Description

Technical Field

[0001] This application belongs to the field of power plant wastewater sampling technology, specifically a sampling flow stabilizer. Background Technology

[0002] Wastewater sampling refers to the collection of representative water samples from industrial or domestic sewage systems for water quality analysis, pollution monitoring, or compliance testing. Sampling methods include manual sampling and automatic sampling, and the specific choice depends on the characteristics of the wastewater, the sampling frequency, and the site conditions.

[0003] Power plant wastewater is usually a high-temperature liquid, especially boiler drainage, cooling water or desulfurization wastewater, where the temperature can reach above 60 degrees Celsius or even close to the boiling point. During the sampling process, there is a risk of burns from high-temperature wastewater. Therefore, staff must wear protective gloves, masks, heat-resistant clothing and other protective gear to avoid splashes or steam burns.

[0004] Although protective gear can effectively protect workers from the harm of high-temperature wastewater, in actual operation, the heavy protective equipment can restrict the flexibility of the limbs and affect the accurate operation of sampling equipment. For example, wearing heat-resistant gloves can reduce the feel of the hand and increase the difficulty of valve adjustment or holding the sampling bottle; while the protective mask can fog up under the action of steam, which can affect the vision and make it difficult to observe the sampling process. These factors can reduce work efficiency and even lead to sampling errors. Therefore, a sampling flow stabilizer is proposed to solve the above problems. Utility Model Content

[0005] The purpose of this application is to address the shortcomings of existing technologies by designing a sampling flow stabilizer, which solves the problem that the use of protective gear in existing power plant wastewater sampling causes inconvenience to the sampling operation.

[0006] To achieve the above objectives, this application adopts the following technical solution:

[0007] A sampling flow stabilizer includes a housing, an inlet pipe fixedly connected to the right side of the housing, an outlet pipe fixedly connected to the left side of the housing, a cooling mechanism inside the housing, and a flow turbulence mechanism on the top of the housing.

[0008] The cooling mechanism includes a spiral tube, one end of which is fixedly connected to a discharge pipe, and the other end of which is fixedly connected to an injection pipe. Fins are fixedly connected through the inner wall of the housing. Sealed bearings are fixedly connected to the inner walls of both the discharge pipe and the injection pipe. A transmission rod is fixedly connected to the inner ring of the sealed bearing. A fan blade is fixedly connected to the end of the transmission rod near the fins. A connecting rod is fixedly connected to the outer wall of the transmission rod. A guide cup is fixedly connected to the end of the connecting rod away from the transmission rod.

[0009] Preferably, the aerodynamic mechanism includes a rotating rod that passes through and is rotatably connected to the top inner wall of the housing, and an aerodynamic plate is fixedly connected to the outer wall of the rotating rod.

[0010] Preferably, the bottom end of the rotating rod extends into the interior of the housing and is fixedly connected to a protrusion.

[0011] Preferably, a rotating shaft is rotatably connected through the top of the housing, and a connecting rod is hinged to the bottom end of the rotating shaft.

[0012] Preferably, the hinge point between the connecting rod and the rotating shaft is offset from the central axis of the rotating shaft, and the end of the connecting rod away from the rotating shaft is hinged to the bottom of the protrusion.

[0013] Preferably, a driven bevel gear is fixedly connected to the top end of the rotating shaft.

[0014] Preferably, a drive bevel gear is fixedly connected to the outer wall of the transmission rod, and the drive bevel gear meshes with the driven bevel gear.

[0015] Preferably, the guide cup is a hollow spherical structure with an opening.

[0016] This application has the following beneficial effects:

[0017] 1. This application allows for the temporary storage of high-temperature wastewater through the shell structure, preventing the wastewater from boiling and scalding workers. In conjunction with the cooling mechanism, the wastewater inside the shell can be cooled, thus maintaining a stable state. After cooling, the wastewater can be discharged through the outlet pipe for sampling, allowing workers to sample the high-temperature wastewater from the power plant without wearing protective gear, thereby improving the convenience of wastewater sampling.

[0018] 2. This application can increase the range of fan blade airflow by setting up a turbulence mechanism, so that the fins can be dissipated heat evenly, thereby further improving the heat conduction efficiency of the fins and thus improving the cooling efficiency of wastewater.

[0025] like Figure 1-3 As shown, a sampling flow stabilizer includes a housing 1. An inlet pipe 2 is fixedly connected to the right side of the housing 1, and an outlet pipe 3 is fixedly connected to the left side of the housing 1. High-temperature wastewater from a power plant is injected into the housing 1 through the inlet pipe 2. After the wastewater is cooled, it can be discharged from the housing 1 through the outlet pipe 3 for sampling. A cooling mechanism 4 is provided inside the housing 1, and a turbulence-inducing mechanism 5 is provided on the top of the housing 1.

[0026] like Figure 2-4 As shown, the cooling mechanism 4 includes a spiral tube 41. One end of the spiral tube 41 is fixedly connected to a discharge pipe 42. The coolant inside the spiral tube 41 is discharged outward through the discharge pipe 42. Then, a circulation pump pumps the discharged coolant back into the injection pipe 43, allowing the coolant to circulate within the spiral tube 41. The other end of the spiral tube 41 is fixedly connected to an injection pipe 43. An external circulation pump pumps the coolant into the injection pipe 43, allowing the coolant to enter the spiral tube 41 through the injection pipe 43. Fins 49 are fixedly connected to the inner wall of the housing 1. Sealed bearings 44 are fixedly connected to the inner walls of both the discharge pipe 42 and the injection pipe 43. The sealed bearings 44 can be PTFE lip-sealed bearings of model NSKTFL205. The support of the sealed bearings 44 allows the transmission rod 45 to rotate stably. The inner ring of the sealed bearing 44... A transmission rod 45 is fixedly connected, and a fan blade 46 is fixedly connected to one end of the transmission rod 45 near the fin 49. By rotating the transmission rod 45 and cooperating with the fan blade 46, air can be blown onto the fin 49, thereby increasing the airflow speed between the fins 49 to dissipate heat from the fins 49. A connecting rod 47 is fixedly connected to the outer wall of the transmission rod 45, and a guide cup 48 is fixedly connected to the end of the connecting rod 47 away from the transmission rod 45. The guide cup 48 is a hollow spherical structure with an opening. Because the guide cup 48 is a hollow and open spherical shape, the opening of the guide cup 48 will be impacted by the circulating coolant. Since its spherical outer surface is relatively smooth and the force-bearing surface is small, the coolant will only impact the opening of the guide cup 48 during circulation, causing the guide cup 48 to push the connecting rod 47, which in turn causes the connecting rod 47 to drive the transmission rod 45 to rotate.

[0027] like Figures 3-5The airflow disturbance mechanism 5 includes a rotating rod 51, which is rotatably connected to the top inner wall of the housing 1. A baffle 52 is fixedly connected to the outer wall of the rotating rod 51. As the rotating rod 51 reciprocates, it drives the baffle 52 to swing back and forth. The reciprocating swing of the baffle 52 guides the airflow from the fan blade 46 to the fin 49, thereby expanding the airflow range of the fan blade 46 and allowing the fin 49 to receive uniform heat dissipation. The bottom end of the rotating rod 51 extends into the interior of the housing 1 and is fixedly connected to a protrusion 53. A rotating shaft 54 ​​is rotatably connected to the top of the housing 1. A connecting rod 55 is hinged to the bottom end of the rotating shaft 54. The hinge point of the rotating shaft 54 ​​is off the central axis of the rotating shaft 54. The end of the connecting rod 55 away from the rotating shaft 54 ​​is hinged to the bottom of the protrusion 53. When the rotating shaft 54 ​​rotates, the connecting rod 55 and the protrusion 53 can drive the rotating rod 51 to reciprocate on the top inner wall of the housing 1. The top of the rotating shaft 54 ​​is fixedly connected to the driven bevel gear 56. The outer wall of the transmission rod 45 is fixedly connected to the driving bevel gear 57. The driving bevel gear 57 meshes with the driven bevel gear 56. When the transmission rod 45 rotates, it will drive the driving bevel gear 57 to rotate synchronously. When the driving bevel gear 57 rotates, it can drive the rotating shaft 54 ​​to rotate in conjunction with the driven bevel gear 56 that meshes with it.

[0028] Working Principle: During operation, high-temperature wastewater from the power plant is injected into the shell 1 through the inlet pipe 2. Simultaneously, an external circulation pump pumps coolant into the injection pipe 43, allowing the coolant to enter the spiral tube 41. The coolant inside the spiral tube 41 is then discharged through the outlet pipe 42. The circulation pump then pumps the discharged coolant back into the injection pipe 43, allowing the coolant to circulate within the spiral tube 41. This circulating coolant, in conjunction with the spiral tube 41, cools the high-temperature wastewater inside the shell 1. Because the spiral tube 41 has a spiral structure, the coolant can fully exchange heat with the high-temperature wastewater during circulation, thus improving the cooling effect. Simultaneously, the high-temperature wastewater inside the shell 1 conducts heat to the fins 49, where it exchanges heat with the external cold air, further enhancing the cooling effect. The cooling efficiency of high-temperature wastewater is improved. Simultaneously, because the guide cup 48 is a hollow, open spherical shape, the coolant will impact the opening of the guide cup 48 during its circulation within the spiral tube 41. This causes the guide cup 48 to push the connecting rod 47, which in turn drives the transmission rod 45 to rotate. Supported by the sealed bearing 44, the transmission rod 45 can drive the fan blades 46 to rotate smoothly. The rotation of the fan blades 46 blows air onto the fins 49, increasing the airflow speed between the fins 49 and facilitating heat dissipation. This allows for more efficient heat transfer, further improving the cooling efficiency of the high-temperature wastewater. The storage in the shell 1, combined with the cooling mechanism 4, effectively reduces the wastewater temperature, preventing it from boiling. The cooled wastewater can then be discharged through the outlet pipe 3, allowing for direct sampling.

[0029] As the transmission rod 45 rotates, it drives the drive bevel gear 57 to rotate synchronously. As the drive bevel gear 57 rotates, it engages with the driven bevel gear 56, which drives the rotating shaft 54 ​​to rotate. As the rotating shaft 54 ​​rotates, it pushes and pulls the connecting rod 55 back and forth, causing the connecting rod 55 to push and pull the protrusion 53 back and forth. At this time, the protrusion 53 drives the rotating rod 51 to rotate back and forth on the top inner wall of the housing 1. As the rotating rod 51 rotates back and forth, it drives the baffle 52 to swing back and forth. As the baffle 52 swings back and forth, it can guide the airflow from the fan blade 46 to the fins 49 to both sides of the fan blade 46, thereby expanding the airflow range of the fan blade 46 and allowing the fins 49 to receive uniform heat dissipation. This can further improve the heat transfer efficiency of the fins 49 and thus improve the cooling efficiency of the wastewater.
