[0036] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0037] The present invention will now be further described in conjunction with the accompanying drawings and specific embodiments:

[0038] like Figure 1 , 2 As shown, a defoamer testing device includes a base 1, an installation chamber 10 is provided in the base 1, and a liquid adding component 2, a defoamer adding component 3, a draining component 4, an air blowing component 5 and a heating component 6 are provided in the installation chamber 10.

[0039] A reference measuring cylinder 7 and a test measuring cylinder 8 are arranged opposite each other on the base 1. The lower ends of the reference measuring cylinder 7 and the test measuring cylinder 8 are placed in the installation chamber 10 and are provided with a drain port 20.

[0040] The heating component 6 is connected to the lower ends of the reference measuring cylinder 7 and the test measuring cylinder 8.

[0041] The liquid addition component 2 is used to add cleaning water or an equal amount of water-based ink to the reference measuring cylinder 7 and the test measuring cylinder 8, respectively.

[0042] The defoamer adding component 3 is used to add a set amount of defoamer to the test measuring cylinder 8;

[0043] The drain assembly 4 is connected to the drain ports 20 of the reference measuring cylinder 7 and the test measuring cylinder 8 respectively, and is used to drain the liquid in the reference measuring cylinder 7 and the test measuring cylinder 8.

[0044] The aeration assembly 5 is used to simultaneously aerate the water-based ink in the reference measuring cylinder 7 and the test measuring cylinder 8 at regular intervals and in a quantitative manner.

[0045] In this embodiment, during operation, equal amounts of water-based ink are first added to the reference measuring cylinder 7 and the test measuring cylinder 8 through the liquid adding component 2. Then, a set amount of defoamer is added to the test measuring cylinder 8 through the defoamer adding component 3. The water-based ink in the reference measuring cylinder 7 and the test measuring cylinder 8 is heated to a set temperature through the heating component 6. Then, the water-based ink in the reference measuring cylinder 7 and the test measuring cylinder 8 is aerated simultaneously through the aeration component 5 at regular intervals and in a quantitative manner. The aeration causes the water-based ink to foam. After completion, the foam height of the reference measuring cylinder 7 and the test measuring cylinder 8 are observed respectively. The performance of the defoamer is judged based on the foam height of the two measuring cylinders. The process is convenient and simple to operate.

[0046] The above structure uses the heating component 6 to bring the temperature of the water-based ink in the reference measuring cylinder 7 and the test measuring cylinder 8 close to the actual production temperature, and uses the air blowing component 5 to bring the water-based ink in the reference measuring cylinder 7 and the test measuring cylinder 8 close to the shaking or stirring during actual production. This can accurately simulate the actual production environment and effectively ensure the accuracy of the test results. At the same time, it makes the amount of water-based ink added, the temperature, and the air blowing impact force the reference measuring cylinder 7 and the test measuring cylinder 8 the same, which facilitates intuitive and rapid accurate comparison.

[0047] In this embodiment, in order to clean the reference measuring cylinder 7 and the test measuring cylinder 8 after the test is completed, cleaning water can be added to the reference measuring cylinder 7 and the test measuring cylinder 8 respectively by adding components to clean them, and the waste liquid after cleaning can be discharged by the draining component 4.

[0048] Furthermore, such as Figure 1 , 2 As shown, in order to achieve automatic completion of adding, heating and aeration, a control module 30 is also included. The control module 30 is equipped with a touch screen (not shown in the figure) and / or buttons (not shown in the figure). The control module 30 is electrically connected to the liquid adding component 2, the defoamer adding component 3, the liquid draining component 4, the aeration component 5 and the heating component 6 respectively.

[0049] During operation, the testing device can be started via the touch screen or buttons. The testing device can then automatically perform operations such as adding water-based ink and defoamer, heating, and blowing according to the control program built into the control module 30.

[0050] Furthermore, such as Figure 1 As shown, the liquid addition assembly 2 includes a first pump body 21 disposed in the installation chamber 10. The inlet end of the first pump body 21 is provided with a first inlet pipe 22, and the outlet end is provided with a first liquid addition pipe 23 and a second liquid addition pipe 24 respectively.

[0051] The first liquid addition tube 23 and the second liquid addition tube 24 are respectively provided with a first valve 25 and a second valve 26, and the other ends of the first liquid addition tube 23 and the second liquid addition tube 24 are respectively placed in the reference measuring cylinder 7 and the test measuring cylinder 8.

[0052] The first valve 25 and the second valve 26 are located inside the installation chamber 10.

[0053] In this embodiment, when adding water-based ink, equal amounts of water-based ink are added to the reference measuring cylinder 7 and the test measuring cylinder 8 by controlling the opening and closing of the first valve 25 and the second valve 26 respectively; during cleaning, the first valve 25 and the second valve 26 can be opened simultaneously to add cleaning water to the reference measuring cylinder 7 and the test measuring cylinder 8.

[0054] Furthermore, such asFigure 1 As shown, in order to avoid water-based ink falling directly into the bottom of the measuring cylinder and causing foam that would affect the test results, the outlet ends of the first liquid addition tube 23 and the second liquid addition tube 24 are respectively attached to the inner walls of the reference measuring cylinder 7 and the test measuring cylinder 8.

[0055] Furthermore, such as Figure 1 As shown, in order to achieve automatic addition of defoamer, the defoamer addition component 3 includes a second pump body 31 disposed in the installation chamber 10, the inlet end of the second pump body 31 is provided with a second inlet pipe 32, and the outlet end is provided with a third addition pipe 33.

[0056] The other end of the third liquid addition tube 33 is placed inside the test measuring cylinder 8 and is attached to the inner wall of the test measuring cylinder 8.

[0057] Furthermore, such as Figure 1 As shown, the air-blowing assembly 5 includes two air-blowing pumps 51. The air outlet of the air-blowing pump 51 is provided with an exhaust pipe 52, and the other end of the exhaust pipe 52 extends to the lower end of the interior of the reference measuring cylinder 7 and the test measuring cylinder 8, respectively.

[0058] In this embodiment, a blower pump 51 is configured in both the reference measuring cylinder 7 and the test measuring cylinder 8. By controlling the operation of the two blower pumps 51 simultaneously, the water-based ink in the reference measuring cylinder 7 and the test measuring cylinder 8 are blown with air at the same time, ensuring that the water-based ink in the two measuring cylinders is subjected to the same impact force of air blowing, thereby improving the accuracy of the test.

[0059] Furthermore, such as Figure 1 As shown, in order to better simulate the actual foam generation situation, the air blowing assembly 5 also includes an air stone 53 placed in the reference measuring cylinder 7 and the test measuring cylinder 8. The end of the exhaust pipe 52 away from the air blowing pump 51 is connected to the air stone 53. The air stone 53 refines the air output by the air blowing pump 51, generating more distributed and more numerous bubbles in the water-based ink, producing more and more uniform foam, which can better simulate the actual production situation.

[0060] Furthermore, the heating assembly 6 includes heating sleeves 61 respectively fitted onto the bottom of the reference measuring cylinder 7 and the test measuring cylinder 8.

[0061] In this embodiment, the two heating sleeves 61 work simultaneously to heat the water-based ink in the reference measuring cylinder 7 and the test measuring cylinder 8 to the set temperature; at the same time, temperature sensors can be set to detect the temperature of the water-based ink in the reference measuring cylinder 7 and the test measuring cylinder 8 respectively, so as to achieve precise temperature control.

[0062] Furthermore, such as Figure 1 As shown, in order to automatically discharge the waste liquid from the measuring cylinder, the draining assembly 4 includes a draining pipe 41 connected to the drain port 20 of the reference measuring cylinder 7 and the test measuring cylinder 8, and a draining valve 42 disposed on the draining pipe 41.

[0063] Furthermore, such as Figure 1 , 2 As shown, the scales of the reference measuring cylinder 7 and the test measuring cylinder 8 are located close to each other, and two auxiliary observation components 9 are provided between the reference measuring cylinder 7 and the test measuring cylinder 8.

[0064] The auxiliary observation component 9 includes a connecting rod 91, a slider 92, and a beam generator 93;

[0065] One end of the connecting rod 91 is connected to the base 1, and the connecting rod 91 is arranged parallel to the reference measuring cylinder 7;

[0066] The slider 92 is slidably sleeved with the connecting rod 91. A locking member 94 is provided on the slider 92. The locking member 94 is used to restrict the degree of freedom of the slider 92 relative to the connecting rod 91 when locking.

[0067] The beam generator 93 is connected to the slider 92, and the beam generator 93 horizontally projects a light spot onto the scale of the reference measuring cylinder 7 or the test measuring cylinder 8.

[0068] In this embodiment, during the test, after the air is blown out, the height of the slider 92 is adjusted by the locking member 94 according to the height of the foam in the measuring cylinder until the light spot projected by the beam generator 93 falls on the scale corresponding to the highest position of the foam. Thus, the scale reading can be accurately observed with the help of the light spot, effectively avoiding observation errors.

[0069] For those skilled in the art, various other corresponding changes and modifications can be made based on the technical solutions and concepts described above, and all such changes and modifications should fall within the protection scope of the claims of this utility model patent.
