Description

Technical Field

[0001] The utility model relates to the technical field of cigarette packaging equipment, in particular to a boiler water circulation cooling measuring and alarm device. Background Art

[0002] In the process of cigarette production, boiler steam is one of the indispensable production energy sources, and it is also an important prerequisite for the smooth production of cigarette products. In order to ensure the safe and reliable operation of the boiler, it is necessary to regularly test the alkalinity, pH value and conductivity of the boiler water. Since the temperature of the boiler water is too high when it flows out of the pipe, it needs to be cooled before the index test can be carried out. In order to facilitate the detection work, it is also necessary to use measuring tools such as measuring cups to measure the cooled boiler water to a certain test amount. Cooling the boiler water requires a large amount of tap water to flow and cool down, and the steps are relatively cumbersome. When measuring the boiler water capacity, it is also necessary to use a variety of instruments such as measuring cups, which have problems such as large resource loss, numerous steps, and low efficiency.

[0003] The existing boiler water cooling method is to use non-circulating flowing water for initial cooling, and then use instruments for immersion cooling. The initial cooling will consume a large amount of water resources, and the temperature of the boiler water is high when it is manually collected, which poses a certain risk of scalding. The existing measurement method is to use instruments such as volumetric cups for manual measurement, which involves many human factors and will lead to certain errors in the test results. Utility Model Content

[0004] In view of the above shortcomings, the utility model provides a boiler water circulating cooling measuring and alarm device, which can complete the circulating cooling and automatic measuring of boiler water through the circulating cooling system, measuring device and alarm device, and work regularly and the warning light will give an alarm, reminding the operator to conduct boiler water quality inspection on time, thereby reducing resource consumption, reducing manual operation steps and improving work efficiency.

[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0006] A boiler water circulating cooling measuring and alarm device comprises a box body, a high-temperature boiler water pipe is arranged on the box body, one end of the high-temperature boiler water pipe passes through the box body to the inside and is connected to a cooling chamber, a circulating cooling system for cooling boiler water is arranged in the cooling chamber, the circulating cooling system is arranged in the box body, a water intake tank is arranged at the bottom of the cooling chamber, a measuring device is fixedly installed in the water intake tank, an input end of the measuring device passes through the water intake tank and is connected to the cooling chamber, and an alarm device is arranged on the outside of the box body.

[0007] Through the above scheme, the circulating cooling system cools the boiler water in the cooling chamber. After the cooling is completed, the boiler water is measured by the measuring device to obtain a fixed amount of boiler water. During this period, an alarm is given through the alarm device, thereby reducing manual operation steps and improving work efficiency.

[0008] Furthermore, the circulating cooling system includes a motor, a coupling, a water pump, a cooling pipe, a thermostatic valve, a cooling water tank and a cooling fan. The cooling pipe is arranged in a cooling chamber, one end of the cooling pipe passes through one side of the cooling chamber to the outside of the cooling chamber and is connected with the water outlet of the cooling water tank, and the other end passes through the other side of the cooling chamber to the outside of the cooling chamber and is connected with the water inlet of the water pump. The water outlet of the water pump is connected with the water inlet of the thermostatic valve through the cooling pipe, and the water outlet of the thermostatic valve is connected with the water inlet of the cooling water tank through the cooling pipe. A cooling fan is provided on one side of the box body at a position corresponding to the cooling water tank. The power end of the water pump is connected to the motor through a coupling, and the motor, water pump, thermostatic valve and cooling water tank are all fixedly mounted on the bottom of the box body.

[0009] Through the above further scheme, the cooling pipe and the cooling water tank are filled with cooling water, the motor is started, and the water pump is driven to rotate through the coupling. The cooling water in the cooling pipe flows to the thermostatic valve through the cooling pipe, and then flows into the cooling water tank through the cooling pipe. The cooling water tank cools the internal cooling water through the cooling fan, and then enters the cooling pipe in the cooling chamber through the cooling pipe, thereby absorbing the heat of the boiler water in the cooling chamber, and flows to the thermostatic valve through the water pump, completing a cycle, thereby reducing the temperature of the boiler water in the cooling chamber.

[0010] Furthermore, the temperature-control valve is provided with a first water outlet and a second water outlet, the first water outlet is connected to the cooling water tank through a cooling pipe, and the second water outlet is connected to a cooling pipe connected to the water outlet end of the cooling water tank through a cooling pipe.

[0011] Through the above further scheme, the thermostat valve detects that the temperature of the cooling water needs to flow into the cooling water tank for cooling, and the thermostat valve controls the valve to allow the cooling water to flow back into the cooling water tank. At this time, the circulating cooling system performs large-circulation loop cooling. The thermostat valve detects that the temperature of the cooling water does not need to flow into the cooling water tank for cooling, then the thermostat valve controls the valve to allow the cooling water to flow back into the cooling pipe of the cooling chamber. At this time, the circulating cooling system performs small-circulation loop cooling. The large-circulation cooling can quickly cool the boiler water in the cooling chamber, and the small-circulation cooling can reduce the cooling speed of the boiler water in the cooling chamber and save unnecessary energy consumption.

[0012] Furthermore, a liquid level sensor and a temperature sensor are fixedly installed on one side of the cooling chamber.

[0014] Furthermore, a drain pipe is provided at the bottom of the cooling chamber, and the drain pipe passes through the water intake tank and the box body to the outside of the box body. A drain electric valve is provided on the drain pipe inside the water intake tank.

[0015] Through the above further solution, the drain pipe is used to drain the remaining boiler water in the cooling chamber, and the drain electric valve is used to control the opening or closing of the drain pipe.

[0016] Furthermore, the measuring device includes a low-temperature furnace water pipe, an electromagnetic flowmeter, a water intake electric valve and a water cup. One end of the low-temperature furnace water pipe is connected to the cooling chamber, and the other end passes through the water intake tank to the inside of the water intake tank. An electromagnetic flowmeter and a water intake electric valve are provided on the low-temperature furnace water pipe. The electromagnetic flowmeter is located above the water intake electric valve. A water cup is placed in the water intake tank directly below the low-temperature furnace water pipe.

[0017] Through the above further scheme, the water intake electric valve is opened, the electromagnetic flowmeter valve is opened, and the cooled boiler water flows from the cooling chamber through the low-temperature furnace water pipe, through the electromagnetic flowmeter, and the water intake electric valve to the water cup.

[0018] Furthermore, the alarm device includes a warning light and a timer. The warning light is fixedly mounted on the top of the box through a lamp pole, and the timer is arranged on the lamp pole.

[0019] Compared with the prior art, the beneficial effects of the utility model are as follows: through the circulating cooling system, the measuring device and the alarm device, the tedious steps of manual cooling and measuring of boiler water are eliminated, labor is effectively saved, and the boiler water capacity can be accurately measured for subsequent detection work. It has a reasonable structure, is easy to operate, and has high cooling efficiency.

[0029] Reference Figure 1-Figure 4The preferred embodiment of the utility model provides a boiler water circulation cooling measuring and alarm device, including a box body 1, a high-temperature boiler water pipe 11 is arranged on the box body 1, one end of the high-temperature boiler water pipe 11 is connected with the boiler water main pipe 7, and the other end passes through the box body 1 to the inside to connect with the cooling chamber 2, and a water inlet electric valve 111 is arranged on the high-temperature boiler water pipe 11, which is used to control the water in the boiler water main pipe 7 to enter the cooling chamber 2, and a liquid level sensor 21 and a temperature sensor 22 are fixedly installed on one side of the cooling chamber 2. The temperature sensor 22 is used to detect the temperature of the boiler water in the cooling chamber 2, and the liquid level sensor 21 is used to detect the amount of boiler water in the cooling chamber 2. A cooling pipe 34 is arranged in the cooling chamber 2, and one end of the cooling pipe 34 passes through one side of the cooling chamber 2 to the outside of the cooling chamber 2 and is connected with the water outlet end of the cooling water tank 36, and the other end The cooling fan 37 is provided on one side of the box body 1 at a position corresponding to the cooling water tank 36.

The motor 31, the water pump 33, the thermostatic valve 35 and the cooling water tank 36 are all fixedly mounted on the bottom of the box body 1. The cooling pipe 34 and the cooling water tank 36 are filled with cooling water. The machine 31 is started, and the water pump 33 is driven to rotate through the coupling 32. The cooling water in the cooling pipe 34 flows to the thermostatic valve 35 through the cooling pipe 34. The thermostatic valve 35 detects that the temperature of the cooling water needs to flow into the cooling water tank 36 for cooling. The thermostatic valve 35 controls the valve to allow the cooling water to flow back to the cooling water tank 36 through the first water outlet 351. The cooling water tank 36 cools the internal cooling water through the cooling fan 37, and then enters the cooling pipe 34 in the cooling chamber 2 through the cooling pipe 34, and then absorbs the heat of the boiler water in the cooling chamber 2, and flows to the thermostatic valve 35 through the water pump 33 to complete a cycle. At this time, the circulating cooling system 3 performs large circulation loop cooling. The thermostatic valve 35 detects that the temperature of the cooling water does not need to flow into the cooling water tank 36 for cooling. Then the thermostatic valve 35 controls the valve to allow the cooling water to flow back into the cooling pipe 34 of the cooling chamber 2 through the second water outlet 352, and flows to the thermostatic valve 35 through the water pump 33 to complete a cycle. At this time, the circulating cooling system 3 performs small circulation loop cooling. The large circulation cooling can quickly cool the boiler water in the cooling chamber 2. The small circulation cooling can reduce the cooling speed of the boiler water in the cooling chamber 2 and save unnecessary energy consumption. A water intake tank 4 is provided at the bottom of the cooling chamber 2. A low-temperature boiler water pipe 51 is connected to the bottom of the cooling chamber 2. The low-temperature boiler water pipe 51 is connected end to end with the cooling chamber 2 and passes through the water intake tank 4 to the inside of the water intake tank 4. An electromagnetic flowmeter 52 and a water intake electric valve 53 are provided on the low-temperature boiler water pipe 51. The electromagnetic flowmeter 52 is located above the water intake electric valve 53.A water cup 54 is placed in the water intake tank 4 directly below the low-temperature furnace water pipe 51. The water intake electric valve 53 is opened, and the electromagnetic flowmeter 52 valve is opened. The cooled boiler water flows from the cooling chamber 2 through the low-temperature furnace water pipe 51, and then through the electromagnetic flowmeter 52 and the water intake electric valve 53 to the water cup 54. A drain pipe 23 is provided at the bottom of the cooling chamber 2. The drain pipe 23 runs through the water intake tank 4 and the box body 1 to the outside of the box body 1. A drain electric valve 231 is provided on the drain pipe 23 in the water intake tank 4. The drain pipe 23 is used to discharge the remaining boiler water in the cooling chamber 2. The drain electric valve 231 is used to control the opening or closing of the drain pipe 23. The top of the box body 1 is fixedly connected to a warning light 61 through a lamp pole 63, and a timer 62 is provided on the lamp pole 63.

[0030] Among them, refer to Figure 3 As shown, the cooling pipe 34 inside the cooling chamber 2 is divided into multiple branches 341 for rapid circulation and cooling of high-temperature boiler water.

[0031] A switch 12 is installed on one side of the box 1, including a start button and a close button.

[0032] The water intake tank 4 is provided with a protective door 41 , and a handle is provided on the protective door 41 .

[0033] Wherein, the box body 1 is provided with an inspection door 13 .

[0034] The warning lights 61 include a green light 611 and a yellow light 612, which are used to warn of different situations, so that the operator can quickly and accurately determine which situation the warning is in.

[0035] Among them, a support leg 14 is provided under the box body 1 for supporting the box body 1 at a certain height, so as to facilitate connection with the boiler water main pipe 7 and facilitate drainage by the drain pipe 23 .

[0036] It should be noted that the inner wall of the low-temperature furnace water pipe 51 should be smooth and free of water accumulation to ensure the accuracy of the water intake.

[0037] It should be noted that the installation position of the sensor should meet actual needs to ensure that the measured boiler water volume and water temperature meet the set requirements.

[0038] It should be noted that the material of the inner wall of the cooling chamber 2 should have a certain temperature reduction function and should have a certain thickness to avoid accidental burns to personnel.

[0039] It should be noted that the electromagnetic flowmeter 52 installed on the low-temperature furnace water pipe 51 should be in direct contact with the bottom of the cooling chamber 2 as much as possible to avoid furnace water remaining in the low-temperature furnace water pipe 51 after water is taken, which will affect the next detection result.

[0040] It should be noted that in order to achieve a rapid cooling effect, the cooling pipe 34 pipeline should be designed according to actual needs, and the models and sizes of the required components, sensors, etc. should be designed according to actual requirements to maximize space saving, reduce losses and reduce costs.

[0041] The following is a specific exemplary use process of a boiler water circulation cooling measuring and alarm device 6 according to a preferred embodiment of the utility model:

[0042] 1. Press the start button and the timer 62 starts working;

[0043] 2. When the time interval does not reach the set value, the green indicator light 611 is always on, indicating that it is in the normal timing state;

[0044] 3. When the timer 62 reaches the set value, i.e., the time for the boiler water detection, the water inlet electric valve 111 opens, the high-temperature boiler water enters the cooling chamber 2, and the green indicator light 611 turns green and keeps flashing. At this time, the boiler water is in a circulating cooling state;

[0045] 4. When the liquid level sensor 21 detects that the amount of boiler water in the cooling chamber 2 reaches a set threshold, the water inlet electric valve 111 is closed;

[0046] 5. When the water inlet electric valve 111 is closed, the circulating cooling system 3 starts to work; the motor 31 starts, the starting coupling 32 rotates, and then drives the water pump 33 to work. Under the action of the water pump 33, the cooling water in the cooling water tank 36 flows to the cooling pipe 34, passes through the cooling chamber 2, and then flows back to the water pump 33, and then flows through the thermostatic valve 35;

[0047] 6. If the thermostatic valve 35 detects that the temperature of the cooling water needs to flow into the cooling water tank 36 for cooling, the thermostatic valve 35 controls the valve to allow the cooling water to flow back into the cooling water tank 36, and the cooling fan 37 is started. At this time, the circulating cooling system 3 performs large-circulation loop cooling;

[0048] 7. If the thermostatic valve 35 detects that the temperature of the cooling water does not need to flow into the cooling water tank 36 for cooling, the thermostatic valve 35 controls the valve to allow the cooling water to flow back into the cooling pipe 34 of the cooling chamber 2. At this time, the circulating cooling system 3 performs small circulation loop cooling;

[0049] 8. When the temperature sensor 22 detects that the high-temperature boiler water has cooled to the set threshold temperature, the green indicator light 611 goes out and the yellow indicator light 612 stays on. This indicates that the boiler water is ready to be measured.

[0050] 9. When the yellow indicator light 612 is always on, the water intake electric valve 53 on the low-temperature furnace water pipe 51 is opened, the valve of the electromagnetic flowmeter 52 is opened, and the cooled furnace water flows from the cooling chamber 2 through the electromagnetic flowmeter 52 and the water intake electric valve 53 to the water cup 54;

[0051] 10. When the electromagnetic flowmeter 52 detects that the boiler water flowing through has reached the set value, the valve of the electromagnetic flowmeter 52 is closed, and the water intake electric valve 53 is closed after a certain delay, ensuring that all the boiler water passing through the electromagnetic flowmeter 52 flows into the water cup 54;

[0052] 11. At this time, the yellow indicator light 612 changes from a normally yellow light state to a bright yellow light and keeps flashing, and an alarm sounds, indicating that the state of taking boiler water for circulating cooling is completed, warning and reminding the operator to take water for testing in time;

[0053] 12. Since the boiler water threshold value set by the liquid level sensor 21 should be sufficient to ensure that a sufficient amount of boiler water is measured, the drain electric valve 231 on the drain pipe 23 is opened at this time to drain a small amount of boiler water in the cooling chamber 2 to avoid affecting the next boiler water detection index result. Before the water inlet electric valve 111 opens the instruction, the drain electric valve 231 is closed;

[0054] 13. Press the close button.

[0055] The above are only specific implementations of the utility model, but the protection scope of the utility model is not limited thereto. Any changes or substitutions that can be easily thought of by a person skilled in the art within the technical scope disclosed by the utility model should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model should be based on the protection scope of the claims.
