Description

Technical Field

[0001] This invention relates to the technical field of homogenizers, specifically a variable speed homogenizer. Background Technology

[0002] Homogenizers are crucial production and processing equipment in fields such as pharmaceuticals, petrochemicals, food processing, and graphene. Taking graphene as an example, the basic working principle of existing homogenizers is to pressurize the graphene slurry to an ultra-high pressure state using a pressurization device. This pressure is used to achieve a higher slurry flow rate, causing the slurry to collide when injected into the homogenizer's interactive chamber, ultimately achieving a homogenization effect. However, with increasingly demanding product performance requirements, current graphene technology necessitates continuously increasing slurry pressure. For instance, current pressurization devices using piston pumps not only suffer from excessively high slurry pressures, affecting the reliability and safety of equipment operation but also significantly increasing equipment costs.

[0003] On the other hand, some technicians have considered improving the product performance of graphite slurry by increasing the number of homogenization cycles without increasing slurry pressure. However, it is clear that increasing the number of homogenization cycles significantly reduces production efficiency, which is detrimental to industrial production. Summary of the Invention

[0004] The present invention aims to at least partially solve one of the technical problems in the related art: to provide a variable speed homogenizer that can improve the homogenization effect of the fluid by changing the speed of the fluid while keeping the pressure of the input fluid constant.

[0005] Therefore, one object of the present invention is to provide a variable speed homogenizer, which includes a body, wherein a plurality of Tesla valves are provided in the body, any two adjacent Tesla valves are connected by a connecting pipe, and each Tesla valve and the connecting pipe are sequentially connected to form a flow channel for fluid to pass through. An inlet and an outlet are provided on the outer wall of the body, and the inlet and outlet are respectively connected to the two ends of the flow channel. The connecting pipe has at least one bend for changing the flow direction of the fluid in the connecting pipe.

[0006] The above technical solution has the following advantages or beneficial effects: First, when the fluid passes through the forward-mounted Tesla valve, it can be accelerated by the Tesla valve, thereby enabling the fluid to obtain a faster flow rate. Therefore, the fluid can obtain a better homogenization effect during the collision process. Second, when the fluid passes through the reverse-mounted Tesla valve, it can be decelerated by the Tesla valve. The cavitation effect generated during the fluid deceleration process can break up the solid particles in the fluid, ultimately improving the homogenization effect. Third, since the Tesla valve has no moving parts, the sealing performance of the entire flow channel is good, which is especially suitable for the homogenization of ultra-high pressure fluids. Finally, the high-speed flowing fluid collides with the inner wall of the pipe at the corner of the bend through the bend pipe, achieving a homogenization effect.

[0007] According to one embodiment of the present invention, a collision element is embedded at the corner of the bend, corresponding to the fluid flow direction. By adding the collision element, the high-speed fluid collides with the collision element during the reversal process within the bend, achieving a homogenization effect on the solid particles within the fluid. In this process, the collision between the fluid and the inner wall of the bend is reduced, thereby improving the service life of the bend.

[0008] According to one example of the invention, the Tesla valve includes a forward-mounted Tesla valve on the flow channel for accelerating the flow velocity of fluid within the flow channel. The forward Tesla valve accelerates the fluid within the flow channel, thereby achieving better homogenization when the fluid collides.

[0009] According to one example of the present invention, the plurality of Tesla valves include at least one forward Tesla valve mounted in the flow channel to accelerate the flow velocity of the fluid within the flow channel, and at least one reverse Tesla valve mounted in the flow channel to slow down the flow velocity of the fluid within the flow channel. When the fluid enters the flow channel from the inlet, it is accelerated by the forward Tesla valve, thereby achieving a faster flow velocity and resulting in better homogenization during subsequent collisions. When the fluid passes through the reverse Tesla valve, the reverse Tesla valve slows down the fluid. During the deceleration process, cavitation occurs, further breaking down solid particles contained in the fluid and ultimately improving the homogenization effect.

[0010] According to one embodiment of the present invention, the body has cooling pipes for reducing the temperature of all or part of the flow channel. The cooling pipes are arranged around the flow channel, and the outer wall of the body is provided with a coolant inlet and a coolant outlet communicating with both ends of the cooling pipes. The cooling pipes can cool the fluid in the flow channel, so that the fluid can always be maintained at an optimal operating temperature, especially for graphene slurry, where excessively high operating temperatures will have adverse effects on the morphology and flake size of the graphene.

[0011] Additional aspects and advantages of the invention will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of the invention. Attached Figure Description

[0019] Embodiments of the present invention are described in detail below, examples of which are illustrated in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.

[0020] The variable speed homogenizer according to an embodiment of the present invention will now be described in detail with reference to the accompanying drawings.

[0021] Example 1 The present invention provides a variable speed homogenizer, as shown in the figure, which includes a body 1. The body 1 is provided with a plurality of Tesla valves. Any two adjacent Tesla valves are connected by a connecting pipe 2. Each Tesla valve and the connecting pipe 2 are sequentially connected to form a flow channel for fluid to pass through. The outer wall of the body 1 is provided with an inlet 7 and an outlet 8, which are respectively connected to the two ends of the flow channel. The connecting pipe 2 has at least one bend 3 for changing the flow direction of the fluid in the connecting pipe 2.

[0022] In this embodiment, preferably, the Tesla valve and the body 1 are an integral structure. The body 1 contains a main pipe extending from the inlet 7 to the outlet 8, formed by subtractive processing. Multiple functional zones are sequentially arranged along this main pipe, and several arc-shaped branch pipes are machined within each functional zone. Both ends of each arc-shaped branch pipe are connected to the main pipe, thereby forming a Tesla valve within each functional zone. The portion of the main pipe between the Tesla valves serves as a connecting pipe 2, which is bent at at least once to form a bent pipe 3. The entire pipeline formed by all the Tesla valves and the connecting pipe 2 constitutes the flow channel in this embodiment. In this embodiment, the structure of the Tesla valve formed by the interconnection of the arc-shaped branch pipes and the main pipe is a conventional Tesla valve, which is common knowledge in the art; therefore, the structure of the Tesla valve is not described in detail in this embodiment.

[0023] Example 2 The bent tube 3 in the above embodiment includes an injection section, a bent section, and an injection section connected in sequence. When the fluid is injected from the injection section into the bent section, the fluid collides with the inner wall of the bent section and flows out from the injection section in a different direction than the injection section after the collision. During this process, the solid particles contained in the fluid are broken up by the collision with the inner wall of the tube, achieving a homogenization effect. Taking graphene slurry as an example, the graphite particles contained in the graphene slurry will continuously collide with the bent section of the bent tube 3. This local area will wear down rapidly after being constantly impacted by graphite particles, resulting in a short service life. Therefore, the improvement of this embodiment is that a collision body 4 is embedded at the corner of the bent tube 3 at the position corresponding to the fluid flow direction. Specifically, a collision body 4 is provided within the bent section of the bent pipe 3. This collision body 4 is embedded in the inner wall of the bent pipe 3, and its position corresponds to the flow direction of the fluid flowing from the injection section into the bent section. This causes the fluid flowing from the injection section into the bent section to collide with the collision body 4, then change direction, and finally exit from the ejection section. In this embodiment, the impact force of the fluid is concentrated on the collision body 4, greatly reducing impact wear on the inner wall of the bent pipe 3 itself and improving the service life of the bent pipe 3.

[0024] In this embodiment, the impactor 4 is made of a wear-resistant material. Preferably, the impactor 4 is made of diamond, or the impactor 4 is made of cubic boron nitride.

[0025] Furthermore, the inner wall of the flow channel within the body 1 has at least one protective layer, which is plated onto the inner wall of the flow channel, thereby reducing damage to the inner wall of the pipe during high-pressure, high-speed fluid flow. Preferably, the protective layer is a diamond coating.

[0026] Example 3 In existing technologies, to achieve better homogenization of graphene slurry and thus more effective graphite particle breakage, the slurry jet needs to reach higher speeds. This necessitates higher pressures to achieve faster flow rates. However, excessively high slurry pressures not only severely compromise the sealing and safety of the equipment but also significantly increase equipment costs. In particular, the solid graphite particles in the slurry cause a decrease in sealing performance with the piston pumps commonly used in the graphene industry. Piston pumps capable of providing pure water pumping pressures up to 600 MPa can only pressurize the slurry to around 100 MPa when pumping graphene slurry. Meanwhile, cutting-edge technologies in the graphene field typically require ultra-high pressures exceeding 250 MPa. Therefore, the demand for excessively high slurry pressures remains a significant challenge for the current graphene industry. Therefore, in the existing technology, when the pressure cannot meet the requirements, the only way to improve the quality of the final graphene slurry is to repeatedly homogenize the same slurry by increasing the number of homogenization cycles. However, this method greatly reduces homogenization efficiency, increases production costs, and is not conducive to industrialization.

[0027] Therefore, this embodiment proposes a method to further increase the fluid velocity without increasing the initial fluid pressure, which can also improve the homogenization effect during the homogenization process. Specifically, as follows: Figure 1 and Figure 2 As shown, the Tesla valve includes a forward Tesla valve 5 mounted in the flow channel to accelerate the flow velocity of fluid within the flow channel. The forward Tesla valve 5 refers to a Tesla valve connected in series in the flow channel, whereby the fluid flowing in from the inlet and passing through the forward Tesla valve 5 is accelerated by the forward Tesla valve 5.

[0028] As a preferred embodiment, the main body 1 contains two Tesla valves, both of which are forward Tesla valves 5. The two forward Tesla valves 5 are arranged sequentially at intervals along the flow direction of the flow channel. The two forward Tesla valves 5 are connected by a connecting pipe 2, which has two bends 3. The connecting pipe 2 formed by the two bends 3 is Z-shaped.

[0029] The homogenization process in this embodiment is as follows: Fluid enters the flow channel from the inlet 7 on the left end face of the main body 1. Upon passing through the first positive Tesla valve 5, the fluid is accelerated for the first time. At the location of the first bend 3, the fluid collides with the collision body 4 within the bend 3 due to the change in direction of the bend 3, causing the fluid to undergo its first breakage. The fluid, after its first breakage, continues into the second bend 3, and undergoes a second breakage during its change of direction. After these two breakages, the fluid is accelerated again by the second positive Tesla valve 5 and ejected from the outlet 8 on the right end face of the main body 1. At this point, the fluid's velocity after the two accelerations is greater than its initial velocity when flowing in from the inlet 7. During the ejection process from the outlet 8, the sudden expansion of the volume space causes instantaneous pressure relief, resulting in fluid atomization. Due to the cavitation effect, the fluid undergoes a third breakage. In this embodiment, the homogenization effect after these three breakages is significantly better than that of conventional T-type or Y-type homogenizing valves.

[0030] Example 4 Based on the improvement of Embodiment 3 above: the Tesla valve includes a forward Tesla valve 5 installed in the flow channel to accelerate the fluid flow velocity within the flow channel. This forward Tesla valve 5 refers to a Tesla valve connected in series in the flow channel, whereby the fluid flowing in from the inlet 7 and passing through the forward Tesla valve 5 is accelerated by the forward Tesla valve 5. For example... Figure 6 As shown, a bent connecting pipe 12 and an extension pipe 13 are provided between the discharge port 8 and the last positive Tesla valve 5. The discharge port 8, the extension pipe 13, the bent connecting pipe 12 and the last Tesla valve 5 are connected in sequence. The bent connecting pipe 12 has the same structure as the bent pipe 3.

[0031] Preferably, there are two Tesla valves in the body 1, both of which are forward Tesla valves 5. The two forward Tesla valves 5 are arranged sequentially at intervals along the flow direction of the flow channel, and the two forward Tesla valves 5 are connected by a connecting pipe 2, which has a bend 3.

[0032] The homogenization process in this embodiment is as follows: Fluid enters the flow channel from the inlet 7 on the right end face of the main body 1. Upon passing through the first positive Tesla valve 5, the fluid is accelerated for the first time. At the location of the first bend pipe 3, the fluid collides with the collision body 4 within the bend pipe 3 due to the change in direction of the bend pipe 3, causing the fluid to undergo its first breakage. Subsequently, the fluid, after the first breakage, is accelerated again by the second positive Tesla valve 5 and enters the bend connecting pipe 12. Since the bend connecting pipe 12 has the same structure as the bend pipe 3, the fluid undergoes a second breakage within the bend connecting pipe 12. Then, it is ejected from the outlet 8 on the left end face of the main body 1 through the extension pipe 13. At this point, the fluid's velocity after being accelerated twice is greater than its initial velocity when flowing in from the inlet 7. After being ejected from the outlet 8, the fluid experiences a sudden pressure release due to the sudden expansion of the volume space, causing the fluid to atomize. Due to the cavitation effect of the fluid, it undergoes a third breakage. In this embodiment, the homogenization effect of the fluid after these three breakages is significantly better than that of conventional T-type or Y-type homogenizing valves.

[0033] Example 5 In existing technologies, to achieve better homogenization of graphene slurry and thus more effective graphite particle breakage, the slurry jet needs to reach higher speeds. This necessitates higher pressures to achieve faster flow rates. However, excessively high slurry pressures not only severely compromise the sealing and safety of the equipment but also significantly increase equipment costs. In particular, the solid graphite particles in the slurry cause a decrease in sealing performance with the piston pumps commonly used in the graphene industry. Piston pumps capable of providing pure water pumping pressures up to 600 MPa can only pressurize the slurry to around 100 MPa when pumping graphene slurry. Meanwhile, cutting-edge technologies in the graphene field typically require ultra-high pressures exceeding 250 MPa. Therefore, the demand for excessively high slurry pressures remains a significant challenge for the current graphene industry. Therefore, in the existing technology, when the pressure cannot meet the requirements, the only way to improve the quality of the final graphene slurry is to repeatedly homogenize the same slurry by increasing the number of homogenization cycles. However, this method greatly reduces homogenization efficiency, increases production costs, and is not conducive to industrialization.

[0034] Furthermore, existing homogenization processes typically achieve better homogenization through increased fluid velocity, resulting in better homogenization during collisions. However, those skilled in the art often overlook the significant cavitation effect that occurs during the sudden deceleration of high-speed jets. This cavitation effect can also cause solid particles in the fluid to break up. Therefore, this embodiment breaks with conventional thinking and proposes a novel homogenization principle: utilizing the cavitation effect of high-speed fluid deceleration to achieve fluid homogenization. Specifically, as follows... Figures 3-6 As shown, the main body 1 is equipped with multiple Tesla valves. At least one of the Tesla valves is installed in the flow channel in a forward direction, and at least one of the Tesla valves is installed in the flow channel in a reverse direction. The Tesla valve installed in the flow channel in a forward direction is called a forward Tesla valve 5, and the Tesla valve installed in the flow channel in a reverse direction is called a reverse Tesla valve 6. The forward Tesla valve 5 refers to a Tesla valve connected in series in the flow channel in a forward direction, which accelerates the fluid flowing from the inlet and passing through the forward Tesla valve 5. The reverse Tesla valve 6 refers to a Tesla valve connected in series in the flow channel in a reverse direction, which decelerates the fluid flowing from the inlet and passing through the reverse Tesla valve 6. The forward Tesla valve 5 and the reverse Tesla valve 6 have the same structure but are installed in opposite directions. This allows the fluid to accelerate when passing through the forward Tesla valve 5 and decelerate when passing through the reverse Tesla valve 6 during its flow within the flow channel. The structure of the Tesla valve 5 is common knowledge in existing Tesla valves; therefore, the structure of the Tesla valve is not further described in this embodiment.

[0035] Furthermore, such as Figure 4 As shown, there are two Tesla valves in the main body 1, one is a forward Tesla valve 5 and the other is a reverse Tesla valve 6. The forward Tesla valve 5 and the reverse Tesla valve 6 are connected by a connecting pipe 2. The connecting pipe 2 has two bends 3, and the connecting pipe 2 formed by the two bends 3 is Z-shaped. The right end face of the main body 1 has a feed port 7 and the left end face has a discharge port. The direction of the flow of fluid in the flow channel is defined as the direction of the flow channel from the feed port 7 to the discharge port 8. The forward Tesla valve 5 is located upstream of the reverse Tesla valve 6 near the feed port 7.

[0036] The homogenization process in this embodiment is as follows: Fluid flows into the flow channel from the inlet 7 on the right end face of the main body 1. Upon passing through the forward Tesla valve 5, it is accelerated by the valve. The accelerated fluid then flows into the connecting pipe 2. Upon passing through the first bend 3, the fluid collides with the collision body 4 within the bend 3 due to the change in direction, causing the fluid to undergo its first breakage. The fluid then continues into the second bend 3, where a second breakage occurs. After these two breakages, the fluid is decelerated by the reverse Tesla valve 6. During this deceleration, cavitation occurs in the fluid, causing the solid particles within it to be broken a third time. Finally, the fluid, after three breakages, is ejected from the outlet 8 located on the left end face of the main body 1. In this embodiment, the homogenization effect after three breakages is significantly better than that of conventional T-type or Y-type homogenizing valves.

[0037] Example 6 Based on the improvements in Embodiment 5 above, the main body 1 is provided with multiple Tesla valves. At least one of the multiple Tesla valves is installed in the forward direction on the flow channel, and at least one of the multiple Tesla valves is installed in the reverse direction on the flow channel. The Tesla valve installed in the forward direction on the flow channel is a forward Tesla valve 5, and the Tesla valve installed in the reverse direction on the flow channel is a reverse Tesla valve 6. The forward Tesla valve 5 refers to a Tesla valve connected in series in the forward direction on the flow channel, whereby the fluid flowing in from the inlet 7 and passing through the forward Tesla valve 5 can be accelerated by the forward Tesla valve 5. Figure 5 As shown, a bent connecting pipe 12 and an extension pipe 13 are provided between the discharge port 8 and the last positive Tesla valve 5. The discharge port 8, the extension pipe 13, the bent connecting pipe 12 and the last Tesla valve 5 are connected in sequence. The bent connecting pipe 12 has the same structure as the bent pipe 3.

[0038] Preferably, there are two Tesla valves in the body 1, one of which is a forward Tesla valve 5 and the other is a reverse Tesla valve 6. The forward Tesla valve 5 and the reverse Tesla valve 6 are connected by a connecting pipe 2, which has a bend 3.

[0039] The homogenization process in this embodiment is as follows: Fluid enters the flow channel from the inlet 7 on the right end face of the main body 1. When passing through the forward Tesla valve 5, the fluid is accelerated. At the location of the bend pipe 3, the accelerated fluid collides with the collision body 4 inside the bend pipe 3 due to the change in direction of the bend pipe 3, causing the fluid to undergo its first breakage. Subsequently, the fluid, after its first breakage, is decelerated by the reverse Tesla valve 6. During this deceleration, cavitation occurs in the fluid, causing the solid particles within it to undergo a second breakage. The fluid after these two breakages enters the bend connecting pipe 12. Since the bend connecting pipe 12 has the same structure as the bend pipe 3, the fluid undergoes a third breakage within the bend connecting pipe 12. Finally, it is ejected from the outlet 8 on the left end face of the main body 1 through the extension pipe 13. In this embodiment, the homogenization effect of the fluid after these three breakages is significantly better than that of existing conventional T-type or Y-type homogenizing valves.

[0040] Example 7 Based on the improvements of Embodiment 5 above, such as Figure 3 As shown, there are two Tesla valves in the main body 1, one is a forward Tesla valve 5 and the other is a reverse Tesla valve 6. The forward Tesla valve 5 and the reverse Tesla valve 6 are connected by a connecting pipe 2. The connecting pipe 2 has two bends 3, and the connecting pipe 2 formed by the two bends 3 is Z-shaped. The right end face of the main body 1 has a feed port 7 and the left end face has a discharge port. The direction of the flow of fluid in the flow channel is defined as the direction of the flow channel from the feed port 7 to the discharge port 8. The reverse Tesla valve 6 is located upstream of the forward Tesla valve 5 near the feed port 7.

[0041] The homogenization process in this embodiment is as follows: Fluid flows into the flow channel from the inlet 7 on the right end face of the main body 1. It is decelerated by the reverse Tesla valve 6, causing cavitation. The solid particles within the fluid are broken up for the first time due to this deceleration. The broken fluid flows into the connecting pipe 2 and, upon passing through the first bend pipe 3, collides with the collision body 4 within it due to the change in direction, causing a second breakage. The fluid then continues into the second bend pipe 3, where a third breakage occurs. After these three breakages, the fluid is accelerated by the forward Tesla valve 5 and then ejected from the outlet 8 on the left end face of the main body 1. Upon ejection from the outlet 8 after being accelerated by the forward Tesla valve 5, the sudden expansion of the volume causes instantaneous pressure release, atomizing the fluid. At this point, due to the cavitation effect, the fluid undergoes a fourth breakage. In this embodiment, the homogenization effect of the fluid after four crushing processes is significantly better than that of existing conventional T-type or Y-type homogenizing valves.

[0042] Example 8 In the above embodiments, since the fluid homogenization process occurs within the body 1, the fluid converts some of its kinetic energy into internal energy, causing the fluid to heat up. Excessive temperature can negatively impact the homogenization effect, especially since the fluid is graphene slurry; excessively high temperatures can adversely affect the morphology and flake size of the graphene. Therefore, this embodiment improves upon this by including cooling pipes within the body 1 to reduce the temperature of all or part of the flow channel. These cooling pipes are arranged around the flow channel, and the outer wall of the body 1 has a coolant inlet 10 and a coolant outlet 11 connected to both ends of the cooling pipes. Preferably, the cooling pipes in this embodiment extend spirally along the length of the flow channel and around its circumference. The flow of coolant within the cooling pipes allows the heat of the fluid within the flow channel to be transferred to the coolant through thermal conduction within the body, ultimately achieving cooling.

[0043] Preferably, in this embodiment, a cooling zone 9 is provided within the body 1 at a position corresponding to the heat concentration area on the flow channel, and the middle portion of the cooling pipe is located within the cooling zone 9. Further, the pipe length per unit volume of the cooling pipe within the cooling zone 9 is greater than the pipe length per unit volume of the cooling pipe outside the cooling zone 9.

[0044] The fluid in the above embodiments should be understood as a medium that can flow in a channel, which can be a gas, liquid, gas-liquid mixture, liquid slurry containing solid particles, etc., especially the fluid is a graphene slurry containing solid graphene particles in the field of graphene.
