Description

Technical Field

[0001] The present invention belongs to the technical field of cigarette manufacturing, and in particular relates to a liquid atomizing device. Background Art

[0002] The silk-making workshop is an assembly line processing unit, and its main production process includes unpacking, slicing, loosening and rehydrating, moistening and adding materials, shredding, drying, blending and adding flavoring, etc. Among them, the leaf moistening and adding materials process is to atomize the liquid with a certain temperature and spray it on the surface of the tobacco leaves through a dual-media nozzle, which improves the taste and increases the moisture content and temperature of the tobacco leaves.

[0003] At present, most silk-making workshops use steam as a medium to atomize the liquid feed. The reason is that the liquid feed used is all sugar, which will become viscous at room temperature, resulting in poor atomization effect. However, the essence used in the subsequent blending and flavoring process can still maintain the fluidity of the liquid at room temperature. This is the origin of the saying "hot feeding, cold flavoring". Since the factory uses centralized steam supply, after long-distance transportation, pipeline insulation, steam drainage and other problems, the steam used at the end of the steam network is saturated steam rather than supersaturated steam. Its dryness is low and the steam quality is poor. It contains a certain amount of water vapor. When using such steam to atomize the liquid feed, the water vapor in it is also brought to the surface of the material. Let the mass of this part of water vapor be G 杂 , the mass of solute raw sugar is G 糖 , the mass of solvent water is G 水 , the total mass of the batch material is G 总 The calculation formula for the overall feeding ratio K is: , where G 总 =The sum of the raw sugar mass, solvent water mass, and tobacco leaf mass. It can be seen that the water vapor contained in the steam will reduce the overall feeding ratio in the feeding process, thereby affecting the intrinsic quality of the tobacco leaves.

[0004] As mentioned above, the overall feeding ratio of the current processing atomization method is greatly affected by the steam quality, especially in small batches (G 总 The impact is greater when processing key brands (hours); the current processing atomization method cannot guarantee the accuracy of the overall feeding ratio.

[0020] The following description of at least one exemplary embodiment is merely illustrative in nature and is in no way intended to limit the present disclosure, its application, or uses.

[0021] Technologies, methods, and equipment known to ordinary technicians in the relevant art may not be discussed in detail, but where appropriate, the technologies, methods, and equipment should be considered part of the specification.

[0022] In all examples shown and discussed herein, any specific values ​​should be interpreted as merely exemplary and not limiting. Therefore, other examples of the exemplary embodiments may have different values.

[0023] like Figure 1 、 Figure 2 、 Figure 3 As shown, the liquid atomizing device includes: a cold compressed air heating steel pipe 8 spirally wound on a steam pipe 2, a glass fiber insulation material 9, a heat insulation cover shell 1, a pneumatic diaphragm valve 6, a PLC controller, a temperature sensor, a cold compressed air supply device, and a dual-medium nozzle;

[0024] The inlet 3 of the cold air compressed gas heating steel pipe is connected to the cold air compressed gas supply device, and the outlet 4 of the cold air compressed gas heating steel pipe is connected to the dual-medium nozzle pre-filled with liquid through a hot air compressed gas circulation pipeline, and the hot air compressed gas circulation pipeline is provided with an air compressed gas stop valve;

[0025] The heat-insulating cover shell completely wraps the cold air heating steel pipe, the space between the heat-insulating cover shell and the cold air heating steel pipe is filled with the glass fiber heat-insulating material, and the inlet and outlet of the cold air heating steel pipe both extend from the heat-insulating cover shell;

[0026] The temperature sensor is arranged at the outlet of the cold air heating steel pipe, and the temperature sensor is electrically connected to the PLC controller;

[0027] The pneumatic film valve for controlling the steam flow is electrically connected to the PLC controller.

[0028] In some embodiments, the cold air compressed gas heating steel pipe is a stainless steel pipe.

[0029] In some embodiments, the insulation cover shell includes a first shell 11 and a second shell 10, the first shell is provided with an inlet avoidance hole for avoiding the inlet of the cold air heating steel pipe, and the second shell is provided with an outlet avoidance hole for avoiding the outlet of the cold air heating steel pipe; the first shell and the second shell are fixedly connected by lugs and bolts to form the insulation shell.

[0030] In some embodiments, the PLC controller is a Siemens PLC controller.

[0031] In some embodiments, the pneumatic diaphragm valve is a pneumatic diaphragm valve of model MK78 with a diameter of D20.

[0032] In some embodiments, the bolt is made of stainless steel.

[0033] like Figure 2 As shown, the steam pipe is made of stainless steel and has a diameter of 150 mm.

[0034] The main steam stop valve 5 is always open, so close the condensate discharge valve 7 first.

[0035] Set the preset value of hot air compressor on the host computer, refer to the barrel temperature value, and the barrel temperature value is equal to the preset value of hot air compressor.

[0036] The dual-medium nozzle is pre-filled with heated liquid. It is assumed that the temperature of the heated liquid can be maintained for a period of time.

[0037] The cold compressed air heats the steel pipe due to the heat of the steam, which in turn heats the cold compressed air. The PLC controller uses a temperature sensor to detect whether the temperature of the hot compressed air has reached a preset value. If so, it controls the opening of the pneumatic diaphragm valve to a specific value, maintaining the hot compressed air temperature equal to that of the feed liquid. The compressed air shut-off valve is opened, and the hot compressed air flows through the hot compressed air flow pipe to the outlet of the dual-medium nozzle, atomizing the feed liquid sprayed from the dual-medium nozzle outlet.

[0038] The condensate drain valve 7 is opened to drain the condensed water, and after draining, the condensate drain valve is closed.

[0039] Please note that the temperature of the liquid feed and the hot air compressor must be the same to ensure the fluidity of the liquid feed. If they are different, if the temperature of the hot air compressor is lower than that of the liquid feed, then the temperature of the liquid feed will also decrease, resulting in a decrease in the fluidity of the liquid feed.

[0040] The liquid atomizing device can ensure the accuracy of the overall feeding ratio.

[0041] When changing brands and needing to lower the barrel temperature, that is, lowering the temperature of the hot compressed air, the PLC controller controls the pneumatic diaphragm valve to close, without heating, and only quickly cools down by blowing compressed air, and then reheats.

[0042] like Figure 4 As shown, the present disclosure also provides a liquid atomization method, which is implemented by using the above-mentioned liquid atomization device, and the method includes: step 110, setting a preset value of hot compressed air based on the barrel temperature, wherein the barrel temperature is equal to the preset value of hot compressed air; step 120, pre-filling the heated liquid into the dual-medium nozzle; step 130, collecting the real-time temperature of the hot compressed air by means of a temperature sensor; step 140, judging whether the real-time temperature of the hot compressed air is equal to the preset value of the hot compressed air; step 150, if the real-time temperature of the hot compressed air is equal to the preset value of the hot compressed air, controlling the opening of the pneumatic diaphragm valve to decrease so as to keep the real-time temperature equal to the preset value of the hot compressed air; step 160, opening the compressed air stop valve, so that the hot compressed air that meets the requirements passes through the hot compressed air flow pipe and flows into the dual-medium nozzle pre-filled with liquid, thereby realizing the atomization of the liquid by using the hot compressed air.

[0043] This method uses hot compressed air instead of steam, and uses the hot compressed air to atomize the liquid feed sprayed from the nozzle outlet at the nozzle outlet, thereby optimizing the atomization method of the liquid feed. The use of hot compressed air (without water vapor) makes the quality of the tobacco leaves more stable, thereby ensuring the accuracy of the overall feeding ratio, thereby improving the processing effect of the feeding process.
