Description

Technical Field

[0001] The utility model belongs to the technical field of boiler blowdown pipes, in particular to a built-in blowdown pipe for a lower header applicable to boilers of various forms. Background Art

[0002] Boiler blowdown refers to the regular discharge of boiler water contaminated by slag. The built-in blowdown pipe in the lower header is a water pipe connected to the boiler blowdown port and installed inside the lower header. When the boiler waste water or exhaust gas needs to be discharged, it can be discharged from the boiler through the blowdown pipe and then sent to the heat exchanger for reuse.

[0003] In the prior art, when wastewater or waste gas is sent back into the heat exchanger, impurities in the wastewater or waste gas will directly enter the heat exchanger along with the wastewater or waste gas, causing wear and corrosion to the mechanical parts in the heat exchanger. At the same time, the sewage pipe needs to be disassembled for cleaning, which is very cumbersome. To this end, we provide a built-in sewage pipe in the lower header applicable to various types of boilers to solve the above problems. Utility Model Content

At the same time, the blocking plate moves upward under the drive of the power drive component, and the sewage outlet is opened. Impurities remaining in the sewage pipe will fall into a cleaning drawer, and then the staff can take out the cleaning drawer to deal with the filtered impurities. This process can filter the impurities into the sewage pipe, and then the staff only needs to deal with the cleaning drawer, which solves the problems of inconvenient cleaning and low efficiency caused by the need to disassemble the sewage pipe.

[0005] In order to solve the above technical problems, the utility model is achieved through the following technical solutions:

[0011] The utility model has the following beneficial effects:

[0012] 1. The utility model filters impurities in waste water or exhaust gas through the filter plate.

This process can filter the impurities into the sewage pipe, and then the staff only needs to deal with the cleaning drawer.

[0013] 2. The utility model drives the driving rack to move through the driving motor, and the movement of the driving rack drives the driving gear ring to rotate, thereby driving the rotating ring to rotate. At this time, the cleaning plate rotates along the inner wall of the sewage pipe, thereby cleaning the impurities remaining on the inner wall. The driving gear ring rotates while driving the power gear to rotate. At this time, the lifting rack moves upward along the limit opening to drive the sealing plate to move, and the sealing plate is released from the sewage outlet. When the cleaning plate moves to the highest point along the inner wall of the sewage pipe, the sealing plate is fitted with the inner wall of the sewage pipe. After the cleaning plate has cleaned the impurities on the inner wall of the sewage pipe, the driving motor is rotated in the opposite direction, and the driving rack moves in the opposite direction to drive the driving gear ring to rotate in the opposite direction, and at the same time, it will drive the power gear to rotate in the opposite direction, and the sealing plate is re-fitted with the sewage outlet. Therefore, the impurities inside the sewage pipe can be continuously and automatically cleaned through the cleaning plate, and there is no need to disassemble the sewage pipe, which greatly improves the efficiency of the staff.

A sewage outlet 104 is opened on the side of the sewage pipe 101, and a sealing plate 105 is installed above the sewage outlet 104.

[0031] The operation process of this embodiment is as follows: in the initial state, the lower surface of the sealing plate 105 is in contact with the sewage outlet 104, the cleaning drawer 402 is located inside the collecting box 401, and the sewage pipe 101 is connected to the boiler. When waste water or waste gas is discharged from the boiler into the sewage pipe 101, the filter plate filters out impurities in the waste water or waste gas. When the boiler stops draining or exhausting, under the action of the power drive component 3, the driving gear ring 301 will drive the cleaning plate 102 to rotate along the sewage pipe 101, thereby cleaning the impurities remaining on the inner wall of the sewage pipe 101. At the same time, the sealing plate 105 is driven by the driving gear ring 301 to separate from the inner wall of the sewage pipe 101. At this time, the sewage outlet 104 is opened, and the impurities remaining in the sewage pipe 101 will fall into the cleaning drawer 402. Then the staff can take out the cleaning drawer 402 to deal with the filtered impurities.

[0032] Specifically, embodiment 2 is based on embodiment 1. A lifting rack 106 is fixedly provided on one side of the blocking plate 105. The rotating assembly 2 also includes a limit ring 203.
