Description

Technical Field

[0001] This invention relates to the field of mixing pot technology, and more specifically to a negative pressure dust-collecting graphite electrode raw material mixing pot. Background Technology

[0002] The kneading pot is a high-efficiency device specifically designed for mixing semi-dry materials. Its core components are a pair of Z-shaped parts. The mixing pot, with its shaped stirring blades and hydraulic system controlling the tilting, opening, and discharging of the cylinder, is the core equipment for producing high-quality graphite electrodes. Its performance directly affects the mechanical strength, conductivity, and thermal shock resistance of the electrodes. Graphite electrode raw materials use calcined petroleum coke or needle coke as aggregate and coal tar pitch as binder. Through reasonable gradation, a uniform plastic paste is formed for the production of graphite electrodes. During the mixing process of graphite electrode raw materials, a large amount of dust and asphalt fumes are generated, requiring a negative pressure dust collection system to absorb these fumes. However, when existing mixing pots are subjected to negative pressure dust collection, the fumes condense inside the upper structure such as the pot lid and vacuum pipes, forming asphalt tar. These coke deposits are very easy to fall into the paste, forming hard impurities that seriously affect the final quality of the electrodes. In addition, after the electrode paste is discharged from the mixing pot, the residual paste adhering to the blades and the pot wall is very difficult to clean, which is time-consuming and labor-intensive. Therefore, we provide a negative pressure dust collection graphite electrode raw material mixing pot to solve the above problems. Summary of the Invention

[0003] In order to overcome the above-mentioned defects of the prior art, the present invention provides a negative pressure dust collection graphite electrode raw material mixing pot to solve the problems existing in the background art.

[0004] To achieve the above objectives, the present invention provides the following technical solution: a negative pressure dust collection graphite electrode raw material mixing pot, comprising a driving assembly, the driving assembly comprising a base, a mixing pot assembly fixedly connected to the top of the base, two cleaning assemblies rotatably connected to the inner side of the mixing pot assembly, a pot lid shell fixedly connected to the top of the mixing pot assembly, a connecting pipe sleeved on the top of the pot lid shell, an oil-collecting assembly installed at the bottom of the connecting pipe, and a fan wheel fixedly connected to the bottom of the oil-collecting assembly; The cleaning component cleans the paste from the side wall of the mixing pot component, and the connecting pipe works with the oil-polymerizing component to polymerize and liquefy the flue gas and recycle and reuse it in real time. An arc plate is fixedly connected to the side of the wind turbine. The arc plate is inclined at 45°. The arc plate works with the mixing pot assembly to facilitate the cleaning of the paste.

[0005] Furthermore, a kneading component is fixedly connected to one end of the top of the driving component, and a pot lid component is fixedly connected to the top of the kneading component.

[0006] Furthermore, a motor is fixedly connected to one side of the top of the base, a transmission mechanism is fixedly connected to the drive end of the motor, a transmission mechanism is rotatably connected to one side of the transmission mechanism, a transmission mechanism is rotatably connected to one side of the transmission mechanism, and two rotating shafts are rotatably connected to one side of the transmission mechanism. One end of the two rotating shafts is rotatably sleeved with a kneading pot assembly, and is rotatably sleeved on one side of the kneading pot assembly.

[0007] Furthermore, a second motor is fixedly connected to the rear side of the top center of the base. The drive end of the second motor is rotatably connected to a transmission component. A connecting shaft is rotatably connected to one side of the transmission component. One end of the connecting shaft is rotatably sleeved on the bottom end of one side of the mixing pot assembly and is on the same side as the rotating shaft.

[0008] Furthermore, the kneading assembly includes a kneading pot assembly, the bottom of which is fixedly connected to the top of the base. Two cleaning assemblies are rotatably connected to the inner sides of both sides of the kneading pot assembly, and one end of each cleaning assembly is fixedly connected to one end of two rotating shafts.

[0009] Furthermore, the mixing pot assembly includes a pot body, with two guide plates fixedly connected to the inner side of the bottom end of the pot body. The two guide plates are respectively fixedly connected to the inner sides of the front and back of the pot body, forming a discharge groove between the two guide plates. A threaded rod is rotatably sleeved on the inner side of the bottom end of the pot body, and the threaded rod is located below the discharge groove. The threaded rod is fixedly connected to one end of a connecting shaft, and a discharge pipe is fixedly connected to the bottom end of one side of the pot body.

[0010] Furthermore, the cleaning assembly includes a stirring paddle, both ends of which are fixedly connected to round shafts. One end of each of the two round shafts is fixedly connected to an outer shaft. The two outer shafts are rotatably sleeved on one side of the pot body. A transmission disc is fixedly sleeved on the side of each of the two round shafts. The transmission disc includes an annular shell. An annular gear is provided on the inner side of the annular shell, with the teeth facing inward. Three sub-gears mesh on the inner side of the annular gear. A central gear meshes on the side of the three sub-gears. The round shaft is fixedly sleeved on the inner side of the central gear.

[0011] Furthermore, scrapers are fixedly connected to the top and bottom of both ring shells, and scraper blades are fixedly connected to the top of the scrapers at the top and bottom.

[0012] Furthermore, the pot lid assembly includes a pot lid shell, the top of which is fixedly connected to a connecting pipe, a fan wheel is rotatably sleeved on the inner side of the connecting pipe, a connecting roller is fixedly connected to the bottom of the fan wheel, an oil-collecting component is fixedly connected to the bottom of the connecting roller, and the oil-collecting component is rotatably sleeved on the bottom of the pot lid shell, a fan wheel is fixedly connected to the bottom of the oil-collecting component, and several arc plates are fixedly connected to the side of the fan wheel.

[0013] Furthermore, the oil-collecting component includes a turntable, the bottom edge of which is provided with an annular groove, and the bottom of the turntable is provided with six guide grooves, which divide the bottom of the turntable into six fan-shaped blocks. One side of each of the six fan-shaped blocks is provided with a side groove, and the top of each of the six fan-shaped blocks is provided with several venting grooves, which are connected to the pot lid shell.

[0014] The technical effects and advantages of this invention are as follows: 1. A negative pressure dust collection system is connected via a connecting pipe. The negative pressure of the system drives the fan wheel to rotate, which in turn causes the oil collection component to rotate. When the rising oil-gas mixture approaches the lid shell, it is sucked into the side groove by the negative pressure in the vent holes. As the turntable rotates continuously, the oil and gas continuously adhere to the inner wall of the side groove and accumulate into liquid droplets. The liquid droplets are thrown along the side groove towards the annular groove of the turntable by the centrifugal force of the turntable's rotation, instead of condensing at the bottom of the turntable. Due to gravity and centrifugal force, the liquid droplets fall back into the paste being mixed below. This solves the problem that when flue gas condenses inside the upper structure such as the lid and vacuum pipe, it forms asphalt tar. These coking deposits are very easy to fall into the paste, forming hard impurities that seriously affect the final quality of the electrode.

[0015] 2. The motor drives the stirring paddle to mix and knead the graphite electrode raw material. The transmission disc drives the scraper to rotate and clean the paste on the side wall of the pot and the scraper blade to rotate and clean the paste at the bottom of the pot. After the paste is discharged, the paste adhering to the inner wall of the pot is cleaned into the discharge chute and discharged. This avoids the problem of the difficulty in cleaning the residual paste adhering to the paddle blade and the pot wall after the electrode paste is kneaded and discharged. In addition, the scraper blade also rotates during the kneading process. The scraper blade located above the paste blows the dust and flue gas generated during the kneading of the graphite electrode raw material toward the pot lid assembly, which promotes the liquefaction and accumulation of flue gas and improves the negative pressure dust collection effect.

[0018] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings.

[0020] In this embodiment, it is necessary to further explain that the kneading component 2 avoids the problem that it is very difficult to clean the residual paste adhering to the paddle and the pot wall after the electrode paste is kneaded and discharged. The pot lid component 3 solves the problem that the flue gas condenses inside the upper structure such as the pot lid and vacuum pipe, forming asphalt tar. These coking substances are very easy to fall off and fall into the paste, forming hard impurities, which seriously affect the final quality of the electrode. The specific structure and working principle of the above components will be explained in detail later.

One end of the two rotating shafts 103 is rotatably sleeved on a mixing pot assembly 201 and rotatably sleeved on one side of the mixing pot assembly 201. A second motor 104 is fixedly connected to the rear side of the top middle of the base 101. The drive end of the second motor 104 is rotatably connected to a transmission assembly 105. A connecting shaft 106 is rotatably connected to one side of the transmission assembly 105. One end of the connecting shaft 106 is rotatably sleeved on the bottom end of one side of the mixing pot assembly 201 and is on the same side as the rotating shaft 103.

[0022] In this embodiment, it should be specifically noted that transmission mechanism one, transmission mechanism two, and transmission mechanism three are all conventional technical means in the prior art, and therefore will not be described in detail.

[0023] Reference Figure 4 and Figure 5 The kneading component 2 includes a kneading pot component 201. The bottom of the kneading pot component 201 is fixedly connected to the top of the base 101. Two cleaning components 202 are rotatably connected to the inner sides of both sides of the kneading pot component 201, and one end of each of the two cleaning components 202 is fixedly connected to one end of each of the two rotating shafts 103.

[0024] Reference Figure 6 and Figure 7 The mixing pot assembly 201 includes a pot body 2011. Two guide plates 2012 are fixedly connected to the inner side of the bottom end of the pot body 2011. The two guide plates 2012 are fixedly connected to the inner sides of the front and back of the pot body 2011, respectively. A discharge groove is formed between the two guide plates 2012. A threaded rod 2013 is rotatably sleeved on the inner side of the bottom end of the pot body 2011. The threaded rod 2013 is located below the discharge groove. The threaded rod 2013 is fixedly connected to one end of the connecting shaft 106. A discharge pipe 2014 is fixedly connected to the bottom end of one side of the pot body 2011.

[0025] Reference Figure 8 and Figure 9The cleaning assembly 202 includes a stirring paddle 2021. Both ends of the stirring paddle 2021 are fixedly connected to round shafts. One end of each of the two round shafts is fixedly connected to an outer shaft. The two outer shafts are rotatably sleeved on one side of the pot body 2011. A transmission disc 2022 is fixedly sleeved on the side of each of the two round shafts. The transmission disc 2022 includes an annular shell. An annular gear is provided on the inner side of the annular shell, with the teeth facing inward. Three sub-gears mesh on the inner side of the annular gear. A central gear meshes on the side of the three sub-gears. The round shaft is fixedly sleeved on the inner side of the central gear. Scraper 2023 is fixedly connected to the top and bottom of both ring shells, and scraper blade 2024 is fixedly connected to the top of the scraper 2023 at the top and bottom.

[0026] The motor 102 drives the stirring paddle 2021 to stir and knead the graphite electrode raw material. The transmission disc 2022 drives the scraper 2023 to rotate and clean the paste on the side wall of the pot body 2011, and drives the scraper blade 2024 to rotate and clean the paste at the bottom of the pot body 2011. After the paste is discharged, the paste adhering to the inner wall of the pot body 2011 is cleaned into the discharge chute and discharged. This avoids the problem that it is very difficult to clean the residual paste adhering to the paddle blade and the pot wall after the electrode paste is kneaded and discharged. In addition, the scraper blade 2024 also rotates during the kneading process. The scraper blade 2024, which is located above the paste, blows the dust and flue gas generated during the kneading of the graphite electrode raw material towards the pot lid assembly, promoting the liquefaction and accumulation of flue gas and improving the negative pressure dust collection effect.

[0027] Reference Figure 10 The pot lid assembly 3 includes a pot lid shell 301. A connecting pipe 302 is fixedly connected to the top of the pot lid shell 301. A fan wheel is rotatably sleeved on the inner side of the connecting pipe 302. A connecting roller is fixedly connected to the bottom of the fan wheel. An oil-collecting assembly 303 is fixedly connected to the bottom of the connecting roller. The oil-collecting assembly 303 is rotatably sleeved on the bottom of the pot lid shell 301. A fan wheel 304 is fixedly connected to the bottom of the oil-collecting assembly 303. Several arc plates are fixedly connected to the side of the fan wheel 304, and the arc plates are inclined at 45°. In this embodiment, it is necessary to specifically explain that the top of the connecting pipe 302 is connected to a negative pressure dust collection system. The impeller 304 rotates with the oil-collecting component 303, which in turn causes the arc plate to rotate and generate airflow. Under the guidance of the side wall of the mixing pot component 201, the airflow is directed downwards, blowing off the paste on the side wall, which is beneficial for cleaning the paste on the side wall.

[0028] Reference Figure 11The oil-collecting component 303 includes a turntable 3031. The bottom edge of the turntable 3031 is provided with an annular groove, and the bottom of the turntable 3031 is provided with six guide grooves. The six guide grooves divide the bottom of the turntable 3031 into six fan-shaped blocks. One side of each of the six fan-shaped blocks is provided with a side groove, and the top of each of the six fan-shaped blocks is provided with several ventilation grooves. The ventilation grooves are connected to the pot lid shell 301. The negative pressure dust collection system is connected via connecting pipe 302. The negative pressure of the dust collection system drives the fan wheel to rotate, which in turn causes the oil collection component 303 to rotate. When the rising oil-gas mixture approaches the lid shell, it is sucked into the side groove by the negative pressure in the vent hole. As the turntable 3031 rotates continuously, the oil and gas continuously adhere to the inner wall of the side groove and accumulate into liquid droplets. The liquid droplets are thrown along the side groove towards the annular groove of the turntable 3031 by the centrifugal force of the rotation of the turntable 3031, instead of condensing at the bottom of the turntable 3031. Due to gravity and centrifugal force, the liquid droplets fall back into the paste body being mixed below, which is recycled and reused in real time. This solves the problem that the condensation of flue gas inside the upper structure such as the lid and vacuum pipe will form asphalt tar. These coking materials are very easy to fall off and fall into the paste, forming hard impurities, which seriously affect the final quality of the electrode.

[0029] The working principle of this invention is as follows: The motor 102 drives the stirring paddle 2021 to rotate and stir and knead the graphite electrode raw material. The transmission disc 2022 drives the scraper 2023 to rotate and clean the paste on the side wall of the pot body 2011, and drives the scraper blade 2024 to rotate and clean the paste at the bottom of the pot body 2011. After the paste is discharged, the paste adhering to the inner wall of the pot body 2011 is cleaned into the discharge trough and discharged. This avoids the problem that it is very difficult to clean the residual paste adhering to the paddle blade and the pot wall after the electrode paste is kneaded and discharged. In addition, the scraper blade 2024 also rotates during the kneading process. The scraper blade 2024 located above the paste blows the dust and flue gas generated during the kneading of the graphite electrode raw material toward the pot lid assembly, which promotes the liquefaction and accumulation of flue gas and improves the negative pressure dust collection effect. The negative pressure dust collection system is connected via connecting pipe 302. The negative pressure of the dust collection system drives the fan wheel to rotate, which in turn causes the oil collection component 303 to rotate. When the rising oil-gas mixture approaches the lid shell, it is sucked into the side groove by the negative pressure in the vent hole. As the turntable 3031 rotates continuously, the oil and gas continuously adhere to the inner wall of the side groove and accumulate into liquid droplets. The liquid droplets are thrown along the side groove towards the annular groove of the turntable 3031 by the centrifugal force of the rotation of the turntable 3031, instead of condensing at the bottom of the turntable 3031. Due to gravity and centrifugal force, the liquid droplets fall back into the paste body being mixed below. This solves the problem that the condensation of flue gas inside the upper structure such as the lid and vacuum pipe will form asphalt tar. These coking materials are very easy to fall off and fall into the paste, forming hard impurities that seriously affect the final quality of the electrode.
