Technical Field

[0001] The utility model relates to the technical field of hot blast stoves, in particular to a hot blast stove structure. Background Art

[0002] A hot air furnace is a device used to produce high-temperature hot air. It is commonly used in industrial fields for processes such as drying, baking and melting. The basic principle is that the high-temperature gas generated by the combustion of fuel is mixed with the air in the pipeline to form high-temperature hot air, which is then transported through the pipeline to the equipment that needs to be heated for heat exchange, and the excess heat is transferred to the material or project that needs to be heated, thereby achieving the heating effect.

[0003] Since the existing hot blast stove is large in size, it is necessary to use steel ropes and lifting ears on the hot blast stove and a crane to move the hot blast stove during transportation and movement. However, the lifting ears on the existing hot blast stove are all fixed in design. When it is necessary to connect the steel ropes and the lifting ears, the hot blast stove is large in size, so the staff need to use tools such as ladders to climb up to the hot blast stove for manual operation. There are safety hazards such as slipping and falling when working at heights. Utility Model Content

[0023] In order to facilitate understanding of the present application, the present application will be described more fully below with reference to the relevant drawings. Embodiments of the present application are provided in the drawings. However, the present application can be implemented in many different forms and is not limited to the embodiments described herein. On the contrary, the purpose of providing these embodiments is to make the disclosure of the present application more thorough and comprehensive.

[0024] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art to which this application belongs. The terms used herein in the specification of this application are only for the purpose of describing specific embodiments and are not intended to limit this application.

[0025] This embodiment provides a hot blast furnace structure, which is more conducive to the safe operation of steel rope binding by workers. Specifically, Figure 1-4 The invention comprises a furnace body 1 and a lifting ear assembly 3. A plurality of metal plates 2 are provided in a ring shape on the surface of the furnace body 1. A slide groove 21 is provided in a ring shape on the sides of the plurality of metal plates 2 close to each other. The lifting ear assembly 3 comprises a sliding plate 31 and a lifting ear body 32. The sliding plate 31 is arc-shaped and is arranged between the slide grooves 21 provided by the plurality of metal plates 2. The lifting ear body 32 is arranged on the surface of the sliding plate 31, so that the lifting ear assembly 3 can be adjusted between the plurality of metal plates 2, thereby facilitating the connection operation between the steel rope and the lifting ear body 32 on the ground, and the operation process is safer.

[0026] like Figure 1 , Figure 3 , Figure 4 and Figure 5As shown, in this embodiment, a plurality of grooves 22 are provided inside the metal plate 2, and the surface of the metal plate 2 and the corners near the grooves 22 are all rounded. Two openings 311 are respectively provided on the left and right sides of the sliding plate 31, and the distance between the two openings 311 on the same side is equal to the distance between the plurality of grooves 22. A spring 4 is provided in the opening 311, and a clamping member 5 is provided between the sliding plate 31 and the metal plate 2. The clamping member 5 includes a connecting plate 51, a protruding rod 52 and a clamping block 53. The clamping block 53 and the protruding rod 52 are respectively connected to the left and right sides of the connecting plate 51, and the end of the clamping block 53 away from the connecting plate 51 is designed as a semicircular structure, and one side of the connecting plate 51 contacts the surface of the spring 4. A threaded path is provided in the opening 311, and an external threaded tube 6 is provided in the opening 311 through the threaded path. A groove 2 531 is provided at the end of the block 53 away from the connecting plate 51, and a metal ball 7 is provided in the groove 2 531 which is in contact with the surface of the metal plate 2. The spring 4 is in a compressed state, and the two lifting ear bodies 32 respectively protrude to the outside of multiple metal plates 2, so that when the staff is sliding and adjusting the lifting ear assembly 3, the metal ball 7 can rotate with the sliding of the lifting ear assembly 3 until one end of the multiple clamping blocks 53 is respectively clamped into the groove 22 opened in the metal plate 2 under the rebound action of the spring 4, thereby achieving the restriction effect on the lifting ear assembly 3, and facilitating the staff to perform the connection operation between the steel rope and the lifting ear body 32.

[0027] like Figure 2-3 As shown, a rubber pad 8 is provided on the surface of the connecting plate 51, and loading and unloading ports 23 are opened through the surfaces of the multiple metal plates 2. The diameter of the loading and unloading ports 23 is larger than the diameter of the sliding plate 31, so that the ear assembly 3 can be disassembled separately from the metal plate 2, so that the ear assembly 3 can be repeatedly used on multiple hot air furnaces, saving manufacturing costs. At the same time, the rebound spring 4 and the rubber pad 8 can also be used to achieve a limiting effect on the external threaded tube 6, so as to avoid the external threaded tube 6 from loosening or falling off when the disassembled ear assembly 3 is moved.

[0028] When the hot blast furnace structure needs to be transported and moved, the staff can grab the protruding ear body 32 and apply pressure upward, so that the ear body 32 drives the sliding plate 31 to slide along the slide groove 21 opened in the metal plate 2. Since the metal ball 7 is in contact with the surface of the metal plate 2, the metal ball 7 rotates during the sliding process until the clamping block 53 corresponds to the groove 22 opened in the metal plate 2 and the spring 4 rebounds and engages with each other, so that the ear assembly 3 is clamped and restricted to a suitable position. Then the staff can use the steel rope to connect the adjusted ear body 32. After the operation is completed, the crane and other equipment can be used to apply pressure to the ear assembly 3 upward through the steel rope. During the pressure application process, the clamping block 53 is separated from the groove 22 opened in the metal plate 2, and the spring 4 contracts again until the ear assembly 3 slides to a position between multiple metal plates 2 and close to the top, and finally the hot blast furnace can be lifted and moved.

[0029] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
