Technical Field
[0001] The utility model relates to the technical field of molded coke preparation, in particular to a double-roller forming machine for molded coke preparation. Background Art
[0002] Coke powder and fine coke powder are used as raw materials and a binder is added. After stirring and mixing, the mixture is pressed into balls by a roller forming machine to obtain spherical coke. Coke powder and fine coke powder are quantitatively fed in a ratio of 7:3 and lifted to the ground by a bucket elevator. Then they enter the first-level double-shaft mixing conveyor through a belt conveyor. The binder is quantitatively fed into the first-level double-shaft mixing conveyor through a binder bin at a ratio of 5%. The first-level double-shaft mixing conveyor stirs the materials and sends them to the second-level double-shaft mixing conveyor. The evenly mixed materials enter the quantitative feeding bin and then enter the roller forming machine for pressing and forming. The spherical coke is screened through a sifter, and the coke on the screen enters the dryer for drying.
[0003] After the material is pressed into ball shape by a double-roll forming machine, there will be residual material in the forming groove on the extrusion roller. As the extrusion roller rotates, the notch of the forming groove faces downward, and the material in the forming groove falls downward under its own gravity. The residual material falls into the screening device, thus affecting the screening effect of spherical coke. Utility Model Content

[0020] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.
[0021] Example 1
[0022] Reference Figure 1-4 The double-roll forming machine for preparing molded coke comprises a shell 1, the upper end of the shell 1 is connected with a feed hopper 2, two symmetrically arranged ball pressing rollers 3 are rotatably connected to the shell 1, each ball pressing roller 3 is provided with a plurality of forming grooves 4, a screening mechanism 5 is fixedly connected to the bottom end of the shell 1, both sides of the interior of the shell 1 are connected with an anti-drop mechanism 6 for preventing residual material in the forming grooves 4 from falling, a buffer guide plate 7 is fixedly connected to the shell 1, and the buffer guide plate 7 is located below the ball pressing roller 3;
[0023] The anti-drop mechanism 6 includes a baffle 61, which is fixedly connected to the shell 1 and is located below the ball pressing roller 3. The baffle 61 cooperates with the ball pressing roller 3. A scraper 62 is fixedly connected to one side of the baffle 61, and the scraper 62 contacts the ball pressing roller 3. The upper end of the scraper 62 is a pointed structure. A collecting box 63 is fixedly connected to one side of the baffle 61, and the collecting box 63 is located below the scraper 62.
[0024] Working process: the material is introduced into the shell 1 through the feed hopper 2, the material falls on the upper end of the ball pressing roller 3, and part of the material falls into the forming groove 4. After the two ball pressing rollers 3 rotate, the corresponding forming grooves 4 cooperate to extrude the material to produce spherical coke. After the two corresponding forming grooves 4 are separated, the formed spherical coke falls on the buffer guide plate 7 under its own gravity. The buffer guide plate 7 buffers and guides the spherical coke. After buffering, the spherical coke falls into the screening mechanism 5. The screening mechanism 5 screens the spherical coke and removes the unqualified spherical coke.
[0025] When the forming groove 4 rotates to the bottom end, the notch of the forming groove 4 faces downward, and the forming groove 4 contacts the baffle 61. The baffle 61 blocks the notch of the forming groove 4 to prevent the residual material in the forming groove 4 from falling. At the same time, the ball pressing roller 3 contacts the scraper 62 during rotation. The scraper 62 scrapes the residual material on the outer wall of the ball pressing roller 3, and the scraped material falls into the collecting box 63. The collecting box 63 collects the scraped material to prevent the residual material from falling into the screening mechanism 5, thereby not affecting the screening of spherical coke.

The spherical coke falls into the fixed frame 51 after being guided by the buffer guide plate 7. The spherical coke in the fixed frame 51 rolls along the length direction of the fixed frame 51, and the spherical coke rolls on the filter screen 52. The broken spherical coke is screened out by the filter screen 52, and the complete spherical coke is released from the discharge port 53.
