Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more clearly understood, the present invention will be further described in detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.
As shown in fig. 1-3, the utility model relates to a shaft furnace structure with a simulation funnel cap, which comprises a furnace body 11 and a funnel cap, wherein a converging cone cylinder is arranged below the inside of the furnace body, and the funnel cap is positioned at the upper position inside the converging cone cylinder; the blast cap comprises a blast cap sleeve 1, a support barrel 14 and a conical cap body 4; the top end of the hood sleeve 1 is provided with a circular truncated cone 2; the supporting cylinder is fixed on the circular truncated cone 2, wherein a concave table is arranged on the surface of the circular truncated cone 2, a groove matched with the concave table is arranged on the bottom surface of the supporting cylinder, the concave table and the groove are in contact with each other to form an occlusal surface 21, a plurality of layers of conical group edges 6 are arranged on the supporting cylinder, the conical group edges 6 are made of aluminum alloy plates, a partition plate 7 is arranged between the upper layer and the lower layer of the conical group edges 6, the partition plate and the group edges are made of the same material, and an air outlet hole 9 is formed in the area between the partition plates; the top end of the supporting cylinder is provided with an inner cone part 10, the inner cone part is of a conical structure formed by curling an aluminum alloy plate, the blast cap is fixed on the supporting cylinder through the inner cone part 10, and the inner cone part and the blast cap are directly fixed through rivets; a spacing gap exists between the position of the maximum outer diameter of the bottom end of the blast cap and the converging cone, the spacing is smaller than 1 m, and the ratio of the maximum outer diameter of the blast cap to the inner diameter of the kiln body is 1: 2; the circumference of the hood sleeve 1 is provided with an air door 3, an air channel 13 is arranged between the kiln body and the air door 3, the air channel 13 is connected with an air supply system, the air channel 13 penetrates through the confluence conical cylinder 12, and a sealing sleeve 15 is arranged at the position where the air channel 13 is contacted with the kiln body.
The bottom end of the cap sleeve is provided with a circular bottom edge 8.
