Description

Technical Field

[0001] The utility model relates to the field of boilers, and more specifically to a boiler fixed-discharge drain heat recovery device. Background Art

[0002] A boiler is an energy conversion device. The energy input into the boiler includes chemical energy and electrical energy in the fuel, and the boiler outputs steam, high-temperature water or organic heat carrier with a certain amount of thermal energy.

[0003] The utility model with publication number CN209196826U discloses a boiler fixed-discharge drainage recovery system. It comprises a treated water container, a boiler, a boiler fixed-discharge drainage expansion tank, and a fixed-discharge expansion tank drainage collection tank which are connected in sequence. The boiler fixed-discharge drainage expansion tank is provided with an inlet in the middle, which is connected to the boiler through an inlet pipe, an exhaust port is provided at the top, and a drainage port is provided at the bottom. The drainage port is connected to the fixed-discharge expansion tank drainage collection tank through a drainage pipe. The fixed-discharge expansion tank drainage collection tank is connected to a circulating water cooling tower pool by installing a recovery water pump. The exhaust port is provided with an exhaust air pipe, and the exhaust air pipe is provided with a plurality of mist spray devices connected to the circulating water cooling tower pool. The mist spray device is connected to the circulating water cooling tower pool through a spray pipe. The spray device is provided with a number of spray holes. The above application documents use a drain pipe for drainage, and there are often some impurities remaining inside. When there are too many impurities, the pipe will be blocked. In response to this problem, the Chinese utility model with application number 202321003637.7 proposes a boiler fixed-discharge drain heat recovery device. When the device is in use, when the drain pipe starts to operate, water will flow through the pipe and drive the water wheel to start rotating, so that the water wheel drives the bevel gear to start rotating, so that the rotating rod and the rubber cylinder start to rotate and squeeze, so as to achieve the effect of crushing the impurities in the water without blocking the inside of the pipe. However, the problems existing in the device when in use are:

[0004] When the device crushes impurities in the water, it needs to squeeze the rubber tube to complete the operation. When the external water flows into the drain pipe to drive the bevel gear, the rubber tube needs a certain driving force to complete the squeezing operation. Therefore, it is difficult to ensure the squeezing of the rubber tube when water flows in the drain pipe, which in turn affects the crushing effect of the impurities. At the same time, the bevel gear drive is subject to the resistance caused by the squeezing of the rubber tube, and it is difficult to ensure its working stability.

[0005] Therefore, the utility model proposes a boiler fixed-discharge drain heat recovery device. Utility Model Content
