Description

Technical Field

[0001] The utility model relates to the technical field of expanders, in particular to a periodic sewage discharge expander. Background Art

[0002] The periodic sewage expansion tank is also called the periodic sewage expander. The periodic sewage expander is used to separate the secondary steam and waste hot water from the boiler's periodic sewage or waste hot water with a higher pressure than the periodic sewage expander through decompression and expansion. The secondary steam is discharged into the atmosphere or used as a heat source, and the waste hot water is generally discharged into the sewer system through the sewage cooling tank.

[0003] For example, a Chinese patent discloses: a periodic sewage expansion container, patent number: CN214891103U, which is fixedly connected to the support plate by a first ring and a second ring, and the first telescopic rod and the second telescopic rod work at the same time. The second telescopic rod causes the first telescopic rod to rotate counterclockwise around the first support seat, so that the connecting piece moves downward along the slide groove. During this period, the first telescopic rod contracts, causing the expander body to rotate clockwise around the second support seat, and then the expander body is placed horizontally, thereby reducing the height of the expander body and facilitating the maintenance of the equipment. It is worthy of vigorous promotion.

[0004] However, during the implementation of the above technical solution, it was found that there were at least the following technical problems: as mentioned above, the device can only convert a small amount of high-temperature sewage into steam, which reduces the utilization rate of the high-temperature sewage and thus leads to poor practicality.

[0023] The embodiment of the present application provides a periodic sewage expansion tank, which effectively solves the problem that the above-mentioned device can only convert a small amount of high-temperature sewage into steam, reducing the utilization rate of the high-temperature sewage, resulting in poor practicality. The motor drives the spiral to rotate clockwise, and the spiral transmits the high-temperature wastewater from the inside of the water transfer pipe to the inside of the disc. When the high-temperature wastewater in the disc passes through the atomizing nozzle, it is atomized and returns to the inside of the expansion tank body. The disc will be forced to rotate, and the atomized wastewater will be evenly distributed inside the expansion tank body. The first gear drives the second gear shaft to rotate counterclockwise, and the second gear shaft drives the gear ring to rotate clockwise. The gear ring drives the stirring blade to move in a clockwise circular motion, stirring the high-temperature wastewater and accelerating the evaporation rate, thereby converting the high-temperature wastewater inside the expansion tank body into steam, improving the utilization rate of the high-temperature sewage. The gear ring drives the column to rotate counterclockwise, and the column drives the rotating blade to rotate counterclockwise. The rotating blade rotates slowly, which assists the steam at the bottom to move upward, drives the steam to combine with the water mist, accelerates the evaporation efficiency, and accelerates the speed at which the steam is discharged from the interior of the expansion tank body, thereby achieving the function of auxiliary drainage.

The stirring blade 24 is fixedly mounted on the side wall of the gear ring 28. The motor 16 drives the spiral body 17 to rotate clockwise. The spiral body 17 transfers the high-temperature wastewater from the inside of the water transfer pipe 18 to the inside of the disc 19. When the high-temperature wastewater inside the disc 19 passes through the atomizing nozzle 21, it is atomized and returns to the inside of the expander body 11. The disc 19 will be forced to rotate, and the atomized wastewater will be evenly distributed inside the expander body 11. The first gear 22 drives the second gear shaft 23 to rotate counterclockwise, and the second gear shaft 23 drives the gear ring 28 to rotate clockwise. The gear ring 28 drives the stirring blade 24 to move in a clockwise circular motion, stirring the high-temperature wastewater and accelerating the evaporation rate, thereby converting the high-temperature wastewater inside the expander body 11 into steam, thereby improving the utilization rate of high-temperature wastewater.

[0026] A motor 16 is fixedly installed inside the cylinder 14, and the output end of the motor 16 is fixedly installed to the spiral body 17. A column 25 is fixedly installed on the top of the gear ring 28. The column 25 is sleeved on the side wall of the water transfer pipe 18.

[0027] In response to the problems existing in the prior art, the utility model provides a periodic sewage expansion container. The motor 16 drives the spiral 17 to rotate clockwise. The spiral 17 transmits the high-temperature wastewater from the inside of the water transfer pipe 18 to the inside of the disc 19. When the high-temperature wastewater in the disc 19 passes through the atomizing nozzle 21, it is atomized and returns to the inside of the expansion container body 11. The disc 19 will be forced to rotate, and the atomized wastewater will be evenly distributed in the inside of the expansion container body 11. The first gear 22 drives the second gear shaft 23 to rotate counterclockwise, and the second gear shaft 23 drives the gear ring 28 to rotate clockwise. The gear ring 28 drives the stirring blade 24 to move in a clockwise circular motion, stirring the high-temperature wastewater and accelerating the evaporation rate, thereby converting the high-temperature wastewater inside the expansion vessel body 11 into steam, thereby improving the utilization rate of high-temperature wastewater. The gear ring 28 drives the column 25 to rotate counterclockwise, and the column 25 drives the rotating blade 26 to rotate counterclockwise. The rotating blade 26 rotates at a relatively slow speed, which assists the steam at the bottom to move upward, drives the steam to combine with the water mist, accelerates the evaporation efficiency, and accelerates the speed at which the steam is discharged from the interior of the expansion vessel body 11, thereby achieving the function of auxiliary drainage.

[0028] Working principle:

[0029] In the first step, high-temperature wastewater is put into the expansion vessel body 11 through the water inlet 15, and the motor 16 is started. The motor 16 drives the spiral 17 to rotate clockwise, and the spiral 17 transfers the high-temperature wastewater from the water transfer pipe 18 to the inside of the disc 19. When the high-temperature wastewater in the disc 19 passes through the atomizing nozzle 21, it is atomized and returns to the inside of the expansion vessel body 11. The atomizing nozzle 21 is tilted, and the disc 19 will be forced to rotate, and the atomized wastewater will be evenly distributed inside the expansion vessel body 11. At the same time, the spiral 17 drives the first gear 22 to rotate clockwise, the first gear 22 drives the second gear shaft 23 to rotate counterclockwise, and the second gear shaft 23 drives the gear ring 28 to rotate clockwise. The gear ring 28 drives the stirring blade 24 to move in a clockwise circular motion to stir the high-temperature wastewater, increase the contact area between the wastewater and the air, and accelerate the evaporation rate, so that the expansion vessel body 11 converts a large amount of high-temperature wastewater into steam, thereby improving the utilization rate of high-temperature wastewater.

[0030] In the second step, the gear ring 28 drives the column 25 to rotate counterclockwise, and the column 25 drives the rotating blades 26 to rotate counterclockwise. The rotating blades 26 rotate at a slower speed, which helps to drive the steam at the bottom to move upward, drives the steam to combine with the water mist, speeds up the evaporation efficiency, and speeds up the speed at which the steam is discharged from the inside of the expansion container body 11, thereby achieving the function of auxiliary drainage.
