Abstract
The utility model discloses a device for sealing a water beam at the bottom of a step heating furnace. The device comprises a flange arranged on an outer pipe, the flange is fixed at the bottom of the outer pipe, and the flange is provided with a flange covered plate for sealing. The flange is selected according to factors such as the outlet pressure of a circulating pump, the water pipe diameter of the outer pipe and the like, so that the aperture of the flange is matched with the inner diameter of the outer pipe. Then, a welding rod is selected according to the materials of a cooling water pipe so as to weld the flange at the bottom of the outer pipe. According to the utility model, scales in a gap between a core pipe and the outer pipe can be removed clearly, so that cooling water can circulate normally, thereby ensuring the normal operation of the heating furnace; and by using the sealing device disclosed by the utility model, a situation that scales generated in a cooling water pipe are difficult to clean due to a cooling water problem can be significantly reduced, thereby saving time and reducing the human consumption.
Description
Technical field
The utility model relates to a kind of walking beam furnace, specifically a kind of step heating-furnace furnace bottom water beam sealing device.
Background technology
Metallurgical Enterprise is used heating furnace, even cooling water is after treatment in the process of using, because furnace high-temperature, cooling water pipe still can fouling in the stove, and its main component is MgO not, CaO.When cooling water quality was relatively poor, amount of scale buildup can increase greatly, stopped up the support post of cooling water beam, and cooling effect reduces greatly.Spherical shell cover is adopted at present general step heating-furnace furnace bottom cooling water pipe sealing; Fig. 1 is the spherical sealing of an existing step rate cooling water pipe sketch map; When the water pipe obstruction occurring than serious situation; Rely on the general chemical treatment mode can not treatment of dirt in the water pipe is clean, at this moment just need open the sealing of furnace bottom cooling water pipe, carry out artificial treatment.Because spherical shell cover 13 front cover apertures are less, generally can only the core pipe of cooling water pipe be handled fully during artificial treatment, but clear up between core pipe and the outer tube less than, can find out that by Fig. 1 during artificial scale removal, the dirt between core pipe 11 and the outer tube 12 can not be removed.After heating furnace used a period of time like this, cooling water pipe still can be because of cooling water stove circulation and breaking entirely, must the blowing out processing, influenced ordinary production.
Summary of the invention
In order to overcome the water pipe blockage problem that exists in the prior art; The purpose of the utility model provides a kind of step heating-furnace furnace bottom water beam sealing device; This device can be handled the fouling of gap between core pipe and the outer tube clean, makes cooling water ability normal circulation, guarantees the normal operation of heating furnace.
The purpose of the utility model realizes through following technical scheme:
A kind of step heating-furnace furnace bottom water beam sealing device, it is characterized in that: this device comprises the flange that is arranged on the outer tube, said flange is fixed on the bottom of outer tube, on flange, is provided with the flange plate that is used for sealing.
In the utility model, according to circulating-pump outlet pressure, factors such as outer tube water pipe diameter are selected flange, and the bore of said flange and the internal diameter of outer tube are suitable.Select welding rod flange to be welded on the bottom of outer tube according to the material of cooling water pipe again.
Select corresponding flange plate according to the flange model, adopt screw nut, spirotallic gasket outer tube to seal.Between flange and flange plate, be provided with sealing gasket.
The utility model is analyzed from existing ball-type sealing foul; Front cover aperture, bottom is less to be the immediate cause that causes dirt cleaning difficulty; The spherical shell cover upper diameter is similar with the cooling water pipe diameter; In order to reduce to clear up difficulty, directly the ball-type sealing is cut away with the cooling water pipe contact position, adopt flange and flange plate to seal.
Compared with prior art, the utility model convenient disassembly can be handled the fouling of gap between core pipe and the outer tube totally, makes cooling water ability normal circulation, guarantees the normal operation of heating furnace.Use through 5 months, can significantly reduce the cleaning difficulty that the cooling water in-tube fouling that caused by the cooling water problem is caused, practiced thrift the time, reduced the manpower consumption.
Description of drawings
Fig. 1 is the spherical sealing of an existing step rate cooling water pipe sketch map.
Fig. 2 is the structural representation of the utility model.
The specific embodiment
The described step heating-furnace furnace bottom of a kind of the utility model water beam sealing device is seen Fig. 2, and this device comprises the flange 3 that is arranged on the outer tube 2, and flange 3 is fixed on the bottom of outer tube 2, on flange 3, is provided with the flange plate 4 that is used for sealing.According to circulating-pump outlet pressure, factors such as outer tube water pipe diameter are selected flange, and the bore of flange and the internal diameter of outer tube are suitable.Select welding rod flange to be welded on the bottom of outer tube according to the material of cooling water pipe again.
Select corresponding flange plate according to the flange model, adopting screw nut, spirotallic gasket outer tube is that cooling water pipe seals.Between flange and flange plate, be provided with sealing gasket 5.Begin pressure testing after the sealing.Do not have the situation of leaking and to drop into practicality.
The utility model was just trying to use 5 months; Convenient disassembly; Can the fouling of gap between core pipe 1 and the outer tube 2 be handled totally, make the cooling water can normal circulation, can significantly reduce the cleaning difficulty that the cooling water in-tube fouling that caused by the cooling water problem is caused; Practice thrift the time, reduced the manpower consumption.
