Description

Technical Field

[0001] The utility model relates to the technical field of carbon product equipment, in particular to a carbon product mixing and kneading device with an asphalt spraying device. Background Art

[0002] Kneading pots are primarily used for carbon products such as electrode paste, anode paste, and graphitized electrodes. They are made from petroleum coke, anthracite, and metallurgical coke as the primary raw materials, with coal tar pitch as the binder. Some are used as electrode paste for conductive electrodes in various continuous self-baking electric furnaces; others as anode paste for conductive anodes in continuous self-baking aluminum tanks; and still others as filler for blast furnace masonry and as coarse and fine joint paste for refractory slurries. While self-baking carbon blocks for blast furnaces have different uses, their production process is similar to that of paste products and they are therefore tentatively classified as such.

[0003] At present, the addition of asphalt to the kneading pot in the molding workshop of the anode production line of domestic carbon plants is mainly done by gravity flow in the pipeline. The asphalt is simply added to the kneading pot through the pipeline. The contact area between the asphalt and the raw materials in the kneading pot is small, which makes it more difficult to stir and mix. Secondly, there is a lack of heating and insulation structure for the transported asphalt, which easily causes the asphalt to cool down, affecting the stability of transportation and stirring and mixing, and therefore cannot meet the needs of users.

[0004] To address the above-mentioned technical issues, the utility model patent CN213160641U discloses an asphalt spray filling system for a kneading pot. An asphalt pump pumps asphalt from the asphalt tank through a connecting pipe and a liquid inlet pipe into a spray pipe, where it is sprayed through a spray head onto the raw materials in the kneading pot. A driving motor then rotates the stirring roller to stir and mix. However, in this technical solution, because the asphalt is sprayed along the upper surface of the raw materials in the kneading pot, the asphalt tends to concentrate excessively in the upper layer of the raw materials, making it difficult to achieve uniform mixing of the raw materials and asphalt in a short period of time. The only option is to increase the rotation time of the stirring roller to increase the number of stirring cycles. This not only increases mixing time but also energy consumption.

DETAILED DESCRIPTION

[0027] The following will be combined with the accompanying 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 embodiments described 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 making creative efforts are within the scope of protection of the present invention.

[0028] In the description of the present invention, it should be understood that the terms "upper", "middle", "outer", "inner", "lower" and the like indicating directions or positional relationships are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific direction, be constructed and operated in a specific direction, and therefore should not be understood as limiting the present invention.

[0029] Please see Figures 1 to 6 The utility model provides a carbon product kneading device with an asphalt spraying device, including a shell 01, an asphalt spraying device 02, and a mixing device 03; the mixing device 03 includes a first transmission shaft 31, a second transmission shaft 32, and a stirring assembly 33; the first transmission shaft 31 and the second transmission shaft 32 are rotatably arranged in the shell 01 along the length direction of the shell 01, the first transmission shaft 31 is located directly above the second transmission shaft 32, and the stirring assemblies 33 are axially equidistantly arranged on the first transmission shaft 31 and the second transmission shaft 32, and the stirring assemblies 33 installed on the first transmission shaft 31 and the stirring assemblies 33 installed on the second transmission shaft 32 are staggered. The first transmission shaft 31 and the second transmission shaft 32 are both driven by a variable frequency motor externally mounted on the outside of the shell 01. The first transmission shaft 31 and the second transmission shaft 32 can rotate in the same direction or in opposite directions. For example, when the first transmission shaft 31 rotates counterclockwise, the second transmission shaft 32 rotates clockwise. This allows the raw materials and asphalt to form opposite cross-contact inside the shell 01 to the greatest extent possible, thereby improving the mixing efficiency and promoting uniform mixing of the raw materials and asphalt.

[0030] The asphalt spraying device 02 is located inside the housing 01 and includes an asphalt delivery pipe 21 and a distribution pipe 22. The asphalt delivery pipe 21 is located below the second drive shaft 32 along the length of the housing 01. The distribution pipes 22 are arranged at equal intervals along the axis of the first drive shaft 31. One end of the distribution pipe 22 is connected to the asphalt delivery pipe 21 and is provided with a discharge port 23. One end of the asphalt delivery pipe 21 extends outside the housing 01 and can be connected to an external source of liquid asphalt. The liquid asphalt is pressurized by a booster pump and then delivered to the asphalt delivery pipe 21 through a pipeline. From the asphalt delivery pipe 21, it is delivered to the distribution pipe 22. Asphalt is injected from the inside of the raw material using the distribution pipe 22, and then the first transmission shaft 31 and the second transmission shaft 32 drive the stirring assembly 33 to stir and stir the raw material, so that the asphalt is mixed with the raw material from the inside to the outside, thereby achieving uniform mixing of the asphalt and the raw material in a short time, which not only shortens the mixing time and improves production efficiency, but also reduces energy consumption, achieving the company's preset quality improvement and efficiency improvement goals.

[0031] In one embodiment, the distribution pipe 22 is a U-shaped structure, the width of the distribution pipe 22 is greater than the width of the material turning assembly, and the height of the distribution pipe 22 is greater than the height of the material turning assembly.

[0032] Specifically, the feed pipes 22 are arranged in an interlaced manner with the stirring assemblies 33 mounted on the first transmission shaft 31. This allows the stirring assemblies 33 to interfere with the feed pipes 22 while also allowing the liquid asphalt ejected from the feed pipes 22 to approach the stirring assemblies 33. When the stirring assemblies 33 are driven by the first transmission shaft 31 to stir, the raw materials and the asphalt are brought into contact with each other to achieve mixing.

[0033] Please see Figure 7 In one embodiment, the stirring assembly 33 includes a disc fixing seat 331, a connecting rod 332, and a turning portion 333; the disc fixing seat 331 is axially evenly installed on the first transmission shaft 31 and the second transmission shaft 32, and the disc fixing seat 331 installed on the first transmission shaft 31 and the disc fixing seat 331 installed on the second transmission shaft 32 are staggered. The connecting rod 332 is installed along the radial direction of the disc fixing seat 331 and is circumferentially evenly distributed on the outer wall of the disc fixing seat 331. The turning portion 333 is installed at the end of the connecting rod 332.

[0034] Specifically, the bottom surface of the turning portion 333 where it connects to the connecting rod 332 is flat, and the two side surfaces of the turning portion 333 are inclined toward the middle to form a dividing slope 334, so that the cross section of the turning portion 333 is a triangular structure.

[0035] Specifically, the two ends of the turning part 333 are inclined toward one side of the connecting rod 332 and form a first cutting slope 335. The lower part of the first cutting slope 335 is inclined toward the middle of the bottom surface of the turning part 333 and forms a second cutting surface 336. When the turning part 333 rotates circumferentially, the first cutting slope 335 and the second cutting surface 336 of the turning part 333 are the first to contact the raw material and asphalt. Since the top end of the two ends of the turning part 333 is relatively small, the width and thickness gradually increase as the turning part goes further back. Under the impact of the turning part 333, the first cutting slope 335 and the second cutting surface 336 can be used to cut a gap in the raw material and asphalt, and the raw material and asphalt will spread outward. Then, due to the setting of the dividing slope 334, the middle part of the turning part 333 will be inclined toward the middle. , so that the middle part of the turning part 333 gradually narrows from bottom to top, thereby forming a knife-like structure. Under the rotation of the turning part 333, the raw materials and asphalt will be divided to both sides of the turning part 333. The dividing slope 334 is used to form a circumferential cutting effect on the raw materials and asphalt, which can not only form lateral stirring, but also drive the flow of raw materials and asphalt in the circumferential direction, greatly increasing the mixing efficiency; secondly, the bottom surface of the turning part 333 can turn the raw materials and asphalt upward, so that the raw materials and asphalt can be mixed evenly in a short time.

[0036] The disc holder 331 is provided with a weight-reducing hole 337. This not only reduces the overall weight of the disc holder 331, but also allows the weight-reducing hole 337 to drive the flow of raw materials and asphalt near the surfaces of the first and second transmission shafts 31, 32 as the disc holder 331 rotates. The raw materials and asphalt can both flow circumferentially due to the centrifugal force of the disc holder 331 and flow radially through the weight-reducing hole 337, thereby maximizing contact and mixing between the raw materials and asphalt near the surfaces of the first and second transmission shafts 31, 32.

[0037] In one embodiment, a feed port 11 is provided on the top of the housing 01 to facilitate the addition of raw materials.

[0038] In one embodiment, the bottom of the shell 01 is arc-shaped, so that the turning assembly on the second transmission shaft 32 can more easily turn the raw materials and asphalt at the bottom of the shell 01 upward.

[0039] In one embodiment, an interlayer may be added to the outer wall of the shell 01, and an electric heating belt or other heat source, such as steam, a water medium with heat, or an oil medium, may be installed in the interlayer to ensure the temperature inside the shell 01.

[0040] The above disclosure is only a preferred embodiment of the present invention, and it is certainly not intended to limit the scope of the rights of the present invention. A person skilled in the art can understand that all or part of the processes of the above embodiment and equivalent changes made in accordance with the claims of the present invention are still within the scope of the present invention.
