According to the embodiment of the invention, a reminding device for broken carbon fibers is provided. Referring to fig. 1, a schematic diagram of an embodiment of the apparatus of the present invention is shown. The carbon fiber can be produced by a carbon fiber production system.

The reminding unit is configured to send out reminding messages under the condition that the reminding messages are triggered by the control unit so as to remind post personnel that the carbon fibers are broken in the blast furnace and/or the graphite furnace, so that production abnormity occurs and abnormity needs to be timely processed. The reminding message can be an alarm message sent by a buzzer and the like, and can also be a voice reminding message sent by a voice broadcaster.
Therefore, the alarm device is formed by the control unit and the reminding unit, the alarm is given when the carbon fiber is broken in the blast furnace and/or the graphite furnace in the carbon fiber production process, and the alarm for the broken carbon fiber can be sent in the following procedures (such as electrolysis, water washing and the like) when the carbon fiber is broken in the blast furnace and/or the graphite furnace in the carbon fiber production process. The post personnel can find and handle the production abnormity in time by immediately alarming when the carbon fiber is broken in the blast furnace and/or the graphite furnace in the carbon fiber production process.

Due to the adoption of the power-off delay relay, even if the broken tail of the carbon fiber leaves two copper wires, the alarm can be continued according to the preset time.
Through a large number of tests, the technical scheme of the invention is adopted, the alarm device formed by the control unit and the alarm unit is arranged by utilizing the conductivity of the carbon fiber, the alarm device is arranged outside the outlet of the blast furnace and/or the graphite furnace, when the carbon fiber is broken in the blast furnace and/or the graphite furnace, the broken fiber tail of the carbon fiber is output from the outlet of the blast furnace and/or the graphite furnace and then is connected with the alarm device in a lap joint manner, so that the alarm device is triggered to remind post personnel that the carbon fiber is broken in the blast furnace and/or the graphite furnace; therefore, the carbon fiber production reminding device can remind people at a high carbon furnace and/or a graphite furnace of breakage of the carbon fibers in the production process of the carbon fibers in time so as to remind the post personnel of handling in time, and is favorable for improving the yield and quality of carbon fiber production.

The production system of carbon fiber may include: the reminding device for the broken carbon fiber is characterized by comprising a reminding device.
It is considered that the carbon fiber has good conductivity after passing through a blast furnace and/or a graphite furnace. For example: in the production process of the carbon fiber, the pre-oxidized fiber passes through the low carbon furnace, and the carbon content is gradually increased through the reaction of the high carbon furnace, so that the carbon fiber has conductivity. Therefore, in the scheme of the invention, based on the conductivity of the carbon fiber after passing through the blast furnace and/or the graphite furnace, the scheme of the invention provides a device for giving an alarm when the carbon fiber breaks in the blast furnace and/or the graphite furnace, in particular to a device for giving an alarm when the carbon fiber breaks in the blast furnace and/or the graphite furnace in the production process of the carbon fiber, and the alarm can give an alarm for reacting the breakage of the carbon fiber in the following processes (such as electrolysis, water washing and the like) when the carbon fiber breaks in the blast furnace and/or the graphite furnace in the production process of the carbon fiber. The post personnel can find and handle the production abnormity in time by immediately alarming when the carbon fiber is broken in the blast furnace and/or the graphite furnace in the carbon fiber production process.
The following describes an exemplary implementation of the scheme of the present invention with reference to the example shown in fig. 2.
Fig. 2 is a schematic structural diagram of an embodiment of the device for generating an alarm when the carbon fiber breaks in the blast furnace and/or the graphite furnace according to the invention. As shown in fig. 2, the device for generating an alarm when the carbon fiber is broken in the blast furnace and/or the graphite furnace comprises: the power supply comprises a first power supply module (such as a first 12V power supply), a second power supply module (such as a second 12V power supply), a relay, two copper wires, an alarm and an alarm power supply. A relay, comprising: the alarm device comprises a starting module and a stopping module, wherein the relay can trigger a trigger signal of the alarm device when the starting module is switched on, and the relay can stop working when the stopping module works, so that the trigger signal of the alarm device is switched off.
Here, two power supply modules (e.g., a first power supply module and a second power supply module) are provided, so that two circuits corresponding to the start module and the stop module of the relay do not interfere with each other, and if the operating voltage of the relay and the trigger voltage of the relay are not the same, two power supplies are required. Of course, in practical use, the ranges of the specific power supply voltages of the first power supply module and the second power supply module can be flexibly set according to practical requirements, such as: here, the first power supply module and the second power supply module both use 12V power supplies, and since the first power supply module and the second power supply module both use 12V power supplies, one 12V power supply can be selected to be used in common.
In the example shown in fig. 2, the positive pole of the first power supply module is connected to a first end of a first one 21 of the two copper wires by a first conductor 11. The second end of the first copper wire 21 is suspended. The first end of the second copper wire 22 of the two copper wires is connected to the positive terminal of the power supply end of the starting module in the relay through the second wire 12. The first copper wire 21 and the second copper wire 22 are arranged in parallel, and the first end of the first copper wire 21 and the first end of the second copper wire 22 are correspondingly arranged ends of the two parallel copper wires and are close to the first power supply module. For example: the first end of the first copper wire 21 is the left end of the first copper wire 21, and the first end of the second copper wire 22 is the left end of the second copper wire 21. And the negative electrode of the first power supply module is connected to the power supply terminal negative terminal of the starting module in the relay through a third lead 13. Through the broken tail of two copper wires, first power module, relay and carbon fiber, can constitute relay trigger circuit.
Wherein, the copper wire of selecting for use must not have the insulated paint, in case touch the carbon fiber just can electrically conduct. When the trigger signal of the alarm is switched on, the alarm gives an alarm; and after the trigger signal of the alarm is disconnected, the alarm stops working after working for a preset time, and the process is repeated if the trigger signal exists.
In the example shown in fig. 2, the positive pole of the second power supply module is connected to the positive terminal of the power supply terminal of the stop module in the relay by a fourth wire 14. The negative pole of the second voltage module is connected to the negative terminal of the power supply terminal of the stop module in the relay by a fifth wire 15.
In the example shown in fig. 2, the output port of the relay is connected to the positive pole of the alarm by a sixth wire 16, and the input port of the relay is connected to the positive pole of the alarm power supply by a seventh wire 17. And the negative pole of the alarm power supply is connected to the negative pole of the alarm through an eighth lead wire 18.
The relay controls the on-off of the power supply of the alarm to control the alarm. For example: the relay triggers the action, so that the input port of the relay is connected with the output port of the relay, and the power supply of the alarm is connected to give an alarm. Another example is: and stopping alarming is carried out by stopping the working power supply of the relay, for example, the second power supply module is controlled to stop supplying power by the stop alarm switch, so that the working power supply of the relay stops supplying power, the input port of the relay is disconnected with the output port of the relay, and the alarm stops alarming. In addition, the alarm time of the alarm can be set in advance.
In some embodiments, in the device for generating the alarm when the carbon fiber is broken in the blast furnace and/or the graphite furnace, two copper wires are arranged right below a wire bundle at the outlet of the blast furnace, so that the tail of the carbon fiber can be simultaneously lapped on the two copper wires after the carbon fiber is broken, and due to the conductivity of the carbon fiber after passing through the blast furnace and/or the graphite furnace, when the tail of the broken carbon fiber is lapped on the two copper wires, a relay trigger circuit in the device for generating the alarm when the carbon fiber is broken in the blast furnace and/or the graphite furnace is switched on, and the alarm is triggered to alarm so as to remind a post person that the carbon fiber is broken in the blast furnace and/or the graphite furnace. Wherein, in the relay trigger circuit, the relay chooses the outage time delay relay for use.
In some preferred embodiments, considering that the position of the tow during operation is fixed and the copper wire is within 1cm directly below the running tow, false alarms are prone to being made, preferably 1cm-2cm (i.e. the copper wire is 1-2cm directly below the normal running tow), and more than 2cm, the further the copper wire is from the running tow, the longer the time it takes for the broken tail to simultaneously lie down on the copper wire, and the later the alarm. Two copper wires are arranged at a position 1-2cm right below the outlet tows of the high carbon furnace and/or the graphite furnace and are perpendicular to the running direction of the tows (namely the normal output direction of the tows, see arrows at the positions of the tows 31, 32, 33, 34 and 35 in the figure 2), and the distance between the two copper wires is only required to ensure that the fiber breaking tail can be simultaneously laid. When the carbon fiber is used as a device for generating an alarm when a wire break occurs in a high carbon furnace and/or a graphite furnace, when the wire break occurs in the furnace, the broken tail of the carbon fiber can loosen and droop on two copper wires. And when the broken fiber tail of the carbon fiber is simultaneously and dropwisely pulled on the two copper wires, the relay trigger circuit is switched on. The relay is a power-off delay relay, when the trigger signal is switched on, the alarm gives an alarm, when the trigger signal is switched off, the alarm stops working after working for preset time, and if the trigger signal is generated, the process is repeated.
Although the falling speed of the lighter fiber wires is slower, the falling time is longer, and the time from the output to the lap joint of the lighter fiber wires to the two copper wires is longer; the falling speed of the heavier fiber filaments or fiber bundles is higher, the falling time is shorter, and the time from the output to the lap joint of the two copper wires is shorter. However, as long as the copper wire is 1-2cm under the tows, the copper wire can be immediately touched no matter the tows are light and heavy as long as the broken wires occur, the broken wires are not limited by the running speed of the tows, if the installation distance of the copper wire from the tows exceeds 2cm, the weight of the tows is related, and the heavier the tows are, the earlier the copper wire is touched.
When the carbon fiber alarm device is used, the carbon fiber alarm device is used for generating an alarm when a wire break occurs in a high-carbon furnace and/or a graphite furnace, and two copper wires (such as a first copper wire 21 and a second copper wire 22) are arranged outside an outlet 4 of the high-carbon furnace and/or the graphite furnace and are positioned at a position 1-2cm below a wire bundle between the outlet 4 of the high-carbon furnace or the graphite furnace and a transmission roller. The arrangement direction of the two copper wires is vertical to the output direction of the tows output from the outlet 4 of the high carbon furnace or the graphite furnace.
In some preferred embodiments, there may be poor contact due to the lapping of the filaments or bundles of too fine carbon fibers over the copper wire. Therefore, the diameter of the copper wire is verified to be preferably 1.8-2.2mm, so that the broken tail output from the outlet 4 of the high carbon furnace or the graphite furnace can be lapped on the copper wire to be connected with the circuit of the copper wire. Preferably, the diameter of the copper wire is 2mm, so that the circuit where the copper wire is located can be reliably connected when the broken wire tail output from the outlet 4 of the high-carbon furnace or the graphite furnace is lapped on the copper wire.
In some preferred embodiments, the distance between the two copper wires (for example, the first copper wire 21 and the second copper wire 22) is between 28 and 32cm, so as to ensure that the broken tail output from the outlet 4 of the blast furnace and/or the graphite furnace can overlap the two copper wires. Preferably, it is verified that the distance between the two copper wires (for example, the first copper wire 21 and the second copper wire 22) is 30cm, so that the broken tail output from the outlet 4 of the blast furnace and/or the graphite furnace can be reliably lapped on the two copper wires, and therefore, the timely alarm can be ensured when the filament bundle output from the outlet 4 of the blast furnace and/or the graphite furnace is broken.
In addition, the device for alarming the carbon fiber when the carbon fiber is broken in a high carbon furnace and/or a graphite furnace is in a normal temperature environment. Therefore, the relay in the device for generating the alarm when the carbon fiber is broken in the blast furnace and/or the graphite furnace does not work in a high-temperature environment.
In conclusion, the scheme of the invention reasonably utilizes the conductivity of the carbon fiber and also reasonably utilizes the power-off delay relay. Through the function of reasonably utilizing good conductivity and relay time-delay power-off after the carbon fiber passes through high carbon, when the carbon fiber is broken, the broken tail of the carbon fiber only needs to droop on two copper wires at the same time, and the alarm gives an alarm immediately. Due to the adoption of the power-off delay relay, even if the broken fiber tail of the carbon fiber leaves two copper wires, the alarm can be continuously given according to the preset time.
Since the processing and functions of the carbon fiber production system of the present embodiment are basically corresponding to the embodiments, principles and examples of the foregoing apparatus, reference may be made to the related descriptions in the foregoing embodiments without being repeated in detail in the description of the present embodiment.
Through a large number of tests, the technical scheme of the invention is adopted, the alarm device formed by the control unit and the alarm unit is arranged by utilizing the conductivity of the carbon fiber, the alarm device is arranged outside the outlet of the blast furnace and/or the graphite furnace, when the carbon fiber is broken in the blast furnace and/or the graphite furnace, the broken fiber tail of the carbon fiber is output from the outlet of the blast furnace and/or the graphite furnace and then is connected with the alarm device in a lap joint manner, so that the alarm device is triggered to remind a post person that the carbon fiber is broken in the blast furnace and/or the graphite furnace, the broken fiber condition of the carbon fiber can be timely known and timely processed, the post person can timely find and process abnormal production, the reliable operation of the carbon fiber production process is favorably ensured, and the vitamin production quality and the yield of the carbon fiber are favorably ensured.
