DETAILED DESCRIPTION

[0050] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0051] Example 1

[0052] A device for neatly stacking steel chip cakes comprises a lifting cylinder 3, the interior of the lifting cylinder 3 is used to place stacked steel chip cakes 2, the bottom of the lifting cylinder 3 is provided with an opening, the lower end of the lifting cylinder 3 is connected with an iris opening and closing mechanism 1, when the iris opening and closing mechanism 1 is opened, the steel chip cakes 2 can enter and exit through the bottom of the lifting cylinder 3, and when the iris opening and closing mechanism 1 is closed, the steel chip cakes 2 cannot enter and exit the bottom of the lifting cylinder 3.

[0053] in:

[0054] A lifting ring 31 for lifting is usually provided on the top of the lifting cylinder 3. In order to conveniently observe whether there are steel chip pressed cakes 2 in the lifting cylinder 3 and the number of steel chip pressed cakes 2, an observation port 32 can be optionally provided on the lifting cylinder 3.

[0055] The iris opening and closing mechanism 1 includes a bottom ring 11, which can be connected to the bottom of the lifting cylinder 3 by a connecting column 112. A sliding ring groove 111 is provided on the bottom ring 11, and a sliding ring 12 is slidably provided in the sliding ring groove 111. A plurality of blades 13 are rotatably connected to the sliding ring 12. A sliding groove 131 is provided on the blade 13, and a fixed column is slidably connected in the sliding groove 131. The fixed column is connected between the sliding ring groove 111 and the inner wall of the bottom ring 11. When the sliding ring 12 rotates clockwise, it can drive the blade 13 to rotate. Due to the restrictions of the sliding groove 131 and the fixed column, the end of the blade 13 will also rotate toward the center of the bottom ring 11. At this time, the iris opening and closing mechanism 1 is in a closed state;

[0056] When the sliding ring 12 rotates counterclockwise, it can drive the blade 13 to rotate. Due to the restrictions of the sliding groove 131 and the fixing column, the end of the blade 13 will also rotate toward the outer edge of the bottom ring 11. At this time, the iris opening and closing mechanism 1 is in an open state.

[0057] The shapes of the blades 13 are consistent or inconsistent. The present invention does not limit the requirement that the shapes of the blades 13 are consistent. The dimensions should meet the following requirements, including but not limited to:

[0058] 1. The blade 13 can make the lifting tube 3 enter the smelting furnace 5 at any rotation angle;

[0059] 2. When the blade 13 is in the closed position, it can prevent the steel chip cake 2 from falling out of the lifting cylinder 3.

[0060] When used with the support platform 4, the shape of the blade 13 includes an arc segment AB, an upper arc segment AC and a lower arc segment BC, the radius of the arc segment AB is a, the distance from the center of the arc segment AB to the blade end C is b, the sliding ring 12 is rotatably connected to the blade 13 through a rotating shaft, the diameter of the circle where the rotating shaft is located is d1, and the support platform 4 is used to support the stacked steel chip cakes 2. In order to prevent the top of the support platform 4 from affecting the closed state of the blades 13, the top diameter d4 of the support platform 4 is less than d1-b. The support platform 4 can raise the stacked steel chip cakes 2 and leave space for the blades 13 to support near the edge at the bottom of the steel chip cakes 2, which can reduce the impact during lifting and placement. The support platform 4 is usually placed at the bottom of the inner wall of the smelting furnace 5 and the stacking operation area of ​​the steel chip cakes 2. Note that when placed at the bottom of the inner wall of the smelting furnace 5, a material with stable properties should be selected and the shape should not affect the smelting process.

[0061] In order to facilitate the control of the iris opening and closing mechanism 1, it includes an iris control mechanism 6, an opening rope, a closing rope and an operating rod 121. One end of the operating rod 121 is connected to the sliding ring 12, and the other end extends to the outside of the iris opening and closing mechanism 1. The iris control mechanism 6 includes a closing pulley 61, an opening pulley 64, a closing sleeve 62, an opening sleeve 65, a closing pull ring 63, and an opening pull ring 66. The closing pulley 61 and the opening pulley 64 are rotatably connected to the outer wall of the lifting cylinder 3 or the bottom ring 11, and the closing sleeve 62 and the opening sleeve 65 are connected to the outer wall of the lifting cylinder 3.

[0062] One end of the opening rope is connected to the operating rod 121, and the other end passes through the opening pulley 64, passes through the opening sleeve 65, and is connected to the opening pull ring 66. When the opening pull ring 66 is pulled, the opening rope can drive the sliding ring 12 to rotate clockwise through the operating rod 121;

[0063] One end of the closing rope is connected to the operating rod 121, and the other end passes around the closing pulley 61, passes through the closing sleeve 62, and is connected to the closing pull ring 63. When the closing pull ring 63 is pulled, the opening rope can drive the sliding ring 12 to rotate counterclockwise through the operating rod 121.

[0064] The closing pull ring 63 and the opening pull ring 66 can be controlled by using a secondary hook or manually.

[0065] The method of using this embodiment is as follows:

[0066] S1: Lift the lifting cylinder 3;

[0067] S2: Open the iris opening and closing mechanism 1 at the bottom of the lifting cylinder 3;

[0068] S3: placing the stacked steel chip cake 2 on the support platform 4;
