the liquid outlet end of the water tank is connected with the liquid inlet end of the hot blast valve through a water supply device, and the liquid outlet end of the hot blast valve is communicated with the water tank through a water return pipe.
Preferably, the water supply device comprises a water supply centrifugal pump connected with the water tank, the water outlet end of the water supply centrifugal pump is connected with a water supply assembly, and the water supply assembly is connected with three water inlets of the hot blast valve through three water supply pipes.
Preferably, the number of the feed water centrifugal pumps is not less than 2.
Advantageous effects
The utility model provides a swift cooling device of interim hot-blast valve. The method has the following beneficial effects: this swift cooling device of interim hot-blast valve installs the hot-blast valve additional between combustor and hot-blast furnace overhaul manhole, cuts off the laggard cooling of going on for the hot-blast valve, can avoid high temperature to cause the scald for the operation personnel during the dismouting. And avoids frequently disassembling the burner like a conventional oven dryer; the device is simple to use, reduces the labor intensity and particularly plays a role in cutting off high temperature in the furnace.
Drawings
Fig. 1 is a schematic structural diagram of the present invention.
In the figure: 1. the hot blast stove comprises a water inlet pipe, a water tank, a water return pipe, a water supply centrifugal pump, a water supply assembly, a water supply pipe, a furnace drier, 8 large and small head connecting pipes A and 9, a hot blast valve, 10 large and small head connecting pipes B and 11 and a hot blast stove maintenance manhole.
Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.
The following working principles, detailed connecting means thereof, and following main descriptions of the working principles and processes shall be referred to by those skilled in the art to connect the components in this case in sequence, and the specific connecting and operating sequence shall be described below.
As can be seen from fig. 1, the temporary hot blast valve rapid cooling device comprises a hot blast stove inspection manhole 11, a water tank 2 and a stove drying device arranged on the hot blast stove inspection manhole 11, wherein a water inlet pipe 1 is arranged on the water tank 2;
the water inlet pipe 1 is a water replenishing pipe.
The baker device includes hot-blast valve 9, and big reducer connecting pipe B10 and hot-blast furnace overhaul manhole 11 flange seal connection are passed through to the one end of hot-blast valve 9, and the other end of hot-blast valve 9 is connected with the baker through big reducer connecting pipe A8.
In the specific implementation process, it is worth pointing out that, during installation, the hot blast valve 9 body is firstly fixedly connected to the hot blast stove inspection manhole 11 through the reducer connecting pipe B10: the other end of the hot blast valve 9 is fixed with a reducer connecting pipe A8 for the oven dryer;
the liquid outlet end of the water tank 2 is connected with the liquid inlet end of the hot blast valve 9 through a water supply device, and the liquid outlet end of the hot blast valve 9 is communicated with the water tank 2 through the water return pipe 3.
The number of the liquid outlet pipes of the water tank 2 is 1, water flow is supplied to an inlet pipeline at the lower part of the water supply centrifugal pump 4 from the water tank 2 and then is divided into two water supply centrifugal pumps 4, the two centrifugal pumps can be operated separately, and an outlet pipeline at the upper part of the water supply centrifugal pump 4 is supplied to the water supply assembly 5.
The water supply device comprises water supply centrifugal pumps 4 connected with the water tank 2, the number of the water supply centrifugal pumps 4 is not less than 2, the water outlet ends of the water supply centrifugal pumps 4 are connected with water supply assemblies 5, and the water supply assemblies 5 are connected with three water inlets of a hot blast valve 9 through three water supply pipes 6.
