Description

Technical Field

[0001] The utility model relates to the technical field of graphene-related equipment, in particular to a graphene slurry homogenizing device. Background Art

[0002] The homogenization process of graphene refers to the process of injecting the high-speed jet formed by the pressurized graphene slurry into the interactive chamber of the homogenization valve, so that the graphene slurry collides and refines. The existing homogenization valve is mainly a Y-type homogenization valve, such as Figure 1 As shown, the existing Y-type homogenizing valve has a Y-shaped flow channel set in the valve body. The fluid flows in from the feed port on the valve body and is divided into two branches. The fluids of the two branches meet at the end and collide with each other and finally discharge from the discharge port on the valve body through the third branch. Figure 1 The bend flow channel shown, therefore, the valve body in the Y-type homogenizing valve is formed by splicing two semi-cylindrical valve bodies together. In order to meet the homogenization requirements of ultra-high pressure fluids, the manufacturing accuracy of the two semi-cylindrical valve bodies and the assembly accuracy of the mutual cooperation are relatively high, which is also an important reason why the cost of the existing Y-type homogenizing valve remains high. In addition, it is precisely because of the limitations of dimensional accuracy and assembly accuracy in the valve body manufacturing process that this type of Y-type homogenizing valve can currently meet the homogenization of graphene slurry at a fluid pressure of about 200MPA. According to the market price known to the applicant, the price of the existing Y-type homogenizing valve that can meet the use of 200MPA fluids is generally between tens of thousands and more than 100,000 yuan. And the Y-type homogenizing valve is a wearing part, and its effective use time is generally within 2000 hours. The higher the fluid working pressure, the shorter its effective use time.

[0003] To this end, in order to meet the process requirements of more than 250MPA proposed by the development of the industry, the industry urgently needs to develop a homogenizing valve that can meet the fluid pressure requirements of 250MPA or even more than 250MPA, and compared with the existing Y-type homogenizing valve, its price can be relatively lower, which is conducive to industrial promotion. Utility Model Content

[0004] The utility model aims to solve one of the technical problems in the related art at least to a certain extent: to provide a graphene slurry homogenizing device, which can make the fluid collide with a pressure of not less than 250MPA and has a low manufacturing cost.

[0005] To this end, one object of the utility model is to provide a graphene slurry homogenizing device, characterized in that it includes:

[0006] A distributor, having a feed interface and at least two discharge interfaces, for distributing the slurry to be homogenized from the feed interface to each discharge interface;

[0007] A homogenizing valve is composed of at least a valve body and a plurality of jet generators, wherein the valve body has an interactive cavity inside, each jet generator is arranged around the interactive cavity and is fixedly connected to the valve body in a detachable manner, the tail end of each jet generator is communicated with a corresponding discharge interface, the front end is arranged to face the interactive cavity and allow the ejected slurry jets to converge in the interactive cavity, the valve body has an injection channel for the slurry jets ejected from the front end of the jet generator to pass through, and an injection channel communicated with the interactive cavity for discharging the slurry in the interactive cavity;

[0008] The heat exchanger is arranged on the slurry pipeline connected to the injection channel and is used to cool the slurry flowing out of the injection channel.

[0009] The above technical scheme has the following advantages or beneficial effects: first, an interactive cavity, an outflow channel and an injection channel are formed on the valve body by machining, and then each independent jet generator is installed on the valve body, and the direction of each jet generator is kept consistent with the corresponding injection channel. At this time, the high-speed jets ejected by each jet generator can be injected into the interactive cavity through their respective injection channels and complete the homogenization of the slurry after the mutual collision in the interactive cavity. In this scheme, the processing cost of the valve body is low, and the structure of the jet generator is simple. The manufacturing cost of the homogenizing valve made by assembling the two is much lower than that of the homogenizing valve in the prior art. Secondly, for the homogenizing valve with this newly designed structure, in combination with a distributor and a heat exchanger, the graphene slurry homogenizing equipment can meet the process requirements of graphene homogenization treatment exceeding 250MPA. At the same time, the structures of the various components in the homogenizing equipment are simple, and the overall equipment cost is significantly lower than the homogenizing system composed of the existing Y-type homogenizing valve.

[0010] Preferably, there are two jet generators, both of which are provided with water outlets, and the center lines of the two water outlets intersect in the mutual cavity. The overall homogenizing valve formed by installing two jet generators on the valve body has a simple structure, and only needs to allow the high-speed jets ejected by the two jet generators to enter the mutual cavity through the injection channel to collide with each other, thereby achieving the homogenizing effect of the existing Y-type homogenizing valve. At the same time, its valve body can be obtained by drilling holes on a machine tool, and the jet generator has a simple structure, so the cost of the homogenizing valve formed by assembling the two is much lower than that of the existing Y-type homogenizing valve.

[0011] Preferably, there are three or more jet generators, each of which is provided with a water outlet, and the interactive cavity has a virtual theoretical collision point O, the center lines of the water outlets of the jet generators intersect at the theoretical collision point O, and all the jet generators are located above the horizontal plane where the theoretical collision point O is located.

[0012] Preferably, each jet generator is evenly distributed along the circumference of the vertical axis Z where the theoretical collision point O is located. The circumferential arrangement of multiple jet generators can not only greatly improve the output of slurry homogenization, but also the arrangement method of even distribution along the circumference makes the adjacent sides of any two adjacent high-speed jets collide with each other, so that the impact forces of the high-speed jets in all directions collide more fully, reducing the waste of impact force, so it has a better homogenization effect than the collision of two jet generators.

[0013] Preferably, the jet generator includes a nozzle body, the rear end of the nozzle body has an inlet connected to the corresponding discharge interface on the distributor, the front end of the nozzle body is a water outlet end, and a jewel nozzle is provided on the water outlet end. 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.

[0014] Preferably, the distributor has a feed interface arranged vertically, and a plurality of discharge interfaces arranged circumferentially around the center line of the feed interface, the number of the discharge interfaces 2 is the same as the number of the jet generators 5, and each discharge interface is connected to the corresponding jet generator.

[0015] Preferably, there are three jet generators, and the distributor is a four-way distributor, and the four-way distributor includes a feed interface and three discharge interfaces. The feed interface is arranged vertically, and the three discharge interfaces are evenly arranged circumferentially along the center line of the feed interface.

[0016] Preferably, the center line of any discharge interface on the distributor is parallel to the center line of the corresponding jet generator, and the center line of the discharge interface, the center line of the corresponding jet generator and the center line of the feed interface are all located in the same vertical plane.

[0017] Preferably, the heat exchanger includes a heat exchange chamber and a heat exchange tube, wherein the heat exchange chamber contains a heat-conducting medium, the middle portion of the heat exchange tube is placed in the heat exchange chamber, and one end of the heat exchange tube is connected to the ejection channel. The heat exchanger can rapidly cool down the graphene slurry after collision and refinement in the interactive chamber, and the temperature change is an important factor affecting the preparation of graphene powders. Therefore, after the cooling treatment, a graphene powder with better performance can be finally obtained.

[0018] 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

[0032] 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.

[0033] The graphene slurry homogenizing device according to an embodiment of the utility model is described in detail below with reference to the accompanying drawings.

[0034] 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.

[0035] 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.

[0036] by Figure 1 Based on the existing Y-type homogenizing valve shown in , based on the consideration of meeting the process requirements of graphene slurry with a higher fluid pressure and reducing processing costs, the utility model provides a graphene slurry homogenizing device, such as Figure 2-10 As shown, it includes a distributor 100 , a homogenizing valve 300 and a heat exchanger 400 .

[0037] The distributor 100 has a feed interface 1 and at least two discharge interfaces 2, each of which is connected to the feed interface 1 to form a multi-channel structure, so that the distributor 100 can be used to divide the slurry to be homogenized from the feed interface 1 to each of the discharge interfaces 2;

[0038] The homogenizing valve 300 includes a valve body 3 and a plurality of jet generators 5. The valve body 3 has an interactive cavity 4 inside. Each jet generator 5 is arranged around the interactive cavity 4 and is fixedly connected to the valve body 3 in a detachable manner. The tail end of each jet generator 5 is communicated with the corresponding discharge interface 2, and the front end is arranged to face the interactive cavity 4 so that the ejected slurry jets converge in the interactive cavity 4. The valve body 3 has an injection channel 6 for the slurry jets ejected from the front end of the jet generator 5 to pass through, and an injection channel 7 communicated with the interactive cavity 4 for discharging the slurry in the interactive cavity 4.

[0039] The heat exchanger 400 is arranged on the slurry pipeline connected to the injection channel 7 and is used to cool the slurry flowing out of the injection channel 7.

[0040] Specifically, Figure 4Take the case where two jet generators 5 are provided on the valve body 3 as an example. There are two jet generators 5, and both jet generators 5 are provided with water outlets. The valve body 3 has two mounting grooves 8 matching the jet generators 5. The front ends of the two jet generators 5 are respectively inserted into the corresponding mounting grooves 8 and the direction of the water outlets on the front ends of the jet generators 5 is aligned with the injection channel 6. At this time, the center lines of the two water outlets intersect in the interactive cavity 4, so that the high-speed jets generated by the jet generators 5 can be injected into the interactive cavity 4 through the corresponding injection channel 6. Finally, the two high-speed jets collide with each other in the interactive cavity 4 to achieve a homogenization effect. In this embodiment, the valve body 3 and the injection channel 6, the outflow channel 7, the interactive cavity 4 and the mounting groove 8 in the valve body 3 can be machined. For this purpose, after a limited number of calculations and experiments, the high-speed jets injected by the two jet generators 5 installed on the mounting grooves 8 can collide with each other in the interactive cavity 4, and finally achieve a homogenization effect.

[0041] like Figure 4 As shown, the jet generator 5 in this embodiment refers to a device that can pressurize a fluid, and the pressurized fluid can be ejected from a small hole in a straight line. Specifically, the jet generator 5 includes a nozzle body 5.1, the rear end of the nozzle body 5.1 is connected to the feed hydraulic pump through a liquid supply pipe, the front end of the nozzle body 5.1 is a water outlet, and a gem nozzle 5.2 is provided on the water outlet. The gem nozzle 5.2 has a liquid outlet hole 5.3 connected to the nozzle body 5.1, and the aperture of the liquid outlet hole 5.3 is much smaller than the inner diameter of the nozzle body 5.1, so that the fluid ejected from the liquid outlet hole 5.3 will form a high-speed jet ejected forward along the axis direction of the nozzle body 5.1. The directions of the two jet generators 5 are adjusted so that the high-speed jets generated by the two jet generators 5 meet in the interactive cavity 4 and collide with each other.

[0042] Based on the understanding of the above basic embodiments, Figures 4 to 6 As shown, the high-speed jets generated by the two jet generators 5 can basically achieve the homogenization effect after the fluids collide with each other as long as there is a mutual collision in the interactive cavity 4. The intersection point where the two high-speed jets collide with each other in the interactive cavity 4 is used as the theoretical collision point O, and a plane S1 is constructed with the axes of the two high-speed jets. In the plane S1, the two high-speed jets can use the theoretical collision point O as the starting point of the coordinate circle center and use the flow direction of the high-speed jet as the movement direction to construct a vector. Figures 4 to 6The vector is a plane vector, and the angle α between the plane vectors of the two high-speed jets at the theoretical collision point O is 0°~180°, and theoretically, the smaller the angle α is, the smaller the force component of the two vectors in the horizontal direction is, so the effect of the collision is worse, and vice versa, the larger the angle α is, the larger the force component of the two vectors in the horizontal direction is, so the effect of the collision is better. However, if the angle α is 180°, the force of the two vectors in the vertical direction downward is zero, which is not conducive to the discharge of the fluid after the collision, that is, the fluid after the first collision will agglomerate in the area where the theoretical collision point O is located. This agglomeration phenomenon will affect the continuous collision of the high-speed jets. For this reason, the angle α that should be reasonably considered in this embodiment is 60°~180°. In this embodiment, the angle α is also the angle α between the two center lines after the center lines of the water outlet ends of the two jet generators 5 intersect at the theoretical collision point O. The center line should not be understood as an infinitely extended straight line, but a line segment from the water outlet end to the theoretical collision point O.

[0043] Preferably, the angle α is any value of 60°, 70°, 80°, 90°, 100°, 110°, 120°, 130°, 140°, 150°, 160°, 170°, and 180°.

[0044] Table 1 below shows the particle size comparison test of two high-speed jets with angles α of 90° and 120° respectively:

[0045] Table 1:

[0046]

[0047] Note: The fluid selected in Table 1 is a slurry containing graphite particles, and the working pressure is 250 MPA.

[0048] From the comparison results in Table 1 above, it can be seen that in the first treatment and the second treatment, the angle α of 90° can reduce the particle size of the solid particles in the slurry faster than the angle α of 120°, but as the number of treatments increases, the slurry particle size treated with the angle α of 120° is significantly better than the solution with the angle α of 90°. Therefore, in this embodiment, when the fluid is a slurry containing graphite particles and the fluid pressure is 250MPA, the angle α is preferably 120°.

[0049] like Figure 6As shown, in this embodiment, the angle α is 120°, at which time the vector force of the two high-speed jets in the horizontal direction makes the two high-speed jets have a collision force, which is beneficial to the homogenization of the fluid, and the vector force of the two high-speed jets in the vertical direction is jointly downward, thereby forming a common downward resultant force, under which the two high-speed jets can flow downward in the vertical direction after colliding with each other, which is beneficial for the fluid to quickly move away from the theoretical collision point O after the collision so as to facilitate the continuous collision of the fluid. For this reason, in this embodiment, the ejection channel 7 is preferably downward in the vertical direction.

[0050] In the actual production process, the efficiency of fluid homogenization is also an important consideration in industrial production. Therefore, when the above embodiment is applied to the actual production process, the larger the diameter of the high-speed jet, the higher the fluid homogenization output. That is, the larger the aperture of the liquid outlet hole 5.3 on the jet generator 5, the greater the fluid flow rate that can be ejected per unit time by the liquid outlet hole 5.3 under the same pressure. Figure 5 The enlarged schematic diagram of the longitudinal section of the two high-speed jets along the plane S1 shown in the figure shows that when the angle α between the two high-speed jets is any value greater than or equal to 60° and less than 180°, the two high-speed jets preferentially collide with the adjacent inner area M1, while the impact force of the two high-speed jets colliding with each other in the outer areas M2 opposite to each other is much smaller than the impact force of the inner area M1. Therefore, the larger the diameter of the high-speed jet, the smaller the impact effect of the outer area M2 of the high-speed jet, and the poorer the homogenization effect. On the contrary, the smaller the diameter of the high-speed jet, the better the impact effect of the outer area M2 of the high-speed jet, and the better the homogenization effect. However, a high-speed jet with too small a diameter will directly affect the yield of fluid homogenization. Obviously, what this embodiment needs to consider is how to increase the yield without reducing the homogenization effect. To this end, the improvement of this embodiment is: Figure 8 and Fig. 9 As shown, a vertical axis Z is constructed with the preset theoretical collision point O in the interactive cavity 4 as the center of the circle, and at least three jet generators 5 are evenly distributed along the circumference of the vertical axis Z. Each jet generator 5 is provided with a water outlet, and the center lines of the water outlets of each jet generator 5 intersect at the theoretical collision point O, so that the central axis of the high-speed jets injected into the interactive cavity 4 by each jet generator 5 intersects at the theoretical collision point O. With the theoretical collision point O as the center of the circle, at least three high-speed jets oriented toward the theoretical collision point O are evenly distributed around the vertical axis Z in the circumference. In this embodiment, there are three high-speed jets, and there is an inner area M1 between any one of the three high-speed jets and the two adjacent high-speed jets where they collide with each other. At this time, any high-speed jet has two inner areas M1 at the same time on its cross section, so compared with the embodiment shown in FIG. Figure 7Compared with the embodiment in which there are only two high-speed jets, there are more inner areas M1, so that the collision effect of the fluid is better. On the other hand, compared with the embodiment in which there are two jet generators 5, three or more jet generators 5 split the slurry of the same flow rate into more points for collision, and the homogenization effect is better, which reduces the number of repeated collisions when producing small-particle products and speeds up production efficiency. Preferably, the jet generators 5 in this embodiment are four, five or six, and the multiple jet generators 5 are uniformly distributed along the circumference of the vertical axis Z. Preferably, the angle β between the central axis of the high-speed jet generated by any one of the jet generators 5 in this embodiment and the vertical axis Z is 30°~90°, and specifically the angle β is 30°, 40°, 50°, 60°, 70°, 80°, 89°, 90°.

[0051] Furthermore, all the jet generators 5 are located above the horizontal plane where the theoretical collision point O is located.

[0052] As a preferred embodiment of the above, Fig.10 As shown, a vertical axis Z and a horizontal plane S perpendicular to the vertical axis Z are constructed with the preset theoretical collision point O in the interactive cavity 4 as the center of the circle, and all the jet generators 5 are divided into a first jet generator 5 located above the horizontal plane S and a second jet generator 5 located below the horizontal plane S along the horizontal plane S, wherein the first jet generators 5 are two or more, and each first jet generator 5 is evenly distributed along the circumference of the vertical axis Z, and the second jet generator 5 is one or more, and the above-mentioned first jet generators 5 and second jet generators 5 are all facing the interactive cavity 4, and the central axis of the high-speed jet injected into the interactive cavity 4 by each jet generator 5 intersects at the theoretical collision point O. As a result, the high-speed jet generated by any second jet generator 5 collides with the high-speed jet generated by the adjacent first jet generator 5 at a position close to the theoretical collision point O. In this embodiment, the space in the vertical direction of the valve body 3 is fully utilized, so that the number of jet generators 5 can be further increased, thereby improving the fluid production.

[0053] 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.

[0054] The high-speed jet in the above embodiments refers to a columnar jet formed by ejecting a fluid from a small hole at a pressure exceeding 100 MPA. Taking the graphene field as an example, the diameter of the high-speed jet is generally 0.1~0.4mm, and the flow rate is generally greater than 100m / s.

[0055] As a preferred example of this embodiment: the distributor 100 is a four-way connector, which includes a feed interface 1 and three discharge interfaces 2. The feed interface 1 is arranged vertically, and the three discharge interfaces 2 are evenly arranged along the circumference of the center line of the feed interface 1. Specifically, the three discharge interfaces 2 correspond to the three jet generators 5 on the homogenizing valve one by one, and any one of the discharge interfaces 2 is connected to the interface at the tail end of the corresponding jet generator 5 through the respective pre-valve connecting pipes 200.

[0056] Preferably, the pre-valve connecting pipe 200 is made of a hard pipe, such as a stainless steel pipe. In order to reduce the deformation of the pre-valve connecting pipe 200 during the connection between the two ends of the pre-valve connecting pipe 200 and the discharge interface 2 and the tail end interface of the jet generator 5, and the influence of the deformation on the sealing of the interface, the further improvement of this embodiment is that: the discharge interface 2 is set so that the center line of the discharge interface 2 is parallel to the center line of the corresponding jet generator 5, and the center line of the discharge interface 2, the center line of the corresponding jet generator 5 and the center line of the feed interface 1 are located in the same vertical plane, so that the two ends of the pre-valve connecting pipe 200 form a connecting section that matches the discharge interface 2 and the tail end interface of the jet generator 5, and the connecting sections at the two ends of the pre-valve connecting pipe 200 are parallel to each other. In this embodiment, since the connecting sections at both ends of the pre-valve connecting pipe 200 remain parallel, and the discharge interface 2 and the tail end interface of the jet generator 5 are also parallel to each other, the connecting sections at both ends of the pre-valve connecting pipe 200 can be synchronously inserted into the discharge interface 2 and the tail end interface of the jet generator 5 in the same direction, making the installation process of the pre-valve connecting pipe 200 simple.

[0057] As a preferred example of this embodiment: the heat exchanger 400 includes a heat exchange chamber 9 and a heat exchange tube 10, wherein the heat exchange chamber 9 contains a heat transfer medium, the middle portion of the heat exchange tube 10 is placed in the heat exchange chamber 9, and one end of the heat exchange tube 10 is connected to the ejection channel 7, and the other end is exposed outside the heat exchange chamber 9. Specifically, the heat transfer medium may be water, or various existing heat transfer fluids, and the outer side wall of the heat exchange chamber 9 is provided with a refrigerant inlet and a refrigerant outlet connected to the heat exchange chamber 9.

Ordinary technicians in the field can change, modify, replace and modify the above embodiments within the scope of the present invention.

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.
