Description

Technical Field

[0001] The utility model relates to the technical field of metallurgical equipment, in particular to a ladle drainage sand discharge device. Background Art

[0002] At present, the drainage sand used for ladles of most large-scale steel production enterprises is usually mainly chromium ore. The chromium ore ladle drainage sand is mainly composed of chromite and quartz phases. The quartz phase contains more impurities such as Al2O3, K2O and CaO, and some chromite contains impurities such as magnesium silicate.

[0003] When discharging drainage sand, existing discharge equipment usually discharges the drainage sand directly from the bottom of the conical sleeve to the outside, which will produce a collapse effect during the discharge process, causing the drainage sand to flow around and fail to be well drained to a specific area. Utility Model Content

[0005] A ladle sand discharge device comprises a base, a fixed column is installed on the top of the base, a constraint ring is slidably connected to the outer surface of the fixed column, a conical barrel is provided on the outside of the fixed column, the top of the fixed column extends to the interior of the conical barrel, an inner wall of the constraint ring is provided with an oblique opening near the bottom edge, an annular groove is provided on the inner wall of the constraint ring near the top edge of the oblique opening, a rubber ring is clamped between the inner walls of the annular groove, and one side of the rubber ring is in contact with the outer surface of the fixed column.

[0006] Optionally, guide grooves are provided on the outer surfaces of both sides of the fixed column, and a conical guide ring is slidably connected to the outer surface of the fixed column, and the inner wall of the conical guide ring is in contact with the outer surface of the fixed column.

[0007] Optionally, drainage grooves are provided on the top of the conical guide ring near the edges on both sides, and the two drainage grooves are located directly below the guide groove.

[0008] Optionally, a fixing rod is provided between the outer surfaces of both sides of the conical barrel near the top edge, and the outer surfaces of the fixing rod are threadedly connected with locking nuts near the edges of both ends.

[0009] Optionally, one end of the two locking nuts is correspondingly fitted with the outer surface of the conical barrel, and a docking sleeve is fixed to the bottom of the base.

[0010] Optionally, a transmission cavity is provided inside the fixed column, a plurality of side openings are provided on the inner wall of the transmission cavity at equal intervals along the circumferential direction, and a cross slide is slidably connected between the inner walls of the transmission cavity.

[0011] Optionally, the four ends of the cross slide slide correspondingly inside the side opening, the four ends of the cross slide are correspondingly fixed on the inner wall of the conical guide ring, a spring is fixed on the bottom of the cross slide, and the bottom of the spring is fixed on the inner bottom surface of the transmission cavity.

[0012] After adopting the above technical solution, the present invention has the following beneficial effects compared with the prior art. Of course, any product implementing the present invention does not necessarily need to achieve all of the advantages described below at the same time:

[0013] 1. In the present invention, when discharging the material inside the conical barrel to the outside, it is necessary to use an external lifting device to pull the conical barrel upward along the fixed column. When the restraint ring slides over the bottom of the guide groove, the material inside the conical barrel can flow through the guide groove to the inside of the guide groove on the conical guide ring, thereby guiding the material. When the restraint ring slides upward, the cross slide plate together with the conical guide ring can be lifted upward by the elastic force of the spring.

[0014] 2. In the present invention, when closing the guide groove, it is only necessary to slide the conical barrel downward along the fixed column. During the sliding process, the inclined surface at the bottom of the limit ring first contacts the bottom outlet of the guide groove, reducing the outflow of material. Then, when the rubber ring slides below the bottom outlet of the guide groove, the guide groove can be closed. While closing the guide groove, the conical guide ring will be pressed downward to reset the conical guide ring. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0023] The present invention will now be described in further detail with reference to the accompanying drawings.

[0024] Example 1, as Figure 1-4 As shown, the utility model provides a technical solution for a ladle sand discharge device: it includes a base 1, a fixed column 6 is installed on the top of the base 1, and a constraint ring 12 is slidably connected to the outer surface of the fixed column 6. A conical barrel 4 is provided on the outside of the fixed column 6, and the top of the fixed column 6 extends to the inside of the conical barrel 4. An oblique opening 15 is provided on the inner wall of the constraint ring 12 near the bottom edge, and an annular groove 13 is provided on the inner wall of the constraint ring 12 near the top edge of the oblique opening 15. A rubber ring 14 is clamped between the inner walls of the annular groove 13, and one side of the rubber ring 14 is in contact with the outer surface of the fixed column 6.

[0025] The effect achieved by the entire embodiment 1 is that when discharging the material inside the conical barrel 4 to the outside, it is necessary to use external lifting equipment to pull the conical barrel 4 upward along the fixed column 6. When the constraint ring 12 slides over the bottom of the guide groove 7, the material inside the conical barrel 4 can flow through the guide groove 7 to the inside of the guide groove 3 on the conical guide ring 2, thereby guiding the material. When the constraint ring 12 slides upward, the cross slide 11 together with the conical guide ring 11 can be lifted upward under the action of the elastic force of the spring 10.

[0026] Example 2, as Figure 1-4As shown, guide grooves 7 are provided on the outer surfaces of both sides of the fixed column 6, and the outer surface of the fixed column 6 is slidably connected with a conical guide ring 2. The inner wall of the conical guide ring 2 fits with the outer surface of the fixed column 6. A guide groove 3 is provided on the top of the conical guide ring 2 near the edges on both sides. The two guide grooves 3 are located directly below the guide groove 7. A fixing rod 5 is provided between the outer surfaces of both sides of the conical barrel 4 near the top edge. The outer surface of the fixing rod 5 is threadedly connected with a locking nut 8 near the edges of both ends. One end of the two locking nuts 8 is screwed to the It should fit together with the outer surface of the conical barrel 4. A docking sleeve 16 is fixed to the bottom of the base 1. A transmission cavity 9 is opened inside the fixed column 6. The inner wall of the transmission cavity 9 is opened with multiple side openings 17 at equal intervals along the circumferential direction. A cross slide 11 is slidably connected between the inner walls of the transmission cavity 9. The four ends of the cross slide 11 slide correspondingly inside the side opening 17. The four ends of the cross slide 11 are correspondingly fixed on the inner wall of the conical guide ring 2. A spring 10 is fixed to the bottom of the cross slide 11, and the bottom of the spring 10 is fixed to the inner bottom surface of the transmission cavity 9.

[0027] The effect achieved by the entire embodiment 2 is that when closing the guide groove 7, it is only necessary to slide the conical barrel 4 downward along the fixed column 6. During the sliding process, the inclined surface 15 at the bottom of the limiting ring 12 first contacts the bottom outlet of the guide groove 7, so that the outflow of material is reduced. Then, when the rubber ring 14 slides below the bottom outlet of the guide groove 7, the guide groove 7 can be closed. At the same time as the guide groove 7 is closed, the conical guide ring 2 will be pressed downward to reset the conical guide ring 2.

[0028] Working principle: When using this device, when discharging the material inside the conical barrel 4 to the outside, it is necessary to use an external lifting equipment to pull the conical barrel 4 upward along the fixed column 6. When the constraint ring 12 slides over the bottom of the guide groove 7, the material inside the conical barrel 4 can flow through the guide groove 7 to the inside of the guide groove 3 on the conical guide ring 2, thereby guiding the material. When the constraint ring 12 slides upward, the cross slide 11 together with the conical guide ring 11 can be lifted upward under the elastic force of the spring 10. When closing the guide groove 7, it is only necessary to slide the conical barrel 4 downward along the fixed column 6. During the sliding process, the inclined surface 15 at the bottom of the limit ring 12 first contacts the bottom outlet of the guide groove 7, reducing the outflowing material. Then, when the rubber ring 14 slides below the bottom outlet of the guide groove 7, the guide groove 7 can be closed. While closing the guide groove 7, the conical guide ring 2 will be pressed downward to reset the conical guide ring 2.
