Description

Technical Field

[0001] This utility model relates to the field of calcium carbide cooling technology, and in particular to a furnace tapping machine drill rod and residue recovery device that facilitates slag removal. Background Technology

[0002] The calcium carbide tapping machine mainly functions as an opening and closing device in the calcium carbide furnace. It is an important piece of equipment on the furnace. The tapping machine connects the furnace to the downstream equipment and plays a good role in cooling and transition. Opening the furnace hole is to release the molten calcium carbide that has been electrochemically smelted at high temperature. Closing the hole is necessary because the flow rate of the molten calcium carbide is slowed down due to slag adhesion during the outflow process, which affects the tapping time. During the closing operation, the tapping machine's drill rod extends to repeatedly poke and pull the furnace hole and the flow channel of the furnace body to clear the blockage. After the closing operation is completed, the tapping machine's drill rod retracts. Since the temperature of the calcium carbide furnace is as high as 1800 degrees Celsius or more, a lot of oxide scale will appear on the drill rod during actual production. Excessive accumulation of oxide scale or irregular falling off seriously affects the normal operation of the tapping machine. In the current technology, the oxide scale is usually removed by manually knocking or scraping it off. This operation method is prone to damaging the drill rod, and the disorderly falling oxide scale causes environmental pollution in the workshop. There is an urgent need to improve this method. Utility Model Content

[0004] The utility model discloses a furnace tapping rod for easy slag removal, comprising a base rod and a cone head. A central through hole is formed in the base rod, and several sliding grooves are evenly distributed on the outer circumference of the base rod. Several sliding plates matching the sliding grooves are connected to the end face of the cone head, and the sliding plates are slidably connected to the sliding grooves. A central column is coaxially connected to the cone head, and the central column is slidably connected to the central through hole. A sliding drive assembly is provided at the other end of the central column, and the sliding drive assembly is used to drive the sliding plates to slide against the sliding grooves.

[0005] Furthermore, the sliding drive assembly includes a sliding column connected to the central column, a spring groove is provided at one end of the base rod, the sliding column is slidably connected to the spring groove, a compression spring is fitted on the central column, one end of the compression spring contacts the bottom of the spring groove, the other end of the compression spring contacts the sliding column, a cover plate is fixedly covered at the opening of the spring groove, a threaded through hole is provided on the cover plate, and an adjusting bolt is screwed into the threaded through hole.

[0006] Furthermore, the sliding plate is arc-shaped, and the outer diameter of the sliding plate is the same as the diameter of the base rod.

[0007] Preferably, a residue recycling device is provided, which includes an inclined collection trough, a plurality of V-frames installed along the length of the collection trough, the V-frames being used to place the furnace tapping rod, and a support and a leg vertically connected to the bottom of the collection trough.

[0008] Furthermore, rollers are installed on the outriggers.

[0009] Furthermore, the top of the V-frame is pointed.

[0010] Furthermore, an insertion groove is provided on the inner wall at the end of the collection trough, and a baffle plate is inserted into the insertion groove.

[0011] The beneficial effects of this utility model are as follows: This utility model designs the drill rod in two parts and designs a sliding plate on the outer surface of the base rod to facilitate the automatic breakage and removal of the oxide scale on the surface of the drill rod after cooling, avoiding the need to knock or scrape the drill rod for cleaning, thus improving the service life of the drill rod. At the same time, a special collection tank is designed to recycle the detached residue, ensuring a clean workshop environment. This utility model is worth promoting and using.

Detailed Implementation

[0017] like Figure 1 , Figure 3 and Figure 4As shown, a furnace tapping machine drill rod for easy slag removal includes a base rod 1 and a cone head 2. A central through hole 6 is formed in the base rod 1. Several sliding grooves 5 are evenly distributed on the outer circumference of the base rod 1. Several sliding plates 4, matching the sliding grooves 5, are connected to the end face of the cone head 2. The sliding plates 4 are slidably connected to the sliding grooves 5. A central column 3 is coaxially connected to the cone head 2 and is slidably connected to the central through hole 6. A sliding drive assembly is provided at the other end of the central column 3. The sliding drive assembly is used to drive the sliding plates 4 to slide against the sliding grooves 5. The sliding drive assembly includes a sliding column 8 connected to the central column 3, a spring groove 7 formed at one end of the base rod 1, the sliding column 8 being slidably connected to the spring groove 7, a compression spring 17 fitted on the central column 3, one end of the compression spring 17 contacting the bottom of the spring groove 7, and the other end of the compression spring 17 contacting the sliding column 8, a cover plate 10 fixedly covering the opening of the spring groove 7, a threaded through hole formed on the cover plate 10, and an adjusting bolt 9 screwed into the threaded through hole; the sliding piece 4 is arc-shaped, and the outer diameter of the sliding piece 4 is the same as the diameter of the base rod 1.

[0018] like Figure 1 and Figure 2 As shown, a residue recycling device is provided, which includes an inclined collection tank 11. Several V-frames 15 are installed along the length of the collection tank 11. The V-frames 15 are used to place the tapping machine rod. A support 12 and a support leg 13 are vertically connected to the bottom of the collection tank 11. Rollers are installed on the support legs 13. In order to facilitate the pressure cutting action on the oxide scale, the top of the V-frame 15 is pointed. An insertion groove is opened on the inner wall of the end of the collection tank 11, and a baffle plate 16 is inserted into the insertion groove.

[0019] In practical use, such as Figures 1 to 4 As shown, after the furnace is finished, the drill rod with calcium carbide liquid adhering to its surface is placed on the V-frame 15 in the collection tank 11. Before reuse, the drill rod has cooled down. At this time, the adjusting bolt 9 can be turned to push the central column 3 and the sliding plate 4 outward, so that the sliding plate 4 and the base rod 1 are relatively displaced. At this time, the oxide scale on the surface of the drill rod is subjected to force and produces longitudinal cracks and breaks off. The drill rod can be rotated circumferentially at the same time. The sharp V-frame 15 can further cut the oxide scale laterally, further accelerating the breaking off of the oxide scale. The broken oxide scale is collected in the collection tank 11. When there is a lot of oxide scale in the collection tank 11, the push handle 18 can be pushed upward and the roller 14 can be used to move the oxide scale to the designated position and pull out the baffle plate 16 to discharge the oxide scale.

[0020] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
