Description

Technical Field

[0001] This application relates to the field of deaerator technology, and in particular to an automatic exhaust device for a deaerator. Background Technology

[0002] Deaerators are one of the key pieces of equipment in boilers and heating systems. If a deaerator has poor deoxygenation capacity, it will cause serious corrosion to boiler feedwater pipes, economizers, and other auxiliary equipment, resulting in economic losses that will be tens or hundreds of times the cost of the deaerator. Therefore, the Ministry of Electric Power has put forward some standards for the oxygen content of deaerators, namely, the oxygen content of feedwater for atmospheric deaerators should be less than 15 μg / L, and the oxygen content of feedwater for pressure deaerators should be less than 7 μg / L.

[0003] Currently, during deaerator exhaust operation, when the deaerator stops exhausting, external air, water vapor, or impurities flow back into the deaerator through the exhaust pipe, affecting the deaerator's service life. Therefore, to address the above problem, an automatic exhaust device for deaerators is proposed. Utility Model Content

[0008] Furthermore, the threaded cylinder is threadedly connected to the inner thread on the top inner wall of the exhaust pipe via an external thread on its outer surface.

[0009] Furthermore, the elastic component includes a connecting cylinder, a threaded ring, an elastic spring, a slide block, and a sliding column. The connecting cylinder is slidably connected to the inner cavity of the guide ring. A guide plate is fixedly connected to the inner wall of the top end of the connecting cylinder. A sliding column is slidably connected to the inner wall of the connecting cylinder. A sliding column is fixedly connected to the top side of the slide block. The top end of the sliding column is fixedly connected to the anti-backflow plate.

[0010] Furthermore, an elastic spring is sleeved at the bottom end of the connecting cylinder, the elastic spring is disposed between the guide ring and the threaded ring, and the threaded ring is threadedly connected to the bottom end surface of the connecting cylinder.

[0021] The automatic exhaust device according to the embodiments of this application is described below.

[0022] Please see Figure 1-3 As shown, an automatic exhaust device for a deaerator includes a deaerator body 1, and a support bracket 2 for support is installed on the bottom side of the deaerator body 1. Exhaust pipe 3, which is installed at the exhaust port of the deaerator body 1, is used for gas discharge; Replacement component 4, which is detachably installed at the top of exhaust pipe 3, and has an elastic component 5 installed inside it; An anti-backflow plate 6 is installed at the top of an elastic component 5, which is used to quickly reset the anti-backflow plate 6 when no exhaust is being discharged.

[0023] The replacement component 4 includes a rotating ring 41, a threaded cylinder 43, a connecting post 44, and a guide ring 45. The inner wall of the rotating ring 41 is fixedly connected to the threaded cylinder 43, which is threadedly connected to the top end of the exhaust pipe 3. The inner wall of the top end of the threaded cylinder 43 is fixedly connected to the connecting post 44, and the end of the connecting post 44 is fixedly connected to the guide ring 45.

[0024] Multiple rotating blocks 42 are fixedly connected to the outer surface of the rotating ring 41, and the multiple rotating blocks 42 are distributed in a ring on the outer surface of the rotating ring 41.

[0025] The threaded cylinder 43 is threadedly connected to the internal thread on the inner wall of the top of the exhaust pipe 3 via an external thread on its outer surface.

[0026] The elastic component 5 includes a connecting cylinder 51, a threaded ring 52, an elastic spring 53, a slide block 54, and a sliding column 56. The connecting cylinder 51 is slidably connected to the inner cavity of the guide ring 45. A guide plate 55 is fixedly connected to the inner wall of the top end of the connecting cylinder 51. The sliding column 56 is slidably connected to the inner wall of the connecting cylinder 51. The sliding column 56 is fixedly connected to the top side of the slide block 54. The top end of the sliding column 56 is fixedly connected to the anti-backflow plate 6.

[0027] The bottom end of the connecting cylinder 51 is fitted with an elastic spring 53. The elastic spring 53 is located between the guide ring 45 and the threaded ring 52. The threaded ring 52 is threadedly connected to the bottom surface of the connecting cylinder 51. After removing and replacing component 4, the threaded ring 52 can be unscrewed separately, and the aged elastic spring 53 or the faulty connecting cylinder 51 and sliding column 56 can be taken out, replaced with new parts, and then reassembled.

[0028] In use, the electrical components described in this application are all externally connected to a power supply and control switch. By rotating the annularly distributed rotating block 42 on the outer side of the rotating ring 41, the threaded cylinder 43 fixed on the inner wall is driven to rotate. The external thread on the outer side of the threaded cylinder 43 engages with the internal thread on the inner wall of the top of the exhaust pipe 3, firmly fixing the entire replacement assembly 4 to the top of the exhaust pipe 3, forming a transition channel for gas discharge. The connecting cylinder 51 is slidably inserted into the inner cavity of the guide ring 45, and then an elastic spring 53 is fitted onto the bottom end of the connecting cylinder 51. The elastic spring 53 is limited between the bottom side of the guide ring 45 and the top side of the threaded ring 52 through the threaded engagement between the threaded ring 52 and the bottom surface of the connecting cylinder 51. During exhaust through exhaust pipe 3, the gas pushes the anti-backflow plate 6 up. Guided by sliding column 56, the anti-backflow plate 6 rises. When the gas exhaust speed is too fast, the anti-backflow plate 6 rises too high. The sliding seat drives the guide plate 55 to push the connecting cylinder 51 along the guide cylinder. The elastic spring 53 is in a compressed state. After exhaust, the anti-backflow plate 6 moves down quickly due to the elastic action of the elastic spring 53 and the gravity of the anti-backflow plate 6, thereby resetting the anti-backflow plate 6 and sealing the end of exhaust pipe 3. This prevents external dust and gas from entering the deaerator body 1 through exhaust pipe 3, reducing the impact of dust and gas on the deaerator body 1.

[0029] The advantages of this application are: 1. The automatic exhaust device of this type of deaerator has a novel design and simple structure. The anti-backflow plate can quickly reset and block the channel to prevent external air and impurities from flowing back into the deaerator body, thus preventing pollution of the deoxygenated water, ensuring stable deoxygenation efficiency, reducing manual intervention, and lowering operating costs. The replacement components are detachably connected to the exhaust pipe via threads, and can be disassembled as a whole in case of failure, facilitating quick replacement of aging elastic components, anti-backflow plates, and other parts, and shortening downtime for maintenance.

[0030] The circuits, electronic components, and modules involved are all existing technologies, which can be fully implemented by those skilled in the art, and need not be elaborated upon. The content protected by this application does not involve any improvement to the software and methods.

[0031] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
