Description

Technical Field

[0001] This utility model belongs to the field of nozzle technology, and in particular to a secondary atomizing nozzle within the same nozzle. Background Technology

[0002] In engineering workshops, environmental protection, medical, and landscaping industries, there are specific requirements for the physical properties of nozzles. Currently available two-fluid atomizing nozzles all perform single-pass atomization. While the spray is relatively fine, the actual atomized particles are relatively large, ranging from 20-100µm. For environments with high requirements for atomized particles, the finer the atomized particles from the nozzle, the better it can protect the product, more efficiently adsorb pollutants, and better meet the production requirements of the process. Summary of the Invention

[0003] The purpose of this invention is to address the aforementioned problems in existing technologies by proposing a secondary atomizing nozzle within the same nozzle, which features smaller atomized particles.

[0004] The objective of this utility model can be achieved through the following technical solutions: A secondary atomizing nozzle within a single nozzle includes a main body, a nozzle, an intermediate component, and a locking component. The main body has a liquid inlet connecting to a liquid channel, an air inlet connecting to a gas channel, a first mixing channel, and a first receiving port. The first receiving port and the first mixing channel, at their ends furthest from the nozzle, are both connected to the gas channel. The inner side of the first receiving port is connected to the outer side of one end of the nozzle, and a locking component is threadedly connected to the outer side of the first receiving port. The intermediate component is connected inside the first receiving port.

[0005] The intermediate component has a protruding end near the nozzle, and a first hole is formed on the protruding end; a second mixing channel is formed in the middle of the intermediate component. The interior of the second mixing channel is connected to the first hole. The nozzle has a nozzle and a second mixing channel; one end of the first hole is connected to the second mixing channel, and the other end is connected to the second mixing channel.

[0006] Preferably, the protruding end is placed inside the nozzle.

[0007] Preferably, the first receiving port is provided with a sealing groove, and a sealing ring is installed in the sealing groove.

[0008] Preferably, a second hole is provided at one end of the liquid channel near the axis, one end of the second hole is connected to the inside of the liquid inlet, and the other end is connected to the first mixing channel.

[0009] Preferably, the intermediate component is provided with an annular gas channel, and a third hole is provided at the end of the first mixing channel away from the nozzle. Both the fourth hole and the third hole can be used for gas passage.

[0010] Preferably, both the liquid inlet and the air inlet are provided with internal threads on their inner sides.

[0011] Compared with the prior art, the present invention has the following advantages: This invention designs a two-channel gas flow path. Pressure creates a first spray within the first and second mixing channels, which is then further dispersed in the third mixing channel, resulting in a finer spray. This secondary atomization reaction within the nozzle reduces particle size, achieving a spray particle size of less than 10µm. This broadens the nozzle's applicability, providing better adsorption and lower corrosiveness, thus expanding the product's application range. Attached Figure Description

[0017] like Figure 1 , Figure 2 , Figure 3 As shown, a secondary atomizing nozzle within the same nozzle includes a main body 1, a nozzle 2, an intermediate component 3, and a locking component 4; The main body 1 has a liquid inlet 5 connecting to a liquid channel 1001, an air inlet 6 connecting to a gas channel 1002, a first mixing channel 7, and a first receiving port 8. The first receiving port 8 and the end of the first mixing channel 7 away from the nozzle 2 are both connected to the gas channel 1002; The inner side of the first receiving port 8 is connected to the outer side of one end of the nozzle 2, and a locking member 4 is threadedly connected to the outer side of the first receiving port 8; an intermediate member 3 is connected inside the first receiving port 8. The intermediate component 3 has a protruding end 31 near the nozzle 2, and a first hole 9 is formed on the protruding end 31; a second mixing channel 10 is formed in the middle of the intermediate component 3; The interior of the second mixing channel 10 is connected to the first hole 9; The nozzle 2 is provided with an orifice and a third mixing channel 11; one end of the first hole 9 is connected to the third mixing channel 11, and the other end is connected to the second mixing channel 10.

[0018] In this invention, from a spatial perspective, although the first mixing channel 7 and the second mixing channel 10 are inside different parts, they can form a mixing space after assembly.

[0019] The working principle of this utility model is as follows: Liquid enters the nozzle through the inlet 5 under a certain pressure, and then enters the first mixing channel 7 through the second hole 14. Gas enters the nozzle through the air inlet 6 under a certain pressure, and then splits into two channels. One channel enters the first mixing channel 7 through the third hole 17 and mixes with the liquid in the first mixing channel 7 to form the first liquid mist mixture, thus forming the first spray. Due to pressure, the first spray passes through the second mixing channel 10 and the first hole 9 into the third mixing channel 11. The gas from the air inlet 6 enters the third mixing channel 11 through the fourth hole 16, and mixes with the first spray entering the third mixing channel 11 to form the second mixing atomization. The atomized body after the second mixing is sprayed out through several nozzles 15 of the nozzle 2.

[0020] like Figure 1 As shown, the outer side of the protruding end 31 has a slope and is placed inside the nozzle 2.

[0021] In this invention, by positioning the protruding end 31 forward, the outer gas can effectively disperse the spray exiting from the protruding end 31. If the distance between the front end of the protruding end and the nozzle is too far, and the third mixing channel 11 is too long, the spray in a confined space may form larger spray particles before being sprayed out. By positioning it forward and setting the distance within a reasonable range, the spray is effectively dispersed by the gas, allowing it to be sprayed out from each nozzle 15, thus ensuring the size of the sprayed spray particles.

[0022] The protruding end 31 has a slope, and the distance between it and the inside of the nozzle 2 is smaller. This design can effectively compress the gas, and the gas can have greater impact energy after passing through a smaller outlet under pressure. It can disperse the spray particles to below 10μm before spraying, which meets the environmental requirements of industrial production, medical and other applications.

[0023] like Figure 1 As shown, the first receiving port 8 is provided with a sealing groove 12, and a sealing ring 13 is installed in the sealing groove 12. By setting the sealing groove 12 and the sealing ring 13, the sealing performance of the first mixing channel 7 and the second mixing channel 10 at the connection point is improved, preventing the spray that was first dispersed from overflowing from the small gaps.

[0024] like Figure 1 As shown, a second hole 14 is provided at one end of the liquid channel 1001 near the axis. One end of the second hole 14 is connected to the inside of the liquid inlet 5, and the other end is connected to the first mixing channel 7.

[0025] like Figure 1 , Figure 3 As shown, the intermediate component 3 is provided with a fourth hole 16 and the first mixing channel 7 is provided with a third hole 17 at the end away from the nozzle 2. Both the fourth hole 16 and the third hole 17 can be connected by gas.

[0026] In this invention, a second hole 14 and a third hole 17 are provided. Liquid becomes finer after flowing through the second hole 14, making it easier to disperse into small particles. Gas, due to pressure, experiences a greater impact force when passing through the smaller third hole 17.

[0027] In this invention, gas, under pressure, enters the first receiving port 8 after passing through the air inlet 6. Since the first receiving port 8 is relatively large and the fourth hole 16 is relatively small, the gas pressure increases again after the flow from large to small, accelerating the gas's speed through the fourth hole 16. This results in a greater impact force that further impacts the spray, making the spray particles even smaller. The finer the spray particles, the better the dirt absorption, and it can also reduce corrosion of some metals, making it suitable for a wider range of production environments.

[0028] like Figure 1 As shown, both the liquid inlet 5 and the air inlet 6 have internal threads on their inner sides. These internal threads facilitate connection to liquid and gas pipes in various environments.

[0029] All of the above components are general standard parts or components known to those skilled in the art. Their structure and principles can be learned by those skilled in the art through technical manuals or conventional experimental methods.

[0030] The specific embodiments described herein are merely illustrative examples illustrating the spirit of this utility model. Those skilled in the art to which this utility model pertains may make various modifications or additions to the described specific embodiments or use similar methods to substitute them, without departing from the spirit of this utility model or exceeding the scope defined by the appended claims.

[0031] Although this document frequently uses terms such as main body, nozzle, intermediate part, protruding end, locking part, liquid inlet, air inlet, first mixing channel, first receiving port, first hole, second mixing channel, and third mixing channel, the possibility of using other terms is not excluded. These terms are used merely for the convenience of describing and explaining the essence of this utility model; interpreting them as any additional limitation would contradict the spirit of this utility model.
