Description

Technical Field

[0001] This utility model belongs to the field of calcium carbide production technology, specifically relating to a novel energy-saving calcium carbide furnace bottom structure. Background Technology

[0002] Calcium carbide production involves feeding a specific ratio of raw materials (semi-coke and lime) into a submerged arc furnace, where an electric current causes the materials to react and produce calcium carbide. Because calcium carbide production is energy-intensive, the furnace bottom structure directly affects the current distribution and chemical reaction efficiency within the furnace.

[0003] Traditional calcium carbide furnaces use a carbon brick lining structure for the furnace bottom. Due to the high temperature (approximately 2200℃) of the furnace bottom and the ferrosilicon produced during the production process, the furnace bottom is often burned through or the high-temperature ferrosilicon flows out from the gaps in the carbon bricks, causing perforation and damage to the furnace bottom. At the same time, after long-term use, the furnace bottom structure changes and burns, resulting in uneven current distribution at the furnace bottom, which reduces the production efficiency of the calcium carbide furnace and affects economic benefits. Utility Model Content

[0004] The purpose of this utility model is to provide a new type of energy-saving furnace bottom structure for calcium carbide furnaces, which aims to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: It includes an outer shell, with an electrode plate extending through the surface of the outer shell. The electrode plate is fitted with a slag cleaning assembly. The slag cleaning assembly includes a servo motor, which is connected to a hinged connecting rod via an output shaft. The hinged connecting rod is formed by two connecting plates rotating around a straight shaft at one end. The other end of the hinged connecting rod is fixedly connected to a slag cleaning disc. A support connecting rod is installed on the outer surface of the slag cleaning disc, and the slag cleaning disc is fitted with a rotating assembly. The rotating assembly includes an electric furnace pot fitted into the inner wall of the slag cleaning disc. A counterweight is provided on the top of the electric furnace pot, and a herringbone bridge is rotatably connected to the upper surface of the counterweight.

[0006] In a preferred embodiment of this utility model, a first bevel gear is fitted on the outer surface of the herringbone bridge, the teeth of the first bevel gear mesh with a second bevel gear, and a drive source is adapted to be installed on the end face of the second bevel gear.

[0007] As a preferred embodiment of this utility model, the inner cavity of the herringbone bridge is threaded with a screw, and the top of the screw is fitted into a slot in the outer shell.

[0008] As a preferred embodiment of this utility model, a sliding straight rod is installed on the lower surface of the outer shell. The sliding straight rod is symmetrically arranged, and the outer surface of the sliding straight rod slides in conjunction with the herringbone bridge.

[0009] In a preferred embodiment of this utility model, a connecting seat is fixedly connected to the side of the drive source, and the bottom of the connecting seat is fixed to the slag removal disc.

[0010] As a preferred embodiment of this utility model, the rotation range of the electric furnace can is inside the inner cavity of the outer shell, and the outer surface of the electric furnace can is coated with an antistatic layer.

[0011] As a preferred embodiment of this utility model, a support rod is installed on the outer surface of the slag removal disc, an adapter shaft is inserted into the end face of the support rod, a conical disc seat is rotatably fitted to the bottom of the adapter shaft, and a slag discharge disc is fixed on the outer surface of the adapter shaft.

[0012] In a preferred embodiment of this utility model, the guide bar is an integrally formed inwardly curved circular pillow bar, and the end face of the guide bar points towards the center of the lower slag pan.

[0013] Compared with the prior art, the beneficial effects of this utility model are: (1) Through the transmission cooperation of servo motor, hinged connecting rod and slag cleaning disc, the residue at the bottom of the electric furnace can be shaken and removed in time, avoiding the residue from remaining at the bottom of the electric furnace can for a long time, solving the problem of instability of the furnace bottom structure due to the presence of residue, realizing the self-cleaning effect of the electric furnace can, and also ensuring the original bottom structure of the electric furnace can, thereby making the current distribution of the electric furnace can more uniform, and significantly improving the calcium carbide production efficiency. Then, through the sliding cooperation of the herringbone bridge and sliding straight rod The combination provides stable support for the displacement of the A-frame bridge, making the vibration of the residue inside the electric furnace tank more even. Through the switching of forward and reverse power of the drive source and the transmission of the first and second bevel gears, the A-frame bridge can move back to its original position. This further allows the electric furnace tank, which is fixed to the A-frame bridge, to repeatedly move in the vertical direction. After multiple and repeated displacements, the residue inside the electric furnace tank will fall off due to inertia. The more displacement processes there are, the more the residue will vibrate, which helps to solve the problem of a large amount of residue remaining in the electric furnace tank during calcium carbide production.

[0021] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0022] This utility model embodiment proposes a novel energy-saving calcium carbide furnace bottom structure, including an outer shell 1; exemplarily, such as... Figures 1-3 As shown.

[0023] Electrode plates 2 are connected through the surface of the outer shell 1. The electrode plates 2 are fitted with a slag cleaning assembly 3. The slag cleaning assembly 3 includes a servo motor 31. The servo motor 31 is connected to a hinged connecting rod 32 through an output shaft. The hinged connecting rod 32 is formed by two connecting plates rotating together through a straight shaft at one end. The other end of the hinged connecting rod 32 is fixedly connected to a slag cleaning disc 33. A support connecting rod 34 is installed on the outer surface of the slag cleaning disc 33. The slag cleaning disc 33 is fitted with a rotating assembly 4. The rotating assembly 4 includes an electric furnace pot 41 fitted into the inner wall of the slag cleaning disc 33. A counterweight 42 is provided on the top of the electric furnace pot 41. A herringbone bridge 43 is rotatably connected to the upper surface of the counterweight 42.

[0024] The outer surface of the herringbone bridge 43 is fitted with a first bevel gear 44, the teeth of the first bevel gear 44 mesh with a second bevel gear 45, and the end face of the second bevel gear 45 is fitted with a drive source 48.

[0025] The inner cavity of the herringbone bridge 43 is threaded with a screw 46, and the top of the screw 46 is fitted into a slot in the outer shell 1.

[0026] Specifically, by installing electrode plates 2 through the outer shell 1, the furnace charge inside the electric furnace 41 can be reacted into calcium carbide, demonstrating the functionality of the equipment. Furthermore, through the transmission cooperation of the servo motor 31, the hinged connecting rod 32 and the slag cleaning disc 33, the residue at the bottom of the electric furnace 41 can be shaken and removed in time, preventing the residue from damaging the stability of the furnace bottom structure of the electric furnace 41 for a long time. Then, by installing a counterweight 42 on the top of the electric furnace 41 and rotating the counterweight 42 to connect the herringbone bridge 43, the herringbone bridge 43 can rotate on its own.

[0027] Furthermore, through the meshing transmission between the drive source 48, the first bevel gear 44 and the second bevel gear 45, a continuous rotational power source can be provided for the herringbone bridge 43. Then, the herringbone bridge 43 is threadedly connected to the screw 46, so that the herringbone bridge 43 is displaced along the thread surface of the screw 46, thereby causing the electric furnace pot 41 to move up and down. The residue inside can be shaken up and down, which is conducive to the timely removal of more residue.

[0028] A sliding rod 47 is mounted on the lower surface of the outer shell 1; for example, such as Figures 2-4 As shown.

[0029] The sliding rods 47 are arranged symmetrically, and the outer surface of the sliding rods 47 slides in contact with the herringbone bridge 43.

[0030] A connecting seat 49 is fixedly connected to the side of the drive source 48, and the bottom of the connecting seat 49 is fixed to the slag removal disc 33.

[0031] Specifically, the sliding cooperation between the herringbone bridge 43 and the sliding rod 47 provides stable support for the displacement of the herringbone bridge 43, making the vibration amplitude of the residue inside the electric furnace pot 41 more even. Furthermore, the forward and reverse power switching of the drive source 48 allows the herringbone bridge 43 to move back to its original position, further enabling the electric furnace pot 41, which is fixed to the herringbone bridge 43, to repeatedly move in the vertical direction. After multiple and repeated displacements, the residue inside the electric furnace pot 41 will fall off due to inertia. The more displacement processes there are, the more the residue vibrates, allowing the electric furnace pot 41 to maintain its original cleanliness. The original bright structure of the furnace bottom will not change significantly, solving the problem of burn-out inside the electric furnace pot 41 and overcoming the problem of uneven current distribution at the furnace bottom.

[0032] The rotation range of the electric furnace tank 41 is within the inner cavity of the outer shell 1; for example, such as... Figures 3-4 As shown.

[0033] The outer surface of the electric furnace tank 41 is coated with an antistatic layer.

[0034] The end face of the support rod 34 is inserted with an adapter shaft 35. The bottom of the adapter shaft 35 is rotatably fitted with a conical disc seat 36. A slag discharge disc 37 is fixed on the outer surface of the adapter shaft 35. A slag guide bar 38 is provided on the surface of the slag discharge disc 37. The slag guide bar 38 is distributed in a ring array.

[0035] Specifically, by coating the surface of the electric furnace pot 41 with an antistatic layer, the safety of the surface of the electric furnace pot 41 can be improved. Furthermore, the slag discharge plate 37 can rotate autonomously through the rotation support of the adapter shaft 35. It is worth noting that the driving force of the slag discharge plate 37 is provided by the servo motor 31, while the power of the electric furnace pot 41 is provided by the drive source 48. The different rotation frequencies between the two allow for a larger range of slag vibration. Finally, the slag is guided out through the guide bar 38, thus solving the problem of long-term slag retention damaging the electric furnace pot 41.
