The technical field is as follows:
the utility model belongs to the technical field of float glass production technique and specifically relates to an automatic fire extinguishing device for a melting furnace or a tin bath electric heating control room.
Background art:
in the production process of float glass, there are two heating modes for melting glass, namely a flame heating method and an electric heating method. The special glass and high-grade electronic grade glass raw wires mostly adopt an electrically heated melting furnace and an electrically heated tin bath, and have the advantages of improving the temperature of deep molten glass, improving the thermal uniformity of the molten glass and being beneficial to the homogenization of the molten glass; the melting rate, the yield and the thermal efficiency are higher than those of a flame kiln which uses a single flame, the glass quality can be greatly improved, and the defects are that the electric heating power is high, the current is high, and certain potential safety hazards exist in electric heating.
And the electric wires and cables work for a long time under the state of large current, and the cables are easy to overheat to cause fire accidents. A large number of control cabinets arranged in rows are arranged in a melting furnace and a tin bath central control room, wires and cables in the cabinets are criss-cross, contacts are various, heat dissipation conditions are poor, and potential safety hazards are large. Once a fire disaster occurs, the difficulty of fighting is high, and great loss is brought to enterprises.
The utility model has the following contents:
the utility model provides an automatic fire extinguishing device for a melting furnace or a tin bath electric heating control room, which aims to overcome the defects in the prior art.
The application provides the following technical scheme:
the utility model provides a melting furnace or molten tin bath electrical heating control room automatic fire extinguishing device which characterized in that: the fire extinguishing agent storage tank is communicated with a gas pressure tank on one side, and the outlet ends of the fire extinguishing agent storage tank and the gas pressure tank are respectively provided with a solenoid valve which is correspondingly matched with each other; the outlet end of the fire extinguishing agent storage tank is communicated with a main pipeline, one end of the main pipeline is connected in parallel with a group of branch pipes distributed in the electric heating control chamber, and a group of spray heads are uniformly distributed on each branch pipe; the electric heating control room is internally provided with a group of smoke inductors and a group of temperature inductors, and the electromagnetic valve, the smoke inductors, the temperature inductors and the spray head are matched with the control module in an electric signal connection mode.
On the basis of the technical scheme, the following further technical scheme can be implemented:
and a second fire extinguishing agent storage tank is further arranged on one side of the gas pressure tank, a branch pipe communicated with the main pipeline is arranged at the outlet end of the second fire extinguishing agent storage tank, and a second electromagnetic valve which is in electric signal connection and matching with the control module is further arranged at the outlet end of the second fire extinguishing agent storage tank.
Utility model advantage:
the utility model discloses simple structure, convenient to use correspond the conflagration and can in time discover to put out in time, avoid the condition of a fire to stretch, effectual reduction loss.
Description of the drawings:
fig. 1 is a schematic structural diagram of the present invention.
The specific implementation mode is as follows:
as shown in figure 1, the automatic fire extinguishing device for the melting furnace or tin bath electric heating control room comprises a fire extinguishing agent storage tank 1 and a second fire extinguishing agent storage tank 11, wherein the fire extinguishing agent storage tank 1 and the second fire extinguishing agent storage tank 11 are steel cylinders, the pressure resistance is 6.5MPa, fire extinguishing agent perfluorohexanone is stored inside the fire extinguishing agent storage tank, the perfluorohexanone is of a chemical structure consisting of carbon atoms, fluorine atoms and oxygen atoms, and is colorless, tasteless and nontoxic and is in a liquid state at normal temperature.
Still be equipped with gas pressure tank 2 between fire extinguishing agent storage tank 1 and second fire extinguishing agent storage tank 11, 2 liquid level steel cylinders of gas pressure tank, inside stores up high-pressure nitrogen gas. The end parts of the outlet ends of the gas pressure tank 2 and the fire extinguishing agent storage tank 1 are respectively provided with a corresponding matched electromagnetic valve 10, and the end part of the outlet end of the second fire extinguishing agent storage tank 11 is provided with a corresponding matched second electromagnetic valve 11 b.
An air pipe 2a is communicated with the outlet end of the gas pressure tank 2, the air pipe 2a is similar to a T-shaped structure, and the other two ends of the air pipe are respectively communicated with the tank bodies of the fire extinguishing agent storage tank 1 and the second fire extinguishing agent storage tank 11.
The outlet end of the fire extinguishing agent storage tank 1 is communicated with a main pipeline 3, one end of the main pipeline 3 extends into the electric heating control chamber, the main pipeline 3 outside the electric heating control chamber is communicated with a branch pipe 11a, and one end of the branch pipe 11a is communicated with the outlet end of the second fire extinguishing agent storage tank 11.
A group of branch pipes 4 are distributed on a ceiling in an electric heating control chamber of a kiln or a tin bath in parallel, and one ends of the group of branch pipes 4 are communicated with one end of a main pipeline 3 extending into the electric heating control chamber. A group of spray heads 5 which spray downwards are uniformly distributed on each branch pipe 4.
The main pipeline 3 is also provided with a flow detector 3a which is correspondingly matched with the main pipeline.
A group of smoke sensors 8 and a group of temperature sensors 9 distributed in parallel and a ventilator (not shown) are also distributed on the ceiling in the electric heating control room.
A control module 7 is arranged outside the electric heating control chamber, and the control module 7 is in electric signal connection and matching with the electromagnetic valve 10, the second electromagnetic valve 11b, the flow detector 3a, the ventilation fan, the smoke sensor 8 and the temperature sensor 9 through cables. An alarm is also arranged on the control module 7.
The working process is as follows:
when the smoke sensor detects smoke or the temperature sensor senses overhigh temperature, signals are transmitted to the control module, the control module controls the alarm to send out audible and visual alarm to inform workers, the electromagnetic valve and the second electromagnetic valve are opened simultaneously, so that high-pressure nitrogen in the gas pressure tank rushes into the fire extinguishing agent storage tank and the second fire extinguishing agent storage tank to push perfluorohexanone in the two tanks to enter the branch pipe through the main pipeline and then to be sprayed out from the spray head, and fire extinguishing operation is carried out in the electric heating control chamber.
When the flow detector detects that no fire extinguishing agent flows in the main pipeline, a signal is transmitted to the control module, and the control module controls the ventilation fan to start to ventilate the electric heating control room. At this moment, the prompt that the staff can enter can be displayed on the display screen on the control module, so that the staff can enter the electric heating control chamber in time to check the condition.
