Description

Technical Field

[0001] The present invention relates to the technical field of injectors, and specifically to a self-rotating injector with adjustable injection angle. Background Art

[0002] Self-rotating injectors are widely used in processes such as liquid spraying and atomization. Their core working principle is to make the liquid generate a rotational movement through a rotating nozzle or spray head, thereby forming an atomized spray jet.

[0003] However, during actual use, the inventor found that when the injection angle increases, the direction of the spray from the nozzle changes, and the liquid flow rate may fluctuate due to factors such as gravity and air flow resistance. A larger injection angle may cause the liquid to be unable to move stably along the original path during spraying, thus affecting the stability of the flow rate. Moreover, with the change of the injection angle, the liquid sprayed by the nozzle may show uneven flow distribution in different directions, increasing the difficulty of controlling the coating thickness. Especially during large-area spraying, local accumulation or lack of coating may occur. In addition, for self-rotating injectors that need to mix multiple liquids, the prior art is difficult to ensure the proportion and mixing uniformity of different liquids during injection angle adjustment. Especially in adjustable-angle devices, changes in liquid flow rate and nozzle pressure will cause uneven mixing. Summary of the Invention

[0004] To solve the defects existing in the prior art, the present invention provides a self-rotating injector with adjustable injection angle.

[0005] To solve the above technical problems, the present invention provides the following technical solutions: The present invention provides a self-rotating injector with adjustable injection angle, comprising: A mixing tank, a flow splitting tank, and a plurality of nozzle assemblies provided on the flow splitting tank; The interior of the mixing tank is divided into a plurality of mixing chambers by at least one partition plate, and a stirring assembly for stirring raw materials is provided inside the mixing tank; A static mixing unit is provided at the upper end inside the flow splitting tank corresponding to the outlet of the mixing tank, and a flow disturbing assembly is provided at the lower end of the flow splitting tank; An air-driven assembly is further provided outside the flow splitting tank, and the air-driven assembly drives the static mixing unit to vibrate by driving the flow disturbing assembly to work; The air-driven assembly includes a first pneumatic component corresponding to the flow splitting tank, second pneumatic components provided at the upper and lower ends of the nozzle assembly, and a plurality of third pneumatic components provided outside the outlet of the nozzle assembly.

[0006] As a preferred technical solution of the present invention, two groups of partition plates are provided, and the two groups of partition plates divide the interior of the mixing tank into three mixing chambers. Each partition plate is obliquely arranged inside the mixing tank and is provided with a discharge port.

[0007] As a preferred technical solution of the present invention, the stirring assembly includes a driving unit fixedly arranged at the upper end of the mixing tank, a stirring rod transmission-connected to the driving unit, and a stirring blade arranged outside the stirring rod; The number of stirring blades arranged in the three mixing chambers increases sequentially from top to bottom.

[0008] As a preferred technical solution of the present invention, the static mixing unit includes a fixed plate fixedly arranged inside the diversion tank, an elastic plate connected to the fixed plate, and a barrier mesh plate fixedly arranged inside the elastic plate.

[0009] As a preferred technical solution of the present invention, the spoiler assembly includes a driving wheel arranged at the outer bottom of the diversion tank, a stirring unit arranged inside the diversion tank and transmission connected to the driving wheel, a guide turntable fixedly arranged at the upper end of the stirring unit, and several groups of levers arranged on the guide turntable.

[0010] As a preferred technical solution of the present invention, the upper end surface of the guide turntable is inclined and has a guide groove, and the lower end of the lever is clamped inside the guide groove and is slidably connected with a collar fixed inside the diversion tank; Driven by the guide turntable, a plurality of groups of the levers alternately impact the elastic plates in the static mixing unit and drive the barrier screen plates to vibrate.

[0011] As a preferred technical solution of the present invention, the first pneumatic parts are provided in two groups and the two groups of the first pneumatic parts are arranged opposite to each other. The first pneumatic parts include a first pneumatic unit with an air outlet facing the driving wheel and a second pneumatic unit with an air outlet extending into the interior of the diversion tank.

[0012] As a preferred technical solution of the present invention, the nozzle assembly includes a connecting piece fixedly connected to the diversion tank, a hose connected to the connecting piece, a spray head arranged at the other end of the hose, and a telescopic rod piece one end of which is hinged to the spray head and the other end of which is hinged to the connecting piece.

[0013] As a preferred technical solution of the present invention, two groups of second pneumatic parts are provided, and the two groups of second pneumatic parts are respectively fixedly arranged at the upper end and the lower end of the injection head. The air outlet of the second pneumatic part faces away from the injection head and the angle α between the air outlet and the central axis of the injection head is 30°-60°.

[0014] As a preferred technical solution of the present invention, several groups of the third pneumatic components are arranged in an array along the circumferential direction of the spray head.

[0015] The beneficial effects of the present invention are as follows: 1.

The several groups of third pneumatic components work together with the nozzle assembly, and can provide stable air flow pressure in multiple directions outside the outlet of the nozzle assembly. Especially when the spraying angle changes greatly, through the guiding action of the air flow, the liquid maintains a stable spraying direction and atomization effect during the spraying process, thereby improving the uniformity and consistency of the coating.

[0017] 3. In the present invention, by arranging the flow disturbing component in cooperation with the first pneumatic component, when the first pneumatic component works, it can drive the driving runner to rotate, and finally drive multiple groups of lever rods to alternately impact the elastic plate in the static mixing unit and drive the barrier mesh plate to vibrate. Such a setting can improve the flow disturbing effect of the static mixing unit on the raw materials, avoid the accumulation of raw materials on the static mixing unit, and ensure the flow efficiency of the raw materials inside the shunt tank. In addition, the air flow generated by the second pneumatic unit extending into the shunt tank can form tiny bubbles, further promoting the interaction within the liquid, helping to reduce the viscosity of the liquid and improve the mixing efficiency.

[0018] 4. In the present invention, by arranging a second pneumatic component on the nozzle assembly for controlling the angle adjustment of the nozzle assembly, it is convenient to realize the automatic angle adjustment work of the nozzle assembly.

Specific embodiments

[0028] The following is a description of the preferred embodiments of the present invention with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are only for the purpose of illustrating and explaining the present invention, and are not used to limit the present invention.

[0029] Such as Figures 1 - 3As shown in the figure, a spin-type injector with adjustable injection angle includes a mixing tank 1, a shunt tank 2, a nozzle assembly 3, a stirring assembly 4, a static mixing unit 5, a flow disturbance assembly 6, and a pneumatic driving assembly 7. The nozzle assembly 3 is arranged on the shunt tank 2. Inside the mixing tank 1, at least one set of partition plates 11 divides the interior of the mixing tank 1 into several sets of mixing chambers 12. Inside the mixing tank 1, a stirring assembly 4 for stirring raw materials is provided. At the upper end inside the shunt tank 2, corresponding to the outlet of the mixing tank 1, a static mixing unit 5 is arranged. At the lower end of the shunt tank 2, a flow disturbance assembly 6 is arranged. On the outside of the shunt tank 2, a pneumatic driving assembly 7 is also arranged. The pneumatic assembly drives the flow disturbance assembly 6 to work, thereby driving the static mixing unit 5 to vibrate. The pneumatic driving assembly 7 includes a first pneumatic component 71 arranged corresponding to the shunt tank 2, second pneumatic components 72 arranged at the upper and lower ends of the nozzle assembly 3, and several sets of third pneumatic components 73 arranged outside the outlet of the nozzle assembly 3.

[0030] Among them, by arranging a plurality of mixing chambers 12 inside the mixing tank 1, the mixing effect of the liquid is gradually enhanced, so that the liquid reaches an ideal uniform state before entering the injection system. After passing through the static mixing unit 5, the raw materials are fully mixed, providing a more stable liquid state for the subsequent injection or coating process.

[0031] The shunt tank 2 plays the role of collecting and distributing the mixture. The design of the shunt tank 2 is not only for storing materials, but also needs to optimize and accelerate the material flow through the cooperation of the static mixing unit 5 and the flow disturbance assembly 6. The static mixing unit 5 inside the shunt tank 2 is located at the upper end, corresponding to the outlet position of the mixing tank 1. Its function is to further enhance the mixing effect of the materials, ensuring that the mixed liquid or gas can reach a more uniform state before injection. The flow disturbance assembly 6 at the lower end is used to disrupt the flowing materials, making the flow of the materials more uniform and having better kinetic characteristics.

[0032] The flow disturbance assembly 6 is usually located at the lower end of the shunt tank 2 and is used to enhance the mixing effect by changing the flow direction of the fluid. By generating flow disturbances, the flow disturbance assembly 6 can increase the turbulence degree of the fluid, which helps to improve the mixing rate of substances inside the fluid, thereby optimizing the conveying efficiency of the materials.

[0033] The pneumatic driving assembly 7 is the power source of this system and controls a series of actions through air pressure. In this design, the pneumatic driving assembly 7 changes the flow state of the fluid by activating the flow disturbance assembly 6, thereby further enhancing the mixing effect. The pneumatic driving assembly 7 includes multiple pneumatic devices, which are respectively arranged at the upper and lower ends of the shunt tank 2, the nozzle assembly 3, and outside the outlet of the nozzle assembly 3. Through the coordinated action of the pneumatic system, the movement of each component can be precisely controlled, enabling the injection effect to be adjusted according to needs.

[0034] In summary, the self-spinning ejector in the present invention can effectively improve the mixing and ejection effects of materials through the combined action of multiple highly coordinated components.

[0035] During operation, the diversion tank 2 can generate rotation and drive the nozzle assembly 3 to rotate and spray. This is the prior art and the specific structure will not be described in detail.

[0036] Further, if Figure 2 As shown, the partition plates 11 are provided in two groups, and the two groups of partition plates 11 divide the interior of the mixing tank 1 into three mixing chambers 12. Each partition plate 11 is obliquely arranged inside the mixing tank 1 and is provided with a discharge port 111; The stirring assembly 4 includes a driving unit 41 fixedly arranged at the upper end of the mixing tank 1, a stirring rod 42 drivingly connected to the driving unit 41, and a stirring blade 43 arranged outside the stirring rod 42; The number of stirring blades 43 arranged in the three mixing chambers 12 increases sequentially from top to bottom.

[0037] The mixing tank 1 is designed to provide a mixing space for raw materials. The interior of the mixing tank 1 is divided into multiple mixing chambers 12 by multiple partitions 11. Each mixing chamber 12 can be controlled individually to ensure that different raw materials can be fully mixed at appropriate locations.

[0038] In detail, the inclination angle of the partition plate 11 helps the flow of fluid and the relative movement of materials, so that the materials can produce turbulence effect when flowing through different chambers, thereby accelerating the mixing of materials. The inclined partition plate 11 not only helps the flow of materials, but also can avoid dead corners and stagnation by guiding the materials to flow to the discharge port 111. Each partition plate 11 is provided with a discharge port 111, which ensures that the materials in the mixing chamber 12 can flow to the next mixing chamber 12 in sequence or simultaneously.

[0039] The mixing chamber 12 at the top is usually used for preliminary mixing of materials, with the purpose of making the materials of different components roughly evenly distributed before entering the next chamber. Therefore, the mixing chamber 12 has relatively few stirring blades 43, which are mainly used for preliminary mixing. The mixing effect of the materials in the middle mixing chamber 12 will be more delicate, further breaking up larger particles to form a more uniform mixture. As the difficulty of mixing the materials gradually increases, the number of stirring blades 43 is gradually increased to provide more hybrid power to ensure sufficient contact and reaction between the materials. The lower mixing chamber 12 is the final mixing stage, and it is necessary to ensure that the materials are mixed evenly, so the number of stirring blades 43 is the largest to provide a stronger stirring efficiency and ensure that the materials reach the best mixing state, which is suitable for subsequent injection or processing.

[0040] Further, if Figures 2 - 5 As shown, the static mixing unit 5 includes a fixed plate 51 fixedly arranged inside the diversion tank 2 , an elastic plate 52 connected to the fixed plate 51 , and a barrier mesh plate 53 fixedly arranged inside the elastic plate 52 .

[0041] Among them, when the material passes through the static mixing unit 5, it will be forced to change the flow direction or slow down the flow speed, thereby enhancing the mixing effect. The static mixing unit 5 is arranged at the upper end of the diversion tank 2. In this way, it is further ensured that the material at the outlet of the mixing tank 1 can be effectively fluidically mixed before entering the diversion tank 2, thereby reducing unevenness.

[0042] In detail, the static mixing unit 5 is a mixing device without moving parts. It guides the fluid movement through a fixed structure, changes the flow trajectory, and achieves efficient mixing. When the raw material passes through the barrier mesh plate 53, it can disperse the fluid flow, slow down the flow rate, and form local eddies or shear effects when the fluid passes through, thereby improving the mixing uniformity. The grid size, pore size distribution and material properties of the barrier mesh plate 53 will be optimized according to factors such as the viscosity and flow rate of the material.

[0043] Further, if Figures 3 - 4 As shown, the spoiler assembly 6 includes a driving wheel 61 disposed at the outer bottom of the diversion tank 2, a stirring unit 62 disposed inside the diversion tank 2 and drivingly connected to the driving wheel 61, a guide turntable 63 fixedly disposed on the upper end of the stirring unit 62, and a plurality of groups of levers 64 disposed on the guide turntable 63; The upper end surface of the guide turntable 63 is inclined and has a guide groove 631, and the lower end of the lever 64 is clamped inside the guide groove 631 and is slidably connected with a collar 65 fixed inside the diversion tank 2; Driven by the guide turntable 63 , the plurality of groups of the levers 64 alternately hit the elastic plate 52 in the static mixing unit 5 and drive the barrier screen 53 to vibrate.

[0044] Among them, by setting the spoiler component 6 to cooperate with the first pneumatic part 71, the first pneumatic part 71 can drive the driving wheel 61 to rotate when working, and finally drive multiple groups of levers 64 to alternately impact the elastic plate 52 in the static mixing unit 5 and drive the blocking mesh plate 53 to vibrate. This setting can improve the spoiler effect of the static mixing unit 5 on the raw material, avoid the accumulation of raw materials on the static mixing unit 5, and ensure the flow efficiency of the raw materials inside the diversion tank 2. In addition, the airflow generated by the second pneumatic unit 712 extending into the diversion tank 2 can form tiny bubbles, further promote the interaction within the liquid, help reduce the viscosity of the liquid and improve the mixing efficiency.

[0045] Specifically, when the first pneumatic component 71 operates, it can drive the driving runner 61 to rotate. The rotation of the driving runner 61 will synchronously drive the stirring unit 62 to rotate, and then drive the guiding turntable 63 to rotate. After the guiding turntable 63 rotates, multiple groups of dial rods 64 arranged at its upper end will move inside the guiding groove 631, and under the limiting effect of the collar 65, they will move up and down. During the up and down movement, on the one hand, the raw materials inside the shunt tank 2 are disturbed again, and on the other hand, it is mainly used to impact the elastic plate 52 in the static mixing unit 5 and drive the barrier mesh plate 53 to vibrate, so as to ensure that the raw materials fall smoothly and quickly from the barrier mesh plate 53.

[0046] It should be noted that since the raw materials are already sufficiently uniform after passing through the mixing tank 1 and the static mixing unit 5, the stirring unit 62 can be designed as stirring blades with less cutting effect on the raw materials.

[0047] Further, as Figure 3 shown, there are two sets of the first pneumatic components 71, and the two sets of the first pneumatic components 71 are arranged oppositely. The first pneumatic component 71 includes a first pneumatic unit 711 with an air outlet facing the driving runner 61 and a second pneumatic unit 712 with an air outlet extending into the shunt tank 2.

[0048] The first pneumatic unit 711: Its air outlet faces the driving runner 61. Its main function is to generate pneumatic force through the ejection of air flow, push the movement of the turbulence generating component 6, and optimize the stirring and fluid disturbance effects. The second pneumatic unit 712: Its air outlet extends into the shunt tank 2, directly affecting the flow of the fluid inside the shunt tank 2, further enhancing the stirring effect and optimizing the uniform mixing of the materials.

[0049] Further, as Figures 6 - 7 shown, the nozzle assembly 3 includes a connecting piece 31 fixedly connected to the shunt tank 2, a hose 32 connected to the connecting piece 31, a spray head 33 arranged at the other end of the hose 32, and a telescopic rod member 34 with one end hinged to the spray head 33 and the other end hinged to the connecting piece 31.

[0050] There are two sets of the second pneumatic components 72, and the two sets of the second pneumatic components 72 are respectively fixedly arranged at the upper and lower ends of the spray head 33. The air outlet of the second pneumatic component 72 faces away from the spray head 33, and the included angle with the central axis of the spray head 33 is α. Preferably, the angle of α is 30° - 60°. The second pneumatic component 72 controls the movement of the nozzle assembly 3, thereby adjusting the spraying angle to meet different usage requirements.

[0051] Among them, by providing a second pneumatic component 72 on the nozzle assembly 3 for controlling the angle adjustment of the nozzle assembly 3, it is convenient to realize the automatic angle adjustment of the nozzle assembly 3. At the same time, the present invention ensures the uniform spraying of raw materials and realizes the automatic adjustment of the nozzle angle by the coordinated operation of the first pneumatic component 71, the second pneumatic component 72 and the third pneumatic component 73, forming an efficient, complementary and coordinated working system.

[0052] Specifically, two groups of the second pneumatic components 72 are respectively arranged at the upper and lower ends of the spray head 33 to ensure that thrust can be applied in different directions, enabling multi-dimensional adjustment of the nozzle. When the second pneumatic component 72 works, compressed gas is ejected from the air outlet to form a reaction thrust, pushing the spray head 33 to deflect in the opposite direction. The upper and lower groups of pneumatic components can be controlled independently or jointly to provide balanced thrust in the up and down directions and maintain the stability of the spray head 33.

[0053] Furthermore, as Figure 8 shown, several groups of the third pneumatic components 73 are arranged in an array along the circumferential direction of the spray head 33. The third pneumatic components 73 are mainly used to adjust the spraying direction and spraying intensity to ensure that the material can be accurately sprayed.

[0054] Among them, through several groups of the third pneumatic components 73 outside the outlet of the nozzle assembly 3, several groups of the third pneumatic components 73 work together with the nozzle assembly 3, and can provide stable air flow pressure in multiple directions outside the outlet of the nozzle assembly 3. Especially when the spraying angle changes greatly, through the guiding action of the air flow, the liquid can maintain a stable spraying direction and atomization effect during spraying, thereby improving the uniformity and consistency of the coating. Through the array layout, the third pneumatic components 73 can provide air flow pressure from different directions respectively, not only adjusting the longitudinal spraying direction, but also being able to adjust the lateral spraying amplitude, increasing the adaptability and flexibility of the spray head 33.

[0055] Each group of the third pneumatic components 73 can adjust the air flow pressure according to requirements, thereby affecting the spraying intensity. When strong spraying is required, the pneumatic component outputs air flow with higher pressure to increase the spraying force; when gentle spraying is required, the air flow pressure is reduced to ensure that the sprayed liquid is uniform and delicate. The coordinated action of the third pneumatic components 73 ensures the stability of the air flow intensity, and even during high-intensity spraying or large-range spraying, the uniformity and consistency of the sprayed liquid can be maintained, avoiding unstable problems of liquid flow.

[0056] Raw material mixing stage: The raw materials enter through the mixing tank 1. The stirring assembly 4 drives the stirring rod 42 and the stirring blade 43 through the driving unit 41 to continuously mix the raw materials. As the raw materials are gradually stirred, the materials flow between the chambers and generate turbulence when passing through each partition plate 11; Mixing in the static mixing unit 5: The static mixing unit 5 forces the fluid to change its flow trajectory and slow down the flow rate through the grid-like barrier plate 53, forming vortex and shear effects to improve the mixing effect. Function of the flow disturbance component 6: The rotation of the driving runner 61 drives the stirring unit 62 to further disturb the fluid, ensuring more uniform fluid flow. At the same time, it prevents the accumulation of materials in the mixing unit. The dial rod 64 impacts the elastic plate 52 to enhance the turbulence effect of the fluid and ensure the uniformity and stability of the mixed liquid. Operation of the pneumatic driving component 7: The first pneumatic unit 711 is located outside the shunt tank 2 and drives the flow disturbance component 6 by jetting air flow. The second pneumatic unit 712 extends into the shunt tank 2 to further affect the fluid flow and enhance the mixing effect. Injection stage of the nozzle assembly 3: The second pneumatic component 72 provides a reverse thrust to cooperate with the connecting telescopic member 34 to adjust the up and down angle of the nozzle. The third pneumatic component 73 adjusts the injection direction and intensity through air flow pressure to ensure uniform atomization and precise injection of the injected liquid.

[0057] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions recorded in the foregoing embodiments or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
