Description

Technical Field

[0001] The utility model relates to the technical field of boiler soot blowers, in particular to a leakage detection device for a boiler soot blower. Background Technique

[0002] The boiler soot blower removes the ash deposited on the heating surface of the boiler through specific technical means such as sound waves, infrasound waves, steam, etc., so as to restore the heat transfer efficiency of the boiler, reduce the reduction of thermal efficiency and potential safety hazards caused by ash deposition. When the boiler soot blower is in use, it is necessary to detect its leakage, which can ensure the safe operation of the unit.

[0003] The Chinese patent discloses a leakage detection device for a boiler soot blower (publication number CN221077921U). A temperature detector is installed at the connection between the steam inner pipe and the lifting valve to monitor the wall temperature of the steam inner pipe behind the lifting valve. The temperature detector is connected to the controller through a cable. The operator can timely discover equipment abnormalities according to the temperature parameters obtained by the controller and take corresponding measures for treatment, so as to effectively monitor whether the soot blower leaks.

[0004] However, most of the existing leakage detection methods for boiler soot blowers are detected by temperature detectors. The height of the temperature detector is fixed, resulting in the inability to adjust the position, which affects the purpose of efficient detection of the boiler soot blower. For example, in the above-mentioned comparative document, it adopts a fixed temperature detector detection method. In actual application, when the position of the temperature detector is fixed and it cannot extend into the interior of the steam inner cylinder, it will affect its detection effect on the boiler soot blower. Therefore, those skilled in the art provide a leakage detection device for a boiler soot blower to solve the problems raised in the above background technique. Content of the Utility Model

[0020] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0021] Please refer to Figures 1-4 , the present invention provides a technical solution for a leakage detection device for a boiler soot blower: including: an inner steam pipe 1 and an installation cylinder 11 arranged on the upper surface of the inner steam pipe 1. The upper surface of the installation cylinder 11 is embedded with a detection cylinder 2. A limit rod 3 penetrates through the outside of the detection cylinder 2. A limit hole 31 is opened inside the installation cylinder 11. A sealing ring 22 is also arranged above the limit rod 3 on the outside of the detection cylinder 2. And a connection plate 21 is fixedly installed at the upper end of the detection cylinder 2. A rotating rod 4 penetrates through the upper surface of the connection plate 21. The lower end of the rotating rod 4 is provided with a lifting plate 41 inside the detection cylinder 2. Two temperature detectors 43 are symmetrically arranged on the lower surface of the lifting plate 41. This setting can achieve the purpose of installing the detection cylinder 2 and the installation cylinder 11 by embedding the limit rod 3 into the limit hole 31, and the rotation of the rotating rod 4 can make the lifting plate 41 lift and lower to adjust the height of the temperature detector 43, so as to facilitate its purpose of detecting the leakage of the boiler soot blower.

[0022] As Figure 4 shown, two limit rods 3 are symmetrically arranged on the outside of the detection cylinder 2, and one end of the limit rod 3 is embedded inside the limit hole 31. A fixed groove 34 is also opened inside the detection cylinder 2. One end of the limit rod 3 is connected with a limit plate 32 inside the fixed groove 34. An electric push rod 33 is also installed inside the fixed groove 34. The telescopic end of the electric push rod 33 is connected to one side of the limit plate 32. This setting can make one end of the limit rod 3 be embedded into the limit hole 31 by using the electric push rod 33, and then the purpose of connecting the installation cylinder 11 and the detection cylinder 2 can be achieved.

[0023] As Figure 2 and Figure 3As shown in the figure, a bearing 42 is installed at the middle position of the upper surface of the lifting plate 41. The lower end of the rotating rod 4 is embedded inside the bearing 42 and is rotatably connected to the bearing 42. A rotating hole 211 is provided on the upper surface of the connecting plate 21. External threads are provided on the outside of the rotating rod 4, and internal threads are provided inside the rotating hole 211. Guide rails 44 are symmetrically arranged on the outside of the lifting plate 41. Guide grooves 23 that slide with the guide rails 44 are provided on the inside of the detection cylinder 2. This setting utilizes the threaded connection of the rotating rod 4 inside the rotating hole 211, so that the lifting plate 41 can be lifted or lowered. That is, the guide rails 44 move in a guiding manner inside the guide grooves 23, and thus the position of the temperature detector 43 on the lower surface of the lifting plate 41 can be adjusted to facilitate the leakage detection work.

[0024] The working principle of the present utility model is as follows: When the boiler soot blower leakage detection device of the present utility model is in use, first, the detection cylinder 2 is installed inside the installation cylinder 11 provided on the steam inner pipe 1. During installation, the detection cylinder 2 can be embedded into the installation cylinder 11 from top to bottom and limited by the connecting plate 21. After installation, the electric push rod 33 inside the fixing groove 34 can be started to work. In this way, one end of the limiting rod 3 will be embedded into the limiting hole 31, and thus the purpose of connecting the installation cylinder 11 and the detection cylinder 2 can be achieved. The sealing performance of the installation of the detection cylinder 2 can be improved by the sealing ring 22 outside the detection cylinder 2. At the same time, the rotating rod 4 is rotated, that is, the rotating rod 4 rotates threadedly inside the rotating hole 211, so that the lifting plate 41 can be lifted or lowered. That is, the guide rails 44 move in a guiding manner inside the guide grooves 23, and thus the position of the temperature detector 43 on the lower surface of the lifting plate 41 can be adjusted to facilitate the leakage detection work of the boiler soot blower, and the practicability is good.

[0025] The above are only the preferred embodiments of the present utility model.
