Description

Technical Field

[0001] The present application relates to the technical field of calcium carbide furnace production equipment, and in particular to a ring bucket feeder for feeding calcium carbide furnace production. Background Art

[0002] The calcium carbide furnace is the primary equipment for producing calcium carbide. The high temperature generated by the electric arc causes the charge (quicklime and carbonaceous raw materials) to melt and react within the furnace, producing calcium carbide. During processing, the mixed material is added through an inlet or pipe at the top of the furnace. It is heated to approximately 2000°C in an open or closed furnace, where it reacts to produce calcium carbide. The charging process utilizes multiple conveyors to alternately transport the mixture of semi-coke and lime. However, the material can easily shift position during the feeding process, resulting in an uneven material mix. Furthermore, the complex structure of multiple conveyor belts increases the maintenance workload for on-site personnel.

[0040] The core of this application is to provide a ring bucket feeder for feeding calcium carbide furnace production. The ring bucket feeder has a simple structure and more uniform material distribution.

[0041] Figure 1 A top view of a ring bucket feeder provided in an embodiment of the present invention; Figure 2 A cross-sectional view of a ring bucket feeder provided in an embodiment of the present invention; Figure 3 A schematic diagram of the base structure provided by an embodiment of the present invention; Figure 4 A schematic diagram of the closed door opening mechanism provided by an embodiment of the present invention; Figure 5 6 is a schematic diagram of the door opening mechanism provided by an embodiment of the present invention; 7 is a schematic diagram of the door closer mechanism provided by an embodiment of the present invention; Figure 7 A schematic diagram of the structure of a feeding hopper provided in an embodiment of the present invention; Figure 8 A schematic diagram of the structure of a dust cover provided in an embodiment of the present invention; Figure 9 This is a schematic structural diagram of the traveling wheel mechanism provided in an embodiment of the present invention.

[0042] like Figure 1-9As shown, the ring bucket feeder provided in this embodiment is mainly used for feeding in the process of processing calcium carbide in a calcium carbide furnace. There is usually a silo for feeding above the calcium carbide furnace, and the material can be added to the silo through the ring bucket feeder. The ring bucket feeder for feeding the calcium carbide furnace provided in this embodiment includes a ring-shaped track body 1, and the track body 1 is located above the calcium carbide furnace. The driving device 3 installed on the ring bucket feeder body 2 is used to drive the ring bucket feeder body 2 to move along the track body 1. The driving device 3 is an existing common driving method, for example, a reducer drives a gear disc and drives a steering mechanism such as a gear installed on the ring bucket feeder body 2 to rotate. Among them, a walking wheel mechanism 101 is installed, and the walking wheel mechanism 101 is installed below the ring bucket feeder body 2, and the walking wheel mechanism 101 slidably connected to the track body 1 can be set to be elevated. As shown Figure 8 As shown, as a further solution, the walking wheel mechanism includes a walking shaft 71, support seats 72 are installed at both ends of the walking shaft 71, and a wheel body 73 is installed on the inner side of the support seat 72, and the wheel body 73 is slidably connected to the track body 1.

[0043] In this embodiment, if Figure 6 As shown, as a further solution, the feeding hopper 4 includes a hopper body 41, the outer side of which is provided with a gear ring 42 adapted to the drive device 3, and the bottom of the hopper body 41 is provided with a sealing cover 43 mounted vertically downward. When the ring hopper feeder body 2 rotates, since the hopper body 41 is fixed to the ring hopper feeder body 2, when the drive device 1 drives the gear ring 42 to rotate, the ring hopper feeder body 2 also rotates along the track body 1.

[0044] In this embodiment, the feeding hopper 4 on the ring hopper feeder body 2 is filled with material, and the feeding hopper 4 is independently arranged in a ring shape and equidistantly arranged on the ring hopper feeder body 2. As a further solution, the number of feeding hoppers 4 is 54. In order to prevent foreign matter from entering the feeding hopper 4, a dust cover 102 is installed above each feeding hopper 4. Figure 7 As shown, as a further solution, the dust cover 102 includes a cover 63 fixed to the outer arc plate 61 and the inner arc plate 62. The inner arc plate 62 is fixedly connected to the outer arc plate 61 and the feeding hopper 4 on both sides. A cover plate 63 is installed between the outer arc plate 61 and the inner arc plate 62, and a feed port 631 is installed on the cover plate 63. In other words, the dust cover 102 composed of the outer arc plate 61, the inner arc plate 62 and the cover plate 63 can seal the top of the feeding hopper 4. When feeding is required, it is only necessary to connect a feed pipe to the feed port 631 to feed.

[0045] In this embodiment, a silo door 221 is movably mounted at the bottom of the ring hopper feeder body 2. When material is unloaded, the door opener mechanism is activated to open the silo door 221. During actual unloading, since each calcium carbide furnace's silo is equipped with a particle level sensor, and each silo is marked with a position sensor, when material is required, the control center rotates the loaded feeding hopper 4 above the silo and opens the silo door 221 via the door opener mechanism. The door opener mechanism is mounted at the bottom of each feeding hopper 4, and below each door opener mechanism is a door closer mechanism 111 for closing the silo door 221. The door closer mechanism 111 is mounted above the calcium carbide furnace. Furthermore, the door closer mechanism 111 acts as a buffer for the silo door 221, preventing it from being damaged by impact after opening.

[0046] If the ring hopper feeder body 2 is frequently unloaded during use, the silo door 221 is very likely to be damaged, requiring frequent replacement, which increases the workload of current staff. Therefore, the arrangement of the door closer mechanism 111 provided in this application significantly reduces the number of maintenance times for the silo door 221. As a further solution, the door opener mechanism includes a base 11 installed on the outside of the track body 1, and a door opening mechanism is provided on one side of the feeding hopper 4, and the door opening mechanism is located above the base 11; the base 11 includes two pads 12, and a bottom plate 13 is installed on the top of the two pads 12, and a first ear plate 131 is installed at one end of the bottom plate 13, and the first ear plate 131 is movably connected to the first connecting rod 133 through a first pin shaft 132, and the first connecting rod 133 is movably connected to the second connecting rod 135 through a second pin shaft 134, and the second connecting rod 135 is movably connected to the second ear plate 137 through a third pin shaft 136; a column plate 103 is installed at the other end of the bottom plate 13, and a fourth pin shaft 104 is provided on the column plate 103, and the upper portion of the column plate 103 The end is movably connected to the third ear plate 106 through the fifth pin shaft 105, and the third ear plate 106 and the second ear plate 137 are jointly installed with a top plate 138, and the second pin shaft 134 and the fourth pin shaft 104 are movably connected with a cylinder 139; the door opening mechanism includes a steering shaft 14, and side plates 141 are installed at both ends of the steering shaft 14, and a rotating wheel 142 is installed at the bottom of the side plate 141. A hook 143 is fixedly installed on the steering shaft 14, and the hook 143 is adapted to the lower hopper door installed at the bottom of the feeding hopper 4. A reset mechanism is also installed at both ends of the steering shaft 14; the reset mechanism includes a connecting plate 151 movably connected to the steering shaft 14, and one end of the connecting plate 151 is movably connected to a gravity block 152, and the gravity block 152 is connected to the ring bucket feeder body 2.

[0047] When the silo door 221 needs to be opened, the feeding hopper 4 moves to the top of the silo to be fed, and the control center (control system) starts the cylinder 139, which pushes the second connecting rod 135 and the first connecting rod 133 forward, thereby tilting the top plate 138 upward. Figure 5 As shown, at this point, the rotating wheel 142 moves upward from the inclined top plate 138. During this movement, the steering shaft 14 rotates counterclockwise, causing the hook 143 supporting the silo door 221 to rotate. The rotated hook 143 then disengages the silo door 221, leaving one end of the door 221 without support and causing it to fall downward onto the door closer mechanism 111. Once the door closer mechanism 111 is unloaded, the silo door 221 returns to a horizontal position. Similarly, the cylinder 139 gradually returns the top plate 138 to a horizontal position. As this position returns, the steering shaft 14 rotates clockwise, causing the hook 143 to rotate to the bottom of the silo door 221 for support. Furthermore, each door closer mechanism 111 corresponds to the number of door opener mechanisms.

[0048] In this embodiment, if Figure 5 As shown, as a further solution, the door closer mechanism 111 includes a door closer base 16, a door closer bottom plate 17, a door closer fixing frame 18 is installed on the door closer bottom plate 17, an elastic part 19 is installed between the door closer bottom plate 17 and the door closer fixing frame 18, and a door closer roller is installed on the door closer fixing frame 18; the door closer roller includes a first buffer roller group 201 and a second buffer roller group 202, the first buffer roller group 201 is located in front of the second buffer roller group 202, and the first buffer roller group 201 is two pulleys 5 arranged at an angle, and the second buffer roller group 202 is two pulleys 5 arranged in parallel.

[0049] As the silo door 221 falls, it first lands on the first buffer roller assembly 201, where it is cushioned. Then, as the hopper feeder moves forward, the silo door 221 moves onto the second buffer roller assembly 202 and is returned to its horizontal position by two parallel pulleys 5. The elastic portion 19 is a spring column or spring base that cushions the falling silo door 221.

[0050] To further enhance the buffering force, a third buffer roller assembly is further provided at the front end of the first buffer roller assembly. The third buffer roller assembly comprises a side rod 181 mounted on the door closer mounting bracket 18. The side rod 181 is provided with a front pulley 183 via a movable shaft 182. The provision of the front pulley 183 enhances the buffering force.

[0051] Compared with the prior art, the ring bucket feeder for feeding calcium carbide furnace production provided in this application includes a track body 1, on which a ring bucket feeder body 2 is installed, and the ring bucket feeder body 2 includes: a driving device 3, which is used to drive the ring bucket feeder body 2 to move along the track body 1; a walking wheel mechanism 101, which is installed below the ring bucket feeder body 2, and the walking wheel mechanism is slidably connected to the track body 1; a feeding hopper 4, which is multiple in number and is installed on the ring bucket feeder body 2 at equal distances; a door opener mechanism, which is installed at the bottom of each feeding hopper 4, and a door closer mechanism 111 is provided below each door opener mechanism, and the door closer mechanism 111 is installed above the calcium carbide furnace; a dust cover 102, which is installed above each feeding hopper 4.

[0052] Compared with the existing technology, the ring bucket feeder replaces multiple belts to convey materials alternately. Each material is placed in the feeding hopper and falls evenly from the bottom of the feeding hopper into the calcium carbide furnace, so the material is more evenly distributed. Moreover, compared with multiple running belts, the ring bucket feeder structure has fewer maintenance parts, reducing the maintenance workload and intensity of on-site personnel. At the same time, the unloading process of the ring bucket feeder is not prone to deviation, and the material ratio is more uniform.
