Description

Technical Field

[0001] This utility model relates to the technical field of tobacco equipment accessories, and in particular to a dual-medium nozzle atomization effect verification device. Background Technology

[0002] In the tobacco processing industry, the flavoring process is a crucial step. The tobacco shreds are evenly loosened by the rotation of the drum, and the flavoring agents are atomized by compressed air through a dual-media nozzle and evenly sprayed onto the surface of the tobacco shreds, thus achieving the flavoring process. However, current flavoring processes face several challenges in controlling the atomization effect of the dual-media nozzles: the compressed air pressure and nozzle gap directly affect the atomization effect, consequently impacting the uniformity of flavoring. If the atomization pressure is too low, the liquid atomization is incomplete, hindering the tobacco shreds' adsorption of the liquid and easily resulting in wet clumps of tobacco. If the atomization pressure is too high, the sprayed liquid mist will disperse the material, reaching the inner wall of the drum and causing a large amount of tobacco shreds to adhere to the drum wall. Furthermore, under excessively high atomization pressure, the liquid droplet size is too small, and the dispersed droplets are easily discharged under negative pressure by the dehumidifying fan, resulting in liquid waste. Furthermore, during production, the nozzle's spray distance, atomization radius, atomization effect, and whether there is any dripping from the nozzle cannot be observed. Currently, the only way to test the nozzle's atomization effect is to use water during production maintenance and cleaning time, and observe it from outside the roller. This process requires multiple people to work together, posing certain safety hazards. Moreover, due to the enclosed environment of roller-type equipment, the observation window is very short, making it impossible to clearly observe the atomization effect. If the atomization effect is poor during production, it directly affects the product's process quality, causing serious quality risks and hidden dangers. Existing technology lacks a device that can effectively simulate actual working conditions, accurately verify the atomization effect of dual-media nozzles, and adjust the nozzle angle, control pressure, and flow rate. This makes it difficult to meet the needs of precise control and detection of the atomization effect of dual-media nozzles in the tobacco processing and flavoring process. Utility Model Content

The liquid storage tank 7 stores the test liquid and is equipped with an external water source interface to allow the test liquid to be injected into the liquid storage tank 7 through the external water source interface. The water outlet 8 is located at the bottom of the liquid storage tank 7, through which the test liquid in the liquid storage tank 7 can be discharged. The ball valve I9 ​​can control the flow of the test liquid, making it convenient to cut off the pipeline when debugging, maintaining or replacing the test liquid in the liquid storage pipeline.

The top end of the yaw angle adjusting screw 2002 is hinged to the bottom end of the nozzle fastening assembly. When it is necessary to adjust the yaw angle... When adjusting the angle of the dual-medium nozzle 19 in the horizontal direction, loosen the yaw angle adjustment knob 2005 and rotate the yaw angle adjustment screw 2002 so that the yaw angle mark 2003 points to a certain angle value on the surface of the angle scale 2004. Tighten the yaw angle adjustment knob 2005 to complete the angle adjustment of the dual-medium nozzle 19 in the horizontal direction. The bottom end of the pitch angle adjustment screw 2006 passes through the pitch angle adjustment nut 2007 and the arc-shaped sliding groove 2008 opened on the surface of the base 2001 in sequence, and is fastened to the base 2001 by a gasket and the pitch angle adjustment knob 2009.

The top of the pitch angle adjustment screw 2006 is hinged to the bottom of the nozzle fastening component. When it is necessary to adjust the angle of the dual-medium nozzle 19 in the vertical direction, loosen the pitch angle adjustment knob 2009 and then rotate the pitch angle adjustment nut 2007, so that the pitch angle adjustment nut 2007 is rotated to a certain angle value on the surface of the pitch scale 2010.

This prevents the dual-medium nozzle 19 from shaking or shifting during the test, ensuring the reliability of the test data.

[0028] Based on the above, the specific working steps of this utility model include: Step S1: Open the main chamber door 2 of the main chamber, connect the external equipment providing compressed air to the air source interface 16 of the compressed air pipeline, confirm that the ball valve 1 is in the closed state, then inject the test liquid into the storage tank 7 through the external water source interface, confirm that the filter element is installed in the filter 10, open the rear door 4 of the spray chamber, flip open the atomizing body 6 of the atomizing chamber, clamp the dual-media nozzle 19 onto the fastening seat 2012 of the adjustable nozzle base 20 with bolts, loosen the yaw angle adjustment knob 2005 and rotate the yaw angle adjustment screw 2002 so that the yaw angle mark 2003 is adjusted. Point to a certain angle value on the surface of the angle scale 2004, tighten the yaw angle adjustment knob 2005 to complete the angle adjustment of the dual-medium nozzle 19 in the horizontal direction, loosen the pitch angle adjustment knob 2009 and then rotate the pitch angle adjustment nut 2007 so that the pitch angle adjustment nut 2007 is rotated to a certain angle value on the surface of the pitch scale 2010, tighten the pitch angle adjustment knob 2009 to complete the angle adjustment of the dual-medium nozzle 19 in the vertical direction, and finally align the mist outlet of the dual-medium nozzle 19 with the atomizing chamber at the media nozzle in a suitable orientation; Step S2: Compressed air is introduced into the compressed air pipeline. According to the test requirements, the air pressure is adjusted by the pressure regulating valve 17 to form compressed air. The value of the air pressure gauge 18 is observed to ensure that the pressure of the compressed air meets the atomization requirements. Then, the ball valve I9 ​​is ​​opened to introduce the test liquid into the storage pipeline. The feed pump 11 is started. The values ​​of the flow meter 12 and the liquid pressure gauge 13 are observed. The feed pump 11 is adjusted to ensure that the flow rate and pressure of the test liquid are within a suitable range. The compressed air and the test liquid are transported to the dual-medium nozzle 19 through the pipeline. The mist outlet of the dual-medium nozzle 19 sprays the test liquid, which has been atomized by the compressed air, towards the opened atomization chamber. Step S3: Observe the atomization state of the test liquid after it is atomized by compressed air. Based on the observed atomization state, readjust the pressure regulating valve 17 and the feed pump 11 to make the atomization state of the test liquid meet the predetermined requirements. Record the flow rate value on the flow meter 12 and the pressure values ​​on the air pressure gauge 18 and the liquid pressure gauge 13 at this time. Then, close the ball valve I9 ​​to cut off the test liquid entering the storage pipeline, turn off the external equipment that provides compressed air to stop the delivery of compressed air, and then open the ball valve II 14 and the overflow valve 15 to release the pressure in the storage pipeline. Finally, open the outlet 8 at the bottom of the storage tank 7 to discharge the test liquid in the storage tank 7, thus completing the verification process.

[0029] Remove the dual-medium nozzle 19 and install it on the corresponding fragrance equipment. Adjust the nozzle angle, gas pressure, and liquid pressure according to the optimal parameters obtained in the verification process, namely yaw angle, pitch angle, flow rate, and pressure values ​​on the air pressure gauge 18 and liquid pressure gauge 13, so as to avoid product quality problems caused by poor atomization effect of the dual-medium nozzle 19.
