Description

Technical Field

[0001] The utility model relates to the technical field of furnace building, in particular to a material beating and compacting device used for furnace building operations. Background Art

[0002] During the construction of a medium-frequency melting furnace used for induction melting and gas atomization powder production, the quality of the crucible lining material compaction has a great impact on the life of the crucible. If the vibrating material is not tight, the crucible is very likely to crack, and even steel leakage may occur during melting. At present, pneumatic furnace building machines are mostly used for lining material knotting in medium and large-scale gas atomization powder production equipment. However, such pneumatic furnace building machines are usually not compatible with small-scale gas atomization powder production equipment. To ensure quality, small-scale gas atomization powder production equipment mostly adopts manual furnace building. The lining of the manually built furnace has good density, but manual work is easily affected by factors such as personal experience, resulting in unstable quality, poor uniformity, and high labor intensity. Therefore, there is an urgent need for a furnace knotting device that is highly versatile and can ensure knotting quality. Utility Model Content

[0026] See also Figure 1 This embodiment discloses a tamping device for furnace construction, which is mainly used for tying dry vibrating materials in the furnace lining during smelting furnace construction. The tamping device includes a support portion 1, a drive portion 2, and a ramming portion 3. The support portion 1 is used to support the entire device and is constructed as an annular support structure with a predetermined height. The drive portion 2 is connected to the support portion 1 and is configured to move in a circular manner along the annular support. The bottom end of the drive portion 2 is connected to the ramming portion 3, which can drive the ramming portion 3 to move in a circular manner and can also drive the ramming portion 3 to reciprocate to perform ramming operations.

[0027] Specifically, the support portion 1 includes a plurality of legs 11 and an annular frame 12 connected to the top ends of the legs 11. The legs 11 have a predetermined height to provide sufficient installation space and movement space for the driving portion 2 and the ramming portion 3. The annular frame 12 is constructed as an annular guide rail structure that roughly matches the diameter of the induction coil, and the driving portion 2 is slidably connected to the annular guide rail.

[0028] In this embodiment, the driving part 2 includes a pneumatic jackhammer 25 and a sliding part 21. The top end of the pneumatic jackhammer 25 is slidably connected to the annular guide rail through the sliding part 21. Under external force, the pneumatic jackhammer 25 can make a circular motion along the annular guide rail.

[0029] In a preferred embodiment, the support portion 1 further includes an annular motion drive member (not shown) disposed within the annular guide rail. This annular motion drive member is connected to the sliding portion 21 via a transmission member, and drives the sliding portion 21 and the pneumatic jackhammer 25 to perform annular motion along the annular guide rail. The drive member may be a servo motor coupled with a synchronous wheel, and the transmission member may be a synchronous belt, chain, or other transmission method. The annular motion drive structure is conventional and its structure is not described in detail herein.

[0030] In another more preferred embodiment, the sliding portion 21 adopts an electric hoist pulley with a relatively simple structure and small space. Figure 1 and Figure 2 The top of the pneumatic jackhammer 25 is fixedly connected to a jackhammer connecting plate 22, and the bottom end of the sliding portion 21 is connected to a pulley connecting plate 23. The jackhammer connecting plate 22 is connected to the pulley connecting plate 23, and the pneumatic jackhammer 25 is driven to perform circular motion via the electric hoist pulley. In this preferred embodiment, the pulley connecting plate 23 is provided with an elongated hole 24 along the radial direction of the annular guide rail. By adjusting the installation position of the jackhammer connecting plate 22 in the elongated hole 24, the radial position of the pneumatic jackhammer 25 can be adjusted to change its knotting trajectory, so that it can match the ramming requirements at different locations.

[0031] During actual application, dry vibrating material of the furnace lining is added in batches into the furnace for knotting. Usually, the height of the first layer of paving at the bottom is about 40 to 60 mm. A pneumatic pick 25 is used to drive the ramming part 3 to perform ramming and punching. At the same time, the sliding part 21 drives the pneumatic pick 25 to ram evenly along the annular guide rail according to the trajectory of the induction coil. The pneumatic pick 25 uses compressed air as a power source, and the air pressure is set to 0.6 to 1.5 MPa, which can be adjusted according to actual conditions. The overlapping area of two adjacent ramming tracks is set to 20 to 30%. The sliding part 21 moves in the forward direction and then moves in the reverse direction after each circle, ramming in both directions, and ramming for 2 to 4 circles per track. Later, 30 to 40 mm of dry vibrating material is added to each layer, and the ramming step is repeated to tie a knot.

[0032] In this embodiment, the ramming part 3 includes a rod 31 and a flat hammer 32 fixedly connected to the end of the rod 31. The rod 31 is detachably connected to the bottom end of the pneumatic jackhammer 25. The connection structure can be threaded, clamped, etc. The hammer head diameter of the flat hammer 32 is set according to the distance between the outer wall of the crucible and the inner wall of the furnace. Figure 1 and Figure 3 In order to strengthen the connection between the layers of vibrating materials and prevent stratification during the ramming process, the ramming part 3 further includes a ramming fork 33 fixedly connected to one side of the flat hammer 32. The ramming fork 33 is fixedly connected to one side of the flat hammer 32 through an adapter plate 34. Figure 3The vibrating forks 33 are constructed as a series of fork-shaped protrusions fixedly attached to a mounting plate. They are slightly raised above the surface of the flat hammer 32, and are used to roughen the surface of the dry vibrating material being pressed by the flat hammer 32, thereby strengthening the connection between the layers of vibrating material. To ensure the connection strength between the vibrating forks 33 and the flat hammer 32, the ends of the adapter plate 34 are welded to the flat hammer 32 and the mounting plate, respectively.

[0033] In a preferred embodiment, in order to ensure the connection strength between each layer of vibrating material without affecting the compaction effect, the height of the vibrating fork 33 above the surface of the flat hammer 32 should be set to 1 / 3-1 / 4 of the feeding height. Setting it too low will affect the connection strength, and setting it too high will affect the compaction effect.

[0034] In another preferred embodiment, the height of the ramming part 3 is adjustable to adapt to the changing feeding height and further ensure the ramming effect, which can be achieved through the following two embodiments:

[0035] In one embodiment, the height of the legs 11 of the support portion 1 is adjustable, and each leg 11 can be an existing telescopic rod, or a Figure 4 As shown, a sleeve rod structure capable of relative movement is adopted, and the relative positions of the two rods are fixed by a fastener 111.

[0036] In another embodiment, the rod portion 31 of the ramming portion 3 is height-adjustable. In this embodiment, the rod portion 31 is provided with a plurality of detachable rods 311 on one side connected to the pneumatic jackhammer 25. The detachable rods can be connected by a threaded or clip-on connection structure. Different height settings of the rod portion 31 can be achieved by combining different numbers of detachable rods 311.

[0037] The material tamping device for furnace construction provided by the present embodiment can realize semi-automatic knotting operation, with less manual participation and low labor intensity, stable ramming, and can effectively improve the ramming quality, with a high safety factor. At the same time, it can also reduce the influence of the experience factor of manual knotting, and the knotted crucible quality is relatively stable. On the other hand, the present embodiment can adapt to the constantly changing feeding height through the height-adjustable support portion 1 or the ramming portion 3, further ensuring the ramming effect. And by the ramming fork 33 provided in the ramming portion 3, the surface of the dry vibration material punched by the flat hammer 32 can be forked, strengthening the connection between each layer of vibration material, and preventing stratification during the ramming process.
