[0021] It should be noted that, in this document, relational terms such as "first" and "second" are used merely to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. In this document, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Without further limitations, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes that element.

[0022] The inventors of this solution discovered that existing homogenizers have relatively low flow rates, which cannot meet users' production capacity requirements. This embodiment provides the following solution:

[0023] like Figures 1 to 2 As shown, this embodiment provides a dual-plunger pump homogenizer, including a first plunger pump 1, a second plunger pump 2, a feed pipeline 3, and a homogenization chamber assembly 4. The feed pipeline 3 includes a feed pipe 31, a three-way pipe 32, a first high-pressure three-way valve 33, a second high-pressure three-way valve 34, and a third high-pressure three-way valve 35. The first port of the three-way pipe 32 is connected to the feed pipe 31, the second port of the three-way pipe 32 is connected to the first port of the first high-pressure three-way valve 33, and the third port of the three-way pipe 32 is connected to the first port of the second high-pressure three-way valve 34. The second port of the first high-pressure three-way valve 33 is connected to the output end of the first plunger pump 1, and the second port of the second high-pressure three-way valve 34 is connected to the output end of the second plunger pump 2. The third port of the first high-pressure three-way valve 33 is connected to the first port of the third high-pressure three-way valve 35 via a pipeline, the third port of the second high-pressure three-way valve 34 is connected to the second port of the third high-pressure three-way valve 35 via a pipeline, and the third port of the third high-pressure three-way valve 35 is connected to the homogenization chamber assembly 4 via a pipeline.

[0024] It should be noted that after the material is input from the feed pipe 31, it passes through the three-way pipe 32 and then through the first high-pressure three-way valve 33 and the second high-pressure three-way valve 34 respectively. The flow rate of the material is then increased by the first plunger pump 1 and the second plunger pump 2 respectively. The flow rate can also be regulated and controlled by the first high-pressure three-way valve 33 and the second high-pressure three-way valve 34. Finally, the material is homogenized by the third high-pressure three-way valve 35 and the homogenization chamber group 4, thereby greatly improving the flow rate and controllability.

[0025] In some embodiments, the conveying pipeline 3 further includes a first bend 36, a second bend 37, a first vertical pipe 38, and a second vertical pipe 39. The two ends of the first bend 36 are respectively connected to the second port of the tee pipe 32 and one end of the first vertical pipe 38. The two ends of the second bend 37 are respectively connected to the third port of the tee pipe 32 and one end of the second vertical pipe 39. The other end of the first vertical pipe 38 is connected to the first port of the first high-pressure tee valve 33, and the other end of the second vertical pipe 39 is connected to the first port of the second high-pressure tee valve 34.

[0026] It should be noted that by setting the first bend 36, the second bend 37, the first vertical pipe 38, and the second vertical pipe 39, the volume of the pipeline can be significantly reduced, thereby reducing the overall volume of the homogenizer.

[0027] In some embodiments, a first check valve 301 is connected between the other end of the first vertical pipe 38 and the first port of the first high-pressure three-way valve 33, and a second check valve 302 is connected between the other end of the second vertical pipe 39 and the first port of the second high-pressure three-way valve 34. A third check valve 303 is connected between the third port of the first high-pressure three-way valve 33 and the first port of the third high-pressure three-way valve 35, and a fourth check valve 304 is connected between the third port of the second high-pressure three-way valve 34 and the second port of the third high-pressure three-way valve 35.

[0028] It should be noted that the first check valve 301 and the third check valve 303 can prevent material backflow at one end of the conveying pipeline 3, thereby ensuring the normal operation of the homogenizer and also preventing damage to the first plunger pump 1. The second check valve 302 and the fourth check valve 304 can prevent material backflow at the other end of the conveying pipeline 3, thereby ensuring the normal operation of the homogenizer and also preventing damage to the second plunger pump 2.

[0029] In some embodiments, the first plunger pump 1 and the second plunger pump 2 each include a housing 121, a plunger rod 122, a first fixing plate 123, a second fixing plate 124, and a cylinder 125. The housing 121 is mounted on the first fixing plate 123, and the first fixing plate 123 is connected to the second fixing plate 124 through a plurality of fixing posts 126. The plunger rod 122 is located between the first fixing plate 123 and the second fixing plate 124. The cylinder 125 is mounted on the second fixing plate 124, and the output end of the cylinder 125 is connected to the plunger rod 122.

[0030] In some embodiments, the first fixing plate 123 and the second fixing plate 124 are both square in shape, and the fixing columns 126 are evenly distributed in a circumferential array, thereby ensuring the stability of the first plunger pump 1 and the second plunger pump 2 during operation.

[0031] In some embodiments, a pressure gauge 5 is provided on the pipeline connecting the third port of the third high-pressure three-way valve 35 to the homogenizing chamber group 4, so that the pressure in the pipeline can be detected in real time, making the homogenization operation more controllable.

[0032] In some embodiments, a needle valve 6 is provided on the pipe connecting the third port of the third high-pressure three-way valve 35 to the homogenizing chamber group 4. One end of the needle valve 6 is connected to the homogenizing chamber group 4, and the other end of the needle valve 6 is connected to an exhaust pipe 61, thereby enabling precise control of the material output flow rate.

[0033] In some embodiments, the homogenization chamber assembly 4 includes a first high-pressure valve 41, a second high-pressure valve 42, at least one diamond interactive cavity main chamber 43, and at least one diamond interactive cavity secondary chamber 44. The first high-pressure valve 41, the diamond interactive cavity main chamber 43, the diamond interactive cavity secondary chamber 44, and the second high-pressure valve 42 are connected in sequence, and one end of the first high-pressure valve 41 is connected to the needle valve 6 through a pipe.

[0034] Specifically, two diamond interactive cavity main cavities 43 and two diamond interactive cavity secondary cavities 44 are used. The cooperation between the diamond interactive cavity main cavity 43 and the diamond interactive cavity secondary cavities 44 improves the homogenization effect of materials.

[0035] In some embodiments, one end of the second high-pressure valve 42 is connected to a material exchanger 8 via a safety valve 7. The material exchanger 8 is provided with a discharge port 81, and the safety valve 7 is provided with a pressure relief port 71.

[0036] It should be noted that the material exchanger 8 can regulate the temperature of the material, thereby improving the homogenization effect. The safety valve 7 can prevent the pressure from exceeding the upper limit during operation, thus protecting the safety of the equipment and personnel.

[0037] In summary, the embodiments of this utility model provide a dual-plunger pump homogenizer, which is equipped with two plunger pumps and corresponding conveying pipelines. The conveying pipelines are equipped with corresponding high-pressure valves and check valves, thereby increasing the overall flow rate of the homogenizer and also increasing the stability and controllability of the conveying process.
