Description

Technical Field

[0001] This utility model relates to the field of carbon material purification technology, and in particular to a high-temperature gas circulation device for carbon material purification. Background Technology

[0002] Carbon material purification aims to remove impurities and obtain high-purity products. Mainstream methods include high-temperature heat treatment (removing volatile impurities at high temperatures in an inert atmosphere), acid-base chemical methods (using acid / alkali solutions to dissolve metal and oxide impurities), and gas-phase halogenation (using chlorine or similar gases to react with metal impurities to generate volatile chlorides for removal). These methods can be used individually or in combination to meet the extreme performance requirements of materials in fields such as electronics and aerospace.

[0003] The purification of carbon materials needs to be completed through a graphitization furnace. During the purification process, heat needs to be continuously increased to make the purification effect of carbon materials more obvious and stronger, and reduce the probability of soft carbon. The heat generated by the graphitization furnace needs to be kept at the same temperature. Currently, simple graphitization furnaces usually keep heating to maintain the current temperature, which not only increases energy consumption, but also increases processing costs.

[0004] To this end, we designed a high-temperature gas circulation device for the purification of carbon materials. Utility Model Content

[0005] The purpose of this invention is to solve the problem of high heating costs in existing technologies by proposing a high-temperature gas circulation device for purifying carbon materials.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0009] The detection component is installed on the heat transfer pipe and is used to detect the temperature of the gas passing through the heat transfer pipe (1).

[0010] Preferably, the heater is connected to the circulation pipe via a sleeve, the circulation pipe is provided with a heat insulation component, the sleeve is provided with a one-way valve, the rotating shaft is connected to the one-way valve, and the valve plate rotates on the rotating shaft.

[0011] Preferably, the central plate is connected to the gas supply pipe, the heating end is fixed to the output end of the central plate, the top of the heater is provided with an outlet pipe for discharging waste gas, and a heat sink is provided on one side of the heater, the heat sink being connected to the heater through a conduit.

[0014] Preferably, the heat insulation component includes a plurality of first heat insulation cottons disposed on the circulation pipe, an output pipe disposed at one end of the circulation pipe, and second and third heat insulation cottons disposed on the output pipe.

[0015] Preferably, the first insulation cotton is fixed to the outer wall of the circulation pipe, and the second and third insulation cotton are fixed to the outer wall of the output pipe.

[0016] The beneficial effects of this utility model are as follows:

[0017] 1. This utility model, through the setting of a thermometer and a heater, when the graphitization furnace injects the heat to be circulated into the heat transfer pipe, the thermometer will immediately measure the initial temperature. When the temperature in the batch of high-temperature gas is lower than expected, the heater will drive multiple heating ends to heat the circulation pipe, thereby achieving a rapid heating effect. At the same time, with the action of multiple first insulation cotton, the heat loss of the circulation pipe can be reduced, and the guarantee of continuous circulation of high-temperature gas can be improved, thereby reducing energy consumption and processing costs.

This not only prevents the high-temperature gas from leaking from the heater, but also improves the sealing of the top of the heating end and the turning efficiency during the start-up of the heating end, thereby increasing the heating efficiency of the high-temperature gas.

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0027] Reference Figures 1-6 A high-temperature gas circulation device for carbon material purification includes a heat transfer pipe 1, a circulation pipe 3 installed on the heat transfer pipe 1, and an output device 6 installed at the tail end of the circulation pipe 3. It also includes a heating component and a detection component. The heating component primarily heats the circulation pipe 3 and the high-temperature gas inside, reducing heat loss as the high-temperature gas passes through the circulation pipe 3. The detection component primarily detects the high-temperature gas upon its initial entry into the heat transfer pipe 1. If the high-temperature gas temperature falls below the expected temperature, the heating process of the heating component is triggered.

[0028] When connecting the high-temperature gas exhaust structure of the graphitization furnace, first connect the heat transfer pipe 1 and the circulation pipe 3 to each other. During the connection, ensure that the detection component has been installed. Then check the output device 6 at the end of the circulation pipe 3 to ensure that the output high-temperature gas will not leak. Then check that the heating component is ignited normally and that there is no gas leakage inside the heating component.

[0029] Reference Figures 4-6 The heating component includes a heater 4 disposed at the bottom of the circulation pipe 3, a central plate 401 disposed in the heater 4, several heating ends 402 disposed on the central plate 401, a gas supply pipe 403 disposed in the heater 4, a rotating shaft 406 disposed in the heater 4, and valve plates 407 symmetrically disposed on the rotating shaft 406.

[0030] The heater 4 is connected to the circulation pipe 3 through a sleeve. The circulation pipe 3 is equipped with a heat insulation component. The sleeve is equipped with a one-way valve. The rotating shaft 406 is connected to the one-way valve. The valve plate 407 rotates on the rotating shaft 406.

[0031] The central plate 401 is connected to the gas supply pipe 403, the heating end 402 is fixed to the output end of the central plate 401, the top of the heater 4 is provided with an exhaust pipe 408 for discharging waste gas, and a heat sink 405 is provided on one side of the heater 4. The heat sink 405 is connected to the heater 4 through a conduit 404.

[0032] When the high-temperature gas in the circulation pipe 3 needs to be heated, the heater 4 is first connected to an external power supply and controlled. Then, the heater 4 is started to ignite the top of the internal heating end 402. During ignition, a heated airflow is generated in the heater 4, which forces the top valve plate 407 to open on the rotating shaft 406, so that the high-temperature airflow rushes into the circulation pipe 3 and merges with the original high-temperature gas to increase the temperature. When the temperature reaches the expected temperature, the heater 4 can be turned off to cool the central plate 401 in the heater 4, reduce the overload of the heating end 402, and also reduce the pressure between the gas supply pipe 403 and the heating end 402. During the heating period, the high-temperature airflow will also rush into the duct 404 to heat the heat sink 405 and keep it in a heat-releasing state, so as to provide an external auxiliary heating effect for the top circulation pipe 3.

[0033] The sleeve at the top of the heater 4 is a commonly used connecting sleeve. It is made of metal and is connected to the beginning of the circulation pipe 3. The one-way valve on the sleeve is a common structure. By rotating it, the slack of the rotating shaft 406 can be changed, and the slack of the valve plate 407 rotating on the rotating shaft 406 can be adjusted. The rotating shaft 406 can also be completely locked by rotating it to deal with the situation where the flame at the heating end 402 is not extinguished.

[0034] The heating end 402 needs to be fixed to the central plate 401 by threaded connection for easy disassembly and assembly later. The central plate 401 is a common gas coil and has an ignition structure. One side of the central plate 401 needs to be fixedly connected to the gas pipeline 403 by welding to ensure connection strength and reduce gas leakage. The gas outlet pipe 408 at the top of the heater 4 is used to discharge the exhaust gas produced after combustion. It can be connected to the purification equipment through the auxiliary pipe to reduce the internal pressure of the heater 4.

[0035] Reference Figures 2-3The detection component is set on the heat transfer pipe 1. The detection component includes a thermometer 2 set on the heat transfer pipe 1, several thermometers 201 set inside the heat transfer pipe 1, a ring set around the thermometers 201, a transmission line 202 set on the ring, a support rod 203 set on the transmission line 202, and a collar 204 set on the heat transfer pipe 1.

[0036] The temperature measuring body 201 is pressed against the inner wall of the heat transfer pipe 1, the ring is fixed to the side wall of the temperature measuring body 201, the support rod 203 is fixed to the temperature measuring device 2, and the collar 204 is connected to the heater 4 through the branch pipe 205.

[0037] The insulation component includes several first insulation cotton 301s disposed on the circulation pipe 3, an output pipe 5 disposed at one end of the circulation pipe 3, and second insulation cotton 501 and third insulation cotton 502 disposed on the output pipe 5.

[0038] The first insulation cotton 301 is fixed to the outer wall of the circulation pipe 3, and the second insulation cotton 501 and the third insulation cotton 502 are fixed to the outer wall of the output pipe 5.

[0039] After the heat transfer pipe 1 is connected to the high-temperature gas exhaust equipment of the graphitization furnace, the temperature sensor 201 embedded in the inner wall of the heat transfer pipe 1 will detect the high-temperature gas. The detected data will be transmitted through the transmission line 202 through the support rod 203 to the temperature sensor 2, which will detect it in real time. When the temperature is lower than the preset temperature value, it will transmit information to the heater 4 through the branch pipe 205, so that the heater 4 can heat the high-temperature gas in the circulation pipe 3. The support rod 203 at the bottom of the temperature sensor 2 is fixed to the heat transfer pipe 1 by the collar 204, which is connected to the heat transfer pipe 1 by welding. The branch pipe 205 at the bottom is used to protect the wires connecting the temperature sensor 2 to the heater 4 and ensure data synchronization.

[0040] The first insulation cotton 301, uniformly installed on the circulation pipe 3, is used for auxiliary insulation to reduce the temperature loss of the circulation pipe 3. The first insulation cotton 301 can be tied to the circulation pipe 3 by a strap. The circulation pipe 3 and the output device 6 are connected by the output pipe 5. The diameter of the output pipe 5 is smaller than that of the circulation pipe 3. The pressure after the high temperature gas enters can increase the output speed. The second insulation cotton 501 and the third insulation cotton 502 on the output pipe 5 cover most of the area of ​​the output pipe 5 to reduce the temperature loss when input to the output device 6. Both are fixed to the output pipe 5 by a strap.

[0041] It should be noted that the thermometer 2 is a common temperature detection device. By setting a preset temperature value, it will be triggered immediately when the temperature of the high-temperature gas passing by is lower than the preset temperature value. The thermometer 201 is a detection device that the thermometer 2 penetrates into the heat transfer pipe 1. Multiple thermometers 201 need to be fixed together by a ring. The ring is a metal ring that fits against the inner wall of the heat transfer pipe 1.

[0042] The first insulation cotton 301, the second insulation cotton 501, and the third insulation cotton 502 are all common insulation materials used in construction, industrial equipment, and other fields. They are porous fibrous materials that provide insulation, heat insulation, sound absorption, and fire resistance. Their main principle is to trap a large amount of air, utilizing the property that air is a poor conductor of heat to prevent heat transfer.

[0043] The working principle of this utility model is as follows:

[0044] When the graphitization furnace requires high-temperature gas circulation, the heat transfer pipe 1 is connected to the high-temperature gas output device of the graphitization furnace. After the high-temperature gas enters the heat transfer pipe 1, it will be detected by multiple temperature sensors 201. When the temperature of the gas flowing through it is lower than the preset temperature value, the temperature sensor 2 will transmit the signal to the heater 4 below through the branch pipe 205. The multiple heating ends 402 inside the heater 4 will immediately ignite and heat. During this period, the slack of the shaft 406 on the one-way valve can be adjusted so that the heated high-temperature gas flow can quickly enter the circulation pipe 3. After heating, the high-temperature gas flow merges with the original high-temperature gas and fills the entire circulation pipe 3. The first insulation cotton 301 on the circulation pipe 3 can play an auxiliary role in heat preservation and reduce the heat loss of the circulation pipe 3. During this period, the output pipe 5 at the end of the circulation pipe 3 will also be insulated by the second insulation cotton 501 and the third insulation cotton 502 to reduce the heat loss of the high-temperature gas before it enters the output device 6. With the setup of thermometer 2 and heater 4, when the graphitization furnace injects the heat to be circulated into the heat transfer pipe 1, thermometer 2 will immediately measure the initial temperature. When the temperature in the batch of high-temperature gas is lower than expected, heater 4 will drive multiple heating ends 402 to heat the circulation pipe 3, thereby achieving a rapid heating effect. At the same time, under the action of multiple first insulation cotton 301, the heat loss of circulation pipe 3 can be reduced, improving the guarantee of continuous circulation of high-temperature gas, thereby reducing energy consumption and processing costs.

[0045] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
