Description
Technical Field
The utility model relates to a mechanical equipment technical field, especially a novel through-flow tuyere small sleeve inner core.
Background
The blast furnace tuyere is an important device for supplying air to the steelmaking blast furnace, the through-flow tuyere consists of an outer sleeve, a middle sleeve and a small sleeve, and the small sleeve extends into the furnace, works in a high-temperature environment and is easy to damage, so the through-flow tuyere is very important for the circular cooling of the small sleeve. The basic structure of the existing small sleeve comprises a taper sleeve, an inner cavity of the taper sleeve is an air inlet hole, a water cavity is annularly arranged in the cavity wall of the taper sleeve, a water inlet hole and a water outlet hole which are communicated with the water cavity are formed in the end face of the thick end of the upper shell, circulating water is supplied to the water cavity to cool the air inlet small sleeve, most of cold water can flow out of the water outlet hole after entering the water cavity from the water inlet hole, and therefore water circulation of the water cavity close to the thin end section of the taper sleeve is not smooth, and the cooling effect of the small sleeve is poor.
SUMMERY OF THE UTILITY MODEL
In order to solve the above problems, the present invention provides a novel inner core of a through-flow tuyere small sleeve, which is installed in a water cavity to prolong the water flow path of cooling water.
The embodiment of the utility model provides an in adopt following scheme to realize: the utility model provides a novel through-flow tuyere small sleeve inner core, which comprises a body, the body is hollow round platform shape structure, follow supreme coiling down on the outer wall of body and be provided with the water conservancy diversion piece, be provided with first retaining ring in the top periphery of body, the notch of intaking has been seted up on the first retaining ring, be provided with the second retaining ring in the periphery of body bottom, the notch of intaking has been seted up on the second retaining ring.
In an embodiment of the present invention, the top of the flow deflector is connected to one side edge of the water inlet notch; the bottom of the flow deflector is connected with one side edge in the water outlet notch.
The utility model relates to an embodiment, the thickness h of water conservancy diversion piece =5.0mm, the width w of water conservancy diversion piece =15 mm.
The utility model has the advantages that: the utility model provides a novel through-flow tuyere small sleeve inner core forms the rivers route of coiling formula, increases the dwell time of cooling water in this inner core, and the cooling effect of at utmost utilization water reduces the use amount of the energy, reduces refrigerated cost, realizes abundant cooling, increases life.

Detailed Description
The present invention will be further explained with reference to the accompanying drawings.
Referring to fig. 1, the utility model provides a novel through-flow tuyere small sleeve inner core, including body 11, body 11 is hollow round platform shape structure, it is provided with water conservancy diversion piece 12 to coil from supreme down on the outer wall of body 11, be provided with first retaining ring 13 in the top periphery of body 11, water inlet notch 15 has been seted up on first retaining ring 13, be provided with second retaining ring 14 in the periphery of body bottom, water outlet notch 16 has been seted up on second retaining ring 14, forms the rivers route of coiling, increases the residence time of cooling water, and the cooling effect of the at utmost utilization water realizes abundant cooling.
Referring to fig. 1, in an embodiment of the present invention, the top of the flow deflector 12 is connected to a side edge of the water inlet notch 15; the bottom of the deflector 12 is connected with one side edge in the water outlet notch 16; so as to form an unblocked cooling water flow passage.
Referring to fig. 1, in an embodiment of the present invention, the thickness h =5.0mm of the baffle 12, and the width w =15mm of the baffle 12, so as to save manufacturing raw materials as much as possible while ensuring the structural strength.
The utility model discloses the theory of operation below has:
when in use, the inner barrel 3 is sleeved in the lower shell 2, the inner core 1 is arranged between the lower shell 2 and the inner barrel 3, and the upper shell 4 is arranged; after being assembled, the pressure gas is installed at the air inlet end of an air supply and oxygen supply pipeline of an iron-making or steel-making furnace, and the pressure gas supplied by the air supply pipeline enters the furnace body through the through-flow tuyere for combustion supporting and the like. Cooling is introduced from the water inlet of the upper shell, enters the coiled flow guide cavity formed between the inner core 1 and the lower shell 2 through the water inlet notch 15, and flows along the cavity. After the cooling water is spirally circulated (see the arrow in the figure for indication), the cooling water flows to a backflow cavity formed between the inner core 1 and the inner barrel 3 through the water outlet notch 16 and finally flows out from the water outlet 42 on the upper shell 4. And fully cooling the through-flow tuyere so as to prevent high-temperature gas in the blast furnace from burning out the through-flow tuyere.
The above description is only for the preferred embodiment of the present invention, and should not be interpreted as limiting the scope of the present invention, which is intended to cover all the equivalent changes and modifications made in accordance with the claims of the present invention.
