Description

Technical Field

[0001] This utility model relates to the field of acetylene preparation technology, and in particular to a calcium carbide feeding system. Background Technology

[0002] The preparation of acetylene black requires a large amount of acetylene gas, and the raw material for acetylene gas is calcium carbide. The preparation of acetylene gas requires the calcium carbide to be placed in an acetylene generator for reaction. Existing calcium carbide feeding systems mainly consist of a calcium carbide hopper, an electric forklift, a monorail hoisting device, a receiving device, and a calcium carbide feed valve. The production process is as follows: The calcium carbide raw material is first processed by a crushing device, and the crushed lumps are then loaded into the calcium carbide hopper. After loading, an electric forklift transports the hopper to the hoisting well below the acetylene generator area and positions it at the hoisting position of the monorail hoisting device. The monorail hoisting device lifts the calcium carbide hopper above the inlet of the upper feeding hopper, and the discharge valve at the bottom of the hopper is manually opened, allowing the calcium carbide to sequentially enter the upper feeding hopper through the first calcium carbide feed valve, and then be conveyed to the lower feeding hopper through the second calcium carbide feed valve. Finally, the calcium carbide in the lower feeding hopper is quantitatively fed into the acetylene generator through a vibrating feeder to participate in the reaction.

[0003] However, the existing technical solutions mentioned above have the following drawbacks: First, the entire feeding process relies heavily on manual intervention, affecting production efficiency and making it difficult to meet the actual needs of large-scale continuous production; second, the system lacks an effective impurity removal process before the material reaction, which may result in the calcium carbide raw material entering the generator containing magnetic foreign objects, affecting product quality. Therefore, a highly automated calcium carbide feeding system is urgently needed to solve the above problems. Utility Model Content

[0021] The specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for illustration and explanation only and are not intended to limit the scope of this utility model.

[0022] This embodiment provides a calcium carbide feeding system, such as Figure 1 As shown, it includes a transfer device 1, a material distribution device 2, and multiple material collection and reaction devices 3; The unloading end of the transfer device 1 is connected to the feeding end of the distribution device 2. The transfer device 1 is used to transfer materials to the distribution device 2. The material distribution device 2 is provided with a material distribution chamber 221, which has an air inlet, a foreign matter outlet 222 and multiple discharge outlets 223. The material distribution chamber 221 is provided with a magnetic suction component 21 that adsorbs magnetic foreign matter in the material when the power is on and cancels the adsorption of magnetic foreign matter when the power is off. Each feed end of the aggregate reaction device 3 is connected to each discharge port 223 in a one-to-one correspondence.

[0023] In the calcium carbide feeding system provided in the above embodiment, the crushed material enters the distribution chamber 221 of the distribution device 2 through the transfer device 1, and then enters the corresponding collection and reaction device 3 through each discharge port 223 for reaction. At the same time, the magnetic suction element 21 in the distribution chamber 221 is energized, adsorbing magnetic foreign objects in the material. After the distribution chamber 221 has finished distributing the material and the multiple discharge ports 223 are closed, the magnetic suction element 21 switches to the de-energized state, the adsorbed magnetic foreign objects fall off, and air is introduced through the air inlet for backflushing. All magnetic foreign objects and calcium carbide dust are discharged from the foreign object discharge port 222.

[0024] Therefore, the aforementioned calcium carbide feeding system can, on the one hand, replace manual labor in material transfer and distribution. The material distribution device 2 can distribute the material into multiple collection reaction devices 3, achieving efficient material feeding and meeting the actual needs of large-scale continuous production. On the other hand, it can remove magnetic foreign objects from the material before the reaction, effectively reducing the risk of acetylene combustion or even explosion caused by mechanical sparks generated by friction between magnetic foreign objects and the inner wall of the collection reaction device 3.

[0025] In alternative implementations, such as Figure 1 As shown, the transfer device 1 includes a conveyor 11 and a first hopper 12.

[0026] The feed end of the conveyor 11 is connected to the upstream crushing device to receive the crushed calcium carbide material. The discharge end of the conveyor 11 is connected to the feed inlet of the first silo 12, so that the material enters the first silo 12 for temporary storage under gravity or mechanical propulsion. The first silo 12, as a buffer storage unit, can form a material flow regulation range between the crushing device and the distribution device, avoiding material supply interruption or overflow due to mismatch between the rhythm of the preceding and following processes, thereby ensuring the continuous and stable operation of the entire feeding system.

[0027] Specifically, the conveyor 11 can be a screw conveyor, belt conveyor or bucket elevator, etc., suitable for continuous conveying of powdery solid materials, and can stably and continuously transfer the crushed calcium carbide material from the crushing section to the subsequent feeding system.

[0028] Preferably, the conveyor 11 includes a scraper conveyor belt.

[0029] Furthermore, a first valve 4 is installed between the unloading end of the first hopper 12 and the feeding end of the distribution device 2. The first valve 4 can be a controllable valve structure such as a pneumatic slide valve, an electric ball valve, or a gate valve, and its opening and closing action is precisely controlled by the control system according to the working cycle of the distribution device 2 and the material demand. By controlling the opening and closing of the first valve 4, the time and flow rate of material flowing to the distribution chamber 221 can be precisely regulated, ensuring that the amount of material supplied to the distribution chamber 221 each time is appropriate, preventing overload or idling, and improving the safety and efficiency of system operation.

[0030] The above-described embodiment, by setting up a transfer device 1 consisting of a conveyor 11, a first silo 12 and a first valve 4, not only realizes the automated transfer and buffer storage of calcium carbide materials from the crushing stage to the reaction stage, but also improves the controllability and safety of the system operation through valve control, providing a reliable guarantee for subsequent efficient material distribution and clean feeding.

[0031] In alternative implementations, such as Figure 1 As shown, the first silo 12 is equipped with a first weighing sensor 13 and / or a first level gauge assembly 14 to realize real-time monitoring and automated control of the storage status of calcium carbide material in the first silo 12.

[0032] Specifically, the first weighing sensor 13 is installed on the support structure of the first silo 12, for example, on the load-bearing beam at the top of the first silo 12, to collect the total weight information of the first silo 12 and the materials inside in real time. The weight data is fed back to the control system, such as a PLC or DCS system, through a signal transmission module, thereby realizing the accurate measurement of the mass of the materials in the first silo 12.

[0033] In a preferred embodiment, when the first weighing sensor 13 detects that the weight of the material in the first hopper 12 has reached a preset upper limit, such as 10 tons, the control system generates a stop feeding command to control the conveyor 11 to stop running and prevent the hopper from being overloaded.

[0034] Specifically, the first level gauge assembly 14 includes an independently configured first level gauge 141 and a second level gauge 142, which are arranged vertically at intervals on the side wall of the first silo 12. The first level gauge 141 is located at a higher position to detect high level conditions, while the second level gauge 142 is located at a lower position to detect low level conditions. The first level gauge 141 and the second level gauge 142 can be any of the following types of level gauges: radio frequency admittance type, ultrasonic type, tuning fork type, or radar type. The selection is based on the on-site working conditions and media characteristics to ensure stable and reliable measurement.

[0035] During actual operation, the control system makes comprehensive judgments and performs linkage control based on multiple signals from the first weighing sensor 13 and the first level gauge assembly 14. For example, when the first weighing sensor 13 detects that the material weight reaches 10 tons or the first level gauge 141 issues a high level alarm signal, it is considered that the silo is full, and the control system automatically shuts down the conveyor 11 and suspends the feeding of material to the first silo 12; when the first weighing sensor 13 detects that the material weight is less than 3 tons or the second level gauge 142 issues a low level signal, it is considered that the material in the silo is insufficient, and the control system automatically starts the conveyor 11 to resume the feeding process.

[0036] The above implementation method not only improves the accuracy and redundancy of material monitoring by setting up a dual detection mechanism, but also enhances the security and stability of the system, avoiding problems such as overflow, idling or interruption of material supply caused by misjudgment, and ensuring the continuous, safe and efficient operation of the entire feeding system.

[0037] In an optional embodiment, the material distribution device 2 includes a housing 22 and a feeding mechanism 23. The housing 22 has a material distribution chamber 221, and the feeding mechanism 23 is at least partially disposed in the material distribution chamber 221 for guiding and distributing the calcium carbide material entering the material distribution chamber and realizing the orderly feeding of multiple material collection reaction devices 3.

[0038] Furthermore, the outer shell 22 is provided with a feed inlet connected to the unloading end of the transfer device 1, for receiving crushed calcium carbide material transported from upstream; at the same time, the outer shell 22 is also provided with a foreign matter discharge outlet 222 and multiple discharge outlets 223, for discharging separated magnetic foreign matter and distributing the purified material to downstream collection reaction devices 3, respectively.

[0039] In an optional embodiment, the feeding mechanism 23 includes a spiral feeding assembly arranged in a horizontal or inclined direction. Specifically, it includes a drive motor and a spiral shaft connected to the drive motor. By adjusting the rotation speed or start-stop sequence of the spiral shaft, quantitative diversion and conveying to different discharge ports 223 can be achieved.

[0040] In another preferred embodiment, the feeding mechanism 23 includes a plurality of spiral feeding components, such as... Figure 2 As shown, the material distribution chamber 221 may include multiple sub-cavities 2211 arranged in a stepped manner. The tail end of the upstream sub-cavity 2211 is connected to the head end of the downstream sub-cavity 2211. Each sub-cavity 2211 is independently equipped with a screw feeding assembly. The screw feeding assembly specifically includes a drive motor and a screw shaft connected to the drive motor. The screw shaft is rotatably connected to the outer shell 22 forming the sub-cavity, and the drive motor is installed outside the outer shell 22. The stepped arrangement of the sub-cavities 2211 provides clearance space for the installation of the drive motor, thereby facilitating the connection between the drive motor and the end of the screw shaft.

[0041] In addition, each sub-cavity 2211 has a discharge port 223 below it. For example, when there are three sub-cavities 2211, there are three corresponding aggregate reaction devices 3, namely the first aggregate reaction device, the second aggregate reaction device, and the third aggregate reaction device. When the first aggregate reaction device, which is close to the feed end of the outer shell 22, needs to be fed, it only needs to open the spiral feeding assembly in the sub-cavity 2211 above it; when the second aggregate reaction device in the middle needs to be fed, it needs to open the spiral feeding assembly in the sub-cavity 2211 above the first and second aggregate reaction devices, and close the feed end of the first aggregate reaction device; when the third aggregate reaction device, which is far from the feed end of the outer shell 22, needs to be fed, it needs to open all the spiral feeding assemblies, and close the feed ends of the first and second aggregate reaction devices.

[0042] In alternative implementations, such as Figure 1 As shown, the air inlet and the foreign object outlet 222 are located at opposite ends of the outer casing 22.

[0043] When the magnetic suction component 21 is de-energized and releases the magnetic foreign objects it has attracted, an external air source introduces nitrogen gas into the dispensing chamber 221 through the air inlet. The airflow flows along the length of the outer shell 22 from the air inlet end to the end where the foreign object discharge outlet 222 is located, forming a directional purging airflow. This airflow carries the detached magnetic foreign objects and the calcium carbide dust attached to the chamber wall together towards the foreign object discharge outlet 222, and finally discharges them from the outlet.

[0044] The above layout facilitates the formation of a smooth and efficient airflow channel during backflushing, avoiding the generation of dead zones or vortex areas, thereby significantly improving the efficiency of dust removal and foreign matter removal.

[0045] In alternative implementations, such as Figure 1 As shown, the calcium carbide feeding system also includes a second valve 5, a third valve 6, and a collector 7. The air inlet is connected to the second valve 5 through a pipe, and the foreign matter discharge outlet 222 is connected to the collector 7 through the third valve 6.

[0046] The second valve 5 is a controllable valve, such as a solenoid valve or a pneumatic angle seat valve. Its opening and closing state is automatically adjusted by the control system according to the material distribution process stage. When the material distribution operation is completed and the magnetic suction component 21 is de-energized and releases the magnetic foreign matter it has adsorbed, the control system issues a command to open the second valve 5, allowing compressed gas to enter the material distribution chamber 221 through the air inlet, forming a directional airflow. This airflow then reverses the flow to sweep away the magnetic foreign matter and attached calcium carbide dust remaining on the chamber wall and the surface of the magnetic suction component, promoting the complete removal of impurities and their flow to the foreign matter discharge port 222.

[0047] The third valve 6 is also a controllable valve. When it is opened, it works in conjunction with the second valve 5 to remain closed before the backflushing airflow takes effect, so as to maintain the sealed environment of the material distribution chamber 221. When the backflushing starts or slightly earlier, it opens to ensure that impurities can be smoothly discharged into the collector 7.

[0048] Of course, the two valves mentioned above can also be manually operated.

[0049] In alternative implementations, such as Figure 1 As shown, the magnetic attachment 21 is connected to the top of the inside of the housing 22.

[0050] The aforementioned magnetic attractor 21 can adopt an electromagnet structure, including an iron core and an excitation coil wound around the outer periphery of the iron core. When energized, it generates a strong magnetic field to attract magnetic foreign objects that enter the distribution chamber 221 along with the crushed calcium carbide material. When the power is cut off, the magnetic field disappears, realizing the automatic detachment of the magnetic foreign objects.

[0051] Placing the magnetic suction component 21 at the top inside the outer casing 22 facilitates the effective attraction of magnetic foreign objects by the upper magnetic field under the influence of gravity and inertia as the material enters from the feed inlet and flows along the distribution chamber 221, thereby improving the impurity removal efficiency. Simultaneously, this arrangement avoids interference between the magnetic suction component 21 and the operation of the lower feeding mechanism 23, ensuring smooth material conveying and reliable equipment operation.

[0052] In alternative implementations, such as Figure 1 As shown, the aggregate reaction device 3 includes a second silo 31, a fourth valve 32, and a generator 33.

[0053] The second silo 31 serves as an intermediate storage and buffer unit. Its feed end can be connected one-to-one with the discharge port 223 of the distribution device 2 via the seventh valve 10 to receive the purified calcium carbide material distributed by the distribution chamber 221. The discharge end of the second silo 31 is provided with a discharge port and is connected to the feed end of the generator 33 via the fourth valve 32.

[0054] The seventh valve 10 and the fourth valve 32 are controllable opening and closing elements, preferably pneumatic or electric gate valves, ball valves, or butterfly valves, which can realize timed or quantitative control of material feeding according to the needs of the production process. By adjusting the opening and closing of the seventh valve 10, it is possible to control whether the second hopper 31 receives material from the distributing device 2; by adjusting the opening and closing of the fourth valve 32, the amount of calcium carbide material entering the generator 33 can be precisely controlled, avoiding violent and uncontrolled reaction due to excessive instantaneous feeding, thereby ensuring the safety and stability of the reaction process.

[0055] In addition, generator 33 is the core reaction vessel for the chemical reaction between calcium carbide and water to generate acetylene gas. When the fourth valve 32 is opened, the calcium carbide material in the second hopper 31 falls into generator 33, where it comes into contact with water and undergoes a hydrolysis reaction to generate acetylene gas and the byproduct calcium hydroxide.

[0056] In alternative implementations, such as Figure 1 As shown, the generator 33 has an air inlet and an air outlet. The calcium carbide feeding system also includes a fifth valve 8 connected to the air inlet via a pipe, and a sixth valve 9 connected to the air outlet via a pipe.

[0057] Before feeding calcium carbide into generator 33, first open the fifth valve 8 to allow nitrogen gas to enter the generator 33 through the inlet; simultaneously open the sixth valve 9 to allow the existing gas in generator 33 to be discharged through the outlet via the pipeline, thus completing the nitrogen purging and replacement process. Under normal circumstances, nitrogen should be continuously introduced for about 20 minutes before continuing the calcium carbide feeding operation.

[0058] The above-described implementation method achieves safe pretreatment of the atmosphere inside the reactor, effectively eliminating the risk of combustion and explosion that may be caused by the mixing of oxygen and acetylene gas, and improving the inherent safety of the entire calcium carbide feeding and reaction system.

[0059] In alternative implementations, such as Figure 1 As shown, the second silo 31 is equipped with a second weighing sensor 34 and / or a second level gauge assembly 35 to realize real-time monitoring and automated control of the storage status of calcium carbide material in the second silo 31, so that the amount of calcium carbide participating in the reaction is more accurate.

[0060] Specifically, the second weighing sensor 34 is installed on the support structure of the second silo 31, for example, on the load-bearing beam at the top of the second silo 31, to collect the total weight information of the second silo 31 and its internal materials in real time. The weight data is fed back to the control system, such as a PLC or DCS system, through a signal transmission module, thereby realizing accurate measurement of the mass of the materials in the second silo 31.

[0061] In a preferred embodiment, when the second weighing sensor 34 detects that the weight of the material in the second hopper 31 has reached a preset upper limit, such as 2 tons, the material distribution device 2 and the corresponding seventh valve 10 are closed.

[0062] Specifically, the second level gauge assembly 35 includes independently configured third level gauge 351 and fourth level gauge 352, which are arranged vertically at intervals on the side wall of the second silo 31. The third level gauge 351 is located at a higher position to detect high level conditions, while the fourth level gauge 352 is located at a lower position to detect low level conditions. The third level gauge 351 and fourth level gauge 352 can be any of the following types of level gauges: radio frequency admittance type, ultrasonic type, tuning fork type, or radar type. The selection is based on the on-site working conditions and media characteristics to ensure stable and reliable measurement.

[0063] During actual operation, the control system performs comprehensive judgment and linkage control based on multiple signals from the second weighing sensor 34 and the second level gauge assembly 35. For example, when the second weighing sensor 34 detects that the material weight reaches 2 tons or the third level gauge 351 issues a high level alarm signal, it is considered that the silo is full, and the control system automatically closes the dispensing device 2 and the corresponding seventh valve 10; when the second weighing sensor 34 detects that the material weight is less than 0.1 tons or the fourth level gauge 352 issues a low level signal, it is considered that the silo is insufficient, and the control system automatically opens the dispensing device 2 and the corresponding seventh valve 10 to realize material feeding.

[0064] The aforementioned calcium carbide feeding system facilitates continuous feeding of calcium carbide. From calcium carbide crushing to calcium carbide conveying, a fully enclosed system and a fully automated process can be adopted, avoiding long-term exposure of personnel to dangerous environments.

[0065] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
