Referring to fig. 1 and 2, the present invention provides an automatic fire extinguishing apparatus for expanded cut tobacco duplex dust collector, which comprises a duplex dust collector, a storage tank 15 and a control cabinet 17.
The duplex dust remover comprises a hopper 1 at the upper part and a dust collection box 3 at the lower part, and the hopper 1 is connected with the dust collection box 3 through a duplex airlock 2. The dust-containing gas enters the hopper 1, and under the action of centrifugal force, dust in the dust-containing gas enters the dust collection box 3 through the duplex air lock 2 to finish the dust removal process.
The storage tank 15 is arranged at the side edge of the duplex dust remover, and the storage tank 15 is used for storing carbon dioxide; a pipeline 8 is arranged above the storage tank 15, the other end of the pipeline 8 is connected with the upper part of the dust collection box 3, and a nozzle 12 is also arranged at the end part of the pipeline 8 positioned in the dust collection box 3; the pipeline 8 is also provided with a pneumatic control valve 5, and the pneumatic control valve 5 is electrically connected with a control cabinet 17.
The control cabinet 17 is positioned at the side of the duplex dust collector, the side wall of the dust collection box 3 is also provided with the flame sensor 10, the control cabinet 17 is electrically connected with the flame sensor 10, and when the flame sensor 10 detects that flame exists in the dust collection box 3, the control cabinet 17 can drive the pneumatic control valve 5 to be opened, so that carbon dioxide in the storage tank 15 enters the dust collection box 3 through the pipeline 8.
When the double-dust-collector fire extinguishing device is implemented, the double-dust-collector fire extinguishing device can effectively extinguish a fire in time when the double-dust-collector fire breaks out, and sends out sound and light alarms to workers. The fire source or the temperature in the dust collector is sensed through the flame sensor 10, and the signal is sent to the control cabinet 17, and the control cabinet 17 controls the communication of the pipeline 8 between the storage tank 15 and the dust collector, so that the carbon dioxide enters the dust collector along the pipeline 8 for fire extinguishing treatment.
Further, a pressure gauge 6 is arranged on the pipeline 8, and the pressure gauge 6 is used for detecting the circulation of the carbon dioxide. Whether the pipeline 8 is unblocked or not can be detected through the pressure gauge 6, and whether enough carbon dioxide still exists in the storage tank 15 or not can be preliminarily detected.
Further, a manual stop valve 7 is further provided on the pipe 8, and the manual stop valve 7 is located on the front side of the pneumatic control valve 5. When the flame sensor 10 gives a false alarm, so that the pneumatic air valve is open, or when there is no need to continue to deliver carbon dioxide, the operator can effect a shut-down by means of the manual shut-off valve 7.
Further, a metal hose 13 is connected to an end of the duct 8 remote from the storage tank 15, the metal hose 13 is connected to the dust box 3, and the nozzle 12 is connected to an end of the metal hose 13. The metal hose 13 facilitates adjustment of the position between the nozzle 12 and the dust box 3.
Further, the nozzle 12 is screwed to the metal hose 13, and a plurality of air holes 121 communicating with the metal hose 13 are formed in a side wall of the nozzle 12. Through seting up gas vent 121 on the lateral wall of nozzle 12 to change the flow direction of carbon dioxide, can make the gaseous pressure increase at the department of buckling, thereby the pressure grow when discharging from gas vent 121 does benefit to gaseous quick the discharge.
Still further, the lower surface of the nozzle 12 facing the bottom of the dust box 3 is of a closed structure. The side facing the bottom of the dust collection box 3 is in a closed state, and the fire extinguishing effect is achieved by means of the density of carbon dioxide, so that the problems that dust is blown to the bottom of the dust collection box 3 directly by the air holes 121 and the like is blown up are solved.
Furthermore, a double-layer filter screen 11 is arranged above the dust collection box 3, and the nozzle 12 is positioned below the double-layer filter screen 11. The double filter 11 serves on the one hand to prevent dust from escaping and to release excess air from the dust bin 3 during fire fighting and on the other hand to reduce the light entering the dust bin 3 and to avoid false alarms from the flame sensor 10.
Furthermore, the control cabinet 17 is also provided with an audible and visual alarm device 4, and when the flame sensor 10 detects that flame exists in the dust collection box 3, the control cabinet 17 drives the audible and visual alarm device 4 to start. The audible and visual alarm device 4 is used for reminding the operator in time.
Further, a base 14 composed of a plurality of support columns is arranged at the bottom of the storage tank 15, the height of the storage tank 15 is lifted by the base 14, so that a manual drain valve 16 is mounted on the lower surface of the storage tank 15, and the manual drain valve 16 is used for emptying the tank body. Since carbon dioxide has a higher density than air, carbon dioxide is deposited on the bottom of the storage tank 15 and can be discharged only from the bottom of the storage tank 15.
Still further, the upper surface of the storage tank 15 is also provided with a safety valve 9.
Although some specific embodiments of the present invention have been described in detail by way of examples, it should be understood by those skilled in the art that the above examples are for illustrative purposes only and are not intended to limit the scope of the present invention. It will be appreciated by those skilled in the art that modifications may be made to the above embodiments without departing from the scope and spirit of the utility model.
