Description

Technical Field

[0001] The utility model relates to the technical field of crucible cleaning, in particular to cleaning equipment for ingot crucibles. Background Art

[0002] The electron beam melting furnace is the application of high-energy beam technology in metal smelting. Its main working principle is that the cathode block of the electron gun is heated and emitted electrons are accelerated by a high-voltage electrostatic field to form a high-energy electron beam. The electron beam bombards the metal to be smelted after focusing, deflecting and scanning, so that the high-melting-point metal melts. During the smelting process, the ingot pulling rod is connected to the ingot starter and extends into the ingot crucible to form a movable inner bottom of the ingot crucible, forming a molten pool in the crucible. During the smelting operation, the metal solution solidifies and condenses with the ingot starter. The ingot pulling rod can maintain both lifting and lowering and its own rotation, and continuously pulls the ingot out of the ingot crucible. Then the ingot in the crucible becomes longer and longer, and finally the ingot melting is completed.

[0003] After the ingot crucible is completed for smelting materials, it needs to be cleaned to avoid material residue. Existing cleaning equipment can often only clean the inner surface or the outer surface of the ingot crucible, and it is difficult to switch the inner and outer surfaces. As a result, in the process of cleaning the inner and outer surfaces of the ingot crucible, two sets of cleaning structures need to be replaced, which not only makes the cleaning equipment complicated, but also prolongs the cleaning time. Moreover, in the specific cleaning process, it is often only possible to clean the inner and outer surfaces of the ingot crucible of a fixed size, which lacks universality.

[0004] Therefore, it is necessary to invent a cleaning device for ingot crucible to solve the above problems. Utility Model Content

[0022] The utility model is further described below in conjunction with the accompanying drawings. The following embodiments are only used to more clearly illustrate the technical solution of the utility model, and cannot be used to limit the protection scope of the utility model.

[0023] The utility model provides Figure 1-4 The cleaning device for an ingot crucible shown in the figure comprises a cross bracket 1 in a fixed position, a screw rod 6 rotatably arranged below the cross bracket 1, and an extension column 7 extending from the bottom end of the screw rod 6, the screw rod 6 is longitudinally slidably sleeved with a slip ring 12 capable of locking the sliding distance, a plurality of inclined rods 15 are rotatably connected to the side wall of the slip ring 12, a plurality of elastic telescopic components capable of lateral movement are connected to the side wall of the extension column 7, the other end of the inclined rod 15 is rotatably connected to the side wall of the elastic telescopic component away from the extension column 7, and the elastic telescopic components are rotatably connected to the side wall of the elastic telescopic component at one end thereof. An extension rod 17 is formed by extending from one end face of the component away from the extension column 7. The extension rod 17 is rotatably provided with a rotating part that can perform a single 180-degree turn. A brush plate 26 is detachably installed on the bottom end of the rotating part. The brush plate 26 can abut against the inner side wall or the outer side wall of the ingot crucible and slide along the surface. The rotating part drives the brush plate 26 to perform a single rotation of 180 degrees on the extension rod 17, driving the brush plate 26 to rotate 180 degrees, thereby completing the switching of the brush 26 plate facing the inner surface of the ingot crucible and facing the outer surface of the ingot crucible.

[0024] The extension column 7 is detachably sleeved with a collar 8, and the elastic telescopic assembly includes a transverse cylinder 9 connected to the outer peripheral side wall of the collar 8, a movable groove 10 provided in the transverse cylinder 9, and a slide rod 11 that can slide laterally along the movable groove 10. A first spring 24 that can limit the lateral sliding of the slide rod 11 is provided in the movable groove 10. The extension rod 17 is extended to form an end face of the slide rod 11 away from the collar 8. When the slide ring 12 moves up or down along the screw rod 6, the inclined rod 15 pulls the slide rod 11 to slide along the movable groove 10 toward or away from the collar 8, thereby expanding or reducing the spacing between multiple brush plates 26 to adapt to ingot crucibles of different circumferential sizes.

[0025] The parts of the screw rod 6 located above and below the slip ring 12 are both threadedly sleeved with nuts 16 that can lock the position of the slip ring 12, and a plurality of first clamping seats 13 are installed on the side walls of the slip ring 12, and a second clamping seat 14 is installed on the side walls of the end of the slide rod 11 away from the ring 8, one end of the inclined rod 15 is rotatably connected to the first clamping seat 13, and the other end of the inclined rod 15 is rotatably connected to the second clamping seat 14. The first clamping seat 13 and the second clamping seat 14 can facilitate the inclined rod 15 to change its position and angle as the slip ring 12 slides, and at the same time facilitate the inclined rod 15 to drive the slide rod 11 to slide horizontally.

[0026] A sliding hole 19 is provided in the middle of the extension rod 17 and runs through the longitudinal direction. The rotating member includes a hexagonal vertical rod 20 that can slide longitudinally along the sliding hole 19, a chassis 21 provided at the bottom end of the hexagonal vertical rod 20, and a U-shaped bracket 22 provided at the top end of the hexagonal vertical rod 20. Slots 23 for the two ends of the U-shaped bracket 22 to be inserted into are provided at symmetrical positions at the top end of the extension rod 17. A rotating seat 18 is slidably penetrated in the part of the hexagonal vertical rod 20 located below the extension rod 17. A brush plate 26 is detachably installed at the bottom end of the rotating seat 18, and a second spring 25 is sleeved on the part of the hexagonal vertical rod 20 located between the rotating seat 18 and the chassis 21. The size of the sliding hole 19 is larger than the cross-sectional size of the hexagonal vertical rod 20. Therefore, the hexagonal vertical rod 20 can rotate in the sliding hole 19, while the rotating seat 18 can only slide longitudinally between the hexagonal vertical rod 20, but cannot rotate, so that the rotating seat 18 and the brush plate 26 are driven to rotate by the rotation of the hexagonal vertical rod 20.

[0027] When the U-shaped bracket 22 moves up and leaves the slot 23, the hexagonal vertical rod 20 can drive the swivel seat 18 to rotate, and the second spring 25 is compressed during the process; when the hexagonal vertical rod 20 rotates 180 degrees and is released, the U-shaped bracket 22 is inserted into the slot 23 again, and at this time, the brush plate 26 completes a 180-degree turn.

[0028] A driving member 2 is detachably mounted on the top of the cross bracket 1, and a rotating shaft 3 rotatably penetrating the middle of the cross bracket 1 is mounted on the output end of the driving member 2. A chuck 4 is provided on the portion of the rotating shaft 3 located below the cross bracket 1, and the top of the screw 6 is connected to the bottom of the chuck 4. The driving member 2 drives the rotating shaft 3 to rotate, thereby driving multiple brush plates 26 to rotate along the inner surface or outer surface of the ingot crucible, thereby reciprocatingly brushing the inner surface or outer surface of the ingot crucible.

[0029] The four side ends of the cross bracket 1 are longitudinally plugged with water supply pipes 5 that can spray water to the brush plate 26. The water supply pipes 5 can supply water to the brush plate 26 to facilitate the combination of flushing and brushing.

[0030] In the utility model, by changing the longitudinal position of the slip ring 12 on the screw 6, the elastic telescopic assembly is pulled horizontally by multiple inclined rods 15 to change the sliding distance, that is, the horizontal position of the extension rod 17, the rotating member and the brush plate 26 is changed. Since one end of the multiple inclined rods 15 is synchronously moved with the slip ring 12, that is, the multiple brush plates 26 are synchronously moved close to or away from the sliding, which is suitable for ingot crucibles with different circumferential sizes, and the rotating member can drive the brush plate on the extension rod 17 to perform a single rotation of 180 degrees, that is, the brush plate 26 can be 1 The brush plate 26 can be rotated 80 degrees to switch between facing the inner surface of the ingot crucible and facing the outer surface of the ingot crucible. Finally, when facing ingot crucibles of different circumferential sizes, the brush plate 26 can be driven by the rotating part to rotate 180 degrees, so that the brush plate 26 can complete the switching of facing the inner and outer surfaces, thereby realizing the brush plate 26 to complete the brushing operation of the inner or outer surface of the ingot crucibles of different circumferential sizes. The specific switching only needs to change the position of the slip ring 12 and the 180-degree rotation of the rotating part, which is convenient and fast, and has sufficient universality.

[0031] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the technical principles of the present invention. These improvements and modifications should also be regarded as the protection scope of the present invention.
