DETAILED DESCRIPTION

[0025] The embodiments of the present application are described in detail below, examples of which are shown in the accompanying drawings. The embodiments described below by referring to the accompanying drawings are exemplary and are intended to explain the present application, and cannot be understood as a limitation of the present application.

[0026] As Figures 1-8 shown, the fuel proportioning mixing device of the embodiment of the present application comprises a tank body 1 and a premixing channel 2.

[0027] The tank body 1 has a cavity, and in the height direction of the tank body 1, the cavity is divided into a first mixing cavity 11 and a second mixing cavity 12. The premixing channel 2 is connected with the tank body 1 and is placed in the cavity, the first mixing cavity 11 is located above the premixing channel 2, and the second mixing cavity 12 is located below the premixing channel 2. When the materials enter the second mixing cavity 12 from the first mixing cavity 11, the materials are premixed in the premixing channel 2.

[0028] Specifically, as Figure 1 and Figure 2 shown, the tank body 1 is internally provided with a premixing channel 2 for premixing of materials, the region of the tank body 1 above the premixing channel 2 is the first mixing cavity 11, and the region of the tank body 1 below the premixing channel 2 is the second mixing cavity 12. After a plurality of materials enter the first mixing cavity 11, the materials will converge and mix in the premixing channel 2 inside the tank body 1 during the process of entering the second mixing cavity 12 from the first mixing cavity 11 through the preset path, i.e. the premixing channel 2, so as to ensure that the materials can be fully contacted and premixed before entering the second mixing cavity 12, thereby improving the mixing effect and efficiency.

[0029] In the process of the fuel proportioning and mixing device of this embodiment of the invention, the material accumulated in the first mixing chamber 11 rushes into the premixing channel 2 at a high speed and pressure as it enters the second mixing chamber 12 from the first mixing chamber 11. When multiple materials are mixed, the high-speed and turbulent flow allows different materials to come into more full contact, collide and mix, reducing mixing dead zones, greatly improving the uniformity and efficiency of mixing, and enhancing the mixing effect.

[0030] In some embodiments, the premixing channel 2 includes a first guide member 21 and a second guide member 22 in sequence. The outer peripheral wall of the first guide member 21 is connected to the inner peripheral wall of the tank 1, and the minimum inner diameter of the first guide member 21 is greater than the maximum inner diameter of the second guide member 22.

[0031] Specifically, such as Figures 1-4 As shown, both the first guide member 21 and the second guide member 22 are inverted conical cylindrical structures, with the bottom end of the first guide member 21 connected to the top end of the second guide member 22. The bottom diameters of both the first guide member 21 and the second guide member 22 are the smallest, while the minimum diameter of the first guide member 21 is the maximum diameter of the second guide member 22. The interconnection between the bottom end of the first guide member 21 and the top end of the second guide member 22 ensures smooth fluid flow between them.

[0032] Understandably, both the first guide element 21 and the second guide element 22 adopt an inverted conical cylindrical structure design, which makes the premixing channel 2 have a shape that is wider at the top and narrower at the bottom. The structural characteristics of the inverted conical tube enable it to promote the rapid mixing of materials. Whether it is powder or liquid material, when two different materials flow through the premixing channel 2 at the same time, the fluid velocity increases as the pipe diameter gradually decreases.

[0033] The rapid flow of liquid materials generates a stronger impact force, effectively impacting and breaking up powders, significantly increasing the contact area between the powder and liquid. Simultaneously, a unique flow field is created within the inverted conical tube, inducing turbulence. In this turbulent state, the powder and liquid materials interweave and mix, effectively preventing powder agglomeration and achieving more uniform mixing. For mixing multiple liquid materials, the inverted conical tube can also accelerate the flow rate and create turbulence, promoting mixing and improving the overall mixing effect.

[0034] Meanwhile, the diameter difference between the first guide member 21 and the second guide member 22 significantly increases the flow velocity as the fluid flows from the larger-diameter conical section to the smaller-diameter conical section. Within the first guide member 21, the larger space allows for initial mixing and buffering of the fluid, enabling preliminary contact and diffusion between different components. Upon entering the smaller-diameter section of the second guide member 22, the high-speed fluid flow generates stronger shear forces and turbulence. This high-speed turbulence effectively disperses the powder within the liquid material, greatly promoting their fusion, improving mixing uniformity and efficiency, and resulting in a more uniform component distribution and more stable quality in the final product.

[0035] In some embodiments, the first guide member 21 is connected to the first mixing chamber 11, and the second guide member 22 is connected to the second mixing chamber 12.

[0036] like Figure 1 and Figure 2 As shown, the top end of the first guide member 21 is fixedly connected to the inner wall of the tank 1, and the top end of the second guide member 22 is fixedly connected to the bottom end of the first guide member 21. The top end of the first guide member 21 is connected to the top of the first mixing chamber 11, so that the material can directly enter the first guide member 21 from the first mixing chamber 11, and be guided by the first guide member 21 into the second guide member 22, and finally enter the second mixing chamber 12 through the second guide member 22, so that the material can enter the second mixing chamber 12 from the first mixing chamber 11.

[0037] In some embodiments, the premixed channel 2 further includes a spiral member 23, which is disposed inside the second guide member 22.

[0038] like Figure 5 As shown, the spiral component 23 is a spiral plate structure, that is, the spiral component 23 is located inside the second guide component 22, providing a flow path for the material flow, and the spiral component 23 can also increase the length of the flow path within a limited range, further improving the flow speed of the material when it falls, and improving the mixing uniformity and mixing efficiency of the material.

[0039] It is understandable that when the material passes through the premixing channel 2, it comes into contact with the surface of the spiral component 23, thereby changing the flow path and state of the fluid, prolonging the residence time of the material in the pipe, and improving the effect of mutual contact and mixing between various materials. At the same time, the spiral component 23 will further intensify the turbulence of the fluid, making the mixing between materials more intense, increasing the friction and shear force inside the fluid, thereby dispersing the material more effectively and improving the fusion effect.

[0040] In some embodiments, the fuel proportioning and mixing device of the present invention further includes a stirring assembly, which includes a rotating rod 13 and a stirring blade 14. The rotating rod 13 is connected to the tank 1 and located in the cavity. The extending direction of the rotating rod 13 is consistent with the extending direction of the tank 1, and the rotating rod 13 is rotatable relative to the tank 1. The stirring blade 14 is fitted onto the rotating rod 13. There are multiple stirring blades 14. At least one stirring blade 14 is provided in both the first mixing chamber 11 and the second mixing chamber 12.

[0041] Specifically, such as Figures 1-6 As shown, the rotating rod 13 is located at the center of the tank 1, and the axis of the rotating rod 13 coincides with the axis of the tank 1. The rotating rod 13 can be driven by an electric drive device (such as a motor) located outside the tank 1 to ensure the stable rotation of the rotating rod 13. The stirring blades 14 are mounted on the rotating rod 13, and according to the actual working conditions (such as the size of each chamber and the mixing space), different numbers of stirring blades 14 can be arranged in the first mixing chamber 11 and the second mixing chamber 12 respectively to ensure the mixing effect in each chamber.

[0042] like Figures 1-6 As shown, the top of the tank 1 is provided with a feed inlet. Various materials enter the first mixing chamber 11 of the tank 1 through the feed inlet and enter the second mixing chamber 12 through the premixing channel 2. The materials are initially mixed in the premixing channel 2. After the materials enter the second mixing chamber 12, the external electric drive device is started. The external electric drive device provides driving force to the rotating rod 13, so that the stirring blade 14 rotates in the tank 1 to further mix and stir the materials.

[0043] Since the premixing channel 2 is normally open, in order to ensure the mixing effect of the premixing channel 2, a large amount of material needs to be put into the tank 1 at the same time, so that a sufficient amount of material can enter the premixing channel 2 at the same time, so that the material can form turbulence when entering the premixing channel 2 and improve the mixing effect.

[0044] In some embodiments, the fuel proportioning and mixing device of the present invention further includes a blocking assembly, which includes a blocking part 3 and a guide part 4. The guide part 4 is fitted onto the rotating rod 13. The blocking part 3 is connected to the guide part 4. When the guide part 4 rotates in a first direction, the blocking part 3 abuts against the first guide member 21 to block the first guide member 21 and the second guide member 22. When the guide part 4 rotates in a second direction, the blocking part 3 moves toward a direction away from the first guide member 21 to conduct the first guide member 21 and the second guide member 22. The first direction is opposite to the rotation direction of the first direction.

[0045] like Figures 1-6As shown, the inner side of the first guide member 21 is also provided with a blocking part 3, and the outer side of the rotating rod 13 is sleeved with a guide part 4. The blocking part 3 is connected to the guide part 4. When the guide part 4 rotates in the first direction, the blocking part 3 abuts against the inner wall of the first guide member 21, so that the material is located in the first mixing chamber 11 (that is, the material gathers in the first mixing chamber 11 at this time). When the guide part 4 rotates in the second direction, the blocking part 3 moves away from the inner wall of the first guide member 21, and the material enters the second mixing chamber 12 from the first mixing chamber 11.

[0046] It is understandable that through the connection between the sealing part 3 and the guide part 4, and the connection and cooperation between the guide part 4 and the rotating rod 13, the rotating rod 13 can drive the guide part 4 to rotate. When the rotating rod 13 rotates in the first direction (the direction shown by the arrow in Figure 1), the guide part 4 is driven to rotate synchronously. At this time, the sealing part 3 abuts against the inner wall of the first guide member 21, that is, it seals the top of the first guide member 21. The connection between the first mixing chamber 11 and the first guide member 21 is blocked, and the premixing channel 2 is closed, so that the material entering the tank 1 is trapped in the first mixing chamber 11. At this time, the rotating rod 13 rotates and drives the stirring blade 14 to stir and mix the material. Due to the setting of the guide part 4, after the rotating rod 13 rotates in the first direction for a period of time, it needs to rotate in the second direction. The second direction is the opposite direction of the first direction. When the guide part 4 rotates in the second direction, the sealing part 3 is driven by the guide part 4 and moves away from the first guide member 21. At this time, the end of the first guide member 21 is connected to the first mixing chamber 11, and the premixing channel 2 is opened.

[0047] At the instant the premixing channel 2 opens, the material accumulated in the first mixing chamber 11 rushes into the premixing channel 2 with high speed and pressure. Inside the premixing channel 2, as the pipe diameter gradually decreases, the material flow velocity further accelerates, generating a strong turbulent effect. When mixing multiple materials, this high-speed and turbulent flow allows for more thorough contact, collision, and mixing between different materials, greatly improving the uniformity and efficiency of mixing and contributing to enhanced mixing results.

[0048] It should be noted that the cooperation between the sealing part 3 and the guiding part 4 can be achieved using a limiting structure. That is, the sealing part 3 and the guiding part 4 adopt the cooperation of a guide rail and a slider. In other words, when the rotating rod 13 rotates in the first direction, the sealing part 3 and the guide rail are relatively stationary; when the rotating rod 13 rotates in the second direction, the guide rail and the slider can move relative to each other, thereby moving the sealing part 3 away from the first guide member 21, so that the material in the first mixing chamber 11 flows to the second mixing chamber 12. Of course, the sealing part 3 and the guiding part 4 can also adopt other structural cooperation, such as the cooperation of a shaft and a groove.

[0049] In some embodiments, the blocking assembly further includes a limiting member 24, the first end of which is connected to the first guide member 21, and the second end of which penetrates the blocking portion 3. The blocking portion 3 is movable relative to the first guide member 21 along the extending direction of the limiting member 24.

[0050] like Figures 1-6 As shown, a limiting member 24 is fixedly provided on the inner side of the first guide member 21, and the sealing part 3 is connected to the limiting member 24. The limiting member 24 is a long rod-shaped member, and its bottom end is fixed on the inner wall of the first guide member 21. The sealing part 3 is provided with an opening corresponding to the limiting member 24, so that the sealing part 3 and the limiting member 24 are sleeved together. The arrangement of the limiting member 24 makes the sealing part 3 only able to move relative to the ground along the extension direction of the limiting member 24.

[0051] In some embodiments, the blocking assembly further includes a sleeve 31 and a fixing post 32. The sleeve 31 is connected to the blocking part 3 and is located at the end of the blocking part 3 away from the second guide member 22. The sleeve 31 is fitted onto the guide part 4. The first end of the fixing post 32 is connected to the sleeve 31, and the second end of the fixing post 32 is connected to the guide part 4.

[0052] like Figures 1-6 As shown, a sleeve 31 is fixedly connected to the top of the sealing part 3. Two sets of fixing posts 32 are fixedly provided inside the sleeve 31. The sealing part 3 is generally cone-shaped to prevent material from staying on the top of the sealing part 3. Through the insertion of the fixing posts 32 and the guide part 4, under the restriction of the limiting member 24, the rotation of the guide part 4 can move the fixing posts 32, thereby allowing the sealing part 3 to move up and down to control the opening and closing of the premixing channel 2.

[0053] It is understandable that the guide part 4 may be provided with a track or groove that cooperates with the fixed post 32, so that the fixed post 32 moves along the extension direction of the track or groove under the rotation of the guide part 4, thereby realizing the opening and closing function of the premixing channel 2.

[0054] In some embodiments, the sidewall of the guide portion 4 is provided with a first annular groove 41 and a spiral groove 42. The first annular groove 41 is located on the side of the guide portion 4 adjacent to the second guide member 22. The first end of the spiral groove 42 communicates with the first annular groove 41, and the second end of the spiral groove 42 extends in a direction away from the second guide member 22. The sealing assembly also includes a first guide plate 43, which is hinged to the guide portion 4, and at least a portion of the first guide plate 43 is placed in the first annular groove 41. The second end of the fixing post 32 is adapted to both the first annular groove 41 and the spiral groove 42. When the guide portion 4 rotates in a first direction, the fixing post 32 is located in the first annular groove 41 and moves circumferentially along the first annular groove 41, and the sealing portion 3 abuts against the interior of the first guide member 21. When the guide portion 4 rotates in a second direction, the fixing post 32 moves toward the spiral groove 42 via the first guide plate 43, so that the sealing portion 3 moves in a direction away from the second guide member 22.

[0055] like Figures 1-6 As shown, the guide part 4 is fixedly disposed on the outside of the rotating rod 13. The guide part 4 is a cylindrical component. The first annular groove 41 is an annular groove opened radially along the guide part 4. The spiral groove 42 is spirally opened radially along the guide part 4. The bottom end of the spiral groove 42 is connected to the top end of the first annular groove 41. A first guide plate 43 is provided in the first annular groove. The top end of the first guide plate 43 is located at the bottom end of the inner wall of one side of the spiral groove 42. The bottom end of the first guide plate 43 is attached to the bottom of the first annular groove 41. When the guide part 4 rotates in the second direction, the first guide plate 43 can guide the fixed post 32 into the spiral groove 42.

[0056] Initially, the fixed column 32 is located in the first annular groove 41. At this time, the bottom end of the sealing part 3 abuts against the inner wall of the first guide member 21, and the premixing channel 2 is closed. When the material enters the tank 1, it is blocked in the first mixing chamber 11. After all the material is added, the external electric drive device is started, and the rotating rod 13 rotates in the first direction. At the same time, the stirring blade 14 stirs and mixes the material. At this time, the guide part 4 is driven to rotate in the first direction, and the fixed column 32 moves in the first annular groove 41. After rotating for a period of time, in order to prevent the fixed column 32 from entering the spiral groove 42, it is necessary to control the rotating rod 13 to reverse, that is, the guide part 4 rotates in the second direction, so that the stirring blade 14 moves in different directions. The material is stirred and mixed by rotation. After mixing for a period of time, the guide part 4 is controlled to continue to rotate in the second direction, so that the fixed column 32 enters the spiral groove 42 under the guidance of the first guide plate 43. Due to the limiting member 24 limiting the sealing part 3, the movement of the fixed column 32 causes the sealing part 3 to rise. At this time, the premixing channel 2 is opened. When the fixed column 32 is at the top of the spiral groove 42, the sealing part 3 is fully opened, and the material enters the premixing channel 2 at high speed from the first mixing chamber 11. At this time, the external electric drive equipment can be turned off, so that the fixed column 32 is kept at the top of the spiral groove 42 and the sealing member is in the normally open state, and the material can completely enter the second mixing chamber 12.

[0057] Preferably, the inner wall of the sleeve 31 is attached to the outer wall of the guide part 4, thereby reducing the gap between the guide part 4 and the sleeve 31, so that only a small amount of material leaks from the spiral groove 42 into the premixing channel 2.

[0058] In some embodiments, the sidewall of the guide portion 4 is further provided with a second annular groove 44. In the extending direction of the guide portion 4, the second annular groove 44 is arranged opposite to the first annular groove 41, and the spiral groove 42 connects the first annular groove 41 and the second annular groove 44. The sealing assembly also includes a second guide plate 45, which is hinged to the guide portion 4, and at least a portion of the second guide plate 45 is placed in the second annular groove 44. When the guide portion 4 rotates in the second direction, the fixing post 32 moves into the second annular groove 44 via the spiral groove 42 and moves circumferentially along the second annular groove 44. When the guide portion 4 rotates in the first direction, the fixing post 32 moves toward the spiral groove 42 via the second guide plate 45, so that the sealing portion 3 moves toward the second guide member 22.

[0059] like Figures 1-6 As shown, a second annular groove 44 is provided at one end of the guide part 4 near the top. The second annular groove 44 is connected to the top end of the spiral groove 42. A second guide plate 45 is provided in the second annular groove 44. The fixing post 32 can enter the second annular groove 44 through the spiral groove 42. The second annular groove 44 is also opened radially along the guide part 4. The bottom end of the second annular groove 44 is connected to the top end of the spiral groove 42. The second guide plate 45 is located in the second annular groove 44. At the same time, the bottom end of the second guide plate 45 is located at the top end of the inner wall of one side of the spiral groove 42. The first guide plate 43 and the second guide plate 45 are respectively located on both sides of the inner wall of the spiral groove 42. The second guide plate 45 can guide the fixing post 32 into the second annular groove 44.

[0060] When the guide part 4 rotates in the second direction, the second guide plate 45 guides the fixed column 32 into the second annular groove 44. As the guide part 4 continues to rotate in the second direction, the fixed column 32 remains in the second annular groove 44, allowing the premixing channel 2 to have a certain opening time. When the fixed column 32 is on the back of the second guide plate 45, the guide part 4 is controlled to rotate in the first direction, causing the fixed column 32 to move towards the spiral groove 42. After the fixed column 32 enters the first annular groove 41 through the spiral groove 42, the sealing part 3 closes the premixing channel 2 again to prepare for the next mixing of materials.

[0061] Therefore, the material can be initially stirred by the stirring blades 14 before entering the premixing channel 2 for further mixing. At the same time, the impact force generated by the instantaneous entry of the material into the premixing channel 2 can further improve the mixing effect. By combining these two methods, the material can be fully and uniformly mixed, thus improving the mixing effect. In other embodiments, such asFigures 1-4 as well as Figure 7 and Figure 8 As shown, the guide section 4 has through slots 46 on both sides of the spiral groove 42. The ends of the first guide plate 43 and the second guide plate 45 are connected to a rotating shaft. The first guide plate 43 and the second guide plate 45 are rotatably connected in the through slots 46 through the rotating shaft. Both sets of through slots 46 are provided with positioning members 47. The positioning members 47 include cylinders 471 fixedly installed on both sides of the through slots 46. Elastic members 472 are fixedly installed in the cylinders 471. The two ends of the elastic members 472 are fixedly connected to the cylinders 471 and the rotating shafts of the two sets of guide plates, respectively. At the same time, both sets of through slots 46 are fixedly provided with fixing members 473. The fixing members 473 can abut against the back of the first guide plate 43 and the second guide plate 45, so that the first guide plate 43 can only rotate upward and the second guide plate 45 can only rotate downward.

[0062] In this embodiment, when the guide part 4 rotates in the first direction, the fixed column 32 can abut against the first guide plate 43 and rotate upward. After the fixed column 32 passes the first guide plate 43, the elastic element 472 can drive the first guide plate 43 to reset. Due to the rotational connection between the first guide plate 43 and the guide part 4, the rotating rod 13 can continuously rotate in the first direction. At the same time, the stirring blade 14 can stir the material. When it is necessary to open the sealing part 3 to further mix the material, the external electric drive device controls the rotating rod 13 to continuously rotate in the second direction. The guide part 4 is driven by the rotating rod 13 to rotate in the second direction. At this time, the first guide plate 43 and the second guide plate 43 are connected. Guided by the guide plate 45, the fixed column 32 enters the second annular groove 44 through the spiral groove 42. After entering the second annular groove 44, the guide part 4 rotates in the second direction, causing the fixed column 32 to abut against the second guide plate 45 and rotate downward. When the fixed column 32 passes the second guide plate 45, the elastic element 472 can drive the second guide plate 45 to reset, so that the rotating rod 13 can continue to rotate in the second direction, thereby keeping the sealing part in the normally open state, so that the material can fully pass through the premixing channel 2. When it is necessary to close the premixing channel 2, the guide part 4 is controlled to continue to rotate in the first direction, so that the fixed column 32 can re-enter the first annular groove 41 through the spiral groove 42.

[0063] Preferably, the elastic element 472 can be a disc spring. Due to the elasticity of the disc, after the shaft rotates, the disc spring can drive the first guide plate 43 and the second guide plate 45 to reset through the shaft.

[0064] Preferably, the first guide plate 43 and the second guide plate 45 can be arranged at an angle, such as... Figure 6 or Figure 8 As shown, this allows the first guide part 4 and the second guide part 4 to better guide the fixed column 32.
