative addition cylinder 3, and the lower end of the push rod 301 penetrates the upper end of the shell 306 and is fixed to the upper end of the plugging member 307 in the shell 306;

[0035] The push rod 301 is used to control the movement of the blocking member 307, thereby controlling the movement of the housing 306, and further controlling the movement of the solvent in the quantitative addition cylinder 3 to achieve quantitative addition.

[0036] Two air pipes 1021 are fixed to the air outlet of the booster pump 102, and the ends of the two air pipes 1021 away from the booster pump 102 are respectively connected and fixed to the inside of the storage tank 1 above and below the membrane filtration assembly 105;

[0037] When the booster pump 102 is working, the output air is transported into the storage tank 1. After the solvent enters the storage tank 1, it is filtered by the membrane filter assembly 105, and the booster pump 102 is used to increase the pressure inside. Since the space above the membrane filter assembly 105 is smaller than the space below it, the pressure above the membrane filter assembly 105 is greater than that below it, but both are greater than the standard atmospheric pressure, so that it can achieve rapid filtration. At the same time, since the pressure below the membrane filter assembly 105 is also greater than the standard atmospheric pressure, it can help the solvent below the membrane filter assembly 105 to quickly enter the quantitative addition cylinder 3.

[0038] A feed pipe 101 is fixed through the center of the upper end of the storage tank 1, and a feed valve 1011 is fixed on the feed pipe 101;

[0039] The feed pipe 101 is used to input the corresponding solvent into the storage tank 1 for use, and is opened and closed in conjunction with the feed valve 1011.

[0040] A connecting pipe 305 is fixedly connected to the outer peripheral surface of the quantitative addition cylinder 3 close to the storage tank 1, and one end of the connecting pipe 305 away from the quantitative addition cylinder 3 is fixedly connected to the inside of the storage tank 1;

[0041] The solvent in the storage tank 1 enters the quantitative addition cylinder 3 through the connecting pipe 305 .

[0042] An overflow pipe 303 is fixed through the upper end of the quantitative addition cylinder 3, and the end of the overflow pipe 303 away from the quantitative addition cylinder 3 is connected to the inside of the storage tank 1, and a one-way valve 3031 is fixed on the overflow pipe 303. When there is too much solvent in the quantitative addition cylinder 3, it will be guided back to the storage tank 1 from the overflow pipe 303. However, when the storage tank 1 is draining the solvent, it will not be drained from the overflow pipe 303 due to the action of the one-way valve 3031. The passage of the one-way valve 3031 is in the direction from the quantitative addition cylinder 3 to the inside of the storage tank 1.

[0043] The outer peripheral surface of the quantitative addition cylinder 3 is also provided with a scale bar 302, and a discharge pipe 304 with a valve is fixed through the bottom of the quantitative addition cylinder 3; the quantitative addition cylinder 3 is made of transparent material, and the position of the sealing plate and the shell 306 is determined by the scale bar 302, thereby determining the amount of solvent. After determination, the solvent is added to the mixing equipment through the discharge pipe 304.

[0044] The shell 306 has vertically penetrating through slots 3061 in an annular array, and a limiting column 3062 is fixed on one side of the through slots 3061 . A limiting slot matching the size of the limiting column 3062 is formed on one side of the blocking member 307 .

[0045] The specific working principle of the utility model is as follows: first, the corresponding solvent is input into the storage tank 1 through the feed pipe 101. After the solvent enters the storage tank 1, it is filtered by the membrane filter assembly 105, and the booster pump 102 is used to increase the pressure inside the membrane filter assembly 105. Since the space above the membrane filter assembly 105 is smaller than the space below it, the pressure above the membrane filter assembly 105 is greater than that below it, but both are greater than the standard atmospheric pressure, so that rapid filtration can be achieved. At the same time, since the pressure below the membrane filter assembly 105 is also greater than the standard atmospheric pressure, the solvent below the membrane filter assembly 105 can be helped to quickly pass through the connecting pipe 305 and enter the quantitative addition cylinder 3;

[0046] Secondly, the quantitative addition cylinder 3 is made of transparent material. The positions of the sealing plate and the shell 306 are determined in advance by the scale bar 302. The heights of the sealing member 307 and the shell 306 are adjusted by the cylinder 2. After the agent enters the quantitative addition cylinder 3 and reaches the required amount, the push rod 301 is rotated to make the sealing member 307 seal the through groove 3061 in the shell 306. Then the cylinder 2 is operated to push the sealing member 307 and the shell 306 downward, so that the solvent under the two can be pushed out, and the solvent can be discharged from the discharge pipe 304 to achieve quantitative addition.

[0047] The above are only preferred embodiments of the present invention and do not limit the present invention. Any modification to the technical solutions recorded in the aforementioned embodiments and any equivalent replacement of some of the technical features therein, any modification, equivalent replacement, and improvement made are all within the protection scope of the present invention.
