Description

Technical Field

[0001] The utility model relates to the technical field of calcium carbide furnaces, and more specifically to a water-cooling sealing sleeve of a calcium carbide furnace. Background Art

[0002] The calcium carbide furnace is the main equipment for producing calcium carbide. In the calcium carbide furnace, the high temperature generated by the electric arc causes the charge to melt and react to produce calcium carbide. The size of the reaction space in the furnace is determined by the size and distance of its electrodes and the range of action of the arc. The distance between the circular electrodes is directly proportional to their diameter, and the electrode diameter varies with the capacity of the furnace. The calcium carbide furnace requires a sealing sleeve for cooling.

[0003] The patent document with publication number CN204612479U in the prior art provides a water-cooled sealing sleeve for a calcium carbide furnace. Since the thermal conductivity and electrical conductivity of the thermal barrier insulation layer of this device are very low, the use of the thermal barrier insulation layer can reduce the temperature of the metal substrate by 150-200°C, improve the structural strength of the substrate material, and reduce thermal deformation stress and temperature gradient. Since the thermal barrier insulation layer has good insulation properties, the furnace charge attached to the water-cooled sealing sleeve cannot form sparks between the furnace cover and the water-cooled sealing sleeve when turning the material, thereby avoiding water leakage caused by sparks.

[0004] Although the device has many beneficial effects, the following problems still exist: during the use of the device, the cooling effect on the calcium carbide furnace is not good enough and the temperature reduction is not uniform enough; secondly, the insulation effect of the device relying solely on the thermal barrier insulation layer is not good during use and needs to be improved. In view of this, we propose a water-cooled sealing sleeve for the calcium carbide furnace. Utility Model Content

[0027] See also Figure 1-5 ,The utility model provides a technical solution:

[0028] A water-cooled sealing sleeve for a calcium carbide furnace comprises a large water-cooling sleeve 1, a sealing sleeve 2 being threadedly connected to the top of the large water-cooling sleeve 1, a base 3 being fixedly provided at the bottom of the large water-cooling sleeve 1, a water-cooling component 4 being fixedly provided inside the large water-cooling sleeve 1, the water-cooling component 4 comprising a water inlet 401, an inner liner 402 being fixedly provided inside the large water-cooling sleeve 1, a plurality of first baffles 403 being fixedly provided on the circumferential outer wall of the inner liner 402, a second baffle 404 being clamped on the side wall of the first baffle 403, a through hole 405 being provided on the top of the plurality of first baffles 403, a chamber 406 being provided on the top of the first baffle 403, a water storage tank 407 being fixedly provided on the top of the large water-cooling sleeve 1, a water outlet 408 being fixedly provided on the side wall of the water storage tank 407, and insulating components 5 being bonded to both ends of the top of the large water-cooling sleeve 1. The utility model arranges a large water-cooling sleeve on the outer circumferential wall of the calcium carbide furnace, inputs cooling water through the water inlet 401 to cool the calcium carbide furnace, and causes the hot water heated by the calcium carbide furnace to rise due to the principle of thermal expansion and contraction, and enters the next chamber 406 through the through hole 405, so as to make the cooling more uniform and improve the cooling effect, and the heated cooling water is discharged through the water outlet 408.

[0029] Specifically, the insulation assembly 5 includes a cover plate 501, with an insulation plate 502 bonded to the top of the cover plate 501, a pressure plate 503 bonded to the top of the insulation plate 502, a bolt 504 threadedly connected to the top of the pressure plate 503, and an insulating sleeve 505 sleeved around the outer wall of the bolt 504. By screwing in the bolt 504, the cover plate 501 and the pressure plate 503 are secured, thereby connecting the large water-cooling jacket 1 and the sealing sleeve 2. The cover plate 501 abuts the large water-cooling jacket 1, the insulation plate 502 improves the insulation effect, and the insulating sleeve 505 prevents the bolt 504 from conducting electricity.

[0030] Furthermore, the plurality of first baffles 403 are equidistantly arranged, and the plurality of through holes 405 are not located on the same vertical line. The plurality of through holes 405 not being located on the same vertical line prevents the cooling water from rising rapidly into the next chamber 406, thereby avoiding insufficient cooling.

[0031] It is worth noting that washers 506 are sleeved on the top and bottom of the outer wall of the bolt 504. The washers 506 are made of nitrile rubber. The nitrile rubber washers 506 protect the surfaces of the cover plate 501 and the pressure plate 503 from being scratched by the nut, disperse the pressure, and further improve the insulation performance.

[0032] It is worth noting that the first baffle 403 is fixed with a clamping block 6 on both ends of the sidewall, and the second baffle 404 is provided with a clamping interface 7 on both ends of the sidewall. Screw holes 8 are provided on the top of the second baffle 404 and the top of the clamping block 6. By inserting the clamping block 6 into the clamping interface 7 and screwing the screw into the screw hole 8, the first baffle 403 and the second baffle 404 are easily connected and used.

[0033] In addition, the size and position of the card block 6 match those of the card interface 7, and the inner diameters of the first baffle 403 and the second baffle 404 are consistent with the diameter of the inner liner 402. The first baffle 403 and the second baffle 404 having the same inner diameter as the inner liner 402 facilitate better fit to the inner liner 402 and improve sealing.

[0034] Working principle: When this device is needed to be used as a water-cooled sealing sleeve for a calcium carbide furnace, the large water-cooling sleeve 1 is installed on the outer circumferential wall of the calcium carbide furnace, the sealing sleeve 2 is installed on the top of the large water-cooling sleeve 1, the cover plate 501, the insulating plate 502, and the pressure plate 503 are glued to the top of the large water-cooling sleeve 1 in sequence, and the bolts 504 are screwed in. Washers 506 are installed on the top and bottom of the outer circumferential wall of the bolts 504, the card block 6 is inserted into the card interface 7, the screws are screwed into the screw holes 8, and the first baffle 403 and the second baffle 404 are connected in combination, and cooling water is input into the water inlet 401. After the cooling water is heated, it rises through the through hole 405 and enters the next chamber 406. The fully heated cooling water is stored in the water tank 407 and discharged from the water outlet 408.
