Description

Technical Field

[0001] The present application relates to the technical field of boiler equipment, and in particular to an inspection hole sealing device. Background Art

[0002] During the operation of the boiler equipment, due to the large amount of boiler dust and the rapid adhesion of lumps, each shift is required to check the operation of the scraper and clean up the accumulated lumps in time to ensure the normal operation of the boiler equipment.

[0003] However, since the inspection holes need to be opened frequently, the sealing of the inspection holes will be damaged, and the threads of the push rod on the sealing plate will be damaged. This will cause serious dust leakage at the inspection holes when the shock wave is emitted or the amount of dust is large, resulting in a poor on-site production environment and difficulty in ground hygiene cleaning. A large amount of manpower and time are required for cleaning to ensure safe production.

[0004] The above-mentioned ash leakage problem at the inspection hole will lead to a decrease in production efficiency and at the same time there will be a major safety hazard in production. Utility Model Content

DETAILED DESCRIPTION

[0037] The following describes embodiments of the present application in more detail with reference to the accompanying drawings. Although the accompanying drawings illustrate embodiments of the present application, it should be understood that the present application can be implemented in various forms and should not be limited by the embodiments described herein. Rather, these embodiments are provided to make the present application more thorough and complete, and to fully convey the scope of the present application to those skilled in the art.

[0038] It should be understood that although the terms "first", "second", "third", etc. may be used in this application to describe various information, this information should not be limited to these terms. These terms are only used to distinguish information of the same type from each other. For example, without departing from the scope of this application, the first information may also be referred to as the second information, and similarly, the second information may also be referred to as the first information. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features. In the description of this application, the meaning of "plurality" is two or more, unless otherwise clearly and specifically defined.

[0039] In the description of this application, it should be understood that the terms "length", "width", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", etc., indicating the orientation or position relationship, are based on the orientation or position relationship shown in the accompanying drawings, and are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on this application.

[0040] Unless otherwise expressly specified or limited, terms such as "mounted," "connected," "connect," and "fixed" should be interpreted broadly. For example, they may refer to fixed or detachable connections, or integration; mechanical or electrical connections; direct or indirect connections through an intermediary; and internal communication between two components or interaction between two components. Those skilled in the art will understand the specific meanings of these terms in this application based on the specific circumstances.

[0041] Frequent opening of the inspection hole can damage the seal and the threads of the push rod on the sealing plate. This can cause serious dust leakage from the inspection hole during shock wave operation or when dust levels are high. This leads to a poor on-site production environment and difficulty in cleaning the ground, requiring a significant amount of manpower and time to clean to ensure safe production. The above-mentioned dust leakage problem at the inspection hole reduces production efficiency and poses a significant safety hazard.

[0042] In response to the above problems, an embodiment of the present application provides an inspection hole sealing device that can effectively seal the inspection hole of the boiler to ensure production efficiency and production safety.

[0043] The technical solutions of the embodiments of the present application are described in detail below with reference to the accompanying drawings.
