Description

Automatic water supply device for preventing air port from water cut-off after air port water inlet hose falls off

Technical Field

The utility model relates to an ironmaking equipment field, in particular to prevent that wind gap water supply installation of wind gap water supply interruption after hose that intakes in the wind gap drops.

Background

The blast furnace tuyere extends into a blast furnace hearth, faces a complex environment with high temperature and high pressure in the furnace, the heat load of a working surface is large, the normal work can be ensured only by adopting forced cooling, industrial water cooling is generally adopted during normal production, a water path in the tuyere is connected with an external water supply system through a water inlet pipe, a water outlet pipe, a water inlet branch pipe, a water inlet hose, a tuyere water inlet pipe and a tuyere water inlet pipe which are about 7m higher than the plane of the tuyere, the industrial water is uniformly discharged into a pipe network through a tuyere water outlet pipe, a water outlet hose, a water outlet branch pipe and a tuyere water tank, the water inlet branch pipe, the tuyere water inlet pipe and the water inlet hose are connected through bayonet connectors, the connection modes of the tuyere water outlet pipe, the tuyere water outlet pipe and the water outlet hose are also connected through bayonet connectors, the bayonet connection modes can not ensure 100% safety, particularly under the industrial production state, an operator probably forgets to fasten the buckle by using an iron wire, or the buckle is loosened due to pipeline vibration, so that the water supply of the air port falls off due to the fact that the hose falls off, if the water outlet hose falls off, the water inlet pipe of the air port can still normally supply water, the air port is not cooled, only the water outlet of the air port can be directly discharged to the air port platform to cause waste, but the normal production can be ensured; if the water inlet hose falls off, because the heat load of the working surface of the tuyere is extremely large, once the water supply of the tuyere falls off, the residual water of the tuyere is heated and evaporated by the huge heat load in an extreme time, and an extremely strong steam jet flow is formed outside a pipeline, so that field personnel can hardly approach the tuyere for maintenance, and the tuyere can be burnt through within 5min, thereby causing serious and serious accidents.

At present, in the iron-making industry, once a tuyere water inlet hose falls off, the water supply of the tuyere is cut off, and blast furnace operators can only immediately and greatly reduce the wind until the blast furnace operators stop the wind, so that serious accidents are avoided.

Disclosure of Invention

The utility model aims to solve the technical problem that an automatic water supply installation that prevents that wind gap intake hose from droing back wind gap outage keeps wind gap industrial water to supply in succession, for the production is salvageed and is created the condition, avoids the emergence of malignant accident because of wind gap intake hose drops and causes.

In order to achieve the above object, the utility model adopts the following technical scheme:

the utility model provides a prevent that wind gap from breaking off water automatic water supply installation after wind gap intake hose drops, includes the wind gap, wind gap inlet tube, wind gap outlet pipe, the wind gap inlet tube is through the intake hose, intake branch pipe and delivery pipe connection, the wind gap outlet pipe is through going out the water hose and go out the water branch pipe connection, add the industry water drum between delivery pipe and play water branch pipe, the delivery pipe is connected to the water inlet of industry water drum, reserve inlet tube is connected to the delivery port of industry water drum, reserve inlet tube passes through electronic tee bend ball valve and goes out the water branch pipe connection, be equipped with the flowmeter on the play water branch pipe between electronic tee bend ball valve and play water hose.

The electric three-way ball valve and the flowmeter are respectively electrically connected with the controller.

The water outlet branch pipe drains water to the air port water tank.

And the tuyere water tank is connected with an industrial water pipe network.

Compared with the prior art, the beneficial effects of the utility model are that:

the utility model discloses after blast furnace tuyere intake hose drops, for the production is salvageed and is created the condition, the emergence of accidents such as the water break that avoids causing because of tuyere intake hose drops or damping down that can be fine reduces blast furnace economic loss.

Drawings

Fig. 1 is a schematic structural diagram of the present invention.

In the figure: the device comprises a tuyere 1, an electric three-way ball valve 2, a water inlet pipe 3, a controller 4, a water outlet branch pipe 5, a water inlet hose 6, a water outlet hose 7, a tuyere water inlet pipe 8, a tuyere water outlet pipe 9, a water inlet branch pipe 10, a water supply pipe 11, an industrial water drum 12, a tuyere water tank 13, an industrial water pipe network 14 and a flowmeter 15.

Detailed Description

The following further describes the embodiments of the present invention with reference to the attached drawings:

referring to fig. 1, an automatic water supply device for preventing water break of a tuyere after a tuyere water inlet hose falls off comprises a tuyere 1, a tuyere water inlet pipe 8 and a tuyere water outlet pipe 9, wherein the tuyere water inlet pipe 8 is connected with a water supply pipe 11 through a water inlet hose 6 and a water inlet branch pipe 10, the tuyere water outlet pipe 9 is connected with a water outlet branch pipe 5 through a water outlet hose 7, an industrial water drum 12 is additionally arranged between the water supply pipe 11 and the water outlet branch pipe 5, a water inlet of the industrial water drum 12 is connected with the water supply pipe 11, a water outlet of the industrial water drum 12 is connected with a standby water inlet pipe 3, the standby water inlet pipe 3 is connected with the water outlet branch pipe 5 through an electric three-way ball valve 2, and a flow meter 15 is arranged on the water outlet branch pipe 5 between the electric three-way ball valve 2 and the water outlet hose 7.
