Description

TECHNICAL FIELD

[0001] The utility model relates to water tank equipment technical field, especially a kind of heating water tank. BACKGROUND

[0002] In tobacco primary processing, to improve the moisture in tobacco stem, usually atomize tobacco stem by using feeder. The feeder generally includes at least one heating water tank, water pump and multiple nozzles. The heating water tank is provided with a water supplement port, a water outlet and a steam inlet. Steam is introduced into the heating water tank to directly contact with water to raise the temperature of water to a set temperature. The water at the set temperature is then delivered to the nozzles through the water outlet and the water pump and sprayed through the nozzles to atomize the tobacco stem. The heating water tank is further provided with a liquid level sensor and a temperature sensor to detect the water level and temperature in the water tank.

[0003] However, the existing heating water tank often has inaccurate detection results of the temperature sensor and the liquid level sensor and water pollution in the water tank, which can cause unqualified tobacco and reduce product quality. SUMMARY

[0004] The utility model discloses a heating water tank, which can avoid sensor misjudgment, prevent water pollution and improve tobacco quality.

[0005] To solve the above technical problems, the applicant has found that the reason why the existing heating water tank is prone to sensor misjudgment and causes the quality of tobacco to decrease is that the temperature sensor and the liquid level sensor in the existing heating water tank are arranged in the same area as the water supplement port. When water is added to the heating water tank or pumped by the water pump, the water fluctuates, which can cause the liquid level sensor to misjudge and the temperature sensor to misjudge due to direct contact with normal temperature water when water is added. As a result, the amount of added water and the water temperature do not meet the process requirements, which reduces product quality. The applicant has also found that the reason why the existing heating water tank is prone to water pollution and causes the quality of tobacco to decrease is that the existing heating water tank uses a direct contact heating method for steam and water. When the steam pipeline is corroded, the steam can carry rust or dirt, which directly mixes with water to pollute the water in the water tank, thereby causing turbid water. If the turbid water enters production, a large amount of unqualified tobacco can be produced, which reduces product quality.

[0006] The embodiment of the utility model discloses a heating water tank, which comprises a partition plate. The partition plate divides the space inside the heating water tank into a water supplement area, a heating area and a measurement area. The bottoms of the water supplement area, the heating area and the measurement area are connected to each other. The heating water tank further comprises:

[0007] A water inlet is arranged on the side wall of the water tank in the water supplement area. Water can enter the water supplement area through the water inlet.

[0008] a steam inlet and a condensed water outlet, the steam inlet and the condensed water outlet being respectively arranged on the side wall of the water tank in the heating area;

[0009] a heating coil arranged in the heating area, one end of the heating coil being connected with the steam source through the steam inlet, and the other end of the heating coil being connected with the condensed water outlet, the heating coil being used for heating the water in the water tank;

[0010] a first liquid level sensor arranged in the measuring area, the first liquid level sensor being used for detecting whether the height of the water in the water tank reaches a first preset height;

[0011] a second liquid level sensor arranged in the measuring area and below the first liquid level sensor, the second liquid level sensor being used for detecting whether the water in the water tank reaches a second preset height;

[0012] a temperature sensor arranged in the measuring area, the temperature sensor being used for collecting whether the temperature of the water in the measuring area reaches a preset temperature;

[0013] a water outlet arranged on the side wall of the water tank in the measuring area, the water in the measuring area being discharged through the water outlet.

[0014] By separating the water tank into the water supplementing area, the heating area and the measuring area, arranging the water inlet and the water outlet in the water supplementing area, and arranging the liquid level sensor and the temperature sensor in the measuring area, the sensor is separated from the water inlet and the water outlet, so that the liquid level sensor is not inaccurate due to water level fluctuation when the water tank is filled with water or the water pump is pumping, and the temperature sensor is not inaccurate due to direct contact between normal temperature water and the temperature sensor when the water tank is filled with water, so that the tobacco quality can be improved. Meanwhile, the water in the water tank is heated by heat release of the heating coil, so that the steam is not directly contacted with the water in the water tank, and thus the rust or dirt in the steam is prevented from entering the water body to pollute the water body, and the tobacco quality is further improved.

[0015] Optionally, the height of the water outlet is equal to the height of the temperature sensor.

[0016] Optionally, the heating water tank further comprises a water outlet pipe, one end of the water outlet pipe being connected with the water outlet, and the other end of the water outlet pipe being connected with a water using component, the height of the water using component being higher than the height of the heating water tank, a water pump being arranged on the water outlet pipe, the water pump being used for conveying the water in the heating water tank to the water using component.

[0017] Optionally, the heating water tank further comprises a backwater outlet arranged on the side wall of the water tank in the heating area, the backwater outlet being connected with the lower end of the water using component through a backflow pipe, when the water pump stops running, the water in the water using component can flow back to the water tank through the backflow pipe and the backwater outlet under the action of gravity.

[0018] Optionally, along the height direction of the water tank, the backwater outlet is higher than the highest part of the heating coil, and along the horizontal direction, the backwater outlet is located between the steam inlet and the condensed water outlet.

[0019] Optionally, the heating water tank further comprises an overflow outlet, which is arranged on the side wall of the water tank in the water supplement area, and the height of the overflow outlet is higher than the height of the first liquid level sensor and lower than the height of the backwater outlet, so that when the height of the water in the water tank exceeds the first preset height, the water in the water tank can overflow from the overflow outlet.

[0034] In order to make the purpose, technical scheme and advantages of the present application more clear, the embodiments of the present application will be further described in detail in combination with the drawings.

[0035] In tobacco processing, a feeder is typically used to atomize the tobacco stems to increase their moisture content. This feeder generally includes at least a heating water tank, a water pump, and multiple nozzles. The heating water tank has a water inlet, an outlet, and a steam inlet. By introducing steam into the heating water tank, the steam comes into direct contact with the water, raising the water temperature to a set level. The water, now at the set temperature, is then pumped through the outlet and the water pump to the nozzles, where it is sprayed out to atomize the tobacco stems. The heating water tank also contains level and temperature sensors to monitor the water level and temperature.

[0036] However, existing heating water tanks often suffer from inaccurate temperature and level sensor readings, as well as water contamination within the tank. These issues can lead to the production of substandard tobacco and reduce product quality.

[0037] To address the aforementioned technical issues, the applicant discovered that the existing heating water tanks are prone to sensor misreading, leading to a decline in tobacco quality. This is because the temperature and level sensors in the existing tanks are located in the same area as the water inlet. When water is added or pumped in, fluctuations in the water level cause misreading by the level sensor. Additionally, direct contact between room-temperature water and the temperature sensor during water addition can also cause misreading, resulting in the water volume and temperature not meeting process requirements and thus reducing product quality. The applicant also found that the existing heating water tanks are prone to water contamination, further contributing to a decline in tobacco quality. This is because the existing heating water tanks use direct contact heating between steam and water. When the steam pipes corrode, the steam carries rust or dirt, which mixes directly with the water, contaminating the tank water and causing turbidity. If this turbid water enters production, it will produce a large amount of substandard tobacco, reducing product quality.

[0038] like Figures 1 to 4 As shown, this utility model discloses a heating water tank, including a partition 1. The partition 1 divides the internal space of the heating water tank into a water replenishment area 2, a heating area 3, and a measuring area 4. The bottoms of the water replenishment area 2, the heating area 3, and the measuring area 4 are interconnected. Specifically, the partition 1 includes a first plate 110, a second plate 120, and a third plate 130 connected to each other. The first plate 110, the second plate 120, and the third plate 130 have the same height and the same distance from the bottom of the water tank, thereby ensuring that the water levels in the water replenishment area 2, the heating area 3, and the measuring area 4 are consistent.

[0039] The heating water tank further comprises a water inlet 5, a steam inlet 6, a condensed water outlet 7, a heating coil 8, a first liquid level sensor 9, a second liquid level sensor 10, a temperature sensor 11 and a water outlet 12. The water inlet 5 is located on the side wall of the water tank in the water supplementing area 2, and normal temperature water can enter the water supplementing area 2 through the water inlet 5. Specifically, a water inlet pipe (not shown in the figure) is arranged between the water inlet 5 and a water source, and a first water pump (not shown in the figure) is arranged on the water inlet pipe, which is used to deliver normal temperature water into the water tank. The steam inlet 6 and the condensed water outlet 7 are respectively located on the side wall of the water tank in the heating area 3. The heating coil 8 is arranged in the heating area 3 in a spiral shape, one end of the heating coil 8 is connected with a steam source through the steam inlet 6 and a steam delivery pipe (not shown in the figure), and the other end of the heating coil 8 is connected with the condensed water outlet 7. Steam in the heating coil 8 can heat the water in the water tank to a set temperature, and the steam after heat release becomes condensed water and flows out from the condensed water outlet 7. Specifically, a pneumatic diaphragm valve is arranged on the steam delivery pipe to control the opening and closing of the steam delivery pipe and the flow of steam.

[0040] The first liquid level sensor 9 is arranged in the measuring area 4, and is used to detect whether the height of the water in the water tank reaches a first preset height. The second liquid level sensor 10 is arranged in the measuring area 4 and below the first liquid level sensor 9, and is used to detect whether the water in the water tank reaches a second preset height, wherein the first preset height is greater than the second preset height. The first liquid level sensor 9 and the second liquid level sensor 10 are used to detect whether the water in the heating water tank reaches the highest water level and the lowest water level required by the tobacco stem water adding process, so as to prevent the phenomenon of water overflow due to too high water level and water shortage due to too low water level. The temperature sensor 11 is arranged in the measuring area 4, and is used to collect whether the temperature of the water in the measuring area 4 reaches a preset temperature, so as to ensure that the water sprayed into the tobacco stem meets the process requirements. The water outlet 12 is arranged on the side wall of the water tank in the measuring area 4, and the water in the measuring area 4 can be discharged through the water outlet 12 to humidify the tobacco stem. Further, because the temperature of water is stratified with different heights, that is, the temperature of water at different heights is not equal. Therefore, in the present application, the water outlet 12 and the temperature sensor 11 are arranged at the same height to ensure that the temperature of the water flowing out of the water outlet 12 meets the process requirements.

[0041] The above technical scheme is adopted, the water tank is divided into the water supplement area 2, the heating area 3 and the measurement area 4, the water inlet 5 and the water outlet 12 are arranged in the water supplement area 2, and the liquid level sensor and the temperature sensor 11 are arranged in the measurement area 4, so that the separation of the sensors from the water inlet 5 and the water outlet 12 is realized, the inaccurate detection of the first liquid level sensor 9 and the second liquid level sensor 10 caused by the water level fluctuation when the water tank is filled with water or the water pump is pumping is avoided, the direct contact of the normal temperature water with the temperature sensor 11 when the water is filled causes the temperature sensor 11 to be misdetected, and thus the tobacco quality can be improved; meanwhile, the water in the water tank is heated by using the heat release form of the tube wall of the heating coil 8, the direct contact of the steam with the water in the water tank is avoided, and thus the rust stains or dirt in the steam can be prevented from entering the water body to cause the water body pollution, and the tobacco quality can be further improved.

[0042] Optionally, the water outlet pipe (not shown in the figure) is further included, one end of the water outlet pipe is connected with the water outlet 12, the other end of the water outlet pipe is connected with the water using component (not shown in the figure), the height of the water using component is higher than the height of the heating water tank, the second water pump (not shown in the figure) is arranged on the water outlet pipe, and the second water pump is used to deliver the water in the heating water tank to the water using component.

[0043] Optionally, as shown in Figure 2 and Figure 4 , the heating water tank further includes the backwater inlet 13, which is arranged on the side wall of the water tank in the heating area 3, and the backwater inlet 13 is connected with the lower end of the water using component in communication through the backflow pipe (not shown in the figure), when the water pump stops running, the water in the water using component can flow back to the water tank under the action of gravity through the backflow pipe and the backwater inlet 13, since the backflow water still has a certain temperature, when the backflow water flows back to the heating area 3, the part of the water can quickly rise to the target temperature through the re-heating of the heating coil 8, and thus the heating efficiency and the utilization rate of the water can be improved.

[0044] Optionally, as shown in Figure 2 and Figure 4 , along the height direction of the water tank (as shown in the Z direction in Figure 4 ), the backwater inlet 13 is higher than the highest position of the heating coil 8, so as to prevent the backflow water from flowing out from the water outlet 12 without being heated by the heating coil 8, and along the horizontal direction (as shown in the X direction in Figure 4 ), the backwater inlet 13 is located between the steam inlet 6 and the condensed water outlet 7, so as to prevent the backflow water from being delivered to one side of the heating coil 8, and thus the water temperature on both sides of the heating coil 8 is inconsistent.

[0045] Optionally, as shown in Figure 2 and Figure 4As shown in the drawings, the heating water tank further comprises an overflow port 14 arranged on the sidewall of the water tank in the water supplement area 2, and the height of the overflow port 14 is higher than the height of the first liquid level sensor 9, so that when the height of the water in the water tank exceeds the first preset height, the water in the water tank can overflow from the overflow port 14, and the height of the overflow port 14 is lower than the height of the backflow port 13, so that when the liquid level in the water tank reaches the highest water level, the backflow water can still enter the water tank to utilize the water temperature of the backflow water.

[0046] Optionally, as shown in the drawings, Figure 1 and Figure 3 As shown in the drawings, the heating water tank further comprises a drain port 15 arranged on the bottom surface of the water tank, so that when the water in the heating water tank is turbid, the water tank can be emptied.

[0047] Optionally, as shown in the drawings, Figure 1 The heating water tank further comprises a cover body 16 detachably connected to the top of the heating water tank, so as to prevent pollutants from entering the heating water tank to pollute the water.

[0048] Optionally, the cover body 16 is externally provided with a heat preservation layer (not shown in the drawings), which can play a heat preservation role on the water in the heating water tank.

[0049] Optionally, as shown in the drawings, Figure 2 Figure 2 The partition plate 1 is a stainless steel plate, so as to improve the corrosion resistance and service life.

[0050] The heating water tank disclosed in the application further comprises a control system (not shown in the drawings) electrically connected with the first liquid level sensor 9, the second liquid level sensor 10, the temperature sensor 11, the first water pump, the second water pump and the pneumatic diaphragm valve. When the first liquid level sensor 9 detects that the water level in the water tank is higher than the first preset height, the control system controls the first water pump to be closed to stop water supplementing, and controls the pneumatic diaphragm valve to be opened to heat. When the second liquid level sensor 10 detects that the water level in the water tank is lower than the second preset height, the control system controls the pneumatic diaphragm valve to be closed to prevent dry burning. When the temperature sensor 11 detects that the temperature of the water in the water tank is higher than the preset temperature, the control system controls the pneumatic diaphragm valve to be reduced or closed, and when the temperature sensor 11 detects that the temperature of the water in the water tank is lower than the preset temperature, the control system controls the pneumatic diaphragm valve to be increased. When water needs to be supplied to the water using component, the control system controls the second water pump to operate to supply water to the water using component, and controls the first water pump to operate to supplement water to the water tank. When the tobacco stem humidification is finished, the control system controls the second water pump to be closed.

[0051] The working process of the heating water tank disclosed in the application is as follows:

[0052] (1) Preheating stage

[0053] When the tobacco stem needs to be sprayed with water for humidification, normal temperature water enters the water tank from the water inlet 5, and the water tank starts to supplement normal temperature water.When the water level is lower than the second preset height, the second liquid level sensor 10 sends a signal, and the control system controls the pneumatic diaphragm valve to be closed, at this time, the steam cannot enter to prevent dry burning.When the water level is higher than the first preset height, the first liquid level sensor 9 sends a signal, and the control system controls the pneumatic diaphragm valve to be opened, and the steam enters the heating coil 8 from the steam inlet 6 to heat the water in the water tank, and after heat exchange, the condensed water is discharged through the condensed water outlet 7.When the water temperature reaches the preset temperature, the control system controls the pneumatic diaphragm valve opening to be reduced or closed, so that the water temperature in the water tank is maintained within the required range.

[0054] (2) Water supply stage

[0055] The water temperature has reached the preset temperature, the control system controls the second water pump to run, and the hot water enters the water using component through the water outlet 12 and the water outlet pipe.Meanwhile, the control system controls the first water pump to run, and the normal temperature water enters the water tank from the water inlet 5, and the normal temperature water is supplemented in time.

[0056] (3) Water return stage

[0057] When the tobacco stem water adding is finished, the control system controls the second water pump to stop running, and the hot water in the water outlet pipe returns to the water tank from the water using component through the water return port 13 under the action of gravity.If too much water returns, the excess water will overflow from the overflow port 14.

[0058] In summary, the heating water tank provided by the utility model can avoid sensor misjudgment, prevent water pollution, and improve the quality of tobacco.

[0059] Although the utility model has been illustrated and described with reference to certain preferred embodiments, it should be understood by those skilled in the art that the above content is a further detailed description of the utility model combined with specific embodiments, and the specific implementation of the utility model cannot be limited to these descriptions.Those skilled in the art can make various changes in form and details, including making a number of simple inferences or substitutions, without departing from the spirit and scope of the utility model.
