[0002] Calcium carbide is an important inorganic compound with wide applications in chemical, metallurgical, and other fields. In the calcium carbide production process, the batching station is a crucial link in the raw material transportation system of the calcium carbide furnace, responsible for the distribution and transfer of raw materials. The batching station's silos store fuels, including semi-coke. Due to its high combustion temperature, low impurities, and low pollution, semi-coke plays a vital role as a combustion feedstock in calcium carbide production.

[0003] During the production process, semi-coke is conveyed to a silo for storage via a conveyor belt. During storage, the temperature of the semi-coke itself remains high. When feeding the semi-coke from the silo into the vibrating feeder, the high temperature of the semi-coke, typically between 250 and 400 degrees Celsius, often causes the soft connection between the vibrating feeder and the silo to burn, leading to a fire risk and posing a threat to people's lives and property. Utility Model Content

[0037] In the production of calcium carbide, vibrating feeders are generally used to uniformly supply raw materials and fuels. Because vibrating feeders vibrate during operation, flexible connections are often required between the discharge port and the feed pipe to ensure proper vibration. However, during the storage of semi-coke in the silo, the temperature of the semi-coke can range from 250 to 400 degrees Celsius due to the various components within the semi-coke itself. During the feeding process, the high temperature of the semi-coke often causes the flexible connections to burn out due to friction and high temperatures, potentially leading to combustion and posing a fire risk that threatens people's lives and property.

[0038] To address the technical problems existing in the prior art, firstly, this utility model provides a semi-coke feeding device, see [link to previous document]. Figure 1 and Figure 2 The semi-coke feeding device includes at least a silo 1, a vibrating feeder 2, and a feeding pipe 3; the silo 1 stores semi-coke; the vibrating feeder 2 includes a body 21 and a feed pipe 22, the feed pipe 22 being fixedly installed above the body 21; the feeding pipe 3 includes an upper end 31 and a lower end 32, the upper end 31 being connected to the silo 1, and the lower end 32 being provided with a metal connector 4; the metal connector 4 is inserted into the feed pipe 22.

[0039] In this embodiment, semi-coke is stored in silo 1, and semi-coke is evenly fed out of silo 1 by vibrating feeder 2. During the process of feeding semi-coke from silo 1 through feeding pipe 3, the high-temperature semi-coke enters feeding pipe 3 through the upper end 31 and moves along feeding pipe 3 to the lower end 32. Since the lower end 32 is provided with metal connector 4, and the metal connector 3 is inserted into the feed pipe 22 of vibrating feeder 2, it plays a connecting role, allowing the high-temperature semi-coke to enter vibrating feeder 2 through metal connector 4. Therefore, there is no need to set up a flexible connection to connect the lower end 32 of feeding pipe and feed pipe 22, thus avoiding the technical problem of high-temperature semi-coke causing the flexible connection to burn out or even causing a fire risk.

[0040] Optionally, the metal connector 4 in this utility model includes a flange 41 and a metal pipe 42. The metal pipe 42 is fixedly connected to the lower end 31 of the feed pipe 3 through the flange 41, and one end of the metal pipe 42 is connected to the lower end 32, while the other end is inserted into the feed pipe 22.

[0041] In this embodiment, the metal connector 4 includes a flange 41 and a metal pipe 42. The metal pipe 42 is fixedly connected to the lower end 31 of the feed pipe 3 through the flange 41. One end of the metal pipe 42 is connected to the lower end 32, and the other end is inserted into the feed pipe 22, thereby realizing the connection between the feed pipe 3 and the feed pipe 22. This facilitates the entry of semi-coke into the vibrating feeder 2. Furthermore, since the connection is made through the metal pipe 42, the high-temperature semi-coke will not be burned, thus avoiding the risk of fire.

[0042] Furthermore, the diameter of the feed pipe 3 can be 500 mm, and the diameter of the metal pipe can be 450 mm, to facilitate the rapid falling of semi-coke.

[0043] Furthermore, the metal pipe 42 can be selected as a metal flexible pipe, a metal corrugated pipe, etc., to have a certain range of deformation. During the vibrating feeding process of the vibrating feeder 2, the metal pipe 42 can be deformed to avoid being damaged by hard impacts.

[0044] Optionally, there is a gap between the metal tube 42 and the inner wall of the feed tube 22 in this invention.

[0045] In this embodiment, there is a gap between the metal pipe 42 and the feed pipe 22 to prevent hard collisions between the metal pipe 42 and the feed pipe 22 during the process of the vibrating feeder 2 conveying the semi-coke by vibration, which could cause damage or cause the discharge pipe 3 to shake and lead to a safety accident.

[0046] Optionally, the distance between the inner wall of the metal tube 42 and the feed tube 22 in this invention is 8 mm to 25 mm.

[0047] In this embodiment, the distance between the inner wall of the metal tube 42 and the feed tube 22 is 8 mm to 25 mm. Since the vibration range of the vibrating feeder 2 is generally between 5 mm and 20 mm and is adjusted according to the feeding requirements, the distance between the metal tube 42 and the feed tube 22 is set between 8 mm and 25 mm to prevent the inner wall of the feed tube 22 from colliding with the metal tube 42 during the vibrating feeding process. Specifically, the distance between the metal tube 42 and the feed tube 22 can be selected as 8 mm, 10 mm, 15 mm, 20 mm, or 25 mm.

[0048] Optionally, the length of the metal tube 42 inserted into the feed tube 22 in this utility model is 25 cm to 40 cm.

[0049] In this embodiment, the length of the metal tube 42 inserted into the feed tube 22 is 25 cm to 40 cm, so that the high-temperature semi-coke can enter the vibrating feeder 2 more deeply. This avoids the semi-coke being shaken out by the vibration of the vibrating feeder 2 when the insertion is too shallow, which would cause safety risks and improve the safety of the semi-coke feeding device.

[0050] Optionally, the metal tube 42 in this utility model can be either a stainless steel tube or a high-temperature alloy tube.

[0051] In this embodiment, the metal tube 42 is either a stainless steel tube or a high-temperature alloy tube, to possess wear-resistant and high-temperature-resistant properties, thereby improving the service life of the semi-coke feeding device. It should be noted that those skilled in the art can select the specific material of the metal tube 42 according to actual production and usage requirements; this embodiment only provides a preferred implementation.

[0052] Optionally, the semi-coke feeding device of this utility model also includes a fireproof cloth, which is wrapped around the lower end 32 of the feeding pipe 3, the metal connector 4 and the feed pipe 22.

[0053] In this embodiment, fireproof cloth is wrapped around the lower end 32 of the feeding pipe 3, the metal connector 4, and the feed pipe 22 to prevent high-temperature debris and slag generated during the feeding process of semi-coke from flying out from the gap between the metal pipe 42 and the feed pipe 22, thus avoiding the technical problem of safety risks caused by the flying out of high-temperature debris and slag.

[0054] Optionally, the vibrating feeder body 21 of this utility model includes a vibrating plate 211 and a discharge pipe 212; the feed pipe 212 is fixedly arranged above the vibrating plate 211; the discharge pipe 212 is arranged on the lower side of the vibrating plate 211 and is connected to the weighing hopper 5.

[0055] In this embodiment, the body 21 of the vibrating feeder includes a vibrating plate 211 and a discharge pipe 212. The feed pipe 212 is fixedly arranged above the vibrating plate 211 to allow the semi-coke to enter the vibrating plate 211 and vibrate forward on the vibrating plate 211. The discharge pipe 212 is arranged on the lower side of the vibrating plate 211 and is connected to the weighing hopper 5 so that the semi-coke on the vibrating plate 211 is evenly transported to the weighing hopper 5. After the required amount is reached, the semi-coke is sent to the calcium carbide furnace for combustion again through a conveyor belt or other device.

[0056] Optionally, the feeding pipe 3 in this utility model is provided with a feeding valve 33.

[0057] In this embodiment, a discharge valve 33 is provided on the discharge pipe 3 to control the discharge of semi-coke in the silo 1.

[0058] Secondly, this utility model also provides a calcium carbide production system, which includes a calcium carbide furnace and any of the above-mentioned semi-coke feeding devices; and the semi-coke feeding device is connected to the calcium carbide furnace.

[0059] In this embodiment, a calcium carbide production system is provided, including a calcium carbide furnace and any of the above-mentioned semi-coke feeding devices. It should be noted that the semi-coke feeding device in this embodiment is the same as any of the above-mentioned semi-coke feeding devices, and its beneficial effects and implementation methods are similar, so they will not be described in detail here. The calcium carbide production system provided by this utility model solves the technical problem that the high-temperature semi-coke in the calcium carbide production process will burn the flexible connection and cause a fire risk.

[0060] In the description of this specification, the references to terms such as "one embodiment," "some embodiments," "illustrative embodiment," "example," "specific example," or "some examples," etc., indicate that a specific feature, structure, material, or characteristic described in connection with that embodiment or example is included in at least one embodiment or example of the present invention. In this specification, the illustrative expressions of the above terms do not necessarily refer to the same embodiment or example. Furthermore, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples.

[0061] Although embodiments of the present invention have been shown and described, those skilled in the art will understand that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the claims and their equivalents.
