Description

Technical Field

[0001] This application relates to the field of material crushing equipment technology, and in particular to a homogenizer. Background Technology

[0002] In the field of homogenization equipment, existing equipment is mainly divided into two categories: one is the wall-impact type (also known as a high-pressure homogenizer), and the other is the fixed-flow-channel impact type (also known as a micro-jet homogenizer). Among them, the fixed-flow-channel impact homogenizer has poor adaptability to materials with different physical properties because the cavity channel size is fixed and cannot be dynamically adjusted.

[0003] Specifically, during high-pressure homogenization, as the particle size of the material decreases, the specific surface area and viscosity increase exponentially, and the flow resistance changes drastically. Especially for slender materials with large aspect ratios, such as nanocellulose and carbon nanotubes, or for emulsion dispersion systems, the microjet cavity with fixed channel size is prone to blockage, which directly limits the application scenarios and applicable material range of the equipment.

[0004] To address the aforementioned issues, we developed an adjustable valve core-seat spacing homogenizer. While this type of equipment achieves the function of spacing adjustment, it faces the challenge of sealing between the moving valve core and the homogenizing valve body: during the adjustment process or long-term operation, leakage is prone to occur at the sealing interface between the valve core and the valve seat, thereby affecting the stability of the homogenizing pressure and the final homogenization effect. Utility Model Content

[0024] Reference Figures 1 to 9This application discloses a homogenizer, which includes a first valve body 100, a valve seat 200, and a valve core 300. The first valve body 100 is provided with a first homogenization channel 110. The valve seat 200 is installed at the feed end of the first homogenization channel 110. The valve core 300 is slidably installed in the first homogenization channel 110. The valve core 300 can adjust the distance between the valve seat 200 and the valve core 300 by sliding along the first homogenization channel 110. The valve seat 200 is provided with at least one through hole, and the valve core 300 is provided with a discharge hole 310. The material at the feed end of the first homogenization channel 110 passes through the through hole and through the valve seat 200. Then, after colliding between the valve seat 200 and the valve core 300, it enters the discharge hole 310 and flows to the discharge end of the first homogenization channel 110 through the discharge hole 310.

[0025] It should be noted that the valve core 300 can slide linearly or rotate along the first homogeneous channel 110.

[0026] Because the distance between the valve core 300 and the valve seat 200 is adjustable, and the valve core 300 and the valve seat 200 are not directly connected, material leakage is likely to occur during collision. To reduce the occurrence of such accidents, in the embodiments of this application, reference is made to... Figure 3 As shown, the valve core 300 is fitted with a sealing structure 400, which is installed inside the first homogenization channel 110 and the inner wall of the first homogenization channel 110 is sealed. By setting the sealing structure 400, material leakage can be prevented, and the stability of the homogenization pressure and the homogenization effect can be ensured.

[0027] In some specific embodiments of this application, the sealing structure 400 is made of a flexible material, and can adopt structures such as sealing rings and fillers according to actual conditions, preferably made of materials such as high molecular weight polyethylene and PEEK. The sealing structure 400 is installed between the inlet end and the outlet end of the first homogenizing channel 110, preferably between the valve core 300 and the first homogenizing channel 110. The sealing structure 400 can be installed at the end or middle of the valve core 300, for example, the sealing structure 400 can be installed at... Figure 3 The valve core 300 shown can be installed at one end near the valve seat 200, or at the end away from the valve seat 200, or at the middle position of the valve core 300; this embodiment is not limited to any particular position. The sealing structure 400 can be a single part or a combination of multiple parts, and can be specifically set according to the actual situation; this embodiment is not limited to any particular position.

[0028] In some embodiments of this application, material collides with the valve seat 200 and the valve core 300 to achieve crushing. The material can be focused on one point for collision or focused on multiple points for collision. The end face of the valve seat 200 facing the valve core 300 and the end face of the valve core 300 facing the valve seat 200 can both be flat, or the end faces of the valve seat 200 and / or the valve core 300 can be provided with annular or polygonal protrusions, so that the material... Figure 5 As shown, they collide at the extension of the axis of the valve seat 200 and / or the valve core 300.

[0029] The end face of valve seat 200 facing valve core 300 and the end face of valve core 300 facing valve seat 200 can also be provided with a flow guiding structure to improve the collision effect. For example, the end face of valve seat 200 facing valve core 300 is provided with multiple flow guiding grooves 800, and / or the end face of valve core 300 facing valve seat 200 is provided with multiple flow guiding grooves 800. The axes of the multiple flow guiding grooves 800 intersect within the projection range of the discharge hole 310. The material collides at the intersection point of the axes of the flow guiding grooves 800 and then enters the discharge hole 310. In specific embodiments, multiple guide grooves 800 may be provided on the end face of the valve seat 200 facing the valve core 300, while no guide grooves 800 may be provided on the end face of the valve core 300 facing the valve seat 200; or multiple guide grooves 800 may be provided on the end face of the valve seat 200 facing the valve core 300, and multiple guide grooves 800 may also be provided on the end face of the valve core 300 facing the valve seat 200; or no guide grooves 800 may be provided on the end face of the valve seat 200 facing the valve core 300, while multiple guide grooves 800 may be provided on the end face of the valve core 300 facing the valve seat 200.

[0030] Furthermore, the flow guide 800 can be referenced. Figure 6 , Figure 7 The pattern shown is used for configuration, but the axes of multiple guide channels 800 can have one or more intersection points. The intersection point of the axes of the guide channels 800 is the collision point of the material. For example, Figure 6 The axes of the multiple guide grooves 800 shown intersect on the extended lines of the axes of the valve seat 200 and / or the valve core 300. The number of guide grooves 800 can be set to... Figure 6 The three shown can also be set to two, four, five, six, seven, eight, etc., depending on the requirements, and are not limited in this embodiment. When the axes of multiple guide channels 800 have only one intersection point, the intersection point is usually located at the axis of the discharge hole 310. The multiple guide channels 800 can be in the shape of a straight line, a cross, a star, etc.

[0031] Figure 7 The axes of the multiple guide channels 800 shown have multiple intersection points. The multiple guide channels 800 are arranged in pairs. The axes of the multiple guide channels 800 can be set to have three intersection points, four intersection points, five intersection points, six intersection points, seven intersection points, eight intersection points, etc., which are not limited in this embodiment.

[0032] Furthermore, Figure 8 In the illustrated embodiment, the end faces of the valve seat 200 and / or valve core 300 are provided with multiple collision structures, which can be adopted using... Figures 5 to 7 Any one of the colliding structures and its variants, or a combination of multiple colliding structures and their variants. For example, with Figure 8 Taking a four-collision structure as an example, all four collision structures can use Figure 5 In actual production, all four collision structures shown in the diagram can also be implemented using the same structure. Figure 6 or Figure 7 The structure shown; similarly, four colliders can also use one Figure 5 The structure shown is one Figure 6 The structure shown has two Figure 7 The structure shown is an example of such a scheme; or two schemes can be used. Figure 6 The structure shown has two Figure 7 The scheme shown; or using four Figure 6 Variant schemes of the structure shown, such as four colliders each with two... Figure 6 The guide channel 800 shown has three Figure 6 The guide channel 800 shown has four Figure 6 The guide channels shown are 800 and five. Figure 6 The shown flow channel 800 and other schemes. Figure 8 It is not limited to setting four collision structures; it can also set two, three, five, or six collision structures, etc.

[0033] In some embodiments of this application, the valve core 300 is provided with one or more discharge holes 310. As can be seen from the above, materials can collide at a single point or multiple points on the valve seat 200 and the valve core 300. The number of discharge holes 310 can be less than the number of material collision points, or the number of discharge holes 310 can be equal to the number of material collision points. For example, the material can have multiple collision points between the valve seat 200 and the valve core 300, but the valve core 300 is only provided with one discharge hole 310; or, the material can have multiple collision points between the valve seat 200 and the valve core 300, and multiple discharge holes 310 are provided corresponding to the collision points, with multiple discharge holes 310 corresponding one-to-one with multiple collision points; or, the material can have multiple collision points between the valve seat 200 and the valve core 300, such as three collision points, but the valve core 300 is only provided with two discharge holes 310, etc. The scheme of multiple collision points and multiple discharge holes 310 can be applied to situations where a large flow of material flows in the first homogenizing channel 110. After the large flow of material collides, it is discharged through multiple discharge holes 310, which can reduce mutual interference between materials and improve the flow efficiency of materials.

[0034] In some embodiments of this application, Figures 5 to 8The valve core 300 shown has a circular outer periphery. However, in actual production, the cross-sectional shape of the valve core 300 is not limited to a circle; it can also be one or more of a polygon or an ellipse. Similarly, the valve seat 200 can also have a cross-sectional shape of one or more of a circle, a polygon, or an ellipse. And / or, the cross-sectional shape of the discharge hole 310 can be one or more of a circle, a polygon, or an ellipse. Specifically, a valve core 300 with a circular cross-sectional shape is easier to manufacture, has higher manufacturing precision, and lower cost. A valve core 300 with a polygonal or elliptical cross-sectional shape is less prone to axial rotation, thus avoiding wear caused by relative rotation between the valve core 300 and the valve seat 200, and improving the adjustment precision of the valve core 300. The cross-sectional shape and diameter of the discharge hole 310 can be flexibly set according to actual needs and are not limited in this embodiment.

[0035] In some embodiments of this application, reference is made to Figure 1 , Figure 2 As shown, the homogenizer also includes an adjustment structure 500, a drive structure 600, and a connecting structure 700. The adjustment structure 500 is movably mounted on the first valve body 100 and abuts against the valve core 300. The adjustment structure 500 moves relative to the first valve body 100 to drive the valve core 300 to slide relative to the valve seat 200, thereby adjusting the distance between the valve core 300 and the valve seat 200. The drive structure 600 drives the adjustment structure 500 to move relative to the first valve body 100, thereby driving the valve core 300 to move relative to the valve seat 200. The connecting structure 700 connects the first valve body 100 and the drive structure 600. Specifically, the drive structure 600 can be a motor, cylinder, hydraulic cylinder, or other equipment. In actual production, a motor, such as a servo motor or stepper motor, is preferred to achieve more precise distance adjustment.

[0036] In actual production practice, motors are usually used in conjunction with speed reducers. By employing appropriate speed reducers and motors, the homogenizer in this embodiment can achieve precise adjustment at the 0.001 micrometer level. The use of adjustable-pitch valve seats 200 and valve cores 300 expands the applicability of the homogenizer in this embodiment. For example, it can be used for crushing materials of different particle sizes. In the initial stage of material crushing when the material feed rate is unstable, the distance between valve seats 200 and valve cores 300 can be appropriately increased. Once the material feed rate stabilizes, the distance between valve seats 200 and valve cores 300 can be fixed to improve homogenization efficiency and quality.

[0037] In some embodiments of this application, the adjusting structure 500 is threadedly connected to the first valve body 100, and the adjusting structure 500 is equipped with a push rod 510, which abuts against the valve core 300. Specifically, refer to... Figure 2As shown, the push rod 510 enables a soft connection between the valve core 300 and the regulating structure 500, preventing the coaxiality of the regulating structure 500 and the valve core 300 from affecting the sliding of the valve core 300. The push rod 510 only abuts against the valve core 300; therefore, even if the coaxiality between the push rod 510 or the regulating structure 500 and the valve core 300 is not high, it will not affect the sliding of the valve core 300 along the homogenization channel, and the push rod 510 and the regulating structure 500 will not affect the axial sliding of the valve core 300. Conversely, because the homogenization pressure of the homogenizer is high, if the valve core 300 and the regulating structure 500 are directly connected, the coaxiality requirement between the regulating structure 500 and the valve core 300 is high to prevent the regulating structure 500 from affecting the axial movement of the valve core 300, which could lead to material leakage, damage to the valve core 300, or other malfunctions.

[0038] In some embodiments of this application, the adjusting structure 500 is threadedly connected to the first valve body 100, thus allowing the adjusting structure 500 to rotate axially. Although the push rod 510 is connected to the adjusting structure 500, it does not rotate axially with the adjusting structure 500, thereby preventing wear caused by relative rotation between the push rod 510 and the valve core 300, which would affect the service life of the equipment. In specific production practices, the adjusting structure 500 and the valve core 300 can also be directly connected according to actual needs; this is not limited in this embodiment.

[0039] In some embodiments of this application, the cross-sectional shape of the push rod 510 can be set to a circular, polygonal, elliptical or other shapes. The cylindrical push rod 510 is easy to process, has high processing accuracy and low cost, while the push rod 510 with a polygonal or elliptical cross-sectional shape is not easy to rotate axially, thereby avoiding relative rotation between the push rod 510 and the valve core 300.

[0040] In some embodiments of this application, the drive structure 600 is connected to the adjustment structure 500 via a bushing 610, and the bushing 610 and the adjustment structure 500 are connected by a pivot pin 620, which radially passes through the bushing 610 and the adjustment structure 500. Specifically, refer to... Figure 2 , Figure 4 As shown, the method of connecting the bushing 610 and the adjusting structure 500 through the shaft pin 620 is simple in structure, has good stability, high transmission efficiency, and low maintenance cost. In order to reduce the wear of the shaft pin 620 during the transmission process, the outer periphery of the shaft pin 620 is provided with a joint structure 621, which can be one or more of a bearing or a rotating bushing.

[0041] It is conceivable that in some other embodiments, the bushing 610 and the adjusting structure 500 may also be connected by fasteners such as bolts or clips.

[0042] In some embodiments of this application, the bushing 610 and the adjusting structure 500 pass through the connecting structure 700, and the connecting structure 700 radially limits the bushing 610. The connecting structure 700 includes a first end plate 710, a second end plate 720, and a connecting member 730. The first end plate 710 is connected to the driving structure 600, the second end plate 720 is connected to the first valve body 100, and the connecting member 730 connects the first end plate 710 and the second end plate 720. Specifically, refer to... Figure 1 As shown, the connecting structure 700 has a central hole for the bushing 610 to pass through axially. The first end plate 710 is connected to the drive via bolts or other fasteners, and the second end plate 720 is connected to the valve body via bolts or other fasteners. The connecting member 730 can be multiple connecting blocks, which are evenly spaced around the circumference. For example, the multiple connecting blocks can be set as follows: Figure 1 The cross shape shown facilitates the assembly and disassembly of bolts and fasteners on the first end plate 710 and the second end plate 720. In some specific embodiments, the connector 730 can also be configured as a cylindrical structure, a prismatic structure, etc.

[0043] In some embodiments of this application, the homogenizer further includes a second valve body 900, which has a second homogenization channel 910. The first homogenization channel 110 and the second homogenization channel 910 are concentric. The second homogenization channel 910 is located at the feed end of the first homogenization channel 110, and a homogenization component 920 is disposed within the second homogenization channel 910. The homogenization component 920 is used for crushing materials. Specifically, refer to... Figure 9 As shown, the second valve body 900 can pre-crush the material entering the first homogenizing channel 110, improve the uniformity of the material entering the first homogenizing channel 110, and reduce the damage of the material to the first valve body 100, valve core 300, valve seat 200 and other equipment; in addition, by setting the aperture of the second homogenizing channel 910, the feeding speed of the material entering the first homogenizing channel 110 can be controlled.

[0044] In some embodiments of this application, the aperture of the first homogenizing channel 110 may be set to be equal to or unequal to the aperture of the second homogenizing channel 910. Specifically, when the aperture of the first homogenizing channel 110 is unequal to the aperture of the second homogenizing channel 910, the through hole of the first homogenizing channel 110 may be set to be larger than the aperture of the second homogenizing channel 910, or the through hole of the first homogenizing channel 110 may be set to be smaller than the aperture of the second homogenizing channel 910.

[0045] In some specific embodiments of this application, the homogenizing component 920 restricts the material to form multiple jets, which collide at a single focus or multiple focus. For example, it can adopt the homogenizing structure in the homogenizer and the beam collision type homogenizing structure of application number CN202520852566.0, or the homogenizing structure in the multi-channel focusing collision valve structure and the homogenizing structure in the homogenizer of application number CN202521558240.3, or the homogenizing structure in the multi-dimensional jet collision valve structure and the cavity encapsulation structure of application number CN202521558241.8, etc. Other homogenizing structures can also be adopted according to actual needs, such as the homogenizing structure of valve seat 200 and valve core 300 in the embodiment of this application, etc., which are not limited in this embodiment.
