Description

Technical Field

[0001] The utility model relates to the technical field of graphite electrode processing mechanisms, in particular to a graphite electrode baking temperature control mechanism. Background Art

[0002] Graphite electrodes are made of petroleum coke and needle coke as the main materials and are formed into conductor materials through mechanical processing. Graphite electrodes are light in weight, have good thermal stability, and are processed faster than copper materials. Graphite materials are a better raw material for making electrodes. During the production process, graphite electrodes are formed through calcination, batching, kneading, pressing, roasting, graphitization and other processing steps. Roasting requires the use of a roasting furnace for processing. During the graphite electrode roasting process, temperature is a very important parameter that directly affects the quality and performance of the electrode. Therefore, the roasting temperature needs to be precisely controlled.

[0003] During the roasting of the existing graphite electrodes, the internal temperature of the reactor cannot be monitored in real time to perform the next temperature control operation. Therefore, when the temperature is too high or too low, it is easy to cause the reaction to be interrupted or insufficient, thereby reducing the roasting rate of the graphite electrode. At the same time, when the graphite electrode is roasted, waste gas is easily generated. The existing reactor cannot effectively treat these waste gases in time, which is easy to affect the subsequent reaction. Utility Model Content

[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] Reference Figure 1-Figure 3 The utility model provides an embodiment: a graphite electrode baking temperature control mechanism, including a reaction furnace 1, a baking drawer 2 is slidably connected inside the reaction furnace 1, a handle 3 is fixedly connected to the outer wall of the baking drawer 2, a support plate 4 is fixedly connected inside the reaction furnace 1, a baffle 5 is fixedly connected to the outer wall of the support plate 4, an annular tube 6 is fixedly connected inside the reaction furnace 1, an ignition platform 7 is fixedly connected to the outer wall of the annular tube 6, a partition 8 is fixedly connected inside the reaction furnace 1, a stirring component is arranged on the top of the outer wall of the reaction furnace 1, and the stirring component is used to fully stir the hot air inside the reaction furnace 1. 1 is fixedly connected to the outer wall of a water tank 12, a cooling plate 13 is slidably connected to the inside of the water tank 12, a water outlet pipe 15 is fixedly connected to the inside of the water tank 12, a one-way valve 14 is fixedly connected to the outer wall of the water outlet pipe 15, one end of the water outlet pipe 15 is fixedly connected to a cooling pipe 17, one end of the cooling pipe 17 is fixedly connected to a water inlet pipe 16, and one end of the water inlet pipe 16 is fixedly connected to the inside of the water tank 12; the stirring assembly includes a motor 9, the outer wall of the motor 9 is fixedly connected to the top of the outer wall of the reaction furnace 1, the output end of the motor 9 is fixedly connected to a rotating shaft 10, and the outer wall of the rotating shaft 10 is fixedly connected to a stirring blade 11;

[0024] Specifically, when the roasting temperature needs to be precisely controlled, the temperature sensor 27 is used to detect the temperature inside the reaction furnace 1. If the temperature is low, the annular tube 6 delivers gas to the ignition table 7, and the ignition table 7 ignites and burns. However, the setting of the partition 8 can prevent the direct open flame from overheating the graphite electrode in the roasting drawer 2. The design of the baffle 5 helps to guide the rising hot air to ensure that the hot air flows fully inside the roasting drawer 2 to evenly heat and roast the graphite electrode. At the same time, the output end of the motor 9 drives the shaft 10 to drive the stirring blade 11 to rotate. The movement of the stirring blade 11 ensures that the hot air is fully mixed and Stirring improves the uniformity and efficiency of roasting. If the temperature inside the reactor 1 rises, the one-way valve 14 opens to allow the coolant in the water tank 12 to flow to the cooling pipe 17 through the outlet pipe 15. The cooling pipe 17 reduces the temperature at the bottom of the roasting drawer 2. Subsequently, the water inlet pipe 16 returns the coolant in the cooling pipe 17 to the water tank 12. The cooling plate 13 further reduces the temperature of the coolant, realizing a circulating cooling process of the coolant, thereby being able to accurately adjust the temperature inside the reactor 1. This not only improves the practicability and accuracy of the temperature control mechanism, but also accelerates the reaction rate of the graphite electrode, thereby improving the efficiency and reliability of the overall equipment.

[0025] Reference Figure 1 , Figure 2 and Figure 4 , a filter plate 18 is fixedly connected to the inside of the reaction furnace 1; an air pump 19 is fixedly connected to the top of the outer wall of the reaction furnace 1, and an air inlet pipe 20 is fixedly connected to the output end of the air pump 19; a reaction chamber 21 is fixedly connected to the outer wall of the air inlet pipe 20, and a chamber door 26 is rotatably connected to the inside of the reaction chamber 21; a placement box 22 is fixedly connected to the inside of the reaction chamber 21, and the outer wall of the air inlet pipe 20 is slidably connected to the inside of the placement box 22; an air outlet pipe 23 is fixedly connected to the inside of the reaction chamber 21, and a shunt pipe 24 is fixedly connected to the outer wall of the air outlet pipe 23; a nozzle 25 is fixedly connected to the inside of the shunt pipe 24, and a temperature sensor 27 is fixedly connected to the inside of the reaction furnace 1;

[0026] Specifically, when it is necessary to collect and process the waste gas, the waste gas is initially filtered through the filter plate 18 to remove most of the solid particles or other impurities. The filtered gas is introduced into the reaction chamber 21 through the vacuum pump 19 and the air inlet pipe 20. In the reaction chamber 21, the gas reacts with the sodium hydroxide in the placement box 22. The oxygen generated by the reaction continues to flow into the diversion pipe 24 through the outlet pipe 23. The nozzle 25 connected to the diversion pipe 24 sprays the oxygen onto the ignition table 7, which helps to speed up the combustion rate in the ignition table 7 because the addition of oxygen promotes the combustion reaction, thereby effectively treating the waste gas generated during the reaction. This not only helps to reduce the impact on the environment, but also optimizes the energy utilization efficiency during the reaction.

[0027] Working principle: When the roasting temperature needs to be regulated, the temperature inside the reactor 1 is monitored by the temperature sensor 27. When the temperature inside the reactor 1 is low, gas is supplied to the ignition platform 7 through the annular pipe 6, so that the ignition platform 7 can be opened for combustion. At the same time, the partition 8 can prevent the open flame provided by the ignition platform 7 from directly heating the roasting drawer 2, and the baffle 5 can guide the rising hot air so that the hot air can fully flow upward to fully roast the graphite electrodes inside each layer of the roasting drawer 2. At the same time, the output end of the motor 9 drives the rotating shaft 10 to drive the stirring blade 11 to rotate, so that the stirring blade 11 can fully stir and mix the hot air, thereby evenly roasting the graphite electrodes. When the temperature inside the reactor 1 is high, by opening the one-way valve 14, the coolant inside the water tank 12 can flow from the outlet pipe 15 to the cooling pipe 17, thereby making the cooling pipe 1 7 can cool down the bottom of the roasting drawer 2, and then the water inlet pipe 16 can return the coolant that has been warmed up inside the cooling pipe 17 to the inside of the water storage tank 12, and then the cooling plate 13 is used to cool down the temperature, so as to realize the circulation cooling of the coolant, thereby achieving the effect of regulating the reaction temperature, improving the practicality of the temperature control mechanism, and accelerating the reaction rate of the graphite electrode. When it is necessary to collect the exhaust gas, the exhaust gas can be preliminarily filtered by the filter plate 18, and the filtered gas can be sucked into the reaction chamber 21 by the vacuum pump 19 and the air inlet pipe 20, so that the exhaust gas can react with the sodium hydroxide contained in the placement box 22, and the generated oxygen can continue to pass into the shunt pipe 24 through the exhaust pipe 23, and then be sprayed toward the ignition table 7 by the nozzle 25, thereby accelerating the combustion rate of the ignition table 7, thereby achieving the effect of absorbing the exhaust gas generated by the reaction, and improving the efficiency of the temperature control mechanism.
