Description

Technical Field

[0001] This utility model relates to the field of atomizing nozzle technology, specifically a spray atomizing nozzle. Background Technology

[0002] Spraying is a commonly used technical device widely applied in both civilian and industrial settings. Examples include fogging systems installed around construction sites, spray trucks used to suppress PM2.5 levels, spiral nozzles installed inside chemical absorption towers, and jet injectors used to improve gas-liquid mixing.

[0003] Atomization in nozzles typically involves a high-pressure pump delivering liquid into the nozzle, where a special structural design provides significant resistance, thus breaking the liquid apart and atomizing it into fine droplets. Such nozzles generally have high resistance and high energy consumption. Utility Model Content

[0004] The purpose of this invention is to provide a spray atomizing nozzle to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a spray atomizing nozzle, including a connecting pipe with an inlet, a limiting ring on the outer wall of the connecting pipe, an inner guide tube connected to the connecting pipe, and fixing plates equidistantly installed on the outer circumference of the inner guide tube. An outer guide tube is fixedly sleeved on the outside of the inner guide tube by the fixing plates. Specifically, the connecting section is used to connect with the upstream feed pipe to receive process materials; the limiting ring is located below the connecting pipe to limit the connection depth between the connecting pipe and the feed pipe; the fixing plate is used to fix the relative positions of the inner and outer guide tubes and to reserve a gap between the inner and outer guide tubes. During operation, the upstream feed enters the nozzle from the inlet, flows through the inner guide tube and is guided outward at high speed and sprayed out. At this time, a negative pressure is formed between the inner and outer guide tubes. The surrounding air enters the nozzle through the gap between the inner and outer guide tubes, mixes with the sprayed agent, and is then transported outward.

[0006] Preferably, the connection between the connecting pipe and the upstream feeding pipe can be a threaded connection, a socket connection, a quick connector, or a flange connection.

[0007] Preferably, the inner guide tube can be either a straight-through type or a vortex type.

[0008] Preferably, the outer guide tube includes a first straight pipe section, a reduction section, a second straight pipe section, and an air intake.

[0009] Preferably, the air intake on the outer guide tube is an integral opening, but it can also be a partial opening.

[0010] Preferably, the angle between the reduced section and the second straight pipe section on the outer guide tube is 0-80 degrees.

[0011] Preferably, the inner diameter of the second straight pipe section on the outer guide tube is larger than the inner diameter of the inner guide tube.

[0012] Preferably, the outer guide tube and the fixing plate are connected by threads.

[0013] This utility model provides a spray atomizing nozzle. It has the following beneficial effects:

[0014] (1) This utility model achieves efficient atomization without external power assistance by using the negative pressure effect between the connecting pipe and the outer guide tube, thereby reducing energy consumption and improving atomization efficiency.

[0015] (2) Through the optimized design of the structure, the overall weight of the nozzle is reduced, the installation is more convenient, and it has the characteristics of low resistance, economical and energy-saving operation, and excellent mixing effect. Attached Figure Description

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Examples of the embodiments are shown 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. Example

[0022] A preferred embodiment of the spray atomizing nozzle provided by this utility model is, for example... Figure 1-2 As shown: A spray atomizing nozzle includes a connecting pipe 2 with an inlet 1 and a limiting ring 3 on its outer wall. The connecting pipe 2 is connected to an inner guide tube 5, and fixing plates 4 are equidistantly installed on the outer circumference of the inner guide tube 5. An outer guide tube 6 is fixedly sleeved on the outside of the inner guide tube 5 through the fixing plates 4. Specifically, the connecting section 2 is used to connect to the upstream feed pipe to receive process materials; the limiting ring 3 is located below the connecting pipe 2 to limit the connection depth between the connecting pipe 2 and the feed pipe; the fixing plates 4 are used to fix the relative positions of the inner guide tube 5 and the outer guide tube 6 and reserve a gap between the inner guide tube 5 and the outer guide tube 6. During operation, the upstream feed enters the nozzle from the inlet 1, flows through the inner guide tube 5 and is guided outward at high speed and sprayed out. At this time, a negative pressure is formed between the inner guide tube 5 and the outer guide tube 6. The surrounding air enters the nozzle through the gap between the inner guide tube 5 and the outer guide tube 6, mixes with the sprayed agent, and is then transported outward.

[0023] The connection between connecting pipe 2 and the upstream material supply pipe is a socket connection.

[0024] The inner guide tube 5 can be used for straight-through material conveying.

[0025] The outer guide tube includes a first straight pipe section 61, a reduction section 62, and a second straight pipe section 63.

[0026] The air intake 64 on the outer guide tube 6 is an integral opening.

[0027] The angle between the reduced section 62 and the second straight pipe section 63 on the outer guide tube 6 is 0-80 degrees.

[0028] The inner diameter of the second straight pipe section 63 on the outer guide tube 6 is larger than the inner diameter of the inner guide tube 5.

[0029] The outer guide tube 6 and the fixed plate 4 are connected by threads.

[0030] When the spray atomizing nozzle provided in this case is connected to the upstream material supply pipe, the airflow enters from the inlet 1, passes through the straight section of the inner guide tube 5, and is jetted out at high speed. At this time, a negative pressure is formed between the inner guide tube 5 and the outer guide tube 6. The surrounding air enters through the air inlet of the outer guide tube, accelerates at the shrinkage port, i.e., the shrinkage section 62, mixes with the material airflow, and is then sprayed outward. Example

[0031] Please see Figures 1-3Furthermore, based on Embodiment 1, the following alternative spray atomizing nozzle provided in this case includes a connecting pipe 2, which has an inlet 1 and a limiting ring 3 on its outer wall. An inner guide tube 5 is connected to the connecting pipe 2, and fixing plates 4 are equidistantly installed on the outer circumference of the inner guide tube 5. An outer guide tube 6 is fixedly sleeved on the outside of the inner guide tube 5 through the fixing plates 4. Specifically, the connecting section 2 is used to connect to the upstream feed pipe to receive process materials; the limiting ring 3 is located below the connecting pipe 2. The square is used to limit the connection depth between the connecting pipe 2 and the main feed pipe; the fixing plate 4 is used to fix the relative position of the inner guide cylinder 5 and the outer guide cylinder 6, and to reserve a gap between the inner guide cylinder 5 and the outer guide cylinder 6. During operation, the upstream feed enters the nozzle from the inlet 1, flows through the inner guide cylinder 5 and is guided outward at high speed and sprayed out. At this time, a negative pressure is formed between the inner guide cylinder 5 and the outer guide cylinder 6. The surrounding air enters the nozzle through the gap between the inner guide cylinder 5 and the outer guide cylinder 6, mixes with the sprayed agent, and is then transported outward.

[0032] The connection between connecting pipe 2 and the upstream material supply pipe is a threaded connection.

[0033] The inner guide tube 5 can be used for straight-through material conveying.

[0034] The outer guide tube includes a first straight pipe section 61, a shrinkage section 62, a second straight pipe section 63, and an air intake 64.

[0035] The air intake 64 on the outer guide tube 6 is a partial opening.

[0036] The angle between the reduced section 62 and the second straight pipe section 63 on the outer guide tube 6 is 0-80 degrees.

[0037] The inner diameter of the second straight pipe section 63 on the outer guide tube 6 is larger than the inner diameter of the inner guide tube 5.

[0038] The outer guide tube 6 and the fixed plate 4 are connected by threads.

[0039] When the spray nozzle provided in this case is connected to the upstream feed pipe, the airflow enters from inlet 1, passes through the straight section of the inner guide tube 5, and is ejected at high speed. At this time, a negative pressure is formed between the inner guide tube 5 and the outer guide tube 6. The surrounding air enters through the air intake 64 of the outer guide tube 6, accelerates at the reduction section 62, mixes with the material airflow, and is then sprayed outward through the second straight section 63.
