Description

Technical Field

[0001] The utility model relates to the field of graphite electrode production equipment, in particular to a batching device for graphite electrode production. Background Art

[0002] A graphite electrode refers to a high-temperature-resistant graphite conductive material made of petroleum coke and pitch coke as aggregates and coal tar pitch as a binder through processes such as raw material calcination, crushing and grinding, batching, kneading, forming, roasting, impregnation, graphitization, and machining, which is called an artificial graphite electrode, simply referred to as a graphite electrode, to distinguish it from a natural graphite electrode prepared from natural graphite as the raw material. When the existing graphite electrodes are being batched, it is necessary to pour the raw materials in corresponding proportions into the mixing tank for kneading to facilitate the subsequent production processes.

[0003] After retrieval, Chinese Patent Publication No.: CN220478731U discloses a batching device for graphite electrode production, including a stirring tank. A motor is fixedly installed at the top of the stirring tank, and the output end of the motor is connected to an auger located inside the stirring tank. A stirring pipe is arranged outside the auger and inside the stirring tank. A plurality of support platforms are evenly distributed outside the stirring tank, and auxiliary material barrels are installed on the tops of the support platforms. A plurality of feed pipes are connected to the side wall of the stirring tank at equal intervals.

All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0032] Referring to Figure 1 , an embodiment provided by the present invention: A batching device for the production of graphite electrodes, including a bottom plate 1, a dust collection box 2 for collecting dust particles is fixedly connected to the top of the bottom plate 1, a feeding tank 3 arranged in an inclined state is fixedly connected to the top of the dust collection box 2, a conveying mechanism is arranged inside the feeding tank 3, a mixing box 4 for preliminarily mixing raw materials and batching is fixedly connected to the top of the feeding tank 3, a batching box 5 for extruding and crushing raw materials and batching is fixedly connected to the top of the mixing box 4, to prevent large-volume raw materials and batching that agglomerate during storage from entering the inside of the mixing box 4 and the feeding tank 3, reducing the subsequent processing quality. A feeding pipe 6 for facilitating feeding is fixedly connected to the top of the batching box 5, a stepping motor 7 is fixedly connected to the top of the batching box 5, and an extrusion mechanism is arranged inside the batching box 5.

[0033] Referring to Figure 2 , Figure 3 , the extrusion mechanism includes a rotating shaft 8, the rotating shaft 8 is fixedly installed at the bottom of the output shaft of the stepping motor 7. The stepping motor 7 can accurately control the rotation angle of its output shaft, facilitating the adjustment of the rotation speed and rotation angle of its rotating shaft, and can be adjusted accordingly according to different requirements, improving the accuracy of control. A first rotating block 9 is fixedly connected to the bottom of the rotating shaft 8, the bottom of the first rotating block 9 contacts a second rotating block 10, the second rotating block 10 is slidably installed on the inner wall of the batching box 5, the sliding direction of the second rotating block 10 is the axial direction of the batching box 5, a spring 11 is fixedly connected to the bottom of the second rotating block 10, by setting the spring 11 to apply an upward elastic force to the second rotating block 10, a limiting ring 12 is fixedly connected to the bottom of the spring 11, the limiting ring 12 plays a limiting role to prevent the second rotating block 10 and the spring 11 from falling off, and the limiting ring 12 is fixedly installed on the inner wall of the batching box 5.

[0034] Referring to Figure 3 , a convex block is arranged at the bottom of the first rotating block 9, a diversion hole 13 penetrating through the upper and lower sides of the first rotating block 9 is arranged on the surface of the first rotating block 9, the diversion hole 13 is used to facilitate the passage of the graphite electrode raw material mixture, a protrusion matching with the convex block of the first rotating block 9 is arranged at the top of the second rotating block 10, for extruding and crushing the graphite electrode raw material mixture, improving the processing quality, and the diversion hole 13 is arranged on the surface of the second rotating block 10.

[0035] Referring to Figure 1 ,Figure 4 , Figure 5 , the conveying mechanism includes a servo motor 14, which can precisely control the rotation angle of its output shaft. The servo motor 14 is fixedly installed on the left side of the material conveying tank 3. The right side of the output shaft of the servo motor 14 is fixedly connected with a rotating rod 15. The rotating rod 15 is rotatably installed on the inner wall of the material conveying tank 3 through a bushing. The circumferential surface of the rotating rod 15 is fixedly connected with a spiral conveying blade 16. When the spiral conveying blade 16 rotates, it conveys the graphite electrode raw material from the right side of the material conveying tank 3 to the left side of the material conveying tank 3. The bottom of the material conveying tank 3 is fixedly connected with a discharge pipe 17 for discharging the graphite electrode raw material after batching, which facilitates the entry into the next process. The bottom of the material conveying tank 3 is fixedly connected with a filter plate 18 for filtering dust particles inside the graphite electrode raw material, which improves the purity of the graphite electrode raw material and thus improves the product quality. The discharge pipe 17 is arranged on the left side of the bottom of the material conveying tank 3, and the filter plate 18 is arranged at the center of the bottom of the material conveying tank 3.

[0036] Refer to Figure 1 , Figure 4 , a collection box 19 for facilitating the centralized treatment of dust particles is arranged inside the collection box 2.

The collection box 2 is arranged in an inclined state. The mixing box 4 is arranged on the top right side of the collection box 2.

[0037] Working principle: When in use, graphite electrode raw material is put into the feeding pipe 6. After the graphite electrode raw material enters the inside of the batching box 5, it falls above the rotating block one 9, and then falls between the rotating block one 9 and the rotating block two 10 through the diversion hole 13. Then, the power of the stepping motor 7 is started. The stepping motor 7 works to drive the rotating shaft 8 to rotate. The rotating shaft 8 rotates to drive the rotating block one 9 to rotate. The rotation of the rotating block one 9 causes the convex block of the rotating block one 9 to squeeze the protrusion of the rotating block two 10, thereby causing the rotating block two 10 to displace downward against the elastic force of the spring 11. As the rotating block one 9 rotates, the graphite electrode raw material between the rotating block one 9 and the rotating block two 10 is squeezed and crushed by the rotating block one 9 and the rotating block two 10, so as to crush some agglomerated graphite electrode raw materials with larger volumes, and it falls into the inside of the material conveying tank 3 through the mixing box 4.

[0038] By starting the servo motor 14, the servo motor 14 works to drive the rotating rod 15 to rotate. The rotating rod 15 rotates to drive the spiral conveying blade 16 to rotate, and then conveys the graphite electrode raw material on the right side of the material conveying tank 3 to the left side of the material conveying tank 3. During the displacement of the graphite electrode raw material, it will pass through the screening of the filter plate 18, so that some dust impurities enter the collection box 19 inside the collection box 2. The screened graphite electrode raw material will be discharged from the discharge pipe 17, so that the batch-mixed graphite electrode raw material enters the next process.

[0039] Finally, it should be noted that the above are only the preferred embodiments of the present utility model and are not used to limit the present utility model.
