Description

Technical Field

[0001] The utility model relates to the technical field of biomass hot blast furnaces, in particular to a ash cleaning port of a biomass hot blast furnace. Background Art

[0002] In the operation and maintenance process of biomass hot air furnace, the design of the cleaning port plays a pivotal role. It has a direct impact on the cleanliness and ventilation effect of the furnace, and is more related to the safety of operators and the continuous service life of the equipment. Figure 1 As shown, a cover body is usually provided which is close thereto and is fastened by a plurality of bolts. When performing dust removal operations, the staff need to dismantle these bolts one by one to remove the cover body, which is not only cumbersome to operate, but also inefficient.

[0003] More importantly, the cleaning work is often carried out after the biomass hot air furnace completes the hot air transfer, and the shell near the cleaning port still maintains a high temperature. When the staff removes the cover, they must wear heat-insulating gloves to prevent burns, which undoubtedly increases the difficulty and complexity of the operation. In order to solve this series of problems, we proposed a biomass hot air furnace cleaning port, which aims to simplify the cleaning process, improve work efficiency, and maximize the safety of operators, thereby effectively extending the service life of the equipment. Utility Model Content

[0004] In view of the problems existing in the above-mentioned prior art, the utility model provides a biomass hot air furnace cleaning port, simplifies the cleaning process, improves work efficiency, and maximizes the safety of operators, thereby effectively extending the service life of the equipment.

[0005] In order to achieve the above-mentioned purpose, the biomass hot blast furnace cleaning port adopted by the utility model comprises a hot blast furnace body, the number of the said cleaning port bodies is three, the hot blast furnace body has a cleaning port body, an extension part extending outward along the cleaning port body and having a refractory pad, a ring-shaped part is sleeved in the middle of the said extension part, a ventilation path connecting the inner cavity of the hot blast furnace with the outside air is arranged inside the said extension part, a cover body is arranged at the outer end of the said extension part, a protrusion is fixed on the outer surface of the cover body, a fixing hole is opened on the said protrusion, a baffle is fixed in the middle of the said extension part, the baffle and the extension part are welded, a fixing block is arranged on the baffle, and a locking hole is arranged on the fixing block coaxially with the fixing hole, a locking rod passes through the locking hole and the fixing hole and is fixed in the locking hole, and the above-mentioned locking rod and the locking hole are threadedly matched, the rotating wheel is installed on the locking rod, and the rotating action of the rotating wheel synchronously drives the locking rod to rotate.

[0006] The above structure significantly improves the structural strength of the cleaning port by adding extensions and annular parts. At the same time, by increasing the distance between the cover and the cleaning port body, the risk of workers coming into contact with the high-temperature cleaning port when disassembling the cover is effectively reduced, thereby preventing possible scalding accidents. In addition, the use of a single rotating locking rod instead of the traditional bolt fixing method not only simplifies the operating steps, but also significantly improves the efficiency of disassembly and installation. In addition, the design of the baffle avoids direct opening on the surface of the hot air furnace, ensuring the appearance integrity of the hot air furnace.

[0007] As a further optimization of the above scheme, the fixed block includes a fixed part fixed on the baffle, a removable locking part is provided inside the fixed part, the inner surface of the locking part is provided with a first internal thread that cooperates with the locking rod thread, a connecting section is provided on the side of the locking part away from the fixed part, the accommodating part is provided with an accommodating groove that is plug-in compatible with the connecting section, the outer surface of the accommodating part is provided with an external thread, and the inner surface of the fixed part is provided with a second internal thread that is a matching structure with the external thread, the connecting section is annularly arranged with a plurality of elastic strip blocks along the outer edge, and a semicircular embedded block is fixed to the protruding end of the strip block, a semicircular hole that is embedded and matched with the embedded block is provided on the inner wall of the above-mentioned accommodating groove, and the diameter of the accommodating groove decreases successively along the deepening path of the connecting section.

[0008] The above structure ensures the stability of the structure and facilitates maintenance and replacement by designing the fixing block into a split structure. Specifically, the strip block on the connecting section cooperates with the receiving groove, and the embedded block cooperates with the semicircular hole to enhance the stability of the connection. In addition, the diameter of the receiving groove is larger than the diameter of the connecting section. The plug-in design makes the connection tighter and further enhances the connection effect of the locking part and the receiving part.

[0009] The biomass hot air furnace cleaning port of the utility model has the following beneficial effects:

[0010] 1. The biomass hot air furnace cleaning port of the utility model significantly improves the structural strength of the cleaning port by adding extension and annular parts. At the same time, by increasing the distance between the cover and the cleaning port body, the risk of workers coming into contact with the high-temperature cleaning port when disassembling the cover is effectively reduced, thereby preventing possible scalding accidents. In addition, a single rotating locking rod is used to replace the traditional bolt fixing method, which not only simplifies the operating steps, but also significantly improves the efficiency of disassembly and installation. In addition, the design of the baffle avoids direct opening on the surface of the hot air furnace, ensuring the appearance integrity of the hot air furnace.
