Description

Technical Field

[0001] This utility model belongs to the field of atomizing nozzle technology, and in particular relates to a high-efficiency adjustable atomizing nozzle for high-viscosity adhesives. Background Technology

[0002] The atomization and disintegration of high-viscosity fluids have significant applications in multiple industrial sectors. In the chemical industry, fluid atomization is a crucial step in physical performance testing, directly impacting the accuracy and reliability of measurement results. In boiler engineering, the atomization effect of high-viscosity liquid fuels plays a decisive role in boiler stability, combustion efficiency, and emission control. In agricultural irrigation and pesticide spraying, air atomization methods with specific flow rates and airflow configurations can achieve uniform spraying of solutions by impacting metal discs, thereby improving crop protection and water resource utilization efficiency. In the production of engineered wood products, especially in the production of high-strength engineered wood products made from cotton stalks, the atomization quality in the adhesive spraying stage plays a vital role in the uniform distribution and good adhesion of the adhesive, ensuring not only uniform coverage but also significantly improving bonding strength and further enhancing the physical and mechanical properties of the boards. Therefore, nozzle design plays a critical role in the process of manufacturing engineered wood products from cotton stalks.

[0003] As a key component in the atomization process, atomizing nozzles currently come in several mature types, such as throat nozzles, LPL-type nozzles, HW-type nozzles, and bubble atomizing nozzles. These nozzles typically enhance the atomization effect by increasing the flow rate and pressure of the external medium. In the production of cotton stalk engineered wood panels, the amount of adhesive sprayed is large, the viscosity of the adhesive is high and fluctuating, and the spray radius also needs to be adjusted, which places higher demands on the performance of the nozzles. However, for high-viscosity fluids, especially when a large atomization volume is required, simply increasing the flow rate and pressure does not always achieve the ideal atomization effect, and may even lead to uneven spraying or insufficient atomization.

[0014] The high-efficiency adjustable atomizing nozzle for high-viscosity adhesives of this invention has the following advantages:

[0015] This invention utilizes the rotation of the outer pipe to enable the inner flow pipe to reciprocate, thereby altering the size of the primary mixing chamber (the inner flow pipe). This allows for adaptation to liquids of varying viscosities, achieving the desired atomization particle size and resulting in superior atomization.

By performing two stages of liquid breaking atomization and three stages of mixing and breaking atomization, high-viscosity liquids can be fully atomized with smaller atomized particle sizes.

[0029] like Figure 1-5As shown, this utility model discloses a high-efficiency adjustable atomizing nozzle for high-viscosity adhesives, comprising a rotating outer pipe 1, one end of which is connected to a two-fluid outer pipe 2, and the other end of which is connected to a secondary two-fluid mixing pipe 6. Airflow pipes are provided on both sides of the two-fluid outer pipe 2. An atomizing nozzle 7 is connected to the end of the secondary two-fluid mixing pipe 6 away from the rotating outer pipe 1. A liquid flow breaking pipe 5 is connected to the end of the two-fluid outer pipe 2 away from the rotating outer pipe 1. A primary two-fluid mixing pipe 3 is provided in the inner cavity of the rotating outer pipe 1, and an inner flow pipe 4 is provided in the inner cavity of the two-fluid outer pipe 2. One end of the rotating outer pipe 1 is provided with a first internal thread groove 8, and the surface of the secondary two-fluid mixing pipe 6 is provided with a first external thread 10. The first external thread 10 is threadedly connected to the first internal thread groove 8. The end of the secondary two-fluid mixing pipe 6 away from the atomizing nozzle 7 is provided with a first insertion hole 16 corresponding to that of the primary two-fluid mixing pipe 3. The end of the secondary two-fluid mixing pipe 6 away from the rotating outer pipe 1 is provided with a second internal thread groove 11. The end of the atomizing nozzle 7 is provided with a threaded head 12, which is threadedly connected to the second internal thread groove 11. The surface of the rotating outer pipe 1 is provided with a first fixing hole 9 that communicates with the first internal thread groove 8. A fixing screw is connected to the internal thread of the first fixing hole 9. The inner cavity of the rotating outer pipe 1 away from the secondary two-fluid mixing pipe 6 is provided with a third internal thread groove 17. The surface of the primary two-fluid mixing pipe 3 is provided with a second external thread 13, which is threadedly connected to the third internal thread groove 17. A sealing ring is provided at the end of the primary two-fluid mixing pipe 3 away from the secondary two-fluid mixing pipe 6. Multiple second fixing holes 15 arranged in a circumferential array are provided. The end of the two-fluid outer pipe 2 extends into the inner cavity of the rotating outer pipe 1, and a locking screw is threaded into the second fixing hole 15. The end of the locking screw contacts the end surface of the two-fluid outer pipe 2. Multiple positioning blocks 20 arranged in a circumferential array are provided on the side wall of the inner flow pipe 4 away from the first-stage two-fluid mixing pipe 3. Multiple positioning grooves corresponding to the positioning blocks 20 are provided in the inner cavity of the two-fluid outer pipe 2. The size of the positioning block 20 matches the size of the positioning groove, and the inner... The end of the flow pipe 4 away from the primary two-fluid mixing pipe 3 is provided with a second insertion hole 19 corresponding to the liquid flow breaking pipe 5. The end of the two-fluid outer pipe 2 away from the rotating outer pipe 1 is provided with a fourth internal thread groove 18. The surface of the liquid flow breaking pipe 5 is provided with a third external thread 14, which is threadedly connected to the fourth internal thread groove 18. The side wall of the liquid flow breaking pipe 5 located at one end of the inner flow pipe 4 is provided with two symmetrically distributed through holes 21, and the interior of the liquid flow breaking pipe 5 is provided with guide grooves that are respectively connected to the two through holes 21.

[0030] The working principle of this high-efficiency adjustable atomizing nozzle for high-viscosity adhesives is as follows: Liquid flows in through the liquid flow breaking pipe 5 and flows out through two through holes 21 at the bottom for the first liquid breaking. The liquid flow breaking pipe 5 has a guide groove at the bottom to enhance the centrifugal force of the liquid and ensure that the liquid flow rate of the two through holes 21 is the same. When the outflowing liquid collides with the inner wall of the inner flow pipe 4, it undergoes a second liquid breaking. The pipes on both sides of the two-fluid outer pipe 2 are airflow pipes, which divide the airflow into two parts. One part flows down along the outer wall of the inner flow pipe 4, and the other part enters the inner flow pipe 4 to mix and break the liquid for the second breaking (first atomization) and enter the first-stage two-fluid mixing pipe 3. When the liquid flows out of the pipe of the first-stage two-fluid mixing pipe 3, it undergoes a second mixing and breaking (second atomization). At this time, it enters the second-stage two-fluid mixing pipe 6, where the liquid undergoes a third mixing and breaking (third atomization) with the previous downward airflow and is ejected from the atomizing nozzle 7.

[0031] This invention utilizes the rotation of the outer pipe 1 to enable the inner flow pipe 4 to reciprocate, thereby altering the size of the primary mixing chamber (inner flow pipe 4). This allows for adaptation to liquids of varying viscosities, achieving the desired atomized particle size and resulting in superior atomization. The secondary two-fluid mixing pipe 6 can rotate axially, changing the size of the secondary mixing chamber (primary two-fluid mixing pipe 3) and thus altering the atomization cone angle (the angle at which the atomized gas is ejected). Symmetrical gas introduction on both sides ensures stable internal pressure and provides sufficient gas flow. The liquid flow breaking pipe 5 has a guide groove at its bottom to enhance the liquid's centrifugal force and ensure equal liquid flow rates at both through-holes 21. Performing two liquid breaking atomization stages and three mixing breaking atomization stages allows for thorough atomization of high-viscosity liquids and results in smaller atomized particle sizes.
