Description

Technical Field

[0001] The utility model belongs to the technical field of fire protection, and relates to a special fire extinguishing device for textile equipment. Background Art

[0002] At present, a series of new environmentally friendly textile equipment has been developed in China's textile equipment industry, such as opening machines, cotton carding machines, carding machines, etc., for textile production and recycling. The processing raw materials of textile equipment are generally cotton, waste cotton wadding, cotton cloth, cotton yarn, etc. These are all flammable and combustible materials, and once a fire breaks out, it is extremely easy to spread rapidly. The employees of textile equipment generally only equip simple fire fighting equipment such as portable fire extinguishers. Coupled with the very rapid spread of fires in textile raw materials, it is very difficult to take effective fire extinguishing measures.

[0003] There is a Chinese utility model patent with the publication number of CN209221395U, a fire detection tube type fire extinguishing device, including a device to be protected, and further including a fire extinguishing agent storage bottle, a fixed bracket and a fastening belt. The fixed bracket is in an inverted L shape, the fixed bracket is arranged on the side wall of the device to be protected, the fire extinguishing agent storage bottle is arranged on the fixed bracket, the fastening belt is in a semicircular shape, the fastening belt is arranged on the fire extinguishing agent storage bottle, and the fastening belt is fixedly connected to the side wall of the device to be protected; a bottle head control valve is installed at the top of the fire extinguishing agent storage bottle, a first pressure gauge, an electromagnetic driver, a high-pressure explosion-proof tube and a fire detection tube are arranged on the bottle head control valve. The fire detection tube is arranged in a snake shape inside the device to be protected, and the other end of the fire detection tube is provided with a second pressure gauge. The fire detection type fire extinguishing device further includes an audible and visual alarm. The electromagnetic driver is connected to the audible and visual alarm. The bottle head control valve is connected to the high-pressure explosion-proof tube. The high-pressure explosion-proof tube is connected with a nozzle. An O-shaped sealing ring is arranged between the high-pressure explosion-proof tube and the nozzle. The cross-section of the nozzle is a regular hexagon. A plurality of first spray holes are arranged on the side wall of the nozzle. A plurality of second spray holes are arranged on the front surface of the nozzle. A triangular cross-section is arranged at the included angle between the adjacent side walls and the front surface of the nozzle. A third spray hole is arranged on the triangular cross-section.

[0004] The prior art has the following technical defects:

[0005] The above technical solution solves the problem that a fire inside the equipment cannot be detected and extinguished in time when there is no one. However, during the operation of the equipment, if a person discovers a fire inside the equipment but it is not yet sufficient to trigger the fire detection tube, resulting in the inability to extinguish the fire, the person needs to stop the machine to find the fire extinguishing device and then open the equipment to extinguish the fire, with low efficiency and prone to causing the fire situation to become larger. Content of the Utility Model

[0006] The technical problem to be solved by the utility model is: to overcome the deficiencies of the prior art and provide a special fire extinguishing device for textile equipment.

[0007] The special fire extinguishing device for textile equipment described in the utility model includes a textile equipment, on which a fire extinguishing device is provided. A nozzle extending into the interior of the textile equipment is connected to the fire extinguishing device. A control module is provided inside the textile equipment, and the control module is connected to a manual controller. A pressure gauge and a fire detection tube are provided on the fire extinguishing device. The fire detection tubes are evenly arranged inside the textile equipment, and the fire extinguishing device is connected to the control module; a secondary fire extinguishing component is provided inside the fire extinguishing device.

[0008] Working process or principle:

[0009] During use, when a fire breaks out in a local area or at a certain point inside the textile equipment, the fire detection tube senses the flame temperature and ruptures. Subsequently, the fire extinguishing agent starts to be released from the rupture to implement fire extinguishing; after automatic activation, if it is found that the fire source has not been completely extinguished, it can still be manually activated, and the fire extinguishing agent is used for secondary fire extinguishing through the ruptured fire detection tube; when personnel discover that the textile equipment is on fire but the fire extinguishing device has not been activated yet, the manual controller can be pressed manually to activate the fire extinguishing device through the control module, so that the fire extinguishing agent is ejected from the nozzle.

[0010] The secondary fire extinguishing component includes a blasting aluminum film provided inside the fire extinguishing device. The blasting aluminum film divides the interior of the fire extinguishing device into an upper cavity and a lower cavity. A gas generating structure is provided at the bottom inside the fire extinguishing device. When the fire detection tube ruptures, the fire extinguishing agent in the upper cavity is transported to the original fire detection tube blasting hole for release. When secondary fire extinguishing is required, high-pressure gas is generated by controlling the gas generating mechanism, and the fire extinguishing agent in the lower cavity breaks through the blasting aluminum film and is ejected through the nozzle to achieve secondary fire extinguishing.

[0011] The gas generating structure includes a gas generating cavity. A gas cavity top plate is provided between the gas generating cavity and the lower cavity. The gas generating cavity is filled with a gas generating agent. The gas generating cavity is provided with an electric initiator connected to the control module. By triggering the electric initiator, a spark is generated to ignite the gas generating agent. The gas generating agent starts to convert from a solid state to a gaseous state, and the generated gas enters the lower cavity to cause the fire extinguishing agent in the lower cavity to break through the blasting aluminum film and be ejected through the nozzle.

[0012] The gas generating agent is a solid material that can generate high-pressure gas. The gas generating agent is composed of potassium perchlorate, ferrosilicon, aluminum powder, heavy glue, etc. mixed in equal proportions and is compacted into a cylindrical shape through a special mold. The compacted gas generating agent is coated with a coolant on the surface through a special cold process to achieve a cooling effect when the gas generating agent is released.

[0013] The fire extinguishing device is fixed on the outer wall of the textile equipment through a fixing frame, and being set on the outer wall facilitates the replacement of the fire extinguishing device.

[0014] The control module is connected to a fire alarm platform, and through the fire alarm platform, the staff can be quickly notified for fire prevention and control.

[0015] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0016] The present utility model operates automatically in a complete set from early warning, fire extinguishing to information feedback. With the addition of manual control, it is more reliable. The fire extinguishing device adopts a double-chamber structure. After automatic activation, it can still be manually activated for secondary fire extinguishing, effectively avoiding the problem that the fire reignites after the first fire extinguishing and the fire source cannot be effectively controlled.

Detailed Embodiments

[0021] Embodiment 1

[0022] As Figures 1 to 3As shown in the figure, the special fire extinguishing device for textile equipment of the present utility model includes a textile equipment 1, on which a fire extinguishing device 2 is provided. A nozzle 8 extending into the interior of the textile equipment 1 is connected to the fire extinguishing device 2. A control module 3 is provided inside the textile equipment 1. The control module 3 is connected to a manual controller 4. A pressure gauge 9 and a fire detection tube 7 are provided on the fire extinguishing device 2. The fire detection tubes 7 are evenly arranged inside the textile equipment 1. The fire extinguishing device 2 is connected to the control module 3. A secondary fire extinguishing component is provided inside the fire extinguishing device 2. The secondary fire extinguishing component includes a blasting aluminum film 11 provided inside the fire extinguishing device 2. The blasting aluminum film 11 divides the interior of the fire extinguishing device 2 into an upper cavity 10 and a lower cavity 12. A gas generating structure is provided at the bottom inside the fire extinguishing device 2. When the fire detection tube 7 breaks, the fire extinguishing agent in the upper cavity 10 is transported to the original blasting hole of the fire detection tube 7 for release. When secondary fire extinguishing is required, high-pressure gas is generated by controlling the gas generating mechanism, so that the fire extinguishing agent in the lower cavity 12 breaks through the blasting aluminum film 11 and is sprayed out through the nozzle 8 to achieve secondary fire extinguishing. The gas generating structure includes a gas generating cavity 14. A gas cavity top plate 13 is provided between the gas generating cavity 14 and the lower cavity 12. The gas generating cavity 14 is filled with a gas generating agent. The gas generating cavity 14 is provided with an electric initiator 15 connected to the control module 3. When the electric initiator 15 is triggered, a spark is generated to ignite the gas generating agent. The gas generating agent begins to convert from a solid state to a gaseous state, and the generated gas enters the lower cavity 12, causing the fire extinguishing agent in the lower cavity 12 to break through the blasting aluminum film 11 and be sprayed out through the nozzle 8. The gas generating agent is a solid material that can generate high-pressure gas. The gas generating agent is formed by mixing potassium perchlorate, ferrosilicon, aluminum powder, and heavy glue in equal proportions and compacted into a cylindrical shape through a special mold. The compacted gas generating agent is coated with a coolant on the surface through a special cold process to achieve a cooling effect when the gas generating agent is released. The fire extinguishing device 2 is fixed on the outer wall of the textile equipment 1 through a fixing frame 6. Setting it on the outer wall facilitates the replacement of the fire extinguishing device 2. The control module 3 is connected to a fire alarm platform 5. Through the fire alarm platform 5, the staff can be quickly notified to carry out fire prevention and control.

[0023] Working process or working principle:

[0024] During use, when a fire breaks out in a local area or at a certain point inside the textile equipment 1, the fire detection tube 7 senses the flame temperature and breaks. Subsequently, the fire extinguishing agent begins to be released from the break to implement fire extinguishing. After automatic activation, if it is found that the fire source has not been completely extinguished, manual activation can still be carried out. When the electric initiator 15 is triggered, a spark is generated to ignite the gas generating agent. The gas generating agent begins to convert from a solid state to a gaseous state, and the generated gas breaks through the gas cavity top plate 13 and enters the lower cavity 12, causing the fire extinguishing agent in the lower cavity 12 to break through the blasting aluminum film 11 and be sprayed out through the nozzle 8. When personnel discover that the textile equipment 1 is on fire but the fire extinguishing device 2 has not been activated yet, the manual controller 4 can be pressed manually to activate the fire extinguishing device 2 through the control module 3, so that the fire extinguishing agent is sprayed out from the nozzle 8.

[0025] The utility model operates automatically in a complete set from early warning, fire extinguishing to information feedback. With the addition of manual control, it is more reliable. The fire extinguishing device 2 adopts a double-chamber structure. After automatic activation, secondary fire extinguishing can still be carried out through manual activation, effectively avoiding the problem that the fire reignites after the first fire extinguishing and the fire source cannot be effectively controlled.

[0026] In the utility model, the description of the direction and relative position relationship of the structure, such as the description of front, back, left, right, up and down, does not constitute a limitation to the utility model, but is only for the convenience of description.
