Description
Technical Field
The utility model relates to the technical field of converter steelmaking, in particular to a secondary muzzle sealing device.
Background
The smoke hood above the converter is provided with a secondary muzzle for inserting a secondary gun, a sealing cap is arranged above the secondary muzzle and can move to open and close the secondary muzzle, and a nitrogen sealing device is arranged between the sealing cap and the secondary muzzle. When the sublance is to be inserted, the sealing cap is moved aside to expose the sublance port, and the nitrogen sealing device blows out nitrogen to prevent smoke dust from overflowing from the sublance port. The patent application number 201310237408.6 discloses a converter vice muzzle sealing device, is provided with a gap between its upper inner tube and the lower inner tube, and nitrogen gas is spouted from this gap to prevent the smoke and dust that produces in the converter to spill over, in the in-service use, because the gap only has one, still have some smoke and dust to spill over from vice muzzle and sealing device, the effect of suppressing dust remains to improve.
Disclosure of Invention
The utility model aims to solve the technical problems and provides a secondary muzzle sealing device aiming at the technical defects.
In order to solve the technical problems, the utility model adopts the following technical scheme: the utility model provides a vice muzzle sealing device, includes roof and bottom plate and the middle part of both is provided with coaxial hole, be provided with between roof and the bottom plate with the coaxial outer tube of hole, one side of outer tube is provided with the intake pipe, the hole department of roof is provided with the inner tube, the hole department of bottom plate is provided with down the inner tube, be provided with on the inner wall of outer tube rather than coaxial annular plate, be provided with a plurality of through-holes that run through its upper and lower surface on the annular plate, the inboard of annular plate is connected with rather than coaxial well inner tube, the internal diameter of well inner tube, upper inner tube and lower inner tube is the same, well inner tube has formed the gap that can blow to the oblique below respectively with between upper inner tube and the lower inner tube.
According to the technical scheme, the bottom surface of the upper inner tube is inclined downwards in the direction from outside to inside, the top surface of the middle inner tube is inclined downwards in the direction from outside to inside, and the inclination angle of the top surface of the middle inner tube is larger than that of the bottom surface of the upper inner tube.
According to the technical scheme, the bottom surface of the middle inner tube is inclined downwards in the direction from outside to inside, the top surface of the lower inner tube is inclined downwards in the direction from outside to inside, and the inclination angle of the top surface of the lower inner tube is larger than that of the bottom surface of the middle inner tube.
Compared with the prior art, the utility model has the following advantages: 1. two gaps are arranged, so that the effect of inhibiting the smoke dust from overflowing from the sealing device is better; 2. the inclination angle of the bottom surface of the gap is larger than that of the top surface of the gap, so that the whole downward airflow which is more close to the whole auxiliary muzzle can be formed, and the smoke dust is less prone to overflowing.
Drawings
Fig. 1 is a schematic structural view of a secondary muzzle seal device.
In the figure: 1. an air inlet pipe; 2. an annular plate; 3. a slit; 4. an upper inner tube; 5. a top plate; 6. an outer tube; 7. a middle inner tube; 8. a lower inner tube; 9. a bottom plate.
Detailed Description
The objects, technical solutions and advantages of the present utility model will become more apparent by the following detailed description of the present utility model with reference to the accompanying drawings. It should be understood that the description is only illustrative and is not intended to limit the scope of the utility model. In addition, in the following description, descriptions of well-known structures and techniques are omitted so as not to unnecessarily obscure the present utility model.
The specific embodiment is as follows: in combination with the illustration of fig. 1, a vice muzzle sealing device, including roof 5 and bottom plate 9 and the middle part of both is provided with coaxial hole, be provided with between roof 5 and the bottom plate 9 with the coaxial outer tube 6 of hole, one side of outer tube 6 is provided with intake pipe 1, the hole department of roof 5 is provided with inner tube 4, the hole department of bottom plate 9 is provided with down inner tube 8, be provided with on the inner wall of outer tube 6 rather than coaxial annular plate 2, be provided with a plurality of through-holes that run through its upper and lower surface on the annular plate 2, the inboard of annular plate 2 is connected with rather than coaxial well inner tube 7, the internal diameter of well inner tube 7, upper inner tube 4 and lower inner tube 8 is the same, well inner tube 7 has formed the gap 3 that can blow to the oblique below with between upper inner tube 4 and the lower inner tube 8 respectively. Part of the nitrogen gas blown from the air inlet pipe 1 is directly sprayed out of the gap 3 below, so that the smoke dust can be prevented from overflowing to a great extent, and the other part of the nitrogen gas enters the upper part of the annular plate 2 through the through hole and then is sprayed out of the gap 3 above, so that the smoke dust can be further prevented from overflowing.
Preferably, the bottom surface of the upper inner tube 4 is inclined downwards in the direction from outside to inside, the top surface of the middle inner tube 7 is inclined downwards in the direction from outside to inside, and the inclination angle of the top surface of the middle inner tube 7 is larger than that of the bottom surface of the upper inner tube 4, so that the thickness of the air flow sprayed out from the gap 3 between the two is rapidly increased along with the increasing distance from the inner wall of the inner tube (the inner tube is formed by the middle inner tube 7, the upper inner tube 4 and the lower inner tube 8), and the air flow which is more close to the whole flow direction and downwards and is distributed over the whole auxiliary muzzle can be formed, and accordingly, the smoke dust is not easy to overflow.
Preferably, the bottom surface of the inner tube 7 is inclined downwards in the direction from outside to inside, the top surface of the lower inner tube 8 is inclined downwards in the direction from outside to inside, and the inclination angle of the top surface of the lower inner tube 8 is larger than that of the bottom surface of the inner tube 7, so that the thickness of the air flow sprayed from the gap 3 between the two is rapidly increased along with the distance from the inner wall of the inner tube, and the air flow which is more close to the whole secondary muzzle and flows downwards can be formed, and the smoke dust is not easy to overflow.
The above-described embodiments are merely illustrative of or explanation for the principles of the present utility model, and the scope of the utility model is not limited thereto. Equivalent substitutions and modifications will occur to those skilled in the art based on the present utility model, and these are intended to be within the scope of the present utility model.
