Description

Technical Field

[0001] This application relates to the field of chemical equipment technology, and in particular to a nozzle device and a stirring device. Background Technology

[0002] In the chemical industry, especially in the semiconductor field, many materials will quickly precipitate and agglomerate in solvents. Traditional inward-extending oblique-cut tube feeding inevitably forms large agglomerates, resulting in poor dispersion and making it difficult to mix evenly in subsequent stirring. Utility Model Content

[0003] In view of this, the purpose of this application is to provide a nozzle device and a stirring device to achieve uniform dispersion of materials.

[0004] To achieve the above objectives, this application provides a nozzle device comprising:

[0005] The connecting component includes a connecting body and a branch pipe. The connecting body has a collection channel inside, which is used to collect the input materials. The branch pipe is connected to the connecting body.

[0006] Multiple nozzles, at least one of which is connected to a branch pipe;

[0007] The connecting components are configured such that the axial direction of each nozzle is parallel or collinear with the axial direction of the connecting body.

[0008] In a preferred embodiment, the connecting body includes an inlet and a center outlet disposed opposite to each other, forming a flow collection channel between the inlet and the center outlet, and a branch pipe is connected to the outer peripheral surface of the connecting body, and the branch pipe is provided with a branch flow channel communicating with the flow collection channel.

[0009] In a preferred embodiment, the nozzle includes a first nozzle and a second nozzle, the first nozzle being connected to the central outlet and the second nozzle being connected to the branch pipe.

[0010] In a preferred embodiment, there are multiple second nozzles, which are evenly distributed along the circumference of the connecting body.

[0011] In a preferred embodiment, the first nozzle is threadedly connected to the central outlet, and the second nozzle is threadedly connected to the branch pipe, which is a bent pipe.

[0012] In a preferred embodiment, the branch pipe is threaded or integrally formed with the connecting body.

[0013] In a preferred embodiment, the nozzle is an atomizing nozzle, which includes a plurality of spray holes.

[0014] In a preferred embodiment, the spray angle of the nozzle relative to the axis of the nozzle is 0° to 30°.

[0015] Based on the same inventive concept, this application also provides a stirring device, comprising:

[0016] Tank body;

[0017] A stirring device, including a stirring shaft and stirring blades disposed on the stirring shaft, wherein the stirring blades and the stirring shaft are rotatably disposed within a tank; and

[0018] In any of the above embodiments, the nozzle device is mounted on the tank body, and the spray direction of the nozzle device is configured to avoid the stirring shaft and the stirring blade.

[0019] In a preferred embodiment, the nozzle device is mounted on the top of the tank, and the spray direction of the nozzle device is configured to avoid the side wall of the tank.

[0020] The nozzle device of this application collects materials through the flow collection channel of the connecting body in the connecting assembly. With the connection of branch pipes to multiple nozzles, and the constraint of the connecting assembly on the parallel or collinearity of the axis of each nozzle with the axis of the connecting body, it can achieve uniform material dispersion. It is suitable for feeding materials that are prone to precipitation and have limited feeding space. Since the spray direction of the nozzle is concentrated and controllable, it can avoid the stirring shaft and tank wall, so as to achieve uniform material dispersion on the liquid surface and precipitation of solid particles. With the addition of stirring, the precipitated solid particles can be quickly dispersed. It can adapt to the scenario of limited feeding space and improve the uniformity and efficiency of material processing. Attached Figure Description

[0030] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with specific embodiments and the accompanying drawings.

[0031] It should be noted that, unless otherwise defined, the technical or scientific terms used in the embodiments of this application should have the ordinary meaning understood by one of ordinary skill in the art to which this application pertains. The terms "first," "second," and similar terms used in the embodiments of this application do not indicate any order, quantity, or importance, but are merely used to distinguish different components. Terms such as "comprising" or "including" mean that the element or object preceding the word encompasses the elements or objects listed after the word and their equivalents, without excluding other elements or objects. Terms such as "connected" or "linked" are not limited to physical or mechanical connections, but can include electrical connections, whether direct or indirect. Terms such as "upper," "lower," "left," and "right" are only used to indicate relative positional relationships; when the absolute position of the described object changes, the relative positional relationship may also change accordingly.

[0032] In the chemical industry, especially in the semiconductor field, there are many materials that readily precipitate and agglomerate in solvents. Related feeding technologies present several challenges. For example, in traditional internally extended oblique-cut tube feeding technology, materials tend to form large clumps, resulting in poor dispersion and making subsequent mixing difficult and uneven. Similarly, in spray ball feeding technology, even with the smallest spray ball angle, materials can still be sprayed onto the agitator blades or tank walls, causing sediment buildup and equipment contamination. Furthermore, if zero-angle nozzles are used directly, these are mostly standardized mass-produced products, and their fixed flow rate and pressure parameters are difficult to adapt to the diverse feeding requirements of the chemical and semiconductor industries.

[0033] Therefore, in order to address at least one of the problems in related technologies, such as easy agglomeration of materials, uncontrolled spray range, mismatch between flow rate and pressure, and poor spatial adaptability, a compact nozzle device using a combination of multiple nozzles to adapt to the flow rate is provided.

[0034] like Figures 1 to 4As shown, this application embodiment provides a nozzle device 100 for feeding materials that are prone to precipitation and have limited feeding space in the chemical or semiconductor industries. The nozzle device 100 includes a connecting assembly 10 and a plurality of nozzles 20. The connecting assembly 10 includes a connecting body 110 and a branch pipe 120. A collection channel 101 is provided inside the connecting body 110 for collecting the input material. The branch pipe 120 is connected to the connecting body 110. At least one nozzle 20 is connected to a corresponding branch pipe 120. The connecting assembly 10 is configured such that the axial direction of each nozzle 20 is parallel or collinear with the axial direction of the connecting body 110.

[0035] It should be noted that "multiple" refers to at least two. The connecting body 110 is a single integrated structure and a multi-port connector, with one connecting body 110 simultaneously connecting multiple nozzles 20. The flow collection channel 101 receives external materials via a pump or gas pressure conveying, ensuring that the materials stably enter each nozzle 20 under pressure. The axial direction of each nozzle 20 is parallel or collinear with the axial direction of the connecting body 110, so that all nozzles 20 are basically facing the same direction, and the spray direction of the nozzle orifice on each nozzle 20 can be low-angle or zero-angle spray.

[0036] Specifically, the nozzle device 100 of this application can be applied to scenarios in the chemical and semiconductor industries where materials that are prone to precipitation and have limited feeding space are being fed. In the connecting assembly 10, the collection channel 101 of the connecting body 110 receives materials via a pump or pneumatic conveying, ensuring stable material collection. Each nozzle 20 corresponds to a branch pipe 120, which works in conjunction with the connecting body 110 to divert material flow, meeting the need for simultaneous feeding from multiple nozzles 20. The axes of the multiple nozzles 20 are parallel or collinear with the axis of the connecting body 110, and the nozzles 20 are oriented in the same direction, allowing for concentrated and controllable material spraying, avoiding contact with the stirring shaft and tank wall, and ensuring uniform material dispersion on the liquid surface. Combined with stirring, this quickly disperses precipitated solid particles, improving the uniformity and efficiency of material processing.

[0037] The nozzle device 100 provided in this application embodiment collects materials through the collection channel 101 of the connecting body 110 in the connecting component 10, and connects the branch pipe 120 with multiple nozzles 20. The connecting component 10 also constrains the axial direction of each nozzle to be parallel or collinear with the axial direction of the connecting body 110, thereby realizing a combination of multiple nozzles. The material spraying direction is concentrated and controllable, so as to achieve uniform dispersion of materials on the liquid surface, reduce agglomeration, improve the material dispersion effect, and adapt to scenarios with limited feeding space.

[0038] like Figure 2As shown, in some embodiments, the connecting body 110 includes an inlet 111 and a central outlet 112 arranged axially opposite to each other, forming a flow collecting channel 101 between the inlet 111 and the central outlet 112. A branch pipe 120 is connected to the outer peripheral surface of the connecting body 110, and a branch flow channel 102 communicating with the flow collecting channel 101 is provided inside the branch pipe 120. Multiple branch outlets are opened on the outer peripheral surface of the connecting body 110, and each branch outlet communicates with the flow collecting channel 101. Each branch flow channel 102 corresponds to one branch outlet.

[0039] Specifically, the feed inlet 111 of the connecting body 110 receives externally conveyed materials, and guides the materials to the central discharge outlet 112 and the branch flow channel 102 of the branch pipe 120 through the collecting channel 101, thereby achieving reasonable material distribution. The relative arrangement of the feed inlet 111 and the central discharge outlet 112 ensures stable conveying of the main material flow. The branch pipe 120 is connected to the outer circumference of the connecting body 110, so that the branch flow channel 102 and the collecting channel 101 are smoothly connected, avoiding material stagnation in the flow channel and causing sedimentation.

[0040] In some embodiments, the nozzle 20 includes a first nozzle 201 and a second nozzle 202, the first nozzle 201 being connected to the central outlet 112 and the second nozzle 202 being connected to the branch pipe 120.

[0041] Specifically, the first nozzle 201 is connected to the central outlet 112 to receive the main material flow from the collecting channel 101. The second nozzle 202 is connected to the branch pipe 120 to receive the diverted material from the branch channel 102. The two work together to achieve multi-path feeding. Addressing the issue of insufficient flow from a traditional single nozzle, the combination of the first nozzle 201 and the second nozzle 202 allows for adjustment of the total feed rate according to operating conditions, meeting the requirements for different material processing volumes. Simultaneously, the first nozzle 201 and the second nozzle 202 correspond to the main channel and the branch channel respectively, ensuring a clear dispersion path for the material during transport and avoiding mutual interference. Combined with the constraint of the nozzle axis direction by the connecting assembly 10, the spray directions of both nozzles are aligned, avoiding the stirring shaft and tank wall, allowing the material to be evenly dispersed on the liquid surface. This, combined with stirring, quickly disperses sediment and prevents clumping.

[0042] like Figure 3 As shown, in some embodiments, there are multiple second nozzles 202, and the multiple second nozzles 202 are evenly distributed along the circumference of the connecting body 110.

[0043] Specifically, multiple second nozzles 202 are evenly distributed circumferentially along the connecting body 110, allowing the diverted material to be sprayed from different directions but in the same direction, forming a uniform material dispersion area. This distribution solves the problem of limited coverage of a single branch nozzle. The circumferentially uniform layout ensures more comprehensive dispersion of material on the liquid surface, avoiding sedimentation and agglomeration caused by local material concentration. At the same time, the uniform distribution balances the forces among the second nozzles 202, reducing vibration caused by material impact and improving the stability of the device. Combined with the constraint of the connecting component 10 on the axial direction, the multiple second nozzles 202 spray in the same direction and avoid the stirring components and tank walls, working in synergy with the first nozzle 201 to further enhance the material dispersion effect and meet the high requirements for material uniformity. The total material conveying flow rate can be flexibly adjusted by increasing or decreasing the number of second nozzles 202 (e.g., 2 to 4), adapting to the diverse working conditions in the chemical and semiconductor fields.

[0044] like Figure 4 As shown, in some other embodiments, the number of second nozzles 202 may also be one.

[0045] In some embodiments, the first nozzle 201 is threadedly connected to the central outlet 112, and the second nozzle 202 is threadedly connected to the branch pipe 120, wherein the branch pipe 120 is a bent pipe.

[0046] Specifically, the first nozzle 201 and the central outlet 112, and the second nozzle 202 and the branch pipe 120 are all connected by threads to facilitate installation and disassembly, meeting the high requirements for equipment cleaning and maintenance in the chemical and semiconductor industries. When processing materials that are prone to precipitation, the nozzles are prone to residue. The threaded connection allows the nozzles to be quickly disassembled for cleaning or replacement, avoiding blockage and precipitation pollution caused by residue accumulation. At the same time, the threaded connection has good sealing performance, effectively preventing material leakage and ensuring that all material can be sprayed through the nozzles under the pressure of the pump or air, reducing waste and pollution. Compared with fixed connections, the threaded connection design is more flexible, allowing different specifications of nozzles to be replaced according to the material characteristics, improving the adaptability of the device to different working conditions. The branch pipe 120 is a bent pipe, and its bending angle can be adjusted according to the installation space. For example, a 90° turn can be used to ensure that the axis of the second nozzle 202 is parallel to the axis of the connecting body 110, achieving consistency in the spray direction of each nozzle.

[0047] Optionally, the branch pipe 120 and the connecting body 110 are threaded together or integrally formed.

[0048] Specifically, the threaded connection between the branch pipe 120 and the connecting body 110 allows for easy replacement of branch pipes 120 with different specifications according to working conditions, flexibly adjusting the diversion path and flow rate to adapt to changes in material processing volume. The integrated molding method, on the other hand, offers higher structural strength and sealing, can withstand higher material conveying pressures, and avoids material leakage due to connection gaps, making it suitable for high-pressure feeding scenarios. These two connection methods address the needs for flexibility and high-pressure stability, respectively, solving the problem that traditional standardized nozzles cannot adapt to diverse working conditions. Considering the complex requirements of the chemical and semiconductor industries, the threaded connection facilitates maintenance and cleaning, while the integrated molding ensures long-term stable operation. Both can work with the connecting assembly 10 to constrain the nozzle direction, ensuring that material spray avoids the stirring shaft and tank wall, thus improving dispersion.

[0049] In some embodiments, the nozzle 20 is an atomizing nozzle, and the nozzle 20 includes a plurality of nozzle holes 210.

[0050] Optionally, the diameter of the nozzle 210 is 0.2 to 0.5 mm. For example, the diameter of the nozzle 210 can be 0.2 mm, 0.3 mm, 0.4 mm or 0.5 mm, etc.

[0051] Optionally, the spray angle of the nozzle 210 relative to the axis of the nozzle 20 is 0° to 30°. For example, the spray angle of the nozzle 210 can be 0°, 15°, 20°, 25°, 30°, etc.

[0052] Specifically, the nozzle employs an atomization design, dispersing the material into fine droplets during spraying. This solves the problem of large agglomerations formed by traditional inward-extending oblique-cut tube feeding, increases the contact area between the material and the solvent, and reduces aggregation during precipitation. The multiple nozzles 210 further enhance the atomization effect, ensuring more uniform material dispersion. Considering the need to process materials prone to precipitation, the atomization design ensures the material is already dispersed upon entering the liquid surface. Combined with stirring, this allows for rapid formation of a homogeneous system, further improving processing efficiency.

[0053] In addition, the diameter of the nozzle 210 is 0.2–0.5 mm. This range ensures smooth material passage, avoiding clogging caused by excessively small orifices, while also enhancing atomization through appropriate flow velocity, reducing material residue within the nozzle 210 and lowering the risk of sedimentation and clogging. The spray angle of the nozzle 210 is limited to 0°–30°, which is a low-angle or zero-angle spray. This disperses the material while preventing it from contacting the stirring shaft and tank wall. The 0°–30° angle range ensures concentrated material spray direction. Under the constraint of the nozzle axis direction by the connecting component 10, it can accurately avoid the stirring shaft, impeller, and tank wall, preventing sedimentation and equipment contamination caused by material adhesion. At the same time, this angle range, while ensuring obstacle avoidance, enhances the dispersion range of the material on the liquid surface through appropriate diffusion, avoiding localized concentration caused by single-direction spray. The coordinated action of multiple nozzles makes the material dispersion more uniform.

[0054] like Figure 5 As shown, embodiments of this application also provide a stirring device 1, which includes a tank 11, a stirring device 2, and a nozzle device 100 as described in any of the above embodiments. The stirring device 2 includes a stirring shaft 21 and stirring blades 22 disposed on the stirring shaft 21, the stirring blades 22 and the stirring shaft 21 being rotatably disposed within the tank 11. The nozzle device 100 is mounted on the tank 11, and the spray direction of the nozzle device 100 is configured to avoid the stirring shaft 21 and the stirring blades 22.

[0055] Specifically, the mixing device 1 is designed for materials prone to precipitation in the chemical and semiconductor industries. The tank 11 provides a closed space for material processing, and the mixing device 2 drives the mixing blades 22 to rotate via the mixing shaft 21, achieving mixing and dispersing of the materials. The nozzle device 100 is installed on the tank 11, and its spray direction avoids the mixing shaft 21 and the mixing blades 22, solving the precipitation and adhesion problem caused by material contact with the mixing device in traditional feeding methods. The nozzle device 100 uses multi-path, low-angle atomization spray to evenly disperse the material on the liquid surface. The precipitated solid particles are not prone to agglomeration due to their good dispersibility, and the mixing blades 22 can quickly disperse them into a homogeneous system. This mixing device 1 combines the dispersing advantages of the nozzle device 100 and the mixing capacity of the mixing device 2, effectively solving the problems of agglomeration and poor dispersion in the processing of easily precipitated materials, improving processing efficiency and material uniformity.

[0056] Furthermore, the nozzle device 100 is installed on the top of the tank 11, and the spray direction of the nozzle device 100 is configured to avoid the side wall of the tank 11.

[0057] Specifically, the nozzle device is installed at the top of the tank 11, allowing the material to be sprayed vertically downwards. Combined with its low-angle spray characteristics, it more easily avoids the stirring shaft 21 and stirring blades 22 located at the center of the tank 11, while also avoiding the side walls of the tank 11. This solves the problem of sedimentation and adhesion caused by material spraying onto the tank wall in traditional feeding methods. The top installation method makes full use of the upper space of the tank 11, adapting to scenarios with limited feeding space and avoiding interference with other internal components of the tank 11. The spray direction avoids the side walls, ensuring that all material enters the core mixing area at the liquid surface. Combined with the rotation of the stirring device 2, the material can quickly mix with the solvent, and any precipitated sediment is promptly dispersed, reducing residue on the tank wall, lowering cleaning difficulty, and meeting the high cleanliness requirements of the chemical and semiconductor industries, thus improving the quality of material handling.
