Description

Technical Field

[0001] The present invention relates to the technical field of cigarette making machines, and particularly to a cooling system for a cigarette making machine. Background Art

[0002] Vortex tube refrigeration is a non-electric refrigeration technology, which can separate compressed air into cold-end air and hot-end air. Its refrigeration capacity is determined by the pressure and flow rate of the compressed air. Compressed air is required in the production process of a cigarette factory, such as in the filter rod emission room. Therefore, a cooling measure for the wrapping and packaging unit using vortex tube refrigeration can be directly constructed with compressed air as the raw material. After the cold air cools the motor, its temperature rises. If it is directly discharged into the workshop, it is very likely to cause the temperature in the workshop to rise. According to the cigarette production process, the temperature in the workshop needs to be maintained within a set temperature and humidity range. Therefore, the air conditioner needs to be turned on throughout the year to control the temperature of the wrapping and packaging workshop.

It should be understood that the data used in this way can be interchanged under appropriate circumstances, so that the embodiments of the present invention described here can be implemented in an order other than those illustrated or described here. In addition, the terms "comprising" and "having" and any variations thereof are intended to cover non-exclusive inclusion.

[0040] Figure 1 is a structural connection diagram of a cigarette making machine cooling system provided according to an embodiment of the present invention. As Figure 1 shown, the cigarette making machine cooling system includes: a vortex tube 1, a cigarette making unit 2 and a heat exchanger 3;

[0041] The vortex tube 1 includes a first air inlet a and a cold end outlet b; the first air inlet a is communicated with a compressed air pipeline 4 for receiving the air in the compressed air pipeline 4; the cold end outlet b is communicated with the cigarette making unit 2 for inputting the output first air into the cigarette making unit 2; the cigarette making unit 2 is communicated with the heat exchanger 3 for inputting the output second air into the heat exchanger 3 for heat exchange; the heat exchanger 3 is also communicated with a workshop 5 for discharging the output third air to the workshop 5;

[0042] Among them, the temperature of the first air is lower than the temperature of the second air; the temperature of the third air is lower than the temperature of the second air.

[0043] Among them, the refrigeration of the vortex tube 1 is a non-electric refrigeration technology, and the vortex tube 1 can separate compressed air into cold end air and hot end air. In the prior art, the temperature of the cold end air output by the vortex tube 1 can reach -40°C to 20°C, and the temperature of the hot end air can reach 100°C, and its refrigeration capacity is determined by the compressed air pressure and flow rate. In the embodiment of the present invention, the first air inlet a of the vortex tube 1 is communicated with the compressed air pipeline 4, and the compressed air pipeline 4 can input compressed air into the vortex tube 1. The compressed air is converted into the first air under the action of the vortex tube 1. The temperature of the first air is lower than the temperature of the compressed air, and the first air is input into the cigarette making unit 2 from the cold end outlet b.

[0044] Among them, since the cigarette making unit 2 needs to use compressed air during the working process, in the embodiment of the present invention, compressed air is directly used as the raw material, and the vortex tube 1 is used to cool the first air and input it into the cigarette making unit 2 for cooling.

[0045] Among them, after the first air enters the cigarette making unit 2 for cooling, it is heat-exchanged into the second air. In some embodiments, the cigarette making unit 2 includes a motor cabinet 21 and a cooling exhaust fan 22; the cold end outlet b is communicated with the motor cabinet 21; the cooling exhaust fan 22 is communicated with the heat exchanger 3. The first air enters the motor cabinet 21 for heat exchange and then outputs the second air through the cooling exhaust fan 22. The temperature of the second air is higher than that of the first air. Since the temperature of the second air is high, if it is directly discharged into the workshop 5, it will cause the temperature of the workshop 5 to rise. Therefore, a heat exchanger 3 is provided, the cigarette making unit 2 is communicated with the heat exchanger 3, the second air is input into the heat exchanger 3 for heat exchange, and the heat-exchanged third air is discharged into the workshop 5, transferring the heat in the cigarette making unit 2 to the heat exchanger 3, reducing the energy consumption of the air conditioner in the workshop 5, and realizing the reduction of the energy consumption and the stability of the temperature in the workshop 5.

[0046] Among them, the heat exchanger 3 can be a solid-phase heat storage medium, and the solid-phase heat storage medium has a higher waste heat recovery efficiency for high-temperature air, such as materials like paraffin.

[0047] Specifically, the cigarette making unit 2 includes multiple cigarette packing machines. The cigarette packing machines require high-power motors to drive the operation of the equipment. Each cigarette packing machine has 2 to 3 motors for power output, and a large amount of heat will be generated during actual operation. At present, the air temperature at the air-cooled exhaust outlet configured for the cigarette packing machine can be as high as 45°C, and the hot air is directly discharged into the workshop 5. Therefore, it is easy to cause the temperature of the cigarette packing workshop 5 to rise rapidly. In order to ensure the temperature and humidity balance of the cigarette packing workshop 5, the air conditioner needs to perform cooling operations, which will lead to an increase in the energy consumption of the air conditioning system. Therefore, in the embodiments of the present invention, a cigarette machine cooling system with both cooling and heat storage functions is provided. The hot air exhausted from the cigarette packing machine after being cooled by using the low-temperature cold air generated by the vortex tube 1 enters the heat storage medium for waste heat recovery, and the temperature of the air after being absorbed by the heat storage medium can be controlled to be close to the temperature of the workshop 5, and then it can be directly discharged to the workshop 5 without affecting the temperature change of the workshop 5.

[0048] It can be understood that compressed air is also required in the cigarette making unit 2 of the prior art. In the embodiments of the present invention, the low-temperature air generated by the combination of the vortex tube 1 naturally has the ability to cool the heat source, maintaining the temperature of the workshop 5 without increasing other energy consumption, reducing the long-term operation cost, and at the same time reducing the impact on the environment.

[0049] The technical solution of the embodiments of the present invention absorbs the heat during the operation of the cigarette making unit by using a heat exchanger, and no longer directly discharges the heat to the workshop; at the same time, to ensure the working temperature of the cigarette making unit, a vortex tube is introduced to generate strong cold air for cooling. By introducing the cold and hot air of the vortex tube, the heat of the cigarette packing unit is efficiently transferred to the heat exchanger, maintaining the temperature of the cigarette making unit to match the process requirements of the workshop, thereby reducing the energy consumption of air conditioning temperature control and realizing the reduction of the energy consumption and the stability of the temperature in the cigarette packing workshop.

[0050] Optionally, continue to refer to Figure 1 As shown, the vortex tube 1 further includes a hot end outlet c;

[0051] The hot end outlet c is communicated with the heat exchanger 3 for inputting the output fourth air into the heat exchanger 3 for heat exchange;

[0052] Wherein, the temperature of the fourth air is greater than the temperature of the first air.

[0053] Wherein, the hot end outlet c can be used to output the hot end air generated by the vortex tube 1, that is, the fourth air, and the temperature of the fourth air is greater than the temperature of the first air.

[0054] Wherein, the hot end outlet c is also communicated with the heat exchanger 3, so that the fourth air can be input from the hot end outlet c into the heat exchanger 3, preventing the fourth air from flowing into the workshop 5 and causing the temperature of the workshop 5 to rise.

[0055] It can be understood that the technical solution of the embodiment of the present invention makes full use of the heat exchanger 3 to absorb the heat of the second air after heat exchange and the fourth air output by the vortex tube 1, so that the air in the workshop 5 will not affect the temperature of the workshop 5, thereby reducing the energy consumption of the air conditioning system caused by directly discharging the air carrying heat into the vehicle frame.

[0056] The technical solution of the embodiment of the present invention, by communicating the hot end outlet of the vortex tube with the heat exchanger, makes full use of the heat of the second air after heat exchange and the fourth air output by the vortex tube, so that the air in the workshop will not affect the workshop temperature, thereby reducing the energy consumption of the air conditioning system.

[0057] Optionally, continue to refer to Figure 1 As shown, it further includes a first air temperature regulating tank 6;

[0058] The first air temperature regulating tank 6 includes a first regulating inlet d, a second regulating inlet e and a first regulating outlet f; the first regulating inlet d is communicated with the hot end outlet c, the second regulating inlet e is communicated with the cigarette making unit 2, and the first regulating outlet f is communicated with the heat exchanger 3;

[0059] The first air temperature regulating tank 6 is used for receiving the second air and the fourth air and mixing the second air and the fourth air and then outputting them to the heat exchanger 3.

[0060] Wherein, the first air temperature regulating tank 6 can play a role in air mixing. In some embodiments, the outer wall of the first air temperature regulating tank 6 may include heat insulating materials and a pressure sensor is also provided inside. The first regulating inlet d of the first air temperature regulating tank 6 is communicated with the hot end outlet c, and can receive the fourth air from the hot end outlet c of the vortex tube 1. At the same time, the second regulating inlet e is communicated with the cigarette making unit 2 to receive the second air after heat exchange from the cigarette making unit 2. The first air temperature regulating tank 6 can mix the fourth air and the second air and then output them to the heat exchanger 3.

[0061] Since the outlet temperature of the cigarette-making unit 2 is about 40-50°C, it is difficult to be directly adsorbed as low-grade heat energy. However, the temperature of the hot air generated by the vortex tube 1 can reach up to 100°C. After the two are mixed, the temperature of the heat-dissipating air can be increased, making the heat carried by it more convenient to be absorbed by the heat exchanger 3, enhancing the ability of the waste heat in the mixed air to be efficiently absorbed by the energy storage medium, and effectively recovering the cooled heat on the premise of realizing low-temperature air refrigeration.

[0062] The technical solution of the embodiment of the present invention, by using the mixing of the fourth air of the vortex tube and the second air of the cigarette-making unit, increases the probability of the waste heat being absorbed by the heat exchanger, thereby enhancing the combined efficiency of the overall system for refrigeration and temperature control. At the same time, the heat absorbed by the heat exchanger can be used for other production links in the cigarette factory that require low-grade heat, such as heating water or meeting the heat demand for office work.

[0063] Optionally, Figure 2 is a schematic diagram of the module connection of a cigarette-making machine cooling system provided according to an embodiment of the present invention. As shown in combination with Figure 1 and Figure 2 shown, it further includes a first valve 7 and a control unit 8;

[0064] The first valve 7 is arranged between the first air temperature regulating tank 6 and the heat exchanger 3;

[0065] The control unit 8 is respectively communicatively connected to the first air temperature regulating tank 6 and the first valve 7, and is used to adjust the pressure of the first air temperature regulating tank 6 and the working state of the first valve 7.

[0066] Among them, the working state of the first valve 7 may include the opening and closing state of the first valve 7, as well as the opening degree state. The control unit 8 can adjust the air flow rate entering the heat exchanger 3 by controlling the working state of the first valve 7.

[0067] Among them, both the pressure and temperature of the first air temperature regulating tank 6 affect the temperature of the mixed fourth air and second air. Therefore, the control unit 8 is also communicatively connected to the first air temperature regulating tank 6 to adjust the pressure of the first air temperature regulating tank 6.

[0068] Exemplarily, paraffin is used as the heat exchange medium of the heat exchanger 3, and the paraffin is loaded inside the heat exchanger 3 in the form of a porous medium or a capsule. The first air temperature regulating tank 6 inputs the mixed second air and fourth air into the heat exchanger 3, and the hot air flows through the outside of the paraffin. The paraffin, as the heat storage medium, can absorb the heat carried by the hot air. In some embodiments, the heat exchanger 3 is provided with a replaceable device. When the total air flow rate of the paraffin-treated air exceeds 90% of the treatable flow rate, the control unit 8 issues a reminder to manually replace the paraffin heat storage medium, so as to absorb all the heat generated by the cigarette making and packing unit into the solid heat storage medium, avoiding its direct discharge into the workshop 5 and causing the temperature of the workshop 5 to rise; wherein, the total treatable hot air flow rate m f of the paraffin, the gas temperature T p in the first air temperature regulating tank 6, the corresponding specific enthalpy h p and the heat absorption Q s during the phase change of the paraffin satisfy m f =Q s / h p . Therefore, the control unit 8 can control the opening degree of the first valve 7 according to the gas temperature T p in the first air temperature regulating tank 6 and the heat absorption Q s during the phase change of the paraffin, and further control the hot air flow rate m f .

[0069] In some embodiments, a second valve 9 is further included; the second valve 9 is arranged between the workshop 5 and the heat exchanger 3; the control unit 8 is also communicatively connected to the second valve 9 for controlling the working state of the second valve 9. Among them, the working state of the second valve 9 may include the opening and closing state of the second valve 9 and the opening degree state. The control unit 8 can adjust the air flow rate entering the workshop 5 by controlling the working state of the second valve 9, and further control the temperature of the workshop 5. The control unit 8 can jointly control the first valve 7 and the second valve 9, so that the air temperature output by the heat exchanger 3 is close to the temperature of the workshop 5, and further maintain the stability of the temperature of the workshop 5.

[0070] The technical solution of the embodiment of the present invention, by setting the first valve and the control unit, and the control unit is communicatively connected to the first air temperature regulating tank and the first valve respectively, enables the control unit to adjust the pressure of the first air temperature regulating tank and the working state of the first valve, and jointly with the second valve to make the temperature of the third air finally discharged into the workshop close to the temperature of the workshop 5, ensuring the stability of the workshop temperature and reducing the energy consumption.

[0071] Optionally, as shown in Figure 1 and Figure 2 , a fan unit 10, a second air temperature regulating tank 11 and a control unit 8 are further included;

[0072] The second air temperature regulating tank 11 includes a third regulating inlet g, a fourth regulating inlet h, and a second regulating outlet i; the third regulating inlet g is communicated with the cold end outlet b; the fourth regulating inlet h is communicated with the fan unit 10; the second regulating outlet i is communicated with the cigarette making unit 2;

[0073] The second air temperature regulating tank 11 is used for receiving the first air and the fifth air input by the fan unit 10, mixing the first air and the fifth air, and then outputting the mixture to the cigarette making unit 2;

[0074] The control unit 8 is communicatively connected with the fan unit 10 and is used for controlling the working state of the fan unit 10 to control the flow rate of the fifth air.

[0075] Wherein, the fourth regulating inlet h is communicated with the fan unit 10, and the fan unit 10 can absorb the air in the workshop 5 into the second air temperature regulating tank 11. The third regulating inlet g is communicated with the cold end outlet b, so that the first air and the fifth air input by the fan unit 10 are both input into the second air temperature regulating tank 11 for mixing, meeting the air flow rate requirement when cooling the motor, and at the same time forming a mixture of high and low temperature air.

[0076] Wherein, the control unit 8 can control the size of the air flow rate extracted from the workshop 5, that is, the flow rate of the fifth air, by communicatively connecting with the fan unit 10, and further can control the temperature of the air output by the second air temperature regulating tank 11.

[0077] In the technical solution of the embodiment of the present invention, by arranging a fan unit in the workshop, the control unit can control the working state of the fan unit, and further control the flow rate of the fifth air entering the second air temperature regulating tank. On the one hand, the fan unit can further reduce the temperature of the workshop 5. On the other hand, it can also be mixed with the first air and input into the cigarette making unit to increase the air flow rate in the pit and strengthen the convective heat transfer to achieve temperature reduction.

[0078] Optionally, as shown in Figure 1 and Figure 2 it further includes a temperature sensor 12, a third valve 13, and a fourth valve 14;

[0079] The temperature sensor 12 is arranged between the second regulating outlet i and the cigarette making unit 2; the third valve 13 is arranged between the second regulating outlet i and the cigarette making unit 2; the fourth valve 14 is arranged between the first air inlet a and the compressed air pipeline 4;

[0080] The control unit 8 is communicatively connected with the temperature sensor 12, the third valve 13, and the fourth valve 14 respectively, and is used for receiving the temperature signal of the temperature sensor 12 and controlling the working states of the fan unit 10, the third valve 13, and the fourth valve 14 according to the temperature signal.

[0081] Among them, the temperature sensor 12 can be used to measure the temperature of the air entering the cigarette making unit 2. Since the air temperature entering the cigarette making unit 2 directly affects the cooling effect of the cigarette making unit 2, the temperature sensor 12 and the control unit 8 are set. The control unit 8 receives the temperature signal of the temperature sensor 12 in real time, and then monitors the cooling of the cigarette making unit 2 in real time.

[0082] Among them, the third valve 13 can determine the air flow rate entering the cigarette making unit 2, and both the air flow rate and the temperature can affect the cooling effect of the cigarette making unit 2. The fourth valve 14 can determine the compressed air flow rate entering the vortex tube 1, and then determine the flow rate of the first air. Generally, before the cigarette making unit 2 operates, the compressed air, the fourth valve 14 and the vortex tube 1 are turned on in advance to generate cold and hot air and store them in the first air temperature regulating tank 6 and the second air temperature regulating tank 11. When the cigarette making unit 2 operates, the third valve 13 is opened to release cold air into the cigarette making unit 2 for cooling. The opening degree of the third valve 13 is controlled by the control unit 8 to make the temperature of the cigarette making unit 2 close to the temperature of the workshop 5.

[0083] Specifically, the opening degree of the third valve 13 is related to the operating speed of the cigarette making unit 2. In actual operation, the inside of the cigarette making unit 2 operates under negative pressure, and a small amount of air from the workshop 5 will be sucked into the cigarette making unit 2 to prevent the leakage of low-temperature cold air into the workshop 5. The rotational speed of the fan unit 10 and the opening degree of the third valve 13 are both positively correlated with the working state of the cigarette making unit 2. At the same time, the rotational speed of the fan unit 10 also affects the opening degree of the third valve 13. When the cooling effect cannot reach the required temperature of the cigarette making unit 2, the feedback increases the opening degree of the third valve 13 to supply more cold air, and at the same time controls the rotational speed of the fan unit 10 to increase accordingly, so as to increase the cold air flow rate and strengthen the convective heat transfer to achieve cooling. Assume that the set temperature of the second air temperature regulating tank 11 is defined as T e , and through mixing the first air and the fifth air, T e is adjusted. The second air temperature regulating tank 11 has two functions: one is to adjust the temperature as needed; if the moisture content of the mixed air is ω e when the corresponding temperature is T e , then the corresponding air specific enthalpy value h e can be calculated as:

[0084] h e =(1.006*T e )+ω e (2501 + 1.86*T e );

[0085] The second is to store gas: It is set according to the motor configuration of the cigarette making unit 2 and the flow rate of the fan unit 10. Assume that the heat generated by the motor of the cigarette making unit 2 is Q e , and the rated flow rate of the fan unit 10 is m, then there is Q e =m*he , the temperature T for regulating the air temperature under rated conditions can be obtained e , and this value can be set according to the actual situation. For example, when a greater refrigerating capacity is required, Te is reduced. The adjustment of Te can be achieved by jointly adjusting the rotational speed of the fan unit 10 and the first air flow generated by the vortex tube 1.

[0086] In some embodiments, a water collector 16 is further included; the second air temperature regulating tank 11 further includes a third regulating outlet; the third regulating outlet is communicated with the water collector 16 and is used for inputting the output condensed water into the water collector 16. Among them, since the temperature difference between the first air and the fifth air is relatively large, the condensed water caused by the cooling of the fifth air flows into the water collector 16 for storage.

[0087] Exemplarily, the adjustment process of the cigarette making machine cooling system can be as follows:

[0088] After the cigarette making unit 2 operates, the control unit 8 receives the temperature signal in real time. When the temperature signal is greater than the preset temperature, the fourth valve 14 is controlled to open, the vortex tube 1 is controlled to open, and the fan unit 10 is controlled to open, so that the first air temperature regulating tank 6 and the second air temperature regulating tank 11 store hot and cold air. When the temperature signal is less than or equal to the preset temperature, the third valve 13 is controlled to open, so that the second air enters the cigarette making unit 2 for cooling. After the cigarette making unit 2 is cooled, the heat-exchanged second air is input into the second air temperature regulating tank 11, and after the second air and the fourth air are mixed, they are input into the heat exchanger 3 for heat exchange. When the temperature of the heat-exchanged third air is close to the temperature of the workshop 5, the third air is discharged into the workshop 5.

[0089] The technical solution of the embodiment of the present invention realizes the efficient transfer of the heat of the cigarette packing unit to the heat exchanger 3 by introducing the hot and cold air of the vortex tube 1, realizes the long-term maintenance of the temperature of the cigarette packing unit to match the process requirements of the workshop 5, and further reduces the energy consumption of air-conditioning temperature control, and realizes the reduction of the energy consumption and the stability of the temperature in the cigarette packing workshop 5.

[0090] Optionally, continue to refer to Figure 2 as shown, an interaction unit 15 is further included;

[0091] The control unit 8 is also communicatively connected to the interaction unit 15 and is used for outputting real-time temperature information, the working state of the fan unit 10, and the working states of the third valve 13 and the fourth valve 14 according to the temperature signal.

[0092] Among them, the interaction unit 15 can perform human-computer interaction. The control unit 8 inputs the real-time temperature information, the working state of the fan unit 10, and the working states of the third valve 13 and the fourth valve 14 into the interaction unit 15, so that the operator can view the real-time temperature information, the working state of the fan unit 10, and the working states of the third valve 13 and the fourth valve 14 in real time, facilitating the operator's management. The operator can also input a regulation signal to the control unit 8 through the interaction unit 15 to regulate the valve opening, the rotation speed of the fan unit 10, and the pressures of the first air temperature regulating tank 6 and the second air temperature regulating tank 11.
