Description

Technical Field

[0001] The utility model relates to the technical field of homogenizing equipment, in particular to a homogenizing valve adopting a novel collision model. Background Art

[0002] Homogenization is the process of making dispersed materials in fluid into microparticles and homogenize them. The mainstream homogenization equipment in the prior art adopts the Y-type homogenization valve, where the Y-type refers to Figure 1 As shown, a Y-shaped flow channel is set in the valve body, and the fluid flows in from the feed port on the valve body and enters the two branches respectively. The fluids of the two branches meet at the end and collide with each other and finally discharge from the outlet on the valve body through the third branch, thereby achieving homogenization of the slurry. With the continuous development of homogenization technology, the requirements for homogenization performance in some fields are getting higher and higher. For example, in the field of graphene, as far as the existing Y-type homogenizing valve is concerned, the homogenization effect of the fluid after one collision is not good, and it is generally necessary to repeat the homogenization process. Therefore, the overall homogenization efficiency is low, which is also one of the important reasons for the high production cost. Utility Model Content

[0003] The utility model aims to solve one of the technical problems in the related art to at least a certain extent: to provide a homogenizing valve adopting a new collision model, which can achieve more efficient collision by changing the fluid collision model, thereby reducing the number of repeated collisions in the homogenization process and improving production efficiency.

[0004] To this end, one purpose of the utility model is to propose a homogenous valve adopting a new collision model, comprising a valve body with an interactive cavity inside, a discharge channel with one end connected to the interactive cavity and the other end extending to the outside of the valve body, and at least three injection channels arranged around the interactive cavity, the center line of each injection channel and the center line of the discharge channel intersect at a theoretical collision point O in the interactive cavity, a reference plane perpendicular to the center line of the discharge channel is constructed with the theoretical collision point O as the center of the circle, each injection channel on the valve body is located on the side of the reference plane away from the discharge channel, any two adjacent injection channels are arranged at intervals along the circumferential direction of the center line of the discharge channel, and the injection channels are arranged so that the resultant force applied by each injection channel along its own center line to the theoretical collision point O is directed along the center line of the discharge channel toward the outside of the interactive cavity.

[0005] The above technical solution has the following advantages or beneficial effects: First, the traditional Y-type homogenizing valve is changed from a simple plane design of the Y-type flow channel to a three-dimensional structure design, thereby allowing multiple jets to collide at the same time. When a single jet is the same, compared with the existing Y-type homogenizing valve, multiple jets collide at the same time, so the output per unit time is high. Secondly, the use of this new collision model can make the collision surface between the jets larger, thereby improving the collision efficiency. Therefore, while meeting the same homogenization performance requirements, the number of repeated collisions can be reduced, and even one collision can meet the performance requirements.

[0006] According to an example of the utility model, there are three or more injection channels, and each injection channel is evenly arranged along the circumference of the center line of the discharge channel. The uniform arrangement along the circumference of the center line of the discharge channel allows more injection channels to be accommodated in the same valve body at the same time, and the multiple high-speed jets formed can collide with each other in the interactive cavity. Compared with the collision of two high-speed jets in the plane Y-type homogenizing valve, it not only increases the number of jets and increases the output, but also makes the collision between the multiple jets more complete, thereby improving the homogenization efficiency.

[0007] According to an example of the present utility model, there are three injection channels.

[0008] According to an example of the utility model, the injection channels are divided into at least two groups, each group has no less than two injection channels, the angle β between the center line of the injection channel and the center line of the discharge channel is 30°~90°, and the injection channels in the same group are evenly arranged along the circumference of the center line of the discharge channel, so that the angle β between each injection channel and the discharge channel in the same group is the same, and the angle β between any two injection channels and the discharge channels in different groups is different. The injection channels in the same group are evenly arranged along the circumference, so that the jets of the same group of injection channels can collide in the interactive cavity to form a unified resultant force toward the discharge channel, and because the injection angles of different groups of injection channels are different, the jets emitted by any one of the injection channels can collide with the jets of other adjacent groups synchronously on the basis of the collision of the jets in the same group, further improving the collision efficiency.

[0009] According to an example of the present utility model, there are four injection channels, and the four injection channels are divided into two groups.

[0010] According to an example of the utility model, the valve body is made of a whole piece of substrate, each injection channel on the valve body penetrates the valve body in the direction away from the interactive cavity and forms a mounting hole on the outer wall of the valve body, each mounting hole is provided with a jet generator for generating a high-speed jet, the liquid outlet end of the jet generator is detachably connected to the corresponding mounting hole, and the center line of the liquid outlet end of the jet generator is colinear with the center line of the corresponding injection channel. Compared with the Y-shaped flow channel formed by the combination of two semi-cylinders in the prior art, the valve body is made of a whole piece of substrate, so the interactive cavity, discharge channel and each injection channel in the valve body are complete, and there is no splicing gap, so it can withstand greater fluid pressure, and at the same time, the injection channel on the valve body can be machined by drilling, so the overall valve body manufacturing cost can be greatly reduced, which is ultimately conducive to industrial promotion.

[0011] According to an example of the utility model, the jet generator includes a nozzle body, the rear end of the nozzle body has an inlet connected to an external liquid supply pipe, the front end of the nozzle body is a liquid outlet, and a jewel nozzle is provided on the liquid outlet. The jewel nozzle has a liquid outlet hole connected to the nozzle body, and the aperture of the liquid outlet hole is smaller than the inner diameter of the nozzle body.

[0012] Additional aspects and advantages of the present invention will be given in part in the following description, and in part will become apparent from the following description, or will be learned through the practice of the present invention. BRIEF DESCRIPTION OF THE DRAWINGS

[0023] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and should not be construed as limiting the present invention.

[0024] The homogenizing valve using a novel collision model according to an embodiment of the utility model is described in detail below with reference to the accompanying drawings.

[0025] like Figure 1 The Y-type homogenizing valve in the prior art shown in the figure is mainly used in a working environment with a pressure of 100 MPA, which is between high pressure and ultra-high pressure. Under this pressure, the service life of the homogenizing valve can meet the existing needs, and Figure 1 The flow channel of the homogenizing valve shown includes an outflow channel connected to the liquid outlet and two inflow channels, and the two inflow channels are connected to the same liquid inlet. Therefore, after the production of the Y-type homogenizing valve is completed, the pressure in the two inflow channels can be kept consistent, and there is no need to worry about the direction of the two inflow channels. Therefore, the Y-type homogenizing valve of the prior art has its own advantages under the working environment of 100MPA.

[0026] However, with the increasing requirements for fluid pressure in the homogenization process in various industries, especially when the fluid is a slurry medium with solid particles, the existing Y-type homogenizing valve will have obvious problems of low service life and high manufacturing cost, which is particularly prominent in the graphene industry.

[0027] Based on the consideration of reducing processing costs and improving homogenization efficiency, the utility model provides a homogenization valve structure adopting a new collision model, such as Figure 2As shown, the homogenizing valve includes a valve body 1 with an interactive cavity 2 inside, a discharge channel 3 with one end connected to the interactive cavity 2 and the other end extending to the outside of the valve body 1, and at least three injection channels 4 arranged around the interactive cavity 2, the center line of each injection channel 4 and the center line of the discharge channel 3 intersect at a theoretical collision point O in the interactive cavity 2, and a reference plane S perpendicular to the center line of the discharge channel 3 is constructed with the theoretical collision point O as the center of the circle, each injection channel 4 on the valve body 1 is located on the side of the reference plane away from the discharge channel 3, any two adjacent injection channels 4 are arranged at intervals along the circumferential direction of the center line of the discharge channel 3, and the injection channels 4 are arranged so that the resultant force applied by each injection channel 4 along its own center line on the theoretical collision point O is directed along the center line of the discharge channel 3 toward the outside of the interactive cavity 2.

[0028] In this embodiment, the discharge channel 3 is located below the reference plane S, and all the injection channels 4 are arranged above the reference plane S, so that each injection channel 4 is directed obliquely downward toward the theoretical collision point O in the interactive cavity 2. When the high-speed jets in each injection channel 4 intersect at the theoretical collision point along the center lines of their respective injection channels, a collision occurs, thereby achieving a homogenization effect. At the same time, the fluids after the collision can form a combined force downward along the center line of the discharge channel, so that the fluids can flow downward along the center line of the discharge channel after merging until they are discharged from the valve body 1.

[0029] Based on one of the preferred examples of the injection channel 4 in the above embodiment:

[0030] There are three or more injection channels 4, and each injection channel 4 is evenly arranged along the circumference of the center line of the discharge channel 3. At the same time, the angle β between the center line of each injection channel 4 and the center line of the discharge channel 3 is the same, and the design range of the angle β is 30°~90°. Since the multiple injection channels 4 are all at the same inclination angle and are evenly arranged around the circumference of the center line of the discharge channel 3, it can be ensured that when each injection channel 4 injects the same jet, each jet can be discharged together downward along the discharge channel 3 after colliding with each other at the theoretical collision point O. In this embodiment, the angle β refers to an angle less than or equal to 90° formed by the center line of the injection channel 4 and the straight line where the center line of the discharge channel 3 is located.

[0031] Specifically, Figure 3 and Figure 4 As shown, there are three injection channels 4. Figure 3 and Figure 4Taking the case where there are three injection channels 4 in the middle valve body as an example, the preferred collision position of any two adjacent jets is the adjacent inner area M. It is not difficult to see that there are three collision areas M. Therefore, compared with the existing Y-type homogenizing valve, during the collision process after the two injection channels are arranged in a Y-shape, the two jets have only one inner collision area. Therefore, this embodiment is significantly superior to the Y-type homogenizing valve in the prior art in terms of homogenization efficiency.

[0032] Based on the second preferred example of the injection channel 4 in the above embodiment:

[0033] like Figure 5 As shown, the injection channels 4 are divided into at least two groups, each group has at least two injection channels 4, the angle β between the center line of the injection channel 4 and the center line of the discharge channel 3 is 30° to 90°, and the injection channels 4 in the same group are evenly arranged along the circumference of the center line of the discharge channel 3, so that the angle β between each injection channel 4 and the discharge channel 3 in the same group is the same, and the angle β between any two injection channels 4 and the discharge channel 3 in different groups is different. In this embodiment, the angle β refers to the angle less than or equal to 90° formed by the center line of the injection channel 4 and the straight line where the center line Z of the discharge channel 3 is located.

[0034] Specifically, Figure 5 As shown, there are four injection channels 4, and the center lines of the four injection channels 4 are L1, L2, L3, and L4 in the figure, respectively. The four injection channels 4 are divided into two groups, of which L1 and L2 are the first group, and L3 and L4 are the second group. The angle β between the center line L1 and the center line L2 in the first group and the center line Z of the discharge channel 3 is 60°, and the angle β between the center line L3 and the center line L4 in the second group and the center line Z of the discharge channel 3 is 30°. At this time, the two identical jets injected along the center line L1 and the center line L2 in the vertical plane formed by the center line L1, the center line L2 and the center line Z can collide at the theoretical collision point O, and form a resultant force downward along the center line Z after the collision. Similarly, the other two identical jets injected along the center line L3 and the center line L4 in another vertical plane formed by the center line L3, the center line L4 and the center line Z can also collide at the theoretical collision point O, and form a resultant force downward along the center line Z after the collision. At this time, since the angles β of the two groups of injection channels 4 are designed differently, the jet from any injection channel 4 can have more collision contact surfaces with the jet from the adjacent injection channel in the other group, and more contact surfaces also mean more sufficient collision contact, ultimately achieving a better homogenization effect.

[0035] For the preparation of each injection channel and outflow channel in the homogenizing valve, the existing Y-type homogenizing valve is as follows: Figure 1As shown, the valve body is formed by splicing two semi-cylindrical valve bodies together. The disadvantages of using the existing homogenizing valve processing method are obvious. On the one hand, for the situation where the fluid pressure continues to increase, the manufacturing accuracy of the two semi-cylindrical valve bodies and the assembly accuracy of the mutual cooperation are required to be high. The upper limit of the pressure that the currently known Y-type homogenizing valve can meet is about 200MPA. At the same time, it is precisely because of the difficulty in the manufacturing process of the homogenizing valve that its manufacturing cost is relatively high. According to the current market price, the price of the existing Y-type homogenizing valve that can meet the use of 200MPA fluid is generally tens of thousands to hundreds of thousands of yuan, and the Y-type homogenizing valve is a consumable part, and its effective use time is generally within 2000 hours. Therefore, in various industries that use the homogenizing valve for production and processing, there is a common problem of high production costs. To this end, the improvement of this embodiment is that: the valve body 1 is made of a whole base material, that is, the injection channel 4 and the discharge channel in the valve body 1 are formed by drilling or boring and milling, and each injection channel 4 on the valve body 1 passes through the valve body 1 in the direction away from the interactive chamber 2 and forms a mounting hole 5 located on the outer wall of the valve body 1. Each mounting hole 5 is provided with a jet generator 6 for generating a high-speed jet, and the liquid outlet end 6.3 of the jet generator 6 is detachably connected to the corresponding mounting hole 5, and the center line of the liquid outlet end 6.3 of the jet generator 6 is colinear with the center line of the corresponding injection channel 4. It is worth mentioning that it is precisely the widespread use of the Y-type homogenizing valve in the existing industry and the processing method of the Y-type homogenizing valve using two semi-cylindrical valve bodies to form the flow channel in the valve that makes the injection channels in the valve body designed in the same vertical plane.

[0036] It can be learned from the above process that the jet generator 6 is an external component, and its liquid outlet end 6.3 has the function of ejecting fluid. At the same time, the liquid outlet end 6.3 can be detachably connected with the corresponding mounting hole 5 on the valve body. The detachable connection method includes but is not limited to that the liquid outlet end 6.3 has an external thread, and the mounting hole 5 has an internal thread. The liquid outlet end 6.3 of the jet generator 6 is threadedly connected to the mounting hole 5.

[0037] Based on the preferred embodiment of the jet generator 6, the jet generator 6 includes a nozzle body 6.1, the rear end of the nozzle body 6.1 has an inlet 6.2 connected to an external liquid supply pipe, the front end of the nozzle body 6.1 is a liquid outlet 6.3, and a jewel nozzle 6.4 is provided on the liquid outlet 6.3, and the jewel nozzle 6.4 has a liquid outlet hole 6.5 connected to the nozzle body 6.1, and the aperture of the liquid outlet hole 6.5 is smaller than the inner diameter of the nozzle body 6.1. Specifically, the inlet 6.2 at the rear end of the jet generator 6 is connected to the liquid supply pipe, and the liquid supply pipe is connected to an external feed pump, and the fluid to be homogenized is pressurized and pumped into the jet generator 6 by the feed pump.

[0038] In the above embodiments, the fluid is a liquid containing particles or macromolecular substances. Preferably, in the graphene powder preparation process, the fluid is preferably a slurry containing graphite particles.

[0039] The jet in the above embodiments refers to a columnar jet formed by ejecting fluid from a small hole at a pressure exceeding 100 MPA, that is, a high-speed fluid. Taking the graphene field as an example, the diameter of the high-speed fluid is generally 0.1~0.4mm, and the flow rate is generally greater than 100m / s.

[0040] Although the embodiments of the present invention have been shown and described above, it can be understood that the above embodiments are exemplary and cannot be understood as limitations of the present invention. Ordinary technicians in the field can change, modify, replace and modify the above embodiments within the scope of the present invention.

[0041] For those skilled in the art, various changes and modifications will undoubtedly be obvious after reading the above description. Therefore, the attached claims should be regarded as covering all changes and modifications to the true intent and scope of the utility model. Any and all equivalent ranges and contents within the scope of the claims should be considered to still be within the intent and scope of the utility model.
