Description

Technical Field

[0001] The utility model belongs to the technical field of fire poker holes, and in particular relates to a sealing device for a fire poker hole of a furnace. Background Art

[0002] In the production process of industrial kilns such as lime kilns (such as Melz kilns), blast furnaces, and vertical furnaces, the inside of the kiln is in a high temperature state, and the calcined materials and smoke move in the kiln. At the same time, the various process parameters inside the kiln are constantly changing. Therefore, it is necessary to set an observation hole (commonly known as a fire-stirring hole) on the kiln shell to observe the production situation inside the kiln at any time. For lime kilns, if the material in the kiln is not moving smoothly and smoke accumulates, the hole is also used for cleaning to avoid the material in the kiln from hardening.

[0003] The fire-poking hole is a device used to check the combustion conditions in the kiln, clean and maintain the refractory structure inside the kiln. It is closed in production and opened in maintenance and repair. The fire-poking hole cover needs to have the dual functions of fire-resistant insulation and sealing.

[0004] At present, the fire-poker hole cover plates are all sealed with heat-resistant packing, which is not only relatively troublesome to install, but also has a low rate of packing reuse, which is not conducive to saving sealing costs. In addition, the seal is relatively easy to fail, resulting in a loose seal of the fire-poker hole. If the fire-poker hole is not sealed tightly, a small amount of hot smoke will leak out through the gap of the cover plate, causing local fire, thus bringing serious safety hazards.

[0015] The utility model is further described below in conjunction with the accompanying drawings and embodiments.

[0016] In order to more clearly illustrate the technical solutions in the embodiments of the present application, the drawings required for use in the embodiments or the description of the prior art will be briefly introduced below. Obviously, the drawings described below are only some embodiments of the present application. For ordinary technicians in this field, other drawings can be obtained based on these drawings without paying any creative work.

[0017] Figure 1 It is a schematic diagram of a preferred embodiment of the utility model. DETAILED DESCRIPTION

[0018] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present application more clearly understood, the present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0019] It should be noted that when an element is referred to as being "fixed to" or "disposed on" another element, it can be directly on the other element or indirectly on the other element. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or indirectly connected to the other element.

[0020] 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 drawings, and are only for the convenience of describing the present 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 should not be understood as a limitation on the present application.

[0021] In addition, the terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. 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.

[0022] like Figure 1 As shown, the utility model discloses a furnace poker hole sealing device, including a poker hole 7 and a sealing cover 1, a sealing groove is provided at the opening of the poker hole, an asbestos sealing strip 6 is filled in the sealing groove, and a leveling layer 5 is coated on the opening of the poker hole. In this embodiment, the leveling layer is a lime layer; it can be understood that: in order to facilitate the movement of the sealing cover, a handle 3 is provided on the sealing cover.

[0023] When sealing, place the asbestos sealing strip in the sealing groove, then apply lime to form a leveling layer to further strengthen the sealing, and then cover the cover. With the sealing form of the present application, on the one hand, the asbestos sealing strip can be long-lasting, durable, and reused, and the sealing material does not need to be replaced every time the fire-poking hole is opened, which is conducive to saving sealing costs. On the other hand, the addition of a leveling layer is conducive to improving the sealing performance.

[0024] As a further improvement to the above technical solution, the cross section of the sealing groove is square, the cross section of the asbestos sealing strip is also square, and the asbestos sealing strip is matched and embedded in the sealing groove. With this structural form, a vertically connected horizontal seal and vertical seal are formed, further improving the sealing performance.

[0025] As a further improvement to the above technical solution, the opening of the poker port forms a tapered hole 8, the sealing groove is provided on the wall of the tapered hole, and the sealing cover is integrally provided with a cone 2 that matches and fits with the tapered hole. With this structural form, a tapered surface seal is formed, further improving the sealing performance.

[0026] As a further improvement to the above technical solution, the sealing cover is provided with an extension 4, which further improves the sealing performance.

[0027] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the purpose and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
