[0029] like Figure 1-Figure 7As shown, the present invention provides the following technical solutions: a red coke feeding buffer mechanism for a dry quenching furnace, comprising a feeding pipe section 1 and a feeding pipe section 2, wherein a cover body 3 is fixedly connected between the feeding pipe section 1 and the feeding pipe section 2, a cylinder body 4 is rotatably connected to the cover body 3 through a connecting assembly, a plurality of swing assemblies are rotatably embedded in the inner wall of the cylinder body 4, an obliquely arranged orifice plate 8 is fixedly connected to the output end of the swing assembly, a plurality of orifice plates 8 are fitted on the two inner side walls of the cylinder body 4 and staggered from bottom to top, a motor 12 is fixedly connected to the bottom end of one of the swing assemblies, a gear 13 is fixedly connected to the output end of the motor 12, a gear 13 is meshed with a gear ring 14, and the gear ring 14 is fixedly sleeved on the outer wall of the cylinder body 4 The output end of the rotating motor 12 drives the gear 13 to rotate through the gear ring 14 to drive the cylinder 4 to rotate. The cylinder 4 drives the orifice plate 8 to rotate through the swing assembly, and the swing assembly drives the orifice plate 8 to swing. An inclined rod 16 is provided in the swing assembly for sliding. One end of the inclined rod 16 penetrates into the cylinder 4 and a plurality of cone rods 17 are fixedly connected to the top surface. The top end of the cone rod 17 passes through the orifice plate 8 and is slidably connected thereto. The other end of the inclined rod 16 penetrates into the cover body 3 and can be penetrated between two adjacent protrusions 18. The protrusion 18 is fixed in the swing assembly. The protrusion 18 can push the rotating inclined rod 16 to move with a longitudinal amplitude. The rotating inclined rod 16 can drive the cone rod 17 to move.

[0030] Please combine Figure 1 As shown, during the use process, the coke tank trolley filled with red coke is pulled by the electric locomotive to the bottom of the coke tank lifting derrick, the coke tank is lifted by the coke tank hoist and sent to the top of the dry quenching furnace, and the coke is sequentially loaded into the dry quenching furnace along the first section 1 of the feed pipe and the second section 2 of the feed pipe through the loading device on the top of the dry quenching furnace to exchange heat with the inert gas, the red coke falls onto the orifice plate 8 along the first section 1 of the feed pipe, and then falls along multiple orifice plates 8 in sequence, the controller is operated to make the motor 12 start working, the output end of the motor 12 drives the gear 13 to rotate, the gear 13 drives the gear ring 14 to rotate, the gear ring 14 drives the cylinder 4 to rotate, the cylinder 4 drives the orifice plate 8 to rotate through the swing assembly, and the orifice plate 8 drives The red coke that falls to the top surface rotates, so that the red coke on the top surface of the orifice plate 8 receives the resistance of centrifugal force, reducing the flow speed of the red coke on the top surface of the orifice plate 8, thereby extending the contact time with the inert gas and improving the heat exchange effect. The cylinder 4 drives the swing component to rotate, and the swing component drives the orifice plate 8 to swing longitudinally to lift the red coke on its top surface, reducing the accumulation of red coke. The swing component drives the inclined rod 16 to rotate, and the multiple protrusions 18 push the inclined rod 16 to move in turn. The inclined rod 16 drives the conical rod 17 to move longitudinally to separate the adhered red coke, thereby expanding the contact area between the red coke and the inert gas and improving the heat exchange efficiency. The falling red coke then flows along the second section 2 of the feed pipe.

[0031] The top surface of the orifice plate 8 is a corrugated surface and the radius of the corrugation gradually increases along the direction close to the center of the cylinder 4, extending the flow path of the red coke on the top surface of the orifice plate 8, thereby extending the contact time between the red coke and the inert gas and improving the heat exchange efficiency.

[0032] The angle between the plane where the top surface of the orifice plate 8 is located and the horizontal plane is in the range of 15°-30°, which increases the friction between the orifice plate 8 and the red coke and reduces the flow velocity at the top surface of the orifice plate 8.

[0033] Please combine Figure 1 As shown, an embodiment of the connection assembly includes a plurality of sliders 5 , which are evenly fixed on the top and bottom surfaces of the cylinder 4 , and the sliders 5 are slidably arranged in the slide grooves 6 , which are opened on the inner surface of the cover body 3 .

[0034] Please combine Figure 1 As shown, during use, when the cylinder 4 rotates, the cylinder 4 drives the slider 5 to rotate in the slide groove 6. The arrangement of the multiple sliders 5 and the slide groove 6 plays a role in positioning the cylinder 4, ensuring the normal rotation of the cylinder 4.

[0035] Please combine Figure 1 , Figure 6 , Figure 7 As shown, an embodiment of a swing assembly, the swing assembly includes multiple groups of rotating blocks 7 rotatably embedded in a cylinder 4, each group of rotating blocks 7 is composed of multiple rotating blocks 7, the multiple groups of rotating blocks 7 are not in the same horizontal plane, the side walls of each group of rotating blocks 7 are fixedly connected to the side walls of a hole plate 8, a lever 9 is fixedly connected to the surface of the rotating block 7, the lever 9 can be slidably arranged in multiple grooves 11, multiple grooves 11 are provided on the inner top surface of an arc-shaped slide rail 10, a motor 12 is fixedly connected to the bottom surface of one of the arc-shaped slide rails 10, the arc-shaped slide rail 10 is fixed to the inner wall of the cover body 3, a protrusion 18 is fixedly connected to the inner bottom surface of the arc-shaped slide rail 10, a through groove 15 is provided through the side wall of the rotating block 7, and a diagonal rod 16 is slidably arranged in the through groove 15.

[0036] Please combine Figure 1As shown, during use, when the cylinder 4 rotates, the cylinder 4 drives the rotating block 7 to rotate, and the rotating block 7 drives the orifice plate 8 to rotate to generate centrifugal force to generate resistance to the red coke on the top surface of the orifice plate 8, and the rotating block 7 drives the lever 9 to rotate between multiple grooves 11, and the arc-shaped slide rail 10 presses the lever 9 to swing, and the lever 9 drives the rotating block 7 to swing, and the rotating block 7 drives the orifice plate 8 to swing to lift the red coke on its top surface, so that the red coke is separated, the contact area between the red coke and the inert gas is increased, and the heat exchange efficiency is improved. When the lever 9 rotates into the groove 11, it falls to the orifice plate 8 at this time. The red coke on the surface pushes the orifice plate 8 to swing and reset due to gravity. The orifice plate 8 drives the lever 9 to swing and reset through the rotating block 7. The rotating block 7 drives the inclined rod 16 to rotate and pass through multiple protrusions 18 in sequence. Multiple protrusions 18 push the inclined rod 16 to move longitudinally in the through groove 15 in sequence. The inclined rod 16 drives the cone rod 17 to move and crush the red coke, increasing the contact area between the red coke and the inert gas, thereby increasing the heat exchange efficiency. When the inclined rod 16 separates from the protrusion 18, the red coke will push the cone rod 17 to move and reset, and the cone rod 17 drives the inclined rod 16 to move and reset.

[0037] Multiple protrusions 18 and multiple grooves 11 correspond to each other one by one and the corresponding protrusions 18 and grooves 11 are in the same vertical plane, realizing the alternating movement of the arc slide rail 10 pushing the lever 9 and the protrusions 18 pushing the inclined rod 16, thereby realizing the alternating movement of the orifice plate 8 swinging and the cone rod 17 longitudinally moving.

[0038] The top surface of the lever 9 is an outwardly convex arc surface, which facilitates the top end of the lever 9 to contact the surface of the arc-shaped slide rail 10 and the arc-shaped slide rail 10 to push the lever 9 to move.

[0039] The end face away from the orifice plate 8 is hinged with a lifting plate 19, which is in an inverted V shape. The bottom surface of the lifting plate 19 fits with one end of the inclined rod 16. When the protrusion 18 pushes the inclined rod 16 to move upward, the inclined rod 16 pushes the lifting plate 19 to move, and the red coke flowing along the lifting plate 19 is lifted, thereby increasing the contact area between the red coke and the inert gas.

[0040] A blanking plate 20 is fixedly connected to the inner wall of the cover body 3, and the bottom end of the blanking plate 20 is arranged in the second section 2 of the feed pipe.

A plurality of exhaust holes are opened on the surface of the blanking plate 20.

[0041] Please combine Figure 1As shown, during use, the red coke flows along the bottom lifting plate 19 to the blanking plate 20, and then slides along the top surface of the blanking plate 20. The lifting plate 19 rotating along the orifice plate 8 discharges the red coke on its surface to the top surface of the blanking plate 20 in sequence, and then falls along the top surface of the blanking plate 20. The top surface of the blanking plate 20 is an inclined surface, and the inclination angle of the inclined surface gradually increases along the rotation direction of the orifice plate 8, thereby changing the flow speed of the red coke at different positions on the top surface of the blanking plate 20, thereby achieving uniform falling of the red coke.

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.
