Description

Technical Field

[0001] The utility model relates to the technical field of boilers, and more specifically, to a boiler steam-water sampling device. Background Art

[0002] Boiler steam-water sampling is a device for taking water samples that meet the water temperature requirements for testing. By collecting and liquefying the boiler steam to form water, and then cooling the water, it can be used. The collected water is used for testing items, effectively avoiding the influence of impurities in the water on the test.

[0003] Currently, the method of sampling boiler steam-water is to collect the steam in a cooling chamber, and the steam is cooled into a liquid by the cooling chamber. However, in actual use, since the steam pipeline is connected to the cooling chamber, the steam generated by the boiler will continuously be transported into the interior of the cooling chamber, which results in a large amount of liquid being generated in the cooling chamber. However, the water used for testing is limited, and the excessive collected water cannot be used. It is difficult to ensure that the water quality is clean and impurity-free after being placed for a period of time, resulting in waste. Therefore, a boiler steam-water sampling device is proposed to solve the above problems. Summary of the Utility Model

[0004] To make up for the above deficiencies, the utility model provides a boiler steam-water sampling device that overcomes the above technical problems or at least partially solves the above problems.

All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts belong to the scope of protection of the present utility model.

[0029] Embodiment

[0030] Refer to Figures 1 - 5, the present utility model provides a technical solution: a boiler steam-water sampling device, which includes a base 1 and a sampling mechanism 3, and a boiler body 2 is fixedly installed on the upper surface of the base 1. The sampling mechanism 3 includes a cooling chamber 31 installed outside the boiler body 2. The top of the cooling chamber 31 is connected to an intake pipe 311, and one end of the intake pipe 311 is fixedly installed inside the boiler body 2. A serpentine pipe 32 is fixedly installed inside the cooling chamber 31, and the inside of the serpentine pipe 32 is communicated with the inside of the intake pipe 311. A floating block 33 is arranged inside the serpentine pipe 32, and a spherical block 331 is fixedly connected to the upper surface of the floating block 33.

[0031] In a preferred embodiment, a liquid inlet pipe 4 and a liquid outlet pipe 5 are fixedly installed on the outer surface of the boiler body 2, control valves 6 are fixedly installed on the outer surfaces of the liquid outlet pipe 5 and the liquid inlet pipe 4, and a controller 7 is also fixedly installed on the outer surface of the boiler body 2. This device adds liquid into the boiler body 2 and heats it to generate steam for collection and use. To facilitate adding liquid, a liquid outlet pipe 5 and a liquid inlet pipe 4 are installed on the boiler body 2 to facilitate water inlet and drainage of the boiler body 2 for convenient use.

[0032] In a preferred embodiment, a circular plate 8 is fixedly installed inside the serpentine pipe 32. A plurality of circular holes 9 are opened on the upper surface of the circular plate 8 and are evenly arranged on the upper surface of the circular plate 8. The floating block 33 is placed on the circular plate 8. This device installs a circular plate 8 inside the serpentine pipe 32 to control the gas input volume into the serpentine pipe 32. The floating block 33 is arranged on the circular plate 8, and a spherical block 331 is fixedly installed on the floating block 33. As the liquid continuously rises inside the serpentine pipe 32, the floating block 33 will move upward, thereby controlling the spherical block 331 to move to the bottom position of the intake pipe 311 and abut against the bottom opening of the intake pipe 311, so that the intake pipe 311 cannot input gas into the serpentine pipe 32 to meet the use requirements.

[0033] In a preferred embodiment, a drain pipe 10 is fixedly installed on the outer surface of the cooling chamber 31, and a control valve 6 is also arranged on the outer surface of the drain pipe 10. The inside of the drain pipe 10 is communicated with the inside of the serpentine pipe 32. After the steam enters the inside of the serpentine pipe 32, it will be liquefied under the action of the cooling chamber 31 to turn the steam into liquid. When no more gas enters the serpentine pipe 32, the control valve 6 on the drain pipe 10 can be opened to drain the water inside the serpentine pipe 32 through the drain pipe 10 to facilitate draining the liquid.

[0034] When the intake pipe 311 is blocked, the gas inside the intake pipe 311 will accumulate inside the intake pipe 311. As the gas continues to increase, the air pressure inside the intake pipe 311 will rise. To prevent danger, a pressure detector 11 and an electronic pressure relief valve 12 are installed outside the intake pipe 311. The pressure detector 11 is electrically connected to the PLC controller 13, and the PLC controller 13 is electrically connected to the electronic pressure relief valve 12. When the air pressure inside the intake pipe 311 rises, the pressure inside the intake pipe 311 can be detected by the pressure detector 11. When the air pressure inside the intake pipe 311 exceeds the set value, the electronic pressure relief valve 12 will be controlled by the PLC controller 13 to open, relieving the pressure inside the intake pipe 311 and avoiding danger.

[0035] In this device, steam enters the inside of the serpentine pipe 32 and turns into water inside the serpentine pipe 32. After each time the water is drained from the inside of the serpentine pipe 32, to prevent impurities from remaining, it is necessary to flush the inside of the serpentine pipe 32 after each drainage. Therefore, a flushing mechanism 14 is installed outside the cooling chamber 31. The flushing mechanism 14 includes a liquid pump 141, a water delivery pipe 142, and a check valve 143. A positioning plate 15 is fixedly installed on the outer surface of the boiler body 2. The liquid pump 141 is fixedly installed on the upper surface of the positioning plate 15. The water inlet end of the liquid pump 141 is fixedly installed with a water inlet pipe 16, and the water outlet end is fixedly installed with a water delivery pipe 142. One end of the water delivery pipe 142 is fixedly connected to the intake pipe 311. Check valves 143 are installed outside both the intake pipe 311 and the water delivery pipe 142.

[0036] During actual use, the liquid pump 141 is turned on, and the liquid inside the boiler body 2 is extracted by the liquid pump 141. At this time, ordinary water is contained inside the boiler body 2, and the heated water has been drained. The water is then delivered to the inside of the intake pipe 311 through the water delivery pipe 142. Since a check valve 143 is installed outside the intake pipe 311, after the water enters the intake pipe 311, it will directly enter the inside of the serpentine pipe 32. By continuously flushing with water inside the serpentine pipe 32, the impurities inside the serpentine pipe 32 can be cleaned to ensure later use.

[0037] Specifically, the working process or working principle of a boiler steam and water sampling device is as follows: Currently, the method of sampling boiler steam and water is to collect steam in a cooling chamber and cool the steam into a liquid through the cooling chamber. However, in actual use, since the steam delivery pipe 142 is connected to the cooling chamber, the steam generated by the boiler will continuously be delivered to the inside of the cooling chamber, which results in a large amount of liquid being generated inside the cooling chamber. The water used for testing is limited, and the excessive collected water cannot be used. It is difficult to ensure that the water quality is clean and free of impurities after being placed for a period of time, causing waste. Therefore, this device is designed to solve this problem.

[0038] This device can control the amount of water sampled to avoid waste caused by excessive water intake. The specific operation is as follows: Connect to an external power supply, add water from the outside to the inside of the boiler body 2 through the liquid inlet pipe 4, and then energize and heat the boiler body 2 to heat the water inside the boiler body 2. After heating for a period of time, a large amount of steam will be generated inside the boiler body 2. The steam moves upward inside the boiler body 2 and is discharged to the outside of the boiler body 2 through the air inlet pipe 311. As the steam continues to increase, the steam inside the air inlet pipe 311 will enter the inside of the serpentine pipe 32. The serpentine pipe 32 is installed inside the cooling chamber 31. When the cooling chamber 31 operates, the temperature inside the cooling chamber 31 will drop to cool the steam, causing the steam to turn into liquid inside the serpentine pipe 32.

[0039] As the boiler body 2 continuously generates steam and transports it to the inside of the serpentine pipe 32, and at the same time, under the continuous cooling of the cooling chamber 31, the liquid inside the serpentine pipe 32 will continuously increase. As the liquid inside the serpentine pipe 32 continues to increase, the floating block 33 will gradually move upward. To prevent the circular plate 8 from affecting the downward flow of the liquid inside the serpentine pipe 32, a circular hole 9 is provided on the circular plate 8, and the liquid will flow downward through the position of the circular hole 9. When the liquid inside the serpentine pipe 32 moves up to the position of the floating block 33, the floating block 33 will float upward. As the liquid inside the serpentine pipe 32 continues to accumulate, it will control the floating block 33 to continue moving upward and drive the spherical block 331 to also move upward until the spherical block 331 abuts against the bottom opening of the air inlet pipe 311.

[0040] After the bottom opening of the air inlet pipe 311 is blocked by the spherical block 331, the steam inside the air inlet pipe 311 cannot be transported to the inside of the serpentine pipe 32 and will accumulate inside the air inlet pipe 311. When the air pressure detector 11 detects that the air pressure inside the air inlet pipe 311 reaches the set air pressure value as the air pressure inside the air inlet pipe 311 continuously increases, the PLC controller 13 will control the electronic pressure relief valve 12 to open to relieve the pressure inside the air inlet pipe 311 in a timely manner.

[0041] Then, the liquid inside the coiled pipe 32 can be discharged through the inside of the drain pipe 10. Since water quality will adhere to the inner wall of the coiled pipe 32 after the liquid flows through it, and steam is discharged through the inside of the boiler body 2, it is inevitable that impurities will be mixed in. If not cleaned, it will affect subsequent use and easily cause other substances to be contained in the collected water, affecting the accuracy of material testing. Therefore, after all the liquid inside the coiled pipe 32 is discharged, the liquid extractor 141 can be turned on to extract the liquid inside the boiler body 2 through the liquid extractor 141. At this time, ordinary water is contained inside the boiler body 2, and the heated water has been discharged. Then, the water is conveyed to the inside of the air inlet pipe 311 through the water delivery pipe 142. Since a check valve 143 is installed outside the air inlet pipe 311, the water will directly enter the inside of the coiled pipe 32 after entering the air inlet pipe 311. By continuously flushing the inside of the coiled pipe 32 with water, the impurities inside the coiled pipe 32 can be cleaned to ensure subsequent use.

[0042] It should be noted that the air pressure detector 11, the electronic pressure relief valve 12, the PLC controller 13, and the liquid extractor 141 are devices or equipment existing in the prior art, or devices or equipment that can be realized by the prior art. Their power supply, specific composition, and principle are clear to those skilled in the art, so they will not be elaborated in detail.
